Detailed implementation manners
[0024] The following will disclose multiple implementation manners of the present utility model with illustrations. For the sake of clear description, many physical details will be described together in the following narrative. However, it should be understood that these physical details are not used to limit the present utility model. That is to say, in some implementation manners of the present utility model, these physical details are unnecessary. In addition, for the sake of simplifying the illustrations, some conventional structures and components will be shown in a simple schematic manner in the illustrations.
[0025] Please refer to Figure 1 , Figure 2 , a pulley for facilitating heat dissipation of the present utility model includes a pulley body 1. A first ventilation groove 2 is provided on the outer surface of the pulley body 1. The first ventilation groove 2 is arranged on the outer surface of the pulley body 1. When the pulley body 1 is running, air flow will flow along the first ventilation groove 2, thereby accelerating the heat dissipation of the pulley. A plurality of threaded grooves 3 are provided on both the front and rear sides of the pulley body 1, and connecting blocks 4 are provided on both the front and rear sides of the pulley body 1.
[0026] In this embodiment, a second ventilation groove 7 is formed on the outer surface of each connecting block 4. During the connection of the connecting block 4 to the pulley body 1, the second ventilation groove 7 communicates with the internal cavity of the pulley body 1. A first connecting rod 9 is provided inside the pulley body 1, and a first fan blade 10 is fixedly installed on the outer surface of the first connecting rod 9. One end of the first connecting rod 9 is a hexagonal plug, and the outer surface of the first connecting rod 9 is inserted into both connecting blocks 4. The hexagonal plug can be inserted and fixed to the corresponding connecting block 4. A connecting shaft 8 is fixedly installed at one end of one connecting block 4 away from the first connecting rod 9. Specifically, the pulley body 1 can be connected to other components through the connecting shaft 8. When the connecting block 4 rotates, it drives the first connecting rod 9 to rotate, and the rotation of the first connecting rod 9 drives the first fan blade 10 to start rotating.
[0027] In this embodiment, a first slot 5 is formed on the outer surface of each connecting block 4, and the inner wall of each first slot 5 communicates with the corresponding threaded groove 3. Specifically, the connecting block 4 is pressed on both sides of the pulley body 1, and then the angle of the connecting block 4 is adjusted so that the first slot 5 and the corresponding threaded groove 3 are on the same central axis.
[0028] In this embodiment, a bolt 6 is threadedly connected to the inner wall of each threaded groove 3, and the outer surface of each bolt 6 is inserted into the corresponding first slot 5. Specifically, after adjusting the position of the connecting block 4, the bolt 6 is inserted into the corresponding first slot 5, and the bolt 6 is rotated to connect it to the corresponding threaded groove 3, thereby completing the fixation of the connecting block 4 and the pulley body 1. At this time, the rotation of the pulley body 1 drives the connecting block 4 carrying the first fan blade 10 to start rotating, and the heat in the internal cavity of the pulley body 1 is dissipated through the rotation of the first fan blade 10.
[0029] As Figure 1 、 Figure 3 、 Figure 4 , a second fan blade 11 is inserted at one end of the first connecting rod 9 away from the connecting shaft 8. The second fan blade 11 is arranged outside the pulley body 1. Two second slots 18 are formed on the side of the second fan blade 11 away from the connecting block 4. Specifically, by installing the second fan blade 11, when the pulley body 1 rotates, it drives the second fan blade 11 to rotate simultaneously, and the rotation of the second fan blade 11 accelerates the flow of heat outside the pulley body 1, thereby accelerating the heat dissipation of the outside of the pulley.
[0030] In this embodiment, a third slot 12 is formed on the outer surface of the first connecting rod 9. Two planes are formed on the outer surface of one end of the first connecting rod 9, and the third slot 12 is arranged on the planes. A connecting plate 13 is inserted into the inner wall of the third slot 12. Specifically, after the second fan blade 11 is installed, the connecting plate 13 is inserted into the third slot 12 to limit the second fan blade 11.
[0031] As Figure 4 , Figure 6 shown, two fixing slots 14 are formed inside the connecting plate 13. The opening directions of the fixing slots 14 face the corresponding connecting plate 13. A push block 16 is slidably connected to the inner wall of each fixing slot 14. By pushing the push block 16, the push block 16 can slide horizontally along the corresponding fixing slot 14. One end of each push block 16 close to the second fan blade 11 is fixedly connected with an insertion rod 17. By connecting the insertion rod 17 with the corresponding push block 16, the push block 16 can drive the corresponding insertion rod 17 to slide horizontally along the fixing slot 14. The outer surface of each insertion rod 17 is inserted into the corresponding second slot 18. Specifically, the connecting plate 13 can be fixed on the second fan blade 11 through the insertion between the insertion rod 17 and the corresponding second slot 18.
[0032] In a preferred embodiment, a spring 15 is arranged inside each fixing slot 14. One end of each spring 15 close to the corresponding push block 16 is fixedly connected with the corresponding push block 16, and the other end is fixedly connected with the corresponding fixing slot 14. Specifically, during the installation process of the connecting plate 13, the insertion rod 17 will first be squeezed by the second fan blade 11, and then the insertion rod 17 will push the corresponding push block 16 to compress the corresponding spring 15 until the insertion rod 17 on the connecting plate 13 and the corresponding second slot 18 are on the same central axis. At this time, the spring 15 will push the corresponding insertion rod 17 under its resilience force to make it enter the corresponding second slot 18, so as to complete the quick fixing of the second fan blade 11.
