Description

Technical Field

[0001] The utility model relates to the technical field of cartons, and more specifically to a carton capable of reducing external extrusion deformation. Background Art

[0002] In the traditional logistics transportation and commodity distribution process, cartons, as one of the most commonly used packaging materials, have multiple functions such as protecting the internal goods and facilitating handling and storage.

[0003] However, common corrugated boxes often face deformation problems caused by external extrusion and impact due to limitations in structural design and material strength. This deformation not only affects the appearance of the goods, but may also cause damage to the internal items, increase the product loss rate and the company's after-sales costs.

[0004] After searching, a Chinese patent with authorization announcement number CN217375292U discloses a paper box with an anti-extrusion deformation structure. The structure is achieved by inserting a bevel plate into a groove. After the bevel plate is inserted into the groove, the card plate is pushed to open, so that the bevel plate and the fixed paper are fixed, so that a triangle is formed between the two inner papers and the inclined paper, making the paper box more stable and supporting the inner paper on all sides. This structure increases the strength of the paper box through the stability of the triangle, thereby preventing the paper box from being deformed due to extrusion.

[0005] However, in actual use, this structure only improves the anti-deformation effect of the bottom of the inner cavity of the carton, and the anti-extrusion deformation effect of the carton as a whole and the outside is not ideal. The carton will be subject to collision and extrusion from all sides during logistics transportation or commodity distribution. In view of this, the utility model proposes a carton that reduces external extrusion deformation. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the utility model provides a carton that reduces external extrusion deformation, so as to solve the problems raised in the above-mentioned background technology.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a carton that reduces external extrusion deformation, including a carton body, the carton body is spliced ​​by a plurality of side panels, a plurality of support blocks are evenly distributed on the bottom of the inner cavity of the carton body, the two ends of the support blocks are respectively connected to the bottom side panel and the outer side panel of the carton body, and the support blocks are trapezoidal structures.

[0008] It can be seen that in the above structure, the support block with a trapezoidal structure connects the side panels at the bottom of the inner cavity of the carton body and the outer side panels, which can improve the support effect and strength of the bottom of the carton body.

[0009] In order to provide a wrapping protection effect to the outside of the carton and prevent the outside of the carton body from being deformed by being squeezed from all sides, preferably, a plurality of groups of anti-extrusion relief structures are provided on the outside of the carton body, and each group of the anti-extrusion relief structures includes four reinforcing plates, and the four reinforcing plates are installed on the outer walls of the side plates belonging to the carton body, wherein an L-shaped block is provided between every two reinforcing plates, and movable cavities are opened at both ends of the reinforcing plates, and movable rods are provided at both ends of the L-shaped blocks, and an extrusion plate is provided at one end of the movable rod, and a plurality of elastic sheets are provided at one end of the extrusion plate, and the movable rod and the extrusion plate are slidably connected inside the movable cavity opened by the reinforcing plate, and the two ends of the elastic sheet are respectively connected to the inner wall of the movable cavity and the extrusion plate.

[0010] In order to improve the overall pressure resistance of the carton body, preferably, the side panel includes a first pressure-resistant plate and a second pressure-resistant plate, the second pressure-resistant plate is at the bottom of the first pressure-resistant plate, and a plurality of pressure-resistant strips are evenly distributed at the bottom of the first pressure-resistant plate and the top of the second pressure-resistant plate, and support plates are provided at both ends of the pressure-resistant strips, and the pressure-resistant strips are respectively connected to the first pressure-resistant plate and the second pressure-resistant plate through the support plates, the pressure-resistant strips are arc-shaped structures, the pressure strips at the bottom of the first pressure-resistant plate and the pressure strips on the surface of the second pressure-resistant plate are symmetrically arranged and fit each other, the support plates are obliquely installed at the two ends of the pressure strips, and a triangular structure is formed between the support plates and the pressure strips.

[0011] Technical effects and advantages of the utility model:

[0012] 1. By setting up the anti-extrusion relief structure, multiple groups of anti-extrusion relief structures are installed on the outside of the carton body to provide wrapping protection for the periphery of the carton body. Once the outside of the carton body is squeezed from all sides, the movable rod and the extrusion plate corresponding to one end of the L-shaped block will slide inside the movable cavity opened by the reinforcing plate. During the sliding process, the extrusion plate will squeeze the elastic sheet, thereby reducing the extrusion force, providing good protection for the entire carton body and preventing the outside of the carton body from being squeezed and deformed;

[0013] 2. The carton body is composed of a plurality of side panels, each of which is composed of a first anti-compression plate, a second anti-compression plate, a pressure strip and a support plate. First, the first anti-compression plate and the second anti-compression plate can improve the strength of the side panel to which the carton body belongs. At the same time, a plurality of arc-shaped pressure strips that are fitted to each other and symmetrically arranged can distribute the extrusion force and improve the overall pressure resistance of the side panel. Moreover, the triangular structure formed between the pressure strip and the corresponding two support plates further improves the pressure resistance level of the side panel.

