Nail can wipe power using the increasing locked between holographic bolt enhancing tapping screw and carrier, effectively prevent loosening.
To achieve the above object, the invention proposes a kind of self tapping self-drilling screws that anti-loosening effect is good, including screw rod, spiral shell
Head, bone drill, several lockings holography bolt, the screw rod is cylindrical type, and the screw surface coiling protrusion is equipped with certainly
Tapping, the screw rod lower end are equipped with bone drill, and the bone drill is an integral molding structure with screw rod, the spiral shell
Bar upper end is equipped with screw head, is equipped with several thread cavities vertically in the screw head, and the thread cavity is opposite with screw rod to be arranged in parallel,
The locking holography bolt that can cooperate with thread cavity is equipped in the thread cavity, the locking holography bolt court divides into
It sets, the locking holography bolt is detachably connected with thread cavity.
Preferably, the screw head cross section is regular hexagon or regular quadrangle, the screw head outer ring is equipped with can be with
With the outer wall of bayonet spanner cooperation.
Preferably, the screw head is equipped with several anti-skidding latches towards screw rod end surfaces.
Preferably, the thread cavity at least there are two, the thread cavity is described around the equidistant branch in screw head center
The holographic bolt of locking is equipped in thread cavity.
Preferably, the thread cavity upper end be equipped with can be with thread cavity chamber lid engaged therewith, the thread cavity chamber
Lid is detachably clamped with thread cavity.
Preferably, the length of the holographic bolt of the locking is less than the thickness of screw head, the locking holography bolt top
End is equipped with allen wrench bayonet or Phillips screwdriver bayonet or straight screwdriver bayonet, the locking holography bolt lower end are set
There is top.
Preferably, the screw rod, screw head, bone drill are coaxially disposed, the screw rod, screw head, bone drill are
Integrated formed structure.
A kind of self tapping self-drilling screw that anti-loosening effect is good of the present invention the utility model has the advantages that the present invention by by self tapping from auger shell
Thread cavity is set in the screw head of nail and locks holographic bolt, after screw-driving, can be tightened, be locked by the way that holographic bolt will be locked
The top of tight holography bolt can withstand carrier surface, enhance frictional force, effectively prevent loosening.
Feature and advantage of the invention will be described in detail by embodiment combination attached drawing.
