[0050] The term "and / or" is a description of the association relationship between objects, indicating that three relationships can exist. For example, A and / or B means: A or B, or, A and B.

[0051] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure may be combined with each other.

[0052] Combination Figures 1 to 8 As shown, the embodiment of the present disclosure provides a hinge device, including: a hinge body 10, a positioning column 20 and a bolt 30. The hinge body 10 is provided with a column slot 101 and a plug hole 102 whose axes are perpendicular to each other; the positioning column 20 is inserted into the column slot 101 and is configured with a threaded hole 201 perpendicular to the axis; the bolt 30 is inserted into the plug hole 102 and the threaded hole 201; wherein, when the bolt 30 abuts against the edge of the plug hole 102 and rotates, the positioning column 20 moves in the column slot 101 along the axis of the bolt 30.

[0053] The hinge device of this embodiment can be applied to the door body 50 of a refrigeration device (such as a refrigerator), and the hinge device can be used to solve the problem of unevenness of the door body 50.

[0054] Exemplarily, the hinge body 10 is mounted on the crossbeam or the side wall of the refrigerator. The area where the column groove 101 of the hinge body 10 is located is arranged horizontally, and the positioning column 20 is vertically penetrated in the column groove 101. At least one end of the positioning column 20 is connected to the door body 50, and the other end can be connected to the box. The bolt 30 is penetrated in the socket 102 and the threaded hole 201, and the socket 102 is used to limit and guide the installation of the bolt 30, so as to ensure that when the bolt 30 is connected and rotated with the positioning column 20, the bolt 30 is prevented from rotating around the positioning column 20. When the bolt 30 rotates, the positioning column 20 moves along the axis of the bolt 30 in the column groove 101 under the action of the threaded connection with the bolt 30. During the movement, the positioning column 20 abuts against the door body 50, thereby driving the door body 50 to move along the axis of the bolt 30. Based on the positioning column 20 being located on one side of the door body 50, when the door body 50 is driven to move, the other side of the door body 50 can be lifted upward, solving the problem of uneven door body 50.

[0055] The hinge device provided by the embodiment of the present disclosure is used to limit and guide the installation of the bolt 30 by using the insertion hole 102, so as to ensure that when the bolt 30 is connected and rotated with the positioning column 20, the bolt 30 is prevented from rotating around the positioning column 20. The bolt 30 rotates, driving the positioning column 20 to move along the axis of the bolt 30 in the column groove 101, thereby driving the door body 50 to move; since the positioning column 20 is located on one side of the door body 50, when driving the door body 50 to move, the other side of the door body 50 can be lifted upward, solving the problem of uneven door body 50.

[0056] Optionally, the hinge body 10 includes a bottom plate 103 and a protrusion 104 extending upward from the bottom plate 103, wherein the bottom plate 103 is configured with a column groove 101, and the protrusion 104 is configured with a socket 102. Exemplarily, in actual use, the bottom plate 103 is placed horizontally, and the protrusion 104 is configured to extend upward from the upper surface of the bottom plate 103. The column groove 101 is set through the bottom plate 103, and the socket 102 is set through the protrusion 104. It should be noted that the column groove 101 and the socket 102 are through holes and have no threaded structure.

[0057] For example, the insertion hole 102 and the column slot 101 do not interfere with each other, and the orthographic projection of the insertion hole 102 and the top surface of the column slot 101 do not interfere with each other. In this way, it is possible to avoid the bolt 30 being inserted into the insertion hole 102 and the column slot 101 at the same time, thereby increasing the accuracy of the hinge device, resulting in a decrease in the scrap rate and production efficiency; thereby reducing the assembly efficiency. In addition, it is also helpful to avoid reducing the structural strength of the bottom plate 103 when the bolt 30 is inserted into the column slot 101.

[0058] It should be noted that, in actual use, the bolt 30 can be inserted into the insertion hole 102 and the column groove 101 at the same time.

[0059] Optionally, the column slot 101 of the hinge body 10 is oval or rectangular, and the width of the column slot 101 is slightly larger than the diameter of the positioning column 20, so as to avoid the positioning column 20 abutting against the column slot 101, thereby affecting the movement of the positioning column 20. In addition, the length of the column slot 101 is much larger than the diameter of the positioning column 20. In this way, it can be ensured that the positioning column 20 moves in the column slot 101 under the drive of the bolt 30, so as to achieve the purpose of adjusting the unevenness of the door body 50.

[0060] When the bolt 30 is rotated, the bolt 30 is stopped by the protrusion 104 where the insertion hole 102 is located and can only move along the axial direction. The positioning column 20 is threadedly connected with the bolt 30. Under the drive of the bolt 30, the positioning column 20 moves along the axis of the bolt 30 and can only move within the column groove 101 due to the restriction of the column groove 101. During the movement of the positioning column 20, the side of the door body 50 connected to the positioning column 20 is stressed, so that the other side of the door body 50 is lifted upward. At this time, the moving direction of the positioning column 20 is opposite to the insertion direction of the bolt 30.

[0061] Optionally, the column slot 101 is elliptical or rectangular, and a center line of the column slot 101 in a width direction is parallel to an axis of the insertion hole 102 .

[0062] The column groove 101 is elliptical or rectangular, and is used to limit the movement trajectory of the positioning column 20 to ensure that the positioning column 20 moves along the axial direction of the bolt 30 to avoid deviation.

[0063] The center line of the column slot 101 in the length direction is designed to be perpendicular to the axis of the socket 102, so as to ensure that the axis of the bolt 30 inserted from the socket 102 is parallel to the center line of the column slot 101 in the length direction, thereby ensuring that the moving direction of the positioning column 20 in the column slot 101 matches the length direction of the axis of the bolt 30 to avoid jamming.

[0064] Optionally, the hinge body 10 includes a bottom plate 103 and a protrusion 104 extending upward from the bottom plate 103 ; wherein the bottom plate 103 is configured with the column groove 101 , and the protrusion 104 is configured with the insertion hole 102 .

[0065] The protrusion 104 may be a plate-like structure, which is not only helpful for processing, but also helps to improve the aesthetics of the hinge body 10. Optionally, the thickness of the protrusion 104 is less than the thickness of the bottom plate 103. In this way, it helps to reduce the weight of the hinge body 10. Exemplarily, the protrusion 104 is equivalent to a hanging ear structure protruding from the edge of the bottom plate 103 of the hinge body 10.

[0066] The protrusion 104 in this embodiment mainly serves to guide the installation of the bolt 30 and to limit the rotation of the bolt 30. In actual use, the head of the bolt 30 abuts against the protrusion 104, and the screw portion of the bolt 30 passes through the insertion hole 102 of the protrusion 104.

[0067] Optionally, the positioning column 20 includes: a column 202 including a threaded section 204 ; a ring 203 formed around the circumference of the column 202 and protruding from the column 202 ; wherein the threaded hole 201 passes through the ring 203 , and the axis of the hole is perpendicular to the axis of the ring 203 .

[0068] The column 202 and the ring 203 are coaxially arranged, and the ring 203 protrudes from the column 202. When the positioning column 20 is inserted into the column slot 101, the length of the column 202 passing through the column slot 101 can be limited by the ring 203. Therefore, when the positioning column 20 is assembled with the hinge body 10, the ring 203 abuts against the bottom plate 103 of the hinge body 10 to limit the installation position of the column 202 and the hinge body 10.

[0069] The positioning column 20 is provided with a threaded hole 201 perpendicular to the axis, and the threaded hole 201 penetrates the positioning column 20. In this embodiment, the threaded hole 201 is provided at the ring body 203 and the column body 202, and penetrates the ring body 203. In this way, when the bolt 30 is inserted into the threaded hole 201, it helps to increase the contact area between the bolt 30 and the positioning column 20, especially the threaded hole 201 section located on the ring body 203, which can limit and guide the bolt 30, avoid the contact section between the bolt 30 and the column body 202 being too small, and the bolt 30 generates an angle with the column body 202 when moving, thereby affecting the smoothness of movement of the bolt 30 and the positioning column 20.

[0070] The threaded hole 201 passes through the ring body 203 and the axis of the hole is perpendicular to the axis of the ring body 203, ensuring that the bolt 30 and the ring body 203 are arranged in parallel, and the bolt 30 and the positioning column 20 are arranged vertically, thereby ensuring the movement direction of the bolt 30 and the positioning column 20 and avoiding interference and jamming problems.

[0071] Optionally, the ring body 203 is located in the middle of the column 202 , and the threaded section 204 of the column 202 extends from the ring body 203 to the end.

[0072] The ring body 203 is set in the middle of the column 202. When the bolt 30 drives the positioning column 20 to move, it not only helps the positioning column 20 to be evenly stressed, but also the force transmitted to both ends by the positioning column 20 is also even, avoiding serious deviation at either end, thereby affecting the effect of adjusting the position of the door body 50.

[0073] The threaded section 204 of the column 202 extends from the ring body 203 to the end. In this way, when the positioning column 20 is assembled with the base plate 103 of the hinge body 10, the positioning column 20 can not only adapt to base plates 103 of different thicknesses, but also ensure that the ring body 203 is abutted and fixed to the base plate 103, thereby improving stability.

[0074] Optionally, the threaded hole 201 is located at the connection between the ring body 203 and the column 202 , and the threaded hole 201 and the threaded section 204 are located on both sides of the ring body 203 .

[0075] The threaded hole 201 is set at the connection between the ring body 203 and the column 202. When the bolt 30 is inserted into the threaded hole 201, the bolt 30 not only contacts the column 202, but also contacts the ring body 203, thereby increasing the contact area and connection length between the bolt 30 and the positioning column 20. The threaded hole 201 section located on the ring body 203 can limit and guide the bolt 30 to avoid the contact section between the bolt 30 and the column 202 being too small, thereby preventing the bolt 30 from generating an angle with the column 202 when moving, thereby affecting the smoothness of movement of the bolt 30 and the positioning column 20.

