Open, therefore bolt connection is to belong to be detachably connected.Traditional bolt is smooth due to the through hole of screw rod and part, is made for a long time
After after slight loosen occurs between bolts and nuts, screw rod just has small acceleration spacing, forms momentum, and momentum switchs to punching
Amount, will produce it is larger pull power, make bolt continue to loosen, and then vicious circle, influence the fastening effect of bolt.Therefore,
A kind of excellent fastening bolt of fastening effect of demand.
Utility model content
In order to solve the above technical problems, the utility model provides a kind of fastening bolt, for deficiency of the prior art,
Using knockdown screw body, and the mode of the flange collar of vertical screw body axis is set, conventional bolt fastening is solved
The problem of effect is bad.
To reach above-mentioned purpose, the technical solution of the utility model is as follows：A kind of fastening bolt, including bolt head and combination
The screw body of formula；The bolt head is cylinder, and one end is provided with dismountable opening, and the other end is provided with screw hole, in
Between be cylinder accommodating cavity；Described screw body one end is provided with connector, and the connector coordinates with the accommodating cavity, card
In the accommodating cavity；The screw body other end is provided with the external screw thread of circumferential spiral surrounding；The screw body by
Two parallel axial planes are separated into positioned at the symmetrical arc screw rod of both sides and positioned at middle insertion screw rod；The arc spiral shell
The flange collar of a plurality of vertical screw body axis is axially arranged with the middle of bar；The arc screw rod is contacted with embedded screw rod
End face be respectively arranged with the location fin and detent of mutual cooperation.
As a kind of preferred scheme of the present utility model, the flange collar is 3-10 bars.
As a kind of preferred scheme of the present utility model, the bolt head sets the outer face of one end of screw hole to be provided with
Rubber blanket.
As a kind of preferred scheme of the present utility model, the screw body is made up of screw-thread steel.
As a kind of preferred scheme of the present utility model, the bolt head is made of stainless steel.
By above-mentioned technical proposal, the beneficial effect of technical solutions of the utility model is：The utility model is simple in construction to be closed
Reason, it is possible to prevente effectively from the loosening of axial direction occurs for bolt, so as to influence fastening effect, good with fastening effect, sound construction makes
With long lifespan, the good advantage of mechanical strength.
