[0034] After the refrigerator door is installed on the refrigerator body, there may be a certain deviation in the up and down direction. Therefore, it is necessary to adjust the refrigerator door in the up and down direction. Currently, in the prior art, for the adjustment of the refrigerator door, an adjustment shaft is provided on the hinge at the bottom of the upper refrigerator door, and the adjustment of the door is achieved by the up and down movement of the adjustment shaft. Currently, the adjustment of the adjustment shaft is in the form of setting an adjustment flange on the movable seat of the hinge. Since the distance between the movable seat and the upper refrigerator door is small, the overall thickness of the adjustment flange will be made relatively small, generally not exceeding 1.8 mm, and the thickness of the wrench is also similar to be inserted. Using a very thin wrench to adjust a very thin adjustment flange, on the one hand, due to the very thin adjustment flange, the strength of the six edges is not high, and it is easy to cause the coating originally attached to its surface to fall off during the adjustment process in cooperation with the wrench, resulting in a corrosion risk. On the other hand, the adjustment space is small, resulting in poor adjustability.
[0035] The present utility model proposes a refrigerator hinge 10, please refer to Figures 1 to 3 , the refrigerator hinge 10 includes a fixed seat 30, a movable seat 40 and an adjustment shaft 20. The fixed seat 30 is used for fixedly installing to the refrigerator body 60. The movable seat 40 is rotatably installed on the fixed seat 30. The movable seat 40 is provided with a threaded hole 41 along its thickness direction. The adjustment shaft 20 is rotatably installed in the threaded hole 41. The adjustment shaft 20 is the adjustment shaft 20 as described above.
[0036] Specifically, the fixed seat 30 is used for being fixedly installed on the box body 60 of the refrigerator, so as to play a supporting role for the installation of the movable seat 40. The movable seat 40 is used for being installed on the door of the refrigerator. It is rotatably installed on the fixed seat 30. Thus, when the door of the refrigerator rotates, the movable seat 40 can rotate together with the door of the refrigerator. The adjusting shaft 20 is rotatably installed in the threaded hole 41. Thus, by rotating the adjusting shaft 20, the up-and-down position of the adjusting shaft 20 on the movable seat 40 is adjusted. Moreover, the adjusting shaft 20 abuts against the door of the refrigerator. Therefore, when the up-and-down position of the adjusting shaft 20 changes, the up-and-down position of the door of the refrigerator will also change accordingly, so as to realize the adjustment of the up-and-down position of the door of the refrigerator.
[0037] The adjusting shaft 20 will be specifically described below. Please refer to Figure 4 and Figure 5 , the adjusting shaft 20 has a mounting section 21, an adjusting section 22 and an operating section 23 which are arranged in sequence along its length direction. At least part of the mounting section 21 is used for being fixedly installed on the door body 50 of the refrigerator. The adjusting section 22 is used for being rotatably installed on the movable seat 40 of the refrigerator hinge 10 and is threadedly connected with the movable seat 40 of the refrigerator hinge 10, so as to adjust the up-and-down position of the adjusting shaft 20 by rotating the adjusting section 22. The operating section 23 is used for being operated by the user to rotate the adjusting section 22.
[0038] In the technical solution of the present utility model, the adjusting shaft 20 has a mounting section 21, an adjusting section 22 and an operating section 23 which are arranged in sequence along its length direction, so that the mounting section 21 and the operating section 23 are respectively arranged on both sides of the length direction of the adjusting section 22. When the adjusting shaft 20 is installed on the movable seat 40 of the refrigerator hinge 10, since at least part of the adjusting section 22 is located in the threaded hole 41 of the movable seat 40 of the refrigerator hinge 10, therefore, during installation, the operating section 23 can also be located in the threaded hole 41 of the movable seat 40 of the refrigerator hinge 10 or on the lower side of the movable seat 40 of the refrigerator hinge 10, and is no longer located on the upper side of the movable seat 40 of the refrigerator hinge 10, and is not restricted by the space between the movable seat 40 of the refrigerator hinge 10 and the bottom of the door body 50 of the refrigerator, which is convenient for the user to operate. Moreover, the thickness of the operating section 23 can be increased to enhance the strength of the operating section 23, and the stability of the adjusting shaft 20 during the adjustment process is improved.
[0039] It should be noted that external threads adapted to the threaded hole 41 are provided on the outer side of the adjusting section 22, so as to change the position of the adjusting shaft 20 in the up-and-down direction on the movable seat 40 under the rotation of the adjusting section 22.
[0040] The refrigerator 100 can be a triple-door refrigerator. The refrigerator hinge 10 can be provided at the bottom of the door body 50 of any refrigerator. The refrigerator 100 can also be a side-by-side refrigerator or a two-door refrigerator, etc., which is not limited herein.
