Description

Technical Field

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

[0002] Sealing rings play a vital role in various industrial fields. Their main function is to prevent the leakage of fluids or gases and ensure the performance of the sealing system. Sealing rings can be made of a variety of elastic materials such as rubber, polyurethane, silicone, etc. Depending on the application environment, the material selection, structural design and size specifications of the sealing ring will also vary. With the right materials and effective sealing force, sealing rings perform well in preventing the leakage of liquids and gases.

[0003] However, when it comes to special working environments such as high-pressure hydrogen, the problem of hydrogen-induced pores in sealing materials becomes particularly prominent. Hydrogen-induced pores in sealing materials are formed after long-term exposure when hydrogen atoms penetrate into the material. They can cause local holes in the material, thereby causing sealing failure and posing certain safety risks. This requires accurate measurement and evaluation of hydrogen-induced pores in sealing materials.

[0004] At present, the methods for measuring hydrogen-induced pores mainly include optical microscopy, scanning electron microscopy (SEM) and X-ray tomography (XCT). Although these methods can accurately detect and analyze the size, location and other information of hydrogen-induced pores, in practical applications, the cost is relatively high and they are easily affected by external environmental factors. The measurement cycle is long and may not meet the needs of rapid response and efficient detection. Therefore, developing an efficient, low-cost method that can accurately measure hydrogen-induced pores is of great significance for improving the performance and safety of sealing materials.

DETAILED DESCRIPTION

[0026] The following embodiments of the present invention are described in further detail in conjunction with 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.

[0027] like Figures 1 to 7 As shown, an embodiment of the present invention provides a test device for hydrogen-induced pore detection, comprising: A first shell 100, wherein a plurality of first radius measuring members 102, a plurality of first position measuring members 104 and a plurality of second position measuring members 110 are disposed on the first shell 100 along the circumference of the first shell 100, wherein the first radius measuring members 102 are adapted to move along the height direction of the first shell 100, the first position measuring members 104 are adapted to move along the radial direction of the first shell 100, and the second position measuring members 110 are adapted to move along the height direction of the first shell 100; A second shell 106 , wherein a plurality of second radius measuring members 108 are disposed on the second shell 106 along the circumference of the second shell 106 , and the second radius measuring members 108 are adapted to move along the radial direction of the second shell 106 ; When the sample to be tested is placed in the first shell 100 and the second shell 106, the first radius measuring piece 102 and the first position measuring piece 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 piece 108 and the second position measuring piece 110 are suitable for being tangent to the bubble edge on the side surface of the sample to be tested.

[0028] 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.

[0029] A plurality of first radius measuring members 102, a plurality of first position measuring members 104 and a plurality of second position measuring members 110 are arranged along the circumference of the first shell 100. The first radius measuring members 102 are designed to be able to move along the height direction of the first shell 100, which means that they can move up and down to adapt to cells of different heights, the first position measuring members 104 can move along the radial direction of the first shell 100, and the second position measuring members 110 can move along the height direction of the first shell.

[0030] 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, and 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.

[0031] 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.

[0032] A plurality of second radius measuring pieces 108 are arranged along the circumference of the second shell 106. Different from the measuring pieces in the first shell 100, the second radius measuring pieces 108 move along the radial direction of the second shell 106, which allows the second radius measuring pieces 108 to be tangent to the cell edge on the side of the sample to be tested.

[0033] 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.

[0034] In addition, in order to avoid inconvenience in reading the first position measuring member 104 and the second position measuring member 110, the first position measuring member 104 and the second position measuring member 110 are mutually staggered, and similarly, the first radius measuring member 102 and the second radius measuring member 108 are also mutually staggered. Moreover, the first position measuring member 104 and the first radius measuring member 102 are arranged in the same manner, and the second position measuring member 110 and the second radius measuring member 108 are arranged in the same manner.

[0035] When the sample to be tested is placed in the first shell 100 and the second shell 106 , the first radius measuring component 102 and the first position measuring component 104 of the first shell 100 will be tangent to the edge of the bubble on the top surface of the sample to be tested.

[0036] At the same time, the second radius measuring member 108 of the second housing 106 and the second position measuring member 110 on the first housing 100 will be tangent to the edge of the bubble on the side of the sample to be measured.

[0037] 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.

[0038] When bubbles appear on the top plane of the sample to be tested, the bubbles appearing on the top plane will lift up the first radius measuring piece 102, and the radius R1 of the bubbles appearing on the top plane can be obtained by direct reading or calculation. Then the end edge of the first position measuring piece 104 is brought into contact with the edge of the bubble appearing on the top plane, and the distance L1 between the bubble edge and the outer wall of the first shell 100 can be read out by the reading of the first position measuring piece 104. Since the distance L2 between the center of the top plane and the outer wall of the first shell 100 is known data, the position of the bubble appearing on the top plane relative to the center of the top plane can be obtained by using L2-L1-R1.

