It can be understood that the multi-lock point design improves the anti-theft performance of the door lock, and can still keep the locking state of other lock points even if one lock point is damaged, thereby increasing the difficulty of illegal invasion. And the multi-lock-point escape lock integrates the unlocking actions of the main lock and the auxiliary lock into one-time operation through the linkage structure, so that the operation steps during escape are greatly simplified, the efficient synchronous actions of the main lock tongue 120 and the auxiliary lock tongue 220 are realized, and the operation convenience and reliability of the lockset are remarkably improved.

Referring to fig. 1, in some embodiments, the secondary lock assembly 200 is provided with two secondary lock assemblies 200, the two secondary lock assemblies 200 being symmetrically disposed above and below the primary lock assembly 100, respectively. Specifically, the driven block 150 is movably disposed in the main lock housing 110, and the driven block 150 and the linkage block 140 are respectively connected through the driven rod 300 and drive the two auxiliary lock assemblies 200 to be unlocked. When the driving block 130 rotates, the linkage block 140 is pushed and drives one auxiliary lock assembly 200 to unlock, and simultaneously, the movement of the linkage block 140 drives the driven block 150 to move, and the driven block 150 drives the other auxiliary lock assembly 200 to unlock through the driven rod 300. Not only has strengthened the whole steadiness of lock, still makes the lock provide effectual locking in a plurality of directions, has further promoted the security. Through the cooperation of driven block 150 and linkage piece 140, realized the synchronous unblock of two auxiliary lock assemblies 200, simplified transmission structure, and once operation can unlock two auxiliary lock assemblies 200 simultaneously, improved escape efficiency.

The arrangement of the guide side wall 180 ensures that the moving directions of the linkage block 140 and the driven block 150 are accurate, and the transmission precision and stability are improved.

Further, a limit lever 170 is disposed in the main lock housing 110, and the limit lever 170 is disposed near the two driven levers 300. When the driven rod 300 moves, the driven rod 300 abuts against the limiting rod 170 to limit the moving range, so that the mechanism is prevented from being damaged due to excessive movement of the driven rod 300. The present utility model provides a reset boss 152 on the follower block 150, and a reset spring 171 is connected between the reset boss 152 and the stopper 170. When the driven block 150 is pushed to move, the return spring 171 is compressed, and when the external driving force is removed, the return spring 171 releases energy and drives the driven block 150 and the auxiliary bolt 220 to return. The reset spring 171 enables the driven block 150 and the auxiliary bolt 220 to be automatically reset after unlocking, thereby improving the reliability and durability of the door lock. The auxiliary bolt 220 does not need to be reset manually, and the operation process is simplified.
