2nd, contraction speed is uncontrollable, so the too fast problem of contraction speed occurs using in；
3rd, piston one end is directly communicated with air, non air exit hole device, so piston rod contraction speed is quickly, without buffering
Damping effect, occurs the problems such as significant shock, impact, needs additionally to increase other devices and enter row buffering in use.
The content of the invention
To solve the deficiencies in the prior art, it is an object of the invention to provide a kind of power output is steady, force variation is little, receipts
Contracting speed is controllable, the preferable pulling force gas spring of buffering and damping effect.
In order to realize above-mentioned target, the present invention is adopted the following technical scheme that：
The pulling force gas spring that a kind of power output is steady, force variation is little, including：Cylinder barrel, piston rod (1), guide ring (2),
Sealing ring (3) and piston (9), aforementioned guide ring (2) and sealing ring (3) are arranged on the front end of cylinder barrel, and piston rod (1) is from guide ring
(2) and in sealing ring (3) sequentially pass through, inner end of the piston (9) installed in piston rod (1), it is characterised in that also include：Back-up ring
(4) and tail stifled (11),
Aforementioned cylinder barrel is double-decker, is made up of inner core (6) and outer tube (7), and inner core is each filled with high pressure inside and outside (6)
Nitrogen (8), aforementioned back-up ring (4) and tail stifled (11) are separately positioned on the rear and front end of inner core (6), wherein, back-up ring is formed with (4)
Air flue (5), by air flue (5) the cavity insertion surrounded by the interlayer of cylinder barrel and sealing ring (3), tail block up (11) row of being axially formed
Pore (13), steam vent (13) cause one end of piston (9) to communicate with air.
The pulling force gas spring that aforesaid power output is steady, force variation is little, it is characterised in that aforementioned piston (9) and inner core
(6) O-ring (10) is provided between inwall.
The pulling force gas spring that aforesaid power output is steady, force variation is little, it is characterised in that said o circle (10) is arranged
There are two.
The pulling force gas spring that aforesaid power output is steady, force variation is little, it is characterised in that aforementioned tail blocks up (11) and inner core
(6) O-ring (12) is provided between inwall and the inwall of outer tube (7).
The pulling force gas spring that aforesaid power output is steady, force variation is little, it is characterised in that aforementioned tail blocks up (11) and inner core
(6) two O-rings (12) are provided between inwall, two O-rings (12) is also equipped with and the inwall of outer tube (7) between.
The invention has benefit that：
(1) cylinder barrel is designed to into double-decker, makes in gas spring cylinder barrel, have larger gas initial volume, when piston rod is received
During contracting, the change in volume of air chamber is far smaller than gas initial volume, therefore the pressure change of gas is with regard to very little, the elastic force of gas spring
, with regard to very little, power output is steady for rate of change；
(2) tail is stifled has been axially formed steam vent, and the air when piston rod shrinks in cylinder barrel is pressurized and passes through steam vent
Discharge, by the size for changing steam vent, can control the velocity of discharge of inner air, the contraction speed of piston rod accordingly changes,
And pooling feature can be provided.
