Description

Technical Field

[0001] This utility model relates to the field of digital pressure gauge technology, and more specifically, to a rotary display mechanism for digital pressure gauges. Background Technology

[0002] Digital pressure gauges have been widely used in many fields such as industrial production, construction, and pipeline inspection due to their advantages such as intuitive readings, high accuracy, and easy data transmission. However, existing digital pressure gauges have many inconveniences in actual use.

[0003] Due to the diversity and complexity of installation locations, such as pipe bends and narrow spaces within equipment, the gauge head of a digital pressure gauge is often not at an easily observable angle. Traditional digital pressure gauges are mostly fixed in place, requiring users to adjust their position or even use auxiliary tools to read pressure values, which is very inconvenient. This not only reduces work efficiency but also easily leads to reading errors due to improper observation angles. Therefore, a rotating display mechanism for digital pressure gauges is proposed. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a digital pressure gauge rotary display mechanism to solve the problems mentioned in the background art.

[0006] A guide tube is fixedly connected to the inner cavity of the sealing groove. The outer surface of the insertion tube is provided with toothed grooves. A fixing block is fixedly connected to one side of the insertion tube. A limit groove is provided at the bottom of the inner cavity of the fixing tube corresponding to the position of the fixing block. The cooperation between the fixing block and the limit groove can limit the rotation angle of the meter head. A sealing tube is fixedly connected to the top of the inner cavity of the fixing tube. The sealing tube is inserted into the sealing groove and, together with the guide tube, forms a good sealing structure. On the one hand, it prevents external dust, moisture and other impurities from entering the inside of the meter head and protects the internal electronic components. On the other hand, it avoids gas or liquid leakage during pressure measurement and ensures the accuracy and stability of the measurement data.

[0007] A threaded rod is inserted into one side of the fixed tube. One end of the threaded rod is rotatably connected to a moving plate, and the other end of the threaded rod is fixedly connected to a turntable. A pressing plate is provided on one side of the moving plate, and a spring is provided between the moving plate and the pressing plate. Teeth are fixedly connected to one side of the pressing plate. By pushing the pressing plate with the spring, the teeth mesh with the tooth groove, which can fix the angle of the meter head. By forcefully rotating the meter head, the tooth groove and teeth can be misaligned to make the pressing plate press against the spring, which can easily adjust the angle of the meter head and automatically fix it. When the spring elasticity decreases, the threaded rod can be rotated to move the moving plate to press against the spring, restoring the spring's pushing strength against the pressing plate and improving the performance.

[0008] Preferably, the sealing tube is adapted to the sealing groove, one end of the guide tube extends into the interior of the sealing tube, and one end of the sealing tube extends into the interior of the sealing groove. The sealing tube is inserted into the sealing groove and, together with the guide tube, forms a good sealing structure. On the one hand, it prevents external dust, moisture and other impurities from entering the inside of the meter head and protects the internal electronic components. On the other hand, it avoids gas or liquid leakage during pressure measurement and ensures the accuracy and stability of the measurement data.

[0009] Preferably, the limiting plate is located at the bottom of the fixed tube, and the inner cavity of the threaded tube is connected to the inner cavity of the guide tube through the threaded head and the insert tube. By connecting the threaded tube, it can be used to connect the pressure measuring pipeline to realize the transmission and measurement of pressure and ensure the normal operation of the gauge.

[0010] Preferably, a limiting block is fixedly connected to one side of the inner cavity of the limiting groove. The limiting block is adapted to the limiting groove and is located in the middle of the limiting groove. The limiting block limits the rotation angle of the fixed block, thereby limiting the rotation angle of the meter head.

[0011] Preferably, the tooth groove corresponds to the extrusion plate, the tooth groove is configured as an annular structure, and the teeth mesh with the wall of the tooth groove. The rotation angle of the dial indicator can be fixed by the meshing of the teeth and the tooth groove.

[0012] Preferably, the threaded rod is threadedly connected to the wall of the fixed tube, and stabilizing grooves are provided on both the upper and lower sides of the moving plate and the extrusion plate.

[0013] Preferably, a stabilizing strip is fixedly connected to the inner cavity of the fixed tube at a position corresponding to the stabilizing groove. The stabilizing strip is located in the middle of the stabilizing groove. The stability of the moving plate and the extrusion plate is improved by the cooperation of the stabilizing groove and the stabilizing strip.

