Also the someone has proposed the electric scissor jack, as the patent No. is that 99241854.2 Chinese utility model patent discloses the electronic jack of a kind of through-coupling formula, this electronic jack has the electro-motor that has reducing gearbox of peripheral hardware, the output shaft of the electro-motor of this peripheral hardware is connected with the drive screw of jack, and is used to connect and has torsion between the bearing pin of lifting arm and following trailing arm and this electro-motor and allay device.Also the shortcoming of Cun Zaiing is: because electro-motor is an external, cause the integral structure size of jack to become big, be not easy to carry, and function is also very single, can only use as jack.
(3) summary of the invention
In order to overcome the deficiency that electric scissor jack structure size in the prior art is big, be not easy to carry, the utility model provides a kind of scantling of structure electric scissor jack little, easy to carry.
The technical scheme in the invention for solving the technical problem is:
A kind of electric scissor jack, comprise a pair of upward act arm and a pair of following trailing arm that base is installed that lifting platform is installed, the front end of last act arm and the front end of following trailing arm, before the rear end of last act arm is passed through respectively with the rear end of following trailing arm, rear pin shaft connects, also comprise and be used to drive the drive screw of lifting arm and following trailing arm, the one speed reducer motor is lifted arm and described down between the trailing arm on described, the rear side housing of described retarder motor and described rear pin shaft are hinged, the output shaft of described retarder motor stretches out from front end cover, described output shaft front end is connected with described drive screw rear end, bearing pin offers tapped bore before described, and described drive screw cooperates with described tapped bore.
Further, described drive screw front portion also is equipped with a rocking bar axle sleeve.
Further, described drive screw front end also is equipped with ut socket.
Further, described upward act arm and described trailing arm down have the cavity that is used to hold described retarder motor in the corresponding position of described retarder motor position.
Further again, the output shaft of described retarder motor and described drive screw are on same axis.
Also further, the affixed axle sleeve of the rear side housing of described retarder motor, described axle sleeve is enclosed within on the described rear pin shaft.
The utility model is rotated by retarder motor-driven drive screw in use, bearing pin was made axial motion before the drive screw of rotation will drive on the axis direction of drive screw, like this then go up to lift arm and following trailing arm and under the effect of preceding bearing pin, bend and open around forward and backward bearing pin, thus picking-up or put down roadlice.
The beneficial effects of the utility model are: 1. since the retarder motor between last act arm and following trailing arm, thereby reduced the integral structure size of jack greatly, be convenient for carrying.2. owing to being provided with the rocking bar axle sleeve, even under the situation that power supply can't be powered, still can use jack by hand in the drive screw front portion.3. owing to ut socket has been installed, use, be used for the removal nut so jack described in the utility model can also be worked as power-operated wrench at the drive screw front end.
