[0024] This embodiment is a water quality testing and extraction device.
[0025] like Figure 1-4 As shown, the device includes a sampling cup 1, a telescopic rod 8 on one side of the sampling cup 1, a counterweight 2 fixedly installed on the lower outer surface of the sampling cup 1, lifting lugs 3 fixedly installed on the left and right sides of the upper outer surface of the sampling cup 1, a connecting rod 6 on the upper part of one side of the sampling cup 1, connecting arms 4 fixedly installed on the left and right ends of the outer surface of one side of the connecting rod 6, a connecting shaft 5 between the lifting lugs 3 and the connecting arms 4, and a fixing block 7 fixedly installed in the middle of the outer surface of one side of the connecting rod 6. A slot 12 is formed on the outer surface of one end of the fixing block 7. The upper outer surface of the fixing block 7 is provided with a snap-fit limiting hole 13. The lower end of the snap-fit limiting hole 13 is connected to the slot 12. A connecting block 9 is fixedly installed on the outer surface of one end of the telescopic rod 8. A limiting block 10 is fixedly installed on the outer surface of one end of the connecting block 9. A connecting component 11 is installed on one side of the outer surface of the limiting block 10. The connecting component 11 includes an insert 14, a mounting hole 15, a snap-fit pin 16, a guide hole 17, a guide rod 18, and a compression spring 19. The insert 14 is fixedly installed on one side of the outer surface of the limiting block 10.
[0026] The connecting shaft 5 is rotatably connected between the end of the connecting arm 4 away from the connecting rod 6 and the outer surface of the lifting lug 3; the mounting hole 15 is opened in the middle of the upper outer surface of the insert block 14, and the guide rod 18 and the compression spring 19 are both located in the mounting hole 15. The lower outer surface of the guide rod 18 is fixedly connected to the middle of the lower end of the mounting hole 15, and the compression spring 19 is movably sleeved on the outer wall of the guide rod 18; the guide hole 17 is opened in the middle of the lower outer surface of the locking pin 16, and the upper outer surface of the compression spring 19 is connected to the locking pin 16. The lower outer surface of the pin 16 is fixedly connected, and the lower outer surface of the compression spring 19 is fixedly connected to the bottom of the mounting hole 15; the snap-fit pin 16 is slidably connected to the outer wall of the guide rod 18 through the guide hole 17, and the lower outer surface of the snap-fit pin 16 is elastically connected to the bottom of the mounting hole 15 through the compression spring 19; the outer wall of the snap-fit pin 16 is slidably connected to the mounting hole 15; the outer wall of the insert block 14 is inserted into the slot 12, and the upper outer wall of the snap-fit pin 16 is snapped into the snap-fit limiting hole 13.
[0027] It should be noted that this utility model is a water quality testing and extraction device. The sampling cup 1 and telescopic rod 8 described herein are both existing technologies and can be readily understood by those skilled in the art; therefore, further details are omitted. A counterweight 2 is provided at the lower part of the sampling cup 1, and the lifting lug 3 at the upper part of the sampling cup 1 is rotatably connected to the connecting shaft 5. Therefore, due to the influence of the counterweight 2, the opening of the sampling cup 1 can face upwards, facilitating sampling. During assembly of the sampling cup 1, the clamping pin 16 is squeezed. The snap-fit pin 16 presses against the compression spring 19 along the mounting hole 15. The snap-fit pin 16 slides along the guide rod 18 through the guide hole 17, so that the upper end of the snap-fit pin 16 enters the mounting hole 15. Then, the insert block 14 is inserted into the slot 12. When the snap-fit pin 16 reaches the lower part of the snap-fit limiting hole 13, the reaction force of the compression spring 19 drives the upper part of the snap-fit pin 16 to snap into the snap-fit limiting hole 13, realizing the snap-fit assembly of the sampling cup 1. It is easy to disassemble and the operation process is simple.
