Abstract
The utility model provides a kind of high-end gas spring cold drawing accurate welded still pipe, including steel pipe body and set on the wiper ring of the body open end, the wiper ring is set at the body openings by bearing and is rotatablely connected with the ontology, the wiper ring is fixedly connected with the bearing outer ring, the wiper ring inner wall and air spring piston bar cooperate, circumferentially arranged with muti-piece wiper on the wiper ring inner wall.A kind of high-end gas spring cold drawing accurate welded still pipe provided by the utility model, using wiper ring is arranged in steel pipe body, when piston rod is shunk, wiper ring rotation, wiper cleans piston rod, and structure is simple, guarantees gas spring service life.
Description
Technical field
The utility model relates to steel pipe technical fields, weld steel more particularly to a kind of high-end gas spring cold drawing accurate
Pipe.
Background technique
Gas spring (gas spring) is that one kind can play the functions such as support, buffering, braking, height adjustment and angular adjustment
Industry accessories.It is made of following sections: steel pipe, piston rod, piston, seal guide sleeve, filler (inert gas or
Gas mixture), control element and cylinder outer control element (referring to controllable gas spring) and connector etc. in cylinder.Principle is in closed pressure
Inert gas is filled in power cylinder, and perhaps gas mixture makes the intracorporal pressure of chamber higher than several times or tens times of atmospheric pressure, benefit
Realize the movement of piston rod to the pressure difference generated less than the cross-sectional area of piston with the cross-sectional area of piston rod.
Since the side of piston rod is connect with piston and is mounted in steel pipe, piston rod makees axial reciprocal fortune when work
Dynamic, working condition lower piston rod is exposed to the outside of steel pipe, and external environment is easy pollution piston rod, cause piston rod and steel pipe it
Between seal failure, thus influence gas spring service life.
Utility model content
The technical problem to be solved by the utility model is in order to overcome the shortcomings in the prior art, the utility model mentions
For a kind of high-end gas spring cold drawing accurate welded still pipe.
The utility model solves its technical problem technical solution to be taken: a kind of high-end gas spring cold drawing accurate
Welded still pipe, including steel pipe body and set on the wiper ring of the body open end, the wiper ring is set to institute by bearing
It states and is rotatablely connected at body openings with the ontology, the wiper ring is fixedly connected with the bearing outer ring, in the wiper ring
Wall surface and air spring piston bar cooperate, circumferentially arranged with muti-piece wiper on the wiper ring inner wall.
Ontology is used for loading piston bar and wiper ring, and for connecting with ontology, bearing outer ring is used for and cleaning bearing inner race
Ring connects, and setting wiper and piston rod cooperate on wiper ring inner wall, and when piston rod is shunk, wiper ring rotates, wiper
Piston rod is cleaned.
Further, for the ease of installation, the wiper ring is made of two semi-circular shape cleaning blocks, in order to guarantee piston rod
Cleaning quality, the cleaning block side wall is equipped with through-hole for injecting cleaning solution.It is injected by through-hole in wiper clear
Clean liquid guarantees wiper cleaning quality.
The beneficial effects of the utility model are: a kind of high-end gas spring provided by the utility model welds steel with cold drawing accurate
Pipe, using wiper ring is arranged in steel pipe body, when piston rod is shunk, wiper ring rotation, wiper cleans piston rod,
Structure is simple, guarantees gas spring service life.
Detailed description of the invention
The utility model is described in further detail with reference to the accompanying drawings and examples.
Fig. 1 is the structural schematic diagram of the best embodiment of the utility model；
Fig. 2 is the structural schematic diagram of wiper ring.
In figure: 1, ontology, 2, bearing, 3, wiper ring, 3-1, cleaning block, 4, through-hole, 5, wiper, 6, piston rod.
Specific embodiment
The utility model is described in detail presently in connection with attached drawing.This figure is simplified schematic diagram, only in a schematic way
Illustrate the basic structure of the utility model, therefore it only shows composition related with the utility model.
As shown in Figs. 1-2, a kind of high-end gas spring cold drawing accurate welded still pipe of the utility model, including steel pipe body
1 and the wiper ring 3 set on 1 open end of ontology, the wiper ring 3 is set to 1 opening of ontology and institute by bearing 2
The rotation connection of ontology 1 is stated, the wiper ring 3 passes through threaded hole by bolt and is fixedly connected with 2 outer ring of bearing, the cleaning
3 inner wall of ring and air spring piston bar 6 cooperate, circumferentially arranged with muti-piece wiper 5 on 3 inner wall of wiper ring.
The wiper ring 3 is fixedly connected by bolt across threaded hole by two semi-circular shape cleaning block 3-1, the cleaning
Block 3-1 side wall is equipped with the through-hole 4 for injecting cleaning solution.
It is enlightenment, through the above description, relevant work with the above-mentioned desirable embodiment according to the utility model
Personnel can carry out various changes and amendments in without departing from the scope of the utility model completely.This item utility model
Technical scope is not limited to the contents of the specification, it is necessary to which the technical scope thereof is determined according to the scope of the claim.
