Problems solved by technology
[0003] Among them, the current existing bicycle pump chuck does not have an inflation reminder function, so when inflating, it is easy to cause underinflation or overinflation to make the gas pressure in the tire too high. However, when the tire is overinflated, it is easy to cause the tire Excessive tensioning of the carcass causes fatigue fracture, which makes the carcass easy to break and damage, and in severe cases, a tire blowout may occur
[0004] In addition, when the existing bicycle air pump chuck is connected and inflated, the chuck is sealed with the air valve by pulling up the wrench. However, after the wrench is pulled up, the thickness of the bicycle air pump chuck will increase. , when it is necessary to inflate a bicycle tire with a smaller rim, the wrench of the existing bicycle air pump chuck will interfere with the rim, so that the pump chuck cannot enter the rim and hold the valve stem for inflation. There is a need to improve the above deficiencies

Embodiment Construction
[0075] The embodiments of the present invention will be described in more detail below in conjunction with the drawings and component symbols, so that those who are familiar with the technical field of the present invention can implement the present invention accordingly after studying this specification.
[0076] Figure 1A , 1B Respectively, a perspective view and an exploded view of a bicycle tire pump chuck with an inflation indicator sound showing a preferred embodiment of the present invention. Such as Figure 1A , 1B As shown, the bicycle tire pump clamp with inflation indication sound includes: a main body 100 , a pivot clip 110 , a spring 120 , an end cap 130 , a seal 140 and a whistle device 150 .
[0077] Please refer to Figure 1C As shown, the main body 100 has a first hole 101, a connecting portion 102, a channel 103, a spring receiving groove 1052 and a whistle hole 1054; the first hole 101 is located on a top surface of the front section of the main body 100 ...

The invention provides a bicycle tire pump chuck with an air charging indication voice. The bicycle tire pump chuck comprises a body, an end cover and a pivot clamp which are arranged on the body anda whistle device arranged on the body; the end cover can rotate relative to the body and is selectively arranged inside a valve rod hole in the end cover to be cooperatively connected with to a valverod of a tire, the valve rod is fixed to the end cover through cooperation of the pivot clamp, during air charging, the whistle device bears normal air pressure and will not make the voice, and when air charging exceeds preset pressure, pressure acts on the whistle device to make the voice for warning so as to prevent that since the tire is excessively charged with air, tire explosion occurs.
Description
technical field [0001] The invention relates to a pump chuck for bicycle tires, in particular to a bicycle tire pump chuck with different types of valve stem holes that can be rotated and selected, and an indication sound when the air pressure in the tire is too high. Background technique [0002] The pump chuck is a kind of clamp used to couple the bicycle tire and an air source. When inflating, the valve stem hole of the pump chuck is generally air-tightly clamped with the valve stem of the tire valve. The pump chuck The other end is connected to the hose of the air pump or hand air pump, and in order to properly inflate the tire, the pump chuck must be sealed with the valve stem to avoid or limit air leakage from the connection between the pump chuck and the valve stem come out. [0003] Among them, the current existing bicycle pump chuck does not have an inflation reminder function, so when inflating, it is easy to cause underinflation or overinflation to cause the gas ...
