[0021] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0022] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0023] like Figure 1-4As shown, an electrical engineering control cabinet comprises a cabinet body 1 and a frame plate 2 for installing equipment in the cabinet body 1, both sides of the bottom of the cabinet body 1 are rotatably connected to a rotating screw rod 4 and a fixed screw rod 3, and both sides of the cabinet body 1 are provided with lifting shells 7 sleeved on the rotating screw rod 4 and the fixed screw rod 3, the lifting shells 7 are used to install the frame plate 2, both sides of the frame plate 2 are allocated with lifting shells 7, and the frame plate 2 and the outer wall of the lifting shells 7 are connected by bolts, therefore, the installation position of the frame plate 2 can be adjusted by lifting the lifting shells 7 between the fixed screw rod 3 and the rotating screw rod 4, when adjusting the installation height of the lifting shell 7, the rotating screw rod 4 is used to rotate and drive the lifting shell 7 to lift, so that the lifting shell 7 can be finely adjusted, and then the installation distance between two adjacent frame plates 2 can be finely adjusted, and after the height adjustment is completed, By using the lifting shell 7 to resist the fixed screw rod 3 and disengage the rotating screw rod 4, the lifting shell 7 can be fixed at a fixed height in the cabinet 1 without changing its position as the rotating screw rod 4 rotates. In order to ensure that the lifting heights of the lifting shells 7 on both sides are consistent, a sprocket 5 is fixedly connected to the bottom edge of the surface of the rotating screw rod 4, and a chain 6 is meshed and connected between the two sprocket wheels 5. A motor 9 for driving one of the rotating screw rods 4 to rotate is fixedly connected to the bottom of the cabinet 1. The corresponding rotating screw rod 4 is driven to rotate by the motor 9, and the other rotating screw rod 4 is synchronously rotated under the connection between the sprocket 5 and the chain 6. Installation ports 8 for placing the lifting shell 7 are provided on both sides of the cabinet top in the cabinet 1. Through the installation ports 8, it is convenient for personnel to place a certain number of lifting shells 7 in the cabinet 1 and install them on the fixed screw rod 3 and the rotating screw rod 4:

[0024] In order to achieve the height adjustment and height fixing of the lifting shell 7: the inner wall of the lifting shell 7 is slidably connected with two symmetrically distributed sliding seats 13, and a block 14 is installed in the sliding seat 13. The two blocks 14 are respectively used to be threadedly connected with the rotating screw rod 4 and the fixed screw rod 3. A transparent window 12 is provided at the position of the block 14 on the front surface of the lifting shell 7. The sliding seat 13 slides to realize that the internal block 14 moves to engage with the corresponding fixed screw rod 3 or the rotating screw rod 4. Therefore, a spiral groove with the same inclination as the thread groove on the fixed screw rod 3 or the rotating screw rod 4 is opened on the side of the block 14. When one of the blocks 14 is threadedly connected with the corresponding rotating screw rod 4 and the other block 14 is disengaged from the corresponding fixed screw rod 3, the lifting shell 7 is sleeved on the fixed screw rod 3 and the rotating screw rod 4 to make the lifting shell 7 and the internal block 14. Therefore, by rotating the rotating screw rod 4, the block 14 threadedly connected thereto can drive the lifting shell 7 to rise and fall. The mounting height of the frame plate 2 can be adjusted. When it is adjusted to an appropriate height, the other block 14 moves with the movement of the sliding seat 13 to engage with the surface of the fixed screw rod 3. The block 14 threadedly connected to the rotating screw rod 4 is disengaged from the rotating screw rod 4 as the sliding seat 13 moves. Therefore, the fixed screw rod 3 cannot rotate, so the position of the lifting shell 7 is fixed, and the position will not change with the rotation of the rotating screw rod 4. The outer wall of the sliding seat 13 is threadedly connected to a threaded rod 15 rotatably connected to the inner wall of the lifting shell 7. A worm gear 16 is fixedly connected to the threaded rod 15. The inner wall of one side of the lifting shell 7 is rotatably connected to a worm 11 that passes through the inner wall of the other side and meshes with the worm gear 16. One end of the worm 11 passes through one side of the lifting shell 7 and extends outward. Therefore, the worm gear 16 that meshes with the worm gear 11 drives the threaded rod 15 to rotate, so that the sliding seat 13 threadedly connected to the threaded rod 15 can drive the block 14 to slide horizontally.

[0025] In addition, when the height of the lifting shell 7 is adjusted so that the block 14 cannot engage with the fixed screw rod 3 or the rotating screw rod 4, the block 14 is inserted into the sliding seat 13 in the longitudinal direction, and the sliding seat 13 is rotatably connected with a long bolt 10 with a thread penetrating the bottom edge of the block 14. By rotating the long bolt 10, the block 14 threadedly connected with the long bolt 10 is lifted and lowered in the sliding seat 13 for fine-tuning of the position, which can ensure that the block 14 is smoothly engaged with the spiral grooves with the same inclination on the fixed screw rod 3 and the rotating screw rod 4. The top and bottom of the lifting shell 7 are both provided with sliding grooves 17 at the positions of the sliding seat 13. The outer wall of the sliding seat 13 extends outward with a T-shaped protrusion for inserting with the sliding groove 17, and one end of the long bolt 10 penetrates the sliding groove 17 at the top of the lifting shell 7. The provided sliding groove 17 ensures that the sliding seat 13 can only move relative to the corresponding fixed screw rod 3 or rotating screw rod 4.

[0026] Working principle: the first lifting shell 7 is installed on the fixed screw rod 3 and the rotating screw rod 4 through the installation opening 8, and falls on the bottom of the cabinet 1, and the frame plate 2 is installed between the two lifting shells 7. The worm 11 is rotated to realize the meshing transmission of the worm wheel 16 to drive the threaded rod 15 to rotate, so that the sliding seat 13 threadedly connected with the threaded rod 15 drives the block 14 to slide horizontally, and then the long bolt 10 is rotated to realize the position fine adjustment of the block 14. The block 14 moves with the movement of the sliding seat 13 until one of the blocks 14 is threadedly connected with the corresponding rotating screw rod 4, and the other block 14 is threadedly connected with the corresponding fixed screw rod 3. After the lifting shell 7 is disengaged, the motor 9 drives the corresponding rotating screw rod 4 to rotate, and under the connection between the sprocket 5 and the chain 6, another rotating screw rod 4 is rotated synchronously, so that the lifting shell 7 drives the shelf plate 2 to move to the corresponding height in the cabinet 1, and then the position of the sliding seat 13 is adjusted again. Another block 14 moves with the movement of the sliding seat 13 to engage with the surface of the fixed screw rod 3, and the block 14 threadedly connected with the rotating screw rod 4 is disengaged from the rotating screw rod 4 with the movement of the sliding seat 13, so that the height position of the lifting shell 7 and the shelf plate 2 on its surface can be completely fixed. By analogy, other lifting shells 7 and shelf plates 2 can be installed.

[0027] The wiring diagram of the motor 9 in the present invention is common knowledge in the art, and its working principle is a known technology. The model is selected according to the actual use, so the control method and wiring arrangement of the motor 9 are not explained in detail.
