Technical Field
[0001] This utility model relates to the field of food inspection technology, and in particular to a sample storage and sorting rack for import and export food inspection. Background Technology
[0002] With increasingly frequent global food trade, import and export food inspection has become a crucial line of defense for safeguarding public health and maintaining market order. Every day, a massive and diverse array of food samples floods into laboratories, covering fresh fruits and vegetables, meat products, processed foods, and more. Some require refrigeration, while others have stringent requirements for protection from light and moisture. These samples undergo lengthy transportation, multiple transfers, and prolonged storage; any slight oversight during this process can damage the samples, affecting the accuracy of test results and ultimately interfering with food safety assessments. Therefore, the development of efficient and reliable storage and organization racks is urgently needed.
[0003] Most existing conventional sample storage racks use a combination of a rigid frame and fixed-spaced shelves. The frame is mostly made of metal to ensure basic structural strength, while the shelves are often made of wood or plastic, making them economical. Placing sample boxes mainly relies on manual arrangement, with samples roughly categorized and stacked based on experience. Some large warehouses also use forklifts for easy bulk handling of entire stacks of samples. During transportation, ropes and ordinary straps are used to simply secure the sample stacks, preventing large-scale scattering, making them suitable for short-distance, stable road transport scenarios.
[0004] When food sample storage cabinets are in dynamic environments, such as when vehicles accelerate, brake, or turn during transportation, or when large instruments in the laboratory vibrate continuously, the sample boxes are prone to danger. Due to the lack of reliable clamping and stabilizing devices, the sample boxes begin to shake violently. If the food samples inside leak out, they will contaminate the surrounding samples and interfere with the subsequent testing process, affecting the timeliness and accuracy of import and export food inspection. To address these issues, a metal longitudinal slitting machine is proposed. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a sample storage and sorting rack for import and export food inspection, which aims to improve the problem that sample boxes in the prior art are prone to shaking due to external forces.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A sample storage and organization rack for import and export food inspection includes a cabinet body. Casters are fixedly connected to the bottom of the cabinet body. A cabinet door is rotatably connected to the side wall of the cabinet body, and a handle is fixedly connected to the side wall of the cabinet door. An operation panel is fixedly connected to one side of the cabinet body. A camera is fixedly connected inside the cabinet body. A placement board is provided inside the cabinet body. A sample box is placed on top of the placement board. A support plate is fixedly connected inside the placement board. An electric push rod is fixedly connected inside the support plate. A fixed base is fixedly connected to the output end of the electric push rod. A sliding block is fixedly connected to the top of the fixed base. A platform is fixedly connected to the top of the support plate. A sliding groove is formed inside the platform. The outer wall of the sliding block is slidably connected to the sliding groove. A clamp is fixedly connected to the top of the sliding block.
[0008] As a further description of the above technical solution:
[0009] A support frame is fixedly connected inside the cabinet, and a push column is fixedly connected to the bottom of the placement board.
[0010] As a further description of the above technical solution:
[0011] A sliding conical block is fixedly connected to the bottom of the push column, and a support plate is fixedly connected to the top of the support frame.
[0012] As a further description of the above technical solution:
[0013] A positioning post is fixedly connected to the top of the pallet, and the inner wall of the sliding conical block is slidably connected to the outer wall of the positioning post.
[0014] As a further description of the above technical solution:
[0015] A fixing plate is fixedly connected to the top of the tray, and a locking post is fixedly connected inside the fixing plate.
[0016] As a further description of the above technical solution:
[0017] The inner wall of the locking post is movably connected to a sliding post, the outer wall of the sliding post is fitted with a spring, and one end of the sliding post is fixedly connected to a movable clamping plate.
[0018] As a further description of the above technical solution:
[0019] One end of the spring is fixedly connected to the side wall of the fixed plate, and the other end of the spring is fixedly connected to the side wall of the movable clamping plate.
[0020] As a further description of the above technical solution:
[0021] The movable clamp is slidably connected to a fixed column on its side wall, and the bottom of the fixed column is slidably connected to the top of the support plate.
