Description

Technical Field

[0001] This utility model relates to the field of food testing technology, and in particular to a food testing sample placement rack. Background Technology

[0002] In the field of food testing, the standardized storage and efficient management of samples are key to ensuring the accuracy of test results and the smoothness of the workflow. With the continuous increase in the volume of food testing business, the types of test samples are becoming more and more diverse, and the corresponding storage container specifications also vary significantly. At the same time, in order to ensure the stability of the sample properties before testing, most food test samples need to be stored in a low-temperature environment. This requires that the sample rack not only have the function of classification and storage, but also need to be adapted to the low-temperature storage scenario and meet the stable placement requirements of containers of various sizes.

[0003] Existing food testing sample racks generally consist of a basic frame and multiple layers of placement plates. The sample containers are positioned by fixing holes in the placement plates, and they can be used with external refrigeration equipment for low-temperature storage. The overall structure adopts a traditional layered parallel design, with each layer of placement plates having the same height. This design aims to provide basic classified storage space for food testing samples, thus solving the problem of random sample stacking to some extent.

[0004] However, in actual use, the labels of the sample containers on each layer are easily obscured by the upper plate or the container in front due to the layered parallel layout of the aforementioned rack. Staff need to repeatedly adjust their viewing angle or move the sample in front to identify the label information, which greatly reduces the efficiency of sample identification and retrieval. At the same time, the size of the fixing holes on the plate is mostly uniform and cannot be adapted to sample containers of different diameters. If they are forcibly placed, the containers may shake and tilt, or even pose a risk of sample leakage. Therefore, a food testing sample rack is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a food testing sample rack, which aims to solve the problems in the prior art where the labels of the samples placed inside are easily obscured, making identification and retrieval difficult, and the fixed size of the fixing holes on the placement plate leads to poor adaptability.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a food testing sample placement rack, comprising an outer shell, a sealing door hinged to the front side of the outer shell, a cooler fixedly connected to the bottom surface of the inner shell, and several placement box groups fixedly connected in a vertical linear array inside the outer shell, each placement box group being composed of several placement boxes fixedly connected to each other in a stepped manner, a plug-in box being inserted into the inside of each placement box, a slot being provided on the upper surface of the plug-in box, a sponge tube being fixedly connected inside the slot, a limiting component being provided at the bottom of the placement box for limiting the plug-in box, and side plates fixedly connected to the left and right surfaces of the plug-in box;

[0007] The limiting component includes a bolt and a screw hole. The bolt is located at the bottom of the placement box, and the screw hole is opened on the bottom surface of the insertion box. The top of the bolt passes through the placement box and is threaded into the screw hole.

[0008] As a further description of the above technical solution:

[0009] The upper surfaces of the several placement boxes that make up the placement box group rise sequentially from front to back.

[0010] As a further description of the above technical solution:

[0011] A gap is left between the bottom surface of the side panel and the upper surface of the corresponding box.

[0012] As a further description of the above technical solution:

[0013] A through groove is provided on the upper surface of the placement box assembly.

[0014] As a further description of the above technical solution:

[0015] All of the aforementioned placement boxes have the same length and are fixedly attached to the inner wall of the outer shell.

[0016] As a further description of the above technical solution:

[0017] A U-shaped limiting frame is fixedly connected to the bottom surface of the box, and a limiting plate is fixedly connected to the outside of the bolt.

[0018] As a further description of the above technical solution:

[0019] The top of the bolt passes through the U-shaped limiting frame, and the limiting plate is located inside the U-shaped limiting frame.

[0020] As a further description of the above technical solution:

[0021] The bolt head has anti-slip grooves on the outer side.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, the combination of the placement box group, the insertion box, the slot and the sponge tube allows the samples to be placed in a staggered manner, so that the labels of each layer are fully exposed, improving the identification and retrieval efficiency. At the same time, the diameter of the slot increases from front to back and is equipped with a sponge tube, which can be adapted to multiple sizes of containers, and provides vibration reduction and anti-slip. The setting limit component can quickly limit the insertion box, preventing the entire layer from being lifted when picking up a single item, and quickly unlocking when the entire layer needs to be picked up or put down. The operation mode is clear and efficient.

