Simple polymer cable bridge with L-shaped connecting plates

The utility model relates to a simple polymer cable bridge with an L-shaped connecting plate. The simple polymer cable bridge comprises a bottom plate, a first side plate, a second side plate, the first L-shaped connecting plate, a second L-shaped connecting plate, a first [-shaped connecting plate and a second [-shaped connecting plate, the two sides of the bottom plate are connected with a firstside plate and a second side plate respectively so that the bottom plate can be integrally formed into a U shape, a vertical plate of the first L-shaped connecting plate is connected with the outer side wall of the first side plate, a transverse plate of the first L-shaped connecting plate is connected with one side of the bottom of the bottom plate, and a vertical plate of the second L-shaped connecting plate is connected with the outer side wall of the second side plate. A transverse plate of the second L-shaped connecting plate is connected with the other side of the bottom of the bottom plate; one side of the top
