The pressing end of the lock hook 33 is inserted into the release groove of the release push block 34, and the return spring drives the hook end of the lock hook 33 to rotate clockwise. The release groove is axially arranged on the side wall of the release push block 34, and the return spring drives the release push block 34 to move axially.

[0053] like Figure 1-Figure 4 As shown, the buffer device 4 includes a buffer block 41, a buffer damper 42 and a buffer fork 43. One end of the buffer damper 42 is fixed to the housing, and the other end cooperates with the buffer block 41. The buffer block 41 is arranged in the buffer slide groove of the housing to slide back and forth. The buffer fork 43 is located between the first rotating pendulum 11 and the second rotating pendulum 12. A fork gap is left between the support seats 11c and 12c of the two rotating pendulums. The buffer fork 43 is installed in the fork gap. The first rotating pendulum 11, the second rotating pendulum 12 and the buffer fork 43 are coaxially arranged (that is, they are all connected to the housing shaft through the shaft pin 14). The first rotating pendulum 11 or the second rotating pendulum 12 pushes the buffer fork 43 through the bearing, so that the buffer fork 43 moves the buffer block 41.

[0055] like Figure 9-10 As shown, the force adjustment device 5 includes an adjustment screw 51, an adjustment lever 52 and an adjustment spring 53. The adjustment spring 53 is sleeved on the second rod 22 and is separated from the second spring 22a by the rod body convex ring 22c on the second rod 22. One end of the adjustment lever 52 compresses the adjustment spring 53, and the other end cooperates with the adjustment nut 54. The adjustment nut 54 moves axially along the adjustment screw 51. The second rod 22 slides axially along the housing, and the adjustment lever 52 pushes the second rod 22 and compresses the adjustment spring 53.

[0056] The force adjustment device 5 includes a force indication sheet 55 and a force indication hole 56. The force indication hole 56 is arranged on the housing. Figure 1-Figure 3 As shown, a force scale is provided on the edge of the force indicating hole 56 , and the adjusting lever 52 pushes the force indicating sheet 55 to move back and forth in the force indicating hole 56 .

[0057] The working principle of the present invention is described below by taking the door opening-closing-opening working cycle as an example:

[0058] Initially, if Fig.11 As shown, the door body is in an open state, at this time, the buffer block 41 is pushed out of the shell by the buffer damper 42, and the first rotating pendulum member 11 and the second rotating pendulum member 12 are pushed to the cam groove 13a of the door pushing device 1 by the first sliding sleeve 21b and the second sliding sleeve 22b under the action of the first spring 21a and the second spring 22a respectively, and the blocking portion 31a of the block 31 of the locking release device 3 presses against the driving slider 21d of the first set rod 21, and the set rod fork 15 presses against the lever section 21c of the first set rod 21.

[0059] When closing the door, Fig.12As shown in FIG. 1 , the door body rotates to drive the first rotating pendulum 11 and the second rotating pendulum 12 to rotate out of the cam groove 13a, and push the first sliding sleeve 21b and the second sliding sleeve 22b, compressing the first spring 21a and the second spring 22a to complete energy storage. When the door body touches the buffer block 41, the closing speed slows down until the buffer block 41 retracts into the shell to compress the buffer damper 42, and the door body is completely closed. Fig.13 shown.

[0060] When the door is reopened, Fig.14 As shown, the door body is pressed, the push block 34 is released to drive the lock hook 33 to rotate so that the hook of the lock hook 33 is separated from the locking portion 31b of the block 31. At this time, the energy of the first spring 21a and the buffer damper 42 is released. The buffer block 41 is pushed out of the housing by the buffer damper 42. The first spring 21a pushes the first sleeve rod 21 to slide, overcomes the resistance of the blocking portion 31a of the block 31, and makes the block 31 rotate and compress the locking damper 32 and the reset spring of the lock hook 33. The first sleeve rod 21 slides along the sliding end surface of the block 31 and drives the sleeve rod fork 15 through the lever section 21c. At this time, the first rotating pendulum 11 and the second rotating pendulum 12 push the first sliding sleeve 21b and the second sliding sleeve 22b respectively, compressing the second spring 22a and the cavity spring 24.

[0061] like Fig.15 As shown, during the door opening process, when the door rotates to the cam groove 13a reaching the first rotating pendulum 11 and the second rotating pendulum 12, the energy of the second spring 22a and the cavity spring 24 is released, and the second spring 22a pushes the second sliding sleeve 22b to slide along the second set rod 22 and pushes the second rotating pendulum 12 to rotate, and at the same time, the cavity spring 24 drives the first sliding sleeve 21b to slide along the first set rod 21 in the same direction and pushes the first rotating pendulum 11 to rotate, until one end of the first rotating pendulum 11 and the second rotating pendulum 12 respectively sink into the cam groove 13a, and the door is completely opened. The buffer fork 43 pushes the buffer block 41 to return to the shell and compresses the buffer damper 42.

[0062] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the scope of protection of the present invention.
