A door body assembly 100 and a refrigerator 700 of a refrigerator 700 according to an embodiment of the present invention will be described below with reference to FIGS.

As shown in FIG. 1 to FIG. 6 , according to the door body assembly 100 of the refrigerator 700 according to the embodiment of the present invention, the door body assembly 100 of the refrigerator 700 includes: a door body 10, a hinge fixing plate 20, a hinge shaft 30, and a sleeve 40. Position member 60 and screw 50.

Specifically, as shown in FIGS. 1 to 6, the hinge fixing plate 20 is spaced apart from the door body 10, and the hinge shaft 30 is fixed to the hinge fixing plate 20. The door body 10 is provided with a mounting groove 110. One end of the hinge shaft 30 extends into the mounting groove 110. The hinge shaft 30 is provided with a threaded through hole 320 extending through the axis. The sleeve 40 is located in the mounting groove 110, and the sleeve 40 is disposed at one end of the hinge shaft 30. The limiting member 60 is disposed in the sleeve 40 between the sleeve 40 and one end of the hinge shaft 30. The limiting member 60 is provided with a first limiting portion 610, and the hinge shaft 30 is provided with a second limiting portion 310. The first limiting portion 610 cooperates with the second limiting portion 310 to define that the limiting member 60 is movable relative to the hinge shaft 30 in the axial direction thereof. The screw 50 is bored in the threaded through hole 320, and one end of the screw 50 passes through one end of the hinge shaft 30 and abuts against the stopper 60.

For example, as shown in the example of FIG. 3, the hinge fixing plate 20 may be spaced apart from the door body 10, and the left end of the hinge fixing plate 20 may be fixed to the housing 710 of the refrigerator 700. A hinge shaft 30 may be fixedly disposed on the hinge fixing plate 20, and the inside of the hinge shaft 30 has a threaded through hole 320 penetrating in the axial direction of the hinge shaft 30 (ie, the up and down direction shown in FIG. 3). The screw 50 is threaded into the threaded through hole 320 by a threaded connection. The lower end of the door body 10 is provided with an opening downwardly facing the mounting groove 110. The mounting groove 110 can be a cylindrical hole, and the sleeve 110 is embedded in the mounting groove 110. The sleeve 40 is disposed at the upper end of the hinge shaft 30, and a limiting member 60 is disposed between the sleeve 40 and the hinge shaft 30. For example, the limiting member 60 can be fixedly connected to the inner top wall of the sleeve 40, that is, the relative movement between the limiting member 60 and the sleeve 40 cannot occur; the limiting member 60 can also be clamped on the sleeve 40 and the hinge shaft. Between 30, and between the limiting member 60 and the sleeve 40 is not fixed, that is, the limiting member 60 and the sleeve 40 can move relative to each other. The upper end of the limiting member 60 abuts against the top wall of the sleeve 40, and the lower end of the limiting member 60 abuts against the upper end of the screw 50.

As shown in FIG. 5, the lower end of the limiting member 60 is provided with a first limiting portion 610. Correspondingly, a second limiting portion corresponding to the first limiting portion 610 is disposed on the inner peripheral wall of the hinge shaft 30. 310. The first limiting portion 610 cooperates with the second limiting portion 310 to define that the limiting member 60 is movable relative to the hinge shaft 30 in the axial direction thereof (ie, the up and down direction shown in FIG. 5), and can prevent the limiting member 60 rotates relative to the hinge shaft 30.

It should be noted that, as shown in FIG. 3 , the hinge fixing plate 20 is fixed on the casing 710 of the refrigerator 700 , and the hinge shaft 30 is fixedly connected with the hinge fixing plate 20 . Therefore, the hinge shaft 30 and the hinge fixing plate 20 are opposite to the refrigerator 700 . The housing 710 is always stationary. The screw 50 is threaded into the threaded through hole 320 of the hinge shaft 30, and the hinge shaft 30 can be screwed with the screw 50, that is, the screw 50 can be rotated relative to the hinge shaft 30 when the screw 50 is rotated relative to the hinge shaft 30. The screw 50 is also moved relative to the hinge shaft 30 in its axial direction (i.e., the up and down direction shown in FIG. 3). For example, when the screw 50 is rotated relative to the hinge shaft 30 (for example, the screw 50 is rotated clockwise with respect to the hinge shaft 30), the screw 50 is downward in the axial direction (i.e., the up and down direction shown in FIG. 3) with respect to the hinge shaft 30. Moving; when the screw 50 is rotated relative to the hinge shaft 30 (for example, the screw 50 is rotated counterclockwise with respect to the hinge shaft 30), the screw 50 is moved upward relative to the hinge shaft 30 in the axial direction thereof (i.e., the up and down direction shown in FIG. 3). .

