Abstract
The utility model relates to an electric and hand-operated jack which comprises a screw-rod jack, wherein the hand-operated end of a screw rod of the screw-rod jack is a square shaft on which a turbine is sheathed, and a worm engaged with the turbine is fixed on a housing through a bearing and is fixed with a motor shaft; the left end of the housing is provided with a rectangular convex block which can be embedded in a clamping groove of a clamping base, and the clamping base is fixed to a pivot shaft on the hand-operated end of the screw-rod jack so as to prevent the housing from rotating relatively; a pin hole is arranged on the square shaft, and an opening pin is inserted in the pin hole so as to prevent the housing and the turbine from desquamating from the square shaft. The utility model has the advantages of high lifting speed, manpower saving, electric operation, hand operation, simple structure and convenient carrying and use.
Description
(1), technical field
The utility model relates to a kind of manual and electric dual-purpose jack.
(2), background technology
Small portable jack car is one of instrument of automotive servicing industry indispensability, but all is manually operated at present.For example hand screw type jack reaches by hand leading screw exactly vehicle jack-up is still put down, and using wastes time and energy.
(3), summary of the invention
In order to overcome the shortcoming of prior art, the utility model provides a kind of manual and electric dual-purpose jack, and it is fast that it not only works the speed of putting, and do not need the expense manpower, and manual, electric dual-purpose, and is simple in structure, uses easy to carry.
The technical scheme in the invention for solving the technical problem is: it comprises the screw type jack, the hand end of the leading screw of described screw type jack is a square shaft, be with turbine on the square shaft, with the turbine engaged worm by bearing fixing on shell, worm screw and motor shaft are fixed, the left end of described shell has the rectangle projection, projection can be embedded in the draw-in groove of deck, the hinge of deck and the hand end of screw type jack is fixed, can prevent that shell from relatively rotating, on the described square shaft pin-and-hole is arranged, be inserted with spring cotter in the pin-and-hole, come off from square shaft to prevent shell and turbine.
Because the screw type jack can drag with motor, so it is fast not only to work the speed of putting, does not need the expense manpower, and simple in structure, uses easy to carry.Unload turbine and motor, can manually realize manual, electric dual-purpose.
(4), description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the utility model front view;
Fig. 2 is the utility model birds-eye view.
(5), the specific embodiment
As shown in Figure 1, 2, the utility model comprises a screw type jack 2.The hand end of the leading screw 1 of described screw type jack 2 is a square shaft 11, is with turbine 9 on the square shaft 11, with turbine 9 engaged worm 8 by bearing fixing on shell 7, worm screw 8 is fixed with the output shaft of motor 6.The left end of described shell 7 has rectangle projection 5, and projection 8 can be embedded in the draw-in groove of deck 4, and deck 4 is fixing with the hinge 3 of screw type jack 2 hand ends, can prevent that shell 7 from relatively rotating.On the described square shaft 11 pin-and-hole is arranged, be inserted with spring cotter 10 in the pin-and-hole, come off from square shaft 11 to prevent shell 7 and turbine 9.
