Description
Technical field
This utility model relates to gas spring technology field, especially relates to a kind of cleaning type air spring.
Background technology
Air spring be a kind of can rise support, buffer, brake, the work of the function such as altitude mixture control and angular adjustment
Industry accessory.Principle is to be filled with noble gas or gas mixture in airtight pressure cylinder, in making cavity
Several times of pressure superatmospheric or tens times, utilize the cross-sectional area cross section less than piston of piston rod
The pressure differential amassed thus produce is to realize the motion of piston rod.
Air spring in existing use, in its piston rod one end insertion pressure cylinder, the other end is exposed outside,
Such structure has the disadvantage in that exposed piston rod can not be protected, and has more at some
In the production environment of dust, exposed piston rod is very easy to long-pending full dust, and surface is stained with dust
Piston rod can frequently and seal guide sleeve friction, the friction system owing to there being the existence of dust, in friction process
Number is big, is easily caused piston rod and seal guide sleeve damages, so needing often to check and keep in repair, during maintenance,
Also to carry out after being dismantled by pressure cylinder, maintenance bothers very much, and decreases the service life of air spring.
Utility model content
The technical problems to be solved in the utility model is: in order to solve the exposed piston rod of existing air spring
Can not be protected, in some have the production environment of more dust, exposed piston rod holds very much
The problem of the most long-pending full dust, now provides a kind of cleaning type air spring.
This utility model solves its technical problem and be the technical scheme is that a kind of cleaning type air spring, bag
Including cylinder body and be slidably arranged in the piston rod of cylinder body one end, described cylinder body is positioned at one end of piston rod and is provided with air inlet
Road, offers annular groove, is provided with in described annular groove between described cylinder body and described plunger rod contacts face
Some drainage plates, described air intake duct connects with described annular groove, offers annular chamber in described cylinder side wall
Body, described annular groove connects with described annular housing, and described cylinder body is provided with gas off-take, described gas off-take
Connecting with described annular housing, by accessing gases at high pressure at air intake duct, gases at high pressure are at the water conservancy diversion of drainage plate
To piston rod dedusting under effect, dust is discharged by gas off-take through annular housing, on the one hand can be to piston rod
Being cleaned, on the other hand gas enters toroidal cavity, cylinder body can be had cooling effect.
In order to make air spring have good sealing, further, described cylinder body and described plunger rod contacts
It is positioned at annular groove both sides between face and is equipped with sealing ring, owing to being positioned at ring between cylinder body and plunger rod contacts face
Connected in star both sides are equipped with sealing ring, it is ensured that the sealing property that air spring is good when being passed through gas and running.
Flow along a direction to enable to be passed through gas, simultaneously can be preferably to piston rod surface powder
The cleaning of dirt, further, described drainage plate is positioned at described annular groove and is distributed in the shape of a spiral, owing to drawing
Stream plate is positioned at annular groove and is distributed in the shape of a spiral, and making to be passed through gas can flow in one direction, the most right
Dust on piston rod is cleaned.
The beneficial effects of the utility model are: this utility model cleaning type air spring in use, by entering
Air flue accesses gases at high pressure, and gases at high pressure are to piston rod dedusting under the guide functions of drainage plate, and dust passes through
Annular housing is discharged by gas off-take, on the one hand can be cleaned piston rod, and on the other hand gas enters annular
Cavity, can have cooling effect to cylinder body；Owing to being positioned at annular groove two between cylinder body and plunger rod contacts face
Side is equipped with sealing ring, it is ensured that the sealing property that air spring is good when being passed through gas and running；Due to drain
Plate is positioned at annular groove and is distributed in the shape of a spiral, makes to be passed through gas and can flow in one direction, simultaneously to work
Dust on stopper rod is cleaned；This utility model has good cleaning capacity, has cylinder body good simultaneously
Good cooling effect, its simple in construction, it is ensured that air spring is stable and reliable in work.
