Abstract
The invention discloses an anti-theft nut. The anti-theft nut comprises an upper end surface, a lower end surface, a lateral surface, a lower inclined hole, an upper inclined hole and a threaded hole, wherein the area of the upper end surface is smaller than that of the lower end surface, the lateral surface is an inclined surface connecting the upper end surface and the lower end surface, the lower inclined hole and the upper inclined hole are located in the two sides of the lateral surface respectively, the angle of the lower inclined hole is pointed at the lower end surface, the angle of the upper inclined hole is pointed at the upper end surface, and the threaded hole is a through hole connecting the upper end surface and the lower end surface. By means of the method, the anti-theft nut is simple in process, high in performance cost ratio, ingenious in design, good in anti-theft performance and suitable for various fixing situations needing safety and theft prevention, when matched with a spanner for use.
Description
Technical field
The present invention relates to the special type nut design field, particularly relate to a kind of anti-theft nut.
Background technique
Nut is a kind of mechanical parts of commonly using, its be used for playing the role of fastening together with bolt or screw rod are screwed in, the machinery of nearly all manufacturing all must be used nut.Nut of a great variety, the standard of every country is also different, and we common are GB, moral mark, English mark, American Standard and a day target nut.
Because nut is standard piece, exposed nut is easy to by artificial laying down, so the stolen event of wheel hub is of common occurrence.Particularly present vehicle cryptographic burglary protection system is very senior, is difficult to start, so car thieves transfer target is stared to very worthy wheel hub, the particularly wheel hub of some high-grade cars and truck and tire.Given this, a lot of auto vendors have adopted the nut with theftproof performance to fix wheel hub, have reduced the stolen possibility of car wheel hub.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of anti-theft nut, simple in structure, design is dexterous, theftproof performance is good.
For solving the problems of the technologies described above, the technological scheme that the present invention adopts is: a kind of anti-theft nut is provided, comprise: upper-end surface, lower end surface, side, lower inclined hole, upper inclined hole and tapped hole form, the area of described upper-end surface is less than the area of lower end surface, and described side is for connecting the inclined-plane of upper-end surface and lower end surface.Described lower inclined hole and upper inclined hole lay respectively at the both sides of side, and described declivity orifice angle is pointed to lower end surface, and described upper inclined hole angle is pointed to upper-end surface, and described tapped hole is for connecting the through hole of upper-end surface and lower end surface.
In a preferred embodiment of the present invention, there is chamfering at described tapped hole upper and lower port place.
In a preferred embodiment of the present invention, the opening of described upper inclined hole and lower inclined hole is at sustained height.
In a preferred embodiment of the present invention, the angle that described side and lower end surface form is 60 degree ~ 80 degree.
The invention has the beneficial effects as follows: a kind of anti-theft nut that the present invention points out, be different from general cylinder type anti-theft nut, adopted inclined-plane to add the design of asymmetric inclined hole, avoided the Point of Strength of common pliers and spanner, can coordinate its special spanner to use, simple in structure but theftproof performance good.
The accompanying drawing explanation
In order to be illustrated more clearly in the technological scheme in the embodiment of the present invention, in below describing embodiment, the accompanying drawing of required use is briefly described, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings, wherein:
Fig. 1 is the sectional drawing of anti-theft nut one preferred embodiment of the present invention;
Fig. 2 is the plan view of Fig. 1;
In accompanying drawing, the mark of each parts is as follows: 1, upper-end surface, 2, lower end surface, 3, side, 4, tapped hole, 5, lower inclined hole, 6, upper inclined hole.
Embodiment
Below will the technological scheme in the embodiment of the present invention be clearly and completely described, obviously, described embodiment is only a part of embodiment of the present invention, rather than whole embodiments.Embodiment based in the present invention, those of ordinary skills, not making all other embodiments that obtain under the creative work prerequisite, belong to the scope of protection of the invention.
Refer to Fig. 1 to Fig. 2, the embodiment of the present invention comprises:
A kind of anti-theft nut comprises: upper-end surface 1, lower end surface 2, side 3, lower inclined hole 5, upper inclined hole 6 and tapped hole 4 form, and the area of described upper-end surface 1 is less than the area of lower end surface 2, and described side 3 is for connecting the inclined-plane of upper-end surface 1 and lower end surface 2.Described lower inclined hole 5 and upper inclined hole 6 lay respectively at the both sides of side 3, and described lower inclined hole 5 angles are pointed to lower end surface, and described upper inclined hole 6 angles are pointed to upper-end surface, and described tapped hole 4 is for connecting the through hole of upper-end surface 1 and lower end surface 2.
The Details quality, in order to facilitate coordinating of anti-theft nut of the present invention and other bolts, tapped hole 4 upper and lower port places all are processed with chamfering.
General anti-theft nut is columniform, for fear of the violence of pressure clamp, tolls breakdown, and needs the attaching nut groove to use and just can have better anti-theft effect.And the anti-theft nut that the present invention points out, without the cooperation of groove, adopts the tapered slope design, side 3 is 60 degree ~ 80 degree with the angle that lower end surface 2 forms, and allows the pressure clamp end opening of having no way of, and theftproof performance is superior.
Anti-theft nut another one key point of the present invention is to have adopted two asymmetrical inclined holes as Point of Strength, although the opening of upper inclined hole 5 and lower inclined hole 6 is at sustained height, angle and position are not identical, and aperture is tiny, general purpose tool is difficult to put forth effort, and more can't rotate the nut fixed.
In sum, a kind of anti-theft nut that the present invention points out, technique is simple, and cost performance is high, but deft design, theftproof performance are good, coordinate special spanner to use, and are applicable to the fixing of various needs safe antithefts.
The foregoing is only embodiments of the invention; not thereby limit the scope of the claims of the present invention; every equivalent structure or conversion of equivalent flow process that utilizes description of the present invention to do; or directly or indirectly be used in other relevant technical field, all in like manner be included in scope of patent protection of the present invention.
