[0008] The utility model is further configured as follows: the interval angles between two adjacent second process holes are equal.

[0009] The utility model is further configured as follows: the gasket body is made of cast iron material.

[0010] In summary, the utility model has the following beneficial effects: the gasket involved in the utility model, by arranging spring pieces for preventing loosening on both sides of the end face of the gasket, the spring piece on the upper end face is used as an anti-loosening connection with the fastener, and the spring piece on the lower end face is used as an anti-loosening connection with the mounting surface.

[0012] In order to enable those skilled in the art to better understand the technical solution of the utility model, the preferred implementation scheme of the utility model is described below in conjunction with specific embodiments, but it should be understood that these descriptions are only for further illustrating the features and advantages of the utility model, rather than limiting the patent requirements of the utility model. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the utility model.

[0013] The utility model is further described below in conjunction with the accompanying drawings and preferred embodiments.

[0014] Example 1

[0015] See also Figure 1 As shown, a gasket involved in this embodiment includes a gasket body 1 in a circular ring shape, a plurality of first process holes 2 close to the inner edge are arranged on the circumference of the gasket body 1, a first elastic piece 3 connected to the hole wall on the left or right side is arranged in the first process hole 2, and the other side of the first elastic piece 3 extends obliquely and extends out of the upper end surface of the gasket body 1; a plurality of second process holes 4 close to the outer edge are arranged on the circumference of the gasket body 1, a second elastic piece 5 connected to the hole wall on the right or left side is arranged in the second process hole 4, and the other side of the second elastic piece 5 extends obliquely and extends out of the lower end surface of the gasket body 1;

[0016] When the left side of the first spring piece 3 is connected to the hole wall of the first process hole 2, the right side of the second spring piece 5 is connected to the hole wall of the second process hole 4; when the right side of the first spring piece 3 is connected to the hole wall of the first process hole 2, the left side of the second spring piece 5 is connected to the hole wall of the second process hole 4.

[0017] Furthermore, the interval angles between two adjacent first process holes 2 are equal; the interval angles between two adjacent second process holes 4 are equal.

[0018] Furthermore, the gasket body 1 is made of cast iron material.

[0019] In this embodiment, the first spring sheet 3 arranged around and close to the inner side protrudes upward and contacts the tightened nut or bolt head. The end face of the nut or the end face of the bolt head contacts the first spring sheet 3 and squeezes it. The squeezing will cause the spring sheet to deform, thereby achieving an elastic locking effect; the second spring sheet 5 arranged around and close to the outer side protrudes downward and contacts the mounting surface. The tightening force squeezes the second spring sheet, which will cause the spring sheet to deform, thereby also achieving an elastic locking effect.
