[0044] The mounting seat 12 includes the base plate 121 transmission connection in connecting rod assembly 13, and the mounting piece 122 installed in the refrigerator door body, and the base plate 121 and the mounting piece 122 between being equipped with up and down adjustment structure 123, guide structure 124 and fixed structure 125, up and down adjustment structure 123 can make mounting piece 122 drive refrigerator door body moves up and down, guide structure 124 is used for the movement guide of mounting piece 122, fixed structure 125 can fixedly connect base plate 121 and mounting piece 122.

[0045] Specifically, the fixed seat 11 is installed on the refrigerator body, the mounting seat 12 is installed on the refrigerator door body, one end of the connecting rod assembly 13 is drivingly connected with the fixed seat 11, and the other end is drivingly connected with the mounting seat 12, so as to realize the installation of the refrigerator door body and the refrigerator body, and enable the refrigerator door body to be opened and closed. Alternatively, the fixed seat 11 is fastened and installed on the refrigerator body by means of fasteners such as screws and bolts, so as to not only facilitate the installation of the hinge structure 1 and the refrigerator body, but also ensure the installation stability. However, due to manufacturing and installation errors, the actual installation position of the refrigerator door body often deviates from the designed position, which not only affects the overall appearance of the refrigerator and the user's perception, but also may affect the sealing effect of the internal space of the refrigerator and the refrigeration effect. In order to overcome this problem, the refrigerator door body often adopts an adjustable installation, that is, the relative position of the hinge structure 1 and the refrigerator door body is adjustable, that is, the mounting seat 12 and the refrigerator door body are adjustable.

[0046] Therefore, the mounting seat 12 comprises a base plate 121 and a mounting piece 122, the base plate 121 is used for driving connection with the connecting rod assembly 13, and the mounting piece 122 is used for connecting the mounting seat 12, so as to set an up-down adjustment mechanism between the mounting piece 122 and the base plate 121, the up-down adjustment mechanism can enable the mounting piece 122 to move up and down relative to the base plate 121, so as to realize the fine adjustment of the position of the refrigerator door body in the up-down direction. In addition, the base plate 121 and the mounting piece 122 are also provided with a guide structure 124, which can limit the movement direction of the mounting piece 122 and guide the movement of the mounting piece 122. Since the refrigerator door body has a certain weight, and the base plate 121 and the mounting piece 122 are adjustable, in order to reduce the possibility of accidental downward movement of the refrigerator door body due to its own weight, the base plate 121 and the mounting piece 122 are also provided with a fixing structure 125, which can ensure the relative fixation of the base plate 121 and the mounting piece 122 after the refrigerator door body is adjusted to the target position. When it is necessary to adjust the position of the refrigerator door body, the fixing function of the fixing structure 125 can be released. Therefore, in the present scheme, by setting the up-down adjustment structure 123, the guide structure 124 and the fixing structure 125 between the base plate 121 and the mounting piece 122, the stable position adjustment of the refrigerator door body in the up-down direction can be realized, and the stable fixation of the refrigerator door body relative to the refrigerator body can be ensured, and the modular division of labor can be realized.

In the left-right direction, accidental displacement will not occur due to the gravity of the refrigerator door body itself, so that only the left-right adjustment structure can be provided between the fixing plate and the second mounting part 127, and the guide structure 124 can also be provided to further guide the relative movement of the fixing plate and the second mounting part 127, and the guide structure 124 can also have a certain fastening function (such as being matched with a left-right extending guide hole in the form of a screw or a rivet), thereby reducing the possibility of accidental movement of the refrigerator door body. Of course, in other embodiments, the fixing plate and the second mounting part 127 can also be provided with the left-right adjustment structure, the guide structure 124 and the fixing structure 125. If the hinge structure 1 can only realize the up-down adjustment of the refrigerator door body, the mounting member 122 can be directly fixedly connected to the refrigerator door body.

[0048] The specific structure of the left-right adjustment structure can be completely the same as that of the up-down adjustment structure 123, only the installation position and the adjustment direction are different, so as to improve the part universality and facilitate the installation of the hinge structure 1. Further, the specific structure of the guide structure 124 and the fixing structure 125 between the fixing plate and the second mounting part 127 can also be the same as that of the guide structure 124 and the fixing structure 125 between the first mounting part 126 and the base plate 121, and of course it can also be different. The up-down direction is the up-down direction when the refrigerator is normally used, that is, the height direction of the refrigerator, and the left-right direction is the left-right direction when the refrigerator is normally used, that is, the width direction of the refrigerator, wherein the left-right direction is parallel to the plane where the opening of the refrigerator body is located (when the refrigerator door body is closed, the left-right direction is parallel to the plane where the refrigerator door body is located).
