Description

Technical Field

[0001] The utility model relates to an improvement of an auxiliary device of an LED screen, in particular to an improvement of a waterproof and rainproof rear shell of an LED unit board module. Background Art

[0002] The current large-scale LED display screens are assembled from multiple LED unit board modules. Each LED unit board module is composed of exactly the same modules. The entire display screen is assembled by selecting a corresponding number of LED unit board modules according to the site requirements and the actual application scenario size. This facilitates transportation and installation and greatly reduces the production, transportation, installation and use costs of large LED screens.

[0003] The current LED unit board module is generally composed of a display panel and a main shell. A through hole is set in the middle of the main shell for passing the circuit. A plurality of magnetic columns are set on the main shell. Since the through hole may allow rain to enter and water to leak, a cover plate is often set on the through hole for rain and water protection. However, the waterproof and rainproof effects of these end covers on the current market are very limited, and the installation of such cover plates is relatively complicated and the sealing performance is also poor, making it difficult to truly protect the display panel and the panel's circuit board. Utility Model Content

[0004] The purpose of the utility model is to provide a waterproof and rainproof rear shell of an LED unit board module in view of the defects and shortcomings of the prior art. The utility model has a simple and quick plug-in method, good waterproof and rainproof performance, can provide good protection for display panels and circuit boards, and can also be more convenient in the transportation, installation and use of large LED screens.

[0005] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: it includes a main shell 1, a plurality of through holes 11 are provided on the main shell 1, a waterproof cover 2 is clamped on the through hole 11, and a plurality of magnetic column holes 12 are provided on the periphery of the main shell 1; an extended outer folded edge 111 pointing to the back direction of the main shell is provided on the periphery of the through hole 11, an inner folded edge 112 is provided inside the outer folded edge 111, a wiring harness opening 113 is provided on one side of the outer folded edge 111 and the inner folded edge 112, and a plurality of clamping grooves 114 are provided on the inner wall of the through hole 11; the waterproof cover 2 has a vertical folded edge 21 at its edge, a wiring harness opening 211 is provided on one side of the vertical folded edge 21, and the wiring harness opening 211 corresponds to the wiring harness opening 113; a plurality of buckles 22 are provided on the inner side of the waterproof cover 2, and the buckles are perpendicular to the end face of the waterproof cover 2.

[0006] The wiring harness opening 211 of the waterproof cover 2 is provided with an outwardly extending edge 2111. The provision of the extending edge 2111 can make the wiring harness opening 211 extend outwardly, and the wiring harness passes through the opening more steadily and smoothly.

[0007] The snap-fitting groove 114 corresponds to the position of the snap-fitting buckle 22. The snap-fitting buckle 22 is snap-fitted into the snap-fitting groove 114, so that the snap-fitting effect of the snap-fitting buckle 22 can be ensured.

[0008] The working principle of the utility model: when in use, the LED panel is fixedly mounted on the front of the main housing 1, and the waterproof cover 2 is connected to the back of the main housing 1 and snapped. The number of waterproof covers 2 corresponds to the number of through holes 11, and the number of through holes 11 is determined according to the number of wiring harnesses, and can also be preset. The waterproof cover 2 covers the extended fold 111 and is snapped with the snap groove 114 through the snap 22. The wiring harness of the circuit board passes through the wiring harness opening 211 to ensure the stability and sealing of the snap connection; it can achieve good waterproof and rainproof effects. When disassembly is required, it is only necessary to apply external force to disengage the snap 22.

[0009] After adopting the above technical scheme, the beneficial effects of the utility model are as follows: it adopts card-connection, which makes installation and disassembly convenient and quick. Since the cover-type waterproof cover 2 is adopted, it can have good rainproof and waterproof effects, can play a good protective role for the LED unit board module and the circuit board, and can also be more convenient in the transportation, installation and use of large LED screens.
