Description
Technical Field
[0001] This utility model relates to the field of storage rack technology, specifically to a multi-layer independent temperature zone controlled storage rack structure. Background Technology
[0002] In modern warehousing and storage management, the temperature requirements for different items are becoming increasingly diverse. For example, vaccines in the pharmaceutical field need to be refrigerated at 2-8℃, while some biological agents need to be frozen at -20℃. In the fresh food industry, ice cream needs to be stored below -18℃, while fruits and vegetables are suitable for preservation in an environment of 0-10℃. Chemical reagents and biological samples in laboratories also often have their own specific temperature requirements.
[0003] Existing storage racks mostly use a fixed structure for the height of each shelf, and the spacing between shelves cannot be adjusted once they are manufactured. This design leads to serious space utilization inefficiency when dealing with storage items of different sizes. Therefore, a multi-layer independent temperature zone control storage rack structure is needed, which can independently adjust the height of each shelf. Utility Model Content
[0004] To address this issue, this utility model provides a multi-layer independent temperature zone controlled storage rack structure. By combining the fixed rack assembly and the layer height adjustment assembly, it solves the problem that storage racks often use a fixed structure in their layer height design, and the layer spacing cannot be adjusted once the rack is manufactured.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a multi-layer independent temperature zone controlled storage rack structure, including a storage rack, a sealed door connected to one side of the storage rack, a fixed frame assembly inside the storage rack, multiple layer height adjustment components inside the fixed frame assembly, the fixed frame assembly including a fixed frame, the fixed frame being fixedly disposed inside the storage rack, two guide rails fixedly disposed on both sides of the inner side wall of the fixed frame, each of the multiple guide rails having a limit hole, two electrically controlled magnetic suction plates fixedly disposed on both sides of the fixed frame, multiple layer temperature control modules fixedly disposed on one side of the fixed frame, the layer height adjustment component including a shelf, a baffle plate fixedly disposed at the bottom of the shelf, two round holes on both sides of the shelf, miniature springs disposed inside the multiple round holes, a magnetically attached movable column disposed at one end of each of the multiple miniature springs, a layer height adjustment component disposed inside the baffle plate, the layer height adjustment component including a servo motor, a rotating shaft fixedly disposed at the output end of the servo motor, a gear fixedly disposed on the outside of the rotating shaft, and a rack disposed on one side of the gear.
[0006] Preferably, the electrically controlled magnetic chuck corresponds to the guide rail.
[0007] Preferably, the shelf is disposed inside the fixed frame and slidably connected to the fixed frame, and the shelf is disposed between multiple guide rails and slidably connected to the multiple guide rails.
[0008] Preferably, the baffle plate contacts the fixed frame and is slidably connected to the fixed frame.
[0009] Preferably, the micro spring is disposed inside the circular hole, one end of the micro spring is fixedly connected to one side wall of the circular hole, and the other end of the micro spring is fixedly connected to one end of the magnetic movable column.
[0010] Preferably, one end of the magnetically attached movable column is disposed inside the circular hole and slidably connected to the circular hole, and the other end of the magnetically attached movable column extends into the limiting hole and slidably connects to the limiting hole.
[0011] Preferably, the servo motor is located between the fixed frame and the storage rack, and the servo motor is fixedly connected to one side wall of the fixed frame.
[0012] Preferably, one end of the rotating shaft passes through one side wall of the fixed frame and is connected to the side wall of the fixed frame via a bearing, and one end of the rotating shaft is connected to one side wall of the baffle plate via a bearing.
[0013] Preferably, the gear meshes with the rack, the top of the rack is fixedly connected to the layer plate, and the bottom of the rack is fixedly connected to the baffle plate.
