[0006] A nut, comprising a nut body, an elastic washer is fixedly connected to the bottom surface of the nut body, an elastic leather ring is fixedly connected to the side wall of the elastic washer close to the nut body, and a groove is opened at the center of each side wall of the nut body.

[0007] As a preferred technical solution of the present utility model, anti-slip blocks are fixedly connected to the bottom surface of the elastic washer, and a plurality of anti-slip blocks are evenly distributed.

[0008] As a preferred technical solution of the present utility model, the cross section of the anti-slip block is trapezoidal, and the top surface area of the anti-slip block is larger than its bottom surface area.

[0009] As a preferred technical solution of the present utility model, the cross section of the elastic leather ring is L-shaped, and the vertical side of the elastic leather ring is fixedly connected to the inner side wall of the elastic washer.

[0010] As a preferred technical solution of the present utility model, the elastic leather ring is hollow.

[0011] As a preferred technical solution of the present utility model, the groove is regular hexagon-shaped.

[0012] The embodiment of the utility model provides a nut, which has the following beneficial effects:

[0013] 1. In the utility model, the nut body and the elastic washer are fixedly connected together. When installing the nut, the situation of missing installation of the elastic washer can be effectively avoided, and the installation efficiency of the nut can be effectively improved. Moreover, through the anti-slip blocks and the elastic rubber rings arranged on the elastic washer, the stability between the nut and the parts is improved by using the anti-slip blocks, and through the expansion of the elastic rubber rings, the elastic rubber rings are tightly attached to the side wall of the bolt, further improving the reliability of the nut installation, and the use effect is good;

[0014] 2. In the utility model, through the arrangement of the groove, when installing the nut body, when the internal space of the equipment is small and not conducive to tool operation, a suitable tool can be inserted into the groove, and at this time, the nut body can be conveniently rotated, facilitating the installation operation of the nut.

[0022] The following is a description of the preferred embodiments of the utility model with reference to the drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the utility model and are not used to limit the utility model.

[0023] Embodiment: As Figures 1-5As shown in the figure, a nut includes a nut body 1, and an elastic washer 2 is fixedly connected to the bottom surface of the nut body 1. The elastic washer 2 is fixedly connected to the nut body 1, which facilitates the installation operation of the nut.

[0024] Among them, anti-slip blocks 5 are fixedly connected to the bottom surface of the elastic washer 2. A number of anti-slip blocks 5 are evenly distributed. The cross-section of the anti-slip block 5 is trapezoidal, and the top surface area of the anti-slip block 5 is larger than its bottom surface area, which further improves the installation reliability of the nut body 1.

[0025] An elastic leather ring 3 is fixedly connected to the side wall of the elastic washer 2 close to the nut body 1. The cross-section of the elastic leather ring 3 is L-shaped. The vertical side of the elastic leather ring 3 is fixedly connected to the inner side wall of the elastic washer 2. The elastic leather ring 3 is hollow. The expansion of the elastic leather ring 3 can improve the reliability between the nut body 1 and the bolt.

[0026] A groove 4 is provided at the center of each side wall of the nut body 1, which facilitates the rotational installation operation of the nut body 1.

[0027] Among them, the groove 4 is regular hexagon-shaped and can be set according to actual needs to facilitate the rotational operation of the nut body 1.

[0028] Working principle: When the device of the present utility model is in use, the side of the nut body 1 with the elastic washer 2 is oriented towards the part side. By tightening the nut body 1 and an external bolt, the elastic washer 2 is pressed between the nut body 1 and the part. Through the combined action of the elastic force of the elastic washer 2 and the anti-slip blocks 5 thereon, the installation reliability of the nut body 1 can be effectively improved. And by pressing the nut body 1 and the elastic leather ring 3, the elastic leather ring 3 can be expanded to a certain extent, so that the side wall of the elastic leather ring 3 closely adheres to the side wall of the bolt, further improving the installation reliability of the nut body 1. And when the installation space inside the device is small and it is not conducive to inserting a wrench for operation, a tool adapted to the groove 4 can be selected and inserted into the groove 4 to realize the pushing and rotating operation of the nut body 1, which facilitates the installation operation of the nut body 1.