[0041] The number of the adjustment shafts 20 provided is not limited. It can be one or multiple, which is not limited herein. In one embodiment, multiple adjustment shafts 20 are provided, so that multiple positions at the bottom of the door body 50 of the refrigerator can be adjusted, further improving the effect of adjusting the door body 50 of the refrigerator.
[0042] The specific implementation form of the operation section 23 is not limited. When the operation section 23 is located outside the threaded hole 41, that is, on the side of the movable seat 40 facing away from the door body 50 of the refrigerator, the operation section 23 can be an external hexagon section. By setting the outer shaft side of the operation section 23 to a regular hexagon shape, a user can directly operate the operation section 23 with an ordinary wrench or an external hexagon socket wrench. Of course, it can also be set as an internal hexagon section, that is, an internal hexagon operation hole is opened at the end of the operation section 23, so that the user can directly operate the operation section 23 with an internal hexagon wrench 200 from the side of the movable seat 40 facing away from the door body 50 of the refrigerator, rotate the adjustment shaft 20, and adjust the movement of the adjustment shaft 20 in the up and down direction, etc., which is not limited herein.
[0043] Certainly, when the operation section 23 is installed, it can also be entirely located within the threaded hole 41, that is, the adjustment shaft 20 does not extend to the side of the movable seat 40 facing away from the door body 50 of the refrigerator. At this time, it can be avoided that the operation section 23 of the adjustment shaft 20 extends out of the movable seat 40 and interferes with the movement of other objects. In particular, when the hinge is applied between the upper and lower doors of a two-door refrigerator, once the operation section 23 of the adjustment shaft 20 extends out of the movable seat 40, when the lower door is opened or closed and rotates, the operation section 23 is likely to interfere with the lower door and hinder the movement of the lower door.
[0044] At this time, correspondingly, the operation section 23 can be an external hexagonal section. By setting the outer shaft side of the operation section 23 to the shape of a regular hexagon, and the size of the operation section 23 should be smaller than the size of the threaded hole 41, so as to leave a gap between the operation section 23 and the threaded hole 41, allowing the user to use an external hexagonal socket wrench to extend into the gap and operate the operation section 23 to adjust the position of the adjustment shaft 20 in the up and down directions to adjust the refrigerator door. It can also be in the form of an internal hexagonal section, so that the user can use an internal hexagonal wrench 200 from the outside to extend into the wrench hole 24 opened at the end of the operation part and operate the operation section 23.
[0045] Of course, in addition to being operated by a wrench, the operation section 23 can also be operated by a screwdriver. For example, a slotted screw hole, a Phillips screw hole, etc. are opened at the end of the operation part, which is not limited here.
[0046] In addition, it can also be configured to be operated by other operation tools. For example, the operation section 23 is configured to be connectable by a coupling, so that the user can use a combination of an electric screwdriver and a coupling to operate the operation section 23, etc., which is not limited here.
[0047] In an embodiment, the operation section 23 is configured to be operable by a wrench. It can be understood that when the refrigerator hinge 10 is installed between the upper and lower doors of a double-door refrigerator, limited by the space between the upper and lower doors, if the operation tool requires a large up and down space, such as when using an electric screwdriver or a screwdriver for operation, a large operation space is required. At this time, only the lower door of the refrigerator can be disassembled, and the operation is more cumbersome, or only the upper door can be adjusted first, and then the lower door can be installed later.
[0048] The operation of a wrench has low requirements for the up and down space, and the door does not need to be disassembled to operate the operation section 23 of the adjustment shaft 20. Specifically, the operation section 23 can be configured as an external hexagonal section, or an internal hexagonal section, etc., as long as it can be operated by a wrench.
[0049] In the solution of this embodiment, the operation section 23 is configured to be operable by a wrench, so that during the operation of the operation section 23 of the adjustment shaft 20, even in a relatively narrow operation space, the operation section 23 can be correspondingly operated. Moreover, the cost of a wrench is low and it can be seen everywhere in daily life. The user can use it by himself to adjust the operation section 23 to adjust the door body 50 of the refrigerator.
[0050] When being operated by the wrench, the operation section 23 can be operated by the wrench on its outer peripheral side, or a wrench hole 24 can be opened at its end. When being operated by the wrench on its outer peripheral side, the outer peripheral side can no longer cooperate with the threaded hole 41, so that the adjustment stroke of the adjustment shaft 20 is short. Moreover, when the operation section 23 is located in the threaded hole 41, limited by the size of the threaded hole 41, it is also difficult to operate the operation section 23.
[0051] Therefore, in one embodiment, a wrench hole 24 is opened at the end of the operation section 23, so that the user can use a wrench to extend into the wrench hole 24 to operate the operation section 23, so as to rotate the adjustment section 22 and adjust the position of the adjustment shaft 20 in the up and down direction.
