Abstract
The utility model discloses a hub anti-theft nut which comprises a nut sleeve and a thread stud. The nut sleeve is arranged outside the thread stud. Six planes are symmetrically arranged on the outer side of the nut sleeve. A through hole is formed in the center of the nut sleeve. Two half-cylinder protrusions are symmetrically arranged on the wall of the through hole. Two half-cylinder grooves are symmetrically formed in the external surface of the thread stud. The two half-cylinder protrusions are arranged in the two half-cylinder grooves respectively. Through the mode, a split structure is adopted for the hub anti-theft nut, when the nut is screwed, the nut sleeve is installed outside the thread stud, and the hub anti-theft nut can be screwed by a common internal hexagonal wrench. After tightening, the nut sleeve is taken out, the exterior of the left thread stud is smooth, so that the nut is difficult to detach by a common tool, the anti-theft performance is good, and the application range is wide.
Description
Technical field
The utility model relates to automobile profile anti-theft device field, particularly relates to a kind of wheel hub anti-theft nut.
Background technique
Nut is a kind of mechanical parts of commonly using, and it is used for playing the role of fastening together with bolt or screw rod are screwed in, and nut is full of in our life, has all applied a large amount of nuts or screw in computer, mobile phone, machinery and automobile.Because nut is fixing very convenient, dismantle also rapidlyer, therefore, in stolen article, because of nut, to be backed out the parts proportion of stealing smoothly quite high.
The nut using on automobile is many, the most significantly will calculate wheel position, and general wheel hub all needs 4 ~ 5 nuts to be fixed.Because nut is standard piece, the nut on wheel is easy to be laid down, so the stolen event of wheel hub is more frequent in recent years.Along with the development of auto technology, present automobile engine starting system is subject to vehicle-mounted computer control mostly, and common key is difficult to start, thus car thieves then target stare to wheel hub and the tire of wheel hub, particularly some high-grade cars.In order to increase the difficulty of wheel hub theft, part producer has adopted anti-theft nut to carry out the reinforcing of wheel hub, and the moulding difference of various anti-theft nuts, alleviate the stolen problem of wheel hub, but anti-theft nut all needs the special spanner of optional equipment, and cost is high, and carries inconvenience.
Model utility content
The technical problem that the utility model mainly solves is to provide a kind of wheel hub anti-theft nut, and Split type structure is easy to use, and theftproof performance is good, and cost is low.
For solving the problems of the technologies described above, the technological scheme that the utility model adopts is: a kind of wheel hub anti-theft nut is provided, comprise: nut sleeve and screw column, described nut sleeve is arranged on the outside of screw column, the outside of described nut sleeve is symmetrically arranged with six planes, the central position of described nut sleeve is provided with a through hole, on the hole wall of described through hole, be symmetrically arranged with two semicolumn projections, on the outer surface of described screw column, be symmetrically arranged with two semicolumn grooves, described two semicolumn projections are separately positioned in two semicolumn grooves, described two semicolumn grooves parallel with the central shaft of screw column respectively, the two ends of described semicolumn groove lay respectively at the two ends of screw column.
In preferred embodiment of the utility model, the central position of described screw column is provided with a tapped hole.
In preferred embodiment of the utility model, the outside of described screw column be one cylindrical, described columniform diameter is identical with the diameter of through hole.
In preferred embodiment of the utility model, the height of described nut sleeve is not less than the height of screw column.
In preferred embodiment of the utility model, described two semicolumn projections parallel with the central shaft of through hole respectively, and the two ends of described semicolumn projection lay respectively at the two ends of through hole.
The beneficial effects of the utility model are: a kind of wheel hub anti-theft nut that the utility model is pointed out, adopt Split type structure, and volume is small and exquisite, easy to carry, when screwing, nut sleeve is arranged on the outside of screw column, uses common inner hexagon spanner to screw, tighten and rear nut sleeve is taken out, the screw column outer smooth staying, is difficult to be dismantled by general purpose tool, and theftproof performance is good, with low cost, applied widely.
Brief description of the drawings
In order to be illustrated more clearly in the technological scheme in the utility model embodiment, below the accompanying drawing of required use during embodiment is described is briefly described, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing, wherein:
