Description

Technical Field

[0001] This utility model relates to the field of food transportation equipment technology, specifically a temperature-sensitive cold chain food transportation box for high-speed rail. Background Technology

[0002] Meals on high-speed trains are transferred to the carriages via insulated boxes when the train stops at the platform. To ensure freshness and safety during transport, a low-temperature cold chain is typically used, and the food is reheated before consumption. Most existing low-temperature insulated boxes have a simple structure, generally containing ice packs inside an insulated box to maintain a low temperature. The ice packs are sealed and contain a refrigerant. After being subjected to low-temperature treatment, the refrigerant solidifies into ice, providing a low-temperature environment. When used, it absorbs heat and liquefies. It can then be removed and placed in a freezer or other freezing equipment to solidify, allowing for reuse. Currently, meal boxes are often placed directly on top of the ice packs without any partitions. If food spills during transport, the ice packs can easily become contaminated.

[0003] When recycling and reusing ice boxes, cleaning uncontaminated ice boxes is relatively convenient, requiring only a simple rinse. However, for ice boxes contaminated with soup, traditional and convenient cleaning methods are unlikely to remove and disinfect the contaminants, thus failing to guarantee the hygiene and safety of the food inside the low-temperature insulated box that uses the ice boxes. Thoroughly cleaning contaminated ice boxes would increase overall costs and significantly reduce the efficiency of food delivery. Summary of the Invention

[0004] The purpose of this utility model is to provide a special temperature-sensitive cold chain food transport box for high-speed rail, which has a membrane inside the box to separate the ice box and the food box, thus solving the problems in the prior art.

The diaphragm is detachably installed between the bottom plate and the top wall of the inner cavity of the box. The diaphragm has a first insert post on its upper side and a second insert post on its lower side. The top wall of the inner cavity has a first slot that mates with the first insert post, and a first elongated groove is connected to the lower side of the first slot. The bottom plate has a second slot that mates with the second insert post, and a second elongated groove is connected to the upper side of the second slot. The diaphragm can enter both the first and second elongated grooves. The bottom plate has a grid groove, and the diaphragm is located on both sides of the grid groove. The top of the box has a protruding rigid handle, and the bottom of the box has a groove that mates with the rigid handle. The inner side of the movable end of the box door has a first magnetic strip, and the front face of the box has a second magnetic strip that attracts the first magnetic strip. Buckles are located on both sides of the baffle, and slots mate with the buckles are located on the sides of the box. Both sides of the base plate are provided with condensation grooves, and the outer side of the upper opening of each condensation groove is provided with an inclined surface, which is located on the lower side of the inner cavity side wall of the box.

The spring always tends to push the lower end of the locking rod through the guide sleeve. A pull block is provided at the upper end of the locking rod that passes through the guide sleeve. A locking hole penetrating the box door is opened in the inner groove on the lower side of the guide sleeve. A locking ring is installed on the front face of the box body corresponding to the position of the locking hole. When the box door is rotated to close the box body, the locking ring can pass through the locking hole, and under the elastic force of the spring, the lower end of the locking rod enters the locking ring to achieve locking and limiting.

[0006] The positive effects of this utility model are as follows: The high-speed rail-specific temperature-sensitive cold chain food transport box described in this utility model has a horizontally pull-out bottom plate inside the box, and a rotating and opening door on the front surface of the box above the bottom plate, which facilitates the retrieval of the food containers inside when the transport boxes are stacked.

[0017] The present invention describes a high-speed rail-specific temperature-sensitive cold chain food transport box, such as... Figure 1-4 As shown, the container includes a box body 1. A sliding groove 2 is provided at the bottom of the box body 1. A pull-out bottom plate 3 is installed in the sliding groove 2. The bottom plate 3 is used to store lunch boxes. Pulling out the bottom plate 3 can quickly remove or put in lunch boxes inside the box body 1.

[0018] A baffle 4 is provided at the front end of the base plate 3. The baffle 4 is located on the outside of the box body 1 and can limit the pull-out of the base plate 3. A rotatable box door 6 is installed on the front surface of the box body 1 via a hinge 5. The box door 6 is located above the baffle 4. When the box door 6 is rotated and closed, it can keep the space inside the box body 1 closed.

