Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figures 1-6 As shown, this utility model provides a technical solution: an automatic locking structure for a switch cabinet, comprising a cabinet body 1 and a cabinet door 3 movably connected to it via a hinge 2. A handle groove 4 is provided on the outer surface of the cabinet door 3, and a groove 12 is formed on the inner side of the cabinet body 1, with the groove 12 communicating with the handle groove 4. A movable handle 5 is installed in the handle groove 4, and threaded rods 6 are fixed to the upper and lower ends of the handle 5. A rotating shaft 9 is connected to the other end of the threaded rod 6, and a bearing 10 is sleeved on the surface of the rotating shaft 9. The bearings 10 are fixed to the symmetrical inner walls of the groove 12. A locking mechanism 8 that can move up and down is sleeved on the surface of the threaded rod 6. Bolts 7 are provided at the top and bottom of the locking mechanism 8. Through the threaded fastening action between the upper and lower bolts 7 and the threaded rod 6, the locking mechanism 8 can be fixed at different positions in the groove 12 of the cabinet door 3 as needed. The inner wall of the box body 1 is provided with a fastening wheel 11 that is compatible with the locking mechanism 8. The handle 5 in the handle groove 4 drives the threaded rod 6 to rotate. At the same time, the rotating shafts 9 at both ends of the threaded rod 6 will also rotate in the corresponding bearings 10. This allows the locking mechanism 8 and the fastening wheel 11 to be engaged and disengaged for locking and unlocking. The operation is simple and intuitive, without the need for complicated tools and cumbersome steps, which greatly improves work efficiency.

[0025] The combination of locking mechanism 8 and fastening wheel 11 ensures that cabinet door 3 can be quickly closed and opened with hinge 2, which is faster, more time-saving and labor-saving than traditional key opening. The embedded locking mechanism 8 can also prevent rainwater from wetting and subsequent damage.

[0026] Specifically, the locking mechanism 8 includes a fixed block 81 sleeved on the surface of the threaded rod 6 and capable of sliding up and down, the upper and lower surfaces of the fixed block 81 are fixed with the threaded rod 6 through the bolt 7, the other end of the fixed block 81 is movably connected with the connecting block 83 through the upper and lower arranged pin shafts 82, the other end of the connecting block 83 is also movably connected with the pawl 84 matched with the fastening wheel 11 through the pin shaft 82, the pin shafts 82 at both ends of the connecting block 83 are provided with the snap spring 85, and under the elastic force of the snap spring 85, the angle between the connecting block 83 and the fixed block 81 and the angle between the connecting block 83 and the pawl 84 can be limited.

[0027] The combination of the threaded rod 6, the rotating shaft 9, the bearing 10 and the bolt 7 makes the locking mechanism 8 more stable and reliable during operation, meanwhile, the snap spring 85 in the pin shaft 82 at both ends of the connecting block 83 can limit the angle between the connecting block 83 and the fixed block 81 and the angle between the connecting block 83 and the pawl 84, thereby enhancing the stability of the entire locking structure, reducing the probability of failure caused by looseness or shaking, and the snap spring 85 can also make the pawl 84 and the connecting block 83 rebound to the locked state when closing the cabinet door 3.

[0028] Working principle: when opening, the operator puts his hand into the handle slot 4 to pull the inner handle 5, the handle 5 drives the threaded rods 6 at both ends to rotate in the bearing 10 through the rotating shaft 9, and then the threaded rods 6 also drive the locking mechanism 8 fixed through the bolt 7 to rotate, the fixed block 81 in the locking mechanism 8 drives the connecting block 83 and the pawl 84 to rotate by 180 degrees, so that the pawl 84 is separated from the fastening wheel 11 to open the cabinet door 3.

[0029] When closing, the handle does not need to be pulled, and the cabinet door 3 is directly pushed to close, first, the pawl 84 is pressed onto the box body 1, and then the pawl 84 slides over the surface of the fastening wheel 11, and the elastic force of the snap spring 85 makes the pawl 84 return to the clamping state.
