[0042] This embodiment also provides a split door leaf hinge seat 3 and a door frame hinge seat 4, and the specific structures are as follows:

[0043] As Figures 7-11 shown, the door leaf hinge seat 3 includes a first hinge seat body 22 and two first adjusting blocks 23. The first hinge seat body 22 has a first T-shaped notch groove. The two first adjusting blocks 23 are installed at both ends of the two first T-shaped notch grooves. The space between the two first adjusting blocks 23 forms a first installation notch. The two first adjusting blocks 23 are fixedly connected by a first connecting rod 24. Two first track guide grooves 6 are respectively arranged on the opposite side surfaces of the two first adjusting blocks 23, and two first pin holes are respectively arranged on the opposite side surfaces of the two first adjusting blocks 23.

[0044] Both ends of the first T-shaped notch groove are provided with first threaded holes 25. Each first adjusting block 23 is provided with an oblong adjusting hole 26. The two first adjusting blocks 23 are respectively installed at both ends of the first T-shaped notch groove through fixing bolts 27, and the oblong adjusting hole 26 is correspondingly arranged with the first threaded hole 25. The fixing bolt 27 passes through the oblong adjusting hole 26 and is threadedly connected in the first threaded hole 25.

[0045] In this embodiment, the left and right gaps of the two first adjusting blocks 23 in the first T-shaped notch groove can be finely adjusted. Specifically, loosen the fixing bolt 27, and then the two first adjusting blocks 23 can be moved. The fixing bolt 27 moves relatively in the oblong adjusting block. When adjusted to the appropriate position, tighten the fixing bolt 27 again, and use the head of the fixing bolt 27 to press and fix the first adjusting block 23.

[0046] The doorframe hinge seat 4 includes a second hinge seat body 28 and two second adjusting blocks 29. The second hinge seat body 28 has a second T-shaped notch groove 30. The two second adjusting blocks 29 are installed at both ends of the two second T-shaped notch grooves 30. A second installation notch is formed in the space between the two second adjusting blocks 29. The two second adjusting blocks 29 are fixedly connected by a second connecting rod 31. Two second track guide grooves 8 are respectively arranged on the opposite side surfaces of the two second adjusting blocks 29, and two second pin holes are respectively arranged on the opposite side surfaces of the two second adjusting blocks 29.

[0047] The two second adjusting blocks 29 are respectively installed at both ends of the second T-shaped notch groove 30 through adjusting studs 33;

[0048] The adjusting stud 33 is rotatably installed at the end of the second T-shaped notch groove 30, and an axial limiting structure is arranged on the adjusting stud 33 to limit its axial position. A second threaded hole 32 is formed in each of the two second adjusting blocks 29. The adjusting stud 33 is threadedly connected in the second threaded hole 32. An internal hexagonal groove is arranged at the end of the adjusting stud 33, and the arrangement of the internal hexagonal groove facilitates the use of an internal hexagonal wrench to screw and install.

[0049] The axial limiting structure is a retaining ring 34 and a flat washer 35. The retaining ring 34 and the flat washer 35 are fixed to the lower part of the adjusting stud 33. The flat washer 35 is located below the retaining ring 34. A round hole 36 is arranged at the end of the second T-shaped notch groove 30. The adjusting stud 33 is inserted into the round hole 36, and the round hole 36 is between the retaining ring 34 and the flat washer 35.

[0050] In this embodiment, the vertical height of the two second adjusting blocks 29 in the second T-shaped notch groove 30 can be finely adjusted. Specifically, when the adjusting stud 33 is screwed, since the adjusting stud 33 is limited in the round hole 36 at the end of the second T-shaped notch groove 30, the height of the adjusting stud 33 cannot be changed. The adjusting stud 33 is also threadedly connected to the second adjusting block 29. Therefore, the rotation of the adjusting stud 33 will inevitably drive the second adjusting block 29 to move, and finally change the height position of the second adjusting block 29 in the second T-shaped notch groove 30.
