[0029] Refer to Figure 1 and Figure 2, an embodiment of the present utility model discloses a safety door for a stadium fence screen, which includes a first display screen 1, a second display screen 2, and a slider mechanism 3 connected between the first display screen 1 and the second display screen 2. The first display screen 1 and the second display screen 2 can be arranged at an angle based on the slider mechanism 3. The angle between the first display screen 1 and the second display screen 2 is less than or equal to 180° and greater than or equal to 90°. The slider mechanism 3 includes an arc-shaped base 31 and an arc-shaped slider 32. An arc-shaped sliding cavity is provided inside the arc-shaped base 31, and the arc-shaped base 31 slides in the arc-shaped sliding cavity along the arc direction of the arc-shaped sliding cavity. The first display screen 1 and the second display screen 2 are respectively connected to the arc-shaped base 31 and the arc-shaped slider 32. That is, when the arc-shaped slider 32 slides out of the arc-shaped sliding cavity to the maximum position, the first display screen 1 and the second display screen 2 are in a folded state, and the angle between the first display screen 1 and the second display screen 2 is equal to 90°. In one case, the second display screen 2 remains stationary, and the first display screen 1 rotates 90° relative to the second display screen 2. An opening is formed between the side of the first display screen 1 away from the second display screen 2 and its adjacent display screen. This opening forms a safety passage for players and staff to evacuate from the stadium. In another case, the first display screen 1 and the second display screen 2 rotate simultaneously. An opening is formed between the side of the first display screen 1 away from the second display screen 2 and its adjacent display screen, and an opening is also formed between the side of the second display screen 2 away from the first display screen 1 and its adjacent display screen. Players and staff can evacuate from the stadium through the two openings.
[0030] In a specific embodiment, referring to Figures 3 - 5 , Figure 8 , the arc-shaped base 31 includes a lower base 311 and an upper base 312. An outer retaining ring 313 and an inner retaining ring 314 are provided on the lower base 311. The upper base 312 is connected and installed to the outer retaining ring 313 and the inner retaining ring 314 by screws 315. The opposite sides of the outer retaining ring 313, the inner retaining ring 314, the lower base 311, and the upper base 312 form the arc-shaped sliding cavity. When the arc-shaped slider 32 slides in the arc-shaped sliding cavity, the surface of the arc-shaped slider 32 slides in contact with the side walls of the outer retaining ring 313, the inner retaining ring 314, the lower base 311, and the upper base 312 respectively.
[0031] Furthermore, referring to Figures 3 - 6 , Figure 8, on both sides of the arc-shaped slider 32, a first arc-shaped chute 321 and a second arc-shaped chute 324 are respectively provided. On the lower base 311 and the upper base 312, a first sliding part 318 and a second sliding part 319 are respectively provided. The first sliding part 318 and the second sliding part 319 are respectively slidably connected to the first arc-shaped chute 321 and the second arc-shaped chute 324. In this way, when the arc-shaped slider 32 slides in the arc-shaped sliding cavity, the first sliding part 318 slides in the first arc-shaped chute 321, and at the same time, the second sliding part 319 slides in the second arc-shaped chute 324, which can achieve secondary limiting of the sliding of the arc-shaped slider 32 and make its sliding in the arc-shaped sliding cavity more stable and reliable.
[0032] Furthermore, referring to Figure 6 , the first arc-shaped chute 321 and the second arc-shaped chute 324 are respectively close to both ends of the arc-shaped slider 32, which can increase the maximum distance that the arc-shaped slider 32 slides out of the arc-shaped base 31. In addition, the first arc-shaped chute 321 and the second arc-shaped chute 324 are arranged in a staggered manner in the vertical direction, which is convenient for the processing of the first arc-shaped chute 321 and the second arc-shaped chute 324 on the arc-shaped slider 32, and avoids the situation that the thickness of the arc-shaped slider 32 at this position is too thin in the same vertical direction, thus affecting the structural stability.
