[0032] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0033] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the invention is not limited to the specific embodiments disclosed below.

[0034] In practical use, it was found that the current food sample refrigerators generally adopt a hollow independent placement slot structure, which uses a through cold air channel to achieve uniform cooling of the sample from all sides, and the temperature difference can be controlled within ±1℃. At the same time, the slots prevent direct contact between adjacent samples, significantly reducing the risk of cross-contamination and reducing dead zones in cold air flow, thus improving cooling efficiency. However, this design brings the drawback of manual removal and placement of each slot. When the same batch of samples reaches the expiration date, the management personnel need to remove dozens of sample boxes one by one. In high-frequency sample retention scenarios such as large-scale canteens and central kitchens, multiple batches and hundreds of sample boxes need to be processed every day. The existing single-slot manual mode has become an efficiency bottleneck and also increases labor costs. To solve the above problems, the following structure was invented.

[0035] like Figures 1-12 The food sample retention refrigerator shown includes a cabinet 1 and a waste bin 47. The cabinet 1 is equipped with a display screen 2 and a weighing mechanism 3. A rear frame 4 is fixedly connected to the rear of the cabinet 1, and a fixed bracket 5 is fixedly connected to the front of the rear frame 4. Several sliding brackets 6 are equidistantly slidably connected between the fixed bracket 5 and the rear frame 4. Each fixed bracket 5 has a separate door 7 with an electromagnetic lock hinged to its front relative to the front position of the sliding brackets 6. The separate doors 7 allow for individual protection of the food samples on each sliding bracket 6 and are connected to the display screen 2. The doors are opened by a controller, further enhancing the safety of the sample retention refrigerator. The tops of the several sliding brackets 6 slide equidistantly. Four sample frames 8 are connected. Several circular grooves 9 are equidistantly opened through the top of the four sample frames 8. A U-shaped groove is opened at the top of the sample frame 8. A U-shaped rod 10 is provided in the U-shaped groove. A limiting mechanism is provided on the U-shaped rod 10 to limit its position. A sliding block 11 is longitudinally slidably connected to the inner side of the rear frame 4. A material picking mechanism for removing the U-shaped rod 10 is provided on the sliding block 11. Slide grooves are opened on the side wall of the rear frame 4 at the position relative to the rear of the sliding frame 6. T-shaped blocks 12 are fixedly connected to the rear side of the sliding frame 6 at the position relative to the position inside the slide groove. A return spring 50 is fixedly connected between the bottom end of the slide groove and the bottom end of the T-shaped block 12. A downward moving mechanism is also provided to drive the sliding frame 6 to move downward.

[0036] The limiting mechanism includes a limiting block 13. Side grooves are provided on both sides of the top of the U-shaped rod 10. Several pairs of limiting blocks 13 are provided, and several pairs of limiting blocks 13 are slidably connected to the inside of the side grooves. The limiting blocks 13 are L-shaped. Limiting grooves 14 are provided on the inside of the U-shaped grooves relative to the side of the limiting blocks 13. The side ends of the limiting blocks 13 are inserted into the inside of the limiting grooves 14. The inside of the limiting blocks 13 is inclined. Limiting springs 15 are fixedly connected between the side wall of the limiting blocks 13 and the inside of the side grooves. The opening of the U-shaped groove is located on the side near the separate door 7. The U-shaped rod 10 is made of iron.

[0037] The material handling mechanism includes a drive motor 16, and U-shaped frames 17 are fixedly connected to both sides of the top of the sliding block 11. A flipping frame 18 is rotatably connected to the inside of the U-shaped frame 17, and a T-shaped plate 19 is slidably connected to the inside of the flipping frame 18. The bottom of the T-shaped plate 19 is respectively provided with an upper groove 20 and a lower groove 21. Both sides of the upper groove 20 are inclined, and the lower groove 21 is inclined on the side closer to the upper groove 20. An upper electric telescopic cylinder 24 is fixedly connected to the side wall of the flipping frame 18. A T-shaped extrusion plate 25 is fixedly connected to the output end of the upper electric telescopic cylinder 24. An electromagnet 31 is fixedly connected through the top of both the upper groove 20 and the lower groove 21.

[0038] The T-shaped plate 19 has a storage groove on its side wall. An L-shaped extrusion rod 22 is slidably connected to the inside of the storage groove. The L-shaped extrusion rod 22 is inclined on the side near the lower groove 21. An upper round rod 23 is fixedly connected to the rear side of the L-shaped extrusion rod 22. An upper right-angle plate 26 with an inclined surface is fixedly connected to the bottom end of the T-shaped extrusion plate 25 relative to the position below the upper round rod 23. An L-shaped locking rod 28 is fixedly connected to the side wall of the upper round rod 23. The L-shaped locking rod 28 passes through the side wall of the T-shaped plate 19. The side wall of the flip frame 18 has a locking groove 29 that matches the L-shaped locking rod 28. The side wall of the L-shaped locking rod 28 is inserted into the inside of the locking groove 29.

