The limiting module 463 is arranged on the outer end face of the movable plate 45.

[0029] It should be noted that when the knob 462 is rotated, the knob 462 drives the threaded rod 461 to rotate. Under the action of the threaded thrust, the threaded rod 461 moves upward or downward while rotating. The threaded rod 461 drives the movable plate 45 to move upward or downward. The movable plate 45 is limited and guided by the limiting module 463, ensuring the stability of the movement of the movable plate 45 and preventing the movable plate 45 from rotating.

[0030] In an optional embodiment, the limiting module 463 comprises two limiting blocks 4631 and two limiting grooves 4632, the two limiting blocks 4631 are respectively arranged on the front and back surfaces of the movable plate 45, and the two limiting grooves 4632 are respectively arranged on the front and back sidewalls of the inner cavity of the fixed groove 44, and the two limiting blocks 4631 are respectively and slidably connected with the two limiting grooves 4632.

[0031] It should be noted that the two limiting blocks 4631 and the two limiting grooves 4632 can limit and guide the movable plate 45, ensure the stability of the movable plate 45, and also prevent the movable plate 45 from rotating, thereby further ensuring the stability of the positioning assembly 47 during movement and ensuring the positioning effect of the positioning assembly 47.

[0032] In an optional embodiment, the positioning assembly 47 comprises a positioning block 471 and a positioning groove 472, the positioning groove 472 is arranged on the top of the connecting block 43, and the positioning block 471 is arranged on the bottom of the movable plate 45 and slidably connected with the inside of the positioning groove 472.

[0033] It should be noted that when the movable plate 45 moves upward or downward, the movable plate 45 drives the positioning block 471 to move upward or downward, during the installation of the casement body 2, the knob 462 is rotated to drive the positioning block 471 to move downward, and when the positioning block 471 is slidably connected with the inside of the positioning groove 472, the connecting block 43 can be positioned by the positioning block 471 and the positioning groove 472 to prevent the connecting block 43 from deviating or falling off in the horizontal direction, and when the casement body 2 needs to be disassembled, the knob 462 is reversely rotated to drive the positioning block 471 to move upward, and when the positioning block 471 is separated from the positioning groove 472, the top of the connecting block 43 is lost, and the connecting block 43 can be taken out from the inside of the installation groove 42, and the casement body 2 can be further disassembled.

[0034] In an optional embodiment, the fixing assembly 48 comprises two fixing plates 481 and two fixing bolts 482, the two fixing plates 481 are respectively arranged on the front and back surfaces of the mounting block 41, and the two fixing bolts 482 are respectively arranged on the left sides of the two fixing plates 481 and extend into the inside of the window frame 1, and the two fixing bolts 482 are all threadedly connected with the window frame 1.

[0035] It should be noted that before the installation of the casement body 2, the mounting block 41 needs to be mounted into the inside of the window frame 1 according to the height of the casement body 2, and during the installation of the mounting block 41, the two fixing bolts 482 are directly rotated to be threadedly connected with the window frame 1, so that the mounting block 41 can be stably installed.

[0036] In an alternative embodiment, the mounting mechanism 4 has two sets, and the two sets of mounting mechanism 4 are symmetrically distributed at the top and bottom of the window air conditioner body 2.

[0037] It should be noted that the top and bottom of the window air conditioner body 2 can be fixed and supported by the two sets of mounting mechanism 4 respectively, so as to ensure the stability of the window air conditioner body 2 after installation, and further prevent the window air conditioner body 2 from being offset up and down after installation.
