[0050] Please also read Figure 1 and Figure 2 The present application provides a packaging structure 100 for packaging an item 200 to be packaged, and the item 200 to be packaged may be a disinfectant making machine, a small vertical fan, a thermos cup, etc. The packaging structure 100 is coated on the outside of the item 200 to be packaged and is used to protect the item 200 to be packaged to prevent the item 200 to be packaged from being damaged during stacking, transportation or handling.

[0051] Please also read Figure 3 , Figure 4 and Figure 5 The packaging structure 100 includes a shell 10 and a first stopper 20. The shell 10 includes a first shell 11 and a second shell 12 connected to each other. The first shell 11 and the second shell 12 respectively have a first cavity 111 and a second cavity 121 with one end open and the other end closed. The first stopper 20 is matched with the shell 10. The packaging structure 100 has a packaging state and a storage state. When the packaging structure 100 is in the packaging state, the first shell 11 and the second shell 12 are connected along a first direction, and the first cavity 111 and the second cavity 121 are connected to form a receiving cavity 13 for receiving the to-be-packaged item 200. The first stopper 20 is received in the receiving cavity 13, and the first stopper 20 is configured to provide at least one first stopper for the to-be-packaged item 200 to prevent the to-be-packaged item 200 from moving along a second direction intersecting the first direction. force; when the packaging structure 100 is in the storage state, the first shell 11 and the second shell 12 are arranged side by side along the second direction, and the opening of the first shell 11 and the opening of the second shell 12 are located on the same side of the shell 10, and the first limiting member 20 can be selectively accommodated in any one of the first cavity 111 and the second cavity 121, and the first cavity 111 or the second cavity 121 currently accommodating the first limiting member 20 is divided by the first limiting member 20 to form at least two first sub-cavities 112 that are connected to their own openings.

[0052] Specifically, when the packaging structure 100 is in a packaging state, the first shell 11 and the second shell 12 are docked to form a closed receiving cavity 13, and the first limiting member 20 and the item to be packaged 200 are both received in the receiving cavity 13. The shell 10 can package and protect the item to be packaged 200 to prevent the item to be packaged 200 from being damaged during transportation, and the first limiting force applied by the first limiting member 20 to the item to be packaged 200 has a limiting effect on the item to be packaged 200, which can prevent the item to be packaged 200 from shaking relative to the shell 10 during transportation, so that the item to be packaged 200 has a better fixing effect. When the packaging structure 100 is in the storage state, the first shell 11 and the second shell 12 are arranged side by side, and the openings of the first shell 11 and the second shell 12 are both located on the same side of the shell 10, and the first stopper 20 can be selectively accommodated in any one of the first cavity 111 and the second cavity 121, and the first cavity 111 or the second cavity 121 currently accommodating the first stopper 20 is divided by the first stopper 20 to form at least two first sub-cavities 112 that are connected to the openings thereof, and the entire packaging structure 100 can form a structure similar to a pen holder, and the user can use the packaging structure 100 for storage. Taking the first stopper 20 being placed in the first cavity 111 and dividing the first cavity 111 into two first sub-cavities 112 as an example, a ballpoint pen can be placed in the first first sub-cavity 112, a pencil can be placed in the second first sub-cavity 112, and a ruler can be placed in the second cavity 121. It can be seen that the above-mentioned packaging structure 100 can not only be used to package and protect the items to be packaged 200, but can also be transformed into a structure similar to a pen holder for storage, thereby realizing the reuse of the packaging structure 100.

