Abstract
The utility model relates to a burglar alarm for house doors, which primarily solves the problems that a burglar enters a house for stealing; a differential switch is arranged at one side of the house door or a door frame at the combination position of the house door and the door frame; an elastic sheet on the switch is positioned at the combination position of the house door and the door frame; the differential switch, a bell, a power plug, etc. form an alarm circuit. When the house door is closed, the elastic sheet on the switch is pressed and thus the alarm circuit is cut off. When the burglar opens the house door, the elastic sheet on the switch flies open so that the alarm circuit is switched on (the power plug is inserted in advance); at the moment, the bell vibrates and an alarm lamp lights so that the burglar is scared off.
Description
Technical field
The utility model relates to warning device, particularly a kind of burglar alarm of being located on the door.
Background technology
At present, the phenomenon in some local burglar's burglary is very serious.The people's normal life and work have been influenced.But do not find effectively to control the warning device of burglar's burglary as yet.
Summary of the invention
The purpose of this utility model is to provide a kind of simple in structure, easy to use, the warning device that can effectively control burglar's burglary.
In order to realize the purpose of this utility model, intend taking following technical scheme:
Door or doorframe one side in door and doorframe junction are provided with a differential switch 1, and the shell fragment 2 on the switch is in the two junction; Differential switch 1 constitutes warning circuit with alarm bell 3, attaching plug 4 etc.
Also be parallel with warning lamp 5 on the above-mentioned warning circuit.
Also be provided with K switch 6 on the above-mentioned warning circuit.
Above-mentioned differential switch 1 can with one be located at behind the door or the support 7 of doorframe other (containing body of wall) joins, support 7 and being connected of door or doorframe are to be the connection that the rotatable and drive differential switch in the center of circle is done displacement with fulcrum 8.
Advantage of the present utility model is simple in structure, and is easy to use, and the tinkle of bells during warning and light can startle household and neighbours, can effectively control and draw back with fear the burglar.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Embodiment
The disclosed structure of accompanying drawing is an embodiment of the present utility model.Among the figure, 1 is commercially available differential switch; 2 is the shell fragment on the differential switch, can be communicated with or disconnect warning circuit by it; 3 is alarm bell; 4 is attaching plug; 5 is warning lamp; 6 are set switch (can omit) in the warning circuit; 7 is support, and rotatable and drive differential switch 1 displacement (as to the C rotation) by fulcrum G8 is in order to avoid shell fragment 2 is in pressured state without warning device the time; 8 is support 7 and the set fulcrum G in placement, can be rotatable mechanisms such as screw, rivet; The A-----A line is the junction of door and doorframe.The utility model in use, can be with support 7 to D to rotation, drive differential switch 1 to B to displacement, be in position among the figure, this moment, shell fragment 2 made E, the F point in the circuit be in on-state, but because of plug-in source not, entire circuit still can not be worked.When door closed, shell fragment 2 was crushed on the door and the junction of frame, made the disconnection of E, F point, although plug in 4 with close a switch 6, circuit still is in off-state and can not works.When the moment that the burglar opens door, the shell fragment 2 on the differential switch is connected the warning circuit that E, F point is communicated with because of flicking, the alarm bell sound that shakes, and warning lamp is light, thereby startles household and neighbours, draws back the burglar with fear.
