Description

Technical Field

[0001] This invention belongs to the field of packaging technology, and in particular relates to a hook. Background Technology

[0002] Currently, hooks are an indispensable component in packaging structures. Existing hooks mainly include a wide-body mounting section for installation on the packaging structure, a narrow-body hanging section connected to a long side of the wide-body mounting section and extending outside the packaging structure. Typically, the narrow-body hanging section is provided with a hanging hole or a hook-like structure for easy hanging or holding.

[0003] To meet environmental protection requirements, existing hooks are usually made of paper-plastic material, which is relatively thin and has insufficient load-bearing capacity. They are prone to breakage when hung in stores for a long time, which seriously affects their use. Summary of the Invention

[0004] The purpose of this invention is to provide a hook that solves the problem of existing hooks being prone to breakage.

[0005] The present invention discloses a hook, the hook including a narrow body suspension part and a wide body mounting part connected to the narrow body suspension part; the narrow body suspension part includes two panels and a support layer sandwiched between the two panels, the support layer being fixedly connected to the two panels respectively; the wide body mounting part includes mounting plates respectively connected to the two panels, with a gap between the two mounting plates.

[0006] As an improvement, the support layer includes at least two bonding plates, and multiple sets of side-by-side insertion structures are provided between two adjacent bonding plates, with the outer bonding plates being fixedly connected to the corresponding panels.

[0007] As an improvement, the plug-in structure is a tenon joint structure.

[0008] As an improvement, the bonding board has two layers: a first corrugated board and a second corrugated board. The crest of the first corrugated board is configured as a first dovetail joint, and the trough of the first corrugated board is configured as a first dovetail groove. The end face of the first dovetail joint is positioned away from the corresponding side of the panel, and the bottom of the first dovetail groove is positioned close to the corresponding side of the panel. The trough of the second corrugated board is configured as a second dovetail groove that matches the first dovetail joint, and the crest of the second corrugated board is configured as a second dovetail joint that matches the first dovetail groove. The bottom of the second dovetail groove is positioned close to the corresponding side of the panel, and the end face of the second dovetail joint is positioned away from the corresponding side of the panel. The tenon joint structure is formed between the first dovetail joint and the second dovetail groove, and between the first dovetail groove and the second dovetail joint.

[0009] As an improvement, the end faces of the first dovetail joint of the first corrugated board are arranged on the same plane to form a first mating surface, and the bottom of the groove of the first dovetail joint of the first corrugated board is arranged on the same plane to form a first mounting surface; the end faces of the second dovetail joint of the second corrugated board are arranged on the same plane to form a second mating surface, and the bottom of the groove of the second dovetail joint of the second corrugated board is arranged on the same plane to form a second mounting surface; the first mounting surface and the second mounting surface are respectively mated to the panel on the corresponding side, and the first mating surface and the second mating surface are mated to each other.

[0010] As an improvement, a bend is provided at the connection between the panel and the mounting plate, and the two mounting plates can be folded outward along the bend.

[0011] As an improvement, the narrow-body suspension part is provided with hanging holes that penetrate through the two layers of the panel and the support layer.

[0012] As an improvement, the mounting plate is provided with multiple sets of side-by-side reinforcing ribs.

[0013] As an improvement, the reinforcing ribs are provided along the length extension direction of the mounting plate.

[0014] As an improvement, the reinforcing rib protrudes from the mounting plate, and a groove is provided on the other side of the mounting plate corresponding to the reinforcing rib, which is arranged in the same direction as the reinforcing rib.

[0015] By adopting the above technical solution, the hook of the present invention includes a narrow-body suspension part and a wide-body mounting part connected to the narrow-body suspension part. The narrow-body suspension part includes two panels and a support layer sandwiched between the two panels, with the support layer fixedly connected to both panels respectively. The wide-body mounting part includes mounting plates respectively connected to the two panels, with a gap between the two mounting plates. In use, because the narrow-body suspension part has two panels and a support layer sandwiched between them, the strength of the narrow-body suspension part is enhanced, thereby improving its tensile strength. Furthermore, the wide-body mounting part, including two spaced-apart mounting plates, enhances the connection strength between the narrow-body suspension part and the wide-body mounting part, and between the wide-body mounting part and the packaging structure. This avoids the problem of breakage of the narrow-body suspension part and the connection between the narrow-body suspension part and the wide-body mounting part during long-term suspension, thus solving the problem of easy breakage of existing hooks.

[0024] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the hook of this embodiment of the invention is applied to a packaging structure (e.g., a packaging box, a carton, etc.), including a narrow suspension part 10 and a wide mounting part 20 connected to the narrow suspension part 10. The hook is installed on the packaging structure through the wide mounting part 20. The narrow suspension part 10 includes two panels 11 and a support layer 30 sandwiched between the two panels 11. The support layer 30 is fixedly connected to the two panels 11 respectively. The wide mounting part 20 includes mounting plates 21 connected to the two panels 11 respectively, and a gap is provided between the two mounting plates 21.

