For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0028] In the description of the present invention, "plurality" means two or more than two, unless otherwise clearly and specifically defined.

[0029] Please refer to Figure 1-Figure 4 , a bolt fastener of an electric power fitting, comprising a bolt part 1 and a nut part 2.

[0030] like Figure 1 and Figure 2 As shown, a bolt structure is provided on the bolt member 1, and a plurality of interruptions are provided on the bolt structure, and the plurality of interruptions form a plurality of fixing grooves 1b.

[0031] In this embodiment, two adjacent discontinuities on the bolt structure are located on the same Y-axis, so that a plurality of fixing grooves 1b formed by the discontinuities are vertical.

[0032] In this embodiment, a number of interruptions form four fixing grooves 1b, the angle between any two adjacent fixing grooves 1b is equal, and the fixing grooves 1b are arranged on the threaded structure 1a along the directions of 0°, 90°, 180° and 270°; it is natural that the number of fixing grooves 1b can also be other, and can be flexibly set according to usage requirements, and this is not limited here.

[0033] like Figure 1 and Figure 3 As shown, the nut member 2 includes a nut body 21, a plurality of fixing plates 22 and a fixing block 23; the nut body 21 is cylindrical and has an internal thread that matches the thread structure 1a of the bolt member 1; a plurality of through grooves 21a are provided on the nut body 21. When the nut body 21 is installed on the bolt member 1, the through grooves 21a are aligned with the fixing grooves 1b, and then a plurality of fixing plates 22 are inserted into the fixing grooves 1b through the through grooves 21a. The fixing block 23 is sleeved on the nut body 21 and abuts against the outer side of the fixing plate 22 to prevent the fixing plate 22 from falling off from the fixing groove 1b.

[0034] When the device vibrates, the fixing plate 22 will limit the relative sliding between the nut body 21 and the bolt member 1 to prevent the nut body 21 from loosening.

[0035] It should be noted that the width of the fixing groove 1 b is the same as the width of the first plate body 221 , thereby limiting the rotation of the nut body 21 .

[0036] Specifically, Figure 4 As shown, the fixing plate 22 has a first plate body 221 and two second plate bodies 222, and the two second plate bodies 222 are located on opposite sides of the first plate body 221. When the fixing plate 22 enters the fixing groove 1b through the through groove 21a, the outer surfaces of the two second plate bodies 222 are flush with the outer surface of the nut body 21, and the first plate body 221 extends to the outside of the through groove 21a; there are two fixing blocks 23, which are respectively sleeved on both ends of the nut body 21, respectively pressing against one end of the first plate body 221 extending to the outside and the outside of the second plate body 222, so as to better limit the separation of the fixing plate 22 from the fixing groove 1b; the first plate body 221 extending to the outside of the through groove 21a is convenient for holding, so that the fixing plate 22 can be installed in the fixing groove 1b through the through groove 21a, or the fixing plate 22 can be taken out of the fixing groove 1b.

[0037] More specifically, both ends of the nut body 21 have external threads, and the spiral directions of the external threads are opposite. The two fixing blocks 23 respectively have threaded holes that match the external threads of the nut body 21. The fixing blocks 23 are threadedly connected to the nut body 21, which facilitates the disassembly and installation of the fixing blocks 23. At the same time, the spiral directions of the external threads at both ends of the nut body 21 are opposite, which can better prevent the two fixing blocks 23 from falling off the nut body 21 at the same time.

[0038] The working principle of this embodiment is:

[0039] The nut member 2 is connected to the bolt member 1, and the nut member 2 is stuck in a plurality of fixing grooves 1b. When the device vibrates, the nut member 2 and the bolt member 1 are restricted from sliding relative to each other, thereby preventing the nut member 2 from loosening.

[0040] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
