Description

Technical Field

[0001] The utility model belongs to the technical field of proximity sensors, in particular to a safety proximity sensor. Background Art

[0002] Safety proximity sensors are key safety devices in industrial automation. They use non-contact detection technology, such as photoelectric, ultrasonic or electromagnetic induction principles, to accurately monitor the position or existence of objects. They can achieve high-sensitivity detection without direct contact with the object being measured, ensuring the safety and efficiency of production lines or machines during operation. They are widely used in mechanical safety protection, automated production lines, logistics and transportation, etc., effectively preventing safety hazards such as collisions and misoperations, and improving the stability and safety of the overall working environment.

[0003] A Chinese patent with publication number "CN213633873U" discloses an annular proximity sensor, comprising a base, a base surface of the base being vertically fixedly connected to a vertical pole, a clamping mechanism being movably installed on the vertical pole, and a material receiving mechanism being fixedly connected to the side wall near the top; the clamping mechanism comprises a lifting square tube, a locking bolt being threadedly connected to the side wall of the lifting square tube, and an L-shaped plate being fixedly connected to the side wall, a guide strip being fixedly connected to the inner side of the L-shaped plate, a clamping plate being slidably connected to the outer wall of the guide strip, a driving screw being threadedly connected to the clamping plate, and an annular proximity sensor being clamped between the L-shaped plate and the clamping plate.

[0004] However, this device still has some shortcomings. Since the position and angle of the base are fixed, the angle of the vertical pole cannot be adjusted after the base is installed, which is not conducive to the user's later adjustment of the angle of the annular proximity sensor. At the same time, since the vertical pole is a whole, the height of the vertical pole cannot be adjusted, so the height adjustment of the annular sensor body can only be limited to the height of the vertical pole, which is not conducive to the user's later disassembly and maintenance of the structure on the device.
