It mainly refers to electrical equipment and systems with voltage lower than 220V and current less than 16A.

[0003] During the construction of weak-current engineering, protective pipes are needed to protect the lines that are easily stepped on. For example, Chinese Patent 2022231315436 proposes a protective device for weak-current engineering line pipes. In combination with a plurality of protective convex strips arranged in the protective casing, the line pipes are ultimately wrapped and protected, thereby improving the compressive resistance of the line pipes.

[0004] In the comparative case, during the process of protecting the line, the protective tube is only installed on the outside of the line, which results in the protective tube moving when the workers walk over the top of the protective tube during construction, causing the line to be out of the protection of the protective tube, resulting in the line being stepped on, reducing the service life of the line.

The top and bottom of the interior of the sliding sleeve 41 are connected to a transmission driving arm 42 through a hinge A. The top and bottom of the protective tube 1 are provided with sliding grooves for facilitating the transmission of the driving arm 42. The interior of the sliding groove is slidably connected to the exterior of the driving arm 42.

[0028] See also Figure 3 The end of the driving arm 42 away from the sliding sleeve 41 is connected to a limiting sleeve 43 that can fix the line through a hinge B. The limiting sleeve 43 includes a C-shaped ring. The ends of the two C-shaped rings away from each other are connected to the hinge B. The opposite ends of the two C-shaped rings are fixedly connected with soft pads to prevent the fixed line from causing damage to the line.

[0029] See also Figure 3 The end of the limiting sleeve 43 close to the sliding sleeve 41 is evenly connected with the guide arm of the connecting component, and the outer sliding connection of the guide arm is connected with a sleeve for guiding the limiting sleeve 43 to make it move linearly.

[0030] See also Figure 4 The outside of the protective tube 1 is connected to a protective mechanism 5 for protecting the junction of the threaded sleeve 2 and the threaded cylinder 3. The protective mechanism 5 includes a hollow cylinder 51 of a connecting component. The hollow cylinder 51 is connected to the outside of the protective tube 1.
