The utility model relates to a kind of antitheft, waterproof warning chain (rope) lock.

Existing all kinds of chains (rope) lock, generally employing or pick-proof or anti-alarm device only have antitheft simple function.CN2131931Y has announced a kind of " double-stranded bar alarming lock ", and it is made up of chain (rope) bar, tapered end, locking bolt body (seat), break alarm circuit.But locking bolt body (seat) structural change, technology difficulty is bigger, and tapered end, and the locking bolt body is exposed, and lock core is easily immersed by rainwater and damages, and increases the warranty charges to lock.

The purpose of this utility model is to avoid above-mentioned deficiency of the prior art, provides a kind of and draws materials easily, and combination processing is simple, warning chain (rope) lock of not only antitheft but also waterproof.

The purpose of this utility model can reach by the following technical programs: a kind of warning chain (rope) lock, tapered end, locking bolt (seat) and comprise that the break alarm circuit of battery, loudspeaker forms, but also comprise a warning box, casing is provided with chain (rope) and penetrates hole and loudspeaker sound hole, adopts combination lock to realize lid or the position that opens or closes; The tapered end that casing is equipped with, warning circuit, battery and loudspeaker are formed loop apparatus with closed chain (rope).As chain (rope) disconnected taking off under improper situation, break alarm circuit drives loudspeaker sends chimes of doom.

The utility model contrast prior art has following advantage:

1, can adopt market to have chain (rope) lock and be main body and easy processing accessory, the outsourcing piece combinations produce need not complex device, can go into operation.

2, principle is simple, and is rational in infrastructure, owing to adopt alarm to be provided with warning box, has the double insurance function, and warning box is sealed tapered end and prevented that lock core from being immersed by rainwater, so waterproof action is arranged, reduces the maintenance cost to lock, prolongation chain (rope) application life.

3, easy to operate, be suitable for and make motorcycle, automobile (steering wheel is fixed), tricycle, bicycle and important place, warehouse, factories and miness, the anti-lock of usurping in gate, workshop.

Fig. 1 is warning chain (rope) lock construction schematic diagram;

Fig. 2 is warning chain (rope) lock break alarm schematic diagram.

The utility model embodiment is explained as follows in conjunction with the accompanying drawings:

Warning box (1) is realized lid (2) or is opened or closed state with combination lock (11).Tapered end (7) screw and warning box (1) medial surface fixed connection, the junction corresponding side surface has chain (rope) and penetrates the hole, alarm element (3), loudspeaker (4), electronic switch (5) and battery (6) snap in case inner bottom part position with fixed support, loudspeaker (4) contact casing place has sound hole, and the warning box appearance is provided with the hook (not shown) that is fixed in the locked object body and function.If open former closed locking bolt (seat) (9), must earlier switch be dialled to " breaking " word with key (8), can take out chain (rope).If close closed chain (rope) lock with key (8), earlier chain (rope) is penetrated and insert tapered end in the case, extract key (8) out, switch dialled check the number and buckled lid (2), group random number again to " lead to " word, combination lock (11), warning box is closed, and alarm is in running order.As harm, chain (rope) is disconnected to be taken off, and the break alarm circuit drives loudspeaker (4) immediately and sends chimes of doom.
