Description

Technical Field

[0001] This utility model relates to the field of storage technology, and in particular to a stable storage cold chain device for 2,6-difluorobenzonitrile. Background Technology

[0002] 2,6-Difluorobenzonitrile, a key intermediate in the pharmaceutical, pesticide, and other fine chemical industries, is chemically reactive and has extremely stringent requirements for storage environment. During actual production and transportation, 2,6-difluorobenzonitrile is highly susceptible to decomposition, polymerization, or packaging damage due to factors such as temperature fluctuations, humidity changes, and external shocks, leading to material deterioration and even safety risks. Therefore, developing a cold chain storage device that can accurately control environmental parameters, enhance safety protection, and improve operational stability is of great significance for ensuring the quality and storage safety of 2,6-difluorobenzonitrile.

[0003] Existing 2,6-difluorobenzonitrile storage cold chain devices mostly adopt traditional mechanical structures and technical principles. In terms of temperature control, they mainly rely on a single compressor refrigeration system and simple temperature sensors, using relays to control the compressor's start and stop, achieving coarse temperature regulation. In terms of shelving design, they usually use fixed metal shelves, directly installed at the bottom of the cabinet, lacking cushioning and shock absorption measures. Temperature and humidity monitoring is mainly based on single-point monitoring, and in terms of safety protection, they are equipped with basic temperature and humidity alarm devices.

[0004] However, existing cold chain devices have significant shortcomings in dealing with external impacts. In scenarios such as cargo handling, equipment vibration, or uneven ground, the lack of cushioning structure on the shelves leads to frequent vibrations and impacts on the goods, which can easily cause storage containers to shift, tip over, or even break, resulting in leakage of 2,6-difluorobenzonitrile. At the same time, the rigid connection between the shelves and the boxes is prone to structural loosening and component wear under long-term impacts, which not only affects the service life of the device but also leads to safety accidents due to decreased shelf stability. It cannot meet the strict requirements of 2,6-difluorobenzonitrile for storage stability and safety. Therefore, a stable storage cold chain device for 2,6-difluorobenzonitrile is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides a stable storage cold chain device for 2,6-difluorobenzonitrile, which aims to improve the problems in the existing cold chain devices where the lack of a buffer structure on the shelves leads to the displacement and tipping of cargo containers, material leakage, and damage to the shelf and box structure, posing safety hazards when subjected to external impacts.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A stable storage cold chain device for 2,6-difluorobenzonitrile includes a storage box, which provides stable refrigerated storage conditions for 2,6-difluorobenzonitrile. The storage box is fixedly connected with symmetrical support rods, and multiple shelves are slidably connected inside the support rods. Each of the multiple shelves is equipped with a buffer component.

[0008] The buffer assembly includes a shelf that is slidably connected inside the shelf. The shelf provides a basic connection and supports 2,6-difluorobenzonitrile. Multiple connecting plates are fixedly connected to the bottom of the shelf, and each connecting plate has a symmetrically connected transmission rod. The transmission rods further transmit the impact force downwards, causing a slider to slide on the outer wall of the connecting rod, thus achieving a force-relieving effect. Multiple connecting rods are fixedly connected inside the shelf, and a slider is slidably connected to one end of each transmission rod. The slider is slidably connected to the outer wall of each connecting rod. Symmetrically arranged springs are provided on the outer wall of each connecting rod. These springs absorb and buffer impact or vibration through their elastic deformation, ensuring the storage stability of 2,6-difluorobenzonitrile. One end of each spring is fixedly connected to the inner wall of the shelf, and the other end is fixedly connected to the side wall of the slider. Symmetrically arranged adjustment components are provided at the top of the shelf.

[0009] As a further description of the above technical solution:

[0010] The adjustment component includes a connecting block and a fixing plate. The bottom of the connecting block is fixedly connected to the upper surface of the shelf. The function of the connecting block is to provide stable support and connection for the adjustment component and ensure its movement stability. The outer wall of the fixing plate is fixedly connected to the inside of the connecting block.

[0011] As a further description of the above technical solution:

[0012] Both sides of the fixed plate are fixedly connected to a retractable rod, and one end of each retractable rod is fixedly connected to a transmission disc. The function of the transmission disc is to further transmit the force of the user downwards, thereby causing the retractable rod to retract and deform.

