[0027] like Figures 1-4 As shown, this embodiment provides an adjustable light barrier for an outdoor display screen, comprising a bracket 1, an adjustment knob 2, a first light barrier 3 and a second light barrier 4, wherein the bracket 1 is provided with an adjustment hole;

[0028] The adjusting knob 2 is rotatably mounted on the adjusting hole, and the adjusting knob 2 is provided with an adjusting column 2a; the first light baffle 3 is mounted on the bracket 1, and the first light baffle 3 is provided with a first light-transmitting slit; the second light baffle 4 is slidably arranged between the bracket 1 and the first light baffle 3, and the second light baffle 4 is provided with an adjusting slot 4a close to the side wall of the bracket 1, the adjusting housing is inserted into the adjusting slot 4a, and the second light baffle 4 is provided with a second light-transmitting slit 4b; wherein, when the adjusting knob 2 is rotated, the adjusting column 2a slides in the adjusting slot 4a, thereby driving the second light baffle 4 to slide relative to the first light baffle 3, so that the first light-transmitting slit and the second light-transmitting slit 4b are misaligned, thereby adjusting the degree of light blocking.

[0029] In some preferred embodiments of the present invention, the first light baffle 3 is provided with a rib that is used to restrict the movement of the second light baffle 4 in a certain direction, thereby enabling the second light baffle 4 to move in a single direction. In this way, the rib can restrict the second light baffle 4, ensuring that the second light baffle 4 moves in only one direction, further ensuring that the first light-transmitting slit and the second light-transmitting slit 4b can be misaligned when the second light baffle 4 moves.

[0030] In some preferred embodiments of the present invention, the adjusting knob 2 is cylindrical, and the adjusting post 2a is not located on the central axis of the adjusting knob 2. Therefore, when the adjusting knob 2 is rotated, the adjusting post 2a changes height because it is not located on the central axis of the adjusting knob 2, thereby adjusting the height of the second light baffle 4 via the adjusting slot 4a.

[0031] In some preferred embodiments of the present invention, the adjusting groove 4a is V-shaped. Thus, the V-shaped adjusting groove 4a can ensure that the adjusting knob 2 has a larger rotation angle, making adjustment easier.

[0032] In some preferred embodiments of the present invention, the bracket 1 is provided with a plurality of positioning posts, and the first light baffle 3 is provided with positioning grooves corresponding to the positioning posts, and the positioning posts are inserted into the positioning grooves.

[0033] In some preferred embodiments of the present invention, the second light barrier 4 is provided with a guide rail, and the first light barrier 3 is provided with a guide groove, wherein the guide rail is slidably inserted into the guide groove. In this way, the guide rail and the guide groove cooperate to further ensure the adjustment stability of the second light barrier 4.

[0034] In some preferred embodiments of the present invention, the adjusting knob is provided with a glass bead 2b for limiting the position.

[0035] Compared with the prior art, the adjustable light baffle of the outdoor display screen of the present application is provided with a first light baffle 3 and a second light baffle 4. By providing a first light-transmitting slit on the first light baffle 3 and a second light-transmitting slit 4b on the second light baffle 4, when the first light-transmitting slit and the second light-transmitting slit 4b are misaligned, the first light baffle 3 and the second light baffle 4 can cooperate to block light, and an adjustment knob 2 is provided. When the adjustment column 2a on the adjustment knob 2 slides in the adjustment groove 4a of the second baffle, the second light baffle 4 can be driven to move, thereby achieving the misalignment of the first light-transmitting slit and the second light-transmitting slit 4b, thereby achieving light blocking adjustment as needed.
