[0023] Example

[0024] The display screen is usually fixed to the hanging device by bolts, which makes it very inconvenient to install. Secondly, the tilt angle and circumferential angle after installation are not easy to adjust synchronously, and need to be adjusted separately, which makes the adjustment very inconvenient;

[0025] To do this, see Figure 1-3 The utility model provides a hanging device for an LED display screen, comprising: a mounting base 1 and a display screen body 7, a rotating rod 2 is rotatably connected to the middle of the bottom end of the mounting base 1, and an adjusting plate 4 is rotatably connected to the bottom end of the rotating rod 2 through a rotating shaft 3;

[0026] It also includes a fixed installation structure 5 and a synchronous adjustment structure 6. The fixed installation structure 5 is installed on the adjustment plate 4 and connected to the back of the display screen body 7. The fixed installation structure 5 can facilitate the fast installation and fixing of the display screen body 7 on the adjustment plate 4. The end surface of the adjustment plate 4 is a U-shaped structure.

[0027] The synchronous adjustment structure 6 is installed on the back of the adjustment plate 4 and connected to the rotating rod 2. The synchronous adjustment structure 6 can adjust the inclination angle of the adjustment plate 4 on the one hand, and the circumferential angle of the adjustment plate 4 on the other hand.

[0028] Further as Figure 1-3 As shown, it is worth explaining in detail that, in order to facilitate the installation of the display screen body 7 on the adjustment plate 4, a fixed installation structure 5 is provided, including two symmetrically arranged I-shaped inserting strips 51 fixedly connected to the back of the display screen body 7, and the adjustment plate 4 is provided with insertion channels matching the I-shaped inserting strips 51, and the backs of the two adjustment plates 4 are fixedly connected to two symmetrically arranged connecting blocks 52, and the two connecting blocks 52 are threadedly connected with hand screws 53, and one end of the hand screws 53 after being locked is pressed against the outer side of the I-shaped inserting strip 51.

[0029] Further as Figure 1-3 As shown, it is worth specifically explaining that, in order to be able to adjust the circumferential angle of the adjustment plate 4 at the same time when adjusting the inclination angle of the adjustment plate 4, so as to meet the use of the display screen body 7 at different inclination angles and circumferential angles, a synchronous adjustment structure 6 is provided, including a push-pull rod 61 hinged on the back of the adjustment plate 4, the top end of the push-pull rod 61 is hinged to the outside of the sliding seat 62, the cross-section of the sliding seat 62 is an I-shaped structure, the sliding seat 62 is slidably connected to the sliding groove provided on the rotating rod 2, and a screw 63 is threadedly connected to the sliding seat 62, both ends of the screw 63 are rotatably connected to the sliding groove, and the bottom end of the screw 63 extends to the bottom of the rotating rod 2. The outer side of gear a64 is meshed with gear b65, gear b65 is fixed to the outer side of spline sleeve 66, spline sleeve 66 is rotatably connected to the back of rotating rod 2 through bearing seat, a matching spline shaft 67 is movably installed in the mounting shaft hole of spline sleeve 66, an inverted L-shaped guide rod 68 is movably inserted on the bearing seat, the spline shaft 67 is rotatably connected to the inverted L-shaped guide rod 68, the top of the bearing seat is connected to the inverted L-shaped guide rod 68 through a spring 69, the bottom end of the spline shaft 67 is fixed with a handle 610, and a plurality of card holes 611 arranged in a ring array and matching the top of the spline shaft 67 are provided at the bottom end of the mounting seat 1.

[0030] Among them, the spline sleeve 66 and the spline shaft 67 are arranged so that after the spline shaft 67 moves in the spline sleeve 66, the spline sleeve 66 can still be rotated, thereby prompting the gear b65 to transmit the gear a64, thereby causing the screw 63 to rotate, and the depth of the card hole 611 is smaller than the thickness of the mounting seat 1.

[0031] In summary: when the LED display screen hanging device is used, the two I-shaped inserting strips 51 on the back of the display screen body 7 can be respectively inserted into the insertion channels provided on the adjustment plate 4. In addition, the I-shaped inserting strips 51 can be fixed by respectively tightening the two hand screws 53, thereby facilitating the installation of the display screen body 7 on the hanging device. Secondly, the spline shaft 67 is pulled by the handle 610, so that the top end of the spline shaft 67 is disengaged from the corresponding clamping hole 611. In addition, the inverted L-shaped guide rod 68 moves up and down on the bearing seat and compresses the spring 69. At this time, When the spline shaft 67 is rotated through the handle 610, the spline sleeve 66 is rotated, and the gear b65 is prompted to transmit the gear a64, so that the screw 63 is rotated. Due to the threaded connection between the sliding seat 62 and the screw 63, and the action of the push-pull rod 61, the inclination angle of the adjustment plate 4 can be adjusted. In addition, the top end of the rotating rod 2 is rotatably connected to the bottom of the mounting seat 1, so that the circumferential angle of the rotating rod 2 can also be adjusted, thereby facilitating the adjustment of the circumferential angle of the adjustment plate 4 to meet the use of the display screen body 7 at different inclination angles and circumferential angles.
