Abstract
The utility model relates to an antitheft fastener, in particular to an antitheft nut with a sawtooth structure. When an existing antitheft nut is used for fastening a part or component outdoors, since the existing antitheft nut is of a structure of independently mounting a steel column or steel ball in a groove, the structure can be detached by others if a large-sized wrench is used for enabling wrenching force to be larger than certain torque, and consequently items are stolen. The antitheft nut of the sawtooth structure is characterized in that a nut body is an internally-threaded nut, an arc-shaped inclined groove is reserved on the inner wall of the nut, a steel ball is arranged in the inclined groove, convex strips are arranged on the outer wall of the nut body, and a sleeve matched with the nut body is sleeved on the outer wall of the nut body and is in close fit with the convex strips. The antitheft fastener is of a double-part structure of the nut body and the sleeve, when force reaches a certain degree, the sleeve can rotate around the nut body, so that the nut body cannot be unscrewed, and further double antitheft effect is achieved by the aid of the steel ball arranged on the inner wall of the nut body and the sleeve.
Description
Technical field
The utility model relates to a kind of fastening piece that can be antitheft, refers in particular to a kind of saw tooth structure anti-theft nut.
Background technique
When existing anti-theft nut is used for fastenings or member out of doors, because original anti-theft nut structure, only fill separately steel column or steel ball in the groove, still by other people dismounting, cause the stolen of article when this structure makes twisting power greater than certain moment of torsion such as the spanner with large size.
The model utility content
The technical problem that one, will solve
The purpose of this utility model is for the existing the problems referred to above of prior art, and the spy provides saw tooth structure anti-theft nut a kind of simple in structure, easily manufactured.
Two, technological scheme
For solving the problems of the technologies described above, the utility model saw tooth structure anti-theft nut, nut body is internal threaded nut, the inner surface of this nut has the skewed slot of arc, be provided with steel ball in the above-mentioned skewed slot, wherein, the outer wall of above-mentioned nut body is provided with raised line, be socketed with the sleeve that matches with nut body on the above-mentioned nut body outer wall, above-mentioned sleeve and raised line drive fit.
As optimization, above-mentioned raised line is jagged raised line.
As optimization, above-mentioned raised line is arranged on both sides corresponding to nut body outer wall.
Three, the beneficial effects of the utility model
The utility model adopts two designs of part of nut body and sleeve, when mounted, operator can screw in nut in the erection unit, and when later maintenance, if the burglar unscrews nut body by sleeve, when strength acquired a certain degree, sleeve can spin around nut body, can't unscrew nut body, thus the purpose that the steel ball by being arranged on the nut body inner surface and sleeve reach double anti-theft.
Description of drawings
Below in conjunction with accompanying drawing the utility model saw tooth structure anti-theft nut is described further:
Fig. 1 is the plan view of the utility model nut body;
Fig. 2 is the plan view of the utility model sleeve.
Among the figure, 1 is nut body, and 2 is raised line, and 3 is sleeve, and 4 is through hole.
Embodiment
Mode of execution one: as illustrated in fig. 1 and 2, the utility model saw tooth structure anti-theft nut, nut body 1 is internal threaded nut, the inner surface of this nut has the skewed slot of arc, be provided with steel ball in the above-mentioned skewed slot, wherein, the outer wall of above-mentioned nut body 1 is provided with raised line 2, be socketed with the sleeve 3 that matches with nut body 1 on above-mentioned nut body 1 outer wall, above-mentioned sleeve 3 and raised line 2 drive fits.
Above-mentioned raised line 2 is jagged raised line 2; Above-mentioned raised line 2 is arranged on both sides corresponding to nut body 1 outer wall.
In use, only need sleeve 3 is socketed on the outer wall of nut body 1, match in the outer wall of nut body 1 owing to be opened in the diameter of sleeve 3 middle through-holes 4, but the outer wall of 2 protrusions of above-mentioned raised line and nut body 1, above-mentioned sleeve 3 and raised line 2 drive fits.When screwing, operator can utilize manual mode that nut body 1 is pinned, and bolts and nuts body 1 are screwed get final product; And when later maintenance, if the burglar unscrews nut body 1 by sleeve 3, when strength acquired a certain degree, sleeve 3 can spin around nut body 1, can't unscrew nut body 1, thus the purpose that the steel ball by being arranged on nut body 1 inner surface and sleeve 3 reach double anti-theft.
More than above-mentioned only be preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
