Distribution box for building power distribution

Abstract

The invention discloses a distribution box for building power distribution. The distribution box comprises a box body, inspection windows, a box door, pillar feet and a wire inlet and outlet. The box body is hinged with the box door thereon. The box door is provided with a lock thereon. Two or more inspection windows are arranged on the box door on the left side of the box body. The box body is fixed by the pillar feet at the bottom. The box body is provided with wire inlet and outlet at the bottom end thereof. A primary rubber thread loop cooperates with an intake pipe, an induction stroke switch and a secondary rubber thread loop. When the primary rubber thread loop has a crack due to the friction of a hard object, the sealing property is destroyed. The airflow is induced by the induction stroke switch when the airflow enters the intake pipe through the crack. The induction stroke switch automatically starts a motor. Guide wheels and a driving belt, on which the motor acts, drive sliding bodies. The sliding bodies and the secondary rubber thread loop fixed thereby move upward, and the damaged primary rubber thread loop is wrapped and sealed by a protective groove, so that the sealing and insulation properties of equipment can be effectively maintained.

Description

technical field [0001] The invention relates to the field of power distribution, in particular to a power distribution box for building power distribution. Background technique [0002] The building distribution box is an important part used for power distribution and transmission in the construction equipment engineering. It is an indispensable construction and installation project in the building. The bottom of the box, the inlet and outlet holes must be insulated and protected with rubber wire rings, because the rubber wire rings are made of silicone rubber and the texture is relatively soft. In some construction sites, the environment is relatively harsh, and some distribution boxes installed at low places have The rubber wire ring is very easy to be rubbed by hard objects and cracks will appear, which will damage the sealing performance.