[0013] As a further description of the above technical solution:

[0014] Both transmission discs are fixedly connected to levers on their outer walls. The levers facilitate quick driving of the adjustment components by the user. Each of the two transmission discs is fixedly connected to a limit post at one end.

[0015] As a further description of the above technical solution:

[0016] The support rod has multiple slots inside, and the limiting post engages with the slots. Through the engagement of the slots and the limiting post, the adjustment component can be quickly locked and unlocked.

[0017] As a further description of the above technical solution:

[0018] Both levers are slidably connected inside the connecting block, and springs are provided on the outer walls of both retraction rods. The function of springs is to provide elastic restoring force for the adjustment assembly to ensure stable movement of the adjustment assembly.

[0019] As a further description of the above technical solution:

[0020] One end of each of the two springs is fixedly connected to the side wall of the fixed disk, and the other end is fixedly connected to the side wall of the transmission disk.

[0021] As a further description of the above technical solution:

[0022] The lever is made of rubber, which is used to enhance the user experience and increase friction with the user's hand.

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, the sliding of the shelf inside the shelf further drives the transmission rod to deflect, thereby causing the slider to slide on the outer wall of the connecting rod, compressing the spring and causing elastic deformation, thus achieving the effect of quickly buffering the vibration and impact on the shelf. This solves the safety problems of cargo container breakage and leakage and shelf structure damage caused by impact in the prior art, and improves the stability of goods during storage.

[0025] 2. In this utility model, by pressing the lever simultaneously, the transmission disc slides inside the connecting block, which further drives the second spring and the retraction rod to undergo elastic deformation, thereby causing the limit post to disengage from the slot and unlock, thus achieving the effect of quickly adjusting the height position of the shelf. This solves the problem of fixed shelf height in the prior art, which cannot adapt to the storage needs of different specifications of goods, and improves the utilization rate of warehouse space and the efficiency of goods storage and retrieval.

[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 The present invention provides an embodiment of a 2,6-difluorobenzonitrile stable storage cold chain device, comprising a storage box 1, wherein symmetrical support rods 9 are fixedly connected inside the storage box 1, the support rods 9 are used to ensure that the shelves 2 can be placed stably and can be adjusted when needed, and multiple shelves 2 are slidably connected inside the support rods 9, and each of the multiple shelves 2 is provided with a buffer component, the buffer component is used to effectively reduce the impact of vibration or other external factors on the stored items during transportation;

[0035] The buffer assembly includes a shelf 3, which is slidably connected inside the shelf 2. The shelf 3 ensures the stable storage of items inside the shelf 2 during transportation. Multiple connecting plates 4 are fixedly connected to the bottom of the shelf 3. Each connecting plate 4 has a symmetrically connected transmission rod 5 inside. The transmission rod 5 further transmits vibration downwards. Multiple connecting rods 6 are fixedly connected inside the shelf 2. Each transmission rod 5 has a rotatably connected slider 7 at one end. The slider 7 is slidably connected to the outer wall of the connecting rod 6. Symmetrically connected springs 8 are installed on the outer wall of the connecting rod 6. The springs 8 alleviate excessive vibration or pressure fluctuations during transportation, thus ensuring the stability of 2,6-difluorobenzonitrile during storage. One end of each spring 8 is fixedly connected to the inner wall of the shelf 2, and the other end is fixedly connected to the side wall of the slider 7. Symmetrically connected adjustment components are installed at the top of the shelf 2, allowing for height adjustment as needed, further improving the adaptability of the device.

[0036] Specifically, when the cold chain equipment faces scenarios such as impacts from cargo handling, vibrations from equipment operation, and uneven ground, causing the shelves to sway, goods to tip over, or packaging to be damaged, the user first places 2,6-difluorobenzonitrile on the surface of the shelf 3 and stores it in the storage box 1 for refrigeration. To ensure that 2,6-difluorobenzonitrile is not affected by external vibrations or compression during storage, when shaking or compression occurs during the placement or handling of items, the shelf 3 will slide inside the shelf 2. At this time, the sliding of the shelf 3 acts on the transmission rod 5 through the connecting plate 4, causing the transmission rod 5 to deflect. The deflection of the transmission rod 5 further drives the slider 7 to slide along the outer wall of the connecting rod 6, thereby squeezing the spring 8, causing it to undergo elastic deformation, absorbing and mitigating impact vibrations, thereby achieving stable support for 2,6-difluorobenzonitrile and preventing it from being affected by vibrations.

