[0033] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0034] like Figure 1 As shown, it is a structural schematic diagram of the inner sliding door provided by an embodiment of the utility model, and the inner sliding door can be applied to partitions, such as corner partitions in bathrooms, etc. The inner sliding door of this embodiment includes a door panel 10, two vertical frames 20 and two pulley assemblies 30. The door panel 10 is rectangular, the vertical frames 20 are long strips, and the two vertical frames 20 are respectively assembled on the two vertical sides of the door panel 10. In practical applications, the bottom of the vertical frames 20 is flush with the bottom of the door panel 10 or slightly lower than the bottom of the door panel 10. The door panel 10 can be made of glass, so that it can meet the requirements of high humidity environment when used in bathrooms; the vertical frames 20 can be made of rigid materials with greater strength such as stainless steel or aluminum alloy. Specifically, the vertical frames 20 can be made of profiles, which is convenient for production and processing. The two pulley assemblies 30 are respectively fixed at the bottom of the two vertical frames 20. Those skilled in the art can understand that the bottom of the pulley assembly 30 protrudes from the bottom of the vertical frame 20, so that the door panel 10 and the vertical frame 20 can be moved by driving the pulley assembly 30 to rotate.

[0035] Combination Figure 2-Figure 4As shown, each pulley assembly 30 includes a wheel 31, a wheel frame 32 and a mounting frame 33, wherein the wheel 31 is mounted on the wheel frame 32 via a horizontal pivot 35 (i.e., the wheel 31 can rotate around the horizontal pivot 35), and the wheel frame 32 is mounted on the mounting frame 33 via a first vertical pivot (i.e., the wheel frame 32 can rotate around the first vertical pivot), and the mounting frame 33 is fixed to the bottom of the vertical frame 20, and during the rotation of the wheel frame 32 around the first vertical pivot, the wheel 31 is always located outside the vertical projection of the vertical frame 20. Specifically, the wheel frame 32 and the mounting frame 33 can be made of a material with a relatively high hardness (e.g., cast iron, aluminum alloy, stainless steel, etc.), and the wheel 31 can be made of a polymer material, such as plastic, etc., to reduce the noise when it moves in the guide rail 40. The horizontal pivot 35 can be made of screws, rivets or similar structural parts.

[0036] The above-mentioned inward sliding door is provided with a vertical frame 20, and the pulley assembly 30 is assembled to the bottom of the vertical frame 20, so that there is no need to make a notch treatment on the door panel 10, and because the pulley assembly 30 and the door panel 10 are separated, the assembly of the pulley assembly 30 is relatively flexible. For example, the pulley assembly 30 can be assembled in the guide rail 40 first, and then the pulley assembly 30 and the vertical frame 20 (after the door panel 10 and the vertical frame 20 are assembled together) are locked and fixed using the horizontal screw 36, such as Figure 5 shown.

[0037] Combination Figure 2 , Figure 3 As shown, in one embodiment of the present invention, the first vertical pivot includes a bolt portion 341, and the bolt portion 341 includes a threaded section 3411. Accordingly, the wheel frame 32 includes a vertical threaded hole 3221, and the end of the bolt portion 341 has an adjustment groove 3412 (such as a cross groove) adapted to the adjustment tool. The wheel frame 32 is installed on the mounting frame 33 in a manner that the threaded section 3411 of the first vertical pivot is threadedly connected to the vertical threaded hole 3221, and the horizontal pivot 35 of the wheel frame 32 and the wheel piece 31 moves vertically relative to the mounting frame 34 during the rotation of the first vertical pivot.

[0038] Thus, after the pulley assembly 30 is fixed to the bottom of the vertical frame 20, the first vertical pivot can be driven to rotate by an adjustment tool (such as a screwdriver), so that the wheel frame 32 moves upward or downward relative to the mounting frame 33. At the same time, since the mounting frame 33 is fixed to the vertical frame 20, the height of the wheel frame 32 and the wheel piece 31 relative to the door panel 10 will also change, that is, by rotating the first vertical pivot, the height of the door panel 10 can be adjusted. Figure 8 As shown, although the wheel frame 32 will rotate relative to the mounting frame 33 during the movement of the door panel 10, the rotation angle is relatively small, so the height of the door panel 10 is basically not affected during this process.

