Embodiment Construction

[0012] In order to further understand the content, features and effects of the present invention, the following embodiments are given as examples, and detailed descriptions are as follows with accompanying drawings:

[0013] See Figure 1-Figure 2 , A spring-expandable seal, comprising a cylindrical body 1 having an axial through hole 2 in the center of the cylindrical body 1. The two ends of the cylindrical body 1 extend outward to form an upper sealing flange portion 3 and a lower sealing flange portion 4. There is a circumferential gap 5 between the upper sealing flange portion 3 and the lower sealing flange portion 4. The columnar body 1, the upper sealing flange part 3 and the lower sealing flange part 4 are integrally constructed and are processed by neoprene rubber, which is resistant to high temperature and aging.

[0014] A plurality of upper slot holes 7 evenly distributed around the central circumference of the cylindrical body 1 are provided on the lower surface of th...

Abstract

The invention relates to a spring tension type sealing piece which is characterized in that the spring tension type sealing piece comprises a cylindrical body, the center of the cylindrical body is provided with an axial through hole, the two ends of the cylindrical body extend outwards to form an upper sealing flange portion and a lower sealing flange portion, a round seam is formed between the upper sealing flange portion and the lower sealing flange portion, the lower face of the upper sealing flange portion is provided with a plurality of upper groove holes evenly distributed in the central peripheral direction of the cylindrical body. The upper face of the lower sealing flange portion is provided with a plurality of lower groove holes evenly distributed in the central peripheral direction of the cylindrical body. The upper groove holes correspond to the lower groove holes one by one. Springs are arranged between the upper groove holes and the correspondingly opposite lower groove holes. The upper ends of the springs are located in the upper groove bodies. The lower ends of the springs are located in the lower groove bodies. According to the spring tension type sealing piece, the sealing function of gaskets can be maintained under the action of the springs, and the sealing effect is good.

Description

Technical field [0001] The invention belongs to the technical field of technical seals, and particularly relates to a spring-expanded seal. Background technique [0002] The working environment of automotive motors is generally dusty and often exposed to water. In severe cases, the motor will short-circuit or fail. High-power motors are particularly important. Therefore, the motor is required to have a good sealing effect to prevent dust and other substances from entering the motor and affecting the work, especially waterproof measures. When an electric vehicle is traveling, bumps are inevitable. In a long-term bumpy working environment, the fasteners used to fix the sealing gasket are easy to loosen, so that the seal between the gasket and the motor and the junction box fails. Failure due to water ingress. Therefore, it is necessary to design a sealing gasket with self-sealing function and good sealing effect. Summary of the invention [0003] In order to solve the technical p...
