Detailed implementation manners

[0028] The present utility model will be further described below in conjunction with the drawings and specific embodiments, so that those skilled in the art can better understand the present utility model and be able to implement it, but the embodiments cited are not intended to limit the present utility model.

[0029] Referring to Figures 1-3 as shown, the present utility model provides a double - door lifting packaging box, comprising:

[0030] A box body part 20, which comprises a first box body 21 and a second box body 22 that is slidably engaged with the first box body 21;

[0031] An outer shell part 30, which comprises a pair of box covers 31 arranged on both sides of the first box body 21, and one end of the box cover 31 is rotatably connected to the first box body 21 through a folding line 40;

[0032] A pulling part 50, which comprises a pair of pulling belts 51 arranged on both sides of the first box body 21; the pulling belt 51 passes through the first box body 21, and one end thereof is connected to the second box body 22, and the other end is connected to the box cover 31;

[0033] In the closed state of the packaging box, the second box body 22 is embedded inside the first box body 21, and at the same time, the box covers 31 on both sides are tightly closed with the first box body 21;

[0034] In the open state of the packaging box, the box covers 31 on both sides are in an open state, and at the same time, under the action of the pulling belt 51, the second box body 22 at least partially extends out of the first box body 21.

[0035] Specifically, the utility model mainly consists of three parts: a box body part 20, a housing part 30, and a pulling part 50, aiming to solve the problem of inconvenient operation when taking objects from traditional packaging boxes; through the double-door structure formed by the box cover 31 of the housing part 30 and the lifting structure formed between the pulling belt 51 and the lifting box body, the convenient and efficient function of storing and retrieving items is realized. Among them,

[0036] The box body part 20 includes a first box body 21 and a second box body 22 that is slidably matched with the first box body 21; the first box body 21 constitutes the main structure of the packaging box, and at least one accommodation cavity for accommodating the second box body 22 is provided inside it; while the second box body 22 is used to support or place items, and its outer wall is slidably matched with the inner wall of the accommodation cavity, so that the second box body 22 can slide up and down inside the first box body 21.

[0037] The housing part 30 includes a pair of box covers 31 provided on both sides of the first box body 21; one ends of the box covers 31 on both sides are respectively rotatably connected to the first box body 21 through folding lines 40, so that the box covers 31 can rotate and open and close relative to the first box body 21; in the closed state of the packaging box, the box covers 31 on both sides are tightly closed on both sides of the first box body 21, forming a complete enclosed space to protect the internal items from the outside.

[0038] The pulling part 50 is the key component of the double-door lifting structure in the utility model, and it includes a pair of pulling belts 51 provided on both sides of the first box body 21; the pulling belts 51 pass through specific positions of the first box body 21 and are respectively connected to the second box body 22 and the box cover 31; in the closed state of the packaging box, the pulling belts 51 are in a relaxed state (that is, usually do not apply force to the second box body 22), which does not affect the closing of the box cover 31 and the embedding of the second box body 22; however, when opening the packaging box, as the box cover 31 opens, the pulling belts 51 are gradually tightened, and then drive the second box body 22 to slide upward, so that the second box body 22 at least partially extends out of the first box body 21, so as to push out or expose the object supported or placed on the second box body 22; through the above structure, the opening and closing action of the box cover 31 is integrated with the lifting of driving the second box body 22, which not only realizes the convenient storage and retrieval of items, but also enhances the visual effect of displaying stored objects and improves the user experience.

[0039] In the closed state of the packaging box, the second box body 22 is completely embedded inside the first box body 21 and is protected by the housing part 30, effectively preventing external factors such as dust and moisture from damaging the items; at the same time, the box covers 31 on both sides are tightly closed with the first box body 21, ensuring the sealing and aesthetics of the packaging box.

[0040] When it is necessary to open the packaging box to take out items, the user only needs to gently open the box lids 31 on both sides. As the box lids 31 open, the pulling belt 51 is gradually tightened and drives the second box body 22 to rise, so that the items are revealed, facilitating the user to quickly and accurately take out the required items. Thus, the utility model can not only improve the convenience of taking out items, but also enhance the user experience.

[0041] Referring to Figure 4 As shown, an upwardly open receiving cavity is provided in the first box body 21, and the outer wall of the second box body 22 is slidably engaged with the inner wall of the receiving cavity. A through hole 211 for the pulling belt 51 to pass through is provided on one side of the receiving cavity close to the box lid 31.

