[0031] like Figures 1 to 5 As shown, according to an embodiment of the present utility model, a detection device for testing the mechanical properties of flexible parts is proposed, including a frame portion 10 and a connecting member 20, the frame portion 10 includes a plurality of mounting rods 11 that can be assembled and connected, the connecting member 20 is arranged on the mounting rod 11 and can slide relative to the mounting rod 11, and the connecting member 20 is used to connect the flexible parts.

[0032] According to the fixture 100 of the utility model, it is used for the mechanical property test of the flexible part. The frame part 10 is constructed by selecting the installation rods 11 of the appropriate number and length according to the size and shape of the flexible part. The flexible part is connected to the frame through the slidable connecting member 20. The connecting member 20 can slide along the installation rod 11 to adapt to different test configurations and mechanical loading requirements. The specific method of testing the flexible part is to apply a predetermined force to the connecting member 20 through an external force (such as a push-pull force), and the connecting member 20 drives the flexible part to undergo a specific deformation. Then, the corresponding deformation data of the flexible part can be measured by using relevant measuring tools (such as a strain gauge or a force sensor, etc.). The fixture 100 of the utility model is low in cost and can be quickly adjusted and reconfigured at different test stages, thereby improving the test efficiency and reducing the time required for setting and adjustment. At the same time, it also increases the versatility of the fixture 100, so that it can be more widely used in a variety of mechanical property test scenarios of flexible parts.

[0033] It is understandable that a slide groove is provided on the mounting rod 11, and the connecting member 20 is slidably arranged in the slide groove. By providing a slide groove on the mounting rod 11 and allowing the connecting member 20 to be positioned in the slide groove in a slidable manner, the fixture 100 provides a high degree of adaptability to the flexible member, so that the fixture 100 can adapt to flexible members of different sizes and shapes, and provide support for diverse test requirements. At the same time, the adjustment process of the fixture 100 is simplified, so that the operator can quickly and easily adjust the position of the connecting member 20 according to the test requirements. The easy-to-operate feature reduces the test preparation time and improves the overall test efficiency.

[0034] Specifically, the mounting rod 11 is a rectangular parallelepiped structure, and multiple sides of the mounting rod 11 are provided with slide grooves. By providing slide grooves on multiple sides of the mounting rod 11, the fixture 100 can not only adjust the position of the connector 20 in one direction, but also can adjust it in multiple directions. This design greatly enhances the adaptability of the fixture 100, making it suitable for more complex mechanical property tests of flexible parts, including test scenarios that require multi-directional loading or deformation. At the same time, by making full use of each side of the mounting rod 11, the space utilization rate of the fixture 100 is improved, so that each mounting rod 11 can become part of multiple test configurations. This efficiency improvement is particularly important for occasions where laboratory space is limited or multiple tests need to be performed simultaneously.

[0035] Specifically, the connector 20 is provided with a slider 23, which is received in the slide groove. The slider 23 can ensure that the connector 20 slides forward and backward in the slide groove, and prevents the connector 20 from being separated from the slide groove. More specifically, a screw rod can be passed through the slider 23, and the slider 23 can be fixed by rotating the screw rod so that the screw rod abuts against the inner wall of the slide groove. Once the screw rod is tightened, the pressure between the slider 23 and the inner wall of the slide groove increases, ensuring that the position of the connector 20 remains unchanged during the application of external force or the deformation test, thereby ensuring the stability and reliability of the test.

[0036] It is understandable that the fixture 100 further includes a fastener 30, and two adjacent mounting rods 11 are connected by the fastener 30. Specifically, the fastener 30 is an L-shaped angle steel, and bolt holes 31 are provided on both sides of the L-shaped steel. The positions of the bolt holes 31 are arranged corresponding to the positions of the chute. One end of the bolt passes through the bolt hole 31 and abuts against the inner wall of the chute, and the other end of the bolt is used for convenient rotation. An elastic washer is also provided at one end of the bolt abutting against the inner wall of the chute to prevent the bolt from damaging the inner wall of the chute. By providing the fastener 30, the connection stability between adjacent mounting rods 11 can be effectively increased. At the same time, the design of the fastener 30 simplifies the assembly and disassembly process between the mounting rods 11, making the construction and reconfiguration of the fixture 100 faster and more convenient. This design is particularly useful for laboratory environments that require frequent changes in test configurations or conduct a variety of different tests.

[0037] In some embodiments, the fixing device 100 further includes a limiting rod, and a limiting hole 111 and a slot 112 are provided on the mounting rod 11. The limiting rod can pass through the limiting hole 111 and the slot 112 and abut against the connecting member 20. The limiting hole 111 and the slot 112 penetrate the mounting rod 11. When the limiting rod is inserted into the limiting hole 111 and the slot 112, the interior of the slot is completely penetrated by the limiting rod. When the connecting member 20 moves to a specific position, the limiting rod is inserted into the limiting hole 111 and the slot 112 corresponding to the position of the connecting member 20. The limiting rod can abut against the connecting member 20 to prevent the connecting member 20 from rebounding. By using the limiting rod and the preset limiting hole 111 and the slot 112, the precise position control of the connecting member 20 or the slider 23 can be achieved. This control mechanism ensures that the fixing and loading points of the flexible member can be kept at the predetermined positions during the mechanical property test, thereby improving the accuracy and repeatability of the test results.

