Description

Technical Field

[0001] This utility model relates to the field of electrical equipment installation, and in particular to a cabinet tensioning device. Background Technology

[0002] During the installation of equipment such as electrical cabinets, network cabinets, and nine-fold profile cabinets, it is usually necessary to connect multiple cabinets side by side (i.e., "paneling") to ensure the stability and sealing of the overall structure. Traditional methods of connecting cabinets mainly use bolts for direct rigid fixing or simple connecting plates for locking. This rigid connection method has poor adaptability, insufficient structural stability, and low installation efficiency. Utility Model Content

[0003] In view of the above situation and to overcome the defects of the prior art, the purpose of this utility model is to provide a cabinet tensioning device, which has the advantages of solving the problems mentioned in the background art.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution: A cabinet tensioning device includes a main frame formed by bending a metal plate. The main frame includes a horizontal connecting part and a vertical folded edge part. The horizontal connecting part has symmetrical stepped bending slots at both ends. Each stepped bending slot includes a first bending segment and a second bending segment. The end of the first bending segment has a guide slope. The step height of the stepped bending slot matches the mounting holes of the cabinet profile. The vertical folded edge part has a Y-direction positioning folded edge, which forms an L-shaped structure with the horizontal connecting part. The main frame has tensioning screw holes and auxiliary screw holes in the middle. The tensioning screw holes are elongated oval holes. The end of the vertical folded edge part has a mounting positioning hole for fixing the relative position of the device and the cabinet.

[0005] By adopting the above technical solution, the main frame (horizontal connection part + vertical folded edge part) formed by bending metal plate provides the main support structure, which has high structural strength and low manufacturing cost. The step bending bayonet achieves rapid positioning and installation through the step height difference and guide slope, improving installation efficiency. The elongated hole tightening screw hole allows for fine adjustment of bolt position, compensates for installation tolerances, and adapts to different tolerances.

[0006] Further details: The angle between the Y-direction positioning fold and the horizontal connecting part is 85°-95°, and the inner side of the Y-direction positioning fold is provided with reinforcing ribs.

[0007] By adopting the above technical solution, the 85°-95° ​​bending angle ensures vertical positioning accuracy, and the inner reinforcing ribs enhance the resistance to deformation.

[0008] Further configuration: The surface of the main frame is provided with anti-slip texture, which covers the upper surface of the horizontal connecting part and the outer side of the vertical folded edge part.

[0009] By adopting the above technical solutions, the anti-slip texture design can increase the surface friction coefficient and extend the tool's service life.

[0010] Further configuration: Wear-resistant pads are fixed to the surfaces of both the first and second bending sections.

[0011] By adopting the above technical solution, the wear-resistant pad covers the contact surface of the bending section, reducing the insertion resistance.

[0012] Further feature: The vertical folded edge of the main frame is provided with an elastic buffer sheet.

[0013] By adopting the above technical solution, elastic support is provided through the pre-compression deformation of the elastic buffer sheet, thereby reducing vibration transmission.

[0014] Further feature: A sealing gasket is fixed to the bottom of the vertical folded edge of the main frame.

[0015] By adopting the above technical solution, the sealing effect and sealing compatibility can be improved through the sealing gasket.

[0016] In summary, this utility model has the following beneficial effects: This utility model adopts an integrated metal plate bending main frame combined with a unique stepped bending bayonet design, which not only improves installation efficiency, but also achieves multi-dimensional tolerance self-adaptation through stepped height difference and guide slope; the combination structure of 85°-95° ​​Y-direction positioning folded edge and reinforcing rib ensures high-precision positioning in the vertical direction, while improving bending strength; the design of elongated hole tension screw hole provides adjustment margin, perfectly compensating for cabinet processing errors; the combination of surface anti-slip texture and wear-resistant pad ensures installation stability and withstands the durability test of plugging and unplugging; the introduction of elastic buffer plate gives the device flexible compensation capability and reduces vibration transmission rate. This technical solution is significantly superior to traditional connection methods in terms of tolerance compatibility, installation efficiency, structural stability and long-term reliability, and is particularly suitable for electrical cabinet paralleling scenarios that require frequent disassembly and assembly or high-precision docking.
