Description
Technical Field
[0001] This utility model relates to the field of low-voltage switchgear assembly technology, and more specifically, to a connection structure between the crossbeams and columns of a cabinet frame. Background Technology
[0002] In traditional low-voltage switchgear assemblies, the pressure plate connecting the crossbeam and the column is typically made of 8mm thick steel plate through cutting and machining. This traditional manufacturing process has the following problems:
[0003] 1. Material waste: Using thick steel plates and cutting them will generate a lot of waste, resulting in a waste of material costs.
[0004] 2. High processing cost: It requires the use of thick steel plates for cutting, the processing process is complicated, and the equipment consumes a lot of energy.
[0005] 3. Difficulty in precision control: Due to the limitations of the processing methods, it is difficult to achieve high precision during the hole fitting process, which may lead to errors during assembly.
[0006] 4. Complex post-processing: The steel plates after cutting and processing need to be galvanized to prevent corrosion, which adds extra processing steps and costs. Utility Model Content
[0007] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a connection structure between the crossbeams and columns of a cabinet frame.
[0008] To solve the above problems, the present invention adopts the following technical solution:
[0009] A connection structure for a cabinet frame beam and uprights includes a connecting plate for connecting the beam and the uprights. The connecting plate is formed by stamping and has a groove on its surface. A pull-up hole is provided on the connecting plate in the middle of the groove. Two round holes and two bosses are provided diagonally at the four corners of the connecting plate. The connecting plate is connected to the beam at the middle pull-up hole by bolts. The uprights are held between the connecting plate and the beam.
[0010] As a further description of the above technical solution: the diameter of the circular hole is 5.5mm, which is used to fix the column to the crossbeam with the help of the M6 high-strength self-extruding screw connecting pressure plate.
[0011] As a further description of the above technical solution: the pull-up hole is a threaded hole with a diameter of 10mm.
[0012] As a further description of the above technical solution: the connecting plate is a square plate, and the four corners of the connecting plate are rounded.
[0013] Compared with existing technologies, the advantages of this utility model are:
[0014] I. This solution provides a connection structure between the cabinet frame beams and columns. This structure significantly improves the stability and structural strength of the cabinet frame by using a connecting pressure plate design. The connecting pressure plate is formed by stamping and has high precision and strength, greatly improving production efficiency while reducing material waste.
[0015] Second, this solution provides a method to connect the beam to the connecting plate using bolts through the pull-up hole in the middle of the connecting plate, and to clamp the column between the connecting plate and the beam. By locking the connecting plate, a stable connection between the beam and the column is achieved, which simplifies the installation process and makes it easy to disassemble when needed, providing greater flexibility and maintainability.
[0016] Third, the precise hole fitting and designed boss make the connection between the beam and the column more secure and accurate, simplifying the installation process and improving assembly efficiency. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0023] Please see Figure 1-3A connection structure for a cabinet frame beam and uprights includes a connecting plate 1, which is made of galvanized steel sheet. The connecting plate 1 is used to connect the beam 2 and the uprights 3. The connecting plate 1 is formed by stamping, which allows for precise control of the plate's size and shape, thereby maximizing the use of raw materials. The surface of the connecting plate 1 has a groove 11, and a pull-up hole 12 is provided on the connecting plate 1 at the center of the groove 11. Two round holes 13 and two bosses 14 are provided diagonally at the four corners of the connecting plate 1. The connecting plate 1 is connected to the beam 2 by bolts at the middle pull-up hole 12, and the uprights 3 are secured between the connecting plate 1 and the beam 2.
[0024] This design optimizes the connection structure of the connecting pressure plate using a one-time stamping process, simplifying manufacturing while ensuring dimensional accuracy and repeatability. It also provides sufficient strength and rigidity to withstand heavy loads. The connecting pressure plate 1 is bolted to the crossbeam 2, and the column 3 is secured between the connecting pressure plate 1 and the crossbeam 2. Locking the connecting pressure plate 1 further secures the crossbeam 2 and column 3, simplifying the installation process and allowing for easy disassembly when needed, providing greater flexibility and maintainability.
[0025] In addition, the diameter of the round hole 13 is 5.5mm. The round hole 13 is used to assist the connection plate 1 in fixing the column 3 to the crossbeam 2 through the M6 high-strength self-extruding screw, increasing the stability of the connection. The pull hole 12 is a threaded hole with a diameter of 10mm that mates with an M10mm bolt. The connection plate 1 is a square plate with rounded corners, reducing the risk of damage caused by sharp corners. In addition, since the connection plate 1 is made of aluminized zinc steel plate and is stamped in one piece by a stamping die, the surface of the part is smooth and does not require subsequent anti-corrosion treatment such as spraying or electroplating, simplifying the production process.
[0026] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
