Technical Field

[0001] The invention relates to the technical field of sensor installation, in particular to a photoelectric sensor which is easy to install. Background Art

[0002] A photoelectric sensor is a sensor that uses the photoelectric effect to convert the measured quantity into an electrical signal for measurement. It is widely used in fields such as automated control, machine vision, and environmental monitoring. It also has important applications in industries such as smart manufacturing, smart homes, and medical health. Photoelectric sensors generally consist of three parts: a light source, an optical path, and a photoelectric element. The core of a photoelectric sensor is a photoelectric element, such as a photodiode (PD) and a light-dependent resistor (LDR).

[0003] In existing photoelectric sensors, it is difficult to allow users to easily adjust the height of the sensor according to actual needs during the installation process. Complex tools or manual adjustments are often required, which fails to improve the convenience and flexibility of installation, reduces the heat dissipation efficiency and operating stability of the photoelectric sensor, increases the frequency and difficulty of manual maintenance, and reduces the service life of the sensor.

The top hinge block 301 is installed on the outside of the support frame 211. The top hinge block 301 is connected to the cleaning plate 303 through the hydraulic rod 302.

A clamping column 405 is slidably connected in the fixing groove 404 at one end of the main body 1, and a spring 406 and a triangular block 407 are installed on the clamping column 405. When the fixing column 401 is inserted into the installation position, the spring 406 pushes the clamping column 405 and the triangular block 407 into the fixing groove 404 to achieve rapid locking, ensuring that the sensor is stable and does not fall off. Multiple groups of components such as the connecting rod 204, the bottom hinge block 208, the slide groove 209, the hinge rod 210, the support frame 211 and the moving groove 212 are all arranged in a circular array.
