[0036] Please combine Figure 1 as well as Figure 2 As shown, the present application first provides a door structure, including a door panel main body 10 and a cabinet panel 20; the door panel main body 10 is provided with a plurality of connecting holes 11, and a plurality of connecting members 30 corresponding to the connecting holes 11 are fixed on the cabinet panel 20, and each connecting member 30 is clamped with the corresponding connecting hole 11, so that the connecting member 30 is against the inner wall of the connecting hole 11 downward in the vertical direction, and there is a gap with the inner wall of the connecting hole 11 in other directions; screw holes 12 are also through-opened on the door panel main body 10, and the door panel main body 10 and the cabinet panel 20 are fixed by screws passing through the screw holes 12.

[0037] In the present application, the initial positioning between the door panel body 10 and the cabinet panel 20 can be completed by inserting the connecting piece 30 into the corresponding connecting hole 11 to complete the snap-fitting. At this time, there is a gap between the connecting piece 30 and the inner wall of the connecting hole 11 in all directions except vertically downward. The gap can be used to absorb the position deviation of the connecting piece 30 and the connecting hole 11. By fine-tuning the position of the cabinet panel 20 relative to the door panel body 10, it can be ensured that the cabinet panel 20 is flush with the side of the door panel body 10. After the alignment is completed, the door panel body 10 and the cabinet panel 20 can be fixed by screws and screw holes 12, which effectively reduces the accuracy requirements on the connection structure between the cabinet panel 20 and the door panel body 10, and also reduces the installation difficulty between the two.

[0038] In addition, since the cabinet panel 20 and the door panel body 10 are relatively fixed after installation, there will be no relative movement between the two, and abnormal noise or aging caused by friction is prevented from occurring.

[0039] It is not difficult to understand that, through the initial limiting between the connecting member 30 and the connecting hole 11, the connecting member 30 is against the inner wall of the connecting hole 11 in the vertical direction. At this time, the door panel main body 10 supports the cabinet panel 20 through the connecting member 30, which reduces the burden on the operator and reduces the difficulty of subsequent fine-tuning the position of the cabinet panel 20 and fixing the two. In addition, due to the limiting effect of the connecting hole 11, the connecting member 30 can only move inside the connecting hole 11, which also avoids the situation where the cabinet panel 20 is adjusted too much, that is, by limiting the range of movement of the cabinet panel 20, the difficulty of subsequent fine-tuning and fixing is further reduced.

[0040] In some other embodiments, after fine-tuning the cabinet panel 20 so that the cabinet panel 20 is flush with the side of the door panel body 10, other commonly used fixing methods other than screw fixing can also be used to complete the fixation between the cabinet panel 20 and the door panel body 10, such as bonding, etc., which are not listed one by one in this application.

[0041] Please combine Figure 3 , Figure 4 as well as Figure 5 As shown, in some embodiments, the door panel body 10 has a hollow cavity 13 inside, and each connecting hole 11 penetrates the side wall of the door panel body 10 inward to communicate with the hollow cavity 13, and each connecting hole 11 includes a mounting hole 111 and a limiting hole 112 that are connected to each other, and the mounting hole 111 is located on the upper side of the limiting hole 112; each connecting member 30 includes a limiting shaft 31 and a supporting shaft 32 fixed along the axial direction, and the support shaft 32 is located on the side close to the cabinet panel 20; the diameter of the limiting shaft 31 is smaller than the mounting hole 111 and larger than the limiting hole 112, the diameter of the support shaft 32 is smaller than the limiting hole 112, and the support shaft 32 is against the inner wall of the limiting hole 112 in the vertical direction, and the projection of the limiting shaft 31 along its own axial direction at least partially intersects with the inner wall of the hollow cavity 13.

[0042] Since the diameter of the limiting shaft 31 is smaller than the mounting hole 111, the limiting shaft 31 can pass through the mounting hole 111 and be inserted into the hollow cavity 13;

[0043] Since the diameter of the support shaft 32 is smaller than the size of the connecting position between the mounting hole 111 and the limiting hole 112, and the diameter of the support shaft 32 is also smaller than the diameter of the limiting hole 112, after the limiting shaft 31 is inserted into the hollow cavity 13, the support shaft 32 can be inserted downward into the limiting hole 112, so that the support shaft 32 is vertically downward against the inner wall of the limiting hole 112, and the door panel body 10 supports the cabinet board 20 through the connecting member 30;

[0044] Finally, since the diameter of the limiting shaft 31 is larger than the diameter of the limiting hole 112, and the projection of the limiting shaft 31 along its own axial direction at least partially intersects with the inner wall of the hollow cavity 13, the inner wall of the hollow cavity 13 can prevent the limiting shaft 31 from moving outward and prevent the limiting shaft 31 from leaving the hollow cavity 13, thereby playing a preliminary limiting role.

