[0002] Water quality testing is the testing of water body quality, and the water body includes not only water, but also suspended matter, bottom sediment and aquatic organisms coexisting in the water. After the sewage is sampled, the samples need to be stored, usually placed in a storage box and then carried.

[0003] Although traditional storage boxes can fix test tubes, the samples inside the test tubes will precipitate after being left stationary for a long time. The existing storage boxes cannot mix the samples inside the test tubes evenly before the test tubes are taken out. However, directly testing them will cause deviations in the test results. Shaking the test tubes one by one to mix the substances inside the samples evenly will cause a sharp increase in the workload of the testers and increase the intensity of the testing work.

[0007] Furthermore, the connecting mechanism includes a plurality of groups of movable columns fixedly connected to both sides of the partition, and movable grooves are provided on the upper outer surface of the storage box near both sides, a guide rod is fixedly connected to the inside of the movable groove near one side, and a slider is movably connected to the outer surface of the guide rod, a support rod is hinged on the upper outer surface of the slider, and the end of the support rod away from the slider is hinged to the box cover.

[0008] Furthermore, a movable plate is movably connected to a position inside the movable groove on one side of the guide rod, and one end of the movable column is fixedly connected to the partition, and the other end passes through the interior of the movable groove and is fixedly connected to the movable plate, and the movable column is movably connected to the movable groove.

[0009] Furthermore, a plurality of groups of teeth 1 are fixedly connected at equal distances to one side of the outer surface of the movable plate close to the slider, and teeth 2 are hingedly connected to the outer surface of one side of the slider, and the teeth 1 and teeth 2 in the two groups of movable grooves are not engaged at the same time.

[0023] A limiting mechanism 7 for fixing the test tube storing the sample is arranged inside the receiving groove 5; the limiting mechanism 7 includes an annular elastic ring 701, and the elastic ring 701 is fixedly connected to the inside of the receiving groove 5, and a plurality of groups of limiting rings 702 are fixedly connected to the inner surface of the elastic ring 701 at equal distances, and the thickness of the limiting ring 702 increases from top to bottom, thereby increasing the resistance of the test tube to move in the direction of being drawn out of the receiving groove 5, and a buffer cavity 703 is formed between the inside of the elastic ring 701 and the receiving groove 5, and an annular airbag 704 is arranged inside the buffer cavity 703, and the annular airbag 704 is used to increase the buffering capacity of the elastic ring 701, and the annular airbag 704 is fixedly connected to the elastic ring 701 and the buffer cavity 703.

[0024] Embodiment 2:

[0025] like Figure 1-4 As shown, the difference between this embodiment and embodiment 1 is that when it is necessary to take out the test tube, the lock is opened and the box cover 2 is flipped up to one side, and a connecting mechanism 6 for driving the partition 4 to swing is arranged between the box cover 2 and the storage box 1, and the connecting mechanism 6 includes a plurality of groups of movable columns 601 fixedly connected to both sides of the partition 4, and movable grooves 602 are provided on the upper outer surface of the storage box 1 near both sides, and a guide rod 603 is fixedly connected to a position near one side inside the movable groove 602, and a slider 604 is movably connected to the outer surface of the guide rod 603, and a support rod 605 is hinged on the upper outer surface of the slider 604, and the end of the support rod 605 away from the slider 604 is hinged to the box cover 2, and during the flipping process of the box cover 2, the support rod 605 pulls the slider 604 to move along the guide rod 603.

[0026] A movable plate 606 is movably connected to the movable groove 602 at a position on one side of the guide rod 603, and one end of the movable column 601 is fixedly connected to the partition 4, and the other end passes through the movable groove 602 and is fixedly connected to the movable plate 606, and the movable column 601 is movably connected to the movable groove 602; a plurality of groups of teeth 1 607 are equidistantly fixedly connected to one side of the outer surface of the movable plate 606 close to the slider 604, and a tooth 2 608 is hinged on the outer surface of one side of the slider 604, and the teeth 1 607 and the teeth 2 608 in the two groups of movable grooves 602 are not engaged at the same time. Therefore, during the movement of the slider 604, the two groups of movable plates 606 repeatedly push the movable column 601 respectively, and the partition 4 drives the test tube to shake slightly under the repeated push and pull of the movable column 601.

[0027] The working process and principle of the utility model are as follows:

[0028] Step 1: Place the test tube containing the water quality test sample into the mounting hole 8, and make the bottom of the test tube contact the protective cotton. The rubber ring and the elastic ring 701 elastically fix the test tube, thereby ensuring the stability of the test tube and preventing the test tube from having a hard collision with the partition 4 and the support plate 3. In addition, the annular airbag 704 can improve the buffering capacity of the elastic ring 701.

[0029] Step 2: Then cover the box cover 2 and fix the box cover 2 with a lock. When the test tube needs to be taken out, open the lock and flip the box cover 2 to one side. During the flipping process of the box cover 2, the support rod 605 pulls the slider 604 to move along the guide rod 603;

[0030] Step three, since the tooth 1 607 and the tooth 2 608 inside the two sets of movable grooves 602 are not engaged at the same time, during the movement of the slider 604, the two sets of movable plates 606 repeatedly push the movable column 601 respectively, and the partition 4 drives the test tube to shake slightly under the repeated pushing and pulling of the movable column 601, so that the precipitation formed inside the test tube due to long-term standing is evenly mixed inside the sample, and there is no need for the staff to shake the test tubes one by one.
