Specific embodiment
To be easy to understand the technical means, creative features, achievement of purpose, and effectiveness of the utility model, below
In conjunction with specific embodiment, the utility model is further described.
As shown in Figs. 1-2, a kind of anti-theft bolt, including nut 1, screw rod 2 and screw thread 6, the screw rod 2 are located under nut 1
End, the screw thread 6 are located at 2 surface of screw rod, and the nut 1 is arranged in cylindrical type, and 1 side wall of nut is smooth surface and spiral shell
Irregular shape jack 9 is embedded on 1 side wall of cap, the irregular shape jack 9 is equipped with two groups, and irregular shape jack 9
It is symmetrical set, protective ring 7 is arranged on the nut 1, the protective ring 7 is located at 9 outside of irregular shape jack.
(as shown in Figure 1) is by being in cylindrical type by the setting of nut 1 in the present embodiment, and 1 side wall of nut is arranged in smooth
Surface, it is possible to reduce the friction between common spanner and nut 1 is not easy to be dismantled, while being embedded in 1 side wall of nut
Irregular shape jack 9, so that bolt integrally needs specific tool to be rotatablely installed and dismantled, good anti-theft effect.
Wherein, protrusion is equipped with fixed block 8 on 1 two sidewalls of nut, and 8 upper end of fixed block is equipped with spring 10,
And 10 top of spring is connect with 7 bottom end of protective ring, the protective ring 7 is flexibly connected by spring 10 and fixed block 8 with nut 1.
It is (as depicted in figs. 1 and 2) in the present embodiment to be arranged by setting protective ring 7, and by protective ring 7 in irregular shape
9 outside of jack, can protect irregular shape jack 9, irregular shape jack 9 is prevented to be blocked, be easy to use.
Wherein, nut 3 is arranged on the screw rod 2,3 side of nut is equipped with gasket 4, and between gasket 4 and nut 3
