The rotation of the driven bevel gear 2112 drives the rotation of the moving roller 22 opposite to the moving roller 22 connected with the driven bevel gear 2112, so that the two moving rollers 22 rotate at the same time. The transmission rod 2113 is used to drive the corresponding moving roller 22 to rotate at the same time, so as to avoid the driving motor 212 driving one moving roller 22 to rotate, so that the drawer 2 moves only on one side, and then the whole drawer 2 moves in a circular arc motion with the rotatable moving roller 22 as the center, causing the guide plate 11 to be stuck with the drawer 2, and the drawer 2 cannot move. It is beneficial to move the drawer 2 on both sides at the same time, reduces the risk of the drawer 2 being stuck, and improves the smoothness of the movement of the drawer 2.

[0035] Further, the drawer 2 comprises a side plate 23, a back plate 24 and a connecting plate 25, the side plate 23, the connecting plate 25 and the back plate 24 are connected to form a rectangular frame, and the back plate 24 is provided with one or more mounting clamping positions 241, and the mounting clamping positions 241 are symmetrically distributed on the back plate 24. In this embodiment, the drawer comprises two side plates 23, one back plate 24 and one connecting plate 25, the connecting plate 25 is used to connect the two side plates 23, the back plate 24 is used to connect the two side plates 25, the back plate 24 is provided with two mounting clamping positions 241, and the two mounting clamping positions 241 are symmetrically distributed on the back plate 24. The mounting clamping position 241 is used to install the corresponding limit switch assembly, and the limit switch assembly is fixedly installed in the mounting clamping position 241, so as to avoid the mis-triggering or failure of the limit switch assembly due to vibration or movement, and reduce the risk of failure of the limit switch assembly.

[0036] Further, the two edges of the mounting clamping position 241 are recessed to form a plurality of clamping grooves 2411, and the roots of the plurality of clamping grooves 2411 are arc-shaped. In this embodiment, the two edges of the mounting clamping position 241 are recessed to form four clamping grooves 2411, the four clamping grooves 2411 are used to fix the electric connecting lines of the limit switch assembly, and the roots of the clamping grooves 2411 are arc-shaped to fit the surface of the electric connecting lines, so as to ensure that the clamping grooves 2411 and the electric connecting lines are tightly fitted, avoid the electric connecting lines from shaking left and right during use, and reduce the risk of collision between the electric connecting lines and other electronic components, heat and energy loss caused by poor contact, and improve the service life of the electronic components inside the drawer 2.

[0037] Further, a plurality of heat dissipation holes 231 are arranged on the side wall, and the plurality of heat dissipation holes 231 are arrayed on the side wall. In this embodiment, two side plates 23 are symmetrically distributed, and twenty-two heat dissipation holes 231 are arranged on each side wall, that is, forty-four heat dissipation holes 231 are arranged on the entire drawer 2, which are used to increase the flow area between the inside of the drawer 2 and the external environment, so as to ensure that air can flow through the inside of the equipment uniformly and smoothly. The forty-four heat dissipation holes 231 form effective convection channels, so that cold air enters the inside of the drawer 2 from the heat dissipation holes 231 on one side plate 23, and then is discharged from the heat dissipation holes 231 on the other side plate 23 after taking away heat in the inside of the drawer 2, thereby accelerating the heat dissipation efficiency in the inside of the drawer 2.

[0038] Further, the upper half of the guide plate 11 extends towards the drawer 2 to form an inclined surface. The inclined surface covers the movement stroke of the corresponding moving roller 22, and the inclined surface and the guide plate 11 cooperatively surround the movement path of the moving roller 22, so as to avoid foreign objects from entering the movement path of the moving roller 22, which causes the moving roller 22 to be unable to move smoothly along the guide plate 11, and is beneficial to protecting the moving roller 22 from moving smoothly along the guide plate 11.

[0039] Further, the bottom of the guide plate 11 extends horizontally to form a fixed plate 112, and a plurality of fixed counterbores are arranged on the fixed plate 112. Five fixed counterbores are arranged on each fixed plate 112, and the five fixed counterbores are linearly and uniformly distributed on the fixed plate 112. The linearly and uniformly distributed counterbores can ensure uniform transmission of the load on the fixed plate 112, thereby improving the stability of the guide plate 11. Meanwhile, the linearly and uniformly distributed counterbores enable the fixed plate 112 to more uniformly distribute stress when bearing the load, thereby enhancing the overall strength of the guide plate 11, and being beneficial to prolonging the service life of the guide plate 11 and reducing the maintenance cost of the guide plate 11.

[0040] Further, a limiting block 111 is arranged on each guide plate 11. In this embodiment, the limiting block 111 has a certain magnetism, and the limiting block 111 is located at the end of the guide plate 11. When the moving roller 22 moves to the limiting block 111, the limiting block 111 has an adsorption force to the magnet 222 on the moving roller 22, so that the moving roller 22 is attached to the limiting block 111, thereby limiting the rolling of the moving roller 22, avoiding the moving roller 22 from moving too long, and causing the drawer 2 to move out of the base 1, which is beneficial to effectively controlling the movement range of the moving part and reducing the drawer 2 from exceeding the safety limit.

[0041] Further, a plurality of heat dissipation grooves 12 are arranged on the base 1, and the plurality of heat dissipation grooves 12 are arrayed in the middle region of the base 1. In this embodiment, seventy-five heat dissipation grooves 12 are arranged on the base 1, and the seventy-five heat dissipation grooves 12 are divided into five columns, each column having fifteen heat dissipation grooves 12, which are arrayed on the base 1, thereby increasing the heat dissipation area of the base 1 and enabling heat to be more quickly conducted to the air through the heat dissipation grooves 12. Meanwhile, the arrayed arrangement ensures the uniformity of heat dissipation and avoids local overheating, which is beneficial to accelerating the heat dissipation efficiency of the base 1. The seventy-five heat dissipation grooves 12 correspond to the bottom of the electronic components installed in the drawer 2, that is, the heat is mainly concentrated in this region, and this is the most critical part of heat dissipation. By arranging the heat dissipation grooves 12 in the middle region, heat can be more effectively conducted from the inside of the base 1 to the outside, thereby improving the heat dissipation efficiency.

[0042] In summary, the transmission mechanism and the moving roller are arranged, the moving roller is rotated to drive the drawer to move along the guide plate, thereby realizing the effect of automatically opening or closing the drawer, reducing the step of manually pushing or pulling the drawer, and improving the intelligence of the high-voltage cabinet. The utility model also has a guide plate, the transmission mechanism drives the moving roller to rotate, the moving roller drives the drawer to move along the guide plate, the drawer moves along the preset path, the step of pulling out by hand and the step of aligning the hole position are reduced, and the intelligence of the high-voltage cabinet is improved. The utility model is provided with a magnet on the moving roller, when the moving roller rotates to the corresponding position, the limiting block has an adsorption force on the magnet, thereby limiting the rolling of the moving roller, avoiding that the moving roller moves too long, causing the drawer to move out of the base, which is beneficial to effectively controlling the movement range of the moving part and reducing the drawer beyond the safety limit.

[0043] In addition, the structure of the electric drawer is described in detail, and the principle and implementation mode of the utility model are described by using specific examples. The above description of the embodiments is only used to help understand the method and core idea of the utility model.
