Description

Technical Field

[0001] This utility model relates to the field of hinges, and in particular to an oil-free, silent, quick-install hinge. Background Technology

[0002] Existing ordinary hinges mainly consist of two parts: a first hinge body and a second hinge body. The first hinge body and the second hinge body are connected by a connecting post, which is exposed on the outside and is not aesthetically pleasing. Therefore, there is a need for a hinge with a simpler structure, a more stable connection, and a more beautiful appearance. Utility Model Content

[0003] The main purpose of this utility model is to provide an oil-free, silent, quick-install hinge with a relatively simple structure, more stable connection, and more beautiful appearance.

[0004] This utility model proposes an oil-free, silent, quick-install hinge, comprising a first hinge body, a second hinge body, a first rotating connecting post, and a second rotating connecting post;

[0005] The first hinge body has a first fixing post and a second fixing post on the top and bottom of the rear side, and the first fixing post and the second fixing post have a first through hole and a second through hole. The second hinge body has a third fixing post in the middle of the rear side, and the third fixing post has a third through hole.

[0006] A first fixing post connecting groove is provided on the top inner side of the first through hole, and a second fixing post connecting groove is provided on the bottom inner side of the second through hole. A first connecting block is provided on the top side of the first rotating connecting post. The first rotating connecting post is snapped into the first fixing post by the cooperation of the first connecting block and the first fixing post connecting groove and fixedly connected by welding. A second connecting block is provided on the bottom side of the second rotating connecting post. The second rotating connecting post is snapped into the second fixing post by the cooperation of the second connecting block and the second fixing post connecting groove and fixedly connected by welding.

[0007] The ends of the first and second rotating connecting posts extend into the third through hole of the third fixed post, thereby allowing the second hinge body to be rotatably connected to the first hinge body.

[0008] Preferably, the first hinge body is provided with a first hinge body connecting groove, and the second hinge body is hidden in the first hinge body connecting groove.

[0009] Preferably, the first hinge body is provided with a plurality of first hinge body connection holes, and the first hinge body is connected to the door frame through the first hinge body connection holes.

[0010] Preferably, the second hinge body is provided with a plurality of second hinge body connection holes, and the second hinge body is connected to the door through the second hinge body connection holes.

[0011] Preferably, it also includes a first connecting bearing and a second connecting bearing. A third fixing post connecting groove is provided on the top and bottom of the inner side of the third through hole. The first connecting bearing and the second connecting bearing are respectively limited in the two third fixing post connecting grooves. By setting the first connecting bearing and the second connecting bearing, the rotation between the first hinge body and the second hinge body can be made smoother.

[0012] The beneficial effects of this oil-free, silent, quick-install hinge are as follows:

[0013] 1. Compared with conventional single connecting columns, this patent uses a first rotating connecting column and a second rotating connecting column, and hides the first rotating connecting column and the second rotating connecting column inside the first fixed column and the second fixed column, thereby improving the aesthetics of the appearance and the connection stability after welding.

[0014] 2. By setting the first connecting bearing and the second connecting bearing, the rotation between the first hinge body and the second hinge body can be made smoother. Attached Figure Description
