This type of attachment claims to be bolted.As nut is screwed off from bolt, and the two parts can be made to separate, therefore be bolted
It is to belong to be detachably connected, because bolt is also one kind of railway casting, railway casting is the component part of rail track, as
One globality engineering structure, track laying play the guiding role of train operation on roadbed, directly receiving rolling stock
And its immense pressure of load.Under the power effect of train operation, its each component part must have enough intensity
And stability, bolt loosen, the bolt after loosening will not have fastening frequent occurrence under the alternate load effect that train passes through
Effect, influences whether traffic safety, needs periodically to patrol thus and be twisted again to guarantee bolt fastening at any time, makes railroad operator
Larger workload, and there are security risks.
Traditional non-return type check bolt can not prevent the loosening of bolt well, reduce strong when bolt is fixed
Degree and stability, greatly reduce the fixed effect of bolt, increase the labor intensity of staff, are not avoided that bolt pine
Dynamic risk bring security risk, increases the loss of user, the person of being not convenient to use carries out using not very practical.
Utility model content
In view of the deficiencies of the prior art, the utility model provides a kind of non-return type check bolt, and it is anti-to solve non-return type
Loose bolt can not prevent well bolt looseness and not be avoided that the problem of bolt looseness risk brings security risk.
In order to achieve the above object, the utility model is achieved by the following technical programs: a kind of non-return type check bolt,
Including bolt head, the bottom of the bolt head is fixedly connected with bolt column, and the surface of bolt column is arranged with anti-retaining backing plate,
Annulus tooth socket plate, the surface of the bolt column and the top for being located at annulus tooth socket plate are fixedly connected at the top of the anti-retaining backing plate
Portion is arranged with Circular Plate, and the bottom of Circular Plate is fixedly connected with annulus tooth block, and the inside of the bolt column offers card slot,
Through there is pin, one end that the pin extends to inside Circular Plate is through card slot and extends to card slot on the surface of the Circular Plate
Inner wall.
Preferably, the surface of the bolt column and be located at Circular Plate at the top of be arranged with elastomeric pad.
Preferably, partition is fixedly connected between the two sides of the card slot inner wall.
Preferably, the surface of the pin and the inner wall of card slot are fixedly connected with resilient material.
Preferably, the height of the annulus tooth socket plate is 1.5~2.5mm.
Beneficial effect
The utility model provides a kind of non-return type check bolt.Have compared with prior art following the utility model has the advantages that should
Non-return type check bolt is fixedly connected with bolt column by the bottom of bolt head, and the surface of bolt column is arranged with anti-retaining
Backing plate is fixedly connected with annulus tooth socket plate, the surface of bolt column and the top for being located at annulus tooth socket plate at the top of anti-retaining backing plate
It is arranged with Circular Plate, and the bottom of Circular Plate is fixedly connected with annulus tooth block, the inside of bolt column offers card slot, Circular Plate
Surface through there is a pin, one end that pin extends to inside Circular Plate is through card slot and extends to the inner wall of card slot, bolt column
Surface and be located at the top of Circular Plate and be arranged with elastomeric pad, can be good at the loosening for preventing bolt, it is solid to increase bolt
The strength and stability of timing greatly improves the fixed effect of bolt, reduces the labor intensity of staff, and avoids
Bolt looseness risk bring security risk, reduces the loss of user, carries out convenient for user using practical.
