Box lateral side protecting device of LED curtain wall screen

Abstract

The invention discloses a box lateral side protecting device of an LED curtain wall screen. The box lateral side protecting device comprises a box, LED lamp beads mounted on the surface of the box, a retaining plate and a pull rod, a containing groove is formed in the side wall of the box, the retaining plate is movably mounted in the containing groove, an elastic element is arranged between the retaining plate and the containing groove and used for providing a force pushing the retaining plate to a direction away from the box, the pull rod is provided with a handle portion, one end, away from the handle portion, of the pull rod penetrates the box to be hinged on the retaining plate, and a limiting face matched with the handle portion of the pull rod is arranged on the box and used for preventing the pull rod from retracting into the box. The retaining plate capable of being movably mounted on the lateral side of the box is arranged on the lateral side of the box, so that when the box is demounted from the curtain wall screen, the retaining plate slides out of the containing groove and retains on the lateral side of the box, and effect of protecting the LED lamp beads is realized; when the curtain wall screen is assembled, the retaining plate is hidden in the containing groove and does not affect flatness of the lateral side of the box, so that assembling of the curtain wall screen is not affected.

Description

[0001] technical field [0002] The invention relates to the improvement of the box body structure of the LED curtain wall screen, in particular to a side protection device of the box body of the LED curtain wall screen. [0003] Background technique [0004] The LED curtain wall screen is composed of LED dot matrix. It displays text, pictures, animations and videos by turning on and off the red, green and blue LED lamp beads. The content can be replaced at any time. All components are modular display devices. When in use, each module is assembled and spliced ​​to achieve a predetermined display effect. Now the LED curtain wall screen industry is developing in the direction of smaller dot spacing. The smaller the dot spacing, the more fragile the LED lamp beads, the smaller the distance between the LED lamp beads and the edge of the box, and the smaller the LED lamp beads on the side. It is easy to be damaged, especially in the process of leasing the LED curtain wall displ...

Problems solved by technology

Now the LED curtain wall screen industry is developing in the direction of smaller dot spacing. The smaller the dot spacing, the more fragile the LED lamp beads, the smaller the distance between the LED lamp beads and the edge of the box, and the smaller the LED lamp beads on the side. Easy to damage, especially in the process of leasing the LED curtain wall display, it is often necessary to disassemble and assemble. During the process of handling and transfer, the LED lamp beads on the side of the box are easily damaged by knocking down the adjacent box or other objects