[0039] A storage spring 30 is fixedly connected between the inner side of the storage slot and the side wall of the L-shaped extrusion rod 22, and a return spring 27 is fixedly connected between the bottom end of the flip frame 18 and the bottom end of the T-shaped plate 19.

[0040] The lowering mechanism includes a pair of lower electric telescopic cylinders 34. A pair of top grooves are formed through the top of the sliding block 11. Each lower electric telescopic cylinder 34 is fixedly connected to the inner side of one of the top grooves. A middle groove is formed between the top of the sliding block 11 and the top groove. A U-shaped sliding frame 35 is longitudinally slidably connected to the inner side of the middle groove. Inner grooves are formed on both sides of the middle groove. Positioning plates 36 for supporting the T-shaped block 12 are laterally slidably connected to the inner side of each inner groove. The positioning plates 36 restrict the downward movement of the T-shaped block 12, ensuring stability during subsequent sample placement and storage. A lower round rod is fixedly connected to the rear side of each positioning plate 36. 37. The rear end of the lower round rod 37 is set as a smooth arc surface. Several positioning springs 38 are fixedly connected between the inner side of the inner groove and the side wall of the positioning plate 36. The top of the positioning plate 36 is inclined on the side closest to each other. When the T-shaped block 12 deviates and fails to be fully reset in the subsequent reset, the T-shaped block 12 is pushed upward by the inclined surface of the positioning plate 36, thereby ensuring the reset of the T-shaped block 12. The inner side of the U-shaped sliding frame 35 is slidably connected to an L-shaped push plate 39. The bottom end of the L-shaped push plate 39 is fixedly connected to a release block 40, and both sides of the release block 40 are inclined. L-shaped grooves 41 are opened through both sides of the middle groove.

[0041] Guide rods 42 are fixedly connected to both sides of the outer wall of the L-shaped push plate 39. Straight grooves 43 are opened through both sides of the outer wall of the U-shaped slide frame 35. The side ends of the guide rods 42 are set through the straight grooves 43 and the L-shaped grooves 41. The output end of the lower electric telescopic cylinder 34 is fixedly connected to the top plate 44. The bottom end of the top plate 44 is fixedly connected to the lower right-angle plate 45 with an inclined surface. The rear side of the L-shaped push plate 39 has a rear groove. A rear spring 46 is fixedly connected between the inner side of the rear groove and the inner side of the U-shaped slide frame 35.

[0042] A notch 48 is provided on the rear side of the waste box 47, and a push rod 49 is fixedly connected to the top of the notch 48.

[0043] During the use of the food sample retention refrigerator, first open the cabinet door of the cabinet 1, then open the corresponding individual door 7, then take out the sample frame 8, and put the sample boxes into the round groove 9 in sequence. At this time, the lid of the sample box will be stuck above the sample frame 8 and located above the U-shaped rod 10. Then push the sample frame 8 back, close the individual door 7 and the cabinet door of the cabinet 1, and the food sample retention refrigerator will then refrigerate and store the food samples.

[0044] When the food sample retention period expires and the manager needs to remove the same batch of food samples from the sliding rack 6, the upper electric telescopic cylinder 24 is first activated to drive the T-shaped pressing plate 25 and the upper right-angle plate 26 downwards. During this process, because the L-shaped locking rod 28 is inserted into the locking groove 29, restricting the downward movement of the T-shaped plate 19, and the upper round rod 23 and the L-shaped pressing rod 22 can only move laterally inside the storage groove, when the upper right-angle plate 26 moves downwards, the inclined surface of the upper right-angle plate 26 will press against the upper round rod 23 and the L-shaped locking rod 28. 8 moves laterally within the storage slot, simultaneously stretching the storage spring 30, thereby extending the L-shaped locking rod 28 and causing it to slide. Subsequently, when the upper round rod 23 moves to the top of the inclined surface of the upper right-angle plate 26, it will cause the L-shaped locking rod 28 to slide out from the locking slot 29, releasing the sliding restriction on the T-shaped plate 19. At the same time, the T-shaped pressing plate 25 moves to the top of the T-shaped plate 19. As the T-shaped pressing plate 25 continues to move downward, it will push the T-shaped plate 19 downward and compress the return spring 27.

[0045] During the downward movement of the T-shaped plate 19, the upper groove 20, lower groove 21, and L-shaped extrusion rod 22 will move downward together. At this time, the inclined surfaces on both sides of the upper groove 20 will press the inclined surfaces of one pair of limiting blocks 13 on one of the sample frames 8, and the inclined surfaces of the lower groove 21 and L-shaped extrusion rod 22 will press the inclined surfaces of another limiting block 13 on the other sample frame 8. Since the limiting block 13 can only move laterally in the side groove, as the T-shaped plate 19 moves downward, the inclined surfaces of the upper groove 20, lower groove 21, and L-shaped extrusion rod 22 will press the inclined surfaces of the limiting block 13, causing the limiting block 13 to slide out from the limiting groove 14, releasing the position restriction on the U-shaped rod 10, and compressing the limiting spring 15. Then, the bottom end of the T-shaped plate 19 moves to the top end of the U-shaped rod 10, which can control the electromagnet 31 to be energized and attract and fix the U-shaped rod 10.

