Description

Technical Field

[0001] This utility model relates to the field of photoelectric switch technology, specifically a photoelectric switch with protective function. Background Technology

[0002] Photoelectric switches with protective functions are photoelectric switches with additional protective features to enhance their reliability and durability in harsh environments or special application conditions.

[0003] A search revealed a Chinese utility model patent, CN214851180U, which discloses an electrical switch comprising: a U-shaped housing, a U-shaped circuit board located within the U-shaped housing, two lenses, a patch photoelectric transmitter, and a patch photoelectric receiver. The U-shaped housing includes two opposing housing arms and a connecting shell located between and connecting the two housing arms; each housing arm has a slot. The U-shaped circuit board includes two opposing plate arms and a connecting plate located between and connecting the two plate arms; each plate arm is located within one of the two housing arms. The two lenses are fixed to the wall of one of the two slots. The patch photoelectric transmitter and patch photoelectric receiver are respectively fixed on the plate arm within one of the two housing arms and are respectively facing one of the two slots. The photoelectric switch provided by this utility model embodiment simplifies the installation process when installing a photoelectric switch.

[0004] However, this device often lacks quick connection and device angle adjustment functions. It is not easy to quickly disassemble the photoelectric switch body during use, nor is it easy to adjust the angle of the photoelectric switch body according to the needs of the usage scenario, which reduces convenience and flexibility. Moreover, the device also lacks cleaning function, making it inconvenient to wipe the sensor surface of the photoelectric switch body during use, which may affect the normal operation of the photoelectric switch body. Utility Model Content

[0005] The purpose of this invention is to provide a photoelectric switch with protective function to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A photoelectric switch with protective function includes a connecting piece. A groove is formed on the top of the connecting piece, and a mounting assembly is slidably connected inside the groove. The mounting assembly includes a sliding rod, the surface of which is slidably connected to the inside of the groove. A connecting block is fixedly connected to one end of the mounting assembly, and a fixing groove is formed at one end of the connecting block. A servo motor (A servo motor) is fixedly connected inside the fixing groove. An A transmission rod is splinedly connected to the output end of the servo motor. A protective shell is fixedly connected to one end of the transmission rod. A photoelectric switch body is fixedly connected inside the protective shell. Cleaning components are provided on opposite inner sides of the photoelectric switch body. Each cleaning component includes a cleaning frame, one end of which is fixedly connected to one end inside the photoelectric switch body.

[0008] Preferably, one end of the connecting piece is provided with four sets of threaded holes, and each of the four sets of threaded holes is threaded with a connecting screw.

[0009] Preferably, the installation assembly further includes a convenient block, the center of the bottom surface of which is fixedly connected to the top of the slide rod, and springs are fixedly connected to both sides of the bottom surface of the convenient block.

[0010] Preferably, the bottoms of both sets of springs abut against the middle of the top surface of the connecting piece, the bottom of the slide rod is fixedly connected to block A, block B is slidably connected to the surface of block A, and one end of block B is fixedly connected to the end of the connecting block away from the fixing groove.

[0011] Preferably, the cleaning assembly further includes a motor housing, one side of which is fixedly connected to one side of the cleaning frame. A B servo motor is fixedly connected inside the motor housing, and a B transmission rod is splinedly connected to the output end of the B servo motor. A threaded rod is fixedly connected to one side of the B transmission rod. The cleaning frame has movable grooves at its inner top and bottom. A cleaning block is threadedly connected to the surface of the threaded rod, and the top and bottom of the cleaning block are slidably connected to the inside of the movable groove.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. By installing the components, A servo motor, and A transmission rod, during use, the operator first connects the connecting piece to the external device using four sets of connecting screws. Then, the convenient block is lifted upwards, causing the slide rod, spring, and A-block to move upwards. The B-block is aligned with the groove on the surface of the connecting piece and inserted. When the B-block moves to a certain position, the convenient block is released, and the spring causes the A-block, slide rod, and convenient block to spring back, so that the surface of the A-block is locked on the top of the B-block. Then, through the action of the A servo motor and A transmission rod, the external power supply is connected, and the A servo motor is started. The A servo motor drives the A transmission rod and the protective shell to rotate, so that the angle of the photoelectric switch body can be adjusted, thereby improving the convenience and flexibility of the photoelectric switch device.

[0014] 2. With the cleaning component set up, when in use, first connect the external power supply and start the B servo motor. The B servo motor drives the B transmission rod and the threaded rod to rotate. The rotation of the threaded rod causes the cleaning block to move back and forth inside the cleaning frame, cleaning the sensor surface inside the photoelectric switch body. This prevents dust and other impurities from adhering to the sensor surface, which would affect the normal use of the photoelectric switch body. This ensures the cleanliness of the sensor surface and guarantees the normal operation of the photoelectric switch body. Attached Figure Description

Cleaning components 9 are provided on the opposite inner sides of the photoelectric switch body 8. The cleaning components 9 include a cleaning frame 901. One end of the cleaning frame 901 is fixedly connected to one end inside the photoelectric switch body 8.

[0023] In this embodiment, preferably, one end of the connecting piece 1 is provided with four sets of threaded holes, and each of the four sets of threaded holes is threaded with a connecting screw 10. The setting of the connecting screw 10 facilitates connection with external equipment.

[0024] In this embodiment, preferably, the mounting component 3 further includes a convenient block 302. The center of the bottom surface of the convenient block 302 is fixedly connected to the top of the slide bar 301. Springs 303 are fixedly connected to both sides of the bottom surface of the convenient block 302. The springs 303 facilitate the rebound of the convenient block 302 and the slide bar 301.

[0025] In this embodiment, preferably, the bottoms of both sets of springs 303 abut against the middle of the top surface of the connecting piece 1, and the bottom of the slide rod 301 is fixedly connected to a locking block 304. A locking block 305 is slidably connected to the surface of the locking block 304. One end of the locking block 305 is fixedly connected to the other end of the connecting block 4. The setting of the locking block 304 and the locking block 305 facilitates the quick installation and disassembly of the photoelectric switch body 8 and external devices.

[0026] In this embodiment, preferably, the cleaning component 9 further includes a motor housing, one side of which is fixedly connected to one side of the cleaning frame 901. A B servo motor 902 is fixedly connected inside the motor housing. The output end of the B servo motor 902 is splinedly connected to a B transmission rod 903. A threaded rod 904 is fixedly connected to one side of the B transmission rod 903. The B servo motor 902 facilitates the rotation of the B transmission rod 903 and the threaded rod 904.
