[0042] In related technologies, each drawer is usually equipped with an independent guide rail structure. This design results in a large number of parts, which in turn leads to a wide variety of materials required on the production line and complex assembly processes. This not only reduces production efficiency but also leads to high production costs. In addition, during the drawer pushing and pulling process, there is an offset between the drawer and the guide rail structure, resulting in excessive gaps. This causes the drawer to make a lot of noise and the drawer to derail, affecting the user experience.

[0043] The following is combined with Figures 1-6 The drawer slide structure, drawer slide system, and refrigerator of this utility model are described in embodiments. In this utility model embodiment, the above-described drawer slide structure and drawer slide system are applied to a refrigerator. Of course, in other embodiments, the drawer slide system can also be applied to cabinets, filing cabinets, drawer-type office desks, etc., that is, related products and equipment with pull-out and sliding functions can all use the above-described drawer slide structure and drawer slide system.

[0044] Understandably, referring to Figures 1 to 5 In this embodiment of the utility model, the drawer guide rail structure includes a guide rail plate 100, the guide rail plate 100 is provided with a first slide rail 210 and a second slide rail 220, and both the first slide rail 210 and the second slide rail 220 are used to slide with the corresponding drawer; wherein, the guide rail plate 100 is provided with a limiting structure 330 at both the first slide rail 210 and the second slide rail 220, and the limiting structure 330 is used to limit the gap between the drawer and the guide rail plate 100 in the drawer width direction.

[0045] According to the drawer guide rail structure of this utility model embodiment, at least a first slide rail 210 and a second slide rail 220 are integrated into the guide rail plate 100. The first slide rail 210 and the second slide rail 220 are slidably connected to the corresponding drawers, so that at least two drawers can share one guide rail plate 100 to slide. Compared with related technologies, this utility model has fewer parts, reduces the types of materials and assembly processes on the production line, improves production efficiency, and reduces production costs. Furthermore, by setting a limit structure 330 on the guide rail plate 100, noise caused by excessive gaps between the drawer and the left and right guide rail plates 100 in the drawer width direction during the drawer pulling process is prevented, as well as derailment is prevented, thus improving the user experience.

[0046] Specifically, in this embodiment of the present invention, the number of the first slide rail 210 and the second slide rail 220 is not limited. It can be understood that when the number of drawers is three, a third slide rail can also be provided on the guide rail plate 100. Correspondingly, the third slide rail is also provided with a limit structure 330.

[0047] It should also be noted that in this embodiment of the utility model, the guide rail plate 100 is integrally injection molded with the aforementioned first slide rail 210 and second slide rail 220. This means that in this embodiment, the guide rail plate 100 is a plastic part. Of course, in other embodiments, the guide rail plate 100 is a metal part, such as stainless steel, and this is not limited here. Alternatively, the first slide rail 210 and the second slide rail 220 can be fixedly connected to the guide rail plate 100 after they are each formed. This also reduces the number of drawer slide systems.

[0048] It is understood that, in this embodiment of the utility model, the drawer slide system includes a drawer slide structure and a drawer assembly. There are two guide rail plates 100, which are spaced apart. The drawer assembly is disposed between the two guide rail plates 100. The drawer assembly includes at least a first drawer 410 and a second drawer 420. The first slide rail 210 is slidably connected to the first drawer 410, and the second slide rail 220 is slidably connected to the second drawer 420.

[0049] Specifically, refer to Figures 4 to 6 In this embodiment of the utility model, two guide rail plates 100 are arranged opposite each other. When two or more drawers are installed, corresponding slide rails are installed on the guide rail plates 100 respectively. Therefore, two or more drawers share a set of drawer guide rail structures. Compared with related technologies, at least one set of drawer guide rail structures is saved. Therefore, in the production process, there are fewer parts, reducing the types of materials and assembly processes on the production line, improving production efficiency, and reducing production costs.

[0050] Understandably, referring to Figure 6In this embodiment of the utility model, the drawer guide rail system includes the drawer guide rail system of the second aspect embodiment above and the box liner 500, and the guide rail plate 100 is connected to the box liner 500.

[0051] It should be noted that, referring to Figure 1 , Figure 4 and Figure 5 In this embodiment of the utility model, the first slide rail 210 and the second slide rail 220 are arranged at intervals along the vertical direction of the guide plate 100, and the lengths of the first slide rail 210 and the second slide rail 220 are not equal in the length direction of the guide plate 100. In this embodiment, the length of the first slide rail 210 is shorter than the length of the second slide rail 220. Of course, this is not a limitation. In some embodiments, the lengths of the first slide rail 210 and the second slide rail 220 are equal.

