[0011] Beneficial effects
[0012] This utility model provides a self-tightening multi-wedge anti-slip nut. It has the following advantages: This self-tightening multi-wedge anti-slip nut, through the cooperation of wedge blocks, anti-slip grooves, and a threaded nut, utilizes the external pressure on the wedge surfaces during tightening to generate a self-tightening force when the threaded nut is installed. This allows the nut to automatically tighten during use, effectively preventing loosening and providing a significant anti-slip effect.

[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] In actual use, the anti-slip effect of the gasket is limited, and the anti-loosening rubber is prone to aging, making it inconvenient to disassemble the nut later, thus making it inconvenient to use.
[0021] In view of this, the present invention provides a self-tightening multi-wedge anti-slip nut, which solves the problem that in actual use, the anti-slip effect of the washer is limited and the anti-loosening rubber is prone to aging, making it inconvenient to disassemble the nut later, thus causing inconvenience in actual use.
[0022] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.
[0023] Example 1: By Figure 1-4 It is known that a self-tightening multi-wedge anti-slip nut includes a threaded nut 1, the inner wall of which is provided with threads. The self-tightening multi-wedge anti-slip nut also includes a self-locking device 2, a sealing structure 3, and a shock-absorbing device 4. The self-locking device 2 is installed on the top of the threaded nut 1; the sealing structure 3 is disposed outside the self-locking device 2 and installed on the top of the threaded nut 1; the shock-absorbing device 4 is installed on the inner wall of the threaded nut 1. The self-locking device 2 prevents the threaded nut 1 from falling off, the sealing structure 3 seals the gaps on the threaded nut 1, and the shock-absorbing device 4 reduces the vibration experienced by the threaded nut 1.
[0024] In the specific implementation process, it is worth noting that the inner wall of the threaded nut 1 is provided with threads, which can be connected with the threads on the outer wall of the threaded rod. Under the action of the self-locking device 2, the threaded nut 1 is locked onto the screw rod to prevent it from falling off. At the same time, when the threaded nut 1 is locked, the sealing structure 3 will seal the gap between the threaded nut 1 and the screw rod, which plays a role in sealing and anti-slip. Moreover, with the cooperation of the shock absorption device 4, the vibration received by the threaded nut 1 is offset, thereby preventing the threaded nut 1 from falling off.
[0025] Furthermore, the self-locking device 2 includes wedge blocks 21 and anti-slip patterns 22. Several wedge blocks 21 are provided, all of which are fixedly connected to the top of the threaded mother body 1 in a ring shape. The anti-slip patterns 22 are provided on the top of several wedge blocks 21. The threaded mother body 1 is self-locked by the wedge blocks 21 and the anti-slip patterns 22.
[0026] In the specific implementation process, it is worth noting that anti-slip texture 22 is provided on the top of the wedge block 21. The anti-slip texture 22 is composed of multiple intersecting lines, which can effectively increase the friction of the wedge block 21. Moreover, when the wedge block 21 is squeezed, it generates a self-tightening force under external pressure.
[0027] Furthermore, the sealing structure 3 includes an annular groove 31 and a sealing gasket 32. The annular groove 31 is formed at the top of the threaded body 1; the sealing gasket 32 is inserted into the interior of the annular groove 31; wherein, through the cooperation of the annular groove 31 and the sealing gasket 32, the gaps in the threaded body 1 are sealed.
[0028] In the specific implementation process, it is worth noting that the sealing gasket 32 is made of rubber and is ring-shaped. The size of the annular groove 31 is the same as the shape of the sealing gasket 32, which can ensure that the sealing gasket 32 is inserted into the annular groove 31, and ensure that the sealing gasket 32 seals the gap between the threaded mother body 1 and the screw. At the same time, the sealing gasket 32 can increase the friction between the threaded mother body 1 and the external parts.
[0029] Specifically, when using this self-tightening multi-wedge anti-slip nut, when the threaded nut 1 is installed on the external component, the wedge block 21 at the top of the threaded nut 1 presses against the outer wall of the external component. At the same time, when the wedge block 21 is squeezed, it generates a self-tightening force, making the threaded nut 1 and the external component more tightly connected. Furthermore, the anti-slip texture 22 on the outer wall of the wedge block 21 can increase the friction between the wedge blocks 21, making the threaded nut 1 and the external component more tightly connected. Meanwhile, the sealing gasket 32 at the top of the threaded nut 1 will seal the gap between the threaded nut 1 and the external component, preventing impurities from entering. At the same time, it increases the friction of the part of the threaded nut 1 in contact with the external component, preventing the threaded nut 1 from loosening.
[0030] Example 2: From Figure 1-4 It is known that the shock absorption device 4 includes a mounting groove 41, a shock absorption pad 42, and an internal thread 43. The mounting groove 41 is opened at the top of the threaded mother body 1; the shock absorption pad 42 is inserted into the inner wall of the mounting groove 41; the internal thread 43 is provided on the inner wall of the shock absorption pad 42; wherein, through the cooperation of the mounting groove 41 and the shock absorption pad 42, the threaded mother body 1 is damped, and the internal thread 43 makes the shock absorption pad 42 fit tightly with the bolt.
[0031] In the specific implementation process, it is worth noting that a shock-absorbing pad 42 is installed on the inner wall of the threaded mother body 1. The shock-absorbing pad 42 cancels out the vibration of the threaded mother body 1, reducing the vibration of the threaded mother body 1. Moreover, the internal thread 43 on the inner wall of the shock-absorbing pad 42 will make the shock-absorbing pad 42 in close contact with the screw, thereby better absorbing vibration and reducing the vibration of the threaded mother body 1. At the same time, the shock-absorbing pad 42 is made of rubber. Through the good deformation properties of rubber, kinetic energy is absorbed, thereby preventing the threaded mother body 1 from loosening.
[0032] Furthermore, chamfers 11 are provided on both the upper and lower sides of the outer wall of the threaded body 1;
[0033] In the specific implementation process, it is worth noting that the chamfer 11 facilitates the alignment and installation of nuts and bolts, thereby improving installation efficiency.
[0034] Specifically, based on the above embodiments, when installing the threaded nut 1, the chamfer 11 on its outer wall makes it easier to install, and when the threaded nut 1 and the bolt are subjected to vibration, the shock-absorbing pad 42 will absorb the vibration transmitted from the bolt to the threaded nut 1, thereby preventing it from falling off or loosening.
[0035] 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.
