[0051] When the turntable 21 rotates, the turntable 21 drives the multiple bases 210 thereon to make circular motions, thereby driving the multiple fabrics to make circular motions synchronously, and at the same time, the turntable 21 drives the gear 24 to move along the inner ring of the inner gear ring 23, at this time, the inner gear ring 23 meshes and drives the gear 24 to rotate, and the gear 24 meshes and drives the outer gear ring 25 to rotate, so that the outer gear ring 25 drives the guide cylinder 26 to rotate, so that the guide inclined groove 27 and the guide rod 28 on the side wall of the guide cylinder 26 rotate and move relative to each other, wherein the guide inclined groove 27 is composed of two symmetrically arranged arc inclined grooves, and the two guide rods 28 are respectively movably engaged in the two arc inclined grooves, when the guide inclined groove 27 and the guide rod 28 rotate and move relative to each other, the two guide rods 28 move back and forth up and down along the two arc inclined grooves, thereby driving the support seat 212 and the support shaft 29 to swing back and forth left and right, and then the support shaft 29 drives the base plate 31 and the fabric to swing back and forth, so as to perform a dynamic waterproof test on the fabric;

[0052] When it is necessary to perform a static waterproof test on the fabric, the turntable 21 remains stationary, and the base plate 31 is manually rotated, so that the base plate 31 rotates through the support shaft 29 and the support seat 212, so that the support seat 212 drives the guide rod 28 to rotate and move in the guide inclined groove 27, so that the inclination angle of the base plate 31 can be adjusted through the cooperation of the guide inclined groove 27 and the guide rod 28, so that the fabric can be statically waterproof tested at different angles on the base plate 31.

[0054] Embodiment 4

[0055] See also Figure 1-Figure 4 As shown, the difference between this embodiment and the above embodiment is that a water blocking mechanism 4 capable of shielding the sprinkler head 5 is further installed on the test machine body 1, and the water blocking mechanism 4 includes a funnel 41 and a guide pipe 42, and the guide pipe 42 is rotatably installed on the inner wall of the test machine body 1, and the top of the guide pipe 42 is provided with an inclined pipe capable of extending to the bottom of the sprinkler head 5, and the top of the guide pipe 42 is connected with the funnel 41, and the bottom end of the guide pipe 42 extends into the water collection tank 11;

[0056] Among them, when conducting a waterproof test on the fabric, the water pressure fluctuates greatly when the sprinkler head 5 is opened and closed, thereby causing a large fluctuation in the amount of spray water, which is easy to affect the test accuracy. By providing the funnel 41 and the guide tube 42, the funnel 41 can be rotated and moved to the bottom of the sprinkler head 5 before the sprinkler head 5 is opened, so as to block and receive the water sprayed from the sprinkler head 5 to prevent the spray water from directly spraying onto the fabric. At the same time, the guide tube 42 guides the water to the sump 11, and the funnel 41 is rotated and moved away after the water flow in the sprinkler head 5 is stabilized; accordingly, before the spraying is finished, the funnel 41 is first rotated and moved to the bottom of the sprinkler head 5 to block and receive the water sprayed from the sprinkler head 5, and then the sprinkler head 5 is closed; through the cooperation of the funnel 41 and the guide tube 42, the spray water flow is more stable when the fabric is subjected to a waterproof test, which is beneficial to improving the test accuracy.

[0058] Among them, the pin shaft 47 is upwardly inserted into the pin hole 46 on the fixing plate 43 under the elastic force of the spring 49, so that the positioning plate 44 and the fixing plate 43 are pinned and fixed by the pin shaft 47 and the pin hole 46, thereby limiting and locking the guide tube 42 to improve the installation stability of the guide tube 42 and the funnel 41, and ensure that the funnel 41 is exactly located below the sprinkler head 5. When the funnel 41 needs to be rotated away, the pin shaft 47 is first pulled downward by the pull handle 48 to pull the top end of the pin shaft 47 out of the pin hole 46 on the fixing plate 43 to release the lock between the positioning plate 44 and the fixing plate 43, and then the guide tube 42 can be rotated to rotate the funnel 41 away.

[0063] After the water spray test is completed, turn off the sprinkler head 5 and the motor, remove the fabric and the absorbent cotton 32, and measure the weight of the absorbent cotton 32 again using a weighing instrument.
