Description

Technical Field

[0001] This utility model relates to the field of pressure gauges, specifically a pressure gauge with a protective structure. Background Technology

[0002] A pressure gauge with a protective structure is a special type of pressure gauge designed to protect its core components, such as the movement and Bourdon tube, from damage in harsh environments or potentially hazardous conditions, thereby ensuring measurement accuracy and extending its service life.

[0003] However, most pressure gauges with protective structures are currently quite troublesome to install and disassemble, requiring the loosening of multiple bolts. This is because the protective casing is usually secured with multiple bolts to ensure a tight and stable seal between the casing and the gauge body, preventing the intrusion of external dust, moisture, corrosive media, etc., thus ensuring the normal operation and measurement accuracy of the precision components inside the pressure gauge. However, this design also leads to low installation and disassembly efficiency. When the pressure gauge needs to be regularly maintained, calibrated, or replaced, operators need to spend a lot of time loosening and tightening the bolts one by one, thus increasing the difficulty of maintenance and disassembly. Summary of the Invention

[0004] Therefore, the purpose of this utility model is to provide a pressure gauge with a protective structure to solve the technical problem that most pressure gauges with protective structures currently use multiple bolts to fasten the outer shell, which leads to low efficiency during installation and disassembly. Operators need to spend a lot of time loosening and tightening the bolts one by one, thus increasing the difficulty of maintenance and disassembly.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a pressure gauge with a protective structure, comprising a pressure gauge body, wherein a fixed base and a protective buckle cover are respectively provided at the front and rear ends of the pressure gauge body, the fixed base includes a rear cover, the rear cover is attached to the pressure gauge body by a film, the front end of the rear cover is provided with a mounting groove, and the bottom of the mounting groove is provided with two sliding grooves;

[0006] Spring grooves are provided on both sides of the two slide grooves, and springs are provided in the two spring grooves. A retaining piece is abutted on one side of the spring, and a retaining ball is provided on the side of the retaining piece away from the spring, and the retaining ball extends to the outside of the slide groove.

[0007] The protective buckle cover includes a sliding cover, and a sliding base is provided at the bottom of the sliding cover. The sliding cover engages and slides with the mounting groove. The sliding base is slidably connected to the groove. Through holes are provided on both sides of the sliding base, and the through holes can engage with the locking beads after the sliding base slides to the end of the groove.

[0008] By adopting the above technical solution, the fixed base and protective buckle cover at both ends of the gauge body are slidably connected to the sliding seat of the protective buckle cover by the mounting groove and sliding groove of the fixed base. This solves the problem of low installation and disassembly efficiency caused by the need for multiple bolts to fasten the traditional pressure gauge with protective structure. It realizes the rapid sliding assembly of the protective structure, simplifies the operation steps, and improves the convenience of installation and disassembly.

[0009] Furthermore, the through hole can be engaged with the locking bead to fix the fixed base and the protective buckle cover together, and the fixed base and the protective buckle cover can be used to wrap the pressure gauge after they are engaged.

[0010] By adopting the above technical solution, the snap-fit ​​design of the through hole and the ball securely fixes the fixed base and the protective buckle cover and wraps the pressure gauge, solving the problems of insufficient fixing reliability and time-consuming operation caused by the traditional multi-bolt fastening method, ensuring a stable connection between the protective structure and the pressure gauge, and effectively protecting the internal precision components.

[0011] Furthermore, a sealing strip is provided on the back of the sliding cover, and the sealing strip can effectively seal the area after being removed from the back cover.

[0012] By adopting the above technical solution, the sealing strip set on the back of the sliding cover forms an effective seal after the sealing strip contacts the back cover, which solves the problem of external pollutants entering due to poor sealing in traditional protective structures, improves the sealing performance of the protective structure, and ensures the cleanliness of the internal environment of the pressure gauge.

[0013] Furthermore, a heating film is provided on the inner wall of the sliding cover, a wiring port is provided on one side of the sliding cover, and a button is provided on one side of the wiring port.

[0014] By adopting the above technical solution, the heating film, wiring port, and button on the inner wall of the sliding cover cover the inner area of ​​the viewing port with the heating film and connect to the power supply through the wiring port and control the opening and closing of the button. This solves the problem of fogging in the viewing port in humid environments, which leads to unclear dial readings. It achieves rapid defogging and ensures visibility.

