Industrial endoscope is a new non-destructive flaw detector that integrates optics, precision machinery, electronic technology and microscopic camera technology. It is widely used. Non-destructive inspection can be realized without disassembly, destruction of assembly and stop operation of equipment during inspection of equipment. The industrial endoscope can accurately check the faults of the equipment. The endoscope probe can accurately control the steering, explore the depths of the curved pipeline, observe the parts that cannot be directly viewed, and observe the internal space in the sealed cavity Structure and state, extend the visual distance, can realize long-distance observation and operation, multi-directional inspection, and accurately observe the real situation inside the object, comprehensively check the corrosion, rust spots, cracks, scratches, bumps and other problems inside the equipment to reduce work intensity and improve work efficiency. This industrial endoscope design is a series of innovative designs carried out by designers from appearance design, structural design and hand board. The color is matched with black and red, and the appearance design is streamlined, with intuitive and simple shape. The design conforms to ergonomics, pays attention to details, the handheld size is small and light, convenient to carry, strong applicability, simple operation, and very safe to use. The industrial endoscope adopts precision mold injection molding to improve the durability of the product in harsh environments; the surface of the rotating button has stripes to increase friction and is easy to operate; the gradual change round hole design makes the device have a better grip and improves the operation comfort; The pipe diameter is compact, portable and convenient, and flexible to move; equipped with a high-definition camera, the image quality is clear, and it has the functions of taking pictures and recording, it can clearly and accurately reflect the static image and dynamic video of the measured object; the data can be stored and imported into the computer to form a test report; the precise probe design, the inserted tube probe is waterproof, oil-resistant, and anti-corrosion, and the detection is more accurate and efficient. Strong environmental adaptability. Industrial endoscopes are widely used, and are currently mainly used for automobile maintenance, aero-engine inspection, pipeline inspection, mechanical parts inspection, etc.
