Description

Technical Field

[0001] This utility model relates to the field of storage device technology, and in particular to a sample storage device for wastewater testing. Background Technology

[0002] Wastewater testing sample storage devices are specifically designed for preserving wastewater samples after collection. Their core function is to provide a stable, safe, and easily manageable environment to ensure the relative stability of the physical and chemical properties of wastewater samples throughout the entire process from collection to analysis, thereby ensuring the accuracy and reliability of test results. These devices typically consist of a storage tank, sample racks, a sealing system, and possible auxiliary facilities such as temperature control and light protection, designed to meet the specific sample storage requirements of different wastewater testing projects.

[0003] In practical wastewater testing, sampling tubes, as the direct containers holding wastewater samples, are crucial for sample protection due to their stability and safety. However, traditional storage methods often involve simply placing sampling tubes inside a storage box without proper securing measures. This allows the tubes to easily shake, potentially causing breakage, sample leakage, and contamination. Furthermore, collisions between tubes can lead to breakage, affecting sample purity and the accuracy of test results. Therefore, a wastewater testing sample storage device is needed to address these issues. Utility Model Content

[0006] To achieve the above objectives, one embodiment of this utility model provides a sample storage device for wastewater testing, including a box body. A box cover is rotatably connected to the back of the box body via a hinge. The front of the box cover is snapped into the box body via a snap-fit ​​assembly. Two top plates are bolted to the inner wall of the box body. Each top plate has several through holes on its top surface. A connecting frame is fixedly connected between the two top plates.

[0025] As an optional technical solution of this utility model, a number of limiting sleeves 15 are fixedly connected to the bottom surface of the top plate 3. The through hole 4 and the rubber base 11 are vertically corresponding to the limiting sleeves 15. The inner diameter of the limiting sleeve 15 is equal to the diameter of the through hole 4.

[0026] As an optional technical solution of this utility model, the top surface of the connecting frame 5 has two connecting holes 16. The two connecting rods 6 are slidably connected to the connecting frame 5 through the two connecting holes 16. The bottom of the connecting rod 6 is located inside the spring 9. Pulling the pull plate 7 upward can drive the lifting plate 8 to move upward through the transmission of the connecting rod 6, which can drive the sampling tube to move upward until the top of the sampling tube is exposed, so that the sampling tube can be easily taken out.

The limiting sleeve 15 can limit the tube body of the sampling tube until the bottom of the sampling tube is embedded in the rubber base 11.

[0033] 2): Cover the box with the lid 2 and use the snap fastener assembly to snap it into the box body 1. At this time, the threaded post 12 can be twisted to make it rotate relative to the lid 2. Through the threaded transmission, the pressure plate 13 can be driven to move downward until the bottom surface of the pressure plate 13 is in contact with the top surface of the top plate 3. Then the rubber pressure block 14 will be inserted into the through hole and squeeze the top of the sampling tube.

[0034] 3) When the sampling tube is taken out, reverse the threaded column 12 to make it move the pressure plate 13 upward until the rubber pressure block 14 moves out of the through hole 4.

The threaded post 12 can then be rotated relative to the lid 2, causing the pressure plate 13 to move downwards via the threaded drive until the pressure plate 13... After the bottom surface is attached to the top surface of the top plate 3, the rubber pressure block 14 will be inserted into the through hole and squeeze the top of the sampling tube to fix the sampling tube and prevent the tubes from colliding and breaking. When the sampling tube is taken out, reverse the threaded column 12 to make it move the pressure plate 13 upward until the rubber pressure block 14 moves out of the through hole 4. Then open the box cover 2 and pull the pull plate 7 upward. Through the transmission of the connecting rod 6, the lifting plate 8 can be moved upward, which can move the sampling tube upward until the top of the sampling tube is exposed, which makes it easy to take out the sampling tube.