[0015] Furthermore, the outer surface of the sliding cover is provided with a viewing opening, and the size of the viewing opening is the same as the size of the dial.

[0016] By adopting the above technical solution, and by setting a viewing port of the same size as the dial on the outer surface of the sliding cover, the visible area of ​​the dial is ensured to be unobstructed. This solves the problem of reading difficulties caused by unreasonable viewing window design in traditional protective structures, and improves the convenience and accuracy of observation.

[0017] Furthermore, a dial is provided on the outer surface of the watch body, and a connector is provided on the bottom of the watch body.

[0018] By adopting the above technical solution, a standard data display and installation interface is provided through the dial set on the outer surface of the gauge body and the connector at the bottom, which solves the problem of poor compatibility caused by the non-uniform structure of traditional pressure gauges and ensures the functional integrity and installation adaptability of the pressure gauge.

[0019] Furthermore, the process of the slide block sliding along the slide groove and finally engaging with the locking bead through the through hole constitutes a one-way operation mechanism for the protective cover to be fastened and locked to the fixed base, which simplifies the opening and closing operation of the protective structure and ensures the stable maintenance of the fastening state.

[0020] By adopting the above technical solution, the process of sliding the slide block along the slide groove and finally engaging with the locking bead through the through hole constitutes a one-way operation mechanism for the protective buckle cover to be fastened and locked to the fixed base. This solves the problem of multiple operation steps and low efficiency in the traditional multi-bolt fastening method, and realizes the rapid locking and stable maintenance of the protective structure.

[0021] Furthermore, the working area of ​​the heating film covers or corresponds to the inner range of the viewing port, so that when the sliding cover is fastened to the watch body, the heating effect of its inner wall can directly act on the outer surface of the visible area of ​​the dial corresponding to the viewing port, which can effectively perform defogging.

[0022] By adopting the above technical solution, the working area of ​​the heating film covers or corresponds to the inner range of the viewing port, so that the heating effect during the fastening is directly applied to the outer surface of the visible area of ​​the dial corresponding to the viewing port. This solves the problems of low efficiency and poor effect of traditional defogging methods, and achieves fast and accurate defogging, ensuring clear readings.

[0023] In summary, the present invention has the following main advantages:

[0024] This utility model solves the technical problem of existing pressure gauges with protective structures having low installation and disassembly efficiency due to the use of multiple bolts to fasten the outer shell, requiring operators to spend a lot of time loosening and tightening the bolts one by one, thus increasing the difficulty of maintenance and disassembly. The fixed base and protective buckle cover are equipped with a sliding snap-fit ​​structure. The fixed base has a groove with a snap-fit ​​ball in the mounting slot. The sliding seat of the protective buckle cover slides through the groove and uses a through hole to snap-fit ​​the snap-fit ​​ball to achieve one-way locking.

[0025] This invention solves the technical problem of unclear dial readings caused by fogging in the visible area of ​​existing pressure gauges with protective structures in humid environments. The design incorporates a heating film, a wiring port, and a button on the inner wall of a sliding cover. The heating film covers the inner area of ​​the visible area and is connected to an external power source via the wiring port. The button controls the heating on / off state. This design achieves efficient defogging by directly heating the visible area, and combined with convenient power connection and one-button control, ensures the visibility and operational reliability of the pressure gauge under complex operating conditions.

[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0032] Example 1: A pressure gauge with a protective structure, such as Figure 1-4 As shown, the pressure gauge 1 includes a gauge body 101. The front and rear ends of the gauge body 101 are respectively provided with a fixed base 2 and a protective buckle cover 3. The fixed base 2 includes a rear cover 201. The rear cover 201 is attached to the gauge body 101 by a film. The front end of the rear cover 201 is provided with a mounting groove 202, and the bottom of the mounting groove 202 is provided with two sliding grooves 203.

[0033] Spring grooves 204 are provided on both sides of the two slide grooves 203. Springs 205 are provided in the two spring grooves 204. Abutment piece 206 abuts against one side of the spring 205. A retaining bead 207 is provided on the side of the abutment piece 206 away from the spring 205, and the retaining bead 207 extends to the outside of the slide groove 203.

