Description

Technical Field

[0001] This utility model relates to the field of optical cable positioning technology, and in particular to a positioning device for laying out communication optical cables. Background Technology

[0002] In the construction of optical fiber cable laying, the optical cable route must be planned first and the cable must be positioned at key nodes such as corners, slopes, and crossings. Then, the optical cable is temporarily fixed and released in an orderly manner through the cable laying support device. The stability of the cable laying process directly determines the quality and service life of the optical cable. As a core auxiliary device, the cable laying support device must realize the dual functions of optical cable positioning and dynamic buffering.

[0003] Traditional cable laying supports often employ rigid clamping structures, where the optical cable is directly locked in place with bolts during positioning. While such devices can meet the basic positioning requirements, they lack buffering and adjustment capabilities. When instantaneous tension fluctuations occur during the laying process, the rigid structure cannot release the stress, easily leading to wear on the optical cable sheath and breakage of the fiber core. This problem of optical cable damage caused by sudden tension changes is particularly prominent in long-distance laying or construction in complex terrain.

[0004] Based on the above viewpoints, those skilled in the art have proposed a positioning device for laying out communication optical cables. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a positioning device for laying communication optical cables. This device effectively solves the defects of traditional rigid positioning through the sliding cooperation of the elastic positioning rod and the spring buffer structure. If the tension is too great during laying, the optical cable can drive the fixed plate to stretch the elastic positioning rod, avoiding damage to the optical cable caused by rigid locking.

[0006] To achieve the above objectives, the present invention provides the following technical solution: An adjustable communication optical cable laying support device includes: The pull plate has a ring-shaped structure and a through hole in the center for threading optical cables. A fixed plate is located on the front side of the pull plate and is connected to the pull plate by several elastic positioning rods; Both the pull plate and the fixed plate have slots for embedding the optical cable in their center, while the elastic positioning rod consists of a rod, a tube, and a spring connecting the two. The rod-shaped part of the elastic positioning rod slides on the inner wall of the tube-shaped part.

[0007] Preferably, the fixing plate includes an elastic fixing member connected to a plurality of elastic positioning rods, a nested ring fitted into the inner wall of the elastic fixing member, and a connecting outer ring fixed inside the nested ring, wherein the connecting outer ring is crescent-shaped and the annular part at its center has an inward deformation tendency.

[0008] Preferably, all of the aforementioned elastic positioning rods are fitted inside the pull plate.

[0009] Preferably, a spring force adjustment assembly is provided on the rear side of the tubular portions of the plurality of spring positioning rods for driving the tubular portions of the plurality of spring positioning rods to slide back and forth, wherein the spring force adjustment assembly includes: A spring-loaded limiting ring is slidably fitted to the rear side wall of the pull plate and fixedly connected to the tubular portion of several elastic positioning rods; An adjustment mechanism, located below the spring limit ring, is used to drive the spring limit ring to slide linearly inside the pull plate.

[0010] Preferably, the adjustment mechanism includes a bottom wedge block fixed to the lower side of the spring limiting ring, a threaded rod threaded to the bottom of the pull plate, a rotating head rotatably connected to the top of the threaded rod, and a wedge-shaped extrusion block fixed to the top of the rotating head, wherein the wedge-shaped extrusion block is adapted to the wedge-shaped surface of the bottom wedge block.

[0011] Preferably, the bottom of the pull plate is fixedly connected with a fixing clamp.

[0012] This utility model has the following beneficial effects: 1. This device effectively solves the shortcomings of traditional rigid positioning by using the sliding fit of the elastic positioning rod and the spring buffer structure. If the tension is too high during cable laying, the optical cable can drive the fixing plate to stretch the elastic positioning rod, avoiding damage to the optical cable caused by rigid locking; when the tension returns to normal, the spring automatically pulls back the optical cable, ensuring positioning accuracy. The crescent-shaped outer ring of the fixing plate has an inward deformation tendency, allowing the optical cable to adaptively hug and lock after insertion, improving positioning stability and adapting to optical cables of different diameters, reducing surface wear.

