CN2595950Y - Sound and light type theft-proof bicycle lock - Google Patents

Abstract

The utility model relates to a sound and light type theft-proof bicycle lock. A battery, a red bulb, an electric whistle, a vibrating switch, and an interlock switch are added and arranged on the basis of a mechanical bicycle lock. After the bicycle lock is locked when the bicycle lock is pried or a bicycle is removed, the vibrating switch is closed. Then, the red bulb and the electric whistle are switched on. The red bulb sends out red light and the electric whistle sends out alarm sounds for stopping robbery. A key forms a bidirectional tooth shape for preventing the lock from drawing out by conventional methods.

The acousto-optic anti-theft bicycle lock

Affiliated technical field

The utility model relates to bicycle lock

Background technology

Present bicycle lock all is to rely on mechanical part antitheft, and anti-theft capability is limited, lacks warning device, and the cartheft employing is drawn lock, picking lock or simply the bicycle of locking shouldered away.The stolen rate height of bicycle, townsfolk almost each household has bicycle stolen.

The utility model content

The utility model is in order to overcome above-mentioned shortcoming, a kind of acousto-optic anti-theft bicycle lock is provided, after on bicycle lock, if artificial picking lock is arranged or moves bicycle, acousto-optic anti-theft device in the lock will send the ruddiness and the chimes of doom of flicker, reminds people has the people to attempt to steal car, and cartheft is had deterrent effect.

The utility model is to lock at traditional mechanical bicycle to have installed the sound-light electrical control element additional, becomes the lockset of electromechanical integration.The negative pole of battery connects the movable contact of interlocking switch by electric wire, the stationary contact of interlocking switch connects the movable contact of vibroswitch by electric wire, the stationary contact of vibroswitch is by an end of electric wire connection red light bubble and electric whistle, and the other end of red light bubble and electric whistle is connected to the positive pole of battery.Interlocking switch in the time of on bicycle lock in the lock closes, and bicycle is in inactive state, and the movable contact of vibroswitch is in the centre position, and vibroswitch is in separated position.When bicycle when not unblanking, lock is prized, or bicycle by the people for moving, the movable contact of vibroswitch is just constantly closed with stationary contact and separates because of vibrating, blinking red lamp, and electric whistle sends chimes of doom simultaneously, come into the picture, the deterrence cartheft stops stealing car.

When the car owner uses vehicle, open the acousto-optic anti-theft bicycle lock with key, interlocking switch is opened, and electric control loop disconnects, and vibroswitch closes during the bicycle operation, and red light bubble and electric whistle are in power failure state.Can not send acousto-optic in the lock.When lock was locked, the baffle plate on the locking bolt blocked the battery cover board screw, prevented to steal battery.When lock was opened, available bottle opener screwed off the battery cover board screw.Take off battery cover board and change battery.Key is a bidirectional tooth form, prevents to draw lock with conventional method.

The specific embodiment

In Fig. 1, battery (6), interlocking switch (5), vibroswitch (7), electric whistle (3), red light bubble (4) are formed the acousto-optic anti-theft alarm circuit.After the handle of locking bolt (8) is pressed; the groove of locking bolt (8) is pushed down by the cam of lock core (1); it pushes down the moving point of interlocking switch (5) simultaneously, and interlocking switch (5) is in on-state, and the baffle plate of locking bolt (8) blocks battery cover board screw (9) protection battery cover board (10) and is not opened.If lock is subjected to unusual fluctuation, vibroswitch (7) is connected, and the electric current of battery (6) sends ruddiness through interlocking switch (5) and vibroswitch (7) through red light bubble (4), and electric current passes through electric whistle (3) simultaneously and sends chimes of doom.When key (14) enters lock core (1) half-twist, the cam that lock core (1) connects leaves the groove of locking bolt, spring (11) is locking bolt (8) pop into position, lock is opened, the cam of lock core (1) connection is simultaneously pushed down interlocking switch (5), makes it be in separated position, and circuit disconnects, bicycle is in when operation, and vibroswitch (7) closes and also do not have acousto-optic and send.Front shroud (12) and back shroud (13) are the shells of bicycle lock, when car door opening, can back out battery cover board bolt (9), take off battery cover board (10) and change battery (6).

Claims (2)

1, form the circuit of reporting to the police by battery, red light bubble, electric whistle, vibroswitch, interlocking switch in a kind of acousto-optic anti-theft bicycle lock, lock, key is a bidirectional tooth form.It is characterized in that forming the circuit of reporting to the police by battery, red light bubble, electric whistle, vibroswitch, interlocking switch in the lock.

2, acousto-optic anti-theft bicycle lock according to claim 1 is characterized in that key is a bidirectional tooth form.
