[0034] The embodiment provides an optical cabin end face protection device for preventing the optical cabin end face from being damaged.

The threaded holes a are uniformly arranged along the circumference of the optical cabin end face, the threaded holes b are uniformly arranged along the circumference of the optical cabin end face, and the diameter of the circumference where the threaded holes a are located is smaller than the diameter of the circumference where the threaded holes b are located.
[0036] As shown in Figure 1 and Figure 2 , the protection device 1 is annular. In the embodiment, the outer diameter of the annular structure is 1-2 mm larger than the outer diameter of the optical cabin end face, and the inner diameter of the annular structure is 1-2 mm smaller than the inner diameter of the optical cabin end face. In the annular structure, one end face is a plane, and the other end face is a stepped face. The plane end is butt jointed with the optical cabin end face, the stepped end is butt jointed with the mounting surface of the test tool, and the stepped end corresponds to the convex structure of the mounting surface of the test tool. In the embodiment, the outer periphery and the inner periphery edge of the annular structure are provided with a circular arc chamfer, which can avoid that the edge of the protection device 1 scratches the optical cabin end face.
[0037] A plurality of through holes a2 are machined on the annular structure. The through holes a2 correspond to the threaded holes a on the optical cabin end face one by one. The diameter of the through holes a2 is consistent with the diameter of the threaded holes a. When the screws are installed or dismounted, the screws are threadedly matched with the threaded holes a through the through holes a2, so that damage to the surrounding of the threaded holes a can be prevented.
[0038] The annular structure is machined with clearance holes 4 corresponding to the two positioning pins one by one. The clearance holes 4 are provided with O-rings a, which can avoid direct contact between the positioning pins and the inner circumferential surface of the clearance holes 4, and prevent the positioning pins from being damaged.
[0039] The ring structure is provided with two or more through holes b3 on the ring structure. The through holes b3 correspond to any two or more threaded holes b of the optical cabin end face. An O-ring b is arranged in each through hole b3, and the two ends of the O-ring b protrude from the two ends of the corresponding through hole b3, so that a gap is formed between the flat end of the ring structure and the optical cabin end face, and between the mounting surface of the protection device 1 and the mounting surface of the test tool, thereby avoiding direct contact between the flat end of the ring structure and the optical cabin end face, and between the stepped surface of the ring structure and the mounting surface of the test tool, and further reducing damage to the optical cabin end face and the mounting surface of the test tool caused by direct contact. The through holes b3 are used to mount the protection device 1 on the optical cabin end face, and the screws are screwed into the through holes b provided with the O-rings b and the corresponding threaded holes b to complete the fixation. The through holes b are used to mount the optical cabin and the protection device 1 on the mounting surface of the test tool.
[0040] Meanwhile, the ring structure is further provided with a gap b5 corresponding to the gap a on the optical cabin end face. The gap b is used to accommodate the connecting line connected to the optical cabin.
[0041] Embodiment 2:
[0042] The embodiment provides an optical cabin end face protection device based on the protection device 1 in embodiment 1.
[0043] The protection device 1 in the embodiment includes two buffer pads. The buffer pads are used to replace the O-rings in the through holes b3.
[0044] The two buffer pads are arranged on the two end faces of the ring structure by adhesion. The buffer pads are made of materials having a buffering effect.
[0045] The buffer pads are used to avoid direct contact between the flat end of the ring structure and the optical cabin end face, and between the stepped surface of the ring structure and the mounting surface of the test tool, and further reduce damage to the optical cabin end face and the mounting surface of the test tool caused by direct contact.
[0046] In conclusion, the above is only a preferred embodiment of the utility model, and is not used to limit the protection scope of the utility model. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the utility model should be included in the protection scope of the utility model.
