Hole-free curtain installation structure and curtain

A hole-free curtain installation structure, comprising an upper beam bracket (1) and two installation frame assemblies (2), wherein the installation frame assemblies (2) are symmetrically arranged at both ends of the upper beam bracket (1), respectively;

• the installation frame assembly (2) comprises a housing (3) and a sliding frame component (4) slidably arranged on the housing (3) in a horizontal direction;
• the housing (3) is provided with an adjusting mechanism for adjusting a sliding position of the sliding frame component (4);
• the adjusting mechanism comprises a rotating member (5), an output gear (6), and a transmission component connected between the rotating member (5) and the output gear (6);
• the sliding frame component (4) is provided with a rack (401) meshing with the output gear (6);
• the rotating member (5) is capable of rotating in a circumferential direction thereof and sliding in an axial direction thereof;
• a first compression spring (7) is abutted between the output gear (6) and the rotating member (5);
• the rotating member (5) is provided with a positioning protrusion (501), and the housing (3) is provided with a positioning groove (301) corresponding to the positioning protrusion (501);
• during installation, an external force drives the rotating member (5) to slide axially, so that the positioning protrusion (501) is separated from the positioning groove (301);
• the external force drives the rotating member (5) to rotate circumferentially, and the rotating member (5) drives the output gear (6) to rotate through the transmission component;
• the output gear (6) drives the sliding frame component (4) to slide toward an external wall (10) through the rack (401) until the sliding frame component (4) is abutted against the wall (10);
• and when the external force is released from the rotating member (5), the rotating member (5) slides and resets under an elastic force of the first compression spring (7), so that the positioning protrusion (501) is engaged and positioned with the positioning groove (301) to maintain an abutting force of the sliding frame component (4) against the wall (10).
