Description

Technical Field

[0001] This utility model relates to the field of optical fiber equipment accessories technology, and in particular to an easily disassembled optical fiber box. Background Technology

[0002] With the rapid development of communication networks, optical fiber, as the core carrier of information transmission, has led to an increasing demand for the deployment and maintenance of related equipment. In various optical fiber access scenarios, fiber optic boxes, as important devices for protecting and managing fiber optic connectors, are widely used in various environments such as computer rooms, corridors, and outdoors. However, traditional fiber optic boxes still have some problems that urgently need to be solved in practical use.

[0003] Currently, most fiber optic boxes adopt a fixed or simple snap-fit ​​structure. While these can meet basic functional requirements, they often present difficulties in disassembly during equipment maintenance, upgrades, or replacement of internal modules. Specifically, traditional structures lack effective positioning and limiting mechanisms, causing the inner box to wobble during the pulling and unpulling process. This not only affects the stability of the internal fiber optic components but may also cause interface loss due to repeated friction. Furthermore, existing connection methods mostly rely on screws or single elastic elements, making installation and disassembly cumbersome, especially in confined spaces or high-altitude work environments. This hinders rapid equipment adjustment and maintenance, reducing operational efficiency.

[0004] To address the aforementioned issues, while the industry has attempted improvements through optimizing guide rail structures or adding auxiliary locking devices, shortcomings such as complex structures, high costs, and insufficient reliability remain. Therefore, developing a new type of fiber optic box that combines convenient disassembly, stable support, and efficient installation is crucial for enhancing the maintainability and adaptability of fiber optic systems. The technical solution proposed in this case, through an innovative design of fastening holes and J-shaped hooks, aims to solve problems such as inconvenient disassembly and unstable positioning in existing technologies, providing an effective solution for the modular design and rapid maintenance of fiber optic boxes. It is evident that existing technologies still require improvement and enhancement. Utility Model Content

[0005] In view of the shortcomings of the prior art, the purpose of this utility model is to provide an easily disassembled fiber optic box to solve one or more problems existing in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an easily disassembled fiber optic box, comprising a fiber optic outer shell and a drawer inner box that is pulled out and disposed within the fiber optic outer shell, further comprising a fastening hanging hole and a J-shaped hook. The fastening hanging hole is provided on the back plate of the drawer inner box, and the fastening hanging hole is disposed near the bottom plate of the drawer inner box. The J-shaped hook comprises a supporting part, a hooking part and a mounting part connected in sequence. The supporting part and the mounting part are arranged vertically. The supporting part is located above the fastening hanging hole and abuts against the back plate. The mounting part is fixed to the inner wall plate of the fiber optic outer shell.

[0007] In one embodiment of the present invention, a matching slider and a slide rail are further included. The slide rail is fixed on the side wall of the inner drawer box, and the slider is correspondingly disposed on the inner wall of the optical fiber shell and slides in cooperation with the slide rail.

[0008] In one embodiment of the present invention, a cable opening is provided on the front side of the inner drawer box, and a socket panel is detachably installed at the cable opening. The socket panel has a plurality of fiber optic sockets arranged in a matrix.

[0009] In one embodiment of this utility model, the number of cable openings is multiple, and the multiple cable openings are arranged in rows at intervals along the horizontal direction.

[0010] In one embodiment of the present invention, a support plate is further included, which is fixed to the front side of the inner drawer box. The support plate is located below the socket panel and extends horizontally forward.

[0011] In one embodiment of the present invention, a fixing plate is connected to the side wall of the optical fiber housing by screws, and the fixing plate is detachably connected and fixed to the socket panel by screws.

