Abstract

The utility model discloses a piston sleeve for a hydraulic prop. The piston sleeve comprises a piston sleeve body (1), wherein the piston sleeve body (1) is provided with an annular connecting groove (2); a positioning groove (3) is arranged in the inner wall of one end of the piston sleeve body (1); and the width of the positioning groove (3) is a quarter of the perimeter of the inner wall of the piston sleeve body (1). The piston sleeve for the hydraulic prop disclosed by the utility model has the advantages of good stressing performance, strong impact resisting capability, firm and reliable connection and simple structure.

Description

A kind of piston bush that is used for hydraulic prop
Technical field
The utility model relates to a kind of piston bush that is used for hydraulic prop.
Background technology
The piston of hydraulic prop generally is equiped with the piston bush that is used for connector member, but the piston bush of prior art is generally realized the location between piston bush and the piston through retainingf key.Because the hydraulic prop of living bears bigger stress, and the retainingf key structure is less, often makes retainingf key damage easily, causes the syndeton of hydraulic prop to lose efficacy but in actual use.
Summary of the invention
The technical problem that the utility model will solve provides that good, the shock-resistant ability of a kind of stress performance is strong, firm and reliable connection, the piston bush that is used for hydraulic prop simple in structure.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is:
A kind of piston bush that is used for hydraulic prop; Comprise the piston bush body; Said piston bush body is provided with annular link slot, and the inwall of an end of said piston bush body is provided with locating slot, and the width of said locating slot is 1/4th of a said piston bush inner body wall girth.
Further improvement as technique scheme:
The bottom of said locating slot is parallel with the inwall of said piston bush body.
The both sides of said locating slot are level and smooth cambered surface.
The utlity model has following advantage:
The inwall of one end of the utility model piston bush body is provided with locating slot; And the width of locating slot is 1/4th of a piston bush inner body wall girth; Therefore the retainingf key of broad can be installed; Thereby can bear bigger stress and not fragile, have that good, the shock-resistant ability of stress performance is strong, a firm and reliable connection, advantage of simple structure.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art; To do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below; Obviously, the accompanying drawing in describing below only is some embodiment of the utility model, for those of ordinary skills; Under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the perspective view of the utility model embodiment.
Fig. 2 is the side-looking structural representation of the utility model embodiment.
Marginal data:
1, piston bush body;
2, annular link slot;
3, locating slot.
The specific embodiment
Below in conjunction with accompanying drawing the preferred embodiments of the present invention are set forth in detail, thereby protection scope of the present invention is made more explicit defining so that advantage of the present invention and characteristic can be easier to it will be appreciated by those skilled in the art that.
As depicted in figs. 1 and 2; The piston bush that present embodiment is used for hydraulic prop comprises piston bush body 1; Piston bush body 1 is provided with annular link slot 2, and the inwall of an end of piston bush body 1 is provided with locating slot 3, and the width of locating slot 3 is 1/4th of piston bush body 1 an inwall girth.
In the present embodiment, the bottom of locating slot 3 is parallel with the inwall of piston bush body 1.
In the present embodiment, the both sides of locating slot 3 are level and smooth cambered surface.
The above is merely the preferred implementation of the utility model, and the protection domain of the utility model is not limited in above-mentioned embodiment, and every technical scheme that belongs to the utility model principle all belongs to the protection domain of the utility model.For a person skilled in the art, some improvement and the retouching under the prerequisite of the principle that does not break away from the utility model, carried out, these improvement and retouching also should be regarded as the protection domain of the utility model.
