[0002] In industrial production, hydraulic systems, pneumatic equipment and other fields, pressure gauges are key instruments used to monitor pressure parameters. Their housing structure directly affects the sealing performance, installation adaptability, ease of reading and service life of the pressure gauge.

[0003] Currently available pressure gauge housings mostly suffer from insufficient sealing performance, making them prone to air and water leaks in humid, dusty, or corrosive environments, leading to damage to internal components. Installation methods are also limited, allowing only threaded or wall-mounted mounting, failing to adapt to diverse installation needs. The observation windows are often made of ordinary glass, prone to fogging and glare, affecting the accuracy of pressure readings. Some components use fixed connections, making disassembly and maintenance inconvenient, and the stability of the observation window's fixing structure is insufficient, potentially leading to loosening after prolonged use. Furthermore, the inappropriate material selection for sealing components results in a short seal lifespan, failing to meet the requirements for long-term stable operation of pressure gauges under complex working conditions, thus limiting applicability and practicality. Therefore, those skilled in the art provide a pressure gauge housing structure to solve the problems mentioned in the background art. Utility Model Content

[0025] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0026] Please see the appendix Figure 1 Appendix Figure 2 As shown, a pressure gauge housing structure includes a housing body 1, an end cap 2, a sealing assembly 3, a mounting assembly 4, an observation window assembly 5, and a fixing seat 6. The end cap 2 is detachably connected to the housing body 1. The sealing assembly 3 is disposed between the housing body 1 and the end cap 2 to achieve a seal. The sealing assembly 3 includes a sealing ring 31 and a sealing gasket 32. The mounting assembly 4 is connected to the housing body 1 to achieve installation and fixation in multiple scenarios. The observation window assembly 5 is fixed to the outer end of the end cap 2 to facilitate observation of the internal pointer reading of the pressure gauge. The fixing seat 6 is disposed on the top of the housing body 1 and is used to connect the mounting assembly 4.

[0027] The main body 1 of the shell should be made of high-strength cast iron or aluminum alloy to balance structural strength and corrosion resistance, and ensure that it is not easily deformed during long-term use; the end cap 2 should be made of a metal material that is compatible with the main body 1 of the shell to ensure the stability of the overall structure and facilitate processing and forming.

[0028] As one implementation method in this embodiment, please refer to the appendix. Figure 2 Appendix Figure 3 and attached Figure 6 As shown, the end cap connecting surface of the housing body 1 has an annular sealing groove 11. A sealing ring 31 is embedded in the sealing groove 11, and a sealing gasket 32 ​​is located between the observation window assembly 5 and the end cap 2. The sealing gasket 32 ​​is made of silicone, which has good elasticity and sealing performance. The sealing ring 31 is made of fluororubber, which is resistant to high and low temperatures and has strong corrosion resistance, making it suitable for complex working environments. The size of the sealing groove 11 must be precisely matched with the sealing ring 31 to ensure that the sealing ring 31 is not loose after being installed. Through the double seal of the sealing ring 31 and the sealing gasket 32, external moisture, dust and other impurities are effectively blocked from entering the housing, protecting the internal pressure sensing element from damage.

[0029] As one implementation method in this embodiment, please refer to the appendix. Figure 1 Appendix Figure 2 Appendix Figure 3 As shown, the installation component 4 includes a mounting base 41 and a wall-mounted bracket 42. The mounting base 41 is integrally formed with the bottom of the housing body 1. The mounting base 41 is provided with a threaded interface for easy fixed installation via threaded connection. The wall-mounted bracket 42 has an L-shaped structure with a waist-shaped connecting groove 421 on its bottom horizontal plate. The fixing base 6 is provided with a fixing hole 61 that mates with the waist-shaped connecting groove 421. A fixing bolt 43 passes between the waist-shaped connecting groove 421 and the fixing hole 61, and the fixing bolt 43 is threadedly connected to the fixing hole 61. The threaded interface of the mounting base 41 must conform to the general thread standard to improve installation adaptability. The wall-mounted bracket 42 is made of high-strength steel plate bent into shape. The length of the waist-shaped connecting groove 421 needs to be designed according to the adjustment requirements. By loosening the fixing bolt 43, the fixed position of the wall-mounted bracket 42 can be adjusted along the waist-shaped connecting groove 421, thereby adjusting the installation angle and position of the pressure gauge to adapt to different installation scenarios and achieve flexible switching between threaded installation and wall-mounted installation.

[0030] As one implementation method in this embodiment, please refer to the appendix. Figure 2 Appendix Figure 3 Appendix Figure 4 Appendix Figure 5 and attached Figure 6As shown, the outer side of the end cap 2 has an open slot, and the outer end is provided with a connecting protrusion ring 21. The metal pressure ring 52 has an annular structure, with its inner circumferential wall threaded to the outer circumferential wall of the connecting protrusion ring 21. The front end of the metal pressure ring 52 extends towards the axis and is provided with a fixing ring 521. The middle of the fixing ring 521 is provided with an observation port 522 that communicates with the open slot of the end cap 2. The tempered glass 51 is embedded in the annular groove between the rear side of the fixing ring 521 and the end of the connecting protrusion ring 21, and is pressed and fixed by the metal pressure ring 52. The metal pressure ring 52 is made of wear-resistant metal, and the threaded connection structure facilitates disassembly and assembly. When the tempered glass 51 is damaged, the metal pressure ring 52 can be unscrewed and replaced. The size of the annular groove must be precisely matched with the tempered glass 51 to ensure that the tempered glass 51 is stable and does not wobble after being embedded. The fixing ring 521 plays a role in pressing and limiting the tempered glass 51 to prevent it from loosening and falling off after long-term use.

[0031] The inner surface of the tempered glass 51 is coated with an anti-fogging coating, and the outer surface is coated with an anti-reflective coating. The tempered glass 51 must be made of high-strength explosion-proof tempered glass with high light transmittance and is not easily broken. The anti-fogging coating can effectively prevent fogging on the inner surface of the glass when the ambient temperature changes, and the anti-reflective coating reduces the influence of external light reflection on the reading, ensuring that operators can clearly read the pressure gauge value under different lighting and temperature conditions.

[0032] In practical implementation, the following installation methods can be selected according to the installation scenario: If threaded installation is used, the threaded interface of the mounting base 41 can be directly connected and fixed to the threaded seat at the preset installation position; if wall-mounted installation is used, the fixing bolt 43 passes through the waist-shaped connecting groove 421 of the wall-mounted bracket 42 and is threadedly connected to the fixing hole 61 of the fixing base 6 to fix the wall-mounted bracket 42 to the fixing base 6, and then the vertical plate of the wall-mounted bracket 42 is fixed to the wall or mounting bracket. If the position needs to be adjusted, loosen the fixing bolt 43, adjust it to the appropriate position along the waist-shaped connecting groove 421, and then tighten the fixing bolt 43 again.

[0033] After installation, the pressure gauge value can be read through the observation port 522 of the observation window component 5. The anti-fogging coating and anti-reflective coating of the tempered glass 51 ensure clear readings. The sealing ring 31 and sealing gasket 32 ​​of the sealing component 3 effectively prevent external impurities from entering and ensure the normal operation of internal components.

[0034] If you need to disassemble, maintain or replace the tempered glass 51, first unscrew the bolts connecting the main body 1 and the end cover 2, remove the end cover 2, and then unscrew the metal pressure ring 52. You can then take out the tempered glass 51 for replacement or inspect the inside of the housing. After maintenance, reassemble in the reverse order. The operation is convenient and efficient.

[0035] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
