Abstract
The utility model relates to a hydraulic jack for a motorcar, and the utility model is the improvement of an existing hydraulic jack. The utility model is mainly composed of a manual pump, a jacking oil cylinder, a high-pressure oil-delivery hose, pipe joints, a stop valve, etc. The utility model separates the manual pump from the jacking oil cylinder; thus, a safety problem in the application of a jack is solved; at the same time, the advantages of the jack of simple structure and convenient use are maintained.
Description
The utility model belongs to a kind of vehicle maintenance and repair and the hydraulic jacking device of rescuing usefulness, is the improvement to existing jack.
Existing car jack generally is made up of force pump and jacking cylinder, they are combined, though this jack is simple in structure, easy for operation, but because operating personal must be operated in the jacking position, in case meet accident in the jacking process, then as easy as rolling off a log generation safety misadventure jeopardizes the life of operating personal.
The purpose of this utility model is existing jack is improved, and its oil pump is separated with jacking cylinder, has both kept the advantage of jack, can overcome its deficiency at secure context again.
The purpose of this utility model is achieved by following technological approaches: a kind of automobile hydraulic jacking device, have manual pump, jacking cylinder, high pressure oil hose, adaptor union and shutoff valve, fluid transmits between manual pump and jacking cylinder by shutoff valve, adaptor union and high pressure oil hose, wherein:
A, manual pump comprise fuel tank, rocking handle, lever support, plunger, O shape
A, manual pump ［ 1 ］ comprises fuel tank ［ 1-2 ］; rocking handle; lever support ［ 1-5 ］; plunger ［ 1-6 ］; O-ring seals ［ 1-7 ］; little bifurcation shape seal ring ［ 1-8 ］; oil-feed ball check valve ［ 1-9 ］; fuel-displaced ball check valve ［ 1-10 ］; joint ［ 1-11 ］ and retracing spring ［ 1-15 ］; fuel tank ［ 1-2 ］ is provided with filler plug ［ 1-3 ］; plunger ［ 1-6 ］ is gone up the termination rocking handle; rocking handle one end connects retracing spring ［ 1-15 ］; oil-feed ball check valve ［ 1-9 ］ and fuel-displaced ball check valve ［ 1-10 ］ are located at respectively on the oil inlet and oil outlet of plunger ［ 1-6 ］ bottom, and shutoff valve ［ 7 ］ is located at manual pump ［ 1 ］ and upward and with fuel tank ［ 1-2 ］ is communicated;
B, jacking cylinder ［ 2 ］ are made up of with little bifurcation shape seal ring ［ 2-9 ］, exclusion seal ［ 2-2 ］ jacking block ［ 2-1 ］, cylinder body ［ 2-3 ］, adjusting screw(rod) ［ 2-4 ］, base plate ［ 2-8 ］, piston rod ［ 2-10 ］, locknut ［ 2-11 ］ and O-ring seals ［ 2-5,2-6 ］, hole, its oil inlet and outlet ［ 2-7 ］ connects with adaptor union ［ 4 ］, jacking block ［ 2-1 ］ is affixed with adjusting screw(rod) ［ 2-4 ］, and adjusting screw(rod) ［ 2-4 ］ is threaded onto in the piston rod ［ 2-10 ］.
When need jacking automobile, close shutoff valve ［ 7 ］, open shutoff valve ［ 8 ］, shake the rocking handle of force pump ［ 1 ］, fluid just enters in the jacking cylinder ［ 2 ］ by oil-feed ball check valve ［ 1-10 ］, joint ［ 1-11 ］, shutoff valve ［ 8 ］, adaptor union ［ 4 ］, high pressure oil hose ［ 3 ］ and adaptor union ［ 4 ］ continuously from fuel tank ［ 1-2 ］, with piston rod ［ 2-10 ］ jack-up, thereby with the automobile jacking to desired height, when putting down, only need open shutoff valve ［ 7 ］, fluid just at automobile certainly
Seal ring, little bifurcation shape seal ring, oil-feed ball check valve, fuel-displaced ball check valve, joint and retracing spring, termination rocking handle on the plunger; rocking handle one end connects retracing spring; oil-feed ball check valve and fuel-displaced ball check valve are located at respectively on the oil inlet and oil outlet of plunger bottom; manual pump is provided with the shutoff valve of an oil return, and this shutoff valve communicates with fuel tank;
B, jacking cylinder are made up of with little bifurcation shape seal ring, exclusion seal jacking block, cylinder body, adjusting screw(rod), base plate, piston rod, locknut and two O-ring seals, holes, its oil inlet and outlet connects with adaptor union, jacking block and adjusting screw(rod) are affixed, and adjusting screw(rod) is threaded onto in the piston rod.
The utility model had both kept the advantage of existing jack, separated with jacking cylinder owing to its oil pump simultaneously, thereby had improved its processing safety greatly.Description of drawings:
