Description

Technical Field

[0001] The utility model relates to the technical field of LED display screens, in particular to a wall-mounted LED screen terminal. Background Art

[0002] In the prior art, LED display screens are widely used in various indication, display, decoration, backlight sources, general lighting, and city night scenes due to their excellent color performance, high brightness, good energy saving, and ability to achieve large-size seamless splicing. When the LED display screen is in use, it is necessary to hang the LED display screen on the wall.

[0003] After searching, the Chinese patent application number 202320434863.4 discloses a wall-mounted LED screen terminal, including an LED screen, the back of which is fixedly connected to a host, the top of the host is movably mounted on two groups of buckles by two groups of first screws, and the insides of the two groups of buckles are provided with slide grooves, and the buckles are slidably connected to the bracket through the slide grooves and the sliders, and the two ends of the bracket are provided with slots, and the two ends of the bracket are slidably connected to the fixed frame through the slots, and the side of the fixed frame close to the LED screen is fixedly connected to the chassis, and the LED screen and the host are fixed to the buckles by screws, so that their positions can be firmly fixed with high stability; in the wall-mounted LED screen terminal, the two ends of the bracket are fixedly connected to the first limit blocks, and the sliders are fixedly connected between the two groups of the first limit blocks, so that the range of left and right movement of the LED screen driven by the buckles can be limited by the limit blocks at both ends of the bracket.

[0004] The above patent has the following deficiencies: the device can adjust the position of the LED screen on the wall left and right by linking the slide groove on the buckle with the slider on the bracket, and realizes the lifting function of the LED screen under the drive of the motor by passing the threaded rod through the threaded hole; however, in actual use, the device can only adjust the position in the downward and left and right directions, and cannot adjust the forward tilt angle. When the LED screen is raised to a certain height, the farther the distance is, the smaller the head-up angle will be, but the head-up angle will increase for people who are close, which is not conducive to viewing the LED screen.
