Description

Technical Field

[0001] This utility model relates to the field of cold chain transport box technology, and in particular to a temperature-controlled protective box for cold chain transport. Background Technology

[0002] Cold chain transport protective boxes are sealed transport containers designed specifically for low-temperature sensitive goods (such as fresh produce, medicines, vaccines, biological samples, etc.). Their core function is to maintain a specific temperature range inside the box throughout the entire transportation process, isolate external environmental temperature fluctuations, and protect the goods inside the box.

[0003] For example, the temperature-controlled box for cold chain transportation with protective function disclosed in patent number CN221341685U detects the temperature inside the box through temperature sensors. When cooling is required, the refrigeration unit 6 can be activated. However, the box wall of this transport box is an integrated non-removable structure, and the interior is filled with a single insulation material. The insulation layer and the corresponding temperature zone function are fixed during production and cannot be flexibly adjusted according to the needs of the goods. Moreover, temperature control relies on electricity and the control system, which is not conducive to energy conservation and environmental protection. Utility Model Content

[0004] The purpose of this invention is to provide a temperature-controlled protective box for cold chain transportation, which solves the problem that the insulation layer inside existing cold chain transportation boxes is difficult to replace.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a temperature-controlled protective box for cold chain transportation, including a protective box body; An insulation module is provided at the edge of the interior of the protective box body. The insulation module is equipped with a replacement mechanism. The replacement mechanism includes a rim at the top edge of the insulation module. Each of the four corners at the bottom of the rim is equipped with an insert block. Each of the four corners at the top of the protective box body is provided with a slot that matches the insert block. Each insert block is equipped with a pressure plate evenly arranged inside by a return spring. Each pressure plate has a retaining bead at one end. Each slot on the protective box body away from the retaining bead has a retaining hole. The protective box has clamping plates on both sides inside the main body, and buffers are evenly distributed on one side of the clamping plates.

[0006] Preferably, a cold source chamber is provided at the bottom of the protective box body, and the top of the cold source chamber is uniformly provided with through holes, and the top of the cold source chamber is uniformly connected to the bottom of the protective box body through the through holes.

[0007] The above structure allows the cold energy generated by the cold source in the cold source chamber to enter the main body of the protective box evenly, providing sufficient cold energy support to maintain a stable low-temperature environment for the goods inside the box.

[0008] Preferably, a bidirectional lead screw is provided on one side of the bottom of the protective box body via a bracket, and both ends of the bidirectional lead screw are fitted with movable sleeves. One side of each movable sleeve is connected to a clamping plate. A handle is provided on the outside of the protective box body at one end of the bidirectional lead screw, and the handle is connected to the bidirectional lead screw via a connecting shaft.

[0009] With the above structure, turning the handle can drive the bidirectional lead screw to move the clamping plate closer or further away in sync, so as to achieve convenient clamping and releasing of goods of different sizes.

[0010] Preferably, a guide rod is provided on the bottom of the protective box body away from the bidirectional lead screw, and guide sleeves are fitted on both ends of the guide rod. The guide sleeves are connected to the side of the clamping plate away from the movable sleeve.

[0011] The above structure provides stable guidance for the movement of the clamping plate, preventing it from shifting or tilting during the clamping process and ensuring clamping stability.

[0012] Preferably, the insulation module is provided with positioning strips on all four sides, and the protective box body is provided with positioning grooves that match the positioning strips on all four sides.

[0013] The above structure allows for quick positioning of the insulation module during installation, preventing misalignment from affecting the insulation effect and improving the efficiency of insulation module installation and removal.

[0014] Preferably, the bottom surface of the surrounding edge is uniformly provided with sealing strips, and the top surface of the protective box body is uniformly provided with sealing grooves that match the sealing strips. The sealing strips are all made of silicone.

[0015] The above structure enhances the sealing of the connection between the insulation module and the main body of the protective box, effectively reduces heat exchange between the inside and outside of the box, reduces cold loss, and strengthens the insulation effect.

[0016] Preferably, all the buffer components are semi-circular structures and are hollow rubber structures.

[0017] The above structure utilizes the high elasticity of rubber and the hollow design to absorb the impact force during transportation, preventing the goods from being squeezed and damaged when clamped.

