The utility model has the advantages of simple and reasonable structure, simple to operate, the stable performance can effectively prevent to steal.
Description
The utility model relates to the technology, particularly security door of door.
People steal in order to prevent, reinforce security door, but force open the door by force and the phenomenon stolen also happens occasionally, and especially at night, owner is sleeping darker, and the sound of forcing open the door of little sound can't be reminded.
The purpose of this utility model is to people design a kind of security door, when door sends warning during by unnormal unlocking, to remind owner.
The utility model comprises doorframe, door-plate, with key operated lock, it is characterized in that on door-plate fixedly warning circuit, establish two normally closed switch K on the circuit
1, K
2, normally closed switch K
1Rely on the keeper inboard of lock, normally closed switch K
2Rely on slide block one end, slide block is arranged on the door-plate side that connects hinge.
Normally at closing time, door is shut by lock, and keeper gos deep into doorframe, makes normally closed switch K
1Place closure state, and be butted on the slide block force switch K of door-plate by the doorframe of opposite side
2Disconnect, alarm circuit is cut off.During normal door, lock withdraws from keeper from doorframe, forces normally closed switch K
1Disconnect, alarm circuit is cut off.When door during by unnormal unlocking, keeper can't force K switch
1Disconnect, but be in closure state, door is opened, and slide block withdraws from door-plate, normally closed switch K
2Be in closure state, alarm circuit forms, and promptly reports to the police.
The utility model is simple and reasonable for structure, and is easy for installation, and stable performance can effectively prevent to steal.
Now in conjunction with the accompanying drawings, further specify.
Accompanying drawing is the utility model structural representation.
Among the figure, 1 doorframe, 2 door-plates, 3 slide blocks, 4 K switch
2, 5 dc sources, 6 warning acoustical generators, 7 locks, 8 keepers, 9 K switch
1
On door-plate 2, be connected in series warning acoustical generator 6, dc source 5, normally closed switch K with lead
19, normally closed switch K
24.
With normally closed switch K
19 contact at the inner of keeper 8.Offer the hole in door-plate 2 one sides that hinge is set, to cooperate slide block 3, normally closed switch K
24 contact at the inner of slide block 3.
Above-mentioned K switch
2Can be made into one with slide block, the outer end is an electrical insulator, and the inner is a conductive material.
