Abstract
The utility model discloses the bolt assemblies of adaptive fastening end face, including the bolt body of rod, the top of the bolt body of rod is equipped with the bolt head of outer-hexagonal or interior hexagonal, the outer circle of the bolt body of rod is arranged with gasket, it is characterized by: the gasket includes at least upper spherical pad and lower peripheral surface gasket, lower peripheral surface gasket is far from bolt head, upper spherical pad is close to bolt head, the upper surface of lower peripheral surface gasket is convex spherical, lower end surface is plane, the upper surface of upper spherical pad is plane, lower end surface is concave spherical surface, convex spherical, concave spherical surface spherical curvature having the same.The utility model can adaptive out-of-flatness fastening mounting plane, improve property easy for installation and connection reliability.
Description
Technical field
The utility model relates to a kind of fastener products, and in particular to a kind of bolt assembly.
Background technique
Bolt assembly is generally the sub-assembly of outer-hexagonal or hexagon socket head cap screw to related gasket, big in fastening mounting location
Amount is widely applied.But when being the inclined-plane of out-of-flatness for fastening mounting plane, need mounting hole vertical with inclined-plane holding, this
When just need the processing inclined on connected piece, and the processing of inclined hole is not easy to realize in a few thing occasion, especially wherein one
A connected piece is under the premise of processed straight thread hole.
Summary of the invention
In view of the deficiency of background technique, the technical problem to be solved by the utility model is to provide one kind can be adaptive uneven
Whole fastening mounting plane improves the bolt assembly of the adaptive fastening end face of property easy for installation and connection reliability.
For this purpose, the utility model adopts the following technical scheme that realize:
The bolt assembly of adaptive fastening end face, including the bolt body of rod, the top of the bolt body of rod are equipped with outer-hexagonal or interior six
The outer circle of the bolt head at angle, the bolt body of rod is arranged with gasket, it is characterised in that: the gasket includes at least upper spherical pad under
Spherical pad, lower peripheral surface gasket are convex ball close to bolt head, the upper surface of lower peripheral surface gasket far from bolt head, upper spherical pad
Face, lower end surface are plane, and the upper surface of upper spherical pad is plane, lower end surface is concave spherical surface, and convex spherical, concave spherical surface have identical
Spherical curvature.
The gasket further includes elastomeric pad, and elastomeric pad is set to the top of upper spherical pad.
The lower peripheral surface gasket has bigger diameter of bore compared to upper spherical pad.
The bolt assembly of above-mentioned technical proposal, can phase between the concave spherical surface of upper spherical pad and the convex spherical of lower peripheral surface gasket
To rotation, therefore after carrying out fastening installation to connected piece, no matter fasten mounting plane whether be out-of-flatness inclined-plane, lower ball
The lower end surface of face gasket can be flat and fit always with the fastening mounting plane of connected piece, and the upper surface of upper spherical pad can be with
The fastening end face of bolt head bottom is flat and fit, and so, connected piece is just not required to carry out the processing of inclined hole, effectively improves peace
Fill convenience and connection reliability.
Detailed description of the invention
The utility model has following attached drawing:
Fig. 1 is the structural schematic diagram of utility model.
Specific embodiment
As shown, the bolt assembly of the adaptive fastening end face of the utility model, including the bolt body of rod 5, the bolt body of rod 5
Top be equipped with the bolt head 1 of outer-hexagonal, the outer circle of the bolt body of rod 5 is arranged with gasket, the gasket include upper spherical pad 3,
Lower peripheral surface gasket 4 and elastomeric pad 2, lower peripheral surface gasket 4 is far from bolt head 1, and upper spherical pad 3 is close to bolt head 1, elastomeric pad
2 are set to the top of upper spherical pad 3, and the upper surface of lower peripheral surface gasket 4 is convex spherical 7, lower end surface is plane, upper spherical pad 3
Upper surface be plane, lower end surface is concave spherical surface 6, convex spherical 7, the spherical curvature having the same of concave spherical surface 6, the lower peripheral surface pad
Piece 4 has bigger diameter of bore compared to upper spherical pad 3, so that lower peripheral surface gasket 4 will not within the scope of rotation larger angle
Rotate interference between the outer circle of the bolt body of rod 5.