[0022] This utility model has the following beneficial effects:
[0023] 1. In this utility model, the electric push rod is activated to move the fixed base, which in turn moves the fixed base on the other side. Then, the sliding blocks on both sides slide in the slide groove, so that the slide groove slides on the platform, thereby moving the clamp towards the middle, so that the clamps on both sides hold the sample box, avoiding leakage caused by shaking of the sample box and contamination of other samples and the environment.
[0024] 2. In this utility model, pressing the placement plate drives the pushing column to move, and the pushing column drives the sliding conical block to move down. Since the contact surface between the moving clamp and the sliding conical block is an inclined surface, the positioning column limits the sliding conical block, thereby pushing the moving clamp to move outward, which in turn drives the spring on the outer wall of the sliding column to compress, thereby realizing the disassembly of the placement plate, thus making full use of the vertical space and increasing the storage capacity of the sample retention cabinet.

[0032] 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.
[0033] Reference Figure 1 - Figure 3This utility model provides an embodiment of a sample storage and organization rack for import and export food inspection, comprising a cabinet body 1. The surface of the cabinet body 1 is treated with electrostatic spraying, uniformly covered with a layer of wear-resistant, corrosion-resistant, and easy-to-clean environmentally friendly coating. The coating has a soft and long-lasting color, is both aesthetically pleasing and effectively prevents the cabinet body 1 from rusting or getting stained, thus extending its service life. Universal wheels 2 are fixedly connected to the bottom of the cabinet body 1. The bearings of the wheels adopt a ball bearing structure and undergo special sealing treatment, effectively preventing dust and water damage, allowing for flexible and smooth rotation, improving ease of use, and reducing the labor intensity of manual handling. A cabinet door 3 is rotatably connected to the side wall of the cabinet body 1. The main body of the cabinet door 3 is made of transparent acrylic sheet. Acrylic material has high transparency, appearing as clear as glass, allowing laboratory personnel to operate the cabinet without opening it. Door 3 provides a clear view of the approximate storage status of the internal samples, allowing for quick location of target samples and saving time. A handle 4 is fixedly connected to the side wall of cabinet door 3. The handle 4 is designed with ergonomic principles in mind, using aluminum alloy with a finely textured frosted surface for a cool and comfortable touch. An operation panel 5 is fixedly connected to one side of cabinet 1. The surface of the operation panel 5 is covered with a 5mm thick high-strength tempered glass layer. This glass undergoes chemical tempering treatment, effectively resisting scratches and impacts during daily use, ensuring the screen display area remains clear and undamaged. A camera 6 is fixedly connected inside cabinet 1. The camera 6's housing is made of aviation-grade aluminum alloy, precision die-cast and CNC machined, resulting in a compact structure, good sealing, and "three-proof" characteristics: waterproof, dustproof, and moisture-proof. The internal structure includes a placement plate 8, which is injection molded from food-grade high-strength engineering plastic. This plastic material is non-toxic and odorless, meeting stringent international food contact safety standards and will not contaminate the samples. A sample box 9 is mounted on top of the placement plate 8, with a finely frosted surface and a moderate coefficient of friction. This prevents accidental slippage of the sample box 9 and facilitates its placement and retrieval. A support plate 11 is fixedly connected inside the placement plate 8. The support plate 11 is welded from stainless steel square tubing, and the wall thickness of the tubing is precisely calculated to ensure sufficient rigidity, providing stable support for subsequent transmission components such as the electric push rod 10. The electric push rod 10 is fixedly connected inside the support plate 11. The electric push rod 10 serves as the key power source for driving the clamp 16. Employing an advanced ball screw transmission structure, the motor smoothly and seamlessly engages with the matching nut, resulting in high transmission efficiency and precise conversion of motor rotational motion into linear thrust. The output end of the electric push rod 10 is fixedly connected to a mounting base 12, which is made of die-cast aluminum alloy. Aluminum alloy offers excellent heat dissipation, rapidly dissipating the heat generated by the generator and preventing overheating from affecting component performance. A sliding block 15 is fixedly connected to the top of the mounting base 12. The sliding block 15 is made of self-lubricating nylon, with a smooth and delicate surface, good wear resistance, and inherent lubrication properties. It maintains a low coefficient of friction during long-term sliding without the need for additional lubricant, ensuring smooth engagement with the slide groove 14. A platform 13, made of thick phenolic resin board, is fixedly connected to the top of the support plate 11.This type of board possesses excellent insulation, moisture resistance, high temperature resistance, and mechanical strength properties, enabling it to adapt to the complex and variable temperature and humidity environment of a laboratory. The platform 13 has an internal sliding groove 14, with ultra-high molecular weight polyethylene (UHMWPE) guide rails embedded in its inner wall. These guide rails have an extremely low coefficient of friction, superior wear resistance, and self-lubricating properties, ensuring a high degree of fit with the outer wall of the sliding block 15. The outer wall of the sliding block 15 is slidably connected to the inside of the sliding groove 14. A clamp 16 is fixedly connected to the top of the sliding block 15. The part of the clamp 16 that contacts the sample box 9 is covered with a soft silicone pad. The silicone pad is made of food-grade silicone, which is soft, delicate, and moderately elastic. It gently and securely clamps the sample box 9, preventing damage to the sample box 9 and its internal samples due to excessive clamping force, and effectively preventing scratches on the surface of the sample box 9, ensuring sample safety.
