[0038] like Figure 1-12 As shown, a method for adjusting a transmission carrier of an electric curtain comprises the above-mentioned transmission carrier adjustment mechanism of an electric curtain, and the specific processing steps are as follows: Step 1: Fix the mounting base 503 to the wall through expansion screws, then install the curtains below the hanging hooks 205 in sequence, and hang the last connecting piece at the edge of the curtains on the hooks 410 to complete the installation of the curtains. At this time, the motor 201 drives the roller 202 to rotate, so that the transmission belt 203 drives the curtain fabric below the hanging hooks 205 to move, so that the curtains are automatically opened and closed; Step 2: When the transmission belt 203 slips, the edge of the curtain can be pulled so that the edge of the curtain can drive the connecting shaft 406 to move downward, thereby driving the bevel gear 2 408 to mesh with the bevel gear 3 411. At this time, the power of the motor 201 can be transmitted to the bevel gear 1 303 through the bevel gear 2 408, so that the screw 304 cooperates with the threaded hole 1 305, so that the position of the sleeve 101 changes, thereby changing the position of the roller 1 202 and tightening the transmission belt 203. Step three: When maintenance is needed, by rotating the rotating drum 505, the rotating drum 505 drives the threaded hole 2 507 to rotate, so that the threaded hole 2 507 moves along the surface of the bolt 501, so that the bolt 501 is disengaged from the docking tube 502, so that the connecting tube 1 001 and the connecting tube 2 102 can be disassembled without removing the expansion screw in the mounting seat 503.

[0039] In further optimization of the above embodiment, in order to save resources and reduce processing costs, like Figure 1-12As shown, the mounting base 503 is first fixed to the wall using expansion screws, and then the bolt 501 is aligned with the threaded hole 507, and the rotating drum 505 is rotated to make the threaded hole 507 engage with the bolt 501, thereby realizing the installation of the connecting tube 1 001 and the connecting tube 2 102. At this time, the top of the curtain is connected to the cloth hook 205 and the pulley 206, and the last fixing hole at the edge of the curtain is fixed to the hook 410. At this time, if the curtain is to be opened and closed, the motor 201 is controlled to rotate, so that the transmission belt 203 drives the cloth hook 205 and the pulley 206 to move, so as to realize the opening and closing of the curtain. When the transmission belt 203 becomes loose and slips, the edge of the curtain is pulled at this time, so that the edge of the curtain drives the hook 410 moves downward, so that the connecting shaft 406 drives the bevel gear 2 408 to move downward, and at the same time meshes with the bevel gear 1 303 and the bevel gear 3 411, so that the power of the motor 201 can be transmitted to the screw 304, and can move through the threaded hole 1 305, so that the cross fixing plate 302 moves along the connecting cylinder 1 001, thereby driving the motor 201 and the roller 1 202 to move as a whole, so that the distance between the connecting cylinder 1 001 and the roller 2 204 changes, so that the transmission belt 203 is tightened, and the effect of adjusting the transmission belt 203 is achieved. When the adjustment is completed, the edge of the curtain is loosened, and the bevel gear 2 408 is reset by the reset spring 403, interrupting the power transmission of the motor 201, thereby completing the transmission load adjustment of the curtain.

The transmission carrier adjustment mechanism of an electric curtain according to claim 1, characterized in that: The fixing assembly (005) comprises: bolts (501), the bolts (501) being installed on one side of the connecting tube 1 (001) and the connecting tube 2 (102), and two groups of bolts (501) are installed correspondingly, the bolts (501) are connected through the docking tube (502), a mounting seat (503) is welded on one side of the docking tube (502), an annular groove 2 (504) is provided on the surface of the docking tube (502), a rotating tube (505) is sleeved on the docking tube (502), a positioning ring 2 (506) is fixedly connected to the inner wall of the rotating tube (505), the positioning ring 2 (506) is slidably connected to the annular groove 2 (504), a threaded hole 2 (507) is provided on the inner wall of the rotating tube (505), and the threaded hole 2 (507) is threadedly connected to the bolt (501).

10. A method for adjusting a transmission carrier of an electric curtain, comprising the transmission carrier adjustment mechanism of an electric curtain as claimed in any one of claims 1 to 9, characterized in that: The processing steps are as follows: Step 1: The installation base (503) is fixed to the wall by means of expansion screws, and then the curtain is installed below the cloth hook (205) in sequence, and the last connecting piece at the edge of the curtain is hung on the hook (410), so that the installation of the curtain is completed. At this time, the motor (201) drives the roller 1 (202) to rotate, so that the transmission belt (203) drives the curtain cloth below the cloth hook (205) to move, so that the curtain is automatically opened and closed; Step 2: When the transmission belt (203) slips, the edge of the curtain can be pulled so that the edge of the curtain can drive the connecting shaft (406) to move downward, thereby driving the bevel gear 2 (408) to mesh with the bevel gear 3 (411). At this time, the power of the motor (201) can be transmitted to the bevel gear 1 (303) through the bevel gear 2 (408), so that the screw rod (304) and the threaded hole 1 (305) are matched, so that the position of the sleeve (101) changes, thereby changing the position of the roller 1 (202), and tightening the transmission belt (203); Step 3: When maintenance is required, the rotating drum (505) is rotated, and the rotating drum (505) drives the second threaded hole (507) to rotate, so that the second threaded hole (507) moves along the surface of the bolt (501), thereby disengaging the bolt (501) from the docking tube (502), so that the first connecting tube (001) and the second connecting tube (102) can be disassembled without removing the expansion screw in the mounting seat (503).
