Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be described below with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1, the rivet-less filter 10 of the present invention includes a filter element 1 and a frame 2 installed around the filter element, wherein the frame 2 is used for accommodating the edge of the filter element 1. The frame 2 comprises a first frame 21 and a second frame 22 adjacent to the first frame 21, the filter element 1 comprises a long edge and a short edge which are oppositely arranged, the first frame 21 is arranged on the two long edges, and the second frame 22 is arranged on the two short edges.
As shown in fig. 2, the first frame 21 includes a first side wall 211 and two first cross arms 212 oppositely disposed, the first side wall 211 and the two first cross arms 212 form a first receiving groove 210, and the first receiving groove 210 extends longitudinally and receives one end of the filter cartridge 1.
The first side wall 211 is provided at both ends thereof with a plurality of fixing pieces 214, in this embodiment, the fixing pieces 214 are trapezoidal columns, the height of the trapezoidal column is 13mm, the length of the long side of the cross section of the trapezoidal column is 13mm, and the length of the short side of the cross section of the trapezoidal column is 6 mm.
As shown in fig. 3, the second frame 22 includes a second side wall 221 and two second arms 222 disposed opposite to each other, and both ends of the second arms 222 are received in the notches 213. The second side wall 221 and the second horizontal arm 222 form a second receiving groove 220, and the second receiving groove 220 extends longitudinally and receives the other end of the filter cartridge 1. The end portions of the filter element 1 accommodated in the first accommodating groove 210 and the second accommodating groove 220 are disposed adjacent to each other.
The second frame 22 has a plurality of openings 223 at both ends thereof, and in particular, the plurality of openings 223 are opposite to the fixing pieces 214 and have a shape matching therewith. When the first frame 21 and the second frame 22 are mounted, the first sidewall 211 is bent such that the fixing piece 214 is inserted into the opening 223, thereby connecting the first frame 21 and the second frame 22 opposite to each other.
