The device is composed of a spacer pin, the switch of an alarm, an inclined plane lock tongue, an auxiliary tongue and the alarm. When the door lock is normally unlocked and locked, the switch of the alarm is turned off, which does not consume electricity. When the door lock is unlocked in an abnormal mode, the switch of the alarm switches on the power supply of the alarm, and the alarm can give an alarm. The utility model has the advantages of simple structure, low cost and safety. The utility model is suitable for families, offices and each key department.
Description
The utility model is a kind of door lock unnormal unlocking warning device, can implement to report to the police when door lock is opened by various improper means.
Known various door lock warning devices can only prevent that all door lock from being hit or being prized at present, the robber is opened door lock with the mode of sawed-off dead bolt can not implement to report to the police.And all to belong to be exactly not report to the police, and also will consume electric power.
CN2101288U (being announced on April 8th, 1992) discloses a kind of " door lock warning device ", and this installs by door lock, alarm, and gauge tap and contact mechanism are formed.Contact mechanism is by screw rod, and double-contact lever, movable contact, single contact lever, spring are formed the conducting that utilizes the principle of screw rod and lever in the theory of mechanics to form the contact and disconnected the alarm and protection effect that reaches when lock and door directly destroyed.Though this device is more simple in structure than existing various warning devices, this device is obviously the same with other warning device, can not take to saw the robber and implement to report to the police when dead bolt is opened door.
The purpose of this utility model is to provide a kind of can both enforcement when door lock is opened by various improper modes to report to the police, and does not consume the device of electric power at ordinary times.To stop the generation of thievery.
The utility model is achieved in that a kind of door lock unnormal unlocking warning device, by comprising that spacer pin, alarm buzzer switch, inclined-plane dead bolt, labella and alarm buzzer form, it is characterized in that: described spacer pin and alarm buzzer switch are on the supporting seat that is listed between inclined-plane dead bolt and the labella.Spacer pin is along with closing with the inclined-plane that normally is open at labella spacing hole and inclined-plane dead bolt of door lock moves up and down; The alarm buzzer switch normally opens at door lock, blocked by labella when closing and be in closed condition.
Advantage of the present utility model is: in case door lock is closed, must open door lock with normal method, the alarm buzzer switch just is in closed condition.Simultaneously, because the alarm buzzer switch is in closed condition all the time when the normal open and close of door lock, so do not consume electric power usually.
The accompanying drawing drawing is described as follows:
Fig. 1 is structure of the present utility model and fundamental diagram.
Fig. 2 is a circuit diagram of the present utility model.
Each label declaration is as follows among the figure:
1-inclined-plane dead bolt 2-metope 3-supporting seat 4-alarm buzzer switch
5-switch dome spring 6-labella 7-labella spacing hole 8-spacer pin
Spring 10-labella top, 9-spacer pin top spring 11-alarm buzzer
Narrate the utility model embodiment in conjunction with the accompanying drawings:
Referring to Fig. 1 when closing door lock, inclined-plane dead bolt (1) moves forward and makes spacer pin (8) break away from the lower end, inclined-plane that labella spacing hole (7) moves to the inclined-plane dead bolt under the effect of spacer pin top spring (9), labella (6) contacts with metope (2) under labella top spring (10) effect, and alarm buzzer switch (4) is pushed down the maintenance closed condition by labella (6).The normal door lock of opening, inclined-plane dead bolt (1) moves backward earlier spacer pin (8) moved up along the inclined-plane of inclined-plane dead bolt (1) and enters in the labella spacing hole (7), labella (6) can not be moved, and alarm buzzer switch (4) is still pushed down by labella (6) and is in closed condition like this.Open door lock in case take improper mode, inclined-plane dead bolt (1) just can not playback, spacer pin (8) just can not on move, labella (6) will move forward under labella top spring (10) effect, when labella spacing hole (7) moves to alarm buzzer switch (4) when locating, switch dome spring (5) effect down alarm buzzer switch (4) will connect alarm buzzer (11) power supply and implement warning.
Can find out that referring to Fig. 2 the alarm buzzer switch also is meant this device power supply, the alarm buzzer switch is in closed condition, is meant that promptly this device power supply is in closed condition.
Can find out that referring to the foregoing description the utility model compared with prior art has following advantage: the just not power consumption of not reporting to the police; Adopt various improper means to open door locks and can both send warning, and simple in structure, cost is low, safe and reliable.Be applicable to family, office and each key departments.
