Description

What a kind of band controlled switch can the gas spring of bi-directional drive
Technical field
The present invention relates to a kind of band control switch can the gas spring of bi-directional drive, the most described gas bullet Spring described control switch the two states opened or closed switching under, the piston rod of described gas spring can beyond Go out elongation or retraction shortens；It is a kind of cleaning, environmental protection, energy-conservation mechanical engineering aerodynamic force parts；Enter One step, the piston two ends of described gas spring or piston component two ends are respectively arranged with a working beam and and control bar, Described working beam and described control bar are piston rod, and described control bar is to have rigid material empty in, institute Stating working beam external diameter and be less than described control bar external diameter, described gas spring provides one and passes through on or off High pressure gas environment in described control bar and outside described control bar, it is achieved drive working beam or control bar motion The control method that direction changes.
Background technology
Gas spring be one can rise support, buffer, brake, the merit such as height adjustment and angular adjustment Energy property accessory, is widely used in the fields such as armarium, automobile, furniture, Weaving device, machine-building. Principle is to be filled with noble gas or oil gas mixture in airtight cylinder barrel, makes cylinder cylinder pressure higher than air Several times of pressure or tens times, the cross-sectional area of piston rod is utilized less than piston cross-section area thus to produce pressure Power difference realizes the motion of piston rod.
At present, during gas spring work, it is all unidirectional drive；During the work of described gas spring, close Gases at high pressure, described gases at high pressure are had to act on gas spring piston two ends lifting surface area in the cylinder barrel closed Producing pressure differential, the piston lifting surface area having piston rod one end is less, when two ends gases at high pressure pressure is equal, The bigger pressure acting on the end face not having piston rod one end is had to promote piston to have piston rod one extreme direction to piston Moving, piston rod goes out to extend, and when the effect not having external force, this motion is unidirectional.
At present, it is all unidirectional drive due to gas spring, after piston rod goes out elongation, is can not Directly utilize the gases at high pressure in airtight cylinder barrel, allow piston opposite direction move, piston rod i.e. can not be allowed to bounce back Shorten；Further, to allow piston rod retraction shorten, it is necessary to apply a concentric on the piston rod and refer to Shorten the external force in direction to piston rod retraction, when described external force and described airtight cylinder barrel inner high voltage gas effect Power on the piston having piston rod one end and more than or equal to drive piston rod go out elongation power time, institute The piston rod stating gas spring makees retraction direction motion, and piston rod retraction shortens, it is achieved piston opposite direction is moved.
Summary of the invention
It is an object of the invention to: provide a kind of band control switch can the gas spring of bi-directional drive, i.e. Described gas spring described control switch the two states opened or closed switching under, the work of described gas spring Stopper rod can go out to extend or bounce back to shorten；The described control switch of described gas spring can be mechanical, Can also be electric；Further, described control switch can be directly actuated, it is also possible to is indirect Control；Further, the described switch that controls can be local control, it is also possible to remotely control；Enter One step ground, described gas spring has in gases at high pressure device in further relating to a kind of airtight cylinder barrel, described gas The piston two ends of spring or piston component two ends are respectively arranged with a working beam and and control bar, described working beam and described Controlling bar and be piston rod, described control bar is to have rigid material empty in, and described working beam external diameter is less than Described control bar external diameter, described inner cavity of cylinder cross-sectional area deducts described second piston rod cross-sectional area more than institute Stating inner cavity of cylinder cross-sectional area and deduct first piston bar cross-sectional area, described gas spring provides one to be passed through Control in bar the high pressure gas environment outside with described control bar described on or off, it is achieved drive working beam or Control the control method that the bar direction of motion changes.
