Problems solved by technology

Due to the large deformation of the tension cloth under the action of wind load, the door curtain will be detached from the track, thus losing the function of blocking indoor and outdoor air
At present, the usual wind-resistant method is to widen the door body in the track and increase the self-weight of the bottom beam.
However, there are defects in this treatment method: when the door span is large, the wind resistance effect is not ideal
And most importantly, the door body tension cloth is easy to fall off from the door body under the action of wind load, thus causing damage

Abstract

The invention belongs to the technical field of industrial quick roller shutter door tools, and in particular relates to an anti-release mechanism of a flexible quick roller shutter door. The anti-release mechanism of the flexible quick roller shutter door comprises a track, wherein a sliding rail is arranged in one end of the track; an edge row chain is clamped into the sliding rail and is fixedly connected with door body tension cloth; the other end of the track is clamped into a track clamping piece. The anti-release mechanism of the flexible quick roller shutter door can be used for preventing the door body tension cloth from being released from a door body under the action of larger wind load, and is simple in structure and reasonable in design.

Description

technical field [0001] The invention belongs to the technical field of industrial fast rolling door appliances, in particular to a fall-off prevention mechanism for a flexible fast rolling door. Background technique [0002] Flexible fast rolling doors are widely used in the passages of clean workshops such as food and medicine. The door body of the flexible fast rolling door is a tension cloth. Due to the large deformation of the tension cloth under the action of wind load, the door curtain will be detached from the track, thus losing the effect of blocking indoor and outdoor air. And the common wind-resistant method that adopts at present is to widen the door body in the track and increase bottom beam self-weight. However, there are defects in this treatment method: when the span of the door body is large, the wind resistance effect is not ideal. And most importantly, the door body tension cloth is easy to fall off from the door body under the action of wind load, thus ...
