[0002] Commonly used distribution boxes are made of wood and metal. Because the metal distribution box has a higher protection level, metal is more commonly used. At the same time, the distribution box can reasonably distribute electrical energy and facilitate the opening and closing of the circuit. The distribution box generally has a higher safety protection level and can intuitively display the conduction status of the circuit.

[0003] A power distribution control device for a power generation system disclosed in the Chinese patent application publication specification CN211266117U includes a control box, and a box cover hinged to the open end of the control box, which can flexibly disassemble and assemble circuit instruments while avoiding the use of fixing parts such as screws, thereby saving maintenance time and improving work efficiency when repairing the entire power generation system.

[0004] Although the above scheme can flexibly disassemble and assemble circuit instruments, the power distribution control box in the above patent is not convenient to fix its position when the box cover is opened. The door of the power distribution cabinet in the above scheme is prone to shaking when it is repaired, affecting the maintenance effect of the power distribution cabinet. For this reason, we provide a flip-top power distribution control box to solve the above problems. Utility Model Content
