Description

Technical Field

[0001] This utility model relates to the field of outdoor jacket processing technology, specifically to a device for testing the tensile strength of outdoor jackets. Background Technology

[0002] As a common outdoor garment, the tensile properties of a waterproof jacket directly affect its comfort and durability. The maximum tensile strength of the fabric and seams must be adapted to the stretching deformation during human activity. If the tensile properties are insufficient, problems such as fabric tearing and seam cracking are likely to occur during outdoor activities. Therefore, tensile performance testing is a key link in the production and quality control of waterproof jackets.

[0003] Current equipment for testing the tensile properties of outdoor jackets has significant technical limitations: On the one hand, existing equipment mostly relies on static tensile testing structures, gradually applying tensile force and manually recording data. This not only results in long testing cycles but also data acquisition delays, making it difficult to quickly and accurately obtain the ultimate tensile force value during the stretching process, thus failing to meet the needs of efficient testing in mass production scenarios. On the other hand, existing equipment conducts tests in dry environments, failing to consider that outdoor jackets are easily soaked in sweat during outdoor use—sweat changes the physical properties of the fabric fibers, leading to a decrease in tensile performance. Test results in dry environments deviate significantly from actual usage scenarios, failing to accurately reflect the tensile performance of outdoor jackets under sweaty conditions, which can easily cause qualified products to experience tensile failures in actual use.

[0004] In summary, existing testing equipment cannot simultaneously achieve both "rapid and accurate measurement of ultimate tensile strength" and "simulated sweat-wet scenarios," making it difficult to meet the precise testing requirements for the tensile performance of outdoor jackets. Therefore, improvements are needed. Utility Model Content

[0014] Compared with the prior art, this utility model provides a device for testing the tensile strength of a rain jacket, which has the following advantages:

[0015] 1. This tensile strength testing device for rain jackets can quickly and accurately obtain the tensile limit value of rain jackets, solving the problems of lag and inaccurate data in existing equipment. The top clamping clamp (with a first spring) of the top clamping assembly and the bottom clamping clamp (with a cylinder and a second spring) of the bottom clamping assembly stably clamp the rain jacket to be tested from the top and bottom sides respectively. The hydraulic telescopic cylinder drives the sliding rod to move vertically along the slide groove in the gantry track, causing the top clamping assembly to pull the rain jacket upwards.

This tensile strength testing equipment for rain jackets can also simulate a sweaty environment to test the tensile performance of rain jackets, solving the problem of large discrepancies between dry environment testing and actual use. The motor of the scenario simulation mechanism drives the impeller inside the fan housing to rotate, while water pipes spray liquid onto the test area of ​​the rain jacket through nozzles to simulate sweat. The airflow generated by the impeller helps the liquid to evenly cover the surface of the rain jacket, making it reach a state similar to being sweaty. After the sweaty simulation is completed, the testing mechanism operates according to the above tensile testing principle, thus truly reflecting the tensile performance of the rain jacket under actual sweaty use scenarios and avoiding tensile failure of qualified products in actual use.

A hydraulic telescopic cylinder 41 is fixedly connected to the top middle of the sliding rod 43.

At the same time, the pressure sensor 44 is electrically connected to the display 47. When the pressure sensor 44 sends data to the display 47, the microcontroller processes the data and sends it to the display 47 for viewing.

[0031] The top clamping clip 453 of the top clamping assembly 45 (in conjunction with the first spring 454) and the bottom clamping clip 461 of the bottom clamping assembly 46 (in conjunction with the cylinder 462 and the second spring 463) stably clamp the part of the jacket to be tested from the top and bottom sides respectively. The hydraulic telescopic cylinder 41 drives the sliding rod 43 to move vertically along the slide groove in the gantry track 42, which drives the top clamping assembly 45 to pull the jacket upward. During the process, the pressure sensor 44 collects the tensile force data in real time and transmits the data to the display 47 synchronously. No manual recording is required. The ultimate tensile force value during the stretching process can be captured in real time to ensure efficient and accurate testing.

[0032] The gantry track 42 has grooves on both sides inside, and the sliding rod 43 extends into the grooves for sliding connection.

[0040] It can also simulate a sweaty environment to test the tensile performance of a rain jacket, solving the problem of large discrepancies between dry environment testing and actual use. The motor 51 of the scenario simulation mechanism 5 drives the impeller 52 inside the fan housing 53 to rotate, while the water pipe 54 sprays liquid onto the test area of ​​the rain jacket through the nozzle 55 to simulate sweat. The airflow generated by the impeller 52 can help the liquid evenly cover the surface of the rain jacket, making it reach a state similar to sweat. After the sweat simulation is completed, the testing mechanism 4 operates according to the above tensile testing principle, thereby truly reflecting the tensile performance of the rain jacket under actual sweaty use scenarios and avoiding tensile failure of qualified products in actual use.

[0041] In actual operation, when this device is used, it can quickly and accurately obtain the tensile limit value of the waterproof jacket, solving the problems of lag and inaccurate data in existing equipment. The top clamping clamp 453 of the top clamping assembly 45 (with the first spring 454) and the bottom clamping clamp 461 of the bottom clamping assembly 46 (with the cylinder 462 and the second spring 463) stably clamp the waterproof jacket to be tested from the top and bottom sides respectively; the hydraulic telescopic cylinder 41 drives the sliding rod 43 to move vertically along the slide groove in the gantry track 42, which drives the top clamping assembly 45 to stretch the waterproof jacket upward. During the process, the pressure sensor 44 collects the tensile force data in real time and transmits the data to the display 47 synchronously. There is no need for manual recording. It can capture the limit tensile force value in real time during the stretching process, ensuring efficient and accurate testing.

[0042] It can also simulate a sweaty environment to test the tensile performance of a rain jacket, solving the problem of large discrepancies between dry environment testing and actual use. The motor 51 of the scenario simulation mechanism 5 drives the impeller 52 inside the fan housing 53 to rotate, while the water pipe 54 sprays liquid onto the test area of ​​the rain jacket through the nozzle 55 to simulate sweat. The airflow generated by the impeller 52 can help the liquid evenly cover the surface of the rain jacket, making it reach a state similar to sweat.
