Detailed implementation manners

[0022] The present utility model will now be described more fully hereinafter with reference to the accompanying drawings, in which the currently preferred embodiments of the present utility model are shown. However, the present utility model can be implemented in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided for thoroughness and completeness and fully convey the scope of the present utility model to those skilled in the art.

[0023] The following will be combined with Figures 1-6 and examples to further illustrate the present invention.

[0024] Example 1

[0025] Traditional furnace packaging mainly relies on EPS materials. Its advantage is that it can provide a formed structure that highly conforms to the appearance of product A through mold customization, providing transportation protection for heavy furnaces over 15 kilograms. However, with the increasingly strict global environmental protection standards, customers have clearly prohibited the use of EPS packaging; aiming at the pain points of heavy furnace weight and poor protection of the outer shell during logistics, as well as the performance limitations of conventional environmentally friendly packaging materials such as honeycomb boards and corrugated cardboard in heavy protection scenarios, the present utility model proposes an origami packaging box for furnaces, which improves the protection of furnace product A through innovative structural design, taking into account environmental protection requirements and transportation safety. Specifically, it includes: outer box B, support members and side limiting members. The outer box B is a rectangular structure, with a sealing part at the upper part. Product A is placed vertically in the outer box B. The support members are in a horizontally placed "day" - shaped structure, with card slots provided on both sides of the support members. The side limiting members have slotted openings, and the side limiting members are inserted into the card slots of the support members through the slotted openings.

[0026] It is worth mentioning that the support member includes a support base member and a middle reinforcement member. The support base member includes a lower support base B1 and an upper support base B5. The middle reinforcement member includes a lower paper card B2 and an upper paper card B6. Both the lower support base B1 and the upper support base B5 are folded from cardboard. After the cardboard is folded into a rectangular shape with open sides, the two sides of the cardboard are folded upward and closed together from the midpoint of the bottom, forming a reinforcing rib in the middle. Both the lower support base B1 and the upper support base B5 are in a horizontally placed "日" - shaped structure. They respectively enclose with the corresponding reinforcing ribs to form two cavities. Considering the characteristic that the center of gravity of product A is biased towards the bottom, the height of the lower support base B1 is set higher than that of the upper support base B5. By increasing the height of the lower support base B1, its bearing capacity is strengthened, forming a differential support adapted to the center - of - gravity distribution. In the middle of the side close to product A of the lower support base B1 and the upper support base B5, limiting grooves are respectively opened at the positions of their reinforcing ribs. The limiting groove of the lower support base B1 and the bottom reinforcing rib enclose to form a bottom cavity, and the limiting groove of the upper support base B5 and the top reinforcing rib enclose to form a top cavity. The bottom cavity of the lower support base B1 closely fits into the bottom contour of product A, and the top cavity of the upper support base B5 correspondingly fits into the top structure of product A, realizing a two - way stable assembly up and down. Further, three card slots are opened on the reinforcing ribs of both the lower support base B1 and the upper support base B5, and the depth of the card slots on the reinforcing rib of the lower support base B1 is greater than that of the upper support base B5. Embedding grooves adapted to the depth of the corresponding card slots are respectively provided at the center of the bottom of the three lower paper cards B2 and the center of the top of the upper paper card B6, realizing the locking connection between the paper cards and the reinforcing ribs. The upper parts of the three lower paper cards B2 and the bottom parts of the upper paper card B6 are respectively designed with bottom support parts and top support parts that fit the bottom and top contours of product A. The three lower paper cards B2 and the upper paper card B6 are respectively inserted into the card slots of the reinforcing ribs of the lower support base B1 and the upper support base B5 in a "川" - shaped layout, forming a vertically symmetric support structure. By means of the longitudinal "川" - shaped layout, the vertical load acting on the upper and lower support bases B1 by product A is evenly distributed. The lengths of the three lower paper cards B2 and the three upper paper cards B6 are adapted to the inner diameters of the cavities of the lower support base B1 and the upper support base B5. After installation, they respectively closely adhere to the side walls of the upper support base B5 and the lower support base B1, which can effectively enhance the side - wall structural stiffness of the lower support base B1 and the upper support base B5 and inhibit the side - inward depression caused by force during transportation.

