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

[0026] Embodiment one

[0027] See Figures 1-4 An anti-loosening nut structure is characterized by comprising: a nut body 1; an anti-loosening component 2 provided on the nut body 1, the anti-loosening component 2 comprising: a mounting plate 21 fixedly connected to the outer wall of the nut body 1; a sliding groove 22 starting from the outer wall of the mounting plate 21; a fixing block 23 slidably connected to the inside of the sliding groove 22; a rod 24 inserted into the inside of the sliding groove 22 and disposed on the fixing block 23; a spring 25 disposed on the fixing block 23; a groove 26 formed on the outer wall of the nut body 1, and the fixing block 23 slidably connected to the inside of the groove 26; a pull block 5 fixedly connected to one end of the rod 24; and the rod 24 being configured as a threaded rod.

[0028] In use, the operator pulls the rod 24 on the mounting plate 21, causing the rod 24 to move outward from the mounting plate 21. Simultaneously, this moves the fixing block 23 within the groove 22, causing the fixing block 23 to press against the spring 25, thus fully entering the groove 26. The operator then screws the nut body 1 onto the bolt. After tightening, the operator releases the rod 24, causing the spring 25 to spring the fixing block 23 towards the bolt, compressing the bolt and increasing the friction between the bolt and the nut body 1. This prevents the nut body 1 from loosening and improves the stability of the device. The operator can also move the rod 24 by pulling the pull block 5, avoiding the inconvenience of directly pulling the rod 24 due to its smooth surface. Pulling the rod 24 then rotates it, connecting it to the mounting plate 21 via a thread, eliminating the need for constant pulling and improving the device's convenience.

[0029] Example 2

[0030] See Figures 1-4 Based on Embodiment 1, an auxiliary anti-loosening function has been added;

[0031] The nut body 1 is provided with an auxiliary anti-loosening component 3, which includes: a movable plate 31, which is inserted into the mounting plate 21 and slidably connected to the mounting plate 21; a spring 32, which is disposed on the movable plate 31; a rotating column 33, which is rotatably connected to the top of the movable plate 31; a pressure plate 34, which is fixedly connected to the top of the rotating column 33; one side of the fixing block 23 is set as an arc surface; and an anti-slip pad 4 is fixedly connected to the outer wall of the fixing block 23.

[0032] When the bolt is screwed with the nut body 1, the operator pulls the moving plate 31 to stretch the spring two 32, and then rotates the pressing plate 34 by rotating the column 33, so that the pressing plate 34 is pressed on the top of the bolt, and the bolt and the nut body 1 are further prevented from loosening; the side of the fixed block 23 close to the bolt is arc surface, which can increase the contact area with the bolt and improve the friction force; the fixed block 23 moves to drive the non-slip pad 4 to move simultaneously, so that the non-slip pad 4 directly contacts with the bolt, the friction force between the nut body 1 and the bolt is further increased through the non-slip pad 4, and the anti-loosening effect is further improved.

[0033] Although the embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present application, the scope of which is defined by the appended claims and their equivalents.
