Air filter shell clamping structure

Abstract

The invention discloses an air filter shell clamping structure. The air filter shell clamping structure comprises a top shell and a bottom shell, wherein the front face of the top shell is movably connected with a main rubber strip through two screwing blocks; two secondary rubber clamping blocks are fixedly connected to the positions, located on the two sides of the main rubber strip, of the front face of the top shell; clamping grooves are formed in the two secondary rubber clamping blocks; and a secondary rubber strip is clamped between the two secondary rubber clamping blocks. According to the air filter shell clamping structure, filter paper is stably fixed by rotating the screwing blocks and the secondary rubber clamping blocks and cannot fall off in the running process of an automobile, and normal use of an air filter is effectively guaranteed; and meanwhile, clamping blocks and clamping grooves are connected in a clamped manner, clamping rods of the top shell are clamped through the clamping blocks, and therefore two shells of the filter are firmly connected and cannot be separated due to vibration.

Description

technical field [0001] The invention relates to an air filter, in particular to a clamping structure of an air filter housing. Background technique [0002] The car air filter is mainly responsible for removing particulate impurities in the air. When the piston machine (internal combustion engine, reciprocating compressor, etc.) is working, if the inhaled air contains dust and other impurities, it will aggravate the wear of the parts, so an air filter must be installed. The air filter consists of two parts, the filter element and the housing. The main requirements of the air filter are high filtration efficiency, low flow resistance, and continuous use for a long time without maintenance. [0003] When the air filter is used in production, it is necessary to paste several strips on the top to fix the position of the filter paper. However, most of the existing strips on the market are only fixed by sticking. It is easy to cause the rubber strip to fall off, making it impos...

Problems solved by technology

[0003] When the air filter is used in production, it is necessary to paste several strips on the top to fix the position of the filter paper. However, most of the existing strips on the market are only fixed by sticking. It is easy to cause the rubber strip to fall off, making it impossible to fix the filter paper, resulting in the filter not being able to filter normally. At the same time, the filter shell also needs a more stable clamping device to prevent the shell from being separated due to vibration.
