Wherein, one side of the first pushing block 20 facing away from the lock tongue is provided with an inclined plane, and the inclined direction of the inclined plane intersects with the second direction, so that the first pushing block can push the locking block rear jack post 16 to move along the second direction in the process of moving along the first direction X.
Referring to fig. 4 and 5, in the process of switching the locking state to the unlocking state, when the door is in the closed state and locked, the driving mechanism 6 drives the transmission pull rod 7 to pull upwards along the second direction Y, so that the front jacking post 17 of the pulling locking block links the first locking block 11 to rotate upwards along the second direction Y, the second end 112 of the first locking block 11 is separated from the upper jacking post 14 of the locking bolt, at the moment, the door is pushed out of the door, the locking bolt 4 is extruded by the buckle plate and can rotate out of the door and slide towards the inner side of the lock body in the limiting notch of the side panel of the lock body, and accordingly the locking bolt 4 is retracted to unlock the door, and the door is opened. After the door is opened, the lock tongue 4 pops up under the action of the connecting rod pressure spring 2. Simultaneously, when the lock tongue 4 slides backwards, the lock tongue lower jacking column 15 presses the second lock block 12 to enable the second lock block 12 to move towards the clutch block 13 along the first direction X, so that the locking pin 152 of the clutch block 13 is overlapped with the fourth limit block 19 again in the first direction X under the action of the clutch torsion spring 9, the unlocking block position is limited, the lock block rear jacking column 16 is linked with the first lock block 11 to keep the supported state, the second end 112 of the lock block is kept in a non-contact state with the lock tongue upper jacking column 14, the lock tongue 412 can be freely rotated and retracted, the lock body is kept to be in a non-locking state, and the door is in a channel state until the next locking operation.
According to the application, the first locking piece 11 and the second locking piece 12 are used for simultaneously locking the lock tongue 4, and the first locking piece 11 and the second locking piece 11 are required to be simultaneously unlocked when the lock tongue 4 is required to be unlocked, so that the door lock has higher safety performance.
It will be appreciated that, in the process of switching the locked state to the unlocked state, the driving mechanism 6 drives the transmission pull rod 7 to move along the second direction Y, so that the first pushing block 20 contacts the locking block rear jack post 16 to drive the second end 112 of the first locking block 11 to be dislocated with the locking bolt upper jack post 14 in the first direction X, and the fourth limiting block 19 and the locking pin of the clutch block 13 are at least partially overlapped in the first direction X.
