Abstract
A special kind of theftproof nut screw is provided, which comprises a screw cap body (1). The utility model is characterized in that: the outside of the screw cap body is in a circle shape, and the screw cap body (1) is externally provided with irregular sockets (2) in irregular shapes and asymmetric arrangement. The structure of the irregular sockets includes: V shape, W shape, F shape, P shape, zigzag shape and sunken shape. The structure of a sleeve applied together with the safe-guard nut screw is as bellow: the internal face of the sleeve is provided with a heteromorphy socket which has a yin and yang cooperation with the heteromorphy socket out of the screw cap body. The utility model has the advantages of tightness and firmness as the utility model is provided with a special tool. Furthermore, the safe-guard nut screw cannot be disassembled by the common tools, but easily disassembled by the special sleeve. As well, the utility model has a simple structure and works reliably.
Description
Technical field
The utility model belongs to engineering element or component technology field, particularly a kind of device of using with fastening or fixed component or machine parts of using.
Background technique
Nut and screw rod are the most frequently used fastening means of mechanical field, and as standard piece, the nut on nut and the screw rod is outer hexagonal shaped formula, though satisfied the common wrench requirement of installation and removal easily.But need prevent the special occasions dismantled privately at some, the defective of this nut and screw rod just clearly causes fastened object to be lost through regular meeting.Such as tightening automobile storage battery, license plate etc. at automobile, and the iron tower of power supply circuit, the protective gratings of expressway etc. use plain nut and screw rod fastening, and stolen robber person steals these objects or iron tower is dismounted badly with common wrench through regular meeting.
Be head it off, have the technological scheme of a lot of anti-theft nuts and screw rod to be suggested.Typical structure mainly comprises two kinds, the one, on nut or screw rod, have pinhole, the wedging pin destroys threaded line and prevents to dismantle privately in the hole, another basic structure be nut that an outside is the conical surface be inserted in have internal taper hole six side's swivel nuts in, rely on conical surface combination.The former has destroyed the structure of nut and screw rod, has reduced mechanical strength; The latter then owing to throw off too early between tapered sleeve and the nut cause fastening firm inadequately.
Summary of the invention
The utility model purpose is a kind of extraordinary anti-theft nut screw rod of design, to overcome the defective of existing anti-theft nut and screw rod.
Specifically, a kind of extraordinary anti-theft nut screw rod has nut body (1), it is characterized in that nut body (1) is outside rounded, and is shaped on out-of-shape on nut body (1) outer side surface, arranges asymmetric profiled slot (2).
Described profiled slot structure comprises: V-arrangement, W shape, F shape, P shape, huge font, concave shape.
The sleeve that a kind of and above-mentioned extraordinary anti-theft nut screw rod is used, its structure are that sleeve interior surface is shaped on the special-shaped groove that cooperates with the outer special-shaped groove negative and positive of nut body.
A kind of extraordinary anti-theft nut screw rod has nut body (1), and it is rounded in the nut body outside, and is shaped on blind hole at the one end, is shaped on out-of-shape on this blind hole internal surface, arranges asymmetric profiled slot (2).
The sleeve that a kind of and above-mentioned extraordinary anti-theft nut screw rod is used, its sleeve outer surface are shaped on the special-shaped projection that cooperates with special-shaped groove negative and positive on the nut body blind hole internal surface.
The utility model advantage is to be used with special tool, and is not only fastening firm, and uses general purpose tool to dismantle, and needs dismounting to use the socket wrench specially adapted for it dismounting easily.Overall structure is simple, reliable operation.
Description of drawings
Accompanying drawing is the utility model structural representation.
Embodiment
Provided the utility model embodiment as shown in drawings.Profiled slot structure described in the utility model comprises: various forms such as V-arrangement, W shape, F shape, P shape, huge font, concave shape but the form that is not limited only to enumerate.The special-shaped groove of different shape is arranged can not be symmetrical, inconsistent as at least 7 and 1,8 and 2,9 and 3,10 and 4,11 and 5,12 and 6 these groove shapes that are in symmetrical position among the figure.
A kind of extraordinary anti-theft nut screw rod has nut body (1), it is characterized in that nut body (1) is outside rounded, and is shaped on out-of-shape on nut body (1) outer side surface, arranges asymmetric profiled slot (2).In order to prevent to adopt the dismounting of pipe wrench one class instrument, can add one deck wrist shape sheath at nut body.
The sleeve that a kind of and above-mentioned extraordinary anti-theft nut screw rod is used, its structure are that sleeve interior surface is shaped on the special-shaped groove that cooperates with the outer special-shaped groove negative and positive of nut body.
For a door nut commonly used, its structure can also be a kind of extraordinary anti-theft nut screw rod, has nut body (1), and it is rounded in the nut body outside, and be shaped on blind hole at the one end, on this blind hole internal surface, be shaped on out-of-shape, arrange asymmetric profiled slot (2).
The sleeve that a kind of and above-mentioned extraordinary anti-theft nut screw rod is used, its sleeve outer surface are shaped on the special-shaped projection that cooperates with special-shaped groove negative and positive on the nut body blind hole internal surface.
Claims (6)
