Abstract

The utility model belongs to the technical field of the jack, especially, relate to a pressfitting machine hydraulic jack's cylinder body, grooved underside upwards sets up the jump ring perpendicularly, the jump ring is upwards connected and is filled in in angelica grosseserrata, the retaining ring vertical activity that the angelica grosseserrata stopper cup jointed through its top connects the valve piston in locking in the retaining ring, the utility model provides a prior art have structure complicacy, impracticable problem, have the structure of the hydro -cylinder of the cylinder body of having protected the jack, simplification, the assembly of being convenient for, useful technological effect that the leakproofness is good.

Description

A kind of cylinder body of pressing machine hydraulic jack
Technical field
The utility model belongs to technical field of jacks, more particularly to a kind of cylinder body of pressing machine hydraulic jack.
Background technology
Pressure jack, also known as hydraulic jack, is a kind of jack of employing plunger or hydraulic cylinder as rigid top lift part, Simple crane gear typically only has lifting mechanism, to raising weight, simple structure, it is lightweight, be easy to carry, movement side Just, conventional simple crane gear has hydraulic jack, coaster and hoist engine etc., and prior art has complex structure, impracticable Problem.
The content of the invention
The utility model provides a kind of cylinder body of pressing machine hydraulic jack, to solve above-mentioned background technology in propose it is existing There is complex structure, unpractical in technology.
The technical problem that the utility model is solved employs the following technical solutions to realize:A kind of pressing machine hydraulic jack Cylinder body, including the cylinder body of centrally disposed circular groove, the groove floor is vertically arranged upwards jump ring, and the jump ring connects upwards It is connected to big piston, the locating snap ring Vertical movements of the big piston Jing its top end socket are connected to the little work for being stopped at locating snap ring Plug.
Further, the cylinder body is ellipsoid.
Further, the big piston bottom end filling working oil being arranged in groove.
Further, the groove floor is vertically arranged upwards jump ring including the groove floor Jing O-ring and sealing ring On be vertically arranged jump ring.
Further, the jump ring connect up in big piston include the jump ring Jing O-rings and sealing ring connect up in Big piston.
The beneficial effects of the utility model are:
1st, this patent is vertically arranged upwards jump ring using the groove floor, and the jump ring is connected up in big piston, institute The locating snap ring Vertical movements for stating big piston Jing its top end sockets are connected to the valve piston for being stopped at locating snap ring, when in use, Because locating snap ring limits the scope of activities of valve piston, therefore, it is effectively protected the cylinder body of jack.
2nd, this patent fills working oil using the big piston bottom end being arranged in groove, because working oil is passed in cylinder body It is dynamic, and without large tank and small oil tank structure, the structure of simplified oil cylinder.
3rd, this patent arranges brake using the pneumatic motor main shaft, spacing by rotating shaft Jing blocks in pneumatic motor, Swing in the range of 90 °, due to need not the whole swing circles of Jing just complete to cut, therefore reduce work(speed of cut is improve Consumption.
4th, this patent is lightweight, easy to carry, is easy to assembling.
5th, this patent has good sealing.
Description of the drawings
Fig. 1 is a kind of housing structure schematic diagram of pressing machine hydraulic jack of the utility model.
Specific embodiment
The utility model is described further below in conjunction with accompanying drawing:
In figure:1- grooves, 2- cylinder bodies, 3- jump rings, the big pistons of 4-, 5- locating snap rings, 6- valve pistons, 7-O shape circles, 8- sealings Ring.
Embodiment:
The present embodiment:As shown in figure 1, a kind of cylinder body of pressing machine hydraulic jack, including centrally disposed circular groove 1 Cylinder body 2, the bottom surface of the groove 1 is vertically arranged upwards jump ring 3, and the jump ring 3 is connected up in big piston 4, the Jing of big piston 4 The Vertical movements of locating snap ring 5 of its top end socket are connected to the valve piston 6 for being stopped at locating snap ring 5.
The cylinder body 2 is ellipsoid.
The bottom of the big piston 4 filling working oil being arranged in groove 1.
The bottom surface of the groove 1 is vertically arranged upwards jump ring 3 including the bottom surface Jing O-ring 7 of the groove 1 and sealing ring 8 upwards It is vertically arranged jump ring 3.
The jump ring 3 is connected up includes that the Jing O-rings 7 of the jump ring 3 and sealing ring 8 are connected up in big in big piston 4 Piston 4.
Operation principle:
This patent is vertically arranged upwards jump ring by the groove floor, and the jump ring is connected up in big piston, described The locating snap ring Vertical movements of big its top end socket of piston Jing are connected to the valve piston for being stopped at locating snap ring, when in use, by The scope of activities of valve piston is limited in locating snap ring, the utility model solves prior art to have complex structure, unpractical ask Topic, with protect the cylinder body of jack, the structure of the oil cylinder of simplification, be easy to assemble, the Advantageous Effects of good airproof performance.
Using the technical solution of the utility model, or those skilled in the art is in the inspiration of technical solutions of the utility model Under, similar technical scheme is designed, and above-mentioned technique effect is reached, fall into protection domain of the present utility model.
