Please refer to FIG. 3 to FIG. 13 , in some embodiments, a fitting portion 601 is formed on the top of the guide block 6 , and the fitting portion 601 is flat and fits into the mounting hole 32 on the mounting base 3 . The fitting portion 601 is embedded in the assembly hole 32 so that the guide block 6 is circumferentially fixed on the mounting base 3 . The top openings of the shaft hole 61 and the pin hole 62 are exposed on the top surface of the fitting portion 601, therefore, the top openings of the shaft hole 61 and the pin hole 62 can be exposed to the assembly hole 32, so that the shaft portion 51 of the knob 5 and the shaft pin 52 are aligned and inserted into the shaft hole 61 and the pin hole 62. When the knob 5 rotates relative to the guide block 6, because the fitting part 601 is embedded in the assembly hole 32, the guide block 6 will not rotate with the knob 5 in the circumferential direction, so the shaft portion 51 and the shaft pin 52 of the knob 5 can be relatively guided. Block 6 rotates forward or reverse.

It should be noted that, in some other embodiments, the guide block 6 can also be fixed in the receiving groove 12 in the circumferential direction, and can only move up and down along the receiving groove 12, and then when the knob 5 rotates relative to the guide block 6, the guide block 6 The circumferential limit is in the receiving groove 12 .

FIG. 14 is an assembly diagram of the knob 5 in FIG. 4 . FIG. 15 is a structural schematic diagram of the assembled knob 5 in FIG. 14 . FIG. 16 is a schematic structural view of the knob 5 in FIG. 15 in a locked state.

Please refer to FIG. 14 to FIG. 16 , and in combination with FIG. 2 to FIG. 4 , the rubber sleeve 7 is made of flexible material, and is sheathed on the outer peripheral wall of the guide block 6 . At the same time, a limit ring 602 arranged in a circumferential direction protrudes from the peripheral wall of the guide block 6 , and the limit ring 602 is located on the lower side of the rubber sleeve 7 . Therefore, when the fitting portion 601 is inserted into the assembly hole 32 , the rubber sleeve 7 is sandwiched between the limiting ring 602 and the bottom surface of the mounting base 3 .

In some embodiments, the rubber sleeve 7 is in a ring-shaped structure, and correspondingly, the portion of the guide block 6 corresponding to the rubber sleeve 7 is in a cylindrical structure.

In some embodiments, the guide block 6 is movably disposed in the receiving groove 12 and can move vertically in the receiving groove 12 up and down. Specifically, when the fitting portion 601 is fitted into the fitting hole 32 , the fitting portion 601 can move axially along the fitting hole 32 . Therefore, when the shaft pin 52 of the knob 5 rotates relative to the guide block 6 along the adjustment surface 64, the guide block 6 can gradually approach the knob 5, so that the guide block 6 moves upward in the axial direction, and the limit ring 602 gradually approaches the mounting seat 3, so that the limit ring 602 can squeeze the rubber sleeve 7, so that the rubber sleeve 7 is deformed due to extrusion, and then the guide block 6 and the knob 5 are relatively squeezed and fixed together with the mounting seat 3 and the upper hinge 4. , and finally realize the clamping and fixing of the mounting base 3 and the upper hinge 4 .

It should be noted that, in some other embodiments, the guide block 6 can also be fixedly arranged in the receiving groove 12 .

Please refer to Fig. 1 and Fig. 2, the hinge cover 9 is arranged on the top of the box body 1, and is used to cover the hinge 4, the mounting seat 3 and the knob 5, so that the appearance of the top of the box body 1 is neat and beautiful.

