Electrical beam mounting structure with adjusting function

The invention discloses an electrical beam mounting structure with an adjusting function, which comprises two electrical vertical beams and an electrical cross beam, the electrical cross beam consistsof an upper beam and a lower beam, mounting holes are formed in the front surfaces of the two electrical vertical beams, and a plurality of mounting holes are distributed in a rectangular array in the front surfaces of the two electrical vertical beams. According to the invention, by setting an adjusting and mounting device on the front face of an upper beam, the adjusting and mounting device comprises a first insulating layer; the back surface of the first insulating layer is fixedly bonded with the front surface of the upper beam; therefore, when the electrical cross beam and the first electric appliance element, the second electric appliance element and the third electric appliance element of different sizes are installed, by means of the device, the effects that the stability of the installed electric cross b
