Description
Technical Field
[0001] This utility model belongs to the field of architectural decoration technology, specifically relating to a decorative hidden door that can be opened 180 degrees and stopped at any time. Background Technology
[0002] In modern interior design within the construction industry, concealed doors with decorative surfaces are gradually becoming a popular choice. The reasons behind this can be analyzed from multiple perspectives, reflecting the evolution of modern needs and design trends: In terms of space utilization, small spaces may focus more on saving space. Traditional doors require a large enough space to open and close, while hidden doors may have different opening methods, such as sliding or rotating doors, to save space.
[0003] In terms of functionality, hidden doors can conceal specific areas, such as storage rooms, secret rooms, or equipment rooms, while maintaining the tidiness of public areas. For spaces requiring privacy, such as studies or bedrooms, hidden doors offer better concealment. Privacy and security are also considerations. Some homeowners may wish to hide certain rooms to prevent them from being easily discovered by outsiders; hidden doors can increase security, especially in areas where valuables are stored.
[0004] In terms of personalized needs, the design of hidden doors can be unique, such as being made into bookshelves or mirrors, reflecting the owner's personality and creativity, and enhancing the interest of the space.
[0005] In terms of aesthetics, modern decoration may pursue a simple and unified design style. Concealed doors can hide the existence of doors, maintain the continuity of the wall, and look cleaner. For example, in minimalist or modern styles, reducing visual clutter is very important. Concealed doors for fire extinguisher boxes are a headache for designers nowadays. Moreover, current regulations require that the opening angle of concealed doors for fire extinguisher boxes be greater than 160 degrees. In actual construction, there may be situations where the upper and lower axes are not aligned, resulting in the concealed door not closing tightly, or automatically closing due to gravity after opening.
[0006] Existing technologies have several problems: 1. Traditional concealed doors mostly use a 90-120 degree opening structure, making it difficult to achieve full-angle opening; 2. Ordinary hinge structures cannot achieve arbitrary stopping function; 3. Concealed doors require high precision in fitting with the wall, which can easily lead to gaps; 4. Unstable torque control can cause the door to swing or not close properly. Existing solutions still have shortcomings: 1. Hydraulic hinges are used for stopping, but there is a risk of oil leakage; 2. Spring-type positioning devices have insufficient positioning accuracy; 3. Door hinges with limiters limit the opening angle.
[0007] Therefore, it is essential to provide a decorative hidden door that can open 180 degrees and stop at any point, which can resolve the contradiction between the existing hidden door's ability to open at all angles and its precise positioning. Utility Model Content
[0008] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a decorative hidden door that can be opened 180 degrees and stopped at any time. This decorative hidden door can solve the contradiction between the full-angle opening and precise positioning of existing hidden doors, realize stepless hovering and silent operation, and improve the door's concealment effect and structural stability.
[0009] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A decorative concealed door that can be opened 180 degrees and stopped at any time includes a concealed door steel frame and a decorative panel; The steel frame of the concealed door is connected to the decorative panel via double-hook dry-hanging fittings; The steel frame of the concealed door includes a square steel frame, a main rotating shaft, and two vertically distributed connecting square steels that are symmetrical about each other. The square steel frame is welded together from two vertically distributed first square steel bars and three horizontally distributed second square steel bars. The main shaft includes a vertically distributed third steel bar, with fourth steel bars welded to both the upper and lower ends of the third steel bar, and a first adjustable torque disc damping shaft welded to the other end of the fourth steel bar. The main rotating shaft is rotatably connected to one of the first square steel bars via a first connecting piece and a second adjustable torque disc damping rotating shaft, and the main rotating shaft is rotatably connected to the connecting square steel bars via a second connecting piece and a third adjustable torque disc damping rotating shaft. The upper end of the connecting square steel located at the top is fixedly connected to the floor slab above the floor, and the lower end of the connecting square steel located at the bottom is fixedly connected to the ground.
[0010] Furthermore, the three second square steel bars are arranged horizontally at equal intervals, with one first square steel bar vertically welded to the left end of the three second square steel bars, and another second square steel bar vertically welded to the right end of the three second square steel bars. The upper surface of the first square steel bar is flush with the upper surface of the uppermost second square steel bar, and the lower surface of the first square steel bar is flush with the lower surface of the lowermost second square steel bar.
[0011] Furthermore, the first connector includes two fifth square steels that are symmetrically fixed laterally to the left side of the third square steel. The second adjustable torque disc damping shaft is welded to the left side of the two fifth square steels that are close to each other. The other end of the second adjustable torque disc damping shaft is welded to a sixth square steel, which is welded to one of the vertically distributed first square steels.
[0012] Furthermore, the length of the fifth square steel is less than half the length of the second square steel.
[0013] Furthermore, the spacing between the two sixth square steel bars is half the length of the first square steel bar.
[0014] Furthermore, the second connector includes two transversely distributed seventh square steels. The end of the first adjustable torque disc damping shaft away from the fourth square steel is welded to the right side of the two seventh square steels that are close to each other. One end of the third adjustable torque disc damping shaft is welded to the left side of the two seventh square steels that are far from each other. The other end of the third adjustable torque disc damping shaft is welded to the end of the connecting square steel that is close to the seventh square steel.
[0015] Furthermore, the first square steel, the second square steel, the third square steel, the fourth square steel, the fifth square steel, the sixth square steel, the seventh square steel, and the connecting square steel are all hot-dip galvanized square steel, and their cross-sectional dimensions are all the same.
[0016] Furthermore, the double-hook dry-hanging component is made of stainless steel.
[0017] Compared with the prior art, the beneficial effects of this utility model are: The decorative concealed door of this utility model mainly uses square steel of different lengths and adjustable torque disc damping shafts for rotational connection. It uses few types of materials and is easy to obtain, so it can be made on the construction site. Through three pairs of adjustable torque disc damping shafts, the concealed door can be opened in three stages, thus achieving an opening angle of 180 degrees, filling the gap of the traditional concealed door's 120-180 degree opening. The damping and torque force of the adjustable torque disc damping shafts can make the concealed door stop at any time, which is highly flexible, meets engineering requirements, has high safety performance, and low cost.
