[0002] With the development of science and technology, people's demand for outdoor sports and adventure activities is increasing. In these activities, windproof and waterproof clothing has become a must-have equipment. However, traditional windproof and waterproof fabrics have some problems, such as being airtight, easily damaged, and susceptible to moisture. In order to solve these problems, some new volcanic rock fabrics are gradually being used in the field of outdoor clothing.

[0003] Volcanic rock fabrics have many excellent properties, such as light weight, warmth retention, breathability, moisture absorption and perspiration wicking, etc. These properties make volcanic rock fabrics have broad application prospects in the field of outdoor clothing. However, there is a lack of windproof and waterproof performance testing equipment for volcanic rock fabrics on the market. Commonly used windproof and waterproof performance testing equipment is a static test of fabrics. As outdoor fabrics, volcanic rock fabrics are used in a dynamic environment. The test principle and equipment structure of existing windproof and waterproof testing equipment are not suitable for volcanic rock fabrics.

[0004] Therefore, we need to develop a new windproof and waterproof testing equipment based on the characteristics of volcanic rock fabrics to meet market demand. Summary of the invention

[0024] The present application is described in further detail below. It is necessary to point out that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technicians in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0025] Example 1

[0026] like Figure 1-4 As shown, a windproof and waterproof testing device for volcanic rock fabrics includes a testing box 1 with an upper opening, a plurality of plug holes are provided at the top of the testing box 1, and plug rods 19 are movably installed in the plug holes. A downward pressing frame 2 for clamping the volcanic rock fabric a at the upper opening is fixed to the top of the plurality of plug rods 19. The downward pressing frame 2 has the same shape as the testing box 1, and can make good contact with the top of the testing box 1 when in contact with the testing box 1.

[0027] A telescopic member 3 is fixedly provided on the pressing frame 2 , a plurality of connecting blocks 12 are fixedly provided at the telescopic end of the telescopic member 3 , and a circular ring 13 is fixed at the bottom end of the connecting block 12 .

[0028] An air storage component is fixedly provided at the inner bottom of the detection box 1, and a nozzle 4 communicating with the inner cavity of the air storage component is fixedly provided on the air storage component.

[0029] It should be noted that the test water is first poured into the test box 1, and then the volcanic rock fabric a to be tested is cut into an appropriate size (the size of the fabric a needs to reserve redundant length on both sides of the pressing frame 2), and then laid on the upper opening of the test box 1, and the pressing frame 2 is moved downward to press the volcanic rock fabric a tightly against the test box 1. The telescopic member 3 is extended so that the telescopic end of the telescopic member 3 drives the ring 13 to contact the top center of the volcanic rock fabric a. When the telescopic member 3 continues to extend, it can drive the middle part of the volcanic rock fabric a to move downward until it enters the water. Because the edge of the volcanic rock fabric a is clamped by the test box 1 and the pressing frame 2, the tightness of the volcanic rock fabric a changes during the downward movement of the middle part of the volcanic rock fabric a. The tightness of the volcanic rock fabric a can be indirectly adjusted by adjusting the telescopic amount of the telescopic member 3 to simulate different tightness during use.

[0030] The telescopic member 3 may be an electric push rod, which can reciprocate and extend, and can also maintain the telescopic length.

[0031] At the same time, because the nozzle 4 is located directly below the ring 13, the nozzle 4 makes the contact portion of the volcanic rock fabric a and the ring 13 concave upward after passing through the ring 13. The gas storage member sprays air through the nozzle 4, and the gas sprayed by the nozzle 4 forms a water removal area at the concave portion, and the water in the water removal area is discharged. At this time, the gas sprayed by the nozzle 4 can directly act on the volcanic rock fabric a, eliminating the influence of water on the movement of the gas.

