Description

Technical Field

[0001] The utility model belongs to the technical field of optical cable surplus cable placement technology, and more specifically, particularly relates to a foldable surplus cable rack which is convenient for fixing the inner reel of an OPGW optical cable. Background Art

[0002] In the communication optical cable overhead line, in order to ensure the subsequent maintenance and re-splicing of the optical cables at the frame in the substation, some OPGW spare cables and ordinary optical cables need to be reserved at the optical cable joints. In order to ensure that the OPGW optical cables and ordinary optical cables reserved at the frame are fixed intact in the circular spare cable rack, an insulated inner-bend spare cable rack device is often used.

[0003] Based on the above, the inventors have found the following problems: the existing excess cable rack device also has the following shortcomings: 1. The optical cable excess cable rack occupies a large space when not in use, which is inconvenient to carry; 2. The optical cable is easy to loosen after being collected and is not easy to store; 3. The tail cables of the excess cable rack include OPGW optical cable and ordinary cable. The OPGW optical cable has outward tension when it is coiled, and the ordinary cable is relatively loose when it is coiled, and there is a downward hammering phenomenon. The adaptability of the existing excess cable rack to this phenomenon needs to be improved.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a foldable excess cable rack is provided to facilitate the fixation of the inner reel of the OPGW optical cable, in order to achieve a more practical purpose. Utility Model Content

[0005] The purpose and function of the foldable excess cable rack for facilitating the fixing of the inner reel of the OPGW optical cable of the utility model are achieved by the following specific technical means:

[0006] A foldable excess cable rack for fixing an inner reel of an OPGW optical cable comprises a bracket one, a bracket two and bolts, wherein the bracket one is a hollow bracket, the bracket two is a solid bracket, the shape and size of the bracket two are the same as the shape and size of the cavity inside the bracket one, the bracket two penetrates the bracket one, and the central intersection of the two is assembled and installed by bolts, through-hole grooves are penetrated around the bolts at the top of the bracket one, and a clamping assembly is provided on the top of the bracket two.

[0007] Furthermore, the engaging assembly includes a chamber opened at the top of the second bracket, the inner wall of the chamber is provided with a limiting groove, a protruding block is slidably provided between the limiting grooves, and a spring is installed in the chamber below the protruding block.

[0008] Furthermore, the tops of the bracket one and the bracket two are penetrated with mounting holes, and latch columns are inserted and installed in the mounting holes.

[0009] Furthermore, the number of the through hole slots is four, and the number of the engaging components is two.

[0010] Furthermore, the bracket one and the bracket two are made of metal material, and the surfaces of the bracket one and the bracket two are provided with a galvanized layer.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] 1. By setting the clamping assembly, using the nuts and studs on both sides of the center of the frame, and using tools to drive the bolts to rotate, the two frames can be adjusted to the corresponding angles according to the actual situation on site, which is convenient for disassembly and transportation, and makes the cable rack adapt to the installation and fixing platform under different conditions. It is suitable for the winding of surplus communication optical cables and can be used with the existing cable rack.

[0013] 2. By setting up an inner L-shaped baffle assembly, the elastic characteristics of the inner L-shaped baffle when the OPGW inner disk is fixed are utilized to facilitate the adjustment of the cable coiling radius. Secondly, the baffle can support the external elastic force of the OPGW optical cable when the bending angle is large when the optical cable is coiled, avoiding the danger of the OPGW remaining cable rebounding to the external live part.

[0014] 3. By setting the latch column, three holes at far, middle and near positions are set on both sides of the plate frame, so that the support column can choose the rotating and fastening position according to the actual situation of the residual cable. Firstly, it can provide upward supporting force for the common cable residual cable, and has good adaptability when the residual cables of two characteristics are coiled in the residual cable frame. Secondly, it can adapt to the conditions of different residual cable lengths. Finally, it is easy to disassemble during maintenance, which will not affect the construction difficulty and maintenance efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] Example:

[0025] As attached Figure 1 To Attachment Figure 4 As shown:

[0026] The utility model provides a foldable excess cable rack for fixing the inner reel of an OPGW optical cable, comprising a bracket 1, a bracket 2 and a bolt 5, wherein the bracket 1 is a hollow frame, the bracket 2 is a solid frame, the shape and size of the bracket 2 are the same as the shape and size of the cavity inside the bracket 1, the bracket 2 passes through the bracket 1, and the central intersection of the two is assembled and installed by the bolt 5, the bolt 5 is surrounded by a through hole groove 8 located at the top of the bracket 1, and the top of the bracket 2 is provided with a clamping assembly, and the design of the clamping assembly can realize that the bracket 2 is stored in the bracket 1, so that the excess cable rack as a whole is convenient for carrying in a storage box.

[0027] Among them, the locking assembly includes a chamber opened on the top of the bracket 2, the inner wall of the chamber is provided with a limit groove, a protruding block 7 is slidably provided between the limit grooves, and a spring 6 is installed in the chamber below the protruding block 7. The protruding block 7, the spring 6 and the through hole groove 8 are used together. When the protruding block 7 is pressed, the bracket 2 can be rotated so that the bracket 2 and the bracket 1 are 90 degrees, and then the protruding block 7 is released. At this time, the protruding block 7 is again engaged in the through hole groove 8 by the reaction force of the spring 6. Through the above operation, the remaining cable rack can be opened as a whole and effectively fixed, which is convenient for the subsequent winding and storage of the cables and improves its convenience.

[0028] The tops of the bracket 1 and the bracket 2 2 are both penetrated with mounting holes 3 , and the mounting holes 3 are inserted with latch posts 4 .

[0029] There are four through-hole slots 8 and two engaging components.

[0030] Among them, the bracket 1 and the bracket 2 2 are made of metal material, and the surfaces of the bracket 1 and the bracket 2 2 are provided with a galvanized layer. Through the design of the galvanized layer, the overall oxidation resistance and corrosion resistance can be increased, so that the overall service life of the cable rack is extended.

[0031] The specific usage and function of this embodiment are as follows:

[0032] Before using this type of cable rack, first determine the overall integrity of the cable rack, confirm that the cable rack is correctly installed in the designated position, then press the protruding block 7 downward, and push the bracket 2 2 to rotate 90 degrees. When the bracket 1 and the bracket 2 are 90 degrees, the protruding block 7 is subjected to the reaction force of the spring 6, forcing the protruding block 7 to snap into the through hole groove 8 again, thereby completing the overall opening of the cable rack, otherwise the cable rack is closed. Through the above operation, the cable rack can be quickly opened and closed, which is convenient for later carrying and processing. In order to reel the corresponding cables between the bracket 1 and the bracket 2, a latch column is set, and holes at three positions of far, middle and near are set on both sides of the plate frame, so that the support column can select the rotation and fastening position according to the actual situation of the cable. First, it can provide upward support for the ordinary cable cable, and has good adaptability when the cable with two characteristics is coiled in the cable rack. Secondly, it can adapt to the situation of different cable lengths. Finally, it is also easy to disassemble during maintenance, which will not affect the construction difficulty and maintenance efficiency.