[0053] Optionally, the first shell 11 and the second shell 12 can be cylindrical, conical, or other irregular shapes. Specifically, the first shell 11 and the second shell 12 are both frame-tube structures, and the first shell 11 and the second shell 12 extend along the first direction. Optionally, the first shell 11 and the second shell 12 can have the same length or different lengths. In one embodiment, the length of the first shell 11 is less than the length of the second shell 12, and the depth of the first cavity 111 is less than the depth of the second cavity 121. Therefore, when the packaging structure 100 is in a storage state, the user can choose to store the first cavity 111 of the first shell 11 or the second cavity 121 of the second shell 12 according to the length of the to-be-stored piece 40, so as to facilitate the user to take and place the to-be-stored piece 40. For example, assuming that the to-be-stored piece 40 includes a ballpoint pen and a ruler, and the length of the ballpoint pen is less than the length of the ruler, when storing, the ballpoint pen can be placed in the first cavity 111 and the ruler can be placed in the second cavity 121.

[0054] The open end face of the first shell 11 is defined as the first open end face 113, the closed end face of the first shell 11 is defined as the first closed end face 114, the open end face of the second shell 12 is defined as the second open end face 122, and the closed end face of the second shell 12 is defined as the second closed end face 123. Optionally, the first open end face 113 and the first closed end face 114 can be arranged in parallel or tilted, and the second open end face 122 and the second closed end face 123 can be arranged in parallel or tilted. Preferably, the first open end face 113 and the first closed end face 114 are tilted, and the second open end face 122 and the second closed end face 123 are also tilted, and the openings on the first shell 11 and the second shell 12 are both tilted openings. Moreover, when the first shell 11 and the second shell 12 are docked, the first open end face 113 and the second open end face 122 fit together.

[0055] Therefore, in the first shell 11, in the extension direction of the first opening end face 113, the distance from the first opening end face 113 to the first closed end face 114 shows a trend of gradually increasing or gradually decreasing, and the depth of the first cavity 111 also shows a trend of gradually increasing or gradually decreasing. Therefore, when storing the to-be-packaged item 200, it can be placed in different positions of the first cavity 111 according to the length of the to-be-packaged item 200, so as to ensure that part of the to-be-packaged item 200 can protrude outside the first shell 11, so as to facilitate taking and placing. Of course, when it is necessary to completely contain the to-be-packaged item 40, the to-be-packaged item 40 can also be placed at a position where the depth is equal to or greater than the length of the to-be-packaged item 40, so that the to-be-packaged item 40 can be completely stored in the first shell 11. Correspondingly, in the second shell 12, in the extension direction of the second opening end face 122, the distance from the second opening end face 122 to the second closed end face 123 shows a trend of gradually increasing or gradually decreasing, and the depth of the second cavity 121 also shows a trend of gradually increasing or gradually decreasing, so when storing the to-be-packaged item 200, it can be placed in different positions of the second cavity 121 according to the length of the to-be-packaged item 200, so as to ensure that part of the to-be-packaged item 200 can protrude outside the second shell 12, so as to facilitate taking and placing. Of course, when it is necessary to completely contain the to-be-packaged item 40, the to-be-packaged item 40 can also be placed at a position where the depth is equal to or greater than the length of the to-be-packaged item 40, so that the to-be-packaged item 40 can be completely stored in the second shell 12.

[0056] Please refer again Figure 1 Optionally, there is an angle between the first direction and the second direction, and the angle can be 15°, 50°, 90°, 120°, etc. In the following embodiments, the housing 10 is a rectangular parallelepiped, the first direction and the second direction are vertically arranged, and the first direction is Figure 1 The direction indicated by the double-headed arrow a in the figure is the length direction of the housing 10, and the second direction is Figure 2In the direction indicated by the double-headed arrow b (the width direction of the shell 10), the length of the first shell 11 is smaller than the length of the second shell 12, and when the packaging structure 100 is in the packaging state, the first limiting member 20 is accommodated in the second shell 12, and when the packaging structure 100 is in the storage state, the first limiting member 20 is accommodated in the first shell 11 as an example.

