Description
Technical Field
[0001] This utility model relates to the field of refrigerator drawer technology, specifically to a refrigerator drawer slide support. Background Technology
[0002] Most refrigerators have a crisper drawer on the top shelf. This drawer makes it easy to access food, and the drawer openings often have dividers to help keep fruits and vegetables fresh. In addition, the freezer compartment is also often designed as a drawer. However, because the freezer drawers have a larger volume than the top shelf, the slide rails of the freezer drawers bear a greater load.
[0003] Announcement No. CN220083437U discloses a refrigerator drawer slide bracket in the field of refrigerator technology. It includes a pair of fixed guide rails, with movable guide rails movably connected to the sides of the fixed guide rails via limiting components. The movable guide rails have mounting holes on their sides, with spring pins passing through the holes. Connecting shafts are welded to the sides of the two movable guide rails, and a drawer is movably inserted through one end of each connecting shaft. A drain plate is detachably snapped onto the front bottom of the drawer. This utility model, by setting a slide bracket that supports drawer rotation, increases the drawer's movement distance through the relative sliding of the movable and fixed guide rails. Simultaneously, the tangential connection between the elongated groove and the connecting shaft allows the refrigerator drawer to rotate vertically after extending from the fixed guide rails without disassembling the drawer, facilitating regular cleaning and improving the convenience of daily refrigerator drawer cleaning.
[0004] While existing technologies allow refrigerator drawers to rotate vertically after extending from the guide rails without disassembling the drawers, a significant problem exists in practical use. To maintain a low-temperature environment, refrigerators, especially freezers, are typically set at low temperatures, sometimes as low as -10 or -20 degrees Celsius. In such low temperatures, when there's a temperature difference between the inside and outside of the refrigerator, and humid air enters, moisture easily condenses into ice inside the guide rails. Once ice forms inside the rails, the friction between the rails and the sliders increases significantly, making the smooth sliding process extremely difficult. The drawer becomes hard to pull out smoothly, often requiring considerable force to open, and may even damage the drawer or guide rails due to excessive force. Furthermore, ice can cause the sliders to jam inside the rails, preventing normal movement and making the drawer completely impossible to open, severely impacting the user experience. Therefore, this paper proposes a refrigerator drawer guide rail to solve these problems. Utility Model Content
[0005] The purpose of this invention is to provide a slide rail bracket for a refrigerator drawer to solve the problems mentioned in the background art.
[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:
[0007] A refrigerator drawer slide support includes a refrigerator cabinet. The inner wall of the refrigerator cabinet is provided with a movable component for conveniently pulling out the drawer. The movable component includes a drawer, and racks are fixedly connected to both sides of the drawer. A slide groove is opened inside the refrigerator cabinet, and a connecting block is slidably connected inside the slide groove. A fixing block is fixedly connected to one side of the connecting block, and a rotating rod is rotatably connected inside the fixing block. A gear is fixedly connected to the outer wall of the rotating rod, and one side of the gear meshes with one side of the rack. An auxiliary component is provided at the bottom of the drawer for cooperating with the movable component.
[0008] The above technical solution involves the coordinated operation of a refrigerator cabinet, rack and pinion mechanism, fixed block, rotating rod, gear, and connecting block. When the user pulls out the drawer, the rack and pinion mechanism on both sides of the drawer drives the gear meshing with it to rotate. The rotation of the gear is then transmitted through the rotation of the rotating rod within the fixed block, allowing the connecting block to slide stably within the refrigerator cabinet's groove. Compared to the traditional slide rail slider structure, this transmission method effectively reduces jamming caused by low-temperature icing. This is because the rack and pinion transmission method provides more stable contact and more even force transmission. Even if there is a small amount of ice in the slide rail, the rotation of the gear can overcome a certain amount of resistance, enabling the drawer to be easily pulled out. This greatly improves the ease of use of the drawer in low-temperature environments.
[0009] A further improvement of the present invention is that the auxiliary component includes a support block, a linkage rod is rotatably connected inside the support block, and an auxiliary wheel is fixedly connected to the outer wall of the linkage rod.
[0010] By adopting the above technical solution, the support block, linkage rod, and auxiliary wheel are designed to work together. The support block provides stable rotational support for the linkage rod. When the drawer moves, the linkage rod drives the auxiliary wheel to rotate. The rolling of the auxiliary wheel can further reduce the friction between the drawer and the refrigerator cabinet, making the drawer move more easily. Especially in low-temperature environments, the rolling of the auxiliary wheel can help overcome the friction increased by factors such as icing. Working in conjunction with the moving components, it ensures that the drawer can be smoothly pulled out and pushed in, extending the service life of the drawer and the slide support.
