Anti-external force impact swing connection LED lamp panel applied to cinema

Abstract

The invention discloses an anti-external force impact swing connection LED lamp panel applied to a cinema. The LED lamp panel structurally comprises swing connection heads, a box body, and a display end; and the swing connection heads are connected with the outer surface of the box body. Under the pushing of external force, swing connection rods can swing at a certain angle; return swing openingswhich are originally connected and clamped together are staggered; certain buffer force is obtained; the return swing openings are pushed to return; when inner abutting cores of the return swing openings swing up and down in a certain range, buffer roll balls generate certain deformation due to the external force and move to the two sides; squeezed points are recessed; outer supporting curved layers are pushed by certain force; while outer soft layers are squeezed to be deformed, inner arc angles are expanded for returning and protecting the outer soft layers, so that the inner abutting coresof the return swing openings can be returned; and when connection ends are staggered, the connection ends can be returned by certain counter force while the connection ends are staggered and buffered,so that the connection ends can be returned in time.

Description

technical field [0001] The invention belongs to the field of LED display screens, and more specifically relates to a connecting LED light board used in theaters to prevent external impact and swing. Background technique [0002] In order to achieve a better effect in the max hall of the theater, the surrounding walls have certain elasticity and softness. Due to the softness of the walls, the unit boards of the display screen need to be separated from the walls by a certain distance, so It will be affected by its vibration to produce displacement and deformation. When the movie is over, the screen will be in a dark state. When a child is running in the courtyard, the screen will be slapped. [0003] Based on the discovery of the above inventors, the existing LED light panels in cinemas mainly have the following deficiencies, such as: [0004] Since the screen is spliced ​​by many unit boards, there will be a certain displacement and sunken dislocation. When the screen is not...

AI Technical Summary

Problems solved by technology

[0006] In order to solve the above technology, since the screen is spliced ​​by many unit boards, there will be a certain displacement and sunken dislocation. When the screen is not lit, a little bit of dislocation and poor connection prevent the staff from seeing the problem in time. , which will cause problems affecting its playback effect after its opening