Please refer to Figures 14 to 16, and in combination with Figures 2 to 4, one of the installation methods of the upper hinge mechanism 30 is roughly as follows: first place the guide block 6 in the receiving groove 12; then fix the mounting base 3 on the box body 1 First, make the fitting part 601 and; then clamp and install the upper hinge 4 on the mounting base 3; align the shaft pin 52 of the knob 5 with the pin hole 62, as shown in Figure 14, and then insert the knob 5 downward Installed in the guide block 6, as shown in Figure 15; finally rotate the knob 5, so that the shaft pin 52 of the knob 5 rotates along the adjustment surface 64, and then squeeze the guide block 6 to make the distance between the knob 5 and the guide block 6 gradually and tighten the upper hinge 4 on the installation seat 3 by squeezing the rubber sleeve 7, and clamp and fix the upper hinge 4 and the installation seat 3 between the knob 5 and the guide block 6, as shown in Figure 16 .

In the process of locking the upper hinge 4, when the knob 5 is inserted into the inside of the guide block 6 and rotated about 90 degrees, the shaft pin 52 of the knob 5 can be rotated to the plane part 642 and aligned with the stop in the guide block 6. The blocking wall 643 is against each other, and the upper hinge 4 and the mounting base 3 are clamped and fixed between the knob 5 and the guide block 6 . It should be noted that the rotation angle can be adjusted by adjusting the positions of the adjustment surface 64 and the stop wall 643 .

In the process of unlocking the upper hinge 4, it is only necessary to reversely rotate the knob 5 so that the shaft pin 52 of the knob 5 is aligned with the pin hole 62, so that the knob 5 can be pulled out from the guide block 6, and then the upper hinge 4 can be pulled out from the guide block 6. Remove it from the mounting base 3. And because the installation seat 3 is fixed on the box body 1 by screws, there is no need to disassemble it, so the installation position of the upper hinge 4 is unique. When the user installs the door body 2 again, the installation of the door body 2 will not be skewed, and the installation operation is simple fast.

FIG. 17 is another assembly diagram of the upper hinge mechanism 30 in FIG. 2 . FIG. 18 is a schematic diagram of disassembly and assembly of the upper hinge 4 in FIG. 2 .

Please refer to FIG. 17 and FIG. 18 , in some embodiments, another assembly method of the upper hinge mechanism 30 is roughly as follows: the upper hinge 4 can be clamped and installed on the mounting base 3 first, and then through the knob 5 and the guide block 6 Relatively lock the upper hinge 4 and the mounting seat 3, so that the mounting seat 3, the upper hinge 4, the knob 5, the guide block 6 and the rubber sleeve 7 are installed as a whole, as shown in Figure 17; then lock the mounting seat 3 with screws Fixed on the top surface of the box body 1, the installation of the upper hinge mechanism 30 can be completed, as shown in FIG. 17 . When unlocking, the upper hinge 4 can be disassembled by rotating the knob 5 in the opposite direction, as shown in FIG. 18 .

Based on the above technical solutions, the embodiments of the present invention have at least the following advantages and positive effects:

In the refrigerator of the embodiment of the present invention, the upper hinge mechanism 30 is used to connect the box body 1 and the door body 2. At the same time, in the upper hinge mechanism 30, the mounting seat 3, the upper hinge 4, the knob 5 and the guide block 6 are used to cooperate, and the mounting seat 3 It is installed on the top of the box body 1, which is convenient for the installation of the upper hinge 4, and can improve the installation strength of the upper hinge 4; the upper hinge 4 is detachably installed directly above the mounting seat 3, and at the same time cooperates with the rotation of the knob 5 and the guide block 6 Clamped on the upper and lower sides of the mounting base 3 and the upper hinge 4, and then the upper hinge 4 and the mounting base 3 are clamped and fixed between the knob 5 and the guide block 6, so that the upper hinge 4 is fixed on the mounting base 3, thereby facilitating Upper hinge 4 is disassembled. In the process of disassembling the door body 2, the upper hinge 4 can be disassembled only by turning the knob 5 in the opposite direction, without disassembling the mounting base 3, and without disassembling and fixing the screws, which is beneficial to save disassembly and assembly time during the transportation process, and enhance the Disassembly efficiency and delivery efficiency.
