[0046] See also Figure 3 、 Figure 4 and Figure 6, one end of the second element 10 is rotatably connected to the first longitudinal beam 1 of the first bracket 7. Specifically, a T-shaped member 13 is provided at one end of the second element 10. The T-shaped member 13 has a first boss 1301 and a second boss 1302. The first boss 1301 and the second boss 1302 are respectively disposed in the first mounting groove 502 and the second mounting groove 602 to achieve a sliding connection between the second element 10 and the first mounting groove 502 and the second mounting groove 602, thereby achieving a rotatable connection between the second element 10 and the first longitudinal beam 1. In some embodiments, the first longitudinal beam 1 is provided with an axially extending guide protrusion 101, and the second connecting member 6 is provided with a guide groove 603. The guide protrusion 101 cooperates with the guide groove 603 to enable the second connecting member 6 to be slidably connected relative to the first longitudinal beam 1 and the second longitudinal beam 2. When the second element 10 is installed, the second connecting member 6 slides in the direction away from the first connecting member 5, and the first boss 1301 is inserted into the first mounting groove 502. Then the second connecting member 6 slides in the direction close to the first connecting member 5, and the second boss 1302 is inserted into the second mounting groove 602, thereby realizing the rotational connection between the second element 10 and the first longitudinal beam 1.

[0047] See also Figure 5 and Figure 6 The other end of the second element 10 is inserted into the third rod 901, and the second element 10 can slide relative to the third rod 901 to adjust the distance between the first element 9 and the first longitudinal beam 1.

The first locking member 14 is threadedly connected to the first threaded hole. When the first locking member 14 is rotated, one end of the first locking member 14 can pass through the first threaded hole and abut against the second element 10. The friction between the first locking member 14 and the second element 10 increases, and the second element 10 cannot slide relative to the third rod 901, thereby achieving the locking of the second element 10 and the third rod 901. When the first locking member 14 is rotated in the opposite direction, the first locking member 14 separates from the second element 10, and the second element 10 can slide relative to the third rod 901.

[0048] One end of the third element 11 is rotationally connected to the second longitudinal beam 2 of the first bracket 7. The manner in which the third element 11 is rotationally connected to the second longitudinal beam 2 of the first bracket 7 is the same as the manner in which the second element 10 is rotationally connected to the first longitudinal beam 1 of the first bracket 7 described above, and will not be repeated here.

[0049] The other end of the third element 11 is inserted into the sixth rod 904 . The connection method between the third element 11 and the sixth rod 904 is the same as the connection method between the second element 10 and the third rod 901 described above, which will not be repeated here.

[0050] One end of the fourth element 12 is rotationally connected to the first longitudinal beam 1 of the second bracket 8. The manner in which the fourth element 12 is rotationally connected to the first longitudinal beam 1 of the second bracket 8 is the same as the manner in which the second element 10 is rotationally connected to the first longitudinal beam 1 of the first bracket 7 described above, and will not be repeated here.

[0051] The other end of the fourth element 12 is rotatably connected to the seventh rod 905. Specifically, a rotation shaft 15 passes through the fourth element 12 and the seventh rod 905, connecting the fourth element 12 and the seventh rod 905, and the fourth element 12 can rotate relative to the rotation shaft 15 and the seventh rod 905. In some embodiments, the fourth element 12 is a telescopic rod, and the length of the fourth element 12 is adjustable. Specifically, the fourth element 12 includes a first rod 1201 and a second rod 1202. One end of the second rod 1202 is inserted into the first rod 1201, and the second rod 1202 can slide relative to the first rod 1201. The fourth element 12 also includes a first locking member 14, the first rod 1201 is provided with a first threaded hole 1203, and the first locking member 14 is threadedly connected to the first threaded hole 1203; by rotating the first locking member 14, one end of the first locking member 14 can pass through the first threaded hole 1203 and abut against the second rod 1202, so as to achieve locking of the first rod 1201 and the second rod 1202. In some embodiments, the first unit also includes a ninth plate 16, which is fixedly connected to the third rod 901 and the fourth rod 902.

One end of the T-shaped second locking member 17 passes through the arc-shaped groove 1601 and is threadedly connected to the second threaded hole 1204. The second locking member 17 is rotated and abuts against the ninth plate 16. The friction between the second locking member 17 and the ninth plate 16 increases, so that the fourth element 12 cannot rotate relative to the seventh rod 905, thereby achieving the locking of the fourth element 12 and the seventh rod 905.

[0052] In some embodiments, the first connecting assembly further includes a pedal 18, which is fixedly connected to the first unit. Specifically, the pedal 18 is welded to the first unit to facilitate a person standing on the pedal 18 to work. In some embodiments, the pedal 18 is shaped like a triangle or a trapezoid.

[0053] In this application, the second element 10, the third element 11, and the first bracket 7 form a triangle, and the second element 10, the fourth element 12, and the display screen form a triangle, so that the display screen back support frame provides stable and reliable support for the display screen 100. The fourth element 12 is rotatably connected to the first element 9, and the position of the fourth element 12 can be adjusted according to the splicing angle between the display screens, thereby achieving support for the spliced ​​curved display screens 100 by the display screen back support frame.

[0054] In some embodiments, the display back support frame further includes a second connecting assembly, which has the same structure as the first connecting assembly. Specifically, the second connecting assembly also includes a first element 9, a second element 10, a third element 11, and a fourth element 12. The connection method between the second element 10, the third element 11, and the fourth element 12 of the second connecting assembly and the first element 9 is similar to the connection method between the second element 10, the third element 11, and the fourth element 12 of the first connecting assembly and the first element 9, and will not be repeated here. One end of the second element 10 is rotatably connected to the second longitudinal beam 2 of the second bracket 8; one end of the third element 11 is rotatably connected to the first longitudinal beam 1 of the second bracket 8; and one end of the fourth element 12 is rotatably connected to the second longitudinal beam 2 of the first bracket 7. The connection method between the second element 10, the third element 11, and the fourth element 12 and the first longitudinal beam 1 or the second longitudinal beam 2 is similar to the connection method between the second element 10 of the first connecting assembly and the first longitudinal beam 1 of the first bracket 7, and will not be repeated here.

[0055] In some embodiments, the display back support frames can be spliced ​​not only along the width of the display screen 100 but also along the height of the display screen 100. For two adjacent frames in the height direction of the display screen 100, one end of the third connector 19 is inserted into the first longitudinal beam 1 or the second longitudinal beam 2 of one frame, and the other end of the third connector 19 is inserted into the first longitudinal beam 1 or the second longitudinal beam 2 of the other frame, thereby connecting the two frames in the height direction of the display screen.