[0039] When bubbles appear on the side of the sample to be tested, the bubbles appearing on the side will lift up the second radius measuring member 108, and the radius R2 of the bubbles appearing on the side can be obtained by direct reading. Then the end edge of the second position measuring member 110 is brought into contact with the edge of the bubble appearing on the side, and the distance L3 between the bubble edge and the top plane of the first shell 100 can be read out by the reading of the second position measuring member 110. Since the distance L4 between the top of the sample to be tested and the top of the first shell 100 is known data, the distance between the bubble on the side of the sample to be tested and the top of the sample to be tested can be obtained by L3-L4-R2.

[0040] The first radius measuring member 102, the first position measuring member 104, the second position measuring member 110 on the first shell 100 and the second radius measuring member 108 on the second shell 106 are tangent to the bubble edge of the sample to be tested, so that the radius and position of the bubble can be accurately measured. This design ensures the accuracy and reliability of the measurement. The detection device can simultaneously measure the bubbles on the top and side surfaces of the sample to be tested, providing a comprehensive bubble detection capability. The first radius measuring member 102 and the first position measuring member 104 and the second radius measuring member 108 and the second position measuring member 110 can move in different directions, which increases the flexibility and adaptability of the device, so that it can handle bubbles of various shapes and sizes. Since 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 be tangent to the bubble edge, the measurement process can be greatly simplified and the 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 of the top and side of the sample to be tested through a purely mechanical structure. The design and maintenance costs are low, and an effective solution is provided for the detection of hydrogen-induced bubble.

[0041] 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 penetrates 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.

[0042] In one embodiment of the present invention, the first housing 100 is a structure having a side wall, and a long hole 112 is formed on the side wall. The long hole 112 penetrates the side wall along the radial direction of the first housing 100, which means that it extends from an outer surface to an opposite inner surface. In addition, along the circumference of the first housing 100 (i.e., the circumferential direction around the housing), a slide groove 114 is further formed on two opposite side walls of the long hole 112.

[0043] The first radius measuring member 102 is slidably connected to the slide slot 114. This means that the first radius measuring member 102 can slide in a certain direction in the slide slot 114, thereby allowing accurate measurement or adjustment of a certain space or structure in the housing.

[0044] 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 slidably connected thereto, the device can flexibly adjust or measure a specific space or structure inside the shell. This design provides a larger 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 accurately to ensure 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 the traditional fixed measurement or adjustment method, this sliding connection design greatly simplifies the operation process. The user can achieve the required measurement or adjustment by simply sliding the first radius measuring piece 102 without using additional tools or performing complex operations.

[0045] According to an embodiment of the present invention, it further includes a central ring 116 , on which a contact plate 118 is hingedly connected, and 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 slot 114 .

[0046] In one embodiment of the present invention, a central ring 116 and a contact plate 118 and a translation plate 120 structure associated therewith are newly added to further improve the accuracy and flexibility of measurement and adjustment.

[0047] The center ring 116 is located inside the first shell 100 . The center ring 116 serves as a central support point of the entire new structure, providing a stable connection foundation for the subsequent contact plate 118 and the translation plate 120 .

[0048] 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.

[0049] One end of the translation plate 120 is hinged to the end of the contact plate 118 away from the center ring 116, and the other end is slidably connected to the aforementioned slide slot 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 slot 114.

[0050] By introducing the structure of the center ring 116, the contact plate 118 and the translation plate 120, the present embodiment further improves the flexibility of the device. The contact plate 118 and the translation plate 120 can move around the center ring 116 and along the slide groove 114, respectively, thereby realizing more diverse measurement and adjustment methods. Since the contact plate 118 and the translation plate 120 can respectively perform rotation and translation movements, the contact points with the sample to be measured or other structures in the shell can be more accurately located and adjusted. This design helps to reduce errors and improve the accuracy of measurement. The introduction of the new structure makes the operation process smoother and more efficient. The user can quickly achieve the required measurement or adjustment by adjusting the position and angle of the contact plate 118 and the translation plate 120 without complicated operations or adjustments. This design also enhances the adaptability of the device. Whether facing samples to be measured of different shapes, sizes or positions, or facing the needs of different structures in the shell, the device can meet the requirements by adjusting the position and angle of the contact plate 118 and the translation plate 120.

[0051] 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.

[0052] In one embodiment of the present invention, in order to further enhance the practicality of the structure and the flexibility of measurement and adjustment, additional design improvements are made to the first housing 100. Specifically, along the height direction of the first housing 100 (i.e., perpendicular to the bottom surface of the housing), a first opening 122 connected to the long hole 112 is opened on the side wall of the first housing 100. The design of this first opening 122 allows the first radius measuring member 102 to not only slide in the slide groove 114, but also be inserted through the first opening 122 from the outside of the housing and connected to the translation plate 120.

