Abstract
The utility model discloses an automatic and anti-theft acoustic-optic language warning apparatus for seeking helps, which comprises a power source, an acoustic-optic language warning apparatus, a relay and an electronic switch, wherein, the electronic switch is used for controlling to open and close the relay. The electronic switch is connected with a lock switch and a door switch which are mutually connected in parallel, the lock switch is arranged on a door lock, the door switch is arranged between a door and a doorframe, and the lock switch and the door switch are always in a state that one is cut off and the other is switched on. The utility model can send out acoustic-optic and language alarms when a thief prizes the door, and has no influence for the normal opening of households.
Description
The utility model relates to a kind of burglar alarm.
At present, along with improving constantly of living standards of the people, the theft crime case constantly increases, stealing case according to investigations in a large number is to force open the door, the a large amount of two-earners family of China particularly, daytime nobody home, and if general family when not finding that the thief forces open the door evening, have an opportunity to take advantage of to the robber equally, thereby the people's lives and property is sustained a great loss.
The purpose of this utility model is: a kind of antitheft acousto-optic language apparatus for ask for help through of reporting to the police automatically is provided, and it can send acousto-optic and language alarm when the burglar forces open the door, and does not influence the normal unlatching of resident family.
The technical solution of the utility model is: a kind of antitheft acousto-optic language apparatus for ask for help through of reporting to the police automatically, this device comprises the electronic switch of power supply, acousto-optic language alarm, relay and pilot relay adhesive, be connected with the lock-switch and the door switch of mutual parallel connection on the electronic switch, lock-switch is installed on the door lock, door switch is installed between door and the doorframe, and lock-switch and door switch are in one disconnected one logical state all the time.
The further technical scheme of the utility model is: a kind of antitheft acousto-optic language apparatus for ask for help through of reporting to the police automatically, this device comprises the electronic switch of power supply, acousto-optic language alarm, relay and pilot relay adhesive, be connected with the lock-switch and the door switch of mutual parallel connection on the electronic switch, lock-switch is installed on the door lock, door switch is installed between door and the doorframe, and lock-switch and door switch are in one disconnected one logical state all the time; Described electronic switch is connected to form by two triodes, and two collectors wherein are connected to each other, and an emitter is connected on another base stage: when door by and when closing, lock-switch is in off-state, door switch is in conducting state.
Principle of work of the present utility model is, by parallel connection, be in one disconnected one logical lock-switch and door switch all the time and control electronic switch, come pilot relay by electronic switch, control the acousto-optic language alarm, when lock-switch and door switch are in one disconnected one logical or two when logical by relay, must not on the relay, and can not send warning, when lock-switch and door switch are in two disconnected states, trigger electronic switch, it is electric that relay is got, and the acousto-optic language alarm sends warning.
The utility model has the advantages that:
1. the utility model is controlled whole device by mutual parallel connection and the lock-switch and the door switch that are in one disconnected one logical state all the time, when the burglar forces open the door, door lock is not opened, so lock-switch still is in off-state, door switch then disconnects because of door is unlocked, at this moment, lock-switch and door switch are in two disconnected states, trigger the electronic switch conducting, it is electric that relay is got, and the acousto-optic language alarm sends warning.
2. the utility model does not influence the user and normally uses, and when the user opens door with normal mode, make the lock-switch conducting, and door switch disconnects, and lock-switch and door switch still are in one disconnected one and lead to state, therefore, can not cause the acousto-optic language alarm.
The utility model will be further described below in conjunction with drawings and Examples:
Fig. 1 is a circuit block diagram of the present utility model;
Figure is a circuit diagram of the present utility model;
Wherein: 1. acoustic-optic alarm; 2. relay; 3. electronic switch; 4. lock-switch; 5. door switch; 6. power supply; 7. triode.
Embodiment: a kind of antitheft acousto-optic language apparatus for ask for help through of reporting to the police automatically, this device comprises the electronic switch [3] of power supply [6], acousto-optic language alarm [1], relay [2] and pilot relay [2] adhesive, be connected with the lock-switch [4] and the door switch [5] of mutual parallel connection on the electronic switch [3], lock-switch [4] is installed on the door lock, door switch is installed between door and the doorframe, and lock-switch and door switch are in one disconnected one logical state all the time; Described electronic switch [3] is connected to form by two triodes [7], and two collectors wherein are connected to each other, and an emitter is connected on another base stage; When door was closed, lock-switch [4] was in off-state, and door switch [5] is in conducting state.Principle of work of the present utility model is, by parallel connection, be in one disconnected one logical lock-switch [4] and door switch [5] all the time and control electronic switch [3], come pilot relay [2] by electronic switch [3], control acousto-optic language alarm [1] by relay [2], when lock-switch [4] and door switch [5] are in one disconnected one logical or two when logical, must not on the relay [2], and can not send warning, when lock-switch [4] and door switch [5] are in two disconnected states, trigger electronic switch [3], it is electric that relay [2] is got, and acousto-optic language alarm [1] sends warning.The utility model is controlled whole device by mutual parallel connection and the lock-switch [4] that is in one disconnected one logical state all the time with door switch [5], when the burglar forces open the door, door lock is not opened, so lock-switch [4] still is in off-state, door switch [5] then disconnects because of door is unlocked, at this moment, lock-switch [4] is in two disconnected states with door switch [5], trigger electronic switch [3] conducting, it is electric that relay [2] is got, and acousto-optic language alarm [1] sends warning; The utility model does not influence the user normally to be used, and when the user opens door with normal mode, make lock-switch [4] conducting, and door switch [5] disconnects, and lock-switch [4] still is in one disconnected one logical state with door switch [5], therefore, can not cause acousto-optic language alarm [1].
