Summary of the invention
In order to solve the above-mentioned technical problems, the present invention provides a kind of rigid self-locking gas springs of air bag outside low pressure.
The technical solution adopted by the present invention is that: a kind of outer air bag rigidly self-locking gas spring, including starting bar of low pressure, piston Bar, piston, needle-valve, cylinder barrel, guide sleeve, straight outside framework oil seal, separation sleeve, air bag, tail be stifled, steel needle;One end of the cylinder barrel is by tail The sealing of stifled and steel needle, the other end install piston;The piston and piston rod are connected, between piston rod and cylinder barrel from inside to outside successively Separation sleeve, straight outside framework oil seal and guide sleeve are set;Sliding fit is connected with needle-valve in the piston, and the center that needle-valve passes through piston is stretched Enter to piston rod;The piston rod is hollow rod body, and inside is equipped with starting bar, and starting bar corresponds to needle-valve setting;The cylinder Hydraulic oil is filled in cylinder, tail end is equipped with external air bag, and air bag is connect by high-voltage tube with cylinder barrel, installs on pipeline unidirectional Valve is filled with inert gas in air bag.
The cylinder barrel, piston rod port be respectively provided with closing in.
The contact position of the needle-valve and piston rod is equipped with sealing ring.
Gasket is set between the needle-valve and piston.
Overflow hole is opened up on the piston, there are gaps between piston and piston rod and separation sleeve.
The air bag installation is there are two high-voltage tube, and one is air inlet pipe, and one is muffler, divides in air inlet pipe and muffler It An Zhuan not check valve.
In use, started by press bar, pushes needle-valve to open, hydraulic oil enters rod chamber, piston and piston rod by rodless cavity It is moved under pressure along cylinder barrel, inert gas is squeezed, and partially enters air bag by air inlet pipe;Unclamp starting bar, needle-valve Closure, gas spring locking;When pressure of the outer area load less than inert gas, starting bar is pressed, needle-valve is opened, and inert gas is by returning Tracheae enters cylinder barrel, piston rod and piston overhanging reset under the effect of the pressure.
The pressure of inert gas is adjusted the beneficial effects of the present invention are: the setting of external air bag is convenient, reduces gas Press the destruction to cylinder barrel;When air bag damage is convenient for changing;And cylinder barrel can be effectively prevent to explode, increase its safety;Suitably Increase the compression travel of piston.
Detailed description of the invention
