Description

Technical Field

[0001] This utility model relates to the field of materials testing technology, and in particular to a new material tensile property testing device. Background Technology

[0002] Tensile property testing of new materials is a test method that determines material properties by applying axial tensile load. It is a fundamental project in materials mechanical property testing, helping to evaluate the material's performance during elastic deformation, plastic deformation, and fracture processes, providing important information for engineering design, material selection, quality control, and product safety. During the test, the material undergoes elastic deformation, plastic deformation, and finally fracture. The entire process is visually reflected in the tensile curve, which reflects the material's performance characteristics. In existing technologies, when testing new materials, the material is typically clamped on both sides and pulled to both sides (mainly applying tensile stress in a single direction) to test its tensile properties. However, in practical applications, some materials (e.g., packaging bags, airbags, films, and other flexible membrane materials) need to be stretched simultaneously in multiple directions. For the testing of these materials, burst testing can be used to simulate this. Existing testing devices typically can only perform a single standard tensile test or only a burst test, and cannot simultaneously perform both testing functions on the same device. This necessitates the use of different testing equipment when multi-faceted performance evaluations of materials are required, increasing testing costs and operational complexity, and potentially failing to provide a comprehensive understanding of the material's performance under various stress states. Therefore, existing technologies urgently need improvement to address these issues. Utility Model Content

[0004] This utility model discloses a new material tensile property testing device, including a box and a connecting plate. The box has an opening that is adapted to the connecting plate. The connecting plate can be inserted into the box through the opening. A placement groove is provided on one side of the connecting plate, and a placement ring is installed in the placement groove for placing the material on one side of the placement ring. A support plate assembly is installed in the inner cavity of the box for supporting the connecting plate inserted into the inner cavity of the box. A horizontal moving device is provided on one side of the inner wall of the box. A pressing component is installed on the drive end of the horizontal moving device to press the material placed on one side of the placement ring. An air pumping component is provided on one side of the box. The air pumping component is connected to the pressing component to cause the material pressed by the pressing component to deform. The placement ring includes a second semicircular ring and a first semicircular ring fixedly connected to the inner cavity of the placement groove.

[0005] Furthermore, the support plate assembly includes several connecting rods disposed on the inner wall of the box cavity and a support plate disposed on one side of the connecting rods for supporting the connecting plate.

[0006] Furthermore, the pressing assembly includes a pressure plate disposed at the drive end of the horizontal moving device and a pressure ring disposed on one side of the pressure plate, the pressure ring being adapted to the placement ring.

[0007] More specifically, the lifting drive device includes a groove on one side of the connecting plate, sliding grooves on both sides of the inner cavity of the groove, a slider slidably disposed in the corresponding sliding groove, and a threaded rod rotatably disposed in one of the sliding grooves. The threaded rod movably passes through the corresponding slider and is threadedly connected to the slider. A rotary motor is provided on the top of the connecting plate. The drive end of the rotary motor movably passes through the connecting plate and is connected to the threaded rod. An mounting block is fixedly installed between the two sliders.

[0008] Preferably, the groove is connected to the placement slot, and the mounting block is semi-circular.

[0009] Furthermore, the clamping assembly includes a mounting groove formed on one side of the mounting block, a guide block slidably disposed in the mounting groove, and a clamping block fixedly mounted on one side of the guide block. A bolt is rotatably connected to the mounting block, and the bolt moves through the guide block and is threadedly connected to the guide block. The bolt is used to rotate the guide block to move within the mounting groove, so that the clamping block clamps the material on the second semi-circular ring.

[0010] Furthermore, a clamping groove is provided on one side of the pressure ring, and the clamping groove is adapted to the clamping block.

[0011] Furthermore, the air pump assembly includes an air pump located on one side of the housing and an air inlet pipe located at the output end of the air pump. An air inlet and an air outlet are provided on one side of the pressure plate, extending to the inner circumference of the pressure ring. One end of the air inlet pipe movably passes through the housing and is connected to the air inlet, used to pump air into the inner cavity of the pressure ring through the air inlet pipe to push the material to deform. An exhaust pipe is connected to the air outlet for exhausting air. Solenoid valves are installed on both the air inlet pipe and the exhaust pipe.

