Description

Technical Field

[0001] This utility model relates to the field of garment production testing technology, specifically a tear testing device for garment strength testing. Background Technology

[0002] Clothing strength testing is an important part of evaluating clothing quality. It aims to determine the ability of clothing to withstand external forces, covering multiple aspects such as tensile strength, tear strength, and bursting strength. Through professional equipment, it simulates actual wearing stress scenarios to obtain accurate data to judge the durability of clothing. The tear test device used for strength testing is mainly used to determine the ability of clothing fabrics to resist tearing.

[0003] Existing garment strength tests typically involve using hooks on both sides to pull and tear the fabric seams. However, this type of test only considers the test effect of a single case, namely the force required to tear the seam when it is hooked by a hook of a single shape. It cannot simulate multiple shapes, thus leading to unreliable tear test results. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a tear testing device for clothing strength testing. It has the advantage of being able to conveniently and effectively test for various situations, solving the problem that existing clothing strength tests typically use hooks on both sides to pull and tear the fabric seams. However, this type of test only considers the testing effect of a single situation, that is, the force required to tear when the seam is hooked by a hook of a single shape. It cannot simulate multiple shapes, thus leading to the problem that the tear test results are not rigorous enough.

[0006] (II) Technical Solution

[0007] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A tear testing device for clothing strength testing includes a testing frame, a testing groove is provided on the outside of the testing frame, a connecting rod extending to the outside of the testing groove is provided on the inner wall of the testing groove, a limiting support corresponding to the position of the testing groove is fixedly installed on the outside of the testing frame, a tear claw extending into the inside of the testing groove and connected to the limiting support to form support is sleeved on the outside of the connecting rod, a tear simulation component extending to the outside of the testing frame is fixedly provided inside the testing frame, the outside of the tear simulation component is connected to the clothing and the sewn part of the clothing is hung at the tear claw, and an auxiliary limiting component for auxiliary positioning of the tear claw is provided inside the limiting support.

[0008] Based on the above technical solution, the present invention can be further improved as follows.

[0009] Furthermore, the end of the tearing claw is provided with a bending angle opposite to that of the tearing simulation component, and the outside of the tearing claw is provided with a foolproof support block that extends to the inside of the limiting support component and is connected to the auxiliary limiting component.

[0010] Furthermore, the auxiliary limiting member includes an elastic sheet fixed inside the limiting support member, and the other end of the elastic sheet is provided with a locking metal ball that slides inside the auxiliary limiting member and extends into the inside of the foolproof support block.

[0011] Furthermore, the tear simulation component includes a power component fixed inside the testing frame, with a pressure sensor for detecting tearing force fixedly connected to one end of the power component, and a wearable simulation component extending to and slidably connected to the other end of the pressure sensor.

[0012] Furthermore, the wearable simulation component is bent, and the bending point of the wearable simulation component corresponds to the end position of the tearing claw. The inside of the detection frame is provided with a sliding groove, and the ends of the power component and the wearable simulation component are both located inside the sliding groove. The wearable simulation component is connected to the detection frame through the sliding groove and forms a movement direction restriction.

[0013] This invention provides a tear testing device for clothing strength testing. By setting a tear simulation component, when a tear test is needed at the seam, the prepared garment can be placed over the wear simulation component, and the power component is controlled to return to its original position. At this time, the seam is placed at the tear claw to form a connection. Then, the power component can be activated to push the wear simulation component to begin tearing. At this time, the force can be recorded by a pressure sensor to know the tensile force required for tearing. After the tear claw test is completed, the tear claw can be pulled directly to squeeze the auxiliary limiting component and allow the anti-foolproof support block to detach, so that the tear claw can be directly removed. At this time, tear claws of different shapes can be replaced to conduct tear strength tests on clothing under different conditions. When the tear claw is installed, the anti-foolproof support block can work with the limiting support component to provide effective support. At the same time, the anti-foolproof support block can also guide the user to connect, which has the advantage of conveniently conducting effective tests for various conditions.

[0018] 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.

[0019] Please see Figure 1-3 This utility model provides a tear testing device for testing the strength of clothing, including a testing frame 1, a testing groove 2 on the outside of the testing frame 1, a connecting rod 3 extending to the outside of the inner wall of the testing groove 2, a limiting support 4 corresponding to the position of the testing groove 2 fixedly installed on the outside of the testing frame 1, a tear claw 5 extending into the inside of the testing groove 2 and connected to the limiting support 4 to form support on the outside of the connecting rod 3, a tear simulation element 6 extending to the outside of the testing frame 1 fixedly installed inside the testing frame 1, the outside of the tear simulation element 6 connecting to the clothing and hanging the sewn part of the clothing at the tear claw 5, and an auxiliary limiting element 7 for auxiliary positioning of the tear claw 5 inside the limiting support 4.

[0020] Furthermore, the end of the tearing claw 5 is provided with a bending angle opposite to that of the tearing simulation element 6, and the outside of the tearing claw 5 is provided with a foolproof support block that extends to the inside of the limiting support element 4 and is connected to the auxiliary limiting element 7.

[0021] The foolproof support block is a rectangular boss that is embedded in the guide groove of the limiting support 4 to ensure unique installation. Through the reverse bending angle design, it simulates the actual working condition of clothing being torn. The foolproof support block structure improves the clamping efficiency of the device.

[0022] Furthermore, the auxiliary limiting member 7 includes an elastic sheet fixed inside the limiting support member 4, and the other end of the elastic sheet is provided with a locking metal ball that slides inside the auxiliary limiting member 7 and extends into the inside of the foolproof support block.

[0023] The combination of elastic sheet and metal ball locking mechanism provides stable mechanical self-locking force and avoids claw displacement during testing.

[0024] Furthermore, the tear simulation component 6 includes a power component 61 fixed inside the testing frame 1. A pressure sensor 62 for detecting tearing force is fixedly connected to one end of the power component 61, and a wearable simulation component 63 extending to and slidably connected to the other end of the pressure sensor 62 extends to the outside of the testing frame 1.

[0025] The power component 61 can be either a hydraulic rod or an electric push rod;

[0026] By using pressure sensors to support the wearable simulator 63, the tearing force can be easily recorded during the tearing process, making it convenient to record the tear threshold in the current state.

[0027] Furthermore, the wearable simulation component 63 is bent, and the bending point of the wearable simulation component 63 corresponds to the end position of the tearing claw 5. The inside of the detection frame 1 is provided with a sliding groove, and the ends of the power component 61 and the wearable simulation component 63 are both located inside the sliding groove. The wearable simulation component 63 is connected to the detection frame 1 through the sliding groove and forms a movement direction restriction.

[0028] The bending angle matches the range of motion of the human elbow joint, and the linear guide rail is embedded in the sliding groove. Through the biomimetic bending design and the rigid guidance of the sliding groove, the fitting degree of the test path can be improved, which is more in line with the real use scenario than the traditional linear tensile test.
