[0026] 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.

[0027] like Figures 1-6 As shown, this utility model provides a technical solution: a non-woven fabric experimental rain tester, including a frame 1, a funnel assembly 2 and a sample fixing platform 3. The lower end of the frame 1 is fixedly installed on the sample fixing platform 3. The funnel assembly 2 is detachably installed on the frame 1. The funnel outlet end of the funnel assembly 2 is connected to a nozzle 4 that communicates with the funnel. The nozzle 4 is located above the platform surface of the sample fixing platform 3. A water receiving trough 5 is spliced ​​at the bottom of the sample fixing platform 3. The water receiving trough 5 surrounds the bottom of the sample fixing platform 3 and fits perfectly. The water receiving trough 5 is U-shaped. The trough body of the water receiving trough 5 is distributed in front of and on both sides of the sample fixing platform 3. The water receiving trough 5 and the sample fixing platform 3 are two independent and separate parts, which are easy to clean separately and are also convenient to install. During the water receiving process, the water flows into the water receiving trough 5 for collection, so that the bottom of the sample fixing platform 3 is not easy to get wet.

[0028] The sample fixing platform 3 includes a placement platform 31 with a sloping top surface and a fabric pressing frame 32;

[0029] The placement platform 31 is made of a single piece of folded stainless steel plate, and the tail of the top surface of the placement platform 31 extends obliquely forward. The placement platform 31 is simple to form and has high production efficiency.

[0030] The pressing frame 32 has a hinged end at one end and a free end at the other end. The pressing frame 32 is placed on the top surface of the placement table 31 and is in contact with the top surface. The hinged end of the pressing frame 32 is hinged at the top position of the top surface of the placement table 31.

[0031] A buckle 6 is provided at the tail end of the top surface of the placement table 31 corresponding to the free end of the fabric pressing frame 32, and the placement table 31 can lock the fabric pressing frame 32 through the buckle 6.

[0032] The fabric pressing frame 32 is U-shaped. The hinge end of the fabric pressing frame 32 is bent into a C-shaped groove and a rotating shaft 321 is inserted. The hinge end of the fabric pressing frame 32 is hinged to the top of the top surface of the placement platform 31 through the rotating shaft 321. The fabric pressing frame 32 is used to press on the cut non-woven fabric sample to be tested. The shape of the fabric pressing frame 32 is conducive to pressing on the corners of the non-woven fabric sample to ensure flatness. In addition, the shape of the fabric pressing frame 32 does not trap water, so it does not affect the rain test and is not easy to splash water. After clamping the non-woven fabric, the fabric pressing frame 32 is fixed and pressed by the buckle 6, which makes the fixing of the non-woven fabric simple and convenient.

[0033] The buckle 6 includes a locking pin 61 and a nut 62. The locking pin 61 is limited and rotatably connected to the top surface of the placement platform 31 by the nut 62. The free end of the fabric pressing frame 32 is provided with a slot 322 that interlocks with the locking pin 61 at the position corresponding to the locking pin 61. The locking pin 61 can be rotated to a position perpendicular to the slot 322 to interlock, and the locking pin 61 can be rotated to a position parallel to the slot 322 to unlock. The fabric pressing frame 32 can rotate. The buckle 6 has a simple structure and the operation of fixing the free end of the fabric pressing frame 32 is simple, which improves the convenience of the experiment.

[0034] A water baffle assembly 7 can also be detachably installed on the stand 1, and the water baffle assembly 7 is located below the funnel assembly 2. The water baffle assembly 7 is used to catch the water droplets that leak from the nozzle 4 after the rain test. During the rain test, the water baffle assembly 7 can be turned to one side without affecting the rain test. The mounting brackets of the funnel assembly 2 and the water baffle assembly 7 are both detachable and can be locked by locking bolts 8.
