Windproof roller shutter door

Abstract

The invention relates to a windproof roller shutter door. The windproof roller shutter door comprises a roller shutter shaft arranged at the top of a door frame, a soft door curtain and a drive motor.The drive motor drives the roller shutter shaft to wind and unfold the door curtain. Two sides of the door curtain below the roller shutter shaft are correspondingly provided with vertical columns. Each vertical column is correspondingly provided with a sliding sleeve which can slide up and down relative to each vertical column through a transmission mechanism. The sliding sleeve is correspondingly connected with the corresponding bottom of the door curtain. A transmission mechanism is linked with the drive motor. Threading holes arranged at intervals on the upper and lower sides are correspondingly formed in the left and right sides of the door curtain, and tensioning ropes are inserted in the threading holes on each side of the door curtain. The upper ends of the tensioning ropes pass through the corresponding threading holes at the upper part of the curtain correspondingly and are connected with the corresponding position of the roller shutter shaft, and the lower ends of the tensioning ropes pass through the corresponding threading holes at the lower part of the door curtain correspondingly and are connected with the corresponding sliding sleeve. The windproof roller shutter door has the advantages that an integrated support system which is capable of hardness and softness is used, wind resistance and operational reliability are greatly improved; a rope lifting method is used, has no weight problem, and has a lighter dead weight.

Description

technical field [0001] The invention relates to the technical field of rolling door manufacturing, in particular to a flexible rolling door that can be raised and lowered quickly and has strong wind resistance. Background technique [0002] The opening and closing speed of the fast rolling door usually reaches above 0.6m / s. Generally, soft film cloth such as PVC and PVDF is used to make the curtain, and the door opening is opened and closed by winding the curtain through the rotation of the reel or drum. Compared with other industrial doors such as metal rolling doors, lifting doors, and sliding doors, fast rolling doors combine the advantages of fast opening speed, light weight, and high degree of automation, but also have the outstanding disadvantage of weak wind resistance. It is used in outdoor and semi-outdoor Workplaces are severely restricted.

AI Technical Summary

Problems solved by technology

However, this technology must use PVC strips that are as thick as the side chains, which will greatly increase the winding diameter and the space occupied by the top, and the processing technology of structural parts such as track clips and door curtains is also relatively complicated, which greatly affects the practicability

Therefore, the technical scheme of the wind-resistant design of the fast rolling door is not ideal and needs to be improved.
