Description

Technical Field

[0001] This utility model relates to the technical field of sliding door track structure, specifically a noise-reducing detachable furniture sliding door track structure. Background Technology

[0002] Sliding doors and windows are widely used due to their advantages of not occupying indoor space, flexible opening, increasing indoor lighting, and improving the overall appearance of buildings. Sliding doors and windows achieve sliding opening and closing through the sliding door track structure. The sliding door track structure usually consists of a fixed main track, a movable secondary track, and a shock-absorbing mechanism. The fixed main track provides horizontal guidance for the door leaf and bears the main load. The movable secondary track works with the main track to achieve smooth sliding. The shock-absorbing mechanism can buffer the movement of the door leaf and reduce the impact noise when closing the door.

[0003] Existing furniture sliding door track structures use welding or cement masonry to fix the main track to the wall or door / window frame, and multiple connecting bolts to fix the sliding door or window and the upper and lower movable auxiliary tracks. If the sliding door track structure needs to be disassembled and repaired, the main track, the movable auxiliary tracks, and the sliding door together must be removed from the wall before the movable auxiliary tracks can slide out from the main track, and then the sliding door track structure can be repaired. This disassembly and assembly operation is cumbersome and difficult. Therefore, to address the above problems, a noise-reducing detachable furniture sliding door track structure is proposed.

[0017] Please see Figure 1-12 This utility model provides a technical solution: A noise-reducing, detachable sliding door rail structure includes a fixed main rail assembly 1 and a movable secondary rail assembly 2. The fixed main rail assembly 1 includes a main rail body 11, with first limiting blocks 12 fixedly connected to both the left and right ends of the main rail body 11. First rubber blocks 13 are fixedly connected to the opposing sides of the two first limiting blocks 12. A detachable bending plate 14 is provided in a groove on the front side of the main rail body 11. Bolt connecting plates 15, which are bolted to the main rail body 11, are fixedly connected to both the left and right ends of the front side of the detachable bending plate 14. A pair of movable secondary rail assemblies 2 are provided between the two first rubber blocks 13. The movable secondary rail assembly 2 includes... The system includes a secondary rail body 21 located on the upper side of the main rail body 11. A mounting plate 22 is fixedly connected to the rearmost part of the upper surface of the secondary rail body 21. A plug rod 23 for inserting a door leaf is fixedly connected to the upper end of the secondary rail body 21. A connecting strip 24 is fixedly connected to the lower side of the secondary rail body 21. A magnet 25 fixedly connected to the secondary rail body 21 is fixedly connected to the opposing sides of the two connecting strips 24. A limiting plate 26 located inside the main rail body 11 is fixedly connected to the lower end of the connecting strip 24. A limiting strip 27 is fixedly connected to the lower side of the limiting plate 26. A rotating wheel 28 is rotatably connected to the circular groove of the limiting strip 27.

