Description

Technical Field

[0001] This utility model relates to the field of nut technology, specifically to an anti-slip nut assembly. Background Technology

[0002] A nut is a metal or non-metal part with internal threads, usually hexagonal or other polygonal in shape. Its main function is to cooperate with bolts or screws to achieve fastening and connection of parts by tightening.

[0003] Current nuts do not have anti-slip function. When two profiles are connected by nuts and bolts, the profiles have multiple grooves for the nut to move. The surfaces of the current nuts and profiles are smooth, which makes it easy for the nut to slide on the surface of the profile. After installation, the nut may slide due to external force, resulting in an unstable connection. Utility Model Content

[0004] The purpose of this invention is to provide an anti-slip nut assembly to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an anti-slip nut assembly, comprising a nut body, a threaded hole on the surface of the nut body, mounting grooves on both the left and right sides of the bottom of the nut body, a movable block slidably connected to the front and rear sides of the upper part of the mounting groove, a spring body fixed below the movable block, and a mounting block fixed to the bottom end of the spring body, a connecting rod provided below the mounting block, and anti-slip reinforcing plates provided on the front and rear sides of the left and right sides below the nut body.

[0006] Preferably, the bottom end of the connecting rod extends to the outside of the mounting groove and is fixedly connected to the top of the anti-slip reinforcement plate, and the top end of the connecting rod is rotatably connected to the bottom of the mounting block.

[0007] Preferably, a guide rod is fixed above the inner wall of the mounting groove, and the guide rod passes through the movable block and is slidably connected to the movable block.

[0008] Preferably, a fixing block is fixed to the top surface of the mounting block, and the spring body is sleeved on the outside of the fixing block. A positioning groove is formed on the top surface of the fixing block. A positioning rod is fixed to the bottom of the moving block, and the spring body is sleeved on the outside of the positioning rod. The positioning rod is slidably connected to the inner wall of the positioning groove.

[0009] Preferably, a plurality of anti-slip sheets are adhered to the surface above the anti-slip reinforcement plate, and the anti-slip sheets are made of wear-resistant rubber.

[0010] Preferably, the anti-slip reinforcement plate has grooves on the left side of both the front and rear surfaces, and the inner walls of the grooves are inclined.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] This invention features an anti-slip function. Multiple movable anti-slip plates are located beneath the nut, and springs pull these plates upwards. The upward force applied to the anti-slip plates, combined with the downward force applied to the nut, creates a clamping effect. This bidirectional force application significantly increases the friction between the nut and the profile, effectively preventing the nut from sliding within the profile's groove. Even under vibration, impact, or external force, the nut remains stable and will not easily loosen or slip, significantly improving the reliability of the connection. Because the anti-slip plates can be pulled by springs, this design allows the nut assembly to adapt to profiles of different thicknesses, further enhancing the nut's practicality.

[0019] 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.

[0020] Please see Figure 1-5As shown, an anti-slip nut assembly includes a nut body 1, a threaded hole 2 on the surface of the nut body 1, mounting grooves 3 on the left and right sides of the bottom of the nut body 1, a movable block 4 slidably connected to the front and rear sides of the upper part of the mounting groove 3, a spring body 5 fixed below the movable block 4, and a mounting block 6 fixed to the bottom end of the spring body 5. A connecting rod 7 is provided below the mounting block 6, and anti-slip reinforcing plates 8 are provided on the front and rear sides of the left and right sides below the nut body 1.

[0021] The bottom end of the connecting rod 7 extends to the outside of the mounting groove 3 and is fixedly connected to the top of the anti-slip reinforcement plate 8. The top end of the connecting rod 7 is rotatably connected to the bottom of the mounting block 6. After the nut and bolt are connected and fixed, the workers can push the anti-slip reinforcement plates 8 on both sides, thereby causing the anti-slip reinforcement plates 8 to rotate so that the top of the anti-slip reinforcement plate 8 fits against the surface below the profile, thereby reinforcing the nut with anti-slip properties.

[0022] A guide rod 9 is fixed above the inner wall of the mounting groove 3, and the guide rod 9 passes through the movable block 4 and is slidably connected to the movable block 4. A fixing block 10 is fixed to the top surface of the mounting block 6, and the spring body 5 is sleeved on the outside of the fixing block 10. A positioning groove 11 is opened on the top surface of the fixing block 10. A positioning rod 12 is fixed to the bottom of the movable block 4, and the spring body 5 is sleeved on the outside of the positioning rod 12. The positioning rod 12 is slidably connected to the inner wall of the positioning groove 11. Through the setting of the guide rod 9, the operator can slide the anti-slip reinforcement plate 8 back and forth. Adjustment is made to move the anti-slip reinforcement plate 8 to a suitable position according to the profile and the groove on the profile surface, so that the anti-slip reinforcement plate 8 can be reinforced and anti-slip treatment can be carried out later. In order to avoid the spring body 5 bending when the mounting block 6 pulls the upper moving block 4, the operator can push the anti-slip reinforcement plate 8 upward when adjusting the position of the anti-slip reinforcement plate 8, so that the mounting block 6 pushes the fixing block 10 up, so that the positioning rod 12 is inserted into the positioning groove 11. Then the operator can drag the moving block 4 so that the moving block 4 slides on the surface of the guide rod 9.

[0023] Several anti-slip pieces 13 are bonded to the surface above the anti-slip reinforcement plate 8. The anti-slip pieces 13 are made of wear-resistant rubber. Grooves 14 are provided on the left side of both the front and rear surfaces of the anti-slip reinforcement plate 8. The inner wall of the groove 14 is inclined. The anti-slip pieces 13 can further improve the anti-slip reinforcement effect of the anti-slip reinforcement plate 8 on the nut, preventing the nut from slipping. Moreover, when the anti-slip reinforcement plate 8 rotates, the grooves 14 facilitate the movement of the anti-slip reinforcement plate 8 to the surface below the profile for reinforcement and anti-slip treatment.

[0024] Working principle: When the worker installs the nut, the worker places the nut above the groove of the profile, then removes the bolt and passes it through the threaded hole 2 on the surface of the nut body 1. After the bolt is connected to the nut body 1 and passes through the groove on the surface of the profile, the worker pushes the anti-slip reinforcing plates 8 on both sides, causing the anti-slip reinforcing plates 8 to rotate outwards, so that the anti-slip reinforcing plates 8 rotate to the surface below the profile. When the top of the anti-slip reinforcing plate 8 is in contact with the bottom surface of the profile, the installation operation of the nut body 1 is completed. The nut is located above the profile and applies force downwards, while the spring body 5 retracts, causing the anti-slip reinforcing plate 8 to apply force upwards. Through the nut body 1 and the anti-slip reinforcing plate 8, the nut is clamped on the surface of the profile, thereby achieving the purpose of anti-slip.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
