[0042] The upper end of the transmission plate 1122 is provided with a mating arm that cooperates with the unlocking slider 1121, and the lower end is provided with a mating groove that cooperates with the unlocking plate 1123, so that the transmission plate 1122 can better transmit power between the unlocking slider 1121 and the unlocking plate 1123.

[0043] The lock housing 11 has two sets of reset components 113 facing each other. The compression part 11211 on one side of the unlocking slider 1121 is placed between the two reset components 113. The reset component 113 includes a reset spring 1131 and a reset slider 1132. The swing arm 21 drives the unlocking slider 1121 to slide, and the compression part 11211 pushes the corresponding reset slider 1132 to slide and compresses the reset spring 1131. After the push-pull rod 22 is released, the reset spring 1131 drives the reset slider 1132 to push the unlocking slider 1121 to reset. This allows the unlocking slider 1121 to automatically slide in the opposite direction after unlocking, and drive the swing arm 21 to swing in the opposite direction, and together drive the push-pull rod 22 to achieve automatic reset.

[0044] The unlocking slider 1121 has a linkage shaft 11212 in the middle, and the lower end of the swing arm 21 has a linkage groove 213 that cooperates with the linkage shaft 11212. The left and right ends of the linkage shaft 11212 are respectively placed in the linkage grooves 213 of the two swing arms 21. The swing arm 21 pushes the linkage shaft 11212 through the linkage groove 213 to drive the unlocking slider 1121 to slide, thereby realizing the swing of the swing arm 21 to drive the sliding action of the unlocking slider 1121, thus realizing the unlocking operation of the door lock.

[0047] One end of the anti-locking plate 1142 is provided with an anti-locking part 11421 that cooperates with the unlocking plate 1123, and the other end is provided with an abutment part 11422 that cooperates with the push arm 11412. The lower end of the anti-locking plate 1142 is recessed upward with an arc-shaped groove that is adapted to the push arm 11412. When the anti-locking drive member 1141 is rotated, the push arm 11412 rotates along the arc-shaped groove.

[0048] The push arm 11412 rotates along the arc-shaped groove to the lower end of the anti-locking part 11421 of the anti-locking plate 1142, driving the anti-locking plate 1142 to rotate to the anti-locking position. The push arm 11412 abuts against the lower end of the anti-locking part 11421, locking the anti-locking plate 1142 in the anti-locking position, so that the upper end of the anti-locking part 11421 prevents the unlocking plate 1123 from rotating backward, thereby realizing the anti-locking of the door lock.

[0049] The anti-locking drive 1141, under the action of the positioning torsion spring 11411, stably places the anti-locking plate 1142 in the unlocked position or the anti-locking position;

[0050] The push arm 11412 rotates along the arc-shaped groove to the abutment part 11422 of the anti-locking plate 1142. The push arm 11412 drives the anti-locking plate 1142 to rotate in the opposite direction to the unlock position through the abutment part 11422.
