[0003] Currently, during the refrigerator assembly process, the drawer slides are first installed and connected to the side wall of the inner liner. Then, foaming is carried out between the refrigerator body and the inner liner to form a foam layer. However, during the foaming process, the foaming material is prone to leaking out from the connection between the drawer slides and the inner liner, resulting in poor foaming effect.

[0041] The refrigerator's interior contains an inner liner, with an insulating foam layer between the refrigerator body and the inner liner. Drawer slides are installed on the side walls of the inner liner to facilitate the installation of storage drawers. During refrigerator assembly, the drawer slides are first installed and connected to the side walls of the inner liner. Then, foam is applied between the refrigerator body and the inner liner to form a foam layer. However, during the foaming process, the foaming material is prone to leaking out from the connection point between the drawer slides and the inner liner, resulting in poor foaming performance.

[0042] To solve the above-mentioned technical problems, this application embodiment optimizes the fixed installation structure of the drawer guide rail 4 and the inner liner 1, and designs a knob 5 with a flange 8 and a cover 9. The drawer guide rail 4 can be fixedly installed on the inner liner 1 by the knob 5, and the flange 8 and the cover 9 can effectively seal the installation point of the drawer guide rail 4, thereby solving the problem of leakage of foaming material from the installation point of the drawer guide rail 4 during the foaming process of existing refrigerators.

[0043] In some embodiments, refer to Figures 1 to 6 As shown, this application provides a refrigerator drawer slide assembly. The refrigerator includes an inner liner 1, which forms a cooling compartment 10. One side of the inner liner 1 has an inlet 101 communicating with the cooling compartment 10, and the side of the inner liner 1 adjacent to the inlet 101 has a mounting hole 2 communicating with the cooling compartment 10. The drawer slide assembly 3 includes a drawer slide 4 and a knob 5. The drawer slide 4 is located on the side of the inner liner 1 adjacent to the cooling compartment 10, and the drawer slide 4 has a mounting post 6 passing through the mounting hole 2. The knob 5 includes a main body 7, a flange 8, and a cover 9 located on the side of the inner liner 1 facing away from the cooling compartment 10. The main body 7 surrounds the mounting post 6 and is detachably connected to the mounting post 6. The flange 8 and the cover 9 are located at both ends of the main body 7. The flange 8 is used to press against the inner liner 1 to seal the gap between the mounting post 6 and the mounting hole 2. The cover 9 can be opened and closed.

[0044] Specifically, the drawer slide assembly 3 includes a drawer slide 4 and a knob 5. The drawer slide 4 is located inside the inner liner 1 and is used to install the refrigerator drawer. The knob 5 is located outside the inner liner 1, that is, inside the foam cavity between the refrigerator body and the inner liner 1. The drawer slide 4 is provided with a mounting post 6, which passes through the mounting hole 2 on the inner liner 1 and extends into the body 7 of the knob 5 for connection.

[0045] The knob 5 comprises a body 7, a flange 8, and a cover 9. The body 7 is a cylindrical structure open at both ends and forms a detachable connection with the mounting post 6 of the drawer slide 4 (e.g., via threads or snaps), ensuring a secure installation of the drawer slide 4. The flange 8 is located at one end of the body 7 (e.g., the bottom end) and is used to press against the side wall of the inner liner 1 to seal the gap between the mounting post 6 and the mounting hole 2, preventing foam material from leaking out. The cover 9 is located at the other end of the body 7 (e.g., the top end) and can be opened and closed to facilitate alignment and connection between the knob body 7 and the mounting post 6 on the drawer slide 4.

[0046] During assembly, first open the flip cover 9 to allow the mounting post 6 of the drawer slide 4 to smoothly enter the body 7 of the knob 5 and make a firm connection. At the same time, the flange 8 of the knob 5 is tightly pressed against the side wall of the inner liner 1, effectively sealing the gap between the mounting post 6 and the mounting hole 2. Then, close the flip cover 9 to ensure a complete seal at the installation position.

[0047] Understandably, during the foaming process, because the mounting hole 2 is effectively sealed by the knob flange 8 and the flap 9 is closed, the foaming material will not leak from the mounting point of the drawer slide 4, thus ensuring a good foaming effect. Furthermore, this design eliminates the need for traditional sealing tape, simplifying the assembly process, improving efficiency, and reducing costs.

[0048] Therefore, the refrigerator drawer slide assembly provided in this application embodiment not only achieves stable installation of the drawer slide 4, but also effectively avoids the leakage problem of foam material, and has the characteristics of simple structure and easy installation.

[0049] In some embodiments, refer to Figures 2 to 6 As shown, the main body 7 is snapped into the mounting column 6.

[0050] For example, a protrusion can be provided on the mounting post 6 of the drawer slide 4, and a corresponding groove can be provided on the inner wall of the knob body 7. When the knob 5 is turned, the protrusion on the mounting post 6 can slide into the groove on the inner wall of the body 7, thereby achieving a secure connection between the drawer slide 4 and the knob 5. This snap-fit ​​method does not require additional fasteners such as screws, thus simplifying the assembly process.

[0051] If it is necessary to disassemble or adjust the position of the drawer slide 4, turn the knob 5 in the opposite direction. At this time, the protrusion on the mounting post 6 can be disengaged from the slot on the inner wall of the body 7, allowing the drawer slide 4 to be easily removed.

[0052] Of course, in some other examples, a slot can be provided on the mounting post 6 of the drawer slide 4, and a corresponding protrusion can be provided on the inner wall of the knob body 7. The snap-fit ​​process is the same as above, and will not be described in detail here.

[0053] Therefore, in this embodiment, the drawer slide 4 can be quickly installed and removed by simply turning the knob 5, effectively improving the efficiency of installation and removal, and eliminating traditional screws and other fasteners, making the overall design simpler and reducing manufacturing costs. Furthermore, the snap-fit ​​structure allows for a tight fit, ensuring the flange 8 is firmly pressed against the side wall of the inner liner 1, thus providing a better sealing effect during the foaming process and preventing leakage of the foam material.

[0054] In some embodiments, refer to Figures 2 to 6As shown, the inner wall of the main body 7 is provided with a first snap-fit ​​structure 11. The first snap-fit ​​structure 11 includes a guide part 12 and a limiting part 13 arranged circumferentially along the main body 7. The guide part 12 is connected to the limiting part 13. The limiting part 13 is provided with a snap-fit ​​groove 14 on the side facing away from the flange 8. The outer wall of the mounting column 6 is provided with a second snap-fit ​​structure. The second snap-fit ​​structure includes a snap-fit ​​protrusion 15. The snap-fit ​​protrusion 15 is used to snap into the snap-fit ​​groove 14 through the guide part 12.

[0055] Specifically, the first snap-fit ​​structure 11 can be a one-piece molded structure for ease of processing. The guide portion 12 mainly serves to guide, ensuring that the snap-fit ​​protrusion 15 of the mounting post 6 can be accurately aligned and enter the snap-fit ​​groove 14 during insertion. The limiting portion 13 is located on one side of the guide portion 12, and its main function is to provide a clear limiting point to effectively limit the snap-fit ​​protrusion 15, thereby preventing the mounting post 6 from being over-screwed in.

[0056] The snap-fit ​​protrusion 15 is located on the outer wall of the mounting post 6 and is designed to slide along the guide portion 12 and eventually be embedded in the snap-fit ​​groove 14 to complete the snap-fit.

[0057] Installation Process: When installing the drawer slide 4, first open the flip cover 9 and align the snap-fit ​​protrusion 15 on the mounting post 6 with the guide portion 12 of the main body 7. As you turn the knob 5, the snap-fit ​​protrusion 15 on the mounting post 6 slides smoothly along the guide portion 12 until it reaches the stop portion 13. When the snap-fit ​​protrusion 15 reaches the stop portion 12, it is guided into the snap-fit ​​groove 14, achieving a secure connection between the drawer slide 4 and the knob body 7. At this time, the flange 8 at the bottom of the main body 7 is tightly pressed against the side wall of the inner liner 1. After installation, close the flip cover 9 to ensure overall sealing and prevent leakage of the foam material.

