DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] like Figure 1-Figure 7As shown, a sealing retaining ring for automobile shock absorber includes a front shock absorber sealing retaining ring 100 and a rear shock absorber sealing retaining ring 200, both of which are made of PA66. The front shock absorber sealing retaining ring 100 and the rear shock absorber sealing retaining ring 200 have good oil resistance, corrosion resistance and impact resistance. The front shock absorber sealing retaining ring 100 is buckled on the piston rod of the front shock absorber, and the rear shock absorber sealing retaining ring 200 is buckled on the piston rod of the rear shock absorber. Reinforcing ribs 300 are arranged in an array on the inner walls of the upper half of the front shock absorber sealing retaining ring 100 and the rear shock absorber sealing retaining ring 200, which can effectively improve the durability and impact resistance of the front shock absorber sealing retaining ring 100 and the rear shock absorber sealing retaining ring 200, and improve the service life of the product.

[0022] The front shock absorber sealing retaining ring 100 is provided with a buckle 101 in an array at the bottom end. The buckle 101 has an L-shaped cross section and a fan-shaped lower half. The front shock absorber sealing retaining ring 100 is provided with a wedge-shaped protrusion 102 in an array on the circumferential surface at the bottom end. The front shock absorber sealing retaining ring 100 is clamped in the dust cover fixing groove of the front shock absorber through the buckle 101, which is convenient for installation. The front shock absorber sealing retaining ring 100 is provided with a convex point 103 in an array on the top, and the convex point 103 is distributed in a matrix. The rear shock absorber sealing retaining ring 200 is provided with a linear groove 201 in an array on the circumferential surface to reduce the overall weight of the rear shock absorber sealing retaining ring 200.
