[0031] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0032] Refer to Figures 1 to 3, the utility model provides an embodiment: a photoelectric detector with an anti-collision structure, including a shell 1, where the shell 1 plays the most basic protective role, and the left side of the shell 1 is fixedly connected with two transmitting ports 2, where the two transmitting ports 2 are the parts of the photoelectric detector that send light. The light emitted by the devices in these ports (such as LEDs or laser diodes) is used for detection, measurement or communication with external devices. The design of the transmitting port 2 must ensure the stability and accuracy of the light, and the right side of the shell 1 is fixedly connected with two receiving ports 3, where the receiving port 3 is responsible for receiving the light reflected from the object or directly transmitted. These ports are usually equipped with photoelectric sensors (such as photodiodes) for detecting changes in optical signals and converting them into electrical signals for subsequent processing. The top of the inner wall of the shell 1 is fixedly connected with a detection device 4, where the detection device 4 is the core measurement and analysis component. It usually includes one or more microprocessors, data processing hardware and firmware software for processing signals received from the receiving port 3.

[0033] The detection device 4 can analyze information such as light intensity, light frequency, and light phase, and then perform tasks such as distance measurement, speed monitoring, and object recognition. The top of the shell 1 is fixedly connected with an indicator light 5, and the indicator light 5 here is used to provide an indication of the operating status of the device. It can display information such as whether the device is powered on, working normally, and in error state, so that the user can quickly understand the operating status of the device. The color and flashing mode of the indicator light 5 usually change according to different states. The bottom end of the shell 1 is detachably connected with a base plate 6, and the base plate 6 here can be removed by screws to facilitate the maintenance and replacement of internal components. The front and rear ends of the shell 1 are fixedly connected with two pillars 7, and the shell 1 here provides stable support for the pillars 7. The front and rear ends of the shell 1 are movably connected with two balls 8, and the outer side of the ball 8 is fixedly connected with an outer column 9. The ball 8 here can ensure that the maximum angle of the outer column 9 is raised when it rotates. The inner wall of the outer column 9 is slidably connected with an inner column 10, and one end of the inner column 10 is fixedly connected with a limit block 11, and the limit block 11 here is used to prevent the inner column 10 from leaving the sliding range of the outer column 9;

[0034] The outer part of the limit block 11 is slidably connected to the inner wall of the outer column 9. One side of the inner wall of the inner column 10 is fixedly connected to a first spring 12, and the other end of the first spring 12 is fixedly connected to one side of the limit block 11. Here, the inner column 10 and the limit block 11 provide stable support for the first spring 12. Two clamping jaws 13 are rotatably connected to the outer side of the support column 7. One end of the inner column 10 is movably connected to the inner side of the clamping jaws 13. When it is necessary to clamp and fix the connected circuit, the circuit can be directly placed outside the two clamping jaws 13, and then the circuit is pressed. At this time, due to the existence of the first spring 12, the inner column 10 slides on the inner wall of the outer column 9, further driving the two clamping jaws 13 to open at a larger angle. After the circuit is clamped, the first spring 12 here will be reset in time because it is subjected to extrusion pressure, so as to ensure the stable clamping of the circuit.

[0035] Refer to Figure 2 、 Figure 4 and Figure 5 , a plurality of support plates 14 are fixedly connected to the bottom end, front end and rear end of the detection device 4. The outer sides of the plurality of support plates 14 are in contact with the top end of the bottom plate 6. Rotating shafts 15 are rotatably connected to both ends of the support plates 14. Here, the plurality of support plates 14 are grouped in fours and are rotatably connected together by four rotating shafts 15 at the same time. Support blocks 16 are fixedly connected to the adjacent sides of two support plates 14. A damper 17 is rotatably connected to the inner side walls of the two support blocks 16. A second spring 18 is sleeved outside the damper 17. The two ends of the second spring 18 are respectively fixedly connected to the two ends of the damper 17. When the outer shell 1 is impacted by the outside or accidentally dropped, the outermost support plate 14 here will be the first to be stressed. At the same time, because it is connected by a plurality of rotating shafts 15, the distance between the upper and lower ends of the plurality of support plates 14 is shortened, thereby stretching the damper 17 and the second spring 18, so that the two generate acting forces at the same time, which cancel out the external impact force, achieving the purpose of protecting the internal detection device 4 and improving the service life of this detector.