[0018] The present invention provides a temperature-controlled protective box for cold chain transportation, the advantages of which are: The system comprises a protective box body, an insulation module, and a replacement mechanism. The replacement mechanism includes positioning strips, positioning grooves, a surrounding edge, insert blocks, slots, return springs, pressure plates, locking beads, and locking holes. When the insulation module is inserted into the protective box body, the positioning strips are first inserted into the corresponding positioning grooves. After full insertion, the insert blocks around the bottom of the surrounding edge are embedded into the slots at the four corners of the top surface of the protective box body. Pressure plates are evenly distributed inside the insert blocks via return springs, and locking beads are located at one end of each pressure plate. Locking holes are also provided on one side of the protective box body near the slots. The locking beads... When passing through the locking hole, the module pops out of the locking hole under the action of the return spring, thus fixing the insulation module inside the protective box body. During disassembly, by pressing the locking ball inward, the pressure plate presses the return spring, and the locking ball is stored inside the insertion block. Then, the insulation module can be pulled out upward for replacement. The insulation module is filled with differentiated materials, eliminating the need to purchase multiple sets of protective box bodies for goods in different temperature zones. Only the internal insulation module needs to be replaced, allowing the same box to switch between different temperature zones such as freezing, refrigeration, and cool. Moreover, no electricity or control equipment is required, which is beneficial for energy conservation and emission reduction.

[0019] Equipped with a bidirectional lead screw, movable sleeves, a handle, a clamping plate, and buffer components, the goods to be transported are placed inside the protective box. By turning the handle, the bidirectional lead screw is rotated, causing the movable sleeves to move closer together along the lead screw. The clamping plate then clamps and secures the goods on both sides, preventing collisions between the goods and the inner wall of the protective box during transport. Buffer components, made of semi-circular hollow rubber, are evenly distributed on one side of the clamping plate. These components are highly elastic and deform under external pressure, converting hard impact force into elastic deformation force. This prevents the goods from directly colliding with the hard clamping plate, thus limiting the movement of the goods while increasing their protection. Attached Figure Description

[0022] 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.

