[0029] Embodiment 1: A door lock for an animal cage comprises a door lock body 1, a lock core 2 is fixedly connected to the front side of the door lock body 1, a lock head 3 is fixedly connected to the top of the lock core 2, an outer wall of the lock head 3 is fixedly connected to the front side of the door lock body 1, a plurality of bullet holes 4 are provided inside the door lock body 1, a plurality of bullet springs 5 ​​are fixedly connected to the inside of the four bullet holes 4, and an unlocking assembly is arranged inside the left side of the door lock body 1.

[0030] Insert the key into the lock cylinder 3 and turn it. The shape of the key will compress the bullet 7 in the lock cylinder 2 to make it consistent with the rotating surface. The bullet spring 5 will place the adjustment block 6 on the same horizontal plane due to the compression, so that the matching key can be inserted into the lock cylinder 3 to open the lock.

[0031] The ends of the four bullet springs 5 ​​away from the door lock body 1 are fixedly connected to a plurality of adjustment blocks 6, and a plurality of bullets 7 are arranged above the four adjustment blocks 6. The unlocking assembly includes a rotating block 8, the outer wall of the rotating block 8 is rotatably connected to the inside of the door lock body 1, and a limiting groove 9 is provided inside the door lock body 1. The left side of the rotating block 8 is clamped on the outer wall of the limiting groove 9, and a switch buckle 11 is slidably connected to the inside of the limiting groove 9. A switch spring 10 is fixedly connected to the bottom of the switch buckle 11, and the end of the switch spring 10 away from the switch buckle 11 is fixedly connected to the inside of the door lock body 1. A sliding groove 12 is provided on the rear side of the door lock body 1, and the outer side of the switch buckle 11 is slidably connected to the inside of the sliding groove 12.

[0032] When the key is inserted and rotated, the rotating block 8 will follow the rotation of the key to squeeze the switch buckle 11 in the limiting groove 9 to move downward. The switch spring 10 below can be retracted, and the switch buckle 11 slides in the slide groove 12 to open the door lock and release the animal in the animal cage.

[0033] Embodiment 2: The ends of the four bullet springs 5 ​​away from the door lock body 1 are fixedly connected to a plurality of adjustment blocks 6 , and a plurality of bullets 7 are arranged above the four adjustment blocks 6 .
