Description

Technical Field

[0001] The utility model relates to the field of gasket production, in particular to an anti-deformation gasket. Background Art

[0002] A washer is a mechanical part usually used to connect two non-moving parts. Its main function is to increase friction, prevent fasteners from loosening or locking, and protect the surface of the connected parts from damage. It is generally a flat metal ring used to protect the surface of the connected parts from being scratched by the nut and to disperse the pressure of the nut on the connected parts.

[0003] However, the current gaskets still have some shortcomings. For example, a gasket for preventing oil leakage from an overflow valve with application number 202121145677.6 has not yet fully considered the anti-deformation structure of the gasket. During the use of the gasket, if the anti-deformation structure of the gasket is not fully considered, when the gasket is subjected to excessive force, deformation and damage may occur, which greatly shortens the service life of the gasket. Even a damaged gasket may damage the surface of the workpiece, seriously affecting the use of the gasket by the staff.

[0004] Therefore, it is urgent to improve this shortcoming. The utility model studies and improves the existing structure and shortcomings, and provides an anti-deformation gasket. Utility Model Content

[0014] The utility model provides an anti-deformation gasket, which has the following beneficial effects:

[0015] 1. The utility model is provided with a buffer assembly and a buffer rubber ring. By arranging the buffer assembly between the upper washer and the lower washer, when the washer is used, after the washer is subjected to an external force, the upper washer and the lower washer are constantly approaching each other, so that the first circular block fixedly connected to the bottom of the upper washer and the second circular block fixedly connected to the upper surface of the lower washer are approached to each other. As the first circular block and the second circular block are approached to each other, the end of the telescopic limit rod is limitedly movable inside the hollow rod, so that the telescopic limit rod squeezes the shock-absorbing spring arranged inside the hollow rod, and at the same time, the buffer spring arranged outside the telescopic limit rod is squeezed between the hollow rods. Thereby a certain shock absorption and buffering is performed. In addition, when the upper washer and the lower washer are getting closer, the first fixed plate and the second fixed plate also get closer to each other, thereby squeezing the buffer rubber ring to a certain extent, and utilizing the buffer rubber ring to perform a certain shock absorption and buffering. The improved device utilizes the buffer assembly and the buffer rubber ring to enable the washer to achieve the purpose of buffering and preventing deformation. During the use of the washer, the washer is buffered to avoid deformation and damage caused by excessive force on the washer, and the washer is protected to a certain extent to extend the service life of the washer. At the same time, the damaged washer is prevented from damaging the workpiece surface, making it convenient for the staff to use the washer.

[0016] 2. The utility model is provided with an arc-shaped protruding ring and a snap-fitting ring, by fixing the arc-shaped protruding ring at the bottom of the upper gasket, when the gasket is subjected to a force, the upper gasket and the lower gasket approach each other, so that the arc-shaped protruding ring is gradually snap-fitted and connected with the annular groove provided on the upper surface of the lower gasket, and the first fixing ring welded on the outer edge of the first fixing plate is also gradually snap-fitted and connected with the second fixing ring welded on the outer edge of the second fixing plate, so that the snap-fitting ring fixedly connected at the bottom of the first fixing ring is gradually snap-fitted and connected with the snap-fitting groove provided on the top of the second fixing ring. The improved device utilizes the arc-shaped protruding ring and the snap-fitting ring to prevent the gasket from dislocation. In the process of using the gasket, dislocation of the upper and lower parts of the gasket is avoided, thereby ensuring good performance of the gasket when in use, making it smoother for staff to use the gasket and convenient for staff to use.
