Description

Technical Field

[0001] This utility model relates to the field of elasticity testing technology for lightweight elastic fiber underwear, specifically an elasticity testing device for lightweight elastic fiber underwear. Background Technology

[0002] In utility model patent application CN116499889A, published on July 28, 2023, entitled "A Fabric Elasticity Testing Device," this invention discloses a fabric elasticity testing device, including a machine body and a fixed clamp and a movable clamp connected to the machine body. The machine body is equipped with a scale. The movable clamp is connected to a load-bearing water tank, which includes an outer shell and an inner sleeve. A weighing device is located at the bottom of the outer shell, and the weight of the inner sleeve is weighed using the weighing device. The inner sleeve has a water inlet and a water outlet. During the testing process, the load on the fabric is adjusted by adding or draining water from the load-bearing water tank, and the fabric elasticity under different loads is tested. This invention uses a load-bearing water tank instead of existing weights. The load-bearing water tank can be filled with water, and by adding different amounts of water, the load provided to the fabric can be arbitrarily adjusted, achieving the purpose of testing the fabric elongation and deformation rate under different loads. The test data and results are more accurate and reliable, overcoming the limitations of existing elasticity testing methods.

[0003] In the prior art, including the aforementioned patents, the testing of lightweight elastic fiber underwear fabrics on the market often involves using a clamping frame to hold and stretch the fabric from above, and then manually marking it with a marker pen. However, because lightweight elastic fiber underwear has high elasticity, the accuracy of the data is affected by the rebound force after stretching. Therefore, during different tensile force tests, it is necessary to repeatedly record the distance results, which is cumbersome and makes it difficult to intuitively compare the results before and after. Therefore, it is necessary to design an elasticity testing device for lightweight elastic fiber underwear that reduces the impact of rebound. Utility Model Content

[0004] The purpose of this invention is to provide an elasticity testing device for lightweight elastic fiber underwear, in order to solve the problem mentioned in the background art where the elastic fabric rebounds during the testing process, affecting the accuracy of the measurement.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an elasticity testing device for lightweight elastic fiber underwear, comprising a base, a frame fixedly connected to the top of the base, a top seat fixedly connected to the top of the frame, an adjusting cylinder installed at the bottom of the top seat, an upper clamping assembly fixedly connected to the output end of the adjusting cylinder, a marking assembly fixedly connected to the outer wall of the upper clamping assembly, a drop clamping assembly installed on the top of the base, and a control host installed on the outer wall of the frame.

[0006] Furthermore, the upper clamping assembly includes a clamping seat, a threaded fixing rod, and an anti-detachment plate. The output end of the adjusting cylinder is fixedly connected to the clamping seat, the outer wall of the clamping seat is threadedly connected to the threaded fixing rod, and one end of the threaded fixing rod is fixedly connected to the anti-detachment plate.

[0007] Furthermore, the anti-detachment plate is located inside the clamping seat, and the upper clamping assembly is located above the lower clamping assembly.

[0008] Furthermore, the marking assembly includes a marking scale plate, a telescopic frame, marking pins, and a sliding groove. The marking scale plate is fixedly connected to the back of the clamping base. The front of the marking scale plate has a sliding groove. The telescopic frame is slidably mounted on the front of the marking scale plate through the sliding groove. The marking pins are fixedly connected to the front of the telescopic frame.

[0009] Furthermore, the marking pin is located at the central axis of the telescopic frame, and the back of the telescopic frame is connected to the slide groove via a slider, and the front of the marking scale plate is provided with scale lines.

[0010] Furthermore, the interior of the drop clamping assembly includes a telescopic rod, a drop seat, a pin, a weight pan, and a socket. The top of the base is fixedly connected to the telescopic rod, and one end of the telescopic rod is fixedly connected to the drop seat. The outer wall of the drop seat has a socket, through which a pin is inserted. The front of the drop seat is fitted with a weight pan.

[0011] Furthermore, the compression distance of the telescopic rod is equal to the extension distance of the telescopic frame, and the drop seat is located directly below the upper clamping assembly.

[0012] Compared with the prior art, the beneficial effects of this utility model are: the elasticity detection device for lightweight elastic fiber underwear is reasonable and has the following advantages:

[0013] (1) By using the marking component to mark the fabric of lightweight elastic fiber underwear that needs to be tested, the marking pins designed on the marking component can be used to fix the positions at the same distance. By using the fixing of the telescopic frame, the length of the fabric after it is straightened can be intuitively displayed. The stretching distance can be directly displayed by the telescopic frame, reducing the impact of the elastic fabric rebound during the elasticity test, which makes it difficult to record the distance before rebound in time. The telescopic frame can be used to intuitively compare the distance before and after rebound and directly calculate it. The marking pin helps to ensure the consistency and repeatability of the test, so that each test is carried out at the same point, thereby improving the accuracy of the test results, making it easier to track the changes of the fabric in different test cycles, and facilitating the comparison of the long-term performance of the fabric elasticity.

