Description

a hidden hinge

【Technical field】

The utility model relates to the field of hinges, in particular to a hidden hinge.

【Background technique】

Hinges are often used to connect doors, windows and building materials to achieve open rivers. With the continuous change of architectural decoration concepts, people put forward higher requirements for the structural beauty and structural strength of such hinge connection structures. However, the current Hinge connectors are difficult to meet. Most of the hinge structures on the market are shaft-connected hinges. Using the hinge shaft connection method, the structural strength is low, and it cannot bear heavy doors, and it can only be applied to the shaft-connected joints of doors and windows, which lacks cushioning for the impact of opening and closing. ability, and the hinges can be seen on the outer surface of the door, which lacks aesthetics.

【Content of utility model】

The purpose of the utility model is to overcome the above-mentioned shortcomings in the prior art, and provide a concealed hinge with convenient installation, high connection strength and strong load-bearing capacity.

The utility model is realized through the following technical solutions:

A hidden hinge, including a first hinge, a second hinge and a hinge assembly, the hinge assembly includes a first connecting piece and a second connecting piece, the first hinge is provided with a first chute, the second The second hinge is provided with a second chute, one end of the first connecting piece is hinged on the first hinge, and the other end is slidably connected with the second chute through the first rotating shaft, and one end of the second connecting piece is hinged on the On the second hinge, the other end is slidingly connected to the first chute through the second rotating shaft, and the first connecting piece and the second connecting piece are installed side by side on the first hinge and the second hinge, so that the first hinge It is connected with the second hinge, and three-fifths of the first connecting part and the second connecting part are connected through a hinge shaft and rotate around the hinge shaft.

Preferably, the first connecting piece and the second connecting piece are in an obtuse “L” shape.

Preferably, the diameters of the first rotating shaft and the second rotating shaft are consistent with the widths of the first sliding groove and the second sliding groove.

Preferably, a gasket is sheathed on the hinge shaft, and the gasket is arranged between the first connecting piece and the second connecting piece.

Preferably, both the first hinge and the second hinge are provided with several fixing holes.

The beneficial effects of a hidden hinge of the utility model are as follows:

The utility model discloses a concealed hinge. The utility model is installed on the door frame through the installation hole on the hinge by opening an installation opening on the door frame. Through the multi-axis linkage and sliding of the hinge assembly, the hinge assembly can be completely embedded in the first hinge and the second hinge, which is not only conducive to the installation of the hinge, but also can not be seen outside the door frame after installation. page, to achieve a better installation effect. Moreover, the twisted components are all hinged with the first hinge and the second hinge, which improves the strength of the connection structure and can bear heavier doors and windows.

The conception, specific structure and effects of the present utility model will be further described below in conjunction with the accompanying drawings, so as to fully understand the purpose, features and effects of the present utility model.

【Detailed ways】

A kind of concealed hinge of the utility model is further described below in conjunction with accompanying drawing:

In order to facilitate the understanding of the utility model, the utility model will be described in more detail below in conjunction with the accompanying drawings and specific embodiments.

As shown in the figure, a concealed hinge includes a first hinge 1 , a second hinge 2 and a hinge assembly 3 . The hinge assembly 3 includes a first connecting piece 31 and a second connecting piece 32, the first hinge 1 is provided with a first sliding groove 11, the second hinge 2 is provided with a second sliding groove 21, and the first hinge 2 is provided with a second sliding groove 21. One end of the connecting member 31 is hinged on the first hinge 1 , and the other end is slidably connected to the second sliding slot 21 through the first rotating shaft 311 . One end of the second connecting member 32 is hinged on the second hinge 2 , and the other end is slidably connected to the first sliding slot 11 through the second rotating shaft 321 . The first connecting member 31 and the second connecting member 32 are installed side by side on the first hinge 1 and the second hinge 2 to connect the first hinge 1 and the second hinge 2 . Three-fifths of the first connecting member 31 and the second connecting member 32 are connected through the hinge shaft 4 and rotate around the hinge shaft 4 . The best implementation mode of this embodiment is: the first connecting part 31 and the second connecting part 32 form an "L" shape with an obtuse angle α. By setting the obtuse angle α of the first connecting piece 31 and the second connecting piece 32 to 131°, the glass door is opened until the angle between the glass door and the door frame is 90°. The utility model hides the hinge assembly 3 ingeniously in the hinge by sliding and rotating at the same time, which not only increases the beautiful structure, but also improves the structural strength, so that the hinge can bear heavier doors.

Specifically, the diameters of the first rotating shaft 311 and the second rotating shaft 321 are consistent with the widths of the first sliding slot 11 and the second sliding slot 21 . In this way, during the practical process, the glass door will not shake and produce abnormal noise during opening and closing, which will affect the user experience.

More specifically, a washer 41 is sheathed on the hinge shaft 4, and the washer 41 is arranged between the first connecting member 31 and the second connecting member 32 to prevent the first connecting member 31 and the second connecting member 32 from Rubbing against each other while turning, causing damage.

When in use, with the switch of the glass door, the switch of the first hinge 1 and the second hinge 2 is driven, because the first hinge 1 is fixedly connected with the door frame through the connecting hole 5, and is partially arranged in the door frame. Therefore, the first rotating shaft 311 of the first connecting member 31 will slide and rotate in the second slide groove 21 on the second hinge 2 , and the other end of the first connecting member 31 is hinged with the first hinge 1 . The second rotating shaft 321 of the second connecting member 32 will slide and rotate in the first chute 11 of the first hinge 1 , and the other end of the second connecting member 32 is hinged to the second hinge 2 . The first connecting member 31 and the second connecting member 32 are connected by the hinge shaft 4, so that the coordination of the connecting movement of the hinge assembly 3 is better, and the structural strength is better.

The hinge with the above structure can well hide the hinge assembly 3 in the hinge. By installing the hinge in the door frame, when the door is closed, no trace of the hinge can be found from the inside to the outside. , the second hinge 2 of the glass door makes the first connecting part 31 and the second connecting part 32 simultaneously linked, thereby opening the door.

Preferred embodiments of the utility model are provided in the accompanying drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described in this specification. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present utility model more thorough and comprehensive.