[0011] A further improvement of the present invention is that an auxiliary groove is provided inside the refrigerator cabinet, and the outer wall of the auxiliary wheel is slidably connected to the inside of the auxiliary groove.
[0012] By adopting the above technical solution, the auxiliary groove and auxiliary wheel cooperate with each other. The auxiliary wheel slides in the auxiliary groove, which ensures the stability and straightness of the drawer during movement. This design can prevent the drawer from deviating or shaking when it is pulled out or pushed in, thus improving the safety and reliability of the drawer. At the same time, the auxiliary groove can also protect the auxiliary wheel to a certain extent, reduce the impact of external debris on the auxiliary wheel, and ensure that the auxiliary wheel can always function properly.
[0013] A further improvement of this utility model is that: a spring is fixedly connected to the inner wall of the drawer, a buffer plate is fixedly connected to the top of the spring, and the outer wall of the buffer plate is movably connected to the inner wall of the drawer.
[0014] By adopting the above technical solution, the spring, buffer plate and drawer work together to absorb and buffer the impact force when the drawer is pushed in or pulled out quickly, reducing the collision and noise between the drawer and the refrigerator cabinet. The buffer plate further disperses the impact force, protects the internal structure of the drawer and the refrigerator cabinet and avoids damage due to violent collision. In addition, this buffer structure can also improve the user's comfort and make the operation of the drawer more gentle.
[0015] A further improvement of this utility model is that: a connecting frame is fixedly connected to the outer wall of the rack, and a scraper is fixedly connected to the outer wall of the connecting frame, with one side of the scraper contacting the inner wall of the refrigerator cabinet.
[0016] By employing the above technical solution, the connecting bracket, scraper, and refrigerator cabinet work together. When the drawer moves, the scraper moves along with the rack, and one side of the scraper is always in contact with the inner wall of the refrigerator cabinet. In this way, the scraper can promptly clean frost, moisture, and debris from the inner wall of the refrigerator cabinet, preventing them from accumulating near the slide rails and causing ice buildup or affecting the sliding of the drawer. This effectively reduces drawer jamming caused by problems such as icing, ensuring smooth drawer movement, and also helps maintain the cleanliness and hygiene of the refrigerator interior.
[0017] A further improvement of this utility model is that: both the connecting block and the refrigerator cabinet have screw holes inside, and bolts are threaded into the screw holes, so that the interior of the connecting block and the interior of the refrigerator cabinet are detachably connected by bolts.
[0018] By adopting the above technical solution, the user can flexibly adjust the position of the connecting block as needed during the installation process through the setting of screw holes, bolts and the refrigerator cabinet, to ensure accurate drawer installation. When the slide bracket malfunctions or needs to be replaced, the connecting block can be easily removed from the refrigerator cabinet for repair or replacement simply by unscrewing the bolts. This detachable connection method reduces maintenance costs and difficulty, and improves the maintainability and service life of the product.
[0019] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared with the prior art is: to realize the convenient pulling out of the drawer, which greatly improves the convenience of using the drawer in low temperature environment.
[0020] This utility model provides a slide rail support for a refrigerator drawer. Through the coordinated arrangement of a refrigerator cabinet, rack, fixed block, rotating rod, gear, and connecting block, when the user pulls the drawer, the racks on both sides of the drawer drive the meshing gears to rotate. The rotation of the gears is then transmitted through the rotation of the rotating rod within the fixed block, allowing the connecting block to slide stably within the refrigerator cabinet's slide rail. Compared to traditional slide rail slider structures, this transmission method effectively reduces jamming caused by low-temperature icing. Because the rack and pinion transmission provides more stable contact and more even force transmission, even with a small amount of ice in the slide rail, the rotation of the gears can overcome some resistance, enabling the drawer to be easily pulled out, greatly improving the drawer's usability in low-temperature environments.
[0021] This utility model provides a slide rail bracket for a refrigerator drawer. By setting up a support block, a linkage rod, and an auxiliary wheel in cooperation, the support block provides stable rotational support for the linkage rod. When the drawer moves, the linkage rod drives the auxiliary wheel to rotate. The rolling of the auxiliary wheel can further reduce the friction between the drawer and the refrigerator cabinet, making the drawer move more easily. Especially in low-temperature environments, the rolling of the auxiliary wheel can help overcome the friction increased by factors such as icing. Working in conjunction with the moving components, it ensures that the drawer can be smoothly pulled out and pushed in, extending the service life of the drawer and the slide rail bracket.
