Description

Technical Field

[0001] The utility model belongs to the field of linkage doors, and particularly relates to a lower wheel and a transmission wheel that slide along a ground rail. Background Art

[0002] Lower wheels and transmission wheels are usually installed at the bottom of a linkage door. The pulley part of the lower wheel is a vertical wheel that slides along the ground rail, while the pulley part of the transmission wheel is a horizontal wheel that slides along the side wall of the profile at the bottom of the door body. Since the functions of the vertical wheel and the horizontal wheel are the same, both can make the sliding of the sliding door labor-saving. If the vertical wheel of the lower wheel and the horizontal wheel of the transmission wheel can be unified, and the pushing and pulling transmission function of the transmission wheel is also ensured, the production cost will be greatly reduced. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a pulley that can be common to the lower wheel and the transmission wheel.

[0004] A ground rail slider includes a pulley frame and a base. The bottom surface of the base and the bottom surface of the pulley frame are in the same plane. One end of the pulley frame is provided with a card slot for clamping the base. The bottom surface of the base is provided with an inclined mounting hole. The two sides of the base are provided with insertion plates, and a vertical wheel is installed on the pulley frame.

[0005] The bottom surface of the base is provided with grooves along both sides of the base. The grooves are connected to one end of the base. Both sides of one end of the pulley frame are provided with convex plates. The two sides of the convex plates are provided with a first card slot and a second card slot. The convex plates are correspondingly clamped in the grooves. One end of the base is clamped in the first card slot, and one end of the insertion plate is placed in the second card slot.

[0006] One end face of the insertion plate is provided with a hook plate, and the other end face of the insertion plate abuts against the second card slot.

[0007] One end of the pulley frame is installed with an adjusting bolt for lifting and adjusting the vertical wheel. The base is provided with an operation hole for operating the adjusting bolt.

[0008] The top surface of the base is installed with a horizontally arranged transmission wheel through a slider. The base is provided with a bottom groove. The slider is slidably installed in the bottom groove. The bottom groove is communicated with the operation hole. The axis of the transmission wheel intersects with the axis of the adjusting bolt.

[0009] The slider is installed with a screw rod in a direction deviating from the axis of the adjusting bolt. The screw rod is threadedly connected to the end face of the bottom groove. The screw rod is provided with a limiting groove, and the limiting groove is limited by a pin passing through the bottom of the slider.

[0010] A partition plate is provided between the two insertion plates on the bottom surface of the base. The end face of the partition plate is provided with a baffle plate.

[0016] The present utility model will be further described in detail below with reference to the accompanying drawings.

[0017] As shown in Figure 1 , 2 , 3, and 4, the ground rail pulley is assembled by a pulley frame 1 and a base 2. An adjusting plate 3 is disposed inside the pulley frame 1, a wheel plate 4 is disposed inside the adjusting plate 3, a vertical wheel 5 is installed on the wheel plate 4, inclined slots 6 are provided on both sides of the adjusting plate 3, vertical slots 7 are provided on both sides of the pulley frame 1, and the adjusting plate 3 and the wheel plate 4 are connected to both sides of the pulley frame 1 by sequentially passing a connecting shaft through the vertical slots 7 and the inclined slots 6. 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 disposed 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, and at the same time, the connecting shaft drives the wheel plate 4 and the vertical wheel 5 to move along the inclined slots 6. Due to the limiting effect of the vertical slots 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.

[0018] When the base 2 is assembled with the pulley frame 1, the bottom surface of the base 2 and the bottom surface of the pulley frame 1 are located in the same plane 10, which is the assembly surface for profile installation. Insertion plates 11 are provided on both sides of the base 2, and grooves 12 are provided along both sides of the bottom surface of the base 2. The grooves 12 are connected to one end of the base 2. Two inclined mounting holes 13 are provided on the bottom surface of the base 2. Screws can be driven obliquely along the mounting holes 13 to fix the base 2 to the profile. Convex plates 14 are provided on both sides at one end of the pulley frame 1. First card slots 15 and second card slots 16 are provided on both sides of the convex plates 14. The convex plates 14 are correspondingly clamped in the grooves 12, and one end of the base 2 is clamped in the first card slot 15. When used as a lower pulley, a hook plate 17 is provided on one end face of the insertion plate 11, and the other end face of the insertion plate 11 abuts against the second card slot 16, thereby fixing the base to the pulley frame. An operation hole 21 is provided on the base 2. A screwdriver can be inserted through the operation hole 21 to the screw head 9 to adjust the adjusting bolt 8.

[0019] When used as a driving pulley, a horizontally arranged driving pulley 19 is installed on the top surface of the base 2 through a slider 18. A bottom groove 20 is provided on the base 2. The slider 18 is slidably installed in the bottom groove 20. The bottom groove 20 communicates with the operation hole 21. The axis of the driving pulley 19 intersects with the axis of the adjusting bolt 8. A screw rod 22 is installed on the slider 18 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. 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 insertion plates 11 on the bottom surface of the base 2. 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 driving pulley drives the transmission belt to move, so as to achieve 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 being arranged in the height direction of the slider.
