[0036] Embodiment 1, as Figure 1 , 2 As shown in Figures 3, 4, 5, 6, and 7, when installing the hinge, first make grooves at the door and the door frame, then put the protective frame 9 in the grooves, and then put the adjusting right-angle block B4 and the adjusting right-angle block A3 inside the protective frame 9 to protect them. If the adjusting piece 5 and the fixed block 2 cannot fit tightly in the installation groove, first rotate the rotating rod 17, and then drive the rotating shaft 13 and the gear 12 to rotate. During the rotation of the gear 12, the two sets of racks 15 are driven to move closer or farther away, and then the telescopic amount of the telescopic rod 11 is adjusted, thereby adjusting the distance between the two sets of adjusting right-angle blocks B4 and the distance between the two sets of adjusting right-angle blocks A3, so that the fixed block 2 and the adjusting piece 5 can be completely fitted in the installation groove, and then the adjusting right-angle block B4 and the adjusting right-angle block A3 are pushed away from or closer to each other according to the width of the door, and when adjusted to the most suitable position, they are fixed with bolts.

[0037] Embodiment 2, as Figure 1 , 2 As shown in Figures 3, 4, and 5, after the hinges are installed, the door leaf is opened and closed multiple times. If the door cannot be completely closed during the opening and closing process, the bolt on the right-angle block A3 is rotated clockwise to adjust the right-angle block A3 so that the right-angle block A3 slides along the fixed block 2, thereby increasing the distance of the door gap. If the door gap is too small, the bolt on the right-angle block A3 is rotated counterclockwise to reduce the distance of the door gap, so that the door can be completely closed. If the door hits the door frame during the closing process and cannot be closed, the bolt on the right-angle block B4 is rotated clockwise to adjust the extension distance of the door, thereby solving the problem that the door cannot be closed due to hitting the door frame.

[0038] Working principle: When installing the hinge, first make a groove at the door and the door frame, then put the protective frame 9 in the groove, and then put the adjusting right-angle block B4 and the adjusting right-angle block A3 inside the protective frame 9 to protect it. If the adjusting piece 5 and the fixed block 2 cannot fit tightly in the installation groove, first rotate the rotating rod 17, and then drive the rotating shaft 13 and the gear 12 to rotate. During the rotation of the gear 12, the two sets of racks 15 are driven to move closer or farther away, and then the telescopic amount of the telescopic rod 11 is adjusted, thereby adjusting the distance between the two sets of adjusting right-angle blocks B4 and the distance between the two sets of adjusting right-angle blocks A3, so that the fixed block 2 and the adjusting piece 5 can be completely fitted in the installation groove, and then the adjusting right-angle block B4 and the adjusting right-angle block A3 are pushed away from or closer to each other according to the width of the door, and when adjusted to the most suitable position, they are fixed with bolts;

[0039] After the hinges are installed, the door leaf is opened and closed several times. If the door cannot be completely closed during the opening and closing process, the bolt on the right-angle block A3 is rotated clockwise to adjust the right-angle block A3 so that the right-angle block A3 slides along the fixed block 2, thereby increasing the distance of the door gap. If the door gap is too small, the bolt on the right-angle block A3 is rotated counterclockwise to reduce the distance of the door gap, so that the door can be completely closed. If the door hits the door frame during the closing process and cannot be closed, the bolt on the right-angle block B4 is rotated clockwise to adjust the extension distance of the door, thereby solving the problem that the door cannot be closed due to hitting the door frame.

[0040] Finally, it should be noted that the above content is only used to illustrate the technical solution of the present invention, rather than to limit the scope of protection of the present invention. Simple modifications or equivalent substitutions of the technical solution of the present invention by ordinary technicians in this field do not deviate from the essence and scope of the technical solution of the present invention.