[0018] A pair of second limiting blocks 16 are fixedly connected to the middle of the rear side of the detachable bending plate 14. Each of the two second limiting blocks 16 has a second rubber block 17 on its opposite side. Both the second limiting blocks 16 and the second rubber blocks 17 are fitted against the inner wall of the main rail body 11. A compression spring 18 is fixedly connected to the circular groove of each of the second rubber blocks 17. The end of the compression spring 18 away from the second rubber block 17 is fixedly connected to the second limiting block 16. The second rubber blocks 17, in conjunction with the compression springs 18, can buffer the door leaf and prevent it from impacting. The length of the secondary rail body 21 is the same as the main rail body 11. The length of the main track body 11 is one-quarter of the length. The lengths of the secondary track body 21 and the mounting plate 22 are equal. The lengths of the connecting strip 24, the limiting plate 26, and the limiting strip 27 are all equal. The left and right sides of the secondary track body 21 protrude beyond the connecting strip 24. The opposing sides of the two magnets 25 are aligned with the opposing sides of the two secondary track bodies 21. The length of the detachable bending plate 14 is greater than the length of the limiting plate 26 but less than the length of the secondary track body 21. After the detachable bending plate 14 is removed, the door leaf and the movable secondary track assembly 2 can be removed from the main track body 11. The shape of the magnets 25 is the same as that of the second limiting plate 26. The upper grooves of block 16 and the second rubber block 17 are aligned. The length of magnet 25 in the left-right direction is equal to the sum of the lengths of the second limiting block 16 and the second rubber block 17 in the left-right direction. The two magnets 25 attract each other, which can stabilize the door leaf and prevent the compression spring 18 from repeatedly extending and retracting. The main rail body 11 is a "C" shaped track, and the secondary rail body 21 and the limiting plate 26 are both "U" shaped tracks. The lower side of the secondary rail body 21 is in contact with the upper side of the main rail body 11, and the upper side of the limiting plate 26 is in contact with the upper inner wall of the main rail body 11. Both the front and rear sides of the 26 are in contact with the inner wall of the main rail body 11. Noise reduction can be achieved through the cooperation of the secondary rail body 21, the limiting plate 26 and the rotating wheel 28. The lower end face of the limiting strip 27 has a certain gap with the lower inner wall of the main rail body 11. The lower end of the rotating wheel 28 is in contact with the lower inner wall of the main rail body 11. The upper end of the rotating wheel 28 has a certain gap with the lower side of the limiting plate 26. Both the front and rear ends of the rotating wheel 28 have a certain gap with the inner wall of the main rail body 11. The rotating wheel 28 will not rub against the inner walls of the front and rear sides of the main rail body 11 during rotation.

[0019] Workflow: Before use, install the main rail body 11 in a suitable position and bolt the mounting plate 22 to the door leaf. The device can then be used normally. All of the above are existing technologies. When using the device, the operator can pull the door leaf. The force on the door leaf is transmitted through the connecting bolts and the plug rod 23, causing the mounting plate 22 and the secondary rail body 21 to slide left and right. This, in turn, causes the limiting plate 26 and the limiting strip 27 to move synchronously through the connecting strip 24. The secondary rail body 21 and the limiting plate 26 ensure that the limiting strip 27 and the rotating wheel 28 are stably located inside the main rail body 11. Since the rotating wheel 28 can rotate inside the main rail body 11, and the secondary rail... The contact area between the main body 21, the limiting plate 26, and the main rail body 11 is small, resulting in less noise during the movement of the secondary rail body 21. The secondary rail body 21, mounting plate 22, limiting plate 26, and limiting strip 27 are made of high-strength, low-deformation magnesium-aluminum alloy, while the rotating wheel 28 is made of silent nylon. Noise reduction is achieved through the secondary rail body 21, limiting plate 26, and rotating wheel 28, resulting in almost silent push-pull operation. The first rubber block 13, fixed by the first limiting block 12, prevents the secondary rail body 21 from dislodging, and the compression spring 18, fixed by the second limiting block 16, allows the second rubber block 17 to move within the main rail body. The second rubber block 17 moves left and right within 11. When the two doors are closed, the second rubber block 17 is subjected to the force of the limiting plate 26 and the limiting strip 27, causing the compression spring 18 to compress. The second rubber block 17, in conjunction with the compression spring 18, can buffer the door panels and prevent them from colliding. The magnets 25, which are close to each other, can attract each other. The magnets 25 can both ensure the door panels close stably and prevent the compression spring 18 from repeatedly extending and contracting. When the door panels need to be disassembled, the worker only needs to open the two doors and then remove the detachable bending plate 14 and the bolt connecting plate 15, so that the second limiting block 16, the second rubber block 17, and the compression spring 18 move together. The detachable bending plate 14 is removed, and the door leaf is slid to the middle position of the main rail body 11, so that the door leaf and the movable sub-rail assembly 2 can be removed from the main rail body 11. The device can reduce noise through the first rubber block 13, the second rubber block 17, and the compression spring 18. The second limiting block 16, the second rubber block 17, and the compression spring 18 can be removed from the main rail body 11 through the detachable bending plate 14 and the bolt connection plate 15, so that the front groove of the main rail body 11 is exposed, and the door leaf and the movable sub-rail assembly 2 can be quickly removed. The device can be easily and quickly disassembled and reinstalled, so that the device has high maintenance efficiency.