[0038] In some embodiments, the fixture 100 further includes casters, which are disposed at the bottom of the frame portion 10. In addition, the casters are equipped with a locking mechanism, which allows the casters to be locked when necessary to prevent the movement of the fixture 100, thereby ensuring the stability of the device when conducting mechanical property tests. In addition, the caster design supports 360-degree rotation, making the movement and positioning of the fixture 100 more flexible and convenient. The casters disposed at the bottom of the frame portion 10, coupled with their locking and rotation functions, make it not only easy to move the fixture 100 to the desired position, but also convenient for the operator to move it to other locations or store it when the test is completed or storage is required, thereby improving the overall ease of use.

[0039] In some embodiments, the mounting rod 11 is an aluminum profile mounting rod 11. The aluminum profile mounting rod 11 not only provides the required structural strength and stability, but also makes the entire fixture 100 easy to move due to the lightweight characteristics of the aluminum profile. In addition, the modular design and easy processing characteristics of the aluminum profile allow for quick assembly and disassembly, making it easy to adjust the size and shape of the frame according to different test requirements. At the same time, the mounting rod 11 constructed of aluminum profiles ensures that the fixture 100 can maintain good structural stability and durability even when a large force is applied or a long test is performed, thereby improving the reliability of the test.

[0040] In some embodiments, the connector 20 includes a hook or ring 21. The hook or ring 21 can quickly connect and release the flexible member, and the position of the hook or ring 21 can be adjusted to accommodate flexible members of different sizes and shapes. The hook or ring 21 is firmly connected to the slider 23 via a boss structure 22. The design of the hook or ring 21 makes the connection and release process of the flexible member quick and easy, greatly reducing the test preparation time and improving the test efficiency. This quick connection and release mechanism is particularly important for laboratories that conduct a large number of sample tests or need to frequently change test samples. The simple operation mechanism of the hook or ring 21 not only reduces the difficulty of operation, but also reduces the manufacturing and maintenance costs of the fixture 100 due to its simple design.

[0041] In some embodiments, the frame portion 10 is a cubic structure. The frame portion 10 is designed with a cubic structure so that the entire fixture 100 has a uniform distribution of mechanical properties in the spatial layout. The cubic structure not only enhances the overall stability of the frame, but also allows the flexible parts to be tested from multiple directions, including but not limited to mechanical property tests such as tension, compression and bending. In addition, the cubic structure design takes into account the need for easy assembly and disassembly, and realizes rapid configuration changes and adaptive adjustments through modular components.

[0042] In another specific embodiment, a fixture 100 for testing the mechanical properties of a flexible part is provided, which is intended to improve test efficiency, reduce setup time, and adapt to the testing requirements of various flexible parts. The fixture 100 is particularly suitable for testing various mechanical properties such as tension, compression, and bending, and can be quickly adjusted and reconfigured to meet the requirements of different test stages.

[0043] Specifically, the fixture 100 is composed of a cubic frame portion 10, which is modularly constructed of multiple aluminum profile mounting rods 11, so that the entire device is not only stable but also easy to move and reconfigure. A slide groove is designed on the mounting rod 11, and the matching connector 20 includes an adjustable hook or ring 21, which can slide along the slide groove to meet the testing requirements of flexible parts of different shapes and sizes. The slider 23 on the connector 20 is fixed by a screw to ensure stability during the test. The device further includes an L-shaped angle steel fastener 30, which improves the connection stability between adjacent mounting rods 11, and the use of an elastic gasket prevents damage to the inner wall of the slide groove. The design of the limit rod and the limit hole 111 slide groove; 112 allows precise control of the position of the connector 20 and improves the test accuracy. The casters equipped at the bottom contain a locking mechanism and support 360-degree rotation, which increases the mobility and stability of the device. By applying external force to the connector 20, the device can accurately measure the mechanical properties of the flexible member under specific deformation. It is suitable for various test scenarios such as stretching, compression, and bending, effectively reducing the test preparation time and improving the test efficiency and versatility.

[0044] The test method is to apply a predetermined force to the connector 20 through an external force (such as a push-pull force), and the connector 20 drives the flexible member to undergo a specific deformation. Use relevant measuring tools (such as a strain gauge or a force sensor) to record the response of the flexible member to measure the deformation data of the flexible member. The fixture 100 reduces the test preparation time and improves the overall test efficiency through a simplified adjustment process, high adaptability and fast operation of the connector 20.

[0045] The above is only a preferred specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
