[0061] The lining portion 10 may also be located at the bottom of the fixing portion 09 and fit the inner surface of the inner enclosure 02. The shape and size of the lining portion 10 are adapted to the inner surface of the inner enclosure 02 to form a receiving space. This receiving space is used to place and fix the product in the package to ensure the stability and safety of the product.

[0062] A complete structure is formed between the fixing portion 09 and the inner lining portion 10 of the inner baffle 07, ensuring the stability and functionality of the inner baffle 07. At the same time, a semicircular opening 08 is provided on the fixing portion 09 for engaging and fixing with the pressing structure 03 to realize the self-locking opening function of the packaging box.

[0063] The inner baffle 07 in this embodiment can not only be fixed on the inner enclosure 02, but also provide a storage space for placing the product in the package. At the same time, the combination of the fixing portion 09 of the inner baffle 07 and the inner lining portion 10 can also enhance the overall stability and firmness of the packaging box, thereby improving the quality and use effect of the packaging box.

[0064] In an optional embodiment, the top edge of the inner stop 07 is flush with the top edge of the inner periphery 02 .

[0065] In this optional embodiment, the top edge of the inner guard 07 is flush with the top edge of the inner enclosure 02.

In this embodiment, the top edge of the inner guard 07 is located at the top edge of the inner enclosure 02, and the two are kept on the same horizontal line. The purpose of this design is to make the connection between the inner guard 07 and the inner enclosure 02 tighter, without protrusion or depression, and maintain the overall appearance and aesthetics of the packaging box.

[0066] See also Figure 4 and Figure 5In an optional embodiment, the pressing structure 03 also includes a mounting plate 11 and a spring member 12, the mounting plate 11 is provided with a mounting groove 15, the spring member 12 is installed in the mounting groove 15, the pressing portion 06 is connected to the spring member 12, and the mounting plate 11 is fixed on the inner circumference 02.

[0067] It is mentioned in the above-mentioned embodiments that the pressing structure 03 in the present application can have a variety of implementation methods, for example, it can be a spring-type pressing structure 03, so this embodiment provides a specific implementation method of the spring-type pressing structure 03. In this embodiment, the pressing structure 03 also includes a mounting plate 11 and a spring member 12. These two components are combined with the pressing portion 06 to jointly realize the self-locking opening function of the packaging box.

[0068] The mounting plate 11 is a component of the pressing structure 03, and a mounting groove 15 is provided on the mounting plate 11. The mounting plate 11 is connected to the spring member 12 through the mounting groove 15 and fixed on the inner periphery 02. The main function of the mounting plate 11 is to provide support and fixation so that the pressing structure 03 can be stably installed on the inner periphery 02. The spring member 12 is installed in the mounting groove 15. The spring member 12 is connected to the pressing portion 06 through elastic force, which realizes the activity and movement of the pressing portion 06. The function of the spring member 12 is to enable the pressing portion 06 to flexibly move from the first position state to the second position state, thereby realizing the self-locking of the packaging box.

[0069] The pressing part 06 is movably connected to the mounting plate 11 by being connected to the spring member 12. The pressing part 06 has a first position state and a second position state. When the pressing part 06 is in the first position state, the packaging box is in an open state; and when the pressing part 06 is in the second position state, the packaging box is in a closed state.

[0070] Through the combination of the mounting plate 11, the spring member 12 and the pressing portion 06, the user can control the opening and closing state of the packaging box by pressing the pressing portion 06. When the user presses the pressing portion 06, the spring member 12 is compressed, so that the pressing portion 06 moves from the second position state to the first position state, at which time the position of the top surface of the pressing portion 06 moves from penetrating the fixing hole 05 to being flush with the surface of the inner periphery, and the pressing portion 06 will be separated from the cooperation with the fixing hole 05, so that the packaging box is unlocked; and when the user releases the pressing portion 06, the spring member 12 returns to its original state, and the pressing portion 06 returns to the first position state, at which time the position of the top surface of the pressing portion 06 moves from being flush with the surface of the inner periphery to the position penetrating the fixing hole 05, and maintains this state under the elastic force of the spring member 12, so that the self-locking of the packaging box can be achieved.

[0071] See also Figure 4 and Figure 5 In an optional embodiment, a limiting portion 13 is provided on the pressing portion 06 .

[0072] In order to prevent the elastic force of the spring from excessively popping out the pressing portion 06 and thus detaching from the mounting groove 15, a limiting portion 13 is provided on the pressing portion 06. This design adds a limiting portion to the structure of the pressing portion 06, which is used to limit the maximum pop-up distance of the pressing portion 06 in the second position state, thereby ensuring that the pressing portion 06 will not excessively pop out and detach from the mounting groove.

[0073] Specifically, the limiting portion 13 is located at one end or multiple sides of the pressing portion 06, and forms an appropriate limiting structure with the mounting groove. For example, the limiting portion 13 may include a hook for limiting, and a rod with a certain length, the hook is fixed to the pressing portion 06 through the rod, and the rod has a suitable length in order to provide a certain stroke for the pressing movement of the pressing portion 06. When the pressing portion 06 moves from the first position state to the second position state, the limiting portion 13 will contact the mounting groove or a structure near it, limiting the ejection distance of the pressing portion 06, and preventing the pressing portion 06 from being excessively ejected and detached from the mounting groove.

[0074] By providing the limiting portion 13, the movement range of the pressing portion 06 can be effectively controlled to ensure that the pressing portion 06 always remains in the installation slot in the second position state without falling off or failing. This design can improve the stability and reliability of the packaging box and ensure the normal function of the packaging box during use.

[0075] In an optional embodiment, a lower box 14 is further included, and the lower box 14 is fixed to the outside of the inner enclosure 02.

[0076] In this optional embodiment, a lower box 14 is also included, and the lower box 14 is fixed to the outside of the inner periphery 02. Such a design can increase the stability and firmness of the packaging box, while providing better support and protection.

[0077] The lower box 14 is the bottom part of the packaging box, which is used to support and fix the structure of the entire packaging box. The lower box 14 can be an open container, which is used to place and protect the product in the package.

[0078] The lower box 14 is fixed to the outside of the inner enclosure 02, which can be achieved by various fixing methods, such as bonding, snapping or other mechanical connection methods. This design allows the lower box 14 to be tightly connected to the inner enclosure 02, increasing the overall stability and firmness of the packaging box. The inner enclosure 02 can be embedded in the lower box 14, for example, the inner enclosure 02 can be partially surrounded by the lower box 14, or the inner enclosure 02 can be completely surrounded by the inner enclosure 02.

[0079] By fixing the lower box 14 to the outside of the inner enclosure 02, the structural stability of the packaging box can be effectively enhanced to prevent the packaging box from tilting or collapsing during transportation or use. At the same time, the existence of the lower box 14 can also provide additional support and protection to ensure that the product in the package is not easily damaged or deformed.