[0076] The threaded hole 201 and the threaded section 204 are respectively located on both sides of the ring body 203 , so as to avoid interference between the installation of the bolt 30 and the positioning column 20 and the installation of the positioning column 20 and the bottom plate 103 of the hinge body 10 .

[0077] Optionally, the hinge device further includes: a nut 40 threadedly connected to the threaded section 204 of the positioning column 20 ; wherein the nut 40 and the ring body 203 are respectively located on two sides of the hinge body 10 .

[0078] The positioning post 20 is inserted into the post slot 101 of the hinge body 10 , and the nut 40 prevents the positioning post 20 from falling off the hinge body 10 .

[0079] When the positioning column 20 is inserted into the column groove 101, the nut 40 and the ring body 203 are respectively located on both sides of the hinge body 10, i.e., the base plate 103. In this way, the nut 40 and the ring body 203 abut against both sides of the base plate 103 to fix the positioning column 20 on the base plate 103 to prevent it from shaking, thereby affecting the assembly angle of the positioning column 20 and the bolt 30 when the bolt 30 rotates, and thus the smoothness of the movement of the positioning column 20.

[0080] Optionally, a guide structure 205 is configured at the end of the positioning column 20 to facilitate the positioning column 20 to be installed on the door body 50 .

[0081] By constructing the guide structure 205 at the end of the positioning column 20 , when the positioning column 20 is inserted into the door body 50 , it is convenient for the positioning column 20 to be inserted into the door body 50 .

[0082] Optionally, the limiting structure is a plurality of planes constructed from the end of the positioning column 20. Optionally, the plurality of planes are arranged to intersect.

[0083] The projection area of ​​the end with the guide structure 205 is smaller than the cross-sectional area of ​​the column 202 of the positioning column 20. In this way, the guide structure 205 helps the positioning column 20 to be smoothly installed in the door body 50, that is, it plays a role of guiding installation.

[0084] Combination Figures 1 to 8 As shown, an embodiment of the present disclosure provides a refrigeration device, including a door body 50 and a hinge device provided in the above embodiment. The hinge device includes: a hinge body 10, a positioning column 20 and a bolt 30. The hinge body 10 is provided with a column groove 101 and a socket 102 with axes perpendicular to each other; the positioning column 20 is inserted into the column groove 101 and is configured with a threaded hole 201 perpendicular to the axis; the bolt 30 is inserted into the socket 102 and the threaded hole 201; wherein, when the bolt 30 abuts against the edge of the socket 102 and rotates, the positioning column 20 moves in the column groove 101 along the axis of the bolt 30.

[0085] The refrigeration device provided by the embodiment of the present disclosure uses the insertion hole 102 to limit and guide the installation of the bolt 30, so as to ensure that when the bolt 30 is connected and rotated with the positioning column 20, the bolt 30 is prevented from rotating around the positioning column 20. The bolt 30 rotates, driving the positioning column 20 to move along the axis of the bolt 30 in the column groove 101, thereby driving the door body 50 to move; since the positioning column 20 is located on one side of the door body 50, when driving the door body 50 to move, the other side of the door body 50 can be lifted upward, solving the problem of uneven door body 50.

[0086] The refrigeration equipment provided in this embodiment may be a refrigerator, a freezer, a wine cabinet, a display cabinet, etc.

[0087] Optionally, a mounting hole 501 is configured at the top and / or bottom of the door body 50, and the positioning column 20 of the hinge device is inserted into the mounting hole 501 of the door body 50 to drive the door body 50 to move when the positioning column 20 moves.

[0088] The positioning column 20 of the hinge device is inserted into the mounting hole 501 of the door body 50 and is located on one side of the door body 50. Under the action of the rotation of the bolt 30, the positioning column 20 moves in the opposite direction of the insertion of the bolt 30, thereby driving the side of the door body 50 connected to the positioning column 20 to deviate in the opposite direction of the insertion of the bolt 30, and then the other side of the door body 50 is lifted upward, so as to adjust the unevenness of the door body 50.

[0089] For example, one side of the door body 50 is rotatably connected to the box of the refrigeration device, and the other end is a free end. During use, due to its own gravity, the free end of the door body 50 will move downward, resulting in the problem of uneven door body 50. Figure 3 For the convenience of description, the state of the door body 50 when it is not aligned is defined as state 1 50a, and the corresponding position of the positioning post 20 is position 1 20a; the state of the door body 50 when it is aligned is defined as state 2 50b, and the corresponding position of the positioning post 20 is position 20b.

[0090] When the door body 50 is not aligned, the door body 50 is in state 1, and the positioning column 20 is in position 1. By rotating the bolt 30 of the hinge device, the positioning column 20 moves from position 1 to position 2 under the action of the bolt 30, and the door body 50 is driven by the positioning column 20 to adjust from state 1 to state 2, thereby solving the problem of the uneven door body 50.

[0091] The above description and the accompanying drawings sufficiently illustrate the embodiments of the present disclosure to enable those skilled in the art to practice them. Other embodiments may include structural and other changes. The embodiments represent only possible variations. Unless explicitly required, individual components and functions are optional, and the order of operations may vary.
