Model utility content
The deficiency existing for prior art, the utility model provides a kind of American Standard hex head bolt, and this American Standard hex head bolt can not only play fixation, also has good sealability.
For achieving the above object, the utility model provides following technological scheme: a kind of American Standard hex head bolt, comprise the bolt head that is hexagon being wholely set successively, back-up ring and the cylindrical bolt shank of pie, bolt shank is provided with outside thread, the external diameter of back-up ring is greater than the external diameter of bolt shank, the end face of corresponding bolt shank one side of back-up ring is provided with the annular groove around bolt shank, is provided with seal ring in annular groove.
By adopting technique scheme, the end face of corresponding bolt shank one side of back-up ring is provided with the annular groove around bolt shank, in annular groove, be provided with seal ring, after this bolt is fixedly connected with object, the end face of corresponding bolt shank one side of back-up ring and object laminating, now the seal ring in annular groove is fitted with object contact face simultaneously, makes this bolt can not only play the effect being fixedly connected with, also there is good sealability, can be applicable to some sealability is required to strict occasion.
The utility model is further set to, and the other end end face of the corresponding bolt shank of described bolt head is provided with interior hexagonal groove.
By adopting technique scheme, bolt head is hexagon, can use common wrench this bolt to be tightened or the operation of loose unloading; The other end end face of the corresponding bolt shank of bolt head is provided with interior hexagonal groove, when there is no common wrench, also can use the inner hexagon spanner of adaptive this interior hexagonal groove to pull this bolt, makes this bolt can adaptive multiple types of tools, and applicability is strong.
The utility model is further set to, and described bolt head is provided with friction part.
By adopting technique scheme, bolt head is provided with friction part, strengthens the friction factor of this bolt head, and convenient wrench is tightened this bolt or loose unloading operation.
The utility model is further set to, and the termination of the corresponding bolt head the other end of described bolt shank is provided with chamfering.
By adopting technique scheme, the termination of the corresponding bolt head the other end of bolt shank is provided with chamfering, and when this bolt is installed, chamfering facilitates bolt shank to aim at mounting hole, makes installation more convenient accurately.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model American Standard hex head bolt;
Fig. 2 is the structural representation of the utility model bolt head.
Reference character: 1, bolt head; 11, interior hexagonal groove; 2, back-up ring; 21, annular groove; 22, seal ring; 3, bolt shank; 4, chamfering.
Embodiment
Referring to figs. 1 through Fig. 2, the utility model American Standard hex head bolt embodiment is described further.
A kind of American Standard hex head bolt, comprise the bolt head that is hexagon 1 being wholely set successively, back-up ring 2 and the cylindrical bolt shank 3 of pie, bolt shank 3 is provided with outside thread, the external diameter of back-up ring 2 is greater than the external diameter of bolt shank 3, the end face of corresponding bolt shank 3 one sides of back-up ring 2 is provided with the annular groove 21 around bolt shank 3, is provided with seal ring 22 in annular groove 21.