[0058] Disassembly process: Press the knob 5 down toward the side wall of the inner liner 1 and turn the knob 5 in the opposite direction. The snap-fit ​​protrusion 15 on the mounting post 6 will come out of the snap-fit ​​groove 14 and slide along the guide part 12 until it is completely separated from the main body 7.

[0059] Therefore, the design of the guide portion 12 in this embodiment allows the snap-fit ​​protrusion 15 to smoothly enter and exit the snap-fit ​​groove 14, reducing the possibility of jamming and improving the user experience. Furthermore, the precise guiding and limiting design ensures that each installation achieves the expected results, thereby improving the reliability of the component. In addition, this application allows for quick installation and disassembly without additional tools, simplifying the assembly and disassembly process.

[0060] In some embodiments, refer to Figures 3 to 5As shown, the guide portion 12 has a first guide surface 16 on the side facing away from the flange 8, and the snap-fit ​​protrusion 15 has a second guide surface 17 on the side adjacent to the drawer guide rail 4 that cooperates with the first guide surface 16. Both the first guide surface 16 and the second guide surface 17 are curved surfaces.

[0061] Specifically, the first guide surface 16 is located on the upper side of the guide portion 12. The first guide surface 16 is designed as an arc surface, which can provide a smooth guide path and ensure that the snap-fit ​​protrusion 15 on the mounting post 6 does not encounter any obstruction when entering the snap-fit ​​groove 14.

[0062] The second guide surface 17 is located on the lower side of the snap-fit ​​protrusion 15. The second guide surface 17 is also designed as a curved surface and cooperates with the first guide surface 16 so that the two can smoothly transition when in contact, reducing friction and resistance.

[0063] Installation process: When knob 5 is turned, the second guide surface 17 of the locking protrusion 15 first contacts the first guide surface 16. Since both guide surfaces are curved, they form a natural guide path, helping the locking protrusion 15 to slide smoothly along the guide portion 12 until it reaches the locking groove 14. This design reduces the force required for insertion, making the installation process easier and smoother, and effectively preventing jamming.

[0064] Disassembly process: Press the knob 5 down toward the side wall of the inner liner 1, and then turn the knob 5 in the opposite direction. The locking protrusion 15 will disengage from the locking groove 14 and slide along the first guide surface 16 of the guide portion 12 until it separates. The arc-shaped design of the first guide surface 16 and the second guide surface 17 also plays a role in this process, ensuring that the locking protrusion 15 can be smoothly disengaged.

[0065] Therefore, the arc-shaped guide surface design in this embodiment significantly improves the smoothness of the installation and disassembly process between the drawer slide 4 and the knob 5, further avoiding jamming issues. This design not only improves user convenience but also enhances component reliability and assembly efficiency.

[0066] In some embodiments, refer to Figures 3 to 6 As shown, the limiting part 13 has a transition surface 18 on the side facing away from the flange 8. The transition surface 18 is connected between the first guide surface 16 and the snap-fit ​​groove 14. The snap-fit ​​protrusion 15 also has a stepped surface 19 on the side adjacent to the drawer guide rail 4. The stepped surface 19 includes an overlapping surface 20 and a stop surface 21. The overlapping surface 20 is used to overlap the transition surface 18, and the stop surface 21 is connected between the overlapping surface 20 and the second guide surface 17, and is used to stop the snap-fit ​​groove 14 on the side wall adjacent to the transition surface 18.

[0067] Specifically, the transition surface 18 is located on the upper side of the limiting part 13 and between the first guide surface 16 and the snap-fit ​​groove 14. It can be a horizontal straight surface, which plays a role in smooth transition.

