Abstract
Description
Technical Field
[0001] This application relates to the field of food testing technology, and in particular to a sample storage device for grain and oil testing. Background Technology
[0002] Grain and oil testing is a professional technique that uses scientific methods and means to evaluate, detect, and analyze the physical, chemical, and biological properties of grains and oils. The key to grain and oil testing is detecting the content of harmful substances, specific components of the oil, and the levels of harmful substances such as mycotoxins and pesticide residues. Before conducting specific testing, testing personnel first need to collect grain and oil samples from the raw materials. The general sampling procedure is as follows: Testing personnel first select appropriate samplers and sample containers, then use the sampler to obtain oil samples from representative batches, types, and locations of grain and oil at the grain and oil storage site. The extracted oil samples must be quickly sealed in pre-prepared sample containers to prevent oxidation or contamination. Sampling information must also be labeled on the outside of the sample containers to ensure sample traceability. When testing personnel take samples of grains and oils, they often need to use a temporary sample storage box to store the samples in order to safely bring them back to the laboratory. However, the existing sample storage boxes do not provide good fixation for the sample containers. During the movement of the sample storage box, the sample containers are easy to shake and collide with the inner wall of the storage box or with each other, causing the grain and oil samples to leak. Utility Model Content
[0003] This application provides a sample storage device for grain and oil testing, which can effectively fix the sample container when transporting grain and oil samples through a sample storage box, thereby reducing the risk of leakage of grain and oil samples due to container collision and damage.
[0004] The above-mentioned objective of this application is achieved through the following technical solution:
[0005] A sample storage device for grain and oil testing includes an upper box and a lower box that can be freely opened and closed. A bottle holder is fixed to the bottom of the lower box. Multiple embedded grooves are evenly distributed on the bottle holder, and each embedded groove can hold a sample bottle. The shape and area of the cross-section of the embedded groove are equal to the shape and area of the cross-section of the sample bottle.
[0006] The sample storage box has a pressing plate on the inner side of the top plate of the upper box. The pressing plate and the top plate of the upper box are connected by an elastic element. The area of the pressing plate is such that when it is fastened to the lower box of the sample storage box along with the upper box of the sample storage box, it can simultaneously cover the top of all sample bottles on the bottle holder.
[0007] Furthermore, the elastic element is a first spring, and a plurality of first springs are evenly arranged between the pressing plate and the upper body of the sample storage box. One end of the first spring is fixedly connected to the top plate of the upper body of the sample storage box, and the other end of the first spring is in contact with the pressing plate.
[0008] Furthermore, two through-holes are symmetrically opened on opposite side walls along the length of the sample storage box. A locking block is fixedly installed on the pressing plate at a position corresponding to each of the through-holes. The end of the locking block away from the pressing plate is movably inserted into the corresponding through-hole along the horizontal direction. The pressing plate has a number of picking units equal to the number of sample bottles on the side away from the sample storage box. The picking units on the pressing plate are used to remove the sample bottles from the bottle holder.
[0009] Furthermore, the card block is L-shaped, the upper end of the vertical section of the card block is fixedly connected to the pressing plate, the horizontal section of the card block is inserted into the through mounting hole at the end away from its vertical section, the width of the through mounting hole is greater than the thickness of the horizontal section of the card block, and the upper and lower sides of the end of the horizontal section of the card block inserted into the through mounting hole are both arc-shaped slopes.
[0010] Furthermore, each of the vertical and horizontal sections of the card block has a notch at its close end. The notch ends of the vertical and horizontal sections of the card block are slidably connected in the horizontal direction. A second spring is horizontally arranged in the space enclosed by the two notches, and the two ends of the second spring are respectively connected to the vertical and horizontal sections of the card block.
[0011] Furthermore, the picking unit is a suction cup, and the diameter of the suction cup is no greater than the diameter of the sample bottle cap.
[0012] Furthermore, a soft handle is fixedly installed on the middle position of the side of the pressing plate opposite to the suction cup.
