[0002] Rugged fans typically refer to those with high strength, wear resistance, corrosion resistance, and high-temperature resistance. These fans are designed with the needs of various harsh environments in mind to ensure long-term stable operation.
[0003] The rotor and pump body of a robust blower need to be connected and fixed using pins. However, existing methods of connecting the rotor and pump body using pins generally use bolts for fixing. Since robust blowers vibrate during use, the nuts may fall off after a long period of use, causing the pins to fall off, which in turn affects the service life of the robust blower. To address the above problems, the inventor proposes a robust blower pin fixing device to solve the above problems. Utility Model Content

Then, the sliding sleeve is released, causing the spring to return to its original position, and the fixing ring to compress the fixing ball, causing the fixing ball to accumulate in the annular groove. This secures the first and second flanges, thus fixing the pin body and preventing it from falling off, improving the service life of the robust fan. The pin body and mounting base are bolted together, facilitating replacement of the pin body. By rotating the bidirectional screw, the threaded block slides within the base plate, causing the protective shell to move relative to each other, thus protecting the first connecting pipe, the second connecting pipe, and the pin body.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Example: Figure 1-7As shown, this utility model provides a robust fan pin fixing device, including a fan body 1. The fan body 1 includes a base plate 11. A motor 12 and a pump body 15 are respectively installed on the top surface of the base plate 11. A first connecting pipe 13 is fixedly provided on one side of the motor 12, and a first flange 14 is fixedly sleeved on the outer surface of the first connecting pipe 13. A second connecting pipe 16 is fixedly provided on one side of the pump body 15, and a second flange 17 is fixedly sleeved on the outer surface of the second connecting pipe 16. The first flange 14 and the second flange 17 are fitted together. The second flange 17 is movably inserted into the pin body 3. A mounting base 32 is installed on one side of the main body 3. A fixing tube 37 is fixedly installed on one side of the mounting base 32. The fixing tube 37 is movably inserted into the first flange 14. A fixing ball 38 is slidably installed inside the fixing tube 37. An insert rod 42 is movably inserted into the fixing tube 37. The fixing ball 38 is movably locked inside the insert rod 42. A limiting groove 371 is formed inside the fixing tube 37. A limiting rod 39 is fixedly installed on the outer surface of the fixing ball 38. The limiting rod 39 is slidably installed in the limiting groove 371. A sliding sleeve 33 is slidably fitted on the outer surface of the mounting base 32. A fixing ring 35 is fixedly installed inside the sliding sleeve 33. Ring 35 is slidably disposed within fixed tube 37. A spring 36 is fixedly connected between mounting base 32 and fixed ring 35. An annular groove 421 is formed within insertion rod 42, and fixed ball 38 is movably engaged within annular groove 421. By inserting pin body 3 and mounting base 32 into second flange 17, mounting base 32 is forced into first flange 14. Then, insertion rod 42 is inserted into fixed tube 37. At this time, fixed ball 38 abuts against insertion rod 42, pushing sliding sleeve 33 and causing fixed ring 35 to slide on the outer surface of fixed tube 37, compressing spring 36. Then, insertion rod 42 is pushed again. This causes the fixed ball 38 to slide the limiting rod 39 in the limiting groove 371, allowing the insertion rod 42 to be inserted into the fixed tube 37. Then, the sliding sleeve 33 is released, causing the spring 36 to return to its original position. This causes the fixing ring 35 to press the fixed ball 38, which is then pressed into the ring groove 421. This allows the first flange 14 and the second flange 17 to be secured, thereby fixing the pin body 3 and preventing it from falling off. This improves the service life of the robust fan. The pin body 3 and the mounting base 32 are installed with bolts, making it easy to replace the pin body 3.
[0022] The mounting base 32 has a groove 321, and the sliding sleeve 33 has a fixed slider 34. The slider 34 is slidably disposed in the groove 321. A first limiting ring 31 is fixedly disposed on one side of the pin body 3. The first limiting ring 31 is movably disposed in the second flange 17. A second limiting ring 4 is fixedly disposed on one side of the insertion rod 42. The second limiting ring 4 is movably disposed in the first flange 14. A top plate 41 is slidably inserted into the second limiting ring 4.
[0023] By adopting the above technical solution, by pushing the top plate 41, the sliding sleeve 33 slides in the mounting base 32, and the slider 34 slides in the groove 321, thereby facilitating the sliding of the fixed ball 38.
[0024] A bidirectional lead screw 2 is rotatably mounted inside the base plate 11. A turntable 21 is fixedly mounted at one end of the bidirectional lead screw 2. A protective shell 22 is slidably mounted on the top surface of the base plate 11. A threaded block 23 is fixedly mounted on the bottom surface of the protective shell 22. The threaded block 23 is threadedly mounted on the outer surface of the bidirectional lead screw 2.
[0025] By adopting the above technical solution, the threaded block 23 slides inside the base plate 11 by rotating the bidirectional lead screw 2, and drives the protective shell 22 to move relative to each other, thereby protecting the first connecting pipe 13, the second connecting pipe 16 and the pin body 3.
[0026] Working principle: First, by inserting the pin body 3 and the mounting base 32 into the second flange 17, the mounting base 32 is forced into the first flange 14. Then, the insertion rod 42 is inserted into the fixed tube 37. At this time, the fixed ball 38 abuts against the insertion rod 42. Next, the sliding sleeve 33 is pushed, causing the fixing ring 35 to slide on the outer surface of the fixed tube 37 and compressing the spring 36. Then, the insertion rod 42 is pushed again, causing the fixing ball 38 to drive the limiting rod 39 to slide in the limiting groove 371, so that the insertion rod 42 can be inserted into the fixed tube 37. Then, the sliding sleeve 33 is released, causing the spring 36 to return to its original position, thus allowing the fixed tube 37 to be inserted. The ring 35 presses the fixed ball 38, causing the fixed ball 38 to accumulate in the ring groove 421, thereby fixing the first flange 14 and the second flange 17, and thus fixing the pin body 3, preventing the pin body 3 from falling off, and improving the service life of the robust fan. The pin body 3 and the mounting base 32 are installed by bolts, which makes it easy to replace the pin body 3. By rotating the bidirectional screw 2, the threaded block 23 slides in the base plate 11 and drives the protective shell 22 to move relative to each other, thereby protecting the first connecting pipe 13, the second connecting pipe 16 and the pin body 3.
[0027] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