[0034] The protective cover 3 includes a sliding cover 301, with a slide base 307 at the bottom of the sliding cover 301. The sliding cover 301 engages and slides with the mounting groove 202. The slide base 307 is slidably connected to the sliding groove 203. Through holes 306 are provided on both sides of the slide base 307, and after the slide base 307 slides to the end of the sliding groove 203, the through holes 306 can engage with the retaining beads 207. The protective cover 3 is provided with fixed bases 2 at the front and rear ends of the watch body 101, wherein the front end of the rear cover 201 of the fixed base 2 is provided with a mounting groove 207. 2. The bottom of the mounting slot 202 is provided with two sliding grooves 203, and the bottom of the sliding cover 301 of the protective buckle cover 3 is provided with a sliding seat 307. The sliding seat 307 is slidably connected to the sliding groove 203. This solves the technical problem that the traditional protective structure pressure gauge uses multiple bolts to fasten the outer shell, which requires loosening / tightening the bolts one by one during installation and disassembly, resulting in low efficiency and cumbersome operation. It realizes the rapid assembly of the protective structure by sliding, and can complete the installation and disassembly without complicated tools, which significantly simplifies the operation steps and reduces the maintenance difficulty.

[0035] See Figure 1 , Figure 3 , Figure 4 After the through hole 306 and the locking ball 207 are engaged, the fixed base 2 and the protective cover 3 can be fixed and engaged. After the fixed base 2 and the protective cover 3 are engaged, they can be used to wrap the pressure gauge 1. Through the engagement design of the through hole 306 and the locking ball 207, the through hole 306 and the locking ball 207 are engaged after the slide 307 slides to the end of the slide groove 203, so that the fixed base 2 and the protective cover 3 are reliably fixed and the pressure gauge 1 is wrapped. This solves the technical problems of insufficient fixed reliability of traditional protective structure pressure gauges due to multiple bolts, such as bolt stripping, loosening, and the need to tighten / loosen bolts one by one during operation. It ensures a stable connection between the protective structure and the pressure gauge, effectively isolates the intrusion of external dust, water vapor, etc., and protects the normal operation of internal precision components.

[0036] Example 2: See Figure 3 , Figure 4 A sealing strip 303 is provided on the back of the sliding cover 301. The sealing strip 303 can effectively seal the back cover 201 after it is released from the back cover 201. The sealing strip 303 on the back of the sliding cover 301 forms an effective seal after it comes into contact with the back cover 201. This solves the technical problem of external dust, water vapor, and corrosive media entering the interior of traditional pressure gauges with protective structures due to imperfect sealing design, such as bolt gaps and shell gaps. It improves the sealing performance of the protective structure and ensures that the precision components inside the pressure gauge, such as the movement and Bourdon tube, are in a clean and dry working environment, thus ensuring measurement accuracy and service life.

[0037] See Figure 1 , Figure 2The inner wall of the sliding cover 301 is provided with a heating film 304, and a wiring port 305 is provided on one side of the sliding cover 301. A button 308 is provided on one side of the wiring port 305. The heating film 304 on the inner wall of the sliding cover 301, the wiring port 305 on one side, and the button 308 are used to control the heating on and off. The heating film 304 covers the inner area of ​​the visible port 302. The wiring port 305 is connected to an external power source, and the button 308 controls the heating on and off. This solves the technical problem that the visible port 302 of the traditional pressure gauge with protective structure is prone to fogging due to condensation in humid environments such as high humidity and large temperature difference, which makes the reading of the dial 102 unclear. It realizes rapid defogging by directly heating the visible area, ensuring that the operator can clearly observe the dial data and improving the reliability of the pressure gauge in complex working conditions.

[0038] See Figure 1 , Figure 2 The outer surface of the sliding cover 301 is provided with a viewing port 302, and the size of the viewing port 302 is the same as that of the dial 102. The viewing port 302 provided on the outer surface of the sliding cover 301 is exactly the same size as the dial 102, which ensures that the visible area of ​​the dial 102 is unobstructed. This solves the technical problem that traditional pressure gauges with protective structures have difficulty for operators to read the data due to the small size of the viewing window, the offset position, or the obstruction of key data on the dial. It improves the convenience and accuracy of observation, and enables operators to quickly and clearly obtain the pressure gauge measurement data.

