DETAILED DESCRIPTION

[0013] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0014] As attached Figure 1-3 As shown, a switch box for temporary power outage during construction site dumping includes a box body 1, a box door 2 and a power connection box 3 are provided on the box body 1, the box door 2 is hinged to the front end of the box body 1 by hinges, and the power connection box 3 is fixed to the rear end of the box body 1 by screws. The four corners of the front end of the power connection box 3 are integrally connected with a docking shaft 4, the front end of the docking shaft 4 is fixed with an electrical installation back plate 5 by screws, and the rear end of the power connection box 3 is fixed with a bottom plate 6 by screws. The bottom plate 6 is provided with a threading tube 7 and a terminal block 8, and the threading tube 7 is fixed to the lower part of the front end surface of the bottom plate 6 by screws, and the threading tube 7 passes through the box body 1 downward and extends to the bottom of the box body 1.

[0015] The terminal block 8 is fixed to the upper front end of the bottom plate 6 by screws. The front end of the terminal block 8 is pre-embedded with a terminal 9. The terminal 9 is symmetrically distributed equidistantly from top to bottom. In this embodiment, six terminal blocks 9 are provided, which are symmetrically distributed from top to bottom. Among them, the terminal blocks 9 on both sides are integrally connected with a power connection sheet 10, and the power connection sheet 10 is provided with a power connection contact 11; the middle terminal blocks 9 are integrally connected with a power supply sheet 12, and the middle of the power supply sheet 12 is connected with an optical axis 13 through a bearing. The optical axis 13 is perpendicular to the power supply sheet 12, and the optical axis 12 can rotate in the bearing. A gravity drop block 15 is welded below the front end of the optical axis 13, and conductive sheets 14 are symmetrically fixed on both sides of the rear end of the optical axis 13 by screws. The conductive sheets 14 are long strips, and the conductive sheets 14 on both sides correspond to the power supply sheets 10 on both sides. The upper and lower ends of the conductive sheets 14 on both sides are respectively fitted with the upper and lower power connection contacts 11 on the corresponding power supply sheets 10.

[0016] Specific usage: the upper terminal 9 is electrically connected to the electrical components on the electrical installation back plate 5 through a wire. When the box 1 is used normally, the conductive sheet 14 can easily connect the upper and lower terminal blocks 9; when the box 1 is tilted or falls, the gravity drop block 15 will tilt with the tilt of the box 1, and the inclination of the gravity drop block 15 drives the optical axis 13 to rotate, and the rotation of the optical axis 13 drives the conductive sheet 14 to rotate and tilt. The conductive sheet 14 tilts and disconnects from the power contact 11. At this time, the upper and lower terminal blocks 9 are disconnected, and the electrical components on the electrical installation back plate 5 are powered off.

[0017] The above is a preferred embodiment of the present invention. For ordinary technicians in this field, according to the teachings of the present invention, without departing from the principles and spirit of the present invention, changes, modifications, substitutions and variations made to the implementation methods are still within the scope of protection of the present invention.
