[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.
[0021] The utility model provides a technical solution: Figures 1 to 5 As shown, in this embodiment, a combined assembly structure for a pulley block includes a window 1 and a pulley block body 2. Two pulley block bodies 2 are arranged below the window 1. The pulley block body 2 is composed of a fixed plate 7, a pulley body 8 and an edge plate 9. The number of the fixed plates 7 is two. Two pulley bodies 8 are rotatably connected between the two fixed plates 7. The bottoms of the two pulley bodies 8 are located on the same horizontal plane. The edges of the two fixed plates 7 are fixedly connected with the edge plates 9. The two pulley block bodies 2 Symmetrically distributed on both sides of the bottom of the window 1, the bottom of the window 1 is provided with a mounting groove 3 acting on the pulley block body 2, and two vertically arranged limit plates 4 are fixedly connected to the inner wall of the mounting groove 3, and the two limit plates 4 are symmetrically distributed on both sides inside the mounting groove 3, and a fitting groove 5 acting on the pulley block body 2 is formed between the limit plates 4 and the inner wall of the mounting groove 3, and the front and rear side walls of the mounting groove 3 are provided with steps 6 integrally formed therewith, and a baffle 11 acting on the pulley block body 2 is rotatably installed at the bottom of the step 6.
[0022] Wherein, an annular groove 10 is formed on the outer surface of the pulley body 8 .
[0023] By providing the annular groove 10 , the pulley body 8 can better fit the guide rail on the window frame, so that the window body 1 can move more smoothly.
[0024] Among them, the edge sealing plate 9 is composed of plate No. 12, plate No. 2, plate 13 and plate No. 3, which are distributed in a U shape and are integrally formed between adjacent plates. The length of plate No. 12 is equal to the distance between the limit plate 4 and the inner wall of the mounting groove 3, and the distance between plate No. 12 and plate No. 3, 14 is equal to the height of the step 6.
[0025] With such arrangement, the pulley block body 2 and the fitting groove 5 can be adapted to each other, and no shaking will occur when the pulley block body 2 is inserted into the fitting groove 5.
[0026] Among them, a rotating shaft 15 is rotatably connected at the rotation center of the baffle 11, a locking bolt 16 is inserted in the middle of the rotating shaft 15 and is connected to the locking bolt 16 through threaded cooperation, the locking bolt 16 passes through the rotating shaft 15 and is inserted inside the step 6, and the locking bolt 16 is connected to the step 6 through threaded cooperation.
[0027] When in use, the locking bolt 16 is rotated to control the depth of the locking bolt 16 inserted into the step 6, thereby controlling the tightness of the top cap of the rotating shaft 15 pressing on the baffle 11, and then controlling the resistance encountered by the baffle 11 when rotating. By increasing the resistance, the baffle 11 can be prevented from automatically deviating.
[0028] The utility model provides a combined assembly structure for a pulley block, and the specific working principle is as follows:
[0029] A fitting groove 5 is formed between the limiting plate 4 and the inner wall of the installation groove 3 to act on the pulley block body 2.
