In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0022] Commercial display cases and freezers are becoming increasingly popular, and the market has higher and higher requirements for bottle display and brand image. Various beverages have different diameters; without beverage dividers, beverages of different diameters placed on the same shelf will appear messy and disorganized, negatively impacting the brand image. To achieve neater beverage display, dividers are generally used. However, the fixed spacing between dividers may result in some larger-diameter beverages not fitting, while smaller-diameter beverages may waste space. Currently, dividers are generally fixed with screws, requiring tools to disassemble and reposition them, making divider installation and removal relatively cumbersome.

[0023] To alleviate and solve the above technical problems, this utility model proposes a refrigerator shelf structure and a refrigerator. The refrigerator shelf structure includes a shelf 10 and a partition 20. Beverages, food and other products can be placed between two adjacent partitions 20. One end of the partition 20 is inserted into the shelf 10, and the other end is slidably connected to the shelf 10. When it is necessary to change the position of the partition 20 (adjust the distance between the two partitions 20), the insertion part 21 of the partition 20 is taken out from the shelf 10, and then the partition 20 is moved to the predetermined position and then the insertion part 21 of the partition 20 is inserted into the shelf 10.

[0024] The refrigerator shelf structure provided in the embodiments of this utility model will now be described.

[0025] Please refer to the following: Figure 1 and Figure 2 The refrigerator shelf structure includes: The shelf 10 has a first side and a second side spaced apart along a first direction. The first side of the shelf 10 is provided with a slot structure 14, which includes a plurality of slot units 141. The other side of the shelf 10 is provided with a slide rail 15. The arrangement direction of the plurality of slot units 141 and the length direction of the slide rail 15 are both parallel to the second direction. The first direction and the second direction are arranged at an angle. Multiple partition plates 20 are provided. The first end of the partition plate 20 is provided with an insertion part 21 for interlocking with one of the slot units 141. The second end of the partition plate 20 is provided with a sliding engagement part 22, which is slidably disposed on the slide rail 15.

[0026] The shelf 10 has a slot structure 14 and a slide rail 15 on its first and second sides, respectively. The slot structure 14 includes multiple slot units 141 arranged sequentially along a second direction, and the slide rail 15 also extends along the second direction. The first end of the partition plate 20 has a slot portion that mates with the slot unit 141, and the second end of the partition plate 20 has a sliding engagement portion 22 that mates with the slide rail 15. The insertion portion 21 can be inserted into each slot unit 141. Generally, multiple partition plates 20 can be installed on each shelf 10, and a goods passage is formed between two adjacent partition plates 20. The length direction of the goods passage is the same as the length direction (first direction) of the partition plate 20, and goods can slide outward from the goods passage.

[0027] When the position of the partition 20 needs to be adjusted, the partition 20 can be deformed, and the insertion part 21 of the partition 20 can be removed from the slot unit 141 of the shelf 10. Then, the partition 20 can be slid to the corresponding position, and then the partition 20 can be deformed again, so that the insertion part 21 can be inserted into the corresponding slot unit 141, thus completing the adjustment of the position of the partition 20. Alternatively, the sliding mating part 22 at the second end of the partition 20 can be removed from the slide rail 15, and then the insertion part 21 can be pulled out from the slot unit 141. After the partition 20 is adjusted to the appropriate position, it can be reinstalled. Therefore, no additional installation tools such as screwdrivers are required when adjusting the position of the partition 20, and the adjustment method is simple and effective.

[0028] The refrigerator shelf structure in the above embodiment includes a shelf 10 and a divider 20 disposed on the shelf 10. The insertion part 21 at the first end of the divider 20 is inserted into the slot unit 141 of the shelf 10, and the second end of the divider 20 is slidably connected to the slide rail 15 of the shelf 10. When the position of the divider 20 needs to be adjusted, the divider 20 can be deformed or the sliding mating part 22 can be removed from the slide rail 15, the insertion part 21 can be removed from the slot unit 141, the divider 20 can be moved to the corresponding position, and finally the divider 20 can be installed to achieve the adjustment of the divider 20's position. The shelf 10 and divider 20 used in this invention do not require disassembly tools when adjusting the position of the divider 20, thus improving the efficiency of the divider 20's position adjustment.

[0029] Please refer to some embodiments of this utility model. Figure 1 and Figure 2 The shelf 10 includes a first frame 11 disposed on a first side, a second frame 12 disposed on a second side, and a support plate 13 connecting the first frame 11 and the second frame 12. A slot structure 14 is disposed on the first frame 11, and a slide rail 15 is disposed on the second frame 12.

[0030] In some embodiments, the surface of the support plate 13 may be coated with Teflon to reduce friction and make it easier for goods to slide out.

[0031] In some embodiments, the support plate 13 is inclined, with the side away from the freezer door being higher and the side closer to the freezer door being lower, making it easier for goods to slide out. The direction from away from the freezer door to closer to the freezer door is the first direction.

