[0002] With the booming development of outdoor sports and tourism, and people's increasing pursuit of quality of life, the market demand for waterproof fabrics has shown a continuous growth trend. Waterproof fabrics are not only widely used in outdoor clothing, such as waterproof jackets, mountaineering clothes, and raincoats, providing reliable protection for people in harsh weather conditions; they also play a key role in outdoor equipment such as tents, sleeping bags, and backpacks, ensuring the comfort and safety of users outdoors.

[0003] Currently, some companies still use manual inspection to evaluate the performance of waterproof fabrics. Inspectors typically judge the waterproof effect by visually observing the fabric surface for defects, water seepage marks, etc., and by conducting simple spray or immersion tests. This makes it difficult to guarantee the accuracy of the inspection results. Utility Model Content

[0004] In view of this, the present invention aims to provide a waterproof fabric inspection device to solve the problems in the prior art.

[0005] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0010] Furthermore, a limiting ring is fixedly provided on the inner side wall of the upper cylinder, and a spraying assembly is provided inside the upper cylinder. The spraying assembly includes a receiving cover and a limiting edge. The limiting edge is fixedly provided on the upper periphery of the receiving cover, and the limiting edge is fixedly connected to the top of the limiting ring.

[0011] The bottom of the receiving cover has multiple perforations.

[0012] Furthermore, the end of the connecting pipe is also connected to a lower pipe that communicates with the upper cylinder, the upper pipe being located above the spray assembly and the lower pipe being located below the spray assembly;

[0013] The upper and lower pipes are respectively equipped with an upper valve and a lower valve.

[0014] Furthermore, clamping assemblies are symmetrically arranged on both sides of the inner hole on the top surface of the workbench. The clamping assembly includes an L-shaped mounting bracket fixedly connected to the top surface of the workbench and a plurality of telescopic columns slidably arranged on the mounting bracket. Springs are fitted on the telescopic columns, one end of which is fixedly connected to the mounting bracket and the other end is fixedly connected to the bottom of the telescopic column.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model in light of the specific circumstances.

[0033] The following will refer to the appendix. Figures 1 to 6 The present invention will be described in detail with reference to the embodiments.

[0034] Overall, this utility model relates to a waterproof fabric inspection device, including a workbench 1 with an internal cavity, a top plate 2 fixedly installed on the top of the workbench 1, an inner hole 201 opened at the center of the top plate 2, a fixing frame 3 symmetrically fixedly installed on both sides of the inner hole 201 on the top surface of the workbench 1, a fixing ring 301 fixedly installed between the fixing frames 3, an upper cylinder 4 slidably connected in the fixing ring 301, and a lower cylinder 5 connected below the upper cylinder 4, with a water outlet valve 501 provided on the lower cylinder 5;

[0035] The inner hole 201 has an inner groove 202 on its circumference. The bottom of the lower cylinder 5 is adapted to the inner groove 202. The upper cylinder 4 has an upper pipe 601 connected to its side wall. The upper pipe 601 is connected to external equipment through a connecting pipe 6.

[0036] In this embodiment, the bottom of the lower cylinder 5 is adapted to the inner groove 202 around the inner hole 201 of the top plate 2. During the test, the lower cylinder 5 squeezes the fabric into the inner groove 202, which can achieve precise fixation of the fabric and prevent the fabric from shifting or wrinkling during the stamping test, thus ensuring the accuracy and reliability of the test results.

[0037] The water outlet valve 501 installed on the lower cylinder 5 facilitates drainage. After the pressure test is completed, simply opening the water outlet valve 501 will quickly drain the water from the lower cylinder 5, preventing water accumulation inside the device, reducing corrosion and damage, extending the device's service life, and also facilitating subsequent cleaning and maintenance.

[0038] Specifically, operators only need to follow the prescribed steps to connect external equipment, place the fabric, control water flow and drainage, etc., to complete the inspection of waterproof fabrics. No complex operating skills or professional knowledge are required, reducing operational difficulty and labor intensity, and improving work efficiency.

[0039] In practice, first, place the waterproof fabric to be inspected flat on the top surface of the workbench 1, ensuring that the fabric covers the inner hole 201 in the center of the top plate 2. Then, check whether the connection of the connecting pipe 6 between the external equipment and the upper pipe 601 is secure, ensuring that the external equipment can supply water to the device normally.

[0040] In operation, the lower cylinder 4 slides downward within the fixing ring 301, causing the lower cylinder 5 to move downward as well. As the lower cylinder 5 descends, its bottom gradually contacts the fabric and squeezes the fabric into the inner groove 202 around the inner hole 201. When the lower cylinder 5 is fully inside the inner groove 202, the fabric is tightly fixed between the inner groove 202 and the lower cylinder 5.

[0041] The external equipment is activated, allowing water to enter the upper pipe 601 through the connecting pipe 6, and then flow into the upper cylinder 4. As water continues to flow in, the water level inside the upper cylinder 4 gradually rises, and the pressure exerted by the water on the fabric gradually increases. During this process, the operator can control the speed and flow rate of the water through the external equipment to simulate different water flow impact conditions. The water seepage of the fabric at the inner hole 201 is observed from below the top plate 2 to determine whether the waterproof performance of the fabric meets the standards.

[0042] Based on the above configuration, in order to ensure a more stable seal after the lower cylinder 5 enters the inner groove 202, in this embodiment, the inner sidewall of the bottom of the lower cylinder 5 is provided with a thread 503. During connection, the lower cylinder 5 is screwed to the inner groove 202 through the thread 503; the upper cylinder 4 is rotatably connected to the lower cylinder 5. A sealing gasket 502 is fixedly provided on the outer sidewall of the bottom of the lower cylinder 5.