[0032] The volcanic rock fabric a can be observed by sensory judgment, that is, visually inspect whether there is water seepage on the upper surface of the volcanic rock fabric a, and manually inspect whether there is airflow on the upper surface of the volcanic rock fabric a. If there is water seepage, it means that the waterproof effect is not good, and if there is obvious airflow, it means that the windproof effect is not good.

[0033] Furthermore, a humidity sensor and an anemometer may be fixedly provided on the ring 13, and the detection result may be quantitatively detected by the humidity sensor and the anemometer. For example, the larger the wind speed value measured by the anemometer, the worse the windproof effect of the fabric a is.

[0034] In order to improve the clamping effect on fabric a, a plurality of limit rods 16 are fixedly provided on the outer wall of the detection box 1, and a plurality of elastic bands 17 corresponding to the limit rods 16 are fixedly provided on the pressing frame 2. When clamping fabric a, the elastic bands 17 are tied to the limit rods 16, so that the pressing frame 2 can form sufficient clamping force on fabric a to prevent the edge of fabric a from detaching from the pressing frame 2 due to the fabric a being tightened.

[0035] In the above embodiment, the gas storage member includes a cylinder sleeve 5 fixedly mounted on the detection box 1, the bottom of the cylinder sleeve 5 is a closed structure, and has a central hole 18. A movable sleeve is provided with a moving rod 6 in the cylinder sleeve 5, and a through hole 7 is provided on the moving rod 6 to connect the nozzle 4 and the inner cavity of the cylinder sleeve 5, and a No. 1 one-way valve 8 for controlling the gas to move from the cylinder sleeve 5 to the nozzle 4 is fixedly installed in the through hole 7.

[0036] A spring 9 is arranged in the cylinder sleeve 5. When the telescopic member 3 does not squeeze the spray head 4, the spring 9 drives the moving rod 6 to move upward.

[0037] An air inlet 10 is provided at the bottom of the test box 1 corresponding to the position of the cylinder sleeve 5, and the air inlet 10 is connected to the central hole 18. A second one-way valve 11 for controlling the gas from the outside to enter the cylinder sleeve 5 is fixedly installed at the air inlet 10.

[0038] The working principle of the gas storage part is as follows: when the connecting block 12 moves downward and contacts the nozzle 4, the nozzle 4 is driven to move downward together, so that the moving rod 6 is compressed and enters the cylinder sleeve 5, so that the gas in the cylinder sleeve 5 is compressed. The compressed gas reaches the nozzle 4 through the through hole 7 on the moving rod 6 and is ejected from the nozzle 4. At this time, the No. 1 check valve 8 is opened and the No. 2 check valve 11 is closed.

[0039] When the connecting block 12 moves upward, the spring 9 drives the moving rod 6 to move upward, so that the air pressure in the cylinder sleeve 5 is reduced, the No. 2 one-way valve 11 is opened and the No. 1 one-way valve 8 is closed, and the gas enters the cylinder sleeve 5 from the outside through the air inlet 10.

[0040] Example 2

[0041] On the basis of Example 1, further, a rotating member 14 is fixedly provided at one end of the moving rod 6 located inside the cylinder sleeve 5. The rotating member 14 has an external thread and is annular, which will not affect the movement of the gas in the cylinder sleeve 5. The inner wall of the cylinder sleeve 5 has an internal thread, and the rotating member 14 is threadedly connected to the cylinder sleeve 5. The rotating member 14 rotates while moving relative to the cylinder sleeve 5, driving the moving rod 6 to rotate, so that the nozzle 4 also rotates synchronously, and a plurality of friction protrusions 15 are provided on the nozzle 4. When the nozzle 4 contacts the fabric a, it rotates, and the friction protrusions 15 can form continuous and strong friction on the surface of the fabric a, which can accelerate the wear of the fabric a, so as to simulate the use scenario of the fabric a being worn when used outdoors.

[0042] The rotating member 14 is detachable, and the spray head 4 does not rotate any more after the rotating member 14 is detached.

[0043] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