[0039] In one embodiment of the present invention, the wheel frame 32 includes a main frame plate 321, a fixed arm 322 and two bosses 323, wherein the fixed arm 322 and the bosses 323 are respectively located at two side portions of the main frame plate 321 that are disposed opposite to each other, and a vertical threaded hole 3221 vertically penetrates the fixed arm 322, and the two wheel pieces 31 are respectively mounted on the two bosses 323 through a horizontal pivot 35. The bosses 323 can prevent the edge of the wheel piece 31 from touching the main frame plate 321, and in practical applications, the bosses 323 can also be disposed on the wheel piece 31.

[0040] Correspondingly, the mounting frame 33 includes an upper ear plate 331 and a lower ear plate 332 which are respectively arranged horizontally, and the distance between the upper ear plate 331 and the lower ear plate 332 is greater than the vertical dimension of the fixed arm 322; the upper ear plate 331 has a first mounting hole 3311, and the first mounting hole 3311 vertically penetrates the upper ear plate 331; the lower ear plate 332 has a second mounting hole 3321 coaxial with the first mounting hole 3311, and the second mounting hole 3321 vertically penetrates the lower ear plate 332. The first mounting hole 3311 and the second mounting hole 3321 can be round holes with smooth inner walls, the fixed arm 322 of the wheel frame 32 is inserted between the upper ear plate 331 and the lower ear plate 332, and the bolt portion 341 of the first vertical pivot passes through the first mounting hole 3311, the vertical threaded hole 3221 and the second mounting hole 3321 in sequence to assemble the wheel frame 32 and the mounting frame 33 together.

[0041] Specifically, in the pulley assembly 30, the first vertical pivot also includes a nut portion 342 adapted to the bolt portion 341, the nut portion 342 is arranged below the lower ear plate 332, and the nut portion 342 is threadedly connected to the bottom of the threaded section 3411 of the bolt portion and then welded to the threaded section 3411, that is, after the assembly is completed, the nut portion 342 and the bolt portion 341 can no longer rotate relative to each other, but can only rotate synchronously. In this way, when adjusting the height of the wheel frame 32, it is sufficient to drive the bolt portion 341 and the nut portion 342 to rotate relative to the mounting frame 33. Of course, in practical applications, the first vertical pivot may also adopt other structures.

[0042] like Figure 7 As shown, in one embodiment of the utility model, the vertical frame 20 includes a vertical first mounting groove, the width of the first mounting groove is adapted to the thickness d of the door panel 10, and the door panel 10 is fixed together with the two vertical frames 20 in a manner that the edges on both sides are respectively embedded in the first mounting grooves of the two vertical frames 20.

[0043] Specifically, the width of the first mounting groove on the vertical frame 20 can be 10 mm, and accordingly, the thickness of the door panel 10 can be 8-10 mm. After the door panel 10 is embedded in the first mounting groove, the door panel 10 can be bonded and fixed to the vertical frame 20 by glass glue or the like (when the door panel 10 is a glass door panel).

[0044] In particular, each vertical frame 20 may further include a vertical second mounting groove 22, and the first mounting groove and the second mounting groove 22 are located on adjacent surfaces of the vertical frame 20. Figure 4 , Figure 5 As shown, the bottom of the vertical frame 20 has an escape position that matches the size of the mounting bracket 33, the opening of the escape position and the second mounting groove 22 are located on the same surface of the vertical frame 20, and the second mounting groove 22 extends to the opening of the escape position; the mounting bracket 33 of the pulley assembly 30 is locked and fixed to the bottom wall of the second mounting groove 22 by a horizontal screw 36, and the top of the first vertical pivot is exposed in the second mounting groove 22 or outside the vertical frame 20. That is, after the pulley assembly 30 is assembled to the vertical frame 20, the adjustment groove 3412 of the first vertical pivot is visible, so as to facilitate the rotation adjustment operation of the first vertical pivot.

[0045] like Figure 6 As shown, in one embodiment of the utility model, the inner sliding door further includes a water-blocking rubber strip 24 filled in the second mounting groove 22, a portion of which protrudes out of the second mounting groove and covers the top of the first vertical pivot, thereby ensuring the overall appearance. At the same time, when the inner sliding door is closed, the water-blocking rubber strip 24 contacts other parts (such as a column or a fixing plate, etc.), thereby improving the waterproof performance.

