DETAILED DESCRIPTION

[0040] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all possible embodiments consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

[0041] In this disclosure, the terms "first", "second", etc. are used to distinguish one element from another and do not have order or importance. Figure 6 The up and down directions indicated by the arrows in the figure can also refer to the direction of gravity of the refrigerator, where the height of the door body corresponds to the direction of gravity of the refrigerator. "Inside and outside" refer to the inside and outside of the outline of each component itself. In addition, in the following description, when referring to the drawings, unless otherwise explained, the same figure numbers in different drawings represent the same or similar elements. The above definitions are only used to explain and illustrate this disclosure and should not be understood as limiting this disclosure.

[0042] According to some embodiments of the present disclosure, a door height adjustment device is provided, referring to Figures 1 to 10 As shown in the figure, the door height adjustment device 100 includes: a door body 41; a height adjustment mechanism 1, including a first adjusting member 11 and a second adjusting member 12, the first adjusting member 11 is arranged on the door body 41, and the second adjusting member 12 is used to be rotatably connected to the box body 42 of the refrigerator 4, the second adjusting member 12 has a stud 121 extending in the up and down directions, and the first adjusting member 11 is threadedly connected to the stud 121; and a locking structure 3, which is arranged on the second adjusting member 12 and is configured to be adjustable in distance relative to the first adjusting member 11, so as to selectively limit the rotation of the stud 121 relative to the first adjusting member 11.

[0043] The technical solution provided by the embodiments of the present disclosure can provide the following beneficial effects: when adjusting the height of the door body 41, the distance between the locking structure 3 and the first adjusting member 11 can be adjusted so that the locking structure 3 allows the stud 121 to rotate relative to the first adjusting member 11. At this time, when the stud 121 is rotated, since the first adjusting member 11 is threadedly connected to the stud 121, such a configuration can cause the first adjusting member 11 to move up and down, thereby driving the door body 41 to move up and down, thereby achieving adjustment of the height of the door body 41. When the height of the door body 41 is adjusted, the distance between the locking structure 3 and the first adjusting member 11 can be adjusted again so that the locking structure 3 restricts the stud 121 from rotating relative to the first adjusting member 11. In this way, the stud 121 can be prevented from rotating accidentally, causing an unexpected change in the height of the door body 41, thereby improving the stability of the door body 41. In addition, by arranging the locking structure 3 between the first adjusting member 11 and the second adjusting member 12, the space between the two can be utilized to arrange the locking structure 3, which is conducive to the compact design of the door height adjustment device.

[0044] In the exemplary embodiments provided in the present disclosure, reference is made to Figure 3 As shown in , the locking structure 3 can be constructed as a locking nut, which is threadedly connected to the stud 121. In this way, when it is necessary to adjust the height of the door body 41, the locking nut can be loosened, and the distance between the locking nut and the first adjusting member can be adjusted so that the locking nut and the first adjusting member 11 are spaced apart. At this time, the stud 121 can rotate relative to the first adjusting member 11. When the height of the door body 41 is adjusted, the locking nut can be tightened so that the locking nut abuts against the first adjusting member 11, even if the distance between the locking nut and the first adjusting member is zero. In this way, the stud 121 can be prevented from accidentally rotating relative to the first adjusting member 11.

[0045] In another exemplary embodiment provided by the present disclosure, the locking structure 3 can also be constructed as a telescopic cylinder. When the height of the door body 41 needs to be adjusted, the telescopic rod of the telescopic cylinder can be moved away from the first adjusting member 11 to avoid the first adjusting member 11, that is, the telescopic rod and the first adjusting member are spaced apart. At this time, the stud 121 can rotate relative to the first adjusting member 11. When the height of the door body 41 is adjusted, the telescopic rod is pressed against the first adjusting member 11, that is, the distance between the telescopic rod and the first adjusting member is zero, thereby preventing the stud 121 from accidentally rotating relative to the first adjusting member 11. Of course, the locking structure 3 can also be constructed as any structure such as a top screw that can selectively limit the rotation of the stud 121 relative to the first adjusting member 11. The present disclosure does not make specific limitations on this. It should be noted that when the locking structure 3 is constructed as a top screw, the top screw is set on the first adjusting member 11, and the top screw selectively abuts against the stud 121.

