Description

Technical Field

[0001] The invention relates to the field of detection and provides a test device for detecting hydrogen-induced pores. Background Art

[0002] Sealing rings play a vital role in various industrial fields, primarily preventing the leakage of fluids and gases and ensuring the performance of sealing systems. Sealing rings can be made from a variety of elastic materials, such as rubber, polyurethane, and silicone. Depending on the application environment, the material selection, structural design, and dimensions of the sealing ring will vary. With the right material and effective sealing force, sealing rings excel in preventing liquid and gas leaks.

[0003] However, when working in special environments such as high-pressure hydrogen, hydrogen-induced porosity (HIPO) in sealing materials becomes a particularly prominent issue. H-induced porosity is formed in sealing materials by hydrogen atoms penetrating into the material. After prolonged exposure, H-induced porosity can lead to localized holes in the material, causing seal failure and posing a safety risk. This requires precise measurement and assessment of H-induced porosity in sealing materials.

[0004] Currently, methods for measuring hydrogen-induced porosity primarily include optical microscopy, scanning electron microscopy (SEM), and X-ray tomography (XCT). While these methods can accurately detect and analyze information such as the size and location of hydrogen-induced porosity, they are relatively costly and susceptible to environmental influences in practice. The measurement cycle is long and may not meet the requirements for rapid response and efficient detection. Therefore, developing an efficient, low-cost method for accurately measuring hydrogen-induced porosity is crucial for improving the performance and safety of sealing materials.

[0030] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention but are not intended to limit the scope of the present invention.

[0031] like Figures 1 to 7 As shown, an embodiment of the present invention provides a test device for hydrogen-induced pore detection, comprising:

[0032] A first housing 100 is provided with a plurality of first radius measuring elements 102, a plurality of first position measuring elements 104, and a plurality of second position measuring elements 110 along the circumference of the first housing 100. The first radius measuring elements 102 are adapted to move in a height direction of the first housing 100, the first position measuring elements 104 are adapted to move in a radial direction of the first housing 100, and the second position measuring elements 110 are adapted to move in a height direction of the first housing 100.

[0033] The second housing 106 is provided with a plurality of second radius measuring members 108 along the circumference of the second housing 106 , and the second radius measuring members 108 are adapted to move along the radial direction of the second housing 106 ;

[0034] When the sample to be tested is placed in the first shell 100 and the second shell 106, the first radius measuring part 102 and the first position measuring part 104 are suitable for being tangent to the bubble edge on the top surface of the sample to be tested, and the second radius measuring part 108 and the second position measuring part 110 are suitable for being tangent to the bubble edge on the side surface of the sample to be tested.

[0035] The embodiment of the present invention provides a detection device for detecting hydrogen-induced pores, which mainly consists of a first shell 100 and a second shell 106. The two shells cooperate with each other in design and function to achieve accurate measurement of hydrogen-induced pores in a sample to be tested.

[0036] A plurality of first radius measuring elements 102, a plurality of first position measuring elements 104, and a plurality of second position measuring elements 110 are arranged along the circumference of the first shell 100. The first radius measuring elements 102 are designed to be able to move along the height direction of the first shell 100, meaning they can move up and down to accommodate cells of different heights. The first position measuring elements 104 can move along the radial direction of the first shell 100, and the second position measuring elements 110 can move along the height direction of the first shell.

[0037] In an embodiment of the present invention, 16 first radius measuring components 102, 16 first position measuring components 104 and 110 can be provided respectively, that is, the angular interval between two adjacent first radius measuring components 102 is 22.5 degrees. Similarly, the angular interval between two adjacent first position measuring components 104 is 22.5 degrees, and the angular interval between two adjacent second position measuring components 110 is 22.5 degrees.

[0038] The first position measuring member 104 can move along the radial direction of the first shell 100 (ie, outward or inward) so as to more accurately locate the position of the cell.

