[0001] The utility model relates to the technical field of soft curtain doors, in particular to a fireproof and flame-retardant PVC quick soft curtain door. Background Art

[0002] A soft curtain door, also known as a stacking door or a flexible door, is a door that is electrically lifted and lowered. Most soft curtain doors are industrial doors used in large factories. They are stacking doors made of a soft curtain design and have the functions of quick opening and quick closing. At the same time, most quick stacking doors have multiple functions such as heat preservation, fire prevention, insect prevention, sound insulation, and dust prevention.

[0003] However, after long-term use, the surface of the window made of PVC material will be scratched, which affects the line of sight. And in the prior art, it is not easy to replace the window of the soft curtain door after it is scratched. Based on this, the utility model designs a fireproof, flame-retardant and waterproof PVC quick soft curtain door (specifically refer to the patent number: 202221767214.8) to solve the above technical problems. It includes a door head sealing box, side frames and a curtain cloth. The curtain cloth is provided with a counterweight plate. The door head sealing box is provided with a winding device.

The PVC curtain is provided with connecting columns. The anti-wind strips are provided with insertion holes. The connecting columns are connected in the insertion holes. The insertion holes are provided with protrusions. The connecting columns are provided with grooves. The protrusions are clamped in the grooves. By pulling the PVC curtain, the connecting columns are gradually removed from the insertion holes one by one. When installing a new PVC curtain, the connecting columns are inserted into the insertion holes one by one. At the same time, the setting that the protrusions are clamped in the grooves increases the firmness of the connecting columns and the insertion holes. When the PVC curtain is affected by wind, the connecting columns are not easy to slide out of the insertion holes. Through the above settings, it is convenient to disassemble the PVC curtain in the prior art and avoid the problem of being not easy to replace in the prior art.
