[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] like Figures 1 to 7 As shown, this utility model proposes a buffer assembly for sliding doors, including a slide rail 1. The slide rail 1 has an internally mounted groove 12, and a buffer 2 is installed in the groove 12. A wheel 3 is slidably connected to the outer wall of the slide rail 1. The wheel 3 is used to be installed on the sliding door. The characteristic is that the width of the buffer 2 is less than or equal to the width of the groove 12. The wheel 3 includes a fixing shell 301. An anti-jumping component 302 is installed on one side of the fixing shell 301. The anti-jumping component 302 is used to engage with the buffer 2. The anti-jumping component 302 can prevent the wheel 3 from jumping. The anti-jumping component 302 includes an anti-jumping post 3021. The length of the bottom long side of the anti-jumping post 3021 is less than or equal to the width of the groove 12.

[0031] When the sliding door closes, the wheel 3 moves along the slide rail 1 and engages with the buffer 2 installed in the slide rail groove 12 via the anti-jump component 302 on its mounting housing 301. Specifically, the anti-jump post 3021 in the anti-jump component 302 contacts the buffer 2 as the door approaches the fully closed position, gradually slowing down the wheel's movement speed and allowing the door to close smoothly and quietly. This design not only ensures the stability of the door during closing but also effectively prevents damage caused by sudden impacts. Since the width of the buffer 2 is designed to be less than or equal to the width of the groove 12, the installation and replacement of the buffer are simplified, allowing it to be placed in the groove 12 without requiring high-precision adjustments. Furthermore, the design of the anti-jump component 302 effectively avoids the risk of the wheel 3 jumping off the track during high-speed movement, enhancing the system's stability and durability. Overall, this improvement not only reduces installation difficulty and potential errors but also extends the lifespan of the sliding door buffer assembly, improving the user experience. The fixed housing 301 and the anti-jump component 302 are two separate parts, allowing for easy removal of the wheel 3 by simply separating the anti-jump component 302. Similarly, when installing the wheel 3, the user can first install the wheel 3 onto the slide rail 1, and then connect the anti-jump component 302 to the fixed housing 301 to complete the installation of the wheel 3 on the slide rail 1. This design reduces the difficulty of installation and removal. The anti-jump post 3021 is a consumable part, and its separate design from the fixed housing 301 allows for individual replacement of the anti-jump post 3021 if it is damaged, without needing to replace the entire wheel 3.

[0032] Furthermore, as a preferred embodiment of the invention and not a limitation thereof, the length of the groove 12 is equal to the length of the slide rail 1, and the side wall of the groove 12 is provided with a slot 11. The anti-jump post 3021 includes a locking block 3022, which is disposed on the side wall of the anti-jump post 3021 and engages with the slot 11. The length of the groove 12 is designed to be equal to the length of the slide rail 1. This means that the user can place the buffer 2 into the groove 12 at any position on the slide rail 1, without being limited to a fixed position. The locking block 3022 is located on the side wall of the anti-jump post 3021 and can engage with the slot 11 on the side wall of the groove 12. This design further enhances the stability and reliability of the component, allowing the anti-jump component 302 to be more firmly held in the track when the wheel 3 moves at high speed, avoiding any possible jumping or derailment. When it is necessary to remove the anti-jump component 302 from the groove 12, simply disconnect the anti-jump component 302 from the fixed housing 301, and then rotate the anti-jump component 302 ninety degrees to disengage the locking block 3022 from the slot 11. Since the length of the bottom long side of the anti-jump post 3021 is less than or equal to the width of the groove 12, the anti-jump component 302 can be easily removed from the groove 12 after rotating ninety degrees. This design makes the disassembly process simple and quick. When it is necessary to install the anti-jump component 302 into the groove 12, simply reverse the disassembly steps.

[0033] Furthermore, as a preferred embodiment of the present invention and not a limitation thereof, the fixed housing 301 has a second threaded hole 3013, and the anti-jump component 302 is fitted with a third bolt 3023. The third bolt 3023 is rotatably connected to the anti-jump component 302, and the third bolt 3023 is threadedly connected to the second threaded hole 3013. Through the threaded connection design of the third bolt 3023 and the second threaded hole 3013, the anti-jump component 302 can be firmly fixed to the fixed housing 301, avoiding loosening due to long-term use or external impact. Through the threaded connection of the third bolt 3023 and the second threaded hole 3013, users can more conveniently and quickly complete the installation and maintenance of the fixed housing 301 and the anti-jump component 302.

