Abstract
The utility model proposes optical filter stationary installation, comprise flexible fastening circle and holder, flexible fastening circle is oval, flexible fastening circle is provided with projection along on oval long axis direction, holder is provided with fixing ring recess and optical filter mounting groove, flexible fastening circle is arranged on fixing ring recess, holder is also provided with the projection slide opening coordinated with projection, is printing opacity through hole in the middle of holder.The utility model is primarily of flexible fastening circle and holder composition, structure is simple, adult is low, as long as pressing projection when the utility model uses, make because flexible fastening circle is resilient material, so flexible fastening circle can become circle under force, then just optical filter can be put on optical filter mounting groove, finally unclamp projection, flexible fastening circle becomes again oval, because the minor axis of ellipse is shorter than major axis, so flexible fastening circle short-axis direction can push down the edge of optical filter, fix optical filter, simple to operate, change optical filter convenient.
Description
Technical field
The utility model relates to stationary installation, particularly optical filter stationary installation.
Background technology
Optical filter is that plastics or glass sheet add special dye again and make, and Red lightscreening plate can only allow ruddiness pass through, and so analogizes.Sometimes as required, change different optical filters, existing optical filter fixture structure is complicated, and not easily changes optical filter.But the effect of optical filter is very large, is widely used in photographic circle.Therefore, for the deficiency that prior art exists, need to design a kind of structure simple, and be convenient to the stationary installation changing optical filter.
Utility model content
The utility model proposes optical filter stationary installation, solve optical filter fixture structure in prior art simple, change the defect of optical filter inconvenience.
The technical solution of the utility model is achieved in that
Optical filter stationary installation, comprise flexible fastening circle and holder, flexible fastening circle is oval, flexible fastening circle is provided with projection along on oval long axis direction, holder is provided with fixing ring recess and optical filter mounting groove, flexible fastening circle is arranged on fixing ring recess, holder is also provided with the projection slide opening coordinated with projection, is printing opacity through hole in the middle of holder.
Further, the end of described projection is arc tips.
Further, described arc tips is provided with slippage prevention device.
Further, described slippage prevention device is arc-shaped gear.
The beneficial effects of the utility model: the utility model is primarily of flexible fastening circle and holder composition, structure is simple, adult is low, as long as pressing projection when the utility model uses, make because flexible fastening circle is resilient material, so flexible fastening circle can become circle under force, then just optical filter can be put on optical filter mounting groove, finally unclamp projection, flexible fastening circle becomes again oval, because the minor axis of ellipse is shorter than major axis, so flexible fastening circle short-axis direction can push down the edge of optical filter, fix optical filter, simple to operate, replacing optical filter is convenient.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the structural representation of the utility model optical filter stationary installation;
Fig. 2 is the structural representation of Fig. 1 Elastic retainer plate;
Fig. 3 is the structural representation of holder in Fig. 1.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
With reference to Fig. 1-3, optical filter stationary installation, comprise flexible fastening circle 1 and holder 2, flexible fastening circle 1 is oval, flexible fastening circle 1 is provided with projection 3 along on oval long axis direction, and holder 2 is provided with fixing ring recess 4 and optical filter mounting groove 5, and flexible fastening circle 1 is arranged on fixing ring recess 4, holder 2 being also provided with the projection slide opening 6 coordinated with projection 3, is printing opacity through hole 7 in the middle of holder 2.The utility model forms primarily of flexible fastening circle 1 and holder 2, structure is simple, adult is low, as long as pressing projection 3 when the utility model uses, because flexible fastening circle 1 is resilient material making, so flexible fastening circle 1 can become circle under force, then just optical filter can be put on optical filter mounting groove 5, finally unclamp projection 3, flexible fastening circle 1 becomes again oval, because the minor axis of ellipse is shorter than major axis, so flexible fastening circle 1 short-axis direction can push down the edge of optical filter, fix optical filter, simple to operate, change optical filter convenient.
In the present embodiment, the end of described projection 3 is arc tips.The end of projection makes arc tips, more comfortable when hand can be allowed to press.
In the present embodiment, described arc tips is provided with slippage prevention device 8.
In the present embodiment, described slippage prevention device 8 is arc-shaped gear.Arranging when can prevent finger presses of slippage prevention device 8 skids off, and makes comfort level when arc-shaped gear can improve finger presses.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
