Description

Anti-theft alarm lock

The utility model relates to a kind of burglar alarm lock, the anti-theft alarm lock of usefulness such as particularly a kind of motorcycle, bicycle, tricycle.

The lock that is used for motorcycle and bicycle in the market roughly is divided three classes, and a class is the ring lock made from iron chains or wirerope, car can be tied up on the fixed objects such as trees, electric pole, in case car is stolen, its shortcoming is to use inconvenience; Another kind of lock is to be fixedly mounted on the car body, utilizes the lock thick stick to block wheel, then is difficult for defence but directly car is moved or pull away with car for the robber; The 3rd class then is the product of commercially available " motorcycle anti-theft alarm ", though its anti-theft alarm result is better, but because its power supply, parts partial installations such as news Chinese percussion instrument, have outside the many places lead is exposed to, destroyed easily, and price is higher, the another kind of this series products is used for the electronic product " bicycle anti-theft alarm device " of bicycle, it is a power switch of controlling alarm with a key that carries, when vibrations take place in bicycle, can sound the alarm reminding the bicycle user, but because after the user bought alarm, also must be equipped with lock, not only troublesome poeration but also uneconomical.

The purpose of this utility model is to provide a kind of anti-theft alarm lock, and it can be locked car and can report to the police again, and easy and simple to handle, low price; In order to make warning more accurate, safe and reliable in addition, design a kind of vibrating sensor especially.

Implementation of the present utility model is as follows: this alarming lock includes lock body and parallel bars fork, end at lock body is fitted with shell, skeleton is installed in the shell, the circuit board and the buzzer that battery are installed on the skeleton and form by time-delay control vibration alarming loop, the vibration alarming loop apparatus is installed on lock body or shell, in the lock car hole in lock body the shell fragment seat is installed, two shell fragments are housed on the shell fragment seat to be connected on respectively in the control loop of alarm, when being in lock car state, the lock thick stick touches mutually with each shell fragment battery and alarm circuit is connected, and when being in unlocking condition, shell fragment disconnects, circuit disconnects, and alarm is in off working state; In addition, in the design of this utility model, in order to prevent that the robber from dismantling the battery of alarm in the lock, designed the battery cover that has lock hole especially, when being in lock car state, the hook on the battery cover is locked thick stick and is pinned, and can't open, only when unlocking condition, could change the battery in the alarm.Make power switch the situation of electric leakage occur in order to prevent rainwater from bleeding lock body, the utility model adopts vibrating sensor, this vibrating sensor links to each other with two other shell fragment on the shell fragment seat, when being in lock car state, the lock thick stick does not contact with each shell fragment, the vibrating sensor operate as normal, when being in unlocking condition, the lock thick stick contacts vibrating sensor short circuit and no-output with each shell fragment, like this when the etch owing to rainwater makes that electric leakage appears in power switch, vibrating sensor still cuts out, and circuit is in static state, thereby has reduced leaky, the vibrating sensor of the utility model design is by metal bar, plastic pipe and plug constitute, and metal bar and plug are the electric conductivity good metal, and the outside of plug is a plane and inside is a depression, plug and plastics involution can constitute cavity, metal bar then is movably placed in this cavity, and its two ends can contact with plug is movable, when shaking, because the rolling of metal bar or beat can make the sensor two ends disconnection of moment occur.

The utility model unites two into one owing to locking with alarm, and this has counted special battery cover and vibrating sensor, not only can overcome the leaky that power switch is produced owing to the rainwater influence, and make others can not arbitrarily take down the battery in the lock body, and it is rational in infrastructure, make easily, solved the burglar alarm problem of motorcycle, bicycle, tricycle etc. preferably.

Below in conjunction with accompanying drawing embodiment of the present utility model is further described

Among Fig. 1, Fig. 2, Fig. 3,1. shell, 2. battery cover, 3. skeleton, 4. battery, 5. shell fragment seat, 6.A, the power switch shell fragment, B, short circuit sensor shell fragment, 7. parallel bars forks, 8. lock body, 9. lock car hole, 10. buzzer, 11. circuit boards, 12. putting holes, 13. phonate holes, 14. cars fork.

Referring to Fig. 1, Fig. 2, Fig. 3, the utility model comprises lock body 8 and parallel bars fork 7, be fitted with shell 1 in the outside of lock body 8, be provided with skeleton 3 in the shell 1, the circuit board 11 and the buzzer 10 that battery 4 are installed on the skeleton 3 and form by time-delay control vibration alarming loop, shell fragment seat 5 is installed on the lock body 8, on the shell fragment seat 5 power supply is installed, switch shrapnel 6A and short circuit sensor shell fragment 6B, shell fragment 6A is connected between the positive pole of battery 4 and the circuit board 11 as power switch, an other utmost point of circuit board 11 connects the negative pole of battery 4, and shell fragment 6B is connected in parallel on the vibrating sensor two ends on the circuit board, and warning sounding component buzzer 10 is connected with alarm circuit.When car is not locked, parallel bars fork 7 inserts in the putting hole 12, power switch shell fragment 6A disconnects, the circuit access failure, and vibrating sensor short circuit this moment shell fragment 6B is switched on, because when weather rains, power switch shell fragment 6A might leak electricity and vibration by bike time the etc. excites warning because of rainwater drenches, and its power consumption meeting makes current drain bigger, makes sensor two terminal shortcircuits by short circuit shell fragment 6B, circuit just only may be operated in static state, thereby can significantly reduce electric leakage; When being in lock car state, parallel bars fork 7 inserts in the lock car hole 9, and power switch shell fragment 6A connects, and vibrating sensor short circuit shell fragment 6B disconnects, and alarm promptly enters work, if car is rocked, lock promptly can send chimes of doom.Phonate hole 13 opening directions can only leave small space between the two in the face of car fork 14, may with what prevent to destroy buzzer 10 in the phonate hole 13 and " blocking phonate hole ".

Among Fig. 4,15. lock holes, 16. fixing screw threads.Battery cover in the utility model is provided with lock hole 15, but pincers is enclosed within the shell 1, after lock is good, parallel bars fork 7 has also passed the lock hole 15 on the battery cover, like this when inserting lock car hole 9, as long as lock is not opened, even the screw that screws off on the fixing screw thread 16 also can't be opened battery cover and take out battery, only when lock is opened, could take out battery cover.This battery cover one end has closure plate to seal battery, and the front portion of the one side vertical with closure plate is provided with lock hole 15.

Among Fig. 5,17. metal bars, 18. plastic pipes, 19. plugs.Metal bar 17 and plug 19 are the electric conductivity good metal, plug 19 can constitute a cavity with plastic pipe 18 involutions, metal bar 17 places this cavity, two ends can contact with plug 19 activities, when shaking, since the rolling of metal bar 17 or beat, and make the sensor two ends disconnection of moment occur, and then can conclude that vibration has taken place car body.