[0014] The present invention has the following advantages: Through the synergistic effect of the fixed frame assembly and the shelf height adjustment assembly, the height of each shelf can be adjusted independently. With the help of the electronically controlled magnetic suction plate and the magnetic movable column, the shelf can be quickly fixed or unlocked. Then, the servo motor, gear and rack transmission can achieve precise lifting and lowering. The adjustment of each shelf does not interfere with each other, which can flexibly adapt to the storage needs of items of different heights and effectively solve the problem of fixed shelf height in traditional storage racks. Multiple temperature control modules on one side of the fixed frame allow for independent temperature control of each corresponding layer, meeting the temperature requirements of different items. Meanwhile, the baffle at the bottom of the shelf is in close contact with and slidably connected to the fixed frame, ensuring that the gaps between layers are always blocked during the adjustment of the shelf height. Combined with the sealing door, this significantly reduces crosstalk between layers and ensures the stability of the temperature in each zone. Attached Figure Description

[0020] See attached document Figure 1 - Appendix Figure 5This utility model provides a multi-layer independent temperature zone controlled storage rack structure, including a storage rack 10, a sealing door 20 connected to one side of the storage rack 10, a fixing frame assembly 30 inside the storage rack 10, multiple shelf height adjustment components 40 inside the fixing frame assembly 30, and a fixing frame 31 fixedly disposed inside the storage rack 10. Two guide rails 32 are fixedly disposed on each of the two inner side walls of the fixing frame 31, and limit holes 33 are formed inside each of the multiple guide rails 32. Two electrically controlled magnetic suction plates 34 are fixedly disposed on both sides of the fixing frame 31. Multiple temperature control modules 35 are fixedly installed on one side of frame 31. The height adjustment component 40 includes a shelf 41. A baffle 42 is fixedly installed at the bottom of the shelf 41. Two round holes 43 are opened on both sides of the shelf 41. Miniature springs 44 are installed inside the multiple round holes 43. A magnetic movable column 45 is provided at one end of the multiple miniature springs 44. A height adjustment component is provided inside the baffle 42. The height adjustment component includes a servo motor 46. A rotating shaft 47 is fixedly installed at the output end of the servo motor 46. A gear 48 is fixedly sleeved on the outside of the rotating shaft 47. A rack 49 is provided on one side of the gear 48. In this implementation scheme, in order to achieve the purpose of individually adjusting the shelf height, when adjusting the shelf height, a power-off command is sent to the corresponding electrically controlled magnetic suction plate 34 through the control panel or smart terminal. After the magnetic force disappears, the miniature spring 44 in the round hole 43 pulls the magnetic movable column 45 to retract from the limiting hole 33 of the guide rail 32, and the shelf 41 is disengaged. Then, the control panel starts the servo motor 46 of that shelf, and the rotating shaft 47 drives the gear 48 to rotate. Through the meshing transmission with the rack 49, the shelf 41 slides smoothly along the guide rail 32. After reaching the preset height, the servo motor 46 stops, the electrically controlled magnetic suction plate 34 is energized to generate magnetic force, attracting the magnetic movable column 45 to overcome the spring tension and re-embed into the corresponding limiting hole 33 to complete the fixation. Because each shelf component and control circuit is independent, the shelf height can be adjusted independently without interference, meeting the storage needs of items of different heights. To achieve the goal of drawing the magnetically attached movable column 45 into the limiting hole 33 by the magnetic force generated when the electrically controlled magnetic suction plate 34 is energized, the device employs the following technical solution: the electrically controlled magnetic suction plate 34 corresponds to the guide rail 32; the shelf 41 is located inside the fixed frame 31 and slidably connected to it; the shelf 41 is located between multiple guide rails 32 and slidably connected to them; a miniature spring 44 is located inside the circular hole 43; one end of the miniature spring 44 is fixedly connected to one side wall of the circular hole 43; the other end of the miniature spring 44 is fixedly connected to one end of the magnetically attached movable column 45; one end of the magnetically attached movable column 45 is located inside the circular hole 43 and slidably connected to it; the other end of the magnetically attached movable column 45 extends into the limiting hole 33 and slidably connected to it; the electrically controlled magnetic suction plate 34 is positioned opposite to the guide rail 32 to ensure that the generated magnetic force can accurately... The magnetic movable columns 45 on both sides of the shelf 41 are magnetically attached. When the electrically controlled magnetic plate 34 is energized, the magnetic force generated breaks through the tension of the micro spring 44 and forms an attractive force on the magnetic movable columns 45 in the direction of the guide rail 32. Since one end of the magnetic movable column 45 is located in the circular hole 43 and is slidably connected to the circular hole 43, it can move along the axial direction of the circular hole 43 under the action of magnetic force. At the same time, the shelf 41 is located between multiple guide rails 32 and is slidably connected to the guide rails 32 to ensure the relative position of the shelf 41 and the guide rails 32 is stable, so that the magnetic movable column 45 can be accurately aligned with the limiting hole 33 on the guide rail 32. Finally, under the magnetic drive, the magnetic movable column 45 overcomes the elastic force of the micro spring 44 and extends out of the circular