Since the screw 50 is movable relative to the hinge shaft 30 in its axial direction (i.e., the up and down direction shown in FIG. 3), the stopper 60 engaged with the screw 50 can also move as the screw 50 moves. It should be noted that, as shown in FIG. 5, a first limiting portion 610 is disposed on the limiting member 60, and a second limiting portion 310 adapted to the first limiting portion 610 is disposed on the hinge shaft 30. The limiting fit between the first limiting portion 610 and the second limiting portion 310 can prevent the limiting member 60 from rotating relative to the hinge shaft 30 in the circumferential direction, so that the limiting member 60 can be along the hinge axis 30. The axial direction (i.e., the up and down direction shown in Fig. 5) moves. For example, as shown in FIG. 3, when the screw 50 moves upward, the screw 50 can drive the limiting member 60 to move upward, and the limiting member 60 can drive the sleeve 40 and the door body 10 to move upward; when the screw 50 moves downward. The door body 10 moves downward with the movement of the screw 50 under the action of its own gravity.

Thereby, the elevation adjustment of the height of the door body 10 in the up and down direction can be achieved. Therefore, when the door body 10 of the refrigerator 700 is displaced in the up and down direction due to long-term use, or the size error caused by the production of the door body 10 causes the heights of the left and right door bodies 10 of the refrigerator 700 to be inconsistent, the refrigerator 700 can be adjusted. The door body assembly 100 conveniently adjusts the height of the door body 10 to maintain the overall appearance of the refrigerator 700.

According to the door assembly 100 of the refrigerator 700 according to the embodiment of the present invention, when the screw 50 is rotated, the screw 50 can be moved in the up and down direction. Since the upper end of the screw 50 is opposite to the limiting member 60, the upper end of the limiting member 60 is embedded. The sleeve 40 provided in the mounting groove 110 of the door body 10 abuts. Therefore, when the screw 50 moves in the up and down direction, the limiting member 60 can be moved in the vertical direction, and the limiting member 60 drives the sleeve 40 and the door body 10 to move in the up and down direction, thereby realizing the lifting and lowering of the height of the door body 10 in the up and down direction. The utility model has the advantages of simple structure, convenient operation, and effectively overcomes the problem that the height of the door body 10 of the refrigerator 700 does not affect the overall aesthetics of the refrigerator 700.

According to some embodiments of the present invention, as shown in FIG. 5, the first limiting portion 610 is a limiting post 611, and the limiting post 611 extends from the end of the limiting member 60 toward the hinge fixing plate 20, that is, in FIG. As shown, the limit post 611 extends from the lower end of the stop member 60 and extends downward. The second limiting portion 310 is a limiting groove 311 extending along the axis of the hinge shaft 30. As shown in FIG. 5, an axial direction of the hinge shaft 30 is formed on the inner peripheral wall of the hinge shaft 30 (ie, as shown in FIG. 5). The limiting groove 311 extends in the up and down direction, and the limiting post 611 is movable along the limiting groove 311. It can be understood that, as shown in FIG. 5, when the limiting post 611 of the limiting member 60 extends into the limiting groove 311 of the hinge shaft 30, the limiting post 611 can move up and down along the limiting groove 311. Thereby, the stopper 60 can be moved up and down with respect to the hinge shaft 30, and relative rotation between the stopper 60 and the hinge shaft 30 can be prevented. Therefore, when the screw 50 rotates, the screw 50 moves up and down relative to the hinge shaft 30 to move the stopper 60 in the vertical direction, thereby driving the sleeve 40 and the door body 10 to move up and down. Moreover, it is possible to effectively prevent the height of the door body 10 from being changed by rotating the stopper 60 relative to the hinge shaft 30 when the door body 10 is rotated.

