Embodiment

Embodiment of the present utility model is described below in detail, the example of the embodiment is shown in the drawings, wherein from beginning Same or similar element is represented to same or similar label eventually or there is the element of same or like function.Below by ginseng The embodiment for examining accompanying drawing description is exemplary, it is intended to for explaining the utility model, and it is not intended that to the utility model Limitation.

Below with reference to the accompanying drawings it is described in detail according to synchronizer of the present utility model.

As shown in Figures 1 to 4, according to synchronizer of the present utility model, including：Rotary shaft 100, rotating disk 200.

Specifically, there are multiple annular grooves that the axially spaced-apart along rotary shaft 100 is arranged on the periphery wall of rotary shaft 100 101, and there is the first central through hole 102 axially through rotary shaft 100 along rotary shaft 100 in rotary shaft 100.

Rotating disk 200 is connected with one end of rotary shaft 100, has on the periphery wall of rotating disk 200 along the circumferential uniform of rotating disk 200 Spaced apart multiple notches 201, and there is the second central through hole axially through rotating disk 200 along rotating disk 200 on rotating disk 200 202, the second central through hole 202 and the first central through hole 102 are coaxial.

Advantageously, described synchronizer also includes mounting bracket 300, and mounting bracket 300 is located on rotating disk 200, on mounting bracket 300 With multiple mounting jaws 301, each mounting jaw 301 coordinate in corresponding each notch 201 correspondingly with multiple notches 201 It is interior.

Advantageously, each notch 201 along rotating disk 200 axially through rotating disk 200.Each notch 201 includes rectangular aperture Portion and semicircular base.The quantity of multiple notches 201 is eight, and the quantity of multiple mounting jaws 301 is eight.Multiple annular grooves 101 quantity is two.

Axial fan is typically made up of multiple blades, and theory wind is the running frequency ripple with fan blade during blower fan work Form is advanced, and is to have higher-pressure region and low-pressure area to be interspersed on the Plane of rotation of blower fan.For air valve blades, suffered wind Pressure influences to be also different, there is cyclic swing.Rotary air-valve synchronizer of relying on oneself is exactly suffered by each air valve blades Power is evenly distributed, and air valve blades can be stablized and opens.

According to synchronizer of the present utility model, designed using self-operated type mechanism, without electric and pneumatic control, completely by gas Flow control, when blower fan is opened, air-valve automatically opens up, and air-valve is also simultaneously automatic when blower fan is closed closes.

According to synchronizer of the present utility model, using rotary synchronous mechanism, resistance is small, compact-sized, gap is small, can be with Effectively overcome the shock wave effect due to being formed when fan blade rotates.With the advantages of noise is low, windage is low, efficiency high.
