Keyhole-free magnetic mechanical password lock
A keyhole-free magnetic mechanical password lock comprises a housing, wherein a password input area capable of attracting magnetic blocks is arranged on the front surface of the housing, a magnetic head array plate is arranged in the housing corresponding to the password input area, a magnetic head transversely facing the password input area is arranged on the magnetic head array plate, a non-magnetic lock cylinder is arranged in the housing and is located between the magnetic head array plate and the front surface of the housing, a lock hole for the magnetic head to be inserted therein is formed in the lock cylinder, and the magnetic head comprises a first magnetic head located on the rear side of the lock cylinder and having the tendency that the first magnetic head is always and forwards inserted into the lock hole and a second magnetic head located on the front side of the lock cylinder and having the tendency that the second magnetic head is always and backwards inserted into the lock hole. The keyhole-free magnetic mechanical password lock can be unlocked only through several magnetic blocks. In addition, by means of an unlocking structure utilizing attraction force and repellent force to enable the magnetic head to retreat from the lock hole, password modification and setting performed by a user are facilitated, and a spectator can be further prevented from peeping and sounding out a password.
