Bar annular array is provided with several cylinders, and the hexagon that the cylinder interior indent is provided on bolt end surface is recessed
Slot is provided with corresponding hexagon plug in the hexagonal indentations, and the bolt head other end indent, which is provided with, to be located at
Annular groove on the outside of screw rod, the annular groove inner wall are provided with the through-hole for extending to lateral surface, glue are provided in the annular groove
Water.
In one preferred embodiment of the utility model, the end of the cylinder is provided with chamfering.
In one preferred embodiment of the utility model, the hexagon plug is process for sticking plaster.
In one preferred embodiment of the utility model, the hexagon plug side is with hexagonal indentations inner wall gap
0.3~0.5mm。
In one preferred embodiment of the utility model, there are one convex for the hexagon plug side difference evagination setting
Platform.
In one preferred embodiment of the utility model, the bolt head side is provided with carburized layer.
The beneficial effects of the utility model are：A kind of bolt for facilitating loose unloading that the utility model is pointed out, when bolt rostral
When serious wear is pulled in face, bolt loose unloading does not come out, and can use allen wrench loose unloading bolt；When hexagonal indentations are worn
Afterwards, bolt loose unloading does not come out, and can carry out loose unloading bolt again from one bolt head of new welding on the cylinder, increase spiral shell
The loose unloading method of bolt and prolong the service life, glue fixes spring washer in annular groove, has anti-loosing effect.
Description of the drawings
It is required in being described below to embodiment in order to illustrate more clearly of the technical scheme in the embodiment of the utility model
Attached drawing to be used is briefly described, it should be apparent that, the accompanying drawings in the following description is only some realities of the utility model
