Description
Technical field
The utility model relates to part technical field, particularly relates to a kind of anti-theft screw.
Background technique
As everyone knows, in the prior art, screw is made up of screw cap, screw rod and screw head, the integral setting of screw cap, screw head and screw rod, uses and is often used for fixing two links, uses and also facilitates.If connected piece is in outdoor, and time more valuable, be easy to stolen.In order to reduce connected piece, stolen possibility occurs, we have developed a kind of anti-theft screw that can be antitheft.
Model utility content
In order to solve the problems of the technologies described above, the utility model provides a kind of reasonable in design, not easily stolen anti-theft screw, comprise screw cap, screw rod and screw head, described screw cap is made up of screw cap A and screw cap B, the bottom of described screw cap A offers a groove A, described screw cap B upper surface is provided with the projection A of a cylinder type, described projection A and groove A is that movable the twisting of screw thread connects, be connected with screw rod below described screw cap B, described screw rod is made up of screw rod A and screw rod B, described screw rod A lower surface offers a groove B, described screw rod B upper surface is provided with the projection B of a cylinder type, described projection B and groove B is that movable the twisting of screw thread connects, screw head is provided with below described screw rod B, a packing ring is provided with below described screw cap B, described packing ring is placed on screw rod A, described screw cap A surface is provided with cell body.
Described projection A and the screw thread of groove A are twisted and are twisted to identical to the screw thread of projection B and groove B.
Described screw cap A is identical with the diameter of screw cap B.
Described screw rod A is identical with the diameter of screw rod B.
Described screw rod surface is provided with screw thread.
Described cell body is straight groove body or cross cell body.
The beneficial effects of the utility model are: the design of packing ring, it is made not easily to loosen, it is more permanent to use, screw rod A lower surface offers a groove B, screw rod B upper surface is provided with the projection B of a cylinder type, projection B and groove B is that movable the twisting of screw thread connects, make thief in theft process, twist the cell body on screw cap A, screw cap A can only be backed out, screw cap B cannot be backed out, screw cap B upper surface is provided with the projection A of a cylinder type, this projection A is very short, cannot well clamp, thus ensure that the safety of screw, even if screw cap B and screw rod A is backed out by instruments such as pliers, screw rod B and screw head are still followed closely in object, thus after making thief only steal a screw, will abandon stealing, the utility model structure is simple, reasonable in design.
