As shown in fig. 1 to 3, in one embodiment, a door body adjusting apparatus is provided, which can be applied to a refrigerator 10 as shown in fig. 1 and 2.

As shown in fig. 2 and 3, the door body adjusting device includes a door body 11, a screw adjuster 13, a cushion 14, and an abutment 15. The side surface of the door body 11 opposite to the refrigerator body 12 is provided with a receiving space 111, and the receiving space 111 is provided with an internal thread matched with the thread adjusting piece 13. The abutting member 15 is provided with a through hole 151, one end of the screw adjusting member 13 passes through the through hole 151 and is screwed into the accommodating space 111, and the other end of the screw adjusting member 13 is limited in the through hole 151. The cushion piece 14 is sleeved outside the threaded adjusting piece 13, and the cushion piece 14 is pressed between the door body 11 and the abutting piece 15.

After the threaded adjusting member 13 is screwed into the receiving space 111 through the abutting member 15 and the cushion member 14 in sequence, the installation process is completed. During use, the penetrating hole 151 directly acts on the threaded adjusting piece 13, the depth of the threaded adjusting piece 13 screwed into the accommodating space 111 is adjusted, the thickness of the cushion piece 14 is synchronously adjusted, and therefore the height of the abutting piece 15 protruding out of the door body 11 is adjusted. The adjustment process can be completed without removing the abutment 15. And further, the distance between the door bodies 11 and the refrigerator body 12 is adjusted, so that the door bodies 11 are positioned in the same plane. The adjusting process is simple and quick, the convenience is higher, and the service performance is effectively improved.

Furthermore, because one end of the screw adjusting piece 13 is limited in the through hole 151, when the door body adjusting device abuts against the refrigerator body 12, the abutting piece 15 abuts against the refrigerator body 12, and the screw adjusting piece 13 does not contact with the refrigerator body 12. That is, the thicknesses of the pad 14 and the abutment 15 determine the distance between the door 11 and the refrigerator body 12.

Specifically, the thickness of the pad 14 can be adjusted by setting the pad 14 to have different specifications, and selecting the pad 14 with a proper specification to be sleeved on the threaded adjusting member 13 according to needs, so as to adjust the distance between the door 11 and the refrigerator body 12. Or the cushion element 14 is set to be in a form of adjustable thickness, the thickness of the cushion element 14 is directly adjusted during the adjustment process, and then the penetration hole 151 acts on the threaded adjusting element 13 to adjust the depth of the threaded adjusting element 13 screwed into the accommodating space 111. One end of the threaded adjusting piece 13 is always limited in the through hole 151, so that the abutting piece 15 is always abutted and pressed against the cushion piece 14, and the purpose of controlling the distance between the door body 11 and the box body is achieved. So that the door bodies 11 are located in the same plane.

Specifically, the threaded adjusting member 13 may be a screw or a bolt. The cushion member 14 may be a ring-shaped member or an arc-shaped member having a notch, or other members that can be pressed between the abutment member 14 and the door body 11.

The storage space 111 may be a hole provided in a case 112 of the door 11 facing the refrigerator body 12. Alternatively, an auxiliary member is provided on an outer side surface of the case 112, and a surface of the auxiliary member facing the refrigerator body 12 is provided with a recess to form the storage space 111. Alternatively, an auxiliary member is provided on the inner surface of the case 112, and a hole penetrating the auxiliary member and the case 112 is provided as the housing space 111.

Further, in one embodiment, as shown in FIG. 2, the perforations 151 include a first segment of holes and a second segment of holes. The first section of hole and the second section of hole are sequentially arranged in the axial direction of the thread adjusting piece 13, and the first section of hole is positioned on one side, close to the door body 11, of the second section of hole. The aperture of the first section of hole is smaller than that of the second section of hole, one end of the thread adjusting piece 13, which is far away from the door body 11, is provided with a limiting part 131, the outer diameter of the limiting part 131 is larger than that of the first section of hole, and the outer diameter of the limiting part 131 is not larger than that of the second section of hole.

