For this purpose, a tensile test device is often used for tensile testing. The tensile test device is a device used to measure the tensile properties of materials, and is usually used to evaluate the strength, ductility and deformation behavior of materials.

[0003] For example, the patent with publication number CN210571720U specifically discloses a shear tensile testing device for thermal insulation materials, which ensures that the thermal insulation materials will not loosen from the clamp when the thermal insulation materials are stretched, effectively ensuring the efficiency of the test, and has a simple structure, easy operation and good practicality.

[0004] In the above patent, the tensile testing device prevents the material from detaching from the clamp when the device performs a tensile test on the material by providing a clamping assembly. However, the testing device is only provided with a single set of testing assemblies, which enables the device to only perform a tensile test on a single set of materials at the same time, and is not convenient for simultaneously testing multiple sets of materials and intuitively comparing the test results, thereby limiting the device's ability to simultaneously test and compare and analyze multiple sets of materials, which may limit the test efficiency and the convenience of data analysis. Therefore, it is necessary to provide a tensile testing device that can simultaneously test multiple sets of materials to solve the above problems.

[0005] It should be noted that the above information disclosed in this background technology section is only for understanding the background technology of the present application concept, and therefore, it may contain information that does not constitute the prior art. Summary of the invention

[0008] Furthermore, a rotation axis is provided at the center of the first connecting rod and the second connecting rod.

[0009] Furthermore, mounting shafts are provided at the connection points between the top and bottom of the first connecting rod and the second connecting rod.

[0010] Furthermore, a support rod is extended from one end of the installation shaft, and a receiving groove is opened on one side of the support rod.

[0012] Furthermore, a storage groove is arranged on the top of the workbench, a soft cushion is arranged on the inner side of the storage groove, and a baffle is installed on the outer side of the storage groove.

DETAILED DESCRIPTION

[0023] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0024] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0025] like Figure 1 As shown, the present application provides a material tensile testing device, including a workbench 1, which is arranged in a material processing plant. A testing component 2 is arranged on the workbench 1, and the testing component 2 is used to perform a tensile test on the material, so that the staff can quickly evaluate the strength and ductility of the material.

[0026] The test assembly 2 includes a fixing frame 21, which is fixedly mounted on the top of the workbench 1. A hanging rod 22 is fixedly mounted on the top of the fixing frame 21. The hanging rod 22 is provided with multiple groups of notches 221. A clamping assembly 3 is hung in the notch 221. The clamping assembly 3 is used to perform a tensile test on the material to be tested.

[0027] like Figure 2-Figure 4 As shown, the clamping assembly 3 includes a first connecting rod 31, a rotating shaft 311 is arranged at the center of the first connecting rod 31, so that the first connecting rod 31 is suitable for rotating around the rotating shaft 311, and a second connecting rod 32 is arranged on one side of the first connecting rod 31, the second connecting rod 32 has the same structure as the first connecting rod 31, and both ends of the second connecting rod 32 are rotatably connected to both ends of the first connecting rod 31, so that the first connecting rod 31 and the second connecting rod 32 form a rectangular frame;

[0028] At the same time, a mounting shaft 33 is provided at the connection between the top and the bottom of the first connecting rod 31 and the second connecting rod 32, so that the first connecting rod 31 and the second connecting rod 32 are suitable for rotating around the mounting shaft 33. At the same time, a hook 34 is rotatably connected in the mounting shaft 33 at the top. The size of the hook 34 is adapted to the size of the notch 221, so that the rectangular frame is suitable for being hung on the hanging rod 22 under the cooperation of the hook 34 and the notch 221.

[0029] At the same time, a connecting rod 35 is extended from the bottom of the first connecting rod 31 and the second connecting rod 32, and a clamping block 5 is fixedly provided at the bottom of the connecting rod 35, and a locking tooth 51 is provided on the inner side of the clamping block 5. When the first connecting rod 31 and the second connecting rod 32 form a rectangular frame, the locking teeth 51 in the two groups of clamping blocks 5 will engage with each other, so that the two groups of clamping blocks 5 can clamp the material.

[0030] At the same time, an elastic component 4 is also arranged in the rectangular frame, and the elastic component 4 includes two groups of hooking parts 41, and the two groups of hooking parts 41 are respectively installed on the inner sides of the first connecting rod 31 and the second connecting rod 32, and a spring 42 is hung between the two groups of hooking parts 41, and the spring 42 is used to keep the two groups of clamping blocks 5 in contact, so that the material can be firmly clamped and not fall off.

[0031] In order to facilitate the opening and closing of the clamping block 5, a support rod 6 is extended from one end of the installation shaft 33, and a receiving groove 61 is opened on one side of the support rod 6, which is convenient for the staff's fingers to be inserted. When the material to be tested needs to be clamped between the two groups of clamping blocks 5, the staff can control the two groups of support rods 6 to approach each other, thereby making the first connecting rod 31 and the second connecting rod 32 rotate around the installation shaft 33. At this time, the two groups of clamping blocks 5 located at the bottom of the first connecting rod 31 and the second connecting rod 32 will move away from each other, thereby driving the spring 42 to undergo elastic deformation. At this time, the material can be placed between the two groups of clamping blocks 5, and then the support rod 6 is loosened, the spring 42 is restored, and the two groups of clamping blocks 5 are re-clamped, thereby completing the fixation of the material.

[0032] When the material needs to be tested, first, the two ends of the material are respectively loaded into the two groups of clamping components 3, and then the first group of clamping components 3 is hung on the hanging rod 22, and the hook 34 on the second group of clamping components 3 is set toward the workbench 1. At this time, weights are installed on the hooks 34 of the second group of clamping components 3, so that the material is deformed under the drive of the weights. At this time, the deformation length of the material can be recorded, and because there are multiple groups of notches 221 on the hanging rod 22, multiple groups of materials can be tensile tested simultaneously on the fixed frame 21, and the load applied to the material can be controlled by adjusting the weight of the weight, which is convenient for the experimenter to adjust and control.

[0033] like Figure 1As shown, a storage groove 11 is also provided on the top of the workbench 1, and a soft pad is provided on the inner side of the storage groove 11. At the same time, a baffle is installed on the outer side of the storage groove 11. The storage groove 11 is used to protect the clamping assembly 3 to prevent the material from breaking during the test and causing the weight to fall out of the workbench 1, thereby causing damage to the clamping assembly 3, etc., so that it can effectively protect the stability of the clamping assembly 3 and the test process, ensuring the safety of the experiment.

[0034] In summary, the device is equipped with a clamping assembly 3 and a hanging rod 22, so that the device can perform tensile tests on multiple groups of materials at the same time, which not only improves the test efficiency, but also can accurately record and compare the deformation behaviors of different materials under the same conditions, which is conducive to the comparison and analysis of material properties under the same conditions and improves the reliability of test data.

[0035] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
