Description

Technical Field

[0001] The utility model relates to the technical field of washers, in particular to an anti-torsion shock-absorbing washer. Background Art

[0002] Shock-absorbing washers are devices installed between mechanical equipment or components to reduce the transmission of vibration and impact. They are usually made of elastic materials and absorb and disperse vibration energy through elastic deformation inside them, thereby reducing the impact of vibration and impact on equipment or components. Shock-absorbing washers are widely used in the fields of automobiles, ships, aerospace, construction engineering, etc., and are of great significance to improving the operating stability of equipment and extending its service life.

[0003] For example, a Chinese patent document with authorization number CN203477021U discloses a shock-absorbing washer, including a first shock-absorbing part and a second shock-absorbing part, the first shock-absorbing part and the second shock-absorbing part are arranged overlappingly, and a shock-absorbing ball is arranged between the first shock-absorbing part and the second shock-absorbing part; although the above-mentioned shock-absorbing ball arrangement can improve the heat dissipation performance and shock-absorbing effect, the above-mentioned shock-absorbing washer is easily deformed when subjected to torsional force, resulting in poor stability and relative rotation, resulting in wear.

[0004] Therefore, it is necessary to improve the deficiencies in the above prior art. Summary of the invention

[0005] The technical problem to be solved by the utility model is to provide an anti-torsion shock-absorbing washer in view of the above-mentioned deficiencies of the prior art, so as to solve the problems in the prior art of easy deformation resulting in poor stability and relative rotation resulting in wear when subjected to torsional force.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an anti-torsion shock-absorbing washer, comprising a washer body, a through hole is provided in the middle of the washer body, a plurality of mounting blind holes extending radially are evenly distributed in the circumference of the through hole, an elastic member is installed in the mounting blind hole, a telescopic hole is provided in the middle of the elastic member, an abutment portion is provided at one end of the elastic member close to the through hole, the abutment portion can be telescoped in the inner diameter direction through the mounting blind hole, and the other three ends of the elastic member are respectively abutted against the inner wall of the mounting blind hole.

[0007] By adopting the above technical solution, when the washer body of the shock-absorbing washer is squeezed, the upper and lower side walls of the mounting blind hole come together to squeeze the elastic member, so that the upper and lower ends of the elastic member shrink the telescopic hole and approach each other, and the abutting portion extends out of the mounting blind hole and abuts against the connecting member in the through hole, so that the shock-absorbing washer is not prone to relative rotation and wear when subjected to torsional force; in addition, since the washer body is not a layered structure and has good integrity, it is not easy to deform when subjected to torsional force and has better stability; similarly, when the washer body is not squeezed, the elastic member returns to its initial state and the abutting portion retracts into the mounting blind hole.

[0008] The above technical solution is further configured as follows: a slot is provided on a side wall of the mounting blind hole away from the through hole, and a block engaging with the slot is provided at one end of the elastic member close to the slot.

[0009] By adopting the above technical solution, the elastic member is more stable and not easy to fall off by inserting the clamping block of the elastic member into the clamping groove of the installation blind hole.

[0010] The above technical solution is further configured as follows: the cross section of the mounting blind hole is square, and abutment planes are provided at the upper and lower ends of the elastic member.

[0011] By adopting the above technical solution and setting the installation blind hole to have a square cross-section, the elastic member can be limited so that it will not rotate; the upper and lower ends of the elastic member are set as abutment planes to increase the force-bearing area and make the force more balanced.

[0012] The above technical solution is further configured as follows: a circle of a plurality of anti-slip racks is provided on one end surface of the gasket body.

[0013] By adopting the above technical solution, the friction force at the point where the anti-slip rack contacts the connecting piece can be increased, thereby effectively preventing loosening.

[0014] The above technical solution is further configured as follows: a plurality of arc-shaped grooves are annularly distributed on the end surface of the gasket body away from the anti-slip rack.

[0015] By adopting the above technical solution, when the shock-absorbing gasket is squeezed, the gasket body approaches one end of the arc-shaped groove and abuts against the connecting piece, and the air in the arc-shaped groove is discharged. Under the action of atmospheric pressure, the gasket body can be adsorbed on the connecting piece, further making the connecting piece less likely to rotate, thereby improving the anti-torsion effect.

[0016] The beneficial effects achieved by the utility model are that the shock-absorbing washer maintains the stability of its shape and size when subjected to torsion force and is not prone to wear. BRIEF DESCRIPTION OF THE DRAWINGS
