[0025] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention. On the contrary, the embodiments of the present invention include all changes, modifications, and equivalents that fall within the spirit and connotation of the appended claims.

[0026] The following describes a testing device for waterproof paper material according to an embodiment of the present utility model in conjunction with the accompanying drawings.

[0027] like Figure 1 As shown, the testing device for waterproof paper material of the embodiment of the utility model may include an installation box 1, a clamping mechanism 2, a circulation mechanism 3, a spraying mechanism 4, a testing mechanism 5 and a support rod 6.

[0028] The installation box 1 is concave in shape, and a plurality of water seepage holes 11 are provided on both sides of the installation box 1 .

[0029] It should be noted that, in this embodiment, the water seepage holes 11 on the installation box 1 can collect water overflowing from the annular block 21 .

[0030] As a possible situation, the side wall of the installation box 1 is in contact with the guide block 23, so that the overflowed water can directly flow into the interior of the installation box 1, thereby accelerating the water circulation.

[0031] The test box 51 is provided with two slots 511 , and the positions of the slots 511 and the positions of the inclined blocks 25 correspond to each other.

[0032] It should be noted that the provided groove 511 is used to install the waterproof paper material on the top of the test box 51 .

[0033] The test mechanism 5 is installed on the top of the installation box 1 , and the clamping mechanism 2 is installed on the top of the test mechanism 5 . The clamping mechanism 2 may include an annular block 21 , a seepage plate 22 , a plurality of guide blocks 23 , a water permeable hole 24 , an inclined block 25 and a sealing strip 26 .

[0034] Among them, multiple guide blocks 23 are installed on the side of the annular block 21, multiple seepage holes 11 are opened at the bottom of the guide block 23, multiple seepage plates 22 are installed on the annular block 21, two inclined blocks 25 are relatively installed at the bottom of the seepage plate 22, and two pressure sealing strips 26 are relatively installed at the bottom of the seepage plate 22.

[0035] It is understandable that when the material is subjected to a waterproof test, water will flow out from under the inner wall of the annular block 21 and the guide block 23 .

[0036] It should be noted that, in the present embodiment, the water permeable hole 24 at the bottom of the guide block 23 and the seepage plate 22 are connected to each other, and through holes corresponding to the water permeable hole 24 are provided on the installation box 1 .

[0037] The circulation mechanism 3 is installed on one side of the installation box 1 , and the circulation mechanism 3 may include a water tank 31 , a water pump 32 and a connecting pipe 33 .

[0038] The water tank 31 is installed on one side of the installation box 1 , the water pump 32 is installed inside the water tank 31 , the connecting pipe 33 is connected to the spraying mechanism 4 , and a water inlet pipe 8 is provided at the connection between the installation box 1 and the water tank 31 .

[0039] It can be understood that the water flowing in from the water inlet pipe 8 can be transferred to the nozzle 42 by the water pump 32 and the connecting pipe 33 through the provided circulation mechanism 3, so as to perform secondary water circulation.

[0040] The support rod 6 is installed on the circulation mechanism 3 , and the spraying mechanism 4 is installed on the support rod 6 . The spraying mechanism 4 may include a top plate 41 and a spray head 42 .

[0041] A plurality of nozzles 42 are installed on the top plate 41 , and the nozzles 42 are connected to the connecting pipe 33 .

[0042] It should be noted that a push rod motor capable of adjusting the height longitudinally and a rotation mechanism capable of adjusting the angle transversely are provided inside the support rod 6 to control the distance between the nozzle 42 and the waterproof paper material.

[0043] Specifically, when the waterproof paper material needs to be tested, the waterproof paper material is first cut to a suitable size (larger than the length of the test box 51), and then both ends are inserted into the strip groove 511. After that, the clamping mechanism 2 is placed on the test box 51, and the positions of the inclined block 25 and the strip groove 511 correspond to each other, which are used to clamp the waterproof paper material. At the same time, the sealing strips 26 on both sides press the other two sides of the waterproof test paper 54.

[0044] Turn on the water pump 32, and the water pump 32 will draw water from the water tank 31 to spray the waterproof paper material. When the performance of the waterproof paper material is good (impermeable), the water will flow from the seepage plate 22 to the water permeable hole 24 and gather into the installation box 1. When the water volume is large, the water can also flow from the side of the installation box 1 into the installation box 1, and enter the water tank 31 again through the connecting pipe 7 and the water inlet pipe 8 to realize water circulation and save water resources.

[0045] When the performance of the waterproof paper material does not meet the standard (not waterproof), when water rushes onto the waterproof paper, the water will penetrate from the waterproof paper material into the test paper 54, and the test paper 54 will change color when it encounters water. Therefore, it can be known that the waterproof paper material is unqualified.

[0046] It should be noted that, in this embodiment, a transparent window may be provided on the surface of the test box 51 for observing changes in the test paper 54 .

[0047] The test paper 54 contains special chemical indicators (such as acid-base indicators) when it comes into contact with water. These indicators will react with acid and base when they come into contact with water, resulting in a color change. At the same time, the test paper 54 is bonded to the inclined plate 53. After the color is developed, in order not to affect the effect of the subsequent test paper 54, the test paper 54 can be replaced, which is more practical.

[0048] It should be noted that a connecting pipe 7 is provided at the bottom of the installation box 1, and a solenoid valve is provided at the connection between the connecting pipe 7 and the test box 51. When performing a waterproof test, if the test paper 54 changes color, the water in the installation box 1 needs to flow into the water tank 31, and then the solenoid valve is opened to drain the inside of the test box 51.

[0049] In one embodiment of the present invention, Figure 1 As shown, the testing mechanism 5 may include a testing box 51 , a connecting rod 52 , an inclined plate 53 , a testing paper 54 and a water seepage port 55 .

[0050] The test box 51 is installed on the installation box 1 , two connecting rods 52 are installed on the inner wall of the test box 51 , the inclined plate 53 is connected to the water seepage port 55 , the test paper 54 is arranged on the inclined plate 53 , and the water seepage port 55 is installed between the bottoms of the two inclined plates 53 .

[0051] It can be understood that the water inside the test box 51 can be discharged through the provided water seepage port 55 .

[0052] In summary, the test device for waterproof paper material of the embodiment of the utility model can significantly reduce the water resource consumption during the test process by improving the design of the test device. At the same time, it can ensure that the water droplets can more accurately simulate the contact situation in the actual environment, and avoid splashing onto auxiliary detection tools such as water-sensitive color developing paper, thereby ensuring the accuracy of the test results.
