Description

Technical Field

[0001] This utility model relates to the field of packaging carton technology, and in particular to a structure for improving the compression resistance of cartons. Background Technology

[0002] Cardboard boxes, as a common packaging material, are lightweight, recyclable, and inexpensive, effectively matching the modern green and environmentally friendly lifestyle concept. They have become an indispensable packaging solution and are widely used in logistics and commodity packaging.

[0003] Current cardboard boxes have significant deficiencies in compression resistance, especially during stacking and transportation, they are prone to deformation and collapse, which can easily lead to box damage. The contents of the box may be exposed, potentially causing damage to the packaged product. Furthermore, when deformed cardboard boxes are stacked, the support points are uneven, which may cause the boxes to shake or even tip over, making it difficult to ensure the safe and stable transportation of goods.

[0004] Therefore, in view of the insufficient compression resistance of existing cardboard boxes, which affects the safe and stable transportation of goods, a structure to improve the compression resistance of cardboard boxes can be designed. By using multi-directional pressure distribution, the pressure-bearing capacity of the corners and center of the box can be improved, avoiding damage to the corners and ensuring the overall support and stacking stability of the box, thereby effectively enhancing the compression resistance of the cardboard box. Utility Model Content

[0005] To overcome the significant deficiencies in the compression resistance of most cardboard boxes, especially their tendency to deform and collapse during stacking and transportation, which may damage the packaged products, and the uneven support points when deformed cardboard boxes are stacked, making it difficult to ensure the safe and stable transportation of goods, this utility model is proposed.

[0006] The technical solution of this utility model is as follows: a structure for improving the compression resistance of a cardboard box, including a cardboard box body, a lower honeycomb plate, an upper honeycomb plate, a V-shaped reinforcing plate, a reinforcing rod, a support plate, and a strip reinforcing plate. The lower honeycomb plate is provided on the four sides of the bottom of the cardboard box body, the upper honeycomb plate is provided on the four sides of the top of the cardboard box body, the V-shaped reinforcing plate is symmetrically provided at the four corners of the inner side of the cardboard box body, the reinforcing rod is provided in the middle of the inner side of the cardboard box body, two sets of support plates are symmetrically provided at both ends of the reinforcing rod, and two sets of strip reinforcing plates are symmetrically provided at the top of the V-shaped reinforcing plate.

[0007] Preferably, the bottom of the carton is sealed by folding up the lower honeycomb panel, the right-angled edges of the carton body are reinforced by V-shaped reinforcing plates, the reinforcing rods are supported and fixed by support plates, and the reinforcing rods enhance the support of the suspended part in the middle of the carton body. The support plates are stably fixed in the carton body by placing two sets of strip reinforcing plates crosswise, further enhancing the pressure resistance of the top of the carton body. The top of the carton body is sealed by folding up the upper honeycomb panel, thereby improving the pressure resistance of the corners and middle of the carton body, preventing damage to the corners of the carton body, ensuring the overall support and stacking stability of the carton body, and enhancing the compression resistance of the carton.

[0008] Preferably, four sets of lower and upper honeycomb panels are symmetrically arranged, the strip reinforcing plates are arranged in an X-shape, and the internal structure of the V-shaped reinforcing plates, support plates, and strip reinforcing plates is set as a honeycomb structure.

[0009] Preferably, one of the symmetrically positioned lower honeycomb panels has a protrusion at its bottom end, the outer surface of the protrusion being arc-shaped, and the protrusion being made of a non-slip silicone material.

[0010] Preferably, the top of another set of symmetrically positioned lower honeycomb panels is provided with a first circular groove, and the support plate is fitted and connected to the first circular groove.

[0011] Preferably, the top of the V-shaped reinforcing plate is provided with a slot, and the bottom surfaces of both ends of the strip-shaped reinforcing plate are provided with V-shaped clamping plates, which are fitted and connected to the slot.

[0014] The beneficial effects of this utility model are:

[0015] When using cardboard boxes, fold up the lower honeycomb panel to seal the bottom of the box. Then, place the support plate on the lower honeycomb panel and place the items into the box in sequence. Use V-shaped reinforcing plates to reinforce the right-angled edges of the box body. Use reinforcing rods to enhance the support of the suspended part in the middle of the box. Place two sets of strip reinforcing plates crosswise on the V-shaped reinforcing plate to stably fix the support plate in the box body, further enhancing the pressure resistance of the top of the box. Finally, fold up the upper honeycomb panel to seal the top of the box. This method addresses the significant deficiencies in the compression resistance of most cardboard boxes, especially their tendency to deform and collapse during stacking and transportation, which can damage the packaged products.

