Description

Technical Field

[0001] This utility model belongs to the field of optical communication equipment technology, and in particular relates to an optical cable junction box. Background Technology

[0002] As a core infrastructure of modern information society, the stability and reliability of fiber optic communication networks are of paramount importance. Fiber optic junction boxes are indispensable key node devices in fiber optic access networks, widely deployed in outdoor environments to terminate, splice, distribute, and schedule trunk and distribution cables. They provide the physical basis for operators to flexibly manage, expand, and maintain fiber optic resources, and their rational design and ease of use directly affect the efficiency and cost of fiber optic network deployment and operation.

[0003] However, when performing on-site construction and maintenance of existing fiber optic junction boxes, construction personnel generally face the dilemma of insufficient operating space. Conventional fiber optic junction boxes are designed solely to accommodate and manage internal cables, completely neglecting to provide support for external operations. When technicians need to perform precision operations such as fiber splicing, end-face testing, and patch cord management, they are forced to place fusion splicers, tools, spare parts, and other items on damp or uneven ground, or carry auxiliary equipment such as folding tables, because the box itself does not provide any usable work surface. This operating method not only leads to a cluttered work site and increases the difficulty of finding and retrieving tools, but more seriously, the unstable operating environment can easily lead to fiber end-face contamination or decreased splicing quality, and may even damage expensive instruments and equipment due to accidental collisions or drops, posing significant operational inconvenience and safety hazards.

[0004] In summary, existing fiber optic junction boxes generally lack a stable operating platform integrated with the box itself that can be deployed as needed. This forces construction workers to perform precision operations in inconvenient and inefficient environments, affecting not only work efficiency and quality but also posing a potential threat to equipment safety and lifespan. Therefore, a pressing technical problem in this field is how to provide on-site construction workers with a convenient, stable, and reliable ready-to-use working platform without significantly increasing the manufacturing cost and external size of the junction box or relying on external auxiliary equipment. Utility Model Content

[0005] The purpose of this invention is to address the above-mentioned shortcomings and provide an optical cable junction box.

[0006] An optical cable junction box includes a box body and a door hinged to the box body, and further includes an operating platform mechanism disposed on the inner surface of the door, the operating platform mechanism comprising:

[0007] An operating platform is pivotally connected to the cabinet door so that it can rotate between an open position perpendicular to the cabinet door and a retracted position that conforms to the cabinet door.

[0008] A support assembly, connected between the door and the operating platform, for supporting the operating platform when it is in the unfolded position; and

[0009] A locking element is provided to releasably lock the operating platform in the retracted position when the operating platform is in the retracted position.

[0010] Furthermore, the support assembly includes two symmetrical and vertically fixed platform movable supports on the door, the bottom end of which is pivotally connected to the operating platform.

[0011] Furthermore, the support assembly also includes two symmetrical and vertically fixed sliding members and a sliding limit rod connected to the inner side of the platform's movable support; the sliding members have sliding grooves along their length; the free end of the sliding limit rod is slidably connected to the sliding groove, and the fixed end is pivotally connected to the side of the operating platform.

[0012] Furthermore, the operating platform flips from the retracted position to the unfolded position, and the free end of the sliding limit rod slides along the sliding groove. When the operating platform is in the unfolded position, a stable triangular support structure is formed by the sliding limit rod, the operating platform, and the platform movable bracket.

[0013] Furthermore, a limiting structure is provided at the end of the sliding groove. When the operating platform is in the unfolded position, the free end of the sliding limiting rod abuts against the limiting structure to prevent it from sliding further.

[0014] Furthermore, the sliding component and the platform movable support are integrally formed.

[0015] Furthermore, the locking element is a magnetic element.

[0016] Furthermore, the magnetic suction component is fixed to the upper part of the inner surface of the box door, and the operating platform is made of magnetic material or has a magnetic conductive part corresponding to the magnetic suction component on the upper part of the operating platform, so as to achieve locking by magnetic attraction in the retracted position.

[0017] Furthermore, the upper surface of the operating platform is a flat workbench for placing tools and equipment in the unfolded position.

