Further, the intermediate lever 310 is coupled to the first gear, and the intermediate lever 310 is coupled to the second gear via a coupling.

The second moving member 230 includes a second connecting portion 231 and a second guiding engaging portion 234. The second connection portion 231 and the second guide engagement portion 234 are provided in the same manner as the first connection portion 131 and the first guide engagement portion 134.

The second bracket 232 is disposed in the same manner as the first bracket 132. One end of the second bracket 232 is fixedly connected with the door panel 500, and the other end of the second bracket 232 is rotatably connected with the second connecting portion 231.

The second guide member 250 is a second linear rail 252, and the second linear rail 252 is disposed in the guide hole of the second connecting seat 210.

The second moving member 230, the second connecting seat 210, the second bracket 232, and the second guide member 250 are disposed in the same manner as the first moving member 130, the first connecting seat 110, the first bracket 132, and the second guide member 250.

Specifically, when the door panel 500 and the wall 400 are in the closed state during use, the door panel 500 is pressed, the door panel 500 moves towards the direction close to the wall 400 to drive the first connecting portion 131, the first connecting portion 131 and the first guiding and matching portion 134 on the first connecting portion 131 both move towards the direction close to the wall 400, the first guiding and matching portion 134 is a first optical axis, the first optical axis penetrates out of the first linear slide rail 152 on the first guiding hole 112, the door panel 500 is unlocked from the wall 400, at this time, the door panel 500 pops up, under the action of the elastic element 160, the first guiding element 150 and the first guiding and matching portion 134, the door panel 500 moves horizontally towards the direction far away from the wall 400, the first optical axis is just located in the first linear slide rail 152 on the first guiding hole 112, and the side wall close to the wall 400 of the first connecting portion 131 is abutted against the first connecting seat 110, at this time, the door panel 500 can be turned 180 degrees to be opened.

After the door panel 500 is opened, the door panel 500 is turned to press the door panel 500 toward the wall 400, so that the door panel 500 and the wall 400 can be locked, thereby closing the door panel 500.

The above examples illustrate only a few embodiments of the utility model, which are described in detail and are not to be construed as limiting the scope of the claims. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the utility model, which are all within the scope of the utility model. Accordingly, the scope of protection of the present utility model is to be determined by the appended claims.
