Guide mechanism for roller shutter door

Abstract

The utility model relates to the technical field of roller shutter doors, in particular to a guide mechanism for a roller shutter door, which comprises a roller shutter door body serving as a mechanism main body and a rolling mechanism for rolling the roller shutter door body, and two limiting guide mechanisms for preventing two sides of the roller shutter door body from being damaged due to friction are arranged at the bottom of the rolling mechanism. The limiting guide mechanism comprises a stand column, a through hole is formed in the top of the stand column, and rack plates are fixedly connected to the two side walls, located in the through hole, of the stand column. By arranging the limiting guide mechanism, large friction cannot be generated between the roller shutter door body and the guide rail, the roller shutter door body is rolled through the roller shaft, the roller shutter door body drives the fixing rod to move, the gear and the rack plate rotate in a meshed mode, the roller shutter door body is prevented from making contact with the groove face of the stand column, and the service life of the roller shutter door body is prolonged. And the rolling door body is further protected through the multiple balls, so that friction borne by the rolling door body is extremely small, and the service life of the rolling door body is greatly prolonged.
