Abstract
The utility model discloses a two pole air springs, including cylinder body, piston and piston rod, the inner chamber of piston and cylinder body slides and is connected, the one end and the piston fixed connection of piston rod, and the other end still includes spacer ring, first sealing washer and two seal covers outside stretching out the cylinder body, piston and piston rod all have two, and stretch into interior intracavity by the both ends of cylinder body respectively, the inner wall of cylinder body is equipped with two archs, and the spacer ring clamps between two archs, and is equipped with first sealing washer between spacer ring and the cylinder body inner wall, all overlapping on two piston rods and being equipped with the seal cover, the one end and the piston of seal cover offset. The utility model discloses the shock -absorbing capacity is good, can accomplish the pressure variation of two kinds of differences, and the usage is extensive.
Description
Technical field
The utility model relates to a kind of two bar air 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.In piston rod movement process, need to arrange oil sealing, traditional air spring all only has a piston and a piston rod, and shock-absorbing capacity is poor.And can only accomplish that a kind of pressure changes, purposes receives restriction.
Summary of the invention
It is good that the purpose of this utility model is to provide a kind of shock-absorbing capacity, can accomplish two kinds of different pressure changes, broad-spectrum pair of bar air spring.
In order to achieve the above object, the technical solution of the utility model is: a kind of two bar air spring, comprise cylinder body, piston and piston rod, piston is connected with the inner chamber slippage of cylinder body, one end of piston rod is fixedly connected with piston, the other end stretches out outside cylinder body, also comprise spacer ring, first seal ring and two stuffing box glands, described piston and piston rod all have two, and stretch in inner chamber by the two ends of cylinder body respectively, the inwall of described cylinder body is provided with two projections, spacer ring is installed between two projections, and between spacer ring and inboard wall of cylinder block, be provided with the first seal ring, described two piston rods are all set with stuffing box gland, one end and the piston of stuffing box gland offset.
Also comprise two piston packings, two piston packings lay respectively at two between piston and cylinder body.
After adopting said structure, the utility model owing to having two pistons and piston rod, and is stretched in inner chamber by the two ends of cylinder body respectively, and two piston rods and piston is separated by spacer ring, and ensures the sealing effect of spacer ring.Therefore two piston rods can realize two kinds of different pressure changes, and of many uses, two piston rods are all set with stuffing box gland, and one end and the piston of stuffing box gland offset, and the sealing effect of guarantee two pistons, shock-absorbing capacity is good.
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 bar air spring, comprise cylinder body 1, piston 2 and piston rod 3, piston 2 is connected with the inner chamber 1-1 slippage of cylinder body 1, one end of piston rod 3 is fixedly connected with piston 2, the other end stretches out outside cylinder body 1, also comprise spacer ring 4, first seal ring 5 and two stuffing box glands 6, described piston 2 and piston rod 3 all have two, and stretch in inner chamber 1-1 by the two ends of cylinder body 1 respectively, the inwall of described cylinder body 1 is provided with two protruding 1-2, spacer ring 4 is installed between two protruding 1-2, and be provided with the first seal ring 5 between spacer ring 4 and cylinder body 1 inwall, described two piston rods 3 are all set with stuffing box gland 6, one end and the piston 2 of stuffing box gland 6 offset.
Shown in Figure 1, in order to improve the sealing effect of two pistons 2 further, also comprising two piston packings, 7, two piston packings 7 and laying respectively between two pistons 2 and cylinder body 1.
Shown in Figure 1, the utility model has two pistons 2 and piston rod 3, and is stretched in inner chamber 1-1 by the two ends of cylinder body 1 respectively, and two piston rods 3 and piston 2 is separated by spacer ring 4, and ensures the sealing effect of spacer ring 4.Therefore two piston rods 3 can realize two kinds of different pressure changes, and of many uses, two piston rods 3 are all set with stuffing box gland 6, and one end and the piston 2 of stuffing box gland 6 offset, and the sealing effect of guarantee two pistons 2, shock-absorbing capacity is good.
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.
