Description

Technical Field

[0001] The present invention relates to the technical field of photoelectric sensors, in particular to a photoelectric sensor and an anti-slip functional film. Background Art

[0002] A photoelectric sensor is an instrument that emits visible light or infrared light from a transmitter and detects the light reflected by the object through a receiver to obtain an output electrical signal. Its 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 a corresponding electrical effect occurs. According to the different photoelectric effect phenomena, the photoelectric effect is divided into three categories: external photoelectric effect, internal photoelectric effect and photovoltaic effect. Photoelectric devices include phototubes, photomultiplier tubes, photoresistors, photodiodes, phototransistors, photocells, etc., which are widely used in laboratories. Among them, the through-beam sensor usually includes an independent transmitter and receiver. During normal use, the two independent devices need to be installed in relative positions respectively; the diffuse reflection sensor is a sensor that integrates transmission and reception. The photoelectric sensors commonly used in teaching experiments are mainly composed of a mounting base, a sensor packaging shell, a circuit board, a light path, a light source and a receiver. The sensor is fixed on the experimental table through a mounting base.

[0003] During the experiment, due to the difference in height of the experimental objects, the position height of the photoelectric sensor transmitter and the position facing the receiver need to be adjusted. During the traditional adjustment, it is necessary to tighten the bolts, adjust the installation height of the photoelectric sensor or use the hydraulic rod for telescopic adjustment to adjust the height of the photoelectric sensor. The adjustment operation is not flexible and convenient, which affects the accuracy of the sensor. When the height of the transmitter and the receiver are adjusted separately, there may be a height difference between the two, which makes it impossible for the position height of the photoelectric sensor transmitter and the position facing the receiver to remain.

[0004] To this end, we propose a photoelectric sensor and an anti-slip functional film. Summary of the invention

[0005] In order to make up for the shortcomings of the prior art, the present invention provides the following technical solutions: a photoelectric sensor, comprising a base, a fixing seat fixedly installed on the top of the base, lifting structures are arranged at both ends of the top of the fixing seat, a fixing groove is rotatably arranged inside the lifting structure, a transmitter is fixedly installed inside one of the fixing grooves, a receiver opposite to the transmitter is fixedly installed inside the other fixing groove, the fixing groove is provided with a plug-in groove located at the bottom of the side, a fixing bolt is threadedly connected through the middle of the bottom of the fixing groove, and a stretching rod is plugged into the plug-in groove.

[0009] Preferably, a synchronous wheel located on one side of the first bevel gear is fixedly installed in the middle of the rotating rod, and the two synchronous wheels are connected by a synchronous belt transmission. The diameters of the two synchronous wheels are exactly the same, and the thickness of the synchronous wheel is not greater than the distance between the first bevel gear and the inner wall of the fixed seat.

[0011] Preferably, the two ends of the telescopic sleeve are integrally connected with fixed blocks, and a sliding groove is opened in the middle of the telescopic rod. The fixed block is slidably connected to the inside of the sliding groove. When there is a height difference between the two fixed grooves, the straight-line distance between the two fixed grooves is increased.

The upper convex film and the lower concave film are buckled together. Slip fluorescent powder is arranged between the upper convex film and the lower concave film.

[0016] Beneficial Effects

[0017] Compared with the prior art, the present invention provides a photoelectric sensor having the following beneficial effects:

[0018] 1. This photoelectric sensor is provided with a fixed groove and a stretching rod. Before adjusting the height, the telescopic rods at both ends of the stretching rod are inserted into the plug-in grooves at the bottom of the two fixed grooves, fixed by fixing bolts, and then loosening the tightening screw. The height of the fixed groove is adjusted by the lifting structure. When the heights of the two fixed grooves are different, the two telescopic rods in the stretching rod are automatically extended and retracted, and the stretching rod causes the two fixed grooves to deflect, thereby keeping the transmitter and the receiver facing each other, and then tightening the tightening screw and the tightening cylinder to prevent the receiver and the transmitter from making inaccurate measurements due to height deviations.

[0019] 2. This photoelectric sensor is provided with a lifting structure. When adjusting the height of the fixed groove, the crank is turned to rotate the rotating rod, and at the same time, another rotating rod is driven to rotate synchronously through the synchronous wheel, and then the lifting threaded rod is driven to rotate through the first bevel gear and the second bevel gear, so that the threaded sleeve and the lifting bracket are adjusted in height, thereby driving the fixed groove to be lifted and lowered.

[0020] 3. This photoelectric sensor is provided with a locking hole. When the transmitter or receiver needs to be kept horizontal, the clamping screw is aligned with the locking hole, and the clamping screw is rotated to make the clamping screw and the locking hole plugged, so that the fixing groove is kept horizontal. After the two fixing grooves are kept facing each other and fixed by the clamping screw through the stretching rod, the fixing bolt can be loosened and the stretching rod can be taken out.
