Description
Technical Field
The utility model relates to a rolling slats door technical field especially relates to an electric rolling slats door.
Background
The door curtain of the rolling door is formed by connecting a plurality of door sheets in series, and is wound on a winding drum to move up and down along with the winding drum.
As shown in fig. 1, when an existing door curtain is installed, a first door sheet at the top of the door curtain is generally installed and fixed on a winding drum, the firmness of the door curtain and the winding drum is poor, the first door sheet is easily abraded and abraded by friction in the process of winding the door curtain by the winding drum, and after the door curtain is used for a long time, the first door sheet is easily shaken, so that the whole door curtain is dangerous to fall off, and many potential safety hazards exist.
SUMMERY OF THE UTILITY MODEL
In order to solve the defects of the prior art, an electric rolling door is provided.
The utility model provides a technical scheme that its technique was taken is: an electric rolling door comprises a rolling door machine, a transmission mechanism, a supporting plate, a rolling drum, a door curtain and a door curtain guide rail; the transmission mechanism and the supporting plate are respectively fixed above the walls on two sides of the door opening, the transmission mechanism is provided with a transmission chain, one end of the transmission chain is in transmission with the door rolling machine, and the other end of the transmission chain is in transmission with the winding drum; two ends of the winding drum are respectively erected on the transmission mechanism and the supporting plate; the door curtain guide rails are vertically arranged on the walls on the two sides of the door opening; the door roller is arranged on the transmission mechanism and drives the winding drum through the transmission chain; the door curtain is wound on the winding drum through the transition piece and can move up and down along the door curtain guide rail, the transition piece is in a sheet-shaped long strip shape, the cross section of the transition piece is in a bent bud shape and is tapered clockwise from bottom to top, a clamping groove is formed in the lower portion of the transition piece and is used for being clamped and fixed with a first curtain piece of the door curtain, the transition piece is provided with an inner curved surface and an outer curved surface, and the inner curved surface is tightly attached to the outer surface of the winding drum and fixed with the winding drum; when the outer curved surface is used for rolling the door curtain by the winding drum: the first roller layer of the door curtain can be smoothly transited to the second roller layer; the transition piece is also provided with a mounting and fixing hole along the length direction.
The utility model has the advantages that: the utility model can fix the door curtain on the drum more firmly, and reduce the potential safety hazard of the rolling door falling; when the roller shutter is rolled up by the winding drum, the first roller shutter layer can be smoothly transited to the second roller shutter layer, the first shutter sheet cannot be rocked, the service life of the roller shutter door is prolonged, and the safety performance is improved.
