For solving the problems of the technologies described above, the invention provides a kind of anti-theft bolt, comprise: bolt top, first body of bolt, second body of bolt, the first nut and the second nut, the left end of described second body of bolt is provided with first through hole, described first body of bolt is connected on described first body of bolt by described the first through hole is dismountable, described second body of bolt and described first body of bolt are perpendicular, the top of described first body of bolt is fixedly connected on described bolt top, described the first nut and described first body of bolt are used in combination, described the second nut and described second body of bolt are used in combination.
In a preferred embodiment of the present invention, described first body of bolt comprises screw rod, middle screw rod and lower screw rod three parts, and described upper screw rod, middle screw rod and lower screw rod are fixedly connected sequentially, and the external diameter of described lower screw rod is less than the external diameter of described middle screw rod.
In a preferred embodiment of the present invention, described middle screw rod is provided with the first outside thread, and described the first nut inside is provided with the first internal thread matching with described the first outside thread.
In a preferred embodiment of the present invention, described lower screw rod is provided with smooth outer surface, and described external screw rod is provided with the second through hole.
In a preferred embodiment of the present invention, the right-hand member of described second body of bolt is provided with the second outside thread, and the inside of described the second nut is provided with the second internal thread matching with described the second outside thread.
The invention has the beneficial effects as follows: anti-theft bolt fastening strength of the present invention is high, using effect good, bearing capacity is strong.
Accompanying drawing explanation
In order to be illustrated more clearly in the technological scheme in the embodiment of the present invention, below the accompanying drawing of required use during embodiment is described is briefly described, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing, wherein:
Fig. 1 is the structural representation of anti-theft bolt one preferred embodiment of the present invention;
In accompanying drawing, the mark of each parts is as follows: 1, bolt top; 2, first body of bolt; 21, upper screw rod; 22, middle screw rod; 23, lower screw rod; 24, the first outside thread; 25, the second through hole; 3, second body of bolt; 31, the first through hole; 32, the second outside thread; 4, the first nut; 5, the second nut.
Embodiment
To the technological scheme in the embodiment of the present invention be clearly and completely described below, obviously, described embodiment is only a part of embodiment of the present invention, rather than whole embodiments.Based on the embodiment in the present invention, those of ordinary skills, not making all other embodiments that obtain under creative work prerequisite, belong to the scope of protection of the invention.
Refer to Fig. 1, the embodiment of the present invention comprises:
A kind of anti-theft bolt, comprise: bolt top 1, first body of bolt 2, second body of bolt 3, the first nut 4 and the second nut 5, the left end of described second body of bolt 3 is provided with first through hole 31, described first body of bolt 2 is connected on described first body of bolt 2 by described the first through hole 31 is dismountable, described second body of bolt 3 is perpendicular with described first body of bolt 2, the top of described first body of bolt 2 is fixedly connected on described bolt top 1, described the first nut 4 is used in combination with described first body of bolt 2, described the second nut 5 is used in combination with described second body of bolt 3.
In addition, described first body of bolt 2 comprises screw rod 21, middle screw rod 22 and lower screw rod 23 3 parts, and described upper screw rod 21, middle screw rod 22 and lower screw rod 23 are fixedly connected sequentially, and the external diameter of described lower screw rod 23 is less than the external diameter of described middle screw rod 22.Upper screw rod 21 is used for being fastenedly connected parts, and middle screw rod 22 prevents that fastening link from separating after being connected with the first nut 4, and second body of bolt 3 is fixed on lower screw rod 23, can effectively prevent that whole bolt is stolen.
