Abstract

The utility model discloses an electromagnetic door lock, comprising a door leaf and a doorframe. The door leaf and the doorframe are provided with a gag bit and an electromagnet which are in mutually corresponding, and the electromagnet is provided with a hall detecting element and an attracting indicating device. A door can be locked by utilizing suction force of the electromagnet at the time of switching power; when the door is opened at the time of switching off power, the utility model has the advantages of simple structure, convenience and practicality as well as reliable performance.

Description

Electromagnetic door lock

The utility model relates to a kind of door lock.

In the prior art, along with the raising day by day of living standard and the progressively enhancing of antitheft idea, people are also more and more higher to the requirement of door lock, at first door lock will have anti-theft feature, switch uses and will make things convenient for then, so has also occurred the door lock of numerous species on the market, but most door locks is still based on frame for movement, not only complex structure, and functional performance is also relatively poor.Also bring into use a kind of electronic anti-theft door in recent years in some New Residential Quarters and residential quarters, this security door mainly uses the doorway at unit building, and it also exists complex structure, poor reliability, the easy shortcoming of damaging.

The purpose of this utility model is: a kind of electromagnetic door lock is provided, and this door lock is installed in electromagnet on the doorframe, and armature is installed on the door leaf, the suction of electromagnet is with on the door lock when utilizing energising, open the door during outage, not only simple in structure, and convenient and practical, dependable performance.

The technical solution of the utility model is: a kind of electromagnetic door lock, comprise door leaf and doorframe, and the armature and the electromagnet of mutual correspondence is installed on described door leaf and the doorframe.

The further technical scheme of the utility model is: a kind of electromagnetic door lock, comprise door leaf and doorframe, and the armature and the electromagnet of mutual correspondence is installed on described door leaf and the doorframe; Described electromagnet is provided with hall detection component and adhesive indicating device.

The utility model has the advantages that:

1. the utility model frame for movement is simple, and the magnetic force when utilizing electromagnet energising and outage comes adhesive armature, thereby carries out switch as the door lock opposite house.

2. the utility model is very easy to use, and the energising of electromagnet and outage can have various ways to select for the user, for example key, IC-card, press button etc.

The utility model will be further described below in conjunction with drawings and Examples:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is circuit theory diagrams of the present utility model;

Wherein: 1 door leaf; 2 doorframes; 3 armature; 4 electromagnet; 5 hall detection components; 6 adhesive indicating devices.

Embodiment: as shown in Figure 1, a kind of electromagnetic door lock comprises door leaf [1] and doorframe [2], and the armature [3] and the electromagnet [4] of mutual correspondence is installed on described door leaf [1] and the doorframe [2]; Described electromagnet [4] is provided with hall detection component [5] and adhesive indicating device [6].

As shown in Figure 2, M1, M2 are two windings on the same iron core; 8V is that output voltage is the three end power supplys of 8V; RV1, RV2 discharge the piezo-resistance of inductance back-pressure when being the 24V power supply; HL closes the Hall element of state for detecting magnetic circuit group; CON is a connector, and 1,2 pin are the magnet control end, power up, and electromagnet is energized, cut electricity, electromagnet discharges, and 3,4,5 pin are one group of passive feedback contact, when electromagnet is energized, and the magnetic circuit closure, original 4,5 normally closed changes are often opened, and 3,4 changes of originally often opening are normally closed; L1 is a double color luminotron, is used for the indication of magnetic circuit closure state, the closed glow of magnetic circuit, on the contrary green bright; 1,2,3,4 is the wire jumper end among the figure, 2,3 short circuits among the figure when 24V powers, 1,2 and 3,4 difference short circuits during the 12V power supply; IC and R1, R2, C2, W1 are delay circuit, power on after the time-delay of a period of time, and electromagnet just is energized, and regulate W1 and can change delay time, and numerical value does not wait from zero by hundreds of seconds; Response time after the electromagnet outage is substantially equal to the release response time of relay R EL1; REL1 and C1 are degaussing circuit among the figure, and after the circuit dead electricity, electromagnetic coil is through REL1 and C1 reverse parallel connection, and oscillatory extinction electric current therebetween plays demagnetizing action, thereby make the iron core needn't be with real soft magnetic materials manufacturing.

Claims

1. an electromagnetic door lock comprises door leaf [1] and doorframe [2], it is characterized in that: armature [3] and electromagnet [4] that mutual correspondence is installed on described door leaf [1] and the doorframe [2].

2. electromagnetic door lock according to claim 1 is characterized in that: described electromagnet [4] is provided with hall detection component [5] and adhesive indicating device [6].