[0012] Furthermore, an opening is provided on one side of the front of the box, and a transparent window is rotatably installed inside the opening for opening the transparent window to retrieve the torn material.

[0013] Furthermore, a transparent observation window is installed on one side of the enclosure, and a detection module is set on the other side of the enclosure for detecting the deformation of the material through the transparent observation window.

This technical solution solves the technical problem that existing testing devices cannot simultaneously perform standard tensile tests and burst tests. It enables the testing of new materials, especially flexible film materials, in both standard tensile and burst modes on a single device, improving the comprehensiveness and efficiency of testing, reducing testing costs and operational complexity, and providing more comprehensive data support for material performance evaluation.

[0025] Tensile property testing of new materials is a fundamental project in materials mechanical property testing, and it is crucial for evaluating the performance of materials under different stress states. In existing technologies, tensile property testing of materials typically employs a standard tensile test, which involves clamping the material at both ends and applying a unidirectional tensile load. However, for some flexible membrane materials that need to withstand multi-directional tension in practical applications, such as packaging bags, airbags, and films, a unidirectional tensile test cannot comprehensively reflect their performance. Although burst testing can be used to simulate multi-directional forces, existing testing devices often only perform one of the standard tensile test or burst test, failing to achieve both testing functions on a single device, which increases testing costs and complexity. This invention provides a new material tensile property testing device, aiming to solve the problem of single-function testing devices in existing technologies. Through ingenious structural design, the device can simultaneously perform standard tensile tests and burst tests, thereby providing a more comprehensive evaluation of the tensile properties of new materials. The device achieves two different testing modes by incorporating a detachable placement ring, a horizontally movable holding component, an inflation component for inflation, and a lifting drive device for moving a portion of the placement ring.

[0026] This utility model provides a novel material tensile property testing device, mainly comprising a housing 1, a connecting plate 2, a support plate 6, a horizontal moving device 7, a pressure plate 8, a pressure ring 9, an air pump 10, and a testing module 12. The housing 1 serves as the main frame of the device, housing the other components. The connecting plate 2 holds the material to be tested and connects to the housing 1 via a connector 5. The support plate 6 is located within the housing 1, supporting the inserted connecting plate 2. The horizontal moving device 7 is located on one side of the inner wall of the housing 1, driving the pressure plate 8 to move horizontally. The pressure ring 9 is located on one side of the pressure plate 8, cooperating with the placement ring 4 on the connecting plate 2. The air pump 10 is located on one side of the housing 1, inflating the inner cavity of the pressure ring 9. The testing module 12 is located on one side of the housing 1, detecting the deformation of the material.

[0027] Specifically, see Figure 1 , Figure 2 and Figure 7 The housing 1 has a socket 5, which is adapted to the connecting plate 2, allowing the connecting plate 2 to be easily inserted into or removed from the housing 1. See also Figure 1 and Figure 2 The inner cavity of housing 1 is equipped with a support plate assembly to support the connecting plate 2 inserted into the inner cavity of housing 1. (See also...) Figure 1 and Figure 3 A placement groove 3 is provided on one side of the connecting plate 2, and a placement ring 4 is installed in the placement groove 3 for placing materials on one side of the placement ring 4. See also Figure 3 and Figure 5The placement ring 4 includes a second semicircular ring 14 and a first semicircular ring 13 fixedly connected to the inner cavity of the placement groove 3. See also Figure 1 , Figure 2 and Figure 3 A lifting drive device is provided on one side of the connecting plate 2. The drive end of this lifting drive device is connected to the second semi-circular ring 14 and is used to drive the second semi-circular ring 14 to move vertically. The lifting drive device is also equipped with a clamping assembly for clamping one end of the material. See also Figure 1 , Figure 2 and Figure 6 A horizontal moving device 7 is provided on one side of the inner wall of the housing 1. A pressing assembly is mounted on the drive end of the horizontal moving device 7 for pressing material placed on one side of the placement ring 4. The pressing assembly includes a pressure plate 8 and a pressing ring 9 disposed on one side of the pressure plate 8, which is adapted to the placement ring 4. See also... Figure 1 and Figure 6 An air-inflating assembly is provided on one side of the housing 1. This assembly includes an air pump 10, which is connected to the pressure-holding assembly and is used to inflate the inner cavity of the pressure ring 9, thereby causing deformation of the material held by the pressure-holding assembly. See [link to other documentation] Figure 1 and Figure 7 A detection module 12 is provided on one side of the housing 1 to detect the deformation of the material.