[0052] Specifically, referring to 6, in this embodiment of the present invention, the refrigerator compartment 500 is equipped with two guide rails 100 spaced apart in the left and right directions. Figures 4 to 6 The first drawer 410 and the second drawer 420 are arranged vertically, and the depth and width of the first drawer 410 and the second drawer 420 are not the same. In this embodiment, the length of the first drawer 410 is longer than the length of the second drawer 420 located below it. Of course, in some other embodiments, the depth and width of the first drawer 410 and the second drawer 420 can be set to be the same.

[0053] This can be understood as referring to Figures 4 to 6 In this embodiment, both the first drawer 410 and the second drawer 420 have openings at the top. Of course, in some embodiments, the drawers may also have side openings, such as left-side or right-side openings, which are not limited here. Therefore, in this embodiment, the drawer opening is provided with a cover. In this embodiment, the cover located at the top can be detachably connected to the guide rail; of course, in other embodiments, the drawer and the cover are detachably connected, which are not limited here.

[0054] In this embodiment, refer to Figure 1 , Figure 4 and Figure 5 Since the length of the upper first drawer 410 is longer than the length of the lower second drawer 420, a connecting structure is provided on the guide rail plate 100 at the corresponding position of the second drawer 420. The lower cover is detachably connected to the connecting structure. The bottom of the first drawer 410 and the lower cover cooperate to cover the opening of the second drawer 420. This can make more efficient use of space, reduce the space waste that may be caused by setting the cover separately, and reduce production costs.

[0055] Specifically, refer to Figure 1 , Figure 4 and Figure 5 In this embodiment of the utility model, the connecting structure includes a first snap-fit ​​part and a second snap-fit ​​part. The first snap-fit ​​part is a first snap-fit ​​boss 110 integrally formed with the guide rail plate 100. A snap-fit ​​groove is provided on the front side of the first snap-fit ​​boss 110. The second snap-fit ​​part includes a second snap-fit ​​boss 120 integrally formed with the guide rail plate 100 and a snap-fit ​​post 130. The second snap-fit ​​boss 120 and the snap-fit ​​post 130 are spaced apart, and a snap-fit ​​recess is provided on the front side of the second snap-fit ​​boss 120. Therefore, by the cooperation of the snap-fit ​​groove, the snap-fit ​​groove and the snap-fit ​​post 130, the cover can be detachably connected to the guide rail plate 100, which is convenient for disassembly and assembly, and helps to cover the opening of the drawer below, reducing dust and debris from entering the drawer and keeping the interior clean.

[0056] Of course, in some embodiments, the guide rail plate 100 may also be provided with a connecting structure corresponding to the first drawer 410 located above, and the cover may be placed on the opening of the first drawer 410 through the connecting structure, which is not limited here.

[0057] Understandably, referring to Figure 6 In this embodiment of the present invention, the guide rail plate 100 is detachably connected to the box liner 500. In this embodiment, the guide rail plate 100 is detachably fixed to the box liner 500 by three screws; of course, the number of screws is not limited here. Alternatively, in some other embodiments of the present invention, the guide rail plate 100 may also be detachably fixed to the box liner 500 by means of clips or other methods.

[0058] It should be noted that in some other embodiments, the guide rail plate 100 can also be movably connected to the box liner 500, for example, it can be rotatable or slidable, which is not limited here.

[0059] Understandably, referring to Figure 1 , Figure 4 and Figure 5 In this embodiment of the utility model, at least one of the first slide rail 210 and the second slide rail 220 is a guide groove 230 provided along the length direction of the guide rail plate 100.

[0060] Specifically, refer to Figure 1 , Figure 4 and Figure 5 In this embodiment of the utility model, the first slide rail 210 and the second slide rail 220 are both guide grooves 230 arranged along the length direction of the guide rail plate 100.

[0061] It is understood that each drawer has sliding protrusions on both sides of its width direction; that is, the first drawer 410 has a first sliding protrusion 411, and the second drawer 420 has a second sliding protrusion 421. When the first slide rail 210 is a guide groove 230, it is inserted into and slidably connected to the corresponding first sliding protrusion 411; when the second slide rail 220 is a guide groove 230, it is inserted into and slides with the corresponding second sliding protrusion 421. The sliding protrusions slide relative to the guide groove 230 to accommodate the sliding of the corresponding drawer. It should be noted that the lower end surfaces of the first sliding protrusion 411 and the second sliding protrusion 421 that contact the guide groove 230 are arc surfaces to facilitate smooth sliding and reduce wear.

