Description

Hidden hinge structure

The present invention is to provide a structure of a hidden hinge, especially a structure that uses a two-stage rotation design to improve the overall look, airtightness, waterproof performance and hinge support force, and has a wide range of applications.

Press, hinge, also known as hinge, is a mechanical device used to connect two solid bodies so that they can be rotated. Hinges are usually used to install on doors or windows.

At present, most of the opening and closing devices such as doors and windows on the market belong to the application of hinges. They use the concept of a segment of the center of rotation to allow the user to rotate while pushing and pulling. The opening and closing device will gradually rotate and rotate during the pushing process. After reaching a certain angle, the concept of folding doors and folding windows is reached. Among them, the opening and closing device can be divided into two forms: "a section of turning center is located outside the door leaf" and "a section of turning center is located inside the door leaf". The opening and closing device with a section of turning center located outside the door leaf is used. It is not easy to get stuck on the door frame or the airtight strip, and can pressurize and press the airtight strip to strengthen the airtight and waterproof effect. A section of turning center is set in the door leaf opening and closing device. When moving and closing, the hinge will not be exposed to the outside of the door leaf, so that it will not damage the appearance, and it can also reduce the supporting force of the hinge. In addition, the door wheel and track that drive the hinge can also be hidden above and below the door leaf. To enhance the look and feel.

However, when the above-mentioned opening and closing device is in use, the following problems and deficiencies remain to be improved:

First, a section of the center of rotation is set in the door leaf. No matter where it is located in the door leaf, the turning radius will be too large, which will cause the door leaf to be stuck on the door frame or airtight strip when the door leaf is turning. Usually the way of leaving the door gap is adopted. However, the design of the door seam makes the aesthetic effect poor. At the same time, it is impossible to pressurize and press the airtight strip, which makes the airtight and waterproof effect poor.

Second, a section of the center of rotation is set outside the door leaf, when the door leaf is opened or closed to 90 degrees, The hinge will be exposed to the outside of the door leaf. In addition to the insufficient support of the hinge, the aesthetic effect of the hidden hinge will not be achieved. Moreover, the door wheel and track that drive the hinge to rotate will also be exposed above and below the door leaf when the door leaf is closed. Square, not only destroys the beauty, but also causes the problem of poor balance of the door leaf.

Therefore, how to solve the above-mentioned conventional problems and deficiencies is the direction that the applicant of the present invention and the related manufacturers engaged in this industry urgently want to study and improve.