[0039] A plurality of second radius measuring members 108 are provided along the circumference of the second shell 106. Unlike the measuring members in the first shell 100, the second radius measuring members 108 move along the radial direction of the second shell 106, which allows the second radius measuring members 108 to be tangent to the cell edges on the side of the sample to be measured.

[0040] In the embodiment of the present invention, 16 second radius measuring members 108 may be provided, that is, the angular interval between two adjacent second radius measuring members 108 is 22.5 degrees.

[0041] Furthermore, to avoid inconvenience in reading first position measuring device 104 and second position measuring device 110, first position measuring device 104 and second position measuring device 110 are staggered relative to each other. Similarly, first radius measuring device 102 and second radius measuring device 108 are also staggered relative to each other. Furthermore, first position measuring device 104 and first radius measuring device 102 are arranged in the same manner, and second position measuring device 110 and second radius measuring device 108 are arranged in the same manner.

[0042] When the sample to be measured is placed in the first housing 100 and the second housing 106 , the first radius measuring component 102 and the first position measuring component 104 of the first housing 100 will be tangent to the edge of the bubble on the top surface of the sample to be measured.

[0043] At the same time, the second radius measuring component 108 of the second housing 106 and the second position measuring component 110 on the first housing 100 will be tangent to the edge of the bubble on the side of the sample to be measured.

[0044] Specifically, in actual use, the sample to be tested is placed in the first shell 100 and the second shell 106, wherein the first shell 100 corresponds to the top plane of the sample to be tested, and the second shell 106 corresponds to the outer circumferential surface of the bottom cylinder of the sample to be tested.

[0045] When a bubble appears on the top plane of the sample to be tested, it will lift first radius measuring member 102. The radius R1 of the bubble appearing on the top plane can be determined by direct reading or calculation. The end edge of first position measuring member 104 is then brought into contact with the edge of the bubble appearing on the top plane. The distance L1 between the bubble edge and the outer wall of first housing 100 can be read from first position measuring member 104. Since the distance L2 between the center of the top plane and the outer wall of first housing 100 is known, the position of the bubble appearing on the top plane relative to the center of the top plane can be determined by using the formula L2 - L1 - R1.

[0046] When a bubble appears on the side of the sample, it pushes up the second radius measuring member 108, allowing the radius R2 of the bubble to be directly read. The end edge of the second position measuring member 110 is then brought into contact with the edge of the bubble. The distance L3 between the bubble edge and the top plane of the first housing 100 can be read from the second position measuring member 110. Since the distance L4 between the top of the sample and the top of the first housing 100 is known, the distance between the bubble on the side of the sample and the top of the sample can be calculated as L3 - L4 - R2.

[0047] By tangently connecting the first radius measuring member 102, the first position measuring member 104, and the second position measuring member 110 on the first shell 100, and the second radius measuring member 108 on the second shell 106 to the bubble edges of the sample to be tested, precise measurement of the bubble radius and position can be achieved. This design ensures the accuracy and reliability of the measurement. The detection device can simultaneously measure bubbles on the top and side surfaces of the sample to be tested, providing comprehensive bubble detection capabilities. The first radius measuring member 102, the first position measuring member 104, and the second radius measuring member 108 and the second position measuring member 110 can each move in different directions, which increases the flexibility and adaptability of the device, enabling it to handle bubbles of various shapes and sizes. Because the first radius measuring member 102, the first position measuring member 104, the second radius measuring member 108, and the second position measuring member 110 can be tangent to the bubble edges, the measurement process can be greatly simplified and detection efficiency can be improved. The hydrogen-induced bubble detection device provided by the present invention has significant advantages in accuracy, versatility, adaptability and efficiency. Moreover, the detection device realizes the detection of the bubble position and radius on the top and side of the sample to be tested through a purely mechanical structure. The design and maintenance costs are low, providing an effective solution for the detection of hydrogen-induced bubble.