[0013] In summary, this application includes at least one of the following beneficial technical effects:
[0014] After sampling the grains and oils, the testing personnel sequentially insert sample bottles containing different grain and oil samples into multiple recessed slots on the bottle holder. Since the cross-sectional shape and area of the recessed slots are equal to those of the sample bottles, the recessed slots provide excellent support and restraint for the lower half of the bottle holder after placement. Furthermore, the spacing between the recessed slots effectively prevents the sample bottles from colliding during movement, thus reducing the risk of sample leakage due to breakage. When the upper and lower boxes of the sample storage box are fastened together, the pressing plate inside the upper box, aided by elastic components, automatically presses against the tops of multiple sample bottles. This further stabilizes the sample bottles during transport, minimizing the risk of shaking. Attached Figure Description

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application are described clearly and completely below. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are also within the scope of protection of this application.
[0023] like Figures 1-5 As shown, this application discloses a sample storage device for grain and oil testing, including an upper box 101 and a lower box 102 that can be freely opened and closed. A bottle holder 2 is fixedly provided at the bottom of the lower box 102 of the sample storage box 1. A plurality of embedded grooves 3 are evenly provided on the bottle holder 2, and a sample bottle 4 can be placed in each embedded groove 3. The shape and area of the cross-section of the embedded groove 3 are equal to the shape and area of the cross-section of the sample bottle 4.
[0024] The upper box 101 of the sample storage box 1 is provided with a pressing plate 5 on the inner side of the top plate. The pressing plate 5 and the top plate of the upper box 101 are connected by an elastic element. The area of the pressing plate 5 is such that when it is fastened to the lower box 102 of the sample storage box 1 along with the upper box 101, it can cover the top of all the sample bottles 4 on the bottle holder 2 at the same time.
[0025] In the above embodiments, the bottle holder 2 fixedly installed at the bottom of the sample storage box 1 can preferably be made of foam or sponge material. This not only reduces manufacturing and replacement costs and facilitates modification, but also provides flexible contact with the sample bottle 4, preventing scratches on the surface of the sample bottle 4 during handling. The shape and area of the embedded groove 3 in the horizontal direction are equal to the shape and area of the sample bottle 4 in the horizontal direction. After the sample bottle 4 containing the grain and oil sample is inserted into the embedded groove 3 of the bottle holder 2, the embedded groove 3 can provide support and limit its position. The embedded grooves 3 on the bottle holder 2 are spaced apart from each other and from the inner wall of the sample storage box 1. This makes it difficult for multiple sample bottles 4 placed on the bottle holder 2 to come into contact with each other or with the inner wall of the sample storage box 1, thereby effectively reducing the risk of breakage and leakage of the grain and oil sample. The embedded groove 3 on the bottle holder 2 of this application mainly serves to limit the horizontal movement of the sample bottle 4. However, when the testing personnel move the sample storage box 1, there is still a risk of the sample bottle 4 swaying vertically. Therefore, this application provides a pressing plate 5 connected by an elastic element on the inner side of the top plate of the upper body 101 of the sample storage box 1. After the testing personnel place the sample bottle 4 and close the upper body 101 of the sample storage box 1, when the pressing plate 5 contacts the sample bottle 4, the sample bottle 4 will continue to move due to the continuous rotation of the upper body 101. The pressing plate 5 will exert a squeezing force, which will drive the pressing plate 5 to move towards the top plate of the upper box 101 of the sample storage box 1. During this process, the elastic element will be compressed to generate elastic force. After the upper box 101 and lower box 102 of the sample storage box 1 are fully engaged, the elastic element will use its elastic force to react on the pressing plate 5, thereby causing the pressing plate 5 to exert a downward squeezing force on the sample bottle 4. This force, in conjunction with the bottle holder 2, can move the sample bottle 4 vertically during the movement process, which can further improve the stability of the sample bottle 4 during the transfer process.
