Description
Technical field
The present invention relates to a kind of jack, specifically takeup type jack.
Background technology
Jack is a kind of with lifting part as equipment, the light little crane gear of jacking weight in stroke by top bracket or bottom claw in rigidity top. Jack is mainly used in the department such as factories and miness, communications and transportation as work such as Mechanical Help and other lifting, supports. Its structure is firm, flexibility and reliability lightly, and a people is portability and operation.
Generally in use, jack-up and the speed falling are quite slow for existing jack, and therefore in the time that jack does not also touch weight, rise and fall slowly affect operating efficiency very much.
Summary of the invention
The present invention is directed to prior art deficiency, takeup type jack is provided, this takeup type jack can rise and fall fast in the time not touching weight, and after touching weight rising jack-up weight at a slow speed.
In order to solve the problems of the technologies described above, the present invention is solved by following technical proposals: takeup type jack, comprise base, on described base, be provided with screw rod hoister structure, in described screw rod hoister structure, vertically there is screw rod, described screw rod is connected with the first contiguous block, described the first contiguous block is rotatably connected to the first cursor and the second cursor, described the first cursor and the 3rd cursor are rotationally connected, described the second cursor and the 4th cursor are rotationally connected, described the 3rd cursor and described the 4th cursor are all rotationally connected with the second contiguous block, on described base, be also provided with straight-bar, described straight-bar upper end is provided with the first fixed block, in described the first fixed block, be horizontally arranged with through hole, in described through hole, be equipped with the first crank, on described the first crank, be provided with two take-up pulleies, on two described take-up pulleies, be all fixed with cable wire, the other end of two described cable wires is fixedly connected with any described cursor of both sides respectively, described at least one, on take-up pulley, be provided with ratchet, on described the first fixed block, be provided with ratchet, described ratchet and described click-fit. the jack of this structure in use, in the time that not touching weight, jack upper end rotates by rotating the first crank, make the second contiguous block fast rise that the second contiguous block is contacted with weight, after touching weight, the second contiguous block rotates jointly by weight jack-up by screw rod hoister structure and the first crank, because cooperation first crank of click can not rotate backward.
In technique scheme, preferably, described screw rod hoister structure comprises the second fixed block, in described the second fixed block, be provided with cavity, in described cavity, be provided with the first bevel gear coordinating with described screw rod and the second bevel gear coordinating with the first bevel gear, on described the second bevel gear, be provided with the second crank.
In technique scheme, preferred, described ratchet one side is provided with and leans piece.
In technique scheme, preferred, in described through hole, be provided with bearing.
The present invention compared with prior art, has following beneficial effect: this takeup type jack of the present invention can rise and fall fast in the time not touching weight, and after touching weight rising jack-up weight at a slow speed.
Brief description of the drawings
Fig. 1 is the overall structure schematic diagram of the embodiment of the present invention.
Fig. 2 is the structural representation of embodiment of the present invention other direction.
Fig. 3 is that the A-A at ratchet place in Fig. 2 is to schematic diagram.
Detailed description of the invention
Below in conjunction with accompanying drawing and detailed description of the invention, the present invention is described in further detail: referring to Fig. 1 to Fig. 3, takeup type jack, comprise base 1, on described base 1, be provided with screw rod hoister structure 11, described screw rod hoister structure 110 is interior vertically screw rod 2, described screw rod 2 is connected with the first contiguous block 3, described the first contiguous block 3 is rotatably connected to the first cursor 4 and the second cursor 5, described the first cursor 4 and the 3rd cursor 6 are rotationally connected, described the second cursor 5 and the 4th cursor 7 are rotationally connected, described the 3rd cursor 6 is all rotationally connected with the second contiguous block 8 with described the 4th cursor 7, on described base 1, be also provided with straight-bar 120, described straight-bar 120 upper ends are provided with the first fixed block 9, in described the first fixed block 9, be horizontally arranged with through hole, in described through hole, be equipped with the first crank 10, on described the first crank 10, be provided with two take-up pulleies 11, on two described take-up pulleies 11, be all fixed with cable wire 12, the other end of two described cable wires 12 respectively with any described cursor 4 of both sides, 5, 6, 7 are fixedly connected with, described at least one, on take-up pulley 11, be provided with ratchet 13, on described the first fixed block 9, be provided with ratchet 14, described ratchet 13 coordinates with described ratchet 14.
Described screw rod hoister structure 110 comprises the second fixed block 111, in described the second fixed block 111, be provided with cavity 112, in described cavity 112, be provided with the first bevel gear 113 coordinating with described screw rod 2 and the second bevel gear 114 coordinating with the first bevel gear 113, on described the second bevel gear 114, be provided with the second crank 115. Described ratchet 14 1 sides are provided with and lean piece 15, because ratchet 13 is very large to the reversal interlocking relay of ratchet 14, therefore arrange and lean piece 15 ratchet 14 is withstood. In described through hole, be provided with bearing.
The jack of this structure in use, in the time that not touching weight, jack upper end rotates by rotating the first crank 10, the second contiguous block 8 fast rise are contacted with weight, rotation and the first crank 10 by the second crank 115 after the second contiguous block 8 touches weight rotate jointly by weight jack-up, because cooperation first crank 10 of ratchet 13 ratchets 14 can not rotate backward, after jack uses, first rotate the first contiguous block 3 until the second contiguous block 8 does not contact with weight, again the first crank 10 is slided ratchet 13 is no longer coordinated with ratchet 14 in through hole, such the first crank 10 just can rotate backward, in order to prevent that the first crank 10 in use from sliding, on described the first crank 10, be provided with groove 16, in described groove 16, be provided with the jacking block 17 being rotationally connected with the first crank 10, described jacking block 17 is connected by spring 18 with described groove 16, in the time that the first crank 10 slides into operating position, jacking block 17 ejects and withstands the first fixed block 9, prevent that the first crank 10 slips from causing weight to fall accidents caused, in the time that the first crank 10 need to rotate backward, can make ratchet 13 and ratchet 14 depart from by again the first crank 10 being slided after coping block 17.
