[0033] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0034] This embodiment provides a technical solution:

[0035] See also Figure 1-Figure 6 As shown, the LED display screen mounting bracket with adjustable viewing angle includes a display screen 1, a mounting plate 2 is provided on the front side of the display screen 1, two connecting frames 3 are provided on the front side of the mounting plate 2, and mounting frames 4 are provided on the front sides of the connecting frames 3; mounting grooves 20 are provided at the four corners of the mounting plate 2, and connecting bolts 21 threadedly connected to the display screen 1 are penetrated at the mounting grooves 20; two hanging frames 22 are fixed on the front end surface of the mounting plate 2, two through holes 222 are provided on the top of the hanging frames 22, and a limiting groove 221 is provided on one side of the through holes 222; the overall shape of the connecting frame 3 is triangular, and the hanging frame 22 is hung and matched with the front end cross bar of the connecting frame 3, and the rear end of the connecting frame 3 is installed A connecting head 30 and a through groove 31 are provided at the front side of the top of the connecting frame 3, and a transmission shaft 32 is provided at the through groove 31. The transmission shaft 32 passes through the connecting frame 3 and is rotatably connected to the connecting frame 3. Two thread grooves 321 with opposite thread winding directions are provided on the transmission shaft 32. The thread grooves 321 are threadedly connected to connecting blocks 34. A limiting rod 35 is installed on the top of the connecting block 34. The limiting rod 35 passes through the limiting groove 221, and the limiting head 36 is coaxially fixed at the top of the limiting rod 35; a rotating shaft 41 is rotatably installed between the two mounting frames 4, and the upper and lower ends of the rotating shaft 41 are coaxially fixed with limiting rings 412; the rotating shaft 41 passes through the connecting head 30 and is rotatably connected to the connecting head 30.

[0036] In this embodiment, two fixing rings 411 are coaxially keyed at both upper and lower sides of the rotating shaft 41, and the two fixing rings 411 respectively press against the upper and lower ends of the connector 30. The two fixing rings 411 can effectively limit the connector 30 to prevent relative displacement on the rotating shaft 41, thereby improving the stability and safety of the structure.

[0037] In this embodiment, a fixing plate 40 is installed at the rear end of the mounting frame 4, and fixing holes for inserting bolts are opened at the four corners of the fixing plate 40. The design of the fixing plate 40 and the fixing holes thereon enables the mounting frame 4 to be conveniently fixed on a wall or other mounting surface, thereby improving the convenience and firmness of the installation.

[0038] In this embodiment, the overall shape of the mounting frame 4 is U-shaped, and the mounting frame 4 is tightly welded to the fixing plate 40. The U-shaped mounting frame 4 design makes its structure more stable, and the tight welding with the fixing plate 40 further enhances the stability and durability of the overall structure.

[0039] In this embodiment, the connecting frame 3 and the connecting head 30 are an integrally formed structure, and the surfaces of the connecting frame 3 and the connecting head 30 are coated with anti-rust paint. The integrally formed structure reduces the connection gap between the components and improves the integrity and strength of the structure. The coating of anti-rust paint effectively prevents the corrosion of metal parts and prolongs the service life.

[0040] In this embodiment, the end of the transmission shaft 32 is coaxially keyed to an adjustment head 33, and a plurality of anti-skid grooves are provided on the outer wall of the adjustment head 33. This design enables the user to conveniently rotate and adjust the transmission shaft 32, and the anti-skid grooves increase the friction between the hand and the adjustment head 33, preventing slipping during the adjustment process.

[0041] In this embodiment, the mounting plate 2 and the rack 22 are integrally formed, and the rack 22 is L-shaped as a whole. The integrally formed structure enhances the integrity and strength of the mounting plate and the rack, and the L-shaped rack design facilitates the stable connection between the rack 22 and the crossbar of the connecting frame 3;

[0042] In this embodiment, the aperture of the through hole 222 is larger than the width of the limiting groove 221, and the bottom diameter of the limiting head 36 is larger than the diameter of the limiting rod 35 and smaller than the aperture of the through hole 222. The limiting rod 35 and the limiting head 36 of this design can smoothly pass through the through hole 222, which is conducive to the limiting rod 35 entering the limiting groove 221, thereby ensuring the connection stability between the hanging bracket 22 and the connecting bracket 3.

[0043] It should be added that the size of the connecting block 34 is compatible with the size of the through slot 31 . When the transmission shaft 32 rotates, the connecting block 34 will not rotate or shake due to the rotation of the transmission shaft 32 , thereby ensuring the smoothness of the horizontal movement of the connecting block 34 .

[0044] In addition, the transmission shaft 32 in this embodiment is coaxially keyed with two retaining rings. When the connecting block 34 is pressed against the retaining rings, the limit head 36 and the through hole 222 are located on the same vertical plane. When the display screen 1 is lifted upward, the limit head 36 can be detached from the bracket 22 at the through hole 222.

[0045] During specific use, the user first aligns the hanger 22 with the cross bar of the connecting frame 3 and aligns the limit head 36 with the through hole 222. The limit head 36 passes through the through hole 222 at the same time, and the hanger 22 is hung on the cross bar of the connecting frame 3. Then the user rotates the adjusting head 33, and the adjusting head 33 drives the transmission shaft 32 to rotate. At this time, the connecting blocks 34 on both sides move synchronously relative to each other on both sides, and the connecting blocks 34 simultaneously drive the limit rod 35 and the limit head 36 to move horizontally. When the limit rod 35 passes through the limit groove 221 and presses against the end of the limit groove 221, the user stops rotating the adjusting head 33, and the hanger 22 is stably connected to the connecting frame 3, and the display screen 1 is installed.

[0046] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection of the utility model is defined by the attached claims and their equivalents.