[0034] Specifically, when cabinet 1 is in operation, the sample box 9 may shake due to factors such as the operation of internal equipment and vibration of the surrounding environment. If the shaking amplitude is too large, the sample box 9 is prone to collision or even falling, which may damage the sample, distort the test data, and seriously hinder the progress of subsequent testing work. At this time, the electric push rod 10 is activated to push the fixed seat 12 connected to it to move smoothly. At the same time, the electric push rod 10 on one side operates synchronously, driving the corresponding fixed seat 12 to move in coordination. Then, the sliding block 15 on the fixed seat 12 slides smoothly in the slide groove 14, pulling the slide groove 14 to move above the platform 13, thereby causing the clamps on both sides to close in the middle and clamp the sample box 9. After sampling is completed, the electric push rods 10 on both sides move in opposite directions, the sliding block 15 and the clamps 16 return to their positions in an orderly manner, quickly release the clamp, resist external impact, maintain the integrity of the sample, and ensure the reliability of subsequent test data.
[0035] Reference Figure 1 , Figure 2 and Figure 4The cabinet 1 is internally connected to a support frame 7. The uprights of the support frame 7 are designed as robust rectangular hollow steel pipes, ensuring excellent vertical load-bearing capacity while cleverly reducing weight. The bottom of the placement plate 8 is fixedly connected to a pushing column 19, which is made of aviation-grade aluminum alloy and integrally molded using precision die-casting technology. After molding, the surface undergoes hard anodizing treatment, significantly increasing its hardness. A sliding conical block 20 is fixedly connected to the bottom of the pushing column 19. The sliding conical block 20 is tapered, wider at the top and narrower at the bottom, with the larger end fitting snugly against the pushing column 19 to ensure structural stability and durability. The top of the support frame 7 is fixedly connected to a tray 17, which has a moderate thickness and... Uniform, formed by high-precision laser cutting, with rounded, burr-free edges, possessing both toughness and strength, and a finely mirror-polished surface, it is both aesthetically pleasing and effectively prevents sample residue and bacterial growth, facilitating cleaning and maintenance. A positioning post 21 is fixedly connected to the top of the tray 17. The positioning post 21 is a solid stainless steel cylindrical structure, its material perfectly matching that of the tray 17. The inner wall of the sliding conical block 20 is slidably connected to the outer wall of the positioning post 21. A fixing plate 18 is fixedly connected to the top of the tray 17. The fixing plate 18 is injection molded from high-performance engineering plastic, with optimized mold design, lightweight yet extremely rigid, and is embedded with a fixing post 26. The inner wall of the fixing post 26 is dynamically connected to... The sliding column 25 is made of 40Cr alloy steel with a surface nitriding treatment. The nitriding layer has an appropriate depth, effectively improving wear resistance and rust prevention, ensuring long-term stable operation. The shaft end is finely rounded to avoid scratching other parts. A spring 23 is sleeved on the outer wall of the sliding column 25. The spring 23 is made of high-quality piano wire and undergoes a strict heat treatment process, possessing a stable and precise elastic coefficient, exhibiting high reliability during compression and relaxation. A movable clamping plate 22 is fixedly connected to one end of the sliding column 25. The main body of the movable clamping plate 22 is made of aluminum alloy, and custom-made wear-resistant rubber strips are inlaid on both sides. The surface of the rubber strips has a slightly serrated texture. This design avoids scratching the contact parts and significantly enhances friction, ensuring stable and efficient clamping. One end of the spring 23 is fixedly connected to the side wall of the fixed plate 18, and the other end of the spring 23 is fixedly connected to the side wall of the movable clamping plate 22. The side wall of the movable clamping plate 22 is slidably connected to the fixed column 24. The bottom of the fixed column 24 is made of a cylindrical bottom surface that has been ground with high precision. It is smoothly slidably connected to the top of the tray 17, ensuring the stability and accuracy of the overall structure during dynamic adjustment. The coordinated operation realizes the flexible disassembly and stable installation of the placement plate 8, improving the practicality and adaptability of the sample storage and sorting rack, and meeting the complex and ever-changing sample management needs of import and export food inspection.