[0052] Specifically, the wrench hole 24 is polygonally arranged. The wrench hole 24 can be an internal hexagonal wrench 200 hole, an internal octagonal wrench hole 24, etc., which is not limited herein.
[0053] The depth of the wrench hole 24 cannot be too shallow. Otherwise, the strength of the operation section 23 is insufficient. During the process of operating the operation section 23 through the wrench hole 24, the coating at the wrench hole 24 is likely to be damaged or even fall off, causing a corrosion risk.
[0054] Of course, the depth of the wrench hole 24 cannot be too large either. Otherwise, it may affect the overall strength of the adjustment shaft 20. Therefore, in a further embodiment, the depth of the wrench hole 24 is 1.8 - 3.5 mm. The thickness of the existing adjustment shaft flange is very thin, usually not exceeding 1.8 mm, resulting in weak strength. Therefore, in this embodiment, the depth of the wrench hole 24 is greater than or equal to 1.8 mm, which is greater than the thickness of the existing adjustment shaft flange, increasing the strength. And the depth of the wrench hole 24 is less than or equal to 3.5 mm, avoiding too much influence on the overall strength of the adjustment shaft 20 due to excessive opening, and ensuring the overall strength of the adjustment shaft 20.
[0055] In one embodiment, the operation section 23 is an internal hexagonal section, so that the user can use an internal hexagonal wrench 200 to operate the operation section 23. Compared with other wrenches, the internal hexagonal wrench 200 is usually small in size, light in weight, convenient to carry and use. At the same time, due to its strong structure, it is not easy to be damaged during normal use, and the six contact points evenly distribute the pressure, reducing the risk of damage to the coating of the wrench hole 24.
[0056] Of course, the aperture diameter of the wrench hole 24 cannot be too small. If it is too small, the corresponding wrench will be very thin, and the driving force it can transmit will be small, making it difficult to operate the operating section 23. Therefore, the aperture diameter of the wrench hole 24 is a, where 3 mm ≤ a, so as to ensure that the wrench has sufficient strength to transmit sufficient driving force and ensure smooth operation. Similarly, due to the limitation of the size of the threaded hole 41, the size of the wrench hole 24 cannot be too large, otherwise the size difference from the threaded hole 41 is too small, resulting in a relatively thin thickness of the operating section 23 and relatively small strength of the operating section 23, making it easy for the wrench to damage the coating and cause the coating to fall off. Therefore, a ≤ 6 mm, so as to ensure the thickness of the operating section 23 and enable it to have sufficient strength to bear the driving force transmitted by the wrench.
[0057] Further, in an embodiment, the outer diameter of the operating section 23 is the same as that of the adjusting section 22, and threads are provided on the outer peripheral sides of both the operating section 23 and the adjusting section 22. With this setting, in the technical solution of this embodiment, by providing threads on the outer peripheral sides of both the operating section 23 and the adjusting section 22, the operating section 23 can also be threadedly engaged with the threaded hole 41 through threads, thereby increasing the adjustable range of the adjusting shaft 20 in the up and down directions.
[0058] Moreover, since the outer diameter of the operating section 23 is the same as that of the adjusting section 22, in the production process, the operating section 23 and the adjusting section 22 can be processed using the same set of processes first, and then holes can be opened at the end of the operating section 23, simplifying the production process.
[0059] To improve the stability of the support for the door body 50 of the refrigerator, a flange 25 is provided at the adjacent position of the adjusting section 22 and the mounting section 21. In the solution of this embodiment, by providing the flange 25, the contact area between the adjusting shaft 20 and the door body 50 of the refrigerator can be increased, thereby improving the stability of the support for the door body 50 of the refrigerator.
[0060] Currently, in order for the flange of the adjusting shaft to be operable by a wrench, the shape of its outer side is an external hexagon with six edges, which is very likely to be self-locked and interfere with or rub against the plastic parts on the refrigerator door body 50 during actual use, resulting in abnormal opening and closing of the door body 50. After changing the position of the operating section 23, during the rotation of the adjusting shaft 20, it is no longer necessary to operate the flange 25. Therefore, to prevent interference between the flange 25 and the plastic parts on the door body 50, the outer peripheral side of the flange 25 is circularly arranged, ensuring smooth, non-stuck, and non-interfering phenomena during the opening and closing process of the door body 50, with good stability.
[0061] To achieve the above object, the present application also proposes a refrigerator 100, including the refrigerator hinge 10 described above.
[0062] The refrigerator 100 adopts all the technical solutions of the above-mentioned all embodiments, and thus has at least all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be elaborated one by one here.
[0063] The above description is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structural transformation made under the technical concept of the present invention by using the content of the specification and drawings of the present invention, or directly / indirectly applied in other related technical fields, is included in the patent protection scope of the present invention.
