Detailed Implementation

[0023] The present invention will be further described below with reference to the embodiments.

[0024] Please refer to Figures 1-5. This utility model provides a telescopic 360-degree industrial endoscope, including a display body 1, a handle 2, a connecting tube 3, and a camera head 4. The handle 2 is fixedly connected to the bottom of the display body 1, the connecting tube 3 is fixedly installed at the rear of the display body 1, the camera head 4 is fixedly installed at the end of the connecting tube 3, and a telescopic mechanism 5 is provided on the connecting tube 3.

[0025] As further shown in Figures 2, 3, 4 and 5, it is worth noting that the telescopic mechanism 5 includes a fixing ring 501, which is fixedly connected to the outside of the connecting pipe 3. A connecting cylinder 502 is fixedly connected to the front side of the fixing ring 501, and the connecting cylinder 502 is set on the outside of the connecting pipe 3 through the fixing ring 501. The outer surface of the connecting cylinder 502 is provided with an external threaded groove 503. Four limiting grooves 504 are provided on the connecting cylinder 502 and are evenly distributed. The limiting grooves 504 are open at the front of the connecting cylinder 502. A sleeve 506 is slidably fitted onto the front end of the fixing ring 501 outside the connecting tube 3. A connecting ring 507 is fixedly connected to the front end of the sleeve 506. A limiting ring 509 is fixedly connected to the rear end surface of the sleeve 506. A rotating cylinder 508 is provided at the rear end of the sleeve 506. A rotating groove 5010 is provided on the rotating cylinder 508 corresponding to the limiting ring 509. The rotating cylinder 508 passes through the limiting ring 509 and the rotating groove 5010. The sleeve 506 is rotatably mounted on the sleeve 506. A limiting block 5011 is fixedly connected to the rear end of the inner side of the sleeve 506. Four limiting blocks 5011 are provided on the inner wall of the sleeve 506, matching the limiting grooves 504. The sleeve 506 is slidably mounted on the inner side of the limiting grooves 504 through the limiting blocks 5011. An internal thread groove 5012 is provided on the inner surface of the rotating cylinder 508. A spring 505 is provided between the rear end of the connecting ring 507 and the front end of the connecting cylinder 502. The spring 505 is sleeved on the outside of the connecting pipe 3 through the sleeve 506. The internal thread groove 5012 is matched with the external thread groove 503. The internal thread groove 5012 is threadedly connected to the connecting cylinder 502 through the external thread groove 503.

[0026] During operation, the rotating drum 508 enables the internal thread groove 5012 and the external thread groove 503 to rotate in a threaded engagement. The limiting block 5011 precisely positions the connecting cylinder 502 within the limiting groove 504. At the same time, the fixing ring 501 is fixedly connected to the connecting pipe 3, ensuring the stability of the structure. The rotation of the rotating drum 508 causes the connecting cylinder 502 to slide, which in turn causes the fixing ring 501 to push the connecting pipe 3, driving the shooting head 4 to make precise extension and retraction adjustments inside the part. Simultaneously, the movement of the threads enables real-time precise positioning of the extension and retraction adjustment process.

[0027] This solution has the following working process: When this device is used, the camera head 4 is inserted into the part for testing. With the help of fingers, the sleeve 506 is held, and the rotating cylinder 508 is rotated. At this time, by rotating the rotating cylinder 508, the internal thread groove 5012 and the external thread groove 503 are threadedly connected. In addition, the limiting block 5011 limits the connecting cylinder 502 in the limiting groove 504. At the same time, the fixing ring 501 is fixedly connected to the connecting tube 3, so that the rotating cylinder 508 rotates and drives the connecting cylinder 502 to slide. In turn, the fixing ring 501 pushes the connecting tube 3 and drives the camera head 4 to extend and retract inside the part. Through its threaded movement, the extension and retraction adjustment process can be positioned in real time. At the same time, the elastic force of the spring 505 is used to adjust the extension and retraction of the connecting cylinder 502, thereby improving the stability of its extension and retraction process. In addition, the setting of the connecting ring 507 can further improve the stability of the extension and retraction process when adjusting the extension and retraction of the connecting tube 3. The extension and retraction adjustment process is simple to operate and easy to use.

[0028] In summary, the meticulously designed telescopic mechanism 5 enables this convenient telescopic adjustment mechanism. It not only allows operators to easily and precisely adjust the telescopic head 4 according to the actual detection depth, but also significantly improves the overall ease of use of the device. This telescopic mechanism 5 provides precise positioning during the adjustment of the telescopic head 4, ensuring high-precision performance in various detection environments. Its design fully considers both ease of operation and detection accuracy, making even complex detection tasks easy and straightforward. This innovation not only improves work efficiency but also reduces errors that may be caused by improper operation, thereby ensuring the reliability of the detection results. In practical applications, operators can experience the convenience brought by this telescopic mechanism, which makes the entire detection process smoother and sets a new standard for the accuracy of detection equipment.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
