[0028] Beneficial effects of the present invention:

[0029] The present invention provides a tent moisture permeability testing device and a testing method. Before a fabric body is subjected to a water spray moisture permeability test, the fabric body can be compressed and fixed, so as to avoid water splashing into the back side of the fabric body during the test and affecting the accuracy of subsequent test results. Specifically, a compression component is provided. When a staff member needs to conduct a moisture permeability test on the fabric body, the fabric can be first placed on the top of a compression platform, and then a clamp plate is sleeved on the outer wall of the fabric body. During the sleeve of the clamp plate, the compression and fixation of the fabric body can be achieved by clamping the compression block in the sealing hole. At the same time, a positioning ring plate provided below the sealing hole will be clamped in the annular groove, so that the fabric body can be tightly fitted on the top of the compression platform, so as to avoid a gap between the fabric body and the compression platform, resulting in water vapor penetrating from the gap to the back side of the fabric body during subsequent tests, causing inaccurate test results.

[0030] A tent moisture permeability testing device and testing method provided by the present invention can avoid splashing of water generated during the detection process, thereby improving the accuracy of the detection result. Specifically, a water retaining cover, a circular ring plate and a positioning component are provided. The water retaining cover can be installed after the staff has completed the compression and fixing of the fabric body. The water retaining cover can block and collect the water generated during the detection process, thereby facilitating the subsequent circulation component to recycle the water. During the installation of the water retaining cover, the clamping column is inserted into the positioning groove at the top of the fixing seat. During the process of inserting the clamping column into the positioning groove, the fixing table located in the fixing groove will first contact with the two groups of clamping blocks. Since the cross-section of the fixing table is an isosceles trapezoid, the clamping blocks can be squeezed to both sides by the fixing table during the gradual insertion of the clamping column. At this time, the spring sleeved on the outer wall of the cross column is in a compressed state. When the clamping block moves to the lower end of the fixing table, the spring in the compressed state will immediately contact with the two groups of clamping blocks. When the water retaining cover is removed, the staff can continue to press down the clamping column, and the clamping block will move with the downward movement of the clamping column, and continue to press down when the clamping block moves the two sides of the slide. At this time, the slide can squeeze the clamping block open again. When the clamping block is pressed down to the point where it cannot be pressed, the clamping block will be clamped on the outer wall of the slide by the action of the spring. At this time, when the staff lifts the water retaining cover upward, the clamping block will lift the clamped slide upward together with the clamping block until the slide contacts the fixed platform. At this time, the clamping block can be quickly separated from the slide, completing the rapid disassembly of the water retaining cover.

[0031] The present invention provides a tent moisture permeability testing device and testing method, which can realize the water spray moisture permeability detection of the fabric body in the inclined and vertical directions, thereby improving the accuracy of the detection result. Specifically, a water spraying component, an adjusting component and a lateral movement component are provided. After the staff completes the installation of the water retaining cover, the valve on the side of the water outlet pipe is opened. At this time, the water flow in the water tank will be discharged through the spray hole at the bottom of the spray head and directly fall on the surface of the fabric body, thereby realizing the moisture permeability detection of the fabric body. During the detection process, the rotating block can be rotated to drive the rotating column and the first threaded screw to rotate. During the rotation of the first threaded screw, the first threaded sleeve can be driven to rise. Through the rise of the first threaded sleeve, the support column can prop up the fixed seat, thereby realizing the fixed seat. The adjustment of the seat inclination simulates the water spraying state of the inclined surface and the top horizontal surface during the use of the tent, thereby improving the accuracy of the test results. At the same time, during the tilting process of the fixed seat, the first gear plate can be driven to rotate through the rotating column, and during the rotation of the first gear plate, the second gear plate can be driven to rotate together, and the second gear plate can be driven to rotate. During the rotation of the second threaded screw, the curved rod meshed on the outer wall thereof can be moved together, and at the same time, the curved rod is fixedly connected to the water conduit through a fixed ring sleeve. Therefore, during the horizontal movement of the curved rod, the sprinkler head can be driven to move horizontally together, so that when the fixed seat is rotated to the inclined angle, the sprinkler head is still directly above the fabric body, thereby ensuring the accuracy of the moisture permeability test results.

At this time, the slide 1207 can squeeze the clamping block 1211 open again. When the clamping block 1211 is pressed down to the point where it cannot be pressed, the clamping block 1211 will be clamped on the outer wall of the slide 1207 through the action of the spring. At this time, when the staff lifts up the water shield 7001, the clamping block 1211 will lift up the clamped slide 1207 together until the slide 1207 contacts the fixed platform 1205. At this time, the clamping block 1211 can be quickly separated from the slide 1207, completing the rapid disassembly of the water shield 7001.

[0055] Preferably, the bottom outer wall of the water shield 7001 is fixedly connected with a sealing plate 1214, the top of the fixing seat 14 is provided with a sealing groove 1213, the circumferential outer wall of the sealing plate 1214 is provided with an assembly groove, and a sealing ring 1215 is arranged inside the assembly groove, and the circumferential outer wall of the sealing ring 1215 is in contact with the circumferential inner wall of the sealing groove 1213. The sealing ring 1215 can prevent the back side of the fabric body 10 from being wetted by water vapor during the detection process.