[0048] According to one embodiment of the present invention, a long hole 112 is opened in the side wall of the first shell 100, and the long hole 112 passes through the side wall of the first shell 100 along the radial direction of the first shell 100. Along the circumference of the first shell 100, two opposite side walls of the long hole 112 are opened with a sliding groove 114, and the first radius measuring piece 102 is slidably connected to the sliding groove 114.

[0049] In one embodiment of the present invention, the first housing 100 is a structure having a sidewall with a slot 112 defined therein. This slot 112 extends radially through the sidewall of the first housing 100, extending from one outer surface to the opposite inner surface. Furthermore, slots 114 are defined along the circumference of the first housing 100 (i.e., around the circumference of the housing) on ​​two opposing sidewalls of the slot 112.

[0050] The first radius measuring member 102 is slidably connected to the slide groove 114. This means that the first radius measuring member 102 can slide in a certain direction within the slide groove 114, thereby allowing accurate measurement or adjustment of a certain space or structure within the housing.

[0051] By providing a long hole 112 and a slide groove 114 on the side wall of the shell, and a first radius measuring piece 102 that is slidably connected thereto, the device can flexibly adjust or measure a specific space or structure inside the shell. This design provides greater operating space and convenience. The sliding connection design of the slide groove 114 and the first radius measuring piece 102 helps to achieve high-precision measurement and adjustment. Since the first radius measuring piece 102 can move smoothly in the slide groove 114, its position can be controlled very precisely, thereby ensuring the accuracy of the measurement or adjustment. This design also enhances the adaptability of the device. Different measurement or adjustment requirements can be met by simply sliding the first radius measuring piece 102 without replacing the entire shell or performing complex adjustments. Compared with traditional fixed measurement or adjustment methods, this sliding connection design greatly simplifies the operation process. Users can achieve the required measurement or adjustment by simply sliding the first radius measuring piece 102 without using additional tools or performing complex operations.

[0052] According to one embodiment of the present invention, it further includes a central ring 116 , on which a contact plate 118 is hingedly connected. An end of the contact plate 118 facing away from the central ring 116 is hingedly connected to a translation plate 120 , and the translation plate 120 is slidably connected to the slide groove 114 .

[0053] In one embodiment of the present invention, a central ring 116 and its associated contact plate 118 and translation plate 120 are newly added to further enhance the accuracy and flexibility of measurement and adjustment.

[0054] The center ring 116 is located inside the first shell 100 . The center ring 116 serves as the central support point of the entire new structure, providing a stable connection foundation for the subsequent contact plate 118 and translation plate 120 .

[0055] One end of the contact plate 118 is connected to the central ring 116 in a hinged manner, so that the contact plate 118 can rotate around a certain axis.

[0056] One end of the translation plate 120 is hinged to the end of the contact plate 118 facing away from the center ring 116, and the other end is slidably connected to the aforementioned slide 114. This design allows the translation plate 120 to rotate around the hinge point between the contact plate 118 and the center ring 116, and to translate along the slide 114.

[0057] By introducing the structure of the center ring 116, contact plate 118, and translation plate 120, this embodiment further enhances the flexibility of the device. The contact plate 118 and translation plate 120 can move around the center ring 116 and along the slide 114, respectively, enabling more diverse measurement and adjustment methods. Because the contact plate 118 and translation plate 120 can rotate and translate independently, the contact point with the sample to be measured or other structures within the housing can be more accurately located and adjusted. This design helps reduce errors and improve measurement accuracy. The introduction of this new structure makes the operation process smoother and more efficient. Users can quickly achieve the required measurement or adjustment by adjusting the position and angle of the contact plate 118 and translation plate 120 without complicated operations or adjustments. This design also enhances the adaptability of the device. Whether facing samples of different shapes, sizes, or positions, or facing different structures within the housing, the device can meet the requirements by adjusting the position and angle of the contact plate 118 and translation plate 120.

