Referring to fig. 1 to 3, a drawstring type built-in venetian blind hollow glass includes a window frame 10, a manipulator 20, a venetian blind 30, ladder cords (not shown), a shaft 50, a turning traction member 60, and a tensioning mechanism 70. The blind 30 is installed in the window frame 10. The window frame 10 is made of a multi-piece profile. The profiles enclose a cavity around the window frame 10 for the installation of other structural elements. The rotating shaft 50 is installed in the top chamber of the window frame 10, the manipulator 20 and the tensioning mechanism 70 are installed at the side portion of the window frame 10, the tensioning mechanism 70 is located below the manipulator 20, and the ladder cord is wound around the blind 30 and the rotating shaft 50, so that the rotating shaft 50 drives the blind 30 to be turned to the closed or open state through the ladder cord. The tensioning mechanism 70 includes a base 100, a first compression spring 200 and a riding wheel assembly 300, the base 100 is connected to the window frame 10, the base 100 is provided with a vertically arranged slideway 110, the riding wheel assembly is slidably arranged in the slideway 110, the upper end of the first compression spring 200 is connected to the base 100, and the lower end of the first compression spring applies an elastic force to the riding wheel assembly 300. One end of the turning traction piece 60 is sleeved with the rotating shaft 50, the other end is sleeved with the supporting wheel component 300, the middle part of the turning traction piece 60 is connected with the controller 20, and thus, the controller 20 moves, the turning traction piece 60 drives the rotating shaft 50 to rotate, and the opening and closing of the blind 30 can be controlled.

In the above-mentioned pull-rope type built-in hollow glass blinds, one end of the turning-over drawing member 60 is sleeved with the rotating shaft 50, and the other end is sleeved with the idler wheel assembly 300. Since the idler assembly 300 is slidably disposed in the slideway 110 and moves downwards along the slideway 110 under the action of the first compression spring 200, the idler assembly 300 moves downwards to tension the overturning traction member 60, so as to tension the overturning traction member 60. Thus, the first pressure spring 200 applies pressure to the carrier roller assembly 300, so that the turning traction rope sleeved on the carrier roller assembly 300 is always in a good tensioning state, and the turning effect of the blind 30 can be ensured.

In one embodiment, referring to fig. 7 and 8, the idler assembly 300 includes an idler body 310 and an idler seat 320, the idler seat 320 is provided with a mounting cavity 321, and the idler body 310 is rotatably mounted in the mounting cavity 321, so that the idler seat 320 supports and protects the idler body 310. The idler seat 320 is provided with a slide block 322, and the slide block 322 is slidably arranged in the slide way 110. By the cooperation of the sliding block 322 and the slideway 110, the idler seat 320 and the idler body 310 can smoothly move up and down along the slideway 110 under the action of the first pressure spring 200.

In one embodiment, referring to fig. 7, the base 100 is fixed to a side wall of the window frame 10 at one side thereof and provided with a slide rail 110 at the other side thereof.

In one embodiment, and with continued reference to fig. 7, the first compression spring 200 is located in the slide 110, and the slide 110 protects the first compression spring 200 from interference from other structural members.

In one embodiment, as shown in fig. 7, the upper end of the first compression spring 200 is fixed to the top wall of the slide way 110, and the lower end abuts against the sliding block 322.

In one embodiment, as shown in fig. 7, the tensioning mechanism 70 further includes a second compression spring 400 and a rolling element 500, the base 100 is provided with a wedge cavity 120 and a gap 130 communicating with the wedge cavity 120, the wedge cavity 120 is wide at the top and narrow at the bottom, the rolling element 500 is located in the wedge cavity 120, the top end of the second compression spring 400 is fixed on the cavity wall of the wedge cavity 120, and the bottom end abuts against the rolling element 500. The notch 130 is adjacent to the side wall of the window frame 10 so that a portion of the rolling member 500 can be in rolling contact with the side wall of the window frame 10 through the notch 130.

When the conventional tightening mechanism 70 is installed, a hole is drilled in the outer side of the window frame 10, and a fastener is inserted through the drilled hole to connect the window frame 10 and the base 100, thereby fixedly installing the base 100. However, this installation operation not only requires a hole to be drilled, which deteriorates the sealing property of the window frame 10, and is time-consuming and labor-consuming, but also requires precise positioning for drilling to connect the window frame 10 and the base 100 after the fastener is passed through the hole, resulting in great difficulty in drilling.

The technical scheme adopted by the application is that a second pressure spring 400 and a rolling part 500 are installed in the wedge-shaped cavity 120, the second pressure spring 400 is abutted against the rolling part 500, and part of the rolling part 500 can be in rolling contact with the side wall of the window frame 10 through the notch 130. Thus, when the tensioning mechanism 70 is placed into the cavity at the side of the window frame 10 from top to bottom, the tensioning mechanism 70 rolls down along the side wall of the window frame 10 via the rolling member 500 (when the rolling member 500 rotates counterclockwise as viewed in fig. 7) until the rolling member 500 tightens the turnover traction member 60, so that the tensioning mechanism 70 cannot advance any further. This position is exactly where the tensioning mechanism 70 needs to be installed. If the tensioning mechanism 70 is pulled to move upwards, the wedge cavity 120 is wide at the top and narrow at the bottom, and the rolling member 500 is interfered by the second compression spring 400, so that the rolling member 500 cannot rotate clockwise (as seen in fig. 7). Therefore, the tensioning mechanism 70 cannot move upwards, meanwhile, the tensioning mechanism 70 cannot move downwards due to the limitation of the overturning traction piece 60, and the tensioning mechanism 70 can be accurately positioned and fixed without drilling and measuring and positioning in advance, so that the installation is convenient.

In one embodiment, as shown in FIGS. 4-7, the base 100 is provided with a cap 140, the cap 140 being removably mounted to the top of the wedge cavity 120. The top cover 140 is detachable, so that the second compression spring 400 and the rolling member 500 can conveniently enter and exit the wedge-shaped cavity 120, and the second compression spring 400 and the rolling member 500 can be conveniently installed and maintained.

In one embodiment, referring to fig. 7, the riding wheel body 310 is provided with two or more mounting slots 311, the two or more mounting slots 311 are distributed at intervals along the axial direction of the rotating shaft 50, and the mounting slots 311 are used for the socket joint of the turnover traction member 60. In this way, any one of the mounting slots 311 of the turnover traction member 60 can be selected for winding. The overturning traction piece 60 is wound in different mounting grooves 311, the distances between two ends of the overturning traction piece 60 are different, and tensioning adjustment of the overturning traction piece 60 can be realized.

In one embodiment, referring to fig. 4, the everting pull 60 is a pull string or pull bead. Compared with a traction rope, the pull bead has the advantages that firstly, the pull bead is not easy to wear and slide after the use time of the pull rope is long, and effective power transmission is ensured; secondly, the gravity of the pull bead is large, the resistance is large, and the stable power transmission can be ensured.

In one embodiment, with reference to fig. 1 to 4, the rope-pulling type internal venetian blind hollow glass further includes hollow glass, the manipulator 20 includes an inner handle 21 and an outer handle 22, the periphery of the hollow glass is hermetically disposed in the window frame 10, the hollow glass has two layers, the outer handle 22 is mounted on the outer side of the hollow glass, the blind 30 and the inner handle 21 are mounted between the two layers of hollow glass, the inner handle 21 is connected to the turnover traction member 60, and the inner handle 21 and the outer handle 22 are attracted by magnetic force, so that the outer handle 22 and the inner handle 21 are linked.
