Description

Technical Field

[0001] The utility model relates to a compression-resistant and shock-absorbing packaging carton, which is particularly suitable for the compression-resistant and shock-absorbing packaging field of precision articles and fragile and vulnerable articles. Background Art

[0002] At present, the main material of packaging cartons is corrugated cardboard. When used in the packaging of precision items and fragile and vulnerable items, the usual protection method is to add foam shock-absorbing and cushioning materials in the box. Common foam shock-absorbing and cushioning materials include EPE foam board, EPS foam profile, and EPP foam material. The collapse of packaging boxes during logistics transportation and storage stacking is one of the main factors that cause damage to the goods in the box. In order to reduce the risk of collapse of packaging cartons, people usually use the following methods: increase the number of layers of corrugated cardboard and the thickness of single-layer materials. This method reduces the risk of carton collapse to a certain extent, because the structural properties of corrugated cardboard determine that the pressure resistance of the box is limited; add wooden frame packaging and wooden box packaging outside the carton for reinforcement. These two reinforcement methods both have the problem of large material usage, and there are also problems such as cumbersome nail and screw locking work and large unpacking workload.

[0003] In view of the shortcomings of the above background technology, relevant industry professionals have taken measures to improve and strengthen it. Add a supporting wooden bar inside the carton. To prevent the supporting wooden bar from shifting and falling inside the box, the wooden bar is locked with the box body of the carton by screws. With the support of the box body, the risk of the wooden bar shifting and falling inside the box is reduced. The connection between the bars is also reinforced by screws. This method enhances the pressure resistance of the packaging carton. However, the shortcomings are: after the bars are connected to the box body of the carton by screws, it will cause inconvenience to the folding, storage and transportation of the carton before use; at the same time, the screw locking of the bars and the box body, and the bars and the bars is labor-intensive, which will reduce work efficiency. Summary of the invention

[0004] In order to overcome the shortcomings of existing packaging cartons, the utility model provides a compression-resistant and shock-absorbing packaging carton. This packaging carton has compression resistance; the compression-resistant support and shock-absorbing buffering in the packaging operation are combined into the same operation process, which improves the efficiency of on-site packaging; the support member and the carton body do not need to be connected and locked, which does not affect the folding and storage of the carton before use.

[0005] The technical solution adopted by the utility model to solve its technical problems is: the utility model is a pressure-resistant shock-absorbing packaging carton composed of a box body, a shock-absorbing block, and a support member, and the support member and the shock-absorbing block are connected to form a plate. The snap-fit ​​positioning between any two components, such as the support member and the support member, the shock-absorbing block and the shock-absorbing block, and the support member and the shock-absorbing block, will realize the full positioning and fixation of the corresponding shock-absorbing block and the support member; with the help of the enclosure of the inner wall of the box, the movement and tipping of the shock-absorbing block and the support member are prevented, thereby achieving the stability of the entire support system. Specifically: the mutual snap-fit ​​positioning between the supports realizes the full positioning and fixation of the supports and the shock-absorbing blocks connected to the supports; the mutual snap-fit ​​positioning between the shock-absorbing blocks realizes the full positioning and fixation of the shock-absorbing blocks and the supports connected to the shock-absorbing blocks; the snap-fit ​​positioning between the supports and the shock-absorbing blocks realizes the full positioning and fixation of the supports, the shock-absorbing blocks connected to the supports, the shock-absorbing blocks, and the supports connected to the shock-absorbing blocks. The snap-fit ​​positioning structure of the shock-absorbing block has the advantages of convenient and quick processing.

[0006] To further explain, when some of the six sides and some of the edges of the packaging box do not need support and reinforcement, the support parts at that location do not need to be installed, and only shock-absorbing blocks can be installed; when some of the six sides and some of the edges of the packaging box do not need shock-absorbing and buffering, the shock-absorbing blocks at that location do not need to be installed, and only support parts can be installed; when some of the six sides and some of the edges of the packaging box do not need shock-absorbing and buffering and support and reinforcement, both the shock-absorbing blocks and support parts at that location can be omitted.

[0007] It is further explained that the shock-absorbing blocks on each surface of the packaging box are one of the following types: whole block type, segmented assembly type, segmented interval type, and hollow type.

[0008] Further explanation: the engagement and positioning method between the shock absorbing block and the shock absorbing block, and the shock absorbing block and the supporting member is: one end of one connecting object is inserted into the hole, notch, or groove of the other connecting object; the protrusion on one connecting object is inserted into the hole, notch, or groove of the other connecting object. The types of holes are divided into through holes and non-through holes. There are two ways to form holes: directly making holes on the connecting object to form holes; only notches are made on the connecting object, and the notches are surrounded by other packaging box components to form holes. Notches are divided into full-cut notches and non-full-cut notches. There are three ways to form notches: directly making notches on the connecting object; when the shock absorbing block is segmented, the length of some segments is shortened, and the length of adjacent segments is not shortened, and the difference in their lengths is used to form a notch; two connecting objects are spaced apart from each other, and the spacing area forms a notch together with other packaging box components.

[0009] It is further explained that when there is a risk of displacement and detachment at the joints where the supporting parts are engaged with each other due to processing deviation, load-bearing deformation, and gravity impact, the stability of the support system is further ensured by two methods. One is to install hardware on the supporting parts; the other is to process the joints between the two supporting parts into mortise and tenon structures to achieve a bite connection between the two supporting parts.

