Description

Magnetic lock box

The present invention relates to a magnetic lock box, especially a lock that achieves the purpose of locking by attracting magnetic poles in the closed state.

Locks currently used in door panels usually have a protruding tongue part. During the door closing process, the tongue part can be elastically pushed back and smoothly snapped into the button hole of the door frame. However, when the lock tongue is forced to retreat, an impact sound will be generated due to the impact, and the lock may be easily damaged.

For this reason, as my country's new patent M575047 discloses a "magnetic buckle lock", which includes a magnetic buckle device (10) and a buckle device (20). The magnetic buckle device (10) is used to set a door panel. The magnetic buckle device (10) includes a shell base (11), a magnetic buckle component (12) and a locking mechanism (13). The magnetic buckle component (12) is disposed in the shell seat (11), the magnetic buckle assembly (12) includes a latch portion (121), a magnetic conductive member (122) and at least a latch portion return spring (123), the The latch portion (121) is horizontally movable in the shell seat (11). The latch portion (121) includes a buckle portion (124). The buckle portion (124) can protrude from the shell A seat (11), the magnetically permeable member (122) is arranged at the buckle part (124) of the bolt part (121), and the bolt spring (123) is arranged in the shell seat (11) , And the lock tongue return spring (123) connects between the housing (11) and the lock tongue (121), and provides a reset spring force to the lock tongue (121), and the lock mechanism (13) It is arranged in the shell seat (11) and connected with the latch portion (121) of the magnetic buckle assembly (12), and is used to control the latch portion (121) to protrude or retract the shell seat (11).

Although the previous case of the above patent solves the problem of Xi Zhi's lock colliding with the locking tongue when closing the door, the locking tongue (121) and the interlocking plate (131) of the locking mechanism (13) in this case are independent Components, the interlocking plate (131) pulls the lock tongue (121) with a thin shaft pin, which is easy to break due to fatigue after long-term use, causing damage to the lock; in addition, the case is locked by a small The buckle of the positioning protrusion (141) and the slightly recessed locking position (114) of the housing is prone to lose the locking effect due to wear after long-term use, and it is obviously necessary to improve.
