As preferably, described connecting rod is connected with back cylinder cover, and uses fastening nuts.

The utility model concept that breaks traditions, on the basis of Standard Gases, oil hydraulic cylinder, do not change in the situation of boundary dimension, adopt a plurality of circular piston bar structures, technique is simple, compact structure, good stability, cost is low, boundary dimension and standard gas-liquid, press identical, be conducive to coordinative composition of equipments producer type selecting supporting, have vast potential for future development.

Accompanying drawing explanation

Fig. 1 is a kind of structural representation of many capable of preventing piston rod from rotatings cylinder.

Embodiment

Below in conjunction with accompanying drawing and instantiation, the utility model is described in further details.

As shown in Figure 1, a kind of many capable of preventing piston rod from rotatings cylinder that the utility model is implemented, comprises cylinder barrel 1, front end housing 2, the first seal ring 3, piston rod 4, sliding bearing 5, the second seal ring 6, outer connecting base 7, the first screw 8, land 9, piston 10, the second screw 11, guidance tape 12, the 3rd seal ring 13, back cylinder cover 14, connecting rod 15, nut 16, P1 mouth 17, P2 mouth 18, ante-chamber 19, back cavity 20, described cylinder barrel 1 is in a side of anti-rotation cylinder, described front end housing 2 is connected with cylinder barrel 1, and seal with the first seal ring 3, described piston rod 4 is through front end housing 2, by sliding bearing 5, supported, the second seal ring 6 sealings, described outer connecting base 7 is connected with piston rod 4 use the first screws 8, described land 9 is connected with piston rod 4, described piston 10 is connected with land 9 use the second screws 11, and supported by guidance tape 12, the 3rd seal ring 13 sealings, described back cylinder cover 14 is connected with cylinder barrel 1, and seal with the first seal ring 3, described connecting rod 15 is connected with back cylinder cover 14, and fastening with nut 16, described P1 mouth 17 is connected with front end housing 2, described P2 mouth 18 is connected with back cylinder cover 14, described ante-chamber 19 is in the inside of cylinder barrel 1, described back cavity 20 is in the inside of back cylinder cover 14.

As preferably, described outer connecting base 7 is connected with piston rod 4 by the first screw 8.

As preferably, described piston 10 is connected with land 9 by the second screw 11, and is supported by guidance tape 12, and the 3rd seal ring 13 seals.

As preferably, described connecting rod 15 is connected with back cylinder cover 14, and fastening with nut 16.

Working principle of the present utility model: during use, fluid enters cylinder body back cavity through P2 mouth, promotes piston forward chamber and moves, and piston promotes piston rod and stretches out, and realizes power output, and ante-chamber fluid flows out from P1 mouth; After commutation, fluid enters cylinder body ante-chamber through P1 mouth, promotes piston and moves to back cavity, and piston driving piston rod is retracted, and back cavity fluid flows out from P2 mouth, completes a work cycle.Piston rod is in telescopic process, and owing to having adopted many piston rod constructions, piston rod position is limited by position, front end housing corresponding aperture hole, sliding bearing support guide, and the rotary freedom of piston, piston rod is completely restricted, and has therefore realized the object that prevents that piston rod from rotating.
