AI Technical Summary
Traditional underwear tensile testing instruments can only measure the tensile force when stretched flat, and cannot simulate the circumferential tensile force when underwear is worn, thus having limitations.
Based on the traditional underwear tensile testing instrument, vertical bars, hanging rings, clamping bars, and clamping columns are added to clamp and support the underwear, enabling circular tensile testing to simulate the stress conditions when wearing underwear.
It enables flat and circular tensile tests on underwear, simulating the stress conditions when underwear is worn, improving the comprehensiveness and accuracy of the test, and helping underwear manufacturers to standardize production and unify product quality.

Abstract
Description
Technical Field
[0001] This utility model relates to the testing of underwear stretch, specifically the measurement of tensile force during stretching, and more specifically, an instrument for testing the tensile force of underwear stretch. Background Technology
[0002] Underwear tensile strength testers are playing an increasingly important role in the design and manufacture of underwear. When choosing underwear materials, consumers can use the tester to conduct tensile tests on different materials to select those that meet the tensile strength requirements, thus better satisfying consumers' demands for underwear quality. In addition, underwear manufacturers can also use the tester to test finished products, which helps to standardize product quality.
[0003] Traditional underwear tensile testing instruments use two clamps to hold the two ends of the fabric. By moving one of the clamps, the fabric is stretched and the magnitude of the tensile force is obtained. This type of underwear tensile testing instrument has limitations, namely, it can only be used to measure the tensile force when the fabric is stretched flat. Summary of the Invention
[0004] The purpose of this invention is to provide an underwear tensile testing instrument that can perform both flat stretch tests on underwear fabric and circular stretch tests on underwear.
[0005] Its objective is achieved through the following schemes:
[0006] An underwear tensile strength tester includes a base plate, a slider, guide rods, a lead screw nut, a support, a clamp, a tensile / compression sensor, a lead screw, and a motor. The motor, lead screw, and two guide rods are mounted on the base plate. The motor drives the lead screw to rotate within the lead screw nut, which can move left and right along the lead screw. The lead screw nut is fixed to the slider, allowing the slider to follow the lead screw nut and move left and right along the two guide rods. An adjustment plate is mounted on the base plate, and a clamp is fitted on the adjustment plate. The clamp and tensile / compression sensor are mounted on the slider. The slider is characterized by a vertical bar on the back of the clamp, with horizontally extending lifting rings mounted above and below the clamp. Material clamping bars can be installed on the upper and lower lifting rings. Material clamping posts are also mounted on the adjustment plate.
[0007] In this way, the bra can be clamped by the clamping plates and clamping blades to complete the tensile test of flat stretching, while the bra can be supported by the clamping rods and clamping columns to perform a circumferential stretching tensile test.
[0008] The underwear stretch tester invented in this invention only requires the addition of vertical bars, hanging rings, clamping bars and clamping columns to the original structure, so that the instrument can simultaneously perform circumferential stretching force tests on underwear, simulating the stretching force when underwear is worn. Moreover, its structural improvement is simple and conducive to its widespread application.
[0009] This utility model of an underwear tensile testing instrument can be used by underwear manufacturers to perform circumferential tensile tests on finished underwear. It also helps to standardize production, unify the quality of underwear, and make the products more in line with production standards. Attached Figure Description
[0010] Figure 1 This is a schematic diagram of the specific structure of a utility model underwear tensile testing instrument;
[0011] Figure 2 yes Figure 1 Enlarged view of section I in the middle. Detailed Implementation
[0012] The specific embodiments of the utility model will be further described in detail below with reference to the accompanying drawings:
[0013] Reference Figure 1 and Figure 2 The underwear tensile strength tester of this specific embodiment includes a base plate 1, a slider 2, guide rods 3, a lead screw nut 4, a support 5, a clamping blade 6, a tensile / compression sensor 7, an adjusting plate 8, a clamping plate 9, a lead screw 10, and a motor 11. The motor 11, the lead screw 10, and the two guide rods 3 are mounted on the base plate 1. The motor 11 drives the lead screw 10 to rotate within the lead screw nut 4. The lead screw nut 4 can move left or right along the lead screw 10. The lead screw nut 4 is fixed to the slider 2. The slider 2 can move left or right along the two guide rods 3 following the lead screw nut 4. An adjustment plate 8 is installed on the base plate 1, and a clamping plate 9 is mounted on the adjustment plate 8. The clamping knife 6 and the tension and pressure sensor 7 are mounted on the slider 2. A vertical bar 12 is installed on the slider 2 on the back of the clamping knife 6. The vertical bar 12 is equipped with horizontally extending lifting rings 13 and 14 at the upper and lower positions of the clamping knife 6, respectively. The upper and lower lifting rings 13 and 14 can be used to install material clamping bars 15. A material clamping column 16 is also installed on the adjustment plate 8.
[0014] Thus, when performing a flat stretching test, the clamping plate 9 and clamping blade 6 can be held at both ends of the underwear. The motor 11 drives the lead screw 10 to rotate in the lead screw nut 4. The lead screw nut 4 drives the slider 2 to move to the right along the two guide rods 3, stretching the underwear. The corresponding tensile force can be obtained from the tension and pressure sensor according to the degree of stretching. When performing a ring stretching test, the clamping post 16 can be installed on the adjusting plate 8, and the clamping rod 15 can be installed between the upper and lower hanging rings 13 and 14. The clamping post 16 and clamping rod 15 can support the underwear from the inside. The motor 11 drives the lead screw 10 to rotate in the lead screw nut 4. The lead screw nut 4 drives the slider 2 to move to the right along the two guide rods 3, stretching the underwear. The corresponding tensile force of the ring stretching can be obtained from the tension and pressure sensor according to the degree of stretching.
