Description

Technical Field

[0001] The invention relates to the technical field of industrial computer installation, and in particular to a multifunctional modular bracket which is convenient for wiring and maintenance. Background Art

[0002] In industrial automation control systems, industrial computers are an important type of computer equipment used to monitor and control machinery and equipment, production processes, and data parameters used in the production process. In actual applications, industrial computers often need to be connected to other devices through multiple wiring harnesses.

[0003] Chinese patent CN219928502U discloses an industrial computer storage rack, including a storage rack body, a sealing rack, a moving assembly, a driving assembly and a pushing assembly. The industrial computer storage rack pushes the sealing rack to move and separate from the storage rack body through the moving assembly, and pushes the industrial computer equipment to a fixed position under the action of the pushing assembly to realize the storage of the industrial computer. However, in actual use, due to the high degree of customization of industrial computers, different users have different requirements for the number of industrial computers. The fixed capacity storage rack not only occupies a large space, but also may affect the heat dissipation performance of the industrial computer.

[0004] During the use of industrial computers, it may be necessary to install expansion devices in the chassis due to changes in customer needs, or its components may need to be repaired and maintained during long-term use. Industrial computers are often fixedly installed on the fixed panel or pull-out panel of the cabinet;

[0005] For an industrial computer on a fixed panel, the operator needs to remove the fixed panel before operating the chassis; for an industrial computer on a pull-out panel, the operator needs to pull out the entire industrial computer for inspection. However, the pull-out structure of the pull-out panel has a small load, and the operator cannot exert a large downward pressure on the industrial computer when operating the industrial computer. It is inconvenient to operate the industrial computer under the above two working conditions.

[0006] Based on this, the present invention designs a multifunctional modular bracket that is convenient for wiring and maintenance to solve the above problems. Summary of the invention
