Put, solve the defect that conventional damping device is complicated, ponding is difficult discharge.
The technical solution adopted for the present invention to solve the technical problems is：A kind of damping device with leaking hole, including cylinder
Piston is set in body, described cylinder body, cylinder body is divided into the first working chamber and the second working chamber, described first by described piston
First compression spring is set in working chamber, and the described cylinder base being located in the first working chamber is provided with leaking hole, described
Sealing ring is provided with the side wall of piston, described piston and cylinder side wall is mutually in sealing contact,
The piston rod being mutually integrally formed with piston is provided with the second described working chamber, described upper cover of piston rod is connected to
Piston rod offsets is provided with external sleeve, described external sleeve and cylinder body phase sliding contact, described external sleeve
Two compression springs.
Further, described piston is structure as a whole with piston rod.
The beneficial effects of the invention are as follows：A kind of damping device with leaking hole is provided, it is living by setting piston in cylinder body
The first compression spring is set between plug and cylinder bottom, piston rod is set on piston, upper cover of piston rod connects external sleeve, piston rod with
Second compression spring is set between external sleeve, by the effect of two springs, damping effect is improved, and in the bottom of cylinder body
Leaking hole in setting, the ponding in discharge cylinder body, extends the service life of cylinder body in time.
Brief description of the drawings
The present invention is further described below in conjunction with the accompanying drawings.
Fig. 1 is the structural representation of damping device；
Wherein：1st, cylinder body, 2, piston, 3, external sleeve, 4, sealing ring, 5, leaking hole.
Embodiment

The bottom of cylinder body 1 for making intracavitary is provided with leaking hole 5, and sealing ring 4, piston 2 and cylinder body 1 are provided with the side wall of described piston 2
Side wall is mutually in sealing contact,
The piston rod being mutually integrally formed with piston 2 is provided with second working chamber, upper cover of piston rod is connected to external sleeve 3,
The second compression spring that piston rod offsets is provided with external sleeve 3 and the phase sliding contact of cylinder body 1, external sleeve 3.Piston 2 with
Piston rod is structure as a whole.
By setting piston 2 in cylinder body 1, the first compression spring is set between piston 2 and cylinder bottom 1, set on the piston 2
Piston rod, upper cover of piston rod connects external sleeve 3, and the second compression spring is set between piston rod and external sleeve 3, passes through two bullets
The effect of spring, improves damping effect, and sets leaking hole 5 in the bottom of cylinder body 1, and the ponding in discharge cylinder body 1, prolongs in time
The service life of long cylinder body 1.
Using the above-mentioned desirable embodiment according to the present invention as enlightenment, by above-mentioned description, relevant staff is complete
Various changes and amendments can be carried out without departing from the scope of the technological thought of the present invention' entirely.The technology of this invention
Property scope is not limited to the content on specification, it is necessary to its technical scope is determined according to right.
