[0002] The door panels of the door body are rotated and assembled through a two-fold hinge structure to realize the opening and closing actions. At present, the function of ordinary hinges is relatively single, and generally they can only connect two parts of an object and enable them to move. As the external display screens of home appliances become more and more popular, the number of cables used is increasing. The traditional method of laying cables indoors is generally to directly drill holes in the walls of buildings for routing, which not only damages the buildings, but also is cumbersome to operate, affecting the overall aesthetics and concealment, making cable routing more troublesome and difficult.

[0016] One end of the two groups of hollow shafts 2 is plugged with a pin 10 for limiting the second connection block 5 . The second connection block 5 can be prevented from sliding on the surface of the hollow shaft 2 after being limited by the pin 10 .

[0017] The surfaces of the first hinge leaf 1 and the second hinge leaf 3 are both provided with mounting holes 11 , and the hinges are mounted through the mounting holes 11 on the surfaces of the first hinge leaf 1 and the second hinge leaf 3 .

[0018] The hinge central axis wire passing mechanism is completed by passing one end of the power cord 9 through the first wire hole 6 on the surface of the second connecting block 5 and the second wire hole 7 on the surface of the hollow rotating shaft 2, and then inserting the two groups of hollow rotating shafts 2 into the two groups of second connecting blocks 5 respectively, and passing one end of the power cord 9 passing through the second wire hole 7 through the third wire hole 8 on the surface of the first connecting block 4 and extending to the outside of the first hinge leaf 1, thereby completing the wiring. After the insertion is completed, the first connecting block 4 of the first hinge leaf 1 is placed between the two groups of second connecting blocks 5, and one end of the two groups of hollow rotating shafts 2 is respectively inserted into the top and bottom of the first connecting block 4.
