Description

Pump pressure gauge

The present invention mainly discloses a pressure gauge, especially a pump pressure gauge.

Please refer to Chinese Patent No. I638982 "Pressure Gauge with Different Spacing Scales", which is a pressure gauge, which includes a base and a sensing device, the base has a surface, and when the pointer points to the low-pressure scale area The difference between the measured pressure values represented by each unit angle rotated by the pointer is smaller than the measured pressure value difference represented by the pointer rotated per unit angle when the pointer points to the high pressure scale area. The base is provided with a slideway, and the sensing device is set on the slide In the channel, the sensing device includes an elastic pressure sensor, the elastic pressure sensor includes a first elastic part and a second elastic part, the first elastic part and the second elastic part are compression springs and are connected in series. connected, the first spring constant is not equal to the second spring constant.

However, the above-mentioned pressure gauge needs to be provided with a scale plate marked with a pressure value so that the user can identify the pressure value, and a transparent upper cover must be provided to prevent dust and dirt from entering the pressure gauge, which requires a large number of components.

In view of the lack of the above-mentioned conventional structure, the present inventor has designed a pump pressure gauge, which can overcome all the shortcomings of the above-mentioned conventional structure.

The main purpose of the pump pressure gauge of the present invention is to provide a pressure gauge including a body, a pointer and an upper cover, the pointer is pivoted on the body, the upper cover is connected to the body, and the pointer is arranged on the body and the Between the upper covers, the upper cover is provided with a first marking area and a pointer viewing area, the pointer viewing area corresponds to the pointer and is adjacent to the first marking area, and the light transmittance of the pointer viewing area is greater than that of the first marking area The light transmittance of the pressure gauge can be simplified through the above design.

The pointer viewing area is in the shape of a through hole, and the pointer viewing area penetrates the upper cover and communicates with the side of the upper cover adjacent to the pointer and the side of the upper cover opposite to the pointer.

The pointer viewing area is in the shape of a circular arc, the upper cover is provided with a second marking area, the second marking area is adjacent to the pointer viewing area and is arranged on a side adjacent to the center of the arc, and the first marking area is arranged on the side of the arc center. The side of the pointer viewing area away from the center of its arc.

The first marking area is provided with a first scale, the second marking area is provided with a second scale, and the first scale and the second scale are respectively pressure values with different units.

Other objects, advantages and novelties of the present invention will become more apparent from the following detailed description and the associated drawings.

Regarding the techniques, means and effects of the present invention, a preferred embodiment is given and described in detail in conjunction with the drawings.

Referring to FIGS. 1 to 5 , it is a three-dimensional appearance view, a three-dimensional exploded view, a plane appearance view and a cross-sectional structure view of the pump pressure gauge of the present invention. The pressure gauge 10 of the present invention includes a body 20 , a pointer 30 and an upper cover 40 ; wherein: the pointer 30 is pivoted on the body 20 .

The upper cover 40 is connected to the main body 20 and covers the side of the pointer 30 opposite to the main body 20 , the pointer 30 is disposed between the main body 20 and the upper cover 40 , and the upper cover 40 is provided with a first marking area 41 and a Pointer viewing area 42, the pointer viewing area 42 corresponds to the pointer 30 and is adjacent to the first marking area 41, the light transmittance of the pointer viewing area 42 is greater than that of the first marking area 41, the pointer viewing area 42 can be translucent, transparent or hollow, and the first marking area 41 can be translucent or opaque.

The pointer viewing area 42 is in the shape of a through hole in this embodiment. The pointer viewing area 42 penetrates the upper cover 40 and communicates with the side of the upper cover 40 adjacent to the pointer 30 and the side of the upper cover 40 opposite to the pointer 30 .

The pointer viewing area 42 is in the shape of a circular arc, and the upper cover 40 is provided with a second marking area 43. The second marking area 43 is adjacent to the pointer viewing area 42 and is disposed on the side adjacent to the center of the circular arc. A marking area 41 is disposed on the side of the pointer viewing area 42 away from the center of the arc.

The first marking area 41 is provided with a first scale 411 , the second marking area 43 is provided with a second scale 431 , and the first scale 411 and the second scale 431 are pressure values with different units respectively.

The pressure gauge 10 can simplify the structure through the above-mentioned design. Compared with the traditional pressure gauge, the pressure gauge 10 has the design of directly setting the scale on the upper cover 40 , so that the pressure gauge 10 does not need to be additionally provided with a scale plate, thereby reducing the number of components of the pressure gauge 10 .

From the above, it can be concluded that the present invention has the following advantages: 1. It is a pump pressure gauge of the present invention, wherein the pressure gauge includes a body, a pointer and an upper cover, the pointer is pivoted on the body, and the upper cover is connected to the The body, the pointer is arranged between the body and the upper cover, the upper cover is provided with a first marking area and a pointer viewing area, the pointer viewing area corresponds to the pointer and is adjacent to the first marking area, the pointer viewing area The light transmittance of the pressure gauge is greater than that of the first marking area, and the pressure gauge can simplify the structure through the above design.

However, the above are only preferred embodiments of the present invention, and should not be used to limit the scope of implementation of the present invention. Therefore, any changes in numerical values or replacement of equivalent components, or equivalents made according to the scope of the patent application of the present invention Changes and modifications should still fall within the scope of the patent of the present invention.
