Detailed Description

In order to more clearly illustrate the embodiments of the present invention and/or the technical solutions in the prior art, the following description will explain specific embodiments of the present invention with reference to the accompanying drawings. It is obvious that the drawings in the following description are only some examples of the invention, and that for a person skilled in the art, other drawings and embodiments can be derived from them without inventive effort. In addition, the term "orientation" merely indicates a relative positional relationship between the respective members, not an absolute positional relationship.

As shown in fig. 1, 2 and 3, the present invention provides an automatically expandable double-layered packing box, which comprises a first cigarette containing box 1, a second cigarette containing box 2, a connecting box 3 fixedly connected with one end of the first cigarette containing box 1, and a limiting device 4 arranged in the connecting box 3. In order to make the present invention have a more robust structure to realize the protection of cigarettes and the reuse of the cigarette case, the first cigarette containing case 1, the second cigarette containing case 2, and the first cigarette containing case 1 and the connecting case 3 are preferably made of plastic or alloy.

The first cigarette containing box 1 is internally provided with a first cigarette containing plate 12 and a first contraction groove 13 for the first cigarette containing plate 12 to extend out or retract, the first cigarette containing plate 12 is connected with a telescopic spring 131 arranged at the bottom of the first contraction groove 13, and then the first contraction groove 13 is pushed out of one side part of the first cigarette containing plate 12, which is provided with a first cigarette containing cavity 121, through the telescopic spring 131. The first cigarette case 1 is provided with a guide rail 11 at the opening of the first contraction groove 13 for the second cigarette case 2 to slide, and the second cigarette case 2 is connected with the guide rail 11 in a sliding way through a sliding fixing strip 23 arranged at two sides. Wherein, one side of the first cigarette containing plate 12 far away from the connecting box 3 is provided with a first inclined wall 122, and the first inclined wall 122 is matched with the first cigarette containing box 1 and the second cigarette containing box 2 through the guide rail 11 and the first inclined wall 122, so that when the second cigarette containing box 2 is folded under the action of external force, pressure in the direction of the bottom of the first shrinkage groove 13 can be applied to the first inclined wall 122, and the first cigarette containing plate 12 is further pushed to shrink into the first shrinkage groove 13. When the second cigarette case 2 slides along the guide rail 11 to abut against the connecting box 3, the user can drive the limiting device to fix the first cigarette case 1, the second cigarette case 2 and the connecting box 3 to the designated positions, so that the cigarettes are folded.

As shown in fig. 2, 4 and 5, a second cigarette containing cavity 21 is arranged in the second cigarette containing box 2, and a turnover cover 22 which can be turned over is arranged on one side of the second cigarette containing box 2 close to the second cigarette containing cavity 21, so that the cigarettes in the second cigarette containing cavity 21 can be prevented from directly contacting the outside. The limiting device 4 comprises a first rotating rod 412, a first overturning plate 411 connected with the rod body of the first rotating rod 412, a limiting cover plate 41 fixedly connected with one end of the first overturning plate 411, and a first gear 413 arranged at two ends of the first rotating rod 412, and the limiting device 4 further comprises a second rotating rod 421, a shifting overturning plate 42 connected with the rod body of the second rotating rod 421, and a second gear 422 arranged at two ends of the second rotating rod 421; the first gear 413 is meshed with the second gear 422, when the second cigarette containing box 2 abuts against the connecting box 3, the second gear can toggle the turning plate 42 to turn towards the direction away from the limit cover plate 41, so as to drive the second gear 422 to rotate, and the first gear 413 is matched to drive the limit cover plate 41 to turn towards the side away from the first cigarette containing cavity 121 of the second cigarette containing box 2, so that the turning cover 22 can be prevented from being opened when bumped, and the cigarettes in the second cigarette containing cavity 21 can be prevented from falling out. If the user needs to take out the cigarette in the second cigarette accommodating cavity, the user only needs to toggle the toggle turnover plate 42 to the direction close to the limit cover plate 41 to flip until the limit cover plate 41 is separated from the flip cover 22.

As shown in fig. 1, 2, 4, 5 and 7, the limiting device 4 further includes a third rotating rod 431, limiting hooks 43 disposed at two ends of the third rotating rod 431, and a third gear 432 disposed at a position where a rod of the third rotating rod 431 is close to the limiting hooks 43, wherein the third gear 432 is engaged with the second rotating rod 421; one side of the second cigarette containing box 2 close to the limiting device 4 is provided with a limiting buckle 24 corresponding to the limiting hook 43, when the second cigarette containing box 2 abuts against the connecting box 3, the turning plate 42 can be toggled to turn towards the direction far away from the limiting cover plate 41, so as to drive the second gear 422 to rotate, and the third gear 432 can be matched to drive the limiting hook 43 to rotate along the axis of the third rotating rod 431 to be clamped with the limiting buckle 24. Wherein, a limit groove 31 for the limit buckle 24 to pass in and out is arranged in the connecting box 3.

The number of teeth of the first gear 413 is the same as that of the second gear 422, and the number of teeth of the third gear 432 is greater than that of the first gear 413. When the toggle turning plate 42 is toggled to turn towards the direction close to the limit cover plate 41, the first turning plate 411 is firstly driven by the second gear 422 to turn over until the limit cover plate 41 is separated from the turning cover 22, so that the cigarettes in the second cigarette containing cavity 21 of the second cigarette containing box 2 can be conveniently taken out. When the toggle turning plate 42 is toggled to turn to a direction close to the limit cover plate 41 to a certain angle, the limit buckle 24 and the limit hook 43 are separated, so that the second cigarette containing box 2 can slide along the guide rail 11 to the first cigarette containing plate 12 and can be popped out from the first shrinkage groove 13, and the cigarettes in the second cigarette containing box 2 can be conveniently taken and placed.

As shown in fig. 6 and 7, a second movable opening 33 for moving the toggle turnover plate 42 and a first movable opening 32 for moving the first turnover plate 411 are provided in the connection box 3. The connecting box 3 is provided with a stop block 34 at a side of the second movable opening 33 away from the first rotating rod 412, so as to prevent the user from accidentally touching the toggle flip 42 when carrying the cigarette box, which causes the flip cover 22 of the second cigarette containing box 2 to be flipped and causes the cigarettes to fall off, and also prevent the toggle flip 42 from being excessively squeezed by external force and damaged.

The foregoing is a more detailed description of the invention in connection with specific preferred embodiments and it is not intended that the invention be limited to these specific details. For those skilled in the art to which the invention pertains, several simple deductions or substitutions can be made without departing from the spirit of the invention, and all shall be considered as belonging to the protection scope of the invention.
