Description
Technical field
The utility model relates to a kind of scissors-type jack, relates in particular to a kind of electric-hand driven two-purpose scissors-type jack.
Background technology
At present, the scissors-type jack that roadlice carries with car is a manually operated, its basic structure is: a pair of act arm is connected by forward and backward bearing pin with pair of support arms, the joint of lifting arm is equipped with platform, the joint of hold-down arm is equipped with base, one drive screw passes through forward and backward bearing pin, offers the tapped bore that cooperates with drive screw on rear pin shaft, and the drive screw rear end is provided with rocker sleeve.During use, rocking bar is penetrated rocker sleeve, rotating rocker just can drive the drive screw rotation of jack, and the rear pin shaft that is enclosed within on the drive screw will be made axial motion on the axis direction of drive screw.Like this, lift arm and hold-down arm and under the effect of the rear pin shaft of axial motion, open or close up, drive platform and rise or descend, thereby hold up or put down roadlice around forward and backward bearing pin.
In actual use, because must be hand-manipulated, muscle power expended very much; In addition, jack often places under the roadlice chassis, and especially in the top lifting stage, jack is only started working from about ten centimeters height, so the operator can only stay outside the car and the centre of body weight ground proximity is operated, and is very inconvenient.On rainy day or muddy road, operation is difficulty especially.
Summary of the invention
Scissors-type jack must be hand-manipulated in the prior art in order to overcome, awkward deficiency, simultaneously consider that again Vehicular power supply system hinders the reality that can't power for some reason under some situation, the utility model provide a kind of scantling of structure little, use easily, install electric-hand driven two-purpose scissors-type jack easily.
The technical scheme in the invention for solving the technical problem is: a kind of electric-hand driven two-purpose scissors-type jack, comprise a pair of act arm and pair of support arms, platform, base, drive screw and retarder motor, described platform is by being mounted on the upper end of described act arm, described base is by being mounted on the lower end of described hold-down arm, the front end of described act arm and the front end of described hold-down arm, before the rear end of described act arm and the rear end of described hold-down arm are passed through respectively, rear pin shaft connects, described drive screw passes through described rear pin shaft, offer cavity on the described rear pin shaft and driving nut is installed in cavity, offer the screw thread that cooperates with described drive screw on the described driving nut, the output shaft of described retarder motor stretches out from front end cover, and described output shaft is connected with the front end of described drive screw by connecting bushing.
Further, the set-up mode of described retarder motor has three kinds: a kind of be described retarder motor rear side housing with described before bearing pin be connected, described retarder motor accumbency this moment between described act arm and described hold-down arm, on the axial location, the inboard of the fuselage of described retarder motor and front end cover and output shaft bearing pin before described, promptly before described between bearing pin and the rear pin shaft; A kind of be described retarder motor fuselage with described before bearing pin is connected the outside of rear side housing bearing pin before described of described retarder motor at this moment, the inboard of the front end cover of described retarder motor and output shaft bearing pin before described; Another kind is that the front end cover of described retarder motor is connected with described preceding bearing pin, and the fuselage of described retarder motor and rear side housing are positioned at the outside of described preceding bearing pin at this moment.
Further, the output shaft line of centers of described retarder motor by bearing pin line of centers before described and with described drive screw on same axis.
Further again, a tight fixed bolt also is installed on the described rear pin shaft, be used for fastening described rear pin shaft and power-transfer clutch.
Also further, described act arm and described hold-down arm have the cavity that is used to hold described retarder motor in the corresponding position of described retarder motor position.
The utility model is rotated by retarder motor-driven drive screw in use, the drive screw of rotation will drive driving nut simultaneously and rear pin shaft is made axial motion on the axis direction of drive screw, like this then lift arm and hold-down arm and under the combined action of driving nut and rear pin shaft, open or close up around forward and backward bearing pin, thus hold up or put down roadlice.
When Vehicular power supply system hinders can't power the time for some reason, unscrew the tight fixed bolt on the rear pin shaft, driving nut promptly separates with rear pin shaft.Put rocking bar and drive the driving nut rotation, driving nut will drive rear pin shaft and make axial motion on the axis direction of drive screw, realize manual function.
The beneficial effects of the utility model are: 1. owing to use the retarder motor to replace manual work, convenient and swift, labour intensity is low.2. because retarder motor diameter and limited length, and between preceding bearing pin and rear pin shaft or the preceding bearing pin outside, do not influence height and width dimensions after jack closes up, influence the length dimension after jack closes up hardly yet, be convenient to place and carry.3. on rear pin shaft, be provided with separable driving nut, even still can handwork under power free situation.
