DETAILED DESCRIPTION

[0047] Please refer to the attached Figure 1 - attachedFigure 14 Embodiment 1:

[0049] A rotary packaging box comprises a box body, a locking mechanism 3 and an elastic member 4.

[0050] As shown in Figures 1-2 , the box body comprises an outer box 1 and an inner box 2, the outer box 1 is a cylindrical structure with an upper opening, and the inner box 2 is a hollow box that fits into the inner cavity of the outer box 1 and can be used to place goods. The inner box 2 is movably arranged in the inner cavity of the outer box 1 and can freely move up and down. The upper part of the inner box 2 is open and provided with a detachable box cover 201, and a circle of inward recesses is formed on the upper peripheral wall of the inner box 2, and the inner wall of the box cover 201 can be matched and embedded with the upper peripheral wall of the inner box 2.

[0051] The elastic member 4 is a supporting spring arranged between the inner bottom of the outer box 1 and the outer bottom of the inner box 2, which can support the inner box 2 loaded with goods to lift up when not subjected to external force, so that the upper part of the inner box 2 protrudes out of the upper opening of the outer box 1, facilitating the disassembly of the box cover 201.

[0052] The locking mechanism 3 is arranged between the inner bottom wall of the outer box 1 and the outer bottom wall of the inner box 2 and located at the axis of the inner cavity of the outer box 1, which specifically comprises a locking head 30 and a clamping head 302.

[0053] As shown in Figure 3 and Figure 5 , the lower part of the locking head 301 is provided with a horizontally extending base and is fixedly arranged at the center of the inner bottom of the outer box 1, the center of the base extends upward to form a cylindrical structure, and the upper end of the cylinder extends radially to both sides to form a pair of symmetrically arranged clamping columns 3011.

[0054] The upper part of the clamping head 302 is provided with a horizontally extending platform and is fixedly arranged at the center of the outer bottom of the inner box 2, the lower side of the platform of the clamping head 302 is provided with a vertically extending annular wall surface, the bottom of the annular wall surface extends inward on both sides to form two pairs of limit plates 3021 symmetrically arranged with respect to the center of the axis, the end of the four limit plates 3021 extends vertically upward by a distance to form a rectangular region limit cavity 3023 (the region shown by the dashed line box), one pair of limit plates 3021 symmetrically arranged with respect to the center of the axis is provided with a protruding limit protrusion 3022 on one side of the limit cavity 3023, and the horizontal and vertical distance enclosed by the two limit protrusions 3022 is shorter than the horizontal radial width of the clamping column 3011. Figure 7

[0055] The principle of buckling and unlocking:

[0056] When buckling, the inner box 2 is pressed downward to overcome the elastic force of the supporting spring, and the clamping head 302 is translated to approach the locking head 301 at the bottom, as shown in Figure 3 and​Figure 4 As shown, the downward pressing to the clamping post 3011 extends into and passes through the limiting cavity 3023, when the clamping post 3011 touches the lower side of the limiting protrusion 3022 in the process of extending into the limiting cavity 3023, the limiting plate 3021 limiting the limiting protrusion 3022 will be expanded to the both sides, and then the clamping post 3011 will pass the limiting protrusion 3022, at this time, the pressing force is removed, under the action of the expansion force of the supporting spring, the clamping head 302 and the locking head 301 are away from each other, the lower side of the clamping post 3011 and the upper side of the limiting protrusion 3022 are clamped and locked, and the effect that the inner box 2 is accommodated in the outer box 1 is realized.

[0057] When unlocking, a horizontal rotating force is applied to the inner box 2, so that the inner box 2 is deflected by a certain angle relative to the outer box 1, as shown in Figure 5 and Figure 6 As shown, the clamping head 302 rotates with the inner box 2, and the clamping head 302 is deflected relative to the locking head 301 to the side away from the limiting protrusion 3022, and the clamping post 3011 abuts and pushes the limiting plate 3021 not limiting the limiting protrusion 3022 when rotating, so that the limiting plate 3021 is deformed and bent, and the limiting plate 3021 on the side limiting the limiting protrusion 3022 is avoided from the limiting protrusion 3022, and under the driving of the expansion elastic force of the supporting spring, the clamping post 3011 can exit the limiting cavity 3023, so that the clamping head 302 and the locking head 301 are unlocked, and the inner box 2 is popped out of the outer box 1.