[0045] Of course, in some other embodiments, the limiting shaft 31 and the support shaft 32 may also be prisms or other shapes, and the mounting hole 111 and the limiting hole 112 may also be directions or other shapes, as long as the support shaft 32 can be inserted into the hollow cavity 13 through the mounting hole 111, the support shaft 32 can be inserted into the limiting hole 112, and the limiting shaft 31 can be blocked by the inner wall of the hollow cavity 13 along the axial direction.

[0046] Please combine Figure 3 as well as Figure 5As shown, in some embodiments, the diameter of the limiting hole 112 is more than 1 mm larger than the diameter of the support shaft 32, and the gap between the two is used to absorb the position deviation of the connecting piece 30 and the connecting hole 11 to ensure that the cabinet panel 20 can be fine-tuned to be flush with the side of the door panel body 10.

[0047] Please combine Figure 3 , Figure 4 as well as Figure 5 As shown, in some embodiments, a plurality of installation boxes 40 corresponding to the connection holes 11 are fixed to the inner wall of the hollow cavity 13, and the installation box 40 is provided with an installation cavity 41 facing the corresponding connection hole 11; when the support shaft 32 abuts against the inner wall of the limiting hole 112, the limiting shaft 31 abuts against the lower inner wall of the installation cavity 41.

[0048] The limiting shaft 31 abuts against the lower inner wall of the installation cavity 41 to increase the contact area between the connecting member 30 and the door panel body 10 in the vertical direction, thereby preventing the connecting member 30 or the inner wall of the limiting hole 112 from deforming due to excessive local pressure.

[0049] Please refer to Figure 4 As shown, in some embodiments, the outer peripheral surface of the limiting shaft 31 has a planar portion 311. When the support shaft 32 abuts against the inner wall of the limiting hole 112, the planar portion 311 abuts against the lower inner wall of the mounting cavity 41. The planar portion 311 can, on the one hand, further increase the contact area between the connecting piece 30 and the door panel body 10 along the vertical direction, and on the other hand, can also increase the clamping stability between the connecting piece 30 and the door panel body 10, so as to facilitate the subsequent fine-tuning of the cabinet panel 20.

[0050] Please combine Figure 4 as well as Figure 5 As shown, in some embodiments, the installation box 40 is also fixed with a baffle 42 located between the limiting shaft 31 and the cabinet panel 20, and the limiting shaft 31 is against the baffle 42 along its own axial direction; the baffle 42 can strengthen the structural strength of the door panel body 10, and prevent the door panel body 10 around the limiting hole 112 from deforming outward under the pulling force of the limiting shaft 31, so as to improve the installation reliability of the door body structure of the present application.

[0051] Please combine Figure 4 as well as Figure 5 As shown, in some embodiments, the connecting member 30 can be detachably fixed to the cabinet panel 20; specifically, the connecting member 30 can be set on the cabinet panel 20 by commonly used fixing methods such as bonding and screw connection, so that the door panel body 10 in the present application can be connected to any cabinet panel 20, as long as the connecting member 30 is fixed on the cabinet panel 20 before the connection and installation, which effectively improves the versatility of the door body structure of the present application.

[0052] Preferably, the connecting member 30 is fixed to the cabinet board 20 by screws penetrating through the connecting member 30 .

[0053] Please refer to Figure 2 As shown, in some embodiments, at least four connection holes 11 are opened on the door panel body 10, wherein at least two connection holes 11 are symmetrically opened with the vertical center line of the door panel body 10 as the center, and at least two connection holes 11 are symmetrically opened with the horizontal center line of the door panel body 10 as the center.

[0054] In this way, two connection holes 11 symmetrically opened around the transverse center line of the door panel body 10 can be used to preliminarily position the cabinet board 20, and at least four connection holes 11 can ensure that the cabinet board 20 and the door panel body 10 will not shake after completing the preliminary positioning.

[0055] Preferably, at least eight connection holes 11 are formed on the door panel body 10 , and four connection holes 11 are further formed near the four corners of the door panel body 10 .

[0056] Please combine Figure 6 as well as Figure 7 As shown, in some embodiments, a screw nut 121 is embedded in one end of the screw hole 12 away from the cabinet panel 20, and the screw nut 121 is used to cover the screw hole 12 to prevent the screw hole 12 from being directly exposed to the inner side of the door panel body 10, thereby increasing the service life of the screw at this position and improving the aesthetics.

[0057] Preferably, a snap-in groove is provided inside the screw hole 12, and the snap-in portion on the top of the screw cap 121 can snap-in with the snap-in groove.

[0058] A second aspect of the present application provides a built-in refrigerator, comprising a refrigerator body and the above-mentioned door body structure, wherein a door panel body 10 is hinged to the refrigerator body.

[0059] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described 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 above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