[0021] This utility model provides an easily disassembled fiber optic box. To make the purpose, technical solution, and effects of this utility model clearer and more explicit, the following detailed description is provided with reference to the accompanying drawings and embodiments. In the description of this utility model, it should be understood that the terms "up," "down," "left," and "right," etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description; they should not be construed as limitations on this utility model. Furthermore, the terms "installation," "connection," etc., should be interpreted broadly, and those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0022] Please see Figures 1 to 3 This utility model provides an easily disassembled fiber optic box, including a fiber optic outer shell 1 and a drawer inner box 2 that is pulled out and disposed within the fiber optic outer shell 1. It also includes a fastening hanging hole 3 and a J-shaped hook 4. The fastening hanging hole 3 is provided on the back plate of the drawer inner box 2 and is located near the bottom plate of the drawer inner box 2. The J-shaped hook 4 includes a supporting part 41, a hook part 42 and a mounting part 43 connected in sequence. The supporting part 41 and the mounting part 43 are arranged vertically. The supporting part 41 is located above the fastening hanging hole 3 and abuts against the back plate. The mounting part 43 is fixed to the inner wall plate of the fiber optic outer shell 1.

[0023] In this embodiment, please refer to Figure 3 The fastening hole 3 is located at the corner where the back panel and bottom panel of the drawer inner box 2 meet. This corner location also helps reduce the space occupied inside the drawer inner box 2, providing greater flexibility for the arrangement of fiber optic devices.

[0024] In addition, the system includes matching sliders and slide rails 5. The slide rails 5 are securely mounted on both side walls of the drawer inner box 2. These slide rails are made of high-strength metal and have been finely polished to ensure smooth sliding. Correspondingly, the sliders are precisely mounted on the inner wall of the fiber optic housing 1. The sliders contain wear-resistant ball bearings, enabling a stable sliding fit with the slide rails 5. This precisely matched sliding structure design not only ensures the smooth movement of the drawer inner box 2 within the fiber optic housing 1 but also effectively reduces frictional resistance and extends service life.

[0025] The front side of the drawer inner box 2 has a cable opening 6, and a socket panel 7 is detachably installed at the cable opening 6. The socket panel 7 has several fiber optic sockets arranged in a matrix on it. To lock the socket panel 7, a fixing plate 9 is connected to the side wall of the fiber optic housing 1 by screws. The fixing plate 9 is detachably connected and fixed to the socket panel 7 by screws. For ease of operation, the socket panel 7 can be disassembled and installed without the need for additional tools; the user only needs to loosen the fixing screws to easily complete the replacement or maintenance work. This modular design not only improves the convenience of use but also significantly reduces maintenance costs. Specifically, there are multiple cable openings 6, which are arranged in rows at intervals along the horizontal direction. In this embodiment, there are three cable openings 6.

[0026] It also includes a support plate 8 fixed to the front side of the drawer inner box 2, which is located below the socket panel 7 and extends horizontally forward. To further improve ease of operation, the upper surface of the support plate 8 is designed with anti-slip texture to prevent the fiber optic socket on the socket panel 7 from slipping due to external force. At the same time, the front edge of the support plate 8 is rounded, which is both aesthetically pleasing and safe, reducing the risk of injury to the user during operation.

[0027] A cable clamp 10 is provided on the bottom plate of the drawer inner box 2. The cable clamp 10 is integrally stamped from the bottom plate of the drawer inner box 2. Multiple cable clamps 10 are provided, evenly distributed along the length of the bottom plate to ensure that the cables remain neat and orderly within the drawer inner box 2. Furthermore, the inner side of the cable clamp 10 is provided with an anti-slip pad to effectively prevent the cables from loosening or shifting during use.

[0028] In actual use, in its initial state, the fiber optic housing 1 has a hollow cavity structure, providing space for the installation of the drawer inner box 2. The J-shaped hook 4 has been pre-fixed to the inner wall of the fiber optic housing 1 through its mounting part 43, and the supporting part 41 of the J-shaped hook 4 is perpendicular to the mounting part 43. At this time, the drawer inner box 2 is independent of the fiber optic housing 1, and a fastening hole 3 adapted to the J-shaped hook 4 is reserved on its back plate near the bottom plate.

