The specific embodiment

Below in conjunction with accompanying drawing the specific embodiment is illustrated.

As shown in Figure 1 to Figure 3, the electronic jack of the utility model comprises base plate 1 and casing 2, in described casing, be provided with big gear wheel 8, inner screw 11, middle screw rod 9, interior support set 3, outer support set 4, one end of inner screw 3 is threaded with big gear wheel 8 centers, the hollow bulb of screw rod 9 during inner screw 11 is in, in the hollow wall of screw rod 9 be provided with screw thread and match with the outer screw thread of inner screw, inner screw 11 can spinning in and out in middle screw rod 9.Interior support set 3 inner hollow, its outer wall and outer support set 4 sockets, its inwall is provided with the screw thread that matches with middle screw rod 9 appearance screw threads, and interior support set 3 is linked in middle screw rod 9 skins, outer support set 4 be socketed in described on the support set 3, interior support set 3 and outside 4 of support sets be provided with a buckling and locking device.

Aforesaid buckling and locking device comprises upper end in-to-in bayonet lock 10, spring 12, endoporus jump ring 13, the spring shim 14 that is successively set on middle screw rod 9, be provided with draw-in groove 40 in the upper end of inner screw 11, bayonet lock 10 and draw-in groove 40 clampings, support set 4 upper ends are provided with groove 42 outside, and groove 42 locks circle 39 with jump ring and axle tightens mutually with jump ring 16.

When electronic jack is worked, inner screw 11 fully by in screw rod 9 be wrapped in interior hollow bulb, the upper end in-to-in bayonet lock 10 of middle screw rod 9, spring 12, endoporus jump ring 13, spring shim 14 are by the upper end of inner screw 11 chucking, and this moment, bayonet lock 10 snapped in the draw-in groove 40 of inner screw 11 upper ends; When 8 rotations of motor 5 driven gears, gear 8 is with inner screw 11 rotation because this moment bayonet lock 10 with draw-in groove 40 chuckings, inner screw 11 can not turn at middle screw rod hollow bulb, this moment inner screw 11 with middle screw rod 9 relative fixed, inner screw 11 with middle screw rod 9 also just along with big gear wheel 8 is rotated; Because of interior support set 3 inner hollow, and inwall is provided with the screw thread that matches with middle screw rod 9 appearance screw threads, be enclosed within the skin of interior support set 3 because of outer support set 4 (outer support set inner hollow and do not have screw thread), interior support set 3 is enclosed within middle screw rod 9 skins, inner screw 11 this moment support set 3 spirals in thereby middle screw rod 9 rotations impel rise, therefore the groove of outer support set 4 upper ends just in time locks circle 39 with casing 2 in-to-in jump rings and axle tightens mutually with jump ring 16 time, so can only being interior support set 3, this section process rises, when interior support set 3 rises to the height of setting, also just in time be that inner screw 11 is when separating with bayonet lock 10 this moment, because of gear 7 works on, just impel inner screw 11 to separate with middle screw rod 9, screw rod 9 rose during inner screw 11 continued to promote, flight 41 places of at this moment interior support set 15 are relative with outer support set 4 inner step layers block fixing, because of inner screw continues rotary work, thereby also just impel this moment outer support set 4 outer surface grooves and casing in-to-in axle to break away from jump ring 16, thereby make outer support set can do upward movement freely, thereby the utility model has reached support set 3 in the first lifting, promote the function of the stable operation of outer support set 4 again, also guaranteed the height that promotes.In addition, in order to reach higher top lifting height is arranged, the utility model has also increased the adjusting screw(rod) 38 of manual regulation height, adjusting screw(rod) 38 is arranged on the upper end of outer support set 4, the outside of adjusting screw(rod) 38 is provided with screw thread, the one end be connected a jacking block 37, the other end be arranged on the threads engaged of outer support set 4 ports, by the spinning in and out of adjusting screw(rod) 38, to guarantee to satisfy the requirement of higher jacking vehicle.

Casing 2 is provided with motor mount, one motor 5 is installed on the described motor mount, in its outer cover motor plastic jacket 43 is housed, be provided with illuminating lamp 44 in described motor plastic jacket 43 1 sides, can guarantee that the operator can normally use electronic jack under night or rather dark operating mode.As Fig. 3, this motor 5 comes to provide power for electronic jack work by the motor driven gear assembly.

In casing 2, also be provided with a circuit for controlling motor, one signal receiving unit is set in described circuit for controlling motor, described signal receiving unit receives the signal that the signal transmitter unit in the remote controller 6 sends, and signal is converted to circuit control signal, controls the running of described motor 5.Between the bottom of described base plate 1 and casing 2, be provided with one with bottom of shell shape, the suitable antivibration mat 7 of size, the mechanical stability in the time of can strengthening electronic jack work.

It should be noted that at last: above embodiment only in order to the explanation the utility model and and the described technical scheme of unrestricted the utility model; Therefore, although this specification sheets has been described in detail the utility model with reference to each above-mentioned embodiment,, those of ordinary skill in the art should be appreciated that still and can make amendment or be equal to replacement the utility model; And all do not break away from the technical scheme and the improvement thereof of spirit and scope of the present utility model, and it all should be encompassed in the claim scope of the present utility model.
