Abstract

The utility model relates to a mini electro-hydraulic jack used by automobiles and belongs to crane machinery field. The prior jack jacks an object by shaking driving the oil tank rising, and is purely hand operation thus is not convenient for ladies and is wasting force, while the utility model is a jack that adopts direct current. The electric jack consists of a gearbox body, a bracket assembly, a controlling electromotor, an igniter plug, a control panel and a jack-up bracket, the main points are that the inlet end link of the direct current power of the control electromotor connects with the control panel and the inlet end link of the power of the control panel connects with the igniter plug, while the igniter plug connects with the igniter socket of a car cab. The utility model has the advantages of small volume thus is convenient for carrying, and the function that the electromotor start the jack by leading out power directly from the igniter socket of the car cab, thus is convenient and widely for using and has high value.

Description

The electronic jack of miniature car

Technical field

The utility model relates to the elevator machinery field.

Background technology

At present, the shaking jack is one of miniature car instrument commonly used, and it is simple in structure, and applicable surface is wider, can implement the jack-up of object in less space, and its weak point is pure manual operations, and the Ms operates and owes just the gas of requiring great effort relatively.

Summary of the invention

The utility model is to provide a kind of electronic jack of miniature car that adopts direct supply to this area, to solve the still irrealizable problem of shaking jack commonly used.Now in conjunction with the following drawings, its feature is described as follows:

The electronic jack of a kind of miniature car, this electronic jack mainly is made of gearbox body, bracket assembly, control motor, firing unit plug, control desk, jack-up support, and its feature is as follows:

A) the dc supply input line of control motor 17 is connected with control desk 24, and the power input line of control desk is connected with firing unit plug 23, and the firing unit plug is the firing unit socket bonded assembly with automobile cab;

B) control motor 17 is connected to a fixed in motor frame 6 with gearbox body 14;

C) gearbox body 4 is fixed on the bracket assembly 16;

D) bracket assembly 16 is provided with support 18, lower bracket 21, upper bracket and is hinged with top 19, and lower bracket is hinged with lower connecting base 22;

E) end of screw mandrel 12 is connected with the output shaft of gearbox body 4, and screw mandrel is the negative thread adapter sleeve that runs through upper bracket 25,21 pivotally attached bolts of lower bracket.

19, two hinged lower connecting bases 22 in lower bracket 21 both ends in hinged top, two upper bracket 18 both ends of described jack-up support 25.

The advantage of the jack of this structure is that volume is urinated in carrying with car, directly draws the function that current and power supply can be implemented electronic starting jack from the firing unit socket of automobile cab, and is easy to use, widely applicable, and higher using value is arranged.

Description of drawings

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the elevational schematic view of Fig. 1;

Fig. 3 is the utility model embodiment scheme drawing.

Sequence number among the figure and title: 1, fix screw, 2, positioning retainer ring, 3, ball, 4, gearbox body, 5, fix screw, 6, motor frame, 7, gear, 8, antifriction-bearing box, 9, gear, 10, nest, 11, key, 12, screw mandrel, 13, bearing, 14, gear, 15, fix screw, 16, bracket assembly, 17, the control motor, 18, upper bracket, 19, the top, 20, bolt, 21, lower bracket, 22, lower connecting base, 23, the firing unit plug, 24, control desk, 25, the jack-up support.

The specific embodiment

Embodiment is example to use.The spigot of firing unit plug 23 directly is inserted into the igniting socket aperture of automobile cab, and this igniting socket also claims the socket that lights a cigarette, and is for direct supply.By being provided with rising button or decline, stopping key on the control desk 24.As pressing rising button, control motor 17 rotates to the cw mode, and the output shaft of control motor transmits the gear 9 of moment to the gearbox body 4.Be connected with screw mandrel 12 by the output shaft in the gearbox body screw mandrel is rotated.The both ends jack-up support 25 of screw mandrel is connected, articulated top 19 between two upper brackets 18 of jack-up support; The in addition both ends of these two supports with by 20 bonded assembly negative threads of bolt adapter sleeve, the both ends of two lower brackets 21 are hinged, the both ends in addition of two lower brackets 21 then are hinged with the cooresponding lower connecting base 22 in top.The screw mandrel that rotates advances to the center of top so drive upper and lower support because of the connected effect of negative thread adapter sleeve that upper bracket, lower bracket, bolt are arranged, drives and comes directly towards rising.If the center opposite orientation to the top is moved, the top then descends, and this displacement must be realized by the opposite rotation direction of control motor.
