Description

Technical Field

[0001] This application relates to the field of industrial ceiling fan technology, and in particular to a noise-reducing tail fin for a large industrial ceiling fan that is easy to disassemble and install and provides shock absorption. Background Technology

[0002] Industrial fans can most efficiently drive a large amount of air movement, generating a huge air volume and creating a moving, circulating airflow field in the space. They can effectively regulate the air circulation problem in industrial production workshops. The area blown by an industrial fan is directly related to the diameter of the fan. Large industrial fans have a large coverage area and are easy to clean, solving the problems of high noise and high energy consumption.

[0003] The published patent, CN215109665U, describes a noise-reducing tail fin for a large industrial ceiling fan. The tail fin includes a docking plate and a fan blade body. The docking plate has an internal mounting cavity, and the end of the fan blade body extends into the mounting cavity. A tail fin body is welded to the end of the docking plate away from the fan blade body. A threaded hole is located at the center of the docking plate, and a fixing bolt is installed in the threaded hole. A limiting post is fixedly connected below the fixing bolt. The combination of the limiting post, fixing bolt, and mounting base facilitates quick installation and disassembly of the docking plate and fan blade body, improving the efficiency of replacing and maintaining the noise-reducing tail fin. Simultaneously, a vibration damping device is installed inside the mounting cavity to reduce vibrations generated during fan operation, further enhancing the noise reduction effect of the tail fin.

[0004] When implementing the above device, the fixing bolts are removed, and then a disassembly rod that matches the disassembly hole is inserted into the disassembly hole. The mounting plate is pressed down to disengage it from the upper limit slot, making it easier to pull out the fan blade body and improving disassembly efficiency. The above device relies on the removal of the fixing bolts to disassemble the device. However, frequent removal of the bolts will cause their threads to be easily damaged, resulting in insufficient firmness when tightening them later. In addition, auxiliary tools must be used to complete the disassembly, which is not convenient. Utility Model Content

[0005] In view of the shortcomings of the prior art, this utility model provides a large industrial ceiling fan noise reduction tail fin that is easy to disassemble and install and has shock absorption properties, which overcomes the shortcomings of the prior art and aims to solve the problems in the background art.

[0006] To achieve the above objectives, this application adopts the following technical solution: a large industrial ceiling fan noise-reducing tail fin that is easy to disassemble and install and provides shock absorption, comprising a mounting base. A circular hole is formed at the bottom of the mounting base. Two guide grooves are symmetrically formed on the inner wall of the circular hole. A receiving groove is formed at the top of the circular hole. A magnetic sheet is fixedly connected to the inner top of the receiving groove. One end of a spring is fixedly connected to the bottom of the magnetic sheet. A pressure plate is fixedly connected to the other end of the spring. A second magnetic sheet is fixedly installed on the top of the pressure plate. Two positioning components are symmetrically fixedly assembled along the outer edge of the mounting base. The positioning assembly includes a protective cover fixedly installed on the outer edge of the mounting base. A rod is slidably connected to the inner wall of the protective cover. A first washer is fixedly installed on the outer edge of the rod. One end of a second spring is fixedly connected to the outer side of the first washer. The other end of the second spring is fixedly connected to the second washer. A connecting rod is slidably connected to the inner wall of the circular hole. Two sliders are symmetrically fixedly mounted on the outer edge of the connecting rod. A mounting plate is fixedly installed at the bottom of the connecting rod. Five fan blades are evenly distributed on the outer edge of the mounting plate. A tail fin body is fixedly installed on the side of the five fan blades away from the mounting plate.

[0007] In a preferred embodiment, the outer diameter of the pressure plate is adapted to the inner wall diameter of the receiving groove, and the two adjacent surfaces of the magnetic sheet two and the magnetic sheet one are the same magnetic pole.

[0008] By adopting the above technical solution, when the connecting rod pushes the pressure plate upward, it can ensure that the pressure plate slides stably on the inner wall of the receiving groove. Then, the repulsive force between the magnetic sheet two and the magnetic sheet one can be used to push the pressure plate to reset. This ensures that the top of the connecting rod will not rub against the bottom of the pressure plate, thereby reducing the vibration force during operation.

[0009] In a preferred embodiment, the second gasket has a sliding hole in the middle that matches the insertion rod, the insertion rod is slidably connected to the inner wall of the sliding hole, and the outer diameter of the first gasket matches the inner diameter of the protective cover.

[0010] By adopting the above technical solution, the pulling rod can drive the pad one to slide on the inner wall of the protective cover, thereby facilitating the compression spring two to contract in the inner cavity of the mounting base.

[0011] In a preferred embodiment, a pull ring is fixedly installed at one outer end of the insertion rod, and insertion holes are provided on the inner walls of both the mounting base and the connecting rod. The end of the insertion rod away from the pull ring is inserted into the inner wall of the insertion hole.

[0012] By adopting the above technical solution, it is easy to pull the insertion rod to move on the inner wall of the protective cover, thereby making it easier to adjust the end of the insertion rod away from the pull ring to disengage from the inner wall of the insertion hole, and thus making it easier to remove the connecting rod from the inner wall of the round hole.

