[0002] An industrial endoscope is an optical instrument used to perform real-time visual inspection of narrow, curved, or hard-to-access internal spaces without disassembling or damaging the equipment. It consists of a camera, a lighting lamp, a flexible or rigid insertion tube, and a display or control unit, which can transmit internal images to a display screen, computer, or mobile terminal in real time.

[0003] Some existing industrial endoscopes lack scratch-resistant protection structures for their lens assemblies, leaving them exposed. When the industrial endoscope is not in use, the exposed lens assembly may be scratched or squeezed by hard objects, causing the lens to be scratched and affecting its use. In severe cases, the lens may be directly crushed and need to be replaced. Therefore, a scratch-resistant protection structure for industrial endoscopes is proposed to address the above problems.

[0024] A camera 23 is fixedly connected to the end of the mounting housing 22 away from the insertion tube 21. An illumination lamp 24, fixedly connected to the mounting housing 22, is provided on the outside of the camera 23. The endoscope display control unit 1 is electrically connected to both the camera 23 and the illumination lamp 24. The illumination lamp 24 provides illumination, and the camera 23 allows for image capture. A set of circumferentially distributed limiting protrusions 33 are fixedly connected inside the external threaded connector 32. A set of limiting grooves 42 matching the limiting protrusions 33 are provided on the outside of the rubber sleeve 41. The limiting protrusions 33 are all inserted into the limiting grooves 42. The rubber sleeve 41 can be positioned by the limiting protrusions 33 engaging with the limiting grooves 42. The outer side of the rubber sleeve 41 is tightly fitted to the external threaded connector 32, the inner side of the rubber sleeve 41 is tightly fitted to the mounting shell 22, and the inner side of the rubber ring 43 is tightly fitted to the mounting shell 22. The rubber sleeve 41 is clamped by the external threaded connector 32 and the mounting shell 22. The side of the rubber strip 44 near the mounting shell 22 is fitted to the mounting shell 22, the upper end of the rubber ring 43 is aligned with the upper end of the mounting shell 22, and the lower end of the rubber block 45 is fitted to the upper end of the mounting shell 22.

[0025] Workflow: The endoscope display control unit 1 of this device has its own power supply. Before use, the endoscope display control unit 1 should be fully charged. The endoscope display control unit 1 can adjust the operating status of the camera 23 and the illumination lamp 24. All of the above are existing technologies. When using this device, the operator first removes the internal threaded shell 34 from the outside of the external threaded connector 32, then inserts the cannula 21 and the mounting shell 22 into the device that needs to be visualized for inspection. The endoscope display control unit 1 turns on the camera 23 and the illumination lamp 24 and adjusts the brightness of the illumination lamp 24. The 24 can provide illumination, the camera 23 can take pictures, and the captured images can be displayed through the endoscope display control unit 1. After the visual inspection is completed, the staff can reinstall the inner threaded shell 34 onto the outside of the outer threaded connector 32. The inner threaded shell 34 and the mounting base 31 can form a protective space to prevent the camera 23 and the light 24 from being scratched. The rubber sleeve 41, rubber ring 43, rubber strip 44, and rubber block 45 can form a buffer elastic frame structure. When the device is not in use, the buffer frame assembly 4 can stabilize the mounting shell 22, camera 23, and light 24. The buffer frame assembly 4 is positioned within the internal threaded housing 34 and the mounting base 31. If the mounting base 31 and the internal threaded housing 34 are subjected to compression or impact, the buffer frame assembly 4 can provide cushioning, reducing the impact of compression or impact on the mounting housing 22, camera 23, and lighting 24. If compression or impact causes deformation of the mounting base 31 and the internal threaded housing 34, the buffer frame assembly 4 can prevent the mounting base 31 and the internal threaded housing 34 from causing compression or deformation to the mounting housing 22, camera 23, and lighting 24. When using this device, the buffer frame assembly 4 can prevent the parts of the inspected equipment from causing damage to the mounting housing 22. Under pressure or impact, the buffer frame assembly 4 of the device may age after prolonged use. In this case, the rubber sleeve 41 can be pulled out from between the external threaded connector 32 and the mounting shell 22, and the new buffer frame assembly 4 can be installed on the top of the mounting base 31. The rubber sleeve 41 is positioned by the limiting protrusion 33 and the limiting groove 42, and the rubber sleeve 41 is clamped by the external threaded connector 32 and the mounting shell 22, so that the rubber sleeve 41 is stably located between the external threaded connector 32 and the mounting shell 22, and the rubber ring 43, rubber strip 44, and rubber block 45 are stably sleeved on the outside of the mounting shell 22.This device provides enclosed protection for the mounting housing 22, camera 23, and lighting lamp 24 through the mounting base 31 and the internal threaded housing 34. When the mounting base 31 and internal threaded housing 34 are subjected to pressure or impact, the rubber sleeve 41, rubber ring 43, rubber strip 44, and rubber block 45 provide cushioning protection for the mounting housing 22, camera 23, and lighting lamp 24. During use, the rubber sleeve 41, rubber ring 43, rubber strip 44, and rubber block 45 prevent parts of the inspected equipment from causing pressure or impact on the mounting housing 22, camera 23, and lighting lamp 24. This device prevents the camera 23 from being scratched, avoiding situations where the camera 23 cannot capture clear images due to scratches, and effectively improving the service life of the camera 23.
