Description

Technical Field

[0001] This utility model relates to the field of packaging paper box technology, specifically a packaging paper box with an internal fixing structure. Background Technology

[0002] Paper box packaging is widely used in the transportation and sales packaging of various commodities such as electronic products, wine, cosmetics, and food due to its advantages such as low cost, convenient processing, easy printing, and environmental friendliness and recyclability; Authorized announcement number CN211309243U provides an environmentally friendly packaging cardboard box, including a corrugated paper core layer, a corrugated paper cover, a layer of polystyrene granules, a glass wool fireproof layer, a PVC reinforcing board, a thermoplastic polyurethane elastomer rubber waterproof layer, and a photocatalyst layer. The outer surface of the corrugated paper core layer is connected to the glass wool fireproof layer with environmentally friendly acrylic adhesive. This utility model incorporates a glass wool fireproof layer to improve the fire resistance of the packaging cardboard box, a thermoplastic polyurethane elastomer rubber waterproof layer to improve its waterproof performance, a layer of polystyrene granules to improve its thermal insulation performance, and a photocatalyst layer to sterilize and disinfect the surrounding environment, thus improving the environmental performance of the packaging cardboard box. Through the combination of these structures, the environmental friendliness of this packaging cardboard box is effectively improved, solving the problem of poor environmental performance of existing packaging cardboard boxes, which increases environmental pollution.

[0003] However, existing packaging boxes simply wrap fragile, shock-sensitive, and high-value items by filling them with fluffy materials such as lint. This protective structure still cannot guarantee that multiple items stored inside the box will not collide with each other and break. Moreover, the large amount of filling material greatly increases the cost of use. At the same time, the manual filling method cannot ensure its uniformity and the packaging efficiency is low. Therefore, in order to address the above problems, there is an urgent need to innovate the design of existing packaging boxes. Utility Model Content

[0004] The purpose of this utility model is to provide a packaging box with a built-in fixing structure to solve the current problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a packaging cardboard box with a built-in fixed structure, comprising: an outer wall of the cardboard box, and a top plate disposed on the upper side of the outer wall of the cardboard box, wherein a bottom plate is disposed at the lower end of the outer wall of the cardboard box; Also includes: The first reinforcing block is installed on the inner side of the outer wall of the cardboard box, and a connecting block is provided at one end of the first reinforcing block. A reinforcing tube is connected to the lower end of the first reinforcing block, and a second reinforcing block is provided at the lower end of the reinforcing tube. A storage cavity is installed on the inner side of the first reinforcing block, and a positioning block is provided on the outer side of the storage cavity. A positioning plate is installed inside the positioning block, and a first partition is connected to the inside of the positioning plate. A second partition is installed in the middle of the first partition. A buffer sleeve is provided inside the reinforcing tube, and adhesive is applied to the inside of the buffer sleeve.

[0006] In one possible implementation, the first reinforcing block has an isosceles trapezoidal cross-section and is positioned at equal angles on the inner side of the outer wall of the cardboard box.

[0007] In one possible scenario, the reinforcing tubes are arranged symmetrically about the central axis of the first reinforcing block.

[0008] In one possible scenario, the positioning block is engaged with the first reinforcing block, and the cross-section of the positioning block is a "T" shaped structure.

[0009] In one possible scenario, the positioning blocks are arranged symmetrically about the central axis of the receiving cavity.

[0010] In one possible implementation, the positioning plate is engaged with the first partition frame, and the positioning plate is symmetrically arranged about the central axis of the receiving cavity.

[0011] In one possible scenario, the second divider is engaged with the first divider.

[0012] In one possible scenario, the buffer sleeve is positioned at an equal angle inside the outer wall of the cardboard box.

