Therefore, through the combined action of the driving wheel 141 and the driven wheel 331, the effect of driving the reinforcing plate 32 to slide horizontally and then sliding into the door curtain 3 can be realized. The overall structure is simple and easy to achieve. In this embodiment, the linkage between the reinforcing shaft 13 and the driving wheel 141 is that a sprocket is sleeved on the lower end of the reinforcing shaft 13, and a chain wheel is coaxially sleeved on the lower end surface of each driving wheel 141, and then Each sprocket is connected by a chain, so as to enhance the sliding effect of the driving wheel 141 during the rotation of the rotating shaft 13 .

When the rotation speed of the detection wind wheel 152 reaches a threshold value, the runner 1522 is linked with the linkage wheel 1513, and through the linkage The setting of the gear box 1512 can realize the conversion of the fast rotation of the detection wind wheel 152 into the slow rotation, so as to increase the torque of the output shaft, so that the output shaft can effectively drive the reinforcement shaft 13 to rotate, and through the linkage rod 1521 and the rotation The setting of the wheel 1522 can realize that the output shaft of the linkage gearbox 1512 will output power only when the wind force reaches a relatively large level, so that when a typhoon comes, the wind resistance of the door curtain 3 is enhanced by the sliding of the reinforcing plate 32 Compared with the motor method, it does not need to connect external circuits, which is convenient for maintenance.

As an improved specific embodiment, the upper end surface of the linkage wheel 1513 is provided with linkage teeth, and the wheel edge of the runner 1522 is provided with a number of linkage claws evenly distributed along the wheel edge. One end is elastically hinged with the wheel edge of the runner 1522, so as to be overturned and covered on the wheel edge of the runner 1522. When it is detected that the rotational speed of the wind wheel 152 reaches the threshold value, the linkage claws are opened and connected with the linkage teeth to connect the runner. 1522 is linked with the linkage wheel 1513. Through the above structure, the relationship between the rotational speed and the centrifugal force can be used to realize the linkage between the runner 1522 and the linkage wheel 1513 when the rotational speed of the detected wind wheel 152 reaches the maximum, and the elastic hinge is connected by the torsion spring structure. to achieve, and therefore will not be repeated.

As an improved specific embodiment, the linkage claw and the hinge shaft of the wheel edge of the runner 1522 have a flip-stop position. When the rotational speed of the detected wind wheel 152 reaches a threshold value, the linkage claw flips to the flip-stop position. To open on the wheel edge of the runner 1522, the flip-stop position on the linkage claw in this embodiment is formed by a combination of a convex point and a groove, that is, a hemispherical convex point is set on the linkage claw. , a hemispherical groove is opened at the position of the wheel side hinge column of the runner 1522, and the locking effect is realized by embedding the convex point into the groove. The retaining force of the locking position is mainly through the convex point and the concave. Therefore, when the reinforcing plate 32 slides in place, there will be a great resistance between the driving wheel 141 and the reinforcing shaft 32 and cannot rotate, so the difference between the convex point and the groove on the linkage claw is Deformation will occur during the time, so that the convex point comes out of the groove, and the locking position on the linkage claw is released, so that the linkage claw is separated from the linkage linkage tooth, so that the detection wind wheel 152 will continue to rotate without affecting the linkage wheel 1513.

To sum up, the wind-resistant rolling gate of this embodiment can effectively realize that the reinforcing plate 32 slides into the hollow door curtain 3 when the typhoon weather comes by the combination of the hollow door curtain 3 and the reinforcing plate 32 , thereby enhancing the wind resistance of the door curtain 3 .
