Abstract
Description
Technical Field
[0001] This utility model relates to the field of electrical control cabinet technology, and in particular to an electrical control cabinet base plate with high structural strength, thin and light material and low cost. Background Technology
[0002] The bottom of the electrical control cabinet is generally supported by a frame and enclosed by a single panel. If the bottom surface is large, the support strength in the middle area of the bottom panel will be insufficient, causing deformation. This results in poor flatness and low load-bearing capacity of the bottom panel, posing a safety hazard. To improve the load-bearing capacity of the bottom panel, thicker plates are usually used for reinforcement or corresponding horizontal and vertical supports are set in the middle of the frame as auxiliary support structures. This will increase the weight of the bottom panel and the manufacturing cost. Utility Model Content
[0003] This utility model mainly solves the above-mentioned technical problems; it provides an electrical control cabinet base plate with high structural strength, thin and light material, and low cost.
[0004] To solve the aforementioned technical problems, this utility model mainly adopts the following technical solution: This utility model discloses a base plate for an electrical control cabinet, used to enclose the bottom of the cabinet and support electrical components. The base plate has a hollow structure and is fixed to the bottom frame of the cabinet. The base plate includes an upper plate, a lower plate, and a sealing plate disposed between the upper and lower plates to enclose the sides of the base plate. The upper edge of the sealing plate is fixed to the edge of the upper plate, and the lower edge of the sealing plate is fixed to the edge of the lower plate. The bottom surface of the upper plate has multiple downward-facing, integrally formed upper plate tension holes, and the top surface of the lower plate has multiple upward-facing, integrally formed lower plate tension holes. The upper plate tension holes are connected to the lower plate tension holes. The extension holes correspond one-to-one and abut against each other. The extension holes in the upper plate and the lower plate form a support structure between the upper and lower plates. The bottom surface of the extension holes in the upper plate and the top surface of the extension holes in the lower plate are provided with bottom holes. Rivets or screws are provided in the bottom holes. The upper plate and the lower plate are riveted or screwed together through the bottom holes. Multiple support structures are set between the upper and lower plates of the hollow base plate, which improves the structural strength and pressure bearing capacity of the hollow plate. The extension holes in the upper plate and the lower plate are riveted or screwed together through the bottom holes, which eliminates the plate surface tension caused by punching and welding, ensures the flatness of the plate surface, and prevents the plate surface from deforming.
[0005] Preferably, the sealing plate and the upper plate are integrally formed, with the lower edge of the sealing plate riveted to the edge of the lower plate, and the edge of the upper plate directly formed by U-shaped bending and riveted to the lower plate. The structure is simple and the connection is firm.
[0006] Preferably, the upper plate and the lower plate are thin metal sheets, and the stretching holes in the upper plate and the lower plate are at the same height. Using thin metal sheets reduces the weight of the base plate while ensuring its structural strength.
[0007] Preferably, the upper plate stretching hole and the lower plate stretching hole are frustoconical stretching holes. The frustoconical stretching hole structure can effectively avoid the closed-cell effect that occurs in the vertical sidewall holes during deep stretching, ensuring uniform deformation of the sheet and improving the stability of the forming process.
[0008] Preferably, a rubber sheet is embedded between the bottom surface of the upper plate tension hole and the top surface of the lower plate tension hole to improve the shock absorption performance of the base plate.
[0009] Preferably, the upper plate has multiple downward-facing upper plate reinforcing ribs in the area between adjacent upper plate tension holes, and the lower plate has multiple upward-facing lower plate reinforcing ribs in the area between adjacent lower plate tension holes. The presence of multiple reinforcing ribs on the surfaces of the upper and lower plates can improve the structural strength and load-bearing capacity of the upper and lower plates.
[0010] The beneficial effects of this utility model are as follows: the base plate adopts a hollow structure composed of upper and lower thin plates, and multiple stretching holes set on the surface of the thin plates are riveted or screwed together to form a support structure for the base plate. While ensuring that the material is thin and light, the structural strength and bearing capacity of the base plate are improved. The stretching holes of the upper plate and the stretching holes of the lower plate are riveted or screwed together, which eliminates the plate surface tension caused by stamping and welding, ensures the flatness of the plate surface, and prevents the plate surface from deforming.

[0015] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.
[0016] Example: This example describes a base plate for an electrical control cabinet, used to enclose the bottom of the cabinet and support electrical components, such as... Figure 1 and Figure 2As shown, the base plate 1 has a hollow structure and is fixed to the bottom frame 2 of the electrical control cabinet. The base plate includes an upper plate 11, a lower plate 12, and a sealing plate 13 located between the upper and lower plates to close the sides of the base plate. The upper and lower plates are 2mm thin metal sheets. The sealing plate is formed by U-shaped bending of the upper plate. The lower edge of the sealing plate is riveted to the edge of the lower plate. The bottom surface of the upper plate has multiple downward-facing upper plate tension holes 14, and the top surface of the lower plate has multiple upward-facing lower plate tension holes 15. The tension holes of the upper plate and the tension holes of the lower plate are connected in a straight line. The upper and lower plate tension holes are truncated cones of equal height and correspond to each other. The upper and lower plate tension holes form a support structure between the upper and lower plates. The bottom surface of the upper plate tension hole and the top surface of the lower plate tension hole are designed with bottom holes, and rivets 16 are installed in the bottom holes. The upper and lower plates are riveted and fixed through the bottom holes. The upper plate has multiple downward-facing upper plate reinforcing ribs in the area between adjacent upper plate tension holes, and the lower plate has multiple upward-facing lower reinforcing ribs in the area between adjacent lower plate tension holes.
[0017] The hollow base plate, formed by the upper and lower plate structures of thin metal sheets and the abutment support of the tension holes, allows for flexible installation of support structures at appropriate locations according to load-bearing requirements. While ensuring the base plate is thin and lightweight, it improves the structural strength and load-bearing capacity of the base plate. The connection between the tension hole support structure and the sealing plate is made by riveting, which eliminates the tension on the plate surface caused by stamping and welding, ensuring the flatness of the plate surface and preventing deformation.
