[0004] Similar to spring washers, when spring washers are subjected to torque and force, they will produce a certain deformation and resist the influence of external torque or force through elastic restoring force. Due to the passage of time and frequent torque action, the elastic properties of spring washers will change, and the anti-torque or shock absorption effect they provide will gradually weaken, resulting in attenuation.

[0005] Therefore, in view of this, the shortcomings of the existing structure are studied and improved, and a concave anti-torque attenuation spring washer structure is proposed. Utility Model Content

[0006] The purpose of the utility model is to provide a recessed anti-torque attenuation spring washer structure. When the spring washer is subjected to torque and force, it will produce a certain deformation and resist the influence of external torque or force through elastic restoring force.

[0021] The following is a further detailed description of the implementation of the present utility model in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present utility model, but cannot be used to limit the scope of the present utility model.

[0022] like Figures 1 to 4As shown, a concave anti-torque attenuation spring washer structure includes a first bolt body 1, a washer 3, a spring washer body 4, a concave layer 5 and a magnet 6. The lower end of the outer surface of the first bolt body 1 is provided with a first external thread 2. The first bolt body 1 provides connection and support, and the connection with other components is achieved through the first external thread 2 to maintain the stability of the overall structure. The washer 3 is sleeved on the outer surface of the first bolt body 1. The washer 3 plays a filling and buffering role to ensure the stability and uniformity of the bolt connection and reduce the possibility of vibration and loosening.

[0023] The spring washer body 4 is arranged at the upper end of the gasket 3, and the upper and lower end faces of the spring washer body 4 are respectively abutted against the first bolt body 1 and the gasket 3, and the shape of the outer surface of the spring washer body 4 is spiral. The spring washer body 4 with a spiral cut is a screw component with pre-tension and rebound force, which is used to prevent the first bolt body 1 from loosening and buffer vibration. The magnets 6 are arranged at the ends of both ends of the spring washer body 4. There are two groups of magnets 6. Through the repulsion principle of the magnets 6, a repulsive force can be generated to repel the contact surface between the ends of the spring washer body 4, thereby increasing stability and anti-torque capability, and enhancing the resilience at the cut by the repulsive force, so that it can return to its original state more quickly to prevent the service life from being attenuated. The ends of the two groups of magnets 6 facing the positive poles correspond to each other, and the two groups of magnets 6 are respectively arranged in the inner cavity of the ends of the spring washer body 4. Through the arrangement of the ends of the two groups of magnets 6 facing the positive poles corresponding to each other, a repulsive force can be generated to repel the contact surface between the ends of the spring washer body 4;

[0024] The concave layer 5 is arranged at the upper and lower ends of the spring washer body 4. The concave layer 5 is provided with a plurality of groups, and the plurality of groups of concave layers 5 are arranged in a stepped manner. The design of the concave layer 5 arranged in a stepped manner can disperse the impact force through the uneven surface structure when subjected to external impact force, reduce the direct impact on the spring washer body 4, and extend the service life of the part. The inner surface of the spring washer body 4 is embedded with a reinforcing rib 7. The arrangement of the reinforcing rib 7 on the inner surface of the spring washer body 4 can increase the overall strength of the part, disperse the external pressure, and make it evenly distributed on the spring washer body 4, reduce local stress concentration, prevent deformation or rupture when subjected to force, and improve the bearing capacity of the part;

[0025] A threaded hole 8 is provided on the outer surface of the spring washer body 4. There are two groups of threaded holes 8. The threaded holes 8 provide a connection function. The inner surfaces of the two groups of threaded holes 8 are provided with second bolts 9. The second bolts 9 can provide supporting force, making the connection more secure and preventing loosening or falling off. The outer surface of the second bolt 9 is provided with a second external thread 10. The threaded hole 8 and the second external thread 10 have the same aperture size, and the threaded hole 8 and the second external thread 10 are meshed with each other. The meshing between the threaded hole 8 and the second external thread 10 can be connected and disassembled by rotation. The two groups of second bolts 9 respectively penetrate the spring washer body 4 and abut the outer surface of the first bolt body 1. The positions of the two groups of second bolts 9 are horizontally corresponding. The second bolts 9 penetrate the outer surface of the spring washer body 4 and the first bolt body 1, and form a stable connection by meshing with the second external thread 10. The two groups of second bolts 9 are horizontally corresponding to each other to ensure the balance and stability of the connection.

[0026] In summary, if Figures 1 to 4 As shown, the recessed anti-torque attenuation spring washer structure, when the first bolt body 1 is used to connect with an external device, the spring washer body 4 is flattened, and the spring washer body 4 generates a continuous elastic force, which acts between the first bolt body 1 and the gasket 3, and then the nut and the first external thread 2 of the first bolt body 1 are rotated and tightened, and a friction force is continuously maintained to generate a resistance torque to prevent the nut from loosening. The contact surface position between the ends of the spring washer body 4 is through the two groups of magnets 6 set. Since the two groups of magnets 6 with the same polarity are brought close to each other, a repulsion principle will be generated. When two magnets 6 with the same polarity are close to each other, a repulsion force will be generated between them, causing them to repel each other. The two groups of magnets 6 are set at the ends of the contact surface of the spring washer body 4, so that they repel each other, increase the anti-torque ability of the washer, and use the repulsion principle to increase the resilience of the spring washer body 4. When the flattening is cancelled, the washer will quickly return to its original state;

[0027] When the spring washer body 4 is subjected to stress, the concave layer 5 on its surface is arranged in a stepped manner so that when the spring washer body 4 is subjected to external impact force, the impact force can be dispersed through the uneven surface structure to reduce the direct impact on the spring washer body 4. The reinforcing rib 7 is dispersed by being arranged on the inner surface of the spring washer body 4 to make it evenly distributed on the spring washer body 4, thereby reducing local stress concentration. The second external thread 10 on the outer surface of the second bolt 9 is engaged with the threaded holes 8 on both sides of the spring washer body 4. The connection and disassembly are achieved by rotating the second bolt 9. When in use, the second bolt 9 is tightened to abut against the outer surface of the first bolt body 1 to achieve fixation.
