Description
Technical field
The utility model relates to a kind of jack, specifically scissor-like jack.
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 scissor-like jack, and when jack does not also touch weight, rise and fall slowly affect work efficiency very much especially.
Summary of the invention
The utility model is not enough for prior art, and scissor-like jack is provided, and this scissor-like jack can fast speed rise and fall, improves the work efficiency of jack.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals: scissor-like jack, comprise 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 scissor-like jack also includes fixed block, on described fixed block, be provided with the first through hole, in described the first 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, article two, the other end of described cable wire removably connects with any described the first swivel arm and second swivel arm of both sides respectively, described at least one, on take-up pulley, be provided with ratchet, on described fixed block, be provided with ratchet, described ratchet and described click-fit.
In technique scheme, preferred, described ratchet one side is provided with and leans piece.
In technique scheme, preferred, in described the first through hole, be provided with bearing.
In technique scheme, preferably, on described the first swivel arm and described the second swivel arm, be provided with the second through hole, article two, described cable wire end is provided with bolt, and two described cable wires coordinate on the second through hole that is detachably connected on respectively described the first swivel arm and described the second swivel arm by bolts and nuts.
The utility model compared with prior art, has following beneficial effect: this scissor-like jack of the utility model can fast speed rise and fall, improves the work efficiency of jack.
Accompanying drawing explanation
Fig. 1 is the integral structure schematic diagram of the utility model embodiment.
Fig. 2 is the structural representation at the utility model the first crank place.
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, scissor-like jack, comprise the first contiguous block 1, described the first contiguous block 1 is rotatably connected to the first swivel arm 2 and the second swivel arm 3, described the first swivel arm 2 and the 3rd swivel arm 4 are rotationally connected, described the second swivel arm 3 and the 4th swivel arm 5 are rotationally connected, described the 3rd swivel arm 4 is all rotationally connected with the second contiguous block 6 with described the 4th swivel arm 5, described scissor-like jack also includes fixed block 7, on described fixed block 7, be provided with the first through hole, in described the first through hole, be equipped with the first crank 8, on described the first crank 8, be provided with two take-up pulleies 9, on two described take-up pulleies 9, be all fixed with cable wire 10, article two, the other end of described cable wire 10 removably connects with any described the first swivel arm 2 and second swivel arm 3 of both sides respectively, described at least one, on take-up pulley 9, be provided with ratchet 11, on described fixed block 7, be provided with ratchet 12, described ratchet 11 coordinates with described ratchet 12.
The reversal interlocking relay being subject to when the load-bearing due to ratchet 12 is very large, and therefore described ratchet 12 1 sides are provided with and lean piece 13.
More smooth for the first crank 8 is rotated, therefore in described the first through hole, be provided with bearing.
In the present embodiment, as a kind of concrete mode that removably connects, on described the first swivel arm 2 and described the second swivel arm 3, be provided with the second through hole, article two, described cable wire 10 ends are provided with 14, two described cable wires 10 of bolt and by bolt 14, coordinate with nut on the second through hole that is detachably connected on respectively described the first swivel arm 2 and described the second swivel arm 3.
The jack of this structure in use, rotating the first crank 8 rises the first contiguous block 1 to withstand up lifting of weight gradually, by making ratchet 11 and coordinating of ratchet 12 the first crank 8 can not rotate backward, when weight need to fall, bolt 14 is torn open and can make weight free fall, owing to being provided with ratchet 11 so the first crank 8, can only rotate to a direction, the cable wire that the mode of the dismounting by bolt 14 makes to move in take-up pulley 9 can lay out, adopt this structure just can not make ratchet 11 and ratchet 12 depart from and rotate backward so that the first crank 8 does not need to arrange slide construction, reduce the possibility that in working process, the first crank 8 slides jack is landed.
