Description

Technical Field

[0001] This utility model relates to the field of refrigeration equipment technology, and in particular to a refrigerator linkage device and a refrigerator. Background Technology

[0002] Refrigerator interlocking mechanisms are primarily used to link the refrigerator door and drawers. Current methods typically employ either sliding rails or magnetic attraction. However, sliding rails are more complex, prone to accumulating dirt, and require space within the refrigerator, reducing the drawer's usable volume. Magnetic attraction relies on the magnetic force of the magnetic components, but this method is susceptible to magnetic attenuation and insufficient attraction over time, leading to interlocking failure. Furthermore, it's not well-suited for drawers holding heavy items. Utility Model Content

[0003] Therefore, it is necessary to provide a refrigerator linkage device and refrigerator that is simple in structure, not prone to failure, does not occupy too much storage space, and has a stable linkage effect.

[0004] To solve the above-mentioned technical problems, this application provides the following technical solution:

[0005] A refrigerator linkage device for linking the refrigerator door and drawers, the refrigerator linkage device comprising:

[0006] A mounting bracket for installation on the refrigerator door, and it has a rotating groove;

[0007] A snap-fit ​​block, one end of which is rotatably connected to the rotating groove in the depth direction of the drawer, and the other end of which extends out of the rotating groove and has a snap-fit ​​part;

[0008] A first spring is arranged along the height direction of the drawer and installed in the rotating groove in the compression direction. One end of the first spring is fixed to the fixing base and the other end is fixed to the snap-fit ​​block.

[0009] In response to the elastic force of the first spring, the latching part can engage the drawer, so that the refrigerator door and the drawer are linked; in response to an external force, the latching block can rotate relative to the fixed base, and the first spring is stretched, so that the latching part releases the drawer.

[0010] Understandably, this application, by setting a fixed base, a snap-fit ​​block, and a first spring, utilizes the snap-fit ​​part of the snap-fit ​​block connected to the fixed base on the refrigerator door to snap and limit the drawer, and utilizes the elastic contraction force of the first spring on the snap-fit ​​block to stably limit the drawer, thus achieving stable linkage between the drawer and the refrigerator door. The structure is simple, does not occupy excessive refrigerator space, and is easy to maintain. Simultaneously, the snap-fit ​​block can rotate relative to the fixed base in response to external forces, causing the first spring to be in a stretched state. At this time, the first spring can act on the snap-fit ​​block, giving it a tendency to reset, so that the drawer and refrigerator door can re-link. Furthermore, the first spring is not prone to failure, thus extending the service life of the refrigerator linkage device.

[0011] In one embodiment, the number of the first springs is set to multiple, and the multiple first springs are spaced apart along the length of the drawer.

[0012] Understandably, the multiple first springs arranged at intervals along the length of the drawer can disperse the tensile force of the first springs on the locking block, avoid stress concentration that could cause the locking block to shift or jam, and improve the accuracy of the locking block's rotation, thereby ensuring the linkage effect of the refrigerator linkage device on the refrigerator door and drawer.

[0013] In one embodiment, a mounting post is provided in the rotating groove, and a mounting groove is provided on the mounting post. One end of the first spring is limited in the mounting groove, and the other end is connected to the snap-fit ​​block.

[0014] Understandably, confining one end of the first spring within the mounting groove increases the stability of its connection with the fixed base, thus preventing the first spring from detaching from the fixed base after long-term use and affecting the overall use of the refrigerator linkage device. In other words, the mounting post ensures the stability of the first spring's installation, thereby extending the service life of the refrigerator linkage device.

[0015] In one embodiment, the latching part protrudes from the latching block in the height direction of the drawer to form a latching groove with the latching block;

[0016] The latching groove has an inclined surface on the groove wall facing the fixing seat in the depth direction of the drawer.

[0017] Understandably, by setting the groove wall of the latching slot as a slope, when the drawer and the refrigerator door are linked, the drawer and the slope are in a state of face-to-face contact, thereby increasing the friction between the drawer and the refrigerator linkage device and preventing it from coming off when it moves with the refrigerator door. In other words, the setting of the slope ensures the linkage effect between the drawer and the refrigerator door.

[0018] In one embodiment, the refrigerator linkage device further includes a pushing mechanism, which is mounted on the fixed base along the depth direction of the drawer and has a pushing force along the depth direction of the drawer;

[0019] When the drawer is released by the latch, the pushing mechanism can push the drawer.

[0020] Understandably, the push-pull mechanism helps unlock the drawer from the refrigerator door, making it easier to take out the drawer to store items, thus improving the user experience of the refrigerator's linkage device.

[0021] In one embodiment, the pushing mechanism includes a push rod and a second spring. The fixed base has a mounting hole arranged along the depth direction of the drawer. The push rod is movably installed in the mounting hole. The second spring is fixedly received in the mounting hole in a pre-compressed manner, and one end of the second spring is used to abut against the refrigerator door, and the other end abuts against the push rod.

[0022] Understandably, the second spring is pre-compressed and fixedly housed in the mounting hole so that, while avoiding interference from the push mechanism with the drawer linkage, it can provide the pushing force to push the push rod to lock the drawer when it is necessary to unlock the drawer.

