Description
Technical Field
[0001] This utility model relates to the field of paper-plastic clothes hangers, specifically to a high-strength paper-plastic clothes hanger with detachable hooks. Background Technology
[0002] Paper-plastic hangers, as an environmentally friendly clothing hanging tool, use paper materials instead of traditional plastics and metals, offering advantages such as biodegradability and low cost, and are gradually gaining attention in the pursuit of green living. However, some paper-plastic hangers lack a detachable connection between the hook and the hanger body, limiting their use or increasing recycling costs. For example, in the environmentally friendly pulp hanger disclosed in patent publication number CN212368757U, the hook and hanger body are fixedly connected by a pulp molding process. While this provides strength and environmental friendliness, it lacks a detachable structure, making it impossible to disassemble and compress during transportation, and requiring complete disposal after damage, which is detrimental to resource recycling.
[0003] Therefore, paper-plastic hangers that combine convenient detachability with environmentally friendly materials have become a focus of industry research and development. For example, in an environmentally friendly hanger disclosed in patent publication number CN203539023U, the hook is connected to the groove of the hanging body made of gray and white cardboard through a fixing slot, achieving a detachable connection between the hook and the hanging body. However, the structure of this environmentally friendly hanger relies on the cooperation of a single-plane slot and groove, resulting in insufficient stability during connection and a tendency for lateral shifting or detachment. Furthermore, it relies on the thickness of the paper or multiple layers of adhesive to ensure strength, leading to a higher material consumption and cost. Utility Model Content
[0004] To address the problems of traditional paper-plastic hangers, such as inconvenient transportation and high recycling costs due to the lack of detachable connection between the hook and the hanger body, and the instability and high material consumption caused by the reliance on a single planar interlocking structure for detachable paper-plastic hangers, this utility model provides a high-strength paper-plastic hanger with detachable hooks.
[0005] The technical solution of this utility model is as follows:
[0006] A high-strength paper-plastic hanger with a detachable hook includes a hanger body and a hook, wherein the hanger body and the hook are detachably connected and both are made of paper material; the side wall of the mounting part of the hanger body is recessed inward, forming a pair of protrusions and grooves inside the hanger body; the bottom of the hook, as the mounting end, is provided with a groove and protrusion structure that matches the mounting part; the hook passes through the mounting hole of the hanger body from bottom to top, so that the mounting end of the hook and the mounting part of the hanger body are engaged with each other through the concave and convex structure.
[0007] As a preferred technical solution of this utility model, each side wall of the assembly part of the hanger body is provided with two recessed grooves, two first protrusions are formed inside the hanger body, and a first groove is formed between the two first protrusions; the assembly end of the hook is provided with two second grooves that are adapted to the first protrusions, and a second protrusion that is adapted to the first groove is formed between the two second grooves.
[0008] Furthermore, the bottom of the recessed groove is arc-shaped.
[0009] As a preferred technical solution of this utility model, the hook side is provided with a limiting tongue, the upper side of which is a gentle surface and the lower side of which is a steep surface.
[0010] Preferably, the upper side of the limiting tongue forms an angle of 10° to 30° with the horizontal plane, forming the gentle surface; the lower side of the limiting tongue forms an angle of 45° to 90° with the horizontal plane, forming the steep surface.
[0011] As a preferred embodiment of this utility model, the assembly hole is located at the center of the top surface of the hanger body and is in the form of a strip-shaped hole.
[0012] Furthermore, the gap width of the strip hole is greater than the thickness of the hook but less than the maximum thickness of the limiting tongue.
[0013] By adopting the above technical solution, when the hook passes through the assembly hole from bottom to top, the flat surface of the limiting latch undergoes elastic deformation under force, allowing the limiting latch to pass through the assembly hole; when the hook is assembled in place, the steep surface of the limiting latch recovers its deformation and abuts against the edge of the assembly hole, preventing the hook from falling off naturally.
[0014] As a preferred technical solution of this utility model, the top wall of the shoulder of the main body of the clothes hanger is provided with a first structural reinforcement groove, and the first structural reinforcement groove is arranged along the length direction of the shoulder.