[0023] Please see Figure 1-5 The present invention provides a temperature-controlled protective box for cold chain transportation, comprising a protective box body 1; Please see Figure 1 The bottom of the protective box body 1 is provided with a cold source chamber 2, and the top of the cold source chamber 2 is evenly provided with through holes 11. The top of the cold source chamber 2 is evenly connected to the bottom of the protective box body 1 through the through holes 11. The inner edge of the protective box body 1 is provided with a heat insulation module 4. Based on the target temperature zone required for the goods to be transported, such as freezing, refrigeration, or cooling, select the insulation module 4 with the corresponding differentiated insulation material inside. High vacuum insulation board is used for freezing, aerogel felt is used for refrigeration, and perlite composite board is used for cooling goods. At the same time, prepare cold sources suitable for the temperature zone, such as ice plates and dry ice, and put them into the cold source chamber 2 at the bottom of the protective box body 1. The cold energy generated by the cold source enters the interior of the protective box body 1 through the through hole 11 opened at the top of the cold source chamber 2 to pre-cool the inside of the box. Please see Figures 1-4 The insulation module 4 is provided with a replacement mechanism 3, and the replacement mechanism 3 includes a perimeter 302 located at the top edge of the insulation module 4. Each of the four corners at the bottom of the perimeter 302 is provided with a plug 301. Each of the four corners at the top of the protective box body 1 is provided with a slot 305 that matches the plug 301. The inside of the plug 301 is provided with a pressure plate 309 evenly through a reset spring 308. Each end of the pressure plate 309 is provided with a locking bead 307. Each side of the slot 305 away from the locking bead 307 is provided with a locking hole 306. Each of the four sides of the insulation module 4 is provided with a positioning strip 303. Each of the four sides inside the protective box body 1 is provided with a positioning groove 304 that matches the positioning strip 303. Next, the selected insulation module 4 is aligned with the inside of the protective box body 1, so that the positioning strips 303 around the insulation module 4 are inserted into the positioning grooves 304 opened around the inside of the protective box body 1, thus achieving the initial positioning of the insulation module 4. Then, the insulation module 4 is fully inserted into the protective box body 1. At this time, the insert blocks 301 at the bottom of the four corners of the top edge 302 of the insulation module 4 are embedded into the slots 305 at the top four corners of the protective box body 1. The pressure plate 309 connected inside the insert block 301 by the reset spring 308 moves synchronously with the insertion of the insert block 301. When the retaining bead 307 at one end of the pressure plate 309 moves to the position of the retaining hole 306 on the protective box body 1 on the side of the slot 305, the reset spring 308 releases its elastic force to push the pressure plate 309, so that the retaining bead 307 pops out to the outside of the retaining hole 306, thus fixing the insulation module 4 inside the protective box body 1. The bottom surface of the edging 302 is uniformly provided with sealing strips 6, and the top surface of the protective box body 1 is uniformly provided with sealing grooves 5 that match the sealing strips 6. The sealing strips 6 are all made of silicone. The silicone sealing strips 6 on the bottom surface of the edging 302 are embedded in the sealing grooves 5 on the top surface of the protective box body 1 to enhance the sealing performance at the connection between the insulation module 4 and the protective box body 1. Please see Figure 5 The protective box body 1 has clamping plates 9 on both sides inside, and buffers 10 are evenly distributed on one side of the clamping plates 9. The bottom of the protective box body 1 has a double screw rod 7 installed on one side through a bracket, and movable sleeves 8 are fitted on both ends of the double screw rod 7. One side of the movable sleeves 8 is connected to the clamping plates 9. A handle 14 is installed on the outside of the protective box body 1 at one end of the double screw rod 7, and the handle 14 is connected to the double screw rod 7 through a connecting shaft. The buffers 10 are all semi-circular structures and are all hollow rubber structures. Place the goods to be transported into the insulation module 4 enclosed area inside the protective box body 1. Rotate the handle 14 on the outside of one end of the bidirectional screw 7 on the bottom side bracket of the protective box body 1. The handle 14 drives the bidirectional screw 7 to rotate through the connecting shaft. The movable sleeves 8 at both ends of the bidirectional screw 7 move closer to each other along the thread direction of the bidirectional screw 7. The movable sleeves 8 drive the clamping plates 9 connected to them to move synchronously until the semi-circular hollow rubber buffer 10 on both sides of the clamping plates 9 are in close contact with the sides of the goods. The elastic deformation of the buffer 10 clamps and fixes the goods, preventing the goods from shaking inside the box. A guide rod 12 is provided on the side of the bottom of the protective box body 1 away from the bidirectional lead screw 7, and guide sleeves 13 are sleeved on both ends of the guide rod 12. The guide sleeves 13 are connected to the side of the clamping plate 9 away from the movable sleeve 8. When the clamping plate 9 moves, the guide sleeves 13 slide along the guide rod 12 to ensure that the clamping plate 9 moves smoothly. During transportation, the insulation module 4 blocks the heat exchange between the inside and outside of the box through the internal differentiated insulation material. In conjunction with the cold source in the cold source chamber 2, the cold energy is continuously supplied through the through hole 11 to maintain a stable target temperature zone inside the protective box body 1. At the same time, the buffer 10 on the clamping plates 9 on both sides of the cargo transforms the hard impact force generated by transportation bumps into elastic deformation force through its own high elasticity and hollow structure, so as to avoid the cargo being damaged by direct impact with the clamping plates 9. After transportation is completed, the handle 14 is rotated in the opposite direction to drive the bidirectional lead screw 7 to rotate, causing the movable sleeve 8 to move away from the clamping plates 9, releasing the clamping of the goods and removing the goods. If it is necessary to replace the insulation module 4 to adapt to goods in other temperature zones, press the locking bead 307 on the outside of the locking hole 306 to make the locking bead 307 squeeze the pressure plate 309 and compress the return spring 308 until the locking bead 307 is stored inside the insert block 301. At this time, pull the insulation module 4 upward to make the insert block 301 disengage from the slot 305 and the positioning strip 303 disengage from the positioning groove 304, completing the disassembly of the old insulation module 4. Then, install the new insulation module 4 adapted to the temperature zone. There is no need to purchase multiple protective box bodies 1 for goods in different temperature zones. Only the internal insulation module 4 needs to be replaced to allow the same box to switch between different temperature zones such as freezing, refrigeration, and cool. Moreover, temperature control does not require the use of electricity and control equipment, which is conducive to energy conservation and emission reduction.
