[0023] The present utility model will be further described in detail below with reference to the accompanying drawings.

[0024] As Figure 1 , 2 shown, the ground rail linkage door includes a hanging rail A, a door leaf B and a ground rail C. This embodiment is a three-linkage door with three door leaves, and the figure shows the unfolded state of each door leaf. Lower wheels D are installed at both ends of the bottom of the outer door leaf, drive wheel sets E are installed at both ends of the bottom of the middle door leaf, and the lower wheels D and the drive wheel sets E are installed on the ground rail C through a bottom profile G at the bottom of the door leaf.

The drive belt pulls each door leaf to move relative to each other through the belt clip to achieve the purpose of opening and closing the door.

[0025] As Figure 1 , 2As shown in Figures 3, 4, 5, and 6, the lower wheel D and the transmission wheel set E are both assembled by a pulley frame 1 and a base 2. The pulley frame 1 is internally provided with an adjusting plate 3, the adjusting plate 3 is internally provided with a wheel plate 4, a vertical wheel 5 is installed on the wheel plate 4, both sides of the adjusting plate 3 are provided with inclined grooves 6, both sides of the pulley frame 1 are provided with vertical grooves 7, and a connecting shaft sequentially passes through the vertical grooves 7 and the inclined grooves 6 to connect the adjusting plate 3 and the wheel plate 4 to both sides of the pulley frame 1. An adjusting bolt 8 passes through one end of the pulley frame 1 and is threadedly connected to the adjusting plate 3. The adjusting bolt 8 is arranged along the length direction of the pulley frame 1, and the screw head 9 of the adjusting bolt 8 abuts against the end face of the pulley frame 1. By turning the screw head 9, the adjusting bolt 8 drives the adjusting plate 3 to move along the length direction of the pulley frame 1. At the same time, the connecting shaft drives the wheel plate 4 and the vertical wheel 5 to move along the inclined grooves 6. Due to the limiting effect of the vertical grooves 7, the connecting shaft drives the wheel plate and the vertical wheel to move up and down in the vertical direction, thereby adjusting the height of the vertical wheel.

[0026] When the base 2 and the pulley frame 1 are assembled, the bottom surface of the base 2 and the bottom surface of the pulley frame 1 are located in the same plane 10, and this plane is the assembly surface for installing the profile. Both sides of the base 2 are provided with inserting plates 11, the bottom surface of the base 2 is provided with grooves 12 along both sides of the base 2, the grooves 12 are connected to one end of the base 2, and the bottom surface of the base 2 is provided with two inclined mounting holes 13. Screws can be driven obliquely along the mounting holes 13 to fix the base 2 to the profile. Both sides of one end of the pulley frame 1 are provided with convex plates 14, and both sides of the convex plates 14 are provided with a first card slot 15 and a second card slot 16. The convex plates 14 are correspondingly clamped in the grooves 12, one end of the base 2 is clamped in the first card slot 15, and one end face of the inserting plate 11 of the lower wheel D is provided with a hook plate 17, and the other end face of the inserting plate 11 abuts against the second card slot 16, thereby fixing the base to the pulley frame. The base 2 is provided with an operation hole 21, and a screwdriver can be inserted through the operation hole 21 to the screw head 9 to adjust the adjusting bolt 8.

