[0032] By setting a driving gear member 23 to drive the driven gear member 32 to rotate, the right blade assembly 2 is driven to rotate to adjust the angle between the left blade assembly 1 and the right blade assembly 4, thereby adjusting the angle of adjacent LED curved screens. The angle of adjacent LED curved screens can be adjusted without replacing the connecting device, which facilitates the use of the LED curved screen and does not require customized connecting devices of different angles and sizes, thereby reducing costs.

[0033] The left blade assembly 1 includes a left blade member 11 and a first connecting member 12. The first connecting member 12 is connected to the left blade member 11 and is sleeved on both ends of the carrier 21.

In the present embodiment, the number of the first connecting holes 111 is 6, and the longitudinal section thereof is in the shape of a runway, so that the connecting device can be used for LED display screens of different sizes and different bending angles.

[0034] The right blade assembly 4 includes a right blade member 41 and a second connecting member 42. The second connecting member 42 is connected to the right blade member 41 on one side and to the driven shaft member 32 on the other side. The second connecting member 42 is sleeved on the bearing member 21 and connected to the inner side of the first connecting member 12. A plurality of second connecting holes 411 are provided on the right blade member 41, so that in actual use, different second connecting holes 411 can be selected according to the setting positions of the mounting holes behind different LED display screens, so that the connecting device can be used for different LED display screens, and there is no need to customize the connecting devices of different second connecting holes 411 according to the positions of the mounting holes behind the LED display screen, thereby reducing the cost. In the present embodiment, the number of the second connecting holes 411 is 6, and the longitudinal section thereof is in the shape of a runway, so that the connecting device can be used for LED display screens of different sizes and different bending angles.

[0035] The first connecting member 12 is provided with a pointing portion 121, and the second connecting member 42 is provided with a scale portion 421, and the pointing portion 121 is adjacent to the scale portion 421. By providing the pointing portion 121 and the scale portion 421, the angle between the left blade assembly 1 and the right blade assembly 4 can be directly observed, so that the angle can be directly adjusted to the required angle during use. In this embodiment, the angle between the left blade assembly 1 and the right blade assembly 4 can be adjusted between -25° and 25°.

[0036] Reference Figure 1-Figure 4 , Figure 4 Schematic diagram of the structure of the left blade assembly and the bearing member in the embodiment. The left blade assembly 1 also includes a connecting plate 13, which is arranged at one end of the first connecting member 12 and fixedly connected to the first connecting member 12 by screws. A first octagonal receiving groove 131 is provided on the side of the connecting plate 13 facing the first connecting member 12, and a second octagonal receiving groove 122 is provided on the side of the first connecting member 12 opposite to the connecting plate 13. Both ends of the bearing member 21 are octagonal structures, and the octagonal structures at both ends of the bearing member 21 extend into the first octagonal receiving groove 131 and the first octagonal receiving groove 131 respectively, so that when the left blade assembly 1 and the right blade assembly 4 are in a fixed state, the connecting device is not easy to rotate even if it is subjected to external force.

[0037] Reference Figure 1-Figure 7 , Figure 5 is a schematic diagram of the structure of the active drive component and the driven drive component in the embodiment, Figure 6 is a cross-sectional view of the active drive assembly in the embodiment, Figure 7Schematic diagram of a part of the structure of the active drive assembly in the embodiment. The rotating member 22 includes a rotating portion 221 and a rotating shaft 222, the rotating portion 221 is connected to the rotating shaft 222, and the active gear member 23 is sleeved on the rotating shaft 222. The rotating portion 221 is rotated by a tool, the rotating portion 221 rotates to drive the rotating shaft 222 to rotate, the rotating shaft 222 rotates to drive the active gear member 23 to rotate, the active gear member 23 rotates to drive the driven gear member 32 to rotate, thereby driving the right blade assembly 2 to rotate, so as to adjust the angle between the left blade assembly 1 and the right blade assembly 4.

[0038] The active drive assembly 2 further includes a stopper 24, which is sleeved on the rotating member 22. The stopper 24 includes a limiting portion 241, a reset elastic portion 242 and a stopper 243. The rotating member 221, the limiting portion 241, the reset elastic portion 242 and the stopper 243 are sequentially arranged from top to bottom, and the limiting end of the limiting portion 241 extends into the stopper 243. The stopper 243 is connected to the bearing member 21, and its stopping end abuts against the rotating shaft 222. By providing the reset elastic portion 242, when the limiting portion 241 is not squeezed by an external force, the limiting end of the limiting portion 241 is always located in the stopper 243.

[0039] The limiting portion 241 includes a pressing block 2411 and a limiting block 2412. One surface of the pressing block 2411 abuts against the rotating portion 221, and the other surface is connected to one end of the limiting block 2412. A limiting groove 2431 is provided on the stopper 243, and the other end of the limiting block 2412 extends into the limiting groove 2431. In this embodiment, the pressing block 2411 is a circular ring, and the number of the limiting blocks 2412 is two, and the two limiting blocks 2412 are relatively arranged on the same side of the pressing block 2411. The limiting block 2412 cooperates with the limiting groove 2431 to limit the rotation of the rotating shaft 222, so that the connecting device is fixed at a predetermined angle.