[0068] The overlapping surface 20 can be a curved surface or a horizontal straight surface, used to overlap the transition surface 18 to ensure that the snap-fit ​​protrusion 15 can be stably placed in the snap-fit ​​position. The stop surface 21 can be a vertical plane, located between the overlapping surface 20 and the second guide surface 17, and stops on the side wall of the snap-fit ​​groove 14 adjacent to the transition surface 18. The stepped surface 19 structure can prevent the snap-fit ​​protrusion 15 from going too deep into the snap-fit ​​groove 14.

[0069] Installation process: The snap-fit ​​protrusion 15 on the mounting post 6 is first guided by the first guide surface 16 and smoothly slides towards the transition surface 18. When it reaches the snap-fit ​​groove 14 via the transition surface 18, the overlapping surface 20 of the snap-fit ​​protrusion 15 overlaps with the transition surface 18, while the stop surface 21 abuts against the side wall of the snap-fit ​​groove 14 adjacent to the transition surface 18. This design confines part of the snap-fit ​​protrusion 15 within the snap-fit ​​groove 14, reducing the depth to which the snap-fit ​​protrusion 15 fully enters the snap-fit ​​groove 14, thereby avoiding the problem of over-insertion.

[0070] Disassembly process: During disassembly, simply press down knob 5 slightly to disengage the overlapping surface 20 of the snap-fit ​​protrusion 15 from the transition surface 18, and the stop surface 21 from the side wall of the snap-fit ​​groove 14 adjacent to the transition surface 18. This will easily allow the snap-fit ​​protrusion 15 to disengage from the snap-fit ​​groove 14. Then, rotate knob 5 in the opposite direction, and the snap-fit ​​protrusion 15 will smoothly exit the main body 7 along the first guide surface 16, completing the disassembly operation.

[0071] Therefore, the stepped surface 19 design in this embodiment can ensure that the snap-fit ​​protrusion 15 is stable after installation, and can effectively limit the depth of the snap-fit ​​protrusion 15 into the snap-fit ​​groove 14, thereby simplifying the disassembly steps. Separation can be completed by simply pressing down the knob 5 slightly, which effectively improves the ease of use.

[0072] In some embodiments, refer to Figure 4 and Figure 5 As shown, along the direction from the bottom to the top of the main body 7, the end of the first guide surface 16 away from the transition surface 18 is lower than the end of the first guide surface 16 adjacent to the transition surface 18.

[0073] Specifically, the first guide surface 16 in this embodiment of the application is inclined. The purpose of this inclined design is to provide a natural guide ramp to help the snap-fit ​​protrusion 15 enter the snap-fit ​​groove 14 more smoothly during the screwing process.

[0074] During installation, the user aligns the snap-fit ​​protrusion 15 with the lower end of the first guide surface 16 and begins to turn the knob 5. As the knob 5 is rotated, the snap-fit ​​protrusion 15 gradually rises along the inclined first guide surface 16 until it reaches the snap-fit ​​groove 14. This upward movement reduces the force required for insertion, allowing the snap-fit ​​protrusion 15 to smoothly enter the snap-fit ​​groove 14 and preventing jamming.

[0075] Therefore, the first guide surface 16 with its inclined design in this application embodiment can improve the smoothness of the snap-fit ​​protrusion 15 screwing into the snap-fit ​​groove 14, and further optimize the installation process between the drawer guide rail 4 and the knob 5.

[0076] In some embodiments, refer to Figure 3 and Figure 4 As shown, at least two first snap-fit ​​structures 11 can be provided circumferentially on the inner wall of the knob body 7. Correspondingly, at least two second snap-fit ​​structures (snap-fit ​​protrusions 15) can be provided on the mounting post 6 of the drawer guide rail 4. The second snap-fit ​​structures and the first snap-fit ​​structures 11 are snapped together one by one. This design can effectively improve the installation stability of the drawer guide rail 4.

[0077] In some embodiments, refer to Figure 2 and Figure 4 As shown, the knob 5 also includes a limiting rod 22, which is connected radially to the inner wall of the body 7 adjacent to the flip cover 9 and is used to abut against the end of the mounting post 6 away from the drawer guide rail 4.

