[0062] In some embodiments of the present application, as shown in the second and third embodiments, the side end of the first door body 1 is the top end and / or the bottom end thereof, i.e. the end of the first door body 1 in the height direction. In other embodiments, as shown in the first embodiment, the side end of the first door body 1 not only includes the top end and / or the bottom end thereof, but also includes the end thereof in the lateral direction, i.e. in this embodiment, the fixing structure 31 has two locking parts 311 connected to different sides of the first door body 1 to achieve more stable connection. The two locking parts 311 include a first locking part 3112 and a second locking part 3113, and the first locking part 3112 and the second locking part 3113 are arranged on different sides of the first assembly 3. The first locking part 3112 is connected to the top end or the bottom end of the first door body 1, and the second locking part 3113 is connected to the side end of the first door body 1, i.e. the end thereof in the lateral direction, thereby increasing the bonding strength between the first assembly 3 and the first door body 1.

[0063] The first assembly 3 comprises a base plate part 33 and the locking part 311 for fixedly connecting to the first door body 1, and the locking part 311 is bent and extended from the base plate part 33 to lap over the outside of the first door body 1. In an embodiment, the locking part 311 and the first matching portion 32 are arranged on both sides of the base plate part 33 in the up-down direction.

[0064] Further, in the first embodiment of the present application, the fixing structure 31 further comprises a positioning protrusion 312 protruding along the thickness direction of the base plate portion 33 of the first assembly 3 and connected to the front surface of the first door body 1. The first matching portion 32 is arranged on the base plate portion 33, and the locking portion 311 is bent from the base plate portion 33.

[0065] Specifically, as shown in FIGS. 4-8, in the first embodiment of the present application, the first matching portion 32 is provided with a sliding channel 321 and an operation opening 322 for separating operation of the pre-positioning portion 42, the operation opening 322 being in communication with the sliding channel 321.

[0066] In an embodiment, the first matching portion 32 has a first baffle 323 and a second baffle 324 arranged along the thickness direction thereof, the first baffle 323 extending along the sliding matching direction, and the second baffle 324 extending along the up-down direction and located on one side of the operation opening 322 in the sliding matching direction. The first baffle 323 and the second baffle 324 form the sliding channel 321 in the thickness direction of the second matching portion 32, and the second assembly 4 is arranged in the sliding channel 321 and can be slidingly matched therewith. In an embodiment, the second matching portion 41 is arranged in the sliding channel 321 and can be slidingly matched therewith.

[0067] In an embodiment, the first assembly 3 has the first matching portion 32 formed with the sliding channel 321, and a positioning portion 35 connected to the first matching portion 32, the positioning portion 35 being provided with a positioning structure 351 for positioning matching with the pre-positioning portion 42, and the second matching portion 32 and the positioning portion 35 are both arranged on the base plate portion 33.

[0068] In an embodiment, the positioning portion 35 is provided with a pair of the positioning protrusions 312 arranged along the up-down direction. The pair of the positioning protrusions 312 are arranged on both sides of the positioning structure 351 in the up-down direction; in other embodiments, the positioning portion 35 can also have only one positioning protrusion 312 arranged adjacent to the operation opening 322, i.e., it is located between the positioning structure 351 and the operation opening 322 in the sliding matching direction.

[0069] The first fitting part 32 is open at least one end in the direction of sliding fitting with the second component 4, and in the thickness direction of the first component 3, the first fitting part 32 is provided with an operation port 322 for separating operation of the positioning part 42, and the operation port 322 is communicated with the sliding channel 321. In this way, the structure of the connecting device is simple and low in cost, and the traditional manual measurement step is omitted, thereby realizing the sliding connection between the first door body 1 and the second door body 2, and effectively reducing the installation steps and improving the installation efficiency; and the connecting device is hidden between the first door body 1 and the second door body 2, and is not exposed outward during the opening and closing process of the door body, thereby making the whole embedded refrigerator more beautiful.

[0070] In some embodiments, the thickness direction of the first component 3 is the first direction, which is the same as the thickness direction of the first door body 1, and the sliding fitting direction of the second component 4 with the first component 3 is the second direction, which is perpendicular to the first direction, and in the process of opening and closing the door body, the second component 4 can slide relative to the first component 3 along the second direction.

[0071] When the door body of the embedded refrigerator is in the closed state, the sliding direction of the second component 4 is parallel to the transverse direction, and the thickness direction of the first component 3 and the thickness direction of the second component 4 are both perpendicular to the sliding direction of the second component 4, and in this state, the thickness direction of the first component 3 is the front-rear direction.

[0072] The second component 4 is inserted into the first baffle 323 and the second baffle 324 from one end of the positioning part 35 of the second fitting part 32, and then is slidably accommodated in the sliding channel 321. In an embodiment, the second fitting part 41 is inserted into the first baffle 323 and the second baffle 324 from one end adjacent to the positioning protrusion 312 of the sliding channel 321, and then is slidably accommodated in the sliding channel 321.

[0073] In some embodiments, the second baffle 324 is spaced apart between one end away from the operation port 322 and one end away from the positioning part 35 of the second fitting part 32, that is, the second baffle 324 is not arranged on the end edge of the second fitting part 32, so that the end part of the first baffle 323 protruding from the second baffle 324 is used to guide and limit the second component 4.

[0074] The second fitting part 41 is provided with a connecting end surface 410 at one end thereof along the sliding fitting direction, which is used to detachably connect with the pre-positioning part 42. In an embodiment, the second fitting part 41 is provided with a connecting end surface 410 at one end thereof along the sliding fitting direction, which is detachably connected with the second pre-positioning part 422. The installer separates the second fitting part 41 and the second pre-positioning part 422 from the connecting end surface 410, which is exposed outward from the operation port 322.

The first combining part 3511 is used to limit the pre-positioning part 42, and the second combining part 3512 is used to buckle the pre-positioning part 42. The first and the second combining part 3511, 3512 are through grooves formed through the thickness direction of the base plate part 33. The first and the second combining part 3511, 3512 are located between a pair of the positioning protrusions 312 in the up-down direction.

[0078] The second pre-positioning part 422 is provided with a protruding column 4223 and a buckling part 4224 used to cooperate with the first assembly 3. The protruding column 4223 cooperates with the first combining part 3511, and the buckling part 4224 cooperates with the second combining part 3512. The protruding column 4223 is inserted into the first combining part 3211 to preliminarily limit the second assembly 4 and the first assembly 3, and the buckling part 4224 is inserted into the second combining part 3212 to further buckle the second pre-positioning part 422 and the first assembly 3.
