Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-3, the silent hinge for doors and windows comprises a left hinge 1, a right hinge 2 and a middle shaft 3 fixedly assembled with the left hinge 1 and the right hinge 2, wherein a left mounting position 4 and a right mounting position 5 are integrally arranged in the middle of a mounting end of the left hinge 1 and at two ends of a mounting end of the right hinge 2 correspondingly, a silica gel air column 6 is arranged inside the left mounting position 4, and bearings 7 for bearing the middle shaft 3 are arranged at two ends of the left mounting position 4 corresponding to the silica gel air column 6;

the right installation position 5 is internally provided with an oil immersion layer 8, a silica gel ring 9 is correspondingly arranged in the oil immersion layer 8, the installation end of the middle shaft 3 sequentially penetrates through the silica gel ring 9 and the bearing 7 to be arranged at the tail end of the right installation position 5, and the right installation position 5 is provided with a fixing position 10 corresponding to the tail end of the middle shaft 3.