[0026] Furthermore, such as Figure 1 , Figure 2 and Figure 5 As shown, the elastic element is a first spring 6. Multiple first springs 6 are evenly arranged between the pressing plate 5 and the upper box 101 of the sample storage box 1. One end of the first spring 6 is fixedly connected to the top plate of the upper box 101 of the sample storage box 1, and the other end of the first spring 6 is in contact with the pressing plate 5.
[0027] In the above embodiments, multiple first springs 6 are provided between the pressing plate 5 and the top plate of the upper box 101 of the sample storage box 1. This ensures that after the upper box 101 and the lower box 102 of the sample storage box 1 are fastened together, the top plate of the upper box 101 can apply a squeezing force to the pressing plate 5 evenly through multiple springs, so that the fixing effect of multiple sample bottles 4 is equally stable and firm.
[0028] Furthermore, such as Figures 2-5 As shown, two through mounting holes 7 are symmetrically opened on opposite side walls of the sample storage box 101 along the length direction. A locking block 8 is fixedly installed on the pressing plate 5 at the position corresponding to these through mounting holes 7. The end of the locking block 8 away from the pressing plate 5 is movably inserted into the through mounting hole 7 at the corresponding position in the horizontal direction. The pressing plate 5 is provided with a number of picking units equal to the number of sample bottles 4 on the side away from the sample storage box 101. The picking units on the pressing plate 5 are used to remove the sample bottles 4 from the bottle holder 2.
[0029] In the above embodiments, after the testing personnel transfer multiple samples to the laboratory through the sample storage box 1, they need to open the upper box 101 of the sample storage box 1 and take out the sample bottles 4 one by one from the bottle holder 2 in the lower box 102. This process is quite cumbersome. In this application, a number of picking units equal to the number of sample bottles 4 are provided on the side of the pressing plate 5 away from the top plate of the upper box 101. When the upper box 101 and the lower box 102 are in the snap-fit state, the positions of the multiple picking units on the pressing plate 5 correspond one-to-one with the positions of the multiple sample bottles 4 in the lower box 102. This ensures that the multiple picking units can accurately contact and act on the multiple sample bottles 4. Furthermore, the two ends of the pressing plate 5 in this application are respectively movably inserted into the through mounting holes 7 on the upper body 101 of the sample storage box 1 via locking blocks 8. When the upper body 101 of the sample storage box 1 is opened and closed, the locking blocks 8 guide the pressing plate 5 through the through mounting holes 7, allowing it to move smoothly along its thickness direction within the sample storage box 1. In addition, the pressing plate 5 and the first spring 6 are only in contact and have no actual connection. Thus, when the testing personnel need to remove the sample bottles 4 from the sample storage box 1, they can remove the pressing plate 5 from the upper body 101 of the sample storage box 1, and use the pressing plate 5 and its multiple pickup units to quickly remove all the sample bottles 4 from the sample storage box 1 together, thereby simplifying the process of removing the sample bottles 4 from the sample storage box 1 and improving work efficiency.
[0030] Furthermore, such as Figure 2 and Figure 3 As shown, the card block 8 is L-shaped. The upper end of the vertical section 81 of the card block 8 is fixedly connected to the pressing plate 5. The horizontal section 82 of the card block 8 is inserted into the through mounting hole 7 at the end away from its vertical section 81. The width of the through mounting hole 7 is greater than the thickness of the horizontal section 82 of the card block 8. The upper and lower sides of the end of the horizontal section 82 of the card block 8 inserted into the through mounting hole 7 are both arc-shaped inclined surfaces 83.
