Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.
[0021] Embodiment one: please refer to Figures 1-3 An environmental monitoring sample storage tube, comprising a tube body 1, an observation window 2 is arranged on the surface of the tube body 1, a first tube cover 3 is arranged on the top of the tube body 1, a first opening 4 is arranged on the surface of the first tube cover 3, a second tube cover 5 is rotatably arranged on the surface of the first tube cover 3, a second opening 6 is arranged on the surface of the second tube cover 5, through the arrangement of the first opening 4 and the second opening 6, when the first opening 4 and the second opening 6 are coincident, the user can take out the liquid sample in the tube body 1 through the opening, which is convenient for the user to carry out subsequent detection, the clamping mechanism 7 is arranged on the surface of the tube body 1, through the arrangement of the clamping mechanism 7, when it is needed to collect and store the solid sample, the first tube cover 3 can be opened through the clamping mechanism 7, then the solid sample is put in, and then the first tube cover 3 is closed through the clamping mechanism 7, which facilitates the taking out and putting in of the solid sample.
[0022] A rotating groove 31 is arranged on the surface of the first tube cover 3, through the arrangement of the rotating groove 31, the second tube cover 5 can be rotated on the surface of the first tube cover 3 and can be fixedly arranged on the surface of the first tube cover 3, the rubber block 32 is fixedly arranged on the surface of the first tube cover 3 and is located at the edge close to the first opening 4, through the arrangement of the rubber block 32, when the first opening 4 and the second opening 6 are closed through the rotation of the second tube cover 5, the rubber block 32 on the surface of the first tube cover 3 contacts the bottom of the second tube cover 5, which increases the sealing property.
[0023] The bottom inner wall of the second tube cover 5 is fixedly provided with a rotating block 51. The rotating groove 31 and the rotating block 51 are engaged with each other through the arrangement of the rotating block 51, so that the first tube cover 3 and the second tube cover 5 can be rotated and fixed. The surface of the second tube cover 5 is fixedly provided with a plurality of anti-skid protrusions 52. The anti-skid protrusions 52 can increase the friction when the second tube cover 5 is rotated, so as to prevent hand slipping.
[0024] The size of the first opening 4 on the surface of the first tube cover 3 is smaller than that of the second opening 6 on the surface of the second tube cover 5. Through the size difference between the two openings, the second tube cover 5 and the first tube cover 3 can form a seal.
[0025] Specifically, when the liquid sample needs to be sampled, the operator first holds the second tube cover 5 and then twists the second tube cover 5 forward and the first tube cover 3 backward. At this time, the rotating block 51 in the inside slides in the rotating groove 31 in the inside. When the second tube cover 5 and the first tube cover 3 are rotated to the appropriate position, the second opening 6 on the surface is opposite to the first opening 4 at the bottom. In this way, the tube body 1 is opened. Then the operator uses a rubber-tipped dropper to suck the liquid sample and then drips the liquid sample into the first opening 4 and the second opening 6 to complete the sampling. Then the second tube cover 5 is twisted forward and the first tube cover 3 is twisted backward again until the second tube cover 5 and the first tube cover 3 are rotated to the first opening 4 and the second opening 6 are completely closed, and the sealing of the tube body 1 is completed.
[0026] Further, when the second tube cover 5 and the first tube cover 3 are rotated and closed, the rubber block 32 on the surface of the first tube cover 3 is in contact with the bottom of the second tube cover 5, which further increases the sealing performance of the tube body 1.
