 The technical solution adopted by the utility model to solve the technical problem is: a coffee machine top cover locking mechanism, comprising a top cover body, a sliding block and a locking groove, the rear end of the top cover body being hinged to the main body of the coffee machine, The sliding block of the locking pin is disposed on the top cover body and correspondingly engages with the locking groove disposed on the main body of the coffee machine, and is characterized in that: a plane rocker mechanism composed of a driving rod and a driven rod is provided, One end of the driving rod and the driven rod are articulated, and the other ends of the driving rod and the driven rod are respectively hingedly coupled with the top cover body and the sliding block. '

 The top cover body comprises a top cover outer casing and a top cover base, the top cover outer casing and the top cover base are fixedly connected, and the top cover outer casing is provided with a sliding groove corresponding to the movement track of the driving rod, the sliding The shifting block is disposed on the base of the top cover, and the driving rod is hinged to the base of the top cover.

 The driving rod and the driven rod are hinged at one end to be provided with a thrust handle.

 The end of the driving rod and the driven rod is provided with an arc-shaped guiding plate.

 The drive rod and the follower rod are disposed on the same side of their common hinge points.

There is also a return spring, the top cover base and the sliding block are correspondingly provided with a spring top block and a spring receiving cavity, and the return spring is disposed in the spring receiving cavity, the two ends of which correspond to the spring top block and the spring capacity The bottom surface of the cavity is offset. The beneficial effect of the actual 13⁄4 is that the ϊ ϊ ϋ 3⁄4 way, through the interaction of the drive rod and the follower rod, the sliding block is moved to realize the locking and opening of the top cover, so that the user can open the top of the coffee machine. There are new options in the way, and the structure is simple and easy to operate.

detailed description

 The present invention will be further described below in conjunction with the accompanying drawings.

 Before describing the present embodiment in detail, the structure of the prior art related to the present embodiment will be described.

 Referring to FIG. 1 and FIG. 2, the top cover of most existing coffee machines is provided with a sliding slot 110 on the top cover body 11, and a sliding block 10 provided with the locking pin 100 moves in the sliding slot 110 through the locking pin. 100 slides in/out the locking groove 20 provided on the main body 2 of the coffee machine to achieve its locking or opening.

 The present embodiment will be described below. See Figure 3 through Figure 7. The coffee machine top cover locking mechanism includes a top cover body, a slip block 10, and a locking recess (not shown) on the main body of the coffee machine.

 The top cover main body of the embodiment includes a top cover outer casing 12 and a top cover base 13. The top cover outer casing 12 and the top cover base 13 are fixedly connected. At the rear of the outer casing 12, an articulated arm 120 is provided. The articulated arm 120 is articulated to the coffee machine body (not shown).

 The sliding block 10 is provided with a locking pin 100, which is movably disposed on the top cover base 13 so as to be adapted to be engaged with a locking groove (not shown) provided on the main body of the coffee machine;

The utility model is characterized in that: a plane rocker mechanism composed of a driving rod 30 and a raking rod 3i is provided, and one ends of the driving rod 30 and the driven rod 31 are articulated, and the other ends of the driving rod 30 and the driven rod 31 respectively correspond to the top cover Base 13 and sliding ± 10 movable hinges. - The drive rod 30 and the follower rod 31 are disposed on the same side of their common hinge point 300. Accordingly, the top cover casing 12 is provided with a slip groove 121 corresponding to the movement locus of the drive rod 30.

 A thrust handle 301 is provided at one end of the drive lever 30 hinged to the follower lever 31. The end of the drive rod 30 hinged to the driven rod 31 is provided with an arc-shaped guide plate 302.

 There is also a return spring 4, and the top cover base 13 and the sliding block 10 are correspondingly provided with a spring top block 130 and a spring receiving cavity 101. The return spring 4 is disposed in the spring receiving 101, and the two ends thereof correspond to The spring top block 130 abuts against the bottom surface of the spring receiving cavity 101.

 The operation procedure of the present invention is as follows: When the driving rod 30 and the driven rod 31 are in the position shown in FIG. 6, the driving rod 30 and the driven rod 31 are in the same straight line as the moving path of the sliding block 10, and the plane rocker mechanism In the dead angle position, the slip block 10 is locked. When the driving lever 30 is rotated by the thrust handle 301, the common hinge point of the driving lever 30 and the driven lever 31 is away from the blind spot position, and under the traction of the driven lever 31, the sliding block 10 is gradually moved away from the locking groove (not shown) ), to achieve unlocking.

 The specific embodiments described above are merely preferred embodiments of the present invention, and equivalent designs made by the scope of the present invention should be covered by the technology of the present invention.