[0046] In the exemplary embodiments provided in the present disclosure, reference is made to Figures 11 to 15 As shown in , the first adjusting member 11 may include a threaded tube 112 having an internal thread 111 and a first flange 113 connected to the threaded tube 112. The stud 121 is threadedly connected to the threaded tube 112, and the locking nut is used to selectively abut against the first flange 113. The provision of the threaded tube 112 is conducive to lightweighting and ensures that there is a sufficient fitting area between the first adjusting member 11 and the stud 121, thereby improving the stability of the structure. In addition, the provision of the first flange 113 increases the contact area between the first adjusting member 11 and the locking nut, thereby improving the smoothness during the height adjustment process of the door body 41 and improving the stability of the door body 41.

[0047] In the exemplary embodiments provided in the present disclosure, reference is made to Figure 16 and Figure 17 As shown in , a first positioning hole 411 may be provided on the door body 41, and the threaded tube 112 is provided in the first positioning hole 411. In the above scheme, the first positioning hole 411 cooperates with the threaded tube 112 to play a positioning role, so that the first adjustment member 11 is positioned and installed on the door body 41. Here, the first positioning hole 411 can be set as a rectangular hole or a polygonal hole, and the outer wall of the threaded tube 112 can be set as a structure that matches the first positioning hole 411. In this way, the threaded tube 112 is prevented from rotating relative to the first positioning hole 411, thereby improving the accuracy and stability of the positioning of the first adjustment member 11, thereby improving the stability of the door body 41.

[0048] In the exemplary embodiments provided in the present disclosure, reference is made to Figure 16 and Figure 17As shown in , the door body 41 may be provided with a positioning groove 412, and the first flange 113 is disposed in the positioning groove 412. In the above technical solution, the positioning groove 412 is adapted to the size of the first flange 113, and the cooperation between the first flange 113 and the positioning groove 412 plays a positioning role, thereby improving the positioning accuracy of the first adjusting member 11.

[0049] In the exemplary embodiments provided in the present disclosure, reference is made to Figure 14 As shown in , the first adjusting member 11 may include a connecting plate 114 connected to the first flange 113, one of the connecting plate 114 and the door body 41 is provided with a positioning column 413, and the other is provided with a second positioning hole 1141, and the positioning column 413 is provided in the second positioning hole 1141. By providing the connecting plate 114, the contact area between the first adjusting member 11 and the door body 41 is increased, which facilitates a better fit between the first adjusting member 11 and the door body 41. By utilizing the cooperation between the positioning column 413 and the second positioning hole 1141, the positioning of the first adjusting member 11 and the door body 41 can be achieved, and the structure is simple and easy to implement. Here, the present disclosure does not impose too many restrictions on the specific structure and shape of the positioning column 413 and the second positioning hole 1141.

[0050] In the exemplary embodiments provided in the present disclosure, reference is made to Figures 2 to 4 as well as Figure 14 As shown in , the connecting plate 114 can be detachably connected to the door body 41 by a fastener 14. The fastener 14 can be a screw or a bolt. In this embodiment, the connecting plate 114 is provided with a first mounting hole 116, and the door body 41 is provided with a second mounting hole 414. The fastener 14 passes through the first mounting hole 116 and is connected to the second mounting hole 414, which is convenient for assembly and disassembly and is stable and reliable.

[0051] To facilitate processing and disassembly, the first positioning hole 411 and the positioning groove 412 can be set on the end cover 43 at the lower end of the door body 41, and the connecting plate 114 can be connected to the end cover 43 through the fastener 14, so as to fix the first adjusting member 11 to the door body 41.

