[0030] In order to make the technical means, creative features, purposes and effects of the present application easy to understand, the present application will be further described below in combination with specific embodiments.

[0031] Referring to Figures 1 to 8 Fig. 1, a multifunctional combined plastic box with a modular separation structure includes an outer box 1 and a modular inner box 2. Referring to Fig. 2, an outer box cover 4 on the outer box 1 is connected to an outer box body 3 through buckling. The outer box 1 and the modular inner box 2 are connected through plug-in. In use, different sizes of modular inner boxes 2 can be combined at will according to the needs of the user and connected to the outer box 1 through plug-in. The modular inner boxes of different sizes but using the same way can be selectively assembled in the outer box, meeting the needs of flexible classification and storage. Specifically, the outer box body 3 includes a side wall 5 and an outer box bottom plate 6. Referring to Fig. 3, different sizes of modular inner boxes 2 are placed in a containing cavity 100 formed by the side wall 5 and the outer box bottom plate 6 to accommodate the modular inner boxes 2, and the bottom of the modular inner box 2 is supported by a support plate 7. The box cover of the modular inner box 2 is a transparent material cover, through which the specific hand account stationery stored in the modular inner box 2 can be seen at a glance.

[0032] The support plate 7 is provided with a hole 8, and the outer box bottom plate 6 is provided with a connecting sleeve 9 protruding upward corresponding to the hole 8. The top surface of the connecting sleeve 9 is connected with the bottom surface of the support plate 7, and the top surface of the connecting sleeve 9 also acts on the support plate 7 to provide support to the support plate 7. The connecting plug 11 is inserted into the mounting blind hole 10 at the bottom of the modular inner box 2 through the hole 8, and the connection between the connecting plug 11 and the mounting blind hole 10 is inserted into each other, thereby stabilizing the connection between the outer box 1 and the modular inner box 2 and improving the protection of the notebook stationery when carrying out.

[0033] When the modular inner box 2 needs to be taken out, the suction magnet is placed at the bottom of the outer box 1, and the iron sleeve 12 wrapped around the bottom of the connecting plug 11 is attracted to each other by the suction magnet. The magnetic force generated by the magnet on the iron sleeve 12 is greater than the sum of the elastic force of the first plastic spring 13 and the friction force of the mounting blind hole 10 on the surface of the connecting plug 11. When the magnet approaches the connecting plug 11 that needs to be retracted, the connecting plug 11 moves downward from the mounting blind hole 10 and is separated from the mounting blind hole 10. After contacting the connection between the modular inner box 2 and the outer box 1, the pull ring on the outer box 2 is pulled out.

[0034] At the same time, because of the existence of the connecting sleeve 9, when the connecting plug 11 is compressed, it will not affect the balance of the support plate 7 after losing pressure due to the pushing force of the first plastic spring 13, thereby protecting other modular inner boxes 2 still arranged in the inner cavity 100 from being affected.

[0035] The bottom of the modular inner box 2 is provided with a mounting blind hole 10.

[0036] The connecting sleeve 9 includes a cylinder 14 and a limiting top ring 15. The limiting top ring 15 is connected to the top of the cylinder 14, and the ring hole on the limiting top ring 15 is matched with the connecting plug 11. The inner diameter of the ring hole on the limiting top ring 15 is slightly smaller than the inner diameter of the hole 8. The inner wall of the hole 8 is provided with a damping layer 19, and the outer diameter of the iron sleeve 12 is equal to the inner diameter of the cylinder 14.

[0037] The inner wall of the cylinder 14 is provided with a limiting groove 16 recessed inward, and the iron sleeve 12 is provided with a sliding strip 17 protruding outward.

[0038] The limiting top ring 15 is provided with a shock-absorbing layer at the contact position with the iron sleeve 12.

[0039] The inner wall of the hole 8 is provided with a damping layer.

[0040] The outer box cover 4 is provided with a pressing cylinder 21 protruding towards the outer box body 3, and a pressing rod 22 is inserted into the pressing cylinder 21. The pressing cylinder 21, the second plastic spring 23, and the pressing rod 22 are arranged on the outer box cover to clamp the modular inner box 2 arranged in the outer box body 3, thereby improving the stability of the modular inner box 2 in the outer shell when carrying out and improving the protection of the notebook stationery when carrying out.

[0041] The compression rod 22 is connected with the outer box cover 4 through a second plastic spring 23.

[0042] The compression rod 22 is provided with an obstruction ring 24, which is arranged at a position close to the outer box cover 424 of the compression rod 22.

[0043] Finally, it should be pointed out that the above embodiments are only used to illustrate the technical solutions of the present application and are not limiting. Although the present application has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present application can be modified or replaced equivalently without departing from the purpose and scope of the present application, and all should be covered in the scope of the claims of the present application.
