Abstract
Description
Technical Field
[0001] This utility model relates to the field of optical fiber technology, specifically to an emergency repair and replacement box for optical cables. Background Technology
[0002] The communication box features a lightweight, sealed, and waterproof design. The outer shell is made of high-strength, corrosion-resistant plastic and is secured using a two-part structure and movable buckles. Sealing at the joints with adhesive strips ensures environmental adaptability. Internally, it employs a multi-layered fiber optic tray that can accommodate up to 24 fibers, supporting rapid insertion and securing of emergency fiber optic cable terminations, significantly improving emergency repair efficiency. Its technical features include low insertion loss, stable operation, vibration resistance, and a complete set of tools, making it easy for single or two-person transport and meeting the rapid response needs in complex environments.
[0003] Because optical cables are inherently fragile, they are easily affected by external forces during transport, which can cause them to break during bending and render them unusable. Furthermore, the winding method cannot be used for double-ended transmission of electrical wires, making it difficult to deploy optical cables on-site. Utility Model Content
[0004] In view of the shortcomings of the existing technology, this utility model provides an emergency repair and replacement box for optical cables.
[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0009] A sinking trough is set on the rotating drum to allow the main body of the optical cable to fit against the axis of the rotating drum;
[0010] The main body of the optical cable is threaded around the rotating drum, with one end extending to the outlet box and the other end passing through the circular surface of one side of the rotating drum to the other side of the circular surface of the rotating drum.
[0011] The receiving plate is flexibly set in the sinking trough and contacts the inner ring of the cylinder formed by the optical cable body;
[0012] When the optical cable body and the receiving plate are pulled out, the optical cable body presses the receiving plate and is pulled out from inside the shell.
[0013] Preferably, the angle between the wire threading direction of the outlet box and the tangent formed by the optical cable body and the cylindrical surface of the rotating drum is between ten and twenty degrees.
[0014] Preferably, the contact surface of the receiving plate and the cable body is arc-shaped.

[0027] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.
[0028] Example
[0029] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the optical cable emergency repair replacement box includes a housing 1 with a circular inner cavity;
[0030] Outlet box 2, located on one side of housing 1, is used for outputting optical fiber;
[0031] Rotating cylinder 3 rotates coaxially on the inner wall of housing 1, and the cross-section of rotating cylinder 3 is an "I" shape rotated 90 degrees, with circular surfaces on both sides;
[0032] The sinking trough 31 is opened on the rotating drum 3 to allow the optical cable body 4 to fit along the axis of the rotating drum 3;
[0033] The optical cable body 4 is threaded around the rotating drum 3, with one end extending to the outlet box 2 and the other end passing through the circular surface of one side of the rotating drum 3 to the other side of the circular surface of the rotating drum 3.
[0034] The receiving plate 6 is flexibly set in the sinking trough 31 and contacts the inner ring of the cylinder formed by the optical cable body 4.
[0035] When the optical cable body 4 and the receiving plate 6 are pulled out, the optical cable body 4 presses the receiving plate 6 and is pulled out from inside the housing 1.
[0036] Due to its unique structure, optical fiber cables differ from electrical cables in that they are difficult to bend significantly, making them difficult to carry during use. In practice, measurements are taken by connecting the existing optical fiber cable to both sides of the original cut point of the optical fiber cable to be replaced using cold splice 9. Therefore, the optical fiber cable needs to have a cable retraction and release function on both sides.
[0037] During the use of this product, the rotating drum 3 rotates in conjunction with the handle 5, allowing one end of the optical cable body 4 to extend from the position of the outlet box 2 by rotation. The other end of the optical cable body 4 rotates together with the rotating drum 3. When the extended length of the optical cable body 4 is sufficient, the other end of the optical cable body 4 located on the circular surface of the rotating drum 3 is pulled.
[0038] In daily life, it is known that, in order to pursue the maximum winding length, the rope is usually arranged in the form of layer by layer covering, that is, the rope is repeatedly arranged in the circumferential side of the cylinder formed by the already wound rope, and then the end of the optical cable body 4 located at one end of the rotating drum 3 is located closest to the cylindrical surface of the rotating drum 3, that is, in the innermost layer of the wound optical cable.
[0039] When the end of the optical cable body 4 located at the circular surface of the rotating drum 3 is manually pulled, the part of the optical cable is pressed against the receiving plate 6, and the receiving plate 6 is radially moved to the deepest part of the sinking groove 31, and then the space formed by the sinking of the receiving plate 6 forms a space for the extension of the port of the optical cable body 4, so that the adapter has the effect of double-head take-up and pay-off, and it needs to be supplemented that the optical cable body 4 located at the circular surface of the rotating drum 3 extends outward according to the winding thread tendency.
[0040] The included angle between the threading direction of the outlet box 2 and the tangent line formed by the optical cable body 4 and the cylindrical surface of the rotating drum 3 is in the range of ten to twenty degrees, so as to prevent the tangent line from being too large to cause damage to the optical cable.
[0041] The contact surface between the receiving plate 6 and the optical cable body 4 is arc-shaped, so as to better receive the inner cylindrical surface of the cylinder formed by the winding of the optical cable body 4.
[0042] The rotating drum 3 is rotatably connected with an arc-shaped handle 5, and the handle 5 is provided with a recess for covering the side port of the optical cable body 4, so as to protect one end of the optical cable body 4.
[0043] The outlet box 2 is provided with a cover 21 for covering the other side of the optical cable body 4, and the shell 1 is provided with a protection ring 11 surrounding the handle 5, and the cover 21 protects the other end of the optical cable body 4.
[0044] A plurality of clamping plates 10 are fixedly connected to one side of the shell 1, and a terminal box 7 is slidably connected to the clamping plate 10, and a plurality of clamping blocks 8 for clamping the cold connector 9 are connected in the terminal box 7, and the terminal box 7 is provided with a clamping recess which is the same as the clamping plate 10, so that the cold connector 9 can be better accessed.
[0045] The technical scope of the utility model is not limited to the content in the above description, and those skilled in the art can make various deformations and modifications to the above embodiments without departing from the technical thought of the utility model, and these deformations and modifications should all belong to the protection scope of the utility model.
