[embodiment]
Extremely shown in Figure 4 like Fig. 1, the rotary regulating structure of a kind of electric fan of the present invention, it comprises fuselage 1, connecting base 2, ball 3, spring sheet 4 and running shaft 5, said connecting base 2 rotates with respect to said fuselage 1 around said running shaft 5.Said ball 3 is fixed on the said fuselage 1; Said spring sheet 4 is fixed on the said connecting base 2, and said ball 3 offsets with the diverse location of said spring sheet 4, and to the said spring sheet 4 of precompressed; Said connecting base 2 rotations drive said ball 3 rotations; Because the elastic force of spring sheet 4 makes the ball 3 can elasticity springing on said spring sheet 4, thereby reach the flexible adjustment of multi-angle, and wear-resistant degree height.
In the present invention; Said spring sheet 4 is the U type, is processed by the elastic material punching press, and its two ends are mounting end 41 (as shown in Figure 3); Said mounting end 41 is inside or bandy hook-shaped; In order to save the space, do not increase the volume of said connecting base, the preferred said mounting end 41 of present embodiment is aduncate hook-shaped.The lower end of said connecting base 2 is provided with the mounting groove 21 that is used to install said spring sheet 4, and the two ends of said mounting groove 21 are provided with the stria 22 that cooperates with the mounting end 41 of said spring sheet 4.Preferably, the internal diameter of said stria 22 is slightly larger than the external diameter of said mounting end 41.Preferably, said spring sheet 4 is provided with at least two positioning holes 42, makes said ball 3 can place different positioning hole 42 so that this electric fan can be fixed in different angles blows, and present embodiment preferably is provided with three positioning holes.
For the elastic force that makes said spring sheet 4 has certain Free up Memory; Make the rolling that said ball 3 can multi-angle; The level of said mounting groove 21, Vertical direction leave horizontal space 23, vertical space 24 so that said spring sheet 4 can be in the horizontal direction, the Vertical direction springing, behind the said spring sheet 4 of ball 3 compressings; Said spring sheet 4 can be in the horizontal direction, the free springing of Vertical direction, realizes the adjusting of said connecting base 2 multi-angles.