[0053] The first opening 122 is an opening on the side wall of the first housing 100, which extends along the height direction of the housing and is connected to the aforementioned long hole 112. This design allows the first radius measuring member 102 to be easily inserted into the long hole 112 and the slide groove 114 from the outside of the housing without complicated internal assembly.

[0054] One end of the first radius measuring member 102 is designed to be inserted into the first opening 122, and once inserted, it is connected to the translation plate 120. This connection can be direct (for example, through fasteners such as bolts and pins) or indirect (for example, through some kind of connecting member or intermediate member). In either case, it is ensured that the first radius measuring member 102 can be stably and firmly connected to the translation plate 120, thereby achieving accurate measurement and adjustment.

[0055] 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 / pulling out 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.

[0056] According to an embodiment of the present invention, the slide groove 114 is arc-shaped so as to enable the translation plate 120 to move along the height direction of the first housing 100 .

[0057] In one embodiment of the present invention, the slide slot 114 is designed to be arc-shaped, which is intended to change the movement 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.

[0058] The conventional slide groove 114 is usually linear, while the slide groove 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 slide groove 114, rather than a simple linear motion.

[0059] Since 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 plane of the sample to be tested, the contact plate 118 is lifted up, so the movement trajectory of the translation plate 120 is arc-shaped, and the slide groove 114 is set in an arc shape, so that when the translation plate 120 slides along the slide groove 114, it will naturally move along the height direction of the first shell 100. This change in the movement trajectory enables the translation plate 120 to more accurately locate and adjust the contact point with the sample to be tested or other structures in the shell. The design of the arc-shaped slide groove 114 greatly enhances the flexibility of measurement and adjustment.

[0060] The user can quickly achieve the required measurement or adjustment by adjusting the position of the translation plate 120 in the arc-shaped slide groove 114 without complicated operations or adjustments. The design of the arc-shaped slide groove 114 enables the translation plate 120 to move more accurately along the height direction of the first shell 100, thereby improving the accuracy of the measurement. This design helps to reduce errors and improve the accuracy of the measurement. Since the translation plate 120 can move along the arc-shaped slide groove 114, the device can more flexibly adapt to the needs of samples to be tested or other structures in the shell of different shapes, sizes or positions. The design of the arc-shaped slide groove 114 makes the operation process smoother and more efficient. The user can quickly achieve the required measurement or adjustment by simply adjusting the position of the translation plate 120 in the arc-shaped slide groove 114 without complicated operations or adjustments. This design not only improves the practicality and flexibility of the device, but also provides users with a more convenient and efficient measurement and adjustment experience. Users can complete measurement and adjustment tasks more easily, thereby improving work efficiency and satisfaction.

[0061] 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: 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 tested is R, the distance between the bubble at the top of the sample to be tested and the center of the top plane of the sample to be tested is Y, and the angle between the contact plate 118 and the top plane of the sample to be tested is θ.

[0062] According to an embodiment of the present invention, a guide groove 124 is formed 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 .

[0063] In one embodiment of the present invention, the long hole 112 is not only connected to the slide groove 114, but also has an additional guide groove 124 on the side wall facing the second housing 106. This design is intended to allow the first position measuring member 104 to slide in the guide groove 124, thereby achieving accurate measurement of a specific position inside or outside the housing.

[0064] 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.

[0065] The first position measuring member 104 is designed to be slidably connected in the guide groove 124. This connection method can be direct (for example, through a slide rail, a slider, etc.) or indirect (for example, through a certain connecting member or an intermediate member). In either case, it is ensured that the first position measuring member 104 can slide smoothly and firmly in the guide groove 124.

[0066] 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, it can ensure higher accuracy and stability during the measurement process. This design helps to reduce errors and improve the accuracy of measurement. The design of the guide groove 124 and the first position measuring member 104 makes the measurement process more flexible and efficient. The user can quickly achieve the required measurement by adjusting the position of the first position measuring member 104 in the guide groove 124 without 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.

[0067] According to an embodiment of the present invention, a second opening 126 is opened on the first housing 100 along the height direction of the first housing 100 , and the second position measuring member 110 is inserted into the second opening 126 .

[0068] In one embodiment of the present invention, in order to further enhance the measurement function and flexibility of the device, a second opening 126 is provided along the height direction of the first housing 100. The design of the second opening 126 allows the second position measuring member 110 to be inserted from the outside of the housing into the inside of the housing, thereby achieving accurate measurement of the inside of the housing or structures associated therewith.

[0069] The second opening 126 is an opening located on the side wall or top / bottom of the first housing 100 and extends along the height direction of the housing. The design of the second opening 126 allows the second position measuring member 110 to be easily inserted into the housing from the outside without complicated internal assembly.

