[0027] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0028] like Figure 1-7As shown, an environmental monitoring sample storage device includes a housing 1 and a storage mechanism disposed within the housing 1. A coil 10 is disposed around the outer periphery of the storage mechanism, and the coil 10 is connected to a refrigeration device 9 disposed within the housing 1.

[0029] The storage mechanism includes an inner ring column 2, an adjusting plate 3, an elastic pushing mechanism 5, and a cover plate 6. The adjusting plate 3 is located on the upper side inside the inner ring column 2. The elastic pushing mechanism 5 is located inside the housing 1 and at the center of the inner ring column 2 and the adjusting plate 3. Multiple circumferentially distributed receiving frames 4 are provided inside the inner ring column 2. The multiple receiving frames 4 are all located on the adjusting plate 3. The cover plate 6 is located on the upper side of the multiple receiving frames 4 and is connected to the inner ring column 2.

[0030] The elastic push mechanism 5 includes an inner and outer threaded ring column 51, a push spring 53, a push plate 54, and an adjusting rod 55. The inner and outer threaded ring column 51 is fixed to the bottom surface of the housing 1 and is located at the center of the inner ring column 2. A guide tube 52 is provided inside the inner ring column 2, and the lower side of the guide tube 52 is threaded with the outer wall of the inner and outer threaded ring column 51 through an internal spiral thread. The push spring 53 is sleeved on the outer circumference of the guide tube 52 and is located between the push plate 54 and the bottom surface of the housing 1. The push plate 54 is set on the guide tube 52 and the adjusting rod 55, and is located below one of the receiving frames 4.

[0031] As an optional implementation, an externally expanded threaded head 55a is integrally provided on the lower side of the adjusting rod 55. The adjusting rod 55 is disposed inside the guide tube 52, and the externally expanded threaded head 55a on the lower side is threadedly engaged with the inner wall of the internal and external threaded ring column 51. A balance sleeve 54a is slidably sleeved on the outer periphery of the guide tube 52, and the balance sleeve 54a is fixed on one side of the upper push plate 54. A blocking ring 54b and a positioning ring 54c are slidably disposed inside the guide tube 52. The positioning ring 54c is slidably sleeved on the adjusting rod 55, and the blocking ring 54b is disposed above the positioning ring 54c and fixed on the adjusting rod 55. In this way, the adjusting rod 55 can not only be pushed and pulled up and down, but also restricted after downward movement, so that the elastic pushing mechanism 5 is in an energy storage state when in use.

[0032] See attached document Figure 6 and attached Figure 7 Two sliders are fixed on the outer periphery of the positioning ring 54c, and the two sliders are respectively slidably engaged with two sliding holes 52a. The balance sleeve 54a is fixed on the two sliders. The two sliders press on the upper side of the push spring 53. In this way, the positioning ring 54c can be pushed by the push spring 53, which drives the push plate 54 to push the receiving frame 4 upward.

[0033] See attached document Figure 3 and attached Figure 4An overlapping ring 22 is fixedly provided on the upper side of the inner wall of the inner ring column 2. The adjusting plate 3 is movably sleeved in the inner ring column 2 and overlaps on the overlapping ring 22. The adjusting plate 3 has multiple circumferentially distributed insertion interfaces 31. The receiving frame 4 is fitted with the insertion interface 31. The multiple insertion interfaces 31 are evenly spaced at 45° intervals, so that the multiple receiving frames 4 are evenly distributed in the inner ring column 2, which facilitates the cyclic storage and retrieval operation.

[0034] Furthermore, the overlapping ring 22 is provided with two round rollers 7, and the two round rollers 7 are respectively locked in two positioning semi-circular grooves 22a. The two round rollers 7 are engaged with multiple circumferentially distributed movable semi-circular grooves 3a. The outer circumference of the round rollers 7 is coated with lubricating oil. The multiple movable semi-circular grooves 3a are circumferentially opened on the outer circumference of the adjusting plate 3. The multiple movable semi-circular grooves 3a are distributed at intervals of 45°. In this way, when the receiving frame 4 is rotated, the round rollers 7 can be positioned and locked, thereby improving the rotation positioning effect of the receiving frame 4.

[0035] Furthermore, an outer expansion ring 21 is fixed on the upper side of the inner ring post 2, and a sealing gasket 62 is provided on the outer expansion ring 21. Multiple circumferentially distributed screws pass through the cover plate 6 to press the sealing gasket 62 onto the outer expansion ring 21. This facilitates the sealing when installing the cover plate 6, thereby improving the sealing effect after installation.

[0036] Furthermore, an inner insert ring 61 is fixedly provided at the center of the cover plate 6. The inner insert ring 61 is inserted into the outer ring post 32. The outer ring post 32 is fixed on the adjusting plate 3. The adjusting rod 55 moves through the adjusting plate 3 and the cover plate 6, and a torsion ring is fixed on its upper side. Two symmetrical torsion plates 33 are provided inside the inner insert ring 61, and the two torsion plates 33 are fixed on the surface of the adjusting plate 3. In this way, the adjusting rod 55 can be rotated or pushed and pulled up and down by the torsion ring, thereby cooperating with the two torsion plates 33 to rotate the adjusting plate 3 and realize the rotation positioning and upward push of a certain receiving frame 4.

[0037] See attached document Figure 1 The cover plate 6 has an extraction hole, which corresponds to the upper push plate 54. A snap-fit ​​cover 8 is provided on the top of the cover plate 6, and the snap-fit ​​cover 8 is inserted into the extraction hole. The cover plate 6 is made of transparent material, so that when the extraction hole is not in use, the snap-fit ​​cover 8 can be used to snap and cover it, thereby preventing external impurities from entering the box 1 and affecting the quality of the sample.

[0038] Using the above structure, firstly, the torsion plate 33 drives the adjusting plate 3 to rotate, causing the movable semi-circular groove 3a on the outer periphery of the adjusting plate 3 to rotate and be engaged with the roller 7, thereby driving the receiving frame 4 to rotate to correspond with the extraction hole. Then, the adjusting rod 55 is rotated, causing the externally expanded threaded head 55a at the lower end of the adjusting rod 55 to rotate in conjunction with the internal thread of the internal and external threaded ring column 51, thereby disengaging the adjusting rod 55 from the internal and external threaded ring column 51. At this time, the downward adjusting rod 55 is pushed by the energy stored in the upward pushing spring 53, driving the upward pushing plate 54 to push the corresponding receiving frame 4 upward along the extraction hole, thereby facilitating the extraction of the sample from the upward-moved receiving frame 4. When storing, the operation is reversed. The receiving frame 4 containing the sample is aligned with the insertion interface 31 and pressed down. The upward pushing spring 53 is compressed to make the receiving frame 4 fully positioned, and the adjusting rod 55 is rotated to drive the externally expanded threaded head 55a to connect with the internal and external threaded ring column 51 to constrain the pushing of the upward pushing spring 53. After the operation is completed, the snap-fit ​​cover 8 is closed to maintain a sealed state. The entire operation process ensures that only one container 4 is exposed at a time, while the remaining samples are always kept in a closed storage environment.
