[0007] Preferably, the inner pin and the outer pin are both existing pin structures, and the outer surface of the outer pin is provided with knurling.
[0008] Preferably, an outer surface of one end of the inner pin is connected to the inside of a mounting hole provided on the main cylinder, and an outer surface of the other end of the inner pin is connected to an inner portion of a mounting hole provided on the outer cover ring.
[0009] Preferably, the outer surface of the outer pin is connected to the inside of the mounting hole provided on the outer cover ring, and one end of the outer pin entering the outer cover ring abuts against the end of the inner pin entering the outer cover ring.
[0010] Preferably, the inner diameters of the mounting hole provided on the outer cover ring and the mounting hole provided on the main cylinder are consistent.
[0011] Compared with the prior art, the utility model has the following beneficial effects:
[0012] This endoscope optical lens is provided with an inner pin and an outer pin. When the outer cover ring and the main cylinder are assembled and installed, firstly, the outer surface of one end of the main cylinder is sleeved inside the outer cover ring. At this time, the mounting hole provided on the main cylinder coincides with the mounting hole provided on the outer cover ring. At this time, the inner pin is inserted into the inside of the mounting hole. One end of the inner pin is in the mounting hole provided on the outer cover ring, and the other end is in the mounting hole provided on the main cylinder. At this time, the outer pin is connected to the inside of the mounting hole provided on the outer cover ring. At the same time, the end of the outer pin entering the outer cover ring abuts against the end of the inner pin inside the outer cover ring. The outer surface of the pin is not knurled, while the outer surface of the outer pin is knurled, so that the inner pin serves to connect the outer cover ring and the main cylinder part, and the outer pin serves to limit the installation of the outer cover ring and the main cylinder part, while preventing the inner pin from moving. The setting of this structure connects the outer cover ring and the main cylinder part by pin connection. The connection method is simple and can improve the connection strength between the two to avoid separation of the two. At the same time, the setting of this structure can ensure the stability of the installation structure and avoid looseness caused by external vibration force, which is convenient for users to assemble and use.
