The square shaft of the motor penetrates the square through hole and extends into the insertion space between the connecting part and the fixing plate 30, and then the cotter pin is inserted into the pin hole. When the motor is started, the square shaft is fixed in the square through hole and can not rotate relatively, so that the roller shutter rod connected with the motor rotates. The length of the insertion space should be greater than that of the square shaft to avoid the fixing plate 30 clamping the motor due to installation error to increase the resistance of the system. Further in a preferred embodiment, the fixing plate 30 is also provided with a square hole which is aligned with the square through hole of the connecting portion so that the overlong square shaft can penetrate through the fixing plate 30.

Referring to fig. 4, the wind-proof rolling shutter balancer structure connected to the tail end is provided with a tail end bracket 50 on the fixing plate 30, a bearing 51 is provided between the fixing plate 30 and the tail end bracket 50, a bracket through hole is provided on the tail end bracket 50, and the bracket through hole is communicated with an inner through hole of the bearing 51.

The tail bracket 50 is connected to the fixing plate 30 by bolts. The connection shaft of the tail end is fixed in the inner through hole of the bearing 51 through the bracket through hole so that the tail end of the roll pipe 61 can freely rotate.

Referring to fig. 11, the wind-proof rolling shutter according to the present embodiment includes a rolling pipe 61, a curtain cloth, a lower rail, two mounting blocks 62, two side rails, and two wind-proof rolling shutter balancers, wherein two ends of the rolling pipe 61 are respectively mounted on the mounting blocks 62 through the wind-proof rolling shutter balancers, the lower rail is fixed to the bottom edge of the curtain cloth, and two side edges of the curtain cloth respectively slide along the side rails.

One end and the drive arrangement of reelpipe 61 are connected, and drive arrangement includes motor 71 and rolls up curtain pole 70, and motor 71 is connected with the one end of rolling up curtain pole 70, and the square shaft of motor 71 is connected with fixed plate 30, rolls up and is equipped with crown 72 with reelpipe 61 inboard connection on the curtain pole 70. Since the square shaft of the motor 71 is fixed on the fixing plate 30, the motor 71 can drive the roller shutter rod 70 to rotate, so that the crown 72 on the roller shutter rod 70 drives the roller tube to rotate.

The other end of the roll pipe 61 is connected with the tail plug 80, the tail plug 80 is inserted into one end of the roll pipe 61 to be fixed, and the tail plug 80 is provided with a connecting shaft which is installed on the fixing plate 30. When the rolling pipe 61 rotates under the action of the driving device, the tail plug 80 is driven to rotate, the connecting shaft of the tail plug 80 is fixed on the fixing plate 30 through the bearing 51, and the position of the sliding assembly on the sliding chute 11 cannot be influenced.

The wind-proof roller shutter has the following operation principle:

when the curtain cloth is pulled down and extends into the two side rails from the roller pipe 61, the cloth on the roller pipe 61 is less and less, so that the outer pipe diameter of the roller pipe 61 is reduced, the roller pipe 61 can automatically move towards the direction close to the side rails along the sliding groove 11 under the pulling force of the curtain cloth, so that the direction that rubber strips on the two sides of the curtain cloth enter the side rails is always perpendicular to the side rails, the curtain cloth is prevented from entering the side rails at an angle, and the friction between the curtain cloth and the side rails is reduced. Similarly, when the curtain cloth is lifted, more and more cloth is distributed on the roller pipe 61, so that the outer diameter of the roller pipe 61 is increased, and the sliding assembly can move along the sliding groove 11 in the direction away from the side rails. The friction between the curtain cloth and the side rails is effectively reduced by using the windproof rolling curtain balancer, so that a low rail with large weight is not required to be arranged, the load of the motor 71 is lightened, and the service lives of the motor 71 and the whole windproof rolling curtain are prolonged.
