Technical Field
[0001] This application relates to the field of sliding doors, and more particularly to a sliding door guide rail bracket. Background Technology
[0002] Sliding doors are doors that slide open and close. Initially, sliding doors were only used for bedroom or dressing room wardrobes. However, with technological advancements and the diversification of decoration methods, from traditional panel surfaces to glass, fabric, and rattan, and from sliding doors and folding doors to partition doors, the function and scope of use of sliding doors have continuously expanded. In this context, the application of sliding doors has become more diverse and abundant.
[0003] Most sliding doors currently on the market are equipped with guide rails, and the sliding doors use sliding wheels on the door to cooperate with the guide rails to achieve the purpose of sliding. However, the sliding wheels and sliding doors are assembled together, and there is a gap between the two. If there are hard debris inside the track directly below the sliding door, it may push the sliding door to move upward. At this time, the sliding wheels at the top of the sliding door will move and may separate from the guide rail, causing the sliding door to move intermittently. In severe cases, it may cause the sliding wheels and guide rails to become misaligned, and the sliding door to tip over. Utility Model Content
[0004] To address the issue that if there are hard objects inside the track directly below the sliding door, they may push the sliding door upwards, causing the upper sliding wheels of the sliding door to move and potentially separate from the guide rail, this application provides a sliding door guide rail bracket.
[0005] The sliding door guide rail bracket provided in this application adopts the following technical solution: The device includes a guide rail frame, a movable box movably mounted on the inner side of the guide rail frame, a support block installed inside the movable box, a rotating rod rotatably mounted on the inner side of the support block, a set of opposing threads on the rotating rod, a movable block connected to the rotating rod via the threads, extension rods mounted on both sides of the movable block, an adjusting rod movably connected to the movable block via the extension rods, a connecting shaft mounted on the upper end of the adjusting rod, and an abutment wheel movably connected to the adjusting rod via the connecting shaft.
[0006] By adopting the above technical solution, the adjusting rod moves around the central axis, and the upper end of the adjusting rod gradually moves upward. Through the connecting shaft, it drives the abutment wheel to move upward. The upper part of the abutment wheel contacts the upper inner side of the guide rail frame. At this time, through the reverse force, the moving wheel can be positioned on the moving platform.
[0007] Preferably, there are two moving blocks and two adjusting rods, the two adjusting rods are arranged in a cross configuration, and the intersection of the two adjusting rods is movably connected by a central shaft.
[0008] By adopting the above technical solution, the extension rod can also drive the two adjusting rods to move. At this time, the lower part of the adjusting rod gradually moves inward, the adjusting rod moves around the central axis, and the upper end of the adjusting rod gradually moves upward.
[0009] Preferably, there are two abutting wheels, with the upper parts of the two abutting wheels abutting against the upper inner side of the guide rail frame, and an adjustment handle is installed at one end of the rotating rod.
[0010] By adopting the above technical solution, the rotating rod is rotated by adjusting the handle. When the rotating rod rotates, it will drive two moving blocks to move inward simultaneously through a set of relatively arranged threads.
[0011] Preferably, the movable box has movable slots on both sides, the width of the movable slots is adapted to the diameter of the extension rod, one end of the extension rod is located inside the movable slots, and can move inside the movable slots.
[0012] By adopting the above technical solution, when the moving block moves inward, it can drive the extension rod to move synchronously. At this time, the extension rod moves inside the moving groove, which can ensure the smoothness of the moving block's movement.

[0014] By adopting the above technical solution, when the two moving blocks move inward, they can gradually come into contact with the pushing plate. When moving continuously, the spring contracts, which can prevent the moving blocks from moving out of the maximum stroke of the thread.
[0015] Preferably, one end of the spring is connected to the connecting cylinder, and the other end is connected to the push plate. There are two springs and push plates, which are respectively located at both ends of the connecting cylinder and are arranged opposite to each other.
[0016] By adopting the above technical solution, when it is necessary to move the moving block outward, the force of the spring can facilitate the movement of the moving block.
[0017] Preferably, a movable platform is provided on the lower inner side of the guide rail frame, and movable wheels are installed on both sides of the movable box, with the movable wheels located on the movable platform.
[0018] By adopting the above technical solution, the movable box can be easily moved inside the guide rail frame by means of the movable wheels.
[0019] In summary, this application includes at least one of the following beneficial technical effects: 1. In this application, the adjusting rod moves around the central axis, and the upper end of the adjusting rod gradually moves upward. This drives the abutment wheel to move upward through the connecting shaft. The upper part of the abutment wheel contacts the upper inner side of the guide rail frame. At this time, through the reverse force, the moving wheel can be placed on the moving platform and fit against the moving platform. This can effectively reduce the movement space of the moving wheel, so that the moving wheel is located inside the guide rail frame, thereby improving the overall stability. 2. This application uses an adjustable handle to drive the rotating rod to rotate. When the rotating rod rotates, it drives two moving blocks to move inward simultaneously through a set of opposing threads. When the moving blocks move inward, they can drive the extension rod to move synchronously. At this time, the extension rod moves inside the moving groove, which can ensure the smooth movement of the moving blocks. Attached Figure Description