[0034] Furthermore, as a preferred embodiment of the invention and not a limitation thereof, the fixing shell 301 is provided with a docking portion 3012, which engages with the anti-jump member 302. The docking portion 3012 is a groove for accommodating the anti-jump member 302. When it is necessary to install the anti-jump member 302, the anti-jump member 302 is first aligned and inserted into the groove of the docking portion 3012, so that it is securely engaged. The groove provides guidance for the installation of the anti-jump member 302, preventing the anti-jump member 302 from being misaligned during installation.

[0035] Furthermore, as a preferred embodiment of the invention and not a limitation thereof, the buffer 2 includes a housing 21, the bottom of which is provided with a mating portion 214, and the groove 12 is provided with a connecting portion, the connecting portion engaging with the mating portion 214. Through the engaging design of the mating portion 214 and the connecting portion, the buffer 2 can be confined within the groove 12, preventing movement of the buffer 2. The engaging of the connecting portion and the mating portion 214 provides guidance for the installation of the buffer 2, ensuring that the buffer 2 can be accurately positioned during installation. This greatly simplifies the installation process and reduces operational difficulty and time.

[0036] Optionally, in some embodiments, the connecting part is a protrusion, and the mating part 214 is a groove that matches the shape of the protrusion. Both the housing 21 and the mating part 214 have a first threaded hole 212, in which a first bolt 213 is installed, and the first bolt 213 is threadedly connected to the first threaded hole 212. When the buffer 2 is installed in the groove 12, the protrusion inserts into the groove of the mating part 214, forming a stable snap-fit ​​structure. Through the snap-fit ​​design of the protrusion and the groove, and the threaded connection of the first bolt 213, the buffer 2 is firmly fixed within the groove 12, preventing movement or loosening due to long-term use or external impact. This dual fixing mechanism not only improves the overall stability of the system but also extends the service life of the components. The threaded connection of the first bolt 213 to the first threaded hole 212 simplifies the installation of the buffer 2, allowing installation to be completed without complex high-precision adjustments. Similarly, when the buffer 2 needs to be replaced or repaired, it can be easily disassembled by simply removing the first bolt 213 and separating the protrusion from the groove, reducing maintenance costs and complexity.

[0037] Optionally, in some embodiments, the connecting part is a groove, and the mating part 214 is a groove that matches the shape of the groove.

[0038] Furthermore, as a preferred embodiment of the present invention and not a limitation thereof, a damping element 22 is installed inside the housing 21. A push-pull head 221 is installed at one end of the damping element 22. A hook 222 is hinged to the push-pull head 221. A slider 2223 is installed on the side wall of the hook 222. An L-shaped groove 211 is formed in the inner cavity side wall of the housing 21, which is slidably connected to the slider 2223. A first protrusion 2221 is provided on one side of the top of the hook 222, and a second protrusion 2222 is provided on the other side of the top of the hook 222. A top cover 23 is installed on the top of the housing 21. The top cover 23 has a through groove 231 for accommodating the passage of the first protrusion 2221 and the second protrusion 2222. The damping element 22 is a hydraulic buffer. When the sliding door is open, the hydraulic damper is locked in place, and the slider 2223 is located at the downward-curving end of the L-shaped groove 211. The second protrusion 2222 is inclined into the groove 12 but does not protrude from it. When the sliding door is closed, it drives the wheel 3 to move. When it reaches the hook 222, the anti-jump post 3021 contacts the first protrusion 2221, pushing the hook 222 to slide along the L-shaped groove 211. The second protrusion 2222 protrudes from the L-shaped groove 211, gradually compressing the hydraulic damper, thereby achieving a smooth closing action. When the sliding door is opened, the anti-jump post 3021 contacts the second protrusion 2222, pushing the hook 222 to slide in the opposite direction and return to its initial position.

