[0002] Elastic yarn is a textile material with good stretch and recovery properties, widely used in clothing and fabrics requiring elasticity. During the production of elastic yarn, its elongation performance needs to be tested. However, existing testing devices are inconvenient for binding the yarn, leading to loosening after stretching and affecting the test results. Furthermore, while applying a fixed weight to the yarn during testing is necessary, the suspension method can cause center shift, affecting the accuracy of the test. Therefore, improvements to existing technologies are needed. Utility Model Content

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] 1. This utility model adds a clamping wheel, a rubber block, and a clamping groove inside the wheel frame.

[0019] Please see Figure 1 , Figure 2 , Figure 3 An elastic yarn elongation detection device includes a base 1, a frame 2 fixedly connected to the upper end of the base 1, a buffer mechanism 3 provided on the base 1, two symmetrically distributed guide rods 4 fixedly connected inside the frame 2, a sliding sleeve 5 slidably connected to the outer side of the guide rods 4, a tension frame 6 fixedly connected to the outer side of the sliding sleeve 5, and wheel frames 7 fixedly connected to the outer sides of both the frame 2 and the tension frame 6. A clamping wheel 10 is installed inside the wheel frame 7 through a bearing, a fixing frame 12 is fixedly connected to the outer side of the wheel frame 7, a guide rod nail 13 is fixedly connected to the upper end of the fixing frame 12, a connecting plate 14 is slidably connected to the outer side of the guide rod nail 13, a rubber block 15 is fixedly connected to the lower end of the connecting plate 14, and a spring 16 is provided on the outer side of the guide rod nail 13.

[0020] Please see Figure 1 , Figure 2 , Figure 3 The lower end of the tension frame 6 is fixedly connected to a connecting rod 8, and the lower end of the connecting rod 8 is fixedly connected to a carrying tray 9. The carrying tray 9 can be used to place weights. The outer side of the clamping wheel 10 is provided with a clamping groove 11. The rubber block 15 is slidably connected to the clamping groove 11. After the yarn is tied to the outer side of the clamping wheel 10, the yarn can be squeezed into the inside of the clamping groove 11 by the rubber block 15. One end of the spring 16 is fixedly connected to the connecting plate 14, and the other end of the spring 16 is fixedly connected to the guide rod nail 13. The spring 16 can apply downward pressure to the connecting plate 14 through its elastic force.

[0021] Please see Figure 1 , Figure 4 The buffer mechanism 3 includes a fixed cover 31, a buffer rod 32 is slidably connected inside the fixed cover 31, a buffer cover 33 is fixedly connected to the upper end of the buffer rod 32, a second spring 34 is provided on the outer side of the buffer rod 32, and a rubber plate 35 is fixedly connected to the lower end of the buffer rod 32. The rubber plate 35 can increase the resistance at one end of the buffer rod 32. The rubber plate 35 is slidably connected to the fixed cover 31. One end of the second spring 34 is fixedly connected to the fixed cover 31, and the other end of the second spring 34 is fixedly connected to the buffer cover 33. The second spring 34 can support the buffer cover 33 through its elastic force.

[0022] The specific implementation process of this utility model is as follows: When in use, pull the connecting plate 14 upward, the connecting plate 14 drives the rubber block 15 to move, and compresses the spring 16. Then, the yarn is wound around the outside of the clamping wheel 10. After the winding is completed, the connecting plate 14 is released, the spring 16 returns to its original position, and the spring 16 can use its elasticity to drive the rubber block 15 to squeeze the yarn into the clamping groove 11, thus completing the installation of the yarn.

[0023] Then, weights are placed inside the loading tray 9 in the order of testing. During the weight placement process, the tension frame 6 slides along the direction of the guide rod 4, which makes the force on the yarn more stable. At the same time, when the yarn reaches its limit and breaks, the loading tray 9 falls. When the loading tray 9 comes into contact with the buffer cover 33, the buffer cover 33 drives the rubber plate 35 to move through the buffer rod 32 and compresses the spring 34. During the movement, the rubber plate 35 can effectively avoid structural damage to the loading tray 9 through the friction between it and the fixed cover 31.