[0022] This utility model provides a slide rail bracket for a refrigerator drawer. By setting up a connecting bracket, a scraper, and a refrigerator cabinet in cooperation, when the drawer moves, the scraper moves along with the rack, and one side of the scraper is always in contact with the inner wall of the refrigerator cabinet. In this way, the scraper can promptly clean frost, moisture, and debris on the inner wall of the refrigerator cabinet, preventing them from accumulating near the slide rail and causing ice formation or affecting the sliding of the drawer. In this way, the drawer jamming caused by ice formation and other problems is effectively reduced, ensuring smooth drawer movement, and also helping to keep the inside of the refrigerator clean and hygienic.

[0028] The present invention will be further described in detail below with reference to embodiments:
[0029] Example 1
[0030] like Figure 1-4 As shown, this utility model provides a slide rail bracket for a refrigerator drawer, including a refrigerator cabinet 1. The inner wall of the refrigerator cabinet 1 is provided with a moving component for conveniently pulling out a drawer 2. The moving component includes the drawer 2. Both sides of the drawer 2 are fixedly connected to racks 3. The refrigerator cabinet 1 has a slide groove 4 inside. A connecting block 5 is slidably connected inside the slide groove 4. A fixing block 6 is fixedly connected to one side of the connecting block 5. A rotating rod 7 is rotatably connected inside the fixing block 6. A gear 8 is fixedly connected to the outer wall of the rotating rod 7. One side of the gear 8 meshes with one side of the rack 3. The bottom of the drawer 2 is provided with an auxiliary component for cooperating with the moving component. The auxiliary component includes a support block 9. A linkage rod 10 is rotatably connected inside the support block 9. An auxiliary wheel 11 is fixedly connected to the outer wall of the linkage rod 10.
[0031] In this embodiment, by setting up the refrigerator cabinet 1, rack 3, fixed block 6, rotating rod 7, gear 8, and connecting block 5 in cooperation, when the user pulls the drawer 2, the rack 3 on both sides of the drawer 2 drives the gear 8 that meshes with it to rotate. The rotation of the gear 8 is then transmitted through the rotation of the rotating rod 7 within the fixed block 6, allowing the connecting block 5 to slide stably within the slide groove 4 of the refrigerator cabinet 1. Compared with the traditional slide rail slider structure, this transmission method can effectively reduce the jamming phenomenon caused by low-temperature icing, because the contact method of the gear 8 and rack 3 transmission is more stable and the force transmission is more uniform. Even if there is a small amount of ice in the slide rail, the rotation of the gear 8 can overcome a certain resistance and achieve [the desired effect]. The convenient pull-out of drawer 2 greatly improves its usability in low-temperature environments. Through the cooperation of support block 9, linkage rod 10 and auxiliary wheel 11, support block 9 provides stable rotation support for linkage rod 10. When drawer 2 moves, linkage rod 10 drives auxiliary wheel 11 to rotate. The rolling of auxiliary wheel 11 can further reduce the friction between drawer 2 and refrigerator cabinet 1, making the movement of drawer 2 easier. Especially in low-temperature environments, the rolling of auxiliary wheel 11 can help overcome the friction increased by factors such as icing. Working in conjunction with the moving components, it ensures that drawer 2 can be smoothly pulled out and pushed in, extending the service life of drawer 2 and slide bracket.
[0032] Example 2
[0033] like Figure 1-4 As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the auxiliary component includes a support block 9, a linkage rod 10 is rotatably connected inside the support block 9, an auxiliary wheel 11 is fixedly connected to the outer wall of the linkage rod 10, a spring 13 is fixedly connected to the inner wall of the drawer 2, a buffer plate 14 is fixedly connected to the top of the spring 13, the outer wall of the buffer plate 14 is movably connected to the inner wall of the drawer 2, the spring 13 is fixedly connected to the inner wall of the drawer 2, the buffer plate 14 is fixedly connected to the top of the spring 13, the outer wall of the buffer plate 14 is movably connected to the inner wall of the drawer 2, and screw holes 17 are opened inside both the connecting block 5 and the refrigerator cabinet 1. Bolts 18 are threaded inside the screw holes 17, and the interior of the connecting block 5 and the interior of the refrigerator cabinet 1 are detachably connected by bolts 18.
