Problems solved by technology

Now in the production process, the screw is driven into the position roughly perpendicular to the D-shaped plane by the eyes of the production personnel. There are no fool-proof and error-proof measures, and the position of the screw is prone to deviation. If the screw is not vertical Hitting on a D-shaped plane, the cross-flow fan blades are prone to loosening, and the air conditioner will make abnormal noises during operation, resulting in after-sales quality failures

[0045] Please refer to figure 1 , the embodiment of the present invention provides an auxiliary fixing tool 1 for fixing the relative positions of the D-shaped motor shaft 2 and the cross-flow fan blade 3 . Its structure is simple, it can fix the relative position of the D-shaped motor shaft 2 and the cross-flow fan blade 3, and it is convenient for the screw 4 to drive in. It has the function of foolproof and error proof, and is practical and efficient. In this embodiment, after the relative position of the D-shaped motor shaft 2 and the cross-flow fan 3 is fixed by the auxiliary fixing tool 1, the screw 4 is used to pass through the gap 9 and the inner hole of the cross-flow fan 3, and fastened to the D-shaped motor shaft 2 on the flat surface 10 to ensure that the screw 4 is perpendicular to the flat surface 10 and avoid loosening of the cross-flow fan blade 3 .

[0046] Please refer to figure 2 and image 3, the auxiliary fixing tool 1 includes a first fixing part 5 an...

[0056] Please refer to Figure 4 , Figure 5 and Figure 6 , the embodiment of the present invention provides an air outlet device 25 for blowing out airflow to the outside. The air outlet device 25 includes a driving motor 26 , cross-flow fan blades 3 and auxiliary fixing tool 1 . The drive motor 26 is provided with a D-shaped motor shaft 2, and the cross-flow fan blade 3 is provided with a notch 9. The notch 9 can be connected to the D-shaped motor shaft when the bayonet 7 is engaged with the D-shaped motor shaft 2 and the hook 8 is engaged with the notch 9. 2 corresponding to the flat surface 10, so that the screw 4 stretches into the gap 9, and vertically drives into the flat surface 10. Among them, the basic structure, principle and technical effect of the auxiliary fixing tool 1 are the same as those of the first embodiment. For the sake of brief description, for the parts not mentioned in this embodiment, reference may be made to the corresponding content in the firs...

Abstract

The invention provides an auxiliary fixing tool, an air outlet device and an air conditioner, and relates to the technical field of air conditioners. The auxiliary fixing tool comprises a first fixingpiece and a second fixing piece, wherein the first fixing piece is slidably connected with the second fixing piece; the first fixing piece is provided with a bayonet; the shape of the bayonet is matched with that of a D-shaped motor shaft; the second fixing piece is provided with a hook; the hook is in clamped connection with a notch of a cross-flow fan; and the second fixing piece can slide relative to the first fixing piece when the bayonet is in clamped connection with the D-shaped motor shaft, so that the hook is in clamped connection with the notch. Compared with the prior art, the auxiliary fixing tool has the advantages that owing to the first fixing piece provided with the bayonet and the second fixing piece provided with the hook, the first fixing piece and the second fixing piece act simultaneously, the D-shaped motor shaft and the cross-flow fan can be fixed relatively, screwing-in of screws is facilitated, and the auxiliary fixing tool has functions of fool proofing and mistake proofing, and is practical and effective.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to an auxiliary fixing tool, an air outlet device and an air conditioner. Background technique [0002] At present, in order to ensure the dynamic balance of the cross-flow fan blade in the air conditioner and reduce the difficulty of production and processing, the inner hole of the cross-flow fan blade matched with the motor shaft is processed into a circle, and in order to transmit the motor torque, the motor shaft must be designed as a D shape. During production, the screw passes through the inner hole of the cross-flow fan blade and is vertically fastened on the D-shaped plane of the motor shaft to realize torque transmission. Now in the production process, the screw is driven into the position roughly perpendicular to the D-shaped plane by the eyes of the production personnel. There are no fool-proof and error-proof measures, and the position of the screw is prone to d...
