Embodiment
The utility model embodiment is described further below in conjunction with the accompanying drawings.
As depicted in figs. 1 and 2, a kind of self-locking screw for equidistant part, including nut 1, the and of integrally formed screw rod 2
Screw head 3, described screw rod 2 forms by component end 4, the end of thread 5 and from lock end 6, described to be radially provided with from lock end 6 through self-locking
The through hole 7 at end 6, described through hole 7 is interior to be provided with elastic component 8, and elastic component 8 herein can be helical spring, described elastic component 8
Both ends are connected with connecting rod 9, and the described both ends of connecting rod 9 are provided with self-locking block 10, and the described side of screw head 3 is excessive using circular arc
11, the end face of the screw head 3 is provided with groove 12, and regular hexagon boss 13, existing screw head 3 one are provided with described groove 12
As the bare terminal end that screws and screw out as bolt using hexagonal structure, this facilitate that being also convenient for while bolt disassembly illegal
The pilferage of molecule, and the side of screw head of the present utility model 3 is excessive using circular arc, eliminates bare terminal end, but set in screw head 3
As bare terminal end, in the case where wood has kit, bolt will be difficult to screw out regular hexagon boss, serve antitheft well
Effect.
Preferably, described self-locking block 10 is that side has the spherical of plane, and towards the end of thread 5, this is tied described plane
Structure is easy to be inserted in nut 1 when installation, and nut 1 is inserted in subordinate's pressure self-locking block 10 without special, and is locked in nut 1
After lock assembly, the plane and nut 1 on self-locking block 10 are inconsistent, have more preferable stuck restriction effect, avoid nut 1 from existing
Voluntarily produced in the environment and equipment of shake.
