Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0024] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0025] Example

[0026] Reference Figures 1-4 This is an embodiment of the present invention, which provides an LED display screen anti-collision protection device, including,

[0027] The protective mechanism 100 includes a mounting frame 110 and a protective glass 120 fixedly connected to the inner surface of the mounting frame 110 and used to protect the screen of the display body S.

[0028] It should be noted that the mounting frame 110 is used to provide a mounting base for the protective glass 120 and is connected to the disassembly and assembly mechanism 200, so that the protective glass 120 can be fixed on the display screen body S. The protective glass 120 is used to directly protect the screen of the display screen body S. When an object collides, it can absorb and disperse the impact force, reduce the damage to the screen, and reduce the risk of screen breakage and damage. It covers the front of the display screen and forms a direct protective barrier.

[0029] The disassembly and assembly mechanism 200 includes a load-bearing component 210 for providing basic connection support for the mounting frame 110 and the display body S, which is fixedly mounted on the outer surface of the mounting frame 110.

[0030] And a clamping assembly 220 for quickly mounting the mounting frame 110 and the support assembly 210 onto the surface of the display body S, which is located inside the support assembly 210.

[0031] Specifically, the load-bearing component 210 includes an L-shaped rod 211 fixedly installed on the outer surface of the mounting frame 110, and a fixing box 212 fixedly connected to the outer end face of the L-shaped rod 211.

[0032] It should be noted that the L-shaped rod 211 is used to connect the mounting frame 110 and the fixing box 212, and provides support for the entire disassembly and assembly mechanism 200 through the fixing box 212.

[0033] Furthermore, the clamping assembly 220 includes a pressure block 221 movably connected to the inner surface of the fixing box 212, a force groove 222 formed on the surface of the pressure block 221, a swing block 223 movably connected to the inner wall of the force groove 222, a clamping block 224 movably connected to the inner surface of the fixing box 212 away from the pressure block 221 and clamping the pressure block 221 onto the surface of the display body S, a force groove 225 formed on the surface of the clamping block 224 and used in conjunction with the swing block 223, a limiting post 226 fixedly connected to the outer end face of the pressure block 221, a limiting groove 227 formed on the surface of the fixing box 212 and used in conjunction with the limiting post 226 to limit the pressure block 221, and a first spring 228 and a second spring 229 respectively fixedly installed on the outer surfaces of the pressure block 221 and the clamping block 224.

[0034] The pressure block 221 is movable under external force and squeezes the swing block 223 through the force groove 222, causing the swing block 223 to rotate around the support shaft 231, thereby pushing the clamping block 224 to retract, ensuring that the L-shaped rod 211 and the clamping block 224 can be smoothly fitted onto the outside of the display screen body S. The pressure block 221 is limited by the cooperation of the limiting post 226 and the limiting groove 227. The first spring 228 is fixedly installed on the outer surface of the pressure block 221, and the second spring 229 is fixedly installed on the outer surface of the clamping block 224. When the pressure on the pressure block 221 is released, the reaction force of the first spring 228 and the second spring 229 simultaneously provides the pressure block 221 and the clamping block 224 with a reset elastic force and a buffer force, causing the clamping block 224 to move closer to the L-shaped rod 211, thereby clamping the surface of the display screen body S with the fixing box 212.

[0035] Preferably, the outer end face of the swing block 223 slides in contact with the inner wall of the force groove 225, the outer end face of the limiting post 226 slides in contact with the inner wall of the limiting groove 227, the outer surface of the first spring 228 abuts against the outer surface of the pressure block 221, and the inner wall of the second spring 229 abuts against the inner wall of the fixing box 212.

[0036] It should be noted that the disassembly and assembly mechanism 200 also includes a locking component 230 for supporting the swing block 223 and preventing accidental rotation of the swing block 223 from causing displacement of the clamping block 224, which is located inside the fixing box 212.

[0037] Furthermore, the locking assembly 230 includes a support shaft 231 fixedly connected to the inner surface of the swing block 223, a ratchet 232 fixedly sleeved on the through end of the support shaft 231, a rotating post 233 fixedly connected to the outer surface of the fixing box 212, a pawl 234 rotatably sleeved on the outer surface of the rotating post 233 and used in conjunction with the ratchet 232, and a torsion spring 235 sleeved on the outer side of the rotating post 233 and used in conjunction with the pawl 234.

[0038] It should be further explained that the support shaft 231 provides rotational support for the swing block 223, ensuring that the swing block 223 can swing stably. Through the cooperation of the ratchet 232, pawl 234 and torsion spring 235, the rotational direction of the support shaft 231 can be limited, preventing the swing block 223 from rotating accidentally and causing the clamping block 224 to shift. The rotating column 233 provides rotational support for the pawl 234, allowing the pawl 234 to rotate around it. When the swing block 223 presses down... Figure 2 When the pawl 234 rotates clockwise in the direction shown, the pawl 234 engages with the ratchet 232 under the action of the torsion spring 235, preventing the ratchet 232 from reversing, thereby locking the position of the swing block 223.

[0039] Specifically, the support shaft 231 is fixedly installed on the inner wall of the pressure block 221 via a bearing, and the torsion spring 235 is fixedly installed on the outer surface of the fixing box 212, with its other end fixedly connected to the outer surface of the pawl 234.

[0040] In use, the protective mechanism 100 is aligned with the display screen body S, and the end of the pawl 235 is pressed to rotate it around the rotation 235 until it is disengaged from the ratchet 232. External force is applied to the pressure block 221, which is driven to move along the inner surface of the fixing box 212. The pressure block 223 is squeezed by the force groove 222 on its surface, causing the swing block 223 to rotate around the support shaft 231. The swing block 223 then applies pressure to the force groove 225 on the surface of the clamping block 224, thereby pushing the clamping block 224 to retract and widening the gap between the L-shaped rod 211 and the clamping block 224, ensuring that it can be smoothly fitted onto the outside of the display screen body S. At the same time, the limiting post 226 slides in the limiting groove 227 to limit the pressure block 221.

[0041] The pressure on the pressure block 221 is released, and the first spring 228 and the second spring 229 provide a reset spring force and a buffer force to the pressure block 221 and the clamping block 224 respectively, causing the clamping block 224 to move towards the L-shaped rod 211, firmly clamping the fixing box 212 onto the surface of the display body S, and the protective glass 120 covers the front of the display screen. The swing block 223 is pressed down. Figure 2 When the clockwise rotation is shown, it drives the support shaft 231 to rotate synchronously. Then, the support shaft 231 drives the ratchet 232 to rotate with the swing block 223. The pawl 234 engages with the ratchet 232 under the action of the torsion spring 235 to prevent the ratchet 232 from reversing, lock the position of the swing block 223, and prevent the clamping block 224 from being displaced.

[0042] In summary, by cooperating with the protective mechanism 100 and the disassembly and assembly mechanism 200, external force is applied to the pawl 235 and the pressure block 221 in sequence, and then the L-shaped rod 211 and the clamping block 214 are fitted onto the outside of the display screen body S. After the external force is removed, the protective glass 120 can be quickly fixed to the outside of the display screen body S. Compared with the traditional bolt connection method, the operation is simple and there are fewer steps, so as to significantly shorten the installation time and avoid the effect of complex installation affecting the project progress in large-scale installation scenarios.
