When key turns clockwise lock core when promptly unblanking, action lever on the lock core drives the transmission levers and the push rod of cone both sides, push rod makes ball be pressed on the center-pole on the one hand, helps ball not fall down on the other hand, and the weight of ball moves down center-pole, the alarm armature contact is separated from fixed contact, thereby the breaking alarm circuit, meanwhile, lock core drives on dead bolt, dead bolt pin and the tapered end lock and moves, lock openedly, bicycle can be ridden.

During the lock car, at first tapered end is inserted in the tapered end hole, and lock housing set upright be horizontal level, with key lock core is rotated counterclockwise then, action lever on the lock core breaks away from transmission levers, transmission levers is returned to original position under spring action, push rod is backed off, and no longer helps ball, meanwhile, in the pin-and-hole on the dead bolt pin insertion bulb base bulb, dead bolt snaps in the outer casing groove, and the tapered end lock is clamped tapered end.

When the moving lock of burglar, motor-car or the disconnected chain go-cart of card are walked, be that the burglar makes lock housing vibration or when tilting, originally the ball that was positioned on the center-pole will be along being rolled into the push rod place under the cone inclined-plane, at this moment, center-pole rises under the effect of spring, the alarm armature contact contacts with fixed contact, thereby alarm is thundered.

The utility model is used for bag when antitheft, and only needing increases a pair of stable pin on the bulb base, the bulb base can be laid in the plane get final product.At this moment,, tapered end is inserted in the tapered end hole, can prevent that bag is stolen as long as chain is passed bag.

The utility model is used for drawer when antitheft, not chain and bulb base portion, and the drawer type lock box is replaced by drawer itself, and lock housing is replaced by drawer frame, has the slotted eye for the insertion of dead bolt pin on the drawer frame.

Compared with the prior art, the utility model has following characteristics:

1, reports to the police in time reliably, can prevent the auto theft behavior effectively.

Lock is opened with key if not owner, ball will be on the center-pole, remain one and touch the situation of promptly rolling, at any time warning be might cause, pick-proof, tamper, anti-saw, anti-hammer really accomplished, because have a guilty conscience, the burglar often dare not steal car after hearing sound, moreover the onlooker knows that also the people of motor-car is not the owner of car, can in time prevent the auto theft behavior.

2, easy for installation, easy to maintenance.

The utility model only need be installed on the back fork of bicycle and get final product.When lock was in open mode, dead bolt broke away from lock housing and in the indentation lock box, whole lock box can be released in lock housing, changed maintenance works such as battery.

3, because chain is a soft body structure, can lock together bicycle and railing, pillar class fixture, in case move.

4, purposes is many, not only is used for bicycle anti-theft alarm, can also be used for bag drawer burglar alarm, and promptly a lock uses.
