[0031] 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.
[0032] Reference Figure 3 , Figure 4 and Figure 5 This utility model provides an embodiment of a rapid sealing structure for a cold chain insulated box in a supply chain, comprising a box body 1 and an annular block 4. The box body 1 is the load-bearing structure of the device. The annular block 4 is used to guide gas. A hollow rubber ring 3 is fixedly connected to the top of the inner wall of the box body 1. The inner wall of the hollow rubber ring 3 is filled with glycerin. Glycerin has a small volume change due to temperature changes at room temperature and low temperature. A groove 5 is provided at the bottom of the annular block 4. The groove 5 is a trapezoidal groove that engages with the hollow rubber ring 3. Multiple air slots 6 are provided at the top of the annular block 4. The air slots 6 allow gas to pass through. The inner wall of the groove 5 is connected to the multiple air slots 6. An air chamber plate 7 is slidably connected to the inner wall of the annular block 4. The air chamber plate 7 slides on the inner wall of the annular block 4, thereby forming a compartment composed of the top cover 12, the annular block 4, and the air chamber plate 7. Air is exhausted and drawn in from the air trough 6. The top of the air chamber plate 7 is fixedly connected to the bottom block 8. The movement of the bottom block 8 drives the movement of the air chamber plate 7. The inner wall of the bottom block 8 is slidably connected to the upper block 9. The upper block 9 and the bottom block 8 form a telescopic column. The inner wall of the upper block 9 is threadedly connected to the spiral rod 10. The rotation of the spiral rod 10 controls the extension and retraction of the upper block 9 and the bottom block 8. The top of the spiral rod 10 is fixedly connected to the rotating wheel 11, which facilitates the rotation of the spiral rod 10. The outer wall of the annular block 4 is fixedly connected to the top cover 12. The top cover 12 is the outer cover of the entire cover and forms a sealed chamber with the annular block 4 and the air chamber plate 7. The top of the outer wall of the upper block 9 is fixedly connected to the top of the inner wall of the top cover 12. The inner wall of the box 1 is provided with a telescopic mechanism 2. The telescopic mechanism 2 is used to adjust the internal space of the box 1 for easy handling.
[0033] Specifically, when the device is closed, the hollow rubber ring 3 engages with the annular block 4. The rotating wheel 11 drives the spiral rod 10, which opens the telescopic rod composed of the upper block 9 and the bottom block 8, thereby causing the air chamber plate 7 to move downward. Because the hollow rubber ring 3 engages with the groove 5, the compartment composed of the top cover 12, the air chamber plate 7, and the annular block 4 is sealed. When the air chamber plate 7 moves downward, the air pressure inside the compartment decreases. The air groove 6 connects with the groove 5, causing the hollow rubber ring 3 to deform within the groove 5 due to pressure, thereby engaging more tightly with the groove 5 and achieving a sealing effect.
[0034] Reference Figure 4 , Figure 5 and Figure 6 The telescopic mechanism 2 includes two locking guide rails 201. Each locking guide rail 201 is a guide rail with a locking groove. The two locking guide rails 201 are fixedly connected to the front and rear sides of the inner wall of the housing 1, respectively. A return spring 202 is fixedly connected to the bottom of the inner wall of the housing 1. The return spring 202 is used to provide the lifting force of the base plate 203. The other end of the return spring 202 is fixedly connected to the base plate 203. The base plate 203 and the outer shell 206 form a box for transmitting the elastic force of the return spring 202. Rotating triangular blocks 20 are rotatably connected to the front and rear sides of the top of the base plate 203. 4. The rotating triangular block 204 is a triangular block. The bottom inner side of both rotating triangular blocks 204 is fixedly connected with a second return spring 207. The second return spring 207 is used to reset the rotating triangular block 204. The outer wall of the base plate 203 is fixedly connected with a shell 206. The front and rear sides of the shell 206 are provided with slots to facilitate the rotation of the rotating triangular block 204. The bottom inner wall of the shell 206 is slidably connected with a pressing block 205. The pressing block 205 presses the rotating triangular block 204 so that the outer side of the rotating triangular block 204 is no longer engaged with the slot of the block guide rail 201, thereby raising the entire device.
[0035] Specifically, when there is too much space inside the box 1 and it is necessary to reduce space and raise the bottom to reduce the shaking of items placed inside the box 1 and make them easier to retrieve, the pressing block 205 is pressed. The pressing block 205 drives the rotating triangular block 204 to rotate, so that the outer side of the rotating triangular block 204 is no longer engaged with the slot on the locking guide rail 201. Under the action of the first return spring 202, the bottom plate 203 gradually rises. When it is raised to the required height, the pressing block 205 is released. The rotating triangular block 204 is reset under the action of the second return spring 207 and engages with the slot on the locking guide rail 201, so that the bottom plate 203 stops rising, thereby achieving the effect of reducing space and making it easier to retrieve items.
