Abstract
The invention discloses a cylinder sleeve of an oil cylinder. The cylinder sleeve comprises a pedestal, wherein the pedestal is of a shape like a Chinese character tu and is provided with a hollow interior, and the upper part of the pedestal is connected with a first sleeve body; the outer peripheries of the upper part and the lower part of the first sleeve body are both provided with multiple circles of first sealing ring grooves which are arranged up and down, and the outer periphery of the middle of the first sleeve body is uniformly provided with a plurality of inclined holes; the upper part of the first sleeve body is connected with a second sleeve body, and the outer periphery of the second sleeve body is provided with at least one second sealing ring groove; and the first sleeve body and the second sleeve body are both provided with a hollow interior. The cylinder sleeve provided by the invention has the advantages of sealability, operational reliability, convenience in maintenance, and saves cost.
Description
Technical field:
The present invention 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 are the plane or on top interior, are provided with small boss, when being connected with cylinder cap, be equipped with pad each other; Fix through assembling bolt, with the assurance sealing, but when oil cylinder is worked; Because the pressure effect, the pad between cylinder sleeve and cylinder cap can be by pressure effect displacement, after damage; Water in the body will get into oil cylinder, cause the quality of the inner oil of oil cylinder to be 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 objective of the invention is provides a kind of sealing, reliable operation in order to overcome above deficiency, easy to maintenance, practices thrift the cylinder sleeve of the oil cylinder of cost.
The object of the invention is realized through following technological scheme: a kind of cylinder sleeve of oil cylinder; Comprise base, base is " protruding " font, and is the boring structure; Be externally connected to first body in the base upper end; Be equipped with many circles on the first body upper and lower excircle and go up first o-ring groove of held, 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; On the second body top excircle, be provided with at least one second o-ring groove, first body and second body are the boring structure.
Further improvement of the present invention is: be equipped with three circles, first o-ring groove on the said first body upper and lower excircle.
The present invention 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, practiced thrift 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.
Description of drawings:
Fig. 1 is a structural representation of the present invention;
Label among the figure: 1-base, 2-first body, 3-first o-ring groove, 4-second body, 5-second o-ring groove, 6-inclined hole.
Embodiment:
In order to deepen to understanding of the present invention, will combine embodiment and accompanying drawing that the present invention is made further detailed description below, this embodiment only is used to explain the present invention, does not constitute the qualification to protection domain of the present invention.
Show the embodiment of the cylinder sleeve of a kind of oil cylinder of the present invention like Fig. 1, comprise base 1, base 1 is " protruding " font; And be the boring structure, base 1 upper end is externally connected to and is equipped with first o-ring groove 3 that many circles are gone up held on first body, 2, the first bodies, the 2 upper and lower excircles; On first body, 2 middle part excircles, evenly be provided with a plurality of inclined holes 6; First body, 2 upper ends are internally connected with second body 4, on second body, 4 top excircles, are provided with at least one second o-ring groove, 5, the first body 2 and second body 4 and are the boring structure; The present invention preferably is equipped with three circles, first o-ring groove 3 on first body, 2 upper and lower excircles; Cylinder sleeve is synthetic by a plurality of parts assembly units, and it is comparatively convenient after damage, to keep in repair, and does not need integral replacing; Practiced thrift cost; In first o-ring groove 3 and second o-ring groove 5, seal ring is set, has guaranteed the sealing when cylinder sleeve is connected with miscellaneous part, thereby further guaranteed the quality of the oil of cylinder interior.