[0010] To further illustrate, the physical shape of the support member is one of a strip and a plate; and the material thereof is one of a metal material and a non-metal material.

[0011] Further explanation: the support and the shock-absorbing block are connected to form a plate, and there are four ways of connection: the first is that the support is directly engaged with the grooves, holes, and notches on the shock-absorbing block; the second is that the support is sunk into the grooves, holes, and notches on the shock-absorbing block and bonded together by adhesive materials; the third is that the support is sunk into the grooves, holes, and notches on the shock-absorbing block, and the inward enclosure force of the box body is used to prevent the support from falling off from the grooves, holes, and notches; the fourth is that the support is directly bonded to the outside of the shock-absorbing block. The connection is divided into pre-connection before the packaging materials leave the factory and on-site connection after the loose parts leave the factory; adding glue to reinforce the connection will further improve the stability of the connection.

[0012] The utility model provides a pressure-resistant and shock-absorbing packaging carton with the following beneficial effects: the packaging carton has high pressure resistance; the pressure-resistant support and shock-absorbing buffering of the packaging operation are combined into the same operation process, thereby improving the work efficiency of on-site packaging; the support member and the carton body do not need to be connected and locked, which does not affect the folding and storage of the carton before use.

DETAILED DESCRIPTION

[0052] In order to make the technical scheme of the utility model more clear and specific to those skilled in the art, the following preferred embodiments are provided, but the technical concept of the utility model is not limited to the following embodiments.

[0053] Embodiment 1

[0054] Figure 1, Figure 2 , Figure 3 , Figure 4 The thickness of the two long side regions of the bottom shock absorbing block (2) is smaller than the thickness of the main body thereof to form two groove-like structures, into which the bottom support block (1) is sunk and bonded together by glue. The long side edges of the bottom shock absorbing block (2) each have two notches, and the notches are used for the long side vertical support block (3) to pass through the bottom shock absorbing block (2) and directly connect with the bottom support block (1) during subsequent operations. The bottom support block (1) at the notch of the bottom shock absorbing block (2) is installed with an iron sheet (9) by means of screws (10), and the function of the iron sheet (9) is to engage the long side vertical support block (3) to prevent the long side vertical support block (3) from sliding and causing the long side vertical support block (3) to fall off and separate from the bottom support block (1).

[0055] Figure 5 , Figure 6 , Figure 7 , Figure 8 The long side shock absorbing block (4) has two groove-shaped structures in the short side direction, and the long side vertical support block (3) is stuck therein; the length of the long side vertical support block (3) is greater than the width of the long side shock absorbing block (4), and its two ends extend outward from the long side shock absorbing block (4).

[0056] Fig. 9 , Fig.10 In the embodiment, each end of the short side shock absorbing block (7) has a recessed notch, the width of which is equal to the thickness of the long side shock absorbing block (4). The function of the notch is to realize the mutual engagement and positioning of the long side shock absorbing block (4) and the short side shock absorbing block (7) to prevent the two from tipping over to the inside of the carton (8).

[0057] Fig.11 , Fig.12 , Fig.13 In the embodiment, the top shock absorbing block (6) has two groove-shaped structures in the short side direction, and each end of the groove-shaped structure has a notch, and the notch is used for the long side vertical support block (3) to pass through the top shock absorbing block (6) and directly connect with the top support block (5) during subsequent operation. The top support block (5) is stuck in the groove, and an iron sheet (9) is installed at its end by a screw (10). The function of the iron sheet (9) is to engage the long side vertical support block (3) to prevent the long side vertical support block (3) from sliding and causing the long side vertical support block (3) to fall off and separate from the top support block (5).

Since the long side vertical support block (3) is clamped with the long side damping block (4), the anti-dumping positioning of the long side vertical support block (3) is achieved. The long side vertical support block (3) extending outward from the bottom of the long side shock absorbing block (4) is inserted into the notch of the bottom shock absorbing block (2) and connected to the bottom support block (1); the iron sheet (9) installed on the bottom support block (1) clamps the long side vertical support block (3) extending outward from the bottom of the long side shock absorbing block (4) to prevent it from sliding outward and falling off.

[0060] Fig.16 After the packaging is loaded, the top shock absorbing block (6) with the top support block (5) is covered on the upper end of the box, the top support block (5) faces upward, the long side vertical support block (3) extending outward from the top of the long side shock absorbing block (4) is inserted into the gap of the top shock absorbing block (6) and connected with the top support block (5), and the iron sheet (9) installed on the top support block (5) clamps the long side vertical support block (3) extending outward from the top of the long side shock absorbing block (4) to prevent it from sliding outward and causing separation. After the cover of the carton (8) is sealed, the packaging is completed. At this time, under the enclosure of the six panels of the carton (8), the shock absorbing blocks in the box are fully positioned, and because the support blocks are connected and engaged with the shock absorbing blocks, the support blocks are also fully positioned. When the lid of the carton (8) is under pressure, the top support block (5) will share the pressure. The top support block (5) transfers the pressure to the bottom support block (1) through the long side vertical support block (3), thereby sharing the pressure of the carton (8) wall, thereby improving the overall pressure resistance of the packaging box.