[0031] In the above embodiments, the thickness of the horizontal segment 82 of the locking block 8 is less than the width of the through mounting hole 7. This provides effective movement space for the locking block 8, ensuring that when the upper box 101 of the sample storage box 1 is fastened to its lower box 102, the pressing plate 5 can move smoothly within the upper box 101 of the sample storage box 1 when subjected to the pressure of the sample bottle 4, thereby compressing the first spring 6 and causing the first spring 6 to generate an elastic force that restricts the vertical displacement of the sample bottle 4. In addition, the upper and lower sides of the horizontal segment 82 of the locking block 8 inserted into the through mounting hole 7 are both arc-shaped inclined surfaces 83, and the concave sides of the two arc-shaped inclined surfaces 83 face towards their middle. Thus, when the pressing plate 5 moves away from or towards the top plate of the upper box 101, the arc-shaped inclined surfaces 83 on the corresponding sides of the horizontal segment 82 of the locking block 8 help to smoothly disengage from or insert into the through mounting hole 7.
[0032] Furthermore, such as Figure 2 and Figure 3 As shown, a notch 84 is provided at the close ends of the vertical section 81 and the horizontal section 82 of the locking block 8. The notch 84 ends of the vertical section 81 and the horizontal section 82 of the locking block 8 are slidably connected in the horizontal direction. A second spring 85 is horizontally provided in the space enclosed by the two notches 84. The two ends of the second spring 85 are connected to the vertical section 81 and the horizontal section 82 of the locking block 8, respectively.
[0033] In the above embodiments, the notches 84 of the vertical segment 81 and the horizontal segment 82 of the locking block 8 provide space for the installation of the second spring 85. The axis of the second spring 85 is parallel to the horizontal segment 82 of the locking block 8, and the notches 84 of the vertical segment 81 and the horizontal segment 82 of the locking block 8 are slidably connected in the horizontal direction (e.g., Figure 3As shown, a wedge-shaped plug is provided on one side of the notch 84 end of the vertical segment 81 of the locking block 8, and a matching wedge-shaped groove is provided on one side of the notch 84 end of the horizontal segment 82. A wedge-shaped groove is provided on the other side of the notch 84 end of the vertical segment 8, and a matching wedge-shaped plug is provided on the other side of the notch 84 end of the horizontal segment 82. The wedge-shaped groove ensures that the wedge-shaped plug can slide freely along its length direction, while the wedge-shaped plug will not detach along the length direction of the vertical segment, thereby achieving the effect of sliding connection between the vertical segment 81 and the horizontal segment 82 of the locking block 8. When the pressing plate 5 is removed from the upper box 101 of the sample storage box 1, the lower edge of the through mounting hole 7 will exert a squeezing force on the arc-shaped inclined surface 83 on the lower side of the horizontal section 82 of the locking block 8. The horizontal component of this force will push the horizontal section 82 of the locking block 8 to slide towards the vertical section 81, while squeezing the second spring 85. When the horizontal section 82 of the locking block 8 is removed from the through mounting hole 7, the testing personnel can easily remove the pressing plate 5 from the upper box 101 of the sample storage box 1. When the pressing plate 5 needs to be placed back into the upper box 101 of the sample storage box 1, the inspector presses the pressing plate 5 into the upper box 101. The locking block 8 on the side of the pressing plate 5 will apply this force to the side wall of the upper box 101 that is in contact with it. The side wall of the upper box 101 that is in contact with it will also generate a reaction force on the locking block 8. When this force acts on the arc-shaped inclined surface 83 of the horizontal section 82 of the locking block 8, it will generate a horizontal component force. This force will squeeze the horizontal section 82 of the locking block 8, causing it to move towards the vertical section 81 and compress the second spring 85. After the horizontal section 82 of the locking block 8 avoids the side wall of the upper box 101 that is interfering with it, the pressing plate 5 will continue to slide along the thickness direction of the upper box 101. When the horizontal section 82 reaches the through mounting hole 7 on the side wall of the upper box 101, the elastic force of the second spring 85 will cause the horizontal section 82 of the locking block 8 to reset, so that the horizontal section 82 of the locking block 8 is reinserted into the through mounting hole 7 and forms a stable connection with the first spring 6. By setting the card block 8 in the above manner, the risk of deformation due to force at the joint between the horizontal section 82 and the vertical section 81 of the card block 8 when the card block 8 is moved in and out of the through mounting hole 7 can be reduced.
