A braided mesh tube tensile testing device

Abstract

This utility model discloses a tensile testing device for braided mesh tubes, including a main body with a working base. In use, the movable tension rod is first moved close to the fixed tension rod. The braided mesh tube is then fitted onto both the movable and fixed tension rods. Rotating the adjusting wheel drives the screw to rotate, which in turn causes the transmission slider to move the movable tension rod away from the fixed tension rod, thus stretching the braided mesh tube. The self-locking principle of the thread allows the movable tension rod to maintain this state. Multiple sets of fixed and movable tension rods can be used to simultaneously perform tensile tests on multiple braided mesh tubes. Furthermore, since both the fixed and movable tension rods are detachable, the corresponding tension rod can be replaced according to the size of the braided mesh tube being tested, improving the adaptability of the device.

Description

Technical Field

[0001] This utility model relates to the technical field of braided mesh tube testing equipment, specifically a braided mesh tube tensile testing device. Background Technology

[0002] Braided sleeving is mostly made of PET material and has good wear resistance, expandability, smoothness, flame retardancy and breathability. In actual work, it can protect internal cables, wire harnesses, optical cables, etc.

[0003] In practical use, the diameter of the braided mesh tube is often increased due to the need to add lights to the internal wiring harness. However, since the braided mesh tube itself has a certain degree of stretch, it can be appropriately expanded, but there is a limit to the degree of stretching. Furthermore, whether repeated stretching and long-term stretching will affect the quality of the braided mesh tube itself needs to be determined by special testing. Manual stretching cannot accurately control the stretching length, nor can it conduct durability tests.

[0004] Patent CN222299324U discloses a tensile testing device for braided mesh tubes, including a tensile assembly with multiple sets of components. Each assembly includes a tensile seat and tensile rods, with two symmetrically arranged tensile seats. Multiple sets of tensile rods are mounted on the tensile seats. The device also includes a worktable, multiple tensile devices, and an observation structure. Multiple tensile devices are mounted on the worktable, and tensile seats are respectively mounted on each device. The observation structure is located on the worktable and is used to observe the quality of the braided mesh tube before and after testing. This utility model relates to the field of braided mesh tube testing, specifically a tensile testing device for braided mesh tubes.

[0005] However, this device uses electromagnets and springs to move the sliding seat and stretch the braided mesh tube. Repeated stretching of the braided mesh tube requires repeated energizing of the electromagnet, which makes the structure prone to damage, and the device has high maintenance costs.

[0015] Preferably, the bottom of the main body of the device is provided with four support columns arranged in a matrix.

[0016] Compared with the prior art, this utility model provides a braided mesh tube tensile testing device with the following advantages: This utility model utilizes the cooperation of a screw, a transmission slider, a movable tension rod, and a fixed tension rod. During use, the movable tension rod is first moved close to the fixed tension rod. At this point, the braided mesh tube can be fitted onto the movable and fixed tension rods. Rotating the adjusting wheel drives the screw to rotate, and the threaded connection causes the transmission slider to move the movable tension rod away from the fixed tension rod, thus stretching the braided mesh tube. The self-locking principle of the thread allows the movable tension rod to maintain this state. Multiple sets of fixed and movable tension rods can simultaneously perform tensile tests on multiple braided mesh tubes. Furthermore, since both the fixed and movable tension rods are detachable, the corresponding tension rod can be replaced according to the size of the braided mesh tube being tested, improving the adaptability of the device.

The movable tension rod 5 can be kept in this state by the thread self-locking principle. Multiple sets of fixed tension rods 4 and movable tension rods 5 can be used to perform tensile tests on multiple braided mesh tubes at the same time. Since both the fixed tension rod 4 and the movable tension rod 5 are detachable structures, the corresponding tension rod can be replaced according to the size of the braided mesh tube to be tested, improving the adaptability of the device.

[0030] The connecting bolts 14 allow for quick assembly and disassembly of the plug rod 13 and the plug slot 12, thereby enabling quick assembly and disassembly of the movable tension rod 5.

The fixed seats 16 are provided with docking grooves. The bottom of the fixed tension rod 4 is provided with a docking block 8 that is adapted to the docking groove.
