[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0036] like Figures 1 to 13 As shown, this utility model is a linkage sliding door, which can be roughly divided into three parts: frame 1, sliding door 2, and linkage device. The sliding door 2 may include an active door 20 and a passive door 21, while the linkage device further includes an active door pulley group 30 and a passive door pulley group 31.

[0037] The driven door 21 is movably assembled into the frame 1 via the driven door pulley assembly 31, while the active door 20 is movably assembled into the frame 1 via the active door pulley assembly 30. Regarding the positioning and assembly of the sliding door 2 with the frame 1, specifically, the vertical profile 201 of the sliding door 2 has a hollow structure, with an auxiliary fitting 202 embedded at its top. The auxiliary fitting 202 has a right-angle locking position 2020 for the linkage device to be secured, and is also equipped with a locking component 203 for further reinforcement of the linkage device's assembly position on the vertical profile 201. This structure is readily available during production, greatly facilitating later installation without requiring extensive additional assembly modifications, and even saving or eliminating the need for auxiliary installation methods such as glass glue that affect aesthetics or have long waiting times.

[0038] The present embodiment is based on three linkage to illustrate, so the active door 20 has two, and the driven door 21 only one, two active door 20 is set in the front and rear side of the driven door. Among them, the driven door pulley set 31 is symmetrically provided with a set of pulley 310, the set of pulley 310 is connected by setting a belt 311 to move, and the active door pulley set 30 on the active door 20 is connected with the driven door pulley set 31 on the driven door 21 through the connecting piece 4. When the extension can be explained, the connecting piece 4 is provided with internal thread screw hole 40 on one side, the other side is designed into the clamping piece structure 41, the internal thread screw hole 40 is fixed on the active door pulley set 30 through the cooperation with the screw, and the clamping piece structure 41 on one side is engaged with the belt 311 on the driven door pulley set 31. The cooperation with it is that the bottom of the active door 20 and the driven door 21 is designed with the limit guide 200, the limit guide 200 is extended to the inside of the frame 1 to be nested and positioned in, through the setting of the two places, the user can realize linkage when pushing the active door 20, the driven door 21 and the other active door 20.

[0039] Among them, the inner side of the clip structure 41 is designed as a sawtooth structure, which can increase the clamping force and ensure the stability of the linkage, that is, the active door 20 can stably and smoothly drive the driven door 21 and the other driven door 20 to move when moving, because the three are mainly connected by the connecting piece 4 to realize linkage; in addition, the driven door pulley set 31 comprises a hydraulic damping rod, a spring and an adjustable wheel slide 3, so that the utility model not only has a buffering function, but also avoids the problems of linkage failure, slipping and swinging collision based on the design of the linkage device above and the limiting guide 200 below; regarding the pulley set, the driven door pulley set 31 and the active door pulley set 30 are provided with adjustable wheel slides 3, which are different from the existing adjustable wheel slides in that the through holes 314 for the toothed screws 312 to rotate into are arranged on the left and right sides of the adjustable wheel slide 3 instead of the front and back, and the purpose of this design is to hide the active door pulley set 30 and the driven door pulley set 31 into the upper profile 11, because if the through holes 314 are arranged on the front and back of the adjustable wheel slide 3, it means that the screws need to be exposed outside the upper profile 11 to be used by the user to adjust the height with a screwdriver, otherwise the upper profile 11 needs to be disassembled to adjust the height again, so the utility model is arranged on the side to hide the pulley set in the upper profile 11, realize protection, shielding and beauty, and can maintain the function of directly adjusting the height, because the track 110 of the upper profile 11 is not closed, the user can enter the pulley set in the track 110 after pushing the sliding door 2 to reach the pulley set inside, directly insert the through hole 314 of the adjustable wheel slide 3 of the corresponding pulley set and rotate it; in addition, the limiting guide 200 is positioned and welded at the bottom of the active door 20 and the driven door 21, and is extended into the inside of the frame 1 to be nested and positioned inside, specifically embedded in the recessed groove 100 of the lower profile 10, to ensure that the limiting guide 200 realizes the straight and stable movement of the sliding door 2, and can limit the front and back horizontal movement and swinging of the sliding door 2, avoid swinging collision during use, so that the inner cavities of the upper profile 11 and the lower profile 10 do not reserve too much space for the linkage device or the limiting guide 200, which can not only weaken the displacement and change, but also make the profile more simple and slender, realize integration in vision, and make the whole more beautiful.

[0040] Another innovative design of the utility model is the connecting piece 4, which is designed in a U-shaped structure, which is designed to match the structure of the upper profile 11 and connect the active door pulley set 30 and the driven door pulley set 31 for linkage, and the structure design is reasonable and simple, which achieves the research and development purpose, and does not need to change the horizontal span of the profile to link the active door pulley set 30 and the driven door pulley set 31 by opening holes and grooves in the profile during assembly, and the design of the sawtooth structure in the middle makes it have stable and efficient working effect, and one pulley set can be set between the pulley sets, which is not limited to three-linkage sliding doors.

[0041] The utility model discloses user can drive the screw embedded in the auxiliary pipe fitting 202 to go up or drop through the rotation toothed screw 312, thereby drive the door frame with glass door embedding to make the overall height adjustment, and the design can reach more practical and flexible effect compared to the tradition, to satisfy more situations under the installation occasion, and the utility model pulley set hides in the upper profile and is not exposed, realizes protection, shielding and beautiful, can keep the function of direct height adjustment more.
