Referring again to Figures 1 and 2, a second cushioning member 50b may be located in the first portion 30 of the protective cap 200. [ The second buffer member 50b may have a shape protruding from the inner surface of the first portion 30.

The second buffer member 50b may be formed as a protrusion or a linear shape like the first buffer member, and may be made of a material having elasticity, for example, a rubber material.

When the protective cover is formed as in the embodiment of the present invention, when an external impact is applied, a part of the impact is absorbed and relaxed by the projecting structure of the first portion 30, so that the impact may not be transmitted to the display panel.

Therefore, the second buffer member 50b may not be formed as in the protective cover 206 shown in Fig.

The first buffer member 50a and the second buffer member 50b may be integrally formed with the first portion 30 and the second portion 40. The first buffer member 50a and the second buffer member 50b may be formed integrally with each other, The first buffer member 50a and the second buffer member 50b may be formed on the first portion 30 and the second portion 40 in a separate process.

Hereinafter, a pressure gauge having a protective cover will be described with reference to the drawings.

FIG. 6 is a schematic exploded perspective view of a pressure gauge according to an embodiment of the present invention, and FIG. 7 is a schematic sectional view of the pressure gauge of FIG.

The pressure gauge 100 includes a coupling portion 21 such as a screw thread, a pressure transfer portion 22 and a display portion 23 so as to be coupled to the vessel and the pipeline, and a transparent window coupled to the display portion 23.

A through hole for transmitting pressure is formed inside the engaging portion 21, and the gas or fluid moves through the through hole.

The through hole (21) may be provided with a pressure transmitting portion (22) including an elastic tube which deforms in accordance with a change in pressure.

The pressure change transmitted from the pressure transmitting section 22 is visually displayed by the display section 23. The display section 23 includes a main body 23a connected to the pressure transmitting section 22, a display panel 23b accommodated in the main body 23a and an indicator pin 23c provided on the display panel 23b .

The indicating needle 23c is installed to be rotatable by the pressure transmitted from the pressure transmitting portion 22. The indicating plate 23b is provided with a pressure value Is displayed.

The transparent window may be made of a transparent material, for example, glass, in order to protect the indicator needle 23c and to prevent the indicator needle 23c from being exposed and exposed to the external environment.

1 and 2, the protective cover 200 may be coupled to cover and protect the display unit 23, and the first portion 30 may be coupled to the display panel 23b, And the second portion 40 is formed along the rim of the first portion 30 and surrounds the outer surface of the main body 23a.

The first portion 30 protrudes from one surface of the display panel 23b and has a concave space in the inside with a convex structure. When the first portion 30 is formed in a convex shape, the shock is naturally absorbed when an external impact is applied, or the shock can be easily dispersed to be buffered.

And the body of the pressure gauge can be inserted and coupled to the extension space S2 formed by the second portion 30. [

Thus, the first cushioning member 50a formed on the second portion 40 is in contact with the outer surface of the main body 23a.

The first cushioning member 50a is located between the outer surface of the main body 23a and the second portion 40 of the protective lid 200 to eliminate the gap between the protective lid 200 and the main body 23a, (200) can be brought into close contact with the main body (23a). Accordingly, the first cushioning member 50a may be formed of a resilient rubber material, and may be integrally formed with the second portion 40, or may be formed separately on the second portion 40. [

At this time, since the protective cap 200 and the main body 23a are pressed and engaged by the first cushioning member 50a, the protective cap 200 can be fixed to the main body 23a without a separate coupling part.

The second buffer member 50b formed on the first portion 30 of the protective cover 200 can protrude toward the display panel 23b. At this time, the second buffer member 50b may be spaced apart from the display panel 23b.

When the pressure gauge is formed with the protective cover having the buffer member as in the embodiment of the present invention, when the external impact is applied, the impact is partially absorbed and relaxed by the projecting structure of the first portion 30, . Therefore, it is possible to prevent the transparent window of the pressure gauge from being damaged.

On the other hand, the protective cover 200 can be installed on the pressure gauge only when necessary. For example, it can be installed on a pressure gauge only during paint work and maintenance. Thus, in order to easily recognize that the pressure gauge is located during operation, the protective cover 200 may have a noticeable color such as a fluorescent color.

At this time, it is possible to prevent the pressure gauge from being impacted by inserting a cautionary note on the protective cap 200, such as glass caution and shock caution.

As described above, when the protective cover 200 and the main body 23a are coupled with each other through the cushioning member as in the present invention, the impact is relieved or absorbed by the cushioning member 50 even when an external impact is applied, It can be prevented from being damaged.

In addition, when the protective cover 200 is contaminated and the identification of the display panel 23b is difficult, the protective lid 200 is coupled to the main body by pressurizing through the cushioning member 50 made of elastic material, can do.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, Of course.
