Furthermore, the outer ring 430 is provided with multiple outer ring screw holes 4301 corresponding to the first screw holes 420 on the tray 42. Bolts (not shown) engage with the corresponding first screw holes 420 on the tray 42 through the outer ring screw holes 4301 to fix the tray 42 and the outer ring 430 of the bearing 43. The inner ring 431 is provided with multiple inner ring screw holes 4302 corresponding to the second screw holes 440 on the connector 44. Bolts (not shown) engage with the corresponding second screw holes 440 on the connector 44 through the inner ring screw holes 4302 to fix the inner ring 431 of the bearing 43 and the connector 44. The outer ring 430 is also connected to a driving component (not shown), which can drive the outer ring 430 to rotate, thereby driving the tray 42 to rotate at a uniform speed of 1 r / min to meet the rotation test requirements in the IPX1 waterproof test. The top of the angle adjuster 45 is fixed to the bottom of the connector 44 and is mounted on the base 40. The angle adjuster 45 has an adjustment range of ±25° in the horizontal direction, which allows the tray 42 to tilt within a range of ±25° in the horizontal direction to meet the test requirements for the tilt angle of the test product in the IPX2 waterproof test. Optionally, the surface of the tray 42 is made of a special material and / or texture to prevent the test product from slipping off the surface of the tray 42 when it is tilted.

The outside of the water storage tank 5 is also provided with a drain outlet (not shown). When it is necessary to replace the test water, the operator can directly open the drain outlet (not shown) on the water storage tank 5 to drain the water. After the drainage is completed, the drain outlet (not shown) can be closed and new test water can be added to the water supply tank 101.

[0031] In other alternative embodiments, the top plate 10 may also be equipped with a water pump (not shown) and a water pumping pipe (not shown) and a water supply pipe (not shown) connected to the water pump (not shown). The water pumping pipe (not shown) extends into the interior of the water storage tank 5, and the water supply pipe (not shown) is connected to the water supply tank 101. By driving the water pump (not shown) to draw water from the water storage tank 5 through the water pumping pipe (not shown) and re-enter the water supply tank 101 through the water supply pipe (not shown), the test water can be reused, reducing the steps of draining and replacing the test water. When it is necessary to replace the test water, the operator only needs to open the drain port (not shown) on the water storage tank 5 to drain the water. After the drainage is completed, the drain port (not shown) is closed and new test water is added to the water supply tank 101.
