Photoelectric output structure based on ANSI standard round table

The utility model discloses a photoelectric output structure based on an ANSI standard round meter, which comprises a transparent meter cover, a base is welded on the inner side surface of a photoelectric output port of the transparent meter cover through ultrasonic waves, a positioning and placing ring is attached to the base, an adsorption metal sheet is arranged in the positioning and placing ring, and the adsorption metal sheet is fixed on the transparent meter cover. A positioning sleeve is arranged outside the adsorption metal sheet, the positioning sleeve is installed on the base in a threaded mode, and a limiting pin used for limiting rotation of the positioning sleeve is embedded and elastically installed on the base. The adsorption metal sheet can be effectively prevented from being rusted, meanwhile, the adsorption metal sheet is detachably installed, installation and later maintenance operation are facilitated, and the adsorption metal sheet has the advantages of being simple in structure and conv
