Description

Technical Field

[0001] This utility model relates to the field of display screen technology, and in particular to a magnetically detachable protective frame for LED displays. Background Technology

[0002] With the rapid development of information technology, LED displays, with their advantages of high brightness, high contrast, and long lifespan, are widely used in outdoor advertising, stadiums, transportation hubs, commercial centers, and many other fields. During use, LED displays are typically exposed to the external environment and are susceptible to damage from impacts, dust, rain, and other factors, leading to performance degradation. Therefore, protective frames are needed to extend their lifespan and ensure display quality. Existing LED display protective frames mostly use bolts and clips for connection. Bolted frames require specialized tools for installation and disassembly, making the process cumbersome and time-consuming. This is especially true for large LED displays or those installed at high positions, where disassembly and maintenance become extremely difficult, increasing labor and time costs. While clip-connected frames offer some speed improvement, the clips are prone to wear and loosening after prolonged use, resulting in an unstable frame and ineffective protection. Furthermore, the relatively fixed size and structure of the clips offer poor compatibility with different LED display sizes. Therefore, this invention proposes a magnetically detachable LED display protective frame. Utility Model Content

[0028] Embodiment

[0029] As Figure 1 and Figure 2 shown, a magnetic adsorption type detachable LED display protection outer frame proposed by the present utility model includes: a protective side frame 1 arranged at the outer frame of the display screen. The protective side frame 1 is arranged in a "C" - shaped structure, which can be mutually clamped with the outer frame of the display screen and increase the protection area. An installation groove 2 is opened inside the protective side frame 1. A set of racks 3 are slidably arranged inside the installation groove 2, and the rack surfaces of the racks 3 are placed opposite to each other. Opposite ends of the racks 3 are respectively fixedly provided with connecting plates 4. The connecting plates 4 are slidably connected with the installation groove 2. A slot 11 is opened on one side of the connecting plate 4, and first magnetic blocks 5 are respectively embedded on one side of the connecting plate 4.

[0030] Furthermore, a gear 6 is rotatably arranged inside the installation groove 2. The gear ⑥ is meshed with the rack 3. One end of the gear 6 penetrates through the protective side frame 1 and extends to be connected with a rotating cap 7. By means of the rotating cap 7 cooperating with the gear 6, the racks 3 can be simultaneously moved inside the installation groove 2, thereby adjusting the length of the connecting plate 4 extending out of the installation groove 2 to adapt to display screens of different specifications. A card slot 13 is opened on the outer wall of the rotating cap 7. A groove 8 is opened on one side of the protective side frame 1, and the rotating cap 7 is located inside the groove 8.

[0031] As Figure 2 and Figure 3 As shown, a limiting component 9 for limiting the rotation cap 7 is provided inside the groove 8. The limiting component 9 includes a set of guide rods 91 fixedly disposed inside the groove 8. A limiting block 92 is movably sleeved on the outer wall of the guide rods 91, which can make the limiting block 92 move according to the direction of the guide rods 91. A locking block 93 is fixedly disposed on one end of the limiting block 92. Springs 94 are respectively sleeved on the outer wall of the guide rods 91. One end of the spring 94 is fixedly connected to the inner wall of the groove 8, and the other end of the spring 94 is fixedly connected to the limiting block 92. The spring 94 can provide a thrust to the limiting block 92, thereby making the limiting block 92 stably limit the rotation cap 7.

[0032] like Figure 2 and Figure 4 As shown, a connecting component 10 is provided at the corner of the display screen. The connecting component 10 is used to connect the protective side frame 1 of the outer frame of the display screen. The connecting component 10 includes a first connecting block 101 and a second connecting block 102. A plug 12 is fixedly provided on one side of the first connecting block 101 and the second connecting block 102, and the plug 12 can be inserted into the slot 11 on the connecting plate 4 to stably limit the protective side frame 1. Through holes 103 are respectively opened at both ends of the first connecting block 101 and the second connecting block 102. A bolt 104 for limiting the first connecting block 101 and the second connecting block 102 is provided in the through hole 103. A nut 105 is threaded onto one end of the bolt 104. The bolt 104 and the nut 105 cooperate with the first connecting block 101 and the second connecting block 102. The through hole 103 on the 2 can stably limit the first connecting block 101 and the second connecting block 102. A snap-fit ​​groove 106 is provided on one side of the first connecting block 101 and the second connecting block 102. A second magnetic block 107 is provided inside the snap-fit ​​groove 106, which can magnetically attract with the first magnetic block 5 on the connecting plate 4, thereby stably connecting the protective side frame 1 with the first connecting block 101 and the second connecting block 102. A limiting slot 14 is provided on the opposite side of the first connecting block 101 and the second connecting block 102. A limiting block 15 is snap-fitted inside the limiting slot 14. A protective block 16 is fixedly connected to one end of the limiting block 15. The protective block 16 is made of rubber and has a good cushioning effect, which can protect the corners of the display screen and facilitate the replacement of the protective block 16.

[0033] The working principle of this embodiment is as follows: First, the protective side frames 1 with a "C" - shaped structure are respectively sleeved on the four sides of the LED display screen. Then, the limiting block 92 is pushed to slide on the outer wall of the guide rod 91, and then the rotating cap 7 is rotated, which drives the gear 6 to rotate. The gear 6 meshes with the rack 3, causing the rack 3 to slide in the installation groove 2, and further driving the connecting plate 4 to move, enabling the first magnet 5 on the connecting plate 4 to adsorb to the second magnet 107. At this time, the rotation of the rotating cap 7 is stopped, and the pushed limiting block 92 is released. Through the elastic force of the spring 94, the limiting block 92 is pushed to slide on the outer wall of the guide rod 91, so that the clamping block 93 at one end of the limiting block 92 is engaged with the card slot 13 on the outer wall of the rotating cap 7, thereby limiting the connecting plate 4.

[0034] After that, the insertion blocks 12 on the first connecting block 101 and the second connecting block 102 are aligned and inserted into the insertion slots 11 on one side of the connecting plate 4. During the insertion process, the first magnet 5 and the second magnet 107 also magnetically attract each other, further increasing the stability of the connection.

[0035] When replacing the protective block 16, the bolts 104 and nuts 105 on the first connecting block 101 and the second connecting block 102 are unscrewed, the bolts 104 are removed, and the limiting block 15 is taken out from the limiting card slot 14 to achieve the disassembly and replacement of the protective block 16.

[0036] The above - mentioned specific embodiment is only an optional embodiment of the present utility model. Based on the technical solution of the present utility model and the relevant revelations of the above - mentioned embodiment, those skilled in the art can make various alternative improvements and combinations to the above - mentioned specific embodiment.
