Description

Technical Field

[0001] The present invention relates to the technical field of hinges, in particular to a hinge with a wire-passing structure. Background Art

[0002] A hinge is an assembly hardware used for rotational connection between movable parts. It usually consists of two parts that rotate relative to each other. By installing the two parts on two relatively movable workpieces respectively, the hinge can be used to achieve a rotational connection, thereby improving the strength of the rotational connection and the precision during the opening and closing process.

[0003] However, in some special cases, a circuit needs to be laid between two rotating movable parts so as to achieve the effect of electrically connecting the components on the two movable parts. The current mainstream practice on the market is to set a cavity inside the main rotating shaft of the hinge and install the wire inside the cavity, so that the two sides of the hinge will not interfere with the wire inside the wire guide when rotating. However, in actual application, it is found that when the wires are passed through the main rotating shaft, the wires will be close to each other, and the number of wires passed is limited by the size of the inner diameter of the wire passer. Therefore, most of the wires on the market are low-voltage wires. At the same time, during the process of rotating opening and closing, friction is likely to occur between multiple wires, resulting in wear and noise, which reduces the service life of the wires. For this purpose, a hinge with a wire passing structure is specially provided. Summary of the invention

[0022] The embodiment of the present application solves the problem that the number and diameter of wires of the mainstream hinges with wire passing structures currently on the market are limited by the method of passing wires through the rotating axis of the hinge. At the same time, during the process of rotation and opening and closing, friction is likely to occur between multiple wires, resulting in wear and noise, which reduces the service life of the wires.

[0023] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0024] The embodiment of the present invention discloses a hinge with a wire-passing structure.

[0032] During installation, by rotating the screws inside the front and rear adjustment station 313, the front and rear adjustment plates 315 are moved forward and backward inside the front and rear adjustment station 313 to adjust the front and rear spacing between the door body and the door frame during installation. At the same time, by loosening the screws in the height adjustment slot 324, the connecting seat 321 is moved up and down to adjust the installation height of the door body. By loosening the screws in the left and right adjustment station 326, the left and right adjustment members 327 are moved laterally in the left and right adjustment station 326 to adjust the effective position of the door body during installation, thereby achieving three-dimensional adjustment during the door body installation process, thereby ensuring the assembly accuracy after installation and reducing the fault tolerance rate during gap and slotting operations.

[0033] The hinge box 1 comprises a first box body 11 and a second box body 12 . A raised baffle 13 is disposed on opposite sides of the first box body 11 and the second box body 12 . An assembly opening 14 is disposed on the back side of the second box body 12 .

[0036] Working principle: The device opens a wire threading groove 16 on the back of the hinge box 1, selects a flexible wire 41 as the main wire of the wire passer 4, and extends the two ends of the flexible wire 41 from the inside of the hinge box 1 through the wire threading groove 16 to the outside, and then installs wiring terminals 43 at both ends of the flexible wire 41, and fixes the wiring terminals 43 to the outer wall of the hinge box 1 through the mounting plate 42. It can be installed on the back or both sides. At the same time, the main body of the flexible wire 41 fits the inner wall of the rotating connection part 2, so that after the hinge box 1 is installed on the door body and the door frame, the flexible wire 41 is passed through the inside of the hinge box 1 to play a role in aesthetic shielding.
