Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-4, the present invention provides a technical solution: a coarse filter frame connection counter sink comprises top plates 1, the top plates 1 are provided with two groups with the same structure size, two groups of side plates 3 are arranged between the two groups of top plates 1, the outer walls of one sides, close to each other, of the two groups of top plates 1 are provided with grooves, the outer walls of the side plates 3 are attached to the inner walls of the grooves, the top ends and the bottom ends of the two groups of side plates 3 can be covered by the two groups of top plates 1, so that the side plates 3 cannot move out from the space between the two groups of top plates 1, the outer walls of the left side and the right side of the top plates 1 are provided with counter sinks 2, the counter sinks 2 are sunken towards the inner parts of the top plates 1, the vertical section width of the counter sinks 2 is gradually reduced from outside to inside, rivets are inserted into the counter sinks 2, the top plates 1 are connected with the side plates 3, the rivets are arranged in the counter sinks 2, so that the rivets cannot be, the one end that the left and right sides rivet is close to each other and one side wall connection that two sets of curb plates 3 kept away from each other are provided with the filter core between two sets of roof 1, and the filter core is located between two sets of curb plates 3, and filter core fixed mounting is between roof 1 and curb plate 3.

The outer walls of the upper side and the lower side of the side plate 3 are respectively provided with a connecting block 4, the connecting blocks 4 are fixedly connected with the side plate 3, a connecting groove 5 is formed in the contact part of the top plate 1 and the side plate 3, one end, far away from the side plate 3, of the connecting block 4 is inserted into an inner cavity of the connecting groove 5, the inner wall, far away from the connecting groove 5, of the left side and the right side is respectively provided with a limiting groove 6, the outer wall, far away from the connecting block 4, of the left side and the right side is respectively provided with a limiting block 7, the limiting blocks 7 are fixedly connected with the connecting blocks 4, the limiting blocks 7 are located in the inner cavities of the limiting grooves 6, the connecting blocks 4 are inserted into the connecting grooves 5, the side plate 3 is moved, the limiting;