[0036] The top of the bottom plate 6 is fixedly connected with a sealing component for ensuring the airtightness of the device, and the sealing component includes a bottom box 19, the bottom end of the bottom box 19 is fixedly connected to the top of the bottom plate 6, and the top end of the bottom box 19 is in contact with the inner wall of the outer shell 1. When the bottom plate 6 is installed to the bottom end of the outer shell 1, the bottom box 19 here will be in close contact with the inner wall of the outer shell 1, and the inner wall of the bottom box 19 is slidably connected with a top plate 20, and the top end of the top plate 20 is in contact with the inner wall of the outer shell 1. The bottom box 19 here provides a stable sliding space for the top plate 20, and the bottom end of the top plate 20 is fixedly connected to a limiting plate 21, and the outer surface of the limiting plate 21 The top plate 20 is slidably connected to the inner wall of the bottom box 19, and the limit plate 21 here can ensure that the top plate 20 will not leave the inner wall range of the bottom box 19. The bottom end of the limit plate 21 is fixedly connected with a spring three 22, and the other end of the spring three 22 is fixedly connected to the bottom end of the inner wall of the bottom box 19. When the bottom plate 6 is installed, the top plate 20 here will first contact the bottom inner wall of the shell 1. As the upward squeezing continues, the spring three 22 here will be gradually compressed, thereby generating an outward pushing force to push the top plate 20 so that it fits tightly with the bottom inner wall of the shell 1, thereby achieving the purpose of improving the sealing of the detector.

[0037] Working principle: During operation, when the photodetector is activated, the transmitting port 2 in the housing 1 emits light, which can be generated by an LED or a laser diode. The light propagates through space and is reflected by the target object or directly received by the receiving port 3. The photoelectric sensor in the receiving port 3 converts the received optical signal into an electrical signal, which is then transmitted to the detection device 4 located at the top of the housing 1. The detection device 4 analyzes and processes these electrical signals, and can determine information such as light intensity, light frequency, and light phase, which is used for tasks such as distance measurement, speed monitoring, and object recognition. At the same time, the operating status of the detection device 4 can be displayed by the indicator light 5 connected to the top of the housing 1. The different colors and flashing modes of the indicator light 5 indicate different working states of the device.

[0038] When the connected line needs to be clamped and fixed, the line can be directly placed on the outside of the two clamping claws 13, and then the line can be pressed. At this time, due to the presence of spring 12, the inner column 10 will slide on the inner wall of the outer column 9, further driving the support column 7 to rotate, so that the two clamping claws 13 open at a larger angle. After the line is clamped, the spring 12 here will be reset in time due to the squeezing force, thereby ensuring the stable clamping of the line. The limit block 11 here ensures that the inner column 10 will not easily leave the sliding range of the outer column 9.

[0039] In addition, when the outer shell 1 is impacted by the outside world or accidentally dropped, the outermost support plate 14 here will be the first to bear the force. At the same time, because it is connected by multiple rotating shafts 15, the distance between the upper and lower ends of the multiple support plates 14 is shortened, thereby stretching the damper 17 and the second spring 18 supported by the support block 16, causing the two to generate acting forces at the same time, which cancel out the impact force from the outside world, achieving the purpose of protecting the internal detection device 4 and improving the service life of this detector.

[0040] When installing the mounting base plate 6, the top plate 20 in the bottom box 19 here will first come into contact with the inner wall of the bottom end of the outer shell 1. As it continues to be squeezed upward, the third spring 22 here will be gradually compressed, thereby generating a force that pushes outward, pushing the top plate 20 to make it fit tightly with the inner wall of the bottom end of the outer shell 1, achieving the purpose of improving the sealing performance of this detector.

[0041] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
