Description

Technical Field

[0001] The utility model relates to the technical field of stretching testing equipment, in particular to a stretching testing device used in socks production. Background Art

[0002] After the production of the same batch of socks is completed, a random inspection will be carried out on the current batch of socks to check the appearance and knitting quality of the socks. In addition, by testing the stretch performance of the socks at different degrees, its quality and durability can also be evaluated.

[0003] Generally, when a sock is subjected to a tensile test, the sock is clamped between two clamps and then stretched at a certain speed. At the same time, the instrument will record the performance of the sock during the stretching process, such as the extension performance, the stretching recovery performance, etc., so as to reflect the extension performance and the stretching elastic recovery performance of the sock under low stress. For example, the Chinese utility model patent disclosed by the publication number CN218444865U: A sock stretching detection device, the application is provided with a fixing frame, a motor, a screw, a slider, a connecting rod, a spring, a handle, an insertion rod, a support rod, and a fixing rod. When in use, the user puts the sock on the support rod, the fixing rod, and the fixing rod. The outside of the rod is then driven by a motor to rotate the screw, the rotation of the screw drives the slider to move through the connecting rod, the movement of the slider drives the support rod to move, the movement of the support rod will stretch the socks, and the user can then perform a stretching test on the socks. Since the application is through the support rod and the outside of the fixed rod, a stretching test of the sock opening is achieved. However, when a whole stretch test is performed on the socks, the support rod and the fixed rod cannot fix the two ends of the socks and perform a stretching test. At the same time, the application only provides conditions for replacing the support rod. Therefore, even if the support rod is replaced, the fixed rod cannot clamp one end of the sock.

[0024] like Figure 2-Figure 3 As shown, a connecting seat 11 is fixedly installed on the top of the clamp mounting frame 6, a sleeve 16 is fixedly installed on the top of the connecting seat 11, the connecting seat 11 is fixedly installed on the hydraulic cylinder 5, and the output end of the hydraulic cylinder 5 extends into the slide groove 7 through the sleeve 16 and the connecting seat 11, and the two displacement blocks 10 are respectively fixedly installed on the top, and a connecting block 13 is movably connected between the two fixing seats 12, and the center position of the connecting block 13 is fixedly connected to the output end of the hydraulic cylinder 5. The lifting and lowering of the connecting block 13 is controlled by the hydraulic cylinder 5, so that the connecting block 13 can cooperate with the two fixing seats 12 to drive the corresponding displacement blocks 10 to move up and down in the slide groove 7, and cooperate with the inclined surfaces on both sides of the slide groove 7, so that the two displacement blocks 10 can move synchronously relative to each other when moving downward;

[0025] like Figure 2-Figure 5As shown, the two displacement blocks 10 are respectively provided with mounting grooves 17 on opposite sides, and a rotation groove 18 is provided on the inner side of the mounting groove 17. A limiting groove 19 is provided on the inner side of the rotation groove 18. The longitudinal section of the limiting groove 19 is a regular hexagon. An end cover 20 is fixedly installed in the mounting groove 17. The end cover 20 does not have a through hole.