[0029] During installation, the operator holds the drawer inner box 2 and aligns it with the opening of the fiber optic outer shell 1, ensuring the back panel of the drawer inner box 2 faces the side where the J-shaped hook 4 is located inside the fiber optic outer shell 1. Then, the drawer inner box 2 is pushed into the fiber optic outer shell 1. During this process, the operator adjusts the position of the drawer inner box 2 so that the holding part 41 of the J-shaped hook 4 gradually approaches the fastening hole 3 on the back panel of the drawer inner box 2. When the holding part 41 aligns with the fastening hole 3, the drawer inner box 2 is lifted upwards and pushed further until the holding part 41 passes through the fastening hole 3. As the drawer inner box 2 is pushed further, the hook part 42 gradually hooks onto the back panel of the drawer inner box 2. Simultaneously, after passing through the fastening hole 3, the holding part 41 adheres to the inner side of the back panel of the drawer inner box 2, forming a supporting force. This ultimately achieves stable installation of the drawer inner box 2 inside the fiber optic outer shell 1. At this point, the drawer inner box 2 cannot slide or come out freely, and its interior can be used to place and connect fiber optic components.

[0030] During daily use, the J-shaped hook 4's supporting part 41 continuously abuts against the inside of the drawer inner box 2's back panel, and the hook part 42 tightly hooks the back panel. The double fixing structure formed by the two can effectively limit the displacement of the drawer inner box 2. Even if it is subjected to slight external force collision or vibration, the drawer inner box 2 can still maintain a stable position inside the fiber optic housing 1, ensuring that the internal fiber optic connection is not affected and guaranteeing the stability of fiber optic signal transmission.

[0031] When disassembly is required for inspection, maintenance, or replacement of internal fiber optic components, the operator simply applies an upward force to the drawer inner box 2, causing the back panel of the drawer inner box 2 to separate from the hook portion 42 of the J-shaped hook 4, releasing the hook portion 42 from its grip on the back panel. Then, the drawer inner box 2 is pulled outwards. At this time, the retaining part 41 gradually disengages from the fastening hole 3. As the drawer inner box 2 is continuously pulled outwards, it can eventually be completely removed from the fiber optic outer shell 1, allowing the operator to process the internal components. After processing, the drawer inner box 2 can be reinstalled back into the fiber optic outer shell 1 following the same installation steps, enabling the fiber optic box to be reused.

[0032] In summary, this utility model's easily disassembled fiber optic box, through the innovative design of fastening holes 3 and J-shaped hooks 4 working in synergy, constructs a fiber optic box structure that combines efficient assembly and disassembly with stable support. In actual use, when inserting the drawer inner box 2 into the fiber optic outer shell 1, the operator must simultaneously perform a combined upward lifting and horizontal pushing action. At this time, the holding part 41 of the J-shaped hook 4 precisely embeds into the fastening holes 3 near the bottom plate on the back plate, forming a downward pressing torque, causing the drawer inner box 2 to automatically lock in its working position after being fully pushed in. In the reverse operation, by simultaneously applying the combined force of upward pulling and horizontal dragging, the limiting constraint of the holding part 41 can be overcome to achieve rapid separation. This linkage operation avoids the lateral displacement problem easily caused by traditional slide rail structures and significantly improves the connection strength through physical interlocking. Compared to conventional designs that rely solely on elastic latches or threads for fixation, this solution achieves superior seismic performance through multi-point contact in three-dimensional space, while simplifying the maintenance process—module replacement can be completed without tools. Especially in high-altitude operations or confined spaces, precise alignment and rapid disassembly can be performed with one hand, significantly reducing the workload of maintenance personnel. Furthermore, the precise design of the fit clearance between the J-shaped hook 4 and the fastening hole 3 ensures the stability of the drawer inner box 2 under vibration conditions while preventing accelerated wear due to interference fit, thus extending the equipment's service life. Therefore, this invention effectively overcomes the various shortcomings of existing technologies and possesses high industrial applicability.

[0033] It is understood that those skilled in the art can make equivalent substitutions or changes based on the technical solution and inventive concept of this utility model, and all such substitutions or changes should fall within the protection scope of this utility model.
