Description

Technical Field

[0001] The utility model relates to the technical field of LED display screens, and particularly relates to an LED display screen cabinet with a solder-free door frame. Background Technique

[0002] An LED display screen (LED Panel) is a display method that controls semiconductor light-emitting diodes. Generally, it consists of many light-emitting diodes, usually red, and shows characters by the lighting and extinguishing of the lights. It is a display screen used to display various information such as text, graphics, images, animations, market conditions, videos, and video signals. LED display screens have been widely used in people's daily lives. They can be seen in shopping malls, office buildings, and outdoor advertisements. LED display screens are usually made into a box structure, and the LED display modules for emitting light are installed on the box. As the smallest display screen unit, multiple boxes can be assembled to form LED display screens of different sizes. In the prior art, the splicing between boxes is carried out by ordinary bolt connections, which are cumbersome and difficult to install, and it is difficult to install, disassemble, and repair the boxes.

[0003] After retrieval, Chinese Patent Publication (Announcement) No. CN203465906U discloses an LED display screen cabinet. The guide rail of one box is inserted into the dovetail groove of another box for connection, and fixed pins or bolts are used for reinforcement, which can achieve quick installation and disassembly. At the same time, the connection between boxes is firm. Convex parts and concave parts are added at the upper and lower ends of the box. Although the above patent solves the problem of cumbersome and difficult installation connection by bolt connection between boxes, the connection between a single box and the screen is not convenient for maintenance, so a connection cylinder needs to be added, and a concave seat also needs to be added, which is convenient for adjusting its angle to a certain extent. Therefore, it is necessary to design an LED display screen cabinet with a solder-free door frame. Content of the Utility Model

A threaded hole is formed in the upper surface of the limiting seat 5, and a screw 6 is threadedly connected to the inner side wall of the threaded hole. A fixing seat is fixedly connected to the back surface of the screen 2, a through hole is formed in the back surface of the fixing seat, and a connecting column is fixedly connected to the back surface of the screen 2.

[0025] During specific use, the connecting column on the back surface of the screen 2 is inserted into the connecting cylinder 3. At this time, the spring provides a certain elastic support, making it have a certain resistance to maintain the stability of the connection. Then, the screw 6 is screwed inward and screwed into the through hole formed in the fixing seat through the threaded hole on the limiting seat 5 to fix the screen 2. When performing maintenance and disassembly, the screw 6 is screwed out.

[0026] In this embodiment, a concave seat 7 is fixedly connected to the back surface of the box body 1, and a damping stud 8 is threadedly connected to one side of the concave seat 7.

[0027] During specific use, the damping stud 8 facilitates positioning the limiting column 9 in the concave seat 7 to make it more stable.

[0028] In this embodiment, a limiting column 9 is fixedly connected to the outer surface of the damping stud 8, and an adjusting cylinder 10 is fixedly connected to the back surface of the limiting column 9.

[0029] During specific use, the angle can be adjusted through the damping stud 8 to make it more flexible.

[0030] In this embodiment, a positioning column 11 is threadedly connected to one side of the adjusting cylinder 10, and an adjusting column 12 is movably connected to the back surface of the adjusting cylinder 10.

[0031] During specific use, the adjusting column 12 moves in the adjusting cylinder 10 and is adjusted to a suitable position, and is limited by the positioning column 11.

[0032] In this embodiment, a connecting seat 13 is fixedly connected to the back surface of the adjusting column 12, and a threaded cylinder is fixedly connected to the upper surface of the connecting seat 13.
