Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belongs to the scope of the utility model protection.
Embodiment 1
Refer in Fig. 1~3, the utility model embodiment, a kind of Frequency Adjustable whistle based on rotary wind porose disc, including gas
Mouth 1, rotary wind porose disc 2, axle sleeve 3, rotating shaft 4 and sounding box 5, one end of the sounding box 5 are provided with air admission hole, while sounding box 5
Surface open up venthole, the gas that is entered by air admission hole impact venthole simultaneously produces vibrations, and then sounding, and sounding box 5 is set
The one end for having air admission hole passes through the outlet side of connection buckle clamping valve 1, venthole and the one end of sounding box 5 of the outlet side of valve 1
Air inlet bore dia it is identical and be coaxially disposed, rotary wind porose disc 2, rotary wind porose disc 2 are set between the valve 1 and sounding box 5
End face of the both ends of the surface respectively with valve 1 and sounding box 5 combine closely, it is to avoid leak out, by rotating the regulation punching of rotary wind porose disc 2
The air-flow size of the venthole of sound box 5 is hit, and then sends different frequency volume birdie.
The centre bore of the rotary wind porose disc 2 is rotatably connected on the axle jack that the one end of sounding box 5 correspondence is opened up by rotating shaft 4
It is interior, in order to the rotation of rotary wind porose disc 2, axle sleeve 3 is set, axle sleeve 3 can be between rotating shaft 4 and the centre bore of rotary wind porose disc 2
For damped rubber ring, in order to which rotary wind porose disc 2 is positioned, the axle jack is located at the surface of air admission hole, and rotary wind porose disc 2
