The middle of the power distribution cabinet housing 1 is slidable, and a mounting block 8 is arranged above the sliding bar 7. The mounting block 8 is installed inside the power distribution cabinet housing 1. A threaded sleeve 16 is arranged in the middle of the mounting block 8. A rotating interface is arranged between the threaded sleeve 16 and the mounting block 8. The threaded sleeve 16 can rotate in the middle of the mounting block 8. Threaded rods 11 are arranged on the outer wall of the mounting block 8 at both ends of the threaded sleeve 16. The threaded rod 11 is threadedly connected to the mounting block 8. The threads of the threaded rods 11 at both ends of the threaded sleeve 16 are in opposite directions. When the threaded sleeve 16 rotates, the threaded rods 11 at both ends will move in the same or opposite directions in the middle of the mounting block 8. The rear ends of the threaded rods 11 are provided with movable plates 9. The movable plates 9 move in the same or opposite directions through the threaded rods 11. Two sets of limiting telescopic rods 12 are provided between the upper side wall of the movable plate 9 and the side wall of the mounting block 8. The limiting telescopic rods 12 are used to prevent the movable plate 9 and the threaded rod 11 from rotating with the threaded sleeve 16. The lower side wall of the movable plate 9 is provided with two sets of connecting telescopic rods 14. The outer wall of the telescopic rod 14 is provided with a spring 15, and the front end of the telescopic rod 14 is provided with a locking clamp 13. The telescopic rod 14 is used to connect the locking clamp 13 with the movable plate 9. The spring 15 provides elastic force. There is a large friction between the locking clamp 13 and the side wall of the sliding bar 7. After the locking clamp 13 clamps the sliding bar 7, it can be fixed in the middle of the sliding groove 5. The telescopic rod 14 and the spring 15 are used to prevent the locking clamp 13 from exerting too much pressure on the sliding bar 7, causing its deformation.

A worm 18 is provided on the upper end of the worm gear 17 inside the mounting block 8, and a rotation interface is provided between the worm 18 and the inner wall of the mounting block 8, so that the worm 18 can rotate inside the mounting block 8, and the rotation of the worm 18 drives the worm gear 17 to rotate. Rotation rods 10 are provided on the outside of the mounting block 8 at both ends of the worm 18, and a rotation interface is provided between the rotation rod 10 and the inner wall of the distribution cabinet housing 1, and the rotation rod 10 can rotate on the inner wall of the distribution cabinet housing 1. The worm 18 is connected to the rotating rod 10, and the rotating rod 10 can drive the worm 18 to rotate. A knob joint 6 is provided at the upper end of the front outer wall of the distribution cabinet housing 1, and a hexagonal interface is provided in the middle of the knob joint 6. The knob joint 6 is connected to the rotating rod 10, and rotating the knob joint 6 can drive the rotating rod 10 to rotate. A plurality of heat dissipation holes 4 are provided on the side wall of the distribution cabinet housing 1. The heat dissipation holes 4 are used to dissipate heat for the circuit components inside the drawer-type cabinet body 2. A handle 3 is provided at the front end of the drawer-type cabinet body 2. The handle 3 facilitates people to pull the drawer-type cabinet body 2 out of the distribution cabinet housing 1.

[0025] It should be noted that the utility model is a drawer-type distribution cabinet with a locking mechanism. When in use, the power personnel use a hexagonal rod to connect the knob joint 6 and rotate it to drive the rotating rod 10 to rotate inside the distribution cabinet housing 1. When the rotating rod 10 rotates, it drives the worm 18 inside the mounting block 8 to rotate. When the worm 18 rotates, the threaded sleeve 16 is driven to rotate in the middle of the mounting block 8 through the worm gear 17. When the threaded sleeve 16 rotates, the threaded rods 11 at both ends will move in the middle of the threaded sleeve 16, and then can drive the movable plate 9 to move. The movable plate 9 can drive the locking clamping plate 13 to move, and the locking clamping plate 13 of the lower side wall is tightly attached to the side wall of the sliding bar 7. The sliding bar 7 is clamped, so that the sliding bar 7 can be fixed in the middle of the sliding groove 5. In this way, the drawer-type cabinet body 2 can be locked in the middle of the distribution cabinet housing 1 to prevent non-professionals from opening it.