[0058] According to one embodiment of the present invention, along the height direction of the first shell 100, a first opening 122 connecting the long hole 112 is opened on the first shell 100, and the first radius measuring piece 102 is inserted into the first opening 122. One end of the first radius measuring piece 102 inserted into the first opening 122 is connected to the translation plate 120.

[0059] In one embodiment of the present invention, to further enhance the practicality of the structure and the flexibility of measurement and adjustment, additional design improvements have been made to the first housing 100. Specifically, a first opening 122, communicating with the elongated hole 112, is provided on the sidewall of the first housing 100 along its height (i.e., perpendicular to its bottom surface). This design of first opening 122 allows the first radius measuring member 102 to not only slide within the guide slot 114 but also be inserted through the first opening 122 from outside the housing and connected to the translation plate 120.

[0060] First opening 122 is located on the side wall of first housing 100. It extends along the height of the housing and communicates with the aforementioned elongated hole 112. This design allows first radius measuring member 102 to be easily inserted into elongated hole 112 and slot 114 from outside the housing, eliminating the need for complex internal assembly.

[0061] One end of the first radius measuring member 102 is designed to be inserted into the first opening 122. Once inserted, it is connected to the translating plate 120. This connection can be direct (e.g., via fasteners such as bolts and pins) or indirect (e.g., via a connector or intermediate member). Either method ensures that the first radius measuring member 102 is stably and securely connected to the translating plate 120, enabling precise measurement and adjustment.

[0062] By introducing the design of the first opening 122, the user can easily insert and connect the first radius measuring piece 102 to the translation plate 120 from the outside of the shell, which greatly improves the practicality and ease of use of the device. The design of the first opening 122 allows the first radius measuring piece 102 to be moved and adjusted in multiple directions, including sliding along the slide groove 114 and inserting / extracting in the height direction. This multi-dimensional adjustment capability enables the device to adapt to more diverse measurement and adjustment needs. Compared with the traditional internal assembly method, the design of inserting the first radius measuring piece 102 from the outside through the first opening 122 and connecting it to the translation plate 120 greatly simplifies the assembly process. This not only saves time and cost, but also reduces the error rate during the assembly process. Since the first radius measuring piece 102 can be smoothly and firmly connected to the translation plate 120, it can ensure higher accuracy and stability during the measurement and adjustment process.

[0063] According to one embodiment of the present invention, the sliding groove 114 is arc-shaped so as to enable the translation plate 120 to move along the height direction of the first housing 100 .

[0064] In one embodiment of the present invention, the slide groove 114 is designed to be arc-shaped. This design is intended to change the motion trajectory of the translation plate 120 so that it can only move along the height direction of the first housing 100. This change not only enhances the functionality of the device, but also improves its measurement accuracy and adjustment flexibility.

[0065] The conventional chute 114 is usually linear, while the chute 114 in this embodiment is designed to be arc-shaped. This design enables the translation plate 120 to move along a curved track when sliding along the chute 114, rather than a simple linear motion.

[0066] Because the translation plate 120 is connected to the contact plate 118, and the length of the contact plate 118 is fixed, when bubbles appear on the top surface of the sample to be tested, the contact plate 118 is lifted, resulting in an arc-shaped motion trajectory of the translation plate 120. The arc-shaped chute 114 allows the translation plate 120 to naturally move along the height direction of the first housing 100 as it slides along the chute 114. This change in motion trajectory allows the translation plate 120 to more accurately locate and adjust the contact point with the sample to be tested or other structures within the housing. The design of the arc-shaped chute 114 greatly enhances the flexibility of measurement and adjustment.