[0039] See Figure 3 , Figure 4 The outer surface of the gauge body 101 is provided with a dial 102, and the bottom of the gauge body 101 is provided with a connector 103. The dial 102 on the outer surface of the gauge body 101 and the connector 103 at the bottom are used to display pressure data. The dial 102 is used to display pressure data, and the connector 103 is used to connect to pipelines or equipment. It provides a standard data display and installation interface, which solves the technical problems of poor compatibility and difficult installation caused by non-standard dial design or inconsistent connector size of traditional pressure gauges. It ensures the functional integrity of the pressure gauge, accurately displays pressure values, and has good installation adaptability and can be quickly connected to various equipment or pipelines.

[0040] See Figure 1 , Figure 4The process of the slide block 307 sliding along the slide groove 203 and finally engaging with the locking bead 207 through the through hole 306 constitutes a one-way operation mechanism for the protective cover 3 to engage and lock the fixed base 2. This simplifies the opening and closing operation of the protective structure and ensures the stable maintenance of the engaged state. The process of the slide block 307 sliding along the slide groove 203 and finally engaging with the locking bead 207 through the through hole 306 constitutes a one-way operation mechanism for the protective cover 3 to engage and lock the fixed base 2. This solves the technical problem of low efficiency caused by repeated adjustments and multiple tightening steps required by traditional pressure gauges with protective structures due to multiple bolts. It enables the protective structure to be locked by one-way sliding, which is simple and quick to operate. The state is stable after engagement, avoiding protection failure due to loose bolts and improving the reliability of use.

[0041] See Figure 1 , Figure 2 The working area of ​​the heating film 304 covers or corresponds to the inner range of the viewing port 302, so that when the sliding cover 301 is fastened to the body 101, the heating effect of its inner wall can directly act on the outer surface of the visible area of ​​the dial 102 corresponding to the viewing port 302, which can effectively perform defogging. By having the working area of ​​the heating film 304 cover or correspond to the inner range of the viewing port 302, the heating effect of its inner wall can directly act on the outer surface of the visible area of ​​the dial 102 corresponding to the viewing port 302 when the sliding cover 301 is fastened to the body 101, which solves the technical problems of traditional defogging methods such as manual wiping and indirect heating having low efficiency, poor effect and easy residual fog. It realizes the rapid removal of condensed fog by directly heating the visible area, ensuring clear reading of the dial 102 and improving the reliability of the pressure gauge in humid environments.

[0042] The implementation principle of this embodiment is as follows: First, align the slide 307 of the protective buckle cover 3 with the slide groove 203 of the fixed base 2, and push the sliding cover 301 along the direction of the slide groove 203 so that the slide 307 slides in the slide groove 203; at this time, the spring 205 pushes the abutment piece 206 and the retaining bead 207 to move inward to the inside of the slide groove 203, and the retaining bead 207 is squeezed back into the spring groove 204 by the side wall of the slide 307.

[0043] When the slide block 307 slides to the end of the slide groove 203, the through holes 306 on both sides of the slide block 307 align with the position of the retaining ball 207; the spring 205 releases its elastic force, pushing the abutment piece 206 to make the retaining ball 207 embed into the through hole 306, thereby achieving automatic locking and fastening between the fixed base 2 and the protective cover 3. At this time, the sliding cover 301 completely covers the pressure gauge 1 body 101, and the sealing strip 303 and the rear cover 201 are tightly fitted to form a sealing interface, isolating external contaminants.

[0044] In low temperature and high humidity environments, if frost or fog appears on the outer surface of the dial 102 corresponding to the viewing port 302, power is supplied to the heating film 304 through the wiring port 305, and the heating function is activated by pressing the button 308; the heat of the heating film 304 directly acts on the inner wall of the sliding cover 301 and the area corresponding to the viewing port 302, quickly eliminating condensation or fog in the visible area of ​​the dial 102, ensuring clear readings.

[0045] During disassembly, push the sliding cover 301 in the opposite direction. The slide block 307 will press the retaining bead 207 to disengage it from the through hole 306 and compress the spring 205. The slide block 307 will then exit along the slide groove 203 to separate the protective buckle cover 3.
