[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] The present invention is further described in detail below in conjunction with the embodiments.

[0021] like Figure 1-3 As shown, a specific embodiment 1 of an anti-loosening anti-counterfeiting and anti-theft nut kit provided by the utility model:

[0022] An anti-loosening anti-counterfeiting and anti-theft nut kit comprises an eccentric gasket 1 and a nut body 2, wherein a positioning groove 3 is arranged on the eccentric gasket 1, and a positioning boss 4 is arranged at the bottom of the nut body 2, wherein the positioning boss 4 and the positioning groove 3 are both truncated cone-shaped, and the positioning boss 4 is adapted to the positioning groove 3;

[0023] The eccentric gasket 1 is provided with a through hole 5, which passes through the positioning groove 3 on the eccentric gasket 1. The through hole 5 is used for a bolt to pass through. The axis of the through hole 5 and the axis of the positioning groove 3 are parallel to each other and do not overlap.

[0024] The nut body 2 has a threaded hole 6 which passes through the positioning boss 4 on the nut body 2 . The threaded hole 6 is matched with the external thread of the bolt. The axis of the threaded hole 6 and the axis of the positioning boss 4 are parallel to each other and do not overlap.

[0025] When in use, the nut body 2 and the eccentric gasket 1 are assembled through the positioning boss 4 and the positioning groove 3. After assembly, the axis of the through hole 5 and the threaded hole 6 coincide with each other, and the axis of the positioning groove 3 coincides with the axis of the positioning boss 4. Then, the through hole 5 of the eccentric gasket 1 is aligned with the bolt 100, and the nut body 2 is screwed, so that the eccentric gasket 1 and the nut body 2 can be installed on the bolt 100 together; during use, the setting of the eccentric gasket 1, on the one hand, increases the contact area between the nut body 2 and the connected parts, can distribute the pressure more evenly, and prevent the surface of the parts from being damaged due to concentrated force, and on the other hand, can effectively prevent the nut body 2 from gradually loosening in a vibration environment. In particular, in this embodiment, when the nut body 2 has the potential energy to rotate around the bolt 100, but the nut body 2 is in the positioning groove 3 of the eccentric gasket 1, and the axis of the positioning groove 3 does not coincide with the axis of the bolt 100, it can limit or prevent the nut body 2 from rotating in the positioning groove 3, thereby achieving a better anti-loosening function.

[0026] like Figure 4 and Figure 5 As shown, a specific embodiment 2 of an anti-loosening anti-counterfeiting and anti-theft nut kit provided by the utility model is as follows:

[0027] An anti-loosening anti-counterfeiting and anti-theft nut kit comprises an eccentric gasket 1 and a nut body 2, a positioning groove 3 is arranged at the bottom of the nut body 2, a positioning boss 4 is arranged at the top of the eccentric gasket 1, the positioning boss 4 and the positioning groove 3 are both truncated cone-shaped, and the positioning boss 4 is adapted to the positioning groove 3;

[0028] The eccentric gasket 1 is provided with a through hole 5, which passes through the positioning boss 4. The through hole 5 is used for a bolt to pass through. The axis of the through hole 5 and the axis of the positioning boss 4 are parallel to each other and do not overlap.

[0029] The nut body 2 has a threaded hole 6 which passes through the positioning groove 3 on the nut body 2 . The threaded hole 6 is matched with the external thread of the bolt. The axis of the threaded hole 6 and the axis of the positioning groove 3 are parallel to each other and do not overlap.

[0030] The use process of the nut body 2 and the eccentric washer 1 in this embodiment is the same as that in the first embodiment. Similarly, when the nut body 2 has the potential energy to rotate around the bolt, the nut body 2 is located on the positioning boss 4 of the eccentric washer 1, and the axis of the positioning groove 3 does not coincide with the axis of the bolt, so that the nut body 2 can be restricted or prevented from rotating in the positioning boss 4, thereby achieving a better anti-loosening function;

[0031] The difference from Example 1 is that, in order to further improve the anti-loosening effect, a plurality of mounting holes 7 are opened on the eccentric gasket 1. The eccentric gasket 1 is fixed to the connected parts by screws at the mounting holes 7. The eccentric gasket 1 is squeezed and fixed by the nut body 2 on the one hand, and is also fixed by the screws on itself on the other hand. The double fixing method greatly improves the stability of the eccentric gasket 1, making it more difficult to remove the nut body 2 together with the eccentric gasket 1 from the bolt. Furthermore, the through hole 5 of the eccentric gasket 1 can have an internal thread 8, which is compatible with the external thread of the bolt. The bolt is threadedly connected to the eccentric gasket 1 and the nut body 2. The eccentric gasket 1 is equivalent to another "nut", and the setting of the double nut further improves the anti-loosening performance.

[0032] It should be noted that, in this article, terms such as "comprises", "includes" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or apparatus that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or apparatus.

[0033] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
