Stent periphery and outer tube wall sealing are connected, and piston is fixedly mounted on the upper end of stent, and control valve is fixed at inner tube
Upper port on, control valve periphery and outer tube wall sealing be connected, bar air cavity is formed between outer tube lower end and stent, prop up
The connecting hole for being provided on frame and having bar air cavity to be connected is formed between piston, inner tube and control valve without bar oil pocket, the medium
Floating piston is additionally provided in flow cavity, is formed between floating piston, control valve, outer tube and inner tube and flows oil pocket, floating piston,
Flowing air cavity is formed between stent, outer tube and inner tube, flowing oil pocket does not connect mutually with flowing air cavity, and energy is provided on control valve
The switch button whether enough control connects without bar oil pocket with flowing oil pocket, the connecting hole are connected with flowing air cavity.
The beneficial effects of the utility model are the nonelastic gas springs of the utility model, between the inner and outer pipe sections between
Floating piston is additionally arranged in gap, the top of chamber where rodless cavity and floating piston is full of fluid, rod chamber and floating piston
The lower part gassy of place chamber, after atmospheric pressure pole regulates height, oil liquid resistance is big, the range very little compressed, therefore
Floating up and down for atmospheric pressure pole can be avoided, improves the stability of atmospheric pressure pole.
Description of the drawings
The utility model is further illustrated with reference to the accompanying drawings and examples.
Fig. 1 is the structure diagram of the utility model optimum embodiment.
In figure：1st, vertical tube, 2, outer tube, 3, inner tube, 4, piston, 5, piston rod, 6, control valve, 7, media flow chamber, 8, branch
Frame, 9, have a bar air cavity, 10, without bar oil pocket, 11, switch button, 12, floating piston, 13, flowing oil pocket, 14, flowing air cavity.
Specific embodiment
The utility model is described in further detail presently in connection with attached drawing.These attached drawings are simplified schematic diagram,
Only illustrate the basic structure of the utility model in a schematic way, therefore it only shows the composition related with the utility model.
As shown in Figure 1, be the utility model optimum embodiment, a kind of nonelastic gas spring, the tubular including upper end opening
Vertical tube 1, outer tube 2, inner tube 3, piston 4, piston rod 5 and control valve 6, the lower end of piston rod 5 are fixed at the bottom in vertical tube 1
Portion, piston 4 are arranged on the upper end of piston rod 5, and inner tube 3 is sleeved on piston 4, and outer tube 2 is sleeved in inner tube 3, outer tube 2 and inner tube
Gap between 3 forms media flow chamber 7, and vertical tube 1 is sleeved on outer tube 2, and outer tube 2 can slide up and down in vertical tube 1, and outer
It is tightly connected between the lower end of pipe 2 and piston rod 5, the lower end of inner tube 3 is located in outer tube 2, and the lower port of inner tube 3 is provided with stent
8,8 periphery of stent and 2 inner wall sealing of outer tube are connected, and piston 4 is fixedly mounted on the upper end of stent 8, and control valve 6 is fixedly installed
In the upper port of inner tube 3,6 periphery of control valve and 2 inner wall sealing of outer tube are connected, and are formed between 2 lower end of outer tube and stent 8
Have bar air cavity 9, be provided on stent 8 with the connecting hole that there is bar air cavity 9 to be connected, formed between piston 4, inner tube 3 and control valve 6
Without bar oil pocket 10, be additionally provided with floating piston 12 in media flow chamber 7, floating piston 12, control valve 6, outer tube 2 and inner tube 3 it
Between formed flowing oil pocket 13, between floating piston 12, stent 8, outer tube 2 and inner tube 3 formed flowing air cavity 14, flow 13 He of oil pocket
Flowing air cavity 14 does not connect mutually, and no bar oil pocket 10 can be controlled and flow what whether oil pocket 13 connected by being provided on control valve 6
Switch button 11, connecting hole are connected with flowing air cavity 14.
The course of work：Switch button 11 is not opened, and is not connected between no bar oil pocket 10 and media flow chamber 7, then atmospheric pressure pole
It can not rise or fall.
