[0035] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0036] like Figures 1-8 As shown, an axial flow fan bushing includes a connecting plate 101 and a bushing sleeve 102. The bushing sleeve 102 is connected to the connecting plate 101. The connecting plate 101 has a bushing hole 1021 corresponding to the bushing sleeve 102. The connecting plate 101 has multiple threaded holes. The connecting plate 101 is fixed to the motor by inserting screws into the threaded holes. The bushing sleeve 102 is provided with two connecting cylinders 103. The cross-section of the connecting cylinder 103 parallel to the surface of the connecting plate 101 is a semi-circular structure. The connecting cylinder 103 is detachably connected to the bushing sleeve 102.

[0037] Furthermore, the connecting cylinder 103 is provided with a first through cavity, which is arranged along the axial direction of the connecting cylinder 103. The bushing 102 is provided with a second through cavity corresponding to the first through cavity, which is arranged along the axial direction of the bushing 102. The first through cavity is filled with metal powder, which is copper powder or aluminum powder. The high thermal conductivity of the metal is used to quickly conduct the heat inside the bushing to the outside.

[0038] Furthermore, the connecting cylinder 103 is provided with heat dissipation fins 104, which have a spiral structure. The heat dissipation fins 104 on the two connecting cylinders 103 cooperate with each other to form a complete spiral structure. Compared with ordinary in-line fins, the spiral design can guide the airflow to spiral upward along the surface of the bushing, increase the contact time and area between the airflow and the fins, and greatly improve the heat dissipation efficiency.

[0039] The heat dissipation fin 104 is provided with a first connecting block 105, and the connecting cylinder 103 is provided with a first connecting groove corresponding to the first connecting block 105. Through the cooperation of the first connecting block 105 and the first connecting groove, the heat dissipation fin 104 can be easily disassembled and assembled, making the cleaning of the heat dissipation fin 104 more convenient and ensuring the heat dissipation effect of the heat dissipation fin 104.

[0040] The first connecting block 105 is provided with a third protrusion 1051, the inner wall of the first connecting groove is provided with a groove, and the side wall of the third protrusion 1051 is provided with a rubber pad. The cooperation between the third protrusion 1051 and the groove improves the connection effect between the first connecting block 105 and the first connecting groove, and prevents the heat dissipation fins 104 from being thrown out during the operation of the fan. The rubber pad increases the friction between the third protrusion 1051 and the groove, further ensuring the stability of the heat dissipation fins 104 in use.

[0041] Furthermore, the bushing 102 is provided with a first movable groove, and a connecting rod 111 is provided in the first movable groove. The connecting cylinder 103 is provided with a second connecting groove corresponding to the connecting rod 111. The connecting rod 111 is provided with a second connecting block 1111. The second connecting block 1111 extends out from the first movable groove and is provided with a connecting ring 106.

[0042] The bushing 102 is provided with a first protrusion 107, and the connecting cylinder 103 is provided with a second protrusion 108. The first protrusion 107 is provided with a fixing plate 109, and the fixing plate 109 is provided with a fixing block 110. The second protrusion 108 is provided with a fixing groove corresponding to the fixing block 110. The fixing block 110 is provided with a slider 1101, and the inner wall of the fixing groove is provided with a sliding groove corresponding to the slider 1101. The fixing block 110 is made of magnet, and the second protrusion 108 is made of ferromagnetic metal. By utilizing the magnetic force of the fixing block 110 and the fixing groove, the connection effect between the fixing block 110 and the fixing groove is improved, ensuring the stability of the connection between the connecting cylinder 103 and the bushing 102.

[0043] The fixed plate 109 is provided with a guide rod 112, the first protrusion 107 is provided with a guide groove, the guide rod 112 is inserted into the guide groove, and a limiting plate 1121 is provided at one end of the guide rod 112 to prevent the guide rod 112 from completely coming out of the guide groove.

[0044] The connecting ring 106 is provided with a push plate 1061, the push plate 1061 is provided with a first insert plate 1062, the first protrusion 107 is provided with a first slot corresponding to the first insert plate 1062, the fixing plate 109 is provided with a second insert plate 113, the first insert plate 1062 is provided with a through groove corresponding to the second insert plate 113; the first movable groove is provided with a second slot corresponding to the second insert plate 113, and the first slot and the second slot are connected.

[0045] When it is necessary to apply oil to the inside of the bushing, pull the fixing plate 109 away from the first protrusion 107. The fixing plate 109 drives the fixing block 110 to move. The fixing block 110 moves out of the fixing groove. At the same time, the second insert plate 113 moves out of the through groove and pushes the push plate 1061 towards the connecting plate 101. The push plate 1061 drives the connecting ring 106 to move. The connecting rod 111 moves out of the second connecting groove. The connecting sleeve can be moved directly along the radial direction of the bushing 102 to remove the two connecting sleeves, which makes it convenient to apply oil to the inner wall of the connecting sleeve and the motor output shaft.

[0046] After the oiling process is completed, the connecting cylinder 103 is pushed radially towards the motor output shaft along the bushing 102. The connecting cylinder 103 abuts against the bushing 102. After aligning the second connecting groove and the first movable groove, the push plate 1061 is pushed towards the connecting cylinder 103. The push plate 1061 drives the connecting ring 106 to move. The connecting rod 111 extends out from the first movable groove and inserts into the second connecting groove. The first insert plate 1062 is inserted into the first slot. The through groove and the second slot are aligned. The fixing plate 109 is pushed towards the first protrusion 107. The fixing block 110 moves into the fixing groove. The second insert plate 113 is inserted into the second slot. At the same time, the second insert plate 113 is inserted into the through groove to fix the first insert plate 1062, keeping the connecting rod 111 in the state of extending out of the first movable groove, ensuring the stability of the connection between the connecting cylinder 103 and the bushing 102.
