Abstract
The utility model provides a ball inflation pressure-measuring device, which comprises the following components: a gun body which is of a gun shape, a trigger which is used as an inflation switch, an air discharging valve, a pointer type air gauge which is provided at the upper end of a gun barrel, an inflation needle which is provided at one end of an inflation pipe, etc. The gun body is internally provided with a main air passage and a branch air passage. The main air passage comprises the following components: an air inlet passage in a gun handle, an inflation switch air passage which is used for mounting a movable valve, and an inflation passage which is provided in the gun barrel. The branch air passage is provided at the upper part of the gun body and is communicated with the main air passage. An instrument is hermetically equipped at the top end of the branch air passage. In inflation, the trigger is pulled. The trigger pushes a tappet valve for moving rightwards. The compressed air enters the ball through the main air passage in the gun body. After the trigger is loosened, the tappet valve moves leftwards under the function of a reset spring. The main air passage is blocked by the tappet valve for stopping inflation. A pointer on the air gauge corresponds with air pressure of the ball. If the pressure of the ball exceeds a standard value, the air discharging valve can be pressed for discharging out excessive air until the pressure of the ball accords with the standard.