[0013] In a preferred embodiment, the top of the mounting base is fixedly connected to the output shaft of the motor, and the top of the mounting base is symmetrically threaded with two lifting rings.

[0014] By adopting the above technical solution, the motor can drive the five fan blades to rotate using the mounting base, and the two lifting rings make it easy to use with the lifting rope to hoist the device to a high place, ensuring that it will not easily fall off during operation.

[0015] In a preferred embodiment, the outer diameter of the connecting rod is adapted to the inner diameter of the circular hole, and the two sliders are slidably connected to the inner walls of the two guide grooves, which are connected to the inner walls of the receiving groove.

[0016] By adopting the above technical solution, no gap will be generated after the connecting rod is slidably installed into the inner wall of the round hole, thus ensuring that it will not easily shake, and the two sliders can slide along the two guide grooves into the inner cavity of the receiving groove.

[0017] In a preferred embodiment, the inner bottom of the receiving groove has two symmetrical slots that are adapted to the shape of the slider, and the two slots and the two guide grooves are arranged in a cross shape.

[0018] By adopting the above technical solution, after the two sliders slide into the inner cavity of the receiving groove, the connecting rod can rotate the two sliders by 90 degrees, thereby installing the two sliders onto the inner wall of the two slots and realizing a stable connection between the connecting rod and the mounting base.

[0019] In a preferred embodiment, the outer edges of the mounting plate, fan blades, and tail fin body are all coated with a galvanized layer.

[0020] By adopting the above technical solutions, the aesthetics of the mounting plate, fan blades, and tail fin body can be guaranteed, thereby ensuring that they will not easily rust.

[0021] The beneficial effects of this application are:

[0022] 1. This large industrial ceiling fan noise reduction tail fin, which is easy to disassemble and shock-absorbing, works by inserting a connecting rod into the inner wall of a circular hole, allowing the slider to slide along the inner wall of the guide groove into the inner cavity of the receiving groove. At this point, the connecting rod can be pushed to move the pressure plate upward until the slider is fully inserted into the inner cavity of the receiving groove. Then, the connecting rod can be rotated to offset the positions of the two sliders from the two guide grooves, thus locking them into the inner walls of the two slots. Then, the pull ring is released, and the force of the spring pushes the pad and the end of the insert rod away from the pull ring to move and insert them into the inner wall of the insertion hole. This stabilizes the connecting rod in the inner wall of the circular hole. The pull ring drives the insert rod to disengage from the inner wall of the connecting rod, and the connecting rod can be rotated to remove it from the inner wall of the circular hole. This facilitates the disassembly and maintenance of the fan blade and tail fin body, which can be done manually without the use of any auxiliary tools.

[0023] 2. This type of easy-to-disassemble and shock-absorbing noise-reducing tail fin for large industrial ceiling fans uses a spring-loaded pressure plate to abut against two sliders that are locked to the inner wall of the slot, ensuring that they do not easily detach. At the same time, the repulsive force between the magnetic plate and the magnetic plate can push the pressure plate to reset, thus ensuring that the top of the connecting rod does not rub against the bottom of the pressure plate, thereby reducing the vibration force during operation.

[0030] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0031] Reference Figure 1-5 A noise-reducing tail fin for a large industrial ceiling fan that is easy to assemble and disassemble and provides shock absorption includes a mounting base 1. The mounting base 1 has a circular hole 3 at its bottom. Two guide grooves 4 are symmetrically formed on the inner wall of the circular hole 3. A receiving groove 5 is formed at the top of the circular hole 3. A magnetic sheet 6 is fixedly connected to the inner top of the receiving groove 5. One end of a spring 7 is fixedly connected to the bottom of the magnetic sheet 6. A pressure plate 8 is fixedly connected to the other end of the spring 7. A second magnetic sheet 9 is fixedly installed on the top of the pressure plate 8. Two positioning components 10 are symmetrically fixedly mounted on the outer edge of the mounting base 1. Each positioning component 10 includes a protective cover 1001 fixedly mounted on the outer edge of the mounting base 1 to prevent... The inner wall of the protective cover 1001 is slidably connected to the insert rod 1002. The outer edge of the insert rod 1002 is fixedly installed with a first gasket 1003. The outer side of the first gasket 1003 is fixedly connected to one end of the second spring 1004. The other end of the second spring 1004 is fixedly connected with a second gasket 1005. The inner wall of the round hole 3 is slidably connected to the connecting rod 11. Two sliders 12 are symmetrically fixedly assembled on the outer edge of the connecting rod 11. The bottom of the connecting rod 11 is fixedly installed with a mounting plate 13. Five fan blades 14 are evenly distributed on the outer edge of the mounting plate 13. The tail wing body 15 is fixedly installed on the side of the five fan blades 14 away from the mounting plate 13.

