[0002] An endoscope is a diagnostic instrument that integrates traditional optics, ergonomics, precision mechanics, modern electronics, mathematics, and software. It has an image sensor, optical lens, light source illumination, and mechanical devices. It can enter the stomach through the mouth or other natural orifices. Endoscopes can be used to see lesions that cannot be seen by X-rays, so they are very useful to doctors. When using an endoscope, the objective lens needs to be fixed and installed.

[0003] Existing objective lens mounts are prone to loosening during installation and use under vibration or temperature changes, causing the objective lens to slide against the mount, affecting image quality and causing certain adverse effects on users. To address the shortcomings of existing technologies, we propose an adhesive objective lens mount with anti-slip properties. Utility Model Content

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] Example 1, as Figures 1-4 As shown, an adhesive objective lens holder with anti-slip effect includes an endoscope body 1. The operator connects the endoscope to external equipment through a light cone 4 and inserts the mechanical tools used during operation into the mechanical connection port 6, allowing it to move within the mechanical through hole 9. Once the equipment is inside the body, the light guide fiber 12 located inside the fixing hole 20 illuminates the front of the objective lens body 10, facilitating observation by the operator. Multiple sets of cylindrical lenses 13 located inside the mounting groove 11 refract the view observed in front of the objective lens body 10 into the interior of the endoscope body 1. The operator can observe the front of the objective lens body 10 through the eyepiece body 5. Simultaneously, the distance between the sets of cylindrical lenses 13 can be adjusted using copper rings 14 of different lengths, thereby adjusting the refraction accuracy.

[0022] Example 2, as Figures 1-4 As shown, an adhesive objective lens holder with anti-slip effect is provided. The holder 8 facilitates the bonding of the objective lens body 10 by the operator. Then, the conical protrusion on the outer side of the mounting base 18 is engaged with the conical groove on the inner wall of the mounting groove 11, thereby confining the holder 8 inside the mounting groove 11. After engagement, it can effectively prevent the holder from sliding inside the mounting groove 11. At the same time, the connecting cover 7 and the glass protective sheet 17 work together to press the mounting base 18 against the inside of the mounting groove 11. Under the elastic action of the protective pad ring 19, the mounting base 18 is pressed firmly, thereby making it stably installed inside the holder 8. Since the mounting base 18 is made of metal, when the operator needs to replace the objective lens body 10, they only need to use a magnet to hold it and remove it from the inside of the mounting groove 11.

[0023] It should be noted that this utility model is an adhesive objective lens holder with anti-slip effect. In use, firstly, select appropriate cylindrical lenses 13 and copper rings 14 according to the length of the endoscope tube 2, and insert them sequentially into the mounting groove 11. The copper rings 14 separate adjacent sets of cylindrical lenses 13. Then, glue the objective lens body 10 to the inside of the mounting base 18. Place the protective pad ring 19 into the mounting groove 11, and then install the mounting base 18 inside the mounting groove 11, so that the conical protrusion on the outer side of the mounting base 18 engages with the conical groove on the inner wall of the mounting groove 11. The sealing ring 16 abuts against the inside of the connecting cover 7, and the glass protective sheet 17 is placed into the inner wall of the connecting cover 7. The connecting cover 7 is screwed onto the front end of the endoscope tube 2. The glass protective sheet 17 presses against the mounting base 18, and the protective pad ring 19 presses against the rear end of the mounting base 18 in the opposite direction, so that the objective lens body 10 is stably installed inside the mounting groove 11, which plays a role in preventing slippage. Finally, the optical fiber 12 is inserted into the corresponding fixing hole 20, and the endoscope body 1 is connected to the external equipment through the set optical cone 4. Finally, the mechanical tools used during operation are inserted into the mechanical connection port 6 to complete the assembly.