[0043] It should be noted that, as Figure 3 As shown, the inner wall of the bottom of the cylinder is provided with threads 503, which allows it to be screwed into the inner groove 202. This connection method is more stable than the ordinary compression fit. During the test, even under the impact of large water pressure, the lower cylinder 5 is not easy to loosen or detach from the inner groove 202, ensuring stable fixation of the fabric. It can accurately simulate the fixation state of the fabric under actual use scenarios, providing a reliable guarantee for accurately evaluating the performance of waterproof fabrics.

[0044] Furthermore, the upper cylinder 4 and the lower cylinder 5 are rotatably connected, allowing the lower cylinder 5 to be screwed into the inner tank 202 without affecting the connection between the upper cylinder 4 and the external water supply equipment. A sealing gasket 502 is fixedly provided on the outer wall of the bottom of the lower cylinder 5. When screwed into the inner tank 202, the sealing gasket 502 can tightly fit the surface of the inner tank 202, preventing water leakage from the connection between the lower cylinder 5 and the inner tank 202.

[0045] It should be understood that fabric water resistance testing involves multiple indicators, such as the hydrostatic pressure test, which applies continuously increasing water pressure to one side of the fabric until a third water droplet appears on the other side, and records the pressure value at this point. Another indicator is the spray rating test, which involves spraying water from a certain height onto the fabric surface through a specific nozzle and observing the water seepage on the other side.

[0046] To meet the above-mentioned spray test standards, in this embodiment, as follows: Figure 3 As shown, a limiting ring 401 is fixedly provided on the inner side wall of the upper cylinder 4. A spray assembly is provided inside the upper cylinder 4. The spray assembly includes a receiving cover 9 and a limiting edge 901. The limiting edge 901 is fixedly provided on the upper periphery of the receiving cover 9. The limiting edge 901 is on the top of the limiting ring 401 and is fixedly connected to it. Multiple through holes 902 are provided at the bottom of the receiving cover 9.

[0047] In this invention, a limiting ring 401 is fixedly provided on the inner wall of the upper cylinder 4, and a limiting edge 901 on the receiving cover 9 can securely install the spray assembly at a specific position inside the upper cylinder 4. This precise positioning allows water introduced from the outside to enter the spray assembly through the upper cylinder 4 and form a stable and uniform spray water flow through multiple evenly distributed perforations 902 at the bottom of the receiving cover 9, precisely acting on the waterproof fabric to be tested below.

[0048] Furthermore, such as Figure 2 and Figure 3 As shown, the end of the connecting pipe 6 is also connected to a lower pipe 602 that is connected to the upper cylinder 4. The upper pipe 601 is located above the spray assembly, and the lower pipe 602 is located below the spray assembly. An upper valve 603 and a lower valve 604 are respectively provided on the upper pipe 601 and the lower pipe 602.

[0049] It should be noted that the upper pipe 601 and the lower pipe 602 are located above and below the spray assembly, respectively, and each pipe is equipped with an upper valve 603 and a lower valve 604. This design allows operators to control the opening and closing of the upper pipe 601 and the lower pipe 602 according to different testing needs. For example, when it is necessary to quickly fill the upper cylinder 4 for a water pressure test, the upper valve 603 and the lower valve 604 can be opened to inject water and gradually increase the water pressure in the upper cylinder 4 and the lower cylinder 5. During the spray test, only the upper valve 603 is opened to control the water flow into the spray assembly for the spray test.

[0050] As a preferred structure in this embodiment, such as Figure 4 As shown, clamping assemblies are symmetrically arranged on both sides of the inner hole 201 on the top surface of the workbench 1. The clamping assemblies include an L-shaped mounting bracket 8 fixedly connected to the top surface of the workbench 1, and multiple telescopic columns 801 slidably arranged on the mounting bracket 8. Springs 802 are fitted on the telescopic columns 801. One end of the spring 802 is fixedly connected to the mounting bracket 8, and the other end is fixedly connected to the bottom of the telescopic column 801.

[0051] In practice, the operator holds the telescopic column 801 with the inner hole 201 and pulls it upward, compressing the spring 802. The telescopic column 801 is then moved to a suitable position so that its bottom presses against the edge of the waterproof fabric. It is then slowly released, and relying on the elastic restoring force of the spring 802, the telescopic column 801 automatically moves downward, fixing the fabric to the top plate 2.

[0052] To better observe the water seepage of the fabric, such as Figure 1 As shown, a camera 7 is fixedly installed inside the workbench 1, with the camera 7 facing the inner hole 201. The camera 7, facing the inner hole 201 of the workbench 1, can clearly and comprehensively record the state changes of the waterproof fabric throughout the entire testing process.

[0053] Based on the above configuration, a fixing plate 203 is fixedly installed on the bottom surface of the top plate 2 on one side of the inner hole 201. A water-absorbing paper 204 is fixedly installed on the fixing plate 203, extending into the inner hole 201. By positioning the water-absorbing paper 204 on one side of the inner hole 201 via the fixing plate 203 and extending it into the inner hole 201, it can contact the fabric. Once water seeps out, the water-absorbing paper 204 can quickly absorb it. By observing the wetness of the water-absorbing paper 204, waterproofing issues at the fabric edges can be detected promptly, providing crucial data for evaluating the fabric's waterproofness.

[0054] In addition, such as Figure 1 As shown, the bottom of the workbench 1 is fixed with multiple support legs 101 for support.

[0055] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
