Abstract

The utility model discloses a hand-operated and electric oil jack which comprises an oil jack main body. The oil jack main body is provided with a hand-operated plunger pump and a miniature DC motor, wherein the miniature DC motor is connected with a speed reducer which is connected with a crank disk and the crank disk is connected with a connecting rod which is connected with an electric plunger pump. A torque balance spring is arranged in the electric plunger pump, and the speed reducer is a planetary gear speed reducer. The utility model has the advantages of strong lifting capacity, compact structure, small dimension, light weight, low cost, high flexibility, reliable operation, one machine with dual purposes, etc.

Description

Manually, electric dual-purpose oil jack

Technical field:

The utility model relates to a kind of oil jack, particularly a kind of manual, electric dual-purpose oil jack.

Technical background:

In actual life, on the way change tire to automobile is the chaufeur pain in the neck always, especially in the extremely hot summer and the winter of severe cold.What usually change that tire adopts to automobile is manually operated oil jack, this jack functional reliability height, and volume is little, and is easy to carry, but its hoisting speed is slow, the operation effort.Along with technology and expanding economy, the electric oil pressure jack has progressed into market, and this electric oil pressure jack utilizes the battery power on the car to start, and compares with manually operated oil jack, and its hoisting speed is fast, rapid operation.But in existing electric oil pressure jack, the functional reliability of mechanical type electric oil pressure jack is poor, and hoisting speed is slower, and cost height, noise are big when the electric oil pressure jack adopts geared oil pump, when with plunger pump,, be not easy to carry and use because of deceleration system makes its scantling of structure excessive.And for various electric oil pressure jacks,, chaufeur and the rider who makes the field change tire is in embarrassed condition in case its electrical motor and driving system break down.

Summary of the invention:

The purpose of this utility model is: provide that a kind of compact conformation, cost are low, reliable operation manually, the electric dual-purpose oil jack, to overcome above-mentioned the deficiencies in the prior art.

The utility model is to constitute like this: it comprises oil jack main body (8), hand piston pump (1) and DC micromotor (2) are housed on oil jack main body (8), DC micromotor (2) links to each other with retarder (7), retarder (7) be that crank disc (6) links to each other, crank disc (6) links to each other with connecting rod (5), and connecting rod (5) links to each other with electrical plunger pump (4).

Equilibrium of torques spring (3) is housed in electrical plunger pump (4).

Retarder (7) is an epicyclic reduction gear.

Owing to adopted technique scheme, the rotating speed and the epicyclic reduction gear of torque on coaxial line of DC micromotor output are transformed into slow speed of revolution, high pulling torque output, the piston crank mechanism of forming via crank disc and connecting rod will rotatablely move and change reciprocal straight-line motion into, promote and the interior plunger work done of pulling electrical plunger pump, thereby drive the jack action.Because the equilibrium of torques spring has been installed in electrical plunger pump, be compressed during its plunger backhaul oil suction in electrical plunger pump, stored power, worked as " pulse " phenomenon that the plunger backhaul is in no-load run thereby overcome DC micromotor to the driving system of connecting rod; When electrical plunger pump was pressed oil, the power that the equilibrium of torques spring stores was released, and has increased the jacking capacity of jack, and under same load, can correspondingly reduce the power of DC micromotor or the transmitting ratio of deceleration system.And adopt planetary wheel as retarder, because the alignment of itself and DC micromotor, crank disc, can make electronic deceleration system compact conformation, size is little, in light weight, to reduce the volume of whole oil jack, easy to carry and use, and also its cost also uses the electric oil pressure jack of geared oil pump low.And when in use breaking down when DC micromotor or by the driving system that epicyclic reduction gear, crank disc, connecting rod and electrical plunger pump are formed, can utilize hand piston pump to carry out M/C independently, continue the top car, removed the trouble and worry that chaufeur uses electronic jack.So the utility model is compared with prior art, and it is strong that it has hoisting capacity, compact conformation, and size is little, and is in light weight, and cost is low, and alerting ability is strong, reliable operation, but advantages such as dual-use.

Description of drawings:

Accompanying drawing 1 is a structural representation of the present utility model.

The specific embodiment:

Embodiment of the present utility model: as shown in Figure 1, on the base of oil jack main body (8), load onto hand piston pump (1) and DC micromotor (2), then epicyclic reduction gear (7) is linked to each other with DC micromotor (2), the power take-off shaft of epicyclic reduction gear (7) is linked to each other with crank disc (6), crank disc (6) is linked to each other with connecting rod (5), connecting rod (5) links to each other with electrical plunger pump (4), and loads onto equilibrium of torques spring (3) get final product in electrical plunger pump (4).Wherein DC micromotor (2) is arranged with epicyclic reduction gear (7) coaxial line, power driven system that DC micromotor (2), epicyclic reduction gear (7) and electrical plunger pump (4) are formed and the coexistence of the manual operation system of hand piston pump (1), and separate.The axial line of DC micromotor (2) and epicyclic reduction gear (7) can be the same with the axial line of oil jack main body (8) vertical and parallel, also 90 ° of layouts each other, and hand piston pump (1) can be arranged in the optional position on the horizontal surface.
