Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model.
Specific embodiment
Hydro-pneumatic buffer is made of cylinder 1 and oil cylinder 2, and the piston rod 4 in oil cylinder 2 is hollow structure；Inside piston rod 4
Equipped with slider 5, slider 5 can the reciprocal priming in piston rod 4, formed between 4 extension end of slider 5 and piston rod airtight
Structure is cylinder 1；Piston rod 4 is located between one end in oil cylinder 2 and oil cylinder 2 through damping hole connection, forms decompression oil cylinder knot
Structure；Piston rod 4 is driven by throttling mandrel 3 and is moved back and forth.When instantaneous impact force is applied to buffer head 6, compression piston bar 4
It is moved to 2 direction of oil cylinder, the oil in oil cylinder 2 is under pressure extruding at this time, by damping hole to the decompression oil cylinder of piston rod inner
Movement squeezes slider 5, makes the gas in 5 compression cylinder 1 of slider and move to cylinder direction, played by gas secondary
The effect of buffering.After slider 5 moves to the extreme position of gas pressure, pressure that cylinder interior gas applies slider
Greater than the pressure that the oil in decompression oil cylinder applies to slider, slider is mobile towards oil cylinder direction again, thus resets.
The extension end of piston rod 4 is equipped with buffer head 6, and piston rod 4 stretches out oil cylinder portion of external and is cased with protective jacket 7, prevents
Sheath 7 is dustproof construction, and dust is prevented to be attached on piston rod；Outside oil cylinder 2 be equipped with mounting base 8, using be can be in mounting base 8
Upper installation label is isostructural simultaneously, will not influence the integraty and airtightness of buffer.
The integral structure for the stacking that the slider 5 is two layers, every multilayer laminated structure are equipped with a slider sealing
Circle 9.The slider of two layers of integral structure can increase the leakproofness of cylinder, extend the service life of buffer.It is described every
In vitro sealing ring 9 is for hole with square grid come sealing ring.
One end that the piston rod 4 is equipped with buffer head 6 is equipped with end plug 10, and the side of end plug 10 is equipped with for sealing
U-shaped sealing ring 11,12 be attached between end plug 10 and buffer head 6 by nail.
2 end of oil cylinder is equipped with support sleeve 13, the outer end of support sleeve 13 by screw with 4 contact portion of piston rod
Equipped with J-type dirt-proof boot 14.
