Description

Technical Field

[0001] This utility model relates to the technical field of pressure gauge marking devices, and in particular to a pressure gauge color warning marking making device. Background Technology

[0002] Pressure gauges are frequently used in industrial production. To prevent equipment overpressure and to allow operators to monitor equipment pressure status in real time, pressure gauges are often required to be color-coded for warning purposes, with red, yellow, and green being common colors. Currently, the common practice for color-coding pressure gauges is to directly purchase three-color labels and affix them to the gauges.

[0003] However, existing warning signs have the following drawbacks: 1. Warning signs need to be purchased and stored in advance for future use.

[0004] 2. The warning label is an adhesive backing. With prolonged use or storage, the adhesive may age and fail.

[0005] 3. Adhesive warning signs are prone to falling off in high temperature and humid environments.

[0006] 4. The pasting process relies entirely on manual application, making it difficult to accurately align the color markings with the pressure gauge scale, which can easily mislead the operator. Summary of the Invention

[0007] The technical problem to be solved by this utility model is that existing warning labels have a short service life and low manufacturing precision.

[0008] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a pressure gauge color warning mark making device, including a guide rail ring, a positioning structure fixedly connected to the middle of the guide rail ring, and a slider slidably connected to the guide rail ring. The guide rail ring is provided with a positioning groove, which is set directly opposite to the scale on the pressure gauge.

[0009] Preferably, the guide ring includes two coaxially arranged connecting rings, the positioning groove is located between the two connecting rings, one end of the slider is fixedly connected to the outer connecting ring, and the other end is slidably connected to the inner connecting ring.

[0010] Preferably, the slider is set at an angle around the axis of the guide ring.

[0011] Preferably, the bottom of the slider is provided with an arc-shaped groove, which engages with the top of the inner connecting ring. A limiting protrusion is provided at the opening of the arc-shaped groove, which is adapted to the annular groove on the outer side wall of the inner connecting ring.

[0012] Preferably, a ball bearing is embedded in the inner wall of the arc-shaped groove, and the ball bearing fits against the outer wall of the inner connecting ring.

[0013] Preferably, the guide rail ring includes two coaxially arranged connecting rings, the positioning groove is located between the two connecting rings, a permanent magnet is provided inside the slider, and two arc-shaped clamping grooves are opened at the bottom of the slider, the clamping grooves are respectively connected to the two connecting rings.

[0014] Preferably, the positioning structure includes a circular central fixing plate coaxially disposed inside the guide rail ring, and the central fixing plate has a positioning structure in the middle that aligns the central fixing plate with the central axis of the pressure gauge dial pointer. The central fixing plate and the guide rail ring are fixedly connected by reinforcing ribs.

[0015] Preferably, the positioning structure is an observation hole located at the center of the central fixed plate.

[0016] Preferably, the reinforcing ribs are connected to the bottom of the inner wall of the guide rail ring, and the reinforcing ribs are distributed at equal angles around the axis of the central fixing plate.

[0017] Preferably, a silicone suction cup is provided at the bottom of the central fixing plate.

[0018] This utility model provides a device for making color warning marks for pressure gauges, which has the following beneficial effects.

[0019] 1. By precisely aligning the positioning groove on the guide rail ring with the pressure gauge scale, combined with the positioning structure of the central fixing plate, the sliding path of the slider strictly matches the scale lines. When operators use the slider to mark warning zones with color, the markings and scales are precisely aligned, solving the problem of easy misalignment in traditional manual label pasting and effectively avoiding misleading the operator.

[0020] 2. Labels that do not rely on adhesive backing can be directly applied using a device, creating a more secure bond to the pressure gauge surface. They are less prone to detachment in harsh environments such as high temperatures and humidity, and do not suffer from adhesive aging or failure, significantly improving the durability of warning labels and reducing the need for frequent replacements.

The guide rail ring 2 is provided with a positioning groove, which is set directly opposite to the scale on the pressure gauge.

[0024] Select the corresponding size guide ring 2 according to the pressure gauge model so that the positioning groove on the inner side of the guide ring 2 can match the scale of the pressure gauge.

[0025] The pressure gauge is positioned and installed using a positioning structure aligned with its center. The guide ring 2 is then fitted to the surface of the pressure gauge. By rotating the slider 1, it rotates around the guide ring 2, positioning the two sliders 1 at opposite ends of the pressure gauge's warning zone. Warning marks are then drawn in the positioning groove located between the two pressure gauges using a marker or colored pen. Once completed, the assembly is removed, thus finishing the work.

[0026] Example 2 like Figure 1 As shown. The guide ring 2 includes two coaxially arranged connecting rings, the positioning groove is located between the two connecting rings, one end of the slider 1 is fixedly connected to the outer connecting ring, and the other end is slidably connected to the inner connecting ring.

[0027] The positioning groove is the gap between the two connecting rings, forming a ring. The two connecting rings are a split structure. The slider 1 rotates on the inner connecting ring. By rotating the slider 1, the slider 1 can be moved to the edge of the warning scale area.

[0028] like Figure 1 As shown. The slider 1 is set at an equal angle around the axis of the guide ring 2. By setting multiple sliders 1, the stability of the connection between the two connecting rings is ensured.
