[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0020] Reference Figures 1 to 3 , this application provides a buckle structure, including: a first main board 1, which is provided with a first groove along the first direction A; a second main board 2, which is arranged on the first main board 1, and at least one second groove 3 is provided along the second direction B on the first main board 1 and the second main board 2; an insertion layer 4, which is movably inserted into the first groove, a clamping strip 5 is arranged along the first direction A on the insertion layer 4, and a first clamping block 6 is arranged on the outer side of the insertion layer 4; at least one limiting layer 7, which is movably inserted into the second groove 3, a card slot 8 for the clamping strip 5 to pass through is provided along the first direction A at the bottom of each limiting layer 7, and a second clamping block 9 is arranged on the outer side of the limiting layer 7; the number of the second grooves 3 corresponds to the number of the limiting layers 7; a third main board 10, which is arranged on the second main board 2.

[0021] The main boards with multi-layer structure design (including the first main board 1, the second main board 2 and the third main board 10) not only serve as a stable carrier for bearing components such as the insertion layer 4 and the limiting layer 7, but also provide installation and movement space for the insertion layer 4 and the limiting layer 7.

[0022] In some embodiments, the first direction A and the second direction B are perpendicular to each other on the same horizontal plane.

[0023] In some embodiments, the thickness of the first main board 1 is 3N, the depth of the first groove is 2N, the thickness of the second main board 2 is N, the depth of the second groove 3 is 2N, the thickness of the insertion layer 4 is N, the thickness of the clamping strip 5 is N, the thickness of the limiting layer 7 is 2N, the depth of the card slot 8 is N, and the thickness of the third main body is N. The limitation of the thickness and depth is to make the movement and locking of the components more reasonable.

[0024] In some embodiments, the width of the clamping strip 5 is M, and the width of the card slot 8 is greater than M, ensuring that the insertion layer 4 can smoothly pass through the limiting layer 7 when moving along the first direction A.

[0025] Embodiment 1, the number of the limiting layers 7 is two. When the two limiting layers 7 are completely inside the second groove 3, the card slots 8 in the two limiting layers 7 are parallel to each other and not on the same straight line.

[0026] Embodiment 2, the number of the limiting layers 7 is three. When the three limiting layers 7 are completely inside the second groove 3, the card slots 8 in the adjacent limiting layers 7 are parallel to each other and not on the same straight line.

[0027] Embodiment 3. There is no specific requirement for the number of the limiting layers 7. Designers can reasonably design according to actual needs. For example, the number of the limiting layers 7 can be two, three, or four. The preset position of each limiting layer 7 corresponds to a corresponding digital password. The more the number of the limiting layers 7, the higher the confidentiality of the buckle structure. In this design, by setting multiple limiting layers 7 and setting the slots 8 at corresponding preset positions for each limiting layer 7, the preset positions of the multiple slots 8 form a string of digital passwords, making the buckle structure have higher security.

[0028] Based on the buckle structure of the present application, the movement of the insertion layer 4 is restricted by the position of the limiting layer 7, so that the self-locking or opening of the entire buckle structure can be realized, and the operation of the entire unlocking or locking is convenient.

[0029] The buckle structure has a closed state and an open state. Among them, the "closed state" can be understood as the limiting layer 7 being in the initial position, that is, completely inserted into the second groove body 3. At this time, the insertion layer 4 is restricted by the limiting layer 7 and cannot move along the first direction A; the "open state" can be understood as pulling the limiting layer 7 from the initial position to the preset position along the second direction B. The preset position is that the slot 8 coincides with the first groove body in the vertical direction. At this time, the limiting layer 7 no longer obstructs the movement of the insertion layer 4 along the first direction A. Pulling the insertion layer 4 along the first direction A can smoothly pass through the limiting layer 7, thus completing the unlocking of the entire buckle structure.

[0030] It should be noted that the "preset position" can be understood as when the limiting layer 7 moves along the second direction B to the preset position in advance, the limiting layer 7 represents a digital password at this position. Only when the limiting layer 7 is moved to the correct preset position (that is, when the digital password is input correctly), the insertion layer 4 is not restricted by the limiting layer 7 and can move along the first direction A, making the buckle structure in the open state.

[0031] A paper box includes: a box body 11 and a cover body 12. The box body 11 has a receiving cavity 13. The box body 11 is detachably connected to the cover body 12. The buckle structure is arranged between the box body 11 and the cover body 12.

[0032] In some embodiments, a first clamping position 14 for the first clamping block 6 to pass through is arranged on the upper part of the box body 11, and a second clamping position 15 corresponding to the first clamping position 14 is arranged on the cover body 12; a third clamping position 16 for the second clamping block 9 to pass through is arranged on the upper part of the box body 11, and a fourth clamping position 17 corresponding to the second clamping position 15 is arranged on the cover body 12; a fifth clamping position 18 for the rear end part of the insertion layer 4 to pass through is arranged on the upper part of the box body 11, and a sixth clamping position 19 corresponding to the fifth clamping position 18 is arranged on the cover body 12; the buckle structure covers the top of the receiving cavity 13.

[0033] The paper box with a buckle structure, on the one hand, the buckle structure has stable buckling, making the whole paper box have good structural reliability; on the other hand, during operation, only by adjusting the relative position and movement direction of the limiting layer 7 and the inserting layer 4 can the quick and reliable locking and unlocking processes of the whole paper box be realized, thus avoiding the safety accident that children casually open the paper box and eat the medicine by mistake.

[0034] When the paper box needs to be unlocked, the limiting layer 7 is pulled to a preset position, so that the inner end of the inserting layer 4 is successively disengaged from the sixth clamping position 19, the fifth clamping position 18, the first clamping position 14 and the second clamping position 15 of the paper box to complete the unlocking. By removing the cover body 12, the separation of the box body 11 and the cover body 12 can be realized, and then the buckle structure is removed to take out the items in the accommodating cavity 13.

[0035] In this application, by pulling the limiting layer 7 to a preset position, a channel for the card strip 5 to pass through is formed in the card slot 8, so that the card strip 5 can be pulled out of the first groove body. The combined use of multiple limiting layers 7 can endow it with a password function;

[0036] The buckle structure of this application is applied to the paper box. The user needs to pull the limiting layer 7 to a preset position. Multiple limiting layers 7 need to be in the preset position at the same time to pull out the inserting layer 4. Only after the inserting layer 4 is pulled out can the cover body 12 be separated from the box body 11, making the paper box have a password unlocking function and effectively preventing children from casually opening the package and eating the medicine by mistake.

[0037] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