[0021] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.
[0022] This application discloses a sliding door guide rail bracket, including a guide rail frame 1. A movable platform 2 is provided on the lower inner side of the guide rail frame 1. Movable wheels 4 are installed on both sides of a movable box 3, and the movable wheels 4 are located on the movable platform 2. The movable box 3 is movably installed on the inner side of the guide rail frame 1. A support block 5 is installed inside the movable box 3. A rotating rod 6 is rotatably installed on the inner side of the support block 5. A set of opposing threads 7 are provided on the rotating rod 6. The rotating rod 6 is connected to a movable block 8 through the threads 7. Extension rods 9 are installed on both sides of the movable block 8. The movable block 8 is movably connected to the extension rods 9. An adjusting rod 10 is movably connected, and a connecting shaft 12 is installed at the upper end of the adjusting rod 10. The adjusting rod 10 is movably connected to an abutment wheel 13 through the connecting shaft 12. The extension rod 9 can also drive the two adjusting rods 10 to move. At this time, the lower part of the adjusting rod 10 gradually moves inward, and the adjusting rod 10 moves around the central shaft 11. The upper end of the adjusting rod 10 gradually moves upward, and the abutment wheel 13 moves upward through the connecting shaft 12. The upper part of the abutment wheel 13 contacts the upper inner side of the guide rail frame 1. At this time, through the reverse force, the moving wheel 4 can be positioned on the moving platform 2.
[0023] Please refer to Figure 1 and Figure 2 There are two moving blocks 8 and two adjusting rods 10. The two adjusting rods 10 are arranged in a cross configuration, and the intersection of the two adjusting rods 10 is movably connected by a central shaft 11. There are two abutting wheels 13. The upper part of the two abutting wheels 13 abuts against the upper inner side of the guide rail frame 1. An adjusting handle 15 is installed at one end of the rotating rod 6. Moving grooves 14 are opened on both sides of the moving box 3. The width of the moving groove 14 is adapted to the diameter of the extension rod 9. One end of the extension rod 9 is located inside the moving groove 14 and can move inside the moving groove 14. The rotating rod 6 is driven to rotate by adjusting handle 15. When the rotating rod 6 rotates, it will drive the two moving blocks 8 to move inward simultaneously through a set of relatively arranged threads 7. When the moving blocks 8 move inward, they can drive the extension rod 9 to move synchronously. At this time, the extension rod 9 moves inside the moving groove 14, which can ensure the smooth movement of the moving blocks 8.
[0024] Please refer to Figure 2 A connecting cylinder 16 is installed in the middle of the rotating rod 6. A spring 17 and a push plate 18 are also installed on the outside of the rotating rod 6.

There are two springs 17 and push plates 18, which are located at the two ends of the connecting cylinder 16 and are arranged opposite to each other. When the two moving blocks 8 move inward, they can gradually come into contact with the push plate 18. When moving continuously, the spring 17 contracts, which can prevent the moving blocks 8 from moving out of the maximum stroke of the thread 7. When it is necessary to move the moving blocks 8 outward, the force of the spring 17 can facilitate the movement of the moving blocks 8.
[0025] The implementation principle of a sliding door guide rail bracket in this application embodiment is as follows: During overall installation, the movable box 3 is first installed inside the guide rail frame 1. Then, the adjustment handle 15 is rotated, which drives the rotating rod 6 to rotate. When the rotating rod 6 rotates, it drives two movable blocks 8 to move inward simultaneously through a set of relatively arranged threads 7. When the movable blocks 8 move inward, they can drive the extension rod 9 to move synchronously. At this time, the extension rod 9 moves inside the movable groove 14, which can ensure the smooth movement of the movable blocks 8. The extension rod 9 can also drive two adjustment rods 10 to move. At this time, the lower part of the adjustment rod 10 gradually moves inward, and the adjustment rod 10 moves around the central axis 11. The upper end of the adjustment rod 10 gradually moves upward, and the connecting shaft 12 drives the abutment wheel 13 to move upward. The upper part of the abutment wheel 13 contacts the upper inner side of the guide rail frame 1. At this time, through the reverse force, the movable wheel 4 can be located on the movable platform 2 and fit against the movable platform 2.
[0026] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