Further, the limiting recesses 311 are plural, and the plurality of limiting recesses 311 are spaced apart in the circumferential direction of the hinge shaft 30. The plurality of limiting posts 611 are in plurality, and the plurality of limiting posts 611 are in one-to-one correspondence with the plurality of limiting recesses 311. As shown in FIG. 5, two restriction grooves 311 extending in the axial direction of the hinge shaft 30 (i.e., the up and down direction shown in FIG. 5) are provided on the inner peripheral wall of the hinge shaft 30, and correspondingly, The lower end of the limiting member 60 is symmetrically disposed with two limiting posts 611 extending downward. The two limiting posts 611 can be correspondingly extended into the limiting groove 311, so that the limiting member 60 can move up and down with respect to the hinge axis 30, and the limiting member 60 can be prevented from rotating relative to the hinge shaft 30. Of course, the limiting recesses 311 can also be configured in plurality, and correspondingly, the limiting pillars 611 are disposed in plurality, and are in one-to-one correspondence with the limiting recesses 311.

In some embodiments of the invention, the cross-section of the limiting post 611 may be circular, elliptical or polygonal. In other words, the limit post 611 can be configured as a cylindrical shape, an elliptical cylindrical shape, or other polyhedral shape. For example, as shown in the example in FIG. 5, two downwardly extending limiting posts 611 are symmetrically disposed at the lower end of the limiting member 60. The limiting post 611 is a rectangular parallelepiped cylindrical shape, and between the sidewalls of the limiting post 611 Can be set with chamfering. The positioning of the limiting post 611 into a rectangular cylinder shape facilitates the manufacturing of the limiting post 611, thereby reducing the processing cost of the limiting member 60.

According to some embodiments of the present invention, as shown in FIG. 3, a receiving groove 620 may be disposed on an end surface of the limiting member 60 facing the screw 50. That is, the lower end of the limiting member 60 may be provided with a receiving groove 620, and the receiving groove 620 may be of a circular hole type, and the upper end of the screw 50 may protrude into the receiving groove 620. Thus, when assembling the door body assembly 100 of the refrigerator 700, The accommodating groove 620 can serve as a guiding position for facilitating the assembly and fixing between the screw 50 and the limiting member 60, and the accommodating groove 620 is disposed at the upper end of the screw 50, and can be displaced when the screw 50 rotates in the up and down direction. The stable driving limiter 60 moves in the up and down direction.

According to some embodiments of the present invention, the wall surface of the sleeve 40 opposite the one end of the screw 50 may have a cushioning curved surface 410. For example, as shown in the example in FIG. 3, a buffer curved surface 410 is disposed on the inner top wall of the sleeve 40 opposite to the screw 50, and the buffer curved surface 410 is formed as a downward convex portion, and the lower end of the buffer curved surface 410 and the limiting member are formed. The upper end of 60 is offset. Thus, when the screw 50 rotates in the threaded through hole 320, for example, when the screw 50 rotates counterclockwise, the screw 50 moves upward relative to the hinge shaft 30, and the upper end of the screw 50 abuts against the limiting member 60. Therefore, the screw 50 can The limiting member 60 is moved upward. The upper portion of the limiting member 60 is opposite to the buffering surface 410. When the limiting member 60 moves upward, the limiting member 60 presses the buffering surface 410 upwardly and drives the sleeve 40 and the door body 10 to move upward relative to the hinge shaft 30. The buffer surface 410 is disposed on the sleeve 40 to absorb the upward pressing force of the buffer limiting member 60 on the sleeve 40, and the upward pressing force of the limiting member 60 is prevented from causing fatigue damage to the sleeve 40 and the door body 10.

In some embodiments of the present invention, the sleeve 40 may have a flange 420 near the periphery of the hinge fixing plate 20, and the flange 420 is located outside the mounting groove 110. For example, as shown in the example of FIG. 3, an annular flange 420 is disposed at the lower end of the sleeve 40. The upper end of the flange 420 abuts the lower end of the door body 10, and the sleeve 40 can be welded or bonded to the door by the annular flange 420. In the body 10, to ensure the stability of the fixing between the sleeve 40 and the door body 10, the sleeve 40 can also be embedded inside the mounting groove 110 of the door body 10. When the screw 50 rotates upward to drive the limiting member 60 to move upward, the limiting member 60 generates an upward pressing force on the sleeve 40, and the annular flange 420 at the lower end of the sleeve 40 can disperse the pressing force, so that the sleeve 40 is opposite to the door body. The upward thrust of 10 is more uniform to drive the door body 10 to move upward.