[0057] Please also read Figure 6 Optionally, a limiting groove may be provided on the first limiting member 20, and a limiting hole, a limiting column and other structures may limit the first limiting member 20. In one embodiment, a first limiting hole 212 is provided on the first limiting member 20, and when the packaging structure 100 is in the packaging state, the item 200 to be packaged is passed through the first limiting hole 212 and is clamped with the first limiting hole 212. Specifically, when the packaging structure 100 is in the packaging state, the central axis of the first limiting hole 212 extends along the first direction, and the hole wall of the first limiting hole 212 limits the item 200 to be packaged along the circumference of the item 200 to be packaged, so that the item 200 to be packaged has a better fixing effect to prevent the item 200 to be packaged from shaking. Moreover, due to the setting of the first limiting hole 212, there is no contact between the outer peripheral wall of the package 200 to be packaged and the inner wall of the outer shell 10. The package 200 to be packaged and the packaging structure 100 covering the package 200 are collectively referred to as the packaging design structure. Therefore, when multiple packaging design structures are stacked and transported, even if the multiple packaging design structures collide with each other, the first limiting member 20 can buffer the package 200 to prevent the package 200 from being damaged.

[0058] It should be noted that, in this embodiment, the first stopper 20 can be detachably fixed to the cavity wall of the receiving cavity 13 by fasteners, or can also be clamped in the receiving cavity 13. Preferably, the first stopper 20 is clamped in the receiving cavity 13, so that the use of fasteners can be reduced, which is convenient for reducing the manufacturing cost of the packaging structure 100.

[0059] Specifically, the first limiting member 20 can be a plate-like structure, or can also be a combined structure. In one embodiment, the first limiting member 20 includes a first limiting portion 21 and a first supporting portion 22 connected to the first limiting portion 21; when the packaging structure 100 is in the packaging state, the first limiting portion 21 is spaced along the first direction at a side of the first supporting portion 22 facing the package 200, and a first limiting hole 212 is provided on the first limiting portion 21, and the package 200 is passed through the first limiting hole 212 and abuts against the first supporting portion 22. By providing the first supporting portion 22, the first supporting portion 22 can limit the package 200 along the axial direction of the package 200 and from one end of the package 200, thereby further preventing the package 200 from shaking along its axial direction. Moreover, due to the setting of the first support portion 22, the end of the package 200 that is matched with the first limit member 20 is also not in contact with the inner wall of the outer shell 10. Therefore, when multiple packaging design structures are stacked and transported, the first support portion 22 can further buffer the package 200, thereby further preventing the package 200 from being damaged, so that the package 200 has better transportation safety.

[0060] Optionally, the first limiting portion 21 may be one or more. If there are more than one first limiting portion 21, when the packaging structure 100 is in the packaging state, the multiple first limiting portions 21 are sequentially arranged at intervals along the first direction, and the multiple first limiting portions 21 are distributed on the side of the first support portion 22 facing the package 200. By providing multiple first limiting portions 21, each first limiting portion 21 can limit the package 200 from different positions and along the circumference of the package 200, so that the package 200 has a better fixing and buffering effect. The following embodiments are all described by taking one first limiting portion 21 as an example.

[0061] Furthermore, the first stopper 20 further includes a first contact portion 23 connected to the first support portion 22; when the packaging structure 100 is in the packaging state, the first contact portion 23 is spaced along the first direction at a side of the first support portion 22 facing away from the first stopper 21, and contacts the cavity wall of the receiving cavity 13 facing away from the first stopper 21. By providing the first contact portion 23, the first stopper 20 can be stably installed in the receiving cavity 13, and thus, the stability of the installation of the package 200 can be improved.

[0062] Taking the example that when the packaging structure 100 is in the packaging state, the first limiting member 20 is accommodated in the second cavity 121, and when the packaging structure 100 is in the storage state, the first limiting member 20 is accommodated in the first cavity 111, when the packaging structure 100 is in the packaging state, the first abutment portion 23 abuts against the cavity wall of the second cavity 121 facing away from the second closed end face 123.

