Specific embodiment
The technical solution of the utility model is described further below in conjunction with accompanying drawing, but required protection domain is not It is confined to described;
As shown in Figures 1 to 3, a kind of reinforcement hydraulic cylinder that the utility model is provided, including cylinder body 1, pushing cylinder 3, push rod 4, work Plug A2 and piston B5, the bottom of the push rod 4 is fixed in bottom in cylinder body 1, and one end of the cylinder body 1 and pushing cylinder 3 is opening, pushes away Cylinder 3 is inserted in cylinder body 1, and in the insertion pushing cylinder 3 of push rod 4, the piston A2 and piston B5 is on push rod 4.
In the openend insertion cylinder body 1 of the pushing cylinder 3, the seal face of such pushing cylinder 3 just can be as the stress of hydraulic pressure Face, adds piston A2 lifting surface areas, and the reinforcement of twice causes more applicable.
The push rod 4 is hollow steel tube, is transported in pushing cylinder 3 high pressure liquid using hollow push rod 4, seals pushing cylinder 3 Pressure in end face is consistent with the pressure in the bottom of cylinder body 1, it is ensured that high pressure liquid is to the thrust on the seal face of pushing cylinder 3.
It is provided with the bottom side of the cylinder body 1, on the bottom side of push rod 4, on the side of cylinder body 1, on the side of pushing cylinder 3 logical Fluid apertures, liquid-through hole is used to pass in and out high pressure liquid, and liquid-through hole is used to connect extraneous high-voltage tube and the bottom of cylinder body 1 on the bottom side of cylinder body 1 Space;Liquid-through hole on the bottom side of push rod 4 is used to connect the bottom space of cylinder body 1 and the inner space of push rod 4;On the side of cylinder body 1 Liquid-through hole be used for the space connected in extraneous high-voltage tube and cylinder body 1;Liquid-through hole on the side of pushing cylinder 3 is used to connect in cylinder body 1 Space and pushing cylinder 3 in space.
The piston A2 is fixed in the openend side of pushing cylinder 3, and the piston B5 is fixed in the top side of push rod 4, that is, live Plug B5 is integrally fixed on push rod 4, and the space in pushing cylinder 3 is divided into two spaces by piston B5, and piston B5 is not moved, and is pushing cylinder 3 Medial surface is slided on piston B5 lateral surfaces;Piston A2 follows pushing cylinder to move, and the space in cylinder body 1 is divided into two spaces, Structure design compact and reasonable.
The openend of the cylinder body 1 is provided with centring ring 8, and pushing cylinder 3 is socketed in centring ring 8, centring ring 8, piston A2 and work Plug B5 is positioned to pushing cylinder 3 jointly, makes the motion stabilization reliability of pushing cylinder 3, and centring ring 8 also plays a part of sealed cylinder block 1.
The entire length of the pushing cylinder 3 is more than the length of cylinder body 1, to ensure to stablize pushing cylinder 3 with centring ring 8, it is ensured that this reality Use new reliability service.Piston A2 filled sections are the lateral surface of push rod 4 to the medial surface of cylinder body 1, and piston A2 is in the outside of push rod 4 Slided between the medial surface of face and cylinder body 1, it is ensured that the hydraulic oil at piston A2 two ends will not be revealed;Piston B5 filled sections are push rod 4 Lateral surface to pushing cylinder 3 medial surface, piston B5 slides between the lateral surface of push rod 4 and the medial surface of pushing cylinder 3, it is ensured that piston The hydraulic oil at B5 two ends will not be revealed.
The utility model each several part packaging technology:
