Description

Technical Field

[0001] The utility model relates to the technical field of LED screen connection, in particular to a LED screen fixing structure. Background Art

[0002] LED screen, or light-emitting diode display, is a new type of display device made by arranging light-emitting diodes (LEDs). With its excellent performance and wide range of application scenarios, LED screen has become an important part of modern display technology and is widely used in commercial advertising, information display and other fields.

[0003] LED screens have the characteristics of low heat generation, high safety and greater environmental protection, and can be selected in different sizes and shapes according to the needs of use. From small road signs to large exterior wall commercial advertisements, all can be completed by LED screens.

[0004] During the setting process of the LED screen, the size of the required screen is generally determined first, and then the frame and mounting frame are set according to the size of the required screen. Then the LED screen modules are fixed to the mounting frame one by one through magnets, and the LED screen is installed and fixed within the frame.

[0005] However, during use, since magnets are used for connection and fixation, more magnets will be used. Although the installation will be more convenient, the long-term influence of the magnetic field of the magnets will affect the stability of the LED screen and its connected electronic components, which is not conducive to the long-term use of the LED screen and brings inconvenience;

[0006] Moreover, magnets easily absorb the surrounding magnetic particles, which will accumulate on the back of the LED screen over time, and will also affect the long-term use of the LED screen. Utility Model Content

DETAILED DESCRIPTION

[0038] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0039] In the examples of this application, please refer to Figure 1 and 2 A LED screen fixing structure includes an outer frame 10 and a fixing frame 11 fixed therein. The outer frame 10 and the fixing frame 11 are both mounting outer frame fixing frames of existing LED screens, and are used to install a screen module 20. The screen module 20 refers to an existing LED screen module, and any existing one is sufficient.

[0040] A fixing plate 30 is fixed to the back of the screen module 20. A plurality of through holes are provided inside the fixing plate 30 for connecting the circuits of the screen module 20. Connecting seats 40 are provided at the four corners of the fixing plate 30. The connecting seats 40 are connected to a stabilizing plate 50. The stabilizing plate 50 abuts against a fixing frame 11. The fixing frame 11 is composed of a plurality of rods. The edges of the rods are smooth. An inclined surface is provided at one end of the stabilizing plate 50 away from the screen module 20, and a rough surface is provided on the side abutting against the fixing frame 11. When in use, the screen module 20 Figure 2 As shown, four stabilizing plates 50 and a connecting seat 40 are installed on the fixing frame 11, and magnets are no longer used. This not only simplifies the operation, but also avoids the adverse effects of magnets, and is more convenient for long-term use of the LED screen.

[0041] For further information, see Figure 1 , 2 3. The connecting seat 40 includes a mounting seat 41 placed in contact with the fixing plate 30. The mounting seat 41 is fixed to the fixing plate 30 by screws 42. The screws 42 are threadedly connected to the fixing plate 30. The mounting seat 41 is fixedly connected with a stabilizing block 43 extending into the inside of the fixing plate 30. A slider 44 is slidably provided inside the mounting seat 41. The slider 44 and the connecting block 45 of the stabilizing plate 50 are fixedly connected. A stabilizing spring 46 is provided inside the mounting seat 41 to resist the slider 44. After installation, the restoring force of the stabilizing spring 46 can give a force to the slider 44, thereby acting on the connecting block 45 and the stabilizing plate 50 in turn, so that the stabilizing plate 50 is always close to the fixing frame 11 (the stabilizing plates 50 on both sides will interact with each other), thereby generating a large amount of friction to prevent the stabilizing plate 50 from falling off, thereby maintaining the stability of the screen module 20 after installation;

[0042] During installation, the screen module 20 is pushed between the rods of the fixing frame 11. Under the action of the inclined surface, the thrust will generate a component force to offset the force given by the stabilizing spring 46, so that the stabilizing plate 50, the connecting block 45 and the slider 44 can slide until the stabilizing plate 50 enters the interior of the fixing frame 11. The installation of the screen module 20 is completed. Otherwise, it can be disassembled. The operation is simple and convenient for disassembly and assembly.

[0043] To facilitate the disassembly of the screen module 20 after overall installation, please refer to Figure 1 , 4 5. A disassembly structure 60 is provided on the front of the outer frame 10 for assisting the disassembly of the screen module 20. Specifically, the disassembly structure 60 includes a movable block 61 slidably arranged inside the outer frame 10. Both sides of the movable block 61 are fixed with fixed blocks 62. The fixed block 62 is close to the outer side of the outer frame 10. The fixed block 62 is fixedly connected to the outer frame 10 by screws 63. Both sides of the fixed block 62 are fixed with guide rods 64 slidably arranged inside the outer frame 10. When necessary, the screws 63 are unscrewed, and then the movable block 61 can be slid outward to slide it out, thereby exposing the movable block 61. The screen module 20 on the side of the movable block 61 and the side of the fixed plate 30, and then the user can lift the corresponding screen module 20 through the side of the fixed plate 30, such as by manually digging into the gap between the fixed plate 30 and the fixed frame 11 (because there is a mounting seat 41 between the fixed plate 30 and the fixed frame 11, so there is a gap at the position where the mounting seat 41 is not set) and pulling, the above-mentioned friction force can be offset to pull out the corresponding screen module 20 for disassembly, and then the screen modules at other positions will no longer have gaps, and the user can disassemble them one by one. The operation is simple and convenient to disassemble.