[0015] As a preferred technical solution of this utility model, the side wall of the shoulder end of the main body of the clothes hanger is provided with a plurality of second structural reinforcement grooves, and the second structural reinforcement grooves are arranged perpendicular to the length direction of the shoulder.
[0016] As a preferred technical solution of this utility model, the hook includes a first hook body and a second hook body. The first hook body and the second hook body are two symmetrical structures cut and pressed from the same cardboard, and the top ends of the first hook body and the second hook body are connected and can be folded.
[0017] As a preferred technical solution of this utility model, the groove and protrusion structure of the assembly end of the hook includes two second grooves and a second protrusion located in the middle, and also includes side protrusions located on both sides of the two second grooves. The side protrusions are engaged with the side gap in the assembly part of the clothes hanger body.
[0018] As a preferred embodiment of this utility model, the main body of the hanger is provided with an inner lining, which is inserted into the interior of the main body of the hanger from bottom to top.
[0019] Furthermore, the top surface of the lining has four arc-shaped grooves at its four corners, and these four arc-shaped grooves are adapted to the four first protrusions inside the main body of the hanger.
[0020] The advantages of this utility model based on the above solution are as follows:
[0021] The main body and hook of this utility model are both made of paper material, forming an all-paper biodegradable structure; the side wall of the assembly part of the main body of the hanger is recessed to form an internal pair of concave and convex structures, and the bottom assembly end of the hook is provided with a matching concave and convex structure. The three-dimensional snap-fit achieves detachable connection, and can be disassembled and assembled by hand without tools, which significantly improves the ease of operation.
[0022] Furthermore, the concave and convex structure of the hanger body has a structural reinforcement effect, which improves the strength of the assembly parts while reducing the thickness or number of paper materials and reducing material costs. After the hook passes through the assembly hole from bottom to top, its concave and convex structure forms a multi-dimensional limit with the corresponding structure of the hanger body. Compared with the single plane engagement of the existing technology, it significantly enhances the connection firmness and avoids problems such as lateral displacement or falling off.

[0038] Example 1
[0039] like Figure 1 and Figure 2As shown, a high-strength paper-plastic hanger with detachable hooks includes a hanger body 1 and hooks 2. The hanger body 1 and hooks 2 are detachably connected, facilitating disassembly and volume compression during transportation, thus reducing warehousing and logistics costs. Both the hanger body 1 and hooks 2 are made of paper, with the paper components being pure wood pulp, bamboo pulp, or sugarcane pulp, or corrugated paper pulp. This solves the problem of non-biodegradability of traditional plastic or metal hangers, allowing for natural decomposition after disposal without environmental pollution.
[0040] The sidewall of the assembly part 11 of the hanger body 1 is recessed inward, forming a pair of protrusions and grooves inside the hanger body 1. The bottom of the hook 2, serving as the assembly end 21, has grooves and protrusions that match the assembly part 11. The grooves and protrusions of the hook 2 assembly end 21 complement and match the protrusions and grooves of the assembly part 11 of the hanger body 1. When the hook 2 passes through the assembly hole 113 from bottom to top, the concave and convex structures form a snap-fit through physical interlocking. The slight elasticity of the paper material achieves a tight fit, allowing for easy assembly and disassembly by hand without tools, thus improving usability. The three-dimensional fit of the concave and convex structures creates constraints in both the horizontal and vertical directions: in the horizontal direction, the sidewalls of the concave and convex structures abut against and limit offset; in the vertical direction, the snap-fit depth limits detachment. Combined with the guidance of the assembly hole 113 on the movement path of the hook 2, multi-dimensional stable positioning is achieved.
[0041] The side wall recess of the assembly part 11 of the main body of the clothes hanger creates a pair of concave and convex structures inside. This structure increases the three-dimensional support dimension of the material and distributes the external force to multiple contact surfaces of the concave and convex structures, reducing stress concentration in a single part and thus improving the overall strength without relying on increasing the material thickness or multiple layers of bonding.