When one end of the screw adjusting member 13 is screwed into the receiving space 111 through the through hole 151, the position-limiting portion 131 is sunk into the through hole 151. Based on the outer diameter of the position-limiting part 131 being larger than the aperture of the first section of hole, the outer diameter of the position-limiting part 131 is not larger than the aperture of the second section of hole. That is, the limiting portion 131 will press against the bottom wall formed by the boundary between the second section of hole and the first section of hole, so as to ensure the pressing between the abutting member 15 and the pad member 14.

Optionally, in an embodiment, a protrusion is disposed in the through hole 151, and a limiting portion 131 is disposed at one end of the threaded adjusting piece 13 away from the door body 11, and the limiting portion 131 is pressed on one side of the protrusion away from the door body 11.

After selecting an appropriate pad 14 to be sleeved on the threaded adjusting piece 13 or adjusting the thickness of the pad 14 to an appropriate value, when the threaded adjusting piece 13 is screwed into the accommodating space 111, the limiting part 131 is pressed on the protrusion when the screwing depth is appropriate, so that the abutting piece 15 is pressed with the pad 14, thereby limiting the height of the abutting piece 15 protruding out of the door body 11.

When the threaded adjusting member 13 is a bolt or a screw, the limiting portion 131 is a nut.

Further, as shown in fig. 2 and 3, in one embodiment, a buffer 16 is disposed on an end of the abutting piece 15 away from the door body 11. A through hole 161 is formed in the buffer 16 at a position corresponding to the through hole 151, one end of the screw adjuster 13 can sequentially pass through the through hole 161 and the through hole 151 and be screwed into the receiving space 111, and the buffer 16 can be pressed between the abutting member 15 and the refrigerator body 12.

By further providing the buffer 16, when the door body adjusting device abuts against the refrigerator body 12, the door body adjusting device contacts with the refrigerator body 12 through the buffer 16. When the distance between the refrigerator body 12 and the door body 11 is adjusted, the refrigerator body 12 is protected, and abrasion caused by direct impact of the abutting piece 15 and the refrigerator body is avoided.

Specifically, the buffer 16 may be a rubber member. And the abutment member 15 may be a plastic member.

More specifically, as shown in fig. 2 and 3, in one embodiment, the buffer 16 is an annular sleeve structure. The cushion member 16 is divided into an abutting portion 162 and a connecting portion 163 in the axial direction of the screw adjuster 13, the through hole 161 is provided in the abutting portion 162, the abutting portion 162 is attached to the end surface of the abutting portion 15, the outer ring of the abutting portion 162 is connected to the connecting portion 163, and the connecting portion 163 is fitted to the outer side surface of the abutting portion 15.

That is, the buffer material 16 covers the contact member 15, so that the reliability of the connection between the buffer material 16 and the contact member 15 is ensured, and the buffer material 16 is prevented from falling off. When the door 11 is closed, the abutting portion 162 is pressed between the refrigerator body 12 and the abutting piece 15.

Further, in one embodiment, as shown in fig. 2 and 3, the outer side surface of the abutment member 15 is provided with an annular groove 152, and the connecting portion 163 extends into the annular groove 152. The abutting portion 162 of the buffer 16 abuts against the end surface of the abutting member 15, and the connecting portion 163 extends into the annular groove 152. Thereby further ensuring the reliability of the connection between said abutment 15 and said buffer 16.

