Furthermore, most devices lack an effective fixed support mechanism, requiring manual hand-holding for stability during testing. This is not only cumbersome to operate but also susceptible to shaking or displacement due to human factors, thus affecting the reliability of the test data. These structural defects limit testing efficiency and increase the difficulty of implementing water quality monitoring. Therefore, those skilled in the art have provided a portable rapid drinking water testing device to solve the problems mentioned in the background art. Utility Model Content

Figure 1 , Figure 2 , Figure 3 The device includes a housing 1, a display screen 2 on the front of the housing 1, a control panel 3 below the display screen 2, a water quality detection unit inside the housing 1, and an elastic clip 4 installed on the rear of the housing 1, allowing the housing 1 to be clipped to clothing or a belt for easy carrying. A drain pipe 5 is connected to the lower end of the housing 1, and a water inlet pipe 6 is connected to the upper end of the housing 1. A rubber sleeve 7 is installed inside the water inlet pipe 6, and the internal through-hole of the rubber sleeve 7 is inverted conical. This inverted conical design of the rubber sleeve 7 enables… To ensure a suitable and sealed connection for drinking water outlet pipes of different diameters, a first clamping plate 8 is provided at the upper end of the inlet pipe 6, a second clamping plate 9 is provided on one side of the first clamping plate 8, a limiting sleeve 801 is installed on the outer side of the first clamping plate 8, a U-shaped rod 10 is provided inside the limiting sleeve 801, a rotating sleeve 11 is provided between the two ends of the U-shaped rod 10, a bolt 12 is provided in the middle of the rotating sleeve 11, a limiting groove 901 is opened on the outer side of the second clamping plate 9, and a limiting block 13 is rotatably engaged in the limiting groove 901.

[0020] Please see Figure 1 , Figure 2 , Figure 3 A connector 601 is installed at the upper end of the water inlet pipe 6. The first clamping plate 8 and the second clamping plate 9 are rotatably connected to the water inlet pipe 6 through the corresponding connectors 601. The U-shaped rod 10 is rotatably sleeved with the rotating limiting sleeve 801. The rotating sleeve 11 is rotatably sleeved with the two ends of the U-shaped rod 10. The bolt 12 is threadedly sleeved with the middle of the rotating sleeve 11. The end of the bolt 12 is rotatably snapped with the limiting block 13. In the above structure, the second clamping plate is driven to retract inward by the threaded connection between the bolt and the rotating sleeve, and the first clamping plate is driven to move synchronously by the U-shaped rod, thereby realizing the clamping and fixing of the drinking water outlet pipe. Rubber pads 14 are installed on the inner walls of the first clamping plate 8 and the second clamping plate 9 to increase the friction during clamping.

[0021] In this utility model, a display screen 2 is provided on the front side of the outer casing, and a control panel 3 is provided below the display screen 2. A water quality detection unit is provided inside the outer casing. A drain pipe 5 is connected to the lower end of the outer casing, and a water inlet pipe 6 is installed at the upper end of the outer casing. A rubber sleeve 7 is provided inside the water inlet pipe 6. The inside of the rubber strip is inverted conical. Two connectors 601 are provided on the water inlet pipe 6. A first clamping plate 8 is rotatably connected to one connector 601, and a second clamping plate 9 is rotatably connected to the other connector 601. A limit sleeve 801 is installed on the outside of the first clamping plate 8. A U-shaped rod 10 is connected to the rotating sleeve 11 inside the limit sleeve 801. A limit groove 901 is opened on the outside of the second clamping plate 9. A limit block 13 is rotatably engaged in the limit groove 901. A bolt 12 is rotatably engaged on the outside of the limit block 13. A rotating sleeve 11 is connected between the two ends of the U-shaped rod 10. The bolt 12 is threadedly engaged with the rotating sleeve 11.

[0022] When connecting the inlet pipe 6 on the housing 1 to the drinking water outlet pipe, the end of the drinking water outlet pipe is pressed against the rubber sleeve 7 inside the inlet pipe 6. Since the inner wall of the rubber sleeve 7 is inverted conical, it can be used to seal the drinking water outlet pipes of different diameters. When the inlet pipe 6 is sleeved with the drinking water outlet pipe, the first clamping plate 8 and the second clamping plate 9 are on both sides of the drinking water outlet pipe. Then, the bolt 12 is rotated. Since the end of the bolt 12 is rotated and engaged with the rotating block, and the middle is threadedly sleeved with the rotating sleeve 11, the distance between the rotating sleeve 11 and the rotating block increases after the bolt 12 is rotated, thereby causing the second clamping plate 9 to contract inward. This causes the first clamping plate 8 to contract relatively through the U-shaped rod 10, thereby completing the relative clamping of the first clamping plate 8 and the second clamping plate 9, and fixing the inlet pipe 6 and the drinking water outlet pipe. A rubber pad 14 is provided on the inner side of the first clamping plate 8 and the second clamping plate 9 to increase the friction during clamping. This structure can position the housing 1 and avoid the problem of having to hold the testing equipment for a long time when conducting water quality testing.

[0023] Furthermore, an elastic clamp 4 is provided on the rear side of the housing 1, which allows the device to be clamped to clothing or belts for easy carrying.