[0028] Compared with existing technologies, the novel material tensile property testing device provided by this invention has significant advantages. Existing devices typically only perform a single standard tensile test or burst test, while this invention, by designing the placement ring as both a fixed and movable part, and incorporating a horizontally moving holding component, a lifting drive device, and an air-inflating component, allows for flexible switching of testing modes on a single device. During the burst test, the holding component presses against the material edge, and the air-inflating component inflates the material, causing it to expand and deform. During the standard tensile test, the lifting drive device moves the movable part of the placement ring, stretching the material. This integrated design avoids the inconvenience and cost of using multiple devices, improves testing efficiency and convenience, and is particularly suitable for new materials requiring multi-faceted performance evaluation, such as flexible film materials.

[0029] This novel material tensile property testing device can achieve two different testing modes. During the burst test, the material to be tested is placed on the placement ring 4 within the placement groove 3 of the connecting plate 2. The connecting plate 2 is inserted into the housing 1 through the insertion port 5, with one side of it fitting against the support plate 6. The horizontal moving device 7 drives the pressure plate 8 to move, and the pressure ring 9 on one side of the pressure plate 8 fits against the placement ring 4, pressing the edge of the material between the placement ring 4 and the pressure ring 9, thus forming a cavity between the material and the pressure ring 9. The air pump 10 injects gas into this cavity through the air pumping assembly. As the air pressure inside the cavity continuously increases, it pushes the material to undergo elastic deformation and move through the placement groove 3 towards the receiving groove 11 on the side of the support plate 6. During the elastic deformation process, the detection module 12 detects the deformation parameters such as strain, stress, and radius of the material after deformation. During the standard tensile test, one end of the material is clamped on the second semi-circular ring 14 by the clamping assembly on the lifting drive device, and the other end is placed on the first semi-circular ring 13. The connecting plate 2 is inserted into the housing 1 through the insertion port 5. The horizontal moving device 7 drives the pressure plate 8 and the pressure ring 9 to move, causing the pressure ring 9 to press against the material on the first semi-circular ring 13. At this time, since the first semi-circular ring 13 and the second semi-circular ring 14 are relatively separated, the pressure ring 9 will not press against the material on the second semi-circular ring 14 when pressing against the material on the first semi-circular ring 13. Subsequently, the lifting drive device drives the mounting block 16 connected to the second semi-circular ring 14 to move upward, thereby stretching the material located at both ends on the first semi-circular ring 13 and the second semi-circular ring 14 respectively, to test the tensile properties of the material. Through the above two working modes, the device can not only measure the standard tensile properties of the material, but also more realistically simulate the stress state of flexible materials in actual use through inflation testing, thereby gaining a comprehensive understanding of the material's performance. The placement ring 4 is used to position and support the material; the horizontal moving device 7, the pressure plate 8, and the pressure ring 9 are used to press the material edges together to form a sealed cavity during the burst test; the air pump 10 is used to provide inflation pressure; the lifting drive device and the second semicircular ring 14 are used to apply tensile load to the material during the standard tensile test; the clamping assembly is used to fix one end of the material; and the detection module 12 is used to measure the deformation data of the material.

[0030] Furthermore, this application also proposes that the horizontal moving device be a cylinder.

