Abstract
The utility model relates to a magnetic door lock, particularly an improved safety magnetic door lock which can early pre-warn and automatic alarm when an external force invades. When the external force invades, the magnetic door lock has the functions of early precaution and automatic alarm. The magnetic door lock comprises an electromagnetic lock head and a relay iron plate, wherein the electromagnetic lock head is composed of an electromagnet provided with a coil and an outer shell. The utility model is characterized in that at least two pairs of through holes and blind holes provided with thread are respectively arranged at the corresponding positions of the outer shell and the electromagnet, and a screw rod is connected with the blind holes in a screwing mode after passing through the through holes. An elastic medium is arranged at the part out of the outer shell of the screw rod, the rear part of the electromagnet is provided with a triggering device and a triggering handle of the triggering device is supported at the bottom of the outer shell. The utility model has the advantages that when an external force invades, if the acting force of the external force overcomes the resistance force of the elastic medium, a microswitch is triggered, and a short-distance alarm device is started. If the external force invades continuously, a remote alarm device is started after the short-distance alarm delays with a preset time.
Description
Technical field
The utility model relates to a kind of magnetic door lock, especially relates to a kind ofly having when invading at external force, can early warning and the improved safe magnetic door lock of reporting to the police automatically.
Technical background
Utility model patent ZL93225436.5 has disclosed a kind of safe magnetic door lock, and this magnetic door lock is made of Electromagnetic lock 1, continue iron plate 2 and sniffer 3, and described sniffer 3 is made of exploring electrode 31 and memory wafer circuit board 32.Described exploring electrode 31 is installed on the Electromagnetic lock 1, and with the position of iron plate 2 fitting faces that continue, described memory wafer circuit board 32 is installed in continue iron plate 2 and the one side that Electromagnetic lock 1 cooperates, be serially connected in two be detected a little between.31 1 of described exploring electrodes are connected another root ground connection with central controller.After door leaf was closed and connects power supply, the Electromagnetic lock 1 and the formation magnetic force loop between the iron plate 2 of continuing firmly attracted mutually.Simultaneously, exploring electrode 31 is switched on memory wafer circuit board 32, after central controller reads the sequence number of memory wafer circuit board 32, just can understand closing and opening of door exactly.If any the people iron plate of continuing of non-matching is placed on the fitting face of Electromagnetic lock 1, makes door leaf be in opening all the time, at this moment central controller is because of reading to send warning less than the sequence number of memory wafer circuit board 32.
The purpose of this utility model patent is in order to prevent after door leaf is by legal opening, and has people's (contain the stranger and inside is stood fast at from robber person) that the iron plate of continuing of non-matching is placed on the fitting face of Electromagnetic lock 1, and makes door leaf be in opening all the time.Yet the magnetic door lock of this utility model is with door leaf when closed, if there is the people to think that brute force swarms into, though door lock has 500 kilograms powerful magnetic force, is unlikely door is opened, and also can cause certain destruction to door leaf, and at this moment central control room known nothing.
Summary of the invention
The purpose of the utility model provides a kind of improved magnetic door lock, and this magnetic door lock has, when external force is invaded, and early warning and the function of reporting to the police automatically.
The utility model is achieved in that a kind of improved magnetic door lock, comprises the Electromagnetic lock 1 and the iron plate 2 of continuing, and described Electromagnetic lock 1 is made of the electromagnet 11 and the shell 12 of belt coil; It is characterized in that: the correspondence position of described shell 12 and electromagnet 11, at least be respectively equipped with two pairs of through holes 121 and threaded blind hole 111, screw rod 4 passes through hole 121 and is threaded with blind hole 111, part outside the shell 12 of screw rod 4 is provided with elastic fluid 5, the rear portion of described electromagnet is provided with flip flop equipment 6, and the shake-up handle 61 of described flip flop equipment 6 holds mutually with the bottom of shell 12.
Described flip flop equipment 6 is microswitches.
Described flip flop equipment 6 is magnetic switch elements, and described magnetic switch element can be a tongue tube, also can be Hall element.
Described Electromagnetic lock by installing plate and screw on doorframe; Fixedly connected between Electromagnetic lock 1 and the installing plate 91.
The described iron plate 2 of continuing is fixed on the door leaf by anti-drilling nut 921 and set bolt 922.
The utility model has the advantages that: when external force was swarmed into, if its active force has overcome the resistance of elastic fluid, microswitch was triggered, and then the short range warning device is activated.When continuing to invade, after the short range of one section preset time is reported to the police time-delay, then start remote alarming device as external force.
