Description

Technical Field

[0001] The utility model relates to the technical field of sealing products, in particular to a sealing gasket with a positioning structure. Background Art

[0002] Sealing gaskets are used as sealing components in machinery, equipment, pipelines, and anywhere fluids are present. They are used internally and externally to provide a seal. Sealing gaskets are made from metal or non-metallic plates through processes such as cutting, stamping, or shearing. Sealing gaskets can be divided into metal and non-metallic types based on their material. Metal gaskets include copper, stainless steel, iron, and aluminum gaskets, while non-metallic types include asbestos, non-asbestos, paper, and rubber gaskets.

[0003] For example, Chinese patent CN216843069U discloses a sealing gasket with a positioning structure, which includes a metal coil sheet, a lower guard plate, and an upper guard plate. The upper guard plate is welded to the top of the metal coil sheet, and the lower guard plate is welded to the bottom of the metal coil sheet. The outer sides of the lower guard plate and the upper guard plate are covered with protective rubber sleeves. It has a positioning structure, which is convenient for installation and positioning, and has high strength and is not easy to deform after long-term use. However, the above-mentioned sealing gasket with a positioning structure is an integral design. When any part is damaged, the entire sealing gasket needs to be replaced, which increases the cost and complexity of maintenance. In the case of damage to different parts, a large number of spare integral sealing gaskets need to be stored, which takes up storage space and increases inventory costs.

[0004] Currently, no effective solutions have been proposed for the problems in related technologies. Utility Model Content

[0005] In view of the problems in the related art, the present invention proposes a sealing gasket with a positioning structure to overcome the above technical problems existing in the existing related art.

[0006] To this end, the specific technical solutions adopted in this utility model are as follows:

[0007] A sealing gasket with a positioning structure includes a first sealing body, a second sealing body is arranged on one side of the first sealing body, and the first sealing body and the second sealing body are connected by a fixing rod; the cross sections of the first sealing body and the second sealing body are both semi-annular structures.

[0008] Furthermore, in order to improve the sealing performance of the sealing gasket, the trapezoidal structure of the expansion groove helps to maintain the shape of the sealing gasket. When subjected to external pressure, it helps to maintain the basic shape of the sealing body and prevent sealing failure caused by excessive deformation. The anti-slip protrusion increases the friction between the sealing body and the contact surface, which helps to prevent the sealing body from sliding or moving during use. The chamber and the spring enable the sealing gasket to produce elastic deformation through the spring when under pressure, so as to better adapt to the sealing surface. The outer sides of the first sealing body and the second sealing body are both provided with expansion grooves, and the cross-section of the expansion groove is a trapezoidal structure. The top and bottom ends of the first sealing body and the second sealing body are both provided with a number of anti-slip protrusions, and the top and bottom ends of the first sealing body and the second sealing body are both embedded with support plates; the middle part of the first sealing body and the second sealing body is provided with a number of chambers, and the inside of the chamber is provided with a spring; the inner walls of the first sealing body and the second sealing body are both provided with a number of sealing strips, and the anti-slip protrusions are hemispherical structures.

[0009] Furthermore, in order to achieve convenient installation between the first sealing body and the second sealing body, a positioning structure is formed by a positioning groove and a positioning block to ensure accurate docking between the sealing bodies and improve the accuracy of installation. Positioning grooves are provided at both ends of one side of the first sealing body, and the side walls of the positioning grooves are provided with through holes that pass through the telescopic grooves; positioning blocks that cooperate with the positioning grooves are provided at both ends of one side of the second sealing body, and the cross-section of the positioning blocks is a square structure; a threaded hole is provided on one side wall of the positioning block.

[0010] Furthermore, in order to achieve fixed installation between the first sealing body and the second sealing body and ensure the stability of the sealing gasket, a thread matching the threaded hole is provided on the outer side of one end of the fixing rod, and a groove is provided on the side wall of the other end of the fixing rod, and the cross-section of the groove is a cross-shaped structure.

[0011] The beneficial effects of the utility model are:

[0012] 1. The utility model has a reasonable and reliable structure. The first sealing body and the second sealing body form a combined sealing gasket. When any one component is damaged or requires maintenance, there is no need to replace the entire sealing gasket, which reduces maintenance costs and simplifies the maintenance process. At the same time, when replacing, only the damaged part needs to be replaced, which further saves costs and reduces the need for inventory spare parts.

[0013] 2. By setting the expansion groove, anti-slip protrusion and spring, the sealing performance of the sealing gasket is improved. The trapezoidal structure of the expansion groove helps to maintain the shape of the sealing gasket. When subjected to external pressure, it helps to maintain the basic shape of the sealing body and prevent sealing failure caused by excessive deformation. The anti-slip protrusion increases the friction between the sealing body and the contact surface, which helps to prevent the sealing body from sliding or moving during use. The chamber and spring enable the sealing gasket to produce elastic deformation through the spring when under pressure, thereby better adapting to the sealing surface.

[0014] 3. By providing the positioning groove and the positioning block, convenient installation between the first sealing body and the second sealing body is achieved. The positioning groove and the positioning block constitute a positioning structure, which ensures accurate docking between the sealing bodies and improves the accuracy of installation.