[0018] Furthermore, the edge of the workbench is provided with a raised rim to prevent tools or equipment from slipping off.

[0019] The beneficial effects of this utility model are:

[0020] This utility model provides an optical cable junction box. By incorporating a pivotable operating platform mechanism inside the box door, it achieves the convenient function of "expanding when needed and retracting when not in use." In use, the operating platform can be quickly flipped and unfolded, and with effective support from the support components, it instantly forms a spacious, stable, and reliable work surface. Construction personnel can place fiber optic fusion splicers, testing instruments, and various tools directly on this platform for precise operations. This not only completely solves the environmental clutter and operational inconvenience caused by working on the ground or uneven surfaces, significantly improving the efficiency and quality of fiber optic splicing, line testing, and other tasks, but also provides a safe storage space for expensive equipment, reducing the risk of wear and damage caused by careless placement or accidental collisions. When not in use, the platform can be completely retracted and locked against the inside of the box door, without occupying additional internal space or increasing the external profile of the junction box. With its minimalist structure and extremely low cost, it perfectly solves the technical problem of the lack of an integrated, stable, and reliable work surface in existing optical cable junction boxes.

For the sake of simplicity, this document cannot exhaustively list all alternative technical features and implementation schemes included in this utility model.

[0026] This embodiment provides an optical cable junction box 100, including a box body 110 and a door 120 hinged to the box body 110, and also includes an operating platform mechanism 130 disposed on the inner surface of the door 120. The operating platform mechanism 130 includes:

[0027] The operating platform 131 is pivotally connected to the door 120 so that it can rotate between an unfolded position perpendicular to the door 120 and a retracted position that fits against the door 120.

[0028] Support assembly 132, connected between the door 120 and the operating platform 131, and used to support the operating platform 131 when it is in the unfolded position; and

[0029] Locking element 133 is used to releasably lock the operating platform 131 in the retracted position when the operating platform 131 is in the retracted position.

[0030] like Figure 1 , 2 As shown, the optical cable junction box 100 includes a box body 110 and a door 120 hinged to the box body 110. A complete operating platform mechanism 130 is also provided on the inner surface of the door 120. This operating platform mechanism 130 mainly consists of three parts: a movable operating platform 131, a support assembly 132 for supporting the operating platform 131, and a locking member 133 for fixing the operating platform 131 in a retracted state. Figure 2 and Figure 3 As shown, the operating platform 131 is pivotally connected to the door 120, allowing it to freely rotate between an extended position perpendicular to the door 120 and a retracted position flush against the door 120. A support assembly 132 is physically connected between the door 120 and the operating platform 131, providing stable support when the operating platform 131 is in the extended position. A locking element 133 reliably locks the operating platform 131 in the retracted position, preventing accidental shaking or opening.

[0031] In some embodiments, the support assembly 132 includes two symmetrical and vertically fixed platform movable supports 1321 mounted on the door 120, the bottom ends of which are pivotally connected to the operating platform 131.

[0032] In some embodiments, the support assembly 132 further includes two symmetrical and vertically fixedly connected sliding members 1322 and sliding limit rods 1323 to the inner side of the platform movable bracket 1321; the sliding members 1322 are provided with sliding grooves along their length direction; the free end of the sliding limit rod 1323 is slidably connected to the sliding groove, and the fixed end is pivotally connected to the side of the operating platform 131.

[0033] In some embodiments, the slider 1322 and the platform movable support 1321 are integrally formed.

[0034] Please see Figure 2 The support assembly 132 specifically includes two symmetrically arranged platform movable supports 1321, which are vertically fixed to the inner surface of the door 120. The bottom end of each platform movable support 1321 is pivotally connected to the operating platform 131. For guidance and support, the support assembly 132 also includes two symmetrical sliders 1322 and two sliding limit rods 1323. Each slider 1322 is vertically fixed to the inner side of the corresponding platform movable support 1321 and has a sliding groove along its length. In a preferred embodiment, to improve structural strength and simplify the manufacturing process, the sliders 1322 and the platform movable supports 1321 can be designed as an integrally formed structure. The fixed end of each sliding limit rod 1323 is pivotally connected to the side of the operating platform 131, and its free end is placed and fitted in the corresponding sliding groove, allowing it to slide along the groove.

