[0021] First, those skilled in the art should understand that these embodiments are merely used to explain the technical principles of the embodiments of the present application and are not intended to limit the scope of protection of the embodiments of the present application. Those skilled in the art may adjust them as needed to suit specific application scenarios.

[0022] In the description of the embodiments of this application, it should be noted that, unless otherwise specified or limited, the terms "fixed" and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium. Those skilled in the art will understand the specific meanings of the above terms in the embodiments of this application based on the specific circumstances.

[0023] The present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] See also Figures 1-5 As shown, an embodiment of the present application discloses a shower room linkage sliding door mechanism, including a rectangular door frame, the door frame including two vertical frames 20 symmetrically arranged on the left and right and two upper guide rails 4 and lower guide rails 10 symmetrically arranged on the top and bottom. In this structure, the vertical frames 20 and the upper guide rails 4 and lower guide rails 10 are all made of aluminum profiles, which have beautiful appearance, are easy to form and are light in weight.

[0025] The door frame is equipped with a fixed door 1 and a movable door. The movable door can be on the left or right side of the fixed door 1, allowing the door to open left or right. In this embodiment, in order to further reduce the area occupied by the movable door when it is opened and overlaps with the fixed door 1, thereby increasing the area of ​​the entry and exit passage, the movable door is divided into a two-part structure. The movable door includes a driving door 3 and a driven door 2, and a linkage assembly is provided between the driving door 3 and the driven door 2. When the driving door 3 moves left or right, the driven door 2 can move synchronously with the driving door 3 under the action of this linkage assembly, thereby improving the efficiency of opening and closing the door. Moreover, in this structure, when the movable door is fully opened, the fixed door 1, the driven door 2, and the driving door 3 are stacked together from the inside out in the direction of the door thickness, freeing up more space for entry and exit, making it easier for people to move around.

[0026] When the door 3 is driven and the driven door 2 is moved left and right, the first pulley 7 and the second pulley 9 are slidably fitted in the upper pulley groove 5.

[0027] On the other hand, in this embodiment, see the attached Figure 3 A downward-facing lower pulley groove 11 is provided on the lower rail of the door frame. Third fixing seats 12 are provided at both ends of the bottom of the driving door 3. Third pulleys 13 are connected to both third fixing seats 12. Fourth fixing seats 14 are provided at both ends of the bottom of the driven door 2. Fourth pulleys 15 are connected to both fourth fixing seats 14. The two third pulleys 13 and the two fourth pulleys 15 are simultaneously slidably mounted within the upper pulley groove 5. In this structure, the downward-facing lower pulley groove 11 on the lower guide rail 10 is primarily designed to prevent water accumulation. Furthermore, this structure is difficult to clean and prone to mold and odor. Corresponding third and fourth pulleys 13 and 15 are also provided at the lower ends of the driving door 3 and driven door 2 to ensure the flexibility and stability of the movable door structure during left and right movement.

[0028] Preferably, the first fixed seat 6 and first pulley 7 at the upper end of the driving door 3 and the third fixed seat 12 and third pulley 13 at the lower end are all identical in structure, and the second fixed seat 8 and second pulley 9 at the upper end of the driven door 2 and the fourth fixed seat 14 and fourth pulley 15 at the lower end are all identical in structure, so that the driving door 3 and the driven door 2 can be installed in the door frame at the upper and lower ends to achieve left-hand or right-hand opening. That is, the driving door 3 and the driven door 2 in this structure have the same structural form at the upper and lower ends. Depending on whether the user wants to open the door left or right, the driving door 3 and the driven door 2 can be easily swapped at the upper and lower ends during installation, which is very convenient and does not require the replacement of other parts. Of course, when the door opening direction is switched, the position of the fixed door 1 in the door frame needs to be adjusted left and right.

[0029] In the above structure, in order to facilitate the operation of the driving door 3 to move left and right, a handle 16 is provided in the middle of the driving door 3 away from the driven door 2.

[0030] In addition, in the above embodiment structure, regardless of whether the door opens to the left or the right, when the sliding door is in a fully closed state, the adjacent doors are sealed and waterproof. Specifically, a first sealing stop is provided at the outer end of the fixed door 1 on the side close to the driven door 2, a second sealing stop is provided at the inner end of the driven door 2 on the side close to the fixed door 1, a third sealing stop is provided at the outer end of the other side of the driven door 2, and a fourth sealing stop is provided at the inner end of the driving door 3 on the side close to the driven door 2. When the sliding door is fully closed, the first sealing stop is in contact with the second sealing stop, and the third sealing stop is in contact with the fourth sealing stop. The sealing stops in this structure can not only achieve sealing and water blocking, but also limit the left and right movement limit positions of the movable door part. Preferably, the first sealing stop, the second sealing stop, the third sealing stop and the fourth sealing stop are all provided along the side wall of the corresponding door structure from top to bottom to better ensure waterproof performance.

[0031] Of course, in this embodiment, a vertically extending rib 22 is also required to be provided between the vertical frame 20 corresponding to the door frame on the side of the driving door 3 away from the driven door 2. The rib 22 here is preferably made of rubber material, which can not only be used for waterproofing, but also play a buffering and shock-absorbing role when closing the door.

[0032] In this embodiment, see the attached Figure 4 The linkage assembly involved includes a first rack 17, a second rack 18, and a drive gear 19. The drive gear 19 is horizontally rotatably connected to the second fixed seat 8 on the side of the driven door 2 away from the fixed door 1. The first rack 17 is horizontally connected between the two first fixed seats 6. Specifically, a horizontally extending fixed plate 21 is connected between the two first fixed seats 6. The side wall of the fixed plate 21 is provided with a mounting groove extending along its length. The non-toothed end of the first rack 17 is fitted into the mounting groove. In addition, the second rack 18 is horizontally connected to the upper guide rail 4 and is located above the upper pulley groove 5. The first rack 17 and the second rack 18 are respectively engaged with the two sides of the drive gear 19. When the driving door 3 moves left or right, the first rack 17 moves left or right with it, driving the drive gear 19 to move left or right between the first rack 17 and the second rack 18, thereby achieving the synchronous left and right movement of the driven door 2 following the driving door 3. More specifically, during the synchronous closing process of the driven door 2 and the driving door 3, when the driving door 3 moves to one side to abut against the vertical side frame 20 on one side of the door frame, the driven door 2 also moves to a fully closed state, that is, the two sides of the driven door 2 move to a position where the corresponding sealing strips between the fixed door 1 and the driving door 3 abut against each other. The same is true when the movable door is opened. As the driving door 3 moves toward the fixed door 1, the driven door 2 also slides synchronously toward the fixed door 1, effectively improving the efficiency of opening and closing the movable door.
