The closed state of the door is judged by the infrared radiation from the infrared photoelectric sensor 18 to the door. When the infrared photoelectric sensor 18 detects that the door is in an open state, the electromagnetic block 19 is kept energized so that the lock tongue 4 continues to shrink inside the lock body 1. When the infrared photoelectric sensor 18 detects that the door is in a closed state, the power supply of the electromagnetic block 19 is terminated. At this time, the spring 16 will extend outward, thereby pushing the lock tongue 4 to move outward into the lock slot 3, thereby realizing self-locking of the door, thereby protecting the lock tongue 4 from external damage and affecting the service life of the magnetic lock.
[0026] In this embodiment, if Figure 1 - Figure 3 As shown, a slide rod 15 is fixedly connected to the inside of the spring 16 inside the lock body 1, and the connecting block 14 is slidably connected to the outside of the slide rod 15, thereby ensuring that the lock tongue 4 as a whole can move stably and quickly inward, while ensuring the overall contraction stability of the spring 16 during the squeezing process.
[0027] In this embodiment, if Figure 1 - Figure 3 As shown, a movable groove 12 is provided at the upper end of the fixed block 11, and a connecting block 10 is fixedly connected to one end of the lock tongue 4 close to the inside of the lock body 1. The connecting block 10 is slidably connected inside the movable groove 12. By moving the connecting block 10 inward, the lock tongue 4 can be manually driven to move inward, thereby achieving the opening of the magnetic lock.
[0028] In this embodiment, if Figure 1 - Figure 3 As shown, a disc 8 is rotatably connected inside the lock body 1, a gear 9 is fixedly connected to the outside of the disc 8, a tooth groove 13 is provided at the bottom of the connecting block 10, and the tooth groove 13 is meshingly connected to the gear 9, wherein the back of the connecting block 10 fits against the outer side of the disc 8 to ensure the stability of the connecting block 10 during movement, and the rotation of the gear 9 drives the tooth groove 13 to move in the rotation direction of the gear 9, thereby realizing the movement of the lock tongue 4.
[0029] In this embodiment, if Figure 1 - Figure 3As shown, a hand wheel 17 is rotatably provided on the outer side of the lock body 1. One end of the hand wheel 17 passes through the lock body 1 and is fixedly connected to the inside of the disc 8. By rotating the hand wheel 17, the gear 9 inside the lock body 1 is driven to rotate, so that the lock tongue 4 moves and contracts toward the inside of the lock body 1, thereby realizing manual opening of the electromagnetic lock.
[0030] In this embodiment, if Figure 1 - Figure 3 As shown, lock box mounting holes 5 are provided at the upper and lower ends of the lock box 2, a lock body mounting hole 6 is provided on the outer side of the lock body 1 near the inner corner, and a battery 7 is provided inside the lock body 1. The lock box 2 can be installed on the outside of the door frame through the lock box mounting hole 5, and the lock body mounting hole 6 can be used to install the lock body 1 on the outside of the door. The battery 7 ensures that the door lock can remain in normal use when the power is off.
[0031] Working principle: After the lock body 1 and the lock box 2 are fixedly installed, when the door is in the closed state, the spring 16 inside the lock body 1 is in the extended state, which will push the connecting block 14 to fit the inner wall of the lock body 1. At this time, the lock tongue 4 is inserted into the lock slot 3. When the door is opened, the electromagnetic block 19 is energized to generate electromagnetic force, thereby adsorbing the lock tongue 4 to move inward and shrink, so that the lock tongue 4 is separated from the lock slot 3 and enters the lock body 1 as a whole, so that the door is opened;
[0032] After the door is opened, the infrared photoelectric sensor 18 will determine the door closed state. When the door is in the normally open state, the electromagnetic block 19 is kept powered, so that the lock tongue 4 continues to shrink inside the lock body 1. When the door is in the closed state, the electromagnetic block 19 is stopped powered. At this time, the spring 16 will push the lock tongue 4 to move outward through the connecting block 14, so that the lock tongue 4 is inserted into the lock groove 3 to ensure that the door is in a self-locking state.
[0033] During manual operation, the hand wheel 17 is rotated to drive the gear 9 inside the lock body 1 to rotate. Since the outer side of the gear 9 is meshed with the tooth groove 13, the tooth groove 13 is driven to move along the rotation direction of the gear 9, thereby driving the lock tongue 4 to retract and move inward, thereby disengaging from the lock groove 3 and entering the lock body 1 to open the door. The closed state of the door is judged by the infrared photoelectric sensor 18, and the electromagnetic block 19 is powered to make the lock tongue 4 continue to retract inside the lock body 1. When the door is in the closed state, the electromagnetic block 19 is stopped from being powered. At this time, the spring 16 will push the lock tongue 4 to move outward through the connecting block 14, so that the lock tongue 4 is inserted into the lock groove 3 to ensure that the door is in a self-locking state.