Detailed Implementation

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Please see Figure 1 and Figure 3 This utility model provides an embodiment: a structure for improving the compression resistance of a cardboard box, including a cardboard box body 1, a lower honeycomb plate 2, an upper honeycomb plate 3, a V-shaped reinforcing plate 4, reinforcing rods 5, a support plate 6, and strip-shaped reinforcing plates 7. The lower honeycomb plates 2 are arranged on the four sides of the bottom of the cardboard box body 1, and the upper honeycomb plates 3 are arranged on the four sides of the top of the cardboard box body 1. Four sets of lower honeycomb plates 2 and upper honeycomb plates 3 are symmetrically arranged. V-shaped reinforcing plates 4 are symmetrically arranged at the four inner corners of the cardboard box body 1. The right-angled edges of the carton body 1 are reinforced by V-shaped reinforcing plates 4. A reinforcing rod 5 is set in the middle of the inner side of the carton body 1 to enhance the support of the suspended part in the middle of the carton body 1. Two sets of support plates 6 are symmetrically set at both ends of the reinforcing rod 5. Two sets of strip reinforcing plates 7 are symmetrically set at the top of the V-shaped reinforcing plate 4. The strip reinforcing plates 7 are arranged in an X-shape. The internal structure of the V-shaped reinforcing plate 4, the support plates 6 and the strip reinforcing plates 7 are all set as honeycomb structures.

[0024] Please see Figure 2 and Figure 3In this embodiment, a protrusion 201 is provided at the bottom of one set of symmetrically positioned lower honeycomb plates 2. The outer surface of the protrusion 201 is arc-shaped and made of non-slip silicone material. The protrusion 201 enhances the non-slip properties of the lower honeycomb plate 2, increases the friction between the lower honeycomb plate 2 and the contact surface, and prevents the carton body 1 from easily sliding relative to each other, thus ensuring the stable stacking of the carton body 1. A first circular groove 202 is provided at the top of another set of symmetrically positioned lower honeycomb plates 2. The support plate 6 is fitted and connected to the first circular groove 202, and the installation position of the support plate 6 is defined by the first circular groove 202.

[0025] Please see Figure 4 and Figure 5 In this embodiment, the top of the V-shaped reinforcing plate 4 is provided with a slot 401, and the bottom surfaces of both ends of the strip-shaped reinforcing plate 7 are provided with V-shaped clamping plates 701. The V-shaped clamping plates 701 are fitted into the slot 401. The bottom end of one set of strip-shaped reinforcing plates 7 is provided with a second circular groove 702, which is fitted into the support plate 6. When two sets of strip-shaped reinforcing plates 7 are placed crosswise, the V-shaped clamping plates 701 are embedded into the slot 401, thereby fixing the position of the strip-shaped reinforcing plates 7 and making the two sets of strip-shaped reinforcing plates 7 stably placed crosswise. Placed on the V-shaped reinforcing plate 4, another set of support plates 6 are fitted into the second circular groove 702 to stably fix the support plates 6 inside the carton body 1; the top of the strip reinforcing plate 7 with the second circular groove 702 is provided with a positioning groove 703, and the bottom of the other set of strip reinforcing plates 7 is provided with a positioning groove 703. The strip reinforcing plates 7 are placed crosswise through the positioning grooves 703, and the positioning grooves 703 ensure that the strip reinforcing plates 7 are stably placed crosswise, ensuring that the two sets of crosswise reinforcing plates 7 remain on the same horizontal plane.

[0026] When using a cardboard box, fold up the lower honeycomb plate 2 and use tape to seal the lower honeycomb plate 2 tightly so that the lower honeycomb plate 2 seals the bottom of the cardboard box body 1. Then place the support plate 6 into the first circular groove 202 on the lower honeycomb plate 2, and then put the items into the cardboard box body 1 in sequence.

[0027] Subsequently, the strip-shaped reinforcing plate 7 with the second circular groove 702 is placed on the diagonally opposite V-shaped reinforcing plate 4, so that the V-shaped clamping plate 701 is embedded in the clamping groove 401. At this time, the support plate 6 located at the top is embedded in the second circular groove 702. Then, another set of strip-shaped reinforcing plates 7 are placed crosswise on the installed strip-shaped reinforcing plate 7, so that the V-shaped clamping plate 701 is embedded in the clamping groove 401. The positioning groove 703 is used to make the two sets of strip-shaped reinforcing plates 7 crosswise placed on the V-shaped reinforcing plate 4.

[0028] Finally, the top of the carton body 1 is closed by folding up the upper honeycomb plate 3. The right-angled edges of the carton body 1 are reinforced by the V-shaped reinforcing plate 4. The support of the suspended part in the middle of the carton body 1 is enhanced by the reinforcing rod 5 and the support plate 6, which further enhances the pressure resistance of the top of the carton body 1. The anti-slip properties of the lower honeycomb plate 2 are enhanced by the protrusion 201, which increases the friction between the lower honeycomb plate 2 and the contact surface, and prevents the carton body 1 from easily sliding relative to each other.

[0029] Through the above steps, the bottom of the carton body 1 is closed by folding up the lower honeycomb plate 2, the right-angled edges of the carton body 1 are reinforced by the V-shaped reinforcing plate 4, the reinforcing rod 5 is supported and fixed by the support plate 6, and the reinforcing rod 5 is used to enhance the support of the suspended part in the middle of the carton body 1. The support plate 6 is stably fixed inside the carton body 1 by placing two sets of strip reinforcing plates 7 crosswise, further enhancing the pressure resistance of the top of the carton body 1. The top of the carton body 1 is closed by folding up the upper honeycomb plate 3, thereby improving the pressure resistance of the corners and middle of the carton body, avoiding damage to the corners of the carton body, and ensuring the overall support and stacking stability of the carton body.

[0030] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