[0013] Compared with the prior art, the present invention has at least the following beneficial effects: The packaging box with built-in fixed structure, by directly embedding a grid-shaped partition structure inside the device, allows the operator to directly put the items to be transported into the independent space created by the partition, thereby ensuring that multiple items stored inside the box will not collide with each other and be damaged. At the same time, the device adopts a spliced ​​rectangular reinforcement structure, which allows the special rectangular frame to effectively improve the device's pressure resistance when facing lateral pressure, preventing the carton from deforming and breaking immediately under pressure, thereby improving the stability of the device and having a better performance, as shown in the following details. 1. A rectangular reinforcing frame is formed inside the outer wall of the cardboard box by the first reinforcing block and the connecting block. The first reinforcing block, together with the reinforcing tube and the second reinforcing block, wraps and strengthens the inner cavity. This ensures that even if the device is hit by an external object during transportation, the reinforcing frame formed by the first reinforcing block, the reinforcing tube and the second reinforcing block can provide stronger support, preventing the device from collapsing and breaking immediately when squeezed, thereby improving the stability of the device. 2. By using adhesive to fix the cushioning sleeve to the outside of the storage cavity with the outer wall of the cardboard box, the cavity formed by the lack of contact between the storage cavity and the middle of the outer wall of the cardboard box is filled. This prevents the outer wall of the cardboard box from denting inward when subjected to lateral pressure, thus affecting the storage and protection effect of the storage cavity on the items. This further enhances the strength of the device. At the same time, during the connection between the storage cavity and the first reinforcing block, its bottom surface does not contact the low plate set on the lower side of the outer wall of the cardboard box to form a suspended support structure, thereby avoiding impact from the bottom. 3. By using the positioning plate in conjunction with the storage cavity, the second divider and the first divider are fixed inside the outer wall of the cardboard box. This allows the second divider and the first divider to form multiple grid-shaped cavities inside the storage cavity to secure the items. This facilitates the effective sorting and storage of multiple items when they need to be stored and transported, preventing multiple items from colliding and breaking inside the device. This greatly improves the load-bearing capacity of the device and makes the overall structure more robust. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] Please see Figures 1-5 The present invention provides the following technical solution: A packaging cardboard box with a built-in fixing structure includes: an outer wall of the cardboard box 1, a first reinforcing block 2, a connecting block 3, a reinforcing tube 4, a second reinforcing block 5, a top plate 6, a bottom plate 7, a storage cavity 8, a positioning block 9, a positioning plate 10, a first divider 11, a second divider 12, a cushioning sleeve 13, and adhesive 14. Specifically, such as Figure 1 , Figure 3 and Figure 5 As shown, before the device is used, by blocking the outer wall 1 of the cardboard box inward, the outer wall 1 of the cardboard box is made into a hollow rectangular cardboard box. At this time, due to the interlocking connection structure between the connecting block 3 and the first reinforcing block 2, the first reinforcing block 2 on each side is connected to the first reinforcing block 2 on other sides to form a rectangular reinforcing frame. At the same time, the second reinforcing block 5 connected to the lower end of the reinforcing tube 4 repeats the connection step of the first reinforcing block 2 to connect with other second reinforcing blocks 5, so that the first reinforcing block 2, together with the reinforcing tube 4 and the second reinforcing block 5, forms a three-dimensional reinforced inner frame. At this time, due to the interlocking connection between the positioning block 9 and the first reinforcing block 2... The structure allows operators to easily install the inner cavity 8 along the groove on the inner side of the first reinforcing block 2 inside the outer wall 1 of the cardboard box. At this time, the multiple first reinforcing blocks 2 are not easy to loosen under the series restraint of the inner cavity 8 and the positioning block 9. The first reinforcing blocks 2, together with the reinforcing tube 4 and the second reinforcing block 5, wrap and strengthen the inner cavity 8. This ensures that even if the device is hit by an external object during transportation, the reinforcing frame formed by the first reinforcing block 2, the reinforcing tube 4 and the second reinforcing block 5 can provide stronger support, preventing the device from collapsing and breaking immediately when squeezed, thereby improving the stability of the device. Meanwhile, before installing the storage cavity 8, the adhesive 14 is demolded onto the inside of the buffer sleeve 13, allowing the operator to attach the buffer sleeve 13 to the middle of the outer wall 1 of the cardboard box. This allows the buffer sleeve 13 inside the outer wall 1 of the cardboard box to form a lateral protective structure during the folding process. At the same time, the buffer sleeve 13 attached to the middle of the outer wall 1 of the cardboard box contacts the storage cavity 8 placed inside the outer wall 1 of the cardboard box, thus filling the cavity formed by the non-contact between the storage cavity 8 and the middle of the outer wall 1 of the cardboard box. This prevents the outer wall 1 of the cardboard box from denting inwards under lateral pressure, which would affect the storage protection effect of the storage cavity 8 on the items. This further strengthens the strength of the device. Also, during the connection between the storage cavity 8 and the first reinforcing block 2, its bottom surface does not contact the low plate 7 set on the lower side of the outer wall 1 of the cardboard box to form a suspended support structure, thereby avoiding impact from the bottom. Specifically, such as Figure 1 , Figure 2 and Figure 4 As shown, after the installation of the storage cavity 8 is completed, the top plate 6 and the bottom plate 7 at the upper and lower ends of the outer wall 1 of the cardboard box are folded inward. The top plate 6 and the bottom plate 7 then cover and fill the hollow outer wall 1 of the cardboard box. At this time, due to the engaging connection between the positioning plate 10 and the first divider 11, the operator can accurately embed the first divider 11 into the inside of the storage cavity 8. At the same time, due to the engaging connection between the second divider 12 and the first divider 11, the operator can combine the second divider 12 and the first divider 11 together to form multiple well-shaped cavities inside the storage cavity 8 to fix the items. This makes it easier for the device to effectively separate and store multiple items when they need to be stored and transported, avoiding damage caused by multiple items colliding with each other inside the device. This greatly improves the load-bearing capacity of the device and makes the overall structure more robust.
