The bottom of the inserted block is provided with jack, and the support column is inserted in the inside of jack, is all provided with left and right sides of the inner side of the outer shroud
There is annular projection piece, the top of the outer shroud is provided with groove.
Preferably, the bottom even of the inner ring, which runs through, through hole, and the quantity of through hole is no less than three.
Preferably, the groove is evenly distributed on the outside of outer shroud, and the quantity of groove is no less than five.
Preferably, the quantity of the inserted block is no less than four, and inserted block is evenly distributed on the inner side of neck.
Preferably, the quantity of the annular projection piece is no less than four, and annular projection piece is to be placed equidistant.
Preferably, it is equipped with lug at left and right sides of the outer shroud.
Compared with prior art, the beneficial effects of the utility model are：The guide ring is made by the setting of inner ring and outer rings
Obtaining the guide ring can protect the projection of piston not frayed, improve the service life of piston, be inserted in by support column
Setting inside jack so that when the extruding that outer shroud is subject to is bigger, the connection of inner ring and outer shroud is closer.

Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belong to the scope of the utility model protection.
Fig. 1-3 are referred to, the utility model provides a kind of technical scheme：A kind of piston type oil cylinder guiding ring, including inner ring 1
With outer shroud 2, the top left and right sides of the inner ring 1 is equipped with locating slot 3, and the inside bottom of the locating slot 3 is provided with support column
4, the inner ring 1 is inserted in inside the neck 8 that the inner side of outer shroud 2 opens up, and the inner side of the neck 8, which is provided with, to be inserted in locating slot 3
The inserted block 5 of chamber, the bottom of the inserted block 5 are provided with jack 6, and the support column 4 is inserted in the inside of jack 6, the outer shroud 2 it is interior
Annular projection piece 9 is equipped with left and right sides of side, the top of the outer shroud 2 is provided with groove 10.
Further：The bottom even of the inner ring 1, which runs through, through hole 7, and the quantity of through hole 7 is no less than three so that
Inner ring 1 has toughness when inserting the groove on the outside of piston, the deformation of inner ring 1 is reduced, so as to improve the sealing of guide ring.
Further：The groove 10 is evenly distributed on the outside of outer shroud 2, and the quantity of groove 10 is no less than five, uses
In oil in storage, so that the better tightness of outer shroud 2 and cylinder block inwall.
Further：The quantity of the inserted block 5 is no less than four, and inserted block 5 is evenly distributed on the inner side of neck 8 so that
Outer shroud 2 and the fixed effect of inner ring 1 are more preferable.
Further：The quantity of the annular projection piece 9 is no less than four, and annular projection piece 9 is used for be placed equidistant
