Description

Technical Field

[0001] The utility model belongs to the technical field of screen manufacturing detection, and in particular relates to a display screen box aging test frame. Background Art

[0002] Large-area LED display screens are made up of multiple cabinets. The display cabinet plays an important role in the display screen. It can not only protect the internal components, but also disassemble the LED display screen for easy transportation and maintenance. After the LED display screen is manufactured, the display screen needs to be installed on the cabinet for aging testing to simulate various technical problems that may occur during the use of the test display cabinet, so as to make targeted improvements or eliminate unqualified products. However, the existing display cabinets have a variety of sizes and specifications, and because the assembled display cabinets occupy a large area, if a test frame is made separately for each display cabinet, the testing cost is too high; if a general adjustable test frame is assembled, not only the assembly process is complicated and occupies a large area, but it is also difficult to meet the function of stably supporting a large-area display cabinet group for testing for a long time.

[0003] In the prior art, a patent document with the announcement number CN 115494271 A discloses a display screen aging test stand, which includes a frame body, a partition plate fixedly connected at equal intervals inside the frame body, and also includes: a movable plate, a partition rod, a connecting plate, a connecting shaft and a linkage block. The movable plates are provided with three, and the movable plates are respectively slidably connected to the top of the corresponding partition plates. The top of the movable plates are provided with strip holes at equal intervals. The partition rods are provided with a plurality of partition rods, and the partition rods are respectively arranged above the corresponding movable plates at equal intervals. The above scheme improves the safety and stability of the display screen detection, but it cannot simulate the vertical state of most display screen boxes when in use, and its test effect is not ideal, and it is not suitable for the aging test of large combined display screen boxes.
