[0019] See also Figure 1-Figure 3 The utility model provides a rotating buckle fixing device for the air nozzle of a turbofan device, comprising a motor housing 1, a fixing seat 2 is integrally formed at one end of the motor housing 1, a connecting sleeve 3 is arranged on the side of the fixing seat 2 away from the motor housing 1, an end of the connecting sleeve 3 close to the motor housing 1 is plugged into the inner cavity of the motor housing 1, a positioning assembly is arranged between the connecting sleeve 3 and the fixing seat 2, the connecting sleeve 3 is detachably mounted together through the positioning assembly, the positioning assembly comprises a mounting seat 5 fixedly mounted at one end of the connecting sleeve 3, corresponding through holes 6 are opened on the surfaces of the mounting seat 5 and the fixing seat 2, the mounting seat 5 and the fixing seat 2 are tightened and fixed together by bolts and the through holes 6.

[0020] By setting the positioning component, the connecting sleeve 3 can be installed and fixed on one end of the motor housing 1. During installation, the user can insert one end of the connecting sleeve 3 into one end of the motor housing 1 so that the surface of the fixing seat 2 and the mounting seat 5 fit together. Then the user can use bolts to penetrate the through holes 6 on the surface of the mounting seat 5 and tighten the through holes 6 on the surface of the fixing seat 2 to fix the mounting seat 5 on one side of the fixing seat 2, and then install the connecting sleeve 3 and the motor housing 1 together by bolt connection.

[0021] In some other embodiments, the connection sleeve 3 and the motor housing 1 may be fixed together by snapping, gluing, or ultrasonic positioning.

[0022] Preferably, a countersunk hole 9 for hiding the bolt is provided on one side of the mounting seat 5, and the countersunk hole 9 is arranged corresponding to the through hole 6. Through the arrangement of the countersunk hole 9, after the mounting seat 5 and the fixing seat 2 are locked together by tightening the bolt, one end of the bolt will be hidden in the inner cavity of the countersunk hole 9 to ensure the flatness of the surface of the mounting seat 5, and prevent the subsequent nozzle body 4 from being unable to fit the surface of the mounting seat 5 due to the protrusion of one end of the bolt.

[0023] Among them, a guide component for aligning the mounting seat 5 with the fixing seat 2 is also arranged between the mounting seat 5 and the fixing seat 2, and the guide component includes a guide plug plate 7 fixedly installed on one side of the mounting seat 5, and a guide slot 8 is opened on one side of the fixing seat 2 and at a corresponding position of the guide plug plate 7, and one side of the guide plug plate 7 is inserted into the inner cavity of the guide slot 8.

When inserting the connecting sleeve 3 into the inner cavity of the motor housing 1, the user needs to adjust the installation angle of the mounting seat 5 so that the guide plug plate 7 on one side thereof is aligned with the guide slot 8. When the mounting seat 5 is in contact with the fixing seat 2, the guide plug plate 7 will be inserted into the inner cavity of the guide slot 8.

[0025] It is worth noting that a replaceable nozzle body 4 is provided on the side of the connecting sleeve 3 away from the fixing seat 2, and a rotating buckle assembly is provided between the nozzle body 4 and the connecting sleeve 3.

[0026] By setting the rotating buckle assembly, the nozzle body 4 can be detachably installed on one side of the mounting base 5. Specifically, during installation, the user can move the nozzle body 4 and insert the clamping ring 12 on one side into the air avoidance groove 14 in the inner cavity of the mounting base 5. During installation, it is necessary to pay attention to aligning the clamping groove 13 with the fixed clamping base 10 and the clamping protrusion 11. When the clamping ring 12 is fully inserted into the inner cavity of the air avoidance groove 14, the user can rotate the nozzle body 4 to clamp and fix the clamping groove 13 on the surface of the fixed clamping group and the clamping protrusion 11, thereby achieving the purpose of clamping and fixing the nozzle body 4.

[0027] Furthermore, when the nozzle body 4 is rotated, the rotation angle is 25° to 40°, preferably 35°.
