Curve mechanism for roller shutter door

Abstract

The invention discloses a curve mechanism for a roller shutter door, which comprises two transmission shafts, a spiral pipe or a metal hose is arranged between the two transmission shafts, one or more of a spring, a plurality of balls, a plurality of universal joints or a plurality of synchronous motors is / are arranged in the spiral pipe or the metal hose, the balls are connected in series through a steel wire rope, and the universal joints are connected in series through a steel wire rope. Two ends of the steel wire rope are respectively connected with one end of one transmission shaft; the two ends of the spring are connected with the transmission shaft; the universal joints are connected in sequence, the adjacent universal joints are connected through intermediate shafts, and the universal joints at the two ends are each fixedly connected with one transmission shaft; an angle adjusting block is arranged between every two adjacent synchronous motors, and a rotating shaft of each synchronous motor is connected with one gear. The curve mechanism is wide in application range, curled ascending or descending of the curtain cloth at the bent position, the right angle, the acute angle or the obtuse angle can be achieved, operation is convenient and fast, meanwhile, the roller shutter can bypass an obstacle when the obstacle exists, and large-span installation and curling of one roller shutter can be achieved.

Description

technical field [0001] The invention relates to the technical field of rolling doors, in particular to a curve mechanism for rolling doors. Background technique [0002] Factories, workshops, warehouses, hospitals, and shopping malls are usually equipped with rolling doors. Rolling shutter doors are not only strong and reliable, but also have good durability, and are widely used in the construction field. [0003] Since the existing rolling door reel cannot be bent, the curtain cannot be curled up at curves, right angles, acute angles and obtuse angles. The original technology is provided with one or more rolling doors at the bending or bending, or double-layer rolling doors to realize the rising or rolling of the rolling door. Descending, the curtain does not rotate around the axis of the bend, which is not beautiful, but also wastes materials and is expensive. Contents of the invention [0004] In order to solve the above technical problems, an embodiment of the presen...