[0036] Specifically, when faced with the task of placing the placement plate 8, pressing the placement plate 8 causes the pushing column 19 to move, which in turn causes the sliding cone block 20 connected to the bottom to move synchronously. At this time, the sliding cone block 20 slides on the outer wall of the positioning column 21. Due to the inclined contact surface between the moving clamp 22 and the sliding cone block 20, the movement of the sliding cone block 20 is converted into a lateral pushing force on the moving clamp 22, thereby making room for the placement plate 8 to be placed and successfully completing the placement action. When it is necessary to flexibly adjust the internal space of the cabinet 1 to accommodate various samples, pulling the sliding column 25 causes the sliding column 25 to move in a certain direction. The internal sliding column 26 slides smoothly. During the process, the spring 23 sleeved on the outer wall of the sliding column 25 is compressed. Then, the rebound force of the spring 23 pushes the moving clamp 22 to move flexibly. The fixed column 24 connected to it also slides on the surface of the tray 17, unlocking the placement plate 8 so that it can be easily disassembled. For taller samples, the layer spacing is increased to ensure that they are placed smoothly; for shorter samples, the layer spacing is reduced to achieve multi-layer stacking, maximizing the use of the vertical space of the cabinet 1, thereby greatly increasing the sample storage capacity of the unit cabinet 1 and avoiding the problem of not being able to store special-sized samples due to space limitations.
[0037] Working principle: When cabinet 1 is working, the sample box 9 will shake. The electric push rod 10 needs to be activated, which will drive the fixed base 12 to move. At the same time, the electric push rod 10 on the other side will move, which will then drive the fixed base 12 on the other side to move. This will cause the sliding blocks 15 on both sides to slide inside the slide groove 14, and then drive the slide groove 14 to slide above the platform 13. Subsequently, the clamps 16 on both sides will move towards the center, thus clamping the sample box 9 in the center. When the sampling is completed and the sample box 9 needs to be released, the electric push rods 10 on both sides will move at the same time, which will drive the sliding blocks 15 and the clamps 16 to move, thereby releasing the clamp on the object and preventing the sample box 9 from being damaged due to shaking, collision, or falling, thus improving the overall work efficiency of food inspection.
[0038] When the placement plate 8 needs to be placed, press the placement plate 8, which will drive the push column 19 to move. Then, push the column 19 to drive the sliding cone block 20 to move. Subsequently, the sliding cone block 20 will slide on the outer wall of the positioning column 21. Since the contact surface between the moving clamp 22 and the sliding cone block 20 is inclined, push the moving clamp 22 to move it, and then the placement plate 8 can be placed. When the internal space of the cabinet 1 needs to be adjusted, pull the sliding column 25. Pull the sliding column 25 to slide inside the clamping column 26, which will compress the spring 23 on the outer wall of the sliding column 25. Then, move the moving clamp 22, and then move the fixing column 24 on the support plate 17, so that the placement plate 8 can be disassembled. For food sample boxes 9 of different heights, they can be arranged closely to eliminate a large amount of redundant top space caused by the fixed spacing between the shelves. The number of samples that the sample retention cabinet can store can be significantly increased, improving space utilization efficiency.
