A handle 904 is screwed to the middle of the outer side of the connecting strip 902. This structure allows the connecting strip 902 to be locked to the positioning channel steel 8 by the locking bolts 905 when the mounting positioning plate 9 is vertically positioned, ensuring the stability of the mounting positioning plate 9. The handle 904 facilitates the lifting and moving of the mounting positioning plate 9. Connecting shafts 903 are symmetrically inserted into both sides of the upper end of the mounting positioning plate 9, and the connecting shafts 903 are fixed to the side of the movable limiting piece 801, allowing the mounting positioning plate 9 to move relative to the positioning channel steel 8. A positioning support block 804 is welded to the inner side of the positioning channel steel 8, and... The positioning support block 804 is at the same height as the positioning seat 7. An elongated hole is provided on the lower outer side of the positioning channel steel 8. This structure, through the positioning support block 804, restricts the movement range of the movable limiting member 801, allowing the mounting positioning plate 9 to be stably supported when laid flat by the cooperation of the positioning support block 804 and the positioning seat 7. The limiting rod 802 is longitudinally installed above the positioning support block 804, and an elastic support seat 803 is movably fitted onto the limiting rod 802 below the movable limiting member 801. This structure limits the longitudinal movement of the movable limiting member 801 through the limiting rod 802, and the movable limiting member 801 provides shock absorption support to the elastic support seat 803, reducing the vibration force when the movable limiting member 801 moves to its lowest position.

[0020] Working principle: When using this motor control cabinet, the main body 1 of the motor control cabinet first consists of double-layer side panels 2, a back panel 3, a cabinet door 5, and a support base 6, forming a cabinet structure. The double-layer side panels 2 allow ventilation through ventilation holes 202 on the inner side panel, and installation holes 203 are opened on the outer side panel for installing the dust filter 201, ensuring that the gas exchange of the main body 1 of the motor control cabinet has a highly efficient dust removal function. The positioning channel steel 8 is fixed to the double-layer side panels 2 inside the main body 1 of the motor control cabinet with bolts. The mounting positioning plate 9 is connected to the movable limiting component 801 through the connecting shaft 903. This allows the upper position of the mounting positioning plate 9 to move up and down with the cooperation of the movable limiting member 801 and the limiting rod 802. By lifting the mounting positioning plate 9 with the handle 904, the mounting positioning plate 9 rotates relative to the connecting shaft 903, adjusting the angle of the mounting positioning plate 9. As the bottom of the mounting positioning plate 9 is lifted upwards, the upper position of the mounting positioning plate 9 gradually moves downwards. The elastic support seat 803 acts as a shock absorber for the mounting positioning plate 9. During the process of the mounting positioning plate 9 moving from below the positioning seat 7 to above the positioning seat 7, the two sides of the mounting positioning plate 9 push the second movable support. Component 704, together with the first movable support component 702, rotates relative to the positioning seat 7 under the action of the first positioning pin 701. After the mounting positioning plate 9 moves above the positioning seat 7, the first movable support component 702 rotates back to its original position. At this time, the mounting positioning plate 9 is released, allowing it to be stably supported by the positioning support block 804 and the second movable support component 704. This provides sufficient operating space for the electrical components on the mounting rod 901 during installation and maintenance. When re-fixing the vertical position of the mounting positioning plate 9, the entire mounting positioning plate 9 is moved upwards, and then... As the mounting positioning plate 9 rotates, its two sides pass the second movable support 704, causing the inner side of the second movable support 704 to push. At this time, the second movable support 704 rotates through its positioning, allowing the mounting positioning plate 9 to smoothly enter the motor control cabinet body 1. The mounting positioning plate 9 continues to move upward into place. When the connecting strip 902 is in contact with the positioning channel steel 8, the connecting strip 902 and the elongated hole of the positioning channel steel 8 are fixed by the locking bolt 905, thus fixing the mounting positioning plate 9 and completing a series of tasks.