[0046] like Figure 9-12 As shown, the utility model also provides a corner partition, which can be applied to places such as toilets. For example, when the corner partition is applied to toilets, a shower room can be separated by the corner partition. The corner partition of this embodiment includes a first partition 50 located in a first vertical plane, a second partition 60 located in a second vertical plane, and the inward sliding door as described above, wherein the first partition 50 is fixed by a wall column 51 and a column 52, the second partition 60 is fixed by a wall column 61 and a column 62, and the first partition 50 and the second partition 60 are arranged at intervals, and the spacing between the first partition 50 and the second partition 60 is adapted to the width of the inward sliding door. In particular, the first partition 50 and the second partition 60 can be glass plates, respectively, and the width of the first partition 50 is greater than or equal to the width of the door panel 10, and the width of the second partition 60 is less than the width of the door panel 10, so that the inward sliding door cannot be fully opened when it moves in the second vertical plane.

[0047] The bottom of the first vertical plane has a first guide rail 41, and the bottom of the second vertical plane has a second guide rail 42. The lengths of the first guide rail 41 and the second guide rail 42 are respectively greater than or equal to the distance between the two pulley assemblies 30 on the inner sliding door, and the first guide rail 41 is located at the bottom of the first partition 50, and the second guide rail 42 is located in the gap between the first partition 50 and the second partition 60. The inner sliding door is installed between the first partition 50 and the second partition 60 in a manner that the wheel piece 31 of one pulley assembly 30 is embedded in the first guide rail 41, and the wheel piece 31 of the other pulley assembly 30 is embedded in the second guide rail 42. In this way, when the inner sliding door is closed, a relatively closed space is formed inside the first partition 50, the inner sliding door and the second partition 60, such as Fig.11 shown.

[0048] When the inner sliding door is opened, Figure 8 and Fig.10 As shown, the pulley assembly 30 with the wheel piece 31 embedded in the first guide rail 41 slides along the first guide rail 41 (while the wheel frame 32 of the pulley assembly 30 rotates relative to the door panel 10), and the pulley assembly 30 with the wheel piece 31 embedded in the second guide rail 42 slides along the second guide rail 42 (while the wheel frame 32 of the pulley assembly 30 rotates relative to the door panel 10), so that the door panel 10 rotates counterclockwise relative to the first partition plate 50 and the second partition plate 60 until the door panel 10 and the first partition plate 50 are parallel, and the inner sliding door is fully opened. When the inner sliding door is fully opened, because the wheel piece of the pulley assembly 30 is always located outside the vertical projection of the vertical frame 20, there is a gap between the door panel 10 of the inner sliding door and the first partition plate 50, and the pulley assembly 30 located in the second guide rail 42 can still remain in the second guide rail 42.

[0049] The first guide rail 41 and the second guide rail 42 may be made of aluminum alloy. In addition, a stainless steel outer shell 43 may be provided outside the first guide rail 41 and the second guide rail 42 to protect the first guide rail 41 and the second guide rail 42 .

[0050] In one embodiment of the utility model, the angle between the first vertical plane and the second vertical plane is greater than 90° and less than 150°. Within this angle range, the inner sliding door can be opened and closed well.

[0051] In order to improve the stability of the movement of the inner sliding door, in one embodiment of the utility model, the inner sliding door includes two rollers 37, and the two rollers 37 are respectively installed on the top of the two vertical frames 20 through the second vertical pivot 38. Specifically, the second vertical pivot 38 can be composed of a screw and a sleeve. Correspondingly, the corner partition also includes a corner guide rail 70 with an opening downward, a part of the corner guide rail 70 is located above the first guide rail 41 and parallel to the first guide rail 41, and another part of the corner guide rail 70 is located above the second guide rail 42 and parallel to the second guide rail 42, and when the inner sliding door is assembled, the two rollers 37 are respectively embedded in the corner guide rail 70.

[0052] In order to prevent the pulley assembly 30 from falling out of the first guide rail 41 or the second guide rail 42 during the opening or closing process of the inner sliding door, the pulley assembly 30 is Figure 2 and Figure 5 As shown, the inner side surfaces of the first guide rail 41 and the second guide rail 42 (i.e., the side surfaces facing the area enclosed by the first partition plate 50, the door panel 10, and the second partition plate 60) respectively have strip openings arranged in the horizontal direction, that is, the tops of the first guide rail 41 and the second guide rail 42 are closed, and at least a portion of the pulley assembly 30 (e.g., the wheel frame 32) is located in the strip opening, so that under the action of the gravity of the door panel 10, the wheel groove of the wheel piece 31 can be snapped onto the guide rail, and a large lateral pulling force is required to make the wheel piece 31 disengage from the first guide rail 41 or the second guide rail 42.

[0053] In particular, the top of the first guide rail 41 has a partition mounting groove, and the bottom of the first partition 50 is embedded in the partition mounting groove, thereby saving installation space.

[0054] The above is only a preferred specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