[0014] (2) Through the upper and lower clamping structure design, it is easy to observe the changes in elasticity of lightweight elastic fiber underwear of different materials at different distances and under different tensions. By increasing the weight of the bottom drop, the weight is placed at the drop seat position to increase the gravity of the lower clamp, thereby increasing the tension. The rebound distance under different pressures is observed, which changes the experimental environment of the device, increases the diversity of fabric side observation, and makes the rebound test of the device more accurate.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 The present invention provides a technical solution as follows:

[0023] Example 1:

[0024] An elasticity testing device for lightweight elastic fiber underwear includes a base 1, a frame 2 fixedly connected to the top of the base 1, a top seat 3 fixedly connected to the top of the frame 2, an adjusting cylinder 4 installed at the bottom of the top seat 3, an upper clamping assembly 5 fixedly connected to the output end of the adjusting cylinder 4, a marking assembly 6 fixedly connected to the outer wall of the upper clamping assembly 5, a drop clamping assembly 7 installed on the top of the base 1, and a control host 8 installed on the outer wall of the frame 2.

[0025] The above structure uses the marking component 6 to mark the fabric of lightweight elastic fiber underwear that needs to be tested. The marking pins 603 designed on the marking component 6 can fix positions at the same distance. With the fixation of the telescopic frame 602, the length of the fabric after it is straightened can be intuitively displayed. The stretching distance is directly displayed by the telescopic frame 602, reducing the impact of the elastic fabric rebounding during the elasticity test.

[0026] Furthermore, the upper clamping assembly 5 includes a clamping seat 501, a threaded fixing rod 502, and an anti-detachment plate 503. The output end of the adjusting cylinder 4 is fixedly connected to the clamping seat 501. The outer wall of the clamping seat 501 is threadedly connected to the threaded fixing rod 502. One end of the threaded fixing rod 502 is fixedly connected to the anti-detachment plate 503. The anti-detachment plate 503 is located inside the clamping seat 501, and the upper clamping assembly 5 is located above the lower clamping assembly 7.

[0027] The above structure uses the upper clamping component 5 to fix the upper part of the underwear fabric, so that when the lower part is stretched, the upper part will not be subjected to force and fall off.

[0028] Furthermore, the marking assembly 6 includes a marking scale plate 601, a telescopic frame 602, a marking pin 603, and a slide groove 604. The marking scale plate 601 is fixedly connected to the back of the clamping base 501. The front of the marking scale plate 601 has a slide groove 604. The telescopic frame 602 is slidably mounted on the front of the marking scale plate 601 through the slide groove 604. The marking pin 603 is fixedly connected to the front of the telescopic frame 602. The marking pin 603 is located at the central axis of the telescopic frame 602. The back of the telescopic frame 602 is connected to the slide groove 604 through a slider. The front of the marking scale plate 601 is provided with scale lines.

[0029] The above structure allows for a direct comparison of the rebound distance using the telescopic frame 602, enabling direct calculation. The marking pin 603 helps ensure the consistency and repeatability of the test, ensuring that each test is conducted at the same point.

[0030] Furthermore, the interior of the drop clamping assembly 7 includes a telescopic rod 701, a drop seat 702, a pin 703, a weight pan 704, and a socket 705. The telescopic rod 701 is fixedly connected to the top of the base 1, and the drop seat 702 is fixedly connected to one end of the telescopic rod 701. The outer wall of the drop seat 702 has a socket 705, through which the pin 703 is inserted. The weight pan 704 is installed on the front of the drop seat 702. The compression distance of the telescopic rod 701 is equal to the extension distance of the telescopic frame 602. The drop seat 702 is located directly below the upper clamping assembly 5.

[0031] The aforementioned skull-dropping clamping component 7 facilitates increased pulling force by increasing gravity, thereby increasing the pulling force and rebound distance under different pressures.

[0032] Working principle: When in use, first, fix one end of the lightweight elastic fiber underwear fabric section prepared for testing at the position of the upper clamping component 5, that is, rotate the threaded fixing rod 502 so that the anti-slip plate 503 is squeezed inward. After cooperating with the clamping seat 501, one end of the fabric section is fixed, allowing the fabric to fall naturally, and the falling distance is recorded.

[0033] Next, after sewing the other end of the fabric section, cut a small hole and insert the pin 703 to fix it above the lower seat 702. The telescopic rod 701 is in the extended state at this time. The marking pins 603 are used to fix the fabric to the telescopic frame 602 in sequence. Weights are added to the weight pan 704, causing the lower seat 702 to fall under the force, thereby pulling up the fabric above. The telescopic frame 602 unfolds as the fabric is pulled up. The stretching distance of the telescopic frame 602 is recorded (the resistance of the telescopic frame 602 is negligible here). The marking pins 603 designed on the marking component 6 can fix the positions at the same distance. By fixing the telescopic frame 602, the stretching distance of the fabric after it is straightened can be visually displayed. The stretching distance can be directly displayed by the telescopic frame 602, reducing the impact of the elastic fabric rebound during the elasticity test, which makes it difficult to record the distance before rebound in time. The telescopic frame 602 can be used to visually compare the distance before and after rebound and directly calculate it.

[0034] Finally, the upper and lower clamping structure design facilitates side observation of the elasticity changes of lightweight elastic fiber underwear of different materials under different distances and different tensile forces. The adjusting cylinder 4 can drive the upper clamping component 5 to adjust the distance. By increasing the weight at the bottom, the weight is placed at the lower drop seat 702 position, increasing the gravity of the lower clamping, thereby increasing the tensile force. By observing the rebound distance under different pressures, the experimental environment of the device is changed, increasing the diversity of fabric side observation, and making the rebound test of the device more accurate.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
