Description

Technical Field

[0001] This utility model belongs to the field of testing equipment, and specifically relates to a fabric elasticity testing device. Background Technology

[0002] Fabric elasticity testing devices are used to test the elasticity properties of fabrics. Currently, some fabric elasticity testing devices struggle to apply stress evenly to the fabric during testing. This is mainly due to the imprecise design of the device's clamping structure. For example, some testing devices use simple pressure plates or clamps to fix the fabric, resulting in differences in force transmission between the fabric's edges and center. When tension or pressure is applied to the fabric, this can easily lead to localized stress concentration, thus affecting the accuracy of the test results.

[0003] Conventional solutions involve improving the clamping structure, such as using multi-point fixation or adding cushioning materials. However, this approach has drawbacks. Multi-point fixation increases the complexity of fabric fixation and may cause uneven pre-deformation of the fabric during the fixation process. Therefore, a new structure is needed to address these technical problems. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a fabric elasticity testing device to solve the problems mentioned in the background art.

[0005] This utility model is achieved through the following technical solution: a fabric elasticity testing device, comprising: a testing component, the testing component being installed on the outer surface of a support assembly for testing the elasticity of the fabric, the support assembly including support rods for mounting fixed frames, the fixed frames being provided in three configurations, the testing component including a mounting plate for mounting a first testing component, and a second testing component being installed on the outer surface of the two support rods on the left and right sides respectively.

[0006] In a preferred embodiment, four support rods are provided, all four support rods have the same structure, three fixing frames have the same structure, three fixing frames are installed between the four support rods, and an installation plate is installed inside the uppermost fixing frame.

[0007] In a preferred embodiment, the detection component includes an electric push rod and a detection head. Two electric push rods are symmetrically mounted on the lower surface of the mounting plate, and the telescopic rods of the electric push rods penetrate the mounting plate.

[0008] In a preferred embodiment, the telescopic rod of the electric push rod is equipped with a detection head. The detection head has a bullet-shaped structure and is made of rubber. The second detection component includes a bearing, a roller, and a short rod. In use, the detection head, together with the electric push rod and the first detection component, can directly contact the fabric and accurately measure the deformation of the fabric after being subjected to external force, making it convenient for users to observe and record.

[0009] In a preferred embodiment, two bearing components are symmetrically installed on the left side surfaces of the two left-side support rods, and two bearing components are symmetrically installed on the right side surfaces of the two right-side support rods. A roller is rotatably installed between the two bearing components. During use, the roller contacts the fabric in a surface contact manner. When testing the fabric elasticity, the testing force (the force generated when the roller rotates) can be evenly applied to the fabric, avoiding local stress concentration and making the fabric more uniformly stressed. This more accurately reflects the true elastic performance of the fabric and reduces testing deviations caused by uneven stress.

[0010] In a preferred embodiment, a motor is mounted on the rear surface of the roller via a bearing to drive the roller to rotate, and two short rods are symmetrically mounted on the outer surface of the roller.

[0011] In a preferred embodiment, the short rod is made of rubber, and the fabric is fixed to the outer surface of the roller by the short rod. The fabric is fixed above the mounting plate by two detection elements.

[0012] After adopting the above technical solution, the beneficial effects of this utility model are as follows: By setting up a detection component, which includes an electric push rod and a detection head, two electric push rods are symmetrically installed on the lower surface of the mounting plate. The telescopic rod of the electric push rod passes through the mounting plate. When in use, the contact between the roller and the fabric is a surface contact. When detecting the elasticity of the fabric, the detection force (the force generated when the roller rotates) can be evenly applied to the fabric, avoiding local stress concentration and making the fabric more uniformly stressed. This more accurately reflects the true elastic performance of the fabric and reduces the detection deviation caused by uneven stress.

[0013] By setting up detection component two, a detection component two is installed on the outer surface of the two support rods on the left and right sides respectively. Detection component two includes a bearing, a roller and a short rod. When in use, the detection head, together with the electric push rod and detection component one, can be directly used as a part that comes into direct contact with the fabric. It can accurately measure the deformation of the fabric after being subjected to external force, which is convenient for users to observe and record. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1 to 2 This utility model provides a technical solution: a fabric elasticity testing device, comprising: a testing component, the testing component being installed on the outer surface of a support component for testing the elasticity of the fabric, the support component including a support rod 100 for mounting a fixing frame 110, three fixing frames 110 being provided, the testing component including a mounting plate 120 for mounting a first testing component, and a second testing component being installed on the outer surface of the two support rods 100 on the left and right sides respectively.

