Description

Technical Field

[0001] The utility model relates to the technical field of display screen protection, in particular to an LED display screen with a protection structure. Background Art

[0002] LED display screen is an electronic display screen composed of LED dot matrix. It changes the screen display content form such as text, animation, picture, video in time by turning on and off red and green light beads. It controls the component display through modular structure, which is mainly divided into display module, control system and power supply system. In order to improve the anti-collision performance of LED display screen, protective structure is usually installed on the display screen.

[0003] According to the LED display screen with a protective structure disclosed on the patent website (authorization announcement CN219180145U), "An LED display screen with a protective structure includes an LED display screen and a protective structure, wherein the protective structure includes two side protection components and a connecting component for fixing the two side protection components, and the two side protection components are respectively arranged on both sides of the LED display screen."

[0004] In view of the above description, the applicant believes that there are the following problems:

[0005] During use of the utility model, the device uses a connecting component to install two side protection components on both sides of the LED display screen, and the elastic supports on the protection components are in advance in contact with the ground, and the impact force is buffered and then transmitted to the protection components, so as to avoid the displacement of the LED display screen after being impacted by external force, thereby achieving a good protection effect on the LED display screen. When tilting backward, the contact plate can be pre-contacted with the ground, and the damping block plays a buffering role. However, in actual use, the device only protects the two sides of the LED display screen through the side protection components, so that when the LED display screen falls, the elastic supports arranged on the sides play a buffering role. However, when the front of the LED display screen is hit by a sharp object, since the display part of the front of the LED display screen is exposed, the display part of the LED display screen is easily damaged, thereby poorly protecting the LED display screen. Therefore, it is necessary to improve an LED display screen with a protective structure. Utility Model Content