[0031] See Figure 2 The horizontal moving device 7 is located on one side of the inner wall of the housing 1 and is used to drive the pressure plate 8 to move horizontally. As a specific implementation, the horizontal moving device 7 can be implemented using a cylinder.

[0032] The horizontal moving device 7 employs a cylinder, which is an actuator capable of converting gas pressure energy into mechanical energy to perform linear reciprocating motion. By controlling the gas pressure and flow rate entering the cylinder, the extension and retraction of the piston rod can be precisely controlled, thereby driving the pressure plate 8 connected to the piston rod to move horizontally. A standard cylinder can be selected, and its structure and working principle are well known to those skilled in the art.

[0033] By employing a cylinder as the horizontal movement device 7, a stable and reliable linear driving force can be provided, enabling precise control of the pressure plate 8. This is crucial for accurately pressing the pressure ring 9 onto the placement ring 4 to form a sealed cavity during burst testing. The cylinder has advantages such as simple structure, fast response speed, and ease of control, ensuring that the pressing assembly completes the pressing action smoothly and accurately, thus improving the stability and efficiency of the device during burst testing.

[0034] Furthermore, this application also proposes that the lifting drive device includes a groove formed on one side of the connecting plate, sliding grooves formed on both sides of the inner cavity of the groove, a slider slidably disposed in the corresponding sliding groove, and a threaded rod rotatably disposed in one of the sliding grooves. The threaded rod movably passes through the corresponding slider and is threadedly connected to the slider. A rotary motor is provided on the top of the connecting plate. The drive end of the rotary motor movably passes through the connecting plate and is connected to the threaded rod. An mounting block is fixedly installed between the two sliders. The second semicircular ring is fixedly installed on one side of the mounting block.

[0035] See Figure 3 and Figure 4 The lifting drive device is specifically installed within a groove 15 on one side of the connecting plate 2. The lifting drive device includes two sliding grooves 17 located on both sides of the inner cavity of the groove 15, and sliders 18 slidably disposed within the corresponding sliding grooves 17. A threaded rod 19 is rotatably disposed within one of the sliding grooves 17, the threaded rod 19 passing through the corresponding slider 18 and threadedly connected to it. A rotary motor 20 is located at the top of the connecting plate 2, the drive end of which passes through the connecting plate 2 and is connected to the threaded rod 19 to drive the threaded rod 19 to rotate. A mounting block 16 is fixedly installed between the two sliders 18, and the second semi-circular ring 14 is fixedly installed on one side of the mounting block 16.

[0036] The lifting drive device uses a screw and nut transmission mechanism to achieve the lifting and lowering movement of the second semi-circular ring 14. A rotary motor 20 provides rotational power, driving the threaded rod 19 to rotate via its drive end. Since the slider 18 is threadedly connected to the threaded rod 19, the rotation of the threaded rod 19 drives the slider 18 to move axially along the threaded rod 19. Simultaneously, the slider 18 is slidably positioned within a groove 17, which guides the movement of the slider 18, ensuring it moves in a straight line. Because the mounting block 16 is fixedly installed between the two sliders 18, the movement of the slider 18 drives the mounting block 16 to move along the direction of the groove 17. The second semi-circular ring 14, fixedly connected to the mounting block 16, also moves accordingly, thereby achieving the lifting and stretching of the material clamped on the second semi-circular ring 14. This lifting drive device has a compact structure, smooth transmission, and can achieve precise position control of the second semi-circular ring 14.

[0037] By employing a lifting drive device consisting of a rotary motor 20, a threaded rod 19, a slider 18, and a groove 17, this invention can precisely control the moving distance and speed of the second semi-circular ring 14. This is crucial for applying precise tensile strain to the material during standard tensile testing. The screw drive mechanism possesses high transmission accuracy and self-locking properties, ensuring the stability and repeatability of the tensile process, thereby obtaining accurate and reliable tensile performance data. Compared to solutions relying solely on the overall structure, this additional technical feature provides a precise and reliable driving and control method for standard tensile testing, significantly improving the device's testing performance.

