Description

Technical Field

[0001] This utility model relates to the field of soil microbiology research technology, specifically to a portable collection and preservation box for soil microbial samples suitable for arid regions. Background Technology

[0002] Extreme environments in arid regions have a significant impact on soil microbial activity. If samples are not properly preserved after collection, it can easily lead to changes in the microbial community structure, a decrease in metabolic activity, or inactivation of target strains. Preservation boxes can isolate external high temperatures through multi-layer insulation structures, maintain a low temperature environment below 5°C or even lower, and slow down the metabolic rate of microorganisms.

[0003] A sample preservation device for soil microbial community research, disclosed in patent publication number CN216862244U, includes a foam box, an outer box body fitted around the foam box, a lid at the top of the outer box body, and multiple storage tube racks arranged at equal intervals inside the foam box below the lid, with gaps between each storage tube rack. A movable window is opened on one side of the outer box body, which communicates with the inner cavity of the foam box. A movable plate is provided at the window of the movable window, and multiple dry ice storage boxes are provided on the side of the movable plate facing the foam box. Each dry ice storage box is placed below the gaps and staggered from each storage tube rack.

[0004] During the process of removing the storage tube rack, the user needs to reach into the outer box to pull out the storage tube rack. The storage tube rack may be difficult to pull out due to its tight arrangement. At the same time, the limited operating space for the hand to reach into the outer box will further increase the difficulty of pulling out the storage tube rack. In addition, improper force by the user may cause the storage tube to be overturned, resulting in sample leakage or contamination. Utility Model Content

[0005] To address the aforementioned shortcomings of existing technologies, this invention provides a portable collection and preservation box for soil microbial samples suitable for arid regions, which effectively solves the problem that storage tube racks may be difficult to remove due to their tightly packed arrangement in existing technologies.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0013] Furthermore, the lifting assembly includes multiple slide rails fixedly connected to the inner wall of the outer box, an arc-shaped block slidably connected to the inner surface of the slide rails, a roller that slides in contact with the arc surface of the arc-shaped block, a magnetic suction frame fixedly mounted on the outer end face of the roller via a bearing and used to support the storage tube rack, a sliding sleeve fixedly connected to the bottom of the magnetic suction frame, and a limiting rod fixedly connected to the inner wall of the outer box and used in conjunction with the sliding sleeve.

[0014] Furthermore, the sliding sleeve is slidably fitted onto the outer surface of the limiting rod;

[0015] When the arc-shaped block moves along the inner surface of the slide rail, the roller can press the magnetic suction frame, thereby causing it to move the storage tube rack along the limiting rod to the outside of the outer box.

[0016] Furthermore, the force-applying component includes a fixed frame fixedly connected to the outside of the outer box, a plurality of first force-applying columns slidably connected to the inner surface of the fixed frame and used in conjunction with the arc-shaped block, and a first spring sleeved on the outside of the first force-applying columns.

[0017] Furthermore, the through end of the first force-applying column is fixedly connected to the outer surface of the arc-shaped block;

[0018] The first spring is fixedly installed on the outer surface of the first force-applying column, and its other end abuts against the inner wall of the fixed frame.

[0019] Furthermore, the positioning mechanism includes a sliding plate slidably connected to the inner wall of the fixed frame, a plurality of inclined grooves formed on the outer surface of the sliding plate, a first pressure block integrally formed on the inner surface of the first force-applying column and used in conjunction with the inclined grooves, a fixed column fixedly connected to the inner wall of the fixed frame, a second spring fixedly installed on the outer surface of the fixed column and used in conjunction with the sliding plate, and a limiting groove formed on the surface of the sliding plate and used in conjunction with the fixed column.

[0020] Furthermore, the outer end face of the second spring is fixedly connected to the outer surface of the sliding plate, and the outer surface of the fixing post is in sliding contact with the inner wall of the limiting groove.

[0021] Furthermore, the unlocking component includes a sloping straight groove formed on the outer surface of the sliding plate, a second force-applying column slidably connected to the inner surface of the fixed frame, a second pressure block integrally formed on the inner surface of the second force-applying column and used in conjunction with the sloping straight groove, and a third spring sleeved on the outer side of the second force-applying column.

[0022] Furthermore, the third spring is fixedly installed on the outer surface of the second force-applying column, and its other end abuts against the inner wall of the fixing frame.

