Abstract
The utility model discloses a jack guide structure of brazing solder, including hydro -cylinder, piston rod and piston, the piston includes first portion and second portion, the first portion is as an organic whole with the second portion, first portion outside cover is equipped with the sealing washer, the second portion outside is equipped with copper ring, be equipped with the retaining ring between sealing washer and the copper ring. This guide structure working property is good, and simple structure is with low costs, and the hydro -cylinder inner wall is not fragile, has longer life.
Description
Technical field
The utility model is related to a kind of jack structure, specifically refers to a kind of jack guide frame of bit copper.
Background technology
At present, all using steel matter, after Long-Time Service, oil cylinder inner wall is easily bad by shovel for traditional jack guide frame,
Lead to jack cannot be continuing with, relatively costly.
Utility model content
The purpose of this utility model is to provide for a kind of jack guide frame of bit copper, this guide frame service behaviour
Good, structure is simple, low cost, and oil cylinder inner wall is hardly damaged, and has longer service life.
In order to achieve the above object, the utility model provides following technical scheme：A kind of jack guiding knot of bit copper
Structure, including oil cylinder, piston rod and piston, described piston includes Part I and Part II, described Part I and second
Be divided into one, outside described Part I, be arranged with sealing ring, outside described Part II, be provided with copper band, described sealing ring with
It is provided with back-up ring between copper band.
It is further preferred that described copper band is welded on Part II.
It is further preferred that the section of described piston is convex structure.
The beneficial effects of the utility model：This guide frame favorable working performance, structure is simple, low cost, and oil cylinder inner wall
It is hardly damaged, there is longer service life.

Accompanying drawing 1 is structural representation of the present utility model.
Marginal data：1st, oil cylinder；2nd, piston rod；3rd, piston；4th, sealing ring；5th, copper band；6th, back-up ring；31st, Part I；
32nd, Part II.
Specific embodiment
We combine accompanying drawing and a kind of jack guide frame of bit copper described in the utility model are done further below
Explanation.
As shown in fig. 1, the jack guide frame of a kind of bit copper of the present embodiment, including oil cylinder 1, piston rod 2 and work
Plug 3, described piston 3 includes Part I 31 and Part II 32, and described Part I 31 and Part II 32 are integrated, institute
State and outside Part I 31, be arranged with sealing ring 4, outside described Part II 32, be provided with copper band 5, described sealing ring 4 and copper band 5
Between be provided with back-up ring 6.Described copper band 5 is welded on Part II 32.The section of described piston 3 is convex structure.In oil cylinder 1
Welding copper band 5 in guiding position, so that the inwall of oil cylinder 1 is hardly damaged, because copper band 5 is welding, is less prone to the feelings coming off
Condition is it is ensured that service behaviour.Copper band 5 is just welded before piston 3 is processed, and finishes, it is to avoid secondary operation together with piston 3 part
Error is it is ensured that form and position tolerance and dimensional tolerance.
Protection domain of the present utility model is not limited to above example and its conversion.
