Detailed Description

The embodiment of a simple door lock according to the present invention will be described in further detail with reference to fig. 1 to 4.

A simple door lock comprises a lock body 1 arranged in a door and a door lock catch box 2 arranged on a door frame, wherein the lock body 1 comprises a lock shell 11, and an upper lock tongue 12 and a lower lock tongue 13 are arranged in the lock shell 11; a first magnet 1211 is arranged on the outer side of the upper bolt 12, and a return spring 3 which enables the upper bolt 12 to retract into the lock body 1 is arranged on the inner side of the upper bolt;

the door keeper 2 is provided with a second magnet 21 disposed opposite to the first magnet 1211 and a locking groove 22 engaged with the lower latch 13,

when the door is closed, the suction force generated between the second magnet 21 and the first magnet 1211 sucks the locking tongue 12 out of the lock body 1 and abuts against the second magnet 21, and the locking tongue 12 compresses the return spring 3; when the door is pushed by hand, the pushing force overcomes the attraction force applied to the upper lock tongue 12, so that the upper lock tongue 12 is separated from the second magnet 21, and at the moment, the upper lock tongue 12 slides into the lock body 1 under the action of the return spring 3; a door lock handle is not required to be installed, so that the door is more attractive; the upper bolt 12 does not need to be opened by rotating the door lock handle, so that the lock body 1 has a simple structure and is convenient to open; thereby effectively prolonging the service life of the lock body 1.
