Description

A kind of takeup type jack with screw rod hoister structure
Technical field
The utility model relates to a kind of jack, specifically a kind of takeup type jack with screw rod hoister structure.
Background technology
Jack is a kind ofly with rigidity top, to lift part as equipment, the light little weight-lifting equipment of jacking weight in stroke by top bracket or bottom claw.Jack is mainly used in the departments 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 when jack does not also touch weight, rise and fall slowly affect work efficiency very much.
Summary of the invention
The utility model is not enough for prior art, and a kind of takeup type jack with screw rod hoister structure is provided, and this takeup type jack can fast speed rise and fall when 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 utility model is solved by following technical proposals: a kind of takeup type jack with screw rod hoister structure, comprise base, on described base, be provided with screw rod hoister structure, in described screw rod hoister structure, be vertically provided with screw rod, described screw rod is through the first contiguous block, described the first contiguous block is rotatably connected to the first swivel arm and the second swivel arm, described the first swivel arm and the 3rd swivel arm are rotationally connected, described the second swivel arm and the 4th swivel arm are rotationally connected, described the 3rd swivel arm and described the 4th swivel arm are all rotationally connected with the second contiguous block, described screw rod 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 swivel arm 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.
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 finishing bevel gear cuter coordinating with described screw rod and the second finishing bevel gear cuter coordinating with the first finishing bevel gear cuter, on described the second finishing bevel gear cuter, 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 utility model compared with prior art, has following beneficial effect: this takeup type jack of the utility model can fast speed rise and fall when not touching weight, and after touching weight rising jack-up weight at a slow speed.
Accompanying drawing explanation
Fig. 1 is the integral structure schematic diagram of the utility model embodiment.
Fig. 2 is the structural representation that the utility model base connects the first crank.
Fig. 3 is that the A-A at ratchet place in Fig. 2 is to schematic diagram.
The specific embodiment
Below in conjunction with accompanying drawing and the specific embodiment, the utility model is described in further detail: referring to Fig. 1 to Fig. 3, a kind of takeup type jack with screw rod hoister structure, comprise base 1, on described base 1, be provided with screw rod hoister structure 110, the interior screw rod 2 that is vertically provided with of described screw rod hoister structure 110, described screw rod 2 is through the first contiguous block 3, described the first contiguous block 3 is rotatably connected to the first swivel arm 4 and the second swivel arm 5, described the first swivel arm 4 and the 3rd swivel arm 6 are rotationally connected, described the second swivel arm 5 and the 4th swivel arm 7 are rotationally connected, described the 3rd swivel arm 6 is all rotationally connected with the second contiguous block 8 with described the 4th swivel arm 7, described screw rod 2 upper ends are provided with the first fixed block 9, in described the first fixed block 9, be horizontally arranged with through hole (not shown on figure), 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 swivel arm 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 finishing bevel gear cuter 113 coordinating with described screw rod 2 and the second finishing bevel gear cuter 114 coordinating with the first finishing bevel gear cuter 113, on described the second finishing bevel gear cuter 114, be provided with the second crank 115.
Described ratchet 14 1 sides are provided with and lean piece 15.Therefore because the reversal interlocking relay of jack is very large, ratchet 14 can bear very large power, arranges to lean piece 15 ratchet 14 is withstood.
In described through hole, be provided with bearing.Bearing is set makes the first crank rotation lighter.
The jack of this structure in use, when touching weight, jack upper end do not rotate by rotating the first crank 10, make the second contiguous block 8 fast rise that the second contiguous block 8 is contacted with weight, cooperation first crank 10 of ratchet 13 ratchets 14 after touching weight, the second contiguous block 8 rotates jointly by weight jack-up by the first crank 10 and the second crank 115, owing to 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, when the first crank 10 slides into control 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, when the first crank 10 need to rotate backward, by again the first crank 10 being slided and can make ratchet 13 and ratchet 14 depart from after coping block 17.
