[0043] At present, the process from the factory to the user's home involves the transportation of the refrigerator, which often causes some fasteners of the refrigerator to loosen during transportation. Due to the large mass of the door body and many movable factors, excessive bumps during transportation will cause the door body to tilt.

[0044] In the related art, in order to eliminate the problem caused by the misalignment of the door body, a hinge structure of a refrigerator door body and a refrigerator are provided. The refrigerator includes an upper door body and a lower door body located below the upper door body. The hinge structure includes: a support member connected to the housing of the refrigerator and arranged between the upper door body and the lower door body; a hinge shaft arranged vertically, the hinge shaft includes an upper shaft body, a middle shaft body and a lower shaft body, the upper shaft body abuts against the bottom of the upper door body, the middle shaft body is threadedly connected to the support member, and the lower shaft body is located below the support member; a transmission mechanism includes a first bevel gear and a second bevel gear meshed with the first bevel gear, the first bevel gear is connected to the lower shaft body and can drive the lower shaft body to rotate. The hinge structure in the related art is complex, costly, and difficult to repair.

[0045] The disclosed embodiment utilizes hinges to connect the refrigerator door and cabinet 12, and installs an adjustment component between the hinge and the door. The position of the door relative to the hinge is adjusted by the adjustment component to indirectly adjust the position of the door relative to the cabinet 12, so as to adjust the fit between the door and cabinet 12.

[0046] Combination Figures 1 to 8The embodiment of the present disclosure provides an adjustment structure of a door body 11 of a refrigerator 10. The refrigerator 10 includes a door body 11 and a box body 12, and the door body 11 is installed on the box body 12. The adjustment structure of the door body 11 of the refrigerator 10 includes an adjustment component 13, a first hinge 14, and a second hinge 15. The adjustment component 13 is symmetrically arranged at a first end 111 of the door body and a second end 113 of the door body opposite to the first end 111 of the door body; the first hinge 14 connects the adjustment component 13 at the first end 111 of the door body and the box body 12 of the refrigerator 10; the second hinge 15 connects the adjustment component 13 at the second end 113 of the door body and the box body 12 of the refrigerator 10; wherein, the position of the door body 11 relative to the box body 12 can be adjusted by the adjustment component 13.

[0047] like Figures 1 to 3 As shown, a box opening 101 is provided on the side of the refrigerator 10, and a door body 11 is covered on the box opening 101. The first end 111 of the door body is connected to the box body 12 through an adjustment component 13 and a first hinge 14; the second end 113 of the door body is connected to the second hinge 15 through an adjustment component 13. Among them, the first end 111 of the door body is first connected to the adjustment component 13, and is connected to one end of the first hinge 14 through the adjustment component 13, and the other two ends of the first hinge 14 are connected to the box body 12. The adjustment component 13 can adjust the position of the door body 11 relative to the box body 12 in the direction from the first end 111 of the door body to the second end 113 of the door body. To adjust the position of the door body 11 relative to the box body 12.

[0048] like Figure 1 As shown, in some embodiments, when the refrigerator 10 is vertically erected, the box opening 101 faces forward, the first end 111 of the door body is the upper end of the door body 11, and the second end 113 of the door body is the lower end of the door body 11.

[0049] Optionally, the adjustment component 13 includes a first gear 131 and a second gear 132. The first gear 131 is rotatably connected to the door body 11; the second gear 132 is meshed with the first gear 131; at the first end 111 of the door body, one end face of the second gear 132 is rotatably connected to the first hinge 14, and the other end face of the second gear 132 is connected to the door body 11 by an adjustable thread; at the second end 113 of the door body, one end face of the second gear 132 is rotatably connected to the second hinge 15, and the other end face of the second gear 132 is connected to the door body 11 by an adjustable thread; by adjusting the thread connection depth of the first end 111 of the door body, the position of the door body 11 relative to the second gear 132 is changed to change the position of the door body 11 relative to the first hinge 14 and then change the position of the door body 11 relative to the box body 12.

