[0006] Preferably, a steel wire layer shaping block is provided inside the gasket body.

[0007] Preferably, a side strip groove is provided on each side of the oil storage tank.

[0008] Preferably, the edge strip groove has a rectangular structure.

[0009] Preferably, a non-slip bottom pad is provided at the bottom of the gasket body, and the gasket body and the non-slip bottom pad are integrally cast.

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] See Figure 1-Figure 2 A convex spherical gasket for a pressure head includes a gasket body 1, a top gasket ring 2 is provided on the top of the gasket body 1, the top gasket ring 2 surrounds the outside of the spherical crown 3, a bottom gasket ring 4 is provided on the bottom of the gasket body 1, and an oil storage tank 5 is provided between the gasket body 1 and the bottom gasket ring 4.

[0020] See Figure 3A steel wire layer shaping block 7 is provided inside the gasket body 1. This arrangement can increase the overall structure and pressure resistance of the gasket body 1 through the steel wire layer shaping block 7, avoid direct breakage of the gasket body 1 under excessively high pressure, and improve the service life of the gasket body 1.

[0021] See Figure 4 A side strip groove 501 is provided on each side of the oil storage tank 5. This arrangement makes it easy to utilize the effect of air pressure to seal the cooling oil inside the side strip groove 501, store the cooling oil, avoid its leakage, and thus extend the cooling time of the device.

[0022] See Figure 4 The edge strip groove 501 is a rectangular structure. Compared with the arc structure, the rectangular structure has better sealing performance and is less likely to leak cooling oil.

[0023] See Figure 2 The bottom of the gasket body 1 is provided with an anti-slip bottom pad 6, and the gasket body 1 and the anti-slip bottom pad 6 are integrally cast. This arrangement can further increase the friction between the gasket body 1 and the nut through the anti-slip bottom pad 6, thereby improving its stability.

[0024] Working principle: When using this device, the bolt is passed through the spherical crown 3 and fixed to the workpiece. The device is used to provide a stop and stabilize the bolt. During the operation of the device, cooling oil can be accumulated in the oil storage tank 5 to accelerate the heat dissipation efficiency of the gasket body 1. At the same time, the top gasket 2 and the bottom gasket 4 can provide end sealing protection for the oil storage tank 5 to reduce oil leakage. At the same time, the oil storage tank 5, as a special-shaped groove, can also increase the contact area with the air, thereby further improving the heat dissipation effect.

[0025] In the description of this specification, the terms "connect", "install", "fix", "set", etc. are all understood in a broad sense. For example, "connection" can be a fixed connection or an indirect connection through an intermediate component without affecting the relationship between the components and the technical effect, or it can be an integral connection or a partial connection. As in this example, for those skilled in the art, the specific meanings of the above terms in this utility model or the utility model can be understood according to the specific circumstances. In this utility model, the directions or positional relationships indicated by the terms "upper", "lower", "left", "right", "front", "back", "top", "bottom", "inside", "outside", "middle", "vertical", "horizontal", "transverse", "longitudinal", etc. are based on the directions or positional relationships shown in the accompanying drawings.