[0067] By adjusting the position of the translating plate 120 within the curved slot 114, users can quickly perform desired measurements or adjustments without the need for complex manipulation or adjustments. The curved slot 114 allows the translating plate 120 to more precisely move along the height of the first housing 100, thereby improving measurement accuracy. This design helps reduce errors and enhances measurement accuracy. Because the translating plate 120 can move along the curved slot 114, the device can more flexibly adapt to the needs of test samples of varying shapes, sizes, and positions, or other structures within the housing. The curved slot 114 design makes operation smoother and more efficient. Users can quickly perform desired measurements or adjustments by simply adjusting the position of the translating plate 120 within the curved slot 114, without the need for complex manipulation or adjustments. This design not only enhances the device's practicality and flexibility, but also provides users with a more convenient and efficient measurement and adjustment experience. Users can more easily complete measurement and adjustment tasks, thereby improving work efficiency and satisfaction.

[0068] In the embodiment of the present invention, since the contact plate 118 and the translation plate 120 are introduced, the radius of the bubble on the top plane of the sample to be tested can be calculated as follows:

[0069]

[0070] Among them, the reading of the first radius measuring component 102 is h, the reading of the first position measuring component 104 is L5, the length of the contact plate 118 is L6, the radius of the bubble at the top of the sample to be measured is R, the distance between the bubble at the top of the sample to be measured and the center of the top plane of the sample to be measured is Y, and the angle between the contact plate 118 and the top plane of the sample to be measured is θ.

[0071] According to one embodiment of the present invention, a guide groove 124 is defined on a side wall of the long hole 112 facing the second housing 106 , and the first position measuring member 104 is slidably connected to the guide groove 124 .

[0072] In one embodiment of the present invention, the elongated hole 112 is not only connected to the slide slot 114, but also has an additional guide slot 124 formed on the side wall thereof facing the second housing 106. This design allows the first position measuring member 104 to slide within the guide slot 124, thereby enabling precise measurement of specific positions inside or outside the housing.

[0073] The guide groove 124 is opened along the side wall of the long hole 112 toward the second housing 106 . The design of the guide groove 124 allows the first position measuring member 104 to slide therein, thereby achieving accurate measurement of a specific position inside or outside the housing.

[0074] The first position measuring member 104 is designed to be slidably connected to the guide groove 124. This connection can be direct (e.g., via a slide rail, slider, etc.) or indirect (e.g., via a connector or intermediate member). Either method ensures that the first position measuring member 104 can slide smoothly and securely within the guide groove 124.

[0075] By introducing the design of the guide groove 124 and the first position measuring member 104, the present invention adds a new measurement dimension. This enables the device to more comprehensively measure the spatial dimensions and positional relationships of specific positions inside or outside the shell. Since the first position measuring member 104 can slide smoothly and firmly in the guide groove 124, higher accuracy and stability can be ensured during the measurement process. This design helps to reduce errors and improve the accuracy of measurements. The design of the guide groove 124 and the first position measuring member 104 makes the measurement process more flexible and efficient. Users can quickly achieve the required measurement by adjusting the position of the first position measuring member 104 in the guide groove 124 without the need for complicated operations or adjustments. This design not only improves the measurement capability of the device, but also adds more functionality to it. For example, by combining the use of the slide groove 114 and the guide groove 124, the device can achieve accurate measurement and adjustment of multiple positions inside or outside the shell.

[0076] According to one embodiment of the present invention, a second opening 126 is formed on the first housing 100 along a height direction of the first housing 100 , and the second position measuring component 110 is inserted into the second opening 126 .

[0077] In one embodiment of the present invention, to further enhance the measurement functionality and flexibility of the device, a second opening 126 is provided along the height of the first housing 100. This second opening 126 allows the second position measurement device 110 to be inserted from outside the housing into the housing, thereby enabling precise measurement of the interior of the housing or associated structures.

[0078] The second opening 126 is an opening located in a side wall or top / bottom of the first housing 100 and extends along the height of the housing. The design of the second opening 126 allows the second position measuring device 110 to be easily inserted into the housing from outside without requiring complex internal assembly.

