Specifically, the first insertion portion 201 of the fixed push rod 2 is inserted into the sliding groove 101 of the driving push rod 1, and the first insertion portion 201 can slide reciprocally in the sliding groove 101. Meanwhile, a limiting structure is arranged in the sliding groove 101, a limiting protrusion is arranged at a position of the first inserting portion 201 corresponding to the limiting structure, and when the first inserting portion 201 slides outwards to the maximum position, the limiting protrusion can be stopped by the limiting structure, so that the first inserting portion 201 is prevented from being separated from the sliding groove 101. As shown in fig. 2, when the door lock assembly is in the locked state, the driving push rod 1 is disengaged from the lock tongue 3, and the fixed push rod 2 is in the locked position and abuts against the second abutment surface 3012 of the lock tongue 3. The handle 6 is rotated, the driving push rod 1 can be driven to horizontally move towards the direction of the fixed push rod 2 through the connecting rod assembly 4, and the first abutting surface 3011 of the lock tongue 3 is extruded, so that the lock tongue 3 can vertically move to give way and be separated from the fixed push rod 2. At this time, the first elastic element 501 of the positioning device 5 pushes the fixed push rod 2 to horizontally move the fixed push rod 2 toward the driving push rod 1, and slides to the unlocking position, so that the door lock assembly is in the unlocking state, as shown in fig. 3.

When the door lock assembly is in an unlocking state, the handle 6 is pushed, and the driving push rod 1 and the fixed push rod 2 are driven by the connecting rod assembly 4 to horizontally move towards the direction of the lock tongue 3 and press the first abutting surface 3011 of the lock tongue 3, so that the lock tongue 3 vertically moves to give way. When the fixed push rod 2 moves to the locking position, the lock tongue 3 falls down, and the fixed push rod 2 abuts against the second abutting surface 3012 of the lock tongue 3, so that the door lock assembly is in a locking state.

As shown in fig. 1, in some embodiments, the handle 6 includes a cam that abuts the linkage assembly 4. Wherein, when the handle 6 rotates, the connecting rod assembly 4 can be driven to move by the cam.
