Abstract
The utility model discloses a sunshade, comprising a sunshade ring formed by a plurality of rings, wherein each ring has an external screw and an internal screw of different diameters, the diameter of the external screw of each ring is smaller than the internal screw, and the rings form a sunshade of pagoda type. When in use, the sunshade can be rotationally connected with lenses. And different filters can be assembled on the rings of the sunshade having corresponding screws. When the sunshade is mounted on lenses, and there is dark angle around, the rings at next part can be rotated, and the sunshade formed by part of the rings can eliminate dark angles.
Description
Technical field
The utility model relates to a kind of camera accessories, relates in particular to a kind of camera lens light shield.
Background technology
Existing camera light shield mainly contains straight barrel-shaped light shield and lotus petal type light shield, more than present light shield to have unique purposes be the special purpose of light shield, can't on light shield, increase the optical filtering of various diameters, also exist when camera lens is used in the burnt section of wide-angle in addition, have the situation at dark angle around the photo.
Summary of the invention
Single at above existing light shield purposes, can't increase the situation of various diameter optical filterings, when present in addition light shield is used in camera lens wide-angle Jiao section, have the situation at dark angle around the photo, the utility model provides a kind of novel shading cover, and this light shield not only purposes is wider, can be fit to the optical filtering of various diameters, and when the burnt section of camera lens wide-angle, do not have the situation at dark angle.
The utility model is achieved in that on a light shield annulus by several different-diameters constitutes, external thread and internal thread are all arranged on each annulus, but the external thread on each annulus is all less than internal thread, the screw-internal thread fit of the external thread of the annulus of each different-diameter and another one annulus, annulus by minor diameter cooperates with larger-diameter annulus, by little and big, finally form the light shield of a pagoda shape.
Directly whole light shield is rotated on the camera lens in use, light shield just can keep the sun off well to the direct projection of camera lens, optical filtering that can the fit on different-diameter on the internal thread of the annulus of different-diameter, in addition when camera lens is used in wide-angle side, if occur dark angle all around, just can take off the annulus above the light shield severally, so just not have dark angle.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing:
This accompanying drawing is an example structure synoptic diagram of the present utility model
Among the figure: 1. annulus, 2. annulus, 3. annulus, 4. annulus, 5. annulus, 6. annulus, 7. annulus, 8. annulus.
Embodiment:
Referring to accompanying drawing, accompanying drawing is the structural representation of embodiment of the present utility model.From accompanying drawing as can be seen, the utility model is by annulus 1, annulus 2, and annulus 3, annulus 4, annulus 5, annulus 6, annulus 7, annulus 8 constitutes.On annulus 5 left sides annulus 4 is arranged, there is annulus 3 on annulus 4 left sides, and there is annulus 2 on annulus 3 left sides, and there is annulus 1 on annulus 2 left sides, and there is annulus 6 on annulus 5 the right, and there is annulus 7 on annulus 6 the right, and there is annulus 8 on annulus 7 the right.
Annulus 1, annulus 2, annulus 3, annulus 4, annulus 5, annulus 6, annulus 7, annulus 8 all is circular, all at left part external thread is arranged, right part has internal thread, and simultaneously the diameter of left side external thread and right part internal thread is different, and the external thread diameter on each annulus left side is all less than the internal thread diameter of right part.The internal thread diameter of annulus 1 right part is identical with the left side external thread diameter of annulus 2, the internal thread diameter of annulus 2 right parts is identical with the left side external thread diameter of annulus 3, the internal thread diameter of annulus 3 right parts is identical with the left side external thread diameter of annulus 4, the internal thread diameter of annulus 4 right parts is identical with the left side external thread diameter of annulus 5, the internal thread diameter of annulus 5 right parts is identical with the left side external thread diameter of annulus 6, the internal thread diameter of annulus 6 right parts is identical with the left side external thread diameter of annulus 7, the internal thread diameter of annulus 7 right parts is identical with the left side external thread diameter of annulus 8, has so just formed the light shield of a pagoda shape.
The utility model, the internal thread of annulus 1 right part cooperates with the external thread on annulus 2 left sides, the internal thread on annulus 2 the right cooperates with the external thread on annulus 3 left sides, the internal thread on annulus 3 the right cooperates with the external thread on annulus 4 left sides, the internal thread on annulus 4 the right cooperates with the external thread on annulus 5 left sides, the internal thread on annulus 5 the right cooperates with the external thread on annulus 6 left sides, the internal thread on annulus 6 the right cooperates with the external thread on annulus 7 left sides, the internal thread on annulus 7 the right cooperates with the external thread on annulus 8 left sides, is exactly a complete light shield like this.
In use,, just can go up the light shield rotation on the camera lens, just can use the external thread of annulus 1 left part of light shield and the corresponding screw-internal thread fit of camera lens.
In addition, when using, to load onto the optical filtering of specification different-diameter, just can directly go up different size diameter optical filtering at annulus 1 to the annulus 8 on any one corresponding circle diameter.
Illustrate, because optical filtering all has the internal thread and the external thread of same diameter, if working as the diameter of screw of an optical filtering and the internal thread diameter on annulus 5 the right matches, just whole light shield is rotated with annulus 6 from annulus 5 and come into two sections, just can rotate the external thread of optical filtering on the internal thread of annulus 5 right parts into then, the external thread on annulus 6 left sides be rotated on the right-hand thread of optical filtering into just can use again.
When light shield is contained in when using on the camera lens, particularly camera lens is when the burnt section of wide-angle is used, dark angle may appear around the photo, so just can be a part of down use of light shield rotation, for example: as the annulus 6 of annulus 5 and back part, annulus 7, annulus 8 rotates together, has just only used just with annulus 1 and annulus 2 annulus 3 annulus 4 these a part of light shields of forming.This just decides according to actual operating position.
In order to be fit to different camera lenses more; the utility model patent can increase or reduce the annulus number of corresponding cooperation in this light shield annulus 1 front; or increasing or reduce the annulus number of corresponding cooperation in this light shield annulus 8 back, this also is within this patent protection.
The feature of this light shield just is light shield by annulus 1, annulus 2, and annulus 3, annulus 4, annulus 5, annulus 6, annulus 7, annulus 8 constitutes, and is assembled into a light shield integral body mutually successively.
