A buffer ring for anti-slip oil cylinder

Abstract

The utility model belongs to the field of oil cylinder buffer devices, and specifically relates to a buffer ring for an oil cylinder that can prevent it from slipping off.

Technical solution: A buffer ring for an oil cylinder that can prevent it from slipping off, includes a rod head assembly; it also includes a first buffer assembly, a rubber ring, a shock absorbing assembly, and a second buffer assembly. The utility model uses a corrugated groove opened on a first ring block of a flexible material so that the impact or vibration energy received by the first ring block can be dispersed through deformation, thereby preventing the energy from being concentrated in a certain local area, thereby reducing the risk of local stress, and solving the problem that the shock absorbing and anti-impact capabilities of the buffer ring are limited, and that the buffer ring is prone to accidentally slipping and detaching inside the oil cylinder after long-term use, resulting in a reduction in the service life of the oil cylinder buffer ring.

[0002] The anti-slip cylinder is usually composed of a cylinder body, a piston and a piston rod. It is connected to the hydraulic system and uses hydraulic pressure to stabilize and fix the workpiece or work surface.
