Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0040] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0044] See Figures 1 to 5 An embodiment of this utility model provides an external pressure gauge indicator structure, which includes a connector 100 and at least two indicator holders 200. The connector 100 is constructed as a ring structure and is arranged around the outer circumference of the pressure gauge and fixedly connected to the pressure gauge. The indicator holders 200 are spaced apart from each other along the circumference of the connector 100. The indicator holders 200 are movable relative to the connector 100 to adjust their position on the connector 100. At least one indicator holder 200 points to a preset lower pressure limit value on the pressure gauge, and at least one indicator holder 200 points to a preset upper pressure limit value on the pressure gauge.

[0045] This technical solution provides an external pressure gauge indicating structure, which includes a connector 100 and at least two indicator holders 200. The connector 100 is used to fix the pressure gauge. Specifically, by constructing the connector 100 as a ring structure and surrounding the outer circumference of the pressure gauge, the connection between the external pressure gauge indicating structure and the pressure gauge is achieved by fixing the connector 100 to the pressure gauge. By providing at least two indicator holders 200, and by configuring the indicator holders 200 to be movable relative to the connector 100, the position of the indicator holders 200 on the connector 100 can be adjusted, allowing the indicator holders 200 to point to different pressure values ​​on the pressure gauge. Furthermore, by configuring at least one indicator holder 200 to point to a preset lower pressure limit on the pressure gauge and at least one indicator holder 200 to point to a preset upper pressure limit on the pressure gauge, the external pressure gauge indicating structure can provide the required high and low pressure limit warnings for the pressure gauge. With the above settings, not only can high and low pressure limit warnings be easily implemented, but it is also easy to disassemble and assemble, and no residue is left on the surface of the pressure gauge after disassembly and assembly. Furthermore, it can be flexibly adjusted according to actual needs and is reusable. In other embodiments, this application can also be used for indicating dials such as thermometers.

[0046] In one embodiment, the indicator 200 includes a snap-fit ​​portion 210 and an indicator portion 220 connected to each other. The snap-fit ​​portion 210 is configured with a snap-fit ​​groove, and at least a portion of the connector 100 is disposed in the snap-fit ​​groove. The indicator portion 220 extends in a direction away from the snap-fit ​​portion 210 and points to a preset lower limit pressure value or an upper limit pressure value.

[0047] In this embodiment, the snap-fit ​​part 210 is used to connect the indicator bracket 200 and the connector 100, and the indicator part 220 is used to point to the preset warning pressure value on the pressure gauge. Specifically, the warning pressure value includes a lower limit pressure value and an upper limit pressure value. For example, in a specific application scenario, the pressure value of the pipeline must not be lower than 0.4 MPa and must not be higher than 0.8 MPa. Then, the preset lower limit pressure value is the 0.4 MPa position on the pressure gauge, and the preset upper limit pressure value is the 0.8 MPa position on the pressure gauge. That is to say, in this application scenario, at least one indicator bracket 200 in the external indicator structure of the pressure gauge points to the 0.4 MPa position on the pressure gauge, and at least one indicator bracket 200 points to the 0.8 MPa position on the pressure gauge.

[0048] It is understood that in this embodiment, the number of indicator holders 200 can be two, three, or even more. As a preferred embodiment, the number of indicator holders 200 is three, with one indicator holder 200 pointing to a preset lower pressure limit, one pointing to a preset upper pressure limit, and one pointing to a preset recommended pressure value. For example, in the above application scenario, the recommended pressure value could be 0.6 MPa.

[0049] In one embodiment, the snap-fit ​​portion 210 is configured as a plate-like structure, and the snap-fit ​​portion 210 includes an extension portion 211 and a bending portion 212. One end of the extension portion 211 is connected to the indicator portion 220, and the other end extends in a direction away from the indicator portion 220. One end of the bending portion 212 is connected to the extension portion 211, and the other end is bent and extends in a direction close to the indicator portion 220. The extension portion 211 and the bending portion 212 form a snap-fit ​​groove.

