Abstract
The utility model discloses a novel limiting sleeve structure of built-in spring, include: a stop collar and a lining; one end of the limiting sleeve is a sleeving part, the other end of the limiting sleeve is a limiting part, and a clamping groove is formed in the inner wall of the limiting part; the inner lining is fixedly embedded in the clamping groove; the utility model discloses set up the inside lining in the metal stop collar, through stop collar fixed spring, inside lining and piston rod clearance connection have not only avoided the yielding problem of non-metallic stop collar in high temperature damping oil, have still solved the great problem of all-metal stop collar to piston rod frictional force, and practicality and life are promoted by a wide margin.
Description
Technical Field
The utility model relates to a machine parts field, more specifically the utility model relates to a novel limiting sleeve structure of innerspring.
Background
At present, the stop collar applied to the movable end of the innerspring in the hydraulic double-tube shock absorber is generally known to be made of non-metal materials (such as nylon, polyurethane and the like) or all-steel materials. The limiting sleeve is soaked in shock absorption oil, and the temperature of the shock absorber is generally between the outdoor environment temperature and 70 ℃ when the shock absorber works. The non-metal material is easy to deform in the environment for a long time, and particularly when the innerspring works under the impact, abnormal sound of the shock absorber can be caused, and the shock absorber is seriously clamped and fails. The friction force between the all-steel limiting sleeve and the piston rod of the shock absorber is large, and the piston rod is easy to wear, so that the service life of the shock absorber is shortened; and the piston rod is pulled to be damaged when the shock absorber is serious, so that the shock absorber is discarded due to oil leakage.
Therefore, how to provide an innerspring retainer ring structure with a longer service life is an urgent problem to be solved by those skilled in the art.
SUMMERY OF THE UTILITY MODEL
In view of this, the utility model provides an innerspring stop collar structure through inlay the inside lining admittedly at the metal stop collar, strengthens its life to reduce the wearing and tearing of piston rod, effectively prolong the life of stop collar and piston rod.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
a novel limit sleeve structure of an innerspring comprises: a stop collar and a lining;
one end of the limiting sleeve is a sleeving part, the other end of the limiting sleeve is a limiting part, and a clamping groove is formed in the inner wall of the limiting part; the inner liner is fixedly embedded in the clamping groove.
According to the technical scheme, compare with prior art, the utility model discloses a novel limiting sleeve structure of built-in spring inlays the inside lining admittedly in the limiting sleeve, when guaranteeing inside lining life, reduces the friction with the piston rod, reduces the wearing and tearing of piston rod, prolongs the life of piston rod, and the practicality promotes greatly.
Preferably, in the above-mentioned novel internal spring stop collar structure, the stop collar is a circular tube structure, and the external diameter of the fitting portion is smaller than the external diameter of the stop portion; adopt this scheme to be convenient for the suit of spring to carry on spacingly through the difference in height of spacing portion and suit portion.
Preferably, in the above novel limiting sleeve structure with an internal spring, the slot on the inner wall of the limiting part is circular; by adopting the scheme, the friction on the piston rod can be reduced better.
Preferably, in the above-mentioned novel structure of the limiting sleeve with an internal spring, the sleeving end of the sleeving part is provided with a chamfer; by adopting the scheme, the end part of the spring can be sleeved in more conveniently, and the installation is more convenient.
Preferably, in the above novel inner spring limit sleeve structure, the inner liner is formed by compounding a polytetrafluoroethylene layer, a steel backing layer and a bronze layer; by adopting the scheme, the friction between the lining and the piston rod is reduced while the strength of the lining is ensured as much as possible, and the service lives of the lining and the piston rod are ensured.
