[0043] Combination Figure 1 and Figure 2 As shown, the hinge of this application includes a first hinge seat 1 for mounting on a door leaf, a second hinge seat 2 for mounting on a door frame, and a connecting assembly 3 hinged between the first hinge seat 1 and the second hinge seat 2; the height of the second hinge seat 2 is less than the height of the first hinge seat 1.

[0044] By reducing the height of the second hinge seat 2, it is possible to avoid excessively deep grooves in the door frame, thus preventing adverse effects on the structural strength of the door and improving overall strength and safety.

[0045] Combination Figure 3 As shown, one end of the connecting component 3 is hinged to a first adjusting component 4, which is connected to the first hinge seat 1; the other end of the connecting component 3 is hinged to a second adjusting component 5, which is connected to the second hinge seat 2; the first adjusting component 4 includes a buffer 401 for providing motion buffering resistance to the connecting component 3, and the buffer 401 is hinged to the connecting component 3.

[0046] By setting adjustment components at both ends of the connecting component 3, the position of the hinge can be precisely adjusted.

[0047] Combination Figure 5 As shown, in this embodiment, the connecting component 3 includes a first connector 31, a second connector 32 and a third connector 33.
