The beneficial effects of the utility model are: a kind of Potable car motor-driven jack that the utility model proposes, simple in construction, operation principle is clear, use motor, gear and the combined structure of worm drive, automobile self dc is utilized to input as the power supply of jack, the addition of emergency light structure ensure that jack can normally use in the case of light condition is poor, compared with traditional car jack, its structure is the most reasonable, hommization, improve operating accuracy, operate the simplest, carry the most more convenient, the work efficiency of equipment and safety have also been obtained and significantly promote, also reduce manufacturing cost and maintenance cost simultaneously.
Accompanying drawing explanation
Fig. 1 is this utility model overall structure schematic diagram.
In figure: base plate 1, fixed sleeving 2, chute 3, alignment pin 4, lower position switch 5, upper limit position switch 6, servomotor 7, retractable cable support 8, attaching plug 9, direction switch 10, handle 11, emergency light 12, driving gear 13, driven gear 14, rising bar 15, lifting screw 16, female flange dish 17, plane bearing 18, locating support 19, shell 20.
Detailed description of the invention
The utility model is described in further detail below in conjunction with the accompanying drawings:
As it is shown in figure 1, a kind of Potable car motor-driven jack, the servomotor 7 including base plate 1, being fixedly installed on base plate 1 and shell 20；nullFixed sleeving 2 also it is fixed with on base plate 1，Fixed sleeving 2 is arranged over the driven gear 14 of female flange dish 17，It is provided with, in the middle of driven gear 14, the lifting screw 16 that can be movable relatively，Lifting screw 16 moves up and down in fixed sleeving 2，The inside of lifting screw 16 is provided with the rising bar 15 that can be movable relatively，Female flange dish 17 is relatively rotated with fixed sleeving 2 by plane bearing 18，Fixed sleeving 2 cylindrical has vertical chute 3，It is provided with in chute 3 and is connected fixing alignment pin 4 with lifting screw 16，Fixed sleeving 2 outer wall upper end is provided with upper limit position switch 6，Lower end is provided with lower position switch 5，Alignment pin 4 moves up and down in chute 3 and touches bound bit switch，The groove of female flange dish 17 is provided with locating support 19，The lower section of locating support 19 is fixedly linked with the cylindrical tube wall of fixed sleeving 2，Servomotor 7 is arranged over driving gear 13，Driving gear 13 is connected with driven gear 14 transmission.