[0042] Specifically, the size and shape of the receiving cavity in the first box body 21 need to accurately adapt to the external dimensions of the second box body 22 to ensure that the second box body 22 can smoothly slide up and down in the receiving cavity. The opening of the receiving cavity faces upward, which is convenient for the installation, removal, and lifting of the second box body 22, and thus the objects on the second box body 22 are convenient to be put in, taken out, and displayed. The outer wall of the second box body 22 is closely fitted with the inner wall of the receiving cavity, but with an appropriate gap to ensure that the second box body 22 can smoothly slide up and down without skewing during lifting. The position and size of the through hole 211 need to accurately adapt to the size and displacement of the pulling belt 51 to ensure that the through hole 211 correctly becomes the sliding fulcrum of the pulling belt 51, guaranteeing the stability and smoothness of the pulling belt 51 during the process of driving the second box body 22 to lift and slide.

[0043] Referring to Figure 1 As shown, one end of the pulling belt 51 passes through the through hole 211 and is connected to the side wall or bottom of the second box body 22.

[0044] Specifically, one end of the pulling belt 51 passing through the through hole 211 and extending into the first box body 21 is firmly connected to the second box body 22 by means of an adhesive, a preset connecting piece, etc. The connecting position is usually set on the side wall or bottom of the second box body 22, and the specific connecting method and setting position can be flexibly adjusted according to factors such as the mass of the supported object, the size and mass of the box body, etc. The pulling belt 51 is usually a flexible belt with strong durability to withstand multiple opening and closing operations without being easily damaged.

[0045] In a specific embodiment, a sliding damping is provided between the outer wall of the second box body 22 and the inner wall of the receiving cavity.

[0046] Specifically, in order to ensure the stability and smoothness of the sliding of the second box body 22, a sliding damping structure or material can be provided between the inner wall of the receiving cavity and the outer wall of the second box body 22 to form an appropriate frictional resistance between the two to prevent the second box body 22 from shifting during the sliding process.

[0047] Reference Figure 1 As shown, a bracket 221 is provided on the second box body 22. Usually, the object to be mainly stored and displayed is placed on the bracket 221, so that the object can be well protected by the box body part 20 on the one hand, and can be lifted out and displayed immediately when the double doors (the lid 31 part) are opened on the other hand.

[0048] Reference Figures 1-2 As shown, at least one drawer box 212 is further provided on the first box body 21, and the drawer box 212 has a pulling direction different from the opening direction of the lid 31.

[0049] Specifically, in this embodiment, the box body part 20 not only stores objects through the second box body 22, but also can store objects through other drawer boxes 212 provided in the first box body 21 to increase the storage capacity; the setting feature of the drawer box 212 is that its pulling direction is different from the opening direction of the lid 31, so that its pulling and opening / closing will not interfere with each other, improving the independence of the two storage spaces, thereby enhancing the user's convenience; in some embodiments, the first box body 21 adopts a multi-stage box body structure, that is, the accommodating cavity part for accommodating the second box body 22 and the box body part 20 for accommodating the drawer box 212 are hierarchically arranged to further enhance the differentiation and independence.

[0050] In a specific embodiment, a handle part 2121 is provided on the drawer box 212. The handle part 2121 usually adopts a rigid handle or a flexible ribbon and is provided in the middle of the surface of the drawer box 212.

[0051] Reference Figure 1 As shown, a slope 311 is provided on the lid 31 near the folding line 40; in the closed state of the packaging box, the slopes 311 of the two lids 31 are closed and limit the drawer box 212.

[0052] Specifically, when the packaging box is closed, the slopes 311 of the two lids 31 are attached to each other to form a natural limiting structure, preventing the drawer box 212 from being removed or pulled out accidentally and increasing the safety of the packaging box; in addition, the slope 311 also provides a function of guiding the correct alignment and closing of the lid 31, that is, the user only needs to fold the two lids 31 along the folding line 40 so that the ends of the slopes 311 of the two lids 31 (the side away from the folding line 40) are aligned and attached to complete the reset; in addition, the setting of the slope 311 can also present a more smooth and concise line when the packaging box is closed, thereby enhancing the overall aesthetics.

[0053] In some embodiments, in the closed state of the packaging box, the pulling part 2121 and the outer shell part 30 form a locking structure; a locking structure can be formed between the pulling part 2121 and the outer shell part 30 to further enhance the stability of the box body state in the closed state of the packaging box; in one specific embodiment, the flexible pulling part 2121 can be turned up and hooked with the protruding locking hook provided on the side of the box cover 31 to form a locking structure that can be opened and closed repeatedly.

[0054] Obviously, the above embodiments are merely examples given for clear illustration and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present utility model.
