Description

Technical Field

[0001] This utility model relates to the field of insulated boxes, and in particular to an insulated box for cold chain distribution. Background Technology

[0002] Cold chain insulated boxes are specialized containers designed to meet the transportation needs of low-temperature goods. With their special materials, structure, and performance, they can effectively isolate heat exchange between the inside and outside of the box and maintain a specific temperature environment inside. They are widely used in the fields of fresh food, pharmaceuticals, and chemicals.

[0003] The outer layer is the protective layer of the insulated box, which is in direct contact with the external environment. It needs to have the characteristics of impact resistance, corrosion resistance, and water resistance. Its main function is to protect the internal structure and reduce external physical damage. The insulation layer is the key to isolating the heat exchange between the inside and outside. It is located between the outer and inner layers. It uses materials with low thermal conductivity to reduce heat conduction, heat convection and heat radiation. It is the core part that determines the insulation effect. The sealing system is used to prevent air convection between the inside and outside of the box and reduce heat exchange. It is the last line of defense to ensure the insulation effect.

[0004] To ensure airtightness, some insulated boxes use multiple sets of buckles or complex locking structures, requiring individual operation when opening and closing. This is especially time-consuming during frequent deliveries. Zippers on some soft-sided insulated boxes tend to jam after prolonged use, increasing the difficulty of opening and closing. Most hard-sided insulated boxes use a rigid outer shell and fixed structure to ensure airtightness and insulation, lacking cushioning design. When encountering bumps or impacts, external force is directly transmitted through the box to the contents, especially for fragile items, which are easily damaged by impact. Therefore, a cold chain delivery insulated box is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a cold chain delivery insulated box, which aims to improve the problems of inconvenient operation and low shock resistance in the existing technology.

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

[0007] A cold chain delivery insulated box includes an outer shell, a base plate fixedly connected inside the outer shell, four support blocks fixedly connected to the top of the base plate, a follower plate rotatably connected to one side of each of the four support blocks, a rotating shaft rotatably connected to the end of the follower plate away from the support block, a slider fixedly connected to the outside of the rotating shaft, a rotating plate rotatably connected to the outer wall of the rotating shaft, a fixed plate rotatably connected to the other end of the rotating plate, a support plate fixedly connected to the top of the four fixed plates, a pressing block fixedly connected to the bottom of the support plate, a cavity slidably connected to the outside of the pressing block, a connecting block slidably connected to the inside of the cavity, the bottom of the connecting block fixedly connected to the top of the base plate, a cover plate rotatably connected to the top of the outer shell, and a fixing assembly fixedly connected to one side of the outer shell.

[0008] As a further description of the above technical solution:

[0009] The fixing assembly includes a motor, one side of which is fixedly connected to one side of the housing. A gear is fixedly connected to the drive end of the motor. Two blocks are fixedly connected to the inner wall of the housing. A sliding column is fixedly connected to the inner wall of each of the two blocks. A sliding rod is slidably connected inside the sliding column. A washer is fixedly connected to the outer wall of the sliding rod. A lock cylinder is fixedly connected to the outer wall of the sliding rod. Two racks are fixedly connected to one side of each of the two lock cylinders. A spring is sleeved on the outer wall of each of the two sliding rods. A latch is slidably connected to the adjacent side of each of the two lock cylinders.

[0010] As a further description of the above technical solution:

[0011] The two racks are meshed with the gear, and the top of the latch is fixedly connected to the bottom of the cover plate;

[0012] As a further description of the above technical solution:

[0013] Wheels are rotatably connected to both sides of the lock cylinder, and the outer wall of the wheel is slidably connected to the inner wall of the outer casing;

[0014] As a further description of the above technical solution:

[0015] The inner wall of the cavity is slidably connected to two sliders, and the outer wall of the rotating shaft is fixedly connected to the inner wall of the sliders;

[0020] As a further description of the above technical solution:

[0021] The bottom of the pressing block is in contact with the top of the connecting block, and the bottom of the cover plate is in contact with the top of the disassembly box.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, when the support plate is delivering goods, it slides downwards due to bumps. The sliding of the support plate will drive the sliding of the support block and the fixed plate. The sliding of the fixed plate will drive the rotation of the rotating plate. The rotation of the rotating plate will squeeze the slider to slide in the cavity. The sliding of the slider will drive the cavity to slide outside the connecting block. The cavity contains air. The downward sliding of the lower block will compress the air in the cavity. When the air in the cavity is compressed to a certain extent, it will push the lower block to slide upwards, thereby achieving the shockproof effect on the delivered items in the disassembly box.