[0062] Specifically, in this embodiment, the sliding protrusion and the drawer are an integral structure, reducing assembly steps; the bottom of the sliding protrusion is rounded to facilitate smooth sliding. Of course, in other embodiments, the sliding protrusion can also be configured as a rotating roller, which is rotatably connected to the drawer and makes rolling contact with the guide groove 230.

[0063] It should be noted that in some other embodiments, one of the first slide rail 210 and the second slide rail 220 is a guide groove 230, and the other can be a mounting protrusion. Correspondingly, one drawer is provided with a sliding protrusion, and the other is provided with a sliding groove. For example, the first slide rail 210 is a guide groove 230 provided along the length direction of the guide rail plate 100, and the second slide rail 220 is a mounting protrusion provided along the length direction of the guide rail plate 100. In at least two drawers, the first drawer 410 is provided with a sliding protrusion that is slidably connected to the guide groove 230, and the second drawer 420 is provided with a sliding groove that is slidably connected to the mounting protrusion. This is not limited here.

[0064] Reference Figure 1 In this embodiment of the utility model, the guide groove 230 includes a first sliding surface 231 and a second sliding surface 232, and the first sliding surface 231 and the second sliding surface 232 have different heights.

[0065] Specifically, in this embodiment, the first sliding surface 231 is located at the rear of the bottom surface of the guide groove 230, and the second sliding surface 232 is located at the front of the bottom surface of the guide groove 230. The first sliding surface 231 is inclined downward, that is, the second sliding surface 232 is higher than the first sliding surface 231. Therefore, when the sliding protrusion slides back and forth relative to the guide groove 230, the drawer will be pulled out after being subjected to force. When the drawer is pushed to a certain position, it can also fall along the first sliding surface 231 to achieve automatic return to its original position.

[0066] Of course, in some other embodiments, the first sliding surface 231 may be higher than the second sliding surface 232, and can be set accordingly as needed. It should also be noted that in some embodiments, the bottom surface of the guide groove 230 may be horizontal, which is not limited here.

[0067] Specifically, refer to Figure 1 In this embodiment of the present invention, the guide groove 230 further includes a transition surface 233, one end of which is connected to the first sliding surface 231 and the other end is connected to the second sliding surface 232.

[0068] The above structure allows the sliding protrusion of the drawer to smoothly transition from the first sliding surface 231 to the second sliding surface 232 during the sliding process, reducing vibration and impact caused by height difference, reducing noise generated during sliding, and improving the operating environment.

[0069] Understandably, referring to Figures 1 to 3 In this embodiment of the utility model, the guide rail plate 100 is provided with at least a first stop structure 310 and a second stop structure 320. The first stop structure 310 is correspondingly provided with the first slide rail 210, and the second stop structure 320 is correspondingly provided with the second slide rail 220. The first stop structure 310 and the second stop structure 320 are both used to restrict the corresponding drawer from disengaging from the guide rail plate 100.

[0070] Specifically, refer to Figures 1 to 3 In this embodiment of the utility model, the first stop structure 310 and the second stop structure 320 are both located on the front side of the guide rail plate 100, that is, the first stop structure 310 is located on the front side of the opening of the guide groove 230 corresponding to the first slide rail 210, and the second stop structure 320 is located on the front side of the opening of the guide groove 230 corresponding to the second slide rail 220.

[0071] Reference Figures 1 to 3 When the drawer slides back and forth relative to the guide rail 100, the first stop structure 310 or the second stop structure 320 restricts the extreme position of the drawer when it is pulled out, so as to prevent the drawer from falling off the guide rail 100, ensure the safety of the drawer, avoid structural damage or deformation caused by excessive pulling out of the drawer, and extend the service life of the drawer.

[0072] Specifically, in this embodiment of the invention, the sliding protrusions on the two drawers overlap with the corresponding first stop structure 310 and second stop structure 320 in the vertical direction. In turn, when the drawers slide, the sliding protrusion of the first drawer 410 and the first stop structure 310 or the sliding protrusion of the second drawer 420 and the second stop structure 320 abut against each other through the side wall to limit the extreme position of the corresponding drawer when it is pulled out.

[0073] Specifically, in this embodiment of the utility model, the limiting structure 330 is a limiting groove, which is used to slide with the corresponding drawer to limit the gap between the drawer and the guide rail 100 in the width direction of the drawer.

