[0002] In building construction, pre-embedded cabling devices are crucial facilities for ensuring the normal operation of subsequent electrical and communication systems. Their function is to pre-lay pipelines during construction stages such as concrete pouring, providing a channel for later cable laying. An existing technical specification (CN221080862U) describes a cable pre-embedded cabling device, including a junction box. The device is characterized by cable holes extending through both sides of the junction box. A clamping spring is fixedly connected to the inner surface of each cable hole, and a telescopic rod is fixedly connected to the inner surface of each cable hole. A clamping plate is fixedly connected to one end of the telescopic rod. A lower clamping block is movably connected to the inner cavity of the junction box. A limiting groove is provided on one side of the lower clamping block, and a movable plate is movably connected to the inner cavity of the limiting groove. A toggle block is fixedly connected to the top surface of the movable plate, and a limiting spring is fixedly connected to one side of the movable plate. This design better ensures that the cable does not wear against the cable holes when pulled, protecting the cable. However, this common pre-embedded cabling device still has shortcomings: Each cable has its own hole, which requires multiple connecting conduits when connecting to the junction box and wiring conduit. This increases costs and construction difficulty. In addition, the lack of a plug makes it easy for concrete to be poured into the junction box when sealing it with tape later. Utility Model Content

[0003] The purpose of this utility model is to provide a pre-embedded wiring device for construction sites, which solves the problem mentioned in the background art that each cable needs to be set with a separate wire hole, and multiple connecting conduits are required when connecting the junction box and the wiring conduit, which is costly and increases the difficulty of construction. At the same time, the lack of a plug makes it easy for concrete to be poured into the junction box when sealing it with tape later.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a pre-embedded wiring device for construction sites, comprising a wiring box, with wiring conduits at both ends of the wiring box, wiring openings at the connection points of the two wiring conduits and the wiring box, rounded corners inside the two wiring openings, branching components fixedly connected to both sides inside the wiring box, multiple limiting mechanisms provided in the middle of the inner wall of the wiring box, and an intercepting cover mechanism provided on one side of the wiring box.
