[0027] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0028] Embodiment 1:

[0029] In one embodiment, Figure 1-Figure 5 As shown, a freely movable opening and closing device for an LED screen is provided, wherein an LED display screen 2 is arranged on one side surface of a mounting plate 1, connecting components are arranged at the upper and lower ends of the mounting plate 1, and blocking components are arranged at the left and right ends of the mounting plate 1. The blocking components include blocking blocks 5 fixedly connected to the left and right ends of the mounting plate 1 to prevent dust from entering the interior of the overall opening and closing device from the two ends to cause damage to the LED display screen 2, a moving component 6 is arranged inside the connecting component, and an opening and closing component is arranged at the other end of the moving component 6.

[0030] In one embodiment, Figure 3 and Figure 5 As shown, the connection component includes a connection block 3 fixedly connected to the upper and lower ends of the mounting plate 1. The connection block 3 controls the movement of the moving component 6 while protecting the LED display screen 2 installed on the mounting plate 1, and prevents dust from entering the interior from the upper end of the mounting plate 1 and affecting the LED display screen 2. A limiting component is arranged inside the connection block 3, and blocking components are arranged at both ends of the connection block 3. The limiting component includes a slide groove 4 opened on the surface of the connection block 3, and the slide groove 4 is T-shaped. The moving component 6 slides inside the slide groove 4. The T-shape can limit the moving component 6 in the slide groove 4, thereby ensuring the stability of the movement of the pulley 61.

[0031] In one embodiment, Figure 4 and Figure 5As shown, the moving assembly 6 includes a plurality of pulleys 61 arranged inside the slide groove 4, a rotating shaft 62 is arranged between the pulleys 61, and the opening and closing assembly is fixedly connected to the surface of the rotating shaft 62. The moving assembly 6 includes a plurality of pulleys 61 arranged inside the slide groove 4, a rotating shaft 62 is arranged between the pulleys 61, and the opening and closing assembly is fixedly connected to the surface of the rotating shaft 62. The opening and closing assembly includes a connecting rod 7 fixedly connected to the surface of the rotating shaft 62, and an opening and closing plate 8 is rotatably connected to the surface of the connecting rod 7. The opening and closing plate 8 is made of aluminum alloy. The opening and closing plate 8 made of aluminum alloy includes a fixing column 9 fixedly connected between the connecting blocks 3, and one end of the opening and closing plate 8 is rotatably connected to the surface of the fixing column 9. When the LED display screen 2 needs to be used, the user can slide in the slide groove 4 by controlling the pulley 61, thereby driving the opening and closing plate 8 to fold and expose the LED display screen 2 installed on the mounting plate 1. After use, the user can slide in the opposite direction in the slide groove 4 by controlling the pulley 61 until the opening and closing plate 8 is unfolded to achieve the purpose of sealing the internal LED display screen 2 and protect the LED display screen 2.

A control component is provided at the center of the surface of the closing block 10, and the control component includes a pulling block 11 fixedly connected to the surface of the closing block 10. A pulling groove 12 is provided on the surface of the pulling block 11. The user can pull the pulling groove 12 to pull the pulling block 11. At this time, the pulling block 11 drives the closing block 10 to move, thereby controlling the unfolding and folding of the opening and closing plate 8, and achieving the purpose of freely moving and opening and closing the LED screen.

[0034] The above-mentioned embodiment discloses a free-moving opening and closing device for an LED screen, wherein, when the LED display screen 2 needs to be used, the user can control the pulley 61 to slide in the slide groove 4, thereby driving the opening and closing plate 8 to fold, and the LED display screen 2 installed on the mounting plate 1 is exposed. After use, the user can control the pulley 61 to slide in the slide groove 4 in the opposite direction until the opening and closing plate 8 is unfolded to achieve the purpose of closing the internal LED display screen 2, thereby protecting the LED display screen 2. The user can pull the pulling block 11 by pulling the pulling groove 12. At this time, the pulling block 11 drives the closing block 10 to move, thereby controlling the unfolding and folding of the opening and closing plate 8, and achieving the purpose of freely moving and opening and closing the LED screen.
