Description

Technical Field

[0001] The utility model relates to the field of windproof rolling curtains, in particular to a curtain cloth centering adjustment mechanism. Background Art

[0002] The windproof roller shutter is a roller shutter system that can be used on indoor and outdoor facades. The windproof roller shutter includes a roller shutter box installed on the upper part of the window for rolling up the roller shutter cloth, and guide rails located on the left and right sides of the window. A roller is installed in the roller shutter box, and the curtain cloth is wound on the roller. In addition, a motor is installed in the roller shutter box. When the curtain cloth is unfolded or rolled up, the motor drives the roller to rotate. At this time, the left and right sides of the curtain cloth slide in the guide rails, and the curtain cloth is guided by the guide rails.

[0003] The disadvantage of existing windproof roller shutters is that there are roughly three types of motors on the market, and the lengths of the three motors are different. During installation, motors of different lengths will cause the position of the roller to change, which will cause the curtain to shift. The curtain may not be centered in the roller shutter box, affecting the overall visual effect of the curtain. Due to the high cost of modifying the roller shutter box and the roller, existing windproof roller shutters cannot adapt to different motors and need to be improved. Utility Model Content

[0004] The purpose of the utility model is to provide a curtain centering adjustment mechanism that can adapt to different motors in view of the above problems.

[0005] To achieve the above-mentioned purpose, the utility model discloses a curtain cloth centering adjustment mechanism, including a rolling box, a laterally extending drum is provided in the rolling box, and the curtain cloth is wound on the drum. Its structural characteristics are: a tail plug is installed at one end of the drum, and a motor is provided at the other end of the drum. The tail plug and the motor are both rotatably matched with the rolling box. A crown is mounted on the motor, and a positioning surface for matching the crown is provided on the motor. The crown is inserted in the drum, and a multi-layer adjustment platform is provided on the crown. The length of each layer of the adjustment platform is different, and one of the multi-layer adjustment platforms is pressed against the positioning surface of the motor.

[0006] After adopting the above structure, by selecting adjustment tables of different lengths and cooperating with different motors, the position of the roller in the shutter box can be adjusted to ensure that the curtain on the roller is always centered on the shutter box, thereby improving the overall visual effect of the curtain.

[0007] Regarding the structural form of the adjusting platform, the crown includes a base, and the side of the base is a first-order positioning platform, and the first-order positioning platform is one of the layers of the adjusting platform.

[0008] Regarding the structural form of the adjustment platform, a positioning ring is provided on the side of the base, the positioning ring extends outward, and the end face of the positioning ring is a second-order positioning platform, and the second-order positioning platform is one layer of the adjustment platform.

[0009] Regarding the structural form of the adjustment table, multiple support arms are provided on the end face of the positioning ring, the arrangement shape of the multiple support arms is adapted to the motor, the outer end faces of the multiple support arms are flush, the outer end faces of the support arms are a three-step positioning table, and the three-step positioning table is one layer of the adjustment table.

[0010] Regarding the fixing structure of the crown and the reel, a supporting tube is provided on the other side of the base, and a plurality of fins are provided on the outer wall of the supporting tube. The fins surround the supporting tube and are tightly pressed against the reel.

[0011] Regarding the fixing structure of the crown and the transmission shaft, the motor is provided with a transmission shaft extending toward the reel, a positioning block is provided on the outer wall of the transmission shaft, a positioning groove corresponding to the positioning block is provided on the inner wall of the support tube, and the positioning block is clamped in the positioning groove.

[0012] Preferably, a driving wheel is installed at the outer end of the transmission shaft, and the driving wheel is located in the reel and matched with it. The motor is connected to the shutter box, outputs torque through the transmission shaft, and the reel is meshed with the driving wheel on the transmission shaft.

[0013] To sum up, the beneficial effect of the utility model is that by selecting adjustment tables of different lengths and cooperating with different motors, the position of the roller in the shutter box can be adjusted to ensure that the curtain on the roller is always centered on the shutter box, thereby improving the overall visual effect of the curtain.
