A sample storage device for ecological environment monitoring

Abstract

This utility model relates to the field of power distribution box technology, specifically to a sample storage device for ecological environment monitoring, including a storage box. The storage box has an internal clamping mechanism, and the bottom of the clamping mechanism has a bottom-supporting protection mechanism. The advantages are as follows: when a sample container is placed inside the storage box, the spring telescopic rods on both sides push the upper and lower racks to move towards each other, causing the extension plate to clamp the container, achieving compatibility with non-standard sampling equipment containers. When it is necessary to remove the sample container, the storage cover is pulled open, causing the handle to rotate until the push block drives the transmission rod to rotate, causing the gears and racks to move the two clamping plates. This allows the pull rope to move the bottom-supporting plate upwards to the top, pushing the sample container out from between the extension plates, achieving rapid removal of the placed sample container.

Description

Technical Field

[0001] This utility model relates to the field of power distribution boxes, specifically a sample storage device for ecological environment monitoring. Background Technology

[0002] Environmental monitoring stations, research institutions, field sampling sites, and laboratory analysis processes all require the preservation of various environmental samples (such as water samples, soil samples, gas samples, and microbial cultures) to ensure their stability before collection, transportation, and analysis. Sample storage boxes are typically used for preservation, their core function being to reduce the risk of degradation or contamination during storage, thereby ensuring the accuracy of monitoring data.

[0003] Existing sample storage devices for ecological and environmental monitoring often adopt fixed partition structures: containers of different sizes are partitioned and positioned by pre-set slots, partitions or fixed frames to reduce shaking during transportation. These designs have problems such as complex structure and insufficient flexibility, and cannot fully meet the needs of rapid deployment and personalization in multiple scenarios.

[0004] The existing container placement technology has the following main problems: there is a contradiction between structural stability and versatility. Although the pre-set partition structure can fix the container, it has poor compatibility with non-standard containers or temporarily replaced sampling equipment, requiring frequent adjustment and replacement of parts. In addition, some sample containers are long, requiring slow and careful placement and difficult removal, which takes a long time. Utility Model Content

[0017] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0018] Please see the appendix Figure 1-7 This application provides the following technical solutions.

[0019] An ecological environment monitoring sample storage device includes a storage box 1. The storage box 1 has a clamping mechanism 2 inside, and a bottom support and protection mechanism 3 at its bottom. The storage box 1 includes a storage box body 11, with four slide rails 12 on its inner wall. The clamping mechanism 2 includes two clamping plates 26, placed vertically in opposite directions. Racks 24 are fixedly connected to both sides of each clamping plate 26. Several rollers 25 are rotatably connected to one side of each rack 24, and the rollers 25 are movably connected to the inner wall of the slide rails 12. A fixing plate 15 is fixedly connected to the inner wall of the storage box body 11. Several slots 17 are formed through the top of the fixing plate 15. Several clamping grooves 28 are formed through the top of each clamping plate 26, and each clamping groove corresponds to one of the slots 17 on the top of the fixing plate 15. The walls are fixedly connected with extension plates 29. Several spring telescopic rods 27 are fixedly connected to the opposite sides of the two clamping plates 26. The ends of the spring telescopic rods 27 away from the clamping plates 26 are fixedly connected to the inner wall of the storage box body 11. The four racks 24 are divided into two groups. The two racks 24 in each group are placed up and down in opposite directions. The opposite sides of the two racks 24 in each group are meshed with gears 23. The middle of the two gears 23 is fixedly connected with a transmission rod 21. The two ends of the transmission rod 21 are rotatably connected to the storage box body 11. The two ends of the transmission rod 21 are rotatably connected to the outer wall of the storage box body 11. A push block 210 is fixedly connected to one side of the rotation handle 22. Rotating wheels 211 are fixedly connected to the two ends of the transmission rod 21. A limit groove 212 is opened through the side wall of the rotating wheel 211. The inner wall of the limit groove 212 is slidably connected to the push block 210.

[0020] It should be noted that when placing the sample container, the operator rotates the storage cover 13 to open it, causing the rotating handle 22 to rotate, which in turn causes the push block 210 to rotate inside the limiting groove 212 until the push block 210 drives the rotating wheel 211 to rotate, which in turn drives the limiting groove 212 to rotate. The limiting groove 212 drives the transmission rod 21 to rotate, which in turn drives the gear 23 to rotate. Through the meshing of the gear 23 and the rack 24, the upper and lower racks 24 are moved to both sides, causing the two clamping plates 26 to slide to both sides on the inner wall of the slide rail 12 via the rollers 25, until the clamping grooves 28 on the two clamping plates 26 form corresponding slots 17 on the fixed insertion plate 15, allowing the sample container to be inserted. At this time, the storage cover 14 is closed, and the spring telescopic rod 27 releases its elastic potential energy to push the two clamping plates 26 to move towards each other and reset, until the extension plate 29 clamps the sample container. The anti-slip pad increases the friction, thus fixing the container.

