Detailed implementation mode
[0041] The technical features of the present utility model will be further described in detail below in conjunction with the accompanying drawings so that those skilled in the art can understand.
[0042] A concealed track type sliding door includes a sliding door 2 placed in a wall 1 and a first track 4 fixed to the top inside the wall 1. A second track 5 is slidably connected to the first track 4, and a third track 6 capable of driving the second track 5 to move together is slidably connected to the second track 5. The third track 6 is fixed to the top of the sliding door 2. A fourth track 7 is fixed to the bottom inside the wall 1. A fifth track 8 is slidably connected to the fourth track 7, and a sixth track 9 capable of driving the fifth track 8 to move together is slidably connected to the fifth track 8. The sixth track 9 is fixed to the bottom of the sliding door 2.
[0043] The first track 4 is fixed to a profile, and the profile is fixed to the top of the wall 1 by a plurality of screws 10. The first track 4 and the fourth track 7 are fixed inside the wall 1 and are not visible to the naked eye. After the door is closed, part of the second track 5 and the fifth track 8 slide out of the wall 1, but are placed at the top or bottom of the sliding door 2 and do not contact the ground, so they are not visible to the naked eye either. The structure is simple and the appearance is beautiful.
[0044] Specifically, a first fixing block 11 is provided on the second track 5, and a first pushing block 12 capable of pushing the first fixing block 11 and thus pushing the second track 5 in the closing direction is provided on the third track 6. After the sliding door 2 is completely closed, the length of the second track 5 extending out of the wall 1 accounts for about one-third to one-half of the total length of the second track 5. The third track 6 can move completely outside the wall 1 or leave part inside the wall 1. Preferably, part of the third track 6 remains inside the wall 1 after the sliding door 2 is completely closed. In this way, the structure is more reliable and stable, and the service life can be greatly extended.
[0045] On both sides of the second track 5, there are first fixing blocks 11. A groove is formed on the third track 6, and the first fixing blocks 11 are installed in the groove through Jimi screws. On both sides of the third track 6, there are also first pushing blocks 12. A groove is formed on the second track 5, and the first pushing blocks 12 are installed in the groove through Jimi screws. The first pushing block 12 is located above the first fixing block 11. During movement, the lower part of the first pushing block 12 impacts the upper part of the first fixing block 11. This design ensures that there is no interference during the movement process.
[0046] The second track 5 is installed in two parts, front and back. At the right end of the second track 5, there is a second fixing block 13 flush with the end. On the third track 6, there is a second pushing block 14 that can push the second fixing block 13 and thus push the second track 5 in the door-opening direction. The second fixing block 13 is installed in the concave cavity of the second track 5 through Jimi screws without the need for additional grooving. The second pushing block 14 is also provided at the end of the third track 6 and is installed in the concave cavity of the second track 5 through Jimi screws without the need for additional grooving. Moreover, at the right ends of the front and back parts of the second track 5, there are second fixing blocks 13, and on both sides of the third track 6, there are corresponding second pushing blocks 14.
[0047] On the second track 5, there is a first limit post 15. On the first track 4, there is a first limit block 16 that blocks the first limit post 15 to prevent the second track 5 from continuing to move in the door-closing direction after the door is closed. On the third track 6, there is a second limit post 17. On the first track 4, there is a second limit block 18 that blocks the second limit post 17 to prevent the third track 6 from continuing to move in the door-closing direction after the door is closed. The first limit post 15 and the second limit post 17 are both dowel pins, and the first limit block 16 and the second limit block 18 are both fixed to the first track 4 through Jimi screws, as Figure 5 and Figure 6 shown.
[0048] Linear bearings 19 are provided between the first track 4 and the second track 5, between the second track 5 and the third track 6, between the fourth track 7 and the fifth track 8, and between the fifth track 8 and the sixth track 9, enabling relative sliding between the tracks. For example, the second track 5 can slide on the first track 4, and the third track 6 can slide relative to the second track 5, reducing friction. The linear bearing 19 includes a gasket and a plurality of balls placed on the gasket.
[0049] Additionally, a fixed seat 20 can be provided at the left end of the first track 4. A lead screw transmission mechanism 3 is installed on the fixed seat 20, including a motor 301, a lead screw 302 driven by the motor to rotate, and a nut 303 sleeved on the lead screw 302. The nut 303 is fixed on the third track 6 and is used to drive the third track 6 to move left and right to open and close the door. In this way, automatic opening and closing of the door can be achieved.
[0050] A third fixed block 21 flush with the end is provided at the right end of the fifth track 8. A third pushing block 22 that pushes the third fixed block 21 and then pushes the fifth track 8 in the door-opening direction is provided at the end of the sixth track 9. The third pushing block 22 is also a decorative cover. The third fixed block 21 is installed in the concave cavity of the fifth track 8 through a Kimi screw and does not require additional slotting.
[0051] A fourth fixed block 23 is provided on the fifth track 8, and a fourth pushing block 24 that pushes the fourth fixed block 23 and then pushes the fifth track 8 in the door-closing direction is provided on the sixth track 9, as Figure 13 and Figure 15 shown. Fourth fixed blocks 23 are provided on both sides of the fifth track 8. Slots are opened on the fifth track 8, and the fourth fixed blocks 23 are installed in the slots through Kimi screws. Fourth pushing blocks 24 are provided on both sides of the sixth track 9. Slots are opened on the sixth track 9, and the fourth pushing blocks 24 are installed in the slots through Kimi screws. During movement, the inner side of the fourth pushing block 24 impacts the outer side of the fourth fixed block 23. This installation design is simple in structure and ensures that no interference will occur during the movement process.
[0052] A third limit post 25 is provided on the sixth track 9, and a third limit block 26 that blocks the third limit post 25 to prevent the sixth track 9 from continuing to move in the door-closing direction after the door is closed is provided on the fourth track 7.
[0053] A fourth limit post 27 is provided on the fifth track 8. A fourth limit block 28 that blocks the fourth limit post 27 to prevent the fifth track 8 from continuing to move in the door-opening direction after the door is opened is provided on the fourth track 7. A fifth limit block 29 that blocks the fourth limit post 27 to prevent the fifth track 8 from continuing to move in the door-closing direction after the door is closed is provided on the fourth track 7. If it continues to move, it may damage the track and the sliding door. Both the third limit post 25 and the fourth limit post 27 are pins, and the third limit block 26, the fourth limit block 28, and the fifth limit block 29 are all fixed on the fourth track 7 through Kimi screws.
[0054] The embodiments described in the present utility model are only descriptions of the preferred embodiments of the present utility model, and do not limit the inventive concept and scope of the utility model. Without departing from the design concept of the present utility model, various modifications and improvements made by those skilled in the art to the technical solutions of the present utility model shall fall within the protection scope of the present utility model.