[0058] Specific embodiment two: on the basis of the specific embodiment one, as shown in Figures 8-14 Another specific structure of the locking mechanism 3 is provided.

[0059] As shown in Figure 14 The clamping post 3011 on each side of the locking head 301 is provided with an avoidance groove 3012 recessed along the horizontal radial direction on one side, and the avoidance grooves 3012 on the two clamping posts 3011 are centrally symmetrically distributed relative to the axis of the locking head 301.

[0060] As shown in Figure 12 One end of one of the two groups of limiting plates 3021 on the clamping head 302 extends vertically upward for a distance, and the other group of limiting plates 3021 extends obliquely to one side of the limiting cavity 3023 to form an oblique limiting plate 3024, the oblique end of the oblique limiting plate 3024 extends to the horizontal middle position of the clamping head 302, and in particular, the end of the oblique limiting plate 3024 is cut at an angle near the axis of the clamping head 302 to form an avoidance bevel 3025.

[0061] The buckling and unlocking principle is as follows:

[0062] When buckling, as shown in Figure 8 and Figure 9As shown, under the action of pressing pressure, the locking pin 3011 extends into and passes through the limiting cavity 3023, expands and passes over the limiting plates 3021 and the inclined limiting plate 3024 on both sides. At this time, the pressing pressure is removed, the locking head 302 and the locking head 301 move away from each other, and the lower side of the locking pin 3011 abuts against the top of the inclined limiting plate 3024 to lock, so as to achieve the effect of storing the inner box 2 in the outer box 1.

[0063] When unlocking, such as Figure 10 and Figure 11 As shown, when the locking pin 3011 rotates, one side abuts against the pushing limit plate 3021, causing the limit plate 3021 to deform and bend. The clearance groove 3012 on the other side of the locking pin 3011, after deflection, matches the clearance angle 3025 on the corresponding inclined limit plate 3024. Driven by the expansion force of the support spring, the locking pin 3011 can exit the limiting cavity 3023, causing the locking head 302 to disengage from the locking head 301, and the inner box 2 pops out of the outer box 1. Through the cooperation of the clearance groove 3012 and the clearance angle 3025, the inner box 2 can be unlocked with a smaller deflection angle, achieving a more convenient unlocking process. Specific Implementation Example 3:

[0065] Based on specific embodiment one and specific embodiment two, such as Figures 15-20 As shown, another specific structural form of the locking mechanism 3 is provided.

[0066] like Figure 19 As shown, the snap-fit ​​post 3011 has vertically downward protrusions at both ends, located on the lower left side of a single end of the snap-fit ​​post 3011, and the upper side of the snap-fit ​​post 3011 has an inclined chamfer. The horizontal length of the snap-fit ​​post 3011 is equal to the annular inner diameter of the snap-fit ​​connector 302.

[0067] like Figure 20 As shown, in one of the two sets of limiting plates 3021 on the snap-fit ​​connector 302, the two limiting plates 3021 symmetrical around the axis of the snap-fit ​​connector 302 each extend at an angle away from the axis of the snap-fit ​​connector 302, forming a vertical sidewall and creating an clearance angle 3025. In the field group of limiting plates 3021, the two limiting plates 3021 symmetrical around the axis of the snap-fit ​​connector 302 have a vertical rib in the middle of the side facing away from the clearance cavity 3023 to limit the deformation and bending ability. Specifically, the annular inner wall of the snap-fit ​​connector 302 has a limiting protrusion 3022 extending vertically upward along the central axis of the snap-fit ​​connector 302. There are two limiting protrusions 3022, corresponding to the two ends of the limiting cavity 3023 in the horizontal longitudinal direction. The annular inner wall of the limiting protrusion 3022 has a partition groove on both sides of the limiting protrusion 3022, so that the limiting protrusion 3022 has a certain deformation prevention capability.

