Description
Technical field
This utility model relates to cylinder technical field, particularly relates to anti-rotation pneumohydraulic pressure-cylinder in a kind of piston.
Background technology
Pneumohydraulic pressure-cylinder is all circular due to cylinder barrel, so all adopt external anti-rotation structure when needs prevent piston rotation, thus causing structure loaded down with trivial details, volume increases.
Utility model content
The purpose of this utility model is in that to provide anti-rotation pneumohydraulic pressure-cylinder in a kind of piston for the deficiencies in the prior art, anti-rotation pneumohydraulic pressure-cylinder modern design, simple in construction in this piston, and anti-rotation is effective, assembling simplicity.
For reaching above-mentioned purpose, this utility model is achieved through the following technical solutions.
Anti-rotation pneumohydraulic pressure-cylinder in a kind of piston, include cylinder body, it is screwed on drive end bearing bracket and the rear end cap at cylinder body two ends, it is located at the piston in cylinder body and piston rod, described piston upper end is provided with at least one and piston rod through hole in the same direction, being arranged with guide post in through hole, one end of guide post is installed in the drive end bearing bracket fixing hole that described drive end bearing bracket is provided with, and the other end of guide post is installed in the rear end cap fixing hole that described rear end cap is provided with.
Wherein, described piston rod is arranged with the sealing ring being fixed on described drive end bearing bracket.
Wherein, described piston rod and described guide post are equiped with in described cylinder body and are parallel to each other.
Wherein, the axis that the quantity of described through hole, guide post, drive end bearing bracket fixing hole and rear end cap fixing hole is identical and corresponding is identical.
The beneficial effects of the utility model are: anti-rotation pneumohydraulic pressure-cylinder in a kind of piston described in the utility model, include cylinder body, it is screwed on drive end bearing bracket and the rear end cap at cylinder body two ends, it is located at the piston in cylinder body and piston rod, described piston upper end is provided with at least one and piston rod through hole in the same direction, being arranged with guide post in through hole, one end of guide post is installed in the drive end bearing bracket fixing hole that described drive end bearing bracket is provided with, and the other end of guide post is installed in the rear end cap fixing hole that described rear end cap is provided with.This utility model has modern design, simple in construction, and anti-rotation is effective, the advantage that assembling is easy.

Detailed description of the invention
Below in conjunction with specific embodiment, this utility model is illustrated.
As shown in Figure 1-2, anti-rotation pneumohydraulic pressure-cylinder in a kind of piston, include cylinder body 1, it is screwed on drive end bearing bracket 2 and the rear end cap 3 at cylinder body 1 two ends, being located at the piston 4 in cylinder body 1 and piston rod 5, described piston 4 upper end is provided with at least one and piston rod 5 through hole 41 in the same direction, is arranged with guide post 42 in through hole 41, one end of guide post 42 is installed in the drive end bearing bracket fixing hole 21 that described drive end bearing bracket 2 is provided with, and the other end of guide post 42 is installed in the rear end cap fixing hole 31 that described rear end cap 3 is provided with.
Further, described piston rod 5 is arranged with the sealing ring 51 being fixed on described drive end bearing bracket 2.
Further, described piston rod 5 and described guide post 42 are equiped with in described cylinder body 1 and are parallel to each other.
Further, the axis that the quantity of described through hole 41, guide post 42, drive end bearing bracket fixing hole 21 and rear end cap fixing hole 31 is identical and corresponding is identical, and the preferred quantity of the present embodiment is one.
Need to further explain, this utility model adopts the internal piston 4 of cylinder body 1 to install the guide post 42 of sealing additional, only need as control mode can reach pneumohydraulic pressure-cylinder action and prevent the rotation of piston 4, do not change existing pneumohydraulic pressure-cylinder overall dimensions, the expense of later stage mounting structure can be reduced.
Above content is only preferred embodiment of the present utility model, for those of ordinary skill in the art, according to thought of the present utility model, all will change in specific embodiments and applications, this specification content should not be construed as restriction of the present utility model.
