Detailed implementation mode

[0024] In order to make the purpose, technical solution and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0025] In one embodiment, as Figures 1-6 shown, a COB lamp post display screen with adjustable display angle is shown, including a lamp post 100, and an illuminating lamp 101 is arranged at the top of the lamp post 100.

[0026] In this embodiment, a first hoop 201 is coaxially arranged on the upper part of the lamp post 100, a second hoop 202 is coaxially arranged in the middle of the lamp post 100, two first rotating shafts 204 are rotatably arranged between the first hoop 201 and the second hoop 202, the upper end of the first rotating shaft 204 penetrates through the first hoop 201, the top end of the first rotating shaft 204 is coaxially connected with a limiting gear 301, a limiting mechanism is arranged at the position of the first hoop 201 corresponding to the penetration of the first rotating shaft 204, the middle part of the first rotating shaft 204 penetrates through and is connected with a display mounting bracket 401, the display mounting bracket 401 connected by the first rotating shaft 204 on the right side is connected with a COB packaged LED display screen 404 through a second rotating shaft 402 and a third rotating shaft 403, the second rotating shaft 402 is rotatably connected to the middle part on the left side of the display mounting bracket 401, the third rotating shaft 403 is rotatably connected to the lower part on the right side of the display mounting bracket 401, a locking bolt 405 is threadedly connected to the display mounting bracket 401 at a position directly below the third rotating shaft 403, the upper end of the locking bolt 405 contacts the third rotating shaft 403, and by manually operating the limiting mechanism, the first rotating shaft 204 can be rotated to adjust the orientation of the COB packaged LED display screen 404 in the horizontal direction, then the locking bolt 405 is loosened, the orientation of the COB packaged LED display screen 404 is adjusted in the vertical direction, and then the locking bolt 405 is tightened to fix the orientation of the COB packaged LED display screen 404.

[0027] In one embodiment, as Figure 3 shown, the limiting mechanism includes a limiting pin 302 that is slidably connected through the first hoop 201, the upper end of the limiting pin 302 is connected with a limiting block 303, and the limiting block 303 is matched with the gap between the teeth of the limiting gear 301.

[0028] In one embodiment, as Figure 3 shown, the bottom end of the limit pin 302 is threadedly connected to a limit bolt 304, and a return spring 305 is provided between the limit bolt 304 and the lower surface of the first hoop 201.

[0029] In one embodiment, as Figure 3 shown, the limit pin 302 is a square strip.

[0030] In one embodiment, as Figure 2 shown, a shield 406 is provided at the top of the display screen mounting bracket 401.

[0031] In one embodiment, as Figure 2 shown, the screen display area of the COB packaged LED display screen 404 is covered with an ultraviolet filter to reduce the aging speed of the display screen in the sun.

[0034] The above embodiments disclose a COB lamp post display screen with an adjustable display angle. Manually pull up the limit pin 302 to disengage the limit block 303 from the limit gear 301. At this time, the first rotating shaft 204 rotates freely, and the display screen mounting bracket 401 connected to the first rotating shaft 204 rotates accordingly, so as to adjust the orientation of the COB packaged LED display screen 404 in the horizontal direction. Then release the limit pin 302. Under the influence of the self-weight of the limit pin 302 and the elastic force of the return spring 305, the limit block 303 re-enters the gap of the limit gear 301 to limit the rotation of the first rotating shaft 204. Then loosen the locking bolt 405. The locking bolt 405 no longer restricts the rotation between the third rotating shaft 403 and the display screen mounting bracket 401, so that the orientation of the COB packaged LED display screen 404 can be adjusted in the vertical direction. After the adjustment is completed, tighten the locking bolt 405 to fix the orientation of the COB packaged LED display screen 404.