[0034] Furthermore, such as Figure 2 As shown, the pickup unit is suction cup 9, and the diameter of suction cup 9 is no greater than the diameter of the cap of sample bottle 4.
[0035] In the above embodiments, the picking unit of this application is a suction cup 9 with a diameter no larger than the diameter of the sample bottle 4 cap. Thus, when the upper box 101 and lower box 102 of the sample storage box 1 are fastened together, the multiple suction cups 9 on the pressing plate 5 can be firmly adsorbed onto the caps of the multiple sample bottles 4 under the action of the first spring 6. During the transfer process, the suction cups 9 not only cooperate with the pressing plate 5 and the first spring 6 to effectively limit the upper end of the sample bottle 4, but also, the flexible material of the suction cups 9, located between the sample bottle 4 and the pressing plate 5, allows for flexible contact with the sample bottle 4. While ensuring the fixation effect on the sample bottle 4, it also provides shock absorption and reduces wear. Figure 4 and Figure 5 After the testing personnel transfer the sample storage box 1 to the laboratory, if they need to retrieve the samples, they will usually first open the upper box 101 of the sample storage box 1. Since the pressing plate 5 inside the upper box 101 is connected to multiple sample bottles 4 by suction cups 9, and the inner wall of the embedded groove 3 in the bottle holder 2 is in friction with the outer wall of the sample bottle 4, the pressing plate 5 will be subjected to a significant dragging force. This force will drive the horizontal section 82 of the locking block 8 on the side of the pressing plate 5 to disengage from the through mounting hole 7, so that the pressing plate 5 stays on top of the sample bottle 4 as much as possible. In this way, after the testing personnel open the upper box 101 of the sample storage box 1, the suction between the suction cup 9 on the pressing plate 5 and the sample bottle 4 can keep the pressing plate 5 automatically on top of multiple sample bottles 4. The testing personnel only need to lift the pressing plate 5 vertically to remove all the sample bottles 4 from the sample storage box 1 at the same time, which greatly simplifies the operation steps of removing the sample bottles 4 from the sample storage box 1 and improves efficiency.
[0036] Furthermore, such as Figure 5 As shown, a soft handle 10 is fixedly installed on the middle position of the side opposite to the suction cup 9 on the pressing plate 5.
[0037] In the above embodiments, the soft handle 10 provided on the pressing plate 5 can be made of canvas or artificial leather. This allows the soft handle 10 to be folded up when the pressing plate 5 is placed inside the sample storage box 1, reducing the space required inside the upper box 101 of the sample storage box 1. When transferring sample vials 4, the testing personnel can quickly apply force through the soft handle 10 and press the pressing plate 5 to simultaneously remove multiple sample vials 4 from the sample storage box 1.
[0038] The implementation principle of this embodiment is as follows: After the testing personnel complete the sampling of grains and oils, they insert the sample bottles 4 containing different grain and oil samples into the multiple embedded grooves 3 of the bottle holder 2 in sequence. When the upper box 101 and the lower box 102 of the sample storage box 1 are fastened together, the pressure plate inside the upper box 101 will automatically press the top of the bottle caps of the multiple sample bottles 4 with the action of the first spring 6. In this way, the risk of the sample bottles 4 shaking during the transportation process will be significantly reduced, and the risk of grain and oil sample leakage due to bumps will be effectively avoided. After the testing personnel bring the grain and oil samples to the laboratory through the sample storage box 1, when it is necessary to take out the sample bottles 4 containing the grain and oil samples from the box, the testing personnel open the upper box 101 of the sample storage box 1. The pressing plate 5 inside the upper box 101 will remain above the sample bottles 4 under the action of the suction cup 9. Then, the testing personnel hold the soft handle 10 and lift the pressing plate 5 upwards, so that multiple sample bottles 4 can be taken out from the sample storage box 1 at the same time. This can effectively improve the efficiency of taking out the sample bottles 4.
[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them.
