Therefore, in order to avoid cold air leakage, the refrigerator needs a door body with better sealing. For example, Chinese patent number CN220036410U discloses a refrigerator door body installation structure, including a refrigerator side panel, a refrigerator door body, a side panel connector, a door body connector and a connecting shaft; the side panel connector includes a side panel groove-type connecting part and a plurality of side panel positioning sleeves; the refrigerator side panel is placed in the side panel groove-type connecting part and is fixedly connected to the side panel groove-type connecting part; the door body connector includes a door body groove-type connecting part, a connecting plate part and a plurality of door body positioning sleeves located at the edge of the connecting plate part; the refrigerator door body is located in the door body groove-type connecting part and is fixedly connected to the door body groove-type connecting part; the side panel positioning sleeves and the door body positioning sleeves are staggered and axially aligned, the connecting shaft axially passes through the side panel positioning sleeves and the door body positioning sleeves, and positioning baffles are fixed at both ends of the connecting shaft. Although this prior art enhances the connection strength between the refrigerator door and the refrigerator side panel, the connection structure is complex and inconvenient to install. In addition, multiple connectors easily cause uneven force on the door body and deformation when the door is pulled, resulting in poor sealing. Utility Model Content
[0003] In order to overcome the above-mentioned shortcomings of the prior art, the utility model provides a refrigerator door body and a refrigerator, which can enhance the sealing performance and improve the heat preservation effect.
[0004] The technical solution adopted by the utility model to solve its technical problems is:
[0005] A refrigerator door body, which is hinged to the refrigerator body through an upper door shaft and a lower door shaft, the upper door shaft and the lower door shaft are respectively located at the upper and lower ends of the hinged side of the door body, a middle door shaft is provided between the upper door shaft and the lower door shaft, the middle door shaft is a hollow tube structure fixed to the body; a first plug rod is provided vertically downward at the bottom of the upper door shaft, and a second plug rod is provided vertically upward at the top of the lower door shaft, the first plug rod and the second plug rod are respectively inserted into the hollow tube structure of the middle door shaft, and the outer walls of the first plug rod and the second plug rod match the inner wall of the hollow tube structure.

Among them, the shape of the magnet is consistent with the internal shape of the door liner and the box liner, which is conducive to reducing the distance between the two magnets, thereby increasing the tension of the magnet and enhancing the sealing.
[0012] In a preferred technical solution, the refrigerator door also includes a first door seal and a second door seal arranged on the end surface of the door body, the second door seal is farther away from the interior of the box body relative to the first door seal, and the second door seal is higher than the first door seal, and both the first door seal and the second door seal are soft hollow structures; a convex rib is provided on the end surface of the box body at a position corresponding to the top of the first door seal.
[0013] In this technical solution, when the door body and the box body are closed under the action of magnetic force, that is, the door liner and the box liner are attracted together by the attraction of the magnet, the soft and hollow door seal will be extruded and deformed, thereby achieving a good sealing effect; in addition, the hollow door seal can make the cold conduction speed slower and has a better thermal insulation effect.
[0014] In a preferred technical solution, the tops of the first door seal and the second door seal are both arc-shaped, which are not easy to accumulate dust and are easy to clean and maintain.
[0015] In a preferred technical solution, the height difference between the second door seal and the first door seal is equal to the deformation of the first door seal when the box body and the door body are closed, so that the extrusion deformation of the second door seal when closing the door is large enough, thereby further ensuring the sealing effect.
[0016] In a preferred technical solution, the first door seal and the second door seal are both made of foam rubber, which is soft and highly resilient and can rebound when compressed, thereby achieving a better sealing effect.
[0017] In a preferred technical solution, the cross-sectional size of the convex rib is 1.5 mm×1 mm to ensure that the first door seal is sufficiently deformed, extend the distance of the cold air flow to the outside of the box, and further enhance the sealing.

[0019] It can be seen from the above technical solution that compared with the prior art, the beneficial effects of the utility model are:
[0020] The utility model provides a refrigerator door body, which arranges the upper door axis and the lower door axis at the upper and lower ends of the door body so that the maximum feasible distance between the two positions is maintained, thereby ensuring that the force is evenly distributed when the door body and the box body are sealed, thereby effectively preventing deformation; at the same time, the upper door axis and the lower door axis respectively adopt a structure in which the rod is inserted into the middle door axis to a certain depth, which can prevent the door body from being displaced or deformed in size, which is beneficial to avoiding the poor sealing caused by the above-mentioned situation and can enhance the sealing.

