[0001] The utility model belongs to the technical field of doors, and in particular relates to a heavy-duty rotating shaft invisible door system. Background Art

[0002] Doors play the role of protection and separation in buildings, and facilitate traffic in and out. Invisible doors, as the name suggests, make the door and the wall blend into one, making it difficult to distinguish, making the door invisible and look magical. However, the existing invisible door structure is relatively cumbersome to install and has a small load.

[0003] The current invisible door structure is relatively simple, and its surface is a single plane structure. This structure makes the coordination between the invisible door and the wall not concealed enough, and the invisible door is usually thick and heavy, which is not only troublesome to install but also affects the appearance. In addition, the invisible door will become loose after long-term use and will not be stable when opening and closing. Due to the lack of toughness and elastic limit when opening and closing the invisible door, it is easy to collide when closing, and thus easy to be damaged. Utility Model Content

[0004] The purpose of the utility model is to provide a heavy-duty rotating shaft invisible door system, which aims to solve the problems in the prior art that the invisible door will become loose after long-term use, is not stable when opening and closing, and lacks toughness and elastic limit when opening and closing the invisible door, which makes it easy to collide when closing and thus easy to be damaged.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] Heavy-duty pivot invisible door system, including:

[0007] A door frame, wherein a door leaf is arranged in the door frame, wherein the upper and lower cross bars of the door frame are respectively fixedly connected to a lower shaft assembly and an upper shaft assembly, wherein the adjusting rotating ends of the two lower shaft assemblies are respectively fixedly connected to the upper and lower cross bars of the door leaf, and the front ends of the door frame and the door leaf are provided with an additional finishing layer;

[0008] The rebound, suction / positioner is arranged on the rear rigid structure of the door frame, the elastic end of the rebound, suction / positioner is close to the rear end of the door leaf, the installation position of the telescopic limiter corresponds to the rebound, suction / positioner, and the other end of the telescopic limiter is fixedly connected to the rebound, suction / positioner of the rear rigid structure.

[0009] Compared with the prior art, the beneficial effects of the present invention are:

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] Example 1

[0019] See also Figure 1-Figure 3, the utility model provides the following technical solutions:

[0020] The heavy-duty rotating invisible door system is characterized by comprising:

[0021] The door frame 3 has a door leaf 5 disposed therein. The upper and lower cross bars of the door frame 3 are fixedly connected to the lower shaft assembly 6 and the upper shaft assembly 1, respectively. The adjustable rotating ends of the two lower shaft assemblies 6 are fixedly connected to the upper and lower cross bars of the door leaf 5, respectively. The front ends of the door frame 3 and the door leaf 5 have an additional finishing layer 2.

[0022] The rebound, suction / positioner 7 is arranged on the rear rigid structure of the door frame 3. The elastic end of the rebound, suction / positioner 7 is close to the rear end of the door leaf 5. The installation position of the telescopic limiter 4 corresponds to the rebound, suction / positioner 7. The other end of the telescopic limiter 4 is fixedly connected to the rebound, suction / positioner of the rear rigid structure.

[0023] In this embodiment of the present invention, the door frame 3 provides the external support structure for the entire invisible door system, defining the door's overall outline and installation position. It secures and accommodates components such as the door leaf 5, lower shaft assembly 6, upper shaft assembly 1, and finishing layer 2, ensuring the stability and integrity of the entire system. Furthermore, the door frame 3 blends seamlessly with the surrounding walls or interior design, allowing the invisible door to blend seamlessly into the space when closed.

[0024] Second, the door leaf 5, as part of the main structural framework of the invisible door, primarily supports key door components, including the door's finishing layer. It connects to the door frame 3 via the lower shaft assembly 6 and the upper shaft assembly 1, enabling the door's rotational opening and closing. The strength and stability of the door leaf 5 directly impact the performance and lifespan of the invisible door.

[0025] Third, the upper and lower shaft assemblies 1 and 6 work together to provide the rotation axis for the door leaf 5. The adjustable rotating ends of the upper and lower shaft assemblies 1 and 6 are fixedly connected to the upper and lower crossbars of the door leaf 5, allowing the door leaf 5 to rotate around these two axes within the door frame 3, thereby opening and closing the door. This ensures accurate installation and ease of use.

[0026] Fourth, the finishing layer 2 is fixedly connected to the front end of the door frame 3 and the door leaf 5. On the one hand, it can increase the aesthetics of the invisible door and make the surface of the door more flat and uniform; the steel pipe thickness of the door frame 3 and the door leaf 4 is usually 4mm.

[0027] Fifth, the rebound, suction, and positioner 7 is located at the rear side of the door frame 3, with its elastic end in close contact with the rear end of the door leaf 5. When the door is opened, the rebound, suction, and positioner 7 generates a certain elastic force, causing the door to automatically open to a certain angle, facilitating its opening. When the door is closed, the rebound, suction, and positioner 7 generates a certain suction force, causing the door to automatically close, ensuring its sealing and stability. Simultaneously, the rebound, suction, and positioner 7 also serves as a positioning mechanism, ensuring that the door remains accurately in the predetermined position when closed, preventing it from loosening or shifting. The elastic end of the rebound, suction, and positioner 7 is magnetically connected to the door leaf 5, enabling the telescopic end of the rebound, suction, and positioner 7 to achieve adsorption.

[0028] 6. The telescopic stopper 4 is mounted in the same position as the rebound, pull-in / positioner 7. Its other end is fixedly connected to the rear rigid structure of the rebound, pull-in / positioner. The telescopic stopper 4 limits the door's opening and closing range, preventing it from opening or closing excessively. When the door is opened to a certain angle, the telescopic stopper 4 activates, preventing further opening and preventing damage to the door and surrounding structures. It also acts as a buffer when the door closes, reducing the impact and extending its service life.

[0029] The working principle and usage process of this utility model are as follows: The door frame 3 is fixed to a rigid structure and positioned so that it blends in with the surrounding wall or decoration. This provides external support for the entire invisible door system and determines the overall outline and installation position of the door. The door leaf 5 is placed within the door frame 3 and connected via the lower shaft assembly 6 and the upper shaft assembly 1. The adjustable rotating ends of the lower shaft assembly 6 and the upper shaft assembly 1 are respectively fixed to the upper and lower crossbars of the door leaf 5, allowing the door leaf 5 to rotate about these two axes to realize the door opening and closing function.

[0030] When installing the door leaf 5, the finishing layer 2 is fixedly connected to the door frame 3 and the front end of the door leaf 5. The finishing layer 2 enhances the invisible door's aesthetics and harmonizes the door surface with the surrounding finishing layers. The rebound, suction, and positioner 7 is positioned behind the door frame 3, with its elastic end in close contact with the rear end of the door leaf 5. The rebound, suction, and positioner 7 generates a spring force when the door is closed, assisting in opening and closing the door, ensuring stability, and also serving as a positioning mechanism.

[0031] The telescopic stopper 4 is mounted on the door leaf 5, corresponding to the position of the rebound and pull / positioner 7. It limits the door's opening and closing range, preventing excessive opening or closing. When the door reaches a certain angle, it stops further opening to prevent damage. It also acts as a buffer when closing, reducing impact and extending the door's service life.

[0032] Through the above operation process, the problems of existing invisible doors becoming loose after long-term use, being unstable when opening and closing, and lacking toughness and elastic limit causing easy collision and damage when closing are solved.

[0033] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
