Those skilled in the art is in order to prevent this type of nut and other fastener product to be used by people clamp or spanner is stolen, often nut is designed to extremely complex or non-removable, usually, such nut is when needs are disassembled, also it is very difficult to dismounting, wastes time and energy or even non-dismountable.
In consideration of it, providing a kind of demountable anti-loose anti-theft nut and chuck thereof is the problem that this utility model is studied.
Summary of the invention
This utility model provides a kind of anti-loose anti-theft nut and chuck thereof, its objective is so that this nut is when without dismantling, it is difficult to dismounting；When needs are dismantled, adopt supporting instrument, convenient disassembly.
In order to achieve the above object, the technical solution of the utility model is: a kind of anti-loose anti-theft nut, including nut body, this nut body is provided with screwed hole of centre, its innovative point is in that: described nut body is set to round platform or terrace with edge structure, the outer surface of described nut body is provided with at least two leptosomatic grooves or convex tendon, described groove or convex tendon along the circumferentially-spaced layout of nut body, and the extending direction of the flute length direction of groove or convex tendon with the slant height direction of nut body consistent.
Further, the outer surface of described nut body is provided with two grooves or convex tendon.
Further, the outer surface of described nut body is provided with three grooves or convex tendon.
Further, the outer surface of described nut body is provided with four grooves or convex tendon.
Further, described anti-theft nut screw thread form can be triangle, rectangle, zigzag, circular arc etc..
In order to achieve the above object, another kind of technical scheme of the present utility model is: a kind of anti-loose anti-theft nut chuck, match with above-mentioned anti-loose anti-theft nut, including Gripper body, this Gripper body is provided with a hollow bulb, this hollow bulb and the size of anti-loose anti-theft nut, mating shapes, and described Gripper body is set to Rotary-table or cylinder or prism structure, on Gripper body, bottom surface, side opening is arranged, and Gripper body offers one on opposite side bottom surface and puts forth effort hole；
The inner surface of described Gripper body is provided with at least two convex tendons matched with groove or the convex tendon of nut body or groove, described convex tendon or groove are arranged along the inner circumferential uniform intervals of Gripper body, and the flute length direction of the extending direction of convex tendon or groove with the slant height direction of Gripper body consistent.
Further, described hollow bulb is truncated cone-shaped or prismatic table shape structure.
Further, described hollow bulb is cylindrical or prismatic structures.
In such scheme, in process of production, anti-loose anti-theft nut carries out surface heat cure process, it is possible to be effectively ensured the hardness of nut.
In such scheme, anti-loose anti-theft nut may also take on the collocation of groove and convex tendon and arrange, corresponding chuck also takes the collocation of convex tendon and groove to arrange.
Utility model works principle is: increase leptosomatic groove or convex tendon on the outer peripheral face of nut body, the groove or the convex tendon that so design have the clamping face making common clamp or spanner and can not put in groove or block convex tendon, have reached the purpose being difficult to be unloaded lower nut by stranger；When really needing to dismantle this nut, by collet sleeve outside nut, by the convex tendon outside the groove on nut body or convex tendon and Gripper body or fit depressions, (convex tendon of chuck is stuck in the groove on nut, or the convex tendon on nut is stuck in the groove of chuck), when chuck pulled by spanner, chuck drives nut to rotate, thus easily unloading lower nut.
Owing to such scheme uses, this utility model compared with prior art has the advantage that
A kind of anti-loose anti-theft nut provided due to this utility model and chuck thereof, it is different from general anti-theft nut, leptosomatic groove or convex tendon is increased at its outer surface, avoid the impetus of common pliers and spanner, when needs unload this nut time, by collet sleeve on this nut, then special spanner (torque spanner) is coordinated to use, can pull down nut simply and easily, this utility model simple in construction, with low cost but theftproof performance good.
