Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

The driven wheel 7 is fixedly connected, and the protective shell 6 is fixedly connected to the upper surface of the movable frame 5. The guide plate 14 is fixedly connected to the inner side of the protective shell 6. One side of the movable plate 15 is slidably connected to the guide plate 14 through the opened guide groove. The other side of the movable plate 15 is fixedly connected to the rack 16, which meshes with the driven wheel 7. The auxiliary servo cylinder 12 is fixedly connected to the inner side of the protective shell 6. The telescopic rod of the auxiliary servo cylinder 12 is fixedly connected to the movable plate 15 through the push block 13. The two ends of the main servo cylinder 11 are movably connected to the lower surfaces of the fixed frame 2 and the movable frame 5 through the movable seats.
[0019] In this embodiment, the fixed frame 2 is fixedly connected to the air outlet of the fan coil unit body 1 by bolts, so that the air outlet angle adjustment assembly composed of the fixed frame 2 and the movable frame 5 can be fully assembled with the fan coil unit body 1. During the use of the fan coil unit, when it is necessary to adjust the air outlet angle at the air outlet of the fan coil unit body 1, if the switch of the main servo cylinder 11 is activated, the extension rod of the main servo cylinder 11 can push the movable frame 5 to rotate around the fixed column 9, and then the movable frame 5 can adjust the air outlet angle in the vertical plane. If the auxiliary servo cylinder 11 is activated, the extension rod of the main servo cylinder 11 can push the movable frame 5 to rotate around the fixed column 9, and then the movable frame 5 can adjust the air outlet angle in the vertical plane. The switch of cylinder 12 allows the extension rod of the auxiliary servo electric cylinder 12 to push the moving plate 15 to move via the push block 13. The moving plate 15 can drive multiple sets of driven wheels 7 through the rack 16. The driven wheels 7 can synchronously drive the corresponding adjusting plate 8 to rotate, thereby allowing the adjusting plate 8 to rotate within the cavity of the movable frame 5. In turn, the cavity of the movable frame 5 can adjust the air outlet angle in the horizontal plane through the adjusting plate 8, thereby improving the convenience and flexibility of adjusting the air outlet angle of the fan coil unit, enhancing its practicality during use, and ensuring the uniformity of the ambient temperature.

All four sets of fixing grooves 3 have an L-shaped structure. At the same time, through holes are symmetrically opened on the side of the fixing groove 3 near the fan coil body 1, and bolts are screwed through the through holes to the fan coil body 1.
[0021] In this embodiment, as Figure 1 and Figure 3 The opening of the fixing groove 3 allows the fixing frame 2 to be fixedly connected to the fan coil body 1 by bolts, thereby enabling the air outlet angle adjustment component to be installed at the air outlet of the fan coil body 1, realizing the adjustment of the air outlet angle and enhancing the practicality of the fan coil.
[0022] In a preferred embodiment, the two sets of fixing plates 10 fixedly connected to the outer side of the fixed frame 2 are both rectangular in structure, and the fixing column 9 movably connected to the fixing plate 10 is cylindrical in structure, while the surface of the fixing plate 10 is in contact with the outer side of the movable frame 5.
[0023] In this embodiment, as Figure 1 , Figure 2 and Figure 3 The setting of the fixed plate 10 and the fixed column 9 allows the movable frame 5 to be movably connected to the fixed frame 2. Then, by rotating the movable frame 5, the air outlet angle in the vertical plane can be adjusted, which can also help enhance the stability of the movable frame 5 when rotating.
[0024] In a preferred embodiment, multiple sets of adjustment plates 8 are movably connected in parallel and at equal intervals along the horizontal direction inside the movable frame 5. The multiple sets of adjustment plates 8 are all rectangular in structure, and the horizontal cross section of the adjustment plate 8 is spindle-shaped. At the same time, the two ends of the adjustment plate 8 are respectively attached to the top and bottom of the inner cavity of the movable frame 5.
[0025] In this embodiment, as Figure 1 , Figure 2 and Figure 3 The structure of the regulating plate 8 can effectively reduce the obstruction effect of the regulating plate 8 on the airflow, and the size of the regulating plate 8 allows the airflow direction to be adjusted when the airflow passes through the movable frame 5, thereby realizing the adjustment of the air outlet angle in the horizontal plane.
[0026] In a preferred embodiment, the protective shell 6 has a cuboid structure, the cross-section of the protective shell 6 has a U-shaped structure, and the guide plate 14 fixedly connected to the inner side of the protective shell 6 has a long strip structure, while the end face of the guide plate 14 has a dovetail structure. At the same time, the driven wheel 7 and the rack 16 are both located inside the protective shell 6.
[0027] In this embodiment, as Figure 2 , Figure 3 and Figure 4 The protective shell 6 allows the driven wheel 7 and rack 16 to mesh and transmit power in a relatively enclosed environment, thereby reducing the probability of unexpected failures in the meshing transmission due to foreign objects.
[0028] In a preferred embodiment, the movable plate 15 has a long strip structure, and the cross-section formed by the movable plate 15 and the guide groove is U-shaped. The guide groove and the guide plate 14 are matched in size, and the push block 13 fixedly connected to the upper surface of the movable plate 15 has a square structure.
