[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Reference Figure 1FIG2 shows an embodiment of the present invention: an ultrasonic gas meter module test fixture comprising a base plate 1, with a restraining assembly for restraining components fixedly connected to the top of the base plate 1. The restraining assembly is designed to ensure that each component is securely fixed during testing, thereby avoiding testing errors caused by component movement. Fixed rods 4 are fixedly connected to both sides of the top of the base plate 1. The fixing rods 4 are made of a high-strength alloy material and can provide sufficient support to meet the testing requirements of different gas meter modules while increasing the durability of the fixture. Springs 1 (5) are sleeved on both ends of the outer ends of the fixing rods 4. The springs 1 (5) have good elasticity and can be compressed when external force is applied and reset when the external force is released, thereby effectively positioning the moving block 6. One end of the spring 1 (5) is fixedly connected to the inner wall of one side of the base plate 1, and the other end of the spring 1 (5) is fixedly connected to one side of the moving block 6. This connection method ensures that the spring 1 (5) provides a uniform reaction force when the moving block 6 moves, thereby ensuring the stability and accuracy of the moving block 6 during testing.

[0032] The outer portion of the moving block 6 is slidably connected to the inner wall of the base plate 1. The moving block 6 is made of a polymer material with a low friction coefficient, ensuring that no jamming occurs during the sliding process, thereby improving the smoothness of the test. The tops of the two moving blocks 6 are fixedly connected to a support platform 7. The support platform 7 adopts a lightweight design and is made of aluminum alloy material. It not only ensures the support strength but also reduces the weight of the entire tooling, making it easier for operators to use. The top of the support platform 7 is fixedly connected to a positioning block 8. The shape of the positioning block 8 matches the bottom structure of the gas meter housing 13. This design ensures that the gas meter housing 13 can be accurately fixed on the support platform 7 to avoid offset or shaking during the test.

[0033] The top of the limiting assembly is rotatably connected to two rotating plates 9, which are connected via precision bearings, ensuring smoothness during rotation while reducing the impact of friction on test accuracy. The limiting assembly includes a slide rail 2, the bottom of which is fixedly connected to the top of the base plate 1. The slide rail 2 is made of stainless steel with a polished surface, exhibiting excellent corrosion resistance and capable of long-term use in humid or corrosive environments without affecting performance. Sliding blocks 3 are slidably connected to both sides of the top of the slide rail 2, the top of the slide block 3 being fixedly connected to the bottom of the support platform 7. The slide block 3 can move smoothly along the slide rail 2, allowing the support platform 7 to flexibly adjust its position to accommodate gas meter housings 13 of different sizes.

[0034] The bottom of the rotating plate 9 is pivotally connected to the top of the slide rail 2. Limiting blocks 10 are pivotally connected to both sides of the top of the rotating plate 9. The structural design of the limiting blocks 10 allows them to be precisely embedded in the support platform 7, thereby ensuring the stability of the gas meter housing 13 during testing. Limiting grooves 11 are provided on both sides of the support platform 7. The depth and width of the limiting grooves 11 have been precisely calculated to closely match the limiting blocks 10 and prevent displacement of the gas meter housing 13 during testing.

[0035] The right end of the base plate 1 is provided with a gas inlet 12. This inlet 12 is designed with airtightness and ease of operation in mind, utilizing high-precision seals to ensure no gas leakage during testing, thereby guaranteeing the accuracy of the test results. The gas meter housing 13 is coupled to the adjacent sides of the two positioning blocks 8. The bottom of the housing 13 contacts the tops of the two support platforms 7. This design ensures that the weight of the housing 13 is evenly distributed across the support platforms 7, further enhancing the stability of the test fixture.

[0036] refer to Figure 3 and Figure 4 The left end of the gas meter housing 13 is fixedly connected to connecting pipes 14 on both sides. The design of the connecting pipes 14 takes into account the firmness and airtightness of the connection, and adopts a threaded connection method to ensure that no leakage occurs under high pressure. The external thread connection of the connecting pipe 14 is used to seal the connecting pipe 14. Each sealing component includes a sealing cover 16. The sealing cover 16 is made of high-temperature resistant material and can maintain good sealing performance under high-temperature test conditions to ensure the reliability of the test data. The left end of the sealing cover 16 is rotatably connected to the air pipe 15. The air pipe 15 is made of a high-pressure resistant hose with excellent pressure resistance. It can withstand high-pressure gas during testing and ensure safe operation. The other end of the air pipe 15 is fixedly connected to the left end of the base plate 1 to ensure stable connection of the entire air path system. The inflation port 12 is connected to one of the air pipes 15. A threaded groove 17 is provided inside the sealing cover 16. The design of the threaded groove 17 ensures that the sealing component can fit tightly with the connecting pipe 14, thereby improving the sealing of the system.

[0037] A spring 2 18 is fixedly connected to the inner wall of one side of the threaded groove 17. The spring 2 18 can provide appropriate elastic force to keep the push block 19 in close contact with the connecting pipe 14 at all times, avoiding gas leakage caused by external forces. The other end of the spring 2 18 is fixedly connected to the push block 19. The outer portion of the push block 19 is slidably connected to the inner wall of the threaded groove 17. The design of the push block 19 takes into account the wear resistance and stability of the material to ensure that it will not become loose or worn during long-term use, affecting the sealing effect on the connecting pipe 14. The right end of the push block 19 is in contact with the left end of the connecting pipe 14. This design of the push block 19 enables the connecting pipe 14 to always remain in the center position of the sealing cover 16, further improving the airtightness of the entire system. The inner wall of the threaded groove 17 is threadedly connected to the outside of the connecting pipe 14. This connection method ensures the stability of the installation and the convenience of disassembly.

[0038] Working principle: When the equipment needs to be used, by pulling one of the positioning blocks 8, the movement of the positioning block 8 can drive the support platform 7 to move, and when the support platform 7 moves, it can drive the moving block 6 to move outside the fixed rod 4, and the movement of the moving block 6 can squeeze the spring 15, so that the spring 15 generates elastic potential energy, and when the support platform 7 moves, the limiting block 10 can slide on the inner wall of the limiting groove 11. At this time, the sliding of the limiting block 10 will also drive the rotating plate 9 to rotate, so that the rotation of the rotating plate 9 can push the support platform 7 on the other side to move. At this time, the gas meter housing 13 is placed on the top of the support platform 7, and the positioning block 8 is released. At this time, the spring 15 will release the elastic potential energy, thereby pushing the moving block 6 to move the moving block 6 inward for reset, so that the movement of the moving block 6 can drive the support platform 7 to move, and the movement of the support platform 7 can drive the positioning block 8 to move. Finally, the movement of the positioning block 8 can fix the gas meter housing 13, greatly shortening the time for module testing and calibration.

[0039] At this time, align the sealing cover 16 with the connecting pipe 14, and then rotate the sealing cover 16 to make the connecting pipe 14 enter the thread groove 17. When the connecting pipe 14 continues to enter the thread groove 17, the thread groove 17 will press against the push block 19, so that the push block 19 pushes the spring 2 18. At this time, the spring 2 18 will generate elastic potential energy, which can act on the push block 19 through the elastic potential energy of the spring 2 18, so that the push block 19 generates a force to push the connecting pipe 14, thereby improving the sealing effect between the push block 19 and the connecting pipe 14, and ensuring the accuracy of the sealing detection structure. Finally, the gas is sent into the gas meter housing 13 from the inflation port 12 through the detection equipment to detect the sealing effect of the gas meter housing 13.

[0040] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
