Description

Technical Field

[0001] The utility model relates to the field of photoelectric technology, in particular to a photoelectric frame for a photoelectric sensor. Background Art

[0002] Photoelectric sensors are devices that convert light signals into electrical signals. Their working principle is based on the photoelectric effect. The photoelectric effect refers to the phenomenon that when light shines on certain substances, the electrons of the substance absorb the energy of photons and produce corresponding electrical effects. Photoelectric brackets can be used to install photoelectric sensors.

[0003] The Chinese utility model patent with patent number CN211526011U discloses a photoelectric bracket for a photoelectric sensor of a conveyor. When in use, the movable rod is retracted into the spring groove by pulling the pull pin, and then the movable rod squeezes the spring so that the tooth block no longer engages with the precision fine teeth, and then the adjusting rod is rotated to make the arc sleeve slide on the arc rod. After adjusting the angle of the adjusting rod, the pull pin is released. Under the elastic action of the spring, the tooth block is re-engaged with the precision fine teeth. The angle adjustment accuracy is higher and it is easy to use. By directly sliding the two sliders, the two sliders slide relative to or away from each other on the slide rod, and the sliding distance is the same, the rotating rod starts to rotate to adjust the upper and lower heights of the mounting seat, and then the fixing screw is screwed into the specified threaded hole to fix it. After each adjustment is completed, the mounting seat is in a horizontal state, and the operation is simple.
