Description

Technical Field

[0001] This utility model relates to the technical field of communication optical cable laying tools, and in particular to an optical cable junction box that facilitates high-level fiber splicing construction. Background Technology

[0002] During the installation and use of fiber optic junction boxes, it is necessary to splice the fiber optic cables entering the box with the pigtails inside the box. For conventional floor-mounted boxes, the operation is relatively easy and quick. However, some fiber optic junction boxes are installed at higher locations due to environmental constraints, requiring wall-mounted or pole-mounted installation. When the junction box is installed at a higher location, the difficulty and complexity of splicing the fiber optic cables inside the box increase significantly. Generally, the fiber optic cables and splice trays inside the box need to be removed first, spliced ​​on the ground, and then reinstalled inside the box. This back-and-forth operation can easily damage the optical fibers and accelerate the wear and tear on related components. Although performing splicing directly at a high location can largely solve these problems, it is extremely inconvenient at heights, reduces operational safety, and requires the use of tools such as splicing machines (which are heavy, at least 4 kg). Other auxiliary tools are also scattered, and there is no platform to temporarily place these tools at high locations. Therefore, the operational efficiency and safety are relatively low. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a fiber optic cable junction box that can temporarily place the installation tool when wall-mounted or pole-mounted, which helps to facilitate safe and rapid high-level construction and is convenient for high-level fiber splicing construction.

[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is: an optical cable junction box that facilitates high-level fiber splicing construction, including a junction box body, a pole mounting component arranged on one side of the junction box body, a splicing tray arranged inside the junction box body, a platform support base fixedly installed on the junction box body, a storage platform for placing fiber splicing tools rotatably mounted on the platform support base, and a platform limiting and retaining device provided between the storage platform and the platform support base; during fiber splicing operation, the platform limiting and retaining device keeps the storage platform in a horizontal state; after the fiber splicing operation is completed, the platform limiting and retaining device keeps the storage platform in an vertical state.

[0005] As a preferred technical solution, the platform support is fixedly installed at the bottom of the junction box.

[0006] As a preferred technical solution, the platform support base includes two parallel platform support beams, and the two sides of the storage platform are respectively provided with platform pivots corresponding to each of the platform support beams, and the platform pivots are rotatably engaged with the platform support beams.

[0007] As a preferred technical solution, the platform limiting and holding device includes at least one limiting push-pull rod disposed on the surface of the platform. An upper limiting hole and a lower limiting hole are provided on the side of the platform support corresponding to the limiting push-pull rod, and the upper limiting hole and the lower limiting hole are equidistant from the rotating assembly point of the platform on the same side. When the limiting push-pull rod is inserted into the upper limiting hole, the platform remains in an upright state; when the limiting push-pull rod is inserted into the lower limiting hole, the platform remains in a horizontal state.

[0008] As a preferred technical solution, the limiting push-pull rod is configured as an L-shaped structure.

[0009] As an improvement to the above technical solution, two pull rod insert sleeves are fixed on the surface of the storage platform. The limiting push-pull rod is movably inserted through the two pull rod insert sleeves. A pull rod return spring is fitted on the limiting push-pull rod located between the two pull rod insert sleeves, and the end of the pull rod return spring near the upper limit hole or the lower limit hole is fixed to the limiting push-pull rod.

[0010] As an improvement to the above technical solution, the platform is provided with a platform enclosure to prevent the fiber melting tool from slipping off.

[0011] Due to the adoption of the above technical solution, the optical cable junction box, which facilitates high-level fiber splicing construction, includes a junction box body. A pole mounting bracket is provided on one side of the junction box body. A splicing tray is provided inside the junction box body. A platform support base is fixedly installed on the junction box body. A storage platform for placing fiber splicing tools is rotatably mounted on the platform support base. A platform limiting and retaining device is provided between the storage platform and the platform support base. During fiber splicing operations, the platform limiting and retaining device keeps the storage platform in a horizontal state; after the fiber splicing operation is completed, the platform limiting and retaining device keeps the storage platform in an vertical state. This utility model has the following advantages: First, the optical cable junction box is installed and fixed at a high position on the pole using the pole mounting bracket. When introducing the optical cable for fiber fusion splicing, the platform is rotated to a horizontal position and held in place by the platform limiting and holding device. The fiber fusion tools, such as the fiber fusion machine, are placed on the platform for easy access, providing a temporary place to put the fiber fusion tools during breaks in use. After the fiber fusion splicing is completed, the platform limiting and holding device is released from its horizontal position, and the platform is rotated to an vertical position and held in place again by the platform limiting and holding device. The fiber fusion construction is convenient and safe, and helps to improve work efficiency. Attached Figure Description

Detailed Implementation

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments. In the following detailed description, only certain exemplary embodiments of the present invention are described by way of illustration. Undoubtedly, those skilled in the art will recognize that various modifications can be made to the described embodiments without departing from the spirit and scope of the present invention. Therefore, the drawings and description are illustrative in nature and not intended to limit the scope of the claims.

