Abstract
The utility model discloses a two -way gas spring, including cylinder body, piston and piston rod, the inner chamber of piston and cylinder body slides and is connected, and piston rod and piston fixed connection still include two jump rings and two sealing washers, the both ends of cylinder body all have the hole of stretching into, and the piston rod passes and stretches into the hole, and the piston links with the middle part dress of piston rod to clamp through two jump rings and piston rod, two sealing washers lie in the intracavity respectively, and the suit is on the piston rod, and lie in respectively and stretch into hole department, all be full of oily medium between sealing washer and the piston. The utility model discloses the damping is effectual, and the usage is extensive.
Description
Technical field
The utility model relates to a kind of two-way gas spring.
Background technique
Air spring purposes widely, the working principle of air spring is filled with inert gas or gas mixture in airtight pressure cylinder, make the pressure in cavity higher than atmospheric manyfold, utilize the cross-section area of piston rod be less than piston cross-section area thus produce pressure difference to realize the motion of piston rod.One end of the piston rod of traditional air spring is stretched in cylinder body, and the other end connects piston, and this structure piston damping is poor, and purposes is extensive not.
Summary of the invention
It is good that the purpose of this utility model is to provide a kind of damping, broad-spectrum two-way gas spring.
In order to achieve the above object, the technical solution of the utility model is: a kind of two-way gas spring, comprise cylinder body, piston and piston rod, piston is connected with the inner chamber slippage of cylinder body, piston rod is fixedly connected with piston, also comprise two jump rings and two seal rings, the two ends of described cylinder body all have stretches into hole, piston rod is through stretching into hole, the middle part load of piston and piston rod, and clamped by two jump rings and piston rod, two seal rings lay respectively in inner chamber, and suit on the piston rod, and lay respectively at and stretch into hole place, oily medium is all full of between described seal ring and piston.
Also comprise piston packing, piston packing is between piston and cylinder body.
After adopting said structure, the utility model stretches into hole because piston rod has run through, piston is arranged in the middle part of piston rod by two jump rings, oily medium is all full of between seal ring and piston, therefore the two ends of piston rod all can be connected with damping object, inner chamber is divided into two cavitys being full of oily medium by piston, and therefore damping is good, of many uses.
Accompanying drawing explanation
Fig. 1 is structure sectional view of the present utility model.
Embodiment
The embodiment provided below in conjunction with accompanying drawing is described in further detail the utility model.
Shown in Figure 1, a kind of two-way gas spring, comprise cylinder body 1, piston 2 and piston rod 3, piston 2 is connected with inner chamber 11 slippage of cylinder body 1, piston rod 3 is fixedly connected with piston 2, also comprise two jump rings 4 and two seal rings 5, the two ends of described cylinder body 1 all have stretches into hole 12, piston rod 3 is through stretching into hole 12, the middle part load of piston 2 and piston rod 3, and clamped by two jump rings 4 and piston rod 3, two seal rings 5 lay respectively in inner chamber 11, and be sleeved on piston rod 3, and lay respectively at and stretch into hole 12 place, oily medium 7 is all full of between described seal ring 5 and piston 2.
Shown in Figure 1, in order to improve the sealing effect of piston 2 further, also comprise piston packing 6, piston packing 6 is between two pistons 2 and cylinder body 1.
Shown in Figure 1, the utility model stretches into hole 12 because piston rod 3 has run through, piston 2 is arranged in the middle part of piston rod 3 by two jump rings 4, oily medium 7 is all full of between seal ring 5 and piston 2, therefore the two ends of piston rod 3 all can be connected with damping object, inner chamber 11 is divided into two cavitys being full of oily medium 7 by piston 2, and therefore damping is good, of many uses.
Above-described is only preferred implementation of the present utility model; it should be pointed out that for the person of ordinary skill of the art, under the prerequisite not departing from the utility model creation design; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
