Description

Technical Field

[0001] This invention belongs to the field of sliding door technology, and specifically relates to a modular sliding door. Background Technology

[0002] Sliding doors are a common type of door in homes, originating in China and spreading to Korea and Japan through Chinese culture. Initially, sliding doors were only used for bedroom or dressing room wardrobes. However, with technological advancements and diversified decoration methods, their functions and applications have continuously expanded, from traditional panel surfaces to glass, fabric, rattan, and aluminum alloy profiles, and from sliding doors and folding doors to partition doors. Currently, thermally broken aluminum alloy sliding doors on the market are generally double-leaf or multi-leaf sliding doors, allowing for left and right sliding of both leaves.

[0003] Currently, the installation process of sliding doors requires connecting and fixing various parts with screws, which is inefficient. Furthermore, the hanging rails are exposed during transportation before installation, making them prone to bumps and unevenness, which prevents the door from sliding smoothly. To meet installation needs, a modular sliding door needs to be developed to solve these problems. Summary of the Invention

The first insertion plate 13 is connected to the upper end of the first frame 11. Multiple second one-way racks 14 are connected to the side end face of the first insertion plate 13. The multiple second one-way racks 14 cooperate with the fourth one-way rack 3103 for limiting. The lower end of the first frame 11 is provided with a first insertion slot 12 that cooperates with and is fixed to the ground rail plate 4.

[0064] The second one-way rack 14 is used to engage with the fourth one-way rack 3103 for locking.

[0066] Work process:

[0067] The two ends of the ground track plate 4 are respectively inserted into the first insertion slot 12 and the second insertion slot 26 for connection. The second insertion plate 22 is inserted into the housing 31. The third one-way rack 23 cooperates with the first one-way rack 383 to limit and lock the housing 31 to the second insertion plate 22. The transmission rack 24 cooperates with the transmission gear 323 to rotate the transmission rod 322, which in turn cooperates with the worm gear 324 and the worm wheel 392 to rotate the first connecting plate 393 around the first circular shaft 391. The two ends of the second circular shaft 394 are rotatably connected to the first connecting plate 393 and the slide rail 35 respectively. The second circular shaft 394 moves along the path of the guide hole 34, so that... The slide rail 35 extends along the same path as the guide hole 34, the protrusion 372 enters the locking chamber 25, the protrusion 372 pushes the second push plate 252, the pin 254 passes through the lock hole 373 and inserts into the slot 255, the first insert plate 13 is inserted into the housing 31, the second one-way rack 14 and the fourth one-way rack 3103 cooperate to lock the first side frame mechanism 1 and the housing 31. After the first side frame mechanism 1, the second side frame mechanism 2, the hanging rail mechanism 3 and the ground rail plate 4 are assembled, they are placed in the wall and fixed to the wall by bolts. The sliding door 6 is placed between the slide rail 35 and the ground rail plate 4, thus completing the quick installation of the sliding door.
