In order to solve the above problems, as shown in fig. 1 to 5, the door lock of this embodiment is applied to a box structure, the box structure includes a box and a door, the door is disposed on the box, the door lock includes a lock mechanism and a lock seat mechanism, the lock mechanism is disposed on the door, the lock mechanism includes a base 11, a lock main body, a rotating shaft 13 and a torsion spring 14, the base 11 is disposed on the box, the rotating shaft 13 is disposed on the lock main body and rotatably connected with the base 11, the torsion spring 14 is sleeved on the rotating shaft 13, and two ends of the torsion spring 14 are respectively connected with the base 11 and the lock main body;

the lock seat mechanism is arranged on the box body, and the lock head main body is connected with the lock seat mechanism through the external lock.

In this embodiment, the lock mechanism includes a base 11 and a lock body, and the base 11 and the lock body are connected by using a rotating shaft 13, and the lock body rotates with respect to the base 11 around the rotating shaft 13. Meanwhile, the torsion spring 14 is arranged on the rotating shaft 13, and two ends of the torsion spring 14 are respectively connected to the base 11 and the lock main body, the lock main body rotates relative to the base 11, when the lock main body is close to the lock mechanism, the torsion spring 14 is continuously compressed, and when the lock main body rotates relative to the base 11 and is far away from the lock mechanism, the torsion spring 14 is continuously extended.

In summary, when the door is locked, the lock body is close to the lock seat mechanism, and the lock body and the lock seat mechanism are connected by using the outer padlock, and the torsion spring 14 is in a compressed state. When the door lock is opened, the external lock is firstly opened, the torsion spring 14 extends and generates elasticity to act on the lock head main body, and the lock head main body is driven to rotate relative to the base 11 by taking the rotating shaft 13 as a center, so that the lock head main body is far away from the lock seat mechanism. Therefore, when the door lock is opened, after the external lock is opened, the torsional spring 14 extends and drives the lock head main body to be away from the lock seat mechanism, the lock head mechanism and the lock seat mechanism do not need to be separated manually, the steps of unlocking the door lock are reduced, and the unlocking process of the door lock is simplified.
