Description

Technical Field

[0001] The utility model relates to the technical field of endoscope probes, in particular to an endoscope probe with good sealing performance. Background Art

[0002] Industrial endoscopes are widely used, especially in the field of automobile production and maintenance. When using an endoscope to inspect and repair automobiles, the probe will often be inserted into scenes with a lot of oil, such as automobile engines, fuel tanks, and pipelines. When inspecting these places, the oil resistance of the probe is put to the test.

[0003] When the probes of common endoscopes on the market are being inspected, oil accumulates on the surface of the sapphire lens for a long time. The oil will penetrate into the interior through the surrounding gaps, which will greatly reduce the clarity and service life of the camera, thereby increasing the company's maintenance costs. Therefore, it is necessary to develop an endoscope probe with good sealing properties. Utility Model Content
