Description
Technical field
The utility model belongs to chain technical field, especially relates to a kind of dislocation cranked link chain.
Background technique
Chain is generally chain link or the annulation of metal, and the multiplex mechanical transmission of doing can be divided into four kinds, Transmitted chains, Conveying chains, dragging chain and special chain by different purposes and function.Chain of the prior art is all often not have directively, can clockwise rotate around sprocket wheel, also can rotate counterclockwise, and there is no a kind of sprocket wheel can only individual event rotating; Between the inner plate of chain and outer plate, connect often firm not enough, easy de-chain.
For prior art is improved, people have carried out long-term exploration, have proposed various solutions.For example, Chinese patent literature discloses a kind of reinforced heavy-load bending plate chain [application number: CN201120273328.2], at least comprise the bent plate chain link of serial connection successively, in adjacent two bent plate chain links, the narrow end of a bent plate chain link is positioned at the wide end of another bent plate chain link, it is characterized in that: bent plate chain link comprises cranked plate, roller, sleeve and bearing pin, roller sleeve is on sleeve, bearing pin is installed on the wide end of bent plate chain link by pin shaft hole, sleeve is installed on the narrow end of bent plate chain link by sleeve hole, pin shaft hole is D shape hole, the cross section that is positioned at the position of pin shaft hole on bearing pin is D shape and matches with pin shaft hole., not only strengthened wear resistance and the tensile strength of whole chain, extended the working life of chain, make simultaneously whole chain at high pulling torque, have under the operating mode of impact, work more stable.
Although such scheme has solved the deficiencies in the prior art to a certain extent, has strengthened tensile strength, work more stable, still do not realize the function that chain can only one-way rotation around sprocket wheel.
Summary of the invention
The purpose of this utility model is for the problems referred to above, provides a kind of reasonable in design, simple in structure and dislocation cranked link chain that can only one-way rotation around sprocket wheel.
For achieving the above object, the utility model has adopted following technical proposal: this dislocation cranked link chain, comprise the chain link that cranked plate forms, described cranked plate comprises wide outer plate and narrow inner plate, described wide outer plate is connected by turn of bilge with narrow inner plate, between adjacent narrow inner plate, by bearing pin, be connected, described wide outer plate upper end is connected with connecting plate, described connecting plate and narrow inner plate are by the bearing pin chaining that joins each other, between a pair of wide outer plate, be provided with and be arranged in the one-way non-return structure of wide outer plate afterbody and at chain link sprocket wheel when wide outer plate circumferentially rotates to the direction of narrow inner plate, can rotate when sprocket wheel, when reverse, the sprocket on sprocket wheel is stopped and can not circumferentially rotate by unidirectional non-return structure.Wide in described wide outer plate means that the distance at carrier bar two ends is wider, distance between adjacent narrow inner plate is little compared with the distance of adjacent wide outer plate, when sprocket wheel is when wide outer plate circumferentially rotates to narrow inner plate direction, gear on described sprocket wheel leniently outer plate district moves to narrow inner plate district until be resisted against one-way non-return structure, now, gear driven chain rotates, when circumferentially rotating to narrow inner plate direction against wide outer plate, gear Cong Zhai inner plate district on described sprocket wheel moves to wide outer plate district, gear is pushed one-way non-return structure open and is entered into next chain link, can not drive the rotation of chain.
In above-mentioned dislocation cranked link chain, described one-way non-return structure comprises unidirectional baffle plate, described unidirectional baffle plate is connected with a pair of wide outer plate afterbody by coupling shaft, is provided with the block that stops that unidirectional baffle plate inwardly rotates between described wide outer plate and unidirectional baffle plate.When sprocket wheel is when wide outer plate circumferentially rotates to narrow inner plate direction, gear on described sprocket wheel leniently outer plate district moves to narrow inner plate district until be resisted against unidirectional baffle plate, because there is block to stop unidirectional baffle plate inwardly to rotate, so thereby gear can act on the rotation that unidirectional baffle plate drives chain; When circumferentially rotating to narrow inner plate direction against wide outer plate, gear Cong Zhai inner plate district on described sprocket wheel moves to wide outer plate district, when Gear Contact arrives unidirectional baffle plate, unidirectional baffle plate is not because there is no the stopping around moving on coupling shaft of block, gear enters into next chain link, can not drive the rotation of chain.
In above-mentioned dislocation cranked link chain, described connecting plate is integrated system or is connected by demountable structure with wide outer plate.One system is beneficial to firm connection the between connecting plate and wide outer plate, and demountable structure is beneficial to the dismounting and change of connecting plate.
In above-mentioned dislocation cranked link chain, between described connecting plate and narrow inner plate, be provided with reinforcement structure, described reinforcement structure comprises circular groove and the round bump adapting with circular groove.More firm by strengthening structure connection between described connecting plate and narrow inner plate, be difficult for the situation that chain disconnects occurs, extended working life.
In above-mentioned dislocation cranked link chain, described circular groove is on connecting plate, and described round bump is arranged on narrow inner plate.
As another kind of scheme, in above-mentioned dislocation cranked link chain, described round bump is on connecting plate, and described circular groove is arranged on narrow inner plate.
Compared with prior art, the advantage of this dislocation cranked link chain is: when sprocket wheel is when wide outer plate circumferentially rotates to narrow inner plate direction, gear on sprocket wheel leniently outer plate district moves to narrow inner plate district until be resisted against one-way non-return structure, gear driven chain rotates, when circumferentially rotating to narrow inner plate direction against wide outer plate, gear Cong Zhai inner plate district on sprocket wheel moves to wide outer plate district, gear is pushed one-way non-return structure open and is entered into next chain link, can not drive the rotation of chain; Simple in structure, stability is strong, detachable, and long service life is reasonable in design, practical.
