Description
Technical field:
The utility model relates to the cylinder sleeve of a kind of cylinder sleeve, particularly a kind of oil cylinder.
Background technique:
Existing oil cylinder cylinder sleeve, its top is the plane or is provided with small boss on top interior, when being connected with cylinder cap, be equipped with pad each other, fix by assembling bolt, with the assurance sealing, but when oil cylinder is worked, because the pressure effect, pad between cylinder sleeve and cylinder cap can be shifted by the pressure effect, after damage, the water in the body will enter oil cylinder, causes the quality of oil of oil cylinder inside destroyed, and existing cylinder sleeve is an integrated type, easy-maintaining not after damage must be changed again, makes cost improve.
Summary of the invention:
The purpose of this utility model is in order to overcome above deficiency, a kind of sealing, reliable operation to be provided, and is easy to maintenance, saves the cylinder sleeve of the oil cylinder of cost.
The purpose of this utility model is achieved through the following technical solutions: a kind of cylinder sleeve of oil cylinder, comprise base, base is " protruding " font, and be the boring structure, be externally connected to first body in the base upper end, be equipped with first o-ring groove that multi-turn is placed up and down on the first body upper and lower excircle, on the excircle of first body middle part, evenly be provided with a plurality of inclined holes, first body upper end is internally connected with second body, be provided with at least one second o-ring groove on the second body top excircle, first body and second body are the boring structure.
Further improvement of the utility model is: be equipped with three circles, first o-ring groove on the described first body upper and lower excircle.
The utility model compared with prior art has the following advantages: cylinder sleeve is synthetic by a plurality of parts assembly units, maintenance is comparatively convenient after damage, and do not need integral replacing, saved cost, in first o-ring groove and second o-ring groove, seal ring is set, guarantee the sealing when cylinder sleeve is connected with miscellaneous part, thereby further guaranteed the quality of the oil of cylinder interior.
