The working principle of the invention is described below by taking the working cycle of opening-closing-opening the door body as an example:
Initially, as shown in fig. 11, the door body is in an open state, at this time, the buffer block 41 is ejected out of the housing by the buffer damper 42, the first swing piece 11 and the second swing piece 12 are respectively pushed into the cam groove 14 positioned in 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, and the blocking portion 31a of the stop block 31 of the lock release device 3 abuts against the driving slider 21d of the first loop bar 21, and the loop bar fork 15 abuts against the pulling bar section 21c of the first loop bar 21.
When the door body is closed, as shown in fig. 12, the door body rotates to drive the first swing piece 11 and the second swing piece 12 to rotate and separate from the cam groove 14, and push the first sliding sleeve 21b and the second sliding sleeve 22b, compressing the first spring 21a and the second spring 22a, and completing energy storage. When the door body touches the damper block 41, the closing speed is slowed down until the damper block 41 is retracted into the housing to compress the damper 42, and the door body is completely closed as shown in fig. 13.
When the door body is reopened, as shown in fig. 14, the door body is pressed, and the release push block 34 drives the latch hook 33 to rotate so that the clasp of the latch hook 33 is separated from the locking portion 31b of the stopper 31, and at this time, the energy of the first spring 21a and the buffer damper 42 is released. The buffer block 41 is ejected 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 part 31a of the block 31, enables the block 31 to rotate and compress the locking damper 32 and the reset spring of the lock hook 33, and the first sleeve rod 21 slides along the sliding end surface of the block 31 and drives the sleeve rod shifting fork 15 through the shifting rod section 21 c; at this time, the first swing piece 11 and the second swing piece 12 push the first sliding sleeve 21b and the second sliding sleeve 22b, respectively, compressing the second spring 22a and the cavity spring 24.
As shown in fig. 15, in the opening process of the door body, when the door body rotates until the cam groove 14 reaches the first swing piece 11 and the second swing piece 12, the energy of the second spring 22a and the cavity spring 24 is released, the second spring 22a pushes the second sliding sleeve 22b to slide along the second sliding rod 22 and push the second swing piece 12 to rotate, and meanwhile, the cavity spring 24 drives the first sliding sleeve 21b to slide along the first sliding rod 21 in the same direction and push the first swing piece 11 to rotate until one end of the first swing piece 11 and one end of the second swing piece 12 are respectively sunk into the cam groove 14, so that the door body is completely opened. The buffer fork 43 pushes the buffer block 41 to be restored into the housing, and compresses the buffer damper 42.
The foregoing is merely a preferred embodiment of the present invention, and it should be noted that modifications and substitutions can be made by those skilled in the art without departing from the technical principles of the present invention, and these modifications and substitutions should also be considered as being within the scope of the present invention.
