Description
Technical Field
[0001] This utility model relates to the field of packaging technology, and in particular to an escape ladder frame packaging box. Background Technology
[0002] As an important piece of emergency rescue equipment, the integrity and reliability of escape ladders during storage and transportation are crucial. To ensure that escape ladders are not damaged before being delivered to users, they are usually sealed and protected in sturdy packaging boxes.
[0003] In current packaging practices, to secure heavy and irregularly shaped escape ladders and prevent them from shaking and colliding inside the packaging box, the common practice is to add additional securing structures inside the ordinary cardboard box. These securing structures are usually composed of wooden blocks, foam plastic, or multiple separate pieces of thick cardboard. However, while using wooden blocks as securing components offers high strength, it significantly increases the overall weight and material cost of the packaging, making it difficult to control the economics of handling and transportation.
[0004] While materials like foam plastics are lightweight, their molding requires specialized molds, resulting in high upfront costs for non-mass-produced products. Furthermore, foam materials have poor environmental friendliness, contradicting the trend towards green packaging. Conversely, simply stacking or splicing multiple individual cardboard pieces results in limited structural strength and stability, making it difficult to form a reliable overall support frame. This makes the structure prone to failure under the impact and vibration of heavy escape ladders, failing to provide effective protection.
[0005] Therefore, this utility model proposes an escape ladder frame packaging box to address the shortcomings of the prior art. Utility Model Content
[0006] In view of the problems of existing escape ladder frame packaging boxes, such as being bulky, costly, having complex internal fixing structures, and failing to provide stable and reliable support, this utility model aims to provide an escape ladder frame packaging box with an improved structure that can effectively solve the above problems.
[0007] This utility model provides an escape ladder frame packaging box, including a box body and an integrally formed frame assembly fixedly connected to the inside of the box body.
[0008] The keel assembly includes a keel plate, the sidewall of which is folded and connected to a limit block via a pre-set indentation line. A partition plate is vertically fixed to the bottom surface of the keel plate, and a support plate is fixedly connected to one end of the partition plate away from the keel plate. The other end of the support plate is inclinedly connected to the bottom surface of the keel plate, so that the partition plate and the support plate together form a triangular support structure.
[0009] Furthermore, the keel assembly also includes an auxiliary plate, one side of which is fixedly connected to the keel plate, while the other side is attached to the inner wall of the box. Through the structural combination of the above components, a lightweight and high-strength internal support frame is formed.
[0010] In a preferred embodiment, the aforementioned partition plate, support plate and keel plate work together to enclose a first receiving cavity inside the keel assembly. The spatial structure of the first receiving cavity is specifically designed to house the main body of the escape ladder.
[0011] Furthermore, the auxiliary plate, the limiting block, and the inner wall of the box cooperate with each other to define the second receiving cavity. This second receiving cavity is used to classify and store the scattered parts of the escape ladder, thereby avoiding mutual wear and tear between the main body and the parts.
[0012] In one specific manufacturing process, the limiting block is not an independent component, but is formed by directly folding a local area of the keel plate along a preset indentation line after being processed by die-cutting, thus realizing the integration of the structure and simplifying the production and assembly process.
[0013] To ensure the stability of the keel assembly within the box, the top surface of the partition plate is tightly abutted against one inner wall of the box, while the keel plate abuts against the other opposite inner wall of the box. This bidirectional abutment method securely fixes the keel assembly within the box.
[0014] As a preferred material, the keel assembly is preferably made of high-strength corrugated cardboard to minimize the overall weight of the packaging and reduce material costs while ensuring support strength.
[0015] To improve the ease of use of the packaging box, a through hole is provided on the side wall of the box body. The through hole is designed to insert and fix a handle, making it convenient for manual carrying and handling.
[0016] To form a complete packaging unit, the packaging box also includes a lid that covers the top opening of the box, providing dust and moisture protection for the escape ladder stored inside.
[0017] This utility model has the following beneficial effects: 1. In this utility model, by using an integrated cardboard frame assembly to replace the traditional wooden or plastic fixing liner, the problem of the existing escape ladder packaging box being bulky and having high production costs is solved, achieving a lightweight and low-cost packaging effect, which is convenient for handling and storage.
[0018] 2. In this utility model, by setting up a triangular support structure composed of partition plates and support plates working together, and by using limiting blocks to tightly limit the escape ladder, the problems of insufficient load-bearing capacity, poor fixing effect, and easy shaking and damage of products during transportation in existing packaging solutions are solved, achieving the technical effect of stable structure, reliable load-bearing capacity, and good protection effect.

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. Example
[0022] Please refer to Figures 1 to 4 This utility model provides an escape ladder frame packaging box, which aims to solve the problems of existing escape ladder packaging boxes using wooden or plastic linings, resulting in bulky overall weight, high cost, complex internal fixing structure, and inability to effectively divide and store items.
