AI Technical Summary
The existing fixed structure of fireproof roller shutters is prone to causing the rotating rod to be not securely fixed, which may lead to the risk of the roller shutter falling and affect its safety performance.
The roller shutter adopts a locking structure with an arc-shaped internal gear and an external gear. The rotating motor drives the threaded rod to move the transverse plate and the lifting plate to mesh with the gear, thereby achieving a stable lock on the winding disc and preventing the roller shutter from falling.
This improves the stability of the roller shutter door, avoids the risk of it falling due to insecure fixing, and enhances its safety and reliability.