According to some embodiments of the present invention, the end face of the other end of the screw 50 is provided with an adjustment groove 510 having a "+" shape or a "-" shape. For example, as shown in the example of FIG. 6, an adjustment groove 510 is provided at the lower end of the screw 50 (up and down direction as shown in FIG. 6), and the shape of the adjustment groove 510 is "+" shape, in other embodiments of the present invention. In the example, the adjustment groove 510 can also be set to a "-" shape. Therefore, the screw 50 can be twisted from the lower end of the screw 50 by using a cross-shaped or a flat-shaped screwdriver to realize the up-and-down movement of the screw 50, thereby driving the limiting member 60 to move up and down, and the limiting member 60 drives the sleeve 40 and the door body. 10 moves in the up and down direction to adjust the height of the door body 10, and the operation is convenient and the adjustment is flexible.

According to some embodiments of the present invention, the other end of the hinge shaft 30 has an annular mounting groove 330 in which the hinge fixing plate 20 is seated. For example, as shown in the example of FIG. 3, an annular mounting groove 330 may be provided at the lower end of the hinge shaft 30, that is, an annular mounting groove 330 having a radial radius smaller than a radial radius at the remaining position at the lower end of the hinge shaft 30, the ring shape The height of the mounting groove 330 in the up and down direction (up and down direction as shown in FIG. 3) is equal to the thickness at the position where the hinge fixing plate 20 is fitted with the hinge shaft 30 (that is, the thickness of the hinge fixing plate 20 shown in FIG. 3 in the up and down direction). Therefore, the hinge shaft 30 can be stably fixed on the hinge fixing plate 20 to prevent the hinge shaft 30 from being interposed between the hinge shaft 30 and the hinge fixing plate 20. Relatively moving. It is to be understood that the hinge fixing plate 20 may include two pieces that are divided along the axial direction of the hinge shaft 30, and the two hinge fixing plates 20 abut the fitting holes of the hinge shaft 30 to be matched with the annular mounting groove 330, thereby The hinge fixing plate 20 is snapped into the annular mounting groove 330 of the hinge shaft 30.

In other embodiments of the present invention, the hinge shaft 30 can also be fixedly mounted on the hinge fixing plate 20 by a riveted joint, whereby the stability of the connection between the hinge shaft 30 and the hinge fixing plate 20 can be enhanced, and the hinge shaft can be prevented. A relative movement occurs between the 30 and the hinge fixing plate 20. Of course, the hinge shaft 30 and the hinge fixing plate 20 can also be fixedly assembled by welding or other connection.

The door body assembly 100 of the refrigerator 700 according to the present invention will now be described in detail with reference to FIGS. 1 through 6 in a specific embodiment. It is to be understood that the following description is only illustrative and not restrictive.

As shown in FIGS. 1 to 6, the door assembly 100 of the refrigerator 700 includes a door body 10, a hinge fixing plate 20, a hinge shaft 30, a sleeve 40, a stopper 60, and a screw 50.

Here, as shown in FIG. 1, two door bodies 10 are provided above the refrigerator 700 in the left-right direction (the left-right direction as shown in FIG. 1). A hinge fixing plate 20 (shown in FIG. 2) is provided spaced below the door body 10, and the hinge fixing plate 20 is fixedly coupled to the housing 710 of the refrigerator 700. As shown in FIG. 3, a hinge shaft 30 is fixed on the hinge fixing plate 20. The lower end of the hinge shaft 30 is provided with an annular mounting groove 330, and the hinge fixing plate 20 is locked in the annular mounting groove 330. The inside of the hinge shaft 30 is provided with a threaded through hole 320 penetrating in the axial direction of the hinge shaft 30 (i.e., the up and down direction shown in Fig. 3). The screw 50 is screwed into the threaded through hole 320, and the lower end of the screw 50 is provided with a "+" shaped adjustment groove 510 (shown in Fig. 6).

As shown in FIG. 3, a cylindrical mounting groove 110 is provided at the lower end of the door body 10, and a bushing 40 is embedded in the mounting groove 110. The lower end of the sleeve 40 is provided with an annular flange 420. The sleeve 40 is disposed above the hinge shaft 30. The inner top wall of the sleeve 40 is disposed at a position opposite to the hinge shaft 30 with a buffer curved surface 410. A limiting member 60 is disposed between the buffering curved surface 410 and the screw 50. The upper end of the limiting member 60 is opposite to the buffering curved surface 410. The lower end of the limiting member 60 is provided with a receiving groove 620. The upper end of the screw 50 extends into the receiving groove 620. It is opposite to the limiting member 60.

