Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of anti-theft bolt, have screw rod and nut, it is characterized in that: the front end of described screw rod is with tapered end, and described tapered end and screw rod are the structures that is interlocked by dead bolt on the lock core and the groove on the screw rod.
The technical solution of the utility model can also be further perfect, and as preferably, the groove on the described screw rod is an annular.
As preferably, the groove on the described screw rod is a slot cut.
As preferably, be provided with internal thread, the threads engaged on described internal thread and the screw rod at the entrance point of described tapered end and screw rod socket.
The beneficial effects of the utility model are: simple in structure, easy to use, and the generation of the incident that can avoid theft effectively.

Accompanying drawing 2 is bolt arrangement figure of Fig. 1;
Accompanying drawing 3 is tapered end generalized sections of Fig. 2;
Accompanying drawing 4 is another state generalized sections of tapered end of Fig. 3;
Accompanying drawing 5 is that the A of Fig. 1 is to schematic representation;
Accompanying drawing 6 is another kind of bolt arrangement figure of the present utility model;
Accompanying drawing 7 is another bolt arrangement figure of the present utility model.
Embodiment
Below by embodiment also in conjunction with the accompanying drawings, the technical solution of the utility model is further described in detail.
Embodiment:
As Fig. 1, Fig. 2, Fig. 3, Fig. 4, shown in Figure 5, front end at screw rod has annular groove 11, at the threaded extending portion 12 in circular groove 11 back, screw thread on the extending portion matches with the internal thread 21 of tapered end entrance point, there is dead bolt 31 lock core 3 fronts, when dead bolt 31 stretches out forward, just in time be interlocked with screw front end circular groove 11; Groove 13 shown in Figure 5 is a slot cut, does not have the extending portion of screw thread in the slot cut back; Groove 11 shown in Figure 6 is an annular groove, but the back does not have the extending portion of screw thread; The entrance point of the lock core that matches with Fig. 5 screw rod shown in Figure 6 does not have internal thread.
During use, tapered end need only be enclosed within above the screw rod, or threaded together, with key or rotate password by hand, the dead bolt on the lock core be stretched out, the groove that fastens on the screw rod gets final product; If unclamp object, need only or rotate password by hand with key, lock core and the dead bolt that links to each other with lock core is overhanging, can throw off bolt and unclamp object.The utility model goes for needing the various bolts of antitheft protection, as automobile tire fastening screw trip bolt, automobile storage battery fastening screw trip bolt etc., is used for automobile tire when antitheft, and every tire need only get final product with one.