[0014] 3. By pasting a plurality of support blocks with a trapezoidal structure on the side panels at the bottom and the outer side panels of the carton body, the two ends of the support blocks are respectively connected to the bottom side panels and the outer side panels, ensuring that the bottom of the carton body has good pressure resistance, thereby avoiding deformation of the bottom of the carton.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] As attached Figure 1-5 The carton shown in the figure for reducing external extrusion deformation includes a carton body 1, which is composed of a plurality of side panels 2 spliced ​​together. A plurality of support blocks 3 are evenly distributed at the bottom of the inner cavity of the carton body 1, and the two ends of the support blocks 3 are respectively connected to the bottom side panel 2 and the outer side panel 2 belonging to the carton body 1, and the support blocks 3 are trapezoidal structures.

[0023] Specifically, in this structure, a plurality of support blocks 3 with a trapezoidal structure are pasted on the side panels 2 at the bottom and the outer side panels 2 of the carton body 1, so that the two ends of the support blocks 3 are respectively connected to the bottom side panels 2 and the outer side panels 2, thereby ensuring that the bottom of the carton body 1 has good pressure resistance and thus avoiding deformation of the bottom of the carton.

[0024] In a specific embodiment, as shown in the attached Figure 1 , 2 As shown in Figure 3, a plurality of groups of anti-extrusion relief structures are arranged on the outside of the carton body 1, and each group of anti-extrusion relief structures includes four reinforcing plates 4, and the four reinforcing plates 4 are installed on the outer wall of the side plate 2 belonging to the carton body 1, wherein an L-shaped block 5 is arranged between every two reinforcing plates 4, and a movable cavity 6 is opened at both ends of the reinforcing plate 4, and a movable rod 7 is arranged at both ends of the L-shaped block 5, and an extrusion plate 8 is arranged at one end of the movable rod 7, and a plurality of elastic sheets 9 are arranged at one end of the extrusion plate 8, and the movable rod 7 and the extrusion plate 8 are slidably connected inside the movable cavity 6 opened by the reinforcing plate 4, and the two ends of the elastic sheet 9 are respectively connected to the inner wall of the movable cavity 6 and the extrusion plate 8.

[0025] Specifically, in this structure, multiple sets of anti-extrusion relief structures are installed on the outside of the carton body 1, which can protect the outside of the carton body 1 and prevent the outside of the carton body 1 from being squeezed and deformed. Specifically, when the outside of the carton body 1 is squeezed from all sides, the movable rod 7 and the extrusion plate 8 corresponding to one end of the L-shaped block 5 will slide inside the movable cavity 6 opened by the reinforcing plate 4. During the sliding process, the extrusion plate 8 will squeeze the elastic sheet 9, thereby reducing the extrusion force, which has a good protective effect on the entire carton body 1 and prevents the outside of the carton body 1 from being squeezed and deformed.

[0026] In a specific embodiment, as shown in the attached Figure 1 , 4 As shown, the side plate 2 includes a first anti-compression plate 20 and a second anti-compression plate 21. The second anti-compression plate 21 is at the bottom of the first anti-compression plate 20. A plurality of pressure strips 22 are evenly distributed at the bottom of the first anti-compression plate 20 and the top of the second anti-compression plate 21. Support plates 23 are provided at both ends of the pressure strips 22, and the pressure strips 22 are respectively connected to the first anti-compression plate 20 and the second anti-compression plate 21 through the support plates 23. The pressure strips 22 are arc-shaped structures. The pressure strips 22 at the bottom of the first anti-compression plate 20 and the pressure strips 22 on the surface of the second anti-compression plate 21 are symmetrically arranged and fit each other. The support plates 23 are obliquely installed at the two ends of the pressure strips 22, and a triangular structure is formed between the support plates 23 and the pressure strips 22.

Moreover, the triangular structure formed between the pressure strip 22 and the corresponding two support plates 23 further improves the pressure resistance level of the side panel 2.

[0028] Working principle of this utility model:

[0029] When the above structure is used in practice, firstly, the bottom of the inner cavity of the carton body 1 is provided with a plurality of support blocks 3 of a trapezoidal structure, which can improve the supporting and compressive resistance effect of the bottom of the carton body 1. Secondly, the carton body 1 is composed of a plurality of side panels 2. A compression plate and a second compression plate 21 at each side panel 2 can improve the strength of the side panel 2 to which the carton body 1 belongs. At the same time, a plurality of arc-shaped pressure strips 22 that fit each other and are symmetrically arranged can share the extrusion force and improve the overall compressive resistance effect of the side panel 2. Moreover, the triangular structure formed between the pressure strip 22 and the corresponding two support panels 23 further improves the compressive resistance level of the side panel 2.

[0030] A plurality of anti-extrusion relief structures are installed on the outside of the carton body 1 to provide wrapping protection for the periphery of the carton body 1. Once the outside of the carton body 1 is squeezed from all sides, the movable rod 7 and the extrusion plate 8 corresponding to one end of the L-shaped block 5 will slide inside the movable cavity 6 opened by the reinforcing plate 4. During the sliding process, the extrusion plate 8 will squeeze the elastic sheet 9, thereby reducing the squeezing force, thereby providing good protection for the carton body 1 as a whole and preventing the outside of the carton body 1 from being squeezed and deformed.

[0031] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
