[0017] The technical scheme of the utility model will be described clearly and completely in combination with the drawings. Obviously, the described embodiments are part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all the other embodiments obtained by the person skilled in the art without creative labor belong to the protection scope of the utility model.

[0018] Please refer to Figure 1 , and combine Figure 2 , Figure 3 , Figure 4 and Figure 5The utility model discloses a packing box with moistureproof structure, including outer box 1 and the inner box 2 of embedding setting in outer box 1, and the opening 21 for article taking and placing is formed to the open top of inner box 2, the top cover 10 is established on outer box 1 through the rotary connection structure, and the top cover 10 is used to cover the opening 21, the outer surface of inner box 2 is covered with moistureproof pearl wool layer 201, and the surface of moistureproof pearl wool layer 201 is covered with flannel 202, and the inside surface of top cover is covered with aluminium foil composite film layer 101 for preventing moisture. Accordingly, the inner box 2 that can be separated with outer box 1 is additionally arranged, and the inner box 2 is covered with moistureproof pearl wool layer 201, which can be used for placing articles and preventing moisture. Moreover, the top cover 10 is rotatably connected to the outer box 1, and the inner wall of the top cover 10 is provided with an aluminium foil composite film layer 101 for preventing moisture, which further improves the moisture-proof performance of the packing box. When the packing box is not used for a long time or placed in a humid place, the articles placed in the inner box are also less likely to be damaged by moisture.

[0019] Further, the top cover 10 includes a left cover 11 and a right cover 12 rotatably connected to the two sides of the outer box 1, respectively. The top inner wall of the right cover 12 has a limiting groove 121 extending from the periphery to the center thereof, and the top of the limiting groove 121 is provided with a groove 122. The top of the left cover 11 is provided with a spring piece 111 extending from the center to the periphery thereof. The spring piece 111 extends outwardly along the tongue 1103 which can be movably connected to the limiting groove 121. The top of the tongue 1103 is formed with a protruding structure 1104 corresponding to the groove 122. When the left cover 11 and the right cover 12 cover the opening 21, the protruding structure 1104 is located in the groove 122. Accordingly, the left cover 11 and the right cover 12 can be turned to close or open the opening 21, which is simple in structure and has good comprehensive performance in displaying and protecting articles.

[0020] Further, one end of the spring piece 111 is a fixed end 1102, and the other end is a free end 1101. The fixed end 1102 is fixedly connected to the left cover 11. The upper surface of the free end 1101 is provided with a slot 1105 for placing a finger. Accordingly, when the left cover 11 and the right cover 12 are turned to close them, the finger can apply a downward pressure to the free end 1101 of the spring piece 111 in the slot 1105, so that the tongue 1103 can smoothly extend into the limiting groove 121 of the right cover 12, and the protruding structure 1104 is inserted into the groove 122. Similarly, the downward pressure applied to the free end 1101 of the spring piece 111 can make the tongue 1103 smoothly separate from the limiting groove 121 of the right cover 12. When the opening 21 is covered, the limiting groove 121 prevents the tongue 1103 from shaking left and right, thereby ensuring the firmness and rationality of the connection between the left cover 11 and the right cover 12.

[0021] Further, the bottom of the left cover 11 and the bottom of the right cover 12 are rotatably connected with the outer box 1 through a rotating shaft 13. Accordingly, the rotating connection structure of the present application adopts the rotating shaft 13, which further simplifies the structure of the packaging box, improves the practicability, and reduces the production cost.

[0022] Further, the left cover 11 and the right cover 12 are upwardly or downwardly rotatable relative to the outer box 1 with the rotating shaft 13 as the axis.

[0023] The above embodiments only express several implementation manners of the present application, and the description is relatively specific and detailed, but it should not be understood as the limitation of the patent scope of the present application. It should be pointed out that, for ordinary skilled in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which all belong to the protection scope of the present application. Therefore, the protection scope of the present application patent should be based on the appended claims.
