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 testing 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 a long time.

[0003] In the prior art, the patent document with the announcement number CN 213731614 U discloses a test stand for an LED display desktop device with an adjustable angle, including: a support frame and a base frame hinged to each other, the number of the support frame and the base frame is set to two, a support rod is provided between the support frame and the base frame, the support frame is provided with at least one first support groove, the base frame is provided with a second support groove corresponding to the first support groove, and the support rod abuts against the first support groove and the second support groove respectively. The support rod abuts against the first support groove and the second support groove respectively, which can tighten the support frame and the base frame, thereby facilitating the support of the LED display desktop device. By abutting the support rod against the first support groove and the second support groove at different positions, the support angle of the LED display desktop device can be adjusted. The angle adjustment of the above scheme cannot be completely adjusted to a vertical ground state, and the support structure is unstable and occupies a large area. It can only be used for testing small display screens, and is not suitable for testing large display screen cabinets after assembly and splicing. Utility Model Content
