[0023] In the specific implementation process, Figure 1-Figure 4As shown, an anti-theft lock buckle for outdoor cabinets, optical cross boxes, and fiber distribution boxes is used to connect the cabinet body 1 and the cabinet door 2. A lock hole is opened on the side wall of the cabinet body 1, including a lock body, a lock block and a key column. The lock body is arranged inside the cabinet body 1, and the lock block is fixedly connected to the inside of the cabinet door 2. The lock body and the lock block can be engaged, and the key column can be inserted into the lock body and drive the lock body to move. The lock body includes a lock shell 3, a first spring 4 and a motion block 5. The lock shell 3 provides an outer shell of the lock body, protects the internal structure, and is connected to the first The spring 4 is hinged to provide support for the entire system. The inner side of the lock housing 3 is hinged to one side of the first spring 4. The other end of the first spring 4 is hinged to the motion block 5, connecting the lock housing 3 and the motion block 5. Its elastic force ensures that the motion block 5 can be reset to maintain the normal operation and stability of the lock. A columnar groove 6 is opened on the motion block 5, and six square grooves 7 are evenly opened around the columnar groove 6. The columnar groove 6 is connected to the six square grooves 7. The key column can be inserted into the columnar groove 6 and the six square grooves 7. In the area, the key column includes a motion column 8, and six grooves are evenly opened at one end of the side wall of the motion column 8. Elastic members are provided in the six grooves. The elastic members protrude from the surface of the motion column 8 in the natural state. The height of the elastic member higher than the surface of the motion column 8 is adapted to the height of the square groove 7. The columnar groove 6 and the six square grooves 7 interact with the grooves and elastic members on the key column to realize locking and unlocking actions. The lock block includes a connecting rod 9 and an oblique block 10. One end of the side wall of the connecting rod 9 is fixedly connected to the bottom surface of the oblique block 10. The oblique block 10 is a slope structure away from the side of the cabinet door 2. The elastic member includes a second spring 11 and a limit block 12. One end of the second spring 11 is fixedly connected to the bottom wall of the groove opened by the motion column 8, and the other end of the second spring 11 is fixedly connected to the bottom surface of the limit block 12.

[0024] The working principle of the present invention is as follows: when the cabinet door 2 is closed, the connecting rod 9 located on the inner side of the cabinet door 2 drives the inclined block 10 to move, and the slope of the inclined block 10 contacts the moving block 5. As the cabinet door 2 continues to move, the inclined block 10 squeezes the moving block 5, and the moving block 5 is squeezed and then squeezes the first spring 4. The first spring 4 is squeezed, and the moving block 5 retracts into the lock shell 3 until the cabinet door 2 is closed. The squeezing of the moving block 5 by the inclined block 10 ends, the spring is released, and the moving block 5 pops out of the lock shell 3. The moving block 5 is engaged with the inclined block 10. When the cabinet door 2 needs to be opened, the key column is passed through the lock hole on the cabinet body 1 and the lock hole on the lock shell 3. At this time, multiple limit blocks 12 are in a squeezed state. Multiple second springs 11 are compressed until the limit block 12 completely enters the square groove 7, and multiple second springs 11 are released, and the ends of multiple limit blocks 12 pop out, rotating the motion column 8 clockwise, and the inclined block 10 on the motion column 8 interacts with the square groove 7, driving the motion block 5 to rotate 90 degrees clockwise. At this time, the cabinet door 2 can be opened, and the motion column 8 is released. The first spring 4 acts to drive the motion block 5 to reset. At this time, the motion column 8 is rotated counterclockwise until the limit block 12 is compressed back into the groove on the motion column 8, and the key column is taken out along the lock hole on the lock shell 3 and the lock hole on the cabinet body 1. When the cabinet door 2 needs to be closed, directly push the cabinet door 2. This lock structure can realize self-locking of the cabinet door 2 and the cabinet body 1.