[0063] Furthermore, when the packaging structure 100 is in the storage state, the first supporting portion 22 separates the first cavity 111 or the second cavity 121 currently accommodating the first limiting member 20 to form two first sub-cavities 112, and the first limiting portion 21 and the first abutting portion 23 respectively abut against the cavity walls of the first cavity 111 or the second cavity 121 currently accommodating the first limiting member 20.

[0064] Specifically, the first cavity 111 is defined as having a first cavity wall and a second cavity wall that are opposite and spaced apart in the second direction, and a third cavity wall and a fourth cavity wall that are opposite and spaced apart in a third direction intersecting the first direction and the second direction, and the second cavity 121 is defined as having a fifth cavity wall and a sixth cavity wall that are opposite and spaced apart in the second direction, and a seventh cavity wall and an eighth cavity wall that are opposite and spaced apart in the third direction. Regardless of whether the packaging structure 100 is in a packaging state or a storage state, if the first stopper 20 is received in the first cavity 111, the first stopper 21 and the first abutting portion 23 abut against the third cavity wall and the fourth cavity wall respectively, and if the first stopper 20 is received in the second cavity 121, the first stopper 21 and the first abutting portion 23 abut against the seventh cavity wall and the eighth cavity wall respectively. In this way, the reliability of the installation of the first stopper 20 can be effectively improved, so that the formed first sub-cavity 112 has better stability.

[0065] Please refer again Figure 1 Optionally, there is an angle between the first direction and the third direction, and the angle may be 15°, 50°, 90°, 120°, etc. There is an angle between the second direction and the third direction, and the angle may be 15°, 50°, 90°, 120°, etc. In the following embodiments, the angles between the third direction and the first direction, and between the third direction and the second direction are both 90°, that is, the first direction and the third direction are perpendicular, the second direction and the third direction are perpendicular, and the third direction is Figure 1 The description will be made by taking the direction indicated by the double-headed arrow c in FIG. 1 (the thickness direction of the housing 10 ) as an example.

[0066] The first position-limiting member 20 further includes two first connection portions 24 ; the two first connection portions 24 are spaced apart at opposite ends of the first position-limiting portion 21 along the second direction, and each first connection portion 24 is connected to the first position-limiting portion 21 , the first support portion 22 and the first abutting portion 23 .

[0067] Specifically, no matter the packaging structure 100 is in the packaging state or the storage state, if the first stopper 20 is received in the first cavity 111, the two first connection parts 24 are respectively in contact with the first cavity wall and the second cavity wall, and if the first stopper 20 is received in the second cavity 121, the two first connection parts 24 are respectively in contact with the fifth cavity wall and the sixth cavity wall. In this way, no matter the packaging structure 100 is in the packaging state or the storage state, the first stopper 20 can be clamped in the housing 10, so that the first stopper 20 has better installation stability.

[0068] In one embodiment, the first position-limiting member 20 has a placement side, on which a placement position is provided; when in the storage state, the placement position is located outside the first cavity 111 and the second cavity 121. The placement position can be used to place items such as mobile phones and tablets waiting to be placed.

[0069] Specifically, when the packaging structure 100 is in the packaging state, the first stopper 20 is located in the second cavity 121, and the first stopper 20 has a first side edge and a second side edge that are opposite and spaced apart along the third direction; when the packaging structure 100 is in the packaging state, the first stopper 20 is accommodated in the first cavity 111, and the first side edge protrudes outside the first cavity 111, the second side edge abuts against the cavity wall of the first cavity 111 that is away from the first closed end surface 114, and a placement notch 27 is provided on the first side edge, and the placement notch 27 forms a placement position. The method of forming the placement position by the placement notch 27 not only makes the formation method of the placement position relatively simple, but also makes it convenient for users to place the items to be placed.

