Abstract
Description
Technical Field
[0001] This utility model relates to the field of sealing component technology, specifically to a sealing gasket with a positioning structure. Background Technology
[0002] Gaskets, widely used sealing components in mechanical engineering, are primarily used to seal between connecting surfaces to prevent fluid or gas leakage. Traditional gaskets are typically simple sheet structures, prone to displacement or misalignment during installation, leading to decreased sealing performance. This displacement is particularly pronounced in vibration environments or under high pressure conditions, potentially causing seal failure, affecting equipment operation, and possibly posing safety hazards. Furthermore, existing gasket positioning methods often rely on complex external positioning devices or additional installation steps, increasing assembly difficulty and cost. Therefore, there is an urgent need to design a gasket with a simple structure and reliable positioning to improve sealing performance and installation efficiency. Utility Model Content
[0003] The purpose of this invention is to provide a sealing gasket with a positioning structure to solve the problems of easy displacement and unstable sealing performance of existing sealing gaskets during installation.
[0004] To achieve the above-mentioned utility model objectives, the technical solution provided by this utility model is as follows: a sealing gasket with a positioning structure, comprising a sealing gasket body, wherein a positioning protrusion is provided on at least one side surface of the sealing gasket body, the positioning protrusion is integrally formed with the sealing gasket body, and the height of the positioning protrusion does not exceed one-third of the thickness of the sealing gasket body.
[0005] Furthermore, the positioning protrusions are distributed in a ring around the edge area of the sealing gasket body, and the ring-shaped positioning protrusions are concentrically arranged with the central axis of the sealing gasket body to form a first positioning structure.
[0006] Furthermore, the central region of the sealing gasket body is provided with at least one central positioning protrusion, and the central positioning protrusion and the ring-shaped positioning protrusions form a positioning synergy.
[0007] Furthermore, the cross-sectional shape of the positioning protrusion is trapezoidal or arc-shaped.
[0008] Furthermore, the sealing gasket body is made of rubber, silicone, or polytetrafluoroethylene, and the positioning protrusion and the sealing gasket body are integrally molded from the same material.
[0009] Furthermore, the other side surface of the sealing gasket body is provided with an anti-slip texture, which is distributed in a grid or wavy pattern.
[0010] The advantages of this invention compared to existing technologies are as follows: The integrated positioning protrusion structure enables rapid and accurate alignment of the gasket during installation, avoiding the problem of easy displacement common with traditional gaskets. The synergistic effect of the annular and central positioning protrusions ensures uniform stress distribution on the gasket under pressure, improving sealing performance and stability. The positioning structure is integrally formed with the gasket body, eliminating the need for additional positioning devices or complex installation steps, thus reducing production costs and assembly difficulty. Different materials and positioning protrusion designs can be selected according to different sealing requirements, making it suitable for various working conditions and equipment.

Identical components are represented by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.
[0015] Combined with appendix Figure 1 To be continued Figure 2 A sealing gasket with a positioning structure includes a sealing gasket body 1, wherein at least one side surface of the sealing gasket body 1 is provided with a positioning protrusion 2, the positioning protrusion 2 is integrally formed with the sealing gasket body 1, and the height of the positioning protrusion 2 does not exceed one-third of the thickness of the sealing gasket body.
[0016] Furthermore, the positioning protrusions 2 are distributed in a ring around the edge area of the sealing gasket body, and the ring-shaped positioning protrusions 2 are concentrically arranged with the central axis of the sealing gasket body 1 to form a first positioning structure.
[0017] Furthermore, the central area of the sealing gasket body 1 is provided with at least one central positioning protrusion 3, which forms a positioning synergy with the annularly distributed positioning protrusions 2 to ensure the precise alignment of the sealing gasket during installation.
[0018] Furthermore, the cross-sectional shape of the positioning protrusion 2 is arc-shaped, which ensures the positioning effect while avoiding damage to the contact surface during installation.
[0019] Furthermore, the sealing gasket body 1 is made of rubber, and the positioning protrusion 2 is integrally molded with the sealing gasket body 1 using the same material to ensure the consistency of performance between the positioning structure and the sealing body.
[0020] Furthermore, the other side surface of the sealing gasket body 1 is provided with anti-slip texture 4, which is distributed in a grid or wavy pattern to increase the friction between the sealing gasket and the contact surface and prevent the sealing gasket from sliding during use.
[0021] The specific implementation of this utility model is as follows: During installation, the sealing gasket body 1 is first placed on the sealing surface of the equipment, aligning the positioning protrusion 2 with the corresponding groove or positioning structure on the equipment. Then, appropriate pressure is applied to ensure that the sealing gasket fits tightly against the sealing surface. The central positioning protrusion 3 serves as a preliminary positioning feature, helping operators quickly locate the installation position; the annular positioning protrusion 2 further ensures that the edge of the sealing gasket is aligned with the edge of the sealing surface, improving the sealing effect.
[0022] The anti-slip texture 4 can effectively prevent the gasket from sliding or shifting due to factors such as vibration and pressure changes during use. Especially during equipment operation, the anti-slip texture 4 can maintain the stable position of the gasket and avoid sealing failure caused by gasket displacement.