[0038] Furthermore, this application also proposes that a clamping component be provided on one side of the mounting block for clamping one end of the material.

[0039] See Figure 3 , Figure 4 and Figure 5 The mounting block 16 is fixedly installed between the sliders 18 of the lifting drive device and is fixedly connected to the second semi-circular ring 14. A clamping assembly is provided on one side of the mounting block 16. The clamping assembly is used to reliably fix one end of the material to be tested on the mounting block 16 during a standard tensile test, so that the material can move together with the mounting block 16 and the second semi-circular ring 14.

[0040] This clamping assembly is a device for fixing materials. Its specific structure can be implemented in various ways, such as mechanical clamps, pneumatic clamps, hydraulic clamps, etc., as long as it can firmly clamp one end of the material. This clamping assembly is mounted on the mounting block 16, allowing one end of the material to move synchronously with the second semi-circular ring 14 that moves with the lifting drive device.

[0041] By providing a clamping assembly on the mounting block 16, this invention provides the necessary means of material fixation for standard tensile testing. In the standard tensile test mode, one end of the material is clamped and fixed to the second semi-circular ring 14 by the clamping assembly, while the other end rests on the stationary first semi-circular ring 13. When the lifting drive device moves the mounting block 16 and the second semi-circular ring 14 upwards, the clamped end of the material also moves upwards, thereby applying a tensile load to the material. This additional technical feature ensures that the material can be stably fixed and stretched during the tensile process, and is an important component in realizing the function of the standard tensile test, improving the reliability and accuracy of the tensile test.

[0042] Furthermore, this application also proposes that the clamping assembly includes a mounting groove formed on one side of the mounting block, a guide block slidably disposed in the mounting groove, and a clamping block fixedly mounted on one side of the guide block. A bolt is rotatably connected to the mounting block, and the bolt moves through the guide block and is threadedly connected to the guide block, so as to rotate the bolt to drive the guide block to move in the mounting groove, so that the clamping block clamps the material on the second semi-circular ring.

[0043] See Figure 5 The clamping assembly specifically includes a mounting groove 24 formed on one side of the mounting block 16. A guide block 26 is slidably disposed within the mounting groove 24. A clamping block 25 is fixedly mounted on one side of the guide block 26. A bolt 27 is rotatably connected to the mounting block 16, the bolt 27 passing through the guide block 26 and threadedly connected to the guide block 26.

[0044] The clamping assembly clamps the material through the cooperation of bolt 27, guide block 26, and clamping block 25. When bolt 27 is rotated, due to the threaded connection between bolt 27 and guide block 26, the rotation of bolt 27 causes guide block 26 to move linearly within mounting groove 24. Clamping block 25, fixedly connected to guide block 26, also moves accordingly. By controlling the rotation direction of bolt 27, clamping block 25 can be moved closer to or away from the second semi-circular ring 14. When clamping block 25 moves closer to the second semi-circular ring 14, the material placed on the second semi-circular ring 14 can be clamped between clamping block 25 and the second semi-circular ring 14, thereby fixing the material. The cooperation between mounting groove 24 and guide block 26 ensures accurate and stable movement of clamping block 25.

[0045] By employing this structure where the guide block 26 and clamping block 25 are moved by the bolt 27, this invention provides a clamping assembly that is easy to operate and has adjustable clamping force. This structure is simple and reliable, effectively fixing one end of the material to the second semi-circular ring 14, which moves with the lifting drive device, providing a stable clamping foundation for standard tensile testing. Compared to merely mentioning the clamping assembly in general terms, this additional technical feature provides a specific implementation method, improving the adaptability of the device to materials of different thicknesses and the reliability of clamping when performing standard tensile tests.

[0046] Furthermore, this application also proposes that a clamping groove is provided on one side of the pressure ring, and the clamping groove is adapted to the clamping block.