[0024] 2. In this utility model, the through slot can promote the exchange of airflow between the upper and lower parts, and achieve more uniform and faster cooling in conjunction with the refrigeration. The U-shaped limit frame and limit plate can limit the bolts, preventing them from falling off or being lost due to improper operation or vibration, and ensuring the integrity of the equipment for long-term use.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figures 1-3 This utility model provides an embodiment of a food testing sample rack, comprising an outer shell 1, with a sealing door 2 hinged to the front side of the outer shell 1. The sealing door 2 can seal and shield the interior of the outer shell 1. A door lock is provided on the outside of the sealing door 2 to lock and limit the sealing door 2 after it is closed. A cooler 3 is fixedly connected to the bottom surface of the interior of the outer shell 1. The cooler 3 can regulate the temperature of the interior of the outer shell 1. The air outlet of the cooler 3 is located on its upper surface, and the air inlet is located on the right side. An air inlet groove corresponding to the air inlet of the cooler 3 is opened on the right side surface of the outer shell 1. The air inlet groove adopts a grid-like design. Air enters from the air inlet, is cooled by the cooler 3, and is blown out from the air outlet, forming a circulating air channel inside the outer shell 1 to ensure that the cold air can flow evenly through each placement box 41, thereby achieving effective cooling of the sample. A temperature sensor can be installed inside the outer shell 1 for real-time monitoring of the internal temperature. The temperature sensor is connected to the control circuit of the cooler 3. The above structures are all existing technologies in the field and will not be described in detail here.

[0035] Inside the outer shell 1, several placement box groups 4 are fixedly connected in a vertical linear array. Each placement box group 4 is composed of several placement box bodies 41 connected to each other in a stepped manner. The lengths of the placement box bodies 41 are all the same (length refers to the distance in the left-right direction of the placement box body 41), and they are all fixedly attached to the inner wall of the outer shell 1. The upper surfaces of the placement box bodies 41 forming the placement box group 4 rise sequentially from front to back, and the widths of the placement box bodies 41 increase sequentially from front to back (width refers to the distance in the front-back direction of the placement box body 41). Insertion boxes 5 are inserted into the placement box bodies 41 for stable placement. The upper surface of the insertion box 5 is provided with slots 6. There are several slots 6 arranged in a left-right straight array on the insertion box 5 to facilitate the placement and positioning of multiple sample containers. A sponge tube 7 is fixedly connected to the inside of the slot 6 by adhesive. The sponge material can be selected with a Shore hardness of 20-30HA to ensure that it can provide a certain cushioning protection for the sample container and provide suitable friction. In terms of interference fit, the inner diameter of the sponge tube 7 is 0.5-1.5mm smaller than the outer diameter of the inserted sample container on one side to achieve interference fit and ensure the stability of the sample container in the slot 6.

[0036] The diameter of the slots 6 on the plug-in boxes 5 gradually increases from front to back to accommodate sample placement containers of different sizes. The sponge tube 7 can prevent hard contact between the sample placement container and the plug-in box 5. At the same time, the sponge tube 7 and the inserted sample placement container are interference fit. The sample placement container will squeeze the inner wall of the sponge tube 7, thereby increasing the friction with the outside of the sample placement container and improving the placement stability of the sample placement container. The staggered placement boxes 41 can use the height difference to make the labels on the sample placement containers inside each plug-in box 5 fully exposed, making it convenient for staff to identify and take them. At the same time, the outer sample can be taken directly from the front, and the inner sample is in a higher position, so the hands do not need to cross the outer sample, making the storage and retrieval operation smoother.

[0037] Reference Figures 4-6 Side plates 9 are fixedly connected to the left and right surfaces of the plug-in box 5. The side plates 9 can provide a pull-out force point for the plug-in box 5, making it convenient for staff to pick up the placement box 41. A gap is left between the bottom surface of the side plate 9 and the corresponding upper surface of the placement box 41 to prevent the side plate 9 from sticking to the placement box 41 and affecting the picking up of the plug-in box 5. A limit component 8 is provided at the bottom of the placement box 41. The limit component 8 is used to limit the plug-in box 5. The limit component 8 includes a bolt 81 and a screw hole 82. The bolt 81 is located at the bottom of the placement box 41. The outer side of the head of the bolt 81 is provided with anti-slip texture to increase the friction between the bolt and the staff's hand and reduce slippage. The screw hole 82 is opened on the bottom surface of the plug-in box 5. The top of the bolt 81 penetrates the placement box 41 and is threadedly connected to the inside of the screw hole 82. The bolt 81 is threadedly connected to the placement box 41. When the bolt 81 is turned, it can move vertically relative to the placement box 41.

