Abstract
The utility model relates to a polygonal antitheft nut. When some antitheft nuts are used for clamping parts or components outdoors, only a steel column or a steel ball is independently mounted in a groove due to original structure of the antitheft nuts, the antitheft nuts of the structure can be demounted when wrenching force of a larger wrench is larger than a certain torque, and parts or components are then stolen. The polygonal antitheft nut is an inner-threaded nut, the inner wall of the nut is provided with an arc-shaped oblique groove, a steel ball is disposed in the arc-shaped oblique groove, the outer ring of the nut is polygonal, the number of the outer walls of the nut ranges from 5 to 16, a sleeve provided with a through hole in the middle is sleeved outside the nut, the inner wall of the through hole is an equilateral polygon matched with the outer ring of the nut, and the sleeve is in clearance fit with the nut. A dual-part structure of the nut and the sleeve is adopted, and dual antitheft effects are achieved by the aid of the steel ball on the inner wall of the nut 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 polygon structure anti-theft nut.
Background technique
When the anti-theft nut that has is used for fastenings or member out of doors, because original anti-theft nut structure only fills separately steel column or steel ball in the groove, when making twisting power greater than certain moment of torsion such as the spanner with large size, this structure still by other people dismounting, causes the stolen of article.
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 it is a kind of simple in structure, easily manufactured that the spy provides, and prevents the polygon structure anti-theft nut that the burglar steals.
Two, technological scheme
For solving the problems of the technologies described above, the utility model polygon 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, above-mentioned nut body outer ring is regular polygon, the outer wall quantity of above-mentioned nut body is X, 5≤X≤16, above-mentioned nut body is socketed with sleeve outward, and this sleeve middle part has through hole, the inwall of above-mentioned through hole is regular polygon, above-mentioned sleeve and the nut body Spielpassung that is complementary with the nut body outer ring.
As optimization, above-mentioned X=12.
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 polygon 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 the outer ring, and 3 is sleeve, and 4 is through hole.
Embodiment
Mode of execution one: as illustrated in fig. 1 and 2, the utility model polygon 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, above-mentioned nut body 1 outer ring 2 is regular polygon, the outer wall quantity of above-mentioned nut body 1 is X, 5≤X≤16 are socketed with sleeve 3 outside the above-mentioned nut body 1, and these sleeve 3 middle parts have through hole 4, the inwall of above-mentioned through hole 4 is the regular polygon that is complementary with nut body 1 outer ring 2, above-mentioned sleeve 3 and nut body 1 Spielpassung.
The numerical value of above-mentioned X can be 6,8,9,10 etc., the above-mentioned X=12 of present embodiment, that is and, nut body 1 outer ring 2 is dodecagon.
In the middle of using process, first sleeve 3 engage sleeves are connected on the nut body 1, then, utilize bolts and nuts body 1 to cooperate and be spirally connected, the object that will be fixed is fixed, and the operator utilizes first to receive nut body 1 is pinned, then screw bolt and get final product, because sleeve 3 and nut body 1 Spielpassung.
When being stolen by the people, the burglar can only unscrew nut body 1 by sleeve 3, because sleeve 3 and nut body 1 Spielpassung, when the burglar exerts all one's strength large to a certain degree the time, the polygonal of nut body 1 outer ring 2 can be worn, thereby can cause the phenomenon of skidding during rotational sleeve 3, thereby play antitheft effect.
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.
Claims (2)
1. polygon structure anti-theft nut, nut body is internal threaded nut, the inner surface of this nut has the skewed slot of arc, is provided with steel ball in the described skewed slot, it is characterized in that: described nut body outer ring is regular polygon, the outer wall quantity of described nut body is X, 5≤X≤16, described nut body is socketed with sleeve outward, and this sleeve middle part has through hole, the inwall of described through hole is regular polygon, described sleeve and the nut body Spielpassung that is complementary with the nut body outer ring.
2. polygon structure anti-theft nut according to claim 1 is characterized in that: described X=12.