[0039] Optionally, in some embodiments, the damping element 22 is one or a combination of hydraulic and pneumatic dampers.

[0040] Furthermore, as a preferred embodiment of the invention and not a limitation thereof, the side wall of the top cover 23 is provided with a connector 232, and the side wall of the housing 21 is provided with a mating member 233, the mating member 233 being engaged with the connector 232. This facilitates the installation and removal of the top cover 23, thereby facilitating the maintenance of the buffer 2.

[0041] Further, as a preferred embodiment of the invention and not a limitation thereof, the fixing shell 301 includes an internally threaded cylinder 3014. A limiting ring 306 is installed on one side of the fixing shell 301. The limiting ring 306 has an opening 3061 for the internally threaded cylinder 3014 to pass through. A fixing wheel 310 is installed at one end of the internally threaded cylinder 3014. A fourth bolt 3101 is fitted inside the fixing wheel 310, and the fourth bolt 3101 is threadedly connected to the internally threaded cylinder 3014. The sliding door is installed between the limiting ring 306 and the fixing wheel 310. The specific installation process is as follows: First, a hole is made in the sliding door, the internally threaded cylinder 3014 is passed through the hole, and then the sliding door is clamped by the fixing wheel 310 and the limiting ring 306. The fourth bolt 3101 is used to connect and fasten the fixing wheel 310 and the limiting ring 306 to ensure that the sliding door is firmly fixed between them. Through the coordinated design of the internal threaded cylinder 3014, the fixed wheel 310, and the limiting retaining ring 306, the sliding door can be firmly fixed between the two and will not loosen or fall off during high-speed movement. The threaded connection between the fourth bolt 3101 and the internal threaded cylinder 3014 further enhances the fixing effect. The design of the fourth bolt 3101 allows the fixed wheel 310 to be installed and removed easily and quickly, facilitating the installation of the wheel 3 on the sliding door and also simplifying later maintenance.

[0042] Furthermore, as a preferred embodiment of the invention and not a limitation thereof, the fixed wheel 310 is fitted with a protective cover 311, and the fixed wheel 310 is threadedly connected to the protective cover 311. The threaded connection between the protective cover 311 and the fixed wheel 310 makes installation and disassembly very simple. Users only need to rotate the protective cover 311 to complete the installation or disassembly operation, without the need for complex tools or high-precision adjustments. The design of the protective cover 311 effectively prevents the fixed wheel 310 from being corroded by the external environment, such as dust and moisture, extending the service life of the fixed wheel 310, while also avoiding the exposure of the fourth bolt 3101, improving aesthetics.

[0043] Optionally, in some embodiments, a second bolt 3011 is fitted inside the side wall of the fixed housing 301, and the second bolt 3011 is rotatably connected to the side wall of the fixed housing 301. An adjusting shaft 304 is fitted outside the internally threaded cylinder 3014, and the adjusting shaft 304 is slidably connected to the internally threaded cylinder 3014. The adjusting shaft 304 has a fourth threaded hole 3041, and the fourth threaded hole 3041 is threadedly connected to the second bolt 3011. By rotating the second bolt 3011, the raising and lowering of the adjusting shaft 304 can be controlled, thereby controlling the raising and lowering of the sliding door. Through the threaded connection between the second bolt 3011 and the fourth threaded hole 3041, the user can adjust the height of the sliding door very precisely. This design allows for fine-tuning, ensuring that the sliding door operates smoothly under different ground conditions, improving the flexibility and adaptability of the sliding door. The sliding connection design between the adjusting shaft 304 and the internally threaded cylinder 3014 simplifies the installation process, allowing height adjustment to be completed without complex tools or high-precision adjustments.