[0014] The technical effects and advantages of this utility model are as follows:

[0015] 1. This utility model firstly involves rotating the gauge head to compress the toothed groove against the extrusion plate, thereby compressing the spring. This continues until the teeth on one side of the extrusion plate mesh with the teeth on the other side of the toothed groove, allowing for angle adjustment of the gauge head's display orientation. This facilitates easy reading of pressure values ​​in various complex installation environments, improving ease of use and flexibility. Furthermore, the cooperation between the sealing groove and the guide tube with the sealing tube effectively prevents external impurities from entering and internal media from leaking, protecting the internal components of the digital pressure gauge, ensuring the accuracy of measurement data, and extending the equipment's service life.

[0016] 2. This utility model also limits the rotation angle of the digital pressure gauge by setting a fixed block and a limiting groove, avoiding excessive twisting and pulling of the internal connecting lines during the rotation of the gauge head, reducing the risk of line damage, lowering the equipment failure rate and maintenance costs, and adjusting the pushing strength of the spring on the pressing plate by rotating the turntable to control the moving plate, thereby increasing the resistance strength of the gauge head rotation and facilitating adjustment and use.

[0017] In summary, through the interaction of the above-mentioned functions, the angle of the meter display can be easily adjusted, allowing users to easily read pressure values ​​in various complex installation environments, thus improving the convenience and flexibility of use.

The cooperation between the fixing block 10 and the limiting groove 11 can limit the rotation angle of the meter head 1. A sealing tube 20 is fixedly connected to the top of the inner cavity of the fixing tube 2. The sealing tube 20 is inserted into the sealing groove 7 and, together with the guide tube 8, forms a good sealing structure. On the one hand, it prevents external dust, moisture and other impurities from entering the inside of the meter head 1 and protects the internal electronic components. On the other hand, it avoids gas or liquid leakage during pressure measurement and ensures the accuracy and stability of the measurement data.

[0027] A threaded rod 12 is inserted into one side of the fixed tube 2. One end of the threaded rod 12 is rotatably connected to a movable plate 14, and the other end of the threaded rod 12 is fixedly connected to a turntable 13. A pressing plate 15 is provided on one side of the movable plate 14, and a spring 17 is provided between the movable plate 14 and the pressing plate 15. A tooth 16 is fixedly connected to one side of the pressing plate 15. By pushing the pressing plate 15 with the spring 17, the tooth 16 meshes with the tooth groove 9, which can fix the angle of the meter head 1. By forcefully rotating the meter head 1, the tooth groove 9 and the tooth 16 can be misaligned, causing the pressing plate 15 to press against the spring 17. This allows for easy adjustment of the angle of the meter head 1 and automatic fixing. When the elasticity of the spring 17 decreases, the threaded rod 12 can be rotated to press the spring 17 with the movable plate 14, restoring the pushing strength of the spring 17 against the pressing plate 15 and improving the performance.

[0028] As attached Figure 1-5As shown, the sealing tube 20 is adapted to the sealing groove 7. One end of the guide tube 8 extends into the interior of the sealing tube 20, and the other end of the sealing tube 20 extends into the interior of the sealing groove 7.

On the other hand, it avoids gas or liquid leakage during pressure measurement and ensures the accuracy and stability of the measurement data. The connecting threaded tube 6 can be used to connect the pressure measurement pipeline to realize the transmission and measurement of pressure and ensure the normal operation of the gauge head 1. The rotation angle of the fixed block 10 is limited by the limiting block, thereby limiting the rotation angle of the gauge head 1. The rotation angle of the gauge head 1 can be fixed by the meshing of the teeth 16 and the tooth groove 9. The cooperation of the stabilizing groove 18 and the stabilizing strip 19 improves the stability of the movement of the moving plate 14 and the squeezing plate 15.

[0029] The working principle of this utility model is as follows: When it is necessary to adjust the display angle of the meter head 1, the meter head 1 is rotated directly to make the tooth groove 9 press against the pressing plate 15, so that the pressing plate 15 presses against the spring 17 until the teeth on one side of the pressing plate 15 mesh with the other side of the tooth groove 9, and the angle of the display orientation of the meter head 1 can be adjusted.

[0030] When the spring force of spring 17 decreases, the moving plate 14 can be controlled by rotating the turntable 13 to compress the spring 17, thereby restoring the pushing force of spring 17 on the compression plate 15, increasing the strength of fixing the angle of the meter head 1, and improving the performance.
