Description

Technical Field

[0001] This utility model relates to the field of anti-theft nuts, and in particular to an anti-theft nut. Background Technology

[0002] In the power, telecommunications, and railway industries, equipment often needs to be operated outdoors and installed using nuts, which may lead to theft. Therefore, anti-theft nuts are required for operation.

[0003] To address this, patent CN202165377U discloses an anti-theft nut, characterized by an anti-theft head at one end and a locking end at the other. A connecting portion is provided between the anti-theft head and the locking end, with a cross-section smaller than that of the anti-theft head and the locking end, so that the torsional resistance of the anti-theft head and the locking end is greater than that of the connecting portion. When the anti-theft nut is tightened, the connecting portion breaks off before the anti-theft head and the locking end. In this invention, the anti-theft head and the locking end are connected as one unit by a groove. Compared with the prior art, the advantages of this invention are: reasonable design, simple structure, and the fact that the connecting portion breaks off before the anti-theft head and the locking end when the anti-theft nut is tightened, making it impossible to unscrew the anti-theft head through the locking end.

[0004] The anti-theft nuts mentioned above are difficult to protect and prevent theft during use, which may allow thieves to open the equipment by rotating the nuts, thus failing to meet actual usage needs. Summary of the Invention

[0005] The purpose of this invention is to provide an anti-theft nut to address the shortcomings of existing anti-theft nuts in terms of insufficient anti-theft performance.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an anti-theft nut, comprising a nut head and a threaded rod;

[0007] A threaded rod is fixed to the bottom end of the nut head, and a protective structure is provided on the outer wall of the threaded rod;

[0008] The protective structure includes an anti-theft body with a threaded rod on the outer wall, a gasket on the top of the anti-theft body, a reserved groove at the bottom of the anti-theft body, and a nut at the bottom of the anti-theft body;

[0009] The top of the nut head is provided with an anti-theft structure.

[0010] Preferably, the gasket is slidably connected to the outer wall of the threaded rod, and the anti-theft body is slidably connected to the outer wall of the threaded rod.

[0011] Preferably, the nut is threadedly connected to the threaded rod.

[0012] Preferably, the diameter of the nut is smaller than the inner diameter of the reserved groove, and the nut is disposed inside the reserved groove.

[0013] Preferably, the top end of the washer abuts against the bottom end of the nut head, and the bottom end of the washer abuts against the top end of the anti-theft body.

[0014] Preferably, the anti-theft structure includes an irregularly shaped rotating groove at the top of the nut head, a protruding rod fixed inside the irregularly shaped rotating groove, and an arc-shaped angle on the outer wall of the nut head outside the irregularly shaped rotating groove.

[0015] Preferably, the top end of the protruding rod is aligned with the top end of the nut head.

[0016] The anti-theft nut provided by this utility model has the following advantages:

[0017] By setting up a protective structure, the anti-theft body is slidably connected to the outer wall of the threaded rod, and the diameter of the reserved groove is larger than the diameter of the nut. Thus, when the nut is used to lock and position the equipment, the nut is placed inside the reserved groove, thereby protecting the nut and preventing the nut from rotating and releasing the nut from locking, thus achieving the purpose of protecting the nut and preventing theft.

[0018] By incorporating an anti-theft structure, an arc-shaped corner is provided on the outer wall of the nut head to prevent it from being rotated after being clamped. Furthermore, an irregularly shaped rotating groove is provided at the top of the nut head to facilitate disassembly and assembly. This allows the nut to be disassembled and assembled using only compatible disassembly and assembly handles, thereby improving the anti-theft performance of the nut. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-5 The present invention provides an anti-theft nut, comprising a nut head 1 and a threaded rod 2.

[0027] Reference Figures 1-4 As shown, a threaded rod 2 is fixed to the bottom end of the nut head 1. A protective structure 3 is provided on the outer wall of the threaded rod 2. The protective structure 3 includes an anti-theft body 301 on the outer wall of the threaded rod 2, a washer 302 on the top of the anti-theft body 301, a reserved groove 303 at the bottom end of the anti-theft body 301, and a nut 304 at the bottom of the anti-theft body 301. The washer 302 is slidably connected to the outer wall of the threaded rod 2, the anti-theft body 301 is slidably connected to the outer wall of the threaded rod 2, and the nut 304 is threadedly connected to the threaded rod 2. The diameter of the nut 304 is smaller than the inner diameter of the reserved groove 303. The nut 304 is located inside the reserved groove 303. The top end of the washer 302 abuts against the bottom end of the nut head 1, and the bottom end of the washer 302 abuts against the top end of the anti-theft body 301.

[0028] When the equipment is installed and positioned using nuts and placed outdoors, theft may occur. Furthermore, during long-term use, rainwater may enter the connection between the nut 304 and the threaded rod 2, affecting subsequent rotation. Therefore, by setting up a protective structure 3, the nut 304 is placed inside the reserved groove 303 when tightened. This allows the washer 302 to protect the nut 304 while completely covering the reserved groove 303, making it difficult to loosen the nut's tightness by rotating the nut 304. This prevents theft and greatly increases the practicality of the nut.

[0029] Reference Figure 1 , Figure 2 and Figure 5As shown, the top of the nut head 1 is provided with an anti-theft structure 4. The anti-theft structure 4 includes an irregularly shaped rotating groove 401 opened at the top of the nut head 1. A protruding rod 402 is fixed inside the irregularly shaped rotating groove 401. An arc-shaped angle 403 is opened on the outer wall of the nut head 1 outside the irregularly shaped rotating groove 401. The top of the protruding rod 402 is aligned with the top of the nut head 1.

[0030] When disassembling and maintaining the equipment, the nut needs to be turned to open. To prevent theft, an anti-theft structure 4 is provided. A special-shaped rotating groove 401 is opened at the top of the nut head 1, and a protruding rod 402 is fixed inside it. This means that a matching rotating handle is required to drive the nut head 1 to rotate. Furthermore, an arc-shaped angle 403 is opened on the outside of the nut head 1 to prevent rotation by clamping the outer wall of the nut head 1, thus greatly increasing the practicality of the nut.

[0031] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