[0068] The buckling and unlocking principles are as follows:

[0069] When buckling, under the action of the pressing force, the clamping head 302 approaches the locking head 301, the two ends of the clamping column 3011 expand outward to the annular inner wall of the limiting protrusion 3022 through the inclined chamfer, the annular inner wall of the limiting protrusion 3022 deforms and bends outward, and the clamping column 3011 as a whole extends into and passes through the limiting cavity 3023, as shown in Figure 15 and Figure 16 , the protrusions at the two ends of the clamping column 3011 abut against the limiting protrusion 3022. After abutting, as shown in Figure 16 , the protrusions of the clamping column 3011 abut against the side wall of the limiting protrusion 3022, and the clamping head 302 cannot rotate clockwise relative to the locking head 301, and similarly, since one set of limiting plates 3021 is limited in deformation and bending ability by the rib plate, the clamping head 302 cannot rotate counterclockwise relative to the locking head 301, thereby achieving the buckling and locking of the clamping head 302 and the locking head 301.

[0070] When unlocking, under the action of the pressing force, the clamping head 302 translates toward the locking head 301, the upper surface of the limiting protrusion 3022 moves to the lower surface of the protrusion of the clamping column 3011, at which time a rotating force is applied, as shown in Figure 18 and Figure 19 , the two limiting plates 3021 provided with the avoidance chamfer 3025 are abutted and pushed by the clamping column 3011, and are bent and deformed, so that the clamping head 302 can rotate clockwise relative to the locking head 301, and at the same time, as shown in Figure 18 , the protrusions of the clamping column 3011 are separated from the limiting protrusion 3022, and under the driving of the expansion elastic force of the supporting spring, the clamping column 3011 can exit the limiting cavity 3023, thereby achieving the unlocking of the clamping head 302 and the locking head 301.

[0071] The locking mechanism 3 is rotated and unlocked in the above manner, which limits the condition of rotating unlocking, and avoids the accidental opening of the packaging box due to accidental rotation during transportation and the like. Specific embodiment four:

[0073] On the basis of the above specific embodiments, a deflection limiting structure is added.

[0074] As shown in Figure 14 , limiting grooves 3013 extending along the axial direction of the locking head 301 are formed on both sides of the middle column of the locking head 301, as shown in Figure 12 and Figure 13 , two opposite deflection limiting plates 3026 are provided on the inner side of the annular wall surface of the clamping head 302, and the deflection limiting plates 3026 are located in the middle of the inner side of the annular wall surface and perpendicular to the limiting plates 3021.

[0075] As shown inFigure 9 As shown, when buckling, the clamping column 3011 is clamped with the upper end of the inclined limiting plate 3024, the end portions of the two deflection limiting plates 3026 extend into the limiting grooves 3013, and are respectively abutted against the side wall surfaces of the respective limiting grooves 3013 close to the inclined limiting plate 3024; when unlocking, the clearance groove 3012 of the clamping column 3011 matches the clearance bevel 3025 on the corresponding inclined limiting plate 3024 after deflection, and the end portions of the two deflection limiting plates 3026 are respectively abutted against the side wall surfaces of the respective limiting grooves 3013 close to the limiting plate 3021.

[0076] The deflection angle of the clamping head 302 relative to the locking head 301 is limited by the abutment of the deflection limiting plate 3026 and the limiting groove 3013, avoiding the situation that the clamping column 3011 and the limiting cavity 3023 are misaligned and the user cannot unlock.

[0077] The above only describes the preferred embodiments of the present application, and is not intended to limit the purpose, and various modifications, replacements, and substitutions within the spirit and principles of the design are within the protection scope of the present application.