[0044] Optionally, in some embodiments, a first roller 303 is installed on one side of the fixed housing 301, and a second roller 305 is installed on the other side of the fixed housing 301. Both the first roller 303 and the second roller 305 include a bearing 3052, and the bearing 3052 is fitted with a wheel housing 3051 that directly contacts the slide rail 1. This avoids direct friction between the fixed housing 301 and the slide rail 1. Through the design of the first roller 303 and the second roller 305, the sliding door no longer directly contacts the slide rail 1, but rolls through the wheel housing 3051. This design greatly reduces friction, making the sliding door slide more smoothly, reducing the difficulty of operation for users, and improving the user experience. Due to the reduction of direct friction, the wear of the slide rail 1 and the fixed housing 301 is significantly reduced, extending the service life of the system. At the same time, the design of the bearing 3052 further reduces the wear of the roller itself. Compared with direct friction, the rolling contact between the wheel housing 3051 and the slide rail 1 generates less noise. The roller design facilitates disassembly and replacement. If a roller becomes worn or damaged, the user can easily remove it and replace it with a new one without having to perform a major overhaul of the entire wheel 3.

[0045] Optionally, in some embodiments, the contact surface between the slide rail 1 and the wheel housing 3051 is a plane. The contact surface between the wheel housing 305 and the slide rail 1 is a plane.

[0046] Optionally, in some embodiments, the contact surface between the slide rail 1 and the wheel housing 3051 is an arc surface.

[0047] The contact surface between the wheel housing 305 and the slide rail 1 is an arc surface.

[0048] Optionally, in some embodiments, the limiting ring 306 is equipped with at least one connecting screw 3062, and the fixing shell 301 has at least one third threaded hole 3015 that is threadedly connected to the screw 3062.

[0049] Optionally, in some embodiments, a cover plate 307 is installed on one side of the limiting ring 30, a gasket 309 is provided between the cover plate 307 and the fixed wheel 310, and a washer 308 is provided on the adjusting shaft 304 to prevent the adjusting shaft 304 from directly contacting the sliding door.

[0050] Example 1:

[0051] This utility model proposes a buffer assembly for sliding doors, including a slide rail 1, a groove 12 with an inner groove 12, a buffer 2 installed in the groove 12, and a wheel 3 slidably connected to the outer wall of the slide rail 1. The wheel 3 is used to be installed on the sliding door. The characteristic is that the width of the buffer 2 is less than or equal to the width of the groove 12. The wheel 3 includes a fixing shell 301, and an anti-jumping component 302 is installed on one side of the fixing shell 301. The anti-jumping component 302 is used to engage with the buffer 2 and can prevent the wheel 3 from jumping. The anti-jumping component 302 includes an anti-jumping post 3021, and the length of the bottom long side of the anti-jumping post 3021 is less than or equal to the width of the groove 12.

[0052] When the sliding door closes, the wheel 3 moves along the slide rail 1 and engages with the buffer 2 installed in the slide rail groove 12 via the anti-jump component 302 on its mounting housing 301. Specifically, the anti-jump post 3021 in the anti-jump component 302 contacts the buffer 2 as the door approaches the fully closed position, gradually slowing down the wheel's movement speed and allowing the door to close smoothly and quietly. This design not only ensures the stability of the door during closing but also effectively prevents damage caused by sudden impacts. Since the width of the buffer 2 is designed to be less than or equal to the width of the groove 12, the installation and replacement of the buffer are simplified, allowing it to be placed in the groove 12 without requiring high-precision adjustments. Furthermore, the design of the anti-jump component 302 effectively avoids the risk of the wheel 3 jumping off the track during high-speed movement, enhancing the system's stability and durability. Overall, this improvement not only reduces installation difficulty and potential errors but also extends the lifespan of the sliding door buffer assembly, improving the user experience. The fixed housing 301 and the anti-jump component 302 are two separate parts, allowing for easy removal of the wheel 3 by simply separating the anti-jump component 302. Similarly, when installing the wheel 3, the user can first install the wheel 3 onto the slide rail 1, and then connect the anti-jump component 302 to the fixed housing 301 to complete the installation of the wheel 3 on the slide rail 1. This design reduces the difficulty of installation and removal. The anti-jump post 3021 is a consumable part, and its separate design from the fixed housing 301 allows for individual replacement of the anti-jump post 3021 if it is damaged, without needing to replace the entire wheel 3.