[0047] See Figure 2 and Figure 6 A pressure ring 9 is provided on one side of the pressure plate 8. The pressure ring 9 is used to cooperate with the placement ring 4 to press the edge of the material during the burst test. On one side of the pressure plate 8, specifically near the pressure ring 9, a clamping groove 28 is provided. The shape and size of the clamping groove 28 are adapted to the clamping block 25 in the clamping assembly.

[0048] The clamping groove 28 is a recess located on one side of the pressure plate 8. Its function is to allow the clamping block 25 on the clamping assembly to insert into the clamping groove 28 when the horizontal moving device 7 moves the pressure plate 8 and pressure ring 9 forward to press the material edge during a burst test, provided that the clamping block 25 is located on the moving path of the pressure plate 8. This adaptive design ensures that the pressure plate 8 and pressure ring 9 can move smoothly into position and tightly press the material edge without interfering with the clamping block 25.

[0049] By creating a clamping groove 28 on one side of the pressure plate 8 that matches the clamping block 25, this invention solves the problem of potential interference between the clamping assembly and the pressure plate and pressure ring during burst testing. This structural design eliminates the need to disassemble or adjust the position of the clamping assembly when switching between two test modes, improving the ease of operation of the device. Especially when the pressure ring 9 presses down on the material on the first semi-circular ring 13 and the second semi-circular ring 14 (in burst testing mode, the material edge is pressed between the entire placement ring and the pressure ring), the clamping block 25 can smoothly enter the clamping groove 28, ensuring tight compression and cavity sealing, providing structural protection for the successful conduct of the burst test. This additional technical feature, through ingenious structural cooperation, improves the compatibility and reliability of the device under different test modes.

[0050] Furthermore, this application also proposes that the air pump assembly includes an air pump disposed on one side of the housing and an air inlet pipe disposed at the output end of the air pump. An air inlet and an air outlet are provided on one side of the pressure plate, and the air inlet and air outlet extend to the inner circumference of the pressure ring. One end of the air inlet pipe movably passes through the housing and is connected to the air inlet, for pumping air into the inner cavity of the pressure ring through the air inlet pipe to push the material to deform. An exhaust pipe is connected to the air outlet for exhausting air. Solenoid valves are installed on both the air inlet pipe and the exhaust pipe.

[0051] See Figure 1 and Figure 6 The air pump assembly includes an air pump 10 located on one side of the housing 1. The output end of the air pump 10 is connected to an air inlet pipe 21. An air inlet 29 and an air outlet 30 are provided on one side of the pressure plate 8, extending to the inner circumference of the pressure ring 9. One end of the air inlet pipe 21 movably passes through the housing 1 and communicates with the air inlet 29, for delivering the gas generated by the air pump 10 to the inner cavity of the pressure ring 9. An exhaust pipe 22 is connected to the air outlet 30 for discharging the gas from the inner cavity of the pressure ring 9. Solenoid valves 23 are installed on both the air inlet pipe 21 and the exhaust pipe 22.

[0052] The air pump assembly provides air through the air pump 10 and delivers the gas to the inner cavity of the pressure ring 9 via the air inlet pipe 21. The air inlet 29 and air outlet 30 are located on one side of the pressure plate 8 and extend to the inner circumference of the pressure ring 9, ensuring that gas can effectively enter and exit the cavity formed between the pressure ring 9 and the material. Solenoid valves 23 on the air inlet pipe 21 and the exhaust pipe 22 control the flow direction and on / off of the gas. During a burst test, by opening the solenoid valve 23 on the air inlet pipe 21 and closing the solenoid valve 23 on the exhaust pipe 22, the air pump 10 can inject gas into the cavity, increasing the air pressure inside the cavity and causing the material to deform. After the test, by closing the solenoid valve 23 on the air inlet pipe 21 and opening the solenoid valve 23 on the exhaust pipe 22, the gas in the cavity can be discharged, allowing the material to return to its original shape or be easily removed.