[0023] like Figure 1 and Figure 2 As shown, the escape ladder keel packaging box includes a box body 1 and a keel assembly 4 fixedly connected inside the box body 1; the box body 1 serves as the load-bearing foundation of the entire packaging box, providing installation space for the internal keel assembly 4 and escape ladder 5; the keel assembly 4 is used to form a lightweight and structurally stable internal support frame inside the box body 1. Specifically, refer to Figure 3 and Figure 4 The keel assembly 4 includes an integrally formed keel plate 41. The side wall of the keel plate 41 is folded and connected to a limiting block 42 for restricting the position of the escape ladder 5 via a pre-set indentation line. The core support structure of the keel assembly 4 consists of a partition plate 43 and a support plate 44. The partition plate 43 is vertically fixed to the bottom surface of the keel plate 41. One end of the support plate 44 is fixedly connected to the end of the partition plate 43 away from the keel plate 41. The other end of the support plate 44 is inclined to the bottom surface of the keel plate 41. Through this connection method, the partition plate 43 and the support plate 44 together form a stable structure. The triangular support structure further enhances the overall structural tightness. The keel assembly 4 also includes an auxiliary plate 45, one side of which is fixedly connected to the keel plate 41, and the other side is attached to the inner wall of the box body 1. The packaging box also includes a box lid 2, which covers the top opening of the box body 1 to seal and protect the inside of the box body 1. For easy handling, a through hole 7 is provided on the side wall of the box body 1 for inserting and fixing the handle 3. In a preferred embodiment, the keel assembly 4 is made of cardboard and manufactured by an integrated folding molding process.
[0024] To solve the above-mentioned technical problems, the core of the technical solution of this embodiment lies in the specific structural cooperation and connection relationship formed between the keel plate 41, the limiting block 42, the partition plate 43, the support plate 44 and the auxiliary plate 45 inside the keel assembly 4. This structural cooperation relationship constructs a stable and partitioned accommodating space within the box 1.
[0025] Please refer to the following carefully. Figure 2 , Figure 3 and Figure 4The core structure is described in detail below: The keel assembly 4, through its structural combination within the box body 1, together encloses the first receiving cavity 6 and the second receiving cavity 46. The first receiving cavity 6 is used to house the main body of the escape ladder 5. It is composed of a partition plate 43, a support plate 44, and a keel plate 41. The partition plate 43, as a vertical support member, has its top surface abutting against one inner wall of the box body 1. The support plate 44, as an inclined support member, has its two ends fixedly connected to the partition plate 43 and the keel plate 41, respectively. The resulting triangular support structure provides high-strength support for the bottom of the escape ladder 5 body housed in the first receiving cavity 6, effectively preventing the packaging box from deforming due to load. Meanwhile, the limiting block 42 is formed by die-cutting a local area of the keel plate 41 and folding it inward. The folded surface closely abuts the side of the escape ladder 5, thereby restricting the lateral position of the escape ladder 5. The second receiving cavity 46 is defined by the auxiliary plate 45, the limiting block 42 and the inner wall of the box 1. This space is used to store the loose parts of the escape ladder 5. The auxiliary plate 45 is closely attached to the inner wall of the box 1 and fixedly connected to the keel plate 41. It fills the gap between the keel assembly 4 and the box 1 and forms the boundary of the second receiving cavity 46. This structural design ensures that the main body and parts of the escape ladder 5 are classified and stored separately, avoiding mutual collision and wear during transportation.
[0026] Based on the above embodiments, the present invention may further include the following preferred technical solutions: As a specific spatial layout scheme, the first accommodating cavity 6 is formed by the partition plate 43, the support plate 44 and the keel plate 41, and is specifically used to accommodate the main body of the escape ladder 5. The second accommodating cavity 46 is defined by the auxiliary plate 45, the limiting block 42 and the inner wall of the box 1, and is used to store the accessories of the escape ladder 5. This layout achieves effective isolation between the main body and the accessories. As a preferred molding method for the limiting block 42, the limiting block 42 is integrally molded directly from a local area of the keel plate 41. Specifically, its outline and fold lines are pre-formed through a die-cutting process, and then folded along the fold lines to a predetermined position. This method does not require additional components and simplifies the production process. To ensure the installation stability of the keel assembly 4 in the box 1, the top surface of the partition plate 43 is tightly abutted against one side of the inner wall of the box 1, while the keel plate 41 is also tightly abutted against the other opposite inner wall of the box 1. This bidirectional abutting structure makes the keel assembly 4 firmly embedded in the box 1. As a preferred material choice for the keel component 4, it adopts a high-strength corrugated cardboard structure. This material has the advantages of being lightweight and inexpensive while providing sufficient support strength. In order to improve the overall functionality and convenience of the packaging box, through holes 7 are provided on one side or opposite side walls of the box body 1. The connecting part of the handle 3 is inserted and fixed in the through hole 7, making it convenient for users to carry and move. In addition, the packaging box also includes a lid 2. The size of the lid 2 is adapted to the top opening of the box body 1 and covers it to form a closed storage space.
[0027] Working principle: During packaging, the one-piece molded keel assembly 4 is first placed inside the box body 1. The keel assembly 4, through its own structure including the keel plate 41, partition plate 43, support plate 44, and auxiliary plate 45, automatically forms a stable support frame and a preset accommodating space within the box body 1. Then, the main body of the escape ladder 5 is placed in the first accommodating cavity 6 formed by the partition plate 43 and support plate 44, and the accessories are stored in the second accommodating cavity 46 defined by the auxiliary plate 45 and the limiting block 42. At this time, the limiting block, which is folded out from the keel plate 41... 42 is closely pressed against the escape ladder 5 to restrict its lateral displacement; at the same time, the triangular support structure composed of the partition plate 43 and the support plate 44 effectively supports the weight of the escape ladder 5, ensuring the load-bearing stability of the packaging; the auxiliary plate 45 fills the gap between the keel component 4 and the inner wall of the box 1, further improving the overall structural stability. Finally, the box lid 2 is closed. The entire packaging box, through the synergistic effect of the internal keel component 4, provides comprehensive limiting, support and partition protection for the escape ladder 5, effectively solving the technical problems of traditional packaging being bulky and having poor fixing effect.
[0028] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
