Abstract

The invention discloses an optical lens accessory, which comprises a cylinder and an annular shell, wherein rotating shafts are arranged on the inner side and the outer side of the outer wall of the cylinder; the outer part of the rotating shaft is connected with a rotating gear through a second torsional spring; a first tooth block and a second tooth block are connected to the two sides of the rotating gear in an engaged mode correspondingly; a fixing base is further integrally installed at the bottom of the outer side of the protective cover; a fixing rod is integrally installed at the bottom of the fixing base; the outer portion of the fixing rod is connected with the inner wall of a reserved groove through a first torsional spring; and the reserved groove is formed in the top end of the outer side of the annular shell in a penetrating mode. According to the optical lens accessory disclosed in the invention, during the using process, the whole protective lens is very convenient to assemble and disassemble, the exterior of the whole protective lens has good shock resistance in the using process, the phenomenon that the whole protective lens is seriously damaged when being subjected to external impact force is avoided, and the phenomenon that installation is loosened cannot occur.

Description

Technical field [0001] The invention relates to the technical field related to optical lenses, in particular to an optical lens accessory. Background technique [0002] An optical lens is a light path system composed of single or multiple concave-convex lenses. According to the imaging principle, the current lens can be divided into a front projection lens, a rear projection lens and a de-imaging lens. Nowadays, the lens is required to be used above the camera and the microscope. When the lens is in use, a protective lens is generally installed outside the barrel of the lens to protect the entire lens. Therefore, generally, the protective lens is also one of the accessories of the entire optical lens; [0003] Although there are many types and quantities of protective lenses on the market, the functions they use are relatively simple, and their installation methods are also very simple. There are still a lot of defects in the overall use process that are worthy of our improvement. ...
