Abstract

The utility model discloses a multipurpose oil cylinder, which is used for solving the problems that existing oil cylinders are complex in structure and high in manufacturing cost, functions of the existing oil cylinders are limited as hydraulic oil only circulating in the oil cylinders enables the cylinders to telescope only, and the like. A cylinder block (3) of the multipurpose oil cylinder is provided with two oil inlets (1) on the lateral wall of the bottom, and the upper portion of a piston rod (4) is provided with an oil outlet (6) of a central oil pipe (5) outside the cylinder block (3). Therefore, the multipurpose oil cylinder is simple in structure, and capable of telescoping and delivering hydraulic oil out of the oil cylinder.

Description

The multipurpose oil cylinder
Technical field
The utility model relates to a kind of oil cylinder, relates in particular to a kind of multipurpose oil cylinder of being made up of cylinder body, piston, piston rod, filler opening, oil outlet and center transport pipe.
Background technique
Chinese patent CN86101725A discloses the double-stage double-acting telescopic oil cylinder of a kind of like this center oil transportation; Its structural feature is: by Master cylinder body; The first order piston that can in Master cylinder body, slide, the second level piston that has hollow piston rod that can in first order piston, slide and center transport pipe are formed, and the cylindrical oil pocket that the oilhole that is positioned at the oil cylinder bottom passes cylinder base and Master cylinder body communicates; The axial guide hole that is positioned at first order piston base is linked up this cylindrical oil pocket and the 4th annular chamber that is positioned at below the piston base of the second level; Radially guide hole in the first order piston base is positioned at the upside of this piston base, and the one of which end communicates with the interior guide hole of center transport pipe that is fixed on this grade piston base, and the other end is linked up first order piston base upside outer wall and the formed annular chamber of Master cylinder body inwall; Second level piston base upside also has radially guide hole; This hole make the annular chamber that forms between second level piston base upside outer wall and first order piston inner wall and be positioned at second level piston upper inside wall and center transport pipe outer wall between the 3rd annular chamber link up, and communicate naturally on second annular chamber that forms between first annular chamber that forms between first order piston external wall of upper portion and Master cylinder body inwall and annular chamber and second level piston external wall of upper portion and first order piston inner wall and the ring cavity structure, therefore; This oil cylinder collapsing length is longer; Be applicable to the occasion that can not maybe should not use oil hose, but, because this structure is comparatively complicated; Manufacture cost is higher; Because hydraulic oil only circulates, only work making the oil cylinder telescopic action again in oil cylinder, function is limited.
Summary of the invention
The purpose of the utility model provides a kind of simple in structure, oil cylinder is stretched can hydraulic oil be delivered to the multipurpose oil cylinder mechanically beyond the oil cylinder again.
For achieving the above object, the utility model multipurpose oil cylinder is made up of cylinder body, piston, piston rod, filler opening, oil outlet and center transport pipe; Be provided with filler opening in cylinder base; Be provided with oil outlet on cylinder body top, the center transport pipe is arranged on the piston rod central position, and its axis overlaps with the piston rod axis; The sidewall of cylinder base is provided with two filler openings, and cylinder body is outside equipped with the oil outlet of center transport pipe on piston rod top.
Two filler openings are on the sidewall of cylinder base and are symmetrical set.
After adopting this structure, because the sidewall of cylinder base is provided with two filler openings, cylinder body is outside equipped with the oil outlet of center transport pipe on piston rod top.Thereby reach simple in structure, oil cylinder is stretched can hydraulic oil be delivered to the purpose mechanically beyond the oil cylinder again.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is done further to specify.
Accompanying drawing is that the master of the utility model multipurpose oil cylinder looks schematic representation.
Among the figure: 1. filler opening 2. pistons 3. cylinder bodies 4. piston rods 5. center transport pipe 6. oil outlets.
Embodiment
The multipurpose of the utility model shown in accompanying drawing oil cylinder; Form by cylinder body 3, piston 2, piston rod 4, filler opening 1, oil outlet 6 and center transport pipe 5, be provided with filler opening 1, be provided with oil outlet 6 on cylinder body 3 tops in cylinder body 3 bottoms; Center transport pipe 5 is arranged on piston rod 4 central positions; Its axis and piston rod 4 deads in line, the sidewall of cylinder body 3 bottoms is provided with two filler openings 1, is outside equipped with the oil outlet 6 of center transport pipe 5 at piston rod 4 top cylinder bodies 3; Two filler openings 1 are on the sidewall of cylinder body 3 bottoms and are symmetrical set.

Claims (2)

1. multipurpose oil cylinder; Form by cylinder body, piston, piston rod, filler opening, oil outlet and center transport pipe, be provided with filler opening, be provided with oil outlet on cylinder body top in cylinder base; The center transport pipe is arranged on the piston rod central position; Its axis overlaps with the piston rod axis, it is characterized in that: the sidewall of cylinder body (3) bottom is provided with two filler openings (1), is outside equipped with the oil outlet (6) of center transport pipe (5) at piston rod (4) top cylinder body (3).
2. multipurpose oil cylinder according to claim 1 is characterized in that: two filler openings (1) are on the sidewall of cylinder body (3) bottom and are symmetrical set.
