Description

Technical Field

[0001] The present invention relates to the technical field of rolling curtains, and particularly relates to an adjustable sleeve coupling for a windproof curtain. Background Art

[0002] Around the glass facades, return galleries, halls, etc. of commercial buildings, large-format rolling curtains are required for shading, light blocking, or wind blocking. The working principle of existing large-format rolling curtains is that the large-format rolling curtain is formed by splicing two or more rolling curtains. Brackets and rollers are installed at the upper end of the rolling curtain. The rollers are driven to rotate by a driving motor to realize the winding or unfolding of the rolling curtain. A coupling is arranged between each roller, and each rolling curtain is driven to rotate by the same driving motor to achieve synchronous transmission of the large-format rolling curtain.

[0003] The existing technology has the following disadvantages:

[0004] 1. The running synchronism is difficult to control. When assembled on the wall, it is very easy to encounter the situation of uneven wall surface. As a result, when each roller is installed on the wall, there will be a situation of uneven distance from the wall surface, affecting the flatness of the rolling curtain. After installation, the rollers of rolling curtain A and rolling curtain B may not be on the same straight line or on the same horizontal line, which will make the rolling curtain fabric uneven, resulting in asynchronous stretching or folding of the rolling curtain at various places.

[0005] 2. It affects the construction speed and increases the installation cost. After the brackets and rollers are installed, there will be a height difference b between rolling curtain A and rolling curtain B after the rolling curtain is unfolded due to reasons such as uneven wall surface, and the lower plane of the overall rolling curtain cannot be made neat, or the rolling curtain stretches or folds asynchronously. When the rolling curtain is retracted upward, the lower rods of rolling curtain A and rolling curtain B also maintain a height difference H2, which affects the aesthetics and destroys the user's sense of use, and it is difficult to meet the requirements of testing and acceptance, thus affecting the popularization and use of the product. At this time, if the installation of the windproof curtain is adjusted, adjusting the rollers and the brackets of the rollers will seriously affect the construction progress and increase the installation cost.
