Specific embodiment
As shown in figures 1-4, the embodiment of the utility model, a kind of rolling screen door that can prevent door roller brake failure, including
Supporting plate 1, slot rails 2, reel 3, roller shutter 4, door roller 5, chain-drive mechanism 6, limiter 7 and controller 8；The supporting plate
1 is arranged on both sides above door opening, and guide rail 2 is divided into door opening both sides, and 3 both ends of reel and supporting plate 1 are rotatablely connected, and roller shutter 4 is wrapped in
It can slide up and down on reel 3 and along guide rail 2；The door roller 5 be arranged on door opening one side supporting plate 1 on, the door roller 5 include according to
Gearbox 9, motor 10 and the brake gear 11 of secondary connection, the motor 10 and brake gear 11 are electrically connected simultaneously with controller 8
It is controlled by it；The limiter 7 is arranged on 5 one side of door roller, the limiter 7 and gearbox 9 is sequentially connected and controller 8 is electrically connected
It connects, which is used to control what roller shutter 4 opened the door and closed the door to be automatically stopped position；2 top of guide rail is equipped with through its groove profile
The jack 12 of two sides, 2 side of guide rail are equipped with anti-fall device 13；The anti-fall device 13 includes Anti-dropping rack plate 14, electromagnetism
Iron 15, anti-falling rods 16, spring 17 and microswitch 18；The Anti-dropping rack plate 14 is arranged on 2 upper side of guide rail, and middle part is equipped with
Anti-fall rod bearing 19；The electromagnet 15 is arranged on 14 one end of Anti-dropping rack plate, and the electromagnet 15 and controller 8 are electrically connected；It is described
16 middle part of anti-falling rods is equipped with spring base 20, which slides through anti-fall rod bearing 19 and connect electromagnet 15, another
