Description

Five jiaos of anti-theft nuts
Technical field
The utility model relates to a kind of fastening piece, especially relates to a kind of anti-theft nut.
Background technique
Fastening piece is for the indispensable part connected between mechanical part and device is fixed, in particular for being in the fastening piece in the Infrastructure in field, its Security more seems important, as the bolt and nut fastening piece used in the Infrastructure such as railway, highway bridge, electric power pylon, microwave communication tower.Existing conventional fastener nut is all generally have the four directions of corner angle, hexagonal or polygonal nut, this nut, as long as be removed easily with general tool.Existing threaded fastener, does not possess anti-theft feature, is easily disassembled and steals, not only can cause any property loss, also easily cause potential safety hazard, even can cause security incident time serious simultaneously.Existing anti-theft nut is common nut, and screw place is provided with groove, is provided with the structure of steel ball in groove, and the anti-theft nut of this spline structure exists anti-theft effect difference, the shortcoming that inner steel ball easily drops.
Model utility content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of deft design, good anti-theft effect, coordinates five jiaos of anti-theft nuts that special spanner uses.
To achieve these goals, the utility model provides a kind of five jiaos of anti-theft nuts, comprise nut body and be enclosed within the nut sleeve outside threaded body, it is characterized in that: described nut body is cylindrical taper, upper-end surface is provided with the binding groove for tightening nut, outer conical surface is provided with groove, centre is provided with cylindrical hole, described cylindrical hole is provided with screw thread, described screw thread is provided with arc groove, be provided with spring in described arc groove, described spring end is provided with steel ball, and described spring and steel ball are arranged in arc groove by butter; Described nut sleeve is inner conical, and described inner conical matches with the cylindrical taper of nut body; The internal conical surface of described nut sleeve is provided with boss, described boss be stuck in the groove of described nut body.
Further, described binding groove is wedge-shaped structure, and only playing fastening, described binding groove is provided with 2 ~ 6.
Further, described groove is 2 ~ 3.
Further, the outer surface of described nut sleeve is regular pentagon.
Further, there is chamfering at the tapped hole upper and lower port place of described nut body.
The utility model beneficial effect: the antitheft of spring steel ball is combined with the design of nut body taper the effect realizing double anti-theft, its structural design is exquisite, good anti-theft effect, coordinates special spanner to use, and is applicable to the fixing of various needs safe antitheft.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below:
Fig. 1 is structural representation of the present utility model.
In figure: 1. nut body; 2. nut sleeve; 3. spring; 4. steel ball; 5. binding groove; 6. groove; 7. boss.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further illustrated:
As shown in Figure 1, the utility model provides a kind of five jiaos of anti-theft nuts, comprise nut body 1 and be enclosed within the nut sleeve 2 outside threaded body 1, it is characterized in that: described nut body 1 is in cylindrical taper, upper-end surface is provided with the binding groove 5 for tightening nut, outer conical surface is provided with groove 6, centre is provided with cylindrical hole, described cylindrical hole is provided with screw thread, described screw thread is provided with arc groove, be provided with spring 3 in described arc groove, described spring 3 end is provided with steel ball 4, and described spring 3 and steel ball 4 are arranged in arc groove by butter; Described nut sleeve 2 is in inner conical, and described inner conical matches with the cylindrical taper of nut body 1; The internal conical surface of described nut sleeve 2 is provided with boss, and described boss 7 is stuck in the groove 6 of described nut body 1.
Further, described binding groove 5 is in wedge-shaped structure, and only playing fastening, described binding groove 5 is provided with 2 ~ 6.
Further, described arc groove is 2 ~ 3.
Further, the outer surface of described nut sleeve 2 is regular pentagon.
Further, there is chamfering at the tapped hole upper and lower port place of described nut body.
Nut body 1 is matched by inside and outside cone match with nut sleeve 2, the boss 7 that nut sleeve 2 is provided with is stuck in the groove 6 of nut body 1, namely when nut sleeve 2 opposing nut body 1 rotates, by boss 7 and groove 6 mating reaction, thus nut body 1 is driven to rotate.Be regular pentagon in conjunction with nut sleeve 2 outer surface, when nut be contained in bolt requires fastening time, coordinate special five jiaos of spanners to be enclosed within the regular pentagon outer surface of nut sleeve 2, pull spanner, nut sleeve 2 drives nut body to rotate together, thus reaches fastening effect.
After nut is relative to bolton, nut sleeve 1 is taken off.Because nut body 1 is in cylindrical taper, when nut body 1 will be pulled down, then adapted special spanner is needed to use.
The spring 3 that nut body 1 neutral threaded hole is provided with and steel ball 4, make nut can only be fastening relative to bolt, cannot removal, thus play anti-theft function.
The antitheft of spring steel ball is combined with the design of nut body taper the effect realizing double anti-theft by the utility model, reaches theftproof performance good, and structural design is exquisite, coordinates special spanner to use simultaneously, is applicable to the fixing of various needs safe antitheft.
More than show and describe basic principle of the present utility model, major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope, the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