[0053] The length of the groove 12 is equal to the length of the slide rail 1. A slot 11 is provided on the side wall of the groove 12. The anti-jump post 3021 includes a locking block 3022, which is located on the side wall of the anti-jump post 3021 and engages with the slot 11. The length of the groove 12 is designed to be equal to the length of the slide rail 1. This means that the user can place the buffer 2 into the groove 12 at any position on the slide rail 1, without being limited to a fixed position. The locking block 3022 is located on the side wall of the anti-jump post 3021 and can engage with the slot 11 on the side wall of the groove 12. This design further enhances the stability and reliability of the component, allowing the anti-jump component 302 to be more firmly held within the track when the wheel 3 moves at high speed, avoiding any possible jumping or derailment. When it is necessary to remove the anti-jump component 302 from the groove 12, simply disconnect the anti-jump component 302 from the fixed housing 301, then rotate the anti-jump component 302 ninety degrees to disengage the locking block 3022 from the slot 11. Because the length of the bottom long side of the anti-jump post 3021 is less than or equal to the width of the groove 12, the anti-jump component 302 can be easily removed from the groove 12 after being rotated 90 degrees. This design makes the disassembly process simple and quick. When it is necessary to install the anti-jump component 302 into the groove 12, simply reverse the disassembly steps.

[0054] The fixed housing 301 has a second threaded hole 3013, and the anti-jump component 302 is fitted with a third bolt 3023. The third bolt 3023 is rotatably connected to the anti-jump component 302, and the third bolt 3023 is threadedly connected to the second threaded hole 3013. Through the threaded connection design of the third bolt 3023 and the second threaded hole 3013, the anti-jump component 302 can be firmly fixed to the fixed housing 301, avoiding loosening due to long-term use or external impact. The threaded connection of the third bolt 3023 and the second threaded hole 3013 allows users to more conveniently and quickly complete the installation and maintenance of the fixed housing 301 and the anti-jump component 302. The fixed housing 301 is provided with a mating part 3012, which engages with the anti-jump component 302. The mating part 3012 is a groove for accommodating the anti-jump component 302. When installing the anti-jump component 302, first align the anti-jump component 302 and insert it into the groove of the mating part 3012, so that they are securely engaged. The groove provides guidance for the installation of the anti-jump component 302, preventing it from shifting during installation.

[0055] The buffer 2 includes a housing 21, with a mating part 214 at the bottom of the housing 21 and a connecting part in the groove 12. The connecting part engages with the mating part 214. Through this engagement design, the buffer 2 is confined within the groove 12, preventing movement. The engagement of the connecting part with the mating part 214 provides guidance for the installation of the buffer 2, ensuring accurate positioning during installation. This greatly simplifies the installation process and reduces operational difficulty and time. The mating part 214 is a groove that matches the shape of the protrusion. Both the housing 21 and the mating part 214 have a first threaded hole 212. A first bolt 213 is installed in the first threaded hole 212, and the first bolt 213 is threadedly connected to the first threaded hole 212. When the buffer 2 is installed in the groove 12, the protrusion inserts into the groove of the mating part 214, forming a stable engagement structure. Through the snap-fit ​​design between the protrusion and the groove, and the threaded connection of the first bolt 213, the buffer 2 is firmly secured within the groove 12, preventing movement or loosening due to long-term use or external impact. This dual-fixing mechanism not only improves the overall stability of the system but also extends the service life of the components. The threaded connection between the first bolt 213 and the first threaded hole 212 simplifies the installation of the buffer 2, allowing installation to be completed without complex high-precision adjustments. Similarly, when the buffer 2 needs to be replaced or repaired, it can be easily disassembled by simply removing the first bolt 213 and separating the protrusion from the groove, reducing maintenance costs and complexity.