[0027] More notably, the side limiting component includes an upper card box component and a lower card box component. The upper card box component is divided into a first upper card box B7 and a second upper card box B8, and the lower card box component is divided into a first lower card box B3 and a second lower card box B4. Both the upper support B5 and the lower support B1 have double slots on the reinforcing ribs near product A. During assembly, the first lower card box B3 and the second upper card box B8 are inserted into the slots on both sides of the upper support B5, and the first lower card box B3 and the second lower card box B4 are inserted into the slots on both sides of the lower support B1. The first lower card box B3 and the second lower card box B4, as well as the first upper card box B7 and the second upper card box B8, are all rectangular hollow structures that match the dimensions of the slots. They have a notch in the middle, which is used to lock the reinforcing ribs during installation. The side facing the middle of the cavity of the lower support B1 and the upper support B5 is designed with double-layer cardboard, which can effectively distribute the lateral load and enhance the resistance to deformation. At the same time, the embedding of the upper and lower card box components further strengthens the structural rigidity of the side edges of the upper and lower support B1, forming multi-dimensional support for the side walls of the support.

[0028] The above is only the first state of this utility model. In logistics and transportation scenarios, to improve the utilization rate of storage space, heater products A are often stacked or placed horizontally in various ways. Different placement methods will cause changes in the direction and point of force on the outer box B of product A, thereby affecting the load-bearing and protective performance of the carton structure. Traditional carton design usually strengthens the bottom support structure for the axial placement of product A to improve the vertical load-bearing capacity. However, if product A is changed from axial placement to horizontal placement or from side axial placement in actual transportation, the original unidirectional support structure for the bottom of product A (such as bottom reinforcing ribs, load-bearing partitions) will not be able to adapt to the new stress scenario, making it easy for the carton structure to have insufficient lateral support for product A. When the weight of product A exceeds the structural load-bearing threshold, it is easy to cause lateral deformation or damage to the carton, resulting in protection failure. In this regard, this embodiment also proposes a second state to deal with the above problems. (See the second state for details.) Figure 6 As can be seen, with the lower support B1 and upper support B5 on both sides and product A placed horizontally, in this state, the lower support B1 and upper support B5 are symmetrically arranged at both ends of product A. When product A is placed horizontally, the weight of product A is evenly supported by the large force-bearing area and multi-point support structure. The bottom support of the three sets of lower paper cards B2 is precisely fitted with the bottom contour of product A, and the upper support of the three sets of upper paper cards B6 is tightly engaged with the top contour of product A, forming multi-point support on both sides of the middle of product A. At the same time, the limiting groove of lower support B1 and the bottom reinforcing rib, and the limiting groove of upper support B5 and the top reinforcing rib respectively enclose the bottom and top cavities, which, together with the three sets of paper card support structures, make product A stably suspended inside the outer box B, forming a buffer layer between product A and the wall of the outer box B, effectively isolating external impacts and evenly distributing loads in all directions.

[0029] The above is only the second state of this utility model. To address the aforementioned problem, this embodiment also proposes a third state, namely, the side of the product A originally placed axially as the bottom state. (See attached document.) Figure 6 It can be seen that the lower support B1 and the upper support B5 are symmetrically arranged at both ends along the axis of product A. When product A is placed vertically, although the initial force-bearing area on both sides of the support axis is relatively limited, the support strength is effectively compensated by adding upper and lower card boxes (including the first upper card box B7, the second upper card box B8, the first lower card box B3, and the second lower card box B4) on both sides. The card box is snapped onto the side of the support near product A. Its rectangular hollow structure and the cavity of the support form a cross-shaped support frame, which significantly increases the contact force points. At the same time, the notched structure in the middle of the card box tightly engages with the reinforcing rib of the support, forming a mechanical lock. This not only strengthens the connection rigidity between the support and the reinforcing rib, but also evenly distributes the axial support force on both sides of product A to the entire support frame through the enclosure structure of the bottom cavity and the top cavity, ensuring balanced load bearing in all directions in the vertical state.

[0030] The specific working principle of this embodiment is as follows: When packing product A, the staff first inserts the three sets of upper paper cards B6 and lower paper cards B2 into the three slots of the reinforcing ribs of the upper and lower support B1 respectively. Then, the first and second lower card boxes B4 are inserted into the strip slots on both sides of the lower support B1, and the first and second upper card boxes B8 are inserted into the strip slots on the side of the upper support B5. The card boxes are locked together by the notch in the middle of the card box to fasten the reinforcing ribs of the support. After the assembly is completed, the lower support B1 is placed at the bottom of the outer box B so that the bottom of product A is precisely attached to the bottom support of the lower support B1. Then, the upper support of the upper support B5 is fastened to the top outline of product A. Finally, the outer box B is sealed.

[0031] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
