[0017] In the figure: 1 outer cover, 2 rotating disk, 3 axial flow blades, 4 rotating shaft, 51 spring mounting seat, 52 booster spring, 53 sliding ring, 54 fixing ring, 55 teeth. DETAILED DESCRIPTION
[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0019] Reference Figure 1-2 A wind supply device includes an outer cover body 1, a rotatable rotating disk 2 is installed inside the outer cover body 1, a plurality of axial flow blades 3 are arranged on the rotating disk 2, and the plurality of axial flow blades 3 are rotatably installed on the outer peripheral surface of the rotating disk 2 through a rotating shaft 4.
[0020] A locking assembly is provided on each of the plurality of rotating shafts 4, and the locking assembly includes a spring mounting seat 51, a booster spring 52, a sliding ring 53, a fixing ring 54 and a plurality of teeth 55. The spring mounting seat 51 is fixed on the outer peripheral surface of the rotating disk 2, the sliding ring 53 is slidingly sleeved on the rotating shaft 4, and the inner ring of the sliding ring 53 fits with the surface of the rotating shaft 4. One end of the booster spring 52 is connected to the spring mounting seat 51, and the other end is connected to the sliding ring 53. The fixing ring 54 is fixed to one end of the axial flow blade 3, and the inner ring of the fixing ring 54 fits with the surface of the rotating shaft 4. 4 is arranged opposite to the sliding ring 53, a plurality of teeth 55 are respectively arranged on the sliding ring 53 and the fixing ring 54, the plurality of teeth 55 on the sliding ring 53 are distributed in a circumferential array, and the plurality of teeth 55 on the fixing ring 54 are distributed in a circumferential array. The staff can adjust the angle of the axial flow blade 3 through the locking assembly. Specifically, the staff first pulls the sliding ring 53 to separate the sliding ring 53 and the fixing ring 54 from each other. Without the restriction of the plurality of teeth 55, the fixing ring 54 can rotate freely. Then the staff rotates the axial flow blade 3 and adjusts the angle of the axial flow blade 3.
[0021] The specific working principle of the utility model is as follows:
[0022] When the rotating disk 2 in the outer cover body 1 rotates, it can drive the plurality of axial flow blades 3 to rotate. The plurality of axial flow blades 3 can supply air or exhaust air when rotating, which is determined by the angles of the plurality of axial flow blades 3. The staff can adjust the angles of the axial flow blades 3 through the locking assembly. Specifically, the staff first pulls the sliding ring 53 to separate the sliding ring 53 and the fixing ring 54 from each other. Without the restriction of the plurality of teeth 55, the fixing ring 54 can rotate freely. Then the staff rotates the axial flow blades 3 and adjusts the angle of the axial flow blades 3. After the adjustment, the staff releases the sliding ring 53. Under the elastic force of the booster spring 52, the sliding ring 53 moves toward the fixing ring 54 until the plurality of teeth 55 on the sliding ring 53 are engaged with the plurality of teeth 55 on the fixing ring 54. Under the limiting action of the sliding ring 53 and the plurality of teeth 55 thereon, the fixing ring 54 and the axial flow blades 3 cannot rotate freely. This design is convenient for the staff to adjust and fix the angles of the axial flow blades 3. The adjustability of the axial flow blades 3 enables the device to realize the functions of supplying and sucking air.