[0052] In the exemplary embodiments provided in the present disclosure, reference is made to Figures 11 to 13 as well as Figure 15 As shown in , the stud 121 may have a through hole 122 extending in the up-down direction, and the height adjustment mechanism 1 further includes a sleeve 13, which is used to be sleeved on the hinge 2 on the box body 42, and the stud 121 is sleeved on the sleeve 13 through the through hole 122. Here, the sleeve 13 can have an interference fit with the through hole 122 to ensure a reliable connection between the stud 121 and the sleeve 13, wherein the hinge 2 may have a mating shaft 21, and the sleeve 13 is used to be sleeved on the mating shaft 21. The sleeve 13 can protect the through hole 122 and the mating shaft 21, avoid wear of the mating shaft 21 and the through hole 122, and increase the durability of the door height adjustment device 100.

[0053] In the exemplary embodiments provided in the present disclosure, reference is made to Figure 13 As shown in , the sleeve 13 may have a second flange 131, and the stud 121 may have a third flange 123, the third flange 123 abutting against the second flange 131, wherein the third flange 123 may be configured as a hexagonal flange. In the above technical solution, the abutment and cooperation between the third flange 123 and the second flange 131 facilitate the installation of the sleeve 13 and the stud 121. In addition, due to the provision of the third flange 123, the rotation of the stud 121 can be controlled by operating the third flange 123, thereby improving the convenience of operation. The third flange 123 is configured as a hexagonal flange, which facilitates the stable cooperation between the operating tool and the third flange 123, thereby facilitating the adjustment of the door body 41. Of course, the present disclosure does not impose too many restrictions on the specific shape of the third flange 123.

[0054] In order to improve the stability of the connection between the sleeve 13 and the stud 121 and facilitate the disassembly and assembly of the sleeve 13, the second flange 131 and the third flange 123 can be connected by a fastener 14. For example, a countersunk hole extending along the axial direction of the sleeve 13 can be provided on the second flange 131, and a threaded hole corresponding to the countersunk hole can be provided on the sleeve 13. The screw is passed through the countersunk hole and connected to the threaded hole, and the outer end of the screw is kept in the countersunk hole.

[0055] In the exemplary embodiments provided in the present disclosure, reference is made to Figure 11 、 Figure 18 and Figure 19 As shown in , the sleeve 13 may have a second flange 131, the hinge 2 has a mating shaft 21 extending in the up-down direction and a fourth flange 22 connected to the mating shaft 21, the sleeve 13 is used to be sleeved on the mating shaft 21, and the second flange 131 is used to abut against the fourth flange 22. By providing the fourth flange 22, the sleeve 13 is separated from the main body of the hinge 2, avoiding the normal rotation of the sleeve 13 being affected by the contact between the sleeve 13 and the main body of the hinge 2, ensuring the smooth opening and closing of the door body 41 and improving the user experience. In addition, the provision of the second flange 131 increases the abutment area between the sleeve 13 and the fourth flange 22, thereby improving the stability of the sleeve 13.

[0056] In the exemplary embodiments provided in the present disclosure, reference is made to Figure 5As shown in , the first adjusting member 11 can be provided with a stop plate 115, and the second adjusting member 12 is used to be connected to the hinge 2 of the box body 42. When the door body 41 is opened to the preset position, the stop plate 115 abuts against the hinge 2. The preset position can be the maximum position required for the door body 41 to be opened. The preset position can be set according to actual needs. On the basis of the above technical solution, an abutting protrusion 23 can be provided on the hinge 2. In this way, when the door body 41 is opened to the preset position, the stop plate 115 can abut against the abutting protrusion 23 to limit the door body 41 from continuing to rotate in the opening direction. It can be understood that the stop plate 115 can also be provided on the door body 41 and the abutting protrusion 23 can be provided on the hinge 2, or any other structure that can limit the door body 41 from continuing to rotate in the opening direction when the door body 41 is opened to the preset position can be adopted. The present disclosure does not impose specific restrictions on this.

[0057] In order to more accurately ensure the position of the door body 41 when it is closed, in some embodiments, a door closing stopper 5 can be provided. The door closing stopper 5 is provided on the door body 41. When the door body 41 is in a closed state, the door closing stopper 5 abuts against the hinge 2.

[0058] On the basis of the above technical solution, the present disclosure also provides a refrigerator 4, which includes a box body 42 and the above-mentioned door height adjustment device 100, and the door height adjustment device 100 can be rotatably connected to the box body 42.
