When the water level inside the box body 2 reaches the drain pipe 10, it will flow to the designated position through the drain pipe 10 for recycling.

[0025] Two mounting plates are fixedly connected to both sides of the terminal water testing pipe 1, and each mounting plate is provided with a through hole. By setting the mounting plates, the box body 2 can be installed at a designated position using expansion screws.

[0026] A fixing assembly 7 is arranged above the box body 2, and the fixing assembly 7 includes a first ring 701 fixedly connected to the outer surface of the connecting pipe 3, and the first ring 701 contacts the upper surface of the box body 2, and a cylinder 703 is fixedly connected to the side of the first ring 701 away from the box body 2, and a round rod 704 is slidably connected to the inside of the cylinder 703, and a pressure plate 706 is rotatably installed at one end of the round rod 704 located outside the cylinder 703, and the number of cylinders 703 is four, and the four cylinders 703 are distributed in a circular array on the upper surface of the first ring 701.

[0027] A second circular ring 702 is fixedly connected to the outer surface of the terminal water testing pipe 1, and a through groove matched with the pressure plate 706 is opened inside the second circular ring 702. The pressure plate 706 passes through the through groove and is pressed against the upper surface of the second circular ring 702; when the pressure plate 706 is rotated to be parallel to the through groove, the pressure plate 706 can be moved through the through groove to the top of the second circular ring 702, and then the pressure plate 706 above the second circular ring 702 is rotated to be perpendicular to the through groove, and then the pressure plate 706 can be pressed against the upper surface of the second circular ring 702.

[0028] One end of the round rod 704 located inside the cylinder 703 is fixedly connected to the first spring 705, and the end of the first spring 705 away from the round rod 704 is fixedly connected to the inner bottom wall of the cylinder 703. After the connection between the terminal water test pipe 1 and the connecting pipe 3 is completed, the first spring 705 is in an elongated state.

[0029] A buffer assembly 8 is arranged between the filter screen 9 and the connecting pipe 3, and the buffer assembly 8 includes a support plate 801 fixedly connected to the inside of the box body 2, and a second spring 803 is fixedly connected to the upper surface of the support plate 801, and an end of the second spring 803 away from the support plate 801 is fixedly connected to a buffer plate 802, and the buffer plate 802 is located directly below the connecting pipe 3; there are four second springs 803, and the four second springs 803 are respectively located at the four corners of the buffer plate 802, and the top of the buffer plate 802 is provided with a slope facing outward, so that the water on the buffer plate 802 can flow down more smoothly.

After the water flow falls on the buffer plate 802, it will drive the buffer plate 802 to move downward. The downward movement of the buffer plate 802 will drive the second spring 803 and the hydraulic damper 804 to deform, thereby buffering the impact force of the water flow. The buffered water flow will fall onto the filter screen 9 for filtration, and the filtered water flow will continue to fall to the bottom of the box 2.

[0031] When conducting the test, first, insert one end of the terminal water test pipe 1 into the interior of the connecting pipe 3 and press against the sealing ring 5 inside the connecting pipe 3, then rotate the pressure plate 706 to be parallel to the through groove and pull it to the top of the second ring 702, then rotate the pressure plate 706 to be perpendicular to the through groove and release the pressure plate 706. At this time, under the action of the first spring 705, the pressure plate 706 can be pressed against the upper surface of the second ring 702, thereby achieving a tight connection between the terminal water test pipe 1 and the connecting pipe 3. Thereafter, the water sprayed out through the terminal water test pipe 1 will flow through the connecting pipe 3 to the interior of the box body 2, and then the buffer assembly 8 inside the box body 2 will buffer the water flow, and the filter screen 9 will filter the buffered water flow, and the filtered water will be discharged to the designated location through the drain pipe 10 for use.