[0024] 2. In this utility model, the rotation of the cover plate drives the rotation of the latch, and the rotation of the latch drives the sliding of the lock cylinder. When the latch slides to the bottom, the lock cylinder slides under the action of the spring, thereby realizing the locking process of the box. At this time, the cover plate is tightly connected to the outer shell, without losing the heat preservation function of the delivered items. When the box is opened during delivery, the rotation of the gear is controlled by the motor, and the rotation of the gear drives the sliding of the rack, which in turn drives the sliding of the lock cylinder. At this time, the latch is opened, thus realizing the convenience of the delivery process. Attached Figure Description

[0032] 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.

[0033] Reference Figure 1 , Figure 4 and Figure 5 This utility model provides an embodiment of a cold chain delivery insulated box, including an outer shell 1. The outer shell 1 serves as the main structure of the insulated box, providing basic protection and insulation for internal components and delivered goods. A base plate 2 is fixedly connected inside the outer shell 1. The base plate 2 provides a stable installation foundation for various support components inside the insulated box, enhancing the overall structural stability. Four support blocks 3 are fixedly connected to the top of the base plate 2. A follower plate 4 is rotatably connected to one side of each of the four support blocks 3. The four support blocks 3 provide reliable rotation support points for the follower plate 4, ensuring the stability of the follower plate 4 during rotation. The follower plate 4 can flexibly rotate with the force generated by external bumps, transmitting the force to subsequent components and providing a power transmission path for the shock absorption function.

[0034] The end of the follower plate 4 away from the support block 3 is rotatably connected to the rotating shaft 14 to realize the transmission and conversion of force. The outside of the rotating shaft 14 is fixedly connected to the slider 11 to provide assistance for the generation of buffer force. The outer wall of the rotating shaft 14 is rotatably connected to the rotating plate 5, which can transmit the movement of the rotating shaft 14. The other end of the rotating plate 5 is rotatably connected to the fixed plate 6, which can transmit the force transmitted from the rotating plate 5 to the top. The top of the four fixed plates 6 is fixedly connected to the support plate 7, which is an important intermediate component for force transmission. The bottom of the support plate 7 is fixedly connected to the pressure block 8, which can generate buffer force through changes in air pressure.

[0035] The inner wall of the outer shell 1 is slidably connected to a disassembly box 24, which can hold delivery items. When bumpy, the disassembly box 24 slides to transmit the force generated by the shaking to the support plate 7, triggering the shock-absorbing mechanism. The top of the support plate 7 and the bottom of the disassembly box 24 are in contact. This contact method ensures that the pressure generated by the disassembly box 24 can be effectively transmitted to the support plate 7, ensuring the normal triggering and operation of the shock-absorbing mechanism. The lower pressure block 8 is slidably connected to a cavity 9. The cavity 9 provides sliding space for the lower pressure block 8. When the air inside is compressed, it can generate a reverse force, providing the core power for the buffer function.

[0036] The cavity 9 is internally connected to a sliding link block 10, which provides guidance for the sliding of the cavity 9, ensuring the stability of the cavity 9 during the sliding process and ensuring the orderly progress of the air compression process. The inner wall of the cavity 9 is slidably connected to two sliders 11. When the two sliders 11 slide inside the cavity 9, they can drive the cavity 9 to move synchronously, enhancing the compression effect on the air inside the cavity 9 and improving the buffering performance. The outer wall of the rotating shaft 14 is fixedly connected to the inner wall of the slider 11. This fixed connection method ensures that the movement of the rotating shaft 14 can be synchronously transmitted to the slider 11, so that the slider 11 can slide smoothly.

[0037] The bottom of the connecting block 10 is fixedly connected to the top of the base plate 2. The connecting block 10 provides stable support for itself through the fixed connection with the base plate 2, ensuring the overall stability of the buffer mechanism. The top of the outer shell 1 is rotatably connected to the cover plate 23. The cover plate 23 can be rotated to open and close the insulated box, which is convenient for taking and putting in items during delivery. A fixing component is fixedly connected to one side of the outer shell 1. The fixing component can lock and open the cover plate 23 and the outer shell 1, ensuring the sealing of the insulated box and the ease of operation.

[0038] Reference Figures 1 to 3 The fixing component includes a motor 21, which provides power for opening the fixing component. The motor 21 drives the gear 20 to rotate, thereby enabling the lock cylinder 16 to slide and improving the convenience of the opening process. One side of the motor 21 is fixedly connected to one side of the outer shell 1. This fixing method ensures the stability of the motor 21 during operation and avoids the impact of vibration on the power output. The drive end of the motor 21 is fixedly connected to the gear 20, which can transmit the rotational power of the motor 21, realizing the conversion and transmission of power. Two blocks 12 are fixedly connected to the inner wall of the outer shell 1. The two blocks 12 provide a certain support force. The inner walls of the two blocks 12 are fixedly connected to the sliding column 13. The sliding column 13 provides a sliding track for the sliding rod 15, restricting the movement direction of the sliding rod 15 and enabling the sliding rod 15 to slide stably.

