Abstract
The utility model discloses a theft-prevention alarm lock, which relates to theft-prevention alarm technology. The utility model is composed of a casing, a square tongue plate, an inclined tongue, a spring, a lock catch box, a circuit board, a switch, a loudspeaker and a battery box which are connected with each other. The utility model combines the advantages of a common door lock and a theft-prevention alarm, constitutes an AND gate logic state by utilizing two travel switches in the lock in order to control the on-off state of an alarm circuit so as to achieve the goal of alarm control by utilizing the mechanisms in the locks and the on-off state of the door. The utility model solves the problems of frequent switch transfer and rapid battery loss, which exist in other theft-prevention alarms, and has the advantages of simple structure, convenient operation, less power consumption and accurate alarm.
Description
The utility model relates to a kind of burglar alarm technology, especially anti-theft alarm lock.
At present, known door lock is not pacified alarm, and door is in case pried open by the thief, and lock has just lost effect, though known burglar alarm can be reported to the police, in use, needs frequent changeover switch, and is cumbersome, power consumption is fast, and easy wrong report the by mistake.
The purpose of this utility model provides a kind of novel anti-theft alarming lock, it combines the advantage of common door lock and burglar alarm, utilize two travel switches in the lock, form and the gate logic state, the disconnection or the conducting of control warning circuit reach and utilize the on off state of interior mechanism of lock and door to control the purpose of reporting to the police.Overcome that original door lock is not reported to the police, the frequent changeover switch of alarm, power consumption are fast, the easy shortcoming of wrong report.
The purpose of this utility model is to realize like this, it is to be formed by connecting by shell, square hyoplastron, oblique tongue, spring, keeper, circuit board, switch, loudspeaker, battery case, tiltedly tongue is entangled by spring, and control its scope of activities by spring, travel switch K1 is installed in the back of square hyoplastron in the lock box, by square hyoplastron control, compress or the side's of unclamping hyoplastron makes switch k1 conducting and disconnection, travel switch K2 is installed in the shell front, by keeper control, be used for reflecting the state of an open and close, at closing time the keeper clamping switch, when opening the door, switch unclamps; Two switches all use constant close contact, and the series connection of two switches; Circuit board is linked to each other by electric wire with Yang Shengqi, battery case, travel switch K1, K2; Keeper is provided with square bolt hole, inclined tongue hole, pilot hole, supporting use when installing and using.
When work, utilize two travel switches to form and the gate logic state, make circuit disconnect conducting, door is shut, and when not locking, travel switch K1 is owing to the extruding of square hyoplastron, and constant close contact disconnects, and K switch 2 is because keeper pushes, and constant close contact disconnects, and circuit is obstructed.
When door was opened, travel switch K2 was owing to leave keeper, and constant close contact closure, K switch 1 still disconnect, and circuit is still obstructed.
Door is in the open and close and the process of locking, at first travel switch K2 is because the restriction of keeper, constant close contact becomes disconnection by closure, travel switch K1 is because square hyoplastron is overhanging mobile, leave travel switch K1, make the constant close contact closure of travel switch K1, because K switch 2 disconnects, K switch 1 closure, circuit is still obstructed.
When turning the key in the lock, the side's of making hyoplastron retraction, square hyoplastron is clamping switch K1 again, makes the contact commonly used of K switch 1 become disconnection by closure, and when opening the door, travel switch K2 leaves keeper, because K switch 1 disconnects, circuit is still obstructed.
The various states that more than are open and close in the normal use of anti-theft alarm lock, lock.In normal use, owing to having at least a travel switch to be in disconnected all the time or opening state, circuit is always obstructed, alarming lock does not always ring, when the thief forces open the door, because door is locked, side's tongue is overhanging, travel switch K2 constant close contact closure, when door was pried open, keeper left travel switch K1, make the constant close contact closure of travel switch K1, because travel switch K1, K2 are closed simultaneously, circuit turn-on, alarming lock begin to report to the police.
Since adopt such scheme, simple in structure, easy to use, little power consumption, it is accurate to report to the police.