[0046] Then, the lower electric telescopic cylinder 34 is started to drive the top plate 44 and the lower right-angle plate 45 to move down. During this process, since the guide rod 42 is inserted into the L-shaped groove 41 and the straight groove 43, and the guide rod 42 is located at the lateral end of the L-shaped groove 41, the guide rod 42 can only slide laterally. Therefore, when the lower right-angle plate 45 moves down, the inclined surface of the lower right-angle plate 45 will squeeze the guide rod 42 to move laterally, and drive the guide rod 42 to move laterally at the lateral end of the L-shaped groove 41 and in the straight groove 43. At the same time, it drives the L-shaped push plate 39 and the release block 40 to move forward, and stretches the rear spring 46. At this time, the inclined surfaces on both sides of the release block 40 will squeeze the arc surface of the lower round rod 37, causing the lower round rod 37 to slide to both sides. At the same time, it drives the positioning plate 36 to move away from below the T-shaped block 12, and compresses the positioning spring 38, thereby releasing the downward restriction on the T-shaped block 12. Then, the lateral end of the L-shaped push plate 39 moves to the top of the T-shaped block 12.

[0047] Meanwhile, the guide rod 42 moves to the corner of the L-shaped groove 41. As the lower right-angle plate 45 continues to move downward, it will push against the guide rod 42 and move downward within the L-shaped groove 41, thereby driving the L-shaped push plate 39 and the release block 40 to move downward together, which in turn drives the T-shaped block 12 to move downward. During this process, the lower round rod 37 will gradually move away from the release block 40, but the T-shaped block 12 moves between the positioning plates 36, restricting the reset of the positioning plates 36, so it will not be affected. Thus, the downward movement of the T-shaped block 12 will drive the sliding frame 6 and the sample frame 8 to move downward together, and gradually compress the return spring 50. The sample box lid rests against the U-shaped rod 10, thus separating the sample frame 8 from the U-shaped rod 10. Then, the operator can open the cabinet door 1 and the separate door 7, pass the notch 48 of the waste box 47 through multiple U-shaped rods 10, and position the push rod 49 above the U-shaped rod 10. Then, when the waste box 47 is fully inserted, the push rod 49 can be placed in front of the T-shaped block 12 and released from the top of the U-shaped rod 10. Finally, the waste box 47 is pulled out, and all the sample boxes are taken out together by the push rod 49, which can realize the rapid sampling of the device. Finally, control all the equipment to run in reverse and repeat the above operation to reset.

[0048] In summary, the above structural design allows for the rapid attachment of U-shaped rods 10 to the same batch of sample boxes on the sliding rack 6 when food samples expire. Subsequently, the downward movement mechanism releases the restriction on the sliding rack 6 and drives it downward. Under the support of the U-shaped rods 10, the sample boxes are separated from the sample frames 8, facilitating the quick removal of the same batch of food samples from the sliding rack 6 without requiring personnel to remove them one by one, greatly improving the device's convenience. Furthermore, the waste box 47 allows for the rapid pulling out of the separated sample boxes all at once, further enhancing the device's convenience.

[0049] Based on the above embodiments, it was found during use that although the above structure can quickly remove the sample box, the material retrieval structure can only be used on one sliding rack 6, and cannot retrieve sample boxes on multiple sliding racks 6 in the sample retention refrigerator, which cannot meet the user's needs. To solve the above problems, the above structure has been further improved.

[0050] A pair of drive motors 16 are provided, and both drive motors 16 are fixedly connected to the side wall of the U-shaped frame 17. The output end of the drive motor 16 passes through the inside of the U-shaped frame 17 and is fixedly connected to the side wall of the flip frame 18.

[0051] A lead screw 32 is rotatably connected to the inner side of the rear frame 4, and a moving motor 33 is fixedly connected to the top of the housing 1. The lead screw 32 is threaded through and connected to the inner side wall of the sliding block 11. The output end of the moving motor 33 passes through the housing 1 and the rear frame 4 and is fixedly connected to the top of the lead screw 32.

[0052] When it is necessary to take samples from the sample boxes on different sliding frames 6, after the equipment is reset, the drive motor 16 is started to rotate the flipping frame 18, which in turn drives the T-block 12 and the retracted L-shaped extrusion rod 22 to flip upward, so that the T-block 12 is put into the rear frame 4. Then the moving motor 33 is started to rotate the lead screw 32, which in turn drives the threaded sliding block 11 to move downward, so that the sliding block 11 moves to the position next to the corresponding sliding frame 6. The drive motor 16 is then reversed to flip the T-block 12 over.

[0053] In summary, the above-described structure allows the material handling mechanism to be stored away. Then, driven by the moving motor 33, the sliding block 11 can be moved to the side of each sliding rack 6 to quickly take samples from the sample boxes on each sliding rack 6 in the sample retention refrigerator, greatly improving the convenience of the device.

[0054] The foregoing has shown and described the basic principles, main features, and advantages of the present invention.

[0055] Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of the present invention. Various changes and modifications can be made to the present invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
