There are two extrusion assemblies, and the two extrusion assemblies are symmetrically arranged with each other;

It should be noted here that: the two mutually symmetrically arranged extrusion components provide a better guiding and extrusion effect for the sliding plate 202.

A limiting assembly for limiting the rotation rod 303 is provided in the driving groove 301, and the limiting assembly includes an L-shaped plate 501 fixedly connected to the side wall of the driving groove 301, and a T-shaped limiting rod 502 is slidably connected to the L-shaped plate 501.

It should be noted here that: through the setting of the pushing component, under the interaction force between the rounded corner on the T-shaped limit rod 502 and the limit hole 503, the T-shaped limit rod 502 will be pushed to move away from the rotating rod 303. When the rotation of the driving disk 305 is stopped, under the elastic force of the second spring 6, the T-shaped limit rod 502 will be pushed to match the limit hole 503 again, thereby achieving the limitation of the rotating rod 303.

Working principle: When installing the cover 102, place the cover 102 in the frame bracket 101, and then rotate the driving disk 305 to drive the driving block 304 at one end of the rotating rod 303 to rotate. When the driving block 304 and the two driving plates 302 are against each other, the sliding plates 202 at one end of the two driving plates 302 will be pushed away from each other under the mutual force. In the process of the two sliding plates 202 moving away from each other, the first spring 403 will be compressed, so that the first spring 403 is deformed by force to form an elastic force.

When the two sliding plates 202 move away from each other, the mounting plates 203 are synchronously driven to retract into the mounting grooves 201. After the mounting plates 203 are completely retracted into the mounting grooves 201, the cover 102 is pushed into the frame-shaped bracket 101. After the cover 102 enters the frame-shaped bracket 101, the rotation of the driving disk 305 is released. At this time, under the elastic force of the first spring 403, the mounting plates 203 located on both sides of the cover 102 are pushed to move toward each other and enter the mounting holes 204. Therefore, under the pressing action of the mounting plates 203, the cover 102 is installed in the frame-shaped bracket 101.

During a long period of operation, a layer of dirt will adhere to the surface of the grid-type air inlet. In order to improve the convenience and cleanliness of cleaning the grid-type air inlet, it is necessary to remove the cover 102 from the frame bracket 101. When removing the cover 102, rotate the drive disk 305, and through transmission, drive the mounting plates 203 located on both sides of the cover 102 to move away from each other, thereby releasing the installation of the cover 102. At this time, the cover 102 can be removed from the frame bracket 101, rinsed with running water or cleaned with a brush. By detachably connecting the cover 102 to the frame bracket 101, the convenience and cleanliness of cleaning the grid-type air inlet are improved.
