[0025] Example 1: As shown in the attached document Figure 1 To be continued Figure 6 As shown:

[0026] This utility model provides a durable gas meter with a waterproof and dustproof outer shell, comprising: a gas meter 1, an integral rear shell 2 fixedly connected to the rear side wall of the gas meter 1, a protective front shell 5 inserted into the front side of the integral rear shell 2, a sealing gasket 4 snapped between the integral rear shell 2 and the protective front shell 5, the sealing gasket 4 having an elliptical cross-section, a baffle plate 6 slidably connected to the bottom end face of the protective front shell 5, and sealing rings 3 fitted around the two symmetrical connection ports on the top of the gas meter 1, the top of the sealing rings 3 being conical, a connecting retainer 301 being provided in the middle of the outer side wall of the sealing rings 3, the connecting retainer 301 being snapped into the sealing groove 201 opened on the top of the integral rear shell 2 and the arc groove opened on the rear side of the top of the protective front shell 5, the integral rear shell 2 and the protective front shell 5 being made of a high-strength waterproof and dustproof composite material. Made of a mixture of polycarbonate, EPDM rubber, and nano-silica particles, the integrated rear shell 2 and protective front shell 5 are interlocked and sealed by a sealing gasket 4. The elliptical sealing gasket 4 forms a tight seal under the interlocking compression, effectively preventing external moisture and dust from entering the gas meter 1. The baffle 6 at the bottom of the protective front shell 5 can flexibly control the bottom opening state to meet ventilation or protection needs. The conical design at the top of the sealing ring 3 facilitates the guidance of rainwater to slide off and prevents rainwater accumulation. The cooperation between the connecting ring 301 and the sealing groove 201 and the arc groove further enhances the sealing performance at the top connection. The high-strength waterproof and dustproof composite material combines the high strength of polycarbonate, the high elasticity of EPDM rubber, and the waterproof and dustproof properties of nano-silica particles, improving the protective performance and durability of the gas meter 1 shell from a material perspective.

[0027] The integrated rear shell 2 has two symmetrical semi-circular sealing grooves 201 on the top of its front side wall. Connecting rods 202 are symmetrically arranged on both sides of the inner rear wall of the integrated rear shell 2. The bottom of the integrated rear shell 2 is shaped with a lower front and a higher rear. Specifically, the semi-circular sealing grooves 201 are adapted to the connecting rings 301 of the sealing sleeve 3 to form a stable and well-sealed connection structure, further enhancing the top's waterproof and dustproof performance. The connecting rods 202 on the inner rear wall provide insertion and positioning for the combination rods 502 of the protective front shell 5, facilitating the precise assembly and stable connection between the protective front shell 5 and the integrated rear shell 2. The lower front and higher rear shape of the bottom facilitates the rapid flow and drainage of accumulated water to the lower bottom, preventing water residue inside the shell and further improving waterproof performance.

[0028] The protective front shell 5 has an observation window 501 fixed in the middle of its front side wall. The observation window 501 is made of transparent acrylic and its front and rear side walls are arc-shaped to form a convex lens structure. The protective front shell 5 has symmetrical combination rods 502 on both sides of its front inner wall. The rear end of the combination rod 502 is inserted into the front end of the connecting rod 202 of the integrated rear shell 2. A connecting screw 7 is inserted into the combination rod 502, and the rear end of the connecting screw 7 is threaded into the connecting rod 202. Specifically, the transparent acrylic observation window 501 has good light transmission and wear resistance, and the arc-shaped convex lens structure can magnify the display content, making it easier for users to clearly read the data of the gas meter 1. The insertion and cooperation of the combination rod 502 and the connecting rod 202, combined with the threaded connection of the connecting screw 7, makes the connection between the protective front shell 5 and the integrated rear shell 2 more secure, enhances the overall structural strength of the shell, improves durability, and effectively resists external impacts and pressure.

[0029] The protective front shell 5 has a rectangular array of ventilation holes 503 on its bottom end face. A sliding cavity 504 is located at the bottom of the protective front shell 5, and a baffle plate 6 is slidably connected to the sliding cavity 504. A control rod 601 is fixedly connected to the middle of the baffle plate 6, and the front end of the control rod 601 is slidably connected to the bottom front side wall of the protective front shell 5. Two arc grooves are symmetrically formed on the rear top of the protective front shell 5. Specifically, the rectangular array of ventilation holes 503 meets the internal ventilation and heat dissipation needs of the gas meter 1, preventing excessive temperature from affecting performance due to the heat generated by internal components. The baffle plate 6 cooperates with the sliding cavity 504, and the control rod 601 can flexibly control the opening and closing of the ventilation holes 503. When protection is needed, the ventilation holes 503 are closed to prevent external moisture, dust, and foreign objects from entering; when ventilation is needed, they are opened, achieving a switch between ventilation and protection functions. The arc grooves on the rear top cooperate with the connecting ring 301 of the sealing sleeve 3 to further ensure the sealing performance and structural stability of the top connection.

[0030] The specific usage and function of this embodiment are as follows:

[0031] When using this durable gas meter with a waterproof and dustproof casing, first fix the integrated rear shell 2 of the gas meter 1 in a suitable installation position. Then, use the connecting rod 202 on its rear inner wall to insert and position it with the combination rod 502 on the front inner wall of the protective front shell 5. Next, use the connecting screw 7 to pass through the combination rod 502 and thread it onto the connecting rod 202 to complete the main casing assembly. During installation, the elliptical sealing gasket 4 at the connection between the integrated rear shell 2 and the protective front shell 5 is compressed to form a tight seal. Simultaneously, fit the sealing ring 3 onto the top connection port of the gas meter 1, making the connection clip... Ring 301 is inserted into the sealing groove 201 at the top of the integrated rear shell 2 and the arc groove on the rear side of the top of the protective front shell 5 to enhance the top sealing. In daily use, users can read data through the observation window 501 on the front side wall of the protective front shell 5. If the gas meter 1 needs heat dissipation, pull the control lever 601 to slide the shield 6 to open the ventilation hole 503. If protection is needed, push the shield 6 to close the ventilation hole 503. The design of the bottom of the integrated rear shell 2, which is lower in the front and higher in the back, allows water that enters the shell to automatically flow to the lower part and be discharged, ensuring that the gas meter 1 is waterproof, dustproof, stable and durable in complex environments.

[0032] Example 2:

[0033] A positioning slot is added to the connecting rod 202 on the inner rear wall of the integrated rear shell 2. Correspondingly, a positioning block is set at the rear end of the combination rod 502 of the protective front shell 5. During installation, the positioning block at the rear end of the combination rod 502 is aligned with the positioning slot on the connecting rod 202 and inserted, and then fixed by the connecting screw 7. This design can further ensure the precise docking of the protective front shell 5 and the integrated rear shell 2 during the assembly process, avoid misalignment when tightening the connecting screw 7, enhance the stability of the connection, improve the overall structural strength, and make the outer shell connection part less prone to loosening when the gas meter 1 is subjected to vibration or slight impact, effectively ensuring the safety of the internal gas meter 1.
