[0002] The materials of bolt gaskets are generally 65MN spring steel, 70# carbon steel, 3Cr13, stainless steel materials SUS304, SUS316, and phosphor bronze materials. The purpose is to increase the contact area, reduce pressure, prevent bolts from loosening, and improve service life. It is designed to protect parts and bolts.

[0003] Common bolt gaskets generally have a relatively simple structure and are supported by materials such as engineering plastics or rubber. Due to the lack of other structures, their toughness is relatively low and they are prone to cracking. In the light case, users need to replace them irregularly, which is rather cumbersome. In the heavy case, it will cause damage to the mechanical structure and even lead to safety accidents. Therefore, it is important to prevent the low toughness of bolts, so a high-toughness gasket needs to be provided. Summary of the Invention

[0004] Aiming at the defects in the prior art, the utility model provides a high-toughness gasket. The device adds multiple layers of materials to make the gasket play roles in anti-deformation, waterproof, high-temperature resistance, and compression resistance, etc., so as to improve the toughness of the gasket. At the same time, in order to prevent the bolt from falling off, a limiting block is added. Since the second moving block can move according to the use of the bolt and the second moving block itself has a bolt thread hole device, when the bolt is in use, the second moving block can be tightly connected with the bolt, reducing the possibility of the strengthened bolt falling off.

[0005] Preferably, a high-toughness gasket includes a housing, and a through groove is opened in the middle at the upper end of the housing;

[0006] Four transverse grooves are opened around the through groove. On one side above the inner top surface of each of the four transverse grooves, a vertical groove is opened. On one side of each of the four vertical grooves, a limiting groove is opened. A limiting block is slidably arranged inside each of the four limiting grooves. A push block is fixedly arranged on one side of each of the four limiting blocks. A plurality of second one-way teeth are fixedly arranged on the inner bottom surface of each of the four transverse grooves. A first moving block is arranged on the inner top surface of each of the four transverse grooves. A plurality of first one-way teeth are fixedly arranged on the lower end surface of each of the four first moving blocks. A second moving block is fixedly arranged on the side of each of the four first moving blocks away from the push block;

[0007] The housing includes two rubber layers. A waterproof layer is fixedly arranged inside each of the two rubber layers. A metal layer is fixedly arranged at the upper bottom end of the two waterproof layers. A high-temperature resistant layer is fixedly arranged at the bottom end of the metal layer. A compression resistant layer is fixedly arranged at the bottom end of the high-temperature resistant layer.

[0008] Preferably, the four pushing blocks are slidably arranged inside the vertical groove, and the four first moving blocks are slidably arranged inside the horizontal groove.

[0009] Preferably, an annular groove is formed in the middle of the whole body of the housing, and the bottom end of the compression layer is fixedly arranged with the upper end of the waterproof layer.

[0010] Preferably, threaded holes are formed on one side of each of the four second moving blocks, and one side of each of the four second moving blocks is slidably arranged inside the through groove.

[0011] Preferably, one side of each of the four first moving blocks is slidably arranged inside the through groove, and the four second moving blocks are slidably arranged inside the horizontal groove.

[0012] Preferably, the high-temperature resistant layer is made of graphite material, and the metal layer is made of stainless steel material.

[0013] The beneficial effects of the present utility model are embodied in:

[0014] A highly tough gasket proposed by the present utility model, by providing a rubber layer on the outermost surface of the gasket, can make the gasket body have better corrosion resistance and anti-deformation. The high-temperature resistant layer is provided to improve the high-temperature resistance performance of the metal surface, the waterproof layer is provided to improve the waterproof effect of this gasket, and the compression layer is provided to facilitate improving the compression resistance performance of this gasket.

[0015] A highly tough gasket proposed by the present utility model, multiple grooves are arranged inside this gasket to facilitate the vertical movement of the four pushing blocks by the bolt during use. When the four pushing blocks move downward, the four first moving blocks move horizontally, and one side of the four second moving blocks moves to the through groove. Since threaded holes are formed on one side of each of the four second moving blocks, when one side of the four second moving blocks moves to the inside of the through groove, the bolt will be clamped, reducing the possibility of the bolt sliding, and thus reducing the possibility of the bolt falling off due to sliding.

The limit block 6 controls the maximum distance of the push block 2. When the push block 2 reaches the bottom surface, the first moving block 3 moves horizontally inside the horizontal groove 11 due to the movement of the push block 2. The second moving block 5 enters the inside of the through groove 7 due to the movement of the first moving block 3. Since a bolt thread hole is provided on one side of the second moving block 5, when the second moving block 5 moves into the through groove 7, it is tightly connected to the bolt, thereby reducing the possibility of the bolt falling off due to sliding. The rubber layer 105, waterproof layer 101, compressive layer 104, high-temperature resistant layer 103, and metal layer 102 are provided inside the housing 1, which improves the toughness of this gasket and also extends the service life of this gasket.
