Description
Technical field
The utility model belongs to technical field of operation, relates to a kind of hand-operated tools, particularly a kind of chain strainer.
Background technology
In freight transportation process, traditional goods adopts rope stretch binding, also exist labour intensity large, bundle the problems such as insecure.There has been proposed ribbon strainer for this reason, have easy to operate and bundle firmly advantage, but there is the demand that pulling force that ribbon can carry cannot meet fixing large-sized object.The pulling force that chain can carry is larger, and thus those skilled in the art wish chain to be applied in strainer.
Summary of the invention
The utility model proposes a kind of chain strainer, the technical problems to be solved in the utility model how to propose a kind of chain strainer.
The technical problem that will solve of the present utility model realizes by following technical proposal: a kind of chain strainer comprises box body, chain, chain turning wheel and spanner, the axle core of chain turning wheel goes out to be equipped with a rotating shaft, rotating shaft is also through an end of spanner, rotating shaft is fixed on box body, and chain turning wheel is positioned at box body; Chain turning wheel is fixed with ratchet, and spanner is provided with the ratchet forming check configuration with ratchet; It is characterized in that, be also fixed with chain fairlead in described box body to have two chain pilot holes in chain fairlead, chain turning wheel walked around by chain and the two ends of chain are passed from two chain pilot holes respectively.
This strainer adopts chain carrying pulling force, and thus this chain strainer can carry larger pulling force compared with existing ribbon strainer.
Chain in this chain strainer is under the guiding of chain fairlead, both effectively and stably ensure that length of action between chain and chain turning wheel, chain state can be arranged again, ensure the chain link embedded groove state consistency of chain state and chain turning wheel, thus to considerably improve between chain with chain turning wheel snap-in force and be engaged stability, in other words, chain not easily slides, and chain more easily snaps in the chain link embedded groove of chain turning wheel.

Detailed description of the invention
Be below specific embodiment of the utility model and by reference to the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiments.
As shown in Figure 1, this chain strainer comprises box body 1, chain 2, chain turning wheel 3 and spanner 4, and the axle core of chain turning wheel 3 goes out to be equipped with a rotating shaft 5, and rotating shaft 5 is also through an end of spanner 4, rotating shaft 5 is fixed on box body 1, and chain turning wheel 3 is positioned at box body 1; Chain turning wheel 3 is fixed with ratchet 6, spanner 4 is provided with the ratchet 7 forming check configuration with ratchet 6, and chain turning wheel 3 walked around by chain 2.As shown in Figure 1, pull 90 ° from position shown in heavy line spanner 4 and arrive position shown in fine line spanner 4, ratchet 7 drives ratchet 6 to rotate; Pull 90 ° from position shown in fine line spanner 4 and arrive position shown in heavy line spanner 4, ratchet 7 departs from ratchet 6, and namely ratchet 6 can not drive ratchet 6 to rotate.
As shown in Figures 2 and 3, the wheel face of chain turning wheel 3 has four circumferences to be uniformly distributed horizontal chain link embedded groove 3a and four circumference and to be uniformly distributed vertical chain link embedded groove 3b, the docking end to end of adjacent transverse chain link embedded groove 3a, four vertical chain link embedded groove 3b are distributed in four horizontal chain link embedded groove 3a joint end to end correspondingly.
Horizontal chain link embedded groove 3a is flatter, and in Fig. 1, horizontally disposed chain link A can just embed in horizontal chain link embedded groove 3a.Vertical chain link embedded groove 3b is vertically arranged relative to horizontal chain link embedded groove 3a, and the central cross-section of vertical chain link embedded groove 3b and the central cross-section of horizontal chain link embedded groove 3a are same plane, and be symmetrical structure, this structure and chain 2 are tightened rear state and be consistent.The notch place of horizontal chain link embedded groove 3a and vertical chain link embedded groove 3b all has importing inclined-plane 3c, and then in the horizontal chain link embedded groove 3a making chain 2 more easily embed chain turning wheel 3 and vertical chain link embedded groove 3b.
As shown in Figure 4 and Figure 5, ratchet 7 and spanner 4 are rotationally connected, and ratchet 7 are fixed with poke rod 7a, ratchet 7 can be made to be meshed with ratchet 6 or be separated by operation poke rod 7a.When spanner 4 is pulled to driving direction of rotation, spanner 4 leans with the end of poke rod 7a, forces ratchet 7 to swing and is meshed with ratchet 6, ensures the action needed for realizing.Being provided with the first spring 8, first spring 8 between spanner 4 and ratchet 7 makes ratchet 7 and ratchet 6 have separation trend all the time, and in other words, when spanner 4 is oppositely pulled, ratchet 7 is just separated automatically with ratchet 6.In order to ensure chain turning wheel 3 to be made still to remain static after ratchet 6 is separated with ratchet 7, in box body 1, be so also provided with the pawl 9 be meshed with ratchet 6, pawl 9 and box body 1 are rotationally connected, and be provided with pawl 9 and ratchet 6 can be made to have the second spring engaging and drive all the time between pawl 9 with box body 1.
As shown in Figure 4 and Figure 5, chain fairlead 10 is also fixed with in box body 1, chain 2 is under the guiding of chain fairlead 10, to considerably improve between chain 2 with chain turning wheel 3 snap-in force and be engaged stability, in other words, chain 2 not easily slides, and chain 2 more easily snaps in the chain link embedded groove of chain turning wheel 3.Specifically, chain fairlead 10 comprises the block set 10a be fixedly connected with the box body 1 and two pieces of arc backplate 10b be fixedly connected with block set 10a, and two pieces of arc backplate 10b lay respectively at chain turning wheel 3 the upper side and lower side.Block set 10a has two chain pilot hole 10c, chain pilot hole 10c is cross bore, and obviously, chain 2 passes from chain pilot hole 10c.
