Abstract

The utility model relates to an electric jack which comprises a jack with a transmission screw, wherein, one end of a left lower raised arm and one end of a right lower raised arm of the jack are hinged in a base, the other ends of the left lower raised arm and the right lower raised arm are respectively connected with a left upper raised arm and a right upper raised arm through a left torsion shaft hinge and a right torsion shaft hinge, the transmission screw is inserted through screw holes of the left torsion shaft hinge and the right torsion shaft hinge, one end of the transmission screw is connected with a rotary shaft of a reducer, the reducer is in transmission connection with a motor; the left upper raised arm and the right upper raised arm are hinged with each other through a pivoted bolt and respectively extend out the same length outward at the hinge, the tail ends of the upper ends of the left upper raised arm and the right upper raised arm are respectively connected with a left jack-up arm and a right jack-up arm though a pivoted bolt hinge, the other ends of the left jack-up arm and the right jack-up arm are respectively hinged in a same connecting block. With the electric jack of the utility model, the length of a lower end arm of the hinged pivoted bolt of the left upper raised arm and the right upper raised arm is greater than that of an upper end arm, thereby ensuring that the jacking force produced by the left jack-up arm and the right jack-up arm are greater than that of the left upper raised arm and the right upper raised arm. The utility model has a simple and novel structure, easy manufacture, convenient carrying, safety and reliability, and greatly contributes to the popularization and the implementation.

Description

Electronic jack

One, technical field:

The utility model relates to the jack field, particularly a kind of electronic jack.

Two, background technology:

At present, all will use jack aspect the repairings such as automobile, widely used jack has hand-hydraulic formula jack, hand screw mandrel formula jack, hand-hydraulic formula jack is relatively heavier, hand screw mandrel formula jack is lighter, but for will support than the weight body time, not only requires great effort but also time-consuming.The hand jack keystone configuration of small portable formula is a scissors hold-down arm, cross-drive screw rod in the scissors hold-down arm and the cranker rocking bar composition that is connected, this scissors screw mandrel jack is big because of operation labour intensity, the electronic jack that defectives such as effect is low, and safety is relatively poor are equipped with motor replaces.The Chinese patent patent No. is that CN99241854.2's " the electronic jack of through-coupling formula ", the patent No. is that " the electronic jack " of CN02232962.5 and " shears-type electric jack " that the patent No. is CN200520037563.4 are the shaking jack and are equipped with motor as power and cooperate reductor to realize electronic control, for use has brought convenience.But it is all not really desirable that the related product of above-mentioned patent is considered on raising weight height and laborsaving degree.

Three, utility model content:

The utility model is to overcome the deficiency that prior art exists, and designs and produce a kind of electronic jack.

Technical scheme:

A kind of electronic jack, comprise that one has the jack of drive screw, lifting arm one end about described jack down is hinged in the base, about lift down the arm other end with about go up the act arm respectively by about turn round pivot hinge and be connected, drive screw through about turn round the axle screw in, drive screw one end connects the reductor rotating shaft, reductor is connected with drive of motor, about go up to lift arm and be hinged by the axle bolt, and the equal length that stretches out respectively in the hinged place, arm was lifted on the top about the upper end end of lifting arm on about described connected by an axle bolt hinge respectively, and the other end that arm is lifted on top about this is hinged on respectively in the same contiguous block.

Go up about described and lift arm, the lower arm of its jointed shaft bolt is grown up in jointed shaft bolt top brachium.

Described reductor is a reducing gearbox, or is that turbine cooperates the speed reduction gearing of forming with worm screw.

One end is turned round axle and is fixed on the locating plate by toggle, and this locating plate is fixed on the reductor.

The beneficial effects of the utility model:

1, electronic jack of the present utility model, it is hand, very easy to use to adopt motor to replace, and not only is fit to the male sex and uses, and also is fit to the women and uses.

2, electronic jack of the present utility model, about on lift the arm end and be provided with about the top lift arm, thereby effectively increased the height of jack institute jacking, make launch and folding after diff-H increase, for use has brought convenience.

3, electronic jack of the present utility model, about go up to lift arm jointed shaft bolt lower end brachium greater than the upper end brachium, thereby to about on lift arm and apply under the situation of same power, take apart from principle according to lever force-saving, about making the top lift arm produce top power greater than about go up the top power of act arm.

4, electronic jack of the present utility model, novelty simple in structure, lower cost is made easily, and is easy to carry, safe and reliable, is beneficial to very much promotion and implementation.

Four, description of drawings:

Fig. 1 is one of electronic jack mounting structure scheme drawing;

Fig. 2 is the perspective view of Fig. 1;

Fig. 3 is the Facad structure scheme drawing of Fig. 2;

Fig. 4 is two of an electronic jack structure scheme drawing.

Five, specific embodiments:

Embodiment one: referring to Fig. 1, Fig. 2, Fig. 3, a kind of electronic jack, comprise that one has the jack of drive screw 11, lifting arm 3 one ends about described jack down is hinged in the base 5, about lift down arm 3 other ends with about go up lift arm 2 respectively by about turn round 4 hinge and be connected, drive screw 11 through about turn round in axle 4 the screw, drive screw 11 1 ends connect reductor 12 rotating shafts, reductor 12 is in transmission connection with motor 7, going up act arm 2 wherein is hinged by axle bolt 10, and the equal length that stretches out respectively in the hinged place, the upper end end of lifting arm 2 on about described connects two tops by axle bolt 10 hinges respectively and lifts arms 1, the other end of these two top act arms 1 is hinged on respectively in the same contiguous block 6, is fixed with top pad 7 on this contiguous block 6.Going up the lower arm of lifting arm 2 jointed shaft bolts about described grows up in jointed shaft bolt top brachium.Described reductor 12 is a reducing gearbox, or is that turbine cooperates the speed reduction gearing of forming with worm screw.An end of the present utility model is turned round axle 4 and is fixed on the locating plate 9 by toggle 8, and this locating plate 9 is fixed on the reductor 12.

Embodiment two: referring to Fig. 4, number identically with embodiment one, meaning is identical, does not repeat, and different is: about go up and lift arm 2 for interlaced with each other hinged, about to lift arm 1 also be the interlaced with each other hinged of corresponding matching on the top.
