Description

Technical Field

[0001] The utility model belongs to the technical field of rolling curtains, and in particular relates to a lifting and positioning mechanism for a rolling curtain. Background Art

[0002] Roller blinds are a type of window decoration product. The curtain fabric is processed with resin and rolled into a roller shape. It is raised and lowered by a pull rope or chain. It is simple and convenient to operate, and has a beautiful and simple appearance, making the window frame look clean and neat, and the entire room look spacious and simple. Roller blinds mainly include electric roller blinds, bead roller blinds, and spring roller blinds.

[0003] In order to prevent the existing roller blinds from being blown up by the wind and affecting the sunshade effect during use, positioning mechanisms are usually set on both sides of the roller blinds to position the roller blinds. Most of the existing positioning mechanisms are to set slide rails on both sides of the roller blinds, and slide blocks are slidably connected in the slide rails, and then one side of the roller blinds is fixed on the slide block. Although this can achieve a certain positioning effect, when the user forgets to lubricate, friction will be generated between the slide rail and the slide block, resulting in a jam between the slide rail and the slide block. When one side of the roller blind is jammed, if the roller blind is continued to be rolled up, since the length of the bottom of the roller blind is fixed, it will cause the roller blind to tear, thereby causing damage to the roller blind and affecting the normal use of the roller blind.
