Abstract

The utility model discloses a bicyclelock with acoustic alarm, which is a vehicle lock of sounding alarm, and the vehicle movement or picking the lock makes the sound when in locked status and placing at the alarming position. The utility model comprises a bicycle lock and an alarming device. When the vehicle lock is locked, the power supply is communicated at the same time, the vehicle movement or picking the lock makes the contact of the alarming device be communicated, sounding alarm and causing people's attention. The bicyclelock with acoustic alarm is also connected with a push-button switch, serving as electric loudspeaker for vehicle.

Description

Bycicle lock with acoustic alarm

The utility model is the sounding alarm anti-theft vehicle lock that is used for bicycle.

In the prior art, various locks have only the function, particularly bicycle of pinning wheel, under the situation that trailing wheel pins, still have and lift trailing wheel slightly and be pushed away or pry open the situation that lock is stolen.

The purpose of this utility model is the lock of design-calculated band generation warning device for the vehicle that prevents to pin is stolen.

The utility model partly is made up of lock partial sum sounding alarm.The power supply of sounding alarm device is that the motion by two cams realizes.Actuating cam (3) is that the garden has a projection on week, and inverted cam (4) then is two place's projectioies on the plane, goes up each place of convex-concave garden week.When lock during at locked position, among Fig. 1, lock ring clamp (1) blocks lock ring (2), with lock key control cam (3), (4) left-hand revolution, the salient point of actuating cam (3) drives inverted cam (4) corresponding actions, when the recess of cam (4) and source switch spring leaf (5) when being meshed, the end of spring leaf (5) contacts K among Fig. 2 with spring leaf (6) is terminal ₁Closure, the warning power connection.Warning device adopts the relay latching circuit, as Fig. 2.The structure of motion alarm is that the motion primary element welds tin stone roller (7) by a fixed length spring wire top, is limited in the minor diameter naked cable circle (8), becomes the open contact K in the warning circuit ₀When car moved, spring top tin stone roller (7) vibration drove steel wire and naked cable circle and collides K ₀Connect, make relay work and self-locking, dynamic loud-speaker sends continuous alarm sound.Have only with car key K ₁During disconnection, chimes of doom can stop.The structure of Pickproof alarm is when lock pins, and the terminal salient point jack-up pick-proof of lock ring (2) triggers spring leaf (9).When lock was prized, lock ring rebounded, and salient point leaves

Pick-proof triggers spring leaf (9), and reed (9) is subjected to the elastic force effect to get back to the home position, and reed this moment (9) contacts with the end of reed (10), i.e. K ₃Connect, trigger and report to the police.Warning device has a light-emitting diode to do the indication of work state.The movement that circuit card and power supply are formed, the garden week salient point jack-up insurance push rod (11) of cam when alert locations (4) is locked in movement in the shell.For the bicycle bell that makes warning device can make vehicle uses, adorn a button switch K ₂, dynamic loud-speaker is used in the time of can driving a vehicle.

Compared with the prior art, the utility model is that bicycle lock has increased the sounding alarm function, and lock and warning device join together, and by push rod movement are locked in the shell, are difficult for destroyed.The sealing of sense of motion element vertically is installed on the movement, experiences movement sensitive, reliable, and the tin stone roller of spring top welding is limited in the minor diameter naked cable circle, and is not yielding.Warning device is made the work state with light-emitting diode and is shown, easy to use, power consumption is lacked.This device both can be reported to the police, and also can make dynamic loud-speaker and use.

Description of drawings: Fig. 1 is a sounding alarm bicycle lock overall schematic.

Fig. 2 is the sounding alarm circuit diagram.

The certain thickness iron plate punching out of the utility model embodiment shell, the warning movement is circuit card, power supply and to experience motor element cased, be screwed, and by the pinning of insurance push rod, become closed state, lock ring clamp (1), cam (3), (4), insurance push rod (11) is used the iron plate punching out.Spring leaf (5), (6), (9), (10) make of phosphorus bronze sheet.Circuit is formed by light-emitting diode, relay, resistance, dynamic loud-speaker connection.The naked cable circle of experiencing on the motor element is made of bare copper wire, and silver-plated.

Claims

1, a kind of lock that has warning device is made up of power supply, warning device, circuit and lock, it is characterized in that source switch is had the mutual action control of actuating cam (3) with the inverted cam (4) that projection is all arranged in plane, garden week of a projection on week by the garden; Pick-proof triggers spring leaf (9) and is controlled by lock ring (2); The element that the car motion is stolen in impression is by naked cable circle (8) and be limited in spring wire top welding tin stone roller (7) formation in the circle.

2, according to the described sounding alarm lock of claim 1., its special card is that source switch contact (5) (6) and pick-proof contact (9) (10) are to make with phosphorus bronze sheet.