[0027] The top surface of the base 2 of the transmission wheel set E is provided with a horizontally arranged transmission wheel 19 through a slider 18, a transmission belt is installed on the transmission wheel, the base 2 is provided with a bottom groove 20, the slider 18 is slidably installed in the bottom groove 20, the bottom groove 20 is communicated with the operation hole 21, and the axis of the transmission wheel 19 intersects with the axis of the adjusting bolt 8. The slider 18 is provided with a screw rod 22 in a direction deviating from the axis of the adjusting bolt 8. The screw rod 22 is threadedly connected to the end face of the bottom groove 20, and the screw rod 22 is provided with a limiting groove 23, and the limiting groove 23 is limited by a pin 24 passing through the bottom of the slider 18. A partition plate 25 is provided between the two inserting plates 11 on the bottom surface of the base 2, and a baffle 26 is provided on the end face of the partition plate 25. By turning the screw rod 22, the screw rod 22 drives the slider 18 to slide along the bottom groove 20. At this time, the transmission wheel drives the transmission belt to move, thereby achieving the purpose of adjusting the tightness of the transmission belt. The screw rod is arranged in a direction deviating from the axis of the adjusting bolt, effectively utilizing the width direction of the slider, and overcoming the disadvantages of the overall height increase of the base and the non-compact structure caused by arranging it in the height direction of the slider.

[0028] As Figure 1 , 2 shown in Figures 7 and 8, the upper wheel F has the mounting seat F1 as the base. The two sides of the mounting seat F1 are stepped to form the convex strips F2. One end face of each convex strip F2 is provided with the stop F3, and the other end is provided with the inclined block. The inclined block facilitates the insertion of the profile groove at the entrance. An inclined jack F4 is arranged along the bottom surface of the mounting seat F1 from one side of the stop F3, and the jack F4 is exposed from the bottom surface of the mounting seat F1.

[0029] The top surface of the mounting seat F1 is provided with the adjusting frame F5 and the sliding plate F6. The two sides of the adjusting frame F5 and the two sides of the sliding plate F6 protrude from the top surface of the mounting seat. The protruding part forms the slot F7 with the step of the mounting seat. The adjusting frame F5 is provided with the L-shaped bending plate, and the sliding plate F6 is also provided with the L-shaped bending plate. The adjusting frame F5 and the sliding plate F6 are arranged in sequence along the length direction of the mounting seat 1 from one side of the stop F3. The L-shaped bending plate of the adjusting frame F5 is close to one side of the stop F3. The tail of the adjusting frame F5 corresponds to the L-shaped bending plate of the sliding plate F6. The two ends of the connecting plate F8 are respectively installed with the first pulley F9 and the second pulley F10 on the sliding plate F6. The L-shaped bending plates of the adjusting frame F5 and the sliding plate F6 are connected by the bolt F11. A buffer baffle F12 is fixed by screws on one side of the adjusting frame F5. The buffer baffle is used in cooperation with the buffer hook arranged at the top of the door frame, delaying the closing speed of the door leaf.

[0030] When the upper wheel F is installed on the profile at the top of the door body, the mounting seat F1 is inserted into both sides of the profile groove through the convex strips F2, and the slot F7 is inserted into the rib of the side wall of the profile groove, thus increasing the installation surface between the mounting seat and the profile groove. And the end face of the profile groove is hooked by the stop F3, and then the mounting seat is fixed on the bottom surface of the profile groove through the screw passing through the jack F4, forming four fixing surfaces of the convex strip, the slot, the jack and the hook platform, ensuring the structural firmness of the mounting seat.

[0031] The installation heights of the first pulley F9 and the second pulley F10 are the same and are arranged parallel to the mounting seat F1. The connection line of the first pulley F9 and the second pulley F10 deviates from the length direction of the mounting seat F1. The connecting plate F8 is installed on the first inclined groove F14 of the sliding plate F6 through the first limit post F13, and the connecting plate F8 is installed on the second inclined groove F16 of the sliding plate F6 through the second limit post F15. The sliding plate F6 is installed with the limit pin F18 inserted into the mounting seat F1 through the longitudinal groove F17. Turn the bolt F11 to make the sliding plate F6 move along the limit pin F18. At the same time, the sliding plate F6 pushes the first limit post F13 to move through the first inclined groove F14 and pushes the second limit post F15 to move through the second inclined groove F16, so that the connecting plate F8 rotates relative to the sliding plate F6, thus making the first pulley F9 and the second pulley F10 match the width of the profile groove.
