Description

Technical Field

[0001] This utility model belongs to the field of electromechanical components technology, and more specifically, it relates to a reinforcing structure for the main body of the rear shell. Background Technology

[0002] Fluorine-lined back covers are components that cover the inner surface of a metal or other substrate with fluoroplastics. Thanks to the excellent corrosion resistance and high temperature resistance of fluoroplastics, they can resist the erosion of strong corrosive media such as strong acids and strong alkalis. They are mainly used in chemical, petroleum, and pharmaceutical industries to protect equipment, extend its service life, and ensure safety. Some also have a sealing function.

[0003] Based on the above, the traditional back cover and back cover reinforcement cover are two products assembled together. There will be a gap between the two products. If the fit is not good, the back cover may be deformed or damaged. The traditional back cover reinforcement cover is made of a single material and cannot effectively enhance the overall strength of the back cover. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a reinforcing structure for the back cover body, which solves the problems mentioned in the background art that there is a gap between the traditional back cover and the back cover reinforcing cover, and the back cover may be deformed or damaged if not properly fitted. The traditional back cover reinforcing cover is made of a single material and cannot effectively enhance the overall strength of the back cover.

[0005] The purpose and effect of the reinforcing structure of the rear shell body of this utility model are achieved by the following specific technical means:

[0006] A reinforcing structure for a rear shell body includes a rear cover, the middle of which is a cover-like structure protruding upwards, and a shaft cylinder structure in the middle of the rear cover, with a slot on the outer side of the top of the shaft cylinder structure; a reinforcing cover, the sides of which can fit against the outside of the rear cover; a protruding circular surrounding structure integrally provided in the middle of the inner side of the top of the reinforcing cover, the circular surrounding structure being able to fit against the outer side of the top of the shaft cylinder structure of the rear cover; the top of the rear cover does not contact the reinforcing cover, and a stainless steel reinforcing member is installed in the gap between the reinforcing cover and the rear cover; an assembly shaft is fixedly provided in the shaft cylinder structure of the rear cover by interference fit.

[0007] Furthermore, the bottom edge of the rear cover has an upward-curving flange structure.

[0008] Furthermore, the bottom center of the back cover is integrally provided with a buckle for assembly, and the inner side of the buckle has an extended slot structure.

[0009] Furthermore, positioning grooves are provided at the middle of both the upper and lower ends of the assembly shaft.

[0010] Furthermore, the rear cover's cylindrical structure is integrally provided with a docking structure that matches the positioning groove of the assembly shaft.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] Optimized structural fit reduces defects: The new structure, through reasonable design, allows the back cover and the reinforcing cover to fit tightly, avoiding the gap problem in the assembly of the two in the traditional structure. This reduces the occurrence of deformation, tearing and other problems caused by poor fit of the back cover, and improves the overall assembly stability.

[0013] Enhanced overall strength and stable operation: A stainless steel reinforcing component matching the arc-shaped design of the rear cover is added between the rear cover and the reinforcing cover. This effectively solves the strength and concentricity problems of the shaft caused by the centrifugal force of the pump, significantly enhances the overall strength of the rear cover, and can better cope with the action of various forces during use, ensuring stable operation of the equipment.

[0014] Flexible material selection to meet diverse needs: The back cover can be made of various materials according to different requirements such as liquid, temperature, and cleanliness, and the reinforcing cover can also be made of various reinforcing materials according to environmental and temperature conditions, so that the reinforcement structure can adapt to different application scenarios in multiple industries such as chemical, petroleum, and pharmaceutical, thereby improving the applicability and practicality of the structure.
