[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Figure 1-Figure 4, a high and low voltage electrical cabinet with adjustable internal space, comprising a hollow cabinet body 1, an opening on one side of the hollow cabinet body 1 is provided with a cabinet door 10, a handle is installed on one side of the cabinet door 10, and an anti-slip pattern is provided on the handle, a telescopic frame 2 is slidably provided on the opening on one side of the hollow cabinet body 1 away from the cabinet door 10, the length of the telescopic frame 2 is less than the length of the hollow cabinet body 1, and a hollow frame 3 is fixedly connected to the side of the telescopic frame 2 away from the cabinet door 10, and support frames 5 are fixedly connected to the two outer side walls of the hollow frame 3, and a plurality of universal wheels 12 are provided at the bottom of the hollow frame 3, so that the hollow frame 3 can be conveniently moved and positioned when moving, and a telescopic mechanism connected to the hollow cabinet body 1 is provided on the inner sides of the two support frames 5, and the telescopic mechanism includes a support column 6 fixedly connected to the outer side wall of the hollow frame 3, and the contact surface of the support column 6 and the hollow frame 3 is welded, and a threaded rod 9 is rotatably connected to the side wall of the support column 6, and a threaded groove 8 is provided in the side wall of the hollow cabinet body 1, and the threaded rod 9 is away from the support column 6. One end is screwed into the side wall of the hollow cabinet 1 through a threaded groove 8, and the length of the threaded groove 8 is consistent with the length of the telescopic frame 2. A worm gear 11 is fixedly sleeved on one end of the threaded rod 9 close to the support column 6, and the worm gear 11 is connected to the driving mechanism. A driving mechanism connected to the telescopic mechanism is provided inside the hollow frame 3. The driving mechanism includes a double-headed motor 7 fixedly connected to the inner wall of the hollow frame 3, and two output shaft ends of the double-headed motor 7 are respectively fixedly connected with a worm 4. One end of the two worms 4 away from the double-headed motor 7 passes through the side wall of the hollow frame 3 and extends to the outside of the hollow frame 3. One end of the two worms 4 located outside the hollow frame 3 is respectively meshed with a worm gear 11, and the worm 4 is driven to rotate by the double-headed motor 7. The transmission action of the worm 4 and the worm gear 11 further drives the threaded rod 9 to rotate. Under the action of the threads of the threaded rod 9 and the threaded groove 8 on the telescopic frame 2, front and rear linear movement is realized in the hollow cabinet 1, and one end of the two worms 4 located outside the hollow frame 3 is rotatably connected to the side wall of the support frame 5.

[0023] When the utility model is used, a worker starts the double-headed motor 7 to drive the two worm gears 4 to rotate, and the rotation of the two worm gears 4 drives the two threaded rods 9 to rotate. The two threaded rods 9 move back and forth under the action of the threads of the two threaded grooves 8 on the hollow cabinet 1. Since the threaded rods 9 are connected to the support columns 6, and the support columns 6 are connected to the telescopic frame 2, the threaded rods 9 will drive the telescopic frame 2 when they move, and the movement of the telescopic frame 2 drives the fixedly connected hollow frame 3. Since a plurality of universal wheels 12 are provided at the bottom of the hollow frame 3, the telescopic frame 2 can be moved to a suitable position more conveniently.