[0070] Specifically, the first limiting portion 21 has a first limiting side edge and a second limiting side edge that are opposite and spaced apart in the third direction, the first supporting portion 22 has a first supporting side edge and a second supporting side edge that are opposite and spaced apart in the third direction, the first abutting portion 23 has a first abutting side edge and a second abutting side edge that are opposite and spaced apart in the third direction, the first limiting side edge, the first supporting side edge and the first abutting side edge together form the first side edge, the second limiting side edge, the second supporting side edge and the second abutting side edge together form the second side edge, a limiting notch 218 is provided on the first limiting side edge, a supporting notch 225 is provided on the first supporting side edge, and an abutting notch 236 is provided on the first abutting side edge, and the limiting notch 218, the supporting notch 225 and the abutting notch 236 are combined to form a placement notch 27. Therefore, when the to-be-placed piece is placed in the placement position, the first limiting portion 21, the first supporting portion 22 and the first abutting portion 23 can support the to-be-placed piece from different positions, so that the to-be-placed piece has a stable support effect.

[0071] Please also read Figure 7The packaging structure 100 also includes a second limiting member 30, which is connected to the shell 10; when the packaging structure 100 is in a packaging state, the first limiting member 20 and the second limiting member 30 are distributed at opposite ends of the packaged item 200, and the second limiting member 30 is configured to provide at least one second limiting force for the packaged item 200 to prevent the packaged item 200 from moving along a second direction.

[0072] By setting a second limiting member 30, the second limiting member 30 cooperates with the first limiting member 20 to limit and fix the package 200 from two opposite ends of the package 200. In this way, the fixing and buffering effects of the package 200 can be further improved, so that the packaging structure 100 has better packaging reliability.

[0073] When the packaging structure 100 is in the storage state, the second stopper 30 can be stored in one of the first sub-cavities 112 separated and formed by the first stopper 20, and the first sub-cavity 112 is further divided into at least two storage cavities, and each storage cavity is connected to the opening of the first cavity 111 or the second cavity 121 that separates and forms at least two first sub-cavities 112, and each storage cavity can be used to store pencils, rulers, etc.; or, one of the first stopper 20 and the second stopper 30 is stored in any one of the first cavity 111 and the second cavity 121, and the first stopper 20 and the second stopper 30 are stored in any one of the first cavity 111 and the second cavity 121. The other of the positioning member 20 and the second limiting member 30 is accommodated in the other of the first cavity 111 and the second cavity 121, and the first cavity 111 or the second cavity 121 that accommodates the second limiting member 30 is divided by the second limiting member 30 to form at least two second sub-cavities connected to its own opening, and the second sub-cavity can also be used to store rulers, pens and waiting storage items 40; in some other embodiments, when the packaging structure 100 is in the storage state, the second limiting member 30 can also be directly placed on the bottom of the first cavity 111 or the second cavity 121 and used to support the items 40 to be stored. The following embodiments are all described by taking the example that when the packaging structure 100 is in the packaging state, the first stopper 20 and the second stopper 30 are respectively received in the second cavity 121 and the first cavity 111, and when the packaging structure 100 is in the receiving state, the first stopper 20 and the second stopper 30 are respectively received in the first cavity 111 and the second cavity 121, and the second stopper 30 is located at the bottom of the second cavity 121 and is used to support the to-be-received item 40. Since the depth of the second cavity 121 is deeper than that of the first cavity 111, the second stopper 30 is received at the bottom of the second cavity 121, so that the depth of the part of the second cavity 121 that can be used to receive the to-be-received item 40 becomes shallow, so that the to-be-received item 40 can be prevented from being completely received in the second cavity 121 and being inconvenient to take out and put.

