Telescopic hydraulic oil cylinder with buffering and damping structure

Abstract

The invention discloses a telescopic hydraulic oil cylinder with a buffering and damping structure. The telescopic hydraulic oil cylinder with the buffering and damping structure comprises a main body, the buffering and damping structure and a heat dissipation mechanism, the main body comprises a cylinder barrel, a piston rod is connected to the inner wall of the cylinder barrel, and a pushing handle is connected to one end of the piston rod; and the buffering and damping structure comprises a first fixing block located at the bottom end of the pushing handle, a second fixing block is arrangedat the top end of the cylinder barrel, a movable ring is connected to the outer wall of the piston rod, and a fixing rod is connected to the outer wall of the movable ring. According to the telescopic hydraulic oil cylinder with the buffering and damping structure, by arranging the heat dissipation plates, the heat dissipation area of the hydraulic oil cylinder is increased, when the hydraulic oil cylinder stretches or contracts, the movable ring moves to drive a limiting block to move through the fixing rod, the limiting block moves to drive a lead screw to move, the lead screw drives a fanto rotate, air flowing between the heat dissipation plates is accelerated, and the heat dissipation efficiency is improved; and heat dissipation of the hydraulic oil cylinder is facilitated.

Description

technical field [0001] The invention relates to the field of hydraulic cylinders, in particular to a telescopic hydraulic cylinder with a shock absorbing structure. Background technique [0002] The hydraulic cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and performs linear reciprocating motion (or swinging motion). It has a simple structure and reliable operation. When it is used to realize reciprocating motion, the deceleration device can be eliminated and there is no transmission gap. , The movement is smooth, so it is widely used in various mechanical hydraulic systems. [0003] However, the current hydraulic cylinder is to install a buffer pad on the cylinder head to overcome the impact of the piston on the cylinder head, which can not be well cushioned and shock-absorbing; at the same time, the hydraulic cylinder will generate a higher temperature if it works for a long time. In the working state, it will affect the performance...

[0003] However, the current hydraulic cylinder is to install a buffer pad on the cylinder head to overcome the impact of the piston on the cylinder head, which cannot be well cushioned and shock-absorbed; at the same time, the hydraulic cylinder will generate a higher temperature if it works for a long time, and it will be at a high temperature for a long time. Under working conditions, it will affect the performance of the cylinder and shorten the service life of the cylinder
