Abstract
The invention discloses a gas spring with a dustproof device, which relates to the technical field of machinery manufacturing. The gas spring comprises a cylinder body, a piston and a piston rod, the piston rod is connected with the piston and extends out of the cylinder body, the piston rod sequentially passes through a sealing gasket, a gas sealing gasket and a guide sealing ring, a dustproof cover is arranged at the end, out of which the piston rod extends, of the cylinder body, and a dustproof ring is arranged between the dustproof cover and the cylinder body. The invention can solve the problem that at present, since the dustproof devices of gas springs are oversimple, the surfaces of the piston rods can be scratched in the process of using the gas springs, and as a result, the service lives of the gas springs are affected.
Description
Technical field
The present invention relates to machinery manufacturing technology field, especially a kind of air spring with dust guard.
Background technique
Air spring is a kind of industry accessories that can play support, buffering, braking, the highly function such as adjustment and angle adjustment, is widely used in the industries such as automobile, textile manufacturing machine, printing equipment, office equipment, engineering machinery, air spring passes through cylinder body as one, piston rod, hydraulic oil and gas cooperatively interact and carry out the mechanical part of work, various part has higher turbidity test requirement in course of working, also require that environmental conditions is higher in the using process of air spring equally, but due in the using process of most of air spring, the dust of environment, impurity is more, the piston rod of air spring can be attached with a lot of impurity, and current air spring is due to the problem of structure, its dust guard generally all arranges less, after causing air spring to use a period of time, attachment impurity on the piston rod scratches piston rod surface, air spring is caused to leak gas or leakage of oil, air spring is reduced working life greatly.
Summary of the invention
The object of this invention is to provide a kind of air spring with dust guard, it can solve, and current air spring dust guard is too simple, piston rod surface scratches the problem affecting air spring working life in air spring using process.
In order to solve the problem, the technical solution used in the present invention is:
A kind of air spring with dust guard, comprise cylinder body, piston, be connected the piston rod stretching out described cylinder body with piston, described piston rod is successively through sealing gasket, sealing gland pad and pilot seal circle, the piston rod external part of described cylinder body is provided with dust-proof cover, is provided with dust ring between described dust-proof cover and described cylinder body.
In above technological scheme, further scheme can be: described dust-proof cover is the housing of stepped cylindrical shape.
Further: described dust ring is manufactured by polyurethane material.
Owing to have employed technique scheme, the present invention compared with prior art has following beneficial effect:
1, simple, the low cost of manufacture of processing technology of the present invention;
2, the present invention increases dust-proof cover and dust ring outward at air spring cylinder body, and can make the piston rod of air spring before entering cylinder body, remove dust in environment as much as possible, dust-proof piston rod is scratched.
Accompanying drawing explanation
Fig. 1 is plan view of the present invention.
Embodiment
Below in conjunction with drawings and Examples, the present invention is further described:
Embodiment: the air spring of band dust guard as shown in Figure 1, comprise cylinder body 7, piston 8, be connected the piston rod 1 stretching out cylinder body 7 with piston 8, piston rod 1 is successively through sealing gasket 6, sealing gland pad 5 and pilot seal circle 4, on piston 8, radial direction is provided with groove, be axially arranged with aperture and flow into left chamber for hydraulic oil, O RunddichtringO 9 is installed in groove; The external part of the piston rod 1 of cylinder body 7 is provided with dust-proof cover 3, and dust-proof cover 3 is the housing of stepped cylindrical shape, is provided with the dust ring 2 manufactured by polyurethane material between dust-proof cover 3 and cylinder body 7.