hole 43, accurately embedding into the corresponding limiting hole 33. With the sliding connection between the shelf 41 and the fixed frame 31, the shelf 41 is stably fixed in the current position. To achieve the purpose of adjusting the floor height, this device adopts the following technical solution: A shielding plate 42 contacts and slides on the fixed frame 31; a servo motor 46 is located between the fixed frame 31 and the storage rack 10, and is fixedly connected to one side wall of the fixed frame 31; one end of a rotating shaft 47 passes through one side wall of the fixed frame 31 and is connected to it via a bearing; one end of the rotating shaft 47 is connected to one side wall of the shielding plate 42 via a bearing; a gear 48 meshes with a rack 49; the top of the rack 49 is fixedly connected to the shelf 41, and the bottom of the rack 49 is fixedly connected to the shielding plate 42. When the floor height needs to be adjusted, the servo motor 46, as a power source, provides stable driving force because it is fixed to one side wall of the fixed frame 31. The output end of the servo motor 46 drives the rotating shaft 47 to rotate. One end of the rotating shaft 47 is connected to one side wall of the fixed frame 31 via a bearing, and the other end is connected to one side wall of the shielding plate 42 via a bearing. This connection method ensures the stability of the rotation of the shaft 47 and effectively transmits power to the area of the baffle plate 42. The gear 48 fixedly sleeved on the outside of the shaft 47 rotates together with the shaft 47. Since the gear 48 meshes with the rack 49, the rotational motion of the gear 48 is converted into the linear motion of the rack 49. The top of the rack 49 is fixedly connected to the shelf 41 and the bottom is fixedly connected to the baffle plate 42, so that the linear motion of the rack 49 drives the shelf 41 and the baffle plate 42 to move synchronously. The baffle plate 42 contacts and slides with the fixed frame 31, and the shelf 41 is also slidably connected with the fixed frame 31 and the guide rail 32. These sliding connections provide guidance and constraints for the movement of the shelf 41 and the baffle plate 42, ensuring that they can move up and down stably along the fixed frame 31, thereby realizing the adjustment of the shelf height. In the whole process, the components work together to transmit the power of the servo motor in an orderly manner and convert it into the lifting motion of the shelf, accurately completing the adjustment of the shelf height.
[0021] The usage process of this utility model is as follows: When using this utility model, a control panel is set to control the operation of the electrically controlled magnetic suction plate 34, the layer temperature control module 35, and the servo motor 46. According to the height of the items to be stored, the corresponding layer height adjustment component 40 is set. During operation, an adjustment command is sent through the control panel outside the storage rack 10 or the associated smart terminal. After receiving the command, the electrically controlled magnetic suction plates 34 on both sides of the fixed frame 31 are de-energized, and the magnetic force disappears. At this time, the micro spring 44 in the round hole 43 restores its elastic deformation and pulls the magnetic movable column 45. The shelf 41 pops out from the limiting hole 33 of the guide rail 32, releasing its fixed state. Then, the shelf height adjustment component activates: the servo motor 46 receives a signal and drives the rotating shaft 47 to rotate, causing the externally fixed gear 48 to rotate synchronously. The gear 48 meshes with the rack 49, allowing the shelf 41 to rise and fall smoothly under the guidance of the guide rails 32 on both sides. When the shelf 41 reaches the preset height, the servo motor 46 stops, and the electrically controlled magnetic suction plate 34 is re-energized to generate magnetic force, attracting the magnetically attached movable column 45 to overcome the elasticity of the micro-spring 44 and accurately embed it again at the corresponding height. Within the limiting hole 33, the height of the layer is fixed. Each layer height adjustment component 40 operates independently and can be set to different heights without interference. After the layer height is adjusted, an independent target temperature is set for each layer through the layer temperature control module 35 on one side of the fixing frame 31. The layer temperature control module 35 monitors the temperature of the corresponding layer in real time and dynamically adjusts it through the built-in temperature control element (such as a semiconductor cooling chip). The baffle plate 42 at the bottom of the shelf 41 is in close contact with the fixing frame 31, and always keeps the gap between layers blocked during the lifting and lowering of the shelf, in conjunction with the sealing door 20. The sealed environment effectively reduces cold crosstalk between layers. During daily use, items are placed on the corresponding shelf 41 with the appropriate height and temperature. After closing the sealing door 20, the system automatically enters a constant temperature maintenance state. The layer temperature control module 35 continuously records the temperature data of each layer. If an abnormal temperature occurs, an audible and visual alarm or a notification will be sent to the smart terminal. When it is necessary to retrieve or place items or adjust the storage plan, the layer spacing can be flexibly changed by repeating the above layer height adjustment steps to meet the storage needs of items of different sizes and achieve efficient and accurate multi-layer independent temperature zone management.
[0022] The above description is merely a preferred embodiment of this utility model. Any person skilled in the art may modify this utility model or modify it into an equivalent technical solution using the technical solutions described above. Therefore, any simple modifications or equivalent substitutions made based on the technical solutions of this utility model are within the scope of protection claimed by this utility model.
