Description

Structure of data cabinet

Technical Field

The invention relates to the technical field of cabinets, in particular to a structure of a data cabinet.

Background

The common data cabinet in the market at present generally adopts a cabinet frame which is assembled by assembling and welding a front frame ring and a rear frame ring and then fixedly assembling the front frame ring and the rear frame ring and a side cross beam by adopting screws, the front frame ring and the rear frame ring are in plane contact without any buckle or limiting device, and the cabinet frame structure assembled by adopting the method has low bearing capacity and poor side stability; when the device is used for a cold and hot channel, in order to avoid cold air leakage, an additional accessory seal is required to be added; when the front end is wired, a wire groove and the like are additionally added for wire arrangement for the sake of attractiveness; when the cable passes through the cable, some cables are fastened by screws and covered by steel plates after the cable holes are directly formed in the steel plates, the cables can be operated by tools when the cable passes through the cable holes, and the steel plates cannot well protect the surfaces of the cables from being scratched even though the steel plates are subjected to plastic spraying and other treatment; the plastic wire passing hole covers are added on the steel plates for protection, but the size of the wire passing holes is generally inconvenient for drilling and needs tools; in addition, the hair brush hole covers are adopted on a plurality of wire passing holes, so that air leakage cannot be effectively prevented; when heavy equipment such as a server and the like in a cabinet is installed, in order to meet the bearing requirements of the server, a method of increasing the thickness of a supporting piece is often adopted, so that the cost of the cabinet and the weight of the whole cabinet need to be increased; when the cabinets are installed in a combined mode, the cabinets cannot be combined with side doors or the cabinet combination needs to be changed into a customized side door structure, and the universality is low; in a cabinet with multiple cabinets, if a middle cabinet needs to be replaced integrally, the cabinet needs to be replaced with a large labor cost.
