[0087] refer to Figure 1 , Figure 2 , Figure 9 , Figure 16 and Figure 23 In some specific embodiments of this utility model, a first through hole 212 is provided at the center of the first cover plate 210, a second through hole 222 is provided at the center of the first base 220, a third through hole 232 is provided at the center of the rotating wheel 230, a fourth through hole 242 is provided at the center of the second base 240, and a fifth through hole 252 is provided at the center of the second cover plate 250. The external rotating part passes through the first through hole 212, the second through hole 222, the third through hole 232, the fourth through hole 242 and the fifth through hole 252 in sequence. The rotation of the external rotating part drives the rotating wheel 230 to rotate.

[0088] In some embodiments, the first through hole 212, the second through hole 222, the fourth through hole 242, and the fifth through hole 252 are circular holes, and the third through hole 232 is a square hole; alternatively, the first through hole 212, the second through hole 222, the third through hole 232, the fourth through hole 242, and the fifth through hole 252 are all square holes, and the outer rotating part is provided with a square shaft. The square shaft of the outer rotating part passes through the first through hole 212, the second through hole 222, the third through hole 232, the fourth through hole 242, and the fifth through hole 252 in sequence. When the outer rotating part is rotated, it can drive the rotating wheel 230 to rotate. In some embodiments, a transmission part, such as a transmission shaft or others, is also provided between the outer rotating part and the rotating wheel 230 to better transmit the force of the outer rotating part to the rotating wheel 230, or in other words, to better enable the outer rotating part to drive the rotating wheel 230 to rotate.

[0089] refer to Figure 1 , Figure 2 , Figure 9 , Figure 16 and Figure 23 In some specific embodiments of this utility model, a first receiving groove 223 is provided on the side of the first base 220 facing the rotating wheel 230, and a second receiving groove 243 is provided on the side of the second base 240 facing the rotating wheel 230. The rotating wheel 230 is housed in the receiving space between the first receiving groove 223 and the second receiving groove 243. The wheel teeth 231 of the rotating wheel 230 extend out of the receiving space and the housing and are inserted into the moving hole 121.

[0090] In this embodiment, the accommodating space formed between the first accommodating groove 223 and the second accommodating groove 243 can be used to accommodate the rotating wheel 230, thereby fixing the rotating wheel 230. Furthermore, the teeth 231 of the rotating wheel 230 can extend out of the accommodating space and the housing and be inserted into the moving hole 121 of the moving piece 120 without affecting the cooperation between the rotating wheel 230 and the moving piece 120.

[0091] This utility model also provides a door or window, including the transmission mechanism described in any of the preceding embodiments.

[0092] For different types of doors and windows, such as hinged doors or windows and sliding doors or windows, the transmission mechanism can effectively transmit the external force generated by manual or electric operation, driving the door or window sash to move along a predetermined track or hinge structure, thereby smoothly realizing the opening operation and allowing the door or window to open; when it is necessary to close the door or window, the transmission mechanism is also relied on to make the door or window sash return to the closed position accurately and ensure that it is closed tightly.

[0093] For example, a rotating part (sometimes referred to as an external rotating part) connects to a rotating wheel 230. Manual rotation of the rotating part causes the rotating wheel 230 to rotate, which in turn moves the movable piece 120, thus opening and closing the door or window. The rotating part can be a handle for a person to grip and turn. Alternatively, through automated design, the rotating wheel 230 can rotate automatically, driving the movable piece 120 to open and close the door or window. Thus, through manual or automated intelligent operation, the transmission mechanism can convert the rotational motion of the rotating wheel 230 into the linear motion of the movable piece 120, thereby opening and closing the door or window.

[0094] The door or window provided by this utility model includes a transmission mechanism with a replaceable design. The transmission component 100 is shared, requiring only the stocking of drive components 200 with different center distances. By replacing the drive component 200, different center distances can be met, enabling convenient and free switching of center distances and reducing the difficulty of stocking and warehousing for manufacturers. In addition, the transmission component 100 only needs to be connected to the drive component 200 through a connector, allowing for quick assembly and disassembly. Furthermore, all structures are securely fixed to each other, resulting in high structural strength and load-bearing capacity.
