[0002] A slotted photoelectric switch is a photoelectric sensor typically installed on automated machinery to sense the position of objects. Currently, the sensor mounting location usually has two slots, and the sensor is connected to the slots via bolts. Depending on the equipment's requirements, the sensor can be installed in different positions on the slots. When the sensor needs to be replaced or maintained, it must be removed from the mounting slot and reinstalled. Since the sensor needs to be installed in the same position as before removal, it is necessary to reposition the sensor during removal. Currently, sensor positioning is done by drawing lines next to the mounting slot, but this method has low positioning accuracy, and multiple adjustments are required after sensor installation before the equipment can operate normally in production.

[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0024] Reference Figures 1 to 3As shown, a sensor mounting positioning mechanism of the present invention includes: a first positioning arm 1, the first positioning arm 1 including a first positioning part 14; a second positioning arm 2, the second positioning arm 2 being hinged to the first positioning arm 1, an elastic member 3 being provided between the second positioning arm 2 and the first positioning arm 1, the second positioning arm 2 including a second positioning part 24, the first positioning part 14 extending away from the second positioning arm 2, the second positioning part 24 extending away from the first positioning arm 1, and the distance between the first positioning part 14 and the second positioning part 24 gradually increasing away from the elastic member 3.

[0025] This embodiment of a sensor mounting positioning mechanism applies pressure to the first positioning arm 1 and the second positioning arm 2, causing them to rotate relative to each other. Simultaneously, the elastic element 3 is compressed, reducing the distance between the first positioning part 14 and the second positioning part 24. The first positioning part 14 and the second positioning part 24 can then enter the two mounting slots 41 respectively, with one side of each part abutting against the end of the sensor 5 to be removed. Then, the pressure applied to the first positioning arm 1 and the second positioning arm 2 is stopped. At this point, the elastic element 3 causes the first positioning part 14 and the second positioning part 24 to abut against the side walls of the two positioning slots respectively, and the sensor mounting positioning mechanism is fixed in position. The sensor 5 to be removed is then disassembled. After disassembly, the end of the sensor to be installed is abutted against the same side of the first positioning part 14 and the second positioning part 24. Finally, the sensor to be installed is connected to the mounting slot 41, thereby completing the sensor replacement. By hinged to the first positioning arm 1 and the second positioning arm 2, the first positioning part 14 and the second positioning part 24 can extend into the mounting groove 41. By setting the elastic element 3 between the first positioning arm 1 and the second positioning arm 2, the first positioning part 14 and the second positioning part 24 can abut against the side wall of the mounting groove 41, thereby fixing the position of the sensor mounting positioning mechanism. By abutting against the sensor, the first positioning part 14 and the second positioning part 24 can quickly position the sensor with high positioning accuracy, thus improving the installation accuracy of the sensor.

[0026] The first positioning arm 1 and the second positioning arm 2 are hinged, allowing them to rotate relative to each other. An elastic element 3 is provided between the second positioning arm 2 and the first positioning arm 1 to reset the first positioning arm 1 and the second positioning arm 2. The first positioning arm 1 includes a first positioning part 14, and the second positioning arm 2 includes a second positioning part 24. The first positioning part 14 extends away from the second positioning arm 2, and the second positioning part 24 extends away from the first positioning arm 1. The distance between the first positioning part 14 and the second positioning part 24 gradually increases away from the elastic element 3, causing the ends of the first positioning part 14 and the second positioning part 24 to protrude away from each other, thereby making the contact between the first positioning part 14 and the second positioning part 24 and the mounting groove 41 more stable.

[0027] Reference Figures 2 to 4 As shown, specifically, the first positioning arm 1 includes a first connecting plate 11 and a second connecting plate 15 located at the end of the first connecting plate 11, and the second positioning arm 2 includes a third connecting plate 21 and a fourth connecting plate 25 located at the end of the third connecting plate 21. That is, the end of the second connecting plate 15 is connected to the end of the first connecting plate 11, the end of the third connecting plate 21 is connected to the end of the fourth connecting plate 25, and the angle between the first connecting plate 11 and the second connecting plate 15 is an obtuse angle, and the angle between the third connecting plate 21 and the fourth connecting plate 25 is an obtuse angle.

[0028] The third connecting plate 21 is hinged to the fourth connecting plate 25. Specifically, the sensor mounting positioning mechanism also includes a connecting shaft. The second connecting plate 15 has an opening 16 and a first mounting hole 17 that penetrates the opening 16. The width of the fourth connecting plate 25 matches the width of the opening 16. The fourth connecting plate 25 penetrates the opening 16 and has a second mounting hole 26 corresponding to the first mounting hole 17. The connecting shaft penetrates the first mounting hole 17, the second mounting hole 26, and the opening 16. That is, the connecting shaft penetrates the second connecting plate 15 and the fourth connecting plate 25. The second connecting plate 15 and the fourth connecting plate 25 are rotatably connected to the connecting shaft, thereby making the first positioning arm 1 and the second positioning arm 2 hinged.