[0056] A damping element 22 is installed inside the housing 21. A push-pull head 221 is installed at one end of the damping element 22, and a hook 222 is hinged to the push-pull head 221. A slider 2223 is installed on the side wall of the hook 222. An L-shaped groove 211 is opened on the inner cavity side wall of the housing 21 to slide with the slider 2223. A first protrusion 2221 is provided on one side of the top of the hook 222, and a second protrusion 2222 is provided on the other side of the top of the hook 222. A top cover 23 is installed on the top of the housing 21. The top cover 23 has a through groove 231 for accommodating the passage of the first protrusion 2221 and the second protrusion 2222. The damping element 22 is a hydraulic buffer. When the sliding door is open, the hydraulic buffer is locked in place, with the slider 2223 positioned at the downward-curving end of the L-shaped groove 211. The second protrusion 2222 is inclined into the groove 12 but does not protrude from it. When the sliding door is closed, the door drives the wheel 3 to move. When the wheel reaches the hook 222, the anti-jump post 3021 contacts the first protrusion 2221, pushing the hook 222 to slide along the L-shaped groove 211. The second protrusion 2222 protrudes from the L-shaped groove 211, gradually compressing the hydraulic buffer and thus achieving a smooth closing action. When the sliding door is opened, the anti-jump post 3021 contacts the second protrusion 2222, pushing the hook 222 to slide in the opposite direction and return to its initial position. The side wall of the top cover 23 is provided with a connector 232, and the side wall of the housing 21 is provided with a mating part 233, which engages with the connector 232. This facilitates the installation and removal of the top cover 23, thereby facilitating the maintenance of the buffer 2.

[0057] The fixed housing 301 includes an internally threaded cylinder 3014. A limiting ring 306 is installed on one side of the fixed housing 301. The limiting ring 306 has an opening 3061 for the internally threaded cylinder 3014 to pass through. A fixed wheel 310 is installed at one end of the internally threaded cylinder 3014. A fourth bolt 3101 is fitted inside the fixed wheel 310 and is threadedly connected to the internally threaded cylinder 3014. The sliding door is installed between the limiting ring 306 and the fixed wheel 310. The specific installation process is as follows: First, a hole is made in the sliding door, the internally threaded cylinder 3014 is passed through the hole, and then the sliding door is clamped by the fixed wheel 310 and the limiting ring 306. The fourth bolt 3101 is used to connect and tighten the fixed wheel 310 and the limiting ring 306 to ensure that the sliding door is firmly fixed between them. Through the coordinated design of the internal threaded cylinder 3014, the fixed wheel 310, and the limiting retaining ring 306, the sliding door can be firmly fixed between the two and will not loosen or fall off during high-speed movement. The threaded connection between the fourth bolt 3101 and the internal threaded cylinder 3014 further enhances the fixing effect. The design of the fourth bolt 3101 allows the fixed wheel 310 to be installed and removed easily and quickly, facilitating the installation of the wheel 3 on the sliding door and simplifying later maintenance. The fixed wheel 310 is covered with a protective cover 311, and the fixed wheel 310 is threadedly connected to the protective cover 311. The threaded connection between the protective cover 311 and the fixed wheel 310 makes the installation and removal process very simple. Users only need to rotate the protective cover 311 to complete the installation or removal operation without the need for complicated tools or high-precision adjustments. The design of the protective cover 311 effectively prevents the fixed wheel 310 from being corroded by the external environment, such as dust and moisture, extending the service life of the fixed wheel 310, while also avoiding the exposure of the fourth bolt 3101 and improving aesthetics.

[0058] The implementation method of Example 2 is as follows:

[0059] The difference between Embodiment 2 and Embodiment 1 lies in the following: a second bolt 3011 is fitted inside the side wall of the fixed housing 301, and the second bolt 3011 is rotatably connected to the side wall of the fixed housing 301. An adjusting shaft 304 is fitted outside the internally threaded cylinder 3014, and the adjusting shaft 304 is slidably connected to the internally threaded cylinder 3014. The adjusting shaft 304 has a fourth threaded hole 3041, which is threadedly connected to the second bolt 3011. By rotating the second bolt 3011, the raising and lowering of the adjusting shaft 304 can be controlled, thereby controlling the raising and lowering of the sliding door. Through the threaded connection between the second bolt 3011 and the fourth threaded hole 3041, the user can adjust the height of the sliding door very precisely. This design allows for fine-tuning, ensuring that the sliding door operates smoothly under different ground conditions, improving the flexibility and adaptability of the sliding door. The sliding connection design between the adjusting shaft 304 and the internally threaded cylinder 3014 simplifies the installation process, allowing height adjustment to be completed without complex tools or high-precision adjustments.