[0040] The stopper 243 further comprises a stopper bearing seat 2432, a stopper block 2433 and a stopper spring 2434. The stopper bearing seat 2432 is sleeved on the rotating shaft 222, the stopper block 2433 is movably arranged on the stopper bearing seat 2432, one end of the stopper spring 2434 abuts against the stopper block 2433, and the other end abuts against the bearing member 21, and the limiting groove 2431 penetrates the stopper bearing seat 2432 and the stopper block 2433. The rotating shaft 222 is provided with a tooth pattern 2221, and the stopper end of the stopper block 2433 abuts against the tooth pattern 2221. The limiting groove 2431 always limits the limiting part 241 to make a rotational motion, so as to prevent the limiting part 241 from rotating with the rotating part 221. A protrusion 2413 is arranged at one end of the limiting block 2412 extending into the limiting groove 2431, and the rotation of the stopper block 2433 is limited by providing the protrusion 2413. By providing the tooth pattern 2221 and the protrusion 2413, the stop end of the stop block 2433 is abutted against the tooth pattern 2221, thereby limiting the rotation of the rotating shaft 222. When the stop block 2433 is rotated by the tooth pattern 2221, the stop block 2433 compresses the stop spring 2434 along the rotation direction. When the stop block 2433 rotates to a preset angle, the rotating shaft 222 stops rotating, and the stop block 2433 is reset under the action of the elastic force of the stop spring 2434. In this embodiment, there are two stop blocks 2433, and the two stop blocks 2433 are relatively arranged on both sides of the stop bearing seat 2432. Two stop springs 2434 are arranged on each stop block 2433, and the two stop springs 2434 are arranged at both ends of the side of the stop block 2433 facing the bearing member 21, so that no matter whether the stop block 2433 rotates clockwise or counterclockwise, a spring on each stop block 2433 is compressed.

[0041] The rotating part 221 also includes a rotating head 2211 and a bearing 2212. The bearing 2212 is disposed between the rotating head 2211 and the pressing block 2411. One end of the rotating part 221 is exposed to the carrier 21, and the other end is movably connected to the rotating shaft 222. In this embodiment, the end of the rotating part 221 exposed to the carrier 21 is a hexagonal rotating head. By providing the hexagonal rotating head, the connection device is easy to maintain and assemble. By providing the bearing 2212, when the rotating head 2211 rotates, it will not drive the pressing block 2411 to rotate, thereby preventing the pressing block 2411 from rotating and affecting the stopper 24.

[0042] When rotating the connecting device, the rotating head 2211 is pressed downward by an external tool, such as a hexagonal wrench, so as to push the limiting portion 241 and the resetting elastic portion 242 downward, so that the protrusion 2413 is no longer located in the limiting groove 2431. At this time, the protrusion 2413 no longer limits the rotation of the stop block 2433, and then the hexagonal wrench is rotated to drive the rotating head 2211 and the rotating shaft 222 to rotate. The rotation of the rotating shaft 222 drives the driving gear member 23 to rotate, and the driven gear member 32 to rotate, thereby driving the right blade assembly 2 to rotate, so as to adjust the angle between the left blade assembly 1 and the right blade assembly 4. During the rotation of the rotating shaft 222, the stop block 2433 is driven to rotate by the tooth pattern 2221. When the stop block 2433 rotates, the stop spring 2434 is compressed along the rotation direction. When it rotates to a preset angle, the rotating shaft 222 stops rotating, and the stop block 2433 is reset under the action of the elastic force of the stop spring 2434. The hexagonal wrench is released, and the limiting portion 241 returns to its original position under the rebound action of the reset elastic portion 242. At this time, the protrusion 2413 is reset, and the protrusion 2413 limits the rotation of the stop portion 243, thereby limiting the rotation of the rotating shaft 222 and fixing the connecting device at a required angle. By setting a driving gear member 23 to drive the driven gear member 32 to rotate, the right blade assembly 2 is driven to rotate to adjust the angle between the left blade assembly 1 and the right blade assembly 4. At the same time, through the cooperation of the stop block 2433 and the tooth pattern 2221, the connecting device can stop being fixed at any angle, so as to adjust the angle of adjacent LED curved screens. The angle of adjacent LED curved screens can be adjusted without replacing the connecting device, which facilitates the use of the LED curved screen and does not require customized connecting devices of different angles and sizes, thereby reducing costs.

[0043] The driven shaft member 32 includes a driven shaft 321 and a fixed shaft 322. The driven gear member 31 is sleeved on the driven shaft 321. One end of the driven shaft 321 is connected to the second connecting member 42, and the other end is respectively in contact with the second connecting member 42 and the fixed shaft 322. The fixed shaft 322 is provided on the right blade assembly 4. One end of the driven shaft member 32 is fixed to the second connecting member 42 through the fixed shaft 322, so that one end of the driven shaft 321 can be fixed first during installation, and the other end can be fixed by the fixed shaft 322 after being installed to a predetermined position, which is convenient for the installation of the driven shaft 321.

[0044] In summary: the angle-adjustable connecting device in the present application drives the driven gear member to rotate by setting an active gear member, thereby driving the right blade assembly to rotate, so as to adjust the angle between the left blade assembly and the right blade assembly. At the same time, through the cooperation of the stop block and the tooth pattern, the connecting device can stop being fixed at any angle, thereby adjusting the angle of adjacent LED curved screens. The angle of adjacent LED curved screens can be adjusted without replacing the connecting device, which facilitates the use of the LED curved screen and does not require customized connecting devices of different angles and sizes, thereby reducing costs.

[0045] The above is only an embodiment of the present invention and is not intended to limit the present invention.
