Description

Technical Field

[0001] The utility model relates to the field of braided mesh tube testing, in particular to a braided mesh tube tensile testing device. Background Art

[0002] Most braided network tubes are made of PET material, which has good wear resistance, expandability, smoothness, flame retardancy, and air permeability and heat dissipation. They can protect internal cables, wire harnesses, optical cables, etc. during actual work.

[0003] In actual use, the diameter of the braided mesh tube itself is often expanded due to the problem of increasing the number of lights in the internal wiring harness. However, since the braided mesh tube itself has a certain degree of stretchability, it can also be expanded appropriately. However, the degree of stretchability that can be expanded is also limited. In addition, whether repeated stretching and long-term stretching will affect the quality of the braided mesh tube itself also requires special testing. Manual stretching cannot accurately grasp the stretching length, and durability testing is also impossible.

[0004] If there is a break during the stretching process, and there are too many products to be tested at the same time, you can use a camera to assist. At the same time, before and after stretching, especially after the test, you need to carefully observe whether the braided network tube is damaged, with the help of lights, magnifying glasses and other tools. Therefore, these tools are also available in the test device to complete the work in one stop, which is more convenient. Utility Model Content
