Part 22 is fixed, facilitates the fixation of armrest cover 3, is also beneficial to the carrying of handrail.
Further, a kind of specific embodiment party also referring to Fig. 1 to Fig. 5, as armrest mechanism provided by the invention
Formula, lifting assembly 1 include air pressure rod 11, and air pressure rod 11 is opened including piston 112, piston rod 113, the first return component 115, gas circuit
116 and closed shell 111 are closed, the sealing of piston 112 is slidedly arranged in shell 111；Piston rod 113 is fixedly arranged on piston 112 and one
End stretches out in outside shell 111, and sealing is slidedly arranged on shell 111；Shell 111 is connected between the chamber of 112 two sides of piston
Gas circuit 114, and gas circuit 114 is equipped with air circuit breaker 116；Air circuit breaker 116 reaches outside shell 111；First return component 115
One end and shell 111 it is fixed, the other end and air circuit breaker 116 are fixed；First return component 115 is for driving air circuit breaker
116 are repositioned to the closed state of gas circuit 114.
In use, filled with high pressure gas, preferably high pressure nitrogen in the sealed internal chamber of shell 111, when being highly not required to adjust,
First return component 115 drives air circuit breaker 116 to be repositioned to the closed state of gas circuit 114, and the chamber of 112 two sides of piston does not connect
Logical, the chamber away from 113 side of piston rod of piston 112 is in full closeding state, forms closed air cavity, the air pressure of closed air cavity
Pressure of the pressure balance from armrest cover 3 carries convenient for air pressure rod 11.
When needing to adjust height, applies external force and squeeze air circuit breaker 116, external force overcomes returning for the first return component 115
Position power and drive air circuit breaker 116 mobile, release the closing to gas circuit 114, the chamber of 112 two sides of piston, 112 liang of piston
The air pressure of side is identical；It is less than the compression away from 113 side of piston rod due to the compression area of 113 side of piston rod of piston 112
Area, piston 112 and the sliding of 113 opposite shell 111 of piston rod, extend air pressure rod 11, and the height of handrail increases；Or apply
Pressed by external force shell 111 shortens air pressure rod 11, reduces the height of handrail；It unclamps when adjusting and arriving appropriate height to air circuit breaker
116 extruding, baroswitch self-return under the action of the first return component 115 close gas circuit 114, and handrail returns to static shape
