Abstract
The utility model discloses a kind of three pipe piston structures, it comprises setting two two pipes (2) within the outer tube, be connected and fixed by three pipes (3) between two described pipes (2), described two pipes (2) load end and inwardly offer annular groove (21), one end of described three pipes (3) are provided with manages (2) grafting with two and coordinates and the piston fixed (31), its the other end is provided with the pipe portion (32) of to manage (2) grafting with another root two and coordinating, the periphery place circumference of described piston (31) offers a ring recess (33), O type circle (34) and seal ring (35) is provided with in this groove (33), described seal ring (35) entirety is opening shape structure, flush with the periphery of piston (31) after its assembling.The utility model structure is simple, and easy to use, the seal ring after installation, can fill and lead up groove, and such piston does not just have the space of elastic dilatation, thoroughly stops the possibility that jam occurs.
Description
Technical field
The utility model relates to the manufacturing field of electric wheel relevant device, what be specifically related to is a kind of three pipe piston structures.
Background technique
The pipe piston of current mine truck has one wear ring, has certain elastic dilatation in its natural state, during installation, wear ring can flick and enter in two pipe clamp annular grooves, thus there is jam phenomenon, and once there is jam, piston just cannot be seated, also badly to disassemble.
Model utility content
The utility model object is to provide a kind of three pipe piston structures, and it can solve problem existing in background technique effectively.
In order to solve problem existing in background technique, it comprises setting two two pipes 2 within the outer tube, be connected and fixed by three pipes 3 between two described pipes 2, described two pipes 2 load end and inwardly offer annular groove 21, one end of described three pipes 3 is provided with and coordinates and the piston 31 fixed with two pipe 2 grafting, its the other end is provided with the pipe portion 32 coordinated with the grafting of another root two pipe 2, the periphery place circumference of described piston 31 offers a ring recess 33, O type circle 34 and seal ring 35 is provided with in this groove 33, described seal ring 35 entirety is opening shape structure, flush with the periphery of piston 31 after its assembling.
Owing to have employed above technological scheme, the utility model has following beneficial effect: structure is simple, and easy to use, the seal ring after installation, can fill and lead up groove, and such piston does not just have the space of elastic dilatation, thoroughly stops the possibility that jam occurs.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below.
Fig. 1 is structural representation of the present utility model.
Embodiment
The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with the accompanying drawing in the utility model embodiment, the technological scheme in the utility model embodiment being clearly and completely described.
Referring to Fig. 1, this embodiment is achieved by the following technical solutions, it comprises setting two two pipes 2 within the outer tube, be connected and fixed by three pipes 3 between two described pipes 2, described two pipes 2 load end and inwardly offer annular groove 21, one end of described three pipes 3 is provided with and coordinates and the piston 31 fixed with two pipe 2 grafting, its the other end is provided with the pipe portion 32 coordinated with the grafting of another root two pipe 2, the periphery place circumference of described piston 31 offers a ring recess 33, O type circle 34 and seal ring 35 is provided with in this groove 33, described seal ring 35 entirety is opening shape structure, flush with the periphery of piston 31 after its assembling.
Owing to have employed above technological scheme, the utility model has following beneficial effect: structure is simple, and easy to use, the seal ring after installation, can fill and lead up groove, and such piston does not just have the space of elastic dilatation, thoroughly stops the possibility that jam occurs.
Last it is noted that above embodiment is only in order to illustrate the technical solution of the utility model, be not intended to limit; Although be described in detail the utility model with reference to previous embodiment, those of ordinary skill in the art is to be understood that, it still can be modified to the technological scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature; And these amendments or replacement, do not make the essence of appropriate technical solution depart from the spirit and scope of each embodiment's technological scheme of the utility model.
