Description

Technical Field

[0001] The present invention relates to the technical field of revolving doors, and more particularly to a closed door structure. Background Art

[0002] Common single-opening doors or sliding doors will produce direct exchange of indoor and outdoor airflow during the opening process. In order to avoid direct exchange of indoor and outdoor airflow during the opening process, revolving doors are usually used.

[0003] However, the existing revolving door needs to rotate 360 ​​degrees, resulting in a large volume of the revolving door, and is usually used for the main door of buildings such as hotels.

[0004] Therefore, in order to avoid direct exchange of indoor and outdoor airflow during the opening process, designing a smaller door structure is an urgent problem to be solved. Summary of the invention

[0005] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a closed door structure, which adopts a combination of rotation and translation to achieve the position switching of the door panel. No direct airflow exchange is generated during the opening process, and compared with the existing revolving door, the volume can be reduced to nearly half, thereby facilitating the installation of the closed door structure.

[0006] To achieve the above object, the present invention provides the following technical solutions: A closed door structure comprises a wall panel, an arc foyer located on one side of the wall panel, a door panel pivot seat located at the center of the arc foyer, and a door panel assembly connected to the door panel pivot seat; The arc foyer includes an outer opening of the foyer and an inner opening of the foyer connected to the wall panel; The door panel assembly comprises three door panels, the door panels can rotate along the door panel pivot seats, and the door panel pivot seats are provided with translation channels for the door panels to pass through; The door panel includes a first position located at the inner opening of the hallway, a second position located at the outer opening of the hallway, and a third position located in the extending direction of the translation channel; the door panel can be switched between the first position and the third position through the translation channel.

[0007] Furthermore, the closed door structure includes a closed state; in the closed state, one door panel is located at a first position, one door panel is located at a second position, and the other door panel is located at a third position.

[0008] Furthermore, the closed door structure includes an inside-outside opening process; after the inside-outside opening process, the door panel originally located at the first position switches to the third position after rotation, the door panel originally located at the second position switches to the first position after rotation and translation, and the door panel originally located at the third position switches to the second position after translation and rotation.

[0009] Furthermore, the closed door structure includes an outside-inside opening process; after the outside-inside opening process, the door panel originally located at the second position switches to the third position after rotation and translation, the door panel originally located at the first position switches to the second position after translation and rotation, and the door panel originally located at the third position switches to the first position after rotation.

[0010] Furthermore, the first position, the second position and the third position are arranged in a T shape.

[0011] Further, the door panel located at the third position is parallel to the wall panel.

[0012] Furthermore, the closed door structure is used in houses, aircraft, submarines or high-speed railways.

[0013] In summary, the present invention has the following beneficial effects: The closed door structure of the present invention uses a combination of rotation and translation to achieve position switching of the door panel. No airflow exchange is directly generated during the opening process, and compared with the existing revolving door, the volume can be reduced to nearly half, thereby facilitating the installation of the closed door structure.