[0050] like Figures 4 to 6As shown, the axis of the second gear 132 at the first end 111 of the door body and the axis of the second gear 132 at the second end 113 of the door body are located in the same straight line. At the first end 111 of the door body, the second gear 132 is threadedly connected to the door body 11, and the second gear 132 can change the distance between the door body 11 and the first hinge 14 by the length of the threaded connection. The rotation of the first gear 131 can drive the second gear 132 to rotate and thereby change the threaded connection depth between the second gear 132 and the door body 11. In the process of reducing the threaded connection length between the second gear 132 and the door body 11, the second gear 132 drives the door body 11 to move in the direction from the second end 113 of the door body to the first end 111 of the door body. Since the door body 11 is fixedly connected to the second hinge 15 and the box body 12 at the second end 113 of the door body, when the door body 11 is skewed, the first end 111 of the door body rotates around the second end to adjust the door body 11. Figure 5 In the case where the first gear 131 is rotated to drive the second gear 132 to rotate and unscrew the threaded connection, the second gear 132 drives the first hinge 14 to move in the direction of arrow A1, and the second end 113 of the door body is fixed by the second gear 132 and the second hinge 15. The door body 11 is subjected to the force in the direction of A1. At this time, the door body 11 tilted to the left rotates in the direction of A2 around the axis of the second gear 132 at the second end 113 of the door body and the fixing point of the second hinge 15 under the action of the right component of the traction force in the direction of A1. When the door body 11 is tilted to the right, the first gear 131 at the first end 111 of the door body is rotated to drive the second gear 132 to rotate and screw into the threaded connection, that is, the second gear 132 moves toward the direction of A3 to make the first hinge 14 close to the door body 11. At this time, the first end 111 of the door body is subjected to pressure in the direction of A3. When the second end 113 of the door body is fixed by the adjustment assembly 13 and the second hinge 15, the door body 11 is subjected to the left component force of A3 and rotates around the center of the connection between the second end 113 of the door body and the second hinge 15 along the arrow A4 to adjust the door body 11. When the door body 11 is misaligned in the direction of A1 as a whole, the first gear 131 of the first end 111 of the door body is rotated to drive the second gear 132 to rotate and the first gear 131 of the second end 113 of the door body is rotated to drive the second gear 132 to rotate, and the adjustment assembly 13 of the first end 111 of the door body and the second end 113 of the door body work together to move the door body 11 in the direction of A3 to adjust the misalignment. Similarly, when the door body 11 is misaligned in the direction of A4 as a whole, the adjustment assembly 13 of the first end 111 of the door body and the adjustment assembly 13 of the second end 113 of the door body are adjusted at the same time to move the door body 11 in the direction of A3 to adjust the misalignment.

[0051] Optionally, the first gear 131 is connected to the door body 11 through a first hole shaft 133; the second gear 132 is connected to the door body 11 through a threaded joint 134; rotating the first gear 131 drives the second gear 132 to rotate to adjust the threaded connection depth to adjust the position of the door body 11 relative to the box body 12.

[0052] like Figure 5 and Figure 6 As shown in the figure, the first gear 131 at the first end 111 of the door body and the second end 113 of the door body are both hole-axis matched with the door body 11, and the hole-axis matching surface is a smooth contact surface so that the first gear 131 can easily rotate relative to the door body 11, so that when the first gear 131 is rotated to adjust the second gear 132, more energy will not be wasted due to the overly tight matching of the hole-axis between the first gear 131 and the door body 11, so as to facilitate operation. The second gear 132 at the first end 111 of the door body is connected to the door body 11 by a threaded fit 134. The threaded fit 134 connection has strong connectivity and is not easy to loosen. Since the door body 11 is buckled on the box opening 101 and the side panel of the door body 11 is tightly fitted with the box opening 101, the inclination of the door body 11 is mainly divided into the inclination of the left and right sides along the sliding surface of the box opening 101. When the door body 11 and the second gear 132 are connected by threads, when no adjustment is required, the second gear 132 is subjected to the inclination force in the left and right directions, which will not cause the second gear 132 to rotate, so it can have better stability. When it is necessary to adjust the inclination of the door body 11, the first gear 131 is rotated to drive the second gear 132 to rotate. After the adjustment is completed, it is not necessary to lock it. The thread will not be actively loosened, and the operation is simple.

[0053] In some embodiments, the threaded connection 134 between the second gear 132 and the door body 11 uses a self-locking thread.

[0054] Optionally, the first hole axis 133 is fitted with a clearance fit.

[0055] The first hole shaft 133 is matched with the first gear 131 and the door body 11, and is mainly used to install the first gear 131. The first gear 131 is used to rotate to drive the rotation of the second gear 132. Therefore, the first gear 131 needs to rotate without obstruction to reduce the difficulty of operation during the adjustment process. The clearance fit can reduce the rotational friction between the first hole shaft 133 during the rotation of the first gear 131.

[0056] Optionally, the first hinge 14 is connected to the corresponding second gear 132 through the second hole shaft 16 ; the second hinge 15 is connected to the corresponding second gear 132 through the third hole shaft 17 .

[0057] like Figure 5 and Figure 6 As shown, the first hinge 14 and the second hinge 15 are connected to the second gear 132 through a hole-shaft fit. The second hole-shaft 16 is the fit between the first hinge 14 and the second gear 132 at the first end 111 of the door body. The third hole-shaft 17 is the fit between the second hinge 15 and the second gear 132 at the second end 113 of the door body.

[0058] Optionally, the second hole-shaft 16 is connected by a tapered shaft and a tapered hole.

[0059] like Figure 5 As shown, the second hole axis 16 is a connection method between the second gear 132 at the first end 111 of the door body and the first hinge 14. The connection between the second gear 132 at the first end 111 of the door body and the first hinge 14 becomes loose due to the skewness of the door body 11 or the increase in the use time. At this time, it is necessary to pre-tighten the connection between the first hinge 14 and the second gear 132. The second hole axis 16 is configured to be connected with the cone axis and the cone hole, and the cone can be inserted deeper into the cone hole by increasing the matching length of the cone and the cone hole to increase the connection tightness between the first hinge 14 and the second gear 132.