[0056] A tent moisture permeability testing device and testing method, comprising the following steps:

[0057] Step 1. Place the fabric body 10 on the pressing table 7002 and fix it by the pressing assembly 7;

[0058] Step 2. Fix the water shield 7001 to the top of the fixing base 14 through the positioning assembly 12;

[0059] Step 3. Add the colored clean water into the water tank 3001 through the feed hopper 3002 and open the valve. Test water leaks out through the spray hole 3007 at the bottom of the spray head 3005 to spray the fabric body 10;

[0060] Step 4. After the fabric body 10 is horizontally sprayed with water, the fixing seat 14 is tilted by adjusting the component 8 and the lateral displacement component 11, and the water spraying process of the fabric body 10 is completed;

[0061] Step 5. After removing the water shield 7001, feed the white thin paper from the circular groove 13 until it is close to the back of the fabric body 10. After a period of time, take out the white thin paper and observe whether there is any wetness and color marks on the surface, thereby completing the moisture permeability detection of the fabric body 10.

[0062] In summary, with the help of the above technical solution of the present invention, when the staff needs to perform a moisture permeability test on the fabric body 10, the fabric can be first placed on the top of the pressing platform 7002, and then the clamp plate 7005 can be sleeved on the outer wall of the fabric body 10. During the sleeve of the clamp plate 7005, the pressing block 7006 can be clamped in the sealing hole 7003 to achieve the compression and fixation of the fabric body 10. At the same time, the positioning ring plate 7007 arranged below the sealing hole 7003 will be clamped in the annular groove 7004, so that the fabric body 10 can be closely fitted on the top of the pressing platform 7002, avoiding the generation of a gap between the fabric body 10 and the pressing platform 7002, resulting in water vapor penetrating from the gap into the fabric during subsequent testing. The back side of the fabric body 10 may cause inaccurate detection results. After the staff has completed the compression and fixation of the fabric body 10, the water shield 7001 can be installed. The water shield 7001 can block and collect the water flow generated during the detection process, which is convenient for the subsequent circulation component 5 to recycle the water flow. During the installation of the water shield 7001, the column 1201 is inserted into the positioning groove 1202 at the top of the fixed seat 14. During the insertion of the column 1201 into the positioning groove 1202, the fixed platform 1205 located in the fixed groove will first contact with the two groups of clamping blocks 1211. Since the cross-section of the fixed platform 1205 is an isosceles trapezoid, during the gradual insertion of the column 1201, the fixed platform 1205 will contact with the two groups of clamping blocks 1211. 1205 can squeeze the clamping block 1211 to both sides. At this time, the spring sleeved on the outer wall of the cross column 1212 is in a compressed state. When the clamping block 1211 moves to the lower end of the fixed platform 1205, the spring in the compressed state will immediately restore its deformation. At this time, the clamping block 1211 will quickly reset and move to the bottom of the fixed platform 1205. Through the limiting effect of the clamping block 1211, the clamping column 1201 cannot be detached from the inside of the positioning groove 1202, thereby realizing the rapid installation of the water retaining cover 7001 and ensuring the stability of the water retaining cover 7001 after installation, thereby avoiding the water retaining cover 7001 from falling off during the subsequent adjustment of the inclination angle of the fixing seat 14. At the same time, when people finish the inspection, they need to remove the water retaining cover 7001. When the clamping block 1211 is pressed down to the point where it cannot be pressed anymore, the clamping block 1211 is clamped on the outer wall of the slide 1207 by the action of the spring. At this time, when the staff lifts up the water retaining cover 7001, the clamping block 1211 lifts up the clamped slide 1207 together with the slide 1207 until the slide 1207 contacts the fixed platform 1205. At this time, the clamping block 1211 can be quickly separated from the slide 1207, completing the rapid disassembly of the water retaining cover 7001.After the staff has installed the water shield 7001, they open the valve on the side of the water outlet pipe 3006. At this time, the water flow inside the water tank 3001 will be discharged through the spray hole 3007 at the bottom of the spray head 3005 and directly fall on the surface of the fabric body 10, thereby realizing the moisture permeability detection of the fabric body 10. During the detection process, the rotating block 8001 can be rotated to drive the rotating column 8002 and the first threaded screw 8003 to rotate. During the rotation of the first threaded screw 8003, the first threaded sleeve 8006 can be driven to rise. Through the rise of the first threaded sleeve 8006, the support column 8009 can prop up the fixed seat 14, thereby realizing the adjustment of the inclination of the fixed seat 14, simulating the water spraying state of the inclined surface and the top horizontal surface during the use of the tent, and improving the accuracy of the detection result. At the same time, during the tilting process of the fixed seat 14, the first gear plate 1101 can be driven to rotate through the rotating column 8002, and during the rotation of the first gear plate 1101, the second gear plate 1114 can be driven to rotate together, and the second screw rod 1113 can be driven to rotate through the second gear plate 1114. During the rotation of the second screw rod 1113, the curved rod 1104 meshed on the outer wall thereof can be moved together. At the same time, the curved rod 1104 is fixedly connected to the water pipe 3004 through the fixing ring sleeve 1105. Therefore, during the horizontal movement of the curved rod 1104, the spray head 3005 can be driven to move horizontally together, so that when the fixed seat 14 rotates to the tilting angle, the spray head 3005 is still directly above the fabric body 10, ensuring the accuracy of the moisture permeability test results.

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
