Abstract

The utility model discloses a double-rod hydraulic damper which comprises a cylinder, a shell component, a piston rod and a piston arranged at one end of the piston rod, wherein the shell component is sheathed on the cylinder; the piston on the piston rod is arranged in the cylinder to divide the cylinder into two chambers; a first lining and a second lining are respectively fixed at two sides of the piston in the cylinder; a medium is filled in the cylinder; the other end of the piston rod passes through the first lining and the shell component to be fixedly connected with a connector; a second piston rod is also fixedly connected on the piston and passes through the second lining; and a medium channel is arranged on the piston. The double-rod hydraulic damper is convenient for size adjustment and reliable to use.

Description

Two bar hydraulic dampers
Technical field
The utility model relates to a kind of pair of bar hydraulic damper.
Background technique
Damper is that the interaction of using resisting medium and damper structure parts produces a kind of passive velocity correlation type product of the principle design making of damping force.
At present, existing damper mostly adopts service tank to realize the damper adjusting oil mass between two chambeies up and down, therefore many oil ducts need be set and need to use a large amount of Sealings, to reach the purpose that can not leak, and Sealing is an easily damaged parts, be easy to damage, will cause problem safe in utilization like this.
Summary of the invention
The purpose of this utility model is to provide a kind of service-strong two bar hydraulic dampers.
In order to achieve the above object, the technical solution of the utility model is: a kind of pair of bar hydraulic damper, comprise cylinder body, frame set, piston rod and the piston that is contained in piston rod one end, described frame set is sleeved on the cylinder body, piston on the piston rod is installed in the cylinder body and cylinder body is divided into two chambers, be installed with first lining and second lining respectively in the both sides of piston in the described cylinder body, be marked with medium in the cylinder body, the other end of piston rod passes first lining fixedlys connected with link with frame set, also be fixedly connected with second piston rod on the described piston, second piston rod passes second lining; And has medium channel on the piston.
Be fixedly connected with the regulating lever assembly on the described cylinder body.
Between described first lining and the piston rod, and be equipped with Sealing between second lining and second piston rod.
After adopting said structure, also be fixedly connected with second piston rod on the described piston, second piston rod passes second lining; And have medium channel on the piston, can be so that realize the medium intercommunication between two chambers that are divided into by piston in the cylinder body, thus form damping, do not need to re-use assist medium container and passage, reduced the use seal ring, safe in utilization stable.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
The embodiment who provides below in conjunction with accompanying drawing is described in further detail the utility model.
As shown in Figure 1, a kind of pair of bar hydraulic damper of the present utility model, comprise cylinder body 1, frame set 3, piston rod 4 and the piston 8 that is contained in piston rod 4 one ends, described frame set 3 is sleeved on the cylinder body 1, piston 8 on the piston rod 4 is installed in the cylinder body 1 and cylinder body 1 is divided into two chambers, be installed with first lining 5 and second lining 9 in the described cylinder body 1 respectively in the both sides of piston 8, be marked with oil in the cylinder body 1 as medium 7, the other end of piston rod 4 passes first lining 5 fixedlys connected with link with frame set 3, also be fixedly connected with second piston rod, 10, the second piston rods 10 on the described piston 8 and pass second lining 9; And has medium channel 8-1 on the piston 8.
As shown in Figure 1, for the ease of adjusting the length of damper, be fixedly connected with regulating lever assembly 2 on the described cylinder body 1.
As shown in Figure 1, in order to guarantee sealing, between described first lining 5 and the piston rod 4, and be equipped with Sealing 6 between second lining 9 and second piston rod 10.
The piston rod 4 described in the utility model and second piston rod 10 can be two sections, also can be the structures of one.