[0023] In one embodiment, the top rod has a flexible element at one end facing the drawer in the depth direction.

[0024] Understandably, the flexible design prevents the top rod from making rigid contact with the drawer and causing damage, further enhancing the user experience of the refrigerator's linkage mechanism.

[0025] In one embodiment, the pushing mechanism further includes a limiting block, and a limiting groove extending along the depth direction of the drawer is formed on the wall of the mounting hole. The limiting block is limited in the limiting groove and can move in the limiting groove along the depth direction of the drawer.

[0026] Understandably, the limit block prevents the jacking mechanism from dislodging from the mounting hole, thus ensuring the stability of the connection between the jacking mechanism and the fixed base.

[0027] In one embodiment, the number of the limiting blocks is set to multiple, and the multiple limiting blocks are spaced apart in the circumferential direction of the top rod. The number of limiting slots corresponds one-to-one with the number of limiting blocks and matches each other.

[0028] It is understandable that multiple limit blocks are set to limit the push rod at multiple positions in its circumferential direction, so as to avoid the phenomenon of tilting or shaking caused by unstable limit, which would affect its use.

[0029] This application also provides the following technical solutions:

[0030] A refrigerator includes a refrigerator door, a drawer, and a refrigerator linkage device as described in any of the above embodiments, wherein the drawer and the refrigerator door move synchronously through the refrigerator linkage device.

[0031] Compared with existing technologies, the refrigerator linkage device and refrigerator described herein, by setting a fixed base, a locking block, and a first spring, utilize the locking part of the locking block connected to the fixed base on the refrigerator door to lock and limit the drawer, and utilize the elastic contraction force of the first spring on the locking block to stably limit the drawer, thus achieving stable linkage between the drawer and the refrigerator door. The structure is simple, does not occupy too much refrigerator space, and is easy to maintain. Simultaneously, the locking block can rotate relative to the fixed base in response to external forces, causing the first spring to be in a stretched state. At this time, the first spring can act on the locking block, giving it a tendency to return to its original position, so that the drawer and the refrigerator door can re-link. Furthermore, the first spring is not prone to failure, thus extending the service life of the refrigerator linkage device. Attached Figure Description

The term "and / or" as used in this application includes any and all combinations of one or more of the associated listed items.

[0045] Please see Figures 1 to 5 This application provides a refrigerator, which includes a refrigerator door 202, a drawer 201 and a refrigerator linkage device 100, wherein the drawer 201 and the refrigerator door 202 move synchronously through the refrigerator linkage device 100.

[0046] Specifically, the refrigerator linkage device 100 includes a fixed base 10, a snap-fit ​​block 20, and a first spring 30. The fixed base 10 is used to install on the refrigerator door 202 and has a rotating groove 11. One end of the snap-fit ​​block 20 is rotatably connected to the rotating groove 11 in the depth direction x of the drawer 201, and the other end extends out of the rotating groove 11 and has a latching part 21. The first spring 30 is arranged along the height direction z of the drawer 201 and installed in the rotating groove 11 in a compressed direction. One end of the first spring 30 is fixed to the fixed base 10, and the other end is fixed to the snap-fit ​​block 20. In response to the elastic force of the first spring 30, the latching part 21 can latch the drawer 201 to make the refrigerator door 202 and the drawer 201 linked. In response to an external force, the snap-fit ​​block 20 can rotate relative to the fixed base 10 and make the first spring 30 stretch, so that the latching part 21 releases the drawer 201.

[0047] It should be explained that this application, by setting a fixed base 10, a snap-fit ​​block 20, and a first spring 30, utilizes the snap-fit ​​portion 21 of the snap-fit ​​block 20 connected to the fixed base 10 on the refrigerator door 202 to snap and limit the drawer 201, and utilizes the elastic contraction force of the first spring 30 on the snap-fit ​​block 20 to stably limit the drawer 201, thereby achieving stable linkage between the refrigerator door 202 and the drawer 201. That is, the user can directly rotate the snap-fit ​​block 20 to unlock the drawer 201 from the refrigerator door 202, which is convenient to operate, has a simple structure, does not take up too much space in the refrigerator, and is easy to maintain. At the same time, the snap-fit ​​block 20 can rotate relative to the fixed base 10 in response to external force, and cause the first spring 30 to be in a stretched state. At this time, the first spring 30 can act on the snap-fit ​​block 20, giving it a tendency to return to its original position, so that the refrigerator door 202 and the drawer 201 can be linked again. Moreover, the first spring is not easy to fail, which can extend the service life of the refrigerator linkage device 100.

[0048] like Figure 3As shown, the fixed base 10 also has two rotating holes 12, which are arranged opposite each other in the length direction y of the drawer 201; and the refrigerator linkage device 100 also includes a rotating shaft 13; wherein, both ends of the rotating shaft 13 pass through the snap-fit ​​block 20 and are rotatably limited within the two rotating holes 12. In this way, the snap-fit ​​block 20 can be rotated relative to the fixed base 10.

