Description
Technical field
The utility model relates to photo-optics apparatus field, specifically refers to a kind of optical filter apparatus for fast switching.
Background technology
Existing camera installation is in order to meet the use needs in daytime and evening simultaneously, usually before camera lens, infrared fileter is provided with, time by day, cutoff filter is switched to photosensitive sites, when evening, is switched to photosensitive sites by infrared by optical filter.More conventional way is at present: optical filter is placed in support or holds in the device of optical filter, with gland, optical filter is compressed again, be threaded outside gland, gland and support or hold optical filter device between fixed by screw thread, when keeping in repair or change optical filter, need repeatedly, repeatedly to turn helicitic texture.Accordingly, can produce consuming time longer in the process used, the problems such as efficiency is lower, complex operation.
Utility model content
The purpose of this utility model is to provide a kind of optical filter apparatus for fast switching, avoids the loaded down with trivial details of screw fixation method, has the advantages that structure is simple, replacing is convenient and with low cost.
The utility model can be achieved through the following technical solutions:
A kind of optical filter apparatus for fast switching, comprise optical filter fixed support, sliding axle, step motor and drive link, optical filter fixed support and sliding axle are slidably connected, and one end of drive link is connected with step motor.Described drive link outside surface is fixed with limit spring; Described optical filter fixed support is connected by web member with drive link, described web member bag two angular adjustment spacer and fixed connecting rod, and described fixed connecting rod is connected with optical filter fixed support; The end that described fixed connecting rod is being connected with angular adjustment spacer is provided with spacing hole, and described spacing hole is provided with internal thread, and described drive link, limit spring are rotationally connected through spacing hole and web member.The introducing of web member, achieves the transmission between optical filter fixed support and step motor, drives optical filter fixed support to move around on sliding axle, provides the space that optical filter switches fast; By the introducing of spacing hole and limit spring, both the threaded mobile effect of tool, overcame again the loaded down with trivial details of threaded adjusting; By the introducing of angular adjustment banking stop, structure is simple, and the function that engaging location has nut is simultaneously more simple compared with nut again.
Preferably, described limit spring is provided with the spacing line of linear at two ends, and described spacing line is parallel with described drive link.The introducing of spacing line, can be implemented in end points that limit spring moves to two ends and realizes self-actuating brake and stop, avoiding because limit spring is occurred locking state by excessive compression.
Preferably, described angular adjustment spacer is flexibly connected by rotation axis with fixed connecting rod, the angle variation range that two angular adjustment spacers are formed is 0 degree to 180 degree, angular adjustment is very convenient, angle opens the rotation that can realize drive link, and angle reduces the engaging positioning function that can realize nut and have.
A kind of optical filter apparatus for fast switching of the utility model, compared with existing switching device of optical fiber, has following beneficial effect:
The first, structure is simple, replaces conventional screw thread, be aided with web member and carry out spacing by the mode of fixing limit spring on drive link, realizes back and forth changing location;
The second, easy switching, by opening step motor, mobile spectral filter fixed support can be driven to move, carry out the replacing of optical filter, the effect of limit spring avoids the locking state in handoff procedure;
Three, with low cost, this apparatus structure simplicity of design, can time processing shaping, effectively cost-saving.
Accompanying drawing explanation
Accompanying drawing 1 is the decomposition texture schematic diagram of a kind of optical filter apparatus for fast switching of the utility model;
Accompanying drawing 2 is the structural representation of the web member of a kind of optical filter apparatus for fast switching of the utility model;
