[0026] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0027] like Figures 1 to 4 As shown, the utility model is an adjustable limit structure for a hanging rail sliding door. This adjustable limit structure provides a simple solution, allowing users to easily adjust the limit position of the door panel, optimize the sliding performance of the door panel along the guide rail, and ensure smoothness and safety during use. This structural innovation not only improves the stability of the door panel, but also enhances the user's operating experience.

[0028] The adjustable limit structure includes a guide rail 1 fixed on a wall or door frame, and a movable door panel 2 that can slide left and right along the guide rail 1. The movable door panel 2 is rotatably connected to a roller 3 located above the guide rail 1 and cooperating with the guide rail 1. The roller 3 cooperates with the guide rail 1 to ensure the stability and smoothness of the door panel when sliding. A limit groove 11 opening downward is designed at the lower part of the guide rail 1. The movable door panel 2 is also provided with a limit hook 4 located below the guide rail 1. The limit hook 4 extends from the movable door panel 2 and is inserted upward into the limit groove 11. The cleverness of this design lies in that it can both guide and limit the door panel 2, effectively preventing the door panel 2 from swinging or derailing when sliding, and ensuring the safety and reliability of the sliding door.

[0029] More importantly, the innovation of the utility model lies in the realization of the fine-tuning structure. In daily use, the limit position of the door panel may need to be adjusted due to various reasons, such as uneven floor or wear caused by long-term use. At this time, the user can adjust the height of the limit hook 4 through simple manual operation. This structure allows the limit hook 4 to fine-tune its position in the vertical direction, thereby providing more flexibility. More specifically, a fine-tuning structure for fine-tuning the upper and lower positions of the limit hook 4 (the upper and lower positions of the limit hook 4 determine the spacing between the limit hook 4 and the limit groove 11) is provided between the limit hook 4 and the movable door panel 2, and the fine-tuning structure includes a base 5 installed on the door panel, the limit hook 4 is slidably connected to the base 5 along the up and down direction, and a first fastener 6 is provided between the limit hook 4 and the base 5 to fix the two.

[0030] When the height of the limit hook 4 needs to be adjusted, the user can achieve fine adjustment by rotating the first fastener 6. The rotation of the first fastener 6 will lock or release the limit hook 4. After releasing the limit hook 4, the limit hook 4 can be manually slid in the vertical direction.

[0031] The design of this fine-tuning structure is not only practical but also convenient to adjust and has a relatively large adjustment range. It allows the user to adjust the position of the limit hook 4 very accurately according to the needs, whether it is to adapt to floors of different heights or to adapt to the door position that may change over time, it can be easily achieved. The introduction of this structure greatly improves the adaptability and convenience of the hanging rail sliding door in use.

[0032] Furthermore, the base 5 is provided with a mounting hole 51, and the limit hook 4 is provided with a connecting plate 41 that can be inserted into the mounting hole 51 from bottom to top, and the connecting plate 41 can slide up and down in the mounting hole 51, so as to achieve height adjustment. In order to further fix and adjust the position of the connecting plate 41 in the mounting hole 51, the base 5 is also provided with a threaded through hole 52 leading to the mounting hole 51. The first fastener 6 is a top screw or a screw that fits in the threaded through hole 52, and it fits in the threaded through hole 52 to achieve the function of fine-tuning the position of the limit hook 4.

[0033] The cleverness of this design is that the user can fine-tune the vertical position of the limit hook 4 through a simple rotation action. When the first fastener 6 is screwed out of the threaded through hole 52, the connecting plate 41 is unlocked, and after unlocking, the user can manually adjust the upper and lower positions of the limit hook 4. After the position is adjusted to the right position, the user screws the first fastener 6 in again, and its upper end can extend into the interior of the mounting hole 51 and press against the connecting plate 41, thereby locking the limit hook 4. This structure makes the height adjustment of the limit hook 4 convenient, accurate and firm.

[0034] The practicality of this structure lies in its convenient and quick adjustment method, so that users do not need to disassemble the door panel or use complicated tools in daily use. Users only need to simply rotate the first fastener 6 to finely adjust the limit position of the door panel as needed. This design not only provides users with a better use experience, but also reduces the risk of wear or discomfort of the door body during long-term use, ensuring that the sliding performance of the door panel is stable and reliable in the long term.