[0049] like Figure 1 and Figure 5 As shown, the latching part 21 protrudes from the latching block 20 in the height direction z of the drawer 201, forming a latching groove 22 with the latching block 20; wherein, the wall of the latching groove 22 facing the fixing seat 10 in the depth direction x of the drawer 201 is set as an inclined surface 221. It can be understood that the inner side of the drawer 201 near the refrigerator door 202 is usually set in an inclined shape. Therefore, setting the wall of the drawer 201 corresponding to the latching groove 22 as an inclined surface 221 can increase the friction between the drawer 201 and the latching part 21, preventing the drawer 201 from falling out of the latching groove 22 when it moves with the refrigerator door 202, thereby ensuring the linkage effect between the drawer 201 and the refrigerator door 202.

[0050] Please continue to refer to this. Figures 2 to 5 The number of first springs 30 is set to multiple, and the multiple first springs 30 are arranged at intervals along the length direction y of the drawer 201. In this way, the elastic force of the multiple first springs 30 on the locking block 20 can be distributed, avoiding stress concentration that may cause the locking block 20 to shift or jam, and improving the rotation accuracy of the locking block 20, thereby ensuring the linkage effect of the refrigerator linkage device 100 on the refrigerator door 202 and the drawer 201.

[0051] Here, the number of first springs 30 can be two, three, or five. Of course, it is not limited to this; the specific number of first springs 30 can be determined according to the actual situation. In this embodiment, two first springs 30 are used.

[0052] In one embodiment, a mounting post 40 is provided in the rotating groove 11, and a mounting groove 41 is formed on the mounting post 40. One end of the first spring 30 is limited in the mounting groove 41, and the other end is connected to the snap-fit ​​block 20. It can be understood that the setting of the mounting post 40 can not only increase the stability of the connection between the first spring 30 and the fixed seat 10, and prevent the first spring 30 from detaching from the fixed seat 10 after long-term use, thus affecting the overall use of the refrigerator linkage device, but also limit the first spring 30 through its mounting groove 41, preventing it from shifting in the height direction relative to the drawer 201, thereby ensuring the normal stretching or compression of the first spring 30.

[0053] like Figure 5As shown, the refrigerator linkage device 100 also includes a pushing mechanism 50, which is mounted on the fixed base 10 along the depth direction x of the drawer 201 and has a pushing force along the depth direction x of the drawer 201; wherein, when the latching part 21 releases the drawer 201, the pushing mechanism 50 can push the drawer 201. In this way, the pushing mechanism 50 can be used to help unlock the drawer 201 from the refrigerator door 202, so as to facilitate taking out the drawer 201 to store items, thus improving the user experience of the refrigerator linkage device 100.

[0054] Specifically, the pushing mechanism 50 includes a push rod 51 and a second spring 52. The fixed base 10 has a mounting hole 53 arranged along the depth direction x of the drawer 201. The push rod 51 is movably installed in the mounting hole 53. The second spring 52 is pre-compressed and fixedly housed in the mounting hole 53, with one end of the second spring 52 abutting against the refrigerator door 202 and the other end abutting against the push rod 51. In this way, the compression force of the second spring 52 can be used to drive the push rod 51 to move towards the drawer 201, thereby realizing the assisted release and unlocking of the drawer 201. When the refrigerator door 202 and the drawer 201 are linked, the pushing mechanism 50 is housed in the mounting hole 53, which can prevent the pushing mechanism 50 from affecting the linkage of the drawer 201.

[0055] In one embodiment, a flexible element 511 is provided at the end of the top rod 51 facing the drawer 201 in the depth direction x. It is understood that the flexible element 511 can prevent the top rod 51 from being damaged by rigid contact with the drawer 201, and further improve the user experience of the refrigerator linkage device 100.

[0056] Please continue to refer to this. Figure 5 The pushing mechanism 50 also includes a limiting block 54. A limiting groove 55 extending along the depth direction x of the drawer 201 is provided on the wall of the mounting hole 53. The limiting block 54 is confined within the limiting groove 55 and can move along the depth direction x of the drawer 201 within the limiting groove 55. Thus, the limiting groove 55 can limit the limiting block 54, preventing the pushing mechanism 50 from dislodging from the mounting hole 53 under the action of the second spring 52, thereby ensuring the connection stability between the pushing mechanism 50 and the fixed base 10.

[0057] Preferably, the number of limiting blocks 54 is set to multiple, and the multiple limiting blocks 54 are spaced apart in the circumferential direction of the push rod 51. The number of limiting grooves 55 corresponds one-to-one with the number of limiting blocks 54 and matches each other. In this way, the push rod 51 can be limited in its circumferential direction by multiple limiting blocks 54, so as to avoid the phenomenon of tilting or shaking caused by unstable limiting of the push rod 51, which would affect its use.

[0058] Here, the number of limit blocks 54 can be set to two, three, or five. Of course, it is not limited to this; the specific number of limit blocks 54 can be determined according to the actual situation. In this embodiment, the number of limit blocks 54 is set to two.

[0059] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0060] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the patent protection scope of this application should be determined by the appended claims.
