Description

Technical Field

[0001] The utility model relates to the technical field of cabinet fixing devices, and more particularly to a cabinet module fixing device and a cabinet. Background Art

[0002] In the power electronics cabinet, electronic modules need to be charged, and batch-upgraded and downloaded software are required. To achieve these functions and improve efficiency, independent slots are designed in the cabinet according to the size of the modules. The independent slots are equipped with guides and positioning devices, and cooperate with the front quick-fix device on the cabinet to quickly fix the modules, thereby realizing batch operation of the modules.

[0003] Currently, in power electronics cabinets, modular devices are generally fixed to the cabinet using multiple screws. During installation and removal, the screws securing the modules need to be repeatedly tightened and loosened, making the operation cumbersome, time-consuming, and labor-intensive, bringing unnecessary trouble to commissioning and maintenance. Secondly, the screw fixing method requires specially designed components for fixing the modules within the cabinet, which not only increases the number of components but also takes up internal space, reducing space utilization. Finally, some modules on the market are fixed using a male-female plug-in connection method. On-site installation and use often rely on brute force, which has a certain impact on the module itself, greatly reducing the life of the connector and reducing the module's reliability. During production, daily use, and after-sales maintenance, the module needs to be installed, tightened, and disassembled multiple times. Utility Model Content

[0025] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the embodiments described are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0026] See Figure 1 、 Figure 2 、 Figure 4 A cabinet includes a cabinet body 1, a module 2, and a cabinet module fixing device 3. The cabinet body 1 is provided with at least one layer. In this embodiment, four partitions are provided to form five layers. Each layer of the cabinet body 1 is provided with multiple slots 4 adapted to the modules 2. The cabinet module fixing device 3 is arranged corresponding to the slots 4, and the projection of the stopper 12 of the cabinet module fixing device 3 on the slots 4 is located within the slots 4, so that it can fix the cabinet module placed in the slots 4.
