Abstract
The utility model provides a kind of small, dedicated anti-theft screw, comprise nut and screw rod, this screw surface has screw thread, cap body liner is provided with bottom nut, this cap body liner cross section is the circle in the cross section slightly larger than nut, this cap body liner is cylindrical shape thin slice, this nut is evenly provided with six curved wall grooves, this curved wall groove has arc-shaped smooth side wall, this nut top is provided with for being located and the top plane of alignment effect, this nut and cap body liner are formed in one, screw rod is also set with annular gasket, the upper surface of this annular gasket is provided with continuous print V-type skewed slot.The advantage that the utility model has and good effect are: the nut of redesign and annular gasket have stronger theftproof performance, if curved wall groove does not have special tool to be difficult to find and can be engaged and the method for rotating, if use external force rotation that cap body liner and annular gasket can be caused to kill by force, cause bolt to take out, thus greatly improve outdoor theftproof performance.
Description
Technical field
The utility model belongs to Special anti-theft fixed block technical field, especially relates to a kind of small, dedicated anti-theft screw.
Background technique
Screw is one of fastening workpiece that people are the most frequently used in working for a long time, usual screw is made up of rivet nut and head of a nail two-part, the head of a nail adopts plane structure, end face is provided with draw-in groove, and its anti-theft effect is poor, because the plane structure of existing top cap is convenient to the positive and negative rotation of screw-driver, thus take out or fix, particularly small-sized screw, ordinary people can easily use utility screwdriver to take out screw, cannot meet outdoor theft-proof requirement.
Summary of the invention
Problem to be solved in the utility model solves current screw anti-theft performance by force, and general anti-theft screw is bad in small-sized screw field applicability, is particularly suitable for small-sized open air or device-specific anti-theft screw.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of small, dedicated anti-theft screw, comprise nut and screw rod, this screw surface has screw thread, wherein, cap body liner is provided with bottom nut, this cap body liner cross section is the circle in the cross section slightly larger than nut, this cap body liner is cylindrical shape thin slice, this nut is evenly provided with six curved wall grooves, this curved wall groove has arc-shaped smooth side wall, this nut top is provided with for being located and the top plane of alignment effect, this nut and cap body liner are formed in one, screw rod is also set with annular gasket, the upper surface of this annular gasket is provided with continuous print V-type skewed slot.
This nut is evenly provided with six curved wall grooves, this curved wall groove has arc-shaped smooth side wall, could be rotated by means of only special tool, thus play antitheft effect, further, laminar cap body liner is provided with bottom nut, and continuous print V-type skewed slot is set at the upper surface of annular gasket, if use non-expert instrument forced rotating screw, the breakage of cap body liner can be caused to snap in V-type skewed slot, cause screw locked, be more difficult to open, play better anti-theft effect; The top plane on nut top is generally used for when multiple screw need coordinate neat for levelling used with alignment.
The upper surface of this annular gasket establishes spaced V-type skewed slot.
The upper surface of this annular gasket is provided with continuous print arcuation skewed slot.
The thickness of this cap body liner is 0.5-1mm.
This cap body liner is positioned at curved wall groove and is provided with cut-out paddle-tumble.
The object of V-type skewed slot coordinates with cap body liner, played locked effect at cap body liner during outside destroy, and therefore, V-type skewed slot is only a kind of typical technological scheme, and other settings playing identical object as U-shaped skewed slot etc. are consistent in fact with this programme.
The advantage that the utility model has and good effect are: the nut of redesign and annular gasket have stronger theftproof performance, if curved wall groove does not have special tool to be difficult to find and can be engaged and the method for rotating, if use external force rotation that cap body liner and annular gasket can be caused to kill by force, cause bolt to take out, thus greatly improve outdoor theftproof performance.

Embodiment
As shown in Figure 1-2, a kind of small, dedicated anti-theft screw, comprise nut 2 and screw rod 5, there is screw thread on this screw rod 5 surface, wherein, cap body liner 1 is provided with bottom this nut 2, this cap body liner 1 cross section is the circle in the cross section slightly larger than nut 2, this cap body liner 1 is cylindrical shape thin slice, this nut 2 is evenly provided with six curved wall grooves 3, this curved wall groove 3 has arc-shaped smooth side wall, this nut 2 top is provided with for being located and the top plane 4 of alignment effect, this nut 2 and cap body liner 1 are formed in one, screw rod 5 is also set with annular gasket 6, the upper surface of this annular gasket 6 is provided with continuous print V-type skewed slot 61.
The upper surface of this annular gasket 6 establishes spaced V-type skewed slot 61.
The upper surface of this annular gasket 6 is provided with continuous print arcuation skewed slot.
The thickness of this cap body liner 1 is 0.5-1mm.
This cap body liner 1 is positioned at curved wall groove 3 place and is provided with cut-out paddle-tumble.
Above embodiment of the present utility model has been described in detail, but described content being only preferred embodiment of the present utility model, can not being considered to for limiting practical range of the present invention.All equalizations done according to the utility model scope change and improve, and all should still belong within this patent covering scope.
