Description

hanger mechanism

technical field

The utility model relates to a hanger mechanism, in particular to a hanger mechanism for stably and safely transporting patients.

Background technique

The general patient transport rack has tripods on both sides of the base. When the patient transport rack transports the patient and wants to enter the door of the ward, according to the existing operating structure, the medical staff will hold it with their hands. The crank handle on the rear side is reciprocated left and right to gradually retract the bipod set on the bottom side of the transport frame, so that the bottom side frame of the transport frame can enter and exit the door of the ward.

However, it is not only inconvenient to operate but also quite laborious to use the hand to hold the crank handle on the rear side and shake it back and forth left and right to fold and unfold the bipod on the bottom side of the carrier. Therefore, the existing improved structure is that the bipod designed as a transport frame can be folded and unfolded through the pedaling action of the human foot, but usually there is only a pedal-folding and unfolding structure without an automatic positioning, folding and unfolding structure Due to the function, the folded and unfolded state of the two feet of the patient hanger base is often affected by external force collision displacement, affecting the nursing staff to carry the patient and causing danger.

Detailed ways

Referring to Fig. 1 and Fig. 2, it is a perspective view and a partial exploded view of the hanger mechanism of a preferred embodiment. Shown in the figure is a hanger mechanism for carrying patients, which is mainly composed of an upper half and a lower half, wherein the upper half includes a main rod 11, a rotating rod 12, a telescopic member 13, and a boom 14 , and a hanging bag 15, the lower half includes a pair of tripods 21,22, a connecting rod 23, a swing plate 24, a stud 25, an elastic member 26, a pair of pedal arms 27,28, a pivot Column 29 , a positioning piece 30 , a pair of driving connecting rods 31 , 32 , and a sleeve 33 .

The main rod 11 extends upward from the connecting rod 23 , and the two ends of the rotating rod 12 are pivotally connected to the main rod 11 and the boom 14 respectively. The rotating rod 12 is pivotally connected to the middle part of the boom 14, and the two ends 141, 142 of the boom 14 are hooked by the fixed ropes 152, 153 of the hanging bag 15, and the carrying bag surface 151 of the hanging bag 15 is used for carrying the disease suffer from. One end of the telescopic member 13 is fixed to the main rod 11, and the other end is pivotally connected to the rotating rod 12. Through the outward stretching movement of the telescopic member 13, the rotating rod 12 can be lifted up and rotated, thereby making the hanging bag 15 and the patient on it be raised.

The connecting rods 23 are respectively pivoted on the tripods 21, 22, thereby defining the pivot axes X1, X2 of the tripods 21, 22, and each tripod is respectively provided at both ends of its own pivot axis. There are rolling wheels W for easy handling.

The swing plate 24 is T-shaped and includes a head 241 and a foot 242 extending downward from the middle of the head. The swing plate 24 is pivotally mounted on the connecting rod 23 by its leg portion 242 , thus defining a pivot axis X5 . The two driving links 31 , 32 are respectively pivoted on the swing plate 24 with their input ends 311 , 321 , and are respectively located on the upper and lower sides of the pivot axis X5 , thus defining the pivot axes X6 , X7 . The two driving links 31 , 32 are also pivotally mounted on the legs 21 , 22 with their output ends 312 , 322 , thereby defining the pivot axes X3 , X4 .

The two pedal arms 27 , 28 are respectively pivoted on the head 241 of the T-shaped wobble plate 24 , and are located on opposite sides of the wobble plate pivot axis X5 , thereby defining the pivot axes X8 , X9 . The pedal arm 27 (28) includes a pedal end 271 (281) located on the left and right sides of the pivot axis X8 (X9) and an actuating end 272 (282). A protruding strip-shaped pedal 273 (283) is arranged.

The pivot 29 passes through the actuating ends 272 , 282 of the two pedal arms 27 , 28 and the stud 25 at the same time. The sleeve 33 is screw-locked and fixed on the swing plate 24 , and the stud 25 is set loosely in the sleeve 33 . In this example, the elastic member 26 is a spring, which is sleeved on the stud 25. One end of the spring abuts against the flange portion 251 of the stud 25, and the other end abuts against the sleeve 33, thereby imparting a force to the stud 25. Pre-force.

The positioning piece 30 is locked on the connecting rod 23 by bolts, and a plurality of positioning slots 301 , 302 are defined on the positioning piece 30 for the above-mentioned stud 25 to be selectively inserted into and locked.

In this embodiment, the pivot axes X1, X2, X3, X4 are roughly parallel to the height direction of the hanger mechanism, and the pivot axes X5, X6, X7, X8, X9 are roughly parallel to the length direction of the hanger mechanism.

Referring to Fig. 3 to Fig. 6, it is a series of schematic diagrams of the movement of the hanger mechanism from the folded state to the unfolded state. It can be seen in Fig. 3 that the hanger mechanism is in the retracted state. At this time, because the stud 25 is inserted into one of the positioning slots 301 of the positioning piece 30, the swing plate 24 inclined to the left is locked and unable to rotate, and the drive link 31 , 32 and tripod 21,22 are thus locked.

When an external force is applied to the pedal end 281 of the pedal arm 28 (such as pressing the pedal 283 with a person's foot), the pedal arm 28 pivots at this moment, and then drives the stud 25 through the pivot 29 to resist the upward movement of the elastic member 26 , the wobble plate 24, the drive links 31, 32, and the legs 21, 22 are thus released, as shown in FIG.

When the external force continues to be strengthened to cause the swing plate 24 to rotate to the right, at this moment, the two driving links 31, 32 drive the corresponding tripods 21, 22 in response to the rotation of the swing plate 24, so that the tripods 21, 22 are outward Expand, as shown in Figure 5.

Finally, the external force is removed, so that the stud 25 returns to the other positioning slot 302 of the positioning piece 30 due to the pre-force of the elastic member 26, and the legs 21, 22 are deadlocked again, as shown in FIG. 6 .

From the above, it can be seen that the utility model can exert the effect that the legs of the hanger mechanism can be positioned in the folded state or the unfolded state, and enhance the safety in use. Moreover, the folding and unfolding of the tripod can be operated only by stepping on different pedal arms with the feet, which is very convenient.

The above-mentioned embodiments are only examples for convenience of description, and the scope of rights claimed by the utility model shall be subject to the scope of the patent application, rather than limited to the above-mentioned embodiments.
