The cover body 1 is provided with a plurality of front positioning holes, and the back cover plate is provided with a plurality of rear positioning holes 2 corresponding to the front positioning holes, and when being installed, positioning screws 3 are fixed into the cover body 1 after penetrating through the rear positioning holes 2 and the front positioning holes, so as to install and fix the back cover plate on the cover body 1, and the rear positioning holes 2 are arranged close to the corner positions of the splicing plates 4 to facilitate the installation of the positioning screws 3 on the rear positioning holes 2. The back cover plate comprises a plurality of splicing plates 4, each of which is provided with a sliding block 401 and a sliding groove 402, the sliding block 401 is used for slidingly being installed on the sliding groove 402 of the adjacent splicing plate 4, and the adjacent two splicing plates 4 are connected through the sliding block 401 and the sliding groove 402. As a preferred embodiment, the setting mode of the sliding block 401 and the sliding groove 402 on the splicing plate 4 can be as follows: assuming that the splicing plate 4 is quadrangular and has four edges, namely a first edge, a second edge, a third edge and a fourth edge, the first edge is parallel to the third edge, and the second edge is parallel to the fourth edge, the first edge and the second edge are both provided with the sliding block 401, and the third edge and the fourth edge are both provided with the sliding groove 402. If the back cover plate is formed by two splicing plates 4 being spliced with each other at this time, the two splicing plates 4 are a first splicing plate and a second splicing plate, the sliding block 401 on the first edge or the second edge of the first splicing plate 4 is slidingly installed with the sliding groove 402 on the third edge or the fourth edge of the second splicing plate 4, and the position of the sliding groove 402 on the second splicing plate 4 is close to the position of the sliding block 401 on the first splicing plate 4, so as to realize the installation between the first splicing plate 4 and the second splicing plate 4. That is, the adjacent two splicing plates 4 are installed in a slidingly installed mode, and through such an installation mode, the back cover plate can flexibly cope with the installation of various sizes of fan main bodies 9, and in different sizes of cover bodies 1, a proper number of splicing plates 4 are spliced to form the back cover plate, so as to adapt to the installation of various sizes of cover bodies 1.

[0025] Further, the plurality of splicing plates 4 can be arranged in a rectangular array, and the adjacent two splicing plates 4 are connected through the sliding block 401 and the sliding groove 402, Figure 1As shown in the assumption that the splicing plate 4 has four pieces and is in a rectangular array at this time, the connection mode between the splicing plates 4 is that the sliding block 401 is slidably installed to the sliding groove 402 to realize the connection between adjacent splicing plates 4. Moreover, in order to make the installation stability between the connected splicing plates 4 high, the limiting hole 6 is arranged on each adjacent corner of the adjacent four splicing plates 4 in a rectangular array, and the limiting rubber nail 5 is installed through the limiting hole 6. Specifically, the limiting rubber nail 5 includes a base plate 501 and four limiting columns 502 arranged on the base plate 501, the limiting columns 502 are matched and installed with the limiting hole 6, and the four limiting columns 502 are inserted into the splicing plate 4 after passing through the limiting hole 6, so as to limit the position of the four splicing plates 4 through the limiting rubber nail 5. In this way, when the sliding installation between the splicing plates 4 is completed, the limiting rubber nail 5 will be installed between every four splicing plates 4 in a rectangular array, so as to well limit the position of each splicing plate 4 and improve the working stability.

[0026] Next, referring to Figure 4 , in order to improve the installation stability of the limiting rubber nail 5 in the limiting hole 6 of the splicing plate 4, the limiting ring 7 is arranged on the limiting column 502 of the limiting rubber nail 5, and the diameter of the limiting ring 7 is larger than the diameter of the limiting hole 6. The structure of arranging the limiting ring 7 on the limiting column 502, when the limiting column 502 is inserted into the limiting hole 6, since the material of the whole limiting rubber nail 5 is plastic material, the overall structure is very soft, and after the limiting column 502 with the limiting ring 7 is inserted into the limiting hole 6, the limiting ring 7 will enter the cover body 1, since the size of the limiting ring 7 is larger than the diameter of the limiting hole 6, the limiting ring 7 will be limited in the cover body 1, so as to realize the installation of the limiting rubber nail 5 between the plurality of splicing plates 4.

[0027] In addition, a plurality of ventilation holes 8 are arranged on the splicing plate 4, wherein the diameter of the ventilation hole 8 is not greater than 4mm, so as to avoid that the size of the ventilation hole is too large and reduce the occurrence of production accidents. Moreover, as a preferred embodiment, the plurality of ventilation holes 8 are arranged in a grid shape.

[0028] Further, in order to facilitate the installation between the splicing plates 4, the sliding block 401 and the sliding groove 402 are in a strip shape, the length of the sliding block 401 is smaller than the length of the sliding groove 402, and the sliding of the strip-shaped sliding block 401 in the strip-shaped sliding groove 402 is more convenient, so as to reduce the installation time between the splicing plates 4 and improve the assembly efficiency.