[0037] Reference Figure 4 and Figure 5The adjustment assembly includes a connecting block 10 and a fixed plate 11. The bottom of the connecting block 10 is fixedly connected to the upper surface of the shelf 2. The outer wall of the fixed plate 11 is fixedly connected to the inside of the connecting block 10. Retraction rods 12 are fixedly connected to both sides of the fixed plate 11. The function of the retraction rods 12 is to limit the movement of the second spring 17, prevent excessive deformation of the second spring 17, and also to transmit power. A transmission plate 13 is fixedly connected to one end of each retraction rod 12. A lever 16 is fixedly connected to the outer wall of each of the two transmission plates 13. The lever 16 facilitates quick operation of the adjustment assembly by the user, ensuring its usability. For ease of use, one end of each of the two transmission discs 13 is fixedly connected to a limiting post 15. The support rod 9 has multiple slots 14 inside, and the limiting post 15 engages with the slots 14. Both levers 16 are slidably connected inside the connecting block 10. The outer walls of both retraction rods 12 are provided with springs 17. The function of springs 17 is to provide necessary elastic support for the adjustment components, so that the adjustment process can be smoothly transitioned, while providing a certain elastic restoring force. One end of each spring 17 is fixedly connected to the side wall of the fixed disc 11, and the other end is fixedly connected to the side wall of the transmission disc 13. The levers 16 are made of rubber.

[0038] Specifically, when the position of shelf 2 needs to be adjusted to meet different storage requirements, the user can press the lever 16. Under the pressure, the transmission disc 13 will slide inside the connecting block 10 and squeeze the retractable rod 12, causing the retractable rod 12 to retract. At the same time, the retraction process will apply pressure to the second spring 17, causing it to undergo elastic deformation and store elastic potential energy. The movement of the transmission disc 13 will also drive the limiting post 15 to retract into the connecting block 10, disengaging from the slot 14, thereby unlocking the device. This allows the user to quickly adjust the position and height of shelf 2 to adapt to different storage needs. After the adjustment is completed, the elastic restoring force of the second spring 17 will push the limiting post 15 to reset and re-engage it in the slot 14, ensuring that the position of shelf 2 is firmly fixed. This ensures the stability, flexibility, and convenient adjustment function of the device, making the storage of 2,6-difluorobenzonitrile safer and more efficient.

[0039] Working Principle: When using this 2,6-difluorobenzonitrile stable storage cold chain device, the 2,6-difluorobenzonitrile is first placed on the surface of the shelf 3 by personnel, and then refrigerated in the storage box 1. When the 2,6-difluorobenzonitrile is shaken or squeezed during placement or handling, the shelf 3 will slide inside the shelf 2. The sliding of the shelf 3 further drives the connecting plate 4 to press the transmission rod 5, causing the transmission rod 5 to deflect synchronously. The deflection of the transmission rod 5 further drives the slider 7 to slide on the outer wall of the connecting rod 6. The sliding of the slider 7 compresses the spring 8, causing the spring 8 to deform elastically, thereby achieving the effect of quickly absorbing and buffering impact vibration, providing stable support for the 2,6-difluorobenzonitrile. When it is necessary to adjust the shelf 2... When the position is adjusted to meet different storage needs, the user can simultaneously press the lever 16. Under the pressure, the transmission disc 13 will slide inside the connecting block 10. The sliding of the transmission disc 13 will compress the retraction rod 12, causing it to retract. At the same time as the retraction rod 12 retracts, it will also compress the second spring 17, causing the second spring 17 to undergo elastic deformation and store elastic potential energy. As the transmission disc 13 moves, it will also drive the limiting post 15 to retract into the connecting block 10, thereby disengaging from the slot 14 and unlocking it. After unlocking, the user can quickly adjust the position and height of the shelf 2 to meet different storage needs. After adjustment, the elastic restoring force of the second spring 17 will push the limiting post 15 back to reset, causing it to re-enter the slot 14 for fixation.

[0040] 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