[0074] Optionally, a limiting groove may be provided on the first limiting member 20, and a limiting hole, a limiting column and other structures may be used to limit the first limiting member 20. In one embodiment, a second limiting hole 312 is provided on the second limiting member 30. When in the packaging state, the second limiting member 30 is clamped in the receiving cavity 13, and one end of the packaged item 200 away from the first limiting member 20 is passed through the second limiting hole 312 and clamped with the second limiting hole 312. Specifically, when the packaging structure 100 is in the packaging state, the central axis of the second limiting hole 312 extends along the first direction, and the hole wall of the second limiting hole 312 limits the packaged item 200 along the circumference of the packaged item 200, so that the packaged item 200 has a better fixing effect to prevent the packaged item 200 from shaking. Moreover, due to the setting of the second limiting hole 312, there is no contact between the outer wall of the package 200 and the inner wall of the outer shell 10. Therefore, when multiple packaging design structures are stacked or transported, the multiple packaging design structures can be prevented from squeezing and colliding with each other to damage the package 200 in the packaging structure 100.

[0075] Specifically, the second limiting member 30 can be a plate-like structure, or can also be a combined structure. In one embodiment, the second limiting member 30 includes a second limiting portion 31 and a second supporting portion 32 connected to the second limiting portion 31; when the packaging structure 100 is in the packaging state, the second limiting portion 31 is arranged at intervals along the first direction on the side of the second supporting portion 32 facing the to-be-packaged item 200, and a second limiting hole 312 is provided on the second limiting portion 31, and one end of the to-be-packaged item 200 away from the first limiting member 20 is penetrated through the second limiting hole 312 and abuts against the second supporting portion 32. By providing the second supporting portion 32, the second supporting portion 32 can limit the to-be-packaged item 200 along the axial direction of the to-be-packaged item 200 and from the one end of the to-be-packaged item 200 away from the first limiting member 20, thereby further preventing the to-be-packaged item 200 from shaking along its axial direction. Moreover, due to the provision of the second support portion 32, there is no contact between the end of the package 200 that is matched with the second limit member 30 and the inner wall of the outer shell 10. Therefore, when multiple packaging design structures are stacked and transported, even if multiple packaging design structures collide, the second support portion 32 can buffer and prevent the package 200 from being damaged, thereby ensuring better transportation safety.

[0076] Furthermore, the second stopper 30 further includes two second connection parts 33, which are arranged at intervals on opposite sides of the second stopper 31 along the second direction, or the two second connection parts 33 are arranged at intervals on opposite sides of the second stopper 31 along the third direction, and each second connection part 33 is connected to the second stopper 31 and the second support part 32. Taking the two second connection parts 33 arranged at intervals along the second direction as an example, whether the packaging structure 100 is in the packaging state or the storage state, if the second stopper 30 is accommodated in the first cavity 111, the two second connection parts 33 are respectively connected to the first cavity wall and the second cavity wall, and if the second stopper 30 is accommodated in the second cavity 121, the two second connection parts 33 are respectively connected to the fifth cavity wall and the sixth cavity wall. In this way, the installation stability of the second stopper 30 can be effectively improved, so that the installation of the package 200 to be packaged is also more stable.

[0077] The following embodiments are all described by taking the case where the packaging structure 100 is in a packaging state, the first limiting member 20 is accommodated in the second cavity 121, the second limiting member 30 is accommodated in the first cavity 111, and the second limiting portion 31 is arranged toward the first limiting member 20, and the second supporting portion 32 is arranged on the side of the second limiting portion 31 facing away from the first limiting member 20; when the packaging structure 100 is in a storage state, the first limiting member 20 is accommodated in the first cavity 111, the second limiting portion 31 is accommodated in the second cavity 121, and the second limiting portion 31 is arranged toward the opening of the second cavity 121, and the second supporting portion 32 is arranged on the side of the second limiting portion 31 facing away from the opening of the second cavity 121.