Further, as shown in fig. 2 and 3, in one embodiment, the door body adjusting device further includes a sealing member 17 and a nut 18. When the threaded adjustment member 13 is a bolt or screw, the bolt or screw mates with the nut 18. The door body 11 is provided with an adjusting hole on a casing 112 opposite to the refrigerator body 12, and the sealing member 17 is arranged on the inner side surface of the casing 112. I.e. the seal 17 is an auxiliary element arranged on the inner side of the housing 112. The seal 17 is provided with a groove on the side facing the housing 112, in which groove the nut 18 is mounted. And the relative positions of the nut 18 and the housing 112 in the circumferential direction are fixed. The groove and the adjusting hole are opposite to each other to form the accommodating space 111. When the threaded adjusting piece 13 is rotated, the threaded adjusting piece 13 and the nut 18 rotate relatively to each other, so that the effect of screwing is achieved.

The nut 18 is protected by the sealing member 17 disposed on the inner side surface of the casing 112, so that when the foaming process is performed in the door body 11, the sealing member 17 can effectively prevent foaming liquid from entering the nut 18, and the nut 18 and the threaded adjusting member 13 can be rotatably adjusted.

In particular, the seal 17 may protect the nut 18 in the recess by abutting against the inside of the housing 112.

Or, further, to ensure the reliability of the protection of the nut 18 by the sealing member 17, in one embodiment, a limiting shell 113 may be disposed on the inner side surface of the housing 112. The limiting shell 113 surrounds the periphery of the adjusting hole, and the sealing element 17 is inserted in the limiting shell 113. Therefore, under the combined action of the limiting shell 113 and the sealing element 17, foaming liquid cannot enter the groove, and the nut 18 is effectively protected.

Further, in one embodiment, the clearance between the outer side surface of the sealing member 17 and the stopper case 113 is not more than 0.1 mm. Namely, the sealing member 17 and the stopper case 113 can be mounted, but the gap between the sealing member and the stopper case is small, so that the foaming liquid cannot enter the groove to contaminate the nut 18.

Further, in one embodiment, the sidewalls of the recess may be contoured to conform to the outer sidewalls of the nut 18. The outer wall of the nut 18 is generally polygonal and when the nut 18 is placed in the recess, the nut 18 cannot rotate relative to the seal 17. And the relative position of the seal member 17 and the housing 112 in the circumferential direction of the nut 18 is fixed. Therefore, when the thread adjusting piece 13 is rotated, the nut 18 cannot rotate along with the thread adjusting piece 13, and smooth operation of an adjusting process is guaranteed.

Further, as shown in fig. 3, in one embodiment, the outer side surface of the sealing element 17 is enclosed to form a polygon, and the limiting shell 113 is enclosed to form a shape corresponding to the sealing element 17. So that the sealing member 17 is restricted in rotation in the circumferential direction by the stopper case 113. Therefore, when the screw adjusting piece 13 is rotated, the depth of the screw adjusting piece 13 screwed into the accommodating space 111 can be adjusted, and the distance between the refrigerator body 12 and the door body 11 can be controlled.

Further, as shown in fig. 1 and fig. 2, in another embodiment, a refrigerator 10 is provided, which includes a refrigerator body 12 and the door body adjusting device, the door body 11 is disposed corresponding to the refrigerator body 12, and the abutting piece 15 abuts between the pad 14 and the refrigerator body 12.

According to the refrigerator 10 provided by the scheme, the refrigerator body 12 and the door bodies 11 are specifically controlled in a manner of adjusting by the threaded adjusting piece 13, so that the door bodies 11 are positioned in the same plane. Specifically, after the door body adjusting device is assembled, the through hole 151 of the abutting piece 15 directly acts on the threaded adjusting piece 13 located in the through hole 151, the depth of the threaded adjusting piece 13 screwed into the accommodating space 111 is adjusted, the thickness of the cushion piece 14 is synchronously adjusted, and therefore the height of the abutting piece 15 protruding out of the door body 11 is adjusted, and the distance between the refrigerator body 12 abutting against the abutting piece 15 and the door body 11 is adjusted. In the adjusting process, the adjusting process can be completed without detaching or disassembling the abutting part 15, so that the method is simple, convenient and quick, and the service performance of the refrigerator 10 is effectively improved.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