[0070] The second position measuring member 110 is designed to be inserted into the second opening 126, and once inserted, it can contact the interior of the housing or a structure associated therewith to achieve accurate measurement. Such contact can be direct (e.g., through the contact between the end of the measuring member and the surface to be measured) or indirect (e.g., through some kind of measuring probe or sensor).

[0071] 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 accurately measure the interior of the shell or the structure associated therewith through the second position measuring member 110, so as to obtain 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 to different measurement needs more flexibly. The user can choose measuring members of different sizes or types as needed to meet specific measurement requirements. Compared with the traditional internal measurement method, 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 in 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.

[0073] 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 device 108 to be inserted from the outside of the shell into the inside of the shell or into a structure associated therewith, thereby achieving accurate measurement of these structures.

[0074] The mounting hole 128 is located on the side wall of the second housing 106, and its position and size are precisely designed to ensure that the second radius measuring piece 108 can be smoothly and firmly inserted therein. This mounting hole 128 not only provides a convenient insertion channel for the measuring piece, but also ensures stability and accuracy during the measurement process.

[0075] The second radius measuring member 108 is designed to be inserted into the mounting hole 128, and once inserted, it can make contact with the interior of the housing or a structure associated therewith to achieve accurate radius measurement. This contact can be direct (e.g., through the end of the measuring member contacting the surface to be measured) or indirect (e.g., through some kind of measuring probe or sensor).

[0076] 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 therewith. This design helps to reduce errors and improve the accuracy of the measurement. 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 to different measurement needs more flexibly. Users can choose measuring pieces of different sizes or types as needed to meet specific measurement requirements. Compared with the traditional internal measurement method, 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 complicated 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.

[0077] 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 in each group of mounting holes 128 . A synchronization rod 130 is connected to one end of the second radius measuring piece 108 facing the inside of the second shell 106 .

[0078] In one embodiment of the present invention, two groups of mounting holes 128 are provided on the side wall of the second housing 106 along its height direction. A second radius measuring member 108 is inserted into each group of mounting holes 128, and a synchronization rod 130 is connected to one end of each of the measuring members facing the inside of the second housing 106. This design is intended to improve the accuracy and efficiency of the measurement, while enhancing the flexibility and practicality of the device.

[0079] Two groups of mounting holes 128 are arranged along the height direction on the side wall of the second housing 106, and each group 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 size information.

[0080] A second radius measuring member 108 is inserted into each group 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 improving the movement stability of the second radius measuring member 108.

[0081] Each second radius measuring member 108 is connected to a synchronization rod 130 at one end facing the inside of the second housing 106. The function of these synchronization rods 130 is to maintain the synchronous movement between the upper and lower second radius measuring members 108 during the measurement process, thereby ensuring the accuracy and consistency of the measurement. Through the connection of the synchronization rods 130, when one of the second radius measuring members 108 moves, the other second radius measuring member 108 will also move accordingly to maintain the relative position relationship between the two.

[0082] By introducing the design of the synchronization rod 130, the present invention can ensure the synchronous movement of the two second radius measuring pieces 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. Since two sets of mounting holes 128 and two second radius measuring pieces 108 are provided, the user can perform simultaneous measurements at different height positions, thereby greatly improving the measurement efficiency. This design enables the user to obtain the required dimensional information more quickly and improves work efficiency. Compared with the traditional single-point measurement method, the present invention realizes 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 in 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.

[0083] According to an embodiment of the present invention, a third radius measuring member 134 is disposed at the center of the first shell 100 . A bracket 132 is connected to the first shell 100 . The third radius measuring member 134 can be movably inserted into the bracket 132 .

[0084] In one embodiment of the present invention, a bracket 132 for mounting a third radius measuring member 134 is designed at the center of the first housing 100. The bracket 132 not only allows the third radius measuring member 134 to perform accurate radius measurement at the center of the first housing 100, but also enables the measuring member to be flexibly moved and adjusted in position.

[0085] The center position of the first shell 100 is designed to accommodate and install a bracket 132, and the bracket 132 is used to install and support a third radius measuring piece 134. The third radius measuring piece 134 is specially designed to accurately measure the radius of the bubble at the center position of the top of the sample to be measured, and its size and shape match the center position of the first shell 100.

[0086] In order to enhance the flexibility and practicality of the third radius measuring member 134, a bracket 132 is further connected to the first housing 100. The bracket 132 is designed to stably support the third radius measuring member 134 and allow the third radius measuring member 134 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 meet different measurement requirements.

[0087] 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 perform translational motion on the bracket 132, but also perform rotation or tilting and other actions. This mobility enables the third radius measuring member 134 to be more flexible to adapt to different measurement scenarios and objects. In actual detection, the radius of the bubble at the center of the top plane of the sample to be tested can be measured by direct reading.

[0088] By setting the third radius measuring piece 134 at the center of the first shell 100 and connecting 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 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 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.
