[0036] Embodiment 1

[0037] This embodiment provides a fixing device 100 for a screen box, as Figure 1-6 shown, including: a first groove 1, which is used to accommodate the end of the pulling beam. At the same time, the space formed by the first groove 1 is communicated with the space of the screen window guide rail, so as to realize the reciprocating movement of the pulling beam to traction the screen between the first groove 1 and the space of the screen window guide rail;

[0038] a positioning mechanism 2, which is used to cooperate with the hook structure at the end of the rolling curtain box to fix the rolling curtain box to prevent the rolling curtain box from moving when the screen is reciprocally moved by the pulling beam. The positioning mechanism 2 is arranged on one side (the right side in Figure 2) of the first groove 1 facing the end of the rolling curtain box. The specific structural form of the positioning mechanism 2 can be various. In this embodiment, the positioning mechanism 2 is a first U-shaped card slot with an opening facing the thickness direction of the pulling beam (the opening in Figure 2 faces the direction of the cover plate). The first U-shaped card slot realizes the fixation of the screen box by cooperating with the hook structure at the end of the rolling curtain box.

[0039] In order to further enhance the aesthetics of the screen box fixing device and the stability of fixing the screen box, the screen box fixing device further includes a cover plate 4 covering the screen box fixing device and a cavity 5 accommodating the cover plate rotation structure.