[0053] By incorporating an air pump 10, an air inlet pipe 21, an air outlet pipe 22, and corresponding solenoid valves 23, this invention achieves precise control over the gas pressure and flow within the pressure ring 9. This is crucial for conducting burst tests, allowing for adjustment of the inflation speed and pressure as needed to simulate different burst conditions. The solenoid valves 23 further automate and refine gas control, enhancing the controllability and safety of burst tests. Compared to simply mentioning the air pump assembly, this additional technical feature provides a concrete implementation structure and control method, significantly improving the performance and reliability of the device in burst tests.

[0054] Furthermore, this application also proposes that a transparent observation window be installed on one side of the enclosure, and a detection module be provided on one side of the enclosure for detecting the deformation of the material through the transparent observation window.

[0055] See Figure 1 and Figure 7 A transparent observation window 32 is installed on one side of the enclosure 1. On the same side of the enclosure 1, a detection module 12 is provided. The detection module 12 observes and detects the material inside the enclosure 1 through the transparent observation window 32 to obtain the deformation of the material.

[0056] The transparent observation window 32 is made of a transparent material, such as glass or transparent plastic, allowing the external detection module 12 to observe the material inside the housing 1. The detection module 12 is a device for measuring material deformation. In a preferred embodiment, the detection module 12 may include a laser extensometer disposed on one side of the housing 1. Two symmetrical reflective strips are arranged in the central region of the material; these reflective strips deform synchronously with the material, and the laser extensometer is used to obtain the displacement changes of these reflective strips. By measuring the change in distance between the reflective strips, the strain of the material can be calculated. The detection module 12 performs non-contact measurements through the transparent observation window 32, avoiding interference with the material itself.

[0057] By incorporating a transparent observation window 32 on the housing 1 and a detection module 12 located on one side of the housing 1, this invention achieves real-time, non-contact detection of material deformation. The detection module 12, for example using a laser extensometer with reflective strips, can accurately measure the deformation data of the material during burst tests or standard tensile tests. The transparent observation window 32 allows the detection module 12 to conveniently observe and measure the material inside the housing while maintaining the housing's airtightness (during burst tests). This additional technical feature provides a reliable means of obtaining accurate material deformation data, a key step in evaluating the tensile properties of materials, and significantly improves the detection accuracy and functionality of the device.

[0058] Furthermore, this application also proposes that an opening is provided on one side of the front of the box, and a transparent window is rotatably installed in the opening for opening the transparent window to retrieve the torn material.

[0059] See Figure 7 An opening 33 is provided on one side of the front of the housing 1. A transparent window 34 is rotatably installed inside the opening 33. The transparent window 34 can be opened by rotation to allow the operator to remove material fragments that may be torn during the test.

[0060] The opening 33 is a through hole located at the front of the chamber 1, providing access to the interior of the chamber 1. The transparent window 34 is made of a transparent material, such as glass or transparent plastic, and is rotatably installed within the opening 33 via a structure such as a pivot. During normal testing, the transparent window 34 is closed to maintain the airtightness of the chamber 1. When the test is completed, especially after material breakage, the transparent window 34 can be opened by rotating it to easily remove material fragments or perform cleaning from inside the chamber 1.

[0061] By providing an opening 33 with a rotatable transparent window 34 at the front of the housing 1, this invention provides a convenient and quick way to remove materials after testing. Especially in the event of material breakage, the design of this opening and transparent window allows operators to easily remove material fragments without disassembling other parts, improving the ease of operation and maintenance efficiency of the device. Although this additional technical feature does not directly participate in the tensile or bursting process, it facilitates post-test operations and is an important detail that enhances the overall usability of the device.

[0062] Furthermore, this application also proposes that a transparent observation window be installed on one side of the enclosure, and a detection module be provided on one side of the enclosure for detecting the deformation of the material through the transparent observation window.

[0063] See Figure 1 and Figure 7 A transparent observation window 32 is installed on one side of the enclosure 1. On the same side of the enclosure 1, a detection module 12 is provided. The detection module 12 observes and detects the material inside the enclosure 1 through the transparent observation window 32 to obtain the deformation of the material.
