Utility model content
The purpose of this utility model is, provides a kind of motor-driven jack.The utility model can realize motorized motions lifting, has succinctly easy to use, and rising or falling speed is stablized, without the need to changing hydraulic pressure wet goods advantage.
The technical solution of the utility model: a kind of motor-driven jack, comprise base, be hinged with lower-left pivoted arm and bottom right pivoted arm above base, lower-left pivoted arm is hinged with upper left pivoted arm, bottom right pivoted arm is hinged with upper right pivoted arm, the hinged setting in top of described upper left pivoted arm and upper right pivoted arm; Described upper left pivoted arm and pivoted arm hinged place, lower-left and upper right pivoted arm and pivoted arm place, bottom right are provided with tapped bore, an elevating screw is equipped with in described tapped bore, the end of elevating screw is provided with a worm gear, and worm gear center is provided with tapped bore, and elevating screw is located on tapped bore; The outside of described worm gear is provided with screw thread and is engaged with rotary screw, and the end of rotary screw is provided with one from gear, has main gear from gears meshing, and main gear is connected with the mouth of the motor be fixed on base.
In above-mentioned motor-driven jack, the other end of described elevating screw is also provided with the groove that can manually screw.
In above-mentioned motor-driven jack, described elevating screw comprises main elevating screw and secondary elevating screw, and the junction of main elevating screw and secondary elevating screw is between worm gear and the hinge-point of lower-left pivoted arm and upper left pivoted arm; Hollow in described main elevating screw, secondary elevating screw inserts in main elevating screw, and main elevating screw inside is provided with 2 road set collars, and secondary elevating screw outside is provided with the shaft shoulder, and the shaft shoulder is between 2 road set collars; Main elevating screw is provided with through hole, and the shaft shoulder is provided with fixed orifice, is inserted with connecting shaft rivet in the through hole of main elevating screw, and the end of connecting shaft rivet is inserted in the fixed orifice of the shaft shoulder.
Compared with prior art, the utility model by motor through main gear, rotate from gear drive rotary screw, and drive worm gear to rotate, because worm gear and elevating screw are threaded, therefore when worm gear rotates, elevating screw also rotates, and drives upper left, lower-left, upper right and bottom right pivoted arm to rotate, and realizes lifting.The utility model can realize motorized motions lifting, has succinctly easy to use, and rising or falling speed is stablized, without the need to changing hydraulic pressure wet goods advantage.As further preferably, be also provided with the groove that can manually screw at the other end of elevating screw, therefore can realize manual and electric two kinds operation.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the fundamental diagram of worm gear;
Fig. 3 is the connection diagram of main elevating screw and secondary elevating screw.
Detailed description of the invention
Below in conjunction with embodiment, the utility model is described in further detail, but not as to restriction of the present utility model.
Embodiment: a kind of motor-driven jack, form as depicted in figs. 1 and 2, comprise base 1, lower-left pivoted arm 2 and bottom right pivoted arm 3 is hinged with above base 1, lower-left pivoted arm 2 is hinged with upper left pivoted arm 4, bottom right pivoted arm 3 is hinged with upper right pivoted arm 5, the hinged setting in top of described upper left pivoted arm 4 and upper right pivoted arm 5; Described upper left pivoted arm 4 and lower-left pivoted arm 2 hinged place and upper right pivoted arm 5 and bottom right pivoted arm 3 place are provided with tapped bore, an elevating screw 6 is equipped with in described tapped bore, the end of elevating screw 6 is provided with a worm gear 7, and worm gear 7 center is provided with tapped bore, and elevating screw 6 is located on tapped bore; The outside of described worm gear 7 is provided with screw thread and is engaged with rotary screw 8, and the end of rotary screw 8 is provided with one from gear 9, is engaged with main gear 10 from gear 9, and main gear 10 is connected with the mouth of the motor 11 be fixed on base 1.The other end of described elevating screw 6 is also provided with the groove 12 that can manually screw.As shown in Figure 3, described elevating screw 6 comprises main elevating screw 13 and secondary elevating screw 14, and the junction of main elevating screw 13 and secondary elevating screw 14 is between worm gear 7 and the hinge-point of lower-left pivoted arm 2 and upper left pivoted arm 4; Hollow in described main elevating screw 13, secondary elevating screw 14 inserts in main elevating screw 13, and main elevating screw 13 inside is provided with 2 road set collars 15, and secondary elevating screw 14 outside is provided with the shaft shoulder 16, and the shaft shoulder 16 is between 2 road set collars 15; Main elevating screw 13 is provided with through hole 17, and the shaft shoulder 16 is provided with fixed orifice 18, is inserted with connecting shaft rivet 19 in the through hole 17 of main elevating screw 13, and the end of connecting shaft rivet 19 is inserted in the fixed orifice 18 of the shaft shoulder 16.
