Description

Technical Field

[0001] The utility model relates to the technical field of cable protection tube covers, in particular to an adjustable secondary cable protection tube cover. Background Art

[0002] Cable casing, also known as protective tube or conduit, is a pipe used to protect wires and cables in electrical installations, allowing wires and cables to be inserted and replaced. Cable casing is a new type of casing material that is widely used in power engineering.

[0003] The existing patent CN208257321U proposes a junction box and a cable protection kit for telescopic connection of cable protection conduits. The utility model realizes the protection of low-voltage outlet cables through conduit threading by adopting two shorter sections of cable protection conduits and the telescopic connection junction box. There is no need to perform precise measurements before threading the conduits. It is only necessary to cut two shorter sections of cable protection conduits of approximate length, which also avoids threading a longer protection conduit at a time, reducing the difficulty of threading the conduits. The grooves of the lower cover and the upper cover of the junction box fit together and snap on both sides of the cable protection conduit, and adjust the position of the cable protection conduit in the first placement portion and the second placement portion, so as to facilitate the alignment of the two sections of cable protection conduits, simplify the process of threading and installing the low-voltage outlet cables, greatly shorten the threading time, and thus reduce the power outage time.

[0004] However, although the existing patent CN208257321U avoids threading a long protective wire tube at a time and reduces the difficulty of threading the tube, the grooves of the lower cover and the upper cover of the wire box are fitted on both sides of the cable protective wire tube, and the positions of the cable protective wire tube in the first placement part and the second placement part are adjusted to facilitate the alignment of the two sections of cable protective wire tubes, which can simplify the process of threading and installing the low-voltage outlet cable, greatly shorten the threading time, and thus reduce the power outage time. However, when a variety of cables of different thicknesses need to pass through the cable protective tube, it may be necessary to adjust the width of different cable troughs.
