[0027] The embodiments of the present application will be described in detail below with reference to the drawings.

[0028] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other in the case of no conflict. The present application will be described in detail below with reference to the drawings and in combination with the embodiments.

[0029] As shown in Figure 1 , the hinge 101 includes a hinge shaft 1011, a hinge hole 1012, a hole shaft connecting part 1013 and a mounting hole 1014. The variable hole pitch fan fixing frame 1 includes four groups of structures of the same hinge 101, and the hinge 101 is connected by the hinge hole 1012 and the hinge shaft 1011 structure.

[0030] As shown in Figure 2 , the fan fixing frame 1 includes four mutually sleeved hinges 101, and is used for fixing the fan 2. The hinge 101 moves along the axial direction, so as to adjust the distance between the mounting holes 1014, and satisfies the installation of the skeletons of different hole pitch fans 2.

[0031] The hinge shaft 1011 and the hinge hole 1012 are fixedly connected through the hole shaft connecting part 1013, and the mounting hole 1014 is arranged in the hole shaft connecting part 1013.

[0032] The hinge shaft 1011 of one hinge 101 can be sleeved into the hinge hole 1012 of another hinge 101, and the sleeved depth can be adjusted in the axial direction of the hinge hole 1012. In order to facilitate the sleeving, the diameter of the hinge shaft 1011 is slightly smaller than the inner hole diameter of the hinge hole 1012.

[0033] As shown in Figure 3 , a threaded hole is arranged in the mounting hole 1014. The screw passes through the mounting hole on the fan 2 and the threaded hole of the mounting hole 1014 to fix the fan 2 to the external support.

[0034] The threaded depth of the threaded hole of the mounting hole can be 5.5 mm at most. The outer hole diameter of the hinge hole 1012 is greater than or equal to 5 mm. The threaded depth of the mounting hole can be 5 mm, and the diameter of the outer wall of the pin hole of the hinge can also be 5 mm at least, so as to satisfy the installation and fastening in a narrow space.

[0035] One end of the hinge shaft 1011 is provided with a chamfer, and one end of the hinge hole 1012 towards the hole shaft connecting part 1013 is provided with a groove. When the hinge shaft 1011 of one hinge 101 is completely sleeved into the hinge hole 1012 of another hinge 101, the chamfer is inserted into the groove.

[0036] As shown in Figure 4 , during assembly, the hinges 101 are combined two by two, the hinge shaft 1011 of one hinge 101 is sleeved into the hinge hole 1012 of another hinge 101, and the other side is assembled in the same way, and finally two groups of four hinges 101 are inserted together to form a frame structure, as shown in Figure 5As shown in the figure. Finally, when the fan fixing frame 1 is installed with the fan 2, as long as the mounting hole 1014 is aligned with the through hole on the skeleton of the fan 2, it can be fixed by screwing. When the fan 2 is square, the length of the hinge shaft 1011 extending from the hinge hole 1012 is equal.

[0037] The hinge 101 can be freely adjusted along the direction of the hinge shaft 1011, ensuring that it is suitable for the skeletons of fans 2 with different hole distances.

[0038] In the embodiment of the utility model, as Figure 6 As shown in the figure. Because the space between the fan 2 and the external support 3 is very narrow, the fan 2 cannot be fixed to the external support 3 by traditional screws and nuts, therefore, the fan fixing frame 1 of the utility model can fix the fan 2 to the external support 3.

[0039] The beneficial effects of the embodiment of the utility model are as follows:

[0040] The variable-hole-distance fan fixing frame of the embodiment of the utility model solves the problems of the currently commonly used split type standard fastening method, such as difficulty in operation in a narrow space, easy to fall off, etc. The variable-hole-distance fan fixing frame of the embodiment of the utility model is a structure with adjustable hole distance, which can be applied to fans of different sizes without other accessories, and the structure is simple. After four groups of the same hinges are assembled, they are installed as a whole frame on the fan mounting surface and used for fixing the fan. At the same time, the variable-hole-distance fan fixing frame of the embodiment of the utility model has the advantages of small size, simple structure, firm structure, wide application, and can be mass-produced and used.

[0041] The above is only a specific embodiment of the utility model, which cannot limit the scope of the utility model. Therefore, the replacement of equivalent components or equivalent changes and modifications made within the scope of the utility model patent protection should still belong to the scope covered by the patent. In addition, the technical features in the utility model can be freely combined with each other, and the technical features can be freely combined with each other.
