Background technique
With the development of building equipment and automation control, more and more simple automatically controlled magnetic key operated locks have obtained widely answering
With.But working principle of the similar product in the market in terms of feedback of alarming substantially only using door it is not closed as alarm trigger,
Although such design can lead to door to door body mechanical breakdown that may be present, power loss or control failure, artificial limitation factor etc.
The case where body cannot be closed carries out alarm feedback.But due to realizing that its locking function is realized by electromagnetic attraction, thus
Its suction is limited, so theoretically door body can also be made to unlock by enough pulling force, in this way if being unable to normal release
In the case of there is and can not hale door body (rather than use feeling answer card or password normal door special circumstances) to someone's malice
Alarm feedback is carried out, therefore is had a greatly reduced quality on such product anti-theft function.
Utility model content
The purpose of the utility model is to provide a kind of simple door closure burglar alarm electric-controlled type magnetic key operated locks, to solve electricity
The problem of room magnetic key operated lock is controlled in the case where artificially maliciously haling door body, alarm feedback can not be carried out to it.
In order to achieve the above object, the utility model is the technical scheme adopted is that a kind of simple door closure uses anti-theft journal
Alert electric-controlled type magnetic key operated lock, including electromagnetic lock and safety door switch, the electromagnetic lock are feedback electromagnetic lock, and electromagnetic lock includes that magnetization is inhaled
Attached side, the safety door switch are electrically connected with the signal feedback end of electromagnetic lock, which is characterized in that further include power-supplying circuit and
Feedback control circuit；The power-supplying circuit include power supply, the two poles of the earth of the power supply pass through respectively a control terminal A with it is described
Magnetization absorption side electrical connection；The feedback control circuit includes relay, and the coil of the relay accesses two controls
It holds between A and magnetization absorption side, the normally opened contact of the relay is patrolled by control terminal B with the negative of the safety door switch
Signal end concatenation is collected, the signal feedback end is also connected with alarm.
The technical solution of the utility model also has the following characteristics that
The power supply is 12V DC power supply.
The relay is JR series relay.
The model D4SL-N or D4NL of the safety door switch.
The alarm is active or passive alarm.
The control terminal A and control terminal B is solenoid valve.
The beneficial effects of the utility model are: a kind of simple door closure burglar alarm electric-controlled type magnetic force of the utility model
Lock, structure is simple, and design rationally, can hale door body to someone's malice rather than use feeling answers the special of card or password normal door
Situation carries out alarm feedback.

Specific embodiment
The technical solution of the utility model is described in further detail below in conjunction with Detailed description of the invention and specific embodiment.
As shown in Figure 1, a kind of simple door closure burglar alarm electric-controlled type magnetic key operated lock of the utility model, main includes peace
Air cock switch 6, electromagnetic lock, power-supplying circuit and feedback control circuit.
Safety door switch 6 is a kind of door switch applied to security applications, mainly for detection of the switch of door opening and closing, safety
Door switch cocoa effectively prevents the generation of accident.
Electromagnetic lock be feedback electromagnetic lock, such electromagnetic lock band feedback function, i.e., lock the inside with feedback signal and it is normally opened often
Signal is closed, can be matched with alarm system, such electromagnetic lock also has the multiple functions such as delay, feedback.
Such electromagnetic lock includes magnetization absorption side 5 and signal feedback end 7, wherein the signal feedback end 7 of electromagnetic lock and safety
Door switch 6 is electrically connected.
As shown in Figure 1, a kind of simple door closure of the utility model power supply control of burglar alarm electric-controlled type magnetic key operated lock
Circuit includes power supply 2, and the two poles of the earth of the power supply 2 pass through a control terminal A3 respectively and are electrically connected with magnetization absorption side 5.
As shown in Fig. 2, a kind of simple door closure of the utility model feedback control of burglar alarm electric-controlled type magnetic key operated lock
Circuit includes a relay 4, and the coil of the relay 4 accesses between two control terminal A3 and magnetization absorption side 5, relay 4
Normally opened contact concatenated with the negative logic signal end of then safety door switch 3, signal feedback end 7 is also connected with alarm.
A kind of power supply 2 of simple door closure burglar alarm electric-controlled type magnetic key operated lock of the utility model is preferably 12V DC
Power supply.
A kind of relay 4 of simple door closure burglar alarm electric-controlled type magnetic key operated lock of the utility model is preferably JR series
Relay.
A kind of model of the safety door switch 3 of the simple door closure burglar alarm electric-controlled type magnetic key operated lock of the utility model
D4SL-N or D4NL, is exclusively used in electromagnetic lock,
A kind of alarm preferably active or nothing of the simple door closure burglar alarm electric-controlled type magnetic key operated lock of the utility model
