In some specific examples of the present invention, as shown in fig. 1, 2 and 4, the one end of the rocker arm 500 is provided with a fork head 560, the fork head 560 is provided with a guide post 561 disposed oppositely, the outer peripheral surface of the rotation pin 200 is provided with an annular groove 220 extending along the circumferential direction thereof, the guide post 561 is fitted to the annular groove 220, so that when the rotation pin 200 is extended or retracted, the rocker arm 500 can be driven to swing around the rotation axis thereof, and the fork head 560 and the rotation pin 200 are formed to be rotatably fitted in two directions, one direction is that the fork head 560 can rotate around the axial direction of the guide post 561 relative to the rotation pin 200, and the other direction is that the rotation pin 200 can rotate around the axial direction thereof relative to the fork head 560, whereby the fitting of the fork head 560 to the rotation pin 200 does not hinder the extension or retraction and rotation.

Further, as shown in fig. 3, a first stopper 113 and a second stopper 114 are provided in the case body 110 of the mounting case 100, the first stopper 113 and the second stopper 114 may be oppositely disposed in the radial direction of the guide hole 115, and the fork head 560 is interposed between the first stopper 113 and the second stopper 114, thereby preventing the fork head 560 of the swing arm 500 from swinging in the radial direction of the rotation pin 200.

In some embodiments of the present invention, as shown in fig. 1-3, the guide block 400 is provided with a support shaft 420, the installation box 100 is provided with a support shaft hole 124, and the support shaft 420 is fitted in the support shaft hole 124, so that the guide block 400 is rotatably installed in the installation box 100.

For example, each supporting shaft hole 124 is divided into two parts and respectively disposed on the box body 110 and the box cover 120, and the box body 110 and the box cover 120 are installed to form the complete supporting shaft hole 124.

In some specific examples of the present invention, as shown in fig. 6, the guide groove 410 is configured as a closed ring structure, for example, may be formed in an inverted heart shape. The slide pin 600 is slidable in one direction along the guide groove 410, and the arrow inside the guide groove 410 in fig. 6 illustrates the one-way sliding direction of the slide pin 600. specifically, the guide groove 410 includes a first ascending section 411, a first descending section 412, a second ascending section 413, and a second descending section 414, which are connected in this order. One end of the first rising section 411 is connected to one end of the first falling section 412, and a distance between the first rising section 411 and the first falling section 412 is gradually increased toward the protruding direction of the rotation pin 200. One end of the second rising section 413 is connected to the other end of the first falling section 412, one end of the second falling section 414 is connected to the other end of the first rising section 411, the other end of the second rising section 413 is connected to the other end of the second falling section 414, and a distance between the second rising section 413 and the second falling section 414 is gradually increased toward the protruding direction of the rotation pin 200. Thus, by providing the guide groove 410 having the above-described shape, the reciprocating sliding of the slide pin 600 in the axial direction thereof can be achieved to drive the slide pin 600 to slide along the guide groove 410 due to the elastic force of the first elastic member, so that the slide pin 600 is kept engaged with the guide groove 410, that is, the expansion and contraction of the rotary pin 200 is restricted by the rocker arm 500, and a push type door opening and closing device is formed, that is, the opening and closing of the door cannot be achieved by applying a pulling force.

For example, when the flap is in the closed position, the sliding pin 600 slides between the second rising section 413 and the second falling section 414, where a V-shaped structure is formed, and the sliding pin 600 is supported against the V-shaped structure and balanced by the first elastic member 700, and cannot slide any more. Only when the flap is pressed, the rotating pin 200 drives the sliding pin 600 to slide toward one side (lower left in fig. 6) of the V-shaped structure through the rocker arm 500 for a short stroke, and then the sliding pin 600 can continue to slide, i.e., reach the flap opening position, under the force of the second elastic member 300. In other words, when a pulling force is applied to the flap when the flap is closed, the sliding pin 600 is stopped by the V-shaped structure and cannot be moved, so that the opening of the flap cannot be achieved.

In some embodiments of the present invention, as shown in fig. 1 and 2, the flap opening and closing device 1 further includes a motor 910 and a locking block 920.

The motor 910 is mounted to the case 110 of the installation case 100.
