Embodiment Construction

[0032] Regarding the technology, means and effects used in the present invention, a preferred embodiment is given and described in detail below with drawings, which are for illustration purposes only, and are not limited by this structure in the patent application.

[0033] refer to figure 1 , is the three-dimensional appearance view of the pressure gauge of the present invention on the pump of the handle. The air pump of the present invention is a traditional vertical air pump. The pressure gauge of this embodiment includes an air pump 10 , a handle 20 and a hose 30 in the pump of the handle.

[0034] refer to figure 2 , is a schematic cross-sectional view of the pressure gauge of the present invention on the pump of the handle. The air cylinder 10 includes a base 11 , an outer cylinder 12 , a connecting rod 13 and an air tube 14 . The handle 20 is connected to the connecting rod 13 , and the hose 30 is connected to the base 11 .

[0035] The two ends of the base 11 ar...

Abstract

The invention provides a bicycle pump provided with pressure gage on handle, comprising an inflator, a handle and a hose; wherein the inflator comprises a base, an outer barrel, a connecting rod and an air tube, the interior of the base is provided with an air channel, the outer barrel is internally provided with a valve body, the valve body is provided with a through hole and a containing part, the through hole and the containing part are respectively communicated with the air channel, the containing part is internally provided with an anti-kickback device, so as to control gas to enter the air channel or not, a first end of the connected rod is inserted into the outer barrel and is provided with a piston, the air tube is fixed on the valve body of the outer barrel and penetrates the piston of the connecting rod and the interior of the connecting rod; the handle is arranged and connected at a second end of the connecting rod, the handle is provided with a pressure gage, the pressure gage can detect the pressure value of gas in the connecting rod; and a first end of the hose is arranged on the base, and a second end of the hose is connected with an object to be inflated.

Description

technical field [0001] The invention mainly discloses an air pump with a pressure gauge on the handle, especially an air pump that can reset the pressure gauge to zero without manual deflation. Background technique [0002] The pressure gauge installed on the handle has the advantage of being easy to read the pressure value, but the traditional pressure gauge installed on the handle needs to be equipped with an exhaust valve at the handle, and the operator needs to manually release the air after filling to further reset the value of the pressure gauge to zero . [0003] refer to Figure 8 , which is a schematic diagram of a pressure indicator of an existing bicycle pump, which is mainly composed of a watch case 91, an instrument panel 92, a pointer 93, a connecting rod 94, a shaft tube 95, a spring 96, an exhaust valve 97 and a handle body 98, etc. Composition, wherein the watch case 91 is a transparent body, covering the top surface of the handle body 98 outside the instru...
