Description

[Technical Field]

[0001] The present invention relates to the technical field of cable concentrators, and more particularly to a cable concentrator that allows easy replacement of pull cables. [Background technology]

[0002] 1 shows a conventional line concentrator 1. The line concentrator 1 comprises a metal support 11, a winding wheel 12, and a spring tube 13. The metal support 11 has a shaft 111, a lift handle 112 connected to one end of the shaft 111, and a base 113 connected to the other end of the shaft 111. The base 113 comprises two base frames 114 and a fixed part 115. The two base frames 114 are erected at both ends of the shaft 111, respectively, and the fixed part 115 is fixed to the end of the shaft 111 that is not connected to the lift handle 112. However, when the two base frames 114 are connected to the shaft 111 using the fixed part 115, an internal space 116 is formed, and a guide rod 117 is connected above the fixed part 115. The take-up wheel 12 is axially mounted in the internal space 116 and includes an integral wheel frame 121 and a sleeve 122 connected to one side of the wheel frame 121. The wheel frame 121 has a wire winding area 1211 corresponding to the pull cable 14. One end of the pull cable 14 is fixed within the wheel frame 121, and the sleeve 122 is fitted onto the shaft 111, allowing the take-up wheel 12 to rotate freely. One end 131 of the spring tube 13 passes through one end of the guide rod 117 and is fixed thereto. The pull cable 14 in the take-up wheel 12 passes through one end 131 of the spring tube 13 and is fed or retracted from the other end 132.

[0003] At a construction site, because the ring frame 121 is one piece, it cannot be quickly removed to replace a pull cable 14 of a different type or length; to do so, it is necessary to first pull out all of the pull cables 14 inside the ring frame 121 and then pull the desired pull cable 14 back into the ring frame 121, making replacement difficult and inconvenient. For this reason, operators prepare multiple concentrators 1 that are compatible with pull cables 14 of different specifications, types, and lengths to shorten the time it takes to replace pull cables 14, but the metal support 11 of each concentrator 1 is large and quite heavy, making it inconvenient to carry. <Prior art documents> <Patent Document 1> International Publication No. 2013 / 122682 Summary of the Invention [Problem to be solved by the invention]