[0050] The extension section 211 is used to connect the indicator section 220 and the bending section 212. By forming a snap-fit ​​groove between the extension section 211 and the bending section 212, the indicator 200 can be snapped onto the connector 100. By setting the snap-fit ​​part 210 as a plate-like structure, the snap-fit ​​part 210 can make surface contact with the connector 100, thereby improving the reliability of the connection between the snap-fit ​​part 210 and the connector 100.

[0051] In one embodiment, the connector 100 includes a clamp 110 and a gasket 120. The inner diameter of the clamp 110 is adjustable. The gasket 120 is disposed on the inner circumferential surface of the clamp 110 and contacts the pressure gauge. Using the clamp 110 to fix the pressure gauge provides efficient and convenient installation with strong clamping force. By providing the gasket 120 on the inner circumferential surface of the clamp 110, the surfaces of the pressure gauge and the clamp 110 are isolated, thereby preventing the outer circumferential surface of the pressure gauge from being scratched by the clamp 110. Specifically, the gasket 120 is made of a flexible, deformable material, such as a rubber pad.

[0052] In one embodiment, the external pressure gauge indicating structure further includes a fixing member detachably connected to the connector 100. The fixing member has a clamping opening with an adjustable size, and is used to clamp the pressure gauge at its two axial end faces. Further, there are two fixing members, symmetrically arranged with the center of the connector 100 as the symmetrical point. Even further, the fixing member is a dovetail clip 400.

[0053] By detachably connecting the fixing member to the connector 100, after the pressure gauge is fixed by the connector 100, the fixing member clamps the two end faces of the pressure gauge, thereby secondary fixing the pressure gauge to prevent it from sliding out along the axial direction of the clamp 110, thus improving the reliability of the connection between the pressure gauge and the connector 100. The number of fixing members is not limited; it can be one, two, three, or even more. In this embodiment, there are two fixing members, symmetrically arranged on both sides of the center of the pressure gauge, making the radial force on the pressure gauge more stable and reliable. Specifically, in this embodiment, the fixing member is a dovetail clip 400, which effectively reduces the phenomenon of the pressure gauge falling off due to the back-and-forth sliding of the clamp 110. Moreover, the dovetail clip 400 is convenient and reliable to install, easy to disassemble and adjust, and inexpensive.

[0054] In one embodiment, the external pressure gauge indicator structure also includes a tag 300, which is connected to the connector 100 and is used to identify preset information. By connecting the tag 300 to the connector 100, relevant information can be marked on the tag 300 for easy viewing by the user. Specifically, the relevant information includes instrument tag number information, inspection mark information, etc.

[0055] In one embodiment, the tag 300 includes a chain 310 and an identification plate 320. One end of the chain 310 is connected to the connector 100; the identification plate 320 is connected to the other end of the chain 310, and paper can be pasted or text information can be etched on the identification plate 320. Furthermore, the identification plate 320 has at least one connecting hole 321, through which the chain 310 passes.

[0056] In this embodiment, the chain 310 is used to connect the label plate 320, which is used to identify relevant information. Specifically, the label plate 320 is designed to accept paper, allowing relevant information to be printed on paper and then displayed by attaching the paper to the label. Alternatively, the text information can be directly etched onto the label plate 320 to display the relevant information. A connection hole 321 is provided on the label plate 320, through which the chain 310 passes, thereby connecting the label plate 320 to the connector 100.

[0057] In use, the external pressure gauge indicating structure provided in this embodiment of the invention involves installing a corresponding number of adjustable indicator frames 200 on the clamp 110 as needed. The clamp 110, with the indicator frame 200 and the pad 120, is fitted onto the outer circumference of the pressure gauge and secured by tightening the clamp 110. After the clamp 110 is fixed, the indicator frame 200 is moved to the desired position by sliding the indicator frame 200, and then the clamp 110 is tightened again to secure the indicator frame 200, thus completing the installation of the device and achieving the indicating effect through the indicator frame 200.

[0058] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0059] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