[0032] Please refer to some embodiments of this utility model. Figure 2 and Figure 3 The slot structure 14 includes a first slot 1411 extending along a second direction and a second slot 1412 connected to the first slot 1411. There are multiple second slots 1412. Each slot unit 141 includes a second slot 1412 and a portion of the first slot 1411 connected to it. Each second slot 1412 is interconnected with the first slot 1411. It can be understood that the first slot 1411 is divided into multiple parts (each part is connected to a corresponding second slot 1412), and each part combined with its corresponding second slot 1412 forms a slot unit 141. Alternatively, it can be understood that adjacent slot units 141 are interconnected.

[0033] By setting a first groove 1411 and a plurality of second grooves 1412 connected to the first groove 1411, a plurality of groove units are formed in sequence. The center distance between two adjacent groove units is smaller, thereby making the position adjustment accuracy of the partition plate 20 higher.

[0034] In some embodiments, two adjacent slot units 141 are spaced apart from each other, and the insertion part 21 of the partition plate 20 can select the corresponding slot unit 141 for insertion.

[0035] Please refer to some embodiments of this utility model. Figure 3 The second slot 1412 extends along a third direction, which is perpendicular to the third direction, making the slot unit 141 T-shaped. The second direction is the arrangement direction of the multiple slot units 141. When the freezer shelf structure is in use, the second direction is the left-right direction of the freezer, the third direction is the height direction, and the insertion direction of the insertion part 21 is the first direction, which is the front-back direction of the freezer. In this way, when the insertion part 21 is located inside the insertion slot, it is limited at least in the second direction and the third direction. The slot unit 141 is T-shaped, and correspondingly, the insertion part 21 is also T-shaped, matching the slot unit 141.

[0036] By setting the slot unit 141 to a T-shape, the insertion relationship between the insertion part 21 and the slot unit 141 is made more stable, which can reduce the shaking of the insertion part 21 inside the slot unit 141 and improve stability.

[0037] In some embodiments, the first direction, the second direction, and the third direction are arranged perpendicular to each other.

[0038] Please refer to some embodiments of this utility model. Figure 7 and Figure 8 The insertion part 21 includes a first insertion segment 211 and a second insertion segment 212 connected to the middle of the first insertion segment 211. The first insertion segment 211 is inserted into the first slot 1411, and the second insertion segment 212 is inserted into the second slot 1412. The middle of the first insertion segment 211 refers to any position of the second insertion segment 212 other than the two ends. When the second insertion segment 212 is connected to the middle of the first insertion segment 211, the cross-section of the insertion part 21 can be T-shaped to fit the slot unit 141.

[0039] By setting a first insertion section 211 and a second insertion section 212 connected to the second insertion section 212, the cross-section of the insertion part 21 is T-shaped and interlocks with the slot unit 141, thereby realizing the insertion of the insertion part 21 of the partition plate 20 into the slot unit 141 of the shelf 10.

[0040] Please refer to some embodiments of this utility model. Figure 5 and Figure 6The sliding engagement part 22 is detachably snapped onto the slide rail 15. That is, the sliding engagement part 22 can be installed on the slide rail 15 by snapping, and the sliding engagement part 22 can also be removed from the slide rail 15. In this way, when adjusting the position of the partition plate 20, the second end of the partition plate 20 can be removed from the shelf 10, making it easier to adjust the position of the partition plate 20.

[0041] By detachably snapping the sliding engagement part 22 onto the slide rail 15, the sliding engagement part 22 can be stably connected to the slide rail 15 without external force, and can be removed from the slide rail 15 under external force, making it convenient to adjust the position of the partition plate 20.

[0042] In some embodiments, please refer to Figures 4 to 6 The slide rail 15 has a T-shaped or dovetail-shaped cross-section, allowing the sliding engagement part 22 to engage with the opposite sides of the slide rail 15. Simultaneously, at least part of the sliding engagement part 22 is an elastically deformable structure, allowing it to be removed from the slide rail 15 when subjected to external force.

[0043] In other embodiments, after the sliding fit part 22 is installed on the slide rail 15, it cannot be removed from the slide rail 15 by deforming the sliding fit part 22. Or, in order to avoid the sliding fit part 22 from repeatedly deforming and failing, the sliding fit part 22 can be inserted from one end of the slide rail 15 or from the mounting notch 152 on the slide rail 15.

[0044] Please refer to some embodiments of this utility model. Figures 4 to 6 The slide rail 15 has multiple spaced-apart stops 151, which limit the sliding engagement part 22 along the length of the slide rail 15. An installation space for the sliding engagement part 22 is formed between two adjacent stops 151. When installing the partition plate 20, the first end of the partition plate 20 is inserted into the slot unit 141, and the sliding engagement part 22 at the other end is engaged in the aforementioned installation space. The stops 151 limit the sliding engagement part 22. When removing the partition plate 20, the sliding engagement part 22 is first pulled off the slide rail 15, and then the insertion part 21 is pulled out of the slot unit 141.

[0045] By providing a stop 151, the position of the sliding mating part 22 in the length direction of the slide rail 15 can be limited, preventing the partition plate 20 from tilting excessively.

