[0025] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the present utility model will be briefly introduced below in conjunction with the accompanying drawings and descriptions of the embodiments or the prior art. Obviously, the following description of the structure of the accompanying drawings is only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort. It should be noted that the description of these embodiments is used to help understand this utility model, but does not constitute a limitation on this utility model.

[0026] Example:

[0027] like Figures 1 to 6 As shown, this embodiment provides a bolt fastening kit to prevent loosening, including a bolt 1, a nut 3, a first washer 2, and a first cap 4. The bolt 1 includes a nut 101 and a threaded rod 102, and the nut 3 and the first washer 2 are located on the threaded rod 102.

[0028] In use, the fastening object is located between the nut 101 and the first gasket 2, the first gasket 2 is located between the fastening object and the nut 3, and when the nut 3 is tightened, the first buckle cap 4 buckles on the first gasket 2 and the nut 3 to tightly wrap the first gasket 2 and the nut 3.

[0029] The end surface of the first gasket 2 in contact with the fastening object is provided with first radial teeth 201, and the outer periphery of the first gasket 2 is provided with vertical outer teeth 203. The first buckle cap 4 is provided with a through hole, the lower end of the through hole is provided with vertical inner teeth 401 matched with the outer teeth 203 of the first gasket 2, and the upper end of the through hole of the first buckle cap 4 is a hexagonal hole 402. The nut 3 is a hexagonal nut 3, and the size of the hexagonal hole 402 is matched with the nut 3, so that when the first buckle cap 4 buckles on the first gasket 2 and the nut 3, the through hole of the first buckle cap 4 is matched with the first gasket 2 and the nut 3 to form a tight wrapping. Through the above embodiment, by providing radial teeth on the contact surface of the nut 101 and the first gasket 2 which can contact the fastening object, after fastening, the fastening effect can be better. On the other hand, the combination of the first gasket 2 and the nut 3 is also a means to improve the fastening effect. Further, the first buckle cap 4 matched with the first gasket 2 and the nut 3 is used, the vertical teeth are engaged, and the hexagonal hole 402 is matched, so that the first gasket 2 and the nut 3 do not rotate relative to each other, further improving the fastening effect. The nut used in this embodiment is a common hexagonal nut, and in specific implementation, the nut can also be a quadrangular nut, and correspondingly, the upper end of the through hole of the first buckle cap 4 is designed as a quadrangular hole 402 to adapt to the quadrangular nut.

[0030] In a possible implementation, as shown in Figure 3 The first buckle cap 4 and the top 101 of the nut are arc-shaped.

[0031] In a possible implementation, as shown in Figure 1 , Figure 2 The side of the first gasket 2 close to the nut 3 is provided with a groove 202. In specific implementation, the groove 202 is a hexagonal groove matched with the nut 3. Correspondingly, the nut used in this embodiment is a common hexagonal nut, and in specific implementation, the nut can also be a quadrangular nut, and correspondingly, the groove 202 is designed as a quadrangular groove matched with the nut 3 to adapt to the quadrangular nut.

[0032] In specific implementation, as shown in Figure 3 The groove 202 can also be arc-shaped, and the end of the nut 3 close to the first gasket 2 is provided with an arc-shaped protrusion matched with the groove 202.

[0033] In a possible implementation, when the nut 3 is screwed, part of the nut 3 is located in the groove 202 of the first washer 2. In specific operation, when the nut 3 is combined with the first washer 2 and rotated in the screwing direction, the first washer 2 rotates together with the nut 3 until the nut 3 is screwed, and only the end of the nut 3 close to the first washer 2 is located in the groove 202, which does not affect the actual operation.

[0034] In a possible implementation, the diameter of the first washer 2 is greater than the distance between two symmetrical corners of the outer periphery of the nut 3. The two symmetrical corners are symmetrical with respect to the center line of the screw hole of the nut 3. The diameter of the first washer 2 refers to the distance between the top points of the recesses between two adjacent vertical teeth on the outer periphery of the first washer 2, which are located on the circumference, and the diameter of the circle with the center line of the first washer 2 as the center.

[0035] In a possible implementation, the first radial tooth 201 is inclined, and the inclination direction of the first radial tooth 201 is opposite to the screwing direction of the nut 3. By designing the first radial tooth 201 to be inclined and the inclination direction of the first radial tooth 201 to be opposite to the screwing direction of the nut 3, when the nut 3 is screwed and the nut 3 and the first washer are retracted, the radial tooth can generate greater resistance.

[0036] In a possible implementation, as shown in Figure 2 a second washer 5 is arranged between the fastening object and the nut 101.

[0037] In a possible implementation, as shown in Figure 2 a second radial tooth 501 is arranged on the end surface of the second washer 5 in contact with the fastening object. By arranging the second radial tooth 501 on the end surface of the second washer 5 in contact with the fastening object, the resistance to retraction of the nut 101 is increased. In specific implementation, a second buckle 6 is arranged on the periphery of the nut 101 and the second washer 5, so that the second washer 5 and the nut 101 are relatively rotated.

[0038] In a possible implementation, the second radial tooth 501 is inclined, and the inclination direction of the second radial tooth 501 is the same as the screwing direction of the nut 3. By arranging the second radial tooth 501 to be inclined and the inclination direction of the first radial tooth 201 to be the same as the screwing direction of the nut 3, the resistance to retraction of the nut 101 is further increased.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present application and is not used to limit the protection scope of the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
