Description
Technical field
The utility model belongs to the nut technical field, relates in particular to a kind of anti-theft nut and is used to install and remove the special-purpose cannulated sleeve of this anti-theft nut.
Background technique
It is to be widely used in mechanical structure, project installation fixed object and the common and general mode of structure of article that bolt and nut connects, and has especially used screw bolt and nut to fix in a large number on facilities such as electric power, communication, iron tower, highway, bridge.Because conventional nut all is the hexagonal profile, be very easy to during installation and removal, use common wrench or pliers just can implement, there is no anti-theft feature.Therefore the nut of all communal facilitys under the no supervision situation is easy to be disassembled pilferage out of doors, causing damage and make troubles for the people's life and national wealth, is the problem that people explore always so adopt effective theft-prevention structure on the nut of installing connects.
At present common antitheft mode has the nut weldering extremely on bolt or connected piece, has plenty of to destroy that screw thread prevents to dismantle, and the nut of the design that also has is being screwed to the non-detachable disposable anti-theft nut in back on the screw rod.Though above antitheft mode has certain antitheft effect, because these antitheft modes and anti-theft nut all exist defective, can not dismantle after feasible the installation, safeguard for normal dismounting and bring difficulty.
Summary of the invention
The purpose of this utility model is to solve the deficiency of above-mentioned existence, and provide a kind of simple in structure, easy to use, theftproof performance is good and reusable novel anti-theft nut and special-purpose cannulated sleeve.
For solving above-mentioned technical problem, the utility model by the following technical solutions:
A kind of anti-theft nut comprises female nut body is set that this nut body outer surface is smooth solid of rotation, and an end face of solid of rotation is provided with the interior platform of " V " font that an energy is driven by sleeve, and interior profile of platform is " V " font structure in this.
Described solid of rotation is frustoconic shape, cylindrical, waist drum convex or waist drum spill.
Profile is arranged on the bigger end of anti-theft nut diameter for the interior platform of " V " font structure in described.
Profile is arranged on the less end of anti-theft nut diameter for the interior platform of " V " font structure in described.
The matching used special-purpose cannulated sleeve of a kind of and above-mentioned anti-theft nut comprises cylindrical shell, bulge loop and tube head; Described cylindrical shell profile is set to conventional hexagon nut profile or four-prism shape, and cylindrical shell, external frame that a described tube endoporus is a cylindrical surface structure be " V " font architecture, with the interior profile phase coupling of platform in anti-theft nut fit mutually also.
The utility model mainly is the deficiency that connects pattern at conventional bolt, and a kind of anti-theft nut and the matching used with it special-purpose cannulated sleeve of exploitation.This anti-theft nut appearance adopts frustoconic shape, cylindrical, waist drum convex, waist drum spill or other smooth solid of rotation, at an end face of solid of rotation " V " that an energy driven by sleeve platform in the font is set, inside remains the worm structure of standard, this nut is installed on the bolt of standard, screws or adopt when unclamping nut matching used special-purpose cannulated sleeve.This sleeve epimere is set to conventional hexagon nut profile or four-prism shape, and the endoporus of hypomere tube head is the cylindrical shell of cylindrical surface structure, and external frame be " V " font architecture, with the interior profile phase coupling of anti-theft nut fit mutually also.
Screw or when unclamping anti-theft nut, at first sleeve tube head is inserted in the sidewall of platform in the anti-theft nut,, can pass the sleeve endoporus, entangle the sleeve cylindrical shell with conventional spanner then, just can screw or unclamp anti-theft nut if screw rod is longer.The application of anti-theft nut, increased the difficulty of dismounting, therefore, had only with above-mentioned special-purpose cannulated sleeve supporting with the interior platform of " V " font structure that constitutes anti-theft nut, could mount and dismount anti-theft nut, guarantee the safety of parent member most possibly.
Compared with prior art, the beneficial effects of the utility model are mainly reflected in: advantage such as simple and reasonable for structure, easy to use, that anti-theft is superior, reached the non-effect that should the special use cannulated sleeve can not install and remove anti-theft nut, and this anti-theft nut can reuse, and promptly saves cost and reduces the wastage again.

Embodiment
Be described in further detail below in conjunction with the structure and the use principle of accompanying drawing anti-theft nut described in the utility model and special-purpose cannulated sleeve.
As Fig. 1, Fig. 2 and shown in Figure 3, first kind of structural representation for anti-theft nut described in the utility model, it comprises that one is provided with the nut body 1 of internal thread 4, the outer surface of this nut body 1 is smooth frustoconic shape, the less end of this round platform diameter is provided with platform 2 in " V " font, and interior profile 5 of platform 2 is " V " font a structure in this.
As Fig. 4, Fig. 5 and shown in Figure 6, second kind of structural representation for anti-theft nut described in the utility model, it comprises that one is provided with the nut body 1 of internal thread 4, the outer surface of this nut body is smooth frustoconic shape, the end that this round platform diameter is bigger is provided with platform 2 in " V " font, and interior profile 5 of platform 2 is " V " font structure in this.
As shown in Figure 7, for the matching used special-purpose cannulated sleeve structural representation of above-mentioned anti-theft nut, it comprises cylindrical shell 6, bulge loop 9 and tube 7.Bulge loop 9 is arranged between cylindrical shell 6 and the tube 7, and the external diameter of bulge loop 9 is greater than the external diameter of cylindrical shell 6 and tube 7.Bulge loop 9 is used in use spanner being positioned, and the profile of cylindrical shell 6 is conventional hexagon nut profile or four-prism shape, so that can use conventional Wrench to carry out the screwing or unclamp of anti-theft nut increased the convenience that the user uses.The external frame of tube 7 be " V " font architecture, and with the interior profile 5 of platform 2 in the above-mentioned anti-theft nut fit mutually that is complementary also, sleeve endoporus 8 is the cylindrical shell of the cylindrical surface structure corresponding with anti-theft nut central cylinder 3 diameters.
In other embodiments, anti-theft nut described in the utility model, its nut 1 also can be a kind of solid of rotation in cylindrical, waist drum convex or the waist drum spill.One end face of described solid of rotation is provided with the interior platform of " V " font that an energy is driven by sleeve, and interior profile of platform is " V " font structure in this.
During use, anti-theft nut described in the utility model is screwed on the bolt of standard, as shown in Figure 1 and Figure 4, the one side of platform 2 is outside in wherein being provided with, the tube 7 of socket wrench specially adapted for it is inserted in the sidewall of platform 2 in the anti-theft nut,, can pass sleeve endoporus 8 if screw rod is longer, entangle sleeve cylindrical shell 6 with conventional Wrench then, can carry out screwing or unclamp anti-theft nut.Anti-theft nut adopts the frustoconic shape do not have the corner, can not tighten on the profile of nut and can't turn nut with general conventional tool, has only by this special use cannulated sleeve and it could be screwed or unclamp.So can improve its theftproof performance greatly.In addition, general employed screw rod is longer, all exceeds nut end face, and the space that the platform sidewall forms in screw rod and the anti-theft nut is minimum, can not nut be prized with other instruments, thereby reach antitheft effect.The application of anti-theft nut has increased the difficulty of dismounting, if should the special use cannulated sleeve, is difficult to anti-theft nut is mounted and dismounted, and has guaranteed the safety of parent member most possibly, prevents fixedly losing of article.