[0078] Please also read Figure 8 The packaging structure 100 further includes a storage member 40, which is selectively received in the first cavity 111 or the second cavity 121, and has a storage groove 41. Specifically, when the packaging structure 100 is in the packaging state, the storage member 40 is received in the receiving cavity 13, and abuts between the first limiting member 20 and the cavity wall of the receiving cavity 13 along the first direction, or abuts between the second limiting member 30 and the cavity wall of the receiving cavity 13 along the first direction. The spare parts of the to-be-packaged item 200, such as a power cord, instruction manual, etc., can be received in the storage groove 41 of the to-be-received item 40. When the packaging structure 100 is in the receiving state, the to-be-received items 40 of small volume, such as erasers and pencil sharpeners, can be received in the storage groove 41. By providing the storage member 40, when the packaging structure 100 is in different states, the storage member 40 can be used to store different components, thereby effectively improving the storage effect of the packaging structure 100 and providing users with a better user experience.

[0079] Specifically, when the packaging structure 100 is in the packaging state, if the storage member 40 abuts between the first stopper 20 and the cavity wall of the receiving cavity 13, and the opening of the storage groove 41 is set toward the first stopper 20, if the storage member 40 abuts against the second stopper 30 and the cavity wall of the receiving cavity 13, and the opening of the storage groove 41 is set away from the second stopper 30, the stability of the storage member 40 in the first direction can be improved, thereby preventing the storage member 40 from shaking. Moreover, in the second direction and the third direction, the storage member 40 abuts against the cavity wall of the first cavity 111 or the second cavity 121, so that the reliability of the installation of the storage member 40 can be further improved. When the packaging structure 100 is in the storage state, the storage piece 40 can also be accommodated in either the first cavity 111 or the second cavity 121, and in the second direction and the third direction, the storage piece 40 abuts against the cavity wall of the first cavity 111 or the second cavity 121 in which it is accommodated. At this time, the storage piece 40 can be used to accommodate small-volume items 40 to be stored, such as erasers. The following embodiments are all based on the case where the packaging structure 100 is in a packaging state, the storage piece 40 is accommodated in the first cavity 111, and the storage piece 40 abuts between the second limiting piece 30 and the cavity wall of the first cavity 111 facing away from the first closed end surface 114, and the opening of the receiving groove is set away from the second limiting piece 30. When the packaging structure 100 is in a storage state, the storage piece 40 is accommodated in the second cavity 121, and the storage piece 40 abuts between the second limiting piece 30 and the cavity wall of the second cavity 121 facing away from the second closed end surface 123. In addition, the opening of the storage groove 41 is set toward the second limiting piece 30 for explanation.

[0080] Further, the first shell 11 has an inlet and outlet 14 in communication with the first cavity 111 at one end away from the opening thereof, and the storage member 40 is telescopically disposed through the inlet and outlet 14 of the first shell 11; or, the second shell 12 has an inlet and outlet 14 in communication with the second cavity 121 at one end away from the opening thereof, and the storage member 40 is telescopically disposed through the inlet and outlet 14 of the second shell 12. By providing the inlet and outlet 14, whether the packaging structure 100 is in a packaging state or a storage state, it is also convenient for the storage member 40 to enter and exit the first cavity 111 or the second cavity 121 in which it is stored, so that it is convenient for users to take and put the components placed in the storage slot 41.

[0081] Furthermore, a door portion 15 is provided at the position where the entrance and exit 14 is opened in the first shell 11 or the second shell 12. When the storage component 40 is stored in the first cavity 111 or the second cavity 121, the door portion 15 covers the entrance and exit 14 to close the entrance and exit 14. When the user needs to take or place components stored in the storage component 40, the door portion 15 is opened so that the storage component 40 can freely enter and exit the entrance and exit 14.

[0082] Furthermore, the door portion 15 is also provided with a position-avoiding notch 152, and the storage member 40 is provided with a push-pull portion 42 corresponding to the position of the position-avoiding notch 152. When the packaging structure 100 is in the packaging state, the push-pull portion 42 is inserted into the position-avoiding notch 152, so that the user can conveniently hold the push-pull portion 42 and operate the storage member 40 to slide in and out of the first cavity 111 or the second cavity 121, and the door portion 15 is opened under the pressure of the storage member 40.
