[0024] See also Figure 1 、 Figure 2 、 Figure 3 and Figure 4 The utility model provides a sample placement test tube for water quality detection, including a sample placement test tube body 1 and a sealing cover 2. The top of the sample placement test tube body 1 is an open structure, and the sealing cover 2 is arranged on the top of the sample placement test tube body 1. The sample placement test tube body 1 is used to hold the collected water quality sample, and the sealing cover 2 is used to seal the top opening of the sample placement test tube body 1. During the carrying process, the water quality sample can be prevented from spilling out of the sample placement test tube body 1. When replenishment is needed, the explosion-proof membrane on the outer wall of the sample placement test tube body 1 is used to protect the sample placement test tube body 1. The structural composition of the explosion-proof membrane has been disclosed in the patent document of a sample placement test tube for water quality detection disclosed by the authorization announcement number CN220258076U, so it will not be repeated in this article. Among them:

[0025] The sealing cover 2 includes a circular cover plate 21, an inner blocking column 22, an outer annular sleeve 23, a sealing assembly and a rubber suction cup 24. The circular cover plate 21 is located at the top of the sample test tube body 1, and the inner blocking column 22 is fixedly installed at the bottom center of the circular cover plate 21. The bottom of the inner blocking column 22 extends into the sample test tube body 1. The outer annular sleeve 23 is fixedly installed at the bottom of the circular cover plate 21. The outer diameter of the outer annular sleeve 23 is the same as the outer diameter of the circular cover plate 21. The top of the sample test tube body 1 extends into the outer annular sleeve 23. The bottom of the inner blocking column 22 passes through the outer annular sleeve 23. The sealing assembly is arranged on the circular cover plate 21 and the sample test tube body 1. The sealing assembly includes an annular sealing gasket 25, a first sealing ring 26 and a second sealing ring 27. The annular sealing gasket 25 is fixedly mounted on the bottom of the circular cover 21. The bottom of the annular sealing gasket 25 is in sealing contact with the top of the sample placement test tube body 1. The first sealing ring 26 is fixedly sleeved on the outer wall of the inner blocking column 22. The outer ring of the first sealing ring 26 is in sliding sealing contact with the inner wall of the sample placement test tube body 1. The second sealing ring 27 is fixedly mounted on the inner ring wall of the outer annular sleeve 23. The inner ring of the second sealing ring 27 is in sliding sealing contact with the outer wall of the sample placement test tube body 1. The annular sealing gasket 25 can play a role in the circular sealing. The first sealing ring 26 is used to seal the gap between the inner wall of the sample test tube body 1 and the inner blocking column 22, and the second sealing ring 27 is used to seal the gap between the outer annular sleeve 23 and the outer wall of the sample test tube body 1, thereby achieving the purpose of triple sealing, so that the sealing cover 2 has a good sealing performance when sealing the top opening of the sample test tube body 1, and will not leak or seep liquid. It should be noted that the annular sealing gasket 25, the first sealing ring 26 and the second sealing ring 27 are all made of existing good elasticity, wear resistance and The rubber suction cup 24 is made of corroded rubber material, and is fixedly installed on the top of the circular cover 21. By utilizing the self-adsorption characteristics of the rubber suction cup 24, the sample placement test tube body 1 can be turned upside down so that the sealing cover 2 is adsorbed and fixed on the horizontal platform surface. Therefore, when there is no test tube rack, the sample placement test tube body 1 can be conveniently and stably placed, and the sample placement test tube body 1 will not roll down and fall to the ground and break. The number of rubber suction cups 24 is set to two, and the two rubber suction cups 24 are symmetrically arranged on both sides of the knob 5. By setting up two rubber suction cups 24 for joint use, the stability of the sample placement test tube body 1 when it is fixed can be enhanced.

[0026] In this embodiment, the inner diameter of the annular sealing gasket 25 is set to be the same as the inner diameter of the sample test tube body 1, and the outer diameter of the annular sealing gasket 25 is larger than the outer diameter of the sample test tube body 1, which can ensure that the gap between the circular cover 21 and the top of the sample test tube body 1 is effectively sealed.

[0027] In this embodiment, the number of the first sealing rings 26 is not less than two, and the number of the second sealing rings 27 is not less than two, so as to further improve the sealing effect of the sealing cover 2 on the top opening of the sample-carrying test tube body 1.

[0028] In this embodiment, a first vertical hole is provided on the top of the circular cover plate 21, and a second vertical hole is provided on the top of the inner blocking column 22. The second vertical hole is connected to the first vertical hole, and a vertical rod 3 is rotatably installed in the second vertical hole through a sealed bearing. The bottom end of the vertical rod 3 extends into the sample placement test tube main body 1, and a plurality of evenly distributed stirring rods 4 are fixedly installed on the vertical rod 3. The top end of the vertical rod 3 passes through the first vertical hole and is fixedly installed with a knob 5. The knob 5 is used to facilitate the rotation of the vertical rod 3 and the plurality of stirring rods 4. The plurality of stirring rods 4 can be used to stir the water quality sample stored in the sample placement test tube main body 1 to avoid the precipitation of impurities in the water quality sample and the resulting inaccurate test results, thereby effectively replacing the method of shaking the sample placement test tube main body 1 by hand to avoid the phenomenon that the sample placement test tube main body 1 slips out of the hand during the hand-held shaking process.

[0029] The bottle cap 2 is convenient to install and can be used for the sample test of the present invention. The inner ring of the sample placement test tube body 1 slides downward on the outer wall of the sample placement test tube body 1. When the annular sealing gasket 25 drops to tightly contact the top of the sample placement test tube body 1, the sealing cover 2 is firmly and effectively installed on the top of the sample placement test tube body 1. During the carrying process, the water sample in the sample placement test tube body 1 will not spill or seep out. When there is no test tube rack in the office, just turn the sample placement test tube body 1 upside down so that the sealing cover 2 is vertically facing downward, and then use two rubber suction cups 24 to firmly adsorb and fix it on the horizontal On the table, the sample can be placed on the test tube body 1 stably and fixedly without causing the sample test tube body 1 to roll off. When the sample test tube body 1 needs to be removed, the two rubber suction cups 24 can be squeezed to release the adsorption and fixation of the two rubber suction cups 24 on the horizontal table surface. Before pouring out the water sample, the knob 5 is rotated, and the knob 5 drives the vertical rod 3 and the stirring rod 4 to rotate, so that the water sample can be stirred evenly to avoid the precipitation of impurities in the water sample. Then the sealing cover 2 can be pulled out, and the water sample can be poured out for testing.