[0035] More specifically, the threaded through hole 52 is tilted, and the front end of the threaded through hole 52 opens downward and is located on the bottom surface of the base 5, and the rear end of the threaded through hole 52 opens upward and is connected to the mounting hole 51. This design significantly enhances the operability and maintenance convenience of the entire device. The tilted threaded through hole 52 not only complies with the ergonomic principle and reduces the inconvenience during installation and debugging, but also makes it easy to use tools for adjustment even in a small space or at an inconvenient angle.

[0036] Specifically, the front opening of the threaded through hole 52 is designed to face downward and be located on the bottom surface of the base 5. This design allows a screwdriver or other tool to be directly inserted from the bottom of the base, making it easier to rotate the first fastener 6. The rear opening faces upward and is connected to the mounting hole 51, which ensures that when the first fastener 6 is tightened, it can effectively support the connecting plate 41 and ensure that the position of the limit hook 4 is stable.

[0037] The avoidance hole 42 designed on the limit hook 4 is designed to further consider the convenience of tool use. It is opposite to the threaded through hole 52, which allows the screwdriver to directly pass through the avoidance hole 42 and reach the notch of the first fastener 6. Such a design significantly reduces the difficulty of adjustment. The user does not have to struggle to find a suitable insertion point and angle in a narrow or hard-to-reach space, thereby reducing the time consumption and physical burden during installation and maintenance.

[0038] In summary, this design takes into account the accessibility and operability of the tool, ensuring that even in a compact space, the first fastener 6 can be accurately and quickly rotated to adjust and fix the position of the limit hook 4. This provides great convenience for the user, allowing for rapid on-site adjustment, while also ensuring the reliability and stability of the entire device.

[0039] More specifically, the connecting plate 41 includes a left arm 411 and a right arm 412 forming a fork shape, and the upper end of the first fastener 6 is pressed in the groove between the left arm 411 and the right arm 412 to tighten the connecting plate 41 in the mounting hole 51. The left arm 411 and the right arm 412 form a groove for tightening. This groove is the junction point of the upper end of the first fastener 6. When the first fastener 6 is screwed into the threaded through hole 52, it can accurately hold the groove between the left arm 411 and the right arm 412, thereby achieving a firm fixation of the connecting plate 41. The fork-shaped connecting plate 41 is not only easy to fix, but also this structure makes the force more evenly distributed on the left arm 411 and the right arm 412, thereby improving the stability and durability of the entire structure. In addition, since the left arm 411 and the right arm 412 are combined with the first fastener 6 by pressing, this physical locking mechanism greatly reduces the possibility of loosening due to vibration or use, ensuring long-term reliable use.

[0040] More specifically, the base 5 is detachably mounted on the movable door panel 2. The detachable design of the base 5 facilitates installation and daily maintenance.

[0041] More specifically, a second fastener 7 for fixing and connecting the movable door panel 2 and the base 5 is provided between the movable door panel 2 and the base 5. The second fastener 7 is preferably a screw with a cap.

[0042] More specifically, the roller 3 is detachably mounted on the movable door panel 2. The detachable design of the roller 3 facilitates installation and daily maintenance.

[0043] More specifically, a bearing 31 is provided on the roller 3, and a third fastener 8 for fixing and connecting the movable door panel 2 and the bearing 31 is provided between the movable door panel 2 and the bearing 31. The third fastener 8 is preferably a screw with a cap.

[0044] More specifically, the cross section of the roller 3 is I-shaped and a matching groove 32 is provided at its end, and the matching groove 32 is inserted from top to bottom on the guide rail 1 and can roll along the guide rail 1. The I-shaped cross section design of the roller 3 and the matching groove 32 structure at the end are to ensure that the roller can accurately match the guide rail 1. The design of the matching groove 32 allows the roller 3 to be easily installed on the guide rail 1 from above and ensures its smooth rolling on the guide rail. The I-shaped cross section not only enhances the structural strength of the roller, but also optimizes its load distribution and reduces friction and wear during rolling.
