Double-track inorganic fireproof rolling shutter door

Abstract

The invention discloses a double-track inorganic fireproof rolling shutter door, which comprises a mounting box. The inside of the mounting box is provided with a through-opening. An upper surface ofthe mounting box is fixedly connected with a driving box. The driving box is internally provided with a gear motor. An output of the gear motor is fixedly connected with a first rotating rod. One end,far from the gear motor, of the first rotating rod penetrates an inner side wall of the driving box and extends to the outside of the driving box. One end, far from the driving box, of the first rotating rod is fixedly connected with a first gear. An outer surface of the first gear is sleeved with a toothed chain. A first bearing is fixedly embedded into an inner side wall of the mounting box. Aninner ring of the first bearing is fixedly connected with a second rotating rod. One end, far from the first bearing, of the second rotating rod penetrates an inner side wall of the mounting box andextends to the outside of the mounting box. One end, far from the mounting box, of the second rotating rod is fixedly connected with a second gear. The double-track inorganic fireproof rolling shutterdoor has the advantages of simple structure, long service lifetime and fast adjustment speed.

Description

technical field [0001] The invention relates to the technical field of rolling doors, in particular to a double-track inorganic fireproof rolling door. Background technique [0002] Rolling shutter doors are connected in series by multi-joint movable doors. In a fixed slideway, the upper and lower doors are rotated around the reel above the door. Rolling shutter doors are usually widely used in shops, and are generally installed in places that are inconvenient to be separated by firewalls, such as open doors. Elevator halls, escalators, large business halls of department stores, exhibition halls of exhibition buildings, and parts of buildings with large openings that cannot be used for fire-resistant doors and windows. Fire-resistant shutter doors are widely used in construction projects for fire-resistant partitions. [0003] Fire-proof rolling door is a kind of fire-proof and heat-insulating facility suitable for large openings of buildings. The product plays a certain rol...
