Double-track inorganic folding fireproof shutter door

Abstract

The invention discloses a double-track inorganic folding fireproof shutter door, which comprises a door body. A cavity is formed in the door body; a through groove is formed in the inner bottom wall of the cavity; walls are fixedly connected to the left and right side faces of the door body correspondingly; and two sets of symmetrical first threaded grooves are formed in the inner side wall of thecavity and each comprise the two corresponding first threaded grooves. According to the double-track inorganic folding fireproof shutter door, the effect of simultaneous lifting of the double-track inorganic folding fireproof shutter door is achieved, the simpleness and practicality of the double-track inorganic folding fireproof shutter door are guaranteed, the problem that an existing fireproofshutter door is complex in operation is solved, the advantages of simpleness and practicality are achieved, the effect that the double-track inorganic folding fireproof shutter door is convenient toreplace is achieved, fireproof performance of the double-track inorganic folding fireproof shutter door is guaranteed, the problem that the existing fireproof shutter door is not replaced for a long time, and consequently the using effect is poor is solved, the advantage of convenient tea break replacing is achieved, and wide promotion is facilitated.

Description

technical field [0001] The invention relates to the technical field of rolling doors, in particular to a double-track inorganic folding fireproof rolling door. Background technique [0002] Rolling shutter doors are connected in series with 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. It consists of curtain panels, seat panels, guide rails, and supports. , reel, box, control box, door roller, limiter, door lintel, manual quick release switch device, button switch and safety device, etc., generally installed in places where it is inconvenient to use walls to separate. [0003] The rolling shutter door plays the role of horizontal separation like the wall. The rolling shutter door is a telescopic shed type, which has the characteristics of stable opening and closing and small space after opening. The current fireproof rolling door is complicated to i...