As shown in FIG. 5, two downwardly extending limit posts 611 are symmetrically disposed at the lower end of the retaining member 60, and correspondingly, the inner peripheral wall of the hinge shaft 30 is disposed along the axial direction of the hinge shaft 30 (ie, The upper and lower directions shown in FIG. 5 are symmetrically disposed with two limiting grooves 311. The limiting post 611 is a rectangular parallelepiped cylinder, and the limiting post 611 is matched with the limiting recess 311 to limit the movement of the limiting member 60 in the up and down direction and prevent relative rotation between the limiting member 60 and the hinge shaft 30. .

It should be noted that, as shown in FIG. 3 , the hinge fixing plate 20 is fixed on the casing 710 of the refrigerator 700 , and the hinge shaft 30 is fixedly connected with the hinge fixing plate 20 . Therefore, the hinge shaft 30 and the hinge fixing plate 20 are opposite to the refrigerator 700 . The housing 710 is always stationary. The screw 50 is disposed in the threaded through hole 320 of the hinge shaft 30, and the hinge shaft 30 can be screwed 50 is screwed, that is, the screw 50 is rotatable relative to the hinge shaft 30, and when the screw 50 is rotated relative to the hinge shaft 30, the screw 50 is also moved relative to the hinge shaft 30 in its axial direction. For example, when the screw 50 is rotated relative to the hinge shaft 30 (for example, the screw 50 is rotated clockwise with respect to the hinge shaft 30), the screw 50 is downward in the axial direction (i.e., the up and down direction shown in FIG. 3) with respect to the hinge shaft 30. Moving; when the screw 50 is rotated relative to the hinge shaft 30 (for example, the screw 50 is rotated counterclockwise with respect to the hinge shaft 30), the screw 50 is moved upward relative to the hinge shaft 30 in the axial direction thereof (i.e., the up and down direction shown in FIG. 3). .

Since the screw 50 is movable relative to the hinge shaft 30 in its axial direction (i.e., the up and down direction shown in FIG. 3), the stopper 60 engaged with the screw 50 can also move as the screw 50 moves. It should be noted that, as shown in FIG. 5, a first limiting portion 610 is disposed on the limiting member 60, and a second limiting portion 310 adapted to the first limiting portion 610 is disposed on the hinge shaft 30. The limiting fit between the first limiting portion 610 and the second limiting portion 310 can prevent the limiting member 60 from rotating relative to the hinge shaft 30 in the circumferential direction, so that the limiting member 60 can be along the hinge axis 30. The axial direction (i.e., the up and down direction shown in Fig. 5) moves. For example, as shown in FIG. 3, when the screw 50 moves upward, the screw 50 can drive the limiting member 60 to move upward, and the limiting member 60 can drive the sleeve 40 and the door body 10 to move upward; when the screw 50 moves downward. The door body 10 moves downward with the movement of the screw 50 under the action of its own gravity.

Thereby, the elevation adjustment of the height of the door body 10 in the up and down direction can be achieved. Therefore, when the door body 10 of the refrigerator 700 is displaced in the up and down direction due to long-term use, or the size error caused by the production of the door body 10 causes the heights of the left and right door bodies 10 of the refrigerator 700 to be inconsistent, the refrigerator 700 can be adjusted. The door body assembly 100 conveniently adjusts the height of the door body 10 to maintain the overall appearance of the refrigerator 700.

A refrigerator 700 according to an embodiment of the present invention includes the door body assembly 100 of the refrigerator 700 described above.

According to the refrigerator 700 of the embodiment of the present invention, when the screw 50 of the door assembly 100 is rotated, the screw 50 can be moved in the up and down direction. Since the upper end of the screw 50 abuts against the limiting member 60, the upper end of the limiting member 60 is embedded. The sleeve 40 provided in the mounting groove 110 of the door body 10 abuts. Therefore, when the screw 50 moves in the up and down direction, the upper direction of the limiting member 60 can be moved, and the limiting member 60 drives the sleeve 40 and the door body 10 to move in the up and down direction, thereby realizing the lifting and lowering of the height of the door body 10 in the up and down direction. The utility model has the advantages of simple structure, convenient operation, and effectively overcomes the problem that the height of the door body 10 of the refrigerator 700 does not affect the overall aesthetics of the refrigerator 700.
