Description

Technical Field

[0001] The present invention relates to the technical field of cabinet chassis, and particularly to a widened adjustable cabinet chassis. Background Art

[0002] A cabinet is an infrastructure carrier used to centrally accommodate, fix, and protect hardware such as electronic devices, network devices, and servers. It constructs the main structure with a high-strength metal frame (mostly steel or aluminum alloy), and is equipped with detachable door panels, side panels, and a rich set of internal accessories to form a standardized and modular installation space, providing a stable operating environment and orderly management conditions for the devices. Cabinets are widely used and crucial. For example, in a data center, they centrally house devices to ensure the stable processing and storage of data; in a communication base station, they resist harsh environments to protect communication devices; in an enterprise computer room, they integrate resources for easy operation and maintenance; in an industrial site, they resist interference and corrosion to support the operation of the automation system. They are an important infrastructure for the stable operation and efficient management of devices in various fields.

[0003] For example, the publication number is CN214901693U, a widened adjustable cabinet chassis, which relates to the technical field of cabinets. An adjustment component is provided inside the cabinet body. One side bottom of the cabinet body is rotatably connected to a rotating ball, one end of the rotating ball is rotatably connected to a movable rod, and a positioning rod is fixedly installed on one side of the bottom of the movable rod; the movable rod can be rotated at multiple angles through the rotating ball. According to the user's needs, the positioning rod on the movable rod is placed into a suitable notch. Each notch makes the opening angle of the cabinet door different, and the fixing of the cabinet door can be realized, and it is not easy to shake left and right, which is convenient for the staff to operate inside the cabinet body. When it is not necessary to fix the cabinet door, just rotate the movable rod upward and snap it into the buckle to fix it, and it will not easily fall off. The whole process is simple and convenient. Through the adjustment component, the internal space of the cabinet body can be adjusted. According to the user's needs, the baffle can be moved appropriately, and the internal space can be widened or narrowed at will.

[0004] However, although the above technical solution can adjust the internal space of the cabinet, in fact, the size of the cabinet does not change, and the capacity of its cabinet body has not been adjusted. Therefore, the width has not been truly adjustable. At the same time, most existing cabinet chassis achieve heat dissipation by introducing gas from the external environment into the cabinet and exhausting the hot air inside the cabinet. This heat dissipation method will cause the change of heat dissipation effect due to the temperature change in the external environment. When the temperature in the external environment is too high, the temperature of the introduced gas is also high, which will lead to a poor heat dissipation effect, thus affecting the operation of the devices inside the cabinet. And most of the support feet of the existing cabinets are fixedly installed. When the devices in the cabinet are concentrated on the upper part, the center is prone to be relatively high, which is likely to cause the situation of tipping over, and the support stability cannot be guaranteed. Summary of the Invention
