For the deficiency that prior art exists, the purpose of this utility model be to provide a kind of cushioning effect better, the not fragile and shock absorber for cylinder that working life is longer.
The technical solution of the utility model is achieved in that a kind of shock absorber for cylinder, it is characterized in that: comprise shock absorber body, this shock absorber body hollow is arranged, this hollow space forms piston rod receiving hole, the upper-end surface of described shock absorber body is upwards extended with ring-type positioning part, the upper edge of this positioning part constitutes holds mouth tightly, this diameter holding mouth tightly is less than the diameter of piston rod receiving hole, the lower end surface of described shock absorber body is extended with the first annular protrusion downwards, the cross section semicircular in shape of this first annular protrusion, the upper-end surface of described shock absorber body is provided with six positioning blocks, each positioning block is distributed on the upper-end surface of shock absorber body, the outer wall of described shock absorber body is provided with six groups of curve baths, each group of curve bath is distributed on the outer wall of shock absorber body, and each group curve bath comprises two arc grooves.
By adopting technique scheme, distinctive shock absorber is set, mouth to realize first step action of giving to the piston rod that backhaul is returned is held tightly by positioning part, then by the first annular protrusion, piston rod is realized to the action of giving of second step again, now, shock absorber body also plays auxiliary action of giving, thus achieve the effect of multi-buffer, six positioning blocks effectively raise the intensity of shock absorber body, and the curve bath on sidewall, improve the resilience after the outer wall distortion of this shock absorber, ensure that cushioning effect, not fragile, working life is longer.
The utility model is set to further: each group of described curve bath lays respectively between adjacent positioning block and arrange.
Be preferably, the upper-end surface of described shock absorber body comprises planar surface portion and inclined plane part, and positioning block is individually fixed on planar surface portion and inclined plane part.
By adopting technique scheme, while ensure that shock absorber bulk strength, the resilience effect after making shock absorber body also have compression, topology layout is more reasonable, resilience better effects if.
The utility model is set to further: the top of the inwall of described shock absorber body is provided with the second annular projection, the bottom of the inwall of shock absorber body is provided with the 3rd annular projection, this second annular projection and the 3rd annular projection form dashpot, and the 3rd annular projection is provided with four breach.
By adopting technique scheme, the inwall of shock absorber is provided with dashpot again, is that shock absorber body itself has certain cushioning effect, ensures that this shock absorber can realize multilayer buffering and play precondition, makes the topology layout of shock absorber more reasonable.
Accompanying drawing explanation