[0042] like Figure 3 As shown, in this embodiment, each side wall of the assembly portion 11 of the hanger body 1 is provided with two recessed grooves 110, two first protrusions 111 are formed inside the hanger body 1, and a first groove 112 is formed between the two first protrusions 111; the assembly end 21 of the hook 2 is provided with two second grooves 212 that are adapted to the first protrusions 111, and a second protrusion 211 that is adapted to the first groove 112 is formed between the two second grooves. The assembly portion 11 of the hanger body 1 on one side is provided with two recessed grooves 110, forming a three-dimensional combination structure of double protrusions + single groove, which significantly enhances the connection firmness compared to a single concave-convex structure.
[0043] In a preferred embodiment, the bottom of the recessed groove 110 is arc-shaped. The arc-shaped bottom of the groove makes the bottom of the first protrusion 111 formed by the recessed groove 110 have an arc-shaped surface, which is beneficial to improving the structural strength of the first protrusion 111.
[0044] like Figure 1As shown, in this embodiment, the groove and protrusion structure of the mounting end 21 of the hook 2 includes two second grooves 212 and a second protrusion 211 located in the middle, and also includes side protrusions 213 located on both sides of the two second grooves 212. The side protrusions 213 engage with the side gap in the mounting part 11 of the hanger body 1. The engagement of the side protrusions 213 with the side gap of the hanger body 1, together with the engagement of the second protrusion 211 in the middle with the first groove 112, further avoids problems such as skewing and loosening of the hook 2 during use. Moreover, the addition of the side protrusions 213 disperses the stress points of the mounting part 11, making the stress distribution more uniform when the hook 2 is connected to the hanger body 1, reducing the risk of damage to the paper material due to local overload, and extending the overall service life of the paper-plastic hanger.
[0045] In this embodiment, the assembly hole 113 is located in the center of the top surface of the hanger body 1 and is in the shape of a strip. The strip hole located in the center of the top surface of the hanger body 1 provides a central axis positioning reference for the assembly of the hook 2, ensuring that the hook 2 is precisely aligned with the concave and convex structure of the hanger body 1 when it is inserted vertically; the central strip hole makes the force center of the hook 2 coincide with the center of gravity of the hanger body 1, forming a symmetrical stress distribution when clothes are hung, thus improving the overall load-bearing stability.
[0046] Example 2
[0047] like Figure 4 and Figure 5 As shown, a high-strength paper-plastic hanger with a detachable hook includes a hanger body 1 and a hook 2. The rest of the structure is the same as in Embodiment 1, but based on the structure of Embodiment 1, the hook 2 is also provided with a limiting tongue 22 on its side. The upper side of the limiting tongue 22 is a gentle surface 21, and the lower side of the limiting tongue 22 is a steep surface 222. After the hook 2 is inserted into the mounting hole 113 of the hanger body 1, the lower side of the limiting tongue 22 forms a one-way wedge-tight structure with the hole wall of the hanger body 1, which effectively prevents the hook 2 from accidentally coming out.
[0048] The gap width of the mounting hole 113 in the hanger body 1 is greater than the thickness of the hook 2 but less than the maximum thickness of the limiting latch 22. The limiting latch 22 and the hook 2 are integrally molded. Therefore, the limiting latch 22 is made of paper-plastic material and is elastic. Since the upper side of the limiting latch 22 is a flat surface 21, when the hook 2 passes through the mounting hole 113 from bottom to top, the edge of the mounting hole 113 applies pressure to the flat surface 21. Based on the elasticity of the paper-plastic material, the limiting latch 22 deforms, its thickness decreases, and it can smoothly pass through the mounting hole 113 to complete the assembly of the hook 2 and the hanger body 1. After the hook 2 is assembled, no external force is applied to the limiting latch 22, and the limiting latch 22 returns to its original shape due to the elasticity of the paper-plastic material. Furthermore, because the lower side of the limiting tongue 22 is a steep surface 222, the limiting tongue 22 will form a blockage after the deformation is restored. Since the gap width of the assembly hole 113 is less than the maximum thickness of the limiting tongue 22, under normal use, the hook 2 will not detach downward from the clothes hanger body 1 due to gravity or slight external force.
