DETAILED DESCRIPTION

[0020] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0021] Example

[0022] Please refer to Figure 1-Figure 5 A circular window that rotates to open and close comprises an annular window frame 1, which is arranged on a building. A window sash portion 2 is rotatably connected to the inner side of the annular window frame 1. The window sash portion 2 comprises an annular window sash frame 20. An annular groove 210 is provided along the outer circumference of the annular window sash frame 20. Two arcuate sealing blocks 22 are inserted in the annular groove 210. The two arcuate sealing blocks 22 are arranged on the annular window sash frame 20 facing each other. Two arcuate sealing grooves 5 corresponding to the arcuate sealing blocks 22 are provided on the inner side of the window sash portion 2. When the annular window sash frame 20 is rotated to be parallel to the annular window frame 1, each arcuate sealing block 22 coaxially corresponds to an arcuate sealing groove 5. When the arcuate sealing block 22 coaxially moves into the arcuate sealing groove 5, the interior of the arcuate sealing groove 5 is filled by the arcuate sealing block 22.

[0023] In order to facilitate the movement of the two arc-shaped sealing blocks 22 closer to or away from the arc-shaped sealing groove 5, in an optional embodiment: the present application also includes a maneuvering assembly, the maneuvering assembly includes a fixed shell 3, a threaded rod 31, a driving motor 34 and two nut blocks 32, the fixed shell 3 is installed on the inner wall of the window sash portion 2, the driving motor 34 is installed on one side of the inner wall of the fixed shell 3, one end of the threaded rod 31 is connected to the output shaft of the driving motor 34, the other end of the threaded rod 31 is rotatably connected to the other side of the inner wall of the fixed shell 3, the two nut blocks 32 are symmetrically connected to the threaded rod 31, the nut blocks 32 and the threaded rod 31 are threadedly connected, and the two nut blocks 32 have a moving rod 33 on the opposite side, and one end of the moving rod 33 moves through the fixed shell 3 and the annular window sash frame 20 in turn and is connected to one side of the arc-shaped sealing block 22.

[0024] Specifically, a guide rod parallel to the threaded rod 31 is fixedly connected inside the fixed shell 3. One end of the two nut blocks 32 are slidably sleeved on the surface of the guide rod. The two nut blocks 32 are limited by the guide rod so that the nut blocks 32 can move stably. Two groups of threads with opposite directions are provided on the threaded rod 31. When the threaded rod 31 is rotated, the two nut blocks 32 can move toward or away from each other, thereby driving the two arc-shaped sealing blocks 22 to move toward or away from each other.

[0025] In an optional embodiment: the window sash portion 2 also includes an annular connecting frame 21, which is installed on one side of the annular window sash frame 20. The top and bottom sides of the annular connecting frame 21 both have a rotating shaft 211, and the rotating shaft 211 is rotatably connected to the annular window frame 1. Glass is installed on the inner side of the annular window sash frame 20. Specifically, glass is filled on the inner side of the annular window sash frame 20 to isolate the indoor and outdoor areas.

[0026] In an optional embodiment: a limit plate 4 is provided on the inner wall of the annular window frame 1 on the side close to the indoor room. When the annular window sash frame 20 is rotated to be parallel to the annular window frame 1, the annular window sash frame 20 is closer to the indoor room than the annular connecting frame 21. The limit plate 4 contacts the annular window sash frame 20, so that the angle limiting effect of the entire window sash portion 2 can be activated by the limit plate 4, which facilitates the judgment that the window sash portion 2 is parallel to the annular window frame 1.

[0027] In an optional embodiment, the arc-shaped sealing block 22 includes a reinforcing rib layer 222 , and sealing material layers 221 are fixedly connected to both sides of the reinforcing rib layer 222 , so that the reinforcing rib layer 222 can activate the reinforcing effect on the structure of the entire sealing block.

[0028] When closing, the two arc-shaped sealing blocks 22 can be stably maintained in the position state in the arc-shaped sealing groove 5 by adjusting the assembly, so that the entire window sash portion 2 is stably fixed to the annular window frame 1. When not closing, it is only necessary to control the driving motor 34 to drive the threaded rod 31 to rotate, move the two arc-shaped sealing blocks 22 toward each other to disengage from the arc-shaped sealing groove 5, and then rotate the window sash portion 2. Therefore, when closing, the window sash portion 2 and the annular window frame 1 are effectively sealed, and the window sash portion 2 can be stably fixed to the annular window frame 1, which saves time and effort and improves the performance.

[0029] In an optional embodiment: a control switch is installed on the fixed shell 3, and the drive motor 34 is electrically connected to the control switch. The drive motor 34 is conveniently controlled by the control switch. The number of turns of the drive motor 34 in the forward or reverse direction can be preset through the control switch, thereby controlling the moving distance of the two nut blocks 32.

[0030] In an optional embodiment, the outer side surface of the window sash portion 2 contacts the inner side surface of the annular window frame 1, so that the window sash portion 2 itself can also play a certain filling and sealing role in the gap at the connection between the annular window frame 1 and the window sash portion 2 when the round window is closed.

[0031] Specifically, when closing the window sash, first rotate the window sash portion 2 to contact and limit the position with the limit plate 4, so that the window sash portion 2 is set parallel to the annular window frame 1, and the annular window sash frame 20 is in a closed state on the annular window frame 1. The driving motor 34 is driven to rotate by the control switch, and the moving rod 33 drives the two nut blocks 32 to move apart, and then drives the two arc-shaped sealing blocks 22 to move apart, so that each arc-shaped sealing block 22 is coaxially inserted into an arc-shaped sealing groove 5, respectively, so that the arc-shaped sealing block 22 can fill and seal the arc-shaped sealing groove 5, and most of the outdoor air is isolated from flowing into the room through the gap at the connection between the annular window sash frame 20 and the annular window frame 1 through the arc-shaped sealing block 22.

[0032] Furthermore, when closing, the position of the two arc-shaped sealing blocks 22 in the arc-shaped sealing groove 5 can be stably maintained by adjusting the assembly, so that the entire window sash portion 2 is stably fixed to the annular window frame 1. When not closing, it is only necessary to control the drive motor 34 to drive the threaded rod 31 to rotate, so that the two arc-shaped sealing blocks 22 move toward each other to disengage from the arc-shaped sealing groove 5, and then rotate the window sash portion 2. Therefore, when closing, the window sash portion 2 and the annular window frame 1 are effectively sealed, and the window sash portion 2 can be stably fixed to the annular window frame 1, which saves time and effort and improves the performance.

[0033] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
