A first clamping portion 41 is arranged on one side of the screen window 4, and a second clamping portion 42 is arranged on the other side of the screen window 4. One end of the first clamping portion 41 protrudes towards one side surface of the screen window 4, and the other end of the first clamping portion 41 is bent reversely towards the other side of the screen window 4 to form a hook shape. One end of the second clamping portion 42 protrudes towards the other side surface of the screen window 4, and the other end of the second clamping portion 42 is bent reversely towards one side of the screen window 4 to form a hook shape. On one side of the connecting rod 5, a first slot 51 and a second slot 52 with one side open are arranged at intervals along the width direction thereof, and the length directions of the first slot 51 and the second slot 52 are the same as the length direction of the connecting rod 5. The outer side wall of the open side of the first slot 51 is bent towards the inside of the slot, and the outer side wall of the open side of the second slot 52 is bent towards the inside of the slot. The hook end of the first clamping portion 41 is clamped in the first slot 51, and the hook end of the second clamping portion 42 of another adjacent screen window 4 is clamped in the second slot 52. The transmission module 6 is used to drive multiple screen windows 4 to slide simultaneously.

A first clamping portion 41 and a second clamping portion 42 are respectively arranged on both sides of the screen window 4, and a first slot 51 and a second slot 52 with openings are correspondingly arranged on both sides of the connecting rod 5. The hook end of the first clamping portion 41 is clamped in the first slot 51, and the hook end of the second clamping portion 42 of another adjacent screen window 4 is clamped in the second slot 52. When the screen window 4 is folded and rotated, it rotates around the connecting rod 5 with the hook end as the axis and is restricted in the corresponding slot, which is convenient for installation and disassembly, improves the stability of the connection structure, effectively prevents the phenomenon of unhooking, and is more convenient to use.

[0034] In this embodiment, please refer to Figure 3 and Figure 8, the first clamping portion 41 and the second clamping portion 42 are arranged with the same structure, and the first clamping groove 51 and the second clamping groove 52 are arranged with the same structure, which has a simple structure and saves costs. The lengths of the first clamping portion 41 and the second clamping portion 42 are the same as the length of the screen window 4.

[0035] The hook ends of the first clamping portion 41 and the second clamping portion 42 are arranged in an arc structure, and the opening widths of the first clamping groove 51 and the second clamping groove 52 are both smaller than the arc radius of the hook end, making the folding and rotation more convenient. Specifically, the bent portions of the outer side walls of the first clamping groove 51 and the second clamping groove 52 towards the inside of the groove are arranged at an acute angle with the inner wall of the groove, and the bent portions are arranged in a plate-like structure, which can prevent the screen window 4 from disengaging from the corresponding clamping groove during the rotation process.

The sides of the first joint 61 and the second joint 62 are both provided with a third clamping groove 64 having the same structure as the first clamping groove 51 and a fourth clamping groove 65 having the same structure as the second clamping groove 52. The third clamping portion 71 of the aluminum plate 7 is clamped in the third clamping groove 64, and the fourth clamping portion 72 of another adjacent aluminum plate 7 is clamped in the fourth clamping groove 65, so that the aluminum plate 7 can be rotated and folded, thereby improving the rigidity of the folding screen 4.

[0040] Please refer to Figure 7 The transmission module 6 also includes a third joint 63. The two ends of the connecting rod 5 between the two adjacent first joints 61 are provided with a third joint 63, and the third joint 63 is arranged on the side of the screen 4 away from the first joint 61, so that the structural connection of the two adjacent screens 4 is more stable.

[0041] The end of the third joint 63 is spaced apart from the upper rail 2 or the lower rail 3 for easy folding and rotation. Moreover, a third slot 64 and a fourth slot 65 are also provided on one side of the third joint 63 connected to the aluminum plate 7 for easy installation and fixing of two adjacent aluminum plates 7.
