Description

Technical Field

[0001] The utility model relates to the technical field of environmental protection and chemical analysis, in particular to a test tube storage rack for detecting the digestion process of total phosphorus and total nitrogen. Background Art

[0002] In environmental monitoring and chemical analysis, accurate detection of the digestion process of total phosphorus and total nitrogen is a key step to ensure water quality safety. During the digestion process, the storage and management of test tubes are crucial to the accuracy of experimental results. However, the existing test tube storage racks still have the following problems in actual use:

[0003] Patent No. "CN202320743807.9" discloses a test tube storage rack. When the device is in use, the test tube bottles are placed in the placement grooves respectively. The utility model is provided with a first label at the outer end of the fixed frame, and a second label is provided on the fixed frame beside each observation port. In this way, a row of test tube bottles on each sliding seat can be classified and marked, and each test tube bottle can also be classified and marked. When the test tube bottle needs to be observed or taken, the limit block is rotated to make the limit block disengage from the sliding seat, so that the sliding seat can move on the base, and the fixed frame is pulled outward, and the limit slider and the limit slide groove are in the position of the limit slider and the limit slide groove. Under the action, the sliding seat moves outward on the base, so that the fixing frame slides outward with the sliding seat, and the corresponding test tube bottle is pulled out separately through the cooperation of the sliding seat and the fixing frame. In this way, the pulled out test tube bottle can be observed intuitively, so there is no need to take the test tube bottle out. During use, the device cannot keep the test tube bottle warm, resulting in differences in the temperature of the test tube bottle during the observation process, resulting in inaccurate observation data, making the device less practical. In addition, during use, the device will affect other placed test tube bottles in the process of taking out the test tube bottle, which may easily cause dust and other objects to fall into the inside of the other placed test tube bottles, and the practicality is poor.

[0026] The constant temperature mechanism 2 includes a heat conducting plate 21, a first connecting block 22, a bolt 23 and a heating controller 24. Two heat conducting plates 21 are symmetrically arranged on the side of the base 1. The sides of the two heat conducting plates 21 are each provided with a first connecting block 22. The two first connecting blocks 22 are connected by bolts 23. The sides of the heat conducting plates 21 are connected with a heating controller 24.

During use, the heat conducting plates 21 are heated by the heating controller 24, so that the heat conducting plates 21 transmit the temperature to the base 1, so that the liquid stored inside the base 1 is kept at a constant temperature, which is convenient for observation and research.

[0027] The rotating mechanism 3 includes a connecting seat 31, a driving motor 32 and a clamping block 33.

[0035] The test tube body 7 pushes two symmetrically arranged limit clamps 47 on the inner side of the card slot 42. When the limit clamps 47 are squeezed, the limit clamps 47 squeeze the telescopic rod 45 and the spring column 46 at the same time. When the test tube body 7 reaches the inner side of the card slot 42, the spring column 46 pushes the telescopic rod 45, and the telescopic rod 45 pushes the limit clamps 47 to reset. At this time, the limit clamps 47 limit the test tube body 7. At this time, the test tube body 7 can be vertically placed in the test tube storage hole 6.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