[0023] The technical solution provided by this utility model has the following advantages compared with the known prior art:

[0024] This invention, by setting up a pop-out mechanism, not only allows the storage tube rack to be lifted to the outside of the outer box and locked simultaneously without the user having to put their hands inside when taking it out, but also allows the storage tube rack to be quickly reset by a second force column, and only allows a single storage tube rack to extend outward, preventing the storage tube from being overturned due to improper force by the user. This achieves the effect of ensuring the safety and convenience of sample retrieval and placement while ensuring the integrity of sample preservation. Attached Figure Description

Detailed Implementation

[0035] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0036] The present invention will be further described below with reference to the embodiments.

[0037] Example: A portable collection and preservation box for soil microbial samples suitable for arid regions, see attached document. Figure 1 - Appendix Figure 8 ,include,

[0038] The storage box body 100 includes an outer box 110, a plurality of storage tube racks 120 disposed inside the outer box 110, a sealing cover 130 hinged to the top of the outer box 110, and a locking member 140 fixedly installed on the outer surface of the outer box 110 and used in conjunction with the sealing cover 130.

[0039] It should be noted that the outer box 110 can form an inner and outer isolated cavity with the sealing cover 130, and with the help of multi-layer heat insulation materials, it can isolate the high temperature in the arid area. The storage tube rack 120 is used to place soil microbial sample tubes. After the sealing cover 130 is closed, it can be fixed by the locking member 140. The storage box body 100 is existing technology, and this solution will not describe it in detail. Moreover, those skilled in the art can clearly understand its working principle.

[0040] The pop-out mechanism 200 includes a lifting assembly 210 for controlling any storage tube rack 120 to move to the outside of the outer box 110, a force-applying assembly 220 for applying external force to the lifting motion of the lifting assembly 210, a positioning mechanism 230 for automatically locking the positions of the lifting assembly 210 and the force-applying assembly 220, and an unlocking assembly 240 for releasing the locking effect of the positioning mechanism 230.

[0041] The lifting assembly 210 is located inside the outer box 110, and its number corresponds to the storage tube rack 120.

[0042] The force application component 220 is located on the outside of the outer box 110, and its number corresponds to the lifting component 210;

[0043] The positioning mechanism 230 is located inside the lifting assembly 210. The positioning mechanism 230 only allows any one of the lifting assemblies 210 to lift the storage tube rack 120 to the outside of the outer box 110.

[0044] The unlocking component 240 is located on the outside of the positioning mechanism 230.

[0045] Specifically, the lifting assembly 210 includes multiple slide rails 211 fixedly connected to the inner wall of the outer box 110, an arc block 212 slidably connected to the inner surface of the slide rails 211, a roller 213 slidably in contact with the arc surface of the arc block 212, a magnetic suction frame 214 fixedly mounted on the outer end face of the roller 213 by bearings and used to support the storage tube rack 120, a sliding sleeve 215 fixedly connected to the bottom of the magnetic suction frame 214, and a limiting rod 216 fixedly connected to the inner wall of the outer box 110 and used in conjunction with the sliding sleeve 215.

[0046] Furthermore, the sliding sleeve 215 is slidably sleeved on the outer surface of the limiting rod 216;

[0047] When the arc block 212 moves along the inner surface of the slide rail 211, the roller 213 can press the magnetic suction frame 214, thereby causing it to move the storage tube rack 120 along the limiting rod 216 to the outside of the outer box 110.

[0048] Preferably, the force application component 220 includes a fixed frame 221 fixedly connected to the outside of the outer box 110, a plurality of first force application columns 222 slidably connected to the inner surface of the fixed frame 221 and used in conjunction with the arc block 212, and a first spring 223 sleeved on the outside of the first force application column 222.

[0049] It should be noted that the through end of the first force-applying column 222 is fixedly connected to the outer surface of the arc-shaped block 212;

[0050] The first spring 223 is fixedly installed on the outer surface of the first force-applying column 222, and its other end abuts against the inner wall of the fixed frame 221.

[0051] Furthermore, the positioning mechanism 230 includes a sliding plate 231 slidably connected to the inner wall of the fixed frame 221, a plurality of inclined grooves 232 formed on the outer surface of the sliding plate 231, a first pressure block 233 integrally formed on the inner surface of the first force-applying column 222 and used in conjunction with the inclined grooves 232, a fixed column 234 fixedly connected to the inner wall of the fixed frame 221, a second spring 235 fixedly installed on the outer surface of the fixed column 234 and used in conjunction with the sliding plate 231, and a limiting groove 236 formed on the surface of the sliding plate 231 and used in conjunction with the fixed column 234.

