[0022] In this utility model, "first" and "second" do not represent a specific quantity or order, but are merely used to distinguish names.

[0023] like Figure 1 , Figure 2 As shown, this utility model provides a concealed track sliding door and window, including a door leaf 1, a door frame 2, and a lower track frame 3. The door leaf 1 is slidably installed within the door frame 2. Specifically, the door leaf 1 includes a first sliding door leaf 10 and a second sliding door leaf 11, both of which are slidably installed within the door frame 2, and are staggered relative to each other. The sliding door is opened or closed by sliding the first sliding door leaf 10 and / or the second sliding door leaf 11 left or right.

[0024] like Figure 1 , Figure 2 , Figure 3 as well as Figure 5 As shown, the concealed track sliding door and window also includes a pulley load-bearing component 4 and a load-bearing pulley assembly 5. A groove 6 is provided at the top of the lower track frame 3. The upper end of the pulley load-bearing component 4 passes through the groove 6 and is fixedly connected to the bottom of the door leaf 1. The pulley load-bearing component 4 is movably connected to the groove 6 and the lower end of the pulley load-bearing component 4 is located in the inner cavity of the lower track frame 3. The load-bearing pulley assembly 5 is fixedly installed at the lower end of the pulley load-bearing component 4 and is located in the inner cavity of the lower track frame 3.

[0025] Specifically, the lower rail frame 3 is installed on the ground to conceal the pulley support 4 and the load-bearing pulley assembly 5. The load-bearing pulley assembly 5 includes at least two components to ensure smooth and easy movement of the sliding door leaf 1. The concealed track sliding door and window also includes a leaf frame 15, and the upper end of the pulley support 4 is fixedly connected to the bottom of the door leaf 1 through the leaf frame 15.

[0026] As a preferred technical solution, such as Figure 4As shown, the load-bearing pulley assembly 5 includes a connecting plate 51 and pulleys 50. The connecting plate 51 is fixedly installed on the pulley load-bearing component 4. The connecting plate 51 has a slot 52, and the pulley 50 is rotatably installed in the slot 52. Multiple pulleys 50 are symmetrically distributed on both sides of the pulley load-bearing component 4.

[0027] The purpose of providing the connecting plate 51 and the slot 52 within it is to facilitate the installation and replacement of the pulley 50. Simultaneously, the pulley 50's rotatable installation within the slot 52 ensures smooth rolling, improving the stability of the door panel 1 during translation and reducing noise during the pushing and pulling process.

[0028] Furthermore, to prevent the door leaf 1 from wobbling during the translation process, the size of the slide groove 6 is matched with that of the pulley support member 4. Specifically, the pulley support member 4 can be configured as an I-shaped or H-shaped structure, and the thickness of the web plate or waist plate is equal to or slightly less than the width of the slide groove 6, so that the pulley support member 4 can be slidably connected to the slide groove 6.

[0029] The concealed track sliding door and window, by setting a lower track frame 3, places the lower end of the pulley load-bearing component 4 and the load-bearing pulley assembly 5 in the inner cavity of the lower track frame 3, which can hide the track and avoid the track being exposed and affecting the aesthetic performance. It solves the problem of existing flat track sliding doors having the track exposed on the ground, affecting the aesthetic performance, and has good practicality.

[0030] In addition, by concealing the track, mud and dust can be prevented from entering the track and affecting the smooth sliding of the sliding door and damaging the pulley components. It can also prevent tripping caused by uneven track height.

[0031] In one embodiment of this utility model, such as Figure 3 , Figure 4 as well as Figure 6 As shown, the concealed track sliding door and window also includes a dustproof steel strip 13 and a dustproof steel strip guide rail 14. The dustproof steel strip guide rail 14 is fixedly installed on the pulley load-bearing component 4 and located between the pulley load-bearing component 4 and the door leaf 1. The dustproof steel strip 13 is arranged along the length of the slide groove 6 and its two ends are fixedly connected to the door frame 2 through steel strip fixing components 18. The dustproof steel strip 13 covers the slide groove 6 and is located between the dustproof steel strip guide rail 14 and the door leaf 1. The dustproof steel strip 13 and the dustproof steel strip guide rail 14 can move relative to each other. The steel strip fixing component 18 is fixedly connected to the door frame 2 through a steel plate 19.

