Description

Technical Field

[0001] This invention relates to the field of revolving door technology, and more specifically, to a closed door structure. Background Technology

[0002] Common single-leaf doors or sliding doors cause a direct exchange of airflow between the inside and outside during opening. To avoid this direct exchange of airflow, revolving doors are usually used.

[0003] However, existing revolving doors require a 360° rotation, resulting in a large size, and are typically used for the main entrances of buildings such as hotels.

[0004] Therefore, in order to avoid direct exchange of airflow between indoors and outdoors during opening, designing a smaller door structure is an urgent problem to be solved. Summary of the Invention

[0005] To address the shortcomings of existing technologies, the present invention aims to provide a closed door structure that uses a combination of rotation and translation to switch the position of the door panel. No airflow exchange is directly generated during the opening process, and the volume can be reduced to nearly half compared to existing revolving doors, thus facilitating the installation of the closed door structure.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A closed door structure includes a wall panel, an arc-shaped entrance hall located on one side of the wall panel, a door panel pivot seat located at the center of the arc-shaped entrance hall, and a door panel assembly connected to the door panel pivot seat. The arc-shaped entrance hall includes an outer opening and an inner opening that communicates with the wall panels; The door panel assembly includes three door panels, which are rotatable along a door panel pivot seat, and the door panel pivot seat is provided with a translation channel for the door panels to pass through. The door panel includes a first position located inside the entrance hall, a second position located outside the entrance hall, and a third position located in the direction of the extension of the sliding channel; the door panel can be switched between the first position and the third position via the sliding channel.

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

[0008] Furthermore, the closed door structure includes an inward and outward opening process; after the inward and outward opening process, the door panel originally located in the first position is rotated and then switched to the third position, the door panel originally located in the second position is rotated and then switched to the first position, and the door panel originally located in the third position is switched to the second position after translation and rotation.

[0009] Furthermore, the closed door structure includes an outward and inward opening process; after the outward and inward opening process, the door panel originally located in the second position is switched to the third position after rotation and translation, the door panel originally located in the first position is switched to the second position after translation and rotation, and the door panel originally located in the third position is switched 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] Furthermore, the door panel in the third position is parallel to the wall panel.

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

[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 the position switching of the door panel. No airflow exchange is generated directly during the opening process. Moreover, compared with the existing revolving door, the volume can be reduced to nearly half, thus facilitating the installation of the closed door structure. Attached Figure Description

[0018] A closed door structure, reference Figures 1 to 3 It includes a wall panel 1, an arc-shaped entrance hall 2 located on one side of the wall panel 1, a door panel pivot seat 3 located at the center of the arc-shaped entrance hall 2, and a door panel assembly connected to the door panel pivot seat 3; wherein, the arc-shaped entrance hall 2 includes an outer entrance hall opening 22 and an inner entrance hall opening 21 communicating with the wall panel 1; in this embodiment, the door panel assembly includes three door panels, which can rotate along the door panel pivot seat 3, and the door panel pivot seat 3 is provided with a translation channel 31 for the door panels to pass through; the door panels include a first position 51 located in the inner entrance hall opening 21, a second position 52 located in the outer entrance hall opening 22, and a third position 53 located in the extension direction of the translation channel 31; the door panels can switch between the first position 51 and the third position 53 through the translation channel 31.

[0019] Reference Figures 1 to 3 Specifically, in this embodiment, the door panel assembly includes a first door panel 41, a second door panel 42, and a third door panel 43. The door panel assembly in this embodiment requires at least three door panels. In other optional embodiments, the number of door panels can be increased as needed, and there is no limitation here.

[0020] Reference Figures 1 to 3 In this embodiment, the closed door structure includes a closed state, and its opening process includes an inward opening process and an outward-inward opening process. Specifically, in the closed state, the first door panel 41 is located in the first position 51, the second door panel 42 is located in the second position 52, and the third door panel 43 is located in the third position. The first door panel 41 located in the first position 51 closes the inner opening 21 of the hall, and the second door panel 42 located in the second position 52 closes the outer opening 22 of the hall.

