The present embodiment is a multi-panel display device, and the specific structure thereof is shown in fig. 1-8.

As shown in fig. 1, the multi-screen display device includes a first bezel 11 and a second bezel 12. The first clamping frame 11 and the second clamping frame 12 are used for synchronously clamping the screen to be expanded from two sides respectively. The first clamping frame 11 is provided with a first split screen 91 which can be opened and closed in a rotating manner, and the second clamping frame 12 is provided with a second split screen 92 which can be opened and closed in a rotating manner. Two transverse pull rods 21 which are parallel to each other are arranged on the first clamping frame 11, connecting rods 22 corresponding to the transverse pull rods 21 are arranged on the second clamping frame 12, and the connecting rods 22 correspond to the transverse pull rods 21 one by one. In other embodiments, only 1 tie rod may be provided, but the connection stability may be slightly poor. The tie rod 21 is inserted into the connecting rod 22 along one end in the longitudinal direction of the connecting rod 22 and slidably connected to the connecting rod 22. The first clamping frame 11 is connected with the second clamping frame 12 through a cross pull rod 21 and a connecting rod 22. The clamping width of the first clamping frame 11 and the second clamping frame 12 is adjustable, and the clamping width adjusting direction is the mutual sliding direction of the tie rod 21 and the connecting rod 22. The upper connecting rod 22 is provided with two hanging lugs 221, and the hanging lugs 221 are used for hanging the whole multi-screen display device on the upper edge of the screen to be expanded. A cushion (not shown) is provided inside the hanging ear 221 to avoid scratching the screen. A vertical slot 111 with a lateral opening is arranged on the side of the first clamping frame 11 facing the second clamping frame 12, and the vertical slot 111 is used for buckling on the left side of the screen to be expanded. An upper clamping opening 121 and a lower clamping opening 121 are arranged on the side edge of the second clamping frame 12 facing the first clamping frame 11, and the clamping openings 121 are used for buckling on the right side edge of the screen to be expanded.

As shown in fig. 2, two screw holes 211 and an elongated positioning hole 212 are formed at both ends of the tie rod 21 in the longitudinal direction. The positioning hole 212 is disposed between the two screw holes 211 and the connection line of the two screw holes 211 is perpendicular to the length direction of the positioning hole 212. The positioning plate 112 is disposed inside the first clamping frame 11, and the positioning plate 112 is inserted into the positioning hole 212 during assembly, so as to fix the relative position of the tie rod 21 and the first clamping frame 11. In addition, a limit groove 213 extending along the length direction of the tie rod 21 is formed in one long side of the tie rod 21, a corresponding limit screw 222 is screwed into the connecting rod 22, and the limit screw 222 penetrates into the space of the limit groove 213.
