Description
The utility model relates to a kind of door lock that is mainly used in anti-stealing safety, belongs to alarming lock for building field.
At present, the existing alarming lock that is used on the door is of a great variety, has mechanical, photo-electric or magnetic inductive, mechanical is the signal conversion part that machinery is installed in lock, this signal is delivered to outside warning device, though this lock can be reported to the police, but volume is big, is easy to generate malfunction; And the alarming lock of photoelectricity or magnetic inductive, though volume is little, the accuracy height, the cost height generally is not suitable for family and uses.
The purpose of this utility model is a kind of alarming lock of design, and volume is little, and is rational in infrastructure, can connect alarm under special circumstances, sends alarm signal.
The designed a kind of alarming lock of the utility model mainly is made of lock body, locking bolt and snap close, locking bolt is positioned at lock body, one portable plate is installed on the supporting seat in the snap close, portable plate is fixed with the spring that is positioned at snap close, the supporting seat end is fixed with switch, switch is corresponding with the portable plate end, and switch is connected by the warning device of lead with the outside.
In the designed a kind of alarming lock of the utility model, spring is fixed by bolt, nut and snap close.The designed a kind of alarming lock of the utility model uses similarly to common lock in application process, and lock body is installed on the door, snap close is installed on the doorframe, the same with existing door lock in the ordinary course of things, door lock can be lived, the switch that is used to connect alarm in the lock is in off-state; And when door was prized by external force, the compression of locking bolt pressuring spring made portable plate end contact-making switch at this moment and the fixing portable plate generation displacement of spring, with switch closure, connected the external alert device.
The advantage of a kind of alarming lock that the utility model is designed is:
1. simple in structure, volume is little, is suitable for family and uses;
2. adopt the mechanical transmission structure of length of spring compressed formula, vibrations generally speaking or collision all can not produce
Malfunction, good reliability during use.
3. should not have any parts that produce signal or signal conversion in the lock, and only be provided with one and be equivalent to power switch one
The structure of sample, so cost is low, easy to use.
The designed a kind of alarming lock of the utility model mainly is applicable to family and office etc., also can be used for other field.
Fig. 1 is the structural representation of the designed a kind of alarming lock of the utility model.