[0025] In use, the narrow-body suspension part 10 has two panels 11 and a support layer 30 sandwiched between the two panels 11, which can enhance the strength of the narrow-body suspension part 10 and improve its tensile performance. The wide-body mounting part 20 includes two spaced mounting plates 21, which can also enhance the connection strength between the narrow-body suspension part 10 and the wide-body mounting part 20, and between the wide-body mounting part 20 and the packaging structure, thus avoiding the problem of the narrow-body suspension part 10 breaking during long-term suspension and the breakage between the narrow-body suspension part 10 and the wide-body mounting part 20. The hook of the present invention solves the problem of the easy breakage of existing hooks.

[0026] In this embodiment of the invention, the support layer 30 includes at least two bonding plates, and multiple sets of side-by-side insertion structures are provided between two adjacent bonding plates. The two bonding plates on the outer side are respectively fixedly connected to the panel 11 on the corresponding side.

[0027] Specifically, the plug-in structure is designed as a tenon joint structure.

[0028] like Figure 3 and Figure 4As shown, the bonding board has two layers: a first corrugated board 31 and a second corrugated board 32. The crest of the first corrugated board 31 is configured as a first dovetail joint 311, and the trough of the first corrugated board 31 is configured as a first dovetail groove 312. The end face of the first dovetail joint 311 is positioned away from the corresponding side panel 11, and the bottom of the first dovetail groove 312 is positioned close to the corresponding side panel 11. The trough of the second corrugated board 32 is configured as a first dovetail joint 311 that is compatible with the first dovetail joint 311. The dovetail joint 321 and the crest of the second corrugated plate 32 are configured as a second dovetail joint 322 that is adapted to the first dovetail joint 312. The bottom of the second dovetail joint 321 is set close to the panel 11 on the corresponding side, and the end face of the second dovetail joint 322 is set away from the panel 11 on the corresponding side. The above-mentioned tenon joint structure is formed between the first dovetail joint 311 and the second dovetail joint 321, and between the first dovetail joint 312 and the second dovetail joint 322.

[0029] For ease of installation, the end face of the first dovetail joint 311 of the first corrugated plate 31 is set on the same plane to form a first mating surface, and the bottom of the groove of the first dovetail groove 312 of the first corrugated plate 31 is set on the same plane to form a first mounting surface, so as to facilitate fixed connection with the panel 11 on the corresponding side; the end face of the second dovetail joint 322 of the second corrugated plate 32 is set on the same plane to form a second mating surface, and the bottom of the groove of the second dovetail groove 321 of the second corrugated plate 32 is set on the same plane to form a second mounting surface, so as to facilitate fixed connection with the panel 11 on the corresponding side; after installation, the first mounting surface of the first corrugated plate 31 and the second mounting surface of the second corrugated plate 32 are respectively mated with the panel 11 on the corresponding side, and the first mating surface of the first corrugated plate 31 and the second mating surface of the second corrugated plate 32 are mated with each other.

[0030] In some other embodiments, the support layer 30 may also be configured as a single-layer structure.

[0031] In this embodiment of the invention, in order to further improve the strength and prevent the hook from breaking, multiple sets of parallel reinforcing ribs 22 are provided on the mounting plate 21.

[0032] Specifically, the reinforcing rib 22 is provided along the length of the mounting plate 21, that is, it extends horizontally. Typically, the reinforcing rib 22 protrudes from the mounting plate 21, and a groove 23 is provided on the other side of the mounting plate 21 at the location corresponding to the reinforcing rib 22, which is in the same direction as the reinforcing rib 22.

[0033] In this embodiment of the invention, a bending portion (not shown in the figure) is provided at the connection between the panel 11 and the mounting plate 21. The two mounting plates 21 can be folded outward along the bending portion to facilitate the fixed connection of the mounting plate 21 to the packaging structure (e.g., a packaging box). Typically, this is achieved by adhesive bonding. Specifically, the bending portion is an indentation provided at the connection between the panel 11 and the mounting plate 21.

[0034] In use, the mounting plates 21 can be left folded outwards; in this case, the portions of the two mounting plates 21 extending to the outer side of the panel 11 form a limit. Specifically, the installation method between the hook and the packaging structure is known technology and will not be described further here.

[0035] In this embodiment of the invention, in order to facilitate hanging, the narrow-body hanging part 10 is provided with a hanging hole 12, which penetrates the two panels 11 and the support layer 30.

[0036] In some other embodiments, the narrow-body suspension portion 10 may also be configured as a hook-shaped structure.

[0037] The above description is merely some embodiments of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
