[0026] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0027] See also Figures 1-6 A linkage door structure includes a fixed profile 10, an active sliding door 20, and a driven sliding door 30. The fixed profile 10 is provided with a slide rail 110. The driven sliding door 30 is provided with a plurality of driven pulleys 310 arranged along the extension direction of the slide rail 110. The driven pulleys 310 are slidably arranged in the slide rail 110. The active sliding door 20 is provided with a friction profile 40 that is frictionally driven with the driven pulley 310. At least one active pulley 210 is installed on the active sliding door 20 on the left side of the friction profile 40. The active pulley 210 is slidably arranged in the slide rail 110.

[0028] The active sliding door 20 reciprocates between a first position and a second position relative to the fixed profile 10;

[0029] When the active sliding door 20 is located at any position between the first position and the second position, the right lower surface of the friction profile 40 is always in contact with at least one driven pulley 310 .

[0030] The present invention reduces the number of parts and costs by using a shared rail for the active pulley and the driven pulley. Furthermore, to prevent the friction profile from contacting the active pulley, the present invention only provides the active pulley on the left side of the friction profile. To ensure the stability of the active sliding door, the present invention ensures that the right lower surface of the friction profile is in constant contact with at least one driven pulley, thereby coordinating with the left active pulley to ensure the stability of the active sliding door.

[0031] Based on the above embodiment, when assembling the linkage door, the driven pulley 310 is installed on the driven sliding door 30. The driven pulley 310 is then hoisted into the interior of the slide rail 110. The driven sliding door 30 is then hoisted by the driven pulley 310. The friction profile 40 and the active pulley 210 are then installed on the active sliding door 20. The active pulley 210 is then hoisted into the interior of the slide rail 110, with the lower right surface of the friction profile 40 in contact with the upper surface of the driven pulley 130. This allows the active sliding door 20 to be hoisted.

[0032] When the active sliding door 20 moves to the right, the active pulley 210 moves relative to the slide rail 110. At the same time, the friction profile 40 moves to drive the driven pulley 310 to rotate, so that when the driven pulley 310 moves relative to the slide rail 100, it drives the driven sliding door 30 to move, so as to realize the synchronous movement of the active sliding door 20 and the active sliding door 30 and realize linkage.

[0033] See also Figure 4 The active sliding door 20 is provided with a first hoisting profile 50 , and the friction profile 40 is fixedly provided on the first hoisting profile 50 ; the active pulley 210 is rotatably provided on the first hoisting profile 50 on the left side of the friction profile 40 .

[0034] See also Figure 4 A second hoisting profile 300 is provided on the driven sliding door 30 , and the driven pulley 310 is rotatably provided on the second hoisting profile 300 .

[0035] See also Figure 5 and Figure 6 A positioning member 70 is provided on the lower end surface of the active sliding door 20 and the driven sliding door 30; the positioning member 70 of the active sliding door 20 cooperates with the driven sliding door 30 for positioning; the positioning member 70 of the driven sliding door 30 cooperates with the bottom rail 80 for positioning.

[0036] The function of the positioning member 70 is to improve the stability of the active sliding door 20 and the driven sliding door 30 during the movement process.

[0037] See also Figure 5 A mounting profile 60 is provided on the lower end surface of the active sliding door 20 and the driven sliding door 30, and the positioning member 70 is detachably connected to the mounting profile 60.

[0038] See also Figure 5 and Figure 6 The mounting profile 60 is provided with a mounting slot 610, and the mounting profile 60 is provided with a positioning hole 600 that is interconnected with the mounting slot 610;

[0039] The positioning member 70 is provided with a mounting block 700, which is movably inserted into the mounting slot 610. The mounting block 700 is provided with a deformable portion 720, which is provided with a positioning protrusion 730 that is movably inserted into the positioning socket 600. During assembly, the mounting block 700 is inserted into the mounting slot 610 until the positioning protrusion 730 snaps into the positioning socket 600, thereby securing the position. During disassembly, the positioning protrusion 730 is pressed to disengage it from the positioning socket 600, and the mounting block 700 can be withdrawn to remove the positioning member 70.

[0040] See also Figure 5 The positioning member 70 is provided with a limiting groove 710 with an upper end opening, and the bottom rail 80 or the mounting profile 60 of the driven sliding door 30 is provided with a positioning rib 100, and the positioning rib 100 is inserted into the limiting groove 710 from top to bottom.

[0041] During the left and right movement of the active and driven sliding doors 20 and 30, the positioning member 70 moves relative to the positioning rib 100. The positioning rib 100 is inserted into the limiting groove 710 to restrict the forward and backward shaking of the lower ends of the active and driven sliding doors 20 and 30, thereby ensuring the movement stability of the sliding doors.
