[0001] The utility model relates to the technical field of packaging boxes with protective structures, in particular to a packaging box with a protective structure. Background Art

[0002] The packaging box is mainly for the convenience of transportation, loading and unloading and storage. Generally, wooden boxes and corrugated wood pallets are used, and tin drums or galvanized iron drums are also used. The standard used is GB / T 7284-1998 frame wooden box national standard drafting unit.

[0003] However, when using existing packaging boxes, when the top cover of most packaging boxes is closed and the packaging box is subjected to external impact, a gap is easily formed between the top cover and the packaging box, resulting in reduced sealing performance. In addition, when the packaging box needs to be ventilated, most of the ventilation holes are opened. As a result, when ventilation is not required, the ventilation holes need to be blocked with adhesive tape, which reduces the use range of the packaging box.

[0004] Therefore, the present application provides a packaging box with a protective structure to meet the needs. Utility Model Content

[0005] The purpose of the present utility model is to solve the problems existing in the above-mentioned background technology and to propose a packaging box with a protective structure.

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise" and the like to indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0026] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4 The embodiment of the present invention provides a packaging box with a protective structure, which includes: a packaging box body 1, an arc-shaped piece 102 fixedly connected to the upper part of the outer side of the packaging box body 1, a top cover 2 nested on the upper part of the packaging box body 1, a card slot 201 is provided around the inner wall of the top cover 2, the card slot 201 and the arc-shaped piece 102 are matched with each other, the card slot 201 is an inwardly concave arc surface, a groove 3 is provided on the right side of the packaging box body 1, and a sponge 103 is filled in the gap between the arc-shaped piece 102 and the packaging box body 1, and the arc-shaped piece 102 is made of rubber;

[0027] When the top cover 2 and the packaging box body 1 are closed, the inner wall of the top cover 2 will squeeze the arc piece 102, and the arc piece 102 will fit tightly into the sealing groove 202 around the inner wall of the top cover 2 after being deformed by the force, so that the arc piece 102 fits tightly into the sealing groove 202 and seals, thereby increasing the sealing performance after the top cover 2 and the packaging box body 1 are closed. At the same time, when the arc piece 102 is squeezed by the inner wall of the top cover 2, the arc piece 102 will be deformed and will always be stuck in the sealing groove 202 through the elastic force of the sponge 103, so that it is not easy to produce a gap when the arc piece 102 fits the sealing groove 202, thereby increasing the sealing performance.

[0028] In this embodiment, Figure 2-Figure 4 As shown;

[0029] The bottom of the packaging box body 1 is fixedly connected to the base 101, and the top of the top cover 2 is provided with a card slot 201. The card slot 201 and the base 101 are matched.

[0030] When multiple packaging box bodies 1 need to be stacked for transportation, when a packaging box body 1 is stacked on top of another packaging box body 1, the base 101 around the bottom of the packaging box body 1 can be inserted into the card slot 201 of the top cover 2 of the other packaging box body 1, so that the two packaging box bodies 1 have support and effectively prevent tilting and collapsing;

[0031] The groove 3 is movably connected to a movable disk 301. Second air holes 303 are provided at both upper and lower ends of the left side of the groove 3. First air holes 302 are provided at both upper and lower ends of the movable disk 301.

[0032] When ventilation is required inside the packaging box body 1, the user can manually rotate the movable disk 301 so that the first ventilation hole 302 and the second ventilation hole 303 are at the same horizontal plane, so that outside air can enter the packaging box body 1 through the first ventilation hole 302 and the second ventilation hole 303 for ventilation. When ventilation is not required, the user can rotate the movable disk 301 again so that the first ventilation hole 302 and the second ventilation hole 303 are staggered, so that outside air is not easy to enter the packaging box body 1 through the first ventilation hole 302 and the second ventilation hole 303.

[0033] The groove 3 is located on the side of the second vent hole 303 close to the movable disk 301 and is embedded with a sealing ring 304. A spring 305 is fixedly connected between the sealing ring 304 and the groove 3. The cross section of the sealing ring 304 is in a "concave" shape with the side away from the spring 305 tilted towards the side away from the spring 305.

[0034] When the second air hole 303 is staggered with the first air hole 302, the sealing ring 304 will always be tightly attached to the left side of the movable disk 301 through the elastic force of the spring 305, so that the second air hole 303 is sealed by the sealing ring 304, and the concave shape of the sealing ring 304 has double sealing when it fits the movable disk 301, thereby further increasing the sealing of the second air hole 303 and the first air hole 302 after they are staggered.