[0029] The elastic element 3 can be considered as a spring. It is located between the first connecting plate 11 and the second connecting plate 15. A first slot 12 is provided on the side of the first positioning arm 1 near the second positioning arm 2, and a second slot 22 is provided on the side of the second positioning arm 2 near the first positioning arm 1. Both ends of the elastic element 3 are located within the first slot 12 and the second slot 22, respectively. Specifically, the first slot 12 is located on the side of the first connecting plate 11 near the second connecting plate 15, and the second slot 22 is located on the side of the second connecting plate 15 near the first connecting plate 11, thus making the first slot 12 and the second slot 22 opposite to each other. Both ends of the elastic element 3 are located within the first slot 12 and the second slot 22, respectively, and are connected to the first slot 12 and the second slot 22, thereby fixing the elastic element 3.

[0030] Both the first positioning part 14 and the second positioning part 24 are plate-shaped. The first positioning part 14 is located at the end of the first connecting plate 11 away from the second connecting plate 15, and the second positioning part 24 is located at the end of the third connecting plate 21 away from the fourth connecting plate 25. Specifically, the end of the first connecting plate 11 away from the second connecting plate 15 is provided with a first protrusion 13, and the first positioning part 14 is connected to the first protrusion 13. The angle between the plane of the first positioning part 14 and the plane of the first connecting plate 11 is an obtuse angle. The end of the third connecting plate 21 away from the fourth connecting plate 25 is provided with a second protrusion 13. The second positioning part 24 is connected to the second protrusion 23. The plane where the second positioning part 24 is located makes an obtuse angle with the plane where the third connecting plate 21 is located. At the same time, the first positioning part 14 extends in the opposite direction to the second connecting plate 15, and the second positioning part 24 extends in the opposite direction to the fourth connecting plate 25. This causes the first positioning part 14 to extend away from the second positioning arm 2, and the second positioning part 24 to extend away from the first positioning arm 1. The distance between the first positioning part 14 and the second positioning part 24 gradually increases in the direction away from the elastic member 3.

[0031] Preferably, the thickness of the first positioning part 14 and the second positioning part 24 gradually decreases in the direction away from the elastic member 3, that is, the first positioning part 14 and the second positioning part 24 are wedge-shaped as a whole, so that the first positioning part 14 and the second positioning part 24 are more stable when they abut against the side wall of the mounting groove 41 of different widths.

[0032] Reference Figure 5As shown, this utility model also provides a sensor mounting connection device, including the aforementioned sensor mounting positioning mechanism and a mounting base 4. The mounting base 4 includes at least two mounting slots 41. In this embodiment, the mounting base 4 has two mounting slots 41. Through the relative rotation of the first positioning arm 1 and the second positioning arm 2, the first positioning part 14 and the second positioning part 24 can respectively enter the two mounting slots 41. After the pressure applied to the first positioning arm 1 and the second positioning arm 2 is stopped, the elastic member 3 drives the first positioning part 14 and the second positioning part 24 to move in a direction away from each other, so that the first positioning part 14 and the second positioning part 24 abut against the two sides of the two mounting slots 41 furthest apart, thereby fixing the sensor mounting positioning mechanism relative to the mounting base 4. The sensor 5 to be disassembled is connected to the mounting slot 41, and the sensor 5 to be disassembled is positioned by the abutment of the first positioning part 14 and the second positioning part 24 against the sensor 5 to be disassembled.

[0033] In use, pressure is applied to the first positioning arm 1 and the second positioning arm 2, causing them to rotate relative to each other. Simultaneously, the elastic element 3 is compressed, reducing the distance between the first positioning part 14 and the second positioning part 24. The first positioning part 14 and the second positioning part 24 can then enter the two mounting slots 41 respectively, with one side of each part abutting against the end of the sensor 5 to be removed. Then, pressure is stopped on the first positioning arm 1 and the second positioning arm 2. At this point, the elastic element 3 drives the first positioning part 14 and the second positioning part 24 to move away from each other, so that the first positioning part 14 and the second positioning part 24 abut against the two sides of the mounting slots 41 furthest apart. At the same time, the sensor mounting positioning mechanism is fixed relative to the mounting base 4. Then, the sensor 5 to be removed is disassembled. After disassembly, the end of the sensor to be installed is abutted against the same side of the first positioning part 14 and the second positioning part 24. Finally, the sensor to be installed is connected to the mounting slot 41, thus completing the sensor replacement.

[0034] This utility model discloses a sensor mounting positioning mechanism and connecting device. Through the hinge of a first positioning arm 1 and a second positioning arm 2, the first positioning part 14 and the second positioning part 24 can extend into the mounting groove 41. The elastic element 3 between the first positioning arm 1 and the second positioning arm 2 allows the first positioning part 14 and the second positioning part 24 to abut against the side wall of the mounting groove 41, thereby fixing the position of the sensor mounting positioning mechanism. The abutment between the first positioning part 14 and the second positioning part 24 and the sensor enables rapid and accurate sensor positioning, improving the sensor mounting accuracy. The distance between the first positioning part 14 and the second positioning part 24 gradually increases away from the elastic element 3, causing the ends of the first positioning part 14 and the second positioning part 24 to protrude away from each other, thus making the abutment between the first positioning part 14 and the second positioning part 24 and the mounting groove 41 more stable.

[0035] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
