Description

Technical Field

[0001] The utility model relates to the technical field of optical equipment, in particular to a fixing device for a folding tube 45-degree reflector. Background Art

[0002] A folded tube 45 degree reflector is an optical component that is usually used to change the direction of light path and reflect light at a 90 degree angle.

[0003] When traditional reflectors are installed on folding tubes, ordinary clips are usually used to complete this operation. Due to the structural characteristics and fixing principles of the clips themselves, the lens is not in a state of uniform stress. Under such uneven stress, the lens will inevitably produce a certain degree of deformation. Once the lens is deformed, it will cause the light spot to shift. In addition, when using clips to fix the lens, it will be extremely inconvenient in the gluing process. The fixing method makes it difficult to evenly apply glue to the connection between the lens and the folding tube. If the glue is unevenly applied, it is easy to have a tight seal in some places and gaps in other places. The folding tube often needs to ensure good airtightness. Once such uneven gluing occurs, it is very easy to cause air leakage at the tube mouth in the later stage. Therefore, a fixing device for a 45-degree reflector on a folding tube is proposed to solve the above problems. Utility Model Content
