Description

Technical Field

[0001] The utility model relates to the technical field of endoscope detection, in particular to a connecting rod with a telescopic and rotatable lens and an endoscope. Background Art

[0002] As the transmission wires of endoscopes on the market are not strong enough, in some specific inspection fields, such as high-speed vehicle inspection, high-altitude meter reading, large-scale warehousing, etc., it is necessary to raise and straighten the endoscope camera for inspection.

[0003] The probe of an endoscope used for large-caliber detection is often made relatively large, which makes the probe heavy. Therefore, it is difficult to realize the steering function of the probe. On the other hand, the probe needs to be steerable while being easy to store and transport. Therefore, the insertion tube needs to be made of soft tube material. However, the insertion tube made of soft material is difficult to support the heavy probe, resulting in the inability to realize long-distance or upward detection and exploration purposes.

[0004] In view of the above technical problems, for example, an endoscope is disclosed in the announcement number CN209705602U. By arranging a telescopic rod on the outer surface of the insertion tube, the bending strength of the insertion tube is enhanced, so that the heavy probe can be supported without bending, thereby achieving the purpose of long-distance detection and upward detection. At the same time, the bending direction of the steering joint can be controlled by the rocker, the universal ball and the traction rope, so that the probe can perform 360° bending detection, which has the advantage of a wide detection field. In addition, the rocker is set according to the principle of a lever, and the heavy probe can be controlled to achieve steering with only a small force of the finger, so it also has the advantages of convenient operation and labor saving.

[0005] Traditional endoscopes are unable to achieve shaping through the hardness of their own guide wires, and as a result, customers need to use long hard rods such as binding wooden sticks to solve the problem during use. This increases the customer's workload and, more importantly, is inconvenient to carry and store. Utility Model Content
