Description
Technical field
This utility model relates to bolt technical field, particularly a kind of anti-theft bolt.
Background technology
Bolt is the securing member that mechanical field is often used, and bolt generally comprises nut and threaded rod, when bolt is fixed, by twisting nut, is threaded in hole by screw rod and is fixed, and fixed structure is relatively stable.
nullAt present，Bolt on market，Threaded rod and nut are that integral type is arranged，After bolt is fixing，Nut is exposed at outside connector，Some lawless persons can pass through the instrument such as screwdriver or spanner and twist nut，Twist out by bolt，Then the object fixed is stolen，Market occurred in that a part of anti-theft bolt later，This anti-theft bolt is by split type to nut and threaded rod setting，Nut and threaded rod removably connect，When by being fixed with this anti-theft bolt，First with nut and threaded rod clamping，Threaded rod is threaded into hole it is fixed by twisting nut，Then nut of dismantling carries out antitheft，But this anti-theft bolt has a defect，Even if after threaded rod is screwed into screwed hole，After nut is removed，The draw-in groove of threaded rod is exposed，Lawless person still can pass through instrument，With these card slot fit，Then threaded rod is twisted，Back-out bolt，Then fixture is stolen.
It is therefore necessary to find a kind of new mode to solve this problem.
Summary of the invention
For above-mentioned situation, for overcoming the defect of prior art, the purpose of this utility model is just to provide a kind of anti-theft bolt, effectively solves the easily stolen problem stolen of traditional bolt.
nullThe technical scheme of its solution is，Including screw rod，Screw rod is provided with the first external screw thread，The upper surface of screw rod is provided with counterbore，The first female thread it is provided with in counterbore，Safe screw rod it is set with in counterbore，Safe screw rod is provided with the second external screw thread，Constitute the second external screw thread and the structure of the first female thread coupling，Safe screw rod upper end is provided with the nut of triangle，Nut platform it is connected between nut and safe screw rod，The base of nut is equipped with the first inside groove，Nut is provided with cylinder table，Nut platform fastens to have nut is fastened on interior nut shell，The second groove with nut formed objects and shape it is provided with in nut shell，Constitute the structure that the second groove can mate with nut，Second groove is provided with the elastic projection corresponding with the first groove，Constitute the second groove when coordinating with nut，Elastic projection is placed in the structure in the first groove，The bottom of the first groove is provided with threeth groove corresponding with cylinder table，Cylinder table is provided with dustproof shell，Fourth groove corresponding with cylinder table it is provided with in dustproof shell.
This utility model structure is ingenious, by the cooperation layer by layer between screw rod, safe screw rod, triangle nut, nut shell, dustproof shell, ensureing the safety of bolt, bolt of the present utility model will be unable to dismounting without special nut shell, it is therefore prevented that bolt is stolen.

Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in further detail.
nullProvided by Fig. 1 to Fig. 5，This utility model includes screw rod 1，Screw rod 1 is provided with the first external screw thread 2，The upper surface of screw rod 1 is provided with counterbore 3，The first female thread it is provided with in counterbore 3，Safe screw rod 4 it is set with in counterbore 3，Safe screw rod 4 is provided with the second external screw thread 5，Constitute the structure that the second external screw thread 5 mates with the first female thread，Safe screw rod 4 upper end is provided with the nut 6 of triangle，Nut platform 7 it is connected between nut 6 and safe screw rod 4，The base of nut 6 is equipped with the first inside groove 8，Nut 6 is provided with cylinder table 9，Nut platform 7 fastens to have nut 6 is fastened on interior nut shell 10，The second groove 11 with nut 6 formed objects and shape it is provided with in nut shell 10，Constitute the structure that the second groove 11 can mate with nut 6，Second groove 11 is provided with the elastic projection 12 corresponding with the first groove 8，Constitute the second groove 11 when coordinating with nut 6，Elastic projection 12 is placed in the structure in the first groove 8，The bottom of the first groove 8 is provided with threeth groove 13 corresponding with cylinder table 9，Cylinder table 9 is provided with dustproof shell 14，Fourth groove 15 corresponding with cylinder table 9 it is provided with in dustproof shell 14.
Described nut shell 10 is the one in square, regular pentagon, regular hexagon.
The diameter of described dustproof shell 14 is identical with nut platform 7.
When this utility model uses,
Screw rod 1 is inserted to be needed in bolt hole to be mounted, first external screw thread 2 of screw rod 1 and the screw-internal thread fit of required installation, but the smooth surface due to screw rod 1, there is no the aid of specialty so as to tighten with female thread and coordinate, because dependence aid, such as spanner etc, the nut being all and have corner angle coordinates, make spanner can turn power when turning, now safe screw rod 4 is placed in counterbore 3, make the second external screw thread 5 of safe screw rod 4 and the first screw-internal thread fit of counterbore 3, then pass through the nut 6 turning triangle, safe screw rod 4 is made to be screwed in counterbore 3, now continue to turn nut 6, safe screw rod 4 becomes one with screw rod 1, screw rod 1 is driven to rotate, screw rod 1 is made to tighten in required female thread.
The shape of nut 6 is generally four corner bolts, five corner bolts, hex bolts, and nut 6 of the present utility model is triangle, so needing to be equipped with special aid, and if for this kind of bolt, one special spanner is set, then seem and waste one's talent on a petty job, and waste resource.
This utility model is installing triangle nut 6 and dismounting triangle nut 6, use a nut shell 10, the second groove 11 it is provided with in nut shell 10, second groove 11 just coordinates with triangle nut 6, and the shape size of nut shell 10 is the one in common four corner bolts, five corner bolts, hex bolts, it is possible to realize turning by common wrench.
In order to better fix the screwing force of the second groove 11 and triangle nut 6, elastic projection 12 on the second groove 11 can coordinate with the first groove 8, elastic projection 12 is made to be stuck in the first groove 8, now the second groove 11 and triangle nut 6 can very tight being combined together, then pass through spanner and turn nut shell 10 to realize the rotation of screw rod 1.
Triangle nut 6 is provided with cylinder table 9, the 3rd groove 13 placing cylinder table 9 is had in first groove 8,3rd groove 13 has only to hold cylinder table 9, it is not necessary to coordinated by screw thread, it is only necessary to meet after elastic projection 12 coordinates with the first groove 8 and can normally turn.
After screw rod 1 installs, in order to protect screw rod 1, and it is possible to prevent dust, nut shell 10 is pulled down, nut shell 10 is replaced to be arranged on cylinder table 9 dustproof shell 14, the 4th groove 15 in antitheft shell 14 coordinates with cylinder table 9, dustproof shell 14 can be fastened on nut 6 by threaded engagement, stealer can also be caused fascination, when robber person is when stealing bolt, when dustproof shell 14 is pulled down, find that bolt does not take off, but it is left triangle nut 6, and triangle bolt does not have special nut shell 10 not disassemble, because completing also without special spanner.
In order to better arrange triangle nut 6, better ensureing that nut shell 10 can coordinate with nut and turn, better dustproof shell 14 coordinates with cylinder table 9 and turns, and is provided with nut platform 7 between safe screw rod 4 and nut 6.
Further, if person has nut shell 10, when installing bolt, it is possible to safe screw rod 4 is dismantled, only retain screw rod 1 itself, because the smooth surface of screw rod own, adopt common spanner also cannot dismantle, be further ensured that the safety of bolt.
This utility model passes through working in coordination between screw rod, safe screw rod, triangle nut, special nut shell, dustproof shell; and protection is further ensured that the safety of bolt layer by layer; making stealer find to remain futile after the strength that costs a lot of money, anti-theft is extremely strong.
