Description
Technical field
The present invention relates to buffer unit field, particularly relate to fender pile structure.
Background technology
Fender pile is between a kind of object of being located at two relative motions, for cushioning its speed of related movementDevice, to reach the collision power reducing between object or the effect that reduces noise, being specifically often applied to can be certainlyOn the moving door body or drawer sliding rail returning, refer to the partial enlarged drawing that Figure 1 shows that existing fender pile,It mainly lies in the interior axostylus axostyle 12 that is axially equipped with of an outer tube 11, and the company connecting in these axostylus axostyle 12 one endFitting 13 is provided with a piston ring 14, and this piston ring 14 is provided with a loop portions 141 and a skirt section 142, by this,In order to do in the time that this axostylus axostyle 12 is shifted towards close these piston ring 14 directions, loop portions 141 and the skirt of this piston ring 14Portion 142 can be strutted equably by the ejection of this connector 13, and makes this loop portions 141 and skirt section 142Form good airtight conditions and friction with outer tube 11 inwalls, and then this fender pile can be reached provide buffering effectObject.
The fender pile that this is commonly used, though can reach the object that buffering effect is provided, this axostylus axostyle 12 is towards living near thisWhen plug ring 14 direction displacement, also can make the air of outer tube 11 inside compressed simultaneously, thereby when this axostylus axostyle 12While promoting piston ring 14 near outer tube 11 bottom, the thrust that axostylus axostyle 12 often occurs is less than outer tube 11 insideThe situation of air pressure, causes axostylus axostyle 12 successfully to advance, by the time the ring of this piston ring 14Portion 141 restore to the original state with skirt section 142 and while making air pressure in outer tube 11 be less than the thrust of axostylus axostyle 12Can continue to advance, cause fender pile action to have some setbacks, and then it is tired to cause production reliability to reduce with userDisturb.
Summary of the invention
The present invention will solve existing fender pile, and in cushion stroke, the air pressure in outer tube is difficult for rowGo out, cause axostylus axostyle action to have some setbacks, cause awkward problem, and a kind of fender pile structure is provided.
A fender pile structure, it comprises: an outer tube, this outer tube one end is open shape, this outer tube other endBe provided with a pressure relief mechanism; One push rod, this push rod system is arranged in this outer tube slippingly, and these push rod two ends are dividedBe not provided with one and be driven portion and a piston connecting portion, this push rod is provided with a support member, this piston connecting portion withBetween support member, be provided with one first locating part, this piston connecting portion end is provided with one second locating part; One piston piece,This piston piece is arranged in its piston connecting portion periphery of push rod; One piston fastener, this piston fastener is arranged inIts piston connecting portion periphery of push rod, and this piston fastener is sheathed on this piston piece inside.
By said structure, the present invention can be according to the moving direction of push rod, realizes the exhaust of inequality and entersGas control system, thereby not only can guarantee buffering effect, smoothness also can keep push rod to draw outward time simultaneously, and thenMake the present invention can reach simplified structure and the effect that improves production reliability.
