Abstract
The utility model relates to a compressed gas spring which comprises a cylinder body (4), a piston arranged in the cylinder body (4) and a piston rod (1), wherein the piston rod is connected with the piston, and one end of the piston rod penetrates out of the cylinder body (4); the cylinder body (4) is in sealed connection with the piston rod (1), and the front end of the piston rod (1) is fixedly connected with a cylinder-shaped protecting cap (2). The compressed gas spring is characterized in that one end of the cylinder body (4) close to the piston rod (1) is fixedly connected with a thin jacket (2); the opening of the cylinder-shaped protecting cap (2) is sleeved on the thin jacket (3); and when making axial movement, the piston rod (1) drives the cylinder-shaped protecting cap (2) to move along the periphery of the cylinder body (4). The utility model can avoid the problem that the piston rod is damaged or polluted during the process of assembly, coating, use, and the like, and the surface of the cylinder body is worn down.
Description
Technical field
The utility model relates to a kind of auto parts machinery field that belongs to.
Background technique
When the piston rod of present pressurized gas spring is not worked, outside being exposed to basically, therefore impaired or contaminated easily in assembling, coating process; In use, also have contamination adhesion on piston rod.Above-mentioned situation, can influence the pressurized gas spring functional reliability, influence working life of pressurized gas spring when serious.For addressing these problems, the people is arranged at fixedly connected tubular guard shield of the front end of piston rod, simple shape guard shield opening end is sleeved on the cylinder body, but such problem that has caused tubular guard shield wearing and tearing cylinder surface influences its outward appearance and life-span.
Summary of the invention
Technical problem to be solved in the utility model is: at the problems referred to above, design a kind of tubular guard shield and thin type sheath of having, can avoid piston rod impaired or contaminated and can not cause the frayed pressurized gas spring of cylinder surface in processes such as assembling, application and use.
The technical solution of the utility model is, a kind of pressurized gas spring, comprise cylinder body, be arranged on the piston in the cylinder body, be connected with piston and an end passes the piston rod of cylinder body, cylinder body is connected with rod seal, the front end of piston rod is fixedly connected with the tubular guard shield, it is characterized in that: on cylinder body one end close, be fixedly connected with the thin type sheath with piston rod, and tubular guard shield opening end is sleeved on the thin type sheath, piston rod drives the tubular guard shield and moves along the outer circumferential face of cylinder body when moving axially, thin type sheath has wherein played the effect of avoiding cylinder surface to be subjected to the wearing and tearing of tubular guard shield.
The utility model can avoid piston rod impaired or contaminated and can not cause the frayed problem of cylinder surface in processes such as assembling, application and use.
