Abstract
Description
Technical Field
[0001] The utility model relates to the field of locks, in particular to a magnetic bead lock core. Background Art
[0002] The lock core is mainly composed of a lock core and a lock shell. The lock core is arranged in the lock shell. When in use, a pre-matched key is inserted into the lock core, and then the key is turned to drive the lock core to rotate to unlock the lock. The existing key's teeth cooperate with the accessories in the lock core to unlock the lock. Therefore, the existing key is easily imitated by criminals to illegally unlock the lock, and the security is poor. Utility Model Content
[0003] The utility model solves the problem of poor safety of existing locks.
[0004] The technical solution adopted by the utility model is: a magnetic bead lock core, including a lock core and a magnetic bead key, the lock core including a lock core and a lock shell, the lock core is arranged in the lock shell, a magnetic bead ball is arranged in the lock core, a magnetic bead spring is arranged between the magnetic bead ball and the lock core, and the elastic force of the magnetic bead spring itself pushes one end of the magnetic bead ball to fall into the lock shell, so that the lock core and the lock shell are connected by the magnetic bead ball and cannot be rotated to unlock, and the magnetic bead key is provided with a neodymium iron boron magnet for controlling the movement of the magnetic bead ball in the lock core.
[0005] Furthermore, magnetic bead holes are provided in both the lock core and the lock shell.
[0006] Furthermore, a positioning ring is provided on the outer periphery of the magnetic bead ball, and the magnetic bead spring is sleeved on the outer side of the magnetic bead ball. One end of the magnetic bead spring abuts against the positioning ring and the other end abuts against the side wall of the magnetic bead hole of the lock core.
[0007] Compared with the prior art, the utility model has the following beneficial effects: the magnet in the magnetic bead key drives the magnetic bead ball to move in the lock core, and controlling the switch between the lock core and the lock shell can increase the safety of the lock core.

[0013] like Figures 1 to 4 A magnetic bead lock core comprises a lock core 10 and a magnetic bead key 20. The lock core 10 comprises a lock core 11 and a lock shell 12. The lock core 11 is arranged in the lock shell 12. A magnetic bead ball 13 is arranged in the lock core 10. A magnetic bead spring 14 is arranged between the magnetic bead ball 13 and the lock core 11. The elastic force of the magnetic bead spring 14 itself pushes one end of the magnetic bead ball 13 to fall into the lock shell 12, so that the lock core 11 and the lock shell 12 are engaged and connected by the magnetic bead ball 13 and cannot be rotated to unlock. The magnetic bead key 20 is embedded with a neodymium iron boron magnet 21.
[0014] When in use, the magnetic key 20 is inserted into the lock core 11, and the magnetic bead ball 13 in the lock core 10 is attracted by the neodymium iron boron magnet 21 of the magnetic bead key 20, so that one end of the magnetic bead ball 13 leaves the lock shell 12. At this time, the lock core 11 is separated from the lock shell 12, so that the key can open the lock core normally. Even if other people's keys have the correct teeth, they cannot open the lock core normally if the magnetic ball is not separated from the shell. Therefore, the lock core structure greatly enhances the security of the lock core.
[0015] The lock core 11 and the lock shell 12 are both provided with a magnetic bead hole, and the outer periphery of the magnetic bead ball 13 is provided with a positioning ring 131. The magnetic bead spring 14 is sleeved on the outer side of the magnetic bead ball 13, and one end of the magnetic bead spring 14 abuts against the positioning ring 131 and the other end abuts against the side wall of the magnetic bead hole of the lock core 11. One end of the magnetic bead ball 13 is pushed by the magnetic bead spring 14 to fall into the magnetic lock hole of the lock shell 12, so that the lock shell 12 and the lock core 11 are stuck by the magnetic bead ball 13 and cannot rotate.
[0016] In summary, the magnetic bead lock core of the present invention drives the magnetic bead ball 13 to move in the lock core 10 through the magnet 21 in the magnetic bead key 20, and controls the switch between the lock core 11 and the lock shell 12 to increase the security of the lock core.
