Description

Technical Field

[0001] The utility model relates to a tester, in particular to a waist belt fabric elasticity tester. Background Art

[0002] A lumbar support belt, also known as a waist corset, waist brace, waist support, or waist cinch, is an assistive device worn around the waist, primarily used to protect the waist, relieve lumbar pressure, and assist in rehabilitation. Modern lumbar support belts are typically made of breathable material, equipped with adjustable elastic bands, and built-in semi-rigid support strips such as aluminum alloy strips or medical fiber plastic strips to limit excessive lumbar movement. The purpose of elasticity testing of lumbar support belt fabrics is primarily to ensure that the support belts provide appropriate support, comfort, and functionality during use. Elasticity testing is a key step in the development and quality control of lumbar support belt fabrics, ensuring that the product meets safety and comfort standards while meeting user needs.

[0003] Existing fabric elasticity testers mainly use tensile testing to test the elasticity of fabrics. A single measurement method cannot accurately measure the stretchable length of the fabric at the same time. Manual length measurement is required after the test to accurately measure the different stretch lengths required by different groups of people.

[0004] Therefore, we propose a waist belt fabric elasticity tester that can accurately measure the stretchable length while measuring the elastic force. Utility Model Content

The rocker is rotatably connected to the right side of the outer frame, and the left end of the rocker extends into the inner right side of the outer frame. There are two bevel gears, one of which is rotatably connected to the left end of the rocker. The other bevel gear is rotatably connected to the inner bottom of the right side of the outer frame. The two bevel gears are engaged with each other. The top of one of the bevel gears on the inner bottom of the right side of the outer frame is rotatably connected to the first screw. A sliding sleeve is provided on the threaded sleeve of the first screw, and a connecting piece is fixedly connected to the sliding sleeve. The left side of the connecting piece is fixedly connected to the right side of the slider.

[0008] Preferably, the clamping mechanism includes a guide rod, a clamping block, a second screw and a knob.

[0021] Embodiment: A waist belt fabric elasticity tester, such as Figure 1-Figure 5 As shown, it includes a base 1, an outer frame 2, a stretching mechanism 3, a slider 4, a tension measuring instrument 5, a tape measure 6, a connecting block 7, a fixing rod 8 and a clamping mechanism 10. The top rear side of the base 1 is connected to the outer frame 2 by screws, and the right side of the outer frame 2 is provided with a stretching mechanism 3. A vertical slide groove is opened in the middle of the front side of the outer frame 2, and a slider 4 is provided in the slide groove of the outer frame 2. A tension measuring instrument 5 is fixedly installed on the front side of the slider 4 for measuring the force exerted on an object under tension. The middle position of the bottom of the tension measuring instrument 5 and the middle position of the top of the base 1 are both fixedly connected with a fixing rod 8. The fixing rods 8 at the two places are far away from each other, and the opposite ends of the fixing rods 8 at the two places are provided with a clamping mechanism 10. A tape measure 6 is fixedly connected to the right side of the tension measuring instrument 5, and the tape measure 6 is in a pulled-out state. A connecting block 7 is fixedly installed on the right side of the upper part of the base 1, and the bottom end of the tape measure 6 is fixedly connected to the top of the connecting block 7, so that the pulled-out part of the tape measure 6 is vertical.

[0022] like Figure 1-Figure 3 As shown, the stretching mechanism 3 includes a rocker 30, a bevel gear 31, a first screw 32, a sleeve 33 and a connecting piece 34. The rocker 30 is rotatably connected to the right side of the outer frame 2, and the left end of the rocker 30 extends into the inner right side of the outer frame 2. There are two bevel gears 31, one of which is rotatably connected to the left end of the rocker 30, and the other bevel gear 31 is rotatably connected to the bottom inner right side of the outer frame 2. The two bevel gears 31 are engaged with each other, and the top of one of the bevel gears 31 on the bottom inner right side of the outer frame 2 is rotatably connected to the first screw 32. A sleeve 33 is threadedly provided on the first screw 32, and a connecting piece 34 is fixedly connected to the sleeve 33. The left side of the connecting piece 34 is fixedly connected to the right side of the slider 4.

[0023] like Figure 1 、 Figure 3-Figure 5 As shown, the clamping mechanism 10 includes a guide rod 100, a clamping block 101, a second screw 102 and a knob 103. The bottom of the fixed rod 8 at the two places is fixedly connected to the guide rod 100, and clamping blocks 101 are slidably sleeved on the left and right sides of the middle of the guide rod 100. The lower part of the clamping block 101 is tilted, and the middle of the clamping blocks 101 on both sides are threadedly connected to the second screw 102, and the two ends of the second screw 102 are fixedly connected to the knob 103. The clamping surfaces of the clamping blocks 101 are all frosted materials with large friction, so that the fabric will not fall off easily.

[0024] like Figure 1 、 Figure 3 and Figure 5 As shown, a pointer 9 is also included. The pointer 9 is fixedly connected to the fixed rod 8 at the middle position of the bottom of the tension measuring instrument 5, and the pointer 9 extends horizontally to the front side of the tape measure 6. The tape measure 6 is a steel roll measuring ruler.

[0025] When the user uses this device to test the waist belt fabric, first, the sample fabric is passed through the gap between the two clamping blocks 101, and then the knob 103 on one side is turned clockwise. This knob 103 drives the second screw 102 to rotate, so that the two clamping blocks 101 are threadedly matched with the second screw 102 along the guide rod 100, and move similarly to clamp the sample fabric. After the clamping is completed, the rocker 30 is turned again, and the rocker 30 immediately drives the bevel gear 31 at its left end to rotate, so that the other bevel gear 31 meshing with it is driven to rotate. At the same time, the other bevel gear 31 is driven to rotate. And drive the first screw 32 to rotate. Under the rotation of the first screw 32, the sliding sleeve 33 cooperates with its thread and moves upward. When the sliding sleeve 33 moves upward, it will drive the slider 4 to move upward, and the fabric is pulled upward. At the same time, the slider 4 pulls out the tape measure 6, and the tension measuring instrument 5 measures the tension of the fabric at the same time. In the process of pulling the fabric, since the clamping surface of the clamping block 101 is made of frosted material, the fabric will not fall off easily. When the fabric is pulled to the limit and is completely taut, the result of the elasticity test can be obtained. At this time, turn the knob 103 counterclockwise again to loosen the clamped fabric and remove it;

[0026] After the fabric is removed, the movement of the slider 4 drives all the connected components at the same time, so that the pointer 9 also moves. Since the right end of the pointer 9 points to the scale of the measuring tape 6, the value indicated on the measuring tape 6 can be visually observed at this time, and then the fixed value can be subtracted to obtain the stretchable length of the fabric. When measuring the next fabric, the value of the tension measuring instrument 5 is reset to zero and the above steps are repeated.

[0027] Those skilled in the art should understand that the above embodiments do not limit the present invention in any form, and any technical solutions obtained by equivalent replacement or equivalent transformation fall within the protection scope of the present invention.
