[0027] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0028] like Figures 1-4 As shown, a fan structure in one embodiment of the present invention includes a housing 1, a motor 3 mounted on the housing 1, and a plurality of fan blades 2 fixedly connected to the output shaft of the motor 3.

[0029] In this embodiment, the housing 1 is a rectangular body, and the four corners of the housing 1 are chamfered. A connecting block 9 is installed at each of the four corners of the housing 1. A second threaded hole 901 is provided on the connecting block 9, and a second bolt 11 matching the second threaded hole 901 is threaded onto the connecting block 9. After the second bolt 11 passes through the second threaded hole 901, it is connected to the device to fix the cooling fan to the device.

[0030] like Figures 1-6 As shown, the connecting block 9 has a third threaded hole 902 that matches the second threaded hole 901. The outer diameter of the third threaded hole 902 is larger than the outer diameter of the second threaded hole 901. A locking block 12 that matches the third threaded hole 902 is installed on the connecting block 9. The outer wall of the locking block 12 has an external thread 1201, and a spring 13 that matches the second bolt 11 is fixedly connected to the external thread 1201. When the third threaded hole 902 is threaded into the locking block 12, one end of the spring 13 contacts the second bolt 11. Tightening the locking block 12 applies pressure to the second bolt 11, increasing the friction between the second bolt 11 and the second threaded hole 901, reducing the possibility of the second bolt 11 loosening due to vibration. Similarly, the elastic force generated by the spring 13 also strengthens the friction between the locking block 12 and the connecting block 9, further securing the locking block 12.

[0031] like Figures 1-4 As shown, the housing 1 has four end faces: top, bottom, left, and right. Connecting ropes 8 are installed between adjacent end faces. The connecting ropes 8 and connecting blocks 9 are mated. The connecting ropes 8 are elastic ropes. A second through hole 903 is provided on the connecting block 9, through which the connecting block 9 is slidably connected to the connecting rope 8. Thus, by sliding the connecting block 9 on the connecting rope 8 or pulling the connecting block 9 outwards, the elasticity of the connecting rope 8 allows the mounting holes on the device to match the second threaded hole 901 on the connecting block 9, and a threaded connection is achieved through a second bolt 11. Compared to traditional cooling fans, this design can adapt to devices with different mounting hole positions.

[0032] Among them, such as Figures 1-4 As shown, a second limiting protrusion 10 is fixedly connected to the connecting block 9, and a second limiting hole (not shown) matching the slide groove 101 is opened on the housing 1. When the second limiting protrusion 10 is located in the second limiting hole, the connecting block 9 is fixed, and the connecting block 9 is relatively stably fixed on the housing 1 by the tension of the connecting rope 8.

[0033] To allow housing 1 to accommodate more types of openings and to allow for adjustment of housing 1's position to ensure good fan cooling performance, such as... Figures 1-4As shown, two sliding grooves 101 are respectively opened on the four end faces of the housing 1, and sliders 4 that match the sliding grooves 101 are slidably connected to the housing 1. A first through hole 401 is opened on the slider 4, and the two ends of the connecting rope 8 are respectively fixed to the first through hole 401 on the slider 4. The two sliders 4 that fix the connecting rope 8 are adjacent, and the two sliders 4 are not on the same end face, that is, the sliding directions of the two sliders 4 are perpendicular to each other.

[0034] Specifically, when the two sliders 4 slide towards the end closest to the connecting block 9, the connecting block 9 can extend outward a greater distance, thus having a larger adjustment range to accommodate holes of special specifications. Furthermore, by controlling the position of the sliders 4 through the sliding connection, the sliders 4 can be positioned outside the center of the connecting block 9, allowing for more precise adjustment of the housing 1's position based on heat dissipation requirements. That is, by changing the position of the sliders 4 in the groove 101, the position of the connecting block 9 is controlled. If the left connecting block 9 is farther from the housing 1 and the right connecting block 9 is closer to the housing 1, then the position of the housing 1 on the mounting hole on the device will be to the right.

[0035] like Figures 1-4 As shown, the slider 4 has a first threaded hole 402, and a first bolt 5 that matches the first threaded hole 402 is threaded onto the slider 4. One end of the first bolt 5 passes through the first threaded hole 402 and contacts the bottom wall of the first limiting hole 102 to increase the friction between the slider 4 and the housing 1, thereby fixing the slider 4. Through the cooperation of the slider 4 and the first bolt 5, the slider 4 can be infinitely adjusted.

[0036] like Figures 1-4 As shown, the housing 1 has a plurality of evenly distributed first limiting holes 102. An elastic sheet 6 matching the first limiting hole 102 is fixedly connected to the slider 4. A first limiting protrusion 7 matching the first limiting hole 102 is fixedly connected to the elastic sheet 6. The elastic sheet 6 is elastic and has a downward force. The first limiting protrusion 7 can be completely located in the first limiting hole 102. The first limiting protrusion 7 being located in the first limiting hole 102 fixes the elastic sheet 6, thereby fixing the slider 4.

[0037] The first limiting hole 102 is generally a commonly used hole. In addition, if the slider 4 is fixed between two first limiting holes 102, and the first bolt 5 loosens after long-term use, the slider 4 will slide along the direction set by the slide groove 101. During the sliding process, the first limiting protrusion 7 will be located in one of the first limiting holes 102. In this way, the slider 4 will not continue to slide. That is, the first limiting hole 102 and the first limiting protrusion 7 can be used as a conventional hole setting, or as a remedy for the slider 4 sliding after the first bolt 5 becomes loose.

[0038] When using it, firstly, as Figures 1-5 As shown, loosen the first bolt 5 so that the slider 4 is slidably connected in the groove 101. First, fix the connecting block 9 to the equipment, and then slide the groove 101 in the slider 4 to tighten the connecting rope 8. Select the direction of the housing 1 offset according to the actual needs. After confirming the position of the housing 1, slide the slider 4 and tighten the first bolt 5 to achieve fixation and realize the installation of the housing 1.

[0039] The fan of this invention also prevents the housing 1 from directly contacting the equipment, creating a certain gap between them. When the fan is running, the connecting rope 8 provides shock absorption, reducing the possibility of the second bolt 11 becoming loose due to vibration.

[0040] like Figure 7 As shown, a shock-absorbing airbag 14 is provided on the back of the housing 1, and an air inlet 15 matching the shock-absorbing airbag 14 is provided on the housing 1. The shock-absorbing airbag 14 can inflate the air inlet 15, so that the air inlet 15 protrudes between the housing 1 and the equipment. The vibration generated by the fan during operation does not directly contact the equipment, thus reducing the generation of noise.

[0041] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0042] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
