Technical Field

[0001] The utility model relates to the technical field of rail transit control cabinets, in particular to a fan disk assembly fixture structure of a rail transit cabinet. Background Art

[0002] During the assembly of fan trays in existing rail transit cabinets, for the fan and cover to be assembled smoothly, at least two of the four cover mounting holes and the four fan screw holes must be roughly aligned with the through holes on the tray body, so that fasteners can be smoothly locked into the fan screw holes. At the same time, due to the presence of the ribs on the tray body, a seesaw structure is formed, which creates difficulties for assembly. In this case, to implement assembly, either the two ends of the ribs on the same side are raised to reserve sufficient space for the fan to enter from the top; or the tray body is placed on its side, requiring at least two people to collaborate and perform assembly from the left and right sides.

[0003] However, regardless of which of the above options is chosen, the alignment of mounting holes, vias, and screw holes on different parts prior to assembly relies entirely on visual matching. Given the strict time constraints of overall production schedule, this process requires a large number of people, is labor-intensive, and inefficient. Clearly, this high production cost is unreasonable and unsustainable.

[0004] In order to solve the above problems, it is urgent to develop a fan tray assembly fixture structure for rail transit cabinets. Utility Model Content

[0005] In response to the shortcomings of the above-mentioned existing production technology, the applicant provides a fan tray assembly fixture structure for a rail transit cabinet, thereby reducing the difficulty of assembly, significantly reducing labor costs, and greatly improving work efficiency and product quality.
