As Fig. 1 ~ 7, a kind of manual and electric dual-purpose scissor-like jack, comprises base 1 and supporting seat 2, and base 1 is fixed on push-and-pull dolly 23, jack can be made to enter into below the lower automobile in chassis by artificial push-and-pull, supporting seat 2 with by the equipment connection of jacking.
The scissors structure of scissor-like jack is made up of four arm, four arm are rotatably hingedly connected together the quadrangle being formed and have the first coercive mechanism 3, second coercive mechanism 4, the 3rd coercive mechanism 5 and the 4th coercive mechanism 6 four coercive mechanism mutually, apply to any one arm the shape that power can change quadrangle.Wherein, form the two-arm end winding support of the first coercive mechanism 3 on base 1, form the two-arm end winding support of the second coercive mechanism 4 on supporting seat 2, the two-arm forming the 3rd coercive mechanism 5 is provided with the first axle 8 passing perpendicularly through two-arm and two-arm is rotated around it, the two-arm forming the 4th coercive mechanism 6 is provided with the second axle 9 passing perpendicularly through two-arm and two-arm is rotated around it.
First axle 8 and the second axle 9 are provided through both screw mandrels 10, leading screw 10 connects with the first axle 8 screw thread is supporting, screw mandrel 10 end is through the second axle 9, and be pivotally fixed on the second axle 9, namely the relative position of screw mandrel 10 and the second axle 9 remains constant.Screw mandrel 10 rotates, and changes the distance between the first axle 8 and the second axle 9, thus changes the push-and-pull of transverse direction into vertical rising or decline.
Screw mandrel 10 is by electronic and manual two kinds of mode activated, and the device that wherein manual mode drives is free wrench 22, and free wrench 22 screw-casing is connected on screw mandrel 10 end, manually pulls spanner and screw mandrel is rotated, thus controls jack rising or decline.
Electric model drives leading screw 10 to rotate for using motor 11, and wherein the motor gear 14 of motor 11 is in transmission connection with the first gear 15 being arranged at screw mandrel 10 end, and leading screw 10 is driven by motor 11 and rotates, and promotes jack and rises or decline.
In order to ensure that electric and hand pattern does not interfere with each other, be therefore provided with shifter.Shifter is arranged at the drop-gear box 12 of the two-arm end being fixed on formation second coercive mechanism 4, drop-gear box 12 is provided with and passes perpendicularly through the S. A. 13 that can move up and down and can pivot (as shown in figs. 34, drawing be above-below direction up and down), S. A. 13 upper end is provided with spring 18, spring 18 is sheathed on S. A. 13, one end is fixed on S. A. 13, and the other end is fixed on the casing of drop-gear box 12.The lower end of S. A. 13 is provided with handle 3, moves S. A. 13 by drawing handle 3.
The axle that S. A. 13 is positioned at drop-gear box 12 is provided with two gears, be respectively the second gear 16 and the 3rd gear 17, the diameter of the second gear 16 is greater than the 3rd gear 17, wherein the second gear 16 and motor gear 14 are connected by meshing transmission, 3rd gear 17 and the first gear 15 are connected by meshing transmission, and motor 11 drives the second gear 16 and the 3rd gear 17 to drive the first gear 15 to rotate.
Pull down fixed handle 3 second gear 16 and motor gear 14 to be thrown off, the 3rd gear 17 and the first gear 15 are thrown off, and are switched to manual mode, avoid the interference of motor gear 14.
Fixed block 20 is provided with in drop-gear box 12, S. A. 13 is through fixed block 20, S. A. 13 is provided with radially protruding lock pin 19, fixed block 20 is provided with corresponding lock pin 19 by groove 21, by the through fixed block 20 of groove 21, fixed block 20 is also provided with by the vertical hold down groove 24 of groove 20, hold down groove 24 does not have through whole fixed block 20, just for fixing lock pin 19.
Lock pin 19 can slide up and down to be connected to by groove 21.In time being in electric model, lock pin 19 is the upper end of fixed block 20, spring 18 is in contraction state, when needing to be switched to manual mode, pull handle 3 that screw mandrel 10 is moved, be out of gear, lock pin 19 retracts to the lower end of fixed block 20, rotating S. A. 13 makes lock pin 19 be fastened in the hold down groove 24 of fixed block 20 bottom, and spring 18 is in tensile state.
During use, starter motor 11 drives the first gear 15 to drive leading screw 10 to rotate, and by positive counter regulation hand of rotation, leading screw 10 is advanced or retreat control jack decline or rise.
When the unexpected power-off of motor or other faults, because the annexation between screw mandrel 10 and the first axle 8 has latch functions, weight can not decline immediately, handle 3 can be pulled, gear is thrown off mutually, pulls free wrench 22, rotary screw 10 promotes jack and rises or decline.
The utility model, by by being manually integrated on scissor-like jack with electronic, can conveniently be applied to various vehicle, overcomes old-fashioned scissor-like jack and uses effort and the problem of inconvenience, and simple to operate, easy to install.