[0039] The bottom of the base plate 2 is in contact with the inner wall of the outer shell 1. This contact method enhances the connection stability between the base plate 2 and the outer shell 1 and improves the overall structural strength of the insulation box. The cross-sectional shape of the stop block 12 is L-shaped. The L-shaped structure can better fix the sliding column 13 and at the same time play a certain limiting role for the sliding parts, ensuring the orderly movement of the parts. The sliding column 13 is slidably connected to the sliding rod 15. The sliding rod 15 can slide inside the sliding column 13 and is a key component of the internal structure. The outer wall of the sliding rod 15 is fixedly connected to the gasket 25. The gasket 25 can enhance the fit between the sliding rod 15 and related parts and prevent excessive rebound. The outer wall of the sliding rod 15 is fixedly connected to the lock cylinder 16. The lock cylinder 16 is a key component for opening and closing the insulation box.

[0040] Two racks 19 are fixedly connected to one side of each of the two lock cylinders 16. The racks 19 mesh with gears 20, which can convert the rotational motion of the gears 20 into their own linear sliding motion, thereby driving the lock cylinders 16 to slide. Both sides of the lock cylinders 16 are rotatably connected to wheels 18. The wheels 18 can reduce the friction between the lock cylinders 16 and the inner wall of the outer shell 1 when sliding, making the sliding of the lock cylinders 16 smoother and reducing operating resistance. The outer wall of the wheel 18 is slidably connected to the inner wall of the outer shell 1. The sliding contact between the wheel 18 and the inner wall of the outer shell 1 provides guidance and support for the sliding of the lock cylinders 16, ensuring the stability of the movement of the lock cylinders 16.

[0041] Springs 17 are fitted on the outer walls of both sliding rods 15. When the latch 22 slides to the bottom, the springs 17 provide elastic force to push the lock cylinder 16 to slide, thereby achieving automatic locking of the insulated box. The latch 22 is slidably connected to the side of the two lock cylinders 16 that are close to each other. The latch 22 can drive the lock cylinder 16 to slide as the cover plate 23 rotates, and finally cooperates with the lock cylinder 16 to lock the insulated box. The two racks 19 are meshed with the gear 20. This meshing connection ensures that the rotation of the gear 20 can be accurately transmitted to the rack 19, ensuring the reliability and accuracy of the sliding of the lock cylinder 16.

[0042] The top of the latch 22 is fixedly connected to the bottom of the cover plate 23. The latch 22 rotates synchronously with the rotation of the cover plate 23, thereby driving the lock cylinder 16 to complete the locking action and fixing the cover plate 23 to the outer shell 1. The bottom of the lower pressure block 8 and the top of the connecting block 10 are in contact. This contact method provides a certain support for the lower pressure block 8 during the buffering process, ensuring the stability of the lower pressure block 8 when sliding up and down and ensuring the buffering effect. The bottom of the cover plate 23 is in contact with the top of the disassembly box 24. This contact enhances the sealing performance when the cover plate 23 and the outer shell 1 are closed, reduces the heat loss inside the box, and improves the heat preservation effect.

[0043] Working principle: When encountering bumpy roads during delivery, the delivered items in the disassembly box 24 will shake to some extent. At this time, the disassembly box 24 will generate downward pressure, causing the support plate 7 to slide downward. The sliding of the support plate 7 will cause the lower pressure block 8 and the fixed plate 6 to slide. The sliding of the fixed plate 6 will cause the rotating plate 5 to rotate. The rotation of the rotating plate 5 will squeeze the slider 11 to slide inside the cavity 9. The sliding of the slider 11 will cause the cavity 9 to slide outside the connecting block. The cavity 9 contains air. The downward sliding of the lower pressure block 8 will compress the air in the cavity 9. When the air in the cavity 9 is compressed to a certain extent, it will push the lower pressure block 8 to slide upward, thereby achieving the shockproof effect on the delivered items in the disassembly box 24.

[0044] During delivery, the lid needs to be opened and closed repeatedly. To close the box, simply rotate the cover plate 23. The rotation of the cover plate 23 drives the lock 22 to rotate, which in turn drives the lock cylinder 16 to slide. When the lock 22 slides to the bottom, the lock cylinder 16 slides under the action of the spring 17, thus locking the box. At this time, the cover plate 23 is tightly connected to the outer shell 1, maintaining the insulation effect on the delivered items. When the box is opened during delivery, the motor 21 controls the rotation of the gear 20. The rotation of the gear 20 drives the rack 19 to slide, which in turn drives the lock cylinder 16 to slide. At this time, the lock 22 is opened, thus achieving convenience during the delivery process.

[0045] 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.
