Embedded wiring device for building electrical construction

The invention belongs to the technical field of power supply, and particularly discloses an embedded wiring device for building electrical construction, which comprises a protective shell, trapezoidal plates are fixedly mounted at two ends of the inner side of the protective shell, a reflux plate is jointly mounted between the two trapezoidal plates, and wire clamping assemblies are arranged on the inner walls of two sides, taking the reflux plate as the center, of the two trapezoidal plates. A protection assembly is arranged above the outer side of the protection shell, sleeve shells are clamped in the two sides of the protection shell, air outlet assemblies are arranged on the inner sides of the sleeve shells, inclined tables are fixedly installed on the outer walls of the two sides of the protection shell, and sealing edges are arranged on the edges of the two sides of the two inclined tables. When the device is laid on the ground, a pressing block can be extruded in a wheel walking and pedestrian treading