[0013] 2. This device utilizes an elastic adjustment component to precisely control the buffering force. Rotating the threaded rod pushes the bottom wedge block via the wedge-shaped compression block, causing the spring limit ring to slide and change the spring preload, meeting the tension requirements of different working conditions. The elastic positioning rod is embedded inside the pull plate, resulting in a compact structure and stable installation. Combined with the fixing clamp at the bottom of the pull plate, device positioning can be quickly completed. The overall design balances buffer protection, precise adjustment, and convenient installation, significantly improving cable laying efficiency and fiber optic cable safety.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Example, refer to Figures 1-4 An embodiment of this utility model provides an adjustable communication optical cable laying support device, comprising: a pull plate 1, which has a ring structure and a through hole for threading the optical cable at its center; and a fixed plate 2, which is disposed on the front side of the pull plate 1 and connected to the pull plate 1 by a plurality of elastic positioning rods 5; wherein both the pull plate 1 and the fixed plate 2 have slots for embedding the optical cable in their center, and the elastic positioning rods 5 are composed of rods, tubes and springs connecting the two, and the rod-shaped part of the elastic positioning rod 5 slides on the inner wall of the tube-shaped part. The support device uses the elastic positioning rod 5 to buffer the cable during the cable laying process, preventing the positioning structure from locking the optical cable and causing damage to the optical cable due to excessive tension during subsequent cable laying. In use, the optical cable positioning position is determined and the pull plate 1 is installed behind that position. Then, the optical cable is inserted into the slot between the pull plate 1 and the fixed plate 2. During the cable laying process, if the cable laying tension is large, the cable will be stretched along with the fixed plate 2 due to friction. When the tension is restored, the optical cable is pulled back by the elastic positioning rod 5, ensuring positioning accuracy while effectively preventing damage to the optical cable.

[0018] In an optional embodiment, the fixing plate 2 includes a spring-loaded fixing member 23 connected to the rod-shaped portions of a plurality of spring-loaded positioning rods 5, a nested ring 22 fitted into the inner wall of the spring-loaded fixing member 23, and a connecting outer ring 21 fixed inside the nested ring 22. The connecting outer ring 21 is crescent-shaped and its central annular portion has an inward deformation tendency. When the wire harness is embedded in the central annular portion of the connecting outer ring 21, it will press the connecting outer ring 21 to deform inward, so that the connecting outer ring 21 as a whole hugs and locks the optical cable for positioning.

[0019] In an optional embodiment: a plurality of elastic positioning rods 5 are all fitted inside the pull plate 1, and an elastic adjustment assembly 4 is provided on the rear side of the tubular portion of the plurality of elastic positioning rods 5 for driving the tubular portion of the plurality of elastic positioning rods 5 to slide back and forth. The elastic adjustment assembly 4 includes: a spring limiting ring 41, which is slidably fitted to the rear side wall of the pull plate 1 and fixedly connected to the tubular portion of the plurality of elastic positioning rods 5; and an adjustment mechanism, which is provided on the lower side of the spring limiting ring 41 for driving the spring limiting ring 41 to slide linearly inside the pull plate 1. In an optional embodiment: the adjustment mechanism includes a bottom wedge block 42 fixed to the lower side of the spring limiting ring 41, a threaded rod 45 threaded to the bottom of the pull plate 1, a rotating head 44 rotatably connected to the top of the threaded rod 45, and a wedge-shaped pressing block 43 fixed to the top of the rotating head 44. The wedge-shaped pressing block 43 is adapted to the wedge-shaped surface of the bottom wedge block 42. When it is necessary to adjust the adjustment force of the overall device, rotate the threaded rod 45 and use the wedge-shaped pressing block 43 to press the bottom wedge block 42, so that the spring limiting ring 41 slides backward as a whole, so that the spring in the elastic positioning rod 5 is in a certain tension state. At this time, when the cable is released, the cable and the fixed plate 2 need a greater tension force to pull the elastic positioning rod 5 to deform. The bottom of the pull plate 1 is fixedly connected to the fixed clamp 3.

[0020] Working principle: This support device uses the elastic positioning rod 5 to buffer the cable laying process, preventing the positioning structure from locking the optical cable and causing damage to the optical cable due to excessive tension during subsequent laying. During use, the optical cable positioning position is determined, and the pull plate 1 is installed behind this position. The optical cable is then inserted into the slots of the pull plate 1 and the fixed plate 2. During the laying process, if the laying tension is large, the cable will be stretched along with the fixed plate 2 due to friction. When the tension recovers, the elastic positioning rod 5 pulls the optical cable back, ensuring positioning accuracy while effectively preventing damage to the optical cable. When adjusting the overall device's adjustment force, the threaded rod 45 is rotated, and the wedge-shaped pressing block 43 presses against the bottom wedge block 42, causing the spring limiting ring 41 to slide backward. This puts the spring inside the elastic positioning rod 5 in a certain stretched state. At this time, during laying, the cable and fixed plate 2 require greater tension to deform the elastic positioning rod 5.

[0021] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