[0079] The second position measuring member 110 is designed to be inserted into the second opening 126. Once inserted, it can contact the interior of the housing or associated structures to achieve accurate measurement. This contact can be direct (e.g., through contact between the distal end of the measuring member and the surface to be measured) or indirect (e.g., through a measuring probe or sensor).

[0080] By introducing the design of the second opening 126 and the second position measuring member 110, the present invention further enhances the measuring function of the device. The user can use the second position measuring member 110 to accurately measure the interior of the shell or the structures associated therewith, thereby obtaining more comprehensive size and position information. The design of the second opening 126 allows the second position measuring member 110 to be inserted and removed from the outside of the shell, which enables the device to adapt more flexibly to different measurement needs. Users can choose measuring members of different sizes or types as needed to meet specific measurement requirements. Compared with traditional internal measurement methods, the design of inserting the second position measuring member 110 from the outside through the second opening 126 greatly simplifies the measurement process. This not only saves time and cost, but also reduces the error rate during the measurement process. This design not only improves the measurement accuracy and flexibility of the device, but also provides users with a more convenient and efficient measurement experience. Users can complete measurement tasks more easily, thereby improving work efficiency and satisfaction.

[0081] According to one embodiment of the present invention, a mounting hole 128 is defined in the side wall of the second housing 106 , and the second radius measuring member 108 is inserted into the mounting hole 128 .

[0082] In one embodiment of the present invention, a mounting hole 128 is provided on the side wall of the second shell 106. The design of the mounting hole 128 allows the second radius measuring member 108 to be inserted from the outside of the shell into the interior of the shell or into a structure associated therewith, thereby achieving accurate measurement of these structures.

[0083] Mounting hole 128 is located on the sidewall of second housing 106. Its location and dimensions are precisely designed to ensure smooth and secure insertion of second radius measuring element 108. This mounting hole 128 not only provides a convenient insertion channel for the measuring element, but also ensures stability and accuracy during the measurement process.

[0084] The second radius measuring member 108 is designed to be inserted into the mounting hole 128 and, once inserted, can make contact with the interior of the housing or associated structures to achieve accurate radius measurement. This contact can be direct (e.g., by the distal end of the measuring member making contact with the surface to be measured) or indirect (e.g., via a measuring probe or sensor).

[0085] By introducing the design of the mounting hole 128 and the second radius measuring piece 108, the present invention can achieve accurate radius measurement of the interior of the shell or the structure associated with it. This design helps to reduce errors and improve the accuracy of measurements. The design of the mounting hole 128 allows the second radius measuring piece 108 to be inserted and removed from the outside of the shell, which enables the device to adapt more flexibly to different measurement needs. Users can choose measuring pieces of different sizes or types as needed to meet specific measurement requirements. Compared with traditional internal measurement methods, the design of inserting the second radius measuring piece 108 from the outside through the mounting hole 128 greatly simplifies the measurement process. Users can easily complete the measurement task without disassembling the shell or performing complex internal assembly. This design not only improves the measurement accuracy and flexibility of the device, but also provides users with a more convenient and efficient measurement experience. Users can complete measurement tasks more easily, thereby improving work efficiency and satisfaction.

[0086] According to one embodiment of the present invention, two groups of mounting holes 128 are provided along the height direction of the second shell 106 , and a second radius measuring piece 108 is inserted into each group of mounting holes 128 . The end of the second radius measuring piece 108 facing the interior of the second shell 106 is connected to a synchronization rod 130 .

[0087] In one embodiment of the present invention, two sets of mounting holes 128 are provided along the height of the sidewall of the second housing 106. A second radius measuring member 108 is inserted into each set of mounting holes 128, and each end of these measuring members, facing the interior of the second housing 106, is connected to a synchronization rod 130. This design is intended to improve measurement accuracy and efficiency while enhancing the flexibility and practicality of the device.

[0088] Two sets of mounting holes 128 are provided along the height direction on the side wall of the second housing 106, and each set of mounting holes 128 is located at a different height position. This design allows the user to measure the radius at different height positions, thereby obtaining more comprehensive dimensional information.