[0038] After inserting the connector box 5 into the placement box 41, the bolt 81 can be turned upwards into the screw hole 82 to quickly limit the connector box 5. This prevents the connector box 5 from moving upwards synchronously due to the friction between the sample placement container and the sponge tube 7 when a single sample placement container needs to be removed, thus reducing the efficiency of removing a single sample placement container. If it is necessary to remove the entire connector box 5 to remove multiple sample placement containers at once, the bolt 81 can be turned downwards to quickly release the limit on the connector box 5, and then the entire connector box 5 can be removed. The operation is simple.

[0039] Reference Figures 4-6A through groove 10 is provided on the upper surface of the placement box assembly 4, allowing air to quickly exchange between the upper and lower sides of the placement box assembly 4. This enables the interior of the outer shell 1 to cool down quickly after the cooler 3 is started. A U-shaped limiting frame 11 is fixedly connected to the bottom surface of the placement box 41. A limiting plate 12 is fixedly connected to the outside of the bolt 81. The top of the bolt 81 passes through the U-shaped limiting frame 11, and the limiting plate 12 is located inside the U-shaped limiting frame 11. The U-shaped limiting frame 11 can limit the limiting plate 12, preventing the limiting plate 12 from detaching from the U-shaped limiting frame 11 and thus avoiding the bolt 81 from detaching from the U-shaped limiting frame 11 and being lost.

[0040] Working principle: The staff opens the hinged sealed door 2 on the front of the outer shell 1 through the door lock on the outside of the sealed door 2. At this time, the placement box assembly 4 inside the outer shell 1 is fully exposed. If the sample needs to be stored at low temperature, the cooler 3 fixed on the bottom of the inner shell is activated. The cooler 3 begins to cool and regulate the internal space of the outer shell 1. Then, according to the specifications of the sample placement container, the insertion box 5 with the corresponding slot 6 diameter is selected. Since the diameter of the slot 6 on the insertion box 5 gradually increases from front to back, it can match containers of different sizes. The sample placement container is inserted into the slot 6 of the insertion box 5. The sponge tube 7 inside the slot 6 is interference-fitted with the container. The container is initially fixed by the compression of the sponge tube 7. Then, the insertion box 5 containing the sample is inserted into the placement box body 41 of the placement box assembly 4. The placement box assembly 4 is composed of several placement box bodies 41 fixed in a stepped manner. The upper surface of the placement box body 41 rises and the width increases from front to back. When inserting, it can be directly guided along the inner wall of the placement box body 41 to complete the docking.

[0041] After the plug box 5 is in place, tighten the bolt 81 of the bottom limiting component 8 of the placement box 41. The top of the bolt 81 passes through the placement box 41 and is threaded into the screw hole 82 on the bottom surface of the plug box 5 until the bolt 81 is fully locked, thereby fixing the plug box 5 to the placement box 41 and preventing the plug box 5 from shifting when the sample is taken out separately later. Finally, close the sealing door 2 and lock it with the door lock to complete the sample storage.

[0042] When samples need to be retrieved, if only one sample needs to be retrieved, after opening the sealing door 2, the required sample can be directly pulled out from the target slot 6 and placed into the container. Because the bottom bolt 81 has fixed the plug box 5, even if there is friction between the container and the sponge tube 7 during retrieval, the plug box 5 will not move upwards synchronously, allowing for quick retrieval of a single sample. After retrieval, no additional operation is required; simply close the sealing door 2. If the entire sample in the plug box 5 needs to be retrieved at once, first unscrew the bolt 81 downwards so that the top of the bolt 81 disengages from the screw hole 82 on the bottom surface of the plug box 5. Release the limit on the plug box 5, and then pull the plug box 5 out of the placement box 41 through the side plates 9 on the left and right sides of the plug box 5 to complete the batch sample taking. If a new plug box 5 needs to be stored after taking it, the above steps can be repeated. During this process, the limit plate 12 is fixedly connected to the outside of the bolt 81, and the U-shaped limit frame 11 fixed on the bottom surface of the placement box 41 forms a wrapping limit on the limit plate 12. Even if the bolt 81 is completely loosened, the limit plate 12 cannot be removed from the U-shaped limit frame 11, which can effectively prevent the bolt 81 from falling off and being lost, and reduce equipment maintenance costs.

[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
