The transmission bar 1 has an opening 11; the transmission component 2 has a protrusion 21 that engages with the opening 11; a vertical plate 12 is provided on one side of the transmission bar 1, and a hook 13 is provided on the side of the transmission bar 1 away from the vertical plate 12, with the opening of the hook 13 facing away from the vertical plate 12. By setting the transmission bar 1 and the transmission component 2, the reliability and stability of the transmission function are achieved. The vertical plate 12 on the transmission bar 1 increases the overall strength of the structure, enabling it to exhibit higher stability and durability when subjected to external forces and pressure. The hook 13 on the transmission bar 1 engages with the C-shaped groove on the window sash 3, making the installation and replacement process simpler, reducing installation costs, shortening installation time, and ensuring the opening and closing function and overall performance of the doors and windows.

[0035] As a preferred embodiment of this utility model, it may also have the following additional technical features: there are two transmission components 2, and openings 11 are respectively provided at both ends of the transmission bar 1. The protrusions 21 on the two transmission components 2 respectively cooperate with the openings 11 at both ends of the transmission bar 1 to form a stable support structure, which helps to prevent the transmission bar 1 from bending or deforming when subjected to force, thereby improving the stability of the overall structure.

[0036] As a preferred embodiment of this utility model, it may also have the following additional technical features: the opening 11 is a circular hole, and the protrusion 21 is a cylindrical block. The cylindrical block and the circular hole engage with each other, which can reduce friction and resistance during transmission, thereby improving transmission efficiency. The radius of the circular hole is greater than or equal to the radius of the cylindrical block, making the assembly and disassembly process simpler and faster. The user only needs to align the cylindrical block with the circular hole and gently push it in to complete the assembly. Similarly, disassembly only requires a little force to pull out the cylindrical block.

[0037] As a preferred embodiment of this utility model, it may also have the following additional technical features: the transmission component 2 includes a connecting base plate 22, a transmission plate 23, and a protruding post 24. The transmission plate 23 is fixedly connected to the connecting base plate 22, and the protruding post 24 is fixedly connected to the side of the transmission plate 23 away from the connecting base plate 22. The protruding post 24 is located at the end of the transmission plate 23 away from the protrusion 21, and the protrusion 21 is fixedly connected to the side of the transmission plate 23 away from the protruding post 24. The protrusion 21 cooperates with the opening 11 on the transmission bar 1 to ensure the accurate positioning of the transmission component 2 during transmission; while the protruding post 24 can provide additional support or positioning functions when needed.

[0038] As a preferred embodiment of this utility model, it may also have the following additional technical features: the width of the connecting base plate 22 is greater than the width of the transmission plate 23. The wide connecting base plate 22 can distribute the force and improve the load-bearing capacity of the transmission component 2.

[0039] As a preferred embodiment of this utility model, it may also have the following additional technical features: the length of the connecting base plate 22 is less than the length of the transmission plate 23. The transmission plate 23 requires a longer length to ensure effective power transmission, while the connecting base plate 22 only needs a sufficient length to connect to and support the transmission plate 23.

[0040] As a preferred embodiment of this utility model, it may also have the following additional technical features: the transmission plate 23 includes a first panel 231, a connecting transition plate 232, and a second panel 233, which are connected sequentially. A protrusion 21 is fixedly connected to the first panel 231, a protruding post 24 is fixedly connected to the second panel 233, and the second panel 233 is fixedly connected to the connecting base plate 22. In this embodiment, the first panel 231, the connecting transition plate 232, and the second panel 233 are stepped, with the first panel 231 higher than the second panel 233. The connecting transition plate 232 is located between the first panel 231 and the second panel 233, serving as a transition and connection, and has a specific shape and size to adapt to the spatial relationship between the first panel 231 and the second panel 233.

[0041] In a preferred embodiment of this utility model, it may also have the following additional technical features: the length of the second panel 233 is greater than or equal to the length of the first panel 231. In this embodiment, the length of the second panel 233 is greater than the length of the first panel 231, and the extra length of the second panel 233 is used to provide additional support or connection points to enhance the stability of the entire system.

[0042] As a preferred embodiment of this utility model, it may also have the following additional technical features: all transition angles of the transmission bar 1 are rounded, which effectively reduces the stress concentration phenomenon of the transmission bar 1 when under force and improves the strength and durability of the transmission bar 1.

[0043] Please see Figures 7-9 This embodiment also provides a door and window, including a window sash 3 and a hook-type transmission structure as described above. The window sash 3 is provided with a C-shaped groove, and the hook-type transmission structure is engaged with the C-shaped groove.

[0044] The working principle of the hook-type transmission structure in this embodiment is as follows: First, hook 13 into one end of the C-shaped groove 31, then rotate the transmission bar 1 so that the transmission bar 1 is fully inserted into the C-shaped groove 31. Then, align the protrusion 21 on the transmission component 2 with the opening 11 and engage it. Subsequently, insert the transmission component 2 into the C-shaped groove 31, at which point the connecting base plate 22 abuts against the C-shaped groove 31.
