The lock control anti-theft alarm for a bicycle can effectively prevent a bicycle stolen event from happening.

Description

Anti-theft alarm for bicycle lock

The utility model belongs to warning device, particularly a kind of lock control of bicycle use vibration burglar alarm.

Current, the main anti-theft measure of bicycle is a lock, and its function is to stop the robber that bicycle is pushed away away.But bicycle itself is not too heavy, and a people can carry, so lock has and can't stop the robber under the situation of not unblanking, the shortcoming that bicycle is carried away.

The purpose of this utility model provides a kind of when the robber carries bicycle, because of vibration moment or can send the bicycle lock control burglar alarm of alarm sound at the appointed time, makes the car owner can in time realize and prevent the purpose that bicycle is stolen.

The purpose of this utility model is achieved through the following technical solutions: this bicycle lock control burglar alarm comprises box body, bottom (backboard), is contained in in-to-in lock control devices and warning circuit, is characterized in also being provided with in box body vibrating sensing mechanism.

This vibrating sensing mechanism, a kind of structure wherein be by on the wall within it for step-like cylindrical shell, loam cake and be contained in extension spring in the cylindrical shell from top to bottom, heavily stone roller, bar magnet and induction coil constitute.Loam cake can tighten up with cylindrical shell and be connected, and extension spring upper end hangs on the loam cake bottom surface, and its lower end is connected with heavy stone roller, is the bar magnet of captiveing joint with it below heavily cutting or polish jade with an emery wheel, and induction coil is contained on the bar magnet cylinder inboard wall on every side.Also correspondence has two vertical cores and communicates with its middle part cavity in cylindrical shell upper chamber both sides, in conduction contact block and fixing stage clip are housed.

Lock control devices is made of lock and transmission device and the button switch adaptive with it.

Above-mentioned transmission device tightens up the bonded assembly synchronizer gear by the lock core lower end and bonded assembly transmission gear and drive link constitute successively.Have above drive link one end with it that the all-in-one-piece projection can contact with the bar magnet bottom surface, its other end is that tooth bar is connected with transmission gear.When unblanking with lock, because of rotating by synchronizer gear and transmission gear, lock core drives the drive link up-and-down movement, and move contact when unblanking on the drive link and hold up bar magnet, promptly close vibrating sensing mechanism; Otherwise drive link moves down the disengaging bar magnet, promptly opens vibrating sensing mechanism.Button switch by on inwall by the button cavities of boss be contained in in-to-in button, button spring, reed and stop gear along axis and form.Button is provided with and its all-in-one-piece ring-type pressing plate by the upper end, and there is conductive layer the middle and lower part, and position-limited trough is arranged at the bottom.Button cavities is cooresponding two and tightens up and be formed by connecting.The button spring is contained between pressing plate and the boss in the cavity, and reed is cooresponding two and is contained between the boss and matches with conductive layer.

Stop gear is made of the position-limited trough on locating dowel pin, limit spring and the button of limiting bracket and horizontal top loading.Locating dowel pin is " L " shape, and an end passes the button cavities wall and cooperates with position-limited trough, and its other end cooperates contact to be connected with dead bolt.

The utility model compared with prior art have report to the police sensitive, fast, reliable, in the robber moves moment of car or specified time, can send alarm sound, can effectively prevent the generation of the stolen incident of bicycle.

The utility model accompanying drawing drawing is described as follows:

Below in conjunction with embodiment (accompanying drawing) the utility model is further described:

As Fig. 1-shown in Figure 5: the utility model by rectangular box body 1 and the bonnet (backboard) that is mated, be contained in in-to-in lock control devices, vibrating sensing mechanism and warning circuit and constitute, be installed on the back fork of bicycle, i.e. the position of dress lock usually.Vibrating sensing actuation mechanism (Fig. 4) by the cylindrical shell 14 that step 16,19 is arranged on the wall within it, loam cake 24, the inner extension spring 20 that is provided with from top to bottom, heavily cut or polish jade with an emery wheel 18, bar magnet 17 and induction coil 15 constitute.The upper end of extension spring 20 is mounted on the bottom of loam cake 24, the lower end with heavily cut or polish jade with an emery wheel 18 and be connected, bar magnet 17 tightens up with it below heavily cutting or polish jade with an emery wheel 18 and is connected, induction coil 15 be located at bar magnet 17 around.Correspondence has two vertical cores 23 and communicates with middle cavities on the cylindrical shell 14 on epicoele both sides, in conduction contact block 21 and fixing stage clip 22 are housed.Lock drawing device (Fig. 3, Fig. 2) is made of lock and the transmission device and the button switch that are mated.Transmission device is made of the transmission gear 6 and the drive link 11 of synchronizer gear 3 that is fixed tightly in lock core 4 lower ends and flexible connection successively.Have above drive link 11 1 ends with it can to contact with the bottom surface of bar magnet 17 for the projection 12 of one, its other end is that tooth bar and transmission gear 6 flexibly connect.Button switch is made up of button cavities 25, button 26, button stage clip 30, reed 28, conductive layer 32 and stop gear.Button cavities 25 tightens up and is formed by connecting for cooresponding two, and wall is provided with boss 27,29 within it.Button stage clip 30 is contained between boss 29 and the button pressing plate 31, promptly button 26 around.Reed 28 also is cooresponding two, is contained on the chamber wall between the boss 27,29, matches with conductive layer 32 on the button 26.Stop gear is made of the position-limited trough 33 that limiting bracket 8 and level are contained on limit spring 9, locating dowel pin 7 and the button 26 above it.7 one-tenth " L " shapes of locating dowel pin, the chamber wall that an end passes button cavities 25 cooperates with position-limited trough 33, and its other end cooperates contact to be connected with dead bolt 5.Also be provided with lock ring jack 2 and lock ring putting hole 34 on the box body 1.Warning circuit figure (Fig. 5) is a known technology, becomes to electrically connect with button switch with vibrating sensing mechanism.K is a button switch, i.e. source switch, and the one end is connected with battery 13, and the other end is connected with circuit.K1 is a switch-dividing, by the conduction contact block 21 of vibrating sensing mechanism with heavily cut or polish jade with an emery wheel 18 and constitute.

Working process of the present utility model and principle: button switch K (source switch) is respectively by K1 and induction coil 15 and warning circuit UNICOM.The car owner drives the transmission device action because of lock core 4 rotates when opening lock use bicycle, move on the drive link 11, and projection 12 holds up bar magnets 17 and makes its fixing can not displacement up and down, and promptly vibrating sensing mechanism closes.The rotation of the dead bolt 5 simultaneously and locating dowel pin 7 of stop gear and position-limited trough 33 are thrown off, button 26 moves under the 30 elastic force effects of button stage clip, and its conductive layer 32 and reed 28 are broken away from, and promptly button switch K is closed, power supply and circuit disconnect, and warning circuit can not worked and can not be sent alarm sound.On the contrary, when the car owner parks car when locking lock and pressing the button 26, the vibrating sensing mechanism opening, button switch K is closed, energized.At this moment move bicycle if any the robber, when making it have vibration to produce, bar magnet 17 moves up and down with heavily cutting or polish jade with an emery wheel 18, and induction coil 15 produces inducing current and makes warning circuit work, sends alarm sound.As the robber car is inverted, is made the vibrating sensing failure mechanisms, heavily cutting or polish jade with an emery wheel 18 will contact with conduction contact block 21 automatically, and promptly K1 closes, and still can make warning circuit work, sends alarm sound.