[0032] Specifically, both ends of the dustproof steel strip 13 are fixed to the door frame 2 by steel strip fasteners 18, and at least part of the dustproof steel strip 13 covers the dustproof steel strip guide rail 14. As the door leaf and the dustproof steel strip guide rail 14 move, the dustproof steel strip 13 and the dustproof steel strip guide rail 14 move relative to each other. One side of the dustproof steel strip 13 is lifted by the dustproof steel strip guide rail 14 and covers the dustproof steel strip guide rail 14, while the other side of the dustproof steel strip 13 detaches from the dustproof steel strip guide rail 14, falls down under its own weight, and covers the slide groove 16.

[0033] When the door leaf 1 is pushed, the dustproof steel strip 13 and the dustproof steel strip guide rail 14 move relative to each other. The dustproof steel strip 13 located on both sides of the dustproof steel strip guide rail 14 will cover the slide groove 6 under its own gravity, completely covering the slide groove 6.

[0034] Preferably, magnetic strips 17 can be provided on both sides of the slide groove 6 along its length. The magnetic attraction between the magnetic strips 17 and the dustproof steel strip 13 can attract and cover the dustproof steel strip 13 onto the slide groove 6, preventing the dustproof steel strip 13 from shifting off the slide groove 6 and improving the overall aesthetics.

[0035] A decorative cover 16 is snapped onto the top of the lower track frame 3. Specifically, the decorative cover 16 is located on both sides of the slide rail 6 and comprises multiple pieces. The surface of the multiple decorative covers 16 is flush with the surface of the dustproof steel strip 13 covering the slide rail 6. In this way, the overall aesthetic performance of the flat track sliding door can be further improved by using the decorative cover 16.

[0036] like Figure 3 As shown, in one embodiment of the present invention, the concealed track sliding door and window further includes a first dustproof strip 7, and the upper end of the pulley load-bearing component 4 is provided with a first slot 8, and the first dustproof strip 7 is engaged with the first slot 8.

[0037] By installing the first dustproof strip 7, the sealing performance and sound insulation performance of the concealed track sliding door and window can be improved.

[0038] Preferably, the first dustproof strip 7 is located between the top of the fan frame 15 and the lower rail frame 3, and there are two first dustproof strips 7, which are symmetrically distributed on both sides of the pulley support member 4.

[0039] Thus, the first dustproof strip 7 not only prevents dust from falling into the slide groove 6 or even the inner cavity of the lower track frame 3, but also covers the pulley load-bearing part 4 located between the bottom of the fan frame 15 and the top of the lower track frame 3, achieving more comprehensive track concealment and further improving the aesthetic performance of the flat track sliding door.

[0040] like Figure 2As shown, in one embodiment of the present invention, the concealed track sliding door and window further includes a second dustproof strip 9. The second dustproof strip 9 is fixedly installed at the bottom of the sash frame 15. The second dustproof strip 9 is located between the sash frame 15 and the lower track frame 3 and is located on one side of the first dustproof strip 7.

[0041] The second dustproof strip 9 not only enhances the sealing and sound insulation performance of the concealed track sliding door and window, but also cleans the top surface of the lower track frame 3, preventing dust accumulation.

[0042] Preferably, such as Figure 3 as well as Figure 6 As shown, the concealed track sliding door and window also includes a stainless steel track strip 12, which is fixedly installed in the inner cavity of the lower rail frame 3. The length direction of the stainless steel track strip 12 is parallel to the length direction of the lower rail frame 3, and the bottom of the load-bearing pulley assembly 5 is slidably connected to the stainless steel track strip 12.

[0043] The stainless steel track 12 comprises two parallel tracks that slidably connect with the concave surface of the pulley 50 to ensure smooth and stable sliding of the door leaf 1. That is, when the pulley 50 is rotatably installed within the slot 52, at least part of the bottom of the pulley 50 protrudes from the bottom of the connector to ensure that the concave surface of the pulley 50 contacts and slidably connects with the stainless steel track 12. Furthermore, the stainless steel track 12 is also concealed within the inner cavity of the lower track frame 3, enhancing the overall aesthetics of the flat-track sliding door.

[0044] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0045] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
