Detailed Description

The present invention will be further described with reference to the accompanying drawings and the detailed description, and it should be noted that the embodiments or technical features described below can be arbitrarily combined to form a new embodiment without conflict.

As shown in fig. 1-2, the pallet snap ring type shock absorber comprises a cylinder 2 provided with a piston 1, one end of the piston 1 is fittingly arranged in the cylinder 2, the other end of the piston is connected with an upper lifting ring 4 through a connecting sleeve 3, the outer wall of the cylinder 2 is further provided with a dust cover 5 and a dust cover cap 6, the dust cover cap 6 is positioned outside the dust cover 5, the middle part of the cylinder 2 is annularly provided with a limiting groove 7 connected end to end, the outside of the limiting groove 7 is provided with a bracket 8, the inner wall of the bracket 8 is provided with a limiting ring 9 adapted to the limiting groove 7, the limiting ring 9 is clamped in the limiting groove 7, the bracket 8 is provided with a spring tray 10, and a damping spring is arranged between the spring tray 10 and the dust cover cap 6. The bracket 8 is reliably limited on the outer wall of the barrel body 2 through the action of the limiting grooves 7 and the limiting rings 9, a plurality of limiting grooves 7 can be arranged on the outer wall of the barrel body 2, and the limiting grooves 7 are arranged at intervals along the axial direction of the barrel body 2, so that limiting holes are placed in the corresponding limiting grooves 7, the position of the spring tray 10 is adjusted, and the damping force of the damping spring is adjustable; simultaneously, set up bracket 8, the installation of the spring tray 10 of being convenient for on the one hand, fixed, on the other hand spring tray 10 and the contact of bracket 8 have the cushioning effect, have prevented spring tray 10's damage, have avoided breaking away from of spring tray 10 and barrel 2, and the shock attenuation is effectual, and the assembly is reliable, and the durability is high.

The bracket 8 comprises a pair of arc-shaped seat plates 11, the pair of seat plates 11 surround the annular bracket 8, and the spring tray 10 is sleeved on the outer walls of the pair of seat plates 11.