[0078] Specifically, when the knob 5 is turned into place, the limiting rod 22 can abut against the bottom end of the mounting post 6 away from the drawer guide rail 4, forming an additional limiting point, thereby ensuring that the snap-fit ​​protrusion 15 is firmly limited in the snap-fit ​​groove 14, improving the installation stability of the drawer guide rail 4.

[0079] In some embodiments, the body 7 is threadedly connected to the mounting post 6.

[0080] Specifically, the outer wall of the mounting column 6 is provided with external threads, and the inner wall of the main body 7 is provided with internal threads, which can form a tight connection with the external threads on the mounting column 6.

[0081] When installing the drawer slide 4, align the threaded mounting post 6 with the main body 7 and begin turning the knob 5. As the knob 5 rotates, the external thread on the mounting post 6 engages with the internal thread inside the main body 7, achieving a tight fit and ensuring reliable connection.

[0082] Therefore, the threaded connection method adopted in this application not only provides a stable and reliable fixing method, but also simplifies the installation and disassembly process.

[0083] In some embodiments, refer to Figure 4As shown, the flip cover 9 is connected to the main body 7 via a connecting part 23, the thickness of which is between 0.3 mm and 0.6 mm. For example, it can be 0.5 mm.

[0084] Specifically, when the thickness of the connecting part 23 is less than 0.3 mm, the structural strength of the connecting part 23 is low, making it prone to damage. When the thickness of the connecting part 23 is greater than 0.6 mm, the connecting part 23 is too thick, has poor flexibility, and requires more force to flip the cover 9, making it inconvenient for the user. Therefore, this application designs the thickness of the connecting part 23 to be between 0.3 mm and 0.6 mm. On the one hand, this ensures the structural strength of the connecting part 23 and improves its durability; on the other hand, it ensures the flexibility of the connecting part 23, allowing the cover 9 to be easily flipped open and closed, reducing the force required by the user during operation, thereby improving the convenience of installation and use.

[0085] In some embodiments, refer to Figure 4 As shown, a third guide surface 24 is arranged around one edge of the main body 7 near the flip cover 9, and a guide limiting rib 25 that cooperates with and is connected to the third guide surface 24 is provided on the side of the flip cover 9 facing the main body 7.

[0086] Specifically, the third guide surface 24 is located at the top edge of the main body 7 and is distributed in a ring shape. The third guide surface 24 can be designed as a chamfered surface with a certain tilt angle or curvature to facilitate the guidance and support of the guide limiting ribs 25 on the flip cover 9.

[0087] The guide rib 25 is located on the inner side of the flip cover 9, is ring-shaped, and cooperates with the third guide surface 24. The function of the guide rib 25 is to ensure that the flip cover 9 is accurately aligned with the main body 7 every time it is closed, avoiding poor sealing caused by positional deviation.

[0088] When the user needs to close the flip cover 9, they gently press it down, and the guide rib 25 gradually slides along the third guide surface 24 and fits tightly against the opening of the main body 7. This design ensures that the flip cover 9 can be precisely aligned and tightly seal the main body 7, improving the sealing performance and effectively preventing the problem of foam material leakage from the installation point.

[0089] In some embodiments, refer to Figure 2 and Figure 5 As shown, the cross-sectional area of ​​the flange 8 gradually decreases along the direction from the bottom to the top of the main body 7.

[0090] For example, the shape of the flange 8 can be roughly frustum-shaped, so that the flange 8 forms a sealing cover. This design can provide uniform and stable pressing force. When the flange 8 is pressed against the side wall of the inner liner 1, it can form a good sealing interface, effectively improving the sealing performance and thus preventing the foam material from leaking.

[0091] In some embodiments, refer to Figure 4 and Figure 5 As shown, the top outer wall of the main body 7 is provided with a buckle 26, and the edge of the flip cover 9 is provided with a retaining ring 27, which engages with the buckle 26.
