Embodiment Construction

[0015] As shown in FIG. 1 , a firmly installed filter lower cover includes a circular lower cover body 1 , and the ring edges of the lower cover body 1 are respectively bent downward to form a snap ring 2 . 1. There is a boss 3 protruding upward in the center, and an annular partition 4 is provided on the upper surface of the lower cover body 1 on the outer side of the boss 3. The boss 3 and the partition 4 have the same height. On the upper surface of the cover body 1 , there are radially integrated reinforcing ribs 5 distributed on the outer side of the partition plate 4 , the boss 3 has external threads, and the partition plate 4 is provided with a positioning groove 6 .

[0016] The lower cover body 1 is made of nylon material.

[0017] The nylon material is obtained by granulating the following raw materials in parts by weight: nylon PA66 70, PA11 10, polytetrafluoroethylene 8, poly-4-methyl-1-pentene 2, silane coupling agent KH-540 1, antioxidant 1035 0.4, anti-ultravio...

Abstract

The invention discloses a firmly-installed filter lower cover. The lower cover comprises a circular lower cover body, and the ring edge parts of the lower cover body are bent downwards to form clamping rings. A boss protruding upwards is arranged in the center of the lower cover body, an annular partition plate is arranged on the upper surface of the lower cover body and located on the outer sideof the boss, the boss and the partition plate are the same in height, radially integrated reinforcing ribs are distributed on the upper surface of the lower cover body and located on the outer side ofthe partition plate, the boss is provided with an external thread, and a positioning groove is formed in the partition plate. The filter lower cover is simple in structure and reasonable in design, the lower cover plate is installed more firmly through the boss, the external thread and the positioning groove in the partition plate, the requirement for sealing performance is met, and practicability is high.

Description

technical field [0001] The invention relates to the technical field of filters, in particular to a firmly installed filter lower cover. Background technique [0002] The engine has three filters for air, oil and fuel, which are generally called "three filters". They are respectively responsible for the filtration of the media in the engine air intake system, lubrication system and combustion system. At present, full-flow filters are widely used, and their important components are filter elements, which are located in a closed space composed of components such as shell, lower cover, sealing cover, sealing ring and mounting base, which requires them to have good sealing performance. . [0003] In order to ensure good sealing performance, the sealing performance of the lower cover and the firmness of installation must be guaranteed. Since the existing lower cover structure has defects and cannot meet the requirements of use, it is necessary to improve its structure. SUMMAR...
