[0031] Embodiment 2
[0032] As shown in Figure 1 , the utility model discloses another technical scheme, mechanical pressure gauge shockproof anti-shake structure, which is different from embodiment 1 in that the inner side wall of the above-mentioned first upper hoop 4 and the first lower hoop 5 is adhered with a first buffer layer 8, the first buffer layer 8 is made of rubber, directly contacts the outer wall of the pipeline, can first absorb and reduce the vibration energy when the vibration is conducted from the pipeline to the connecting hoop group, prevents the energy from being transmitted to the upper pressure gauge body 3 and other components without attenuation, greatly protects the pressure gauge body 3 from the original vibration impact of the pipeline, prolongs the service life of the pressure gauge body 3, and at the same time helps to maintain the measurement accuracy.
[0033] Embodiment 3
[0034] As shown in Figure 1 , 2As shown in Figure 3, this utility model discloses another technical solution: a shock-resistant and vibration-proof structure for a mechanical pressure gauge. The difference from embodiment 1 is that the above-mentioned locking components are provided in four sets, which are respectively located at the four corners of the support base plate 2 to ensure that the support base plate 2 and the T-shaped support plate 1 are tightly and stably connected.

[0035] Example 4:
[0036] like Figure 1 , 4 As shown in Figure 5, this utility model discloses another technical solution: a shock-resistant and vibration-proof structure for a mechanical pressure gauge. The difference from Embodiment 1 is that the locking clamp group includes a second upper clamp 12 and a second lower clamp 13. The second upper clamp 12 and the second lower clamp 13 are semi-circular ring structures corresponding to each other. Both ends of the second upper clamp 12 and the second lower clamp 13 are integrally provided with a second connecting part 14. The first support component is connected to the second connecting part 14. The second upper clamp 12 and the second lower clamp 13 are used to clamp the pressure gauge body 3. They can effectively achieve buffering and support in the vertical direction with the help of the first support component. This is an important structural basis for ensuring the stability of the pressure gauge body 3 in the vertical vibration dimension, ensuring that the pressure gauge body 3 does not undergo large displacement or shaking under complex vibration.
[0037] Specifically, the first support component includes a third locking bolt 15 and a buffer spring 16. The threaded end of the third locking bolt 15 passes through the upper and lower second connecting parts 14 and the support base plate 2 from top to bottom. The third locking bolt 15 should be equipped with a locking nut.

When the pressure gauge body 3 is subjected to vertical vibration, the buffer spring 16 absorbs the vibration energy through its own expansion and contraction deformation, avoiding rigid collision between the pressure gauge body 3 and the support base plate 2. This protects the internal precision components of the pressure gauge body 3 and maintains its relatively static measurement posture, ensuring measurement accuracy. It also works with other components to improve the shock resistance and vibration prevention effect.
[0038] Specifically, the inner sides of the second upper and lower clamps 12 and 13 are symmetrically provided with arc-shaped installation grooves 17 for installing the pressure gauge body 3. The inner side walls of the installation grooves 17 are uniformly circumferentially bonded with a plurality of limiting protrusions 18 along the axis. The limiting protrusions 18 are made of rubber and can limit the rotation, translation and other small displacements of the pressure gauge body 3 in the second upper and lower clamps 12 and 13, protect the internal precision components of the pressure gauge body 3 and prolong its service life.
[0039] Specifically, the middle part of the second lower clamp 13 is provided with a through hole 20 for the interface hose 19 of the pressure gauge body 3 to pass through, which provides a dedicated channel for the interface hose 19 and avoids the interface hose 19 from being squeezed or bent during installation or vibration, ensuring smooth pressure transmission and the structural integrity of the locking clamp group, without affecting the fixation and protection of the pressure gauge body 3, further improving the practicality and adaptability of the device.
[0040] Specifically, the second support assembly includes two symmetrically arranged support blocks 21. The bottom of the support block 21 is fixedly connected to the upper surface of the support base plate 2 through a bolt. The upper surface of the support block 21 is provided with a limiting groove 22 matched with the outer side wall of the second lower clamp 13, which effectively limits the lateral displacement of the locking clamp group and prevents the pressure gauge body 3 from tilting and shaking due to lateral vibration. In cooperation with the first support assembly, it builds a comprehensive three-dimensional protection and resists vibration interference from different directions.
[0041] Specifically, the surface of the limiting groove 22 is bonded with a second buffer layer 23 made of rubber, which can gently offset the impact force and avoid rigid contact damage to the locking clamp group and the pressure gauge body 3, further optimizing the lateral shock resistance and anti-shake performance.
[0042] The mechanical pressure gauge shockproof and anti-shaking structure provided by the utility model can be tightly connected with the pipeline to be detected, the first buffer layer 8 of the inner side wall can effectively buffer the vibration transmitted by the pipeline, the vibration energy directly transmitted to the pressure gauge body 3 is reduced, the pressure gauge body 3 is protected from the influence of the pipeline vibration, the locking assembly is arranged, the support base plate 2 can be stably installed on the T-shaped support plate 1, the stability of the overall structure is guaranteed, meanwhile, the installation and dismounting are facilitated, and the subsequent maintenance and repair are facilitated, the buffer spring 16 in the first support assembly can provide elastic buffering when the pressure gauge body 3 is subjected to the up-down direction vibration, the vibration impact is absorbed, the pressure gauge body 3 is prevented from being damaged due to the rigid collision, meanwhile, the relative stable installation posture of the pressure gauge body 3 is maintained, and the measurement accuracy is ensured, the support block 21 and the limiting groove 22 of the second support assembly stably support the locking hoop assembly from the side, cooperate with the second buffer layer 23, further resist the vibration interference from all directions, the displacement or shaking of the pressure gauge body 3 is prevented, the shockproof and anti-shaking performance of the pressure gauge body 3 in the complex vibration environment is greatly improved, the installation groove 17 and the limiting protruding block 18 in the locking hoop assembly can accurately position the pressure gauge body 3 and limit the displacement of the pressure gauge body 3 in the hoop, and the use of the pressure gauge body in the vibration environment is ensured.
