[0023] This utility model embodiment provides a wear-resistant plastic fan blade, such as... Figure 1-5 As shown, the wear-resistant plastic fan blade includes: a fan blade 1; a mounting base 2 disposed on one side of the fan blade 1, the mounting base 2 and the fan blade 1 being fixedly connected; a fan blade main shaft 3 assembled on one side of the mounting base 2, the fan blade main shaft 3 being connected to the mounting base 2; and a filter screen 4 assembled on the mounting base 2, the filter screen 4 being located on one side of the fan blade 1, the filter screen 4 being used to filter impurities.

[0024] In this embodiment, during the use of the fan blade 1, the fan blade main shaft 3 rotates under the drive of a power source, such as a motor, thereby driving the fan blade 1 to rotate. During use, the filter screen 4 can effectively filter dust and impurity particles that impact the surface of the fan blade 1 with the airflow, preventing these dust and impurity particles from forming microscopic scratches on the surface of the fan blade 1, thereby slowing down the wear rate of the fan blade 1 and improving the overall wear resistance of the fan blade 1; at the same time, it reduces dust accumulation, reduces the vibration of the fan blade 1, and thus reduces the wear at the root of the fan blade 1, extending the service life of the fan blade 1.

[0025] In a further preferred embodiment of this utility model, the mounting base 2 and the fan blade main shaft 3 are threaded together with a screw 5, the mounting base 2 and the fan blade main shaft 3 are fixedly connected by the screw 5, and a screw ring 6 is fixedly installed at the end of the screw 5, the screw ring 6 is used to rotate the screw 5.

[0026] In this embodiment, the mounting base 2 and the fan blade main shaft 3 are connected by a screw 5, which facilitates the installation and fixing of the mounting base 2 and the fan blade main shaft 3. At the same time, the screw ring 6 provided at the end of the screw 5 provides convenience for installation and disassembly operations. Operators do not need to use additional tools and can directly tighten or loosen the screw 5 by rotating the screw ring 6, which greatly improves the efficiency of installation and disassembly and facilitates the maintenance and replacement of the fan blade 1.

[0027] In a further preferred embodiment of the present invention, a connecting groove 7 is provided on the mounting base 2, and a connecting block 8 is fixedly installed at the bottom of the filter screen 4, wherein the connecting block 8 and the connecting groove 7 are adapted to be connected.

[0028] In this embodiment, by opening a connecting groove 7 on the mounting base 2 and setting a matching connecting block 8 at the bottom of the filter screen 4, it is easy to connect the filter screen 4 and the mounting base 2 accordingly.

[0029] In a further preferred embodiment of the present invention, a fixing rod 9 is slidably mounted on the mounting base 2, the fixing rod 9 extends into the connecting groove 7 and passes through the connecting block 8, a threaded groove 10 is provided on the mounting base 2, and a threaded block 11 is threadedly mounted in the threaded groove 10, the threaded block 11 and one end of the fixing rod 9 abut against each other.

[0030] In this embodiment, after the connecting block 8 of the filter screen 4 is inserted into the connecting groove 7 of the mounting base 2, the sliding fixing rod 9 is slid through the connecting block 8, and then the threaded block 11 is screwed into the threaded groove 10 until the threaded block 11 abuts against one end of the fixing rod 9, thereby fixing the fixing rod 9 and completing the firm connection between the filter screen 4 and the mounting base 2. When disassembling, first unscrew the threaded block 11, and then slide the fixing rod 9 to disengage it from the connecting block 8, and the filter screen 4 can be removed. The operation is simple and does not require complicated tools and steps, making it convenient for the filter screen 4 to be regularly maintained, replaced or cleaned.

[0031] In a further preferred embodiment of the present invention, a positioning groove 13 is provided on the main shaft 3 of the fan blade, and a positioning rod 12 is fixedly installed on the mounting base 2, wherein the positioning rod 12 and the positioning groove 13 are adapted to be connected.

[0032] In this embodiment, when installing the fan blade 1 assembly, the positioning rod 12 on the mounting base 2 is aligned with the positioning groove 13 on the fan blade main shaft 3, and the positioning rod 12 is inserted into the positioning groove 13 to achieve initial positioning of the mounting base 2 and the fan blade main shaft 3. Then, the mounting base 2 and the fan blade main shaft 3 are further fixedly connected by connecting structures such as screws 5. During the operation of the fan blade 1, the cooperation between the positioning rod 12 and the positioning groove 13 can effectively resist the forces generated by wind, mechanical vibration and other factors, and prevent relative displacement between the mounting base 2 and the fan blade main shaft 3, thereby ensuring the stability and reliability of the entire fan blade 1 structure and reducing failures and wear caused by loose connections. When it is necessary to maintain or replace the fan blade 1, the structure of the positioning rod 12 and the positioning groove 13 also provides convenience. Operators can quickly and accurately disassemble and install the mounting base 2 according to the positional relationship between the positioning rod 12 and the positioning groove 13, which improves the efficiency of maintenance and replacement.

[0033] In a further preferred embodiment of the present invention, an abutment ring 14 is fixedly installed on the screw ring 6, and one side of the abutment ring 14 abuts against one side of the threaded block 11.

[0034] In this embodiment, during installation, after the initial fixing of the mounting base 2 and the fan blade main shaft 3 is completed by turning the screw ring 6 to drive the screw 5, the screw ring 6 is tightened further, so that the contact ring 14 gradually approaches the threaded block 11 until one side of the contact ring 14 and one side of the threaded block 11 come into contact. At this time, the contact ring 14 generates a certain resistance force on the threaded block 11, which plays an auxiliary fixing role. When disassembling, the screw ring 6 is turned in the opposite direction to move the contact ring 14 away from the threaded block 11 and release the resistance state. Then, the disassembly operation can be carried out according to the normal steps. The resistance of the contact ring 14 can play a certain limiting and fixing effect on the threaded block 11, reduce the probability of the threaded block 11 loosening, and ensure that the connection between the filter screen 4 and the mounting base 2 and the connection between the mounting base 2 and the fan blade main shaft 3 are always in a stable state.

[0035] In a further preferred embodiment of the present invention, the fan blade 1 is provided with a reinforcing rib 15, and the fan blade 1 is provided with a wear-resistant coating, the wear-resistant coating being polyurethane.

[0036] In this embodiment, the reinforcing rib 15 significantly improves the structural strength of the fan blade 1. When the fan blade 1 is subjected to wind force, centrifugal force, etc., the reinforcing rib 15 can share some of the stress, preventing the fan blade 1 from deforming or breaking due to excessive force, thereby ensuring that the fan blade 1 can operate stably and reliably and extending the service life of the fan blade 1. The polyurethane wear-resistant coating on the surface of the fan blade 1 has excellent wear resistance. During the operation of the fan blade 1, some dust, impurity particles, etc. will impact the surface of the fan blade 1 with the airflow. The wear-resistant coating can effectively resist the scratching and wear of these particles, reduce the micro-scratches on the surface of the fan blade 1, and reduce the wear rate of the fan blade 1. The reinforcing rib 15 and the polyurethane wear-resistant coating work together to form a comprehensive protection for the fan blade 1. The reinforcing rib 15 strengthens the strength of the fan blade 1 structurally, and the wear-resistant coating protects the fan blade 1 from wear from the surface. The two work together to greatly improve the wear resistance and service life of the fan blade 1.

[0037] In summary, compared with related technologies, this solution can effectively filter dust, reduce the impact and wear caused by dust on the surface of the fan blade 1, and thus extend the overall service life.
