Description

technical field

[0001] The invention relates to an automatic invisible screen window, in particular to a safety deceleration device for an automatic invisible screen window. Background technique

[0002] At present, the automatic invisible screen window adopts a spring rewinding device. After the gauze is pulled out by the tension beam, the torsion spring placed in the gauze box will generate a certain degree of rewinding force, and the automatic invisible screen window relies on the gauze box. The rewinding force generated by the spring will rewind the gauze into the gauze box for storage when the gauze is not in use. Due to the strong rewinding force generated by the spring, the tension beam at one end of the gauze will always be in contact with the gauze box when the gauze is put away. The yarn outlet of the casing collides quickly, causing the gauze to be impacted. In addition to long-term use, it will cause damage to the gauze, the tension beam and the gauze box, becaus...
