Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.

Referring to fig. 1-3, a magnetic self-locking anti-theft warning lock comprises a lock box 1 and a buckle box 3 matched with the lock box 1, wherein the lock box 1 is provided with a plurality of lock pins 2, the lock box 1 is provided with a lock cylinder 9 for controlling the lock pins 2, the buckle box 3 is provided with a plurality of pin grooves 4 matched with the lock pins 2, the lower end surface of each lock pin 2 is vertically provided with a limit groove 5, the top wall in each limit groove 5 is fixedly connected with an electromagnet 6, the bottom wall in each pin groove 4 is vertically provided with a storage groove 7, each storage groove 7 is internally connected with a permanent magnet strip 8 in a sliding manner, and the magnetic poles of one side of each permanent magnet strip 8 opposite to the electromagnet 6 in the corresponding position are opposite;

a placing groove 11 corresponding to the lock core 9 is formed in the lock box 1, a moving contact 13 is elastically connected to the groove wall of the placing groove 11 on one side close to the lock core 9 through a return spring 15, a static contact 12 matched with the moving contact 13 is fixedly connected to the groove wall of the placing groove 11 far away from the lock core 9, a push rod 14 is horizontally and fixedly connected to the middle of the moving contact 13, and one end of the push rod 14 far away from the moving contact 13 extends into the lock core 9;

the lock box 1 is provided with a mounting groove, an insulating roller 16 is rotatably mounted in the mounting groove, a conducting ring 17 is fixedly arranged on the inner bottom wall of the mounting groove, the inner ring of the conducting ring 17 is connected with the outer side wall of the insulating roller 16 in a sealing and sliding manner, a conducting block 18 is embedded on the side wall of the insulating roller 16, an insulating block 19 matched with the conducting block 18 is embedded in the conducting ring 17, a warning indicator 10 is arranged in the lock box 1, the input ends of the warning indicator 10, the static contact 12, the moving contact 13, the conducting ring 17 and each electromagnet 6 are connected with an external power supply in series through conducting wires, two ends of the insulating roller 16 are coaxially and fixedly connected with rotating rods, one end of each rotating rod, which is far away from the insulating roller 16, extends out of the lock box 1 and is fixedly connected with a rotating disc 20, the side walls on two sides of the lock box 1 are respectively provided with a first mark corresponding to the insulating block, further, to ensure confusion, a plurality of marks similar to the first mark may be provided on both side walls of the lock case 1, and a plurality of marks similar to the second mark may be provided on the dial 20.

The invention can be illustrated by the following operating modes: when a user unlocks the lock, firstly, according to the identification of a first mark and a second mark, a rotating disc 20 outside a rotating door drives an insulating roller 16 to rotate so that a conductive block 18 and an insulating block 19 on the insulating roller are opposite to each other to break a circuit, then the door lock is unlocked into a room through the matching of a key and a lock cylinder 9, meanwhile, the key abuts against an ejector rod 14 and drives the ejector rod 14 and a movable contact 13 to move and stretch a reset spring 15 until the movable contact 13 abuts against and is conducted with a static contact 12, and because the conductive block 18 of the insulating block 19 is broken at the position, the alarm 10 cannot work, and then the position of the insulating block 19 and the conductive block 18 is disturbed through the rotating disc 20 in the room so that the conductive block 18 is electrically connected with a conductive ring;

when a thief holds the master key to unlock, the conductive block 18 can be disconnected by the insulating block 19 due to the fact that the thief cannot know the effect of the rotary disc 20 or the angle of the rotary disc 20, when the thief inserts the master key into the lock cylinder, the movable contact 13 is conducted with the fixed contact, the conductive block 18 is conducted with the conductive ring 17, the alarm 10 works to send an alarm to drive the thief and warn nearby residents, meanwhile, the electromagnet 6 sends out a magnetic field after being electrified, the permanent magnet strips 8 move upwards under the magnetic force action of the electromagnet 6 to enter the limiting groove 5 to clamp the lock pin 2, the door cannot be opened, and the thief is prevented from entering the room.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be able to cover the technical scope of the present invention and the equivalent alternatives or modifications according to the technical solution and the inventive concept of the present invention within the technical scope of the present invention.
