CN2409321Y - Electronic alarm anti-theft door - Google Patents

Abstract

The utility model provides an electronic alarm theftproof door, and relates to the improvement of a theftproof door. The utility model is characterized in that after a plurality of button switches are connected in series, the button switches are connected with a power supply through a relay, a contact point of which is connected with the power supply through an alarm and the button switches are respectively linked with each door latch in a contact way. The utility model has the advantage that full closed circuits are used in the door which is locked, the power supply of the circuits is switched off as long as the door is damaged due to a mechanical attack and accordingly an alarm signal is sent.

Description

The electronic warning and anti-theft door

The utility model belongs to technical field of buildings, relates to a kind of improvement of security door.

At present, though the kind of metal anti-theft door is more, the function that has is also more complete; anti-theft effect is good, but general does not all have a warning function, belongs to a kind of passive theft-preventing protecting device; though the metal anti-theft door that has has warning function, the structure of this class security door is mostly comparatively complicated.

The purpose of this utility model provides a kind of electronic warning and anti-theft door simple in structure that has warning device.

The technical solution of the utility model is as follows:

Be connected with power supply by relay by several press button serial connection backs, the contact of relay is connected with power supply by alarm, and each press button touches interlock with each grafting respectively.

The utility model has the advantages that: this door adopts lock back complete closure circuit, destroys as long as be subjected to mechanical attack like this, and circuit will cut off the power supply, thus the alarm signal of sending.

Fig. 1 is a structure chart of the present utility model;

Fig. 2 is a circuit diagram of the present utility model;

Wherein: the 1st, door, the 2nd, doorframe, the 3rd, door insert, the 4th, and snap, JC are that relay, XF are that alarm, K are that press button, E are power supplys.

Door is not when having lock status, and lock is inserted not in doorframe, and slotting being in press button of lock separated shape Attitude, this moment, alarm was in closed condition, when door during at locking state, lock insert and the snap contact-making switch also Switch is all closed, and alarm is connected, and is disconnected if any any one switch, and alarm is namely directly reported Alert or pass through telephone call.

Claims (1)

1, a kind of electronic warning and anti-theft door, form by door (1), doorframe (2), door slotting (3), door lock spring (4), it is characterized in that: be connected with power supply E by relay J C by several button switch K serial connection backs, the contact of relay J C is connected with power supply E by alarm XF, and each button switch K is inserted (3) respectively and contacted interlock with each.
