Description

Technical Field

[0001] This utility model relates to the technical field of nine-fold profile cabinets, and in particular to the technical field of side cabinet door installation structure. Background Technology

[0002] In recent years, folding profile cabinets have been widely used in various electrical fields such as power systems and automation control due to their excellent mechanical properties and spatial adaptability. However, in the actual assembly process, factors such as insufficient precision of the nut column bracket, deformation of the frame welding, misalignment of the foam adhesive application position on the cabinet door, and deviation in the adhesive application height control often lead to poor contact between the foam adhesive and the cabinet frame. This not only weakens the sealing performance of the cabinet door and the overall structural strength, but may also cause risks such as a decrease in protection level and moisture in electrical components, affecting the reliability and service life of the equipment.

[0003] The current common solution is to increase the cross-sectional size of the foam on the side cabinet door to compensate for the welding error of the frame and the error of the glue application position. However, due to the characteristics of the foam itself, the cross-sectional size of the glue strip can only be increased slightly, and the protective performance cannot be fundamentally solved. As a result, the problem of low pass rate of protection of the side cabinet door has always existed. Summary of the Invention

[0004] The purpose of this utility model is to solve the problems in the prior art by proposing a high-protection-level reliable installation structure for the side cabinet door of a nine-fold profile cabinet, which can solve the above problems.

[0005] To achieve the above objectives, this utility model proposes a high-protection-level reliable installation structure for the side door of a nine-fold profile cabinet, including a fixed bracket, a profile frame, and a side door. The fixed bracket is installed inside the profile frame, and the fixed bracket includes a fixed plate, a mounting plate, and a limiting plate. The mounting plate is located on the side of the fixed plate away from the profile frame, and the limiting plate is located on the side of the mounting plate away from the fixed plate. The mounting plate has mounting holes, and the limiting plate has clearance space at positions matching the mounting holes. The side door has an opening coaxially aligned with the mounting holes. A sealing strip is provided on the inner side of the side door, and the inner surface of the side door abuts against the limiting plate. A frame is provided on the profile frame, and the sealing strip abuts against the frame frame. The fixed bracket is installed on the outer edge of the frame frame.

[0006] Preferably, the four corners of the skeleton frame are notched, and skeleton compensation components are fixed at the notched corners.

[0007] Preferably, the outer surface of the profile skeleton is flush with the outer surface of the skeleton frame.

[0008] Preferably, the fixing plate is connected to a connecting plate, the connecting plate is connected to a side plate, the side plate is provided with limiting plates on both sides, the clearance space is located between the two limiting plates, and the side plate is provided with a mounting plate in the middle. The connecting plate, side plate, fixing plate, mounting plate and limiting plate are sheet metal parts formed by bending.

[0009] Preferably, the fixing plate, mounting plate, and limiting plate are disposed on the same side of the side plate and are parallel to each other.

[0010] Preferably, a first press-fit nut is provided at the mounting hole, and fixing holes are provided on both sides of the fixing plate, with a second press-fit nut provided at the fixing hole.

[0011] Preferably, the connecting plate is inclined to the fixing plate.

[0012] Preferably, the mounting hole protrudes from the limiting plate, and the mounting plate is located inside the skeleton frame.

[0013] The beneficial effects of this utility model are:

[0014] 1. This utility model uses a fixed bracket to replace the original nut column bracket of the nine-fold profile cabinet. The fixed bracket plays a limiting role in the compression of the door panel rubber strip.

[0015] 2. In this utility model, the opening position of the side door panel of the nine-fold profile frame is set close to the edge of the frame, so that the door rubber strip and the frame frame can fully overlap after the cabinet door is installed, thereby improving the reliability of protection.

[0016] 3. This utility model increases the overlap area between the frame frame and the cabinet door rubber strip at the corners by welding the frame compensation parts to the four missing corners of the frame frame, thereby improving the reliability of protection.

[0017] 4. The fixed bracket of this utility model can be riveted by hot-dip galvanized sheet and riveting nut bending machine, which eliminates the need for machining of the currently common nut column bracket and greatly improves the machinability.

[0018] The features and advantages of this utility model will be described in detail through embodiments and accompanying drawings. Attached Figure Description
