When inflated, the compressed gas pumped by the tire pump (not shown) will sequentially pass through the hose 210, the second hole 1051, the passage 103, the first hole 101 to the bicycle tire valve in the valve stem hole 132. The valve stem 310, as indicated by the arrow, causes gas to be driven into the tire. In this state, since the air pressure in the passage 103 is insufficient to push the plunger 1521 of the air lock 153, the air in the passage 103 does not enter the whistle member. The vent 1512 of the 151, the whistle device 150 does not emit sound.

However, when the tire is filled with gas, as shown in FIG. 4B, since the gas cannot enter the tire through the valve stem 310, the overflowed compressed air will push the plunger 1521 of the air plug 152 in the passage 103. To move, the whistle spring 153 of the original supporting air plug 152 is compressed and deformed, and the gas can be discharged from the sound hole 1511 through the spur hole 1054, the air hole 1512 and the gap beside the sound block 155, wherein the sound block 155 is set at the whistle. In the sound member 151, when the gas is discharged through the sound hole 1511, the gas can be squeezed and vibrated to emit a sound, and the user can know whether the tire is full of gas by the sound of the whistle 1511 to stop the inflation. The action prevents the explosion of the tire and the like.

Wherein, when the hose 210 stops conveying the compressed gas, the pressure of the gas in the passage 103 is lowered, and the whistle spring 153 compressed by the air pressure is reset, so that the plunger 1521 of the air plug 152 plugs the plunger hole 10541, the whistle The sound member 150 will not make a sound. It is worth mentioning that in order to prevent high pressure air from leaking through the gap between the plunger hole 10541 and the plunger 1521 in the normal inflation state, the gasket 154 provided at the periphery of the plunger 1521 provides a further function of preventing leakage.

Figure 5 is a schematic view showing the use of a bicycle tire pump chuck with an inflation indicator sound according to a preferred embodiment of the present invention. As shown in Figure 5, the bicycle tire pump (not shown) of the present invention has an inflation indicator sound. The volume of the tire pump chuck is reduced by pivoting the pivot clamp 110 toward the main body 100 to facilitate the clamping of the valve stem 310 of the bicycle tire valve into the rim, thereby overcoming the volume of the conventionally pulled up If it is too large and can not be placed in the rim with the rim of the bicycle tire, it has the advantages of small size, no space and easy adjustment; and the whistle 150 connected to the passage 103 is used when the tire pressure is too high. When the indicator sound is given, the user can know whether the tire is full of gas by the sound of the whistle 150, so as to stop the inflation action and prevent the tire from exploding. And when it is necessary to receive different types of valve stems 310, the two valve stem holes 132 can be exchanged by pivoting the end caps 130 to facilitate the user to inflate, achieving the object of the present invention.

In summary, the bicycle tire pump chuck with the inflatable indicator sound of the present invention utilizes a pivotable end cover and simultaneously has different kinds of valve stem holes for the user to inflate, wherein the whistle can be used. When the air pressure in the tire tire is too high, an indicator sound is emitted, so that the user can know whether the tire is full of gas by using the whistle to stop the inflation action and prevent the tire from exploding, etc., by placing the pivot pin The main body is pressed down to overcome the conventional situation that the volume is too large to interfere with the rim of the bicycle tire and can not be placed in the rim, and has the advantages of small volume, no space occupation and easy adjustment. The object of the invention.

It can be seen from the above embodiments that the bicycle tire pump chuck with the inflation indicator sound provided by the present invention has industrial use value, but the above description is only for the preferred embodiment of the present invention, and the skill is fine.
