DETAILED DESCRIPTION

[0024] The following will combine the drawings in the utility model to clearly and completely describe the technical solution in the utility model. In addition, the forms of the various structures recorded in the following embodiments are merely examples. The assembled pearl cotton packaging sleeve involved in the utility model is not limited to the various structures recorded in the following embodiments. All other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0025] The utility model provides an assembled pearl cotton packaging sleeve, comprising a plastic shell 1, an inner liner component 2 installed inside the plastic shell 1, a closing cover 3 rotatably installed on the top of the plastic shell 1, and a positioning component 4 installed on the closing cover 3.

[0026] The liner assembly 2 includes a pearl cotton liner 21, and a thermally conductive silicone ring 22 is provided on the outside of the pearl cotton liner 21. A spiral groove in a ring-shaped groove structure is provided on the thermally conductive silicone ring 22, and a heating wire 23 is provided in the spiral groove. An asbestos board 24 is provided on the outside of the thermally conductive silicone ring 22. The thermally conductive silicone ring 22 has good thermal conductivity, and the asbestos board 24 has good thermal insulation effect. The asbestos board 24 can prevent the heat of the heating wire 23 from being transferred to the plastic shell 1.

[0027] The positioning assembly 4 includes a connecting hole 41 , which is opened on the closing cover 3 . A moving plate 42 and a guide column 43 are provided in the connecting hole 41 . The moving plate 42 is sleeved on the surface of the guide column 43 , and a hook 44 is fixedly connected to one side of the moving plate 42 .

[0028] Furthermore, a temperature sensor 25 and a control module 26 are fixedly installed at the bottom of the inner cavity of the pearl cotton liner 21. The temperature sensor 25 and the control module 26 are electrically connected, and the control module 26 and the heating wire 23 are electrically connected. The temperature sensor 25 can monitor the temperature inside the pearl cotton liner 21 in real time, and the monitored information is transmitted to the control module 26 in the form of an electrical signal. The control module 26 analyzes the electrical signal and sends corresponding instructions to the heating wire 23 to control its opening and closing.

[0029] Furthermore, penetration holes 28 are provided at the four corners of the pearl cotton liner 21, and thread grooves 13 are provided at the four corners of the bottom of the inner cavity of the plastic shell 1. A bolt 27 is provided between the penetration hole 28 and the thread groove 13. One end of the bolt 27 is provided with an external thread, and the thread groove 13 is provided with an internal thread. The external thread matches the internal thread. One end of the bolt 27 passes through the penetration hole 28 and is screwed into the thread groove 13, so that the pearl cotton liner 21 and the plastic shell 1 can be fixed, completing the assembly between the two.

[0030] Furthermore, multiple guide posts 43 are provided, and both ends of the guide posts 43 are fixedly connected to the wall of the connecting hole 41. The moving plate 42 and the guide posts 43 form a sliding guide cooperation along the axial direction of the guide posts 43. A toggle ring 46 is fixedly connected to the connecting hole 41, and a compression spring 45 is sleeved on the surface of the guide post 43. One end of the compression spring 45 is fixedly connected to the wall of the connecting hole 41, and the other end of the compression spring 45 is fixedly connected to the side of the moving plate 42 away from the hook 44. An extension groove 11 is provided on the top of the plastic shell 1, and a docking hole 12 is provided through the wall of the extension groove 11. The docking hole 12 matches the hook 44. The elastic force of the compression spring 45 can drive the hook 44 into the docking hole 12. The hook 44 and the docking hole 12 cooperate with each other to fix the position of the closing cover 3. The staff only needs to manually depress the toggle ring 46 to pull the hook 44 out of the docking hole 12, thereby releasing the fixation. The operation is simple and convenient.

[0031] Furthermore, the closing cover 3 is fixedly connected to the pearl cotton board 31, the rear side of the plastic shell 1 is fixedly connected to the extension block 14, two extension blocks 14 are symmetrically arranged, and the extension block 14 is fixedly connected to the rotating shaft 15. The closing cover 3 is also fixedly connected to an L-shaped block 32, two L-shaped blocks 32 are symmetrically arranged, and the L-shaped block 32 is rotatably mounted on the surface of the rotating shaft 15. The closing cover 3 and the L-shaped block 32 can be rotated around the axis of the rotating shaft 15 as a whole. When the closing cover 3 is closed, the pearl cotton board 31 is inserted to the top of the pearl cotton liner 21.

[0032] The working principle of the present utility model is as follows: during actual work, the user puts the items into the pearl cotton liner 21 for safekeeping, and the user manually depresses the toggle ring 46 to make the moving plate 42 slide along the guide column 43. The compression spring 45 contracts under the extrusion of the moving plate 42, and the elastic force of the compression spring 45 increases, the moving plate 42 moves and drives the hook 44 to move synchronously. The user then pushes the closing cover 3 to rotate around the axis of the rotating shaft 15. When the hook 44 enters the extension groove 11, the toggle ring 46 is released, and the elastic force of the compression spring 45 drives the hook 44 to pass through the docking hole 12. The hook 44 and the docking hole 12 cooperate with each other to fix the position of the closing cover 3. At this time, the pearl cotton board 31 is inserted into the top of the pearl cotton liner 21, and the pearl cotton liner 21 and the pearl cotton board 31 surround the items for protection.

[0033] During the storage process, the temperature sensor 25 monitors the temperature inside the pearl cotton liner 21 in real time. When low temperature weather comes, the temperature sensor 25 detects the information and transmits it to the control module 26 in the form of an electrical signal. After analyzing the electrical signal, the control module 26 finds that the temperature is lower than the standard value. The control module 26 sends an instruction to the heating wire 23 to control the heating wire 23 to turn on. The heat of the heating wire 23 is transferred to the pearl cotton liner 21 through the thermal conductive silicone ring 22 to prevent the pearl cotton liner 21 from deformation and deterioration due to low temperature.