[0022] Please see Figures 1 to 2 As the first embodiment of this utility model: four support rods 100 are provided, the four support rods 100 have the same structure, the three fixing frames 110 have the same structure, the three fixing frames 110 are installed between the four support rods 100, and the mounting plate 120 is installed inside the uppermost fixing frame 110.

[0023] The first test component includes an electric push rod 200 and a test head 210. Two electric push rods 200 are symmetrically installed on the lower surface of the mounting plate 120, and the telescopic rod of the electric push rod 200 passes through the mounting plate 120.

[0024] The telescopic rod of the electric push rod 200 is equipped with a detection head 210. The detection head 210 has a bullet-shaped structure and is made of rubber. The detection component 2 includes a bearing component 300, a roller 310, and a short rod 320.

[0025] In use, the user first prepares the fabric to be tested, then fixes both sides of the fabric to the surface of the second detection element on the outside of the support rod 100. After fixing the fabric, the user can stretch the fabric to a certain extent using the second detection element, but not fully stretch it to a taut state. After the fixed fabric is taut, the user can activate the electric push rod 200 on the lower surface of the mounting plate 120, causing the telescopic rod of the electric push rod 200 to extend, which in turn drives the detection head 210 connected to the telescopic rod to rise, thereby squeezing and piercing the fabric. At this time, the user can observe the state of the fabric being squeezed by the detection head 210, thereby observing the elasticity of the fabric. Regarding elasticity tolerance, users can select different types and shapes of detection heads 210 according to different fabric characteristics and testing requirements during actual use. For smooth fabrics, a flat detection head 210 can be used to ensure full contact with the fabric and accurately measure its elasticity. For fabrics with textures or uneven structures, a specially designed detection head 210 with grooves or protrusions can be used to better fit the fabric surface and improve the accuracy of the test. Since the detection head 210, together with the electric push rod 200 and the test piece, can be used as a component that directly contacts the fabric, it can accurately measure the deformation of the fabric after being subjected to external force, making it convenient for users to observe and record.

[0026] Please see Figures 1 to 2 As a second embodiment of this utility model: two bearing components 300 are symmetrically installed on the left side surface of the two left support rods 100 respectively, and two bearing components 300 are symmetrically installed on the right side surface of the two right support rods 100 respectively. A roller 310 is rotatably installed between the two bearing components 300.

[0027] A motor is mounted on the rear surface of roller 310 via bearing 300 to drive roller 310 to rotate, and two short rods 320 are symmetrically mounted on the outer surface of roller 310.

[0028] The short rod 320 is made of rubber. The fabric is fixed to the outer surface of the roller 310 by the short rod 320. The fabric is fixed above the mounting plate 120 by two detection pieces.

[0029] In use, when fixing the fabric using the steps of the first embodiment, firstly, one side of the fabric is fixed to the outer surface of the roller 310 by piercing it with the short rod 320. Then, the other side of the fabric is fixed using the same principle. After both sides of the fabric are fixed, the user can start the motor on its rear surface (the motor is a forward and reverse motor, and its model can be any existing model on the market; the specific working principle and structure are not described here), causing the roller 310 on the left side of the left support rod 100 to rotate counterclockwise, and causing the roller 310 on the right side of the right support rod 100 to rotate counterclockwise. The roller 310 rotates clockwise, generating tension to perform a tensile test on the fabric fixed between the roller and the fabric, thus detecting the elasticity of the fixed fabric. After the test is completed, the user can remove the fabric by reversing the above steps. Since the contact between the roller 310 and the fabric is surface contact, the testing force (the force generated when the roller 310 rotates) can be evenly applied to the fabric when testing the fabric elasticity, avoiding local stress concentration and making the stress on the fabric more uniform. This more accurately reflects the true elastic performance of the fabric and reduces the testing deviation caused by uneven stress.

[0030] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
