[0030] In an embodiment of the track door self-adaptive adjusting device of the present application, please refer to Figures 1 to 8 The track door self-adaptive adjusting device 1 of the present embodiment is used to connect the sliding door and the support rail 10, so that the sliding door can stably slide on the support rail 10 to open and close. Specifically, the track door self-adaptive adjusting device comprises a connecting seat 100, a pulley 200 and a mounting seat 300. The connecting seat 100 has a side plate 110, and a support portion 120 extends horizontally on the bottom side of the side plate 110, and the support portion 120 is provided with a connecting through hole 121. The side surface of the side plate 110 is provided with two pulleys 200, and the two pulleys 200 are distributed on both sides of the support portion 120, and the two pulleys 200 are used to support on the support rail 10. The mounting seat 300 extends a connecting portion 310, and the connecting portion 310 is supported on the top side of the support portion 120, and the connecting portion 310 is provided with a connecting shaft 320, and the connecting shaft 320 passes through the connecting through hole 121, and the connecting shaft 320 and the connecting through hole 121 are provided with a first adjusting gap 122, and the bottom side of the connecting shaft 320 is provided with a limiting portion 321 for limiting on the bottom side of the support portion 120, and the limiting portion 321 and the bottom side of the support portion 120 are provided with a second adjusting gap 322. The top side of the support portion 120 and / or the bottom side of the connecting portion 310 are provided with a circular arc surface, so that the mounting seat 300 can swing left and right, and is limited by the connecting shaft 320 and the limiting portion 321 at the bottom end of the connecting shaft 320, so that the two pulleys 200 can be self-adaptively adjusted within the limiting range of the first adjusting gap 122 and the second adjusting gap 322 relative to the mounting seat 300. The bottom side of the mounting seat 300 is provided with a clamping position 330 for connecting the sliding door.

[0031] Specifically, the track door self-adaptive adjusting device of the embodiment connects the top side of the sliding door to the clamping position 330, so that the sliding door is connected to the mounting seat 300 as a whole, and the pulley 200 is supported on the supporting rail 10. Since the top side of the supporting part 120 and / or the bottom side of the connecting part 310 are provided with a circular arc surface, and under the connection and limiting effect of the connecting shaft 320, the supporting part 120 and the connecting part 310 can be relatively swung and self-adaptively adjusted. When the horizontal of the sliding door exists a degree of inclination or each pulley 200 is not in the same plane due to assembly errors, after the sliding door is installed on the clamping position 330, the connecting part 310 will be subjected to the gravity of the sliding door, and the supporting part 120 will be subjected to the downward pressure of the connecting part 310, which will cause the connecting part 310 to be deflected by a certain angle relative to the supporting part 120, thereby ensuring that the sliding door can eliminate the inclination, and the connecting line between the centers of each pulley 200 is parallel to the supporting rail 10, so that each pulley 200 can be always supported on the supporting rail 10 in close contact with the supporting rail 10, and the force acting on each pulley 200 is relatively balanced and stable, avoiding the problem that some pulleys 200 are subjected to excessive force and are worn due to uneven force. And facilitate the installation of the sliding door, when there is an error in installation, the pulley 200 can also ensure stable operation on the supporting rail 10.

[0032] Preferably, please refer to Figures 5 to 8 , the top side of the supporting part 120 is provided with an upwardly arched circular arc surface 123, and the bottom side of the connecting part 310 is supported on the circular arc surface 123, so that the connecting part 310 and the supporting part 120 are in line contact, thereby enabling the mounting seat 300 to rotate around the connecting shaft 320. Specifically, the bottom side of the connecting part 310 can be a flat surface. In addition, the bottom of the connecting part 310 can also be an outwardly convex circular arc surface, and the top of the supporting part 120 can be a flat surface. In the embodiment, when the clamping position 330 of the mounting seat 300 is misaligned with the two pulleys, after the sliding door is connected to the clamping position 330 of the two sets of mounting seats 300, the position of the mounting seat 300 can be automatically corrected, so that the two sets of mounting seats 300 connected to the sliding door can be kept in the same straight line.

[0033] Still further, please refer to Figure 6 and Figure 7 , the connecting shaft 320 is fixedly connected with the connecting part 310. More preferably, the second adjusting gap 322 is filled with elastic glue 340. In the embodiment, the elastic glue 340 can limit the connecting shaft 320, so that the connecting shaft 320 can be fixed to avoid shaking and other problems, and ensure that noise and other problems do not occur during operation.

[0034] Further, please refer to Figures 5 to 7, the mounting base 300 comprises a connecting plate 301 and a mounting plate 302, the upper end of the connecting plate 301 is bent to form a connecting portion 310. The mounting plate 302 is arranged on the outer side of the connecting plate 301, and the upper end of the mounting plate 301 extends an adjusting support plate 303, which is located on the top side of the connecting portion 310. The adjusting support plate 303 is provided with a threaded hole 304, and an adjusting screw 305 is connected to the threaded hole 304, and the bottom end of the adjusting screw 305 is supported on the top side of the connecting portion 310.

In addition, the support force of the adjusting screw 305 makes the connection between the connecting shaft 302 and the connecting plate 301 more stable. Moreover, it can also avoid the problem of wear caused by the direct contact between the adjusting screw 305 and the connecting portion 310.

[0036] Further, referring to Figure 3 , the bottom side of the mounting plate 302 is bent inwardly to form a bottom plate 308, and the bottom plate 308 is located on the bottom side of the support guide rail 10; the clamping position 330 is arranged on the bottom side of the bottom plate 308. In this embodiment, the center of gravity of the clamping position 330 connected with the sliding door is located on the bottom side of the pulley 200, which effectively avoids the problem of the pulley 200 overturning.

[0037] Further, referring to Figure 8The pulley 200 is provided with an annular groove 210, and the annular groove 210 comprises a groove bottom 211 and an annular sidewall 212. The groove bottom 211 is an inner arc surface. The top surface of the support rail 10 is an outer arc surface, and the diameter of the circle where the groove bottom 211 is located is greater than the diameter of the circle where the top surface of the support rail 10 is located. Therefore, when the pulley 200 is hung on the support rail 10, the highest position of the groove bottom 211 is partially attached to the top surface of the support rail 10, the contact area can be reduced, and the side surface of the annular groove 210 is prevented from contacting the support rail 10, so that the problem of sliding friction of the pulley 200 on the support rail 10 is avoided, and the problem of noise of the pulley 200 in the running process is avoided.

[0038] Further, the two ends of the side plate 110 are bent and formed with a guard plate 111, and the pulley 200 is located between the two guard plates 111. The pulley 200 can be well protected by the guard plate 111, and the problem of being impacted by the pulley is avoided.