[0032] See Figure 5 The outer diameter of the pressure plate 8 is matched with the inner diameter of the receiving groove 5. The two surfaces of the magnetic sheet 9 and the magnetic sheet 6 that are close to each other are the same magnetic pole. This ensures that when the connecting rod 11 pushes the pressure plate 8 to move upward, the pressure plate 8 can slide stably on the inner wall of the receiving groove 5. Then, the repulsive force between the magnetic sheet 9 and the magnetic sheet 6 can be used to push the pressure plate 8 to reset. This ensures that the top of the connecting rod 11 will not rub against the bottom of the pressure plate 8, thereby reducing the vibration force during operation.

[0033] See Figure 4 The second gasket 1005 has a sliding hole in the middle that matches the insertion rod 1002. The insertion rod 1002 is slidably connected to the inner wall of the sliding hole. The outer diameter of the first gasket 1003 matches the inner diameter of the protective cover 1001, so that pulling the insertion rod 1002 can drive the first gasket 1003 to slide on the inner wall of the protective cover 1001, thereby facilitating the compression spring 1004 to contract in the inner cavity of the mounting base 1.

[0034] See Figure 3 and Figure 4A pull ring 1006 is fixedly installed on one side of the insertion rod 1002. Insertion holes are opened on the inner walls of the mounting base 1 and the connecting rod 11. The end of the insertion rod 1002 away from the pull ring 1006 is inserted into the inner wall of the insertion hole, which makes it easy to pull the insertion rod 1002 to move on the inner wall of the protective cover 1001, thereby making it easy to adjust the end of the insertion rod 1002 away from the pull ring 1006 to disengage from the inner wall of the insertion hole, thereby making it easy to remove the connecting rod 11 from the inner wall of the round hole 3.

[0035] See Figure 1 - Figure 3 The top of the mounting base 1 is fixedly connected to the output shaft of the motor 16. The top of the mounting base 1 has two symmetrical threaded connections for lifting rings 2, which allows the motor 16 to rotate and drive the five fan blades 14 to rotate. The two lifting rings 2 also make it easy to use a lifting rope to hoist the device to a high place, ensuring that it will not easily fall off during operation.

[0036] See Figure 2 and Figure 5 The outer diameter of the connecting rod 11 is matched with the inner diameter of the circular hole 3. The two sliders 12 are slidably connected to the inner walls of the two guide grooves 4. The two guide grooves 4 are connected to the inner walls of the receiving groove 5, so that no gap will be generated after the connecting rod 11 is slidably installed to the inner wall of the circular hole 3, thus ensuring that it will not easily shake. The two sliders 12 can slide along the two guide grooves 4 to the inner cavity of the receiving groove 5.

[0037] See Figure 5 The inner bottom of the receiving groove 5 has two symmetrical slots that are adapted to the shape of the slider 12. The two slots and the two guide grooves 4 are arranged in a cross shape, so that after the two sliders 12 slide into the inner cavity of the receiving groove 5, the connecting rod 11 can be rotated to drive the two sliders 12 to rotate 90 degrees, and then the two sliders 12 can be installed on the inner wall of the two slots to achieve a stable connection between the connecting rod 11 and the mounting base 1.

[0038] See Figure 1 - Figure 3 The outer edges of the mounting plate 13, fan blade 14 and tail fin body 15 are coated with a galvanized layer, which ensures the aesthetic appearance of the outer edges of the mounting plate 13, fan blade 14 and tail fin body 15, and thus ensures that they will not easily rust.

[0039] Working principle: When using this device, firstly, pull the two pull rings 1006 to move the insertion rod 1002 until the end of the insertion rod 1002 away from the pull rings 1006 disengages from the inner wall of the round hole 3. Then, the connecting rod 11 can be inserted into the inner wall of the round hole 3, and the slider 12 slides along the inner wall of the guide groove 4 into the inner cavity of the receiving groove 5. At this time, the connecting rod 11 can be pushed to push the pressure plate 8 upward until the slider 12 is completely inserted into the inner cavity of the receiving groove 5. Then, the connecting rod 11 can be rotated to make the two sliders 12 offset from the two guide grooves 4, and thus engage with the inner wall of the two slots. At the same time, the restoring force of the spring 7 can push the pressure plate 8 to abut against the two sliders 12 engaged with the inner wall of the slot. To ensure that it will not easily detach, the repulsive force between magnetic sheet 2 9 and magnetic sheet 1 6 can be used to push the pressure plate 8 back to its original position. This ensures that the top of the connecting rod 11 will not rub against the bottom of the pressure plate 8, thereby reducing the vibration force during operation. Then, the pull ring 1006 can be released, and with the force of spring 2 1004, the pad 1003 and the insertion rod 1002 will be moved away from the pull ring 1006 and inserted into the inner wall of the insertion hole. This will stably position the connecting rod 11 on the inner wall of the round hole 3. The pull ring 1006 will drive the insertion rod 1002 to detach from the inner wall of the connecting rod 11, and the connecting rod 11 can be rotated to be removed from the inner wall of the round hole 3, thus facilitating the disassembly and maintenance of the fan blade 14 and the tail fin body 15.
