BACKGROUND OF THE INVENTION1. Field of the Invention
The present invention relates to a combined frame, and more particularly to a combined frame for an electromechanical box that can be assembled and positioned easily, can be assembled and carried conveniently to reduce the cost of transportation.
2. Description of Related Art
A conventional frame for an electromechanical box is assembled by multiple beams, multiple columns and multiple corner connectors. After assembling the beams, the columns and the corner connectors of the conventional frame, the beams, the columns and the corner connectors are connected to each other by welding. When the conventional frame is manufactured, the assemblement between the beams, the columns and the corner connectors is difficult and needs to be done in the manufacturing factory. The large space of the conventional frame will increase the costs for transporting the conventional frame.