[0046] In some embodiments, the distance between two adjacent stop portions 151 matches the sliding engagement portion 22, and the length of the sliding engagement portion 22 is equal to or approximately equal to the distance between the two stop portions 151. After the sliding engagement portion 22 is assembled onto the slide rail 15, the sliding engagement portion 22 cannot move along the length direction of the slide rail 15.

[0047] In some embodiments, the distance between two adjacent stop portions 151 is greater than the length of the sliding engagement portion 22. After the sliding engagement portion 22 is assembled onto the slide rail 15, the sliding engagement portion 22 can move along the length direction of the slide rail 15 to achieve a small range of adjustment of the position of the partition plate 20.

[0048] Please refer to some embodiments of this utility model. Figure 4 The slide rail 15 has an installation notch 152, and the sliding mating part 22 is slidably installed on the slide rail 15 from the installation notch 152. When the second end of the partition plate 20 is installed on the slide rail 15, the second end of the partition plate 20 is moved to the installation notch 152, and the sliding mating part 22 is slidably sleeved on the slide rail 15 from the installation notch 152.

[0049] An installation notch 152 is provided on the slide rail 15 so that the sliding mating part 22 does not need to be removed from the slide rail 15 by external force to pull and deform it, thus avoiding the failure of the deformed part of the sliding mating part 22 after repeated use. The sliding mating part 22 can be installed on the slide rail 15 through the installation notch 152.

[0050] In some embodiments, the mounting notch 152 is provided in the middle of the slide rail 15 or at both ends of the slide rail 15.

[0051] Please refer to some embodiments of this utility model. Figure 9 and Figure 10 The sliding engagement portion 22 includes a main body portion 223, a first sliding portion 221, and a second sliding portion 222. The first sliding portion 221 and the second sliding portion 222 are respectively connected to opposite sides of the main body portion 223. The first sliding portion 221 and the second sliding portion 222 are slidably disposed on opposite sides of the slide rail 15 in the width direction. The first sliding portion 221 and the second sliding portion 222 are spaced apart from each other, so that the first sliding portion 221, the second sliding portion 222, and the main body portion 223 form an embedding groove. When the sliding engagement portion 22 is installed on the slide rail 15, the slide rail 15 is engaged in the embedding groove. The two sides of the slide rail 15 in the width direction are the two sides of the slide rail 15 in the first direction.

[0052] By providing the first sliding part 221 and the second sliding part 222, the sliding engagement part 22 can slide and engage with both sides of the slide rail 15 in the width direction.

[0053] When the sliding engagement 22 is detachably engaged with the slide rail 15, at least one of the first sliding part 221 and the second sliding part 222 can be deformed under force, so that the sliding engagement 22 can be removed from the slide rail 15.

[0054] Please refer to some embodiments of this utility model. Figure 10A locking structure is provided on the first sliding part 221 to lock the first sliding part 221 to the slide rail 15 and prevent the sliding mating part 22 from sliding. For other embodiments, please refer to... Figure 9 No locking structure is provided on the first sliding part 221 and the second sliding part 222. When the first end of the partition plate 20 can move freely, the sliding mating part 22 can also slide freely on the slide rail 15.

[0055] Please refer to some embodiments of this utility model. Figure 10 The sliding mating part 22 also includes the aforementioned locking structure, which includes a pressing member 225, a pin 224, and an elastic member. A positioning hole is provided on the shelf 10. The pin 224 is slidably disposed on the first sliding part 221. The pressing member 225 is used to insert the pin 224 into the positioning hole, and the elastic member is used to return the pin 224 to its original position, disengaging it from the positioning hole. When it is necessary to fix the partition plate 20, the pressing member 225 is pressed down, the elastic member is compressed, and the pin 224 is inserted into the positioning hole, locking the partition plate 20 and the shelf 10 together. When it is necessary to adjust the position of the partition plate 20, the pressing member 225 is pressed down again, causing the pin 224 to disengage from the shelf 10. Under the rebound action of the elastic member, the pin 224 returns to its original position, disengaging it from the positioning hole. Of course, the above is only an example of a locking structure; other forms of locking structures are also applicable to this utility model.

[0056] This utility model also provides a freezer, which includes the freezer shelf structure of any of the above embodiments. The freezer may also include a cabinet, a freezer door, and other structures, and the freezer shelf structure is generally installed inside the cabinet.

[0057] The freezer provided by this utility model adopts the aforementioned freezer shelf structure. The freezer shelf structure includes a shelf 10 and a partition plate 20 disposed on the shelf 10. The insertion part 21 at the first end of the partition plate 20 is inserted into the slot unit 141 of the shelf 10, and the second end of the partition plate 20 is slidably connected to the slide rail 15 of the shelf 10. When it is necessary to adjust the position of the partition plate 20, the partition plate 20 can be deformed or the sliding mating part 22 can be removed from the slide rail 15, the insertion part 21 can be removed from the slot unit 141, and then the partition plate 20 can be moved to the corresponding position. Finally, the partition plate 20 is installed to realize the adjustment of the position of the partition plate 20. The shelf 10 and partition plate 20 used in this utility model do not require disassembly and assembly tools when adjusting the position of the partition plate 20, which can improve the adjustment efficiency of the partition plate 20 position.

[0058] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
