The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
[0031] See also Figures 1 to 8 , which is a frameless hidden pulley sliding door 100 of a preferred embodiment of the present invention, includes a fixing mechanism 10 and a sliding door 20, the fixing mechanism 10 includes a fixing rail 11 provided with shock absorbers 12 at both ends of the fixing rail 11, a guide groove 111 is provided on the side of the fixing rail 11 along the length extension direction, the sliding door 20 is slidably connected to the guide groove 111, and a limiting groove 121 corresponding to the sliding door 20 is provided on the shock absorber 12; it also includes a guide mechanism 30 connecting the sliding door 20 and the guide groove 111, the guide mechanism 30 includes a pulley 31 slidingly matched with the guide groove 111 and a mounting seat 32 connecting the sliding door 20 and the pulley 31, the pulley 31 is provided on one side of the sliding door 20, the mounting seat 32 includes an adjusting block 321 and a connecting shaft 322, the sliding door 20 is provided with an adjusting hole 21 rotatably matched with the adjusting block 321, the connecting shaft 322 is eccentrically arranged with the adjusting block 321, and the connecting shaft 322 is connected to the pulley 31 at one end away from the adjusting block 321.
[0032] The frameless hidden pulley sliding door 100 of the present application is more convenient to install and debug by installing the pulley 31 on the side of the top of the sliding door 20 and correspondingly opening the guide groove 111 on the side of the fixed rail 11. The relative height of the pulley 31 and the sliding door 20 can be fine-tuned by rotating the adjustment block 321. Moreover, during normal use, the pulley 31 can be hidden due to the obstruction of the sliding door 20 and the fixed rail 11, which is more beautiful. Compared with the traditional arrangement of setting the pulley 31 at the top or bottom of the fixed rail 11, the push door in the present application only needs to meet the strength requirements of the fixed rail 11 and open the size of the guide groove 111 that can accommodate the pulley 31, so that the height of the fixed rail 11 can be reduced as much as possible, making the structure of the sliding door simpler and more compact. In addition, the side frame equipped with the traditional sliding door is eliminated, which further saves material costs, eliminates sanitary dead corners, and is easy to clean, catering to modern people's pursuit of minimalist frameless style.
[0033] like Figure 3 and Figure 5 As shown, in this embodiment, the opening of the guide groove 111 is formed on the side of the fixed rail 11. To facilitate the insertion of the pulley 31 into the guide groove 111 through the opening, the width of the opening of the guide groove 111 is slightly larger than the diameter of the pulley 31. Furthermore, to prevent the pulley 31 from falling out of the opening during normal use, the bottom of the guide groove 111 should be lower than the bottom of the opening. Furthermore, in this embodiment, the width of the bottom of the guide groove 111 gradually decreases from near the opening to away from the opening. This increases the contact area between the inner wall of the guide groove 111 and the pulley 31, thereby improving the sliding stability of the sliding door 20 during the pushing and pulling process.
[0034] Because the connecting shaft 322 and the adjustment block 321 are eccentrically arranged, when fine-tuning the relative height of the pulley 31 and the sliding door 20 is required, the adjustment block 321 can be rotated to fine-tune the height of the pulley 31. Optionally, the mounting base 32 also includes a fixing plate 323 and a mounting plate 324. The fixing plate 323 is connected to the end of the adjustment block 321 away from the pulley 31, and the mounting plate 324 is connected to the end of the connecting shaft 322 away from the adjustment block 321. At least one pulley 31 is mounted on the mounting plate 324. The diameters of the fixing plate 323 and the mounting plate 324 are larger than the diameter of the adjustment hole 21. The fixing plate 323 and mounting plate 324 prevent the adjustment block 321 from falling out of the adjustment hole 21. Furthermore, to facilitate adjustment of the height of the pulley 31 relative to the sliding door 20, the connecting shaft 322 is connected to the adjustment block 321 via a locking screw 327. To prevent the mounting plate 324 from rotating with the connecting shaft 322 when adjusting the angle of the adjustment block 321, the connecting shaft 322 and mounting plate 324 are rotationally connected. To protect the sliding door 20 and prevent damage to the sliding door 20 when tightening the locking screw 327, a washer 326 is provided on the side of the mounting plate 324 near the connecting shaft 322. Optionally, to facilitate installation of the pulley 31, an extension shaft 325 is provided on the mounting base 32, with its ends connecting the mounting plate 324 and the pulley 31, respectively.
