It is equipped with large washer, the rubber pad for sealing is provided on the large washer；It is set between the large washer bottom and junior's cylinder
It is equipped with the triangle muscle for further consolidating large washer.
Further, it is provided with shell flange above junior's cylinder to be fixedly connected with metal ring, the cylinder method
Orchid is detachably connected by bolt device and the formation of junior's cylinder.
Further, the metal ring lower part is provided with sealing inclined-plane, and the inclined direction of sealing inclined-plane be by interior and
Outside and obliquely；The rubber pad outer radii size is greater than large washer outer radii size.
Further, the metal ring upper inner is provided with the rubber ring for limit.
The utility model has the beneficial effects that
1, utility model device metal ring and rubber pad are equipped with, after lifting tube rises when realizing work on
The rubber pad of grade cylinder and the metal ring of junior's cylinder press together, and realize sealing, will not additionally increase frictional force, seal
Reliably.
2, metal ring is movably arranged on junior's cylinder by the setting of utility model device middle cylinder body flange and bolt device
Internal side, convenient for metal ring dismounting and the separation maintenance of upper lower shell；Further, it is also more convenient for present apparatus sealing structural component
Replacement and adjustment.
3, metal ring lower part is arranged in the utility model sealing inclined-plane and outer ring size are greater than the rubber pad of large washer,
It can avoid to a certain extent when being sealed, rubber pad realizes rubber by shear extrusion and the case where serious wear
Pad depends on inclined-plane and gradually seals upwards, while guaranteeing sealing effect, increases the service life of sealing structural component.

Specific embodiment
In order to enable those skilled in the art to better understand the technical solutions of the present invention, with reference to the accompanying drawing to this reality
Be described in detail with novel, the description of this part be only it is exemplary and explanatory, should not be to the protection scope of the utility model
There is any restriction effect.
As shown in figs 1 to 6, the specific structure of the utility model are as follows: a kind of multistage lifting cylinder sealing structure, it includes setting
The multistage lifting cylinder 1 on car body 2 is set, the multistage lifting cylinder 1 includes higher level's cylinder 3 and is cased under 3 lower section of higher level's cylinder
Grade cylinder 4；4 upper inner of junior's cylinder is provided with metal ring 6；3 lower outside of higher level's cylinder is in metal ring 6
Lower section is provided with large washer 7, and the rubber pad 8 for sealing is provided on the large washer 7；7 bottom of large washer and junior
The triangle muscle 9 for further consolidating large washer 7 is provided between cylinder 4.
For the ease of the dismounting of upper lower shell and the adjustment replacement of metal ring, cylinder is provided with above junior's cylinder 4
Body flange 5 is fixedly connected with metal ring 6, and the shell flange 5, which is formed by bolt device 12 with junior cylinder 4, detachably to be connected
It connects.
For the abrasion condition being further reduced in rubber pad use process, 6 lower part of metal ring is provided with sealing
Inclined-plane 11, and the inclined direction of sealing inclined-plane 11 is from inside to outside and obliquely；The 8 outer radii size of rubber pad is greater than big
