Flap concealed hinge

Abstract

The invention provides an opening covering type hidden hinge and provides a door shaft hinge installed at the position of a door shaft and completely hidden. The hinge comprises a square box type assembly and a page sheet assembly, wherein the square box type assembly is fixed to a door, and the page sheet assembly is fixed to a door frame; the square box type assembly and the page sheet assembly are connected in a hinged manner through a page sheet connection shaft arranged in the square box type assembly; the integral cross section of the square box type assembly and the page sheet assembly is a rectangle with a subsidence face; the side face of the square box type assembly sinks inwards compared with the side face of the page sheet assembly so that a dislocation face can be formed; a dislocation face can be formed between the door and the door frame after the door and the door frame are installed; a door leaf is provided with a covering opening so as to cover the door frame; and complete hiding of the hinge is achieved. The hinge can be completely hidden between the door and the door frame, the sealing, sound insulating and heat preserving effects of the door are improved, an anti-theft effect is achieved, installation is also convenient, appearance is attractive and elegant, an opening and closing angle is large, automatic closing can be performed, opening and closing are flexible and free of noise, and the service life is long.

Description

technical field [0001] The invention relates to the field of hinges, in particular to a completely concealed door hinge mounted on a door shaft. Background technique [0002] The door shaft hinge is one of the essential components of most doors and windows nowadays.

[0002] The door shaft hinge is one of the essential components of most doors and windows nowadays. It is mostly set at the connection between the door and the door frame, including two steel plates and a rotating shaft connecting the two steel plates. This hinge is also called a hinge. , has the advantages of simple structure, convenient installation and low cost, but its low strength, small load-bearing capacity, easy deformation, lax door frame closure, poor anti-theft performance and wear resistance, and limitations of disadvantages such as not being able to automatically close, make it only It can be used for ordinary light-duty doors, and its scope of application is small, and it is becoming more and more difficult to meet people's requirements for quietness, closure, safety, etc.

[0003] The existing hidden hinges have more and more complex structures. After installation, most of the structures can be hidden between the door and the door frame, with beautiful appearance and strong load-bearing capacity. However, according to the current installation habits, the gap between the door and the frame If it cannot be sealed well, there will still be large gaps. After installation, it is found that the gaps cannot be adjusted, etc. It still cannot meet people's requirements for the thermal insulation performance and sound insulation performance of the door, and it still needs continuous innovation and improvement.