[0020] like Figures 1 to 4 As shown, the optical cable junction box, which facilitates high-level fiber splicing construction, is installed at a high position using a pole-mounted method. Specifically, it includes a junction box body 1, with a pole-mounted mounting component 2 installed on one side of the junction box body 1. The junction box body 1 contains conventional supporting components such as a splice tray 3 and an optical cable fixing seat. The pole-mounted mounting component 2 includes a pole beam, a tie rod, and locking bolts, etc., which, along with the splice tray 3 and the optical cable fixing seat, are well-known to those skilled in the art and will not be described in detail here. In this embodiment, the junction box body 1 is fixedly installed on the pole using the pole-mounted mounting component 2. To ensure the stability of the installation, at least two sets of the pole-mounted mounting component 2 are generally installed on the junction box body 1.

[0021] A platform support is fixedly installed on the junction box 1. A storage platform 4 for placing fiber splicing tools is rotatably mounted on the platform support. A platform limiting and retaining device is provided between the storage platform 4 and the platform support. When performing fiber splicing operations, the platform limiting and retaining device keeps the storage platform 4 in a horizontal state, which is used to temporarily place the tools used, such as fiber splicing machines and fiber strippers, during fiber splicing connections. After the fiber splicing operation is completed, the platform limiting and retaining device keeps the storage platform 4 in an upright state, making the storage platform 4 parallel to the surface of the junction box 1, so that the storage platform 4 can be retracted to prevent the junction box 1 from being subjected to increased stress in rainy or snowy weather.

[0022] The platform support is fixedly installed at the bottom of the junction box 1, and the platform support includes two parallel platform support beams 5. Platform pivots 6 are respectively provided on both sides of the storage platform 4 corresponding to each of the platform support beams 5, and the platform pivots 6 are rotatably engaged with the platform support beams 5. In this embodiment, when the storage platform 4 is in an upright or horizontal state, it is located on the front side of the junction box 1, aligning with the opening of the junction box 1 to facilitate fiber optic splicing. Furthermore, the storage platform 4 is provided with platform barriers 7 around its perimeter to prevent fiber optic splicing tools from slipping, providing a certain degree of restraint and blocking effect on tools placed on the surface of the storage platform 4, making tool placement safer and more reliable.

[0023] The platform limiting and holding device includes at least one limiting push-pull rod 8 disposed on the surface of the storage platform 4. The limiting push-pull rod 8 is configured with an L-shaped structure to facilitate limiting cooperation with the hand, making the push-pull operation more convenient. On the side of the platform support base, corresponding to the limiting push-pull rod 8, there are upper limiting holes 9 and lower limiting holes 10 for cooperation. The upper limiting holes 9 and lower limiting holes 10 are equidistant from the rotating assembly of the storage platform 4 on the same side, allowing the limiting push-pull rod 8 to adapt to the rotation of the storage platform 4 and smoothly achieve limiting at the corresponding position. Specifically, when the limiting push-pull rod 8 is inserted into the upper limit hole 9, the storage platform 4 is limited and kept in an upright state, preventing the storage platform 4 from rotating downwards on its own when not in use, thereby avoiding collision vibrations caused by its up-and-down movement when blown by the wind, which helps to protect the storage platform 4 and the firmness of the fiber optic splice inside the junction box 1; when the limiting push-pull rod 8 is inserted into the lower limit hole 10, the storage platform 4 is limited and kept in a horizontal state, so as to provide sufficient support for the storage platform 4 and the tools placed on its surface.

[0024] like Figure 5As shown, two pull rod insert sleeves 11 are fixed to the surface of the storage platform 4. The limiting push-pull rod 8 is movably inserted through the two pull rod insert sleeves 11 to realize the installation of the pull rod insert sleeves 11 and the push-pull guidance. A pull rod return spring 12 is fitted on the limiting push-pull rod 8 located between the two pull rod insert sleeves 11, and the end of the pull rod return spring 12 near the upper limit hole 9 or the lower limit hole 10 is fixed to the limiting push-pull rod 8. The pull rod return spring 12 enables the limiting push-pull rod 8 to be stably inserted and engaged with the upper limit hole 9 or the lower limit hole 10, thereby playing a role in preventing detachment, making it more reliable, and making the storage platform 4 more effective in maintaining horizontal or vertical positions.
