Problems solved by technology
At present, there are no LED modules with both hollow-out and non-hollow structures. When the equipment equipped with LED modules without hollow-out structures is in a windy environment, the LED modules without hollow-out structures have to be removed and reinstalled. Installing LED modules with a hollow structure will obviously consume a lot of manpower and material resources

Embodiment Construction
[0032] Below in conjunction with accompanying drawing and specific embodiment, the present invention will be further described:
[0033] See Figures 3 to 9 , the present invention relates to an LED (Light Emitting Diode, light-emitting diode) display module, and its preferred embodiment includes a housing 31 , several printed circuit boards 33 installed in the housing 31 , a cover 34 and a bottom plate 32 . A plurality of printed circuit boards 33 are evenly spaced along the width direction of the housing 31, and a spacer 331 is formed between every two adjacent printed circuit boards 33. The cover body 34 is fastened on the housing 31, and the bottom plate 32 is movably mounted on the housing 31. The housing 31 is away from the back plate of the cover 34 .
[0034] The cover body 34 defines the same number of through slots 341 as the partitions 331 , and each slot 341 faces the corresponding partition 331 . The back plate of the housing 31 defines the same number of throug...

A light-emitting diode (LED) display module comprises a casing, a cover body, a base board and a plurality of printed circuit boards installed in the casing. The plurality of printed circuit boards are distributed along the same direction at intervals. An interval portion is formed between every two adjacent printed circuit boards. The cover body is fastened on the casing and is provided with first through grooves identical with the interval portions in number, each first through groove right faces the corresponding interval portion, second through grooves identical with the interval portions in number are arranged on a back board of the casing, and each second through groove right faces the corresponding interval portion. The base board is provided with at least two third through grooves, the interval between the two adjacent third through grooves is no smaller than the width of the second through grooves, the base board is movably installed on the back board of the casing far away from the cover body to selectively enable each third through groove to be aligned at one second through groove, or enable each third through groove to be staggered with the second through groove. The LED display module selectively achieves a hollow structure and a non-hollow structure according to different requirements, is convenient to use and can save cost.
Description
[0001] technical field [0002] The invention relates to an LED display module. [0003] Background technique [0004] Existing LED (Light Emitting Diode, light-emitting diode) display modules can be divided into two types of hollow structures and no hollow structures. Such as figure 1 As shown, for an LED module without a hollow structure, several LED displays are closely spliced, and neither light nor wind can penetrate; figure 2 As shown, for the LED module with a hollow structure, several strip-shaped through grooves 21 are provided on the LED module to reduce the resistance of the screen body to the wind force and prevent damage to the screen body or the installation frame when the wind force is too strong. At present, there are no LED modules with both hollow-out and non-hollow structures. When the equipment equipped with LED modules without hollow-out structures is in a windy environment, the LED modules without hollow-out structures have to be removed and reinsta...
