Roll mosquito net with adjustable spring tension

摘要

The present invention relates to a roll screen that is installed on a window frame of a building and operates to open and close, and the guide frame 300 of the insect screen 100 is installed on both sides of the housing frame 200, and the housing frame 200 is installed with a shaft. The winding rod 10 is installed to be elastically supported by the spring 12, and the insect screen 100 is lifted and opened by the rotation of the winding rod 10 to constitute a tension adjustment member 2, but the tension adjustment member (2) The rotating body 14 and the supporting body 16 are inserted into and coupled to the protrusion 10c formed on the inside of the winding rod 10 through the respective coupling grooves 14b and 16b, but the rotating body 14 is a spring as a direct connection. The spring adjuster 8 and the support 16 are coupled to rotate freely with each other while being integrally connected with the spring adjuster 8 that shaft-couples the other support 16 through (12), and the spring adjuster 8 and the support 16 are coupled to rotate freely with each other. (8) is configured to be fixedly inserted into the shaft hole (4a) formed in the fixing bracket (4) for coupling and supporting the housing frame (200), and the rotating body (14) inserted into the winding rod (10) through the spring adjuster (8) ) is configured to adjust the tension of the winding rod 10 for lifting and opening the insect screen 100 while the spring 12 is torsional and compressed by interlocking rotation with each other.
