Detailed Description

In order to make the technical problems, technical solutions and advantageous effects to be solved by the present invention more clearly apparent, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the utility model.

Referring to fig. 1, fig. 2 and fig. 3, the rotating device of the present invention is disposed between an air outlet grille 1 and a turntable base 2, and the rotating device includes at least three sets of bearings 3 and bearing positioning shafts 4.

Each bearing positioning shaft 4 is respectively arranged on the air outlet grille 1 positioned at the lower part. The bearing 3 is mounted on the bearing positioning shaft 4 with interference. The slide way 5 is arranged on the bottom surface of the turntable base 2 positioned at the upper part, and the outer ring 31 of each bearing 3 rotates along the same slide way 5, as shown in fig. 5. The structure can ensure the rotation concentricity of the air outlet grille 1 and the turntable base 2 and reduce the eccentric amount.

Referring to fig. 2, fig. 3 and fig. 4, a through hole 11 of the bearing positioning shaft 4 is installed on the air outlet grille 1, and the bearing positioning shaft 4 penetrates through the through hole 11. The bearing positioning shaft 4 and the through hole 11 are in interference fit. The bearing positioning shaft 4 is provided with a shaft shoulder 6, and the shaft shoulder 6 is abutted against the bottom surface of the air outlet grille 1.

A fan support 7 is further arranged at the lower part of the air outlet grille 1, and a support table 8 is arranged on the fan support 7, as shown in fig. 6. The support table 8 is supported on the bottom surface of the bearing positioning shaft 4 to prevent the bearing positioning shaft 4 from being loosened.

Set up bulge loop 9 on air outlet grid 1, bulge loop 9 sets up the top surface at air outlet grid 1, and is located the top of every through-hole 11, and the inner circle 32 of bearing 3 supports and leans on bulge loop 9.
