Description

Technical Field

[0001] The utility model relates to the technical field of shock-absorbing guides, in particular to a tray bracket type shock-absorbing guide. Background Art

[0002] Shock absorbers are used to suppress the shock of the spring rebounding after absorbing the shock and the impact from the surface. They are widely used in automobiles to accelerate the attenuation of the vibration of the frame and body to improve the driving smoothness of the car. When passing through uneven surfaces, although the shock-absorbing spring can filter the vibration of the surface, the spring itself will still have reciprocating motion, and the shock absorber is used to suppress this spring jumping.

[0003] In the prior art, the tray bracket type shock absorber uses high-quality materials to make the tray, and the mounting bracket is integrated into the shock absorber body in accordance with the suspension fixing requirements in structure, so that the damping force of the shock absorber is more concentrated on the reciprocating motion block diameter of the coil spring. When the shock absorber is working, the piston rod slides rapidly along the inner wall of the shock absorber cylinder under the action of the spring, and a guide needs to be set on the top of the cylinder to guide it to maintain the stability and controllability of the vehicle. However, when the piston rod slides on the inner wall of the guide for a long time, the gap between the inner walls is large, which easily causes the oil inside the installation cylinder to leak out from the plug rod between the inner walls of the guide, and the sealing effect is poor. Utility Model Content

[0004] The utility model aims to solve the problem in the prior art that when the piston rod slides on the inner wall of the guide for a long time, the gap between the inner walls is large, which easily leads to the leakage of oil inside the installation cylinder from the piston rod between the inner walls of the guide and the poor sealing effect, and a tray bracket type shock-absorbing guide is proposed.

[0009] Preferably, the top of the first inner ring block fits with the bottom of the second inner sealing ring, and the bottom of the second inner ring block fits with the top of the first inner sealing ring.

[0010] Preferably, the outer surfaces of the plurality of fixing rods all slide through the outer surface of the mounting ring block, and the bottom of the mounting ring block fits with the inner bottom of the guide body.

[0011] Preferably, a gasket is provided on the movable sleeve of the outer surface of the fixing rod, and the gasket is located between the mounting ring block and the hexagonal nut.

This solves the problem in the background technology that when the piston rod slides on the inner wall of the guide for a long time, the gap between the inner walls is large, which easily causes the oil inside the installation cylinder to leak out from the plug rod between the inner walls of the guide, resulting in poor sealing effect.

[0015] 2. In the utility model, when in use, the sealing block is threadedly connected to the inner surface of the guide body to play a sealing role to prevent dust from entering the interior thereof.
