Abstract
The utility model relates to a jack. The utility model has the technical proposal that a lifting mechanism consisting of a steel sleeve and a diving piston is connected with a pressuring system consisting of an oil tank and a pressuring piston by a high-pressure oil pipe; the steel sleeve and the pressuring piston of the pressuring system are vertically (or horizontally) fixed on a chassis; the top of the pressuring piston is connected horizontally with a stressing pole; the short end of the stressing pole is connected with a fulcrum on one side, while the other end of the stressing pole is fixed on a pedal; an oil inlet communicated with the oil tank and an oil outlet communicated with the high-pressure oil pipe are arranged at the bottom of the steel sleeve; a one-way valve is respectively arranged in the oil inlet and the oil outlet; a high-pressure valve can be used for communicating or blocking the high-pressure oil pipe and the oil tank; a spring body is arranged between the top of the steel sleeve and the pressuring piston; two ends of the spring body respectively act with the steel sleeve and the stressing pole; compared with the all-in-one-shaped jack, the jack of the utility model has the advantages of convenient operation, flexible use, high lifting height and safe operation.
Description
One, technical field: the utility model relates to a kind of jack.
Two, background technology: at present the jack that uses mostly is the integral type design, in use needs people's operation under by the lifting weight, and can not level use, and makes troubles and dangerous to the user.
Three, summary of the invention: the utility model is exactly the above-mentioned technical matters that exists at existing jack integrated design, and a kind of jack of split type use is provided.
Its technical scheme is: foot-operated oil jack, lifting mechanism of being made up of steel bushing, the piston of rushing to summit and the pressing mechanism of being made up of oil cylinder, pressurizing piston connect to form by high pressure fuel pipe.The steel bushing of pressing mechanism and pressurizing piston are vertically fixed on the base, the top, horizontal of pressurizing piston connects a boosting-rod, the short end of boosting-rod is connected on the fulcrum of a side, the other end is fixed with stretcher, oil inlet that is communicated with oil cylinder and the oil outlet that is communicated with high pressure fuel pipe are arranged in the bottom of steel bushing, in oil outlet and oil inlet, be separately installed with check valve, between high pressure fuel pipe and oil cylinder, be communicated with or close by high pressure valve.Between steel bushing top and pressurizing piston, be with spring body, the spring body two ends respectively with steel bushing and boosting-rod effect.
Another technical scheme is: the steel bushing of pressing mechanism and pressurizing piston are horizontally fixed on the base, on the outer end of pressurizing piston, tiltedly fix a connecting rod, one end of boosting-rod is connected on the fulcrum of steel bushing top, the other end is fixed with stretcher, between steel bushing one end and pressurizing piston, be with spring body, the other end at steel bushing has oil inlet that is communicated with oil cylinder and the oil outlet that is communicated with high pressure fuel pipe, in oil outlet and oil inlet, be separately installed with check valve, between high pressure fuel pipe and oil cylinder, be communicated with or close by high pressure valve.
Jack of the present utility model is compared with the integral type jack to have easy to operately, use flexibly, the lift height height, but and multi-angle use, operation does not have dangerous.
Four, description of drawings:
Fig. 1 is a kind of structural representation of the present utility model;
Fig. 2 is an another kind of structural representation of the present utility model.
Five, the specific embodiment:
Embodiment 1: contrast Fig. 1, and foot-operated oil jack, lifting mechanism of being made up of steel bushing 2, the piston 1 of rushing to summit and the pressing mechanism of being made up of oil cylinder 10, pressurizing piston 9 connect to form by high pressure fuel pipe 3.The steel bushing 12 of pressing mechanism and pressurizing piston 9 are vertically fixed on the base 14, the top, horizontal of pressurizing piston 9 connects a boosting-rod 7, the short end of boosting-rod is connected on the fulcrum 5 of a side, the other end is fixed with stretcher 8, oil inlet 11 that is communicated with oil cylinder 10 and the oil outlet 13 that is communicated with high pressure fuel pipe are arranged in the bottom of steel bushing 12, in oil outlet 13 and oil inlet 11, be separately installed with check valve, between high pressure fuel pipe 3 and oil cylinder 10, be communicated with or close by high pressure valve 6.Be with spring body 4 between steel bushing 12 tops and pressurizing piston 9, spring body 4 two ends act on steel bushing 12 and pressurizing piston 9 respectively.
Embodiment 2: contrast Fig. 2, the steel bushing 12 of pressing mechanism and pressurizing piston 9 are horizontally fixed on the base 14, on the outer end of pressurizing piston 9, tiltedly fix a connecting rod 15, one end of boosting-rod 7 is connected on the fulcrum of steel bushing top, the other end is fixed with stretcher 8, between steel bushing 12 1 ends and pressurizing piston 9, be with spring body 4, the other end at steel bushing 12 has oil inlet 11 that is communicated with oil cylinder 10 and the oil outlet 13 that is communicated with high pressure fuel pipe 3, in oil outlet 13 and oil inlet 11, be separately installed with check valve, between high pressure fuel pipe 3 and oil cylinder 10, be communicated with or close by high pressure valve 6.
During use, high pressure valve is closed, constantly jam on boosting-rod, the lifting thing is brought up to desired height get final product with pin.After operation is finished, rotate high pressure valve, high pressure oil flows back to oil cylinder, and weight recovers the home position.
