Claims

1. A new door anti-mislock structure, characterized in that, It includes a locking linkage arm (1), a ratchet linkage arm (2), a ratchet (3), an opening linkage arm (4), a pawl linkage arm (5), and a pawl (6); The locking linkage arm (1) rotates around its own axis, with a first limiting part (101) at one end and a toggle part (102) at the other end. The ratchet linkage arm (2) rotates between the open and closed positions around its own axis. A second limiting part (201) is provided on one side. When the ratchet linkage arm (2) is in the open position, the first limiting part (101) and the second limiting part (201) are opposite to each other and prevent the locking linkage arm (1) from rotating to one side. When the ratchet linkage arm (2) is in the closed position, the first limiting part (101) and the second limiting part (201) are misaligned and the locking linkage arm (1) rotates freely to one side. The ratchet (3) is coaxially connected to the ratchet linkage arm (2); The opening linkage arm (4) is provided with a first hook part (401) and a third limiting part (402) at one end near the ratchet linkage arm (2), and the actuating part (102) abuts against the side of the third limiting part (402) facing the pawl linkage arm (5). The pawl linkage arm (5) rotates around its own axis, and a second hook (501) is provided on one side to hook with the first hook (401); The pawl (6) is coaxially connected to the pawl linkage arm (5) and can engage or disengage with the ratchet (3).

2. The novel door inadvertent locking prevention structure according to claim 1, characterized in that, The locking linkage arm (1) also includes: The protrusion (103) is used for the transmission connection of the central control mechanism of the door lock.

3. The novel door inadvertent locking prevention structure according to claim 1, wherein Also includes: A micro-motion signal switch (7) is located on one side of the ratchet linkage arm (2); When the ratchet linkage arm (2) is in the open position, the ratchet linkage arm (2) is in contact with the micro-motion signal switch (7); When the ratchet linkage arm (2) is in the closed position, the ratchet linkage arm (2) is separated from the micro-motion signal switch (7).

4. The novel door inadvertent locking prevention structure according to claim 3, characterized in that: The ratchet linkage arm (2) is circumferentially connected with an arc surface (2b) and a plane (2c); When the ratchet linkage arm (2) is in the open position, the arc surface (2b) is opposite to and in contact with the micro-motion signal switch (7); When the ratchet linkage arm (2) is in the closed position, the plane (2c) is opposite to and separated from the micro-motion signal switch (7).
