The technical problem to be solved by the utility model is that the existing frame fan is relatively flush Steel door It is difficult to ensure that the frames and leaves are completely flush, and some auxiliary structures often protrude slightly from the surface of the door frames or leaves, resulting in aesthetic and texture defects. Especially in Hinge There are some deficiencies in the design of and on the external surface.
The utility model adopts the following technical scheme:
A frame leaf flush type steel door structure comprises a door frame 1, a door leaf 2, and a concealed hinge 3; The corresponding position of the door frame 1 and the hinge is a hollow structure, in which a concealed hinge 3 is fixedly arranged, and the concealed hinge 3 is fixedly connected with the door leaf 2; The door frame and the outside of the door leaf are attached with a facing, and the external surface of the facing is flush.
The beneficial effects of the utility model are:
1) Hidden hinges are hidden inside the hollow door frame, ensuring that the frame and leaf are completely flush.
2) Decorations are set on the frame and fan at the same time to avoid aesthetic and texture defects.
3) Through reasonable selection Hardware accessories . Cleverly optimize the frame leaf overlapping structure to achieve the flatness of the door body surface. In engineering applications wall , door frame and door leaf are in the same plane without cutting off the decorative effect.
4) In the closed state, the surfaces of both sides of the door leaf and door frame are flush, and there is no case that the door frame is higher than the surface of the door leaf, which provides a basis for the overall external decoration.
5) Paste Sealing strip The design of the door leaf and frame is ingenious seal up At the same time, it does not affect the flush effect of the frame and fan.
The concealed hinge of the utility model is concealed in the hollow door frame, which ensures that the frame and leaf are completely flush; At the same time, the frame and fan are equipped with veneers to avoid aesthetic and texture defects; Through reasonable selection of hardware fittings and ingenious optimization of the frame and leaf overlapping structure, the flatness of the door body surface is achieved. In engineering applications, the wall, door frame and door leaf are complete and unbroken in the same plane; In the closed state, the surfaces of both sides of the door leaf and door frame are flush, and there is no case that the door frame is higher than the surface of the door leaf, which provides a foundation for the overall external decoration; The design of the adhesive sealing strip is ingenious, which ensures the tightness of the door leaf and the door frame, and does not affect the flush effect of the frame leaf.
The above is the preferred embodiment of the utility model. On this basis, ordinary technicians in the field can also make various transformations or improvements. Without departing from the general concept of the utility model, these transformations or improvements should also fall within the scope of protection required by the utility model.