[0019] A limiting groove 7 is provided at the top of the baffle 4 to cooperate with the door 6. When the door 6 is closed, the bottom plate 3 cannot be pulled out from the sliding groove 2. Only after the door 6 is opened can the bottom plate 3 be pulled out horizontally to retrieve and transfer the food containers on the top of the bottom plate 3. Traditional insulated boxes usually have a snap-on lid on the top. If multiple insulated boxes are stacked, the bottom lid is blocked and cannot be opened to retrieve the food. The food containers at the top can only be retrieved in sequence, and the insulated box with the food containers inside can be moved before the food in the bottom insulated box can be retrieved one by one. The high-speed rail special temperature-sensitive cold chain food transport box described in this utility model has the door 6 located on the front face of the box body 1. When several boxes 1 are stacked, there is no need to move the transport boxes. Each door 6 can be opened manually, which solves the problem of retrieving the food inside traditional insulated boxes when they are stacked.

[0020] To isolate the internal food containers from the ice boxes 9 and prevent cross-contamination, two sets of partitions 8 are arranged side-by-side between the bottom plate 3 and the top wall of the inner cavity of the box 1. These partitions 8 divide the inner cavity of the box 1 into three isolated spaces. Ice boxes 9 are placed between each partition 8 and the inner wall of the box 1. The three spaces are a low-temperature chamber on each side for the ice boxes 9, and a food storage chamber between the partitions 8 for the food containers. The partitions 8 and the door 6 effectively isolate the ice boxes 9 from the food containers, thus ensuring the hygiene and safety of the food during transport. Uncontaminated ice boxes 9 can be easily cleaned. Because the partitions 8 effectively prevent spillage of food waste, the ice boxes 9 on the sides can be reused for a period of time before needing regular cleaning, thereby improving overall transport efficiency.

[0021] To improve the low-temperature insulation performance inside the container 1, insulation layers 23 are provided inside the container 1, baffle 4, and door 6. A temperature display screen 34 is also installed on the door 6. A temperature sensor 35 is installed inside the cavity of the container 1, and the temperature sensor 35 is connected to the temperature display screen 34 via control circuitry. The temperature sensor 35 can detect the real-time temperature inside the container 1 and transmit the temperature data to the temperature display screen 34, allowing staff to easily observe the temperature inside the container 1 to ensure it meets the low-temperature requirements of cold chain transportation. The temperature sensor 35 and temperature display screen 34 can be existing temperature measuring devices inside refrigerators or digital displays on refrigerator doors, reflecting the internal temperature data in real time from the outside. Furthermore, the transport container described in this application can also include an automatic temperature recording function for post-incident investigation and evidence collection.

[0022] Furthermore, for cleaning or replacement of the diaphragm 8, the diaphragm 8 is detachably installed between the bottom plate 3 and the top wall of the inner cavity of the housing 1, such as... Figure 5 As shown, the diaphragm 8 is detachably installed between the bottom plate 3 and the top wall of the inner cavity of the box 1. The upper side of the diaphragm 8 is provided with a first insertion post 10, and the lower side of the diaphragm 8 is provided with a second insertion post 11. The diaphragm 8 is fixedly installed between the first insertion post 10 and the second insertion post 11.

[0023] The top wall of the inner cavity of the housing 1 is provided with a first slot 12 that mates with the first insert post 10. The lower side of the first slot 12 is provided with a first elongated groove 13 that is connected to it. The bottom plate 3 is provided with a second slot 14 that mates with the second insert post 11. The upper side of the second slot 14 is provided with a second elongated groove 15 that is connected to it. The diaphragm 8 can enter the first elongated groove 13 and the second elongated groove 15.

[0024] When installing the diaphragm 8, the base plate 3 can be pulled out from the box 1, and the second insert 11 can be inserted from the rear end of the base plate 3 into the second slot 14. After the diaphragm 8 is installed on the base plate 3, the base plate 3 and the diaphragm 8 are installed into the box 1 together, and the first insert 10 is inserted into the first slot 12 on the front end of the box 1. After installation, the diaphragms 8 on both sides can divide the internal space of the box 1 into three mutually isolated spaces. Ice boxes 9 are placed in the spaces on both sides to provide a low-temperature environment, and the middle space is used to place the transported lunch boxes. The diaphragm 8 effectively isolates the lunch boxes from the ice boxes 9.

[0025] Furthermore, such as Figure 6 As shown, the bottom plate 3 is provided with a grid groove 16, and the diaphragm 8 is located on both sides of the grid groove 16. The grid groove 16 can provide stable support for the upper lunch box, and the internal slots can temporarily store the soup spilled inside the lunch box to avoid contaminating the internal space of the box 1. When recycling the transport box, the bottom plate 3 can be pulled out for quick cleaning, which effectively improves the cleaning efficiency of recycling.

[0026] Furthermore, in order to facilitate handling and moving of the transport box, the top of the box body 1 is provided with an outwardly protruding rigid handle 17, and the bottom of the box body 1 is provided with a groove 18 that cooperates with the rigid handle 17. When multiple transport boxes are stacked, the rigid handle 17 of the box body 1 located on the lower side can be embedded into the groove 18 of the box body 1 located on the upper side, thereby increasing the stability of the transport boxes when stacked.

