Description

Inflator with the double tables of high-low pressure

Technical field

The present invention relates to inflator, more particularly to a kind of inflator with the double tables of high-low pressure.

Background technology

It is a kind of mini formula inflators with the double tables of high-low pressure as shown in US5779457 cases, its Surface is in strip, and scale is fine and closely woven, and the position of piston is watched by the window of elongated shape by the displacement of piston Put and interpretation pressure value, this can be an experience for pain for the user having defective vision, then The double tables of person can often cause user to mix up side by side, not know which table seen.

The content of the invention

It is a primary object of the present invention to provide a kind of inflator with the double tables of high-low pressure, it conveniently makes User watches interpretation.

To reach purpose disclosed above, according to provided by the present invention a kind of with the double tables of high-low pressure Inflator, its feature is there is two circular pointer pressures, is in juxtaposition in 180 degree It is oppositely arranged, two pressure gauges and can together 360 degree upset, with convenient use person watch interpretation.

Embodiment

Now coordinate brief description of the drawings as follows for two example two：

It is first embodiment of the invention as shown in Fig. 1 to 5, is a kind of mini (mini of formula inflator 10 Pump), it includes：

One stack shell 11.

One piston 12, located at the stack shell 11.

One inflating rod 13, one end is located at the piston 12, and the other end is passed by one end of the stack shell 11.

One handle 14, located at the other end of the inflating rod 13.

One pressure watch shell 15, the other end of the stack shell 11 is located at one end, two circles are which is provided with The pointer pressure 2030 of shape, one is high pressure gauge 20, and another is low-pressure meter 30, in 180 degree It is oppositely arranged, surfaces facing outward, two pressure gauges 2030 are respectively with air flue 2131 and the stack shell 11 Connection.

One tuyere casing 16, is hubbed on the other end of the pressure watch shell 15, can be with 360 degree certainly By rotating, it is interior provided with tuyere head component 40, and is connected with air flue 41 with the stack shell 11.

Before use, it is high pressure gauge to be used or low-pressure meter that can first select, the surface being selected direction is allowed to make User, then wind fairing head 40 is connected valve cock, using upper very convenient, and due to being to use Circular pointer pressure, thus display be perfectly clear, interpretation be very easy to.

It is second embodiment of the invention as shown in Fig. 6 to 8, is a kind of (floor of console model inflator 50 Pump), it includes：

One stack shell 51.

One piston 52, located at the stack shell 51.

One inflating rod 53, one end is located at the piston 52, and the other end is passed by one end of the stack shell 51.

One handle 54, located at the other end of the inflating rod 53.

One gas guiding component 55, located at the stack shell 51, with an exposed junction 551.

One flexible pipe 56, one end is fixedly arranged on the exposed junction 551 of the gas guiding component 55.

One wind fairing head 57, is fixedly arranged on the other end of the flexible pipe 56.

One air entraining passage 58, is connected with the gas guiding component 55.

One pressure watch shell 60, which is provided with two circular pointer pressures 70,80, one For high pressure gauge 70, another is low-pressure meter 80, surfaces facing outward oppositely arranged in 180 degree, a projection 61 are located at the side of pressure watch shell 60, and the projection 61 is central by being provided with an air flue 62 inside outside, Two pointer pressures 70,80 and connected respectively with the air flue 62, the pressure watch shell 60 Be with its projection 61 is hubbed on the air entraining passage 58 and can be 360 degree freely rotate.

Thereby, the rotatable pressure watch shell 60 of user and select use high pressure gauge 70 or low pressure Table 80, using upper very convenient.
