Problems solved by technology

[0002] At present, there are two types of letter box locks: one is the mechanical lock structure, which has a low safety factor and is easy to be opened by force. After a long time, the mechanical structure is worn or corroded, and the switch is more troublesome, and the key is easy to lose, which is very inconvenient; The other is the automatic lock, which transmits mechanical movement through electromagnetic drive to achieve tripping and realizes intelligence. However, if the electromagnetic transmission is disturbed, the purpose of tripping cannot be achieved, the lock cannot be unlocked, and the structure is complicated.

Embodiment Construction

[0010] A method and device for electromagnetic locking of a letter box. The lock nail 4 and the lock nut 5 are respectively installed on the letter box unit door 8 and the letter box unit 7. The locking principle: close the letter box unit door 8 and lock it After the nail 4 is inserted into the buckle lock nut 5, the four small steel balls in the buckle lock nut 5 will slide to the position of the groove on the buckle lock nail 4; and the iron ring 2 on the iron ball 3 is under the pressure of the top spring 1 , firmly clamp them in the groove, and lock the mailbox unit door 8; unlocking principle: the card reader accepts the data information on the magnetic card and sends the signal to the controller, and the controller, according to the sensed data information, The electromagnetic lock opening signal of the designated mailbox unit 7 is output and transmitted to the strong magnetic transmitter 6. When a strong magnetic field is applied to the upper part of the magnetic buckle...

Abstract

The invention relates to an electromagnetism lock catch method and device for a mailbox. Each mailbox unit is provided with a female lock catch, a mailbox unit door is provided with a lock catch pin, a card reader receives data information on a magnetic card and sends signals to a controller, the controller outputs a specified mailbox unit electromagnetism opening signal and transmits to a strong magnetic emitter according to the sensed data information, when a high magnetic field is applied to the upper portion of the female electromagnetism lock catch, an iron loop and small steel balls compress a spring and move upward through the attraction of the high magnetic force, so that the lock catch pin is taken out of an opening easily, the electromagnetism lock catch is demagnetized, and the mailbox door is bounced off.

Description

technical field [0001] The invention relates to an electromagnetic lock, in particular to a method and device for electromagnetic locking of a mailbox. Background technique [0002] At present, there are two types of letter box locks: one is the mechanical lock structure, which has a low safety factor and is easy to be opened by force. After a long time, the mechanical structure is worn or corroded, and the switch is troublesome, and the key is easy to lose, which is very inconvenient; The other is the automatic lock, which transmits mechanical movement through electromagnetic drive to achieve tripping and realizes intelligence. However, if the electromagnetic transmission is disturbed, the purpose of tripping cannot be achieved, and the lock cannot be unlocked, and the structure is complicated. Contents of the invention [0003] In order to solve the above problems, the present invention provides a simple, safe and easy-to-use electromagnetic snap lock for a mailbox and i...
