Description

Technical Field

[0001] This utility model relates to the field of waterproof fabrics, and in particular to a device for testing the breathability of waterproof and breathable fabrics. Background Technology

[0002] Waterproof fabrics are specially treated textile materials that effectively prevent moisture penetration and keep fabrics dry. The breathability of waterproof and breathable fabrics is a key factor in evaluating their performance, especially crucial in the development and use of outdoor clothing and equipment. To accurately test the breathability of these fabrics, scientists and engineers use a variety of specialized testing equipment.

[0003] A search revealed Chinese Patent Publication No. CN219532851U, which discloses a device for testing the air permeability of polyester greige fabric. The device includes a chassis, a control console fixedly connected to the top of the chassis, a pressure rod fixedly connected to one side of the control console, an electric push rod fixedly connected to the top of the pressure rod, a limit ring fixedly connected to the output end of the electric push rod, a guide post movably connected to the top of the limit ring, a spring movably connected to the outer wall of the guide post, a pressure plate fixedly connected to one end of the spring, and an upper fixing ring movably connected to the bottom of the pressure plate. This device allows for tension adjustment when fixing the polyester greige fabric, enabling the fabric to expand and improving the testing effect and accuracy during air permeability testing. It avoids testing errors and ensures normal detection results due to low tension, further enhancing the practicality and ease of use of the testing device.

[0004] Because some fabrics are relatively lightweight, they are easily wrinkled or uneven due to external forces. This means that both the aforementioned devices and some existing traditional breathability testing equipment require manual maintenance to keep the fabric flat when placing it for testing. However, users also need to manually turn on and operate the equipment while testing the fabric. This makes it difficult for users to maintain the fabric flat while operating these devices, which is inconvenient and impractical. Therefore, a breathability testing device for waterproof and breathable fabrics is proposed to solve the above problems. Summary of the Invention

[0005] To overcome the above shortcomings, this utility model provides a breathability testing device for waterproof and breathable fabrics. It aims to improve the existing technology, which requires manually keeping the fabric flat when placing it for testing. However, users also need to manually turn on and operate the device when testing the fabric, which makes it difficult for users to keep the fabric flat while operating the device, which is quite inconvenient.

[0027] 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.

[0028] Reference Figure 1 - Figure 3This utility model provides an embodiment of a device for testing the breathability of waterproof and breathable fabrics, including a test platform 1 for testing the breathability of waterproof and breathable fabrics. A blowing device, airflow detection device, etc., can be installed in the middle of the platform to assist in the testing. This is prior art and will not be described in detail here. A bracket 4 is fixedly connected to the top surface of the test platform 1 for connecting various components. A fixing mechanism 2 is provided between the bracket 4 and the test platform 1 for fixing the fabric to assist in the testing. Two electric rods 3 are provided on the upper part of the fixing mechanism 2 for adjusting the position of the pressure plate 21 located at the top to assist in the breathability testing of the waterproof and breathable fabrics. The two electric rods 3 are fixedly connected to the bracket 4. A control panel 5 is provided in the middle of the bracket 4 for controlling the equipment in the test platform 1 and the electric rods 3, etc. This is prior art and will not be described in detail here.

[0029] Furthermore, the fixing mechanism 2 includes two pressure plates 21. The upper pressure plate 21 is fixedly connected to the electric rod 3, and the lower pressure plate 21 is fixedly connected to the test platform 1. A test port 211 is provided in the middle of the pressure plate 21 for testing the breathability of the waterproof and breathable fabric. Rubber rings 22 are provided on the sides of the two pressure plates 21 that are close to each other, which are used to fix the fabric. The rubber ring 22 of the upper pressure plate 21 protrudes from the upper pressure plate 21. Multiple flattening components 23 are provided at the lower part of the upper pressure plate 21 to help flatten the fabric. The lower part has multiple mounting grooves 212 for connecting various components. The top of the mounting groove 212 has a sliding groove 213 for connecting the slider 234. The two pressure plates 21 each have annular grooves 214 on their sides that are close to each other for connecting rubber rings 22. The rubber rings 22 are movably connected to the annular grooves 214. The two annular grooves 214 each have slots 215 on their sides that are far apart from each other. The two rubber rings 22 each have a retaining ring 221 fixedly connected to their sides that are far apart from each other. The retaining ring 221 is made of rubber and can deform to a certain degree of movement. The retaining ring 221 is movably connected to the slot 215.

[0030] Furthermore, the flattening assembly 23 includes a support rod 231, which is used to connect various components. The upper part of the support rod 231 is movably connected to the mounting groove 212, and the lower part of the support rod 231 is rotatably connected to a roller 232, which is used to cooperate with the movement of the lower part of the support rod 231 to flatten the fabric. The middle part of the support rod 231 is movably connected to two connecting rods 233, which are used to connect various components. The upper parts of the two connecting rods 233 are movably connected to a slider 234, which is used to cooperate with the movement of the upper part of the connecting rods 233. The slider 234 is slidably connected to the groove 213. The middle part of the slider 234 is slidably connected to a positioning rod 235, which is used to restrict the spring 236 to a certain extent to facilitate a smoother movement of the slider 234. The slider 234 and the mounting groove 212 are fixedly connected to a spring 236, which is used to cooperate with the movement and reset of the slider 234. The spring 236 is sleeved on the outside of the positioning rod 235.

[0031] Working principle: In use, first place the waterproof and breathable fabric to be tested on the lower pressure plate 21, then turn on the electric rod 3 to move the upper pressure plate 21 downward. At this time, the flattening component 23 connected to the upper pressure plate 21 will also be moved downward until the roller 232 contacts the fabric to be tested. As the upper pressure plate 21 continues to press down, under the pressure of the upper pressure plate 21, the upper end of the support rod 231 cannot move because it is connected to the mounting groove 212. Therefore, the lower end of the support rod 231 will drive the roller 232 to move outward. During the movement of the support rod 231, the connecting rod 233 connected to it will also be moved. The connecting rod 233 will push the slider 234 to compress the spring 236. Multiple rollers 232 will push the fabric outward from different directions, thus flattening the fabric until the electric rod 3 drives the upper rubber ring 22 to press against the lower rubber ring 22. Then, the breathability of the waterproof and breathable fabric can be tested through the test bench 1.

[0032] After the test is completed, simply move the pressure plate 21 and the flattening component 23 connected to it upwards using the electric rod 3. As the upper pressure plate 21 moves upwards, the flattening component 23 will gradually lose the force it applies, and the spring 236 will push the slider 234 to reset. The slider 234 will then drive the connecting rod 233 to reset, and the support rod 231 connected to the connecting rod 233 will be driven to reset. Then, the tested fabric can be removed from the lower pressure plate 21.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
