Description
Technical field
The utility model relates to steel pipe technical fields, more particularly to a kind of gas spring cold drawing accurate welded still 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：Sleeve, 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 set
Inert gas is filled in cylinder, and perhaps gas mixture makes the intracorporal pressure of chamber higher than several times or tens times of atmospheric pressure, utilizes
The cross-sectional area of piston rod realizes the movement of piston rod less than the cross-sectional area of piston to the pressure difference generated.
Sleeve is during transportation, large number of, and slight deformation can be occurred between each other by squeezing mutually, although naked eyes are different
That observes surely comes out, but affects the precision of sleeve, and large error occurs in the fitness of sleeve and piston space, influences gas bullet
The performance of spring and the service life of gas spring.
Utility model content
Technical problem to be solved in the utility model is：Hair is easy in prior art middle sleeve transportational process in order to overcome
The deficiency for the shape that changes, the utility model provide a kind of gas spring cold drawing accurate welded still pipe.
The utility model solves its technical problem technical solution to be taken：A kind of gas spring is welded with cold drawing accurate
Steel pipe, air bag and gas tube including steel pipe body and on the ontology, the ontology is interior to be equipped with cavity, the ontology
Along air inlet is axially arranged with, the air inlet is connected to the cavity for one end, and the ontology is covered far from the side of the air inlet
Equipped with the air bag cooperated with gas spring sleeve lining face, offered on the side wall that the ontology cooperates with the air bag multiple
The through-hole being connected to the cavity, the gas tube be equipped with aeration aperture, the gas tube be sheathed on described body sidewall with
The ontology is slidably connected, and edge is axially arranged with the cylindricality blocking for being used to open or closing the air inlet in the gas tube.
For being inserted into gas spring sleeve, through-hole is used to be connected to by cavity with air inlet ontology, so as to air bag
Interior injection gas props up air bag, and air bag can prevent gas spring in the deflated condition fully supporting gas spring sleeve inner
Sleeve is squeezed deforms during transportation, and gas tube is used to connect by aeration aperture with external inflation equipment, by filling
Stomata is connected to air inlet and inflates into air bag, blocks for the band after air bag fully supports gas spring sleeve inner in gas tube
Dynamic lower closing air inlet, prevents air bag gas leakage, guarantees protective effect of the air bag to gas spring sleeve.
Further, gas tube and the gas leakage of ontology coupling part in order to prevent is arranged at intervals on the gas tube inner wall
Multiple ring type seals.
The utility model has the beneficial effects that：A kind of gas spring cold drawing accurate welded still pipe provided by the utility model,
Using air bag is arranged on ontology, air bag in the deflated condition fully supports gas spring sleeve inner, can prevent gas spring sleeve from existing
It is squeezed and deforms in transportational process.
Detailed description of the invention

Fig. 2 is the working state schematic representation of the best embodiment of the utility model.
In figure：1, ontology, 2, air bag, 3, gas tube, 4, cavity, 5, air inlet, 6, through-hole, 7, aeration aperture, 8, blocking.
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 gas spring cold drawing accurate welded still pipe of the utility model, including steel pipe body 1 with
And air bag 2 and gas tube 3 on the ontology 1, the ontology 1 is interior to be equipped with cavity 4, and described 1 one end of ontology is set along axial direction
There is air inlet 5, the air inlet 5 is connected to the cavity 4, and the ontology 1 is arranged with far from the side of the air inlet 5 and gas
Multiple and institute is offered on the air bag 2 of spring spool inner wall cooperation, the ontology 1 and the side wall of the air bag 2 cooperation
The through-hole 6 of the connection of cavity 4 is stated, the gas tube 3 is equipped with aeration aperture 7, and the gas tube 3 is sheathed on 1 side wall of ontology
It is slidably connected with the ontology 1, it is stifled along the cylindricality that is used to open or closes the air inlet 5 is axially arranged in the gas tube 3
Plug 8, the blocking 8 use rubber material.
Three ring type seals are arranged at intervals on 3 inner wall of gas tube.
The course of work：
Ontology 1 is inserted into gas spring sleeve, under 5 opening state of air inlet, is connect by air pump with aeration aperture 7, it is right
Gas tube 3 is slided to 1 direction of ontology after air bag 2 fully supports gas spring sleeve inner, inserts blocking 8 by inflation in air bag 2
Enter and close air inlet 5 in air inlet 5, then disconnect the connection between air pump and aeration aperture 7, completes installation.
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.