[0021] Reference Figure 1 and Figure 2 The opening process involves people passing through the inner opening 21 and the outer opening 22 of the hall in sequence. Specifically, the first door panel 41, located at the first position 51, rotates inward toward the arc-shaped hall 2, and the second door panel 42, located at the second position 52, rotates outward toward the arc-shaped hall 2, allowing people to enter the arc-shaped hall 2 through the inner opening 21. After entering the arc-shaped hall 2, the third door panel 43, located at the third position 53, moves through the translation channel 31 and back to the first position 51, thus opening the inner opening 21 of the hall. The door is closed; the first door panel 41 rotates to the second position 52, thereby closing the outer opening 22 of the hall; the second door panel 42 rotates to the third position 53; then, the first door panel 41 rotates to the outside of the arc hall 2, and the third door panel 43 rotates to the inside of the arc hall 2, so that people can walk out of the arc hall 2 through the outer opening 22; finally, the first door panel 41 rotates to the third position 53, the third door panel 43 rotates to the second position 52, and the second door panel 42 moves to the first position 51 after passing through the translation channel 31.

[0022] Reference Figure 1 and Figure 2 After the opening process, the first door panel 41, which was originally in the first position 51, is rotated and then switched to the third position 53. The second door panel 42, which was originally in the second position 52, is rotated and then switched to the first position 51. The third door panel 43, which was originally in the third position 53, is switched to the second position 52 after being translated and rotated. During the opening process, there is no direct airflow exchange between the inner and outer sides of the arc-shaped hall 2.

[0023] Reference Figure 1 and Figure 3 The opening process involves a person passing through the outer opening 22 and the inner opening 21 of the hallway sequentially. Specifically, the second door panel 42, located at the second position 52, rotates inward towards the inside of the arc-shaped hallway 2, allowing the person to enter the arc-shaped hallway 2 through the outer opening 22. After entering the arc-shaped hallway 2, the first door panel 41, located at the first position 51, moves through the translation channel 31 to the third position 53. The third door panel 43, located at the third position 53, rotates back to the second position 52, thus closing the outer opening 22. The second door panel 42 then rotates... The door panel 41 moves to the first position 51, thereby closing the inner opening 21 of the hallway. Then, the first door panel 41, located in the third position 53, continues to rotate, the third door panel 43, located in the second position 52, rotates inward to the arc-shaped hallway 2, and the second door panel 42, located in the first position 51, moves into the sliding passage 31, allowing people to exit the arc-shaped hallway 2 through the inner opening 21. Finally, the first door panel 41 rotates to the second position 52, the third door panel 43 rotates to the first position 51, and the second door panel 42 moves to the third position 53 after passing through the sliding passage 31.

[0024] Reference Figure 1 and Figure 3 After the opening process, the second door panel 42, which was originally in the second position 52, is switched to the third position 53 after rotation and translation. The first door panel 41, which was originally in the first position 51, is switched to the second position 52 after translation and rotation. The third door panel 43, which was originally in the third position 53, is switched to the first position 51 after rotation. During the opening process, there is no direct airflow exchange between the inner and outer sides of the arc-shaped hall 2.

[0025] Reference Figures 1 to 3 The closed door structure in this embodiment does not directly generate airflow exchange during the opening process, and its volume can be reduced to nearly half compared to existing revolving doors, thus facilitating the installation of the closed door structure; that is, the closed door structure in this embodiment can be used in houses, aircraft, submarines, or high-speed trains, etc.

[0026] Reference Figure 1Preferably, in this embodiment, the arc-shaped entrance hall 2 is a quarter-circular arc-shaped entrance hall, with the first position 51, the second position 52, and the third position 53 arranged in a T-shape. The door panel located at the third position 53 is parallel to the wall panel 1, which facilitates the arrangement and entry / exit. Of course, in other optional embodiments, the arc length of the arc-shaped entrance hall 2 can be adjusted as needed, and there is no limitation here.

[0027] Reference Figure 1 In this embodiment, the door panel can rotate around the door panel pivot seat 3 and move through the translation channel 31. In order to realize the rotation and movement of the door panel at the same time, various transmission structures or combinations of transmission structures in the prior art can be used, which will not be elaborated here.
