Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figures 1-5 This utility model provides a vibration-resistant pressure gauge mechanism, including a main body component 1, an indicator component 2 is provided inside the main body component 1, a drive component 3 is provided on the indicator component 2, the indicator component 2 and the drive component 3 cooperate to measure the pressure of gas or liquid in the pipeline, and a limit component 4 is provided on the drive component 3 to limit the drive component 3. The main component 1 includes a housing 11, a fixing seat 12 is provided on the housing 11, a connecting pipe 13 is provided on the fixing seat 12, and the connecting pipe 13 communicates with the inside of the housing 11. A flexible hose 14 is provided on the connecting pipe 13.

[0018] Specifically, when measuring the pressure of gas or liquid inside a pipeline, the hose 14 can be connected to the pipeline, and the outer casing 11 can be connected to an external fixed structure. This prevents the internal structure of the outer casing 11 from vibrating due to pipeline vibration during subsequent measurements, thus avoiding inaccurate measurement results. In use, the indicator component 2 and the drive component 3 can be used together to perform precise pressure measurements of gas or liquid inside the pipeline. Furthermore, the stable setting of the drive component 3 prevents vibration caused by shaking during use, thus avoiding inaccurate measurements.

[0019] In this embodiment, the main component 1 also includes a protective plate 15, which is disposed on the outer shell 11. The outer shell 11 is provided with a filling plug 16 and an overflow hole 17.

[0020] Specifically, during use, a protective plate 15 can be installed on the outer casing 11 to protect the internal structure of the outer casing 11. During use, a filling plug 16 and an overflow hole 17 can be installed on the outer casing 11 to prevent excessive pressure inside the outer casing 11.

[0021] In this embodiment, the indicating component 2 includes a U-shaped component 21, which is disposed inside the housing 11. A spring tube 22 is disposed on the U-shaped component 21. A connector 29 is disposed on the housing 11. An A gear 24 is disposed on the connector 29. A deflector 27 is disposed on the housing 11, and the deflector 27 meshes with the A gear 24.

[0022] Specifically, during measurement, when the Bourdon tube 22 deforms, the drive assembly 3 can drive the A gear 24 to rotate, which in turn can drive the indicator 23 to deflect. By cooperating with the scale set on the housing 11, the pressure inside the pipeline can be determined.

[0023] In this embodiment, a torsion spring 25 and a positioning rod 26 are provided on the outer casing 11. The torsion spring 25 is connected to the positioning rod 26 and the connecting member 29 respectively. A limit member 28 is provided on the outer casing 11, and an indicator member 23 is provided on the A gear 24.

[0024] Specifically, in use, in order to ensure that the indicator 23 can deflect in the opposite direction after the measurement is completed and the spring tube 22 returns to its original shape, a positioning rod 26 can be set inside the housing 11, and the positioning rod 26 and the connecting member 29 can be connected by a torsion spring 25. After the measurement is completed, the torsion spring 25 will drive the connecting member 29 to deflect in the opposite direction under its own elastic force, thereby driving the indicator 23 to deflect in the opposite direction.

[0025] In this embodiment, the drive assembly 3 includes a B extension 32, which is disposed on the deflector 27. An extension 34 is disposed on the spring tube 22, and the B extension 32 and the extension 34 are hinged together by a hinge shaft 33.

[0026] Specifically, in actual use, when the spring tube 22 deforms, an extension 34 can be provided at the end of the limiting member 28, and an extension 32 B can be provided on the deflecting member 27. The two are hinged by the hinge shaft 33, so that when the limiting member 28 deforms, it can drive the deflecting member 27 to deflect, thereby driving the gear A 24 to rotate.

[0027] In this embodiment, the drive assembly 3 further includes an A extension 31, which is disposed on the deflector 27. A hollow part 35 is disposed on the A extension 31, and a rotating hole is provided on the A extension 31, which penetrates the surfaces of the A extension 31 and the hollow part 35. A sliding part 36 is disposed inside the hollow part 35, and an abutment part 37 is disposed on the sliding part 36. A B gear 39 is disposed inside the hollow part 35, and a rack 38 is disposed on the sliding part 36. The rack 38 meshes with the B gear 39.

[0028] Specifically, in order to ensure that the hinge shaft 33 and the extension member B are stably set during use and to prevent them from falling off or loosening during subsequent measurements, thus avoiding shaking or vibration, an extension member A 31 can be set on the deflector 27, a hollow member 35 can be set on the extension member A 31, a slider 36 can be slidably set inside the hollow member 35, an abutment member 37 can be set on the slider 36, and a rack 38 can be set on the slider 36. Then, by rotating the gear B 39, the slider 36 can be moved, so that the abutment member 37 can abut against the hinge shaft 33, thereby preventing the hinge shaft 33 from shaking and thus avoiding vibration.

[0029] In this embodiment, the limiting component 4 includes a delay rod 43, which is disposed on the B gear 39 and is disposed in the rotating hole. A ratchet 41 is disposed on the delay rod 43, and a ratchet 42 is disposed on the A extension 31, and the ratchet 42 engages with the ratchet 41.

[0030] Specifically, in order to prevent the B gear 39 from reversing and causing the slider 36 to move, a delay rod 43 can be set on the B gear 39, and the delay rod 43 extends out of the rotation hole. A ratchet 41 is set on the delay rod 43, and the ratchet 42 engages with the ratchet 41, thereby preventing the slider 36 from moving.

[0031] Working principle and usage process of this utility model: When measuring the pressure of gas or liquid inside a pipeline, the hose 14 can be connected to the pipeline and the outer casing 11 can be connected to an external fixed structure. This prevents the structure inside the outer casing 11 from vibrating due to pipeline vibration during subsequent measurements, thus avoiding inaccurate measurement results.

[0032] During measurement, when the Bourdon tube 22 deforms, the drive assembly 3 drives the gear A 24 to rotate, which in turn drives the indicator 23 to deflect. The indicator 23 cooperates with the scale set on the housing 11 to determine the pressure inside the pipeline. In order to ensure that the indicator 23 can deflect in the opposite direction after the measurement is completed and the Bourdon tube 22 returns to its original shape, a positioning rod 26 is set inside the housing 11, and a torsion spring 25 connects the positioning rod 26 and the connector 29. After the measurement is completed, the torsion spring 25 will drive the connector 29 to deflect in the opposite direction under its own elastic force, which in turn drives the indicator 23 to deflect in the opposite direction.

[0033] In practical use, when the spring tube 22 deforms, an extension 34 can be provided at the end of the limiting member 28, and a B extension 32 can be provided on the deflecting member 27. The two are hinged together by a hinge shaft 33. This allows the limiting member 28 to deform, causing the deflecting member 27 to deflect, which in turn drives the A gear 24 to rotate. During use, to ensure a stable connection between the hinge shaft 33 and the B extension 32, and to prevent them from detaching or loosening during subsequent measurements, [further details are needed]. To prevent shaking or vibration, an extension A 31 can be provided on the deflector 27, a hollow part 35 can be provided on the extension A 31, a slider 36 can be slidably provided in the hollow part 35, an abutment 37 can be provided on the slider 36, and a rack 38 can be provided on the slider 36. Then, by rotating the gear B 39, the slider 36 can be moved, so that the abutment 37 can abut against the hinge shaft 33, thereby preventing the hinge shaft 33 from shaking and thus preventing vibration.

[0034] The electronic components and modules used in this utility model can all be parts that are commonly used in the market and can achieve the specific functions in this case. The specific models and sizes can be selected and adjusted according to actual needs.