[0074] Specifically, in this embodiment of the invention, at least one of the first stop structure 310 and the second stop structure 320 is provided with a limiting structure 330, i.e., a limiting groove, as shown in the reference. Figures 1 to 3 To control the gap between the drawer and the guide rail 100, both the first stop structure 310 and the second stop structure 320 are provided with limiting grooves, as shown in the figure. Figure 4 and Figure 5 The corresponding drawers are provided with flanges 430, that is, both the first drawer 410 and the second drawer 420 are provided with flanges 430. The flanges 430 are inserted and cooperate with the limiting grooves to ensure that the sliding protrusions on the first drawer 410 and the second drawer 420, which have different depths and widths, slide on the fixed guide grooves 230, so as to prevent noise caused by excessive gaps between the drawers and the left and right guide rails 100 during the process of pulling out the drawers, and to prevent derailment.

[0075] Of course, in some other embodiments, the first stop structure 310 may also be provided with a limit structure 330, and the second stop structure 320 may not be provided with a limit structure 330. The limit structure 330 and the second stop structure 320 are set separately, and can be set accordingly as needed.

[0076] It should also be noted that in some other embodiments of this utility model, the limiting structure 330 can also be a limiting protrusion, and both the first drawer 410 and the second drawer 420 are provided with limiting grooves. Alternatively, in some embodiments, the limiting structure 330 corresponding to the first slide rail 210 is a limiting groove, and the first drawer 410 is a limiting protrusion; while the limiting structure 330 corresponding to the second slide rail 220 is a limiting protrusion, and the second drawer 420 is a limiting groove, which can be set accordingly as needed.

[0077] Understandably, referring to Figures 1 to 3 In this embodiment of the utility model, at least one of the first stop structure 310 and the second stop structure 320 is configured as a cam, and the cam is provided with an arc surface.

[0078] Specifically, in this embodiment, both the first stop structure 310 and the second stop structure 320 are configured as cams, with the arc surface of the cam contacting the lower surface of the drawer and supporting the back-and-forth sliding of the drawer.

[0079] With the above design, a plastic part resembling a roller, namely a cam, is designed on the integrally formed guide rail plate 100. The arc surface of the cam contacts the lower surface of the drawer, and the arc surface of the cam makes the drawer move more smoothly during the back and forth sliding process, ensuring the smoothness of the drawer's push and pull and low noise. The above design can solve the problem of liner cracking and weak support caused by the sliding of high-capacity refrigerator drawers on the liner 500 rib, so as to give users a better experience.

[0080] Of course, in some other embodiments, the cam can also be detachably fixed to the guide rail plate 100 by screws, clips, etc. It should be noted that in this embodiment, a mating protrusion is provided at the front opening of the guide groove 230 to further cooperate with the limiting structure 330 to control the gap between the drawer and the guide rail plate 100 in the left and right direction.

[0081] It can be understood that, in this embodiment of the utility model, the first stop structure 310 and the second stop structure 320 not only limit the extreme position of the corresponding drawer when it is pulled out, but also control the gap between the drawer and the guide rail plate 100 through the limiting groove on them, realizing a multi-functional design, reducing the number of parts, simplifying the system structure, and optimizing space utilization.

[0082] Of course, in some other embodiments, the first stop structure 310 may also be a cam, and the second stop structure 320 may be a rectangular block, which is not limited here.

[0083] It should be noted that, referring to Figure 1 In this embodiment of the invention, the guide rail plate 100 is provided with a plurality of mold opening recesses 140, which are located between the first slide rail 210 and the second slide rail 220. By designing the mold opening recesses 140, the use of raw materials can be reduced, thereby lowering costs. In addition, in plastic injection molding, a reasonable design of the mold opening recesses 140 can reduce warping of the product caused by uneven cooling and improve the structural strength of the guide rail plate 100.

[0084] It should also be noted that, referring to Figure 4 and Figure 5 In this embodiment of the utility model, a plurality of reinforcing ribs 150 are vertically arranged on the side wall of the guide rail plate 100 away from the drawer to further improve the structural strength of the guide rail plate 100.

[0085] Finally, it should be noted that the above embodiments are only used to illustrate the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the embodiments, those skilled in the art should understand that various combinations, modifications, or equivalent substitutions of the technical solutions of the present utility model do not depart from the spirit and scope of the technical solutions of the present utility model and should be covered within the protection scope of the present utility model.
