[0019] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0020] Example

[0021] like Figure 1 - Figure 5 As shown, a fan box that facilitates the installation and fixing of a fan includes a fan box body 1, a fan body 4 is provided inside the fan box body 1, and a filter cover 2 is fixedly installed at one end of the fan box body 1 near the fan body 4. The filter cover 2 has multiple annularly distributed filter holes 3. The filter cover 2 is used to filter the air drawn into the fan box body 1 by the fan body 4.

[0022] The bottom of the fan body 4 is fixedly connected to the card seat 6 by a connector. The connector includes two support plates 5 set on the bottom of the fan body 4 and the upper surface of the card seat 6. The two support plates 5 are symmetrically arranged, and the two ends of the support plates 5 are fixedly connected to the fan body 4 and the card seat 6 respectively, so as to fix the fan body 4 and the card seat 6 to form an integral structure.

[0023] A set of pin holes 7 are opened on both sides of the card holder 6. Limiting plates 8 are integrally formed on both sides of the bottom wall of the card holder 6. A fixing seat 9 is fixedly connected to the bottom wall of the inner cavity of the fan housing 1. A sliding groove 10 is opened on the upper surface of the fixing seat 9. Limiting grooves 11 that are adapted to the size of the limiting plates 8 are opened on both sides of the inner wall of the sliding groove 10. A set of receiving holes 12 are opened on the side wall of the sliding groove 10 above the limiting grooves 11. A spring 13 is installed in each receiving hole 12. A fixed end of the spring 13 near the opening of the receiving hole 12 is fixedly installed. A slider 14 can slide within the receiving hole 12. A locking shaft 17 is fixedly connected to the end of the slider 14 away from the spring 13. The diameter of the pin hole 7 is adapted to the diameter of the locking shaft 17. The inner cavity depth of the pin hole 7 is less than the length of the locking shaft 17 outside the receiving hole 12 when the spring 13 is in the extended state. After the locking shaft 17 is inserted into the pin hole 7, the spring 13 is in a partially compressed state and can resist the locking shaft 17 under the action of elastic force, thereby increasing the stability of the connection between the locking shaft 17 and the pin hole 7.

[0024] A sealing plate is provided at one end of the slide 10 near the air filter cover 2. When the card seat 6 slides along the slide 10 to fit with the sealing plate, the locking shaft 17 and the pin hole 7 are aligned, which facilitates the quick alignment of the locking shaft 17 and the pin hole 7 and facilitates the quick installation of the fan body 4.

[0025] An adjustment device for adjusting the position of the slider 14 is also provided on the receiving hole 12. An adjustment hole 15 is provided on the top wall of the receiving hole 12. The adjustment device is an adjustment rod 16 that is slidably disposed in the adjustment hole 15. The bottom end of the adjustment rod 16 is fixed to the upper surface of the slider 14, and the top end of the adjustment rod 16 extends to the top of the fixed seat 9 to form an adjustment handle. When it is necessary to disassemble and repair the fan body 4, the adjustment rod 16 can be slid to both sides along the adjustment hole 15 to compress the spring 13 and thus slide the locking shaft 17 into the receiving hole 12 until the end of the locking shaft 17 disengages from the pin hole 7. At this time, the user can slide the card seat 6 away from the end of the slide groove 10 away from the sealing plate to remove the card seat 6 from the slide groove 10 and complete the disassembly of the fan body 4.

[0026] It should be noted that this fan box, which facilitates the installation and fixing of the fan, has the fan body 4 fixed to the mounting bracket 6 by the support plate 5. The bottom wall of the fan box 1 is fixedly connected to the mounting base 9. When installing the fan body, firstly, the adjusting rod 16 slides along the adjusting hole 15, driving the slider 14 to slide into the receiving hole 12, compressing the spring 13 to contract, so that the locking shaft 17 slides completely into the receiving hole 12. Then, one end of the mounting bracket 6 is aligned with the slide groove 10 opened on the mounting base 9, and the mounting bracket 6 is slid into the slide groove 10 until the pin holes 7 opened on both sides of the mounting bracket 6 slide to be aligned with the locking shaft 17. At this time, the user can open the locking shaft 17 and use the elastic force of the spring 13 to push the end of the locking shaft 17 away from the spring 13 into the pin hole 7, connecting the mounting bracket 6 and the mounting base 9 together, thereby realizing the quick installation of the fan body 4 and the fan box 1, which is convenient for the user.

[0027] When it is necessary to disassemble the fan body 4, the adjusting rod 16 can be slid along the adjusting hole 15 to both sides to compress the spring 13 and thus slide the locking shaft 17 into the receiving hole 12 until the end of the locking shaft 17 disengages from the pin hole 7. At this time, the user can slide the card seat 6 away from the end of the slide groove 10 away from the sealing plate and remove the card seat 6 from the slide groove 10 to complete the disassembly of the fan body 4. This avoids the problem of the existing method of fixing with multiple bolts, which is not only time-consuming and laborious to install, but also causes the bolts to rust after a long time, making it difficult to disassemble the fan body 4.

[0028] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