[0052] It should be noted that when the first force-applying column 222 is pressed, causing the first pressure-applying block 233 to move, the sliding plate 231 can be squeezed and slid along the inner wall of the fixed frame 221 through the inclined groove 232. When the first pressure-applying block 233 moves to the inclined end of the inclined groove 232, the second spring 235 will drive the sliding plate 231 to return to its original position through the reaction force, thereby limiting the first pressure-applying block 233 through the right-angle contour of its inner wall of the inclined groove 232.

[0053] Specifically, the outer end face of the second spring 235 is fixedly connected to the outer surface of the sliding plate 231, and the outer surface of the fixing post 234 slides in contact with the inner wall of the limiting groove 236.

[0054] Preferably, the unlocking component 240 includes a sloping straight groove 241 formed on the outer surface of the sliding plate 231, a second force-applying column 242 slidably connected to the inner surface of the fixed frame 221, a second pressure block 243 integrally formed on the inner surface of the second force-applying column 242 and used in conjunction with the sloping straight groove 241, and a third spring 244 sleeved on the outer side of the second force-applying column 242.

[0055] It should be explained that when the second force-applying column 242 is pressed, causing the second pressure-applying block 243 to move, the second pressure-applying block 243 can squeeze the sliding plate 231 through the inclined straight groove 241, thereby causing the sliding plate 231 to move the inclined curved groove 232 to a position where it is no longer in contact with the first pressure-applying block 233.

[0056] Furthermore, the third spring 244 is fixedly installed on the outer surface of the second force-applying column 242, and its other end abuts against the inner wall of the fixing frame 221.

[0057] When using,

[0058] When a sample needs to be removed from a storage tube rack 120: open the sealing cover 130 and press the corresponding first force application column 222. At the same time, the arc block 212 slides along the inner surface of the slide rail 211, while the first spring 223 is compressed. At this time, the arc surface of the arc block 212 squeezes the roller 213, causing the roller 213 to drive the magnetic suction frame 214 to rise along the limit rod 216, thereby lifting the storage tube rack 120 to the outside of the outer box 110, avoiding contact between the user's hand and other storage tube racks 120, thereby preventing the storage tubes in other storage tube racks 120 from being overturned due to improper force by the user.

[0059] During this process: the first pressure block 233 moves synchronously with the first force column 222 and squeezes the sliding plate 231 through the inclined groove 232, thereby causing the sliding plate 231 to slide along the inner wall of the fixed frame 221 and stretch the second spring 235.

[0060] When the first pressure block 233 reaches the inclined end of the inclined groove 232: the reaction force of the second spring 235 drives the sliding plate 231 to reset, thereby causing the right-angle contour of the inclined groove 232 to lock the first pressure block 233 and lock the extended position of the storage tube rack 120.

[0061] When the other first pressure blocks 233 are pressed, the above mechanical movement can be repeated, and the interlocking inclined grooves 232 are separated from the first pressure blocks 233. Then, the reaction force of the first spring 223 drives the first pressure blocks 233 that have been released from the limit to return to the original position. Subsequently, the magnetic suction frame 214 drives the sliding sleeve 215 to fall back into the outer box 110 along the limit rod 216 by gravity.

[0062] After the sample is taken, press the second force column 242 to drive the second pressure block 243 to move synchronously. The second pressure block 243 squeezes the sliding plate 231 through the inclined straight groove 241, causing the sliding plate 231 to slide and drive the inclined groove 232 to disengage from the first pressure block 233. At the same time, the third spring 244 is compressed, and the first force column 222 is pushed back to its original position by the first spring 223. At this time, the arc block 212 retracts and the storage tube rack 120 is driven down along the limit rod 216 into the outer box 110 by the magnetic suction frame 214. Then, the second force column 242 is released and reset by the third spring 244. Finally, the sealing cover 130 is closed and fixed by the locking member 140.

[0063] In summary, by setting up the pop-out mechanism 200, not only can the storage tube rack 120 be lifted to the outside of the outer box 110 and locked without having to put one's hand into the outer box 110 when taking out the storage tube rack 120, but the second force column 242 can also control the storage tube rack 120 to quickly reset, and only allow a single storage tube rack 120 to extend outward, avoiding the storage tube from being overturned due to improper force by the user. This achieves the effect of ensuring the safety and convenience of the sample retrieval process while ensuring the integrity of sample preservation.

[0064] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