[0035] In some embodiments, the operating platform 131 is flipped from the retracted position to the unfolded position, and the free end of the sliding limit rod 1323 slides along the sliding groove. When the operating platform 131 is in the unfolded position, a stable triangular support structure is formed by the sliding limit rod 1323, the operating platform 131 and the platform movable bracket 1321.

[0036] In some embodiments, a limiting structure is provided at the end of the sliding groove. When the operating platform 131 is in the unfolded position, the free end of the sliding limiting rod 1323 abuts against the limiting structure to prevent it from sliding further.

[0037] When the operating platform 131 needs to be used, the staff first puts the operating platform 131 back into its stowed state (e.g., Figure 3 Pull it outwards to disengage it from the locking element 133. Then, the operating platform 131 flips downwards about its pivot point with the door 120. During this process, the free end of the sliding limit rod 1323 slides downwards along the sliding groove on the slider 1322. When the operating platform 131 is fully flipped to the horizontal unfolded position (e.g., Figure 2The free end of the sliding limit rod 1323 slides precisely to the lower end of the sliding groove. At this point, to prevent the operating platform 131 from tilting excessively and to ensure its stability, a limiting structure is specially provided at the lower end of the sliding groove, and the free end of the sliding limit rod 1323 will firmly abut against this limiting structure. At this time, the rigid platform movable support 1321, the sliding limit rod 1323, and the operating platform 131 naturally form an extremely stable triangular support structure, thereby ensuring that the operating platform 131 can withstand sufficiently large weight, providing a reliable workbench for on-site construction.

[0038] In some embodiments, the locking element 133 is a magnetic element.

[0039] In some embodiments, the magnetic clasp is fixed to the upper part of the inner surface of the door 120, and the operating platform 131 is made of magnetic material or has a magnetic conductive part corresponding to the magnetic clasp on the upper part of the operating platform 131, so as to achieve locking by magnetic attraction in the retracted position.

[0040] In this embodiment, as Figure 2 As shown, the locking element 133 is a magnetic element. This magnetic element is fixed to the upper part of the inner surface of the door 120. Correspondingly, the operating platform 131 is made of a magnetic material such as iron, or an additional magnetic metal plate is provided at the corresponding position on its upper part. When the operating platform 131 is flipped upward to the retracted position, its upper part will approach and be firmly attracted by the magnetic element, thereby achieving a simple, reliable, and mechanically wear-free locking mechanism.

[0041] In some embodiments, the upper surface of the operating platform 131 is a flat workbench for placing tools and equipment in the unfolded position.

[0042] In some embodiments, the edge of the work surface is provided with a raised rim to prevent tools or equipment from slipping off.

[0043] To improve ease of use and security, such as Figure 2 As shown, the upper surface of the operating platform 131 is designed as a completely flat workbench, facilitating the stable placement of welding machines, tools, and other equipment. More preferably, a raised edging is integrally formed along the edge of the workbench. This simple edging structure effectively prevents round tools or precision equipment placed on the platform from rolling off due to accidental contact, further enhancing operational safety.

[0044] Working principle:

[0045] From retraction to unfolding: the operator pulls the operating platform 131, which is held by the magnetic chuck, outward and flips it downward. The sliding limit rod 1323 automatically slides along the sliding groove to the lower limit point, forming a stable triangular support. The process is completed in one go.

[0046] From unfolding to folding: The operator lifts the operating platform 131 upwards, and the sliding limit rod 1323 automatically slides back to the upper end along the sliding groove until the platform is completely against the inside of the door 120. The magnetic attachment automatically engages and locks the platform, completing the storage. The entire process requires no complicated operation, truly achieving "unfolding when needed and folding when not needed".

[0047] For those skilled in the art, other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations, but obvious variations or modifications derived therefrom are still within the scope of protection of the claims of this invention.