In addition, in the description of the present invention, unless otherwise specified, "plurality" means two or more.
[0032] Reference Figure 1-5 A refrigerator door 100 and a refrigerator according to an embodiment of the present invention are described.
[0033] In one embodiment, Figure 1 As shown, a refrigerator door 100 is hinged to a refrigerator body 200 through an upper door shaft 1 and a lower door shaft 3, the upper door shaft 1 and the lower door shaft 3 are respectively located at the upper and lower ends of the hinged side of the door 100, and a middle door shaft 2 is provided between the upper door shaft 1 and the lower door shaft 3, and the middle door shaft 2 is a hollow tube structure fixed to the body 200. Among them, the upper door shaft 1 and the lower door shaft 3 are located at the upper and lower ends of the door 100, and the maximum distance between the two positions is maintained, which is conducive to uniform force when the door 100 and the body 200 are sealed to prevent deformation.
[0034] Figure 2-3 They are Figure 1 Schematic diagram of the exploded structure of the upper door shaft in area A and the lower door shaft in area B, a first plug rod 11 is provided vertically downward at the bottom of the upper door shaft 1, and a second plug rod 31 is provided vertically upward at the top of the lower door shaft 3, the first plug rod 11 and the second plug rod 31 are respectively inserted into the hollow tube structure of the middle door shaft 2, and the outer walls of the first plug rod 11 and the second plug rod 31 match the inner wall of the hollow tube structure.
[0035] Among them, the depth of the insertion rods of the upper door shaft 1 and the lower door shaft 3 into the middle door shaft 2 can be 10% to 30% of the length of the middle door shaft 2 to ensure stability and better prevent the door body 100 from displacement or dimensional deformation, thereby avoiding poor sealing.
[0036] In this embodiment, if Figure 4 As shown, the door body 100 is provided with magnets 4 at the upper end, middle part and lower end of the opening and closing side, and the box body 200 is also provided with magnets 4 at positions corresponding to the magnets 4 at the upper end, middle part and lower end of the door body 100.
[0037] In specific implementation, the magnets 4 are distributed at the upper, middle and lower positions of the closed side of the door body 100 and the box body 200, which is beneficial for uniform force on the door body 100 when closing the door, and further ensures the sealing when closing the door.
[0038] In this embodiment, the door body 100 includes an internal door body insulation layer 101 and a door liner 102 for wrapping the door body insulation layer 101, and the box body 200 includes an internal box body insulation layer 201 and a box liner 202 for wrapping the box body insulation layer 201; on the side where the door body 100 and the box body 200 open and close, the door liner 102 and the box liner 202 are both U-shaped structures, and the cross section of the U-shaped structure is rectangular. Among them, the U-shaped structure design can ensure the flatness and strength of the sealing plane, thereby achieving a good sealing effect.
[0039] In this embodiment, the magnet 4 in the door body 100 is arranged in the U-shaped structure of the door liner 102, and the magnet 4 in the box body 200 is arranged in the U-shaped structure of the box liner 202; the shape of the magnet 4 in the door body 100 is consistent with the internal shape of the U-shaped structure of the door liner 102, and the shape of the magnet 4 in the box body 200 is consistent with the internal shape of the U-shaped structure of the box liner 202.
[0040] This embodiment uses magnets 4 that are consistent with the internal shapes of the door liner 102 and the box liner 202, which is beneficial for reducing the distance between the two magnets 4, thereby increasing the tensioning force of the magnets 4 and achieving the effect of enhancing the sealing.
[0041] In this embodiment, if Figure 4-5 As can be seen from the C area shown, it also includes a first door seal 5 and a second door seal 6 arranged on the end face of the door body 100. The second door seal 6 is farther away from the interior of the box body 200 relative to the first door seal 5, and the second door seal 6 is higher than the first door seal 5. The first door seal 5 and the second door seal 6 are both soft hollow structures; a convex rib 7 is provided at a position corresponding to the vertex of the first door seal 5 on the end face of the box body 200.
[0042] The height of the convex rib 7 can be set to be no less than 1.5 mm. Under the suction of the magnet 4, when the convex rib 7 presses against the top of the first door seal 5, the first door seal 5 is transformed into a convex rib 7 wall that is close to the end surface of the box body 200, which prolongs the distance of the cold air flow to the outside, enhances the sealing performance, and thus achieves a better insulation effect.
[0043] In the present technical solution, when the door body 100 and the box body 200 are closed under the action of magnetic force, that is, the door liner 102 and the box liner 202 are attracted together by the attraction of the magnet 4, the soft and hollow door seal will be squeezed and deformed, thereby achieving a good sealing effect; in addition, the hollow door seal can make the cold conduction speed slower and has a better thermal insulation effect.
[0044] In specific implementation, when the box body 200 and the door body 100 are attracted by the magnet 4, the convex rib 7 is pressed into the top of the first door seal 5 to deform the first door seal 5. At the same time, under the suction of the magnet 4, the end face of the box body 200 also squeezes the first door seal 5 and the second door seal 6, so that both layers of door seals are in close contact with the end face of the box body 200, thereby achieving a double-layer insulation effect. Among them, the second door seal 6 is higher than the first door seal 5, so that when the box body 200 presses the two layers of door seals, the second door seal 6 is more closely attached to the end face of the box body 200, which is conducive to enhancing the sealing performance.
[0045] In this embodiment, the tops of the first door seal 5 and the second door seal 6 are both arc-shaped, which is not easy to accumulate dust and is easy to clean and maintain.
[0046] In this embodiment, the height difference between the second door seal 6 and the first door seal 5 is equal to the deformation of the first door seal 5 when the box body 200 and the door body 100 are closed. The deformation of the first door seal 5 when the box body 200 and the door body 100 are closed is the deformation of the first door seal 5 caused by the compression of the box body 200 and the door body 100 when they are closed under the attraction of the magnet 4.
[0047] In this embodiment, the first door seal 5 and the second door seal 6 are both made of foam rubber.
[0048] In the above embodiment, since the foam rubber material has the advantages of being soft and having strong resilience, it is easy to rebound after being compressed, which can further ensure the sealing of the refrigerator.
[0049] In this embodiment, the cross-sectional dimensions of the convex rib 7 are 1.5 mm×1 mm, which is used to ensure that the first door seal 5 undergoes sufficient deformation and is easy to manufacture.
[0050] In another embodiment, the utility model provides a refrigerator, which includes the refrigerator door 100 as in any of the above embodiments.
[0051] The refrigerator in this embodiment adopts the above-mentioned refrigerator door body 100 to ensure that the force is evenly applied when the door body 100 and the box body 200 are sealed, thereby preventing the door body 100 from displacement or dimensional deformation, which is beneficial to avoid the poor sealing caused by the above-mentioned situation and enhance the sealing of the product.
[0052] The refrigerator door 100 and other structures and operations of the refrigerator according to the embodiment of the present invention are known to those skilled in the art and will not be described in detail herein.
