Increase the frictional force of the screw thread on bolt by the elastic force of spring washer, but this fastening means are likely to occur bolt
The phenomenon of abjection screwed hole, it is impossible to be enough prevented effectively from the loosening of bolt, therefore propose a kind of bolt of connection fastening.
【Utility model content】
The purpose of this utility model is exactly to solve the problems of the prior art, it is proposed that a kind of bolt of connection fastening, profit
With the cooperation of slide bar and spring, the screw thread and connector on bolt can be increased in certain active force that is axially formed of bolt
Between frictional force, and by agnail piece clamping screw, make bolt connection more firm.
For achieving the above object, the utility model proposes a kind of connect the bolt for fastening, including bolt head, screw rod, cunning
Bar, spring and adapter sleeve, are connected with screw rod below the bolt head, the screw rod is cylinder, and the periphery of the screw rod sets
The inside for having screw thread, the screw rod is provided with installation cavity, and the installation intracavity is provided with spring, and the spring is connected with slide bar, institute
The lower end for stating slide bar is provided with adapter sleeve, and the adapter sleeve is provided with several agnail pieces, and the lower end of the screw rod is provided with taper
Face, the taper surface is engaged with agnail piece.
Preferably, the cross sectional shape of the slide bar is circle, the cross sectional shape of the installation cavity is circle, the slide bar
Coincide with the axis of installation cavity, the diameter of the slide bar is less than the diameter of installation cavity.
Preferably, the top of the installation cavity is provided with installation fixture block, annular slot is offered on the installation fixture block, institute
State spring to be inlaid in annular slot.
Preferably, the bolt head is hexagonal prism, the inner groove of hexagon is provided with the bolt head, it is described interior heavy
Cross deep gouge is provided with groove, two rectangular slots are offered on the side wall of the bolt head.
Preferably, outer diameter length of the outer diameter length of the adapter sleeve less than screw rod.
The beneficial effects of the utility model：This utility model is by bolt head, screw rod, slide bar, spring and adapter sleeve etc.
Coordinate, using the cooperation of slide bar and spring, can in certain active force that is axially formed of bolt, increase screw thread on bolt with
Frictional force between connector, and coordinated by taper surface and adapter sleeve, agnail piece radial dilatation clamping screw connects bolt
Connect more firm.
Feature of the present utility model and advantage will combine accompanying drawing and be described in detail by embodiment.
