Description
Technical field
The utility model is related to the chain that a kind of coarse pitch prevents bearing pin from rotating, and belongs to chain technical field.
Background technology
In the prior art, the general all routines of fastener that chain joint is used select Clip Reed, and Clip Reed is by spring steel
Thin slice quenching is formed, and feature is easy processing, easy to assembly, but also easy to fall off, therefore there is hidden danger, Clip Reed also relation
It is the part of one considerable " unremarkable " to the reliability service of whole chain, but existing Clip Reed was being used
Cheng Zhong, due to being used cooperatively with bearing pin, the jump-ring slot on bearing pin is circular, in use, bearing pin easily spins, cause bearing pin with
Pivoting friction between outer plate, the time one is grown, and easily causes outer plate failure, influences the service life of chain.
Utility model content
The utility model purpose is to overcome the deficiencies in the prior art and fine motion friction can be reduced, prevents by providing one kind
The coarse pitch that bearing pin is rotated prevents the chain that bearing pin is rotated.
To reach above-mentioned purpose, the technical solution adopted in the utility model is：A kind of coarse pitch prevents the chain that bearing pin is rotated
Bar, including outer plate, inner plate, only roller, lock pad and bearing pin；Roller is provided between the outer plate and inner plate and is passed through
Bearing pin is connected；The outer plate is provided at both ends with axis hole；Two have also been horizontally spaced about between the axis hole of the outer plate two ends
Individual fixing hole；The only lock pad is in strip；One end of the only lock pad is provided with bolt hole, and the other end is provided with logical
Hole；Strip grooves are provided with the outside of the through hole；The through hole is connected with strip grooves and set；One end of the bearing pin is provided with convex
Platform, the other end is arranged with rectangular recess；The strip grooves of the only lock pad are fastened in the corresponding rectangular recess of bearing pin；It is described
Only the bolt hole of lock pad is connected by screw bolt and nut with the fixing hole of corresponding outer plate.
It is preferred that, it is additionally provided with spring washer between the bolts and nuts.
It is preferred that, it is additionally provided with sleeve between the bearing pin and inner plate.
Due to the utilization of above-mentioned technical proposal, the utility model has following advantages compared with prior art：
Coarse pitch described in the utility model prevents the chain that bearing pin is rotated from, by setting rectangular recess in bearing pin one end, making
Only the strip grooves of lock pad are fastened in rectangular recess, while fixing hole and corresponding only lock pad of the bolt through outer plate
Bolt hole is simultaneously fixed both by nut, is so avoided the fine motion friction between bearing pin and the axis hole of outer plate, can be prolonged
The service life of long outer plate.

Embodiment
Below in conjunction with the accompanying drawings and specific embodiment the utility model is described in further detail.
Accompanying drawing 1-3 is that coarse pitch described in the utility model prevents the chain of bearing pin rotation, including outer plate 1, inner plate
2nd, roller 3, only lock pad 4 and bearing pin 5；Roller 3 is provided between the outer plate 1 and inner plate 2 and is connected by bearing pin 5；Institute
That states outer plate 1 is provided at both ends with axis hole 6；Two fixing holes have also been horizontally spaced about between the two ends axis hole 6 of outer plate 1
7；The only lock pad 4 is in strip；One end of the only lock pad 4 is provided with bolt hole 9, and the other end is provided with through hole 8；Institute
The side for stating through hole 8 is provided with strip grooves 10；The strip grooves 10 form an opening in the end of only lock pad 4；It is described logical
Hole 8 is connected with strip grooves 10 and set；One end of the bearing pin 5 is provided with boss 11, and the other end is arranged with rectangular recess 12；Institute
The strip grooves 10 for stating only lock pad 4 are fastened in the corresponding rectangular recess 12 of bearing pin 5；The bolt hole 9 of the only lock pad 4 passes through
Bolt 13 and nut 14 are connected with the fixing hole 7 of corresponding outer plate 1；Spring pad is additionally provided between the bolt 13 and nut 14
Circle 15；Sleeve 16 is additionally provided between the bearing pin 5 and inner plate 2.
Coarse pitch described in the utility model prevents the chain that bearing pin is rotated by setting rectangular recess in the one end of bearing pin 5
12, the strip grooves 10 for only locking pad 4 is fastened in rectangular recess 12, while bolt 13 through outer plate 1 fixing hole 7 with it is right
The bolt hole 9 for the only lock pad 4 answered simultaneously is fixed both by nut 14, so avoids the axis hole 6 of bearing pin 5 and outer plate
Between fine motion friction, the service life of outer plate 1 can be extended.
It the above is only concrete application example of the present utility model, any limit do not constituted to protection domain of the present utility model
System.Technical scheme formed by all use equivalent transformation or equivalent replacements, all fall within the utility model rights protection scope it
It is interior.
