Description

Supplementary anti-falling device of rolling slats door

Technical Field

The utility model relates to a rolling slats door auxiliary device, concretely relates to supplementary anti-falling device after manual rolling slats door and electric rolling slats door rise.

Background

The rolling door comprises a manual rolling door and an electric rolling door, and the manual rolling door can manually pull the rolling door up and down by means of balancing force of a torsion spring on a scroll; the special motor for the electric roller shutter door drives the scroll to rotate, further drives the roller shutter to lift up and down, and the roller shutter automatically stops when the roller shutter reaches the upper limit and the lower limit set by the motor. The falling prevention of the manual rolling door is realized by a torsion spring; the anti-falling of the electric rolling door is realized by an anti-chain-breaking mechanism in the transmission mechanism. Although the anti-falling structure is arranged, the anti-falling structure can still fall down after long-term use, for example, the manual rolling door falls down after rising due to insufficient torsional spring force, and the rolling door falls down due to the damage of the anti-falling mechanism of the large electric rolling door.

Therefore, there is a need for an auxiliary anti-falling device for a roller shutter door, which can support a damaged roller shutter door when temporarily opened, and can protect the roller shutter door when falling down, thereby avoiding safety accidents.
