[0024] See Figures 1 to 3As shown, a shock-absorbing pad with a limiting connection includes a shock-absorbing washer body 1, and a protruding ring 2 integrally formed on the inner edge of the top surface of the shock-absorbing washer body; the shock-absorbing washer body is a rubber structural component or a plastic structural component. In this embodiment, the height of the protruding ring can be set as needed, and the outer diameter of the protruding ring is smaller than the outer diameter of the shock-absorbing washer body; a guide chamfer is provided on the top edge of the inner wall of the protruding ring. The guide chamfer can guide the internal structure during insertion, reducing assembly difficulty and improving assembly efficiency.

[0025] Meanwhile, the convex ring is provided with several radially U-shaped grooves 3 at equal intervals for limiting, and the shock-absorbing washer body and the inner wall of the convex ring are integrally formed with several axially grooved grooves 4 for positioning. The axial grooves and radially U-shaped grooves are staggered; that is, when connected with corresponding structures, connection limiting can be achieved at different positions, which can ensure the stability and effectiveness of the connection. The depth of the radially U-shaped groove matches the height of the convex ring. The depth of the axial groove is 1 / 3 to 1 / 2 of the width of the side wall of the convex ring. In this embodiment, the number of radially U-shaped grooves and axial grooves is three or four. The radial cross-section of the axial groove is an isosceles trapezoid.

[0026] In this embodiment, a limiting protrusion 5 is integrally formed on the outer wall of the damping washer body, and an axial limiting groove 6 is integrally formed on the outer side of the limiting protrusion. The limiting protrusion can improve the local strength of the damping washer body, and the integrity of the overall damping washer body can be avoided when processing the axial limiting groove, thereby ensuring the stability and reliability of the damping washer body in use.

[0027] In this embodiment, a radial damping groove 7 is provided in the middle of the outer wall of the damping washer body, and the two ends of the radial damping groove extend to the symmetrical sides of the limiting protrusion. The radial damping groove can improve the effectiveness of damping.

[0028] In this embodiment, the outer surface of the limiting protrusion is provided with two clearance grooves 8, and the two clearance grooves are symmetrically arranged at the symmetrical edges of the axial limiting groove. The depth of the clearance grooves can be set as needed, and its depth is much smaller than the depth of the axial limiting groove.

It has a raised ring on the top surface of the shock-absorbing washer, which increases the overall structural thickness. Furthermore, it features a radial U-shaped groove that works in conjunction with an axial groove. When connected to inner components, the axial and radial U-shaped grooves can engage and limit the movement of the protrusions on the components, ensuring the stability and effectiveness of the installation.