[0027] Furthermore, in order to ensure the airtightness of the door 6 when it is rotated and closed, a first magnetic strip 19 is provided on the inner side of the movable end of the door 6, and a second magnetic strip 20 that can be attracted to the first magnetic strip 19 is provided on the front end of the box body 1. The above design allows the door 6 to fit tightly against the box body 1 when it is rotated and closed, preventing the cold air inside from leaking out and keeping the space inside the box body 1 at a stable low temperature.

[0028] Under normal circumstances, when the door 6 is closed, the bottom plate 3 will not move out of the slide 2 due to the setting of the limiting groove 7. If the transport box is impacted and tilted, the closing suction force of the door 6 on the box body 1 is insufficient to offset the gravity component of the bottom plate 3, and the bottom plate 3 will come out of the box body 1, resulting in the spillage of the food inside. To avoid the above problem, buckles 21 are provided on both sides of the baffle 4, and the side of the box body 1 is provided with a slot 22 that cooperates with the buckles 21. After the door 6 is opened, the bottom plate 3 will still be restricted by the buckles 21 on both sides. Only after the buckles 21 are removed from the slot 22 can the bottom plate 3 be pulled out of the slide 2 and the food box on the top of the bottom plate 3 be taken out.

[0029] Furthermore, in order to effectively collect the condensate in the 9 cavities on both sides and prevent the condensate from condensing inside the box 1 and flowing around, thus affecting the transportation of food inside, such as... Figure 8 As shown, condensate troughs 24 are provided on both sides of the base plate 3, and an inclined surface 25 is provided on the outer side of the upper opening of each condensate trough 24. The inclined surface 25 is located on the lower side of the inner cavity sidewall of the box body 1. The inclined surface 25 makes it easier for condensate on the inner cavity sidewall to enter the condensate trough 24 along the wall, which facilitates the unified collection of condensate.

[0030] To further achieve a relatively stable locking and closure between the door 6 and the body 1, and to facilitate rotational separation between them, a locking mechanism is also provided between the door 6 and the body 1, such as... Figure 9 As shown, the locking mechanism includes a recessed groove 26 formed on the outer surface of the door 6. A vertically arranged guide sleeve 27 is installed in the recessed groove 26, and a locking rod 33 is installed inside the guide sleeve 27. Both the upper and lower ends of the locking rod 33 can pass through the guide sleeve 27. A limiting flange 28 is provided on the outer periphery of the locking rod 33 located inside the guide sleeve 27. A spring 29 is installed inside the guide sleeve 27 on the upper side of the limiting flange 28. The spring 29 always tends to allow the lower end of the locking rod 33 to pass through the guide sleeve 27.

[0031] A pull block 30 is provided at the upper end of the locking rod 33 that extends out of the guide sleeve 27. A locking hole 31 that penetrates the door 6 is provided in the recessed groove 26 on the lower side of the guide sleeve 27. A locking ring 32 is installed on the front end face of the box body 1 corresponding to the position of the locking hole 31. When the box body 1 is closed by rotating the door 6, the locking ring 32 can pass through the locking hole 31 and enter the locking ring 32 under the elastic force of the spring 29 to achieve locking and limiting.

[0032] The recessed groove 26 ensures that the guide sleeve 27 and locking rod 33 do not extend beyond the outer surface of the door 6, and the locking mechanism is located on one side of the inner cavity of the box body 1, so it does not affect the placement of the internal food containers. When it is necessary to open the closed door 6, the pull block 30 can be pushed upward to overcome the elastic force of the spring 29, causing the lower end of the locking rod 33 to move upward and separate from the locking ring 32. After the locking rod 33 is no longer restricted, the door 6 can be rotated and opened relative to the box body 1. Closing the door 6 is also relatively convenient. Simply push the pull block 30 upward while rotating the door 6, so that the lower end of the locking rod 33 does not block the locking hole 31. After the door 6 rotates and fits against the box body 1, the locking ring 32 can extend through the locking hole 31. Then, release the pull block 30, and under the elastic force of the spring 29, the locking rod 33 can move vertically downward and enter the locking ring 32, thereby achieving a closed lock between the door 6 and the box body 1.

[0033] This utility model discloses a temperature-sensitive cold chain food transport box for high-speed rail, which effectively solves the problems existing in the prior art through a series of innovative designs and technological improvements. This transport box not only has excellent heat preservation and hygiene safety, but also improves the efficiency of food transport and the convenience of use for staff, showing broad application prospects and significant practical value in the field of high-speed rail food transport.