[0033] In this embodiment, referring to Figure 7 , the first sliding part 318 includes a shaft rod and a first bearing 3183 fixed on the first shaft rod 3182. The first shaft rod 3182 is connected to the lower base 311 through a bolt 3181. The end of the first shaft rod 3182 is slidably connected to the bottom of the first arc-shaped chute 321, and the peripheral wall of the first bearing 3183 is in rolling contact with the two side walls of the first arc-shaped chute 321; the second sliding part 319 has the same structure as the first sliding part 318. Specifically, the second sliding part 319 includes a second shaft rod and a second bearing fixed on the second shaft rod. The second shaft rod is connected to the upper base 312 through a bolt. The end of the second shaft rod is slidably connected to the bottom of the second arc-shaped chute 324, and the peripheral wall of the second bearing is in rolling contact with the two side walls of the second arc-shaped chute 324.
[0034] In the above embodiment, the first sliding part 318 and the second sliding part 319 are respectively in rolling contact with the first arc-shaped chute 321 and the second arc-shaped chute 324 in a bearing manner, reducing the friction between them, thereby improving the smoothness of the sliding of the arc-shaped slider 32 in the arc-shaped sliding cavity.
[0035] In this embodiment, referring toFigures 4 - 6 , a first protruding connecting portion 322 is provided on the concave side of the arc-shaped slider 32, and the second display screen 2 is connected and installed to the first protruding connecting portion 322 through a first connecting block 33; the inner retaining ring 314 is provided on one side of the lower base 311, that is, the side of the inner side of the lower base 311 away from the inner retaining ring 314 is a notch, and this notch forms an avoidance opening on the arc-shaped base 31 for avoiding the first convex connecting portion. When the arc-shaped slider 32 slides in the arc-shaped sliding cavity, the first protruding connecting portion 322 passes through the avoidance opening.
[0036] In addition, a second protruding connecting portion 316 is provided on the inner retaining ring 314, the first display screen 1 is connected and installed to the second protruding connecting portion 316 through a second connecting block 34, and a first limiting surface 323 is provided on the first protruding connecting portion 322, and a second limiting surface 317 is provided on the second protruding connecting portion 316. When the first limiting surface 323 abuts against the second limiting surface 317, the arc-shaped slider 32 slides into the arc-shaped sliding cavity, and at this time, the included angle between the first display screen 1 and the second display screen 2 is equal to 180°, that is, the first display screen 1 and the second display screen 2 are in the same plane; when the first bearing 3183 abuts against the inner side section of the first arc-shaped sliding groove 321, the arc-shaped slider 32 slides to the outside of the arc-shaped sliding cavity, and at this time, the included angle between the first display screen 1 and the second display screen 2 is equal to 90°. In this embodiment, through the cooperation of the first limiting surface 323 and the second limiting surface 317, it is ensured that the first display screen 1 and the second display screen 2 are in the same plane after the arc-shaped slider 32 slides into the arc-shaped sliding cavity, thereby not affecting the display effect of the stadium fence screen; through the cooperation of the first bearing 3183 and the first arc-shaped sliding groove 321, the maximum position where the arc-shaped slider 32 slides out of the arc-shaped sliding cavity (the included angle between the first display screen 1 and the second display screen 2 is equal to 90°) is limited, and it can be avoided that the arc-shaped slider 32 slides out of the arc-shaped sliding cavity excessively, resulting in the failure of the slider mechanism 3.
[0037] In this embodiment, referring to Figure 1 , a plurality of the slider mechanisms 3 are provided between the first display screen 1 and the second display screen 2 from top to bottom. Specifically, a slider mechanism 3 is respectively provided at the top and bottom of the connection between the first display screen 1 and the second display screen 2, so that both the sliding effect of the slider mechanism 3 can be ensured and the stability of the first display screen 1 and the second display screen 2 can be ensured.
