Description

Technical Field

[0001] This utility model relates to the field of photoelectric sensor technology, specifically to a photoelectric sensor that is easy to calibrate. Background Technology

[0002] A photoelectric sensor is an instrument that emits visible light or infrared light from a transmitter and obtains an output signal by detecting the light reflected from an object through a receiver. The photoelectric sensor usually relies on a transmitter to emit a light beam, which typically includes a semiconductor light source, a light-emitting diode, an infrared emitting diode, or a laser diode.

[0003] Currently, most photoelectric sensors use an angled cable exit method. The cable is bent at the slot and then electrically connected to the PCB board after passing through the slot. Existing photoelectric sensors, even after ensuring that the cable is bent at a certain angle and connected properly, are not only prone to shaking, but also have insufficient tensile strength, resulting in insufficient stability of the photoelectric sensor during use. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a photoelectric sensor that is easy to calibrate, addressing the shortcomings of the prior art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a photoelectric sensor that is easy to calibrate, including a body, a cable provided on the front side of the body, a tensile mechanism provided on the front side of the body, the tensile mechanism including a fixing plate, a connecting plate, a circular sleeve, a circular rod and a spring, the connecting plate being connected to the top of the fixing plate, the circular rod being connected to the back side of the connecting plate, the circular sleeve being connected to the front side of the body, and the rear end of the circular rod being slidably connected inside the circular sleeve, and the spring being disposed inside the circular sleeve.

[0006] Preferably, the fixing plate has a through hole, and the cable passes through the through hole and is movably connected to the through hole. The two ends of the spring are respectively connected to the rear end of the round rod and the front end of the body.

[0007] Preferably, a limiting rod is connected to the front of the main body, a limiting plate is connected to the outer wall of the fixing plate, the limiting rod passes through the limiting plate and is slidably connected to the limiting plate, and a limiting block is connected to its front end.

[0008] Preferably, the fixing plate is threadedly connected to a lead screw, and the top of the lead screw is rotatably connected to a clamping plate via a bearing.

[0009] Preferably, a limiting groove is formed on the inner wall of the through hole, and a sliding rod is connected to the outer wall of the clamping plate, with one end of the sliding rod slidably connected inside the limiting groove.

[0010] Preferably, the outer wall of the lead screw is connected to a lever, and the lever is located at the bottom of the fixed plate.

[0011] The present invention adopts the above technical solution, which can bring the following beneficial effects:

[0012] 1. This easily calibrated photoelectric sensor, by passing the cable through a through hole and loosening the cable portion on the back of the fixing plate before fixing the cable to the fixing plate, allows the spring to extend and buffer when subjected to external force, thereby improving the tensile strength of the cable and enhancing the stability of the photoelectric sensor in use.

[0013] 2. This easy-to-calibrate photoelectric sensor uses a lever to rotate a lead screw, which in turn drives a clamping plate to clamp and fix the cable passing through the through hole, thus facilitating cable positioning. Rotating the lever in the opposite direction releases the clamping plate, making operation simple and convenient. Attached Figure Description

[0023] Specifically, by passing the cable 2 through the through hole and loosening the cable 2 on the back of the fixing plate 31, the cable 2 is then fixed to the fixing plate 31.
