Abstract

The invention discloses a press-fit cover plate in an air cleaner, the press-fit cover plate comprises a press-formed disc-shaped plate body, and is characterized in that: the outer edge of the disc-shaped plate body is provided with a downward inward folded outer flange, two downwardly-projecting annular bosses are arranged on the disc-shaped plate body on the inner side of the outer flange, transition surfaces between the annular bosses are inclined surfaces, and connecting ribs are arranged between the inclined surfaces. The press-fit cover plate has reasonable structural design, high mold-making efficiency, convenient installation and fixation, good stability, and long service life through the structural design of a wear-resistant layer.

Description

technical field [0001] The invention relates to a component in an air filter, in particular to a press-fit cover plate in the air filter. Background technique [0002] The filter screw is made by extrusion through a die. The so-called mold is a tool used to shape objects. This tool is composed of various parts, and different molds are composed of different parts. It mainly realizes the processing of the shape of the article through the change of the physical state of the formed material. [0003] The existing press-fit cover plate of the filter has the problems of simple structure, low molding efficiency, inconvenient installation and fixation, poor stability and the like. Contents of the invention [0004] The purpose of the present invention is to make up for the deficiencies of the prior art, and to provide a press-fit cover plate in an air filter, which solves the problem of simple structure of the press-fit cover plate of the filter, low molding efficiency, and inco...