[0034] In this embodiment, by setting the auxiliary groove 12 and the auxiliary wheel 11 in cooperation, the auxiliary wheel 11 slides within the auxiliary groove 12, ensuring the stability and straightness of the drawer 2 during movement. This design can prevent the drawer 2 from shifting or shaking when pulled out or pushed in, improving the safety and reliability of the drawer 2. At the same time, the auxiliary groove 12 can also protect the auxiliary wheel 11 to a certain extent, reducing the impact of external debris on the auxiliary wheel 11 and ensuring that the auxiliary wheel 11 can always function normally. By setting the spring 13, the buffer plate 14 and the drawer 2 in cooperation, when the drawer 2 is pushed in or pulled out quickly, the spring 13 can absorb and buffer the impact force, reducing the collision and noise between the drawer 2 and the refrigerator cabinet 1, while the buffer plate 14 further disperses the impact. The impact-absorbing structure protects the internal structure of drawer 2 and refrigerator cabinet 1 from damage caused by violent collisions. In addition, this cushioning structure can improve user comfort and make the operation of drawer 2 more gentle. By setting up the connecting bracket 15, scraper 16 and refrigerator cabinet 1 in cooperation, when drawer 2 moves, scraper 16 will move with rack 3, and one side of scraper 16 will always be in contact with the inner wall of refrigerator cabinet 1. In this way, scraper 16 can clean frost, moisture and debris on the inner wall of refrigerator cabinet 1 in time, preventing them from accumulating near the slide rail and causing ice formation or affecting the sliding of drawer 2. In this way, the phenomenon of drawer 2 getting stuck due to ice formation and other problems is effectively reduced, ensuring the smooth movement of drawer 2, and also helping to keep the inside of the refrigerator clean and hygienic.
[0035] The working principle of the slide rail bracket of refrigerator drawer 2 will be explained in detail below.
[0036] like Figure 1-4 As shown, when the user needs to pull out the refrigerator drawer 2, they manually apply a pulling force to the drawer 2. Since racks 3 are fixedly connected to both sides of the drawer 2, the racks 3 will move synchronously with the movement of the drawer 2. At this time, the gear 8 meshing with one side of the rack 3 starts to rotate under the drive of the rack 3. The gear 8 is fixed to the outer wall of the rotating rod 7, and the rotating rod 7 rotates in the fixed block 6. The fixed block 6 is connected to the inner wall of the refrigerator cabinet 1 through the connecting block 5. The connecting block 5 slides in the slide groove 4 opened inside the refrigerator cabinet 1. In this way, the meshing transmission of the gear 8 and rack 3 converts the linear motion of the drawer 2 into the rotation of the gear 8. And through the sliding of the connecting block 5 in the slide groove 4, it ensures that the drawer 2 is pulled out of the refrigerator cabinet 1 smoothly and steadily. When pushing the drawer 2 in, the process is reversed. The user pushes the drawer 2, the rack 3 moves in the opposite direction, drives the gear 8 to rotate in the opposite direction, and the connecting block 5 slides in the opposite direction in the slide groove 4, so that the drawer 2 returns smoothly to the refrigerator cabinet 1.
[0037] During the movement of drawer 2, the auxiliary components play a supporting and friction-reducing role. The support block 9 at the bottom of drawer 2 is rotatably connected to the linkage rod 10. The auxiliary wheel 11 on the outer wall of the linkage rod 10 slides in the auxiliary groove 12 opened inside the refrigerator cabinet 1. When drawer 2 moves, the auxiliary wheel 11 rotates with the linkage rod 10. The rolling auxiliary wheel 11 reduces the friction between drawer 2 and refrigerator cabinet 1, and the auxiliary groove 12 provides precise guidance for the auxiliary wheel 11, ensuring the stability and straightness of the movement of drawer 2 and preventing drawer 2 from deviating or shaking.
[0038] Meanwhile, the scraper 16, which is fixed to the outer wall of the rack 3 by the connecting bracket 15, moves with the drawer 2. One side of the scraper 16 contacts the inner wall of the refrigerator cabinet 1. During the movement of the drawer 2, the scraper 16 can clean the frost, moisture and debris on the inner wall of the refrigerator cabinet 1 in time, preventing these substances from accumulating near the slide rail and causing ice to form, thus ensuring the smooth movement of the drawer 2.
[0039] The connecting block 5 and the refrigerator cabinet 1 are detachably connected by bolts 18. When installing the slide bracket, the position of the connecting block 5 on the refrigerator cabinet 1 can be adjusted according to actual needs. The bolts 18 are screwed into the screw holes 17 inside the connecting block 5 and the refrigerator cabinet 1 to achieve a fixed connection between the two. When the slide bracket malfunctions or needs to be replaced, simply unscrew the bolts 18 to remove the connecting block 5 from the refrigerator cabinet 1 for easy repair or replacement.
[0040] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
