[0032] When the equipment in the cabinet is running, the air guide plate 6 is rotated outward to open until the side wall of the air guide plate 6 fits against the limiting structure protruding laterally at the lower end of the fixing member 1 to prevent the air guide plate 6 from flipping over excessively; when the cabinet needs operation and maintenance, before opening the cabinet door or the air outlet window, the air guide plate 6 is rotated inward until the second positioning structure of the air guide plate 6 is engaged and fixed with the first positioning structure of the fixing member 1, and after the air guide plate 6 is in a closed state, the cabinet door or the air outlet window is opened to avoid collision and reduce the disassembly work of the operation and maintenance personnel.

[0033] Optionally, the first positioning structure and the second positioning structure are snap-fitted, and the first positioning structure adopts a protrusion protruding from the surface of the fixing member 1 or a groove recessed into the surface of the fixing member 1, and the corresponding second positioning structure adopts a groove or protrusion adapted thereto. That is, when the first positioning structure adopts a protrusion protruding from the side wall of the fixing member 1, the corresponding second positioning structure adopts a groove; conversely, when the first positioning structure adopts a groove, the corresponding second positioning structure adopts a protrusion protruding from the side plate of the air guide plate 6. In addition, the first positioning structure and the second positioning structure can also be connected in a limited position by means of elastic bayonet pins, bolts, etc.

[0034] The limiting structure can be a bolt or a plate protruding from the side wall of the fixing member 1. When the air guide plate 6 is opened, it rotates outward until its outer wall is attached to the limiting structure, and the air guide plate 6 cannot be turned over further, and the opening angle of the air guide plate 6 is fixed.

[0035] In some possible embodiments, see Figure 1 The fixing member 1 includes a first straight plate portion and a second straight plate portion that are vertically connected.

[0038] Specifically, there are two fixing members 1, and the two fixing members 1 are symmetrically arranged on both sides of the air outlet; the limiting structure is located on the side of the fixing member 1 facing the air outlet. That is, in order to improve the stability of the air guide plate, fixing members 1 are installed on both sides of the air outlet, and the structures of the two fixing members 1 are consistent and symmetrically arranged. The two sides of the air guide plate 6 are respectively connected to the corresponding fixing members 1, and the structures of the side panels of the air guide plate 6 facing the two fixing members 1 are consistent, and both are provided with a second positioning structure. The air guide plate 6 is located between the two fixing members 1, and the limiting structure is used to limit the air guide plate 6, which needs to extend horizontally toward the direction of the air outlet to protrude from the outer wall of the fixing member 1 and extend to the bottom of the air guide plate 6.

[0039] In some possible embodiments, see Figure 1 The limiting structure is a bending structure arranged at the lower end of the fixing member 1 , and the upper end surface of the bending structure is in contact with the air guide plate 6 in the open state to limit the flipping angle of the air guide plate 6 .

The bending structure extends transversely to the bottom of the air guide plate 6. The upper end surface of the bending structure is a horizontal surface or an inclined surface, which is used to fit the air guide plate 6 to limit the rotation angle of the air guide plate 6.

[0041] In some possible embodiments, see Figure 1 The fixing member 1 is also provided with a hinge hole 5, which is a longitudinally arranged long hole, and the hinge shaft 8 is movably connected to the long hole. Specifically, the lower end of the second straight portion 3 is provided with a hinge hole 5, and the hinge shaft 8 connected to the lower end of the air guide plate 6 passes through the hinge hole 5 and rotates with the hinge hole 5. The second straight portion 3 is provided with a first positioning structure, a hinge hole 5 and a limit structure at intervals along its length direction.

At this time, the air guide plate 6 is moved downward, and the hinge shaft 8 moves downward along the bar-shaped hinge hole 5, and the positioning bolt 7 enters the bottom of the sink. The positioning bolt 7 is limited in the sink to prevent the air guide plate 6 from rotating.

[0046] Optionally, the positioning notch 4 and the sink groove both horizontally penetrate the side walls of both ends of the fixing member 1. The positioning bolt 7 includes a screw rod and a nut, wherein the diameter of the nut is larger than the width of the positioning notch 4 and the width of the sink groove.