[0049] In this embodiment, the upper side of the limiting tongue 22 forms a gentle surface 21 with an angle of 10° to 30° with the horizontal plane; the lower side of the limiting tongue 22 forms a steep surface 222 with an angle of 45° to 90° with the horizontal plane.
[0050] like Figure 6 As shown, in this embodiment, the hook 2 includes a first hook 2 body and a second hook 2 body. The first hook 2 body and the second hook 2 body are two symmetrical structures cut and pressed from the same cardboard, reducing the process steps of traditional multi-part assembly, improving processing efficiency, and reducing production costs. The top ends of the first hook 2 body and the second hook 2 body are connected and can be folded, so that the hook 2 is in a flat unfolded form in the unassembled state, with a thickness of only 1 / 2 of that in the covered state.
[0051] Example 3
[0052] like Figure 1 As shown, a high-strength paper-plastic hanger with a detachable hook includes a hanger body 1 and a hook 2. The remaining structure is the same as in Embodiment 2, but based on the structure of Embodiment 2:
[0053] The top wall of the shoulder section of the main body 1 of the hanger is provided with a first structural reinforcing groove 12, which is arranged along the length of the shoulder. The reinforcing groove simulates the hollow prismatic structure of a bird's wing bone. By pressing longitudinal grooves into the top wall, the cross-section of the shoulder forms an "M-shaped" or "W-shaped" wavy profile. When the shoulder is subjected to vertical load, the protruding ridges on both sides of the groove act as the main load-bearing units, resisting deformation through the bending stiffness of the material; thus increasing the bending stiffness of the shoulder by about 50%, effectively preventing the shoulder from collapsing or breaking due to load.
[0054] The side wall of the shoulder end of the hanger body 1 is provided with several second structural reinforcement grooves 13, and the second structural reinforcement grooves 13 are arranged perpendicular to the length direction of the shoulder. The second structural reinforcement grooves 13 form a transverse rib effect at the shoulder end, improving the local resistance to deformation.
[0055] This invention relates to a paper-plastic clothes hanger, which incorporates waterproofing and reinforcing agents during the manufacturing process. This ensures the finished product possesses a certain degree of moisture resistance and short-term waterproofing, and also exhibits a hardness exceeding that of ordinary paper-plastic products. The paper-plastic clothes hanger can be manufactured using either a wet pressing or a dry pressing process.
[0056] A. Wet pressing process: The aqueous slurry is vacuum-filtered through a forming mold to form a wet blank with a moisture content of 35%. The wet blank is placed in a shaping mold and dried and shaped under high temperature and pressure. Finally, excess material is removed in a trimming mold to achieve accurate design dimensions and a clean appearance.
[0057] B. Dry pressing process: The aqueous slurry is vacuum-filtered through a forming mold to form a wet blank with a moisture content of 35%. The wet blank is then dried by a drying system or naturally. It is then shaped under high temperature and pressure using a forming mold. Finally, excess material is removed in a trimming mold to achieve accurate design dimensions and a clean appearance.
[0058] Example 4
[0059] like Figure 7 As shown, a high-strength paper-plastic hanger with detachable hooks includes a hanger body 1 and a hook 2. The rest of the structure is the same as in Embodiment 3, but based on the structure of Embodiment 3: the hanger body 1 is equipped with an inner liner 3. After the hook 2 is assembled, the inner liner 3 is inserted into the interior of the hanger body 1 from bottom to top. The four corners of the top surface of the inner liner 3 are designed with arc-shaped grooves 31 that are adapted to the four first protrusions 111 inside the hanger body. After the inner liner 3 is installed in place, the middle position of its top surface can hold the hook 2, thereby making the hook 2 firmly fixed in the interior space of the hanger body 1.
[0060] This embodiment further enhances the structural strength of the hanger body 1 and extends the service life of the paper-plastic hanger by adding an inner lining 3.
[0061] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0062] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