[0089] A second radius measuring member 108 is inserted into each set of mounting holes 128. These measuring members can slide or adjust along the direction of the mounting holes 128 to meet different measurement requirements, while also improving the movement stability of the second radius measuring member 108.

[0090] Each second radius measuring member 108 is connected to a synchronization rod 130 at one end facing the interior of the second housing 106. These synchronization rods 130 maintain synchronized movement between the upper and lower second radius measuring members 108 during the measurement process, thereby ensuring accurate and consistent measurements. Through the synchronization rods 130, when one second radius measuring member 108 moves, the other second radius measuring member 108 also moves accordingly, maintaining their relative position.

[0091] By introducing the design of the synchronization rod 130, the present invention can ensure the synchronous movement of the two second radius measuring parts 108 during the measurement process, thereby greatly improving the accuracy of the measurement. This design helps to reduce errors and improve the reliability of the measurement. Due to the provision of two sets of mounting holes 128 and two second radius measuring parts 108, users can perform simultaneous measurements at different height positions, thereby greatly improving measurement efficiency. This design allows users to obtain the required dimensional information more quickly, thereby improving work efficiency. Compared with traditional single-point measurement methods, the present invention achieves multi-point synchronous measurement by introducing the design of two sets of mounting holes 128 and the synchronization rod 130. This not only simplifies the measurement process, but also reduces the complexity and error rate during the measurement process. This design not only improves the measurement accuracy and efficiency of the device, but also provides users with a more convenient and efficient measurement experience. Users can complete measurement tasks more easily and obtain more comprehensive dimensional information, thereby improving work satisfaction and efficiency.

[0092] According to one embodiment of the present invention, a third radius measuring member 134 is provided at the center of the first shell 100 . A bracket 132 is connected to the first shell 100 , and the third radius measuring member 134 is movably inserted into the bracket 132 .

[0093] In one embodiment of the present invention, a bracket 132 for mounting a third radius measuring member 134 is provided at the center of the first housing 100. The bracket 132 not only allows the third radius measuring member 134 to accurately measure the radius at the center of the first housing 100, but also enables the third radius measuring member 134 to be flexibly moved and adjusted.

[0094] The center of the first housing 100 is designed to accommodate and mount a bracket 132, which is used to mount and support a third radius measuring device 134. The third radius measuring device 134 is specifically designed to accurately measure the radius of the bubble at the center of the top of the sample to be measured, and its size and shape match the center of the first housing 100.

[0095] To enhance the flexibility and practicality of the third radius measuring member 134, a bracket 132 is attached to the first housing 100. This bracket 132 is designed to firmly support the third radius measuring member 134 and allow it to move within a certain range on the bracket 132. This design allows the user to adjust the position and angle of the third radius measuring member 134 as needed to accommodate different measurement requirements.

[0096] The third radius measuring member 134 is designed to be movably inserted into the bracket 132. This means that the third radius measuring member 134 can not only translate on the bracket 132, but also rotate and tilt. This mobility allows the third radius measuring member 134 to more flexibly adapt to different measurement scenarios and objects. During actual testing, the radius of the bubble at the center of the top plane of the sample under test can be measured directly.

[0097] By arranging the third radius measuring piece 134 at the center of the first shell 100 and connecting it to a stable bracket 132, the present invention can ensure stability and accuracy during the measurement process. This design helps to reduce errors and improve the reliability of the measurement. The movable design of the bracket 132 and the third radius measuring piece 134 allows the user to adjust the position and angle of the measuring piece as needed. This flexibility not only improves the efficiency of the measurement, but also enables the device to be more widely used in different measurement scenarios and objects. Compared with the traditional fixed measurement method, the present invention optimizes the measurement process by introducing the movable design of the bracket 132 and the third radius measuring piece 134. Users can complete measurement tasks more easily and obtain more accurate measurement results.
