Description
Technical field
The utility model relates to a kind of Novel shock absorbing device.
Background technique
The demand of shock absorber is because spring can not settle out at once, and after that is spring is compressed and decontrols, it can continue for some time stretches not only but also contract, so shock absorber can absorb wheel run into vibrations caused by concave-convex road surface, makes ride comfort.But due to spring through compress frequently with open after can produce fatigue, its elastic force can reduce gradually, until spring failure, and will to change spring be unusual red tape.The now appearance of existing air pressure shock absorber, clearly, it does not have the problem of spring failure to the advantage of this shock absorber, as long as ensure sealing, shock absorber just can very stably work.Visible, the sealing of air pressure shock absorber often determines the quality of its performance.But existing shock absorber or poor sealing, shock-proof effect instability, or it is expensive to fake because precision makes.
Model utility content
Therefore, for above-mentioned problem, the utility model proposes a kind of structure simple, can adjust that height, cost are lower, the Novel shock absorbing device of good damping effect, good seal performance as required.
For achieving the above object, the utility model have employed following technological scheme: a kind of Novel shock absorbing device, comprise cylindrical shell, piston rod, the two ends of described cylindrical shell are respectively equipped with upper end cap and lower end cap, described piston rod extends in cylindrical shell through upper end cap, one end that described piston rod is positioned at cylindrical shell be provided with can with the piston of cylinder inboard wall close contact, cylindrical shell is separated into upper cavity and lower chamber by described piston, described piston rod is hollow stem, its one end is communicated with lower chamber, the other end is provided with air inlet nozzle, described cylindrical shell is provided with the regulating the qi flowing in the channels mouth be communicated with upper cavity, the periphery of described cylindrical shell is threaded a urceolus that can connect locomotive.
Further, described upper end cap is positioned at the guide sleeve be provided with piston rod joint for limited piston bar, described upper end cap and piston rod joint and the top being positioned at guide sleeve is provided with oil sealing.
Further, the upper end of described piston rod is provided with a fixed block be connected with locomotive, and the periphery of described piston rod is provided with yielding rubber between fixed block and cylindrical shell.
Further, described piston be circumferentially provided with a piston ring for sealing, the both sides up and down being circumferentially positioned at piston ring of described piston are respectively equipped with seal ring.
Further, the side near upper end cap on described piston is provided with the cushion pad preventing piston and upper end cap from colliding.
Further, described upper and lower end covers and is respectively equipped with O type circle with the joint of cylindrical shell.
By adopting preceding solution, the beneficial effects of the utility model are: compared with existing shock absorber, cylindrical shell is separated into upper and lower cavity by the piston being located at piston rod by this Novel shock absorbing device, the mode of pressurized gas is utilized to realize shock-absorbing function, and the periphery of cylindrical shell is threaded and is provided with urceolus, the size of cushioning ability is realized by the adjustment of urceolus, also the size of cushioning ability is realized by adjustable pressure, the mode that damping is regulated is more various, have more practicability, and damping effect is also better; Further, by arranging guide sleeve and oil sealing, make the relative movement of piston rod and cylindrical shell more steady, and sealing is also better; Further, by arranging yielding rubber, cause the collision of fixed block and cylindrical shell when a surface vibration is huge, noise is less, more not fragile; Further, seal ring is set by the both sides up and down at piston ring, makes sealing effect better; Further, by arranging cushion pad, to avoid the hard contact of piston and upper end cap, and cause damage.
