Embodiment

[0013] Example: such as figure 1 The gas spring with integral guide device shown includes a cylinder body 1, a guide sleeve 3 and a piston rod 4 passing through the guide sleeve 3 and extending out of one end of the cylinder body 1. The inner hole of the guide sleeve 3 is close to the two sides of the guide sleeve 3. A radial inner ring groove is provided at the end, a lip-shaped seal ring 2 is provided in the radial inner ring groove, a fixed partition 6 is installed on the side of the guide sleeve 3 close to the piston 7, and the fixed partition 6 serves as a fixed guide sleeve 3 The role of the guide sleeve 3 is provided with two O-ring 5 on the outer circumference.

[0014] A cavity 9 is provided between the radially inner ring grooves of the inner hole of the guide sleeve 3, and a certain amount of hydraulic oil is injected into the cavity 9. The cavity 9 passes through the hole 10 and is connected to the radial outer ring groove provided on the outer diameter of the guide s...

Abstract

The invention discloses a gas spring with an integrated guide, which relates to the technical field of machinery manufacturing. The gas spring comprises a cylinder body, a guide sleeve and a piston rod, the piston rod runs through the guide sleeve and extends out of one end of the cylinder body, the bore of the guide sleeve is provided with radial inner annular grooves close to both ends of the guide sleeve, lip-shaped sealing rings are arranged in the radial inner annular grooves, and a fixed partition is arranged at one end of the guide sleeve. The invention can solve the problem that since the guide sections of the guides of gas springs are overshort and the guide precision is low at present, the abrasion of the gas springs in use are severe, and as a result, the service lives of the gas springs are affected.

Description

Technical field [0001] The invention relates to the technical field of mechanical manufacturing, in particular to a gas spring with an integral guiding device. Background technique [0002] Gas spring is a kind of mechanical accessories that can support, buffer, brake, height adjustment and angle adjustment. It is widely used in automobiles, textile machinery, printing equipment, office equipment, engineering machinery and other industries; gas spring is a kind of Cylinder body, piston rod, hydraulic oil and gas are mechanical parts that cooperate with each other to work. In the prior art, the gas spring is guided and sealed through the guide sleeve, oil seal, spacer and piston at the extension end of the piston rod in the cylinder. The piston rod keeps running in a straight line in the cylinder, which is generally achieved through the inner hole of the guide sleeve and the cooperation of the piston and the cylinder; this kind of guide device may not be the same as the force of t...