[0021] The bottom support protection mechanism 3 includes a sliding damping rod 35. Both ends of the sliding damping rod 35 are fixedly connected to the inner wall of the storage box body 11. A scissor-type adjusting rod 34 is slidably connected to the outer wall of the sliding damping rod 35. A bottom support plate 32 is rotatably connected to the top of the scissor-type adjusting rod 34. Several bottom-drag grooves 33 are formed on the top of the bottom support plate 32, each corresponding to a number of slots 17. Through slots are formed on both sides of the fixed insert plate 15 and the tops of the two clamping plates 26. Pull ropes 31 are fixedly connected to both ends of the top of the bottom support plate 32. The two pull ropes 31 pass through the fixed insert plate 15. The slots on the fixed insertion plate 15 and the clamping plate 26 are connected to a guide roller 16 movably in the middle of the outer wall of the pull rope 31. One side of the guide roller 16 is rotatably connected to the fixed insertion plate 15. The top of the storage box body 11 is rotatably connected to the storage cover 13. The ends of the two pull ropes 31 away from the bottom plate 32 are fixedly connected to the storage cover 13. The top of the storage cover 13 is rotatably connected to a rotating pull ring 14. A spring buckle 4 is fixedly connected to one side of the storage box body 11. When the storage cover 13 and the storage box body 11 are closed, the rotating pull ring 14 is engaged with the spring buckle 4.

[0022] It should be noted that while the handle 22 is turned, the storage cover 13 pulls the pull rope 31. The pull rope 31 passes through the through slots opened on the fixed insert plate 15 and the clamping plate 26. Guided by the guide roller 16, the friction is reduced, and the bottom plate 32 is pulled upward. The scissor-type adjusting rod 34 slides on the sliding damping rod 35 until the bottom plate 32 reaches the top. The sample container placed inside the storage box body 11 can be lifted up, making it easy for the operator to take it out. At the same time, the sample container can be inserted from the slot 17 until the bottom of the sample container reaches the bottom groove 33. After the sample container is placed, the storage cover 13 is slowly closed, and the bottom plate 32 falls to the bottom of the storage box body 11, allowing the sample container to enter the storage box body 11. Finally, the rotating pull ring 14 is locked into the spring buckle 4, completing the storage of the sample.

[0023] When placing the sample container, the operator rotates the storage cover 13 to open it, causing the rotating handle 22 to rotate. This causes the push block 210 to rotate inside the limiting groove 212 until the push block 210 drives the rotating wheel 211 to rotate. The rotating wheel 211 then drives the limiting groove 212 to rotate, which in turn drives the transmission rod 21 to rotate. The transmission rod 21 then drives the gear 23 to rotate. Through the meshing of the gear 23 and the rack 24, the upper and lower racks 24 move to both sides, causing the two clamping plates 26 to slide to both sides on the inner wall of the slide rail 12 via the rollers 25. This continues until the clamping grooves 28 on the two clamping plates 26 form corresponding slots 17 on the fixed insert plate 15. At this time, the spring inside the spring telescopic rod 27 contracts. While rotating the handle 22, the storage cover 13 pulls the pull rope 31, which passes through the fixed insert plate. The through slots on the clamping plate 26 and the guide roller 16 reduce friction, pulling the bottom plate 32 upward. The scissor-type adjusting rod 34 slides on the sliding damping rod 35 until the bottom plate 32 reaches the top, which can lift the sample container placed inside the storage box body 11, making it easy for the operator to take it out. At the same time, the sample container can be inserted from the slot 17 until the bottom of the sample container reaches the bottom groove 33. After the sample container is placed, the storage cover 13 is slowly closed, and the bottom plate 32 falls to the bottom of the storage box body 11, allowing the sample container to enter the storage box body 11. The spring telescopic rod 27 releases elastic potential energy to push the two clamping plates 26 to move towards each other and reset until the extension plate 29 clamps the sample container. The anti-slip pad increases the friction to fix it. Finally, the rotating pull ring 14 is locked into the spring buckle 4 to complete the storage of the sample.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
