Technical Problem

[0004]当施工人员使用电钻等工具在梁体上打洞时，钢筋的存在使得钻孔难度大幅增加，普通钻头极易磨损甚至断裂，需要频繁更换工具，延长施工时间；其次，在钻遇钢筋时产生的剧烈震动和反作用力，可能导致钻头偏移或失控，不仅破坏墙面平整度，还可能对施工人员的手部或身体造成冲击伤害，存在安全隐患

Benefits of technology

[0024] 1. In this utility model, by setting abutment seats and telescopic mounting seats at both ends of the mounting box, when installation is required, simply abut one end of the abutment seat against the inner wall of the window, and adjust the position of the rotating screw sleeve screwed onto the connecting stud by rotating the screw sleeve at the other end, so that the overall length of the telescopic mounting seat gradually increases and abuts against the wall on the other side of the window, thereby completing the installation of the entire roller blind. The structure is simple and easy to install, and the bottom is equipped with a guide rail so that the roller blind will not shake when moving up and down, improving the overall convenience of use.

Abstract

This utility model discloses a built-in roller blind device, belonging to the field of roller blind technology. It includes an installation box containing a roller shaft, on which the roller blind is fitted. A guide rod is provided at the tail of the roller blind; a guide rail installed on the inner wall of the window, with both ends of the guide rod slidably connected within the guide rail; and a telescopic mounting seat connected to one end of the installation box. An abutment seat is provided at the other end of the installation box. This utility model, by providing an abutment seat and a telescopic mounting seat at both ends of the installation box, allows for easy installation. When installation is required, one end of the abutment seat is placed against the inner wall of the window, and the other end is adjusted by rotating a screw sleeve to change its position on the connecting stud. This causes the telescopic mounting seat to gradually lengthen and abut against the wall on the other side of the window, thus completing the installation of the roller blind. The structure is simple, installation is convenient, and the bottom, combined with the guide rail, prevents the roller blind from wobbling during vertical movement, improving ease of use.
