Description

Technical Field

[0001] This utility model relates to the field of pressure gauges, and in particular to an adjustable damping structure and pressure gauge for a high-sensitivity industrial pressure gauge. Background Technology

[0002] A high-sensitivity industrial pressure gauge is a pressure measuring instrument used in industrial fields. It can accurately and quickly detect minute pressure changes and accurately reflect these changes through internal conversion and transmission mechanisms, such as pointer deflection and digital display, allowing users to clearly read the corresponding pressure values.

[0003] In existing technologies, high-sensitivity industrial pressure gauges typically consist of a body, a connection interface, a sensitive element, and an indicating mechanism. During use, they are connected to the pipe or equipment being measured via the connection interface. The pressure of the measured medium acts on the sensitive element, causing it to deform. This deformation is transmitted to the indicating mechanism via a transmission mechanism, and the pressure value is ultimately displayed by a pointer or digital display unit. To adapt to different operating conditions, some pressure gauges incorporate simple damping structures, such as adding damping oil or springs between transmission components, to mitigate the impact of pressure fluctuations on indicating accuracy. The existing technology has the following drawbacks: the damping structure of existing high-sensitivity industrial pressure gauges is mostly fixed, and its damping characteristics are difficult to adjust flexibly according to the actual pressure change range, vibration frequency and other working conditions. When facing complex and ever-changing industrial environments, it is easy to have problems such as unstable indication, lag in response or oversensitivity. Therefore, an adjustable damping structure and pressure gauge for high-sensitivity industrial pressure gauge are proposed to solve the above problems. Utility Model Content

[0006] As a further description of the above technical solution: The adjustment mechanism includes a compression block, which is slidably connected to the inner wall of the sleeve.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0018] Reference Figures 1-3This utility model provides an embodiment of an adjustable damping structure and pressure gauge for a high-sensitivity industrial pressure gauge. The structure includes a movable plate 3, with a support plate 6 elastically connected to the bottom end of the movable plate 3 via a bellows 4. The bellows 4 itself has a certain elasticity, generating resistance to alleviate some vibration during stretching or compression. A guide tube 5 is fixedly connected to the top end of the support plate 6, ensuring vertical movement of the movable plate 3 without deviation from its trajectory. A mounting tube 7 is fixedly connected to the bottom end of the support plate 6. The surface is threaded, allowing the installation pipe 7 to be connected to an external pipe. Gas from the external pipe can be transmitted to the meter body 1 through the installation pipe 7 and other subsequent components. A sleeve 8 is fixedly connected through the inner wall of the movable plate 3. An adjustment mechanism is provided on the inner wall of the sleeve 8. A piston tube 11 is connected to the inner wall of the sleeve 8. The piston tube 11 can move vertically along the inner wall of the sleeve 8. An air bladder 12 is fixedly connected to the outer wall of the sleeve 8. The air bladder 12 is elastic. When the air bladder 12 expands, its elastic force will continue to increase. When the air bladder 12 is filled with gas or other media and begins to expand, the internal pressure will change accordingly as its volume expands. Its own elastic structure will generate a counteracting elastic force, and this elastic force will continue to increase as the expansion deepens.

[0019] The adjustment mechanism includes a compression block 9, which is slidably connected to the inner wall of the sleeve 8. The contact surface between the compression block 9 and the sleeve 8 is made of rubber material, which can prevent air from being discharged from the compression block 9. The sliding part is sealed. An adjustment screw 16 is rotatably connected to the top of the compression block 9, and the bottom of the compression block 9 is elastically connected to the piston tube 11 through a return spring 10.