[0060] A first roller 303 is mounted on one side of the fixed housing 301, and a second roller 305 is mounted on the other side. Both the first roller 303 and the second roller 305 include a bearing 3052, and the bearing 3052 is fitted with a wheel housing 3051 that directly contacts the slide rail 1. This design avoids direct friction between the fixed housing 301 and the slide rail 1. Through the design of the first roller 303 and the second roller 305, the sliding door no longer directly contacts the slide rail 1, but rolls through the wheel housing 3051. This design greatly reduces friction, making the sliding door slide more smoothly, reducing the difficulty of operation for users, and improving the user experience. Due to the reduction of direct friction, the wear on the slide rail 1 and the fixed housing 301 is significantly reduced, extending the system's service life. At the same time, the design of the bearing 3052 further reduces the wear of the rollers themselves. Compared to direct friction, the rolling contact between the wheel housing 3051 and the slide rail 1 generates less noise. The roller design facilitates disassembly and replacement. If a roller becomes worn or damaged, the user can easily disassemble and replace it with a new one without requiring extensive repairs to the entire wheel 3. The contact surface between the slide rail 1 and the wheel housing 3051 is flat. The contact surface between the wheel housing 305 and the slide rail 1 is flat.

[0061] The implementation method of Example 3 is as follows:

[0062] The difference between Embodiment 3 and Embodiment 2 is that the contact surface between the slide rail 1 and the wheel housing 3051 is an arc surface. The contact surface between the wheel housing 305 and the slide rail 1 is an arc surface.

[0063] Specifically, the working principle of this utility model is as follows:

[0064] When the sliding door closes, the wheel 3 moves along the slide rail 1 and engages with the buffer 2 installed in the slide rail groove 12 via the anti-jump component 302 on its mounting housing 301. Specifically, the anti-jump post 3021 in the anti-jump component 302 contacts the buffer 2 when the door is near the fully closed position, thereby gradually slowing down the movement speed of the wheel 3, allowing the door to close smoothly and quietly. The design of the anti-jump component 302 effectively avoids the risk of the wheel 3 jumping off the track during high-speed movement, enhancing the stability and durability of the component. In addition, the buffer 2 engages with the connecting part in the groove 12 via the mating part 214, ensuring that it is firmly fixed in the groove 12 and preventing movement or loosening due to long-term use or external impact.

[0065] The fixed housing 301 includes an internally threaded cylinder 3014, with a limiting ring 306 installed on one side. The limiting ring 306 has an opening 3061 for the internally threaded cylinder 3014 to pass through. A fixed wheel 310 is installed at one end of the internally threaded cylinder 3014, and a fourth bolt 3101 is fitted inside the fixed wheel 310, which is threadedly connected to the internally threaded cylinder 3014. The sliding door is secured by a hole made in the door, through which the internally threaded cylinder 3014 is passed, and then clamped by the fixed wheel 310 and the limiting ring 306, ensuring that the sliding door is firmly fixed between them. This design not only improves the stability of the system but also facilitates the installation and removal of the wheel 3, simplifying the maintenance process.

[0066] A damping element 22 (hydraulic buffer) is installed inside the housing 21. A push-pull head 221 is mounted at one end of the push-pull head 221, which is hinged to a hook 222. A slider 2223 is mounted on the side wall of the hook 222, and an L-shaped groove 211 is formed on the inner side wall of the housing 21 to slide in conjunction with the slider 2223. When the sliding door is closed, the wheel 3 drives the anti-jump post 3021 to contact the first protrusion 2221 of the hook 222, pushing the hook 222 to slide along the L-shaped groove 211, gradually compressing the hydraulic buffer and achieving a smooth closing action. When the sliding door is opened, the anti-jump post 3021 contacts the second protrusion 2222, pushing the hook 222 to slide in the opposite direction, returning to its initial position. The top cover 23 is engaged with the mating part 233 of the housing 21 via a connector 232, facilitating the installation and removal of the top cover 23 and the maintenance of the buffer 2.

[0067] In summary, this utility model solves the problems of inconvenient installation and maintenance of traditional sliding door buffer components.
