[0033] Working principle: The sliding and pulling rolling shutter door of the present application is designed based on a cylindrical winding wheel. Since the outer diameter of the cylindrical winding wheel remains unchanged, the pulling force of the pulling wire is not affected during the winding and unwinding process of the pulling wire on the cylindrical winding wheel. However, the rolling shutter is wound on the vertical shaft of the rolling shutter in circles, and the vertical shaft of the rolling shutter and the cylindrical winding wheel rotate synchronously. During the winding and unwinding process of the rolling shutter on the vertical shaft of the rolling shutter, the number of windings or layers of the rolling shutter changes. As the number of windings of the rolling shutter increases or decreases, the pulling force of the rolling shutter is affected. Therefore, when the rolling shutter door is pushed and pulled, there will be a problem that the winding speed of the rolling shutter is inconsistent with the unwinding speed of the pulling wire on the winding drum. The sliding rolling shutter door of the present application is provided with a wire compensator on the basis of a cylindrical winding wheel. The addition of the wire compensator can compensate for the wire of the sliding rolling shutter door to solve the problem of looseness of the sliding rolling shutter door caused by the inconsistency between the pulling speed of the rolling shutter door and the unwinding speed of the wire on the winding drum of the sliding rolling shutter door.