[0036] Reference Figure 2 , Figure 5 and Figure 6An anti-accidental contact cover 13 is provided on the upper middle part of the outer casing 206. The bottom of the anti-accidental contact cover 13 is engaged with the outer casing 206. The anti-accidental contact cover 13 is used to protect the pressing block 205 and prevent it from being accidentally touched. The left and right sides of the outer wall of the box 1 are rotatably connected to the handle block 15. When the device needs to be moved, the handle block 15 rotates outward and the top of the handle block 15 engages with the box 1, thereby moving the handle block 15 to move the box 1. A thermometer 14 is fixedly connected to the rear side of the box 1. The thermometer 14 is used to display the temperature inside the device. A ring light 16 is fixedly connected to the top of the inner wall of the box 1. The ring light 16 is a ring-shaped LED light. A telescopic switch 17 is fixedly connected to the upper middle part of the box 1. The telescopic switch 17 is electrically connected to the ring light 16. When the telescopic switch 17 is pressed in contact with the top cover 12, the ring light 16 does not operate. When the top cover 12 is not in contact with the telescopic switch 17, the ring light 16 operates and lights up.
[0037] Specifically, the anti-accidental contact cover 13 protects the pressing block 205 to prevent accidental contact of the pressing block 205 during the handling process. When the telescopic mechanism 2 needs to be used, remove the anti-accidental contact cover 13 and press the pressing block 205. When handling the box 1, turn the handle block 15 outward, and the top engages with the slot on the outer wall of the box 1. Then, transport the box 1 through the handle block 15. When the lid is opened and the environment inside the box 1 is too dark, the top cover 12 does not contact the telescopic switch 17, and the ring light 16 illuminates. When the lid is closed, the top cover 12 contacts the telescopic switch 17, the ring light 16 does not illuminate, and the temperature sensor 14 displays the temperature inside the device, which facilitates real-time monitoring of the temperature inside the box.
[0038] Reference Figure 1 , Figure 3 and Figure 5 A rubber sheet 18 is fixedly connected to the top of the inner wall of the box 1. The rubber sheet 18 extends out and guides the movement of the box 1. Multiple protruding blocks 19 are fixedly connected to the top of the outer wall of the rubber sheet 18. The three protruding blocks 19, the rubber sheet 18, and the annular block 4 form two air chambers for auxiliary sealing. Support frames 20 are rotatably connected to the left and right sides of the bottom of the box 1. Frame grooves 21 are provided on the left and right sides of the bottom of the box 1. Frame grooves 21 are engaged with support frames 20. The size of support frames 20 is the same as that of frame grooves 21. Support frames 20 can be rotated to be stored in frame grooves 21. When it is necessary to move away from the contact surface, the support frames 20 are rotated to raise the height of the box 1 to prevent the box 1 from contacting the contact surface. When the support frames 20 are not needed, they are rotated to be stored in frame grooves 21. Guide columns 22 are fixedly connected to the top of the box 1 around the perimeter. Guide columns 22 are used to guide the box 1. Guide grooves 23 are provided on the bottom of the top cover 12 around the perimeter. Guide columns 22 are engaged with guide grooves 23 to prevent the cover from moving in the horizontal direction.
[0039] Working principle: Before using the device, the lid is engaged with the box body 1. At this time, the hollow rubber ring 3 is initially engaged with the groove 5. Then, the rotating wheel 11 is rotated to drive the screw rod 10 to rotate, causing the bottom block 8 and the top block 9 to expand. This causes the air chamber plate 7, which is fixedly connected to the bottom block 8, to move downward. Because the hollow rubber ring 3 is engaged with the groove 5, air cannot enter the air chamber plate 7 from the air groove 6. The air chamber plate 7, the annular block 4, and the top cover 12 form the chamber. Therefore, when the air chamber plate 7 moves, the pressure inside the chamber will decrease. This causes the hollow rubber ring 3 to be subjected to suction and deform, engaging more tightly with the groove 5, thereby achieving a sealing effect.
[0040] Furthermore, when the device needs to retract or reduce the space inside the box 1 via the telescopic mechanism 2, pressing the pressing block 205 causes the rotating triangular block 204 to rotate, thereby preventing the outer side of the rotating triangular block 204 from engaging with the slot of the locking guide rail 201. This allows the box, consisting of the base plate 203 and the outer shell 206, to move upward under the elastic force of the return spring 1 202. When it reaches a suitable height, pressing the pressing block 205 is released, and the rotating triangular block 204 returns to its original position under the action of the return spring 207, engaging with the slot of the locking guide rail 201 on its outer side. When the bottom plate 203 stops rising, placing a heavy object on the outer shell 206 or pressing the outer shell 206 will cause the outer shell 206 to pull the bottom plate 203 downward. Under the upward reaction force of the slot in the locking guide rail 201, the rotating triangular block 204 rotates inward from the outside, thereby causing the outer shell 206 to move downward until the elastic force and the downward force are balanced and no longer slide. Under the action of the return spring 207, the pressing block 205 resets and engages with the slot on the locking guide rail 201, so that the outer shell 206 will not rise due to the elastic force, thereby achieving the effect of freely controlling the capacity of the box 1 and making it easy to take out.
[0041] 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.
