Abstract
Existing commercially available hydraulic jack can only be placed straight up and could use, and the object of the invention is exactly to be a kind of flexible cylinder type hydraulic jack of head it off design-calculated.Its adopts flexible material to make tool for oil cylinder, utilizes atmospheric pressure, make oil storage liquid cylinder be in outward any heeling condition not can with oil-sucking hole on the base from sky, thereby guarantee that jack can universal use.
Description
Existing commercially available hydraulic jack can only be placed straight up and could use, and this has limited the range of use of hydraulic jack undoubtedly.
The present invention looks for purpose and just provide a kind of flexible oil storage cylinder universal hydraulic jack that can both normally use of placing under any heeling condition.
Fig. 1 shows structure cutaway view of the present invention.Wherein, the 1st, base, the 2nd, annular pressure pad, the 3rd, load oil cylinder, the 4th, the glue bowl, the 5th, retracing spring, the 6th, flexible oil storage cylinder, it is to adopt the oil resisting material of rubber or other quality softness to make, the 7th, the banding circle, the 8th, plunger, the 9th, wind, the 10th, manual plunger, the 11st, small oil tank, 12 and 15 all is boiler check valve, its valve is to adopt spring constraint, thereby no matter be in any heeling condition, boiler check valve can both normal operation, the 13rd, the oil suction road, the 14th, high-pressure oil passage, the 16th, oil return line, the 17th, cone valve, load oil cylinder 3 and manual oil cylinder 11 are fixed on the base 1, the bottom of flexible oil cylinder 6 is screwed on base by pressure pad 2, upper end then lock ring forms a flexible oil storage cylinder that can change with the increase and decrease of oil reserve in the atmospheric pressure lower volume on oil cylinder 3.Twitch handle 9 during work, plunger 10 is raised, with the fluid in the oil storage cylinder through boiler check valve 12 inspiration small oil tanks, meanwhile, because oil storage cylinder is flexible, along with the minimizing of oil reserve, oil storage cylinder 6 is under atmospheric pressure and produce recessed to distortion that volume is reduced, make fluid be in full state all the time, thereby guarantee jack under any heeling condition, can not occur influencing use less than oil because of the fluid and the oil-sucking hole on the base of oil storage cylinder from suction.When handle when the bottom, plunger 10 moves down, and fluid is pressed into load oil cylinder through boiler check valve 15, with plunger 8 jack-up, the process of finishing the work.During off-load, as long as cone valve 17 is back-outed, make oil return line 16 unimpeded, spring 5 moves down plunger and resets, and in the oily backflow oil cylinder, cylinder body is also protruding in the original volume of distortion recovery along with the increase of fluid.
Fig. 2 is the cutaway view of the demonstration another kind of form of the present invention conceived according to above-mentioned principle.
Flexible oil storage cylinder can add the hard protective case.
Flexible cylinder type universal hydraulic jack compared with prior art has the wide advantage of range of use in the technical field under the present invention, can replace the expensive screw jack of heavy valency on a lot of occasions.
Claims (1)
- The universal hydraulic jack a kind of by base 1 and the load oil cylinder 3 that is fixed on the base 1, that small oil tank 11 and the flexible oil storage cylinder 6 that links to each other with base are formed is characterized in that oil storage cylinder is to adopt the flexibility material to make; The valve of the boiler check valve on the oil circuit is to adopt spring constraint; Be connected with boiler check valve 12 by oil circuit 13 between small oil tank 11 and the oil storage cylinder 6; Be connected with cone valve 17 by oil circuit 16 between oil storage cylinder 6 and the load oil cylinder 3; Be connected with oil circuit 14 by boiler check valve 15 between load oil cylinder 3 and the oil cylinder 11.
