Description

a hidden hinge

technical field

The utility model relates to the technical field of door and window hardware accessories, in particular to an invisible hinge.

Background technique

Currently commonly used hinges are usually composed of a rotating shaft and two leaf hinges. The rotating shaft of this kind of hinge will be exposed outside and it is not easy to be decorated. After decoration, the hinge shaft will be exposed, which looks uncoordinated. Use this hinge in addition when the door and window are opened, there will be a larger gap between the door and the door frame, and the sealing performance is poor.

Contents of the invention

The purpose of the present invention is to overcome the deficiencies of the prior art and provide an invisible hinge capable of hiding its rotating shaft.

In order to achieve the above object, the technical solution adopted in the utility model is:

An invisible hinge, including a fixed leaf for connecting a door frame and a movable leaf for connecting a door leaf, the fixed leaf and the movable leaf are hinged through a rotating shaft, and the fixed leaf includes a hinge that can cooperate with the door frame to form a hidden space for the rotating shaft The door frame connector is provided with a fixed leaf hinge installation part inside the door frame connector, and at the same time, there is a gap for the movable leaf to rotate on the door frame connector; The rotating part is hinged with the door frame connecting part and extends to the outside of the hidden space of the rotating shaft through its gap to connect with the door leaf connecting part.

Further, the rotating member is bent to form at least two sections, the first and last sections of which are hinged to the door frame connector and connected to the door leaf connector respectively.

Further, the width of the notch of the door frame connecting part matches the width of the rotating part.

Further, the door leaf connecting piece is provided with a waist-shaped hole, and is connected with the rotating piece in a bolted manner.

The beneficial effects of the utility model are: the invisible hinge of the utility model, the door frame connecting part can cooperate with the door frame to be installed to form a hidden space for the rotating shaft, and a fixed hinge rotating shaft installation part is arranged on the inner side of the door frame connecting part, so that the hinge The rotating shaft can be hidden in the hidden space of the rotating shaft; at the same time, there is a notch on the door frame connector for the rotation of the moving page, so that the normal rotation between the moving page and the fixed page can still be realized under the premise that the rotating shaft is hidden. After adopting the above structure, the utility model can hide the rotating shaft to improve the appearance of the product, and at the same time, it is convenient to install and adjust the door leaf. It cannot be pried from both sides to ensure safety, and the cost is low, which is 20% lower than the commonly used hinges now. about.

Detailed ways

The technical solution claimed by the utility model will be further described in detail in conjunction with the accompanying drawings and specific embodiments.

Referring to Figures 1-4, in this embodiment, the invisible hinge includes a fixed leaf 1 and a moving leaf 2, and the fixed leaf 1 and the moving leaf 2 are hinged through a rotating shaft 3. Among them, the fixed page 1 includes a door frame connector 11 for connecting with the door frame 5, the door frame connector 11 can cooperate with the door frame 5 to be installed to form a shaft hidden space 4, in this embodiment, the door frame connector 11 is installed on a door with a notch. On the door frame 5 of the structure; the door frame connector 11 is an "L" shaped two-section structure, one of which is installed on the notch of the door frame 5 to close the notch to form the hidden space 4 of the rotating shaft, and the other part is to the inner direction (that is, the hidden space of the rotating shaft 4 inside) is extended and formed with a fixed hinge shaft installation part 112, so that the hinge hinge 3 is located in the hinge hidden space 4; at the same time, a gap 111 for the movable hinge 2 to rotate is opened on the door frame connector 11. The main function of the door frame connector 11 connector is to connect the door frame 5 and cooperate with the door frame 5 to form the hidden space 4 of the rotating shaft. Its specific structure is related to the structure of the door frame 5 to be installed and the installation positions of the two. The position is located on the notch structure of the door frame 5, so only one section of the door frame connector 11 constitutes one side of the shaft hidden space 4, and the installation position of the door frame 5 provides three sides for the shaft hidden space 4; and so on, if the door frame 5 If the installation position can provide two sides for the shaft hidden space 4, then the door frame connector 11 needs to provide two sides.

The moving leaf 2 includes a rotating part 21 and a door leaf connecting part 22. In this embodiment, the rotating part 21 is bent and formed into a two-stage structure, and a mounting seat for the rotating shaft 3 of the moving leaf 2 is formed on one of the sections, through which the rotating shaft 3 connects with the door frame. 11 is hinged, and this section also extends to the outside of the shaft hidden space 4 through its gap 111; the other section is connected with the door leaf connector 22 outside the shaft hidden space 4. In this embodiment, the door leaf connector 22 is provided with a waist-shaped hole, and is connected to the door leaf 6 by means of bolt connection to adjust the position of the door leaf connector 22; the door leaf connector 22 is also bent to form a two-stage structure, One of them is connected with the rotating part 21, and the other is connected with the door leaf 6; the specific structure of the door leaf connector 22 is mainly determined by the connection position of the door leaf connector 22 on the door leaf 6, and the door leaf connector is adjusted according to the change of its connection position during implementation. 22 to adjust the specific structure.

After adopting the above structure, the invisible hinge of this embodiment can hide the rotating shaft to improve the appearance of the product, and at the same time, it is convenient to install and adjust the door leaf. The page is about 20% lower.

The above-mentioned embodiments are only preferred embodiments of the present utility model, and are not intended to limit the present utility model in any form. Any person familiar with the art, without departing from the scope of the technical solution of the present utility model, can make use of the technical content disclosed above to make more possible changes and modifications to the technical solution of the utility model, or modify it to be equivalent to the equivalent change. Example. Therefore, all equivalent and equivalent changes made according to the idea of the utility model that do not deviate from the technical solution of the utility model shall be covered within the protection scope of the utility model.