[0020] Reference Figures 1-3 The bottom end of the compression block 9 is fixedly connected to one end of the return spring 10. When the compression block 9 moves downward, it will compress the return spring 10. When resetting, the return spring 10 will restore the initial state by its own elasticity. The other end of the return spring 10 is fixedly connected to the top end of the piston tube 11. The adjusting screw 16 passes through and is threadedly connected to the inner wall of the sleeve 8. The middle part of the sleeve 8 is provided with a corresponding threaded groove of the adjusting screw 16, which can satisfy the vertical movement of the adjusting screw 16. A sealing material is provided between the sleeve 8 and the adjusting screw 16 to ensure that the gas will not be discharged through the sleeve 8 and the adjusting screw 16. The piston tube 11 is fixedly connected to the top end of the support plate 6. The guide tube 5 is slidably connected to the outer wall of the movable plate 3. The airbag 12 is connected to the sleeve 8. When in use, air can be allowed to enter the airbag 12 from the sleeve 8, causing the airbag 12 to inflate.

[0021] The bottom end of the movable plate 3 is fixedly connected to one end of the bellows 4. The connection between the bellows 4 and the movable plate 3 and the support plate 6 is sealed to prevent gas from flowing out from the connection. The other end of the bellows 4 is fixedly connected to the top end of the support plate 6. The bellows 4 is connected to the support plate 6 and the movable plate 3 respectively.

[0022] Reference Figure 1 and Figure 4 The watch includes a watch body 1, with a connecting ring 2 fixedly connected to the bottom end of the watch body 1. A semi-circular block 15 is inserted into the outer wall of the connecting ring 2. A groove is formed on the outer wall of the connecting ring 2 to allow the semi-circular block 15 to be inserted into the groove, thus positioning the watch body 1. A fixing plate 13 is elastically connected to the outer wall of the semi-circular block 15 via a positioning spring 14. The outer wall of the semi-circular block 15 is fixedly connected to one end of the positioning spring 14. When the semi-circular block 15 moves forward, it compresses the positioning spring 14. When resetting, the positioning spring... The elastic force of spring 14 causes the semicircular block 15 to return to its original position. The other end of the positioning spring 14 is fixedly connected to the inner wall of the fixed plate 13. The semicircular block 15 is slidably connected to the inner wall of the fixed plate 13. The fixed plate 13 is fixedly connected to the outer wall of the movable plate 3. The fixed plate 13 has a sliding area for the semicircular block 15, which can satisfy the semicircular block 15 sliding along the inner wall of the fixed plate 13. The connecting ring 2 is rotatably connected to the inner wall of the movable plate 3. The connecting ring 2 and the movable plate 3 are connected to each other, which can ensure that gas enters the body 1.

[0023] Working principle: First, to adjust the damping as needed, simply rotate the adjusting screw 16. The adjusting screw 16 will move vertically along the threaded groove of the sleeve 8. The vertical movement of the adjusting screw 16 will cause the compression block 9 to slide up and down synchronously on the inner wall of the sleeve 8. If the adjusting screw 16 causes the compression block 9 to move downward, the compression block 9 will compress the return spring 10; conversely, if it moves upward, it will reset under the elastic force of the return spring 10. The up and down movement of the compression block 9 will change the size of the space it occupies in the sleeve 8. The compressed gas will enter the air bladder 12 from the sleeve 8, and the air bladder 12 will begin to expand. Because it is elastic, as the expansion deepens, the internal pressure changes, and the elastic force it generates will continue to increase. This elastic force acts on the entire structure, and together with the buffer of the bellows 4 and the regulation of the piston tube 11 by the adjusting mechanism, it changes the damping characteristics inside the pressure gauge, thereby achieving sensitive response and damping adjustment to external interferences such as different pressure conditions and different vibration frequencies, so that the pressure gauge can display the pressure value more stably and accurately.

[0024] When it is necessary to adjust the viewing angle of the watch body 1, simply rotate the watch body 1 by hand, causing the connecting ring 2 to rotate. This causes the groove on the outer wall of the connecting ring 2 to press against the semicircular block 15 and compress the positioning spring 14, separating the semicircular block 15 from the groove. When the semicircular block 15 coincides with the groove on the outer wall of the next connecting ring 2, the reverse elastic force of the positioning spring 14 is used to reset the semicircular block 15, allowing it to be inserted into the groove on the outer wall of the connecting ring 2, thus completing the angle positioning of the watch body 1. The operation is simple and convenient.

[0025] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