[0060] Optionally, the third hole-shaft 17 is matched into a cylindrical hole-shaft matching structure or a conical hole-shaft matching structure.

[0061] like Figure 6 As shown, since the adjustment assembly 13 at the second end 113 of the door body is mainly used to fix the second end 113 of the door body, a stable connection is required. The cylindrical hole-shaft matching structure is not easy to loosen when the cylinder and the hole are tightly matched, and can maintain long-term usability. At the same time, the third hole-shaft 17 is matched with a cone hole-shaft matching structure, which can be similar to the connection structure of the second gear 132 and the first hinge 14 at the first end 111 of the door body. In the case of loose connection, the second hinge 15 and the second gear 132 can be pre-tightened by increasing the connection length of the cone hole-shaft.

[0062] Optionally, a mounting groove 112 is provided at the first end 111 of the door body, and the adjusting assembly 13 is installed on the bottom wall 1121 of the mounting groove 112; the second gear 132 is provided with an axial hole 161; the first hinge 14 is provided with an extending shaft 162 adapted to the axial hole 161; wherein the extending shaft 162 extends from the first hinge 14 toward the axial hole 161 and is inserted into the interior of the axial hole 161 to connect the first hinge 14 and the second gear 132, so that there is an adjustment gap between the first hinge 14 and the second gear 132.

[0063] like Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, the mounting groove 112 of the door body 11 is arranged at the corresponding position of the door body 11 and the edge of the box opening 101, so that the box opening 101 is blocked from communicating with the mounting groove 112 during the adjustment of the door body 11 to prevent the cold air from flowing out. The bottom wall 1121 of the mounting groove 112 is lower than the upper end of the box body 12 in the vertical direction, one end of the first hinge 14 is connected to the upper end surface of the box body 12, and the other end of the first hinge 14 is connected to the second gear 132, and the second gear 132 is installed on the bottom wall 1121. The first hinge 14 is provided with a protruding shaft 162 corresponding to the second gear 132, and the second gear 132 is provided with an axis hole 161 along the axis, the axis hole 161 is a cone hole, and the protruding shaft 162 is a cone axis, and is adapted in the axis hole 161. The first hinge 14 and the second gear 132 are connected by an extended shaft 162. When the first hinge 14 and the second gear 132 are connected, the axial length of the extended shaft 162 is such that there is a certain gap between the first hinge 14 and the second gear 132, so that when the hole-shaft connection is loose, the conical shaft can be embedded more deeply into the conical hole to increase the tightness of the connection between the first hinge 14 and the second gear 132.

[0064] Combination Figures 1 to 8 The embodiment of the present disclosure provides a refrigerator 10, comprising a box body 12, a door body 11, and an adjustment structure of the door body 11 of the refrigerator 10 as in any of the above embodiments. The box body 12 is provided with a box opening 101; the door body 11 is installed at the box opening 101; and the adjustment structure of the door body 11 of the refrigerator 10 is used to adjust the relative position of the door body 11 and the box body 12.

[0065] like Figures 1 to 8 As shown, the refrigerator 10 includes a box body 12, the box body 12 defines a storage space, the box body 12 is provided with a box opening 101, and the door body 11 is buckled at the box opening 101 to block the box opening 101 to prevent cold air from flowing out. The first end 111 of the door body is connected to the box body 12 through a first hinge 14 and an adjustment component 13. The second end 113 of the door body is connected to the box body 12 through a second hinge 15 and the adjustment component 13.

[0066] The refrigerator 10 provided in the embodiment of the present disclosure includes the door body 11 adjustment structure of the refrigerator 10 as in any one of the above embodiments, and therefore has all the benefits of the door body 11 adjustment structure of the refrigerator 10 as in any one of the above embodiments, which will not be repeated again.

[0067] like Figure 7 As shown, in some embodiments, the refrigerator 10 is a double-door refrigerator 10, including door bodies 11 that open and close relative to each other, wherein the upper end of each door body 11 is connected to the box body 12 through a first hinge 14 and an adjustment assembly 13; and the lower end of each door body 11 is connected to the box body 12 through a second hinge 15 and an adjustment assembly 13.

[0068] Optionally, both ends of the door body 11 protrude from the edges of the corresponding box opening 101, and the protruding dimensions are greater than the maximum adjustment dimension of the door body 11, so that the door body 11 can always cover the box opening 101 during the adjustment and movement process to prevent cold air from flowing out.

[0069] like Figure 2 and Figure 3 As shown, for each door body 11, both ends of the door body 11 along the direction from the first end 111 of the door body to the second end 113 of the door body protrude outside the box opening 101, as shown in FIG. Figure 2 The middle length H is the length of the first end 111 of the door body above the box body 12; Figure 3 The middle length L is the length of the second end 113 of the door body protruding from the box opening 101, wherein H and L are both larger than the adjustment size of the door body 11, so that the door body 11 can still cover the box opening 101 during the adjustment process to prevent cold air from flowing out.
