Background technology
The digital camera that generally uses is equipped with a liquid crystal display screen, is used for observing the situation of finding a view of digital camera or browsing the photo of having taken for the cameraman is convenient on it at present.But present digital camera self is not with the dimmer of liquid crystal screen, so under sunshine or high light, the liquid crystal screen can not see Chu, has influenced photographic effects.People develop the digital camera liquid crystal screen dimmer of various different structures for this reason, be used for overcoming this defective of digital camera, its structure generally comprises window board that is connected digital camera liquid crystal screen zone and the shadow shield that is arranged on the window board, shadow shield is by the top of the window edge that is hinged on window board respectively, the left side, three plate bodys in right side constitute, the hinged place of left side and two plate bodys in right side is provided with the torsion spring that straightens usefulness automatically, the nonhinged edge of top board body has the fastening part that fixes with window board, constitutes the awning shape structure of a liquid crystal screen front when three plate bodys straighten.The sunscreen protection device of the digital camera liquid crystal screen that No. the 200520054935.4th, the Chinese patent of the applicant's application, it is a kind of improved similar dimmer, its design feature is shadow shield by the top of the window edge that is hinged on window board respectively, down, left side, four plate bodys in right side constitute, down, the hinged place of left side, three plate bodys in right side is provided with the torsion spring that straightens usefulness automatically, tube is looked in the rectangle shading that constitutes a liquid crystal screen front when four plate bodys straighten.This class dimmer also can have been sealed up slide on the window of window board, work the dustproof anti-scratch effect of liquid crystal screen when taking.The dimmer of the digital camera liquid crystal screen that No. the 200620063133.4th, the Chinese patent of the applicant's application, on the basis of existing structure, done further improvement, its design feature is to establish an interlayer cavity in the top shading plate body, be sliding combined with a slice on the interlayer cavity and have the plate lens of amplification, liquid crystal screen the place ahead can be pulled out and down be folded to plate lens as liquid crystal screen magnifier.
Above-mentioned all existing digital camera liquid crystal screen dimmers, it is directly connected to the syndeton on the window board in digital camera liquid crystal screen zone, general bail or the fixture block of adopting is clamped on the draw-in groove of camera, or adopt the double-sided self-adhesive sticker that window board is clinged around the liquid crystal screen, or adopt a link that extends to be threaded onto on the tripod connecting hole of camera bottom surface, or the like.But syndeton all is not convenient for dimmer and more directly is installed to digital camera liquid crystal screen zone or disassembles from digital camera liquid crystal screen zone more continually on the existing window board, has brought inconvenience to use.
Summary of the invention
For being not convenient for of overcoming that existing digital camera liquid crystal screen dimmer exists more directly is installed to digital camera liquid crystal screen zone or disassembles from digital camera liquid crystal screen zone more continually, bring inconvenient defective to use, the purpose of this utility model provides a kind of magnetic-type dimmer of improved digital camera liquid crystal screen, can overcome the defective of prior art.
The utility model is that the technical scheme that its technical matters of solution is adopted is: a kind of magnetic-type dimmer of digital camera liquid crystal screen, it is characterized in that: comprise the ferromagnetic or magnetic material spare that is used to cling at digital camera liquid crystal screen periphery place, with with dimmer main body ferromagnetic or that magnetic material spare magnetic cooperates, wherein the dimmer main body cooperates the window board of window and the shadow shield that is arranged on the window board to constitute by having digital camera liquid crystal screen, shadow shield is at least by the top of the window edge that is hinged on window board respectively, the left side, three plate bodys in right side constitute, at least the hinged place of left side and two plate bodys in right side is provided with the torsion spring that straightens usefulness automatically, have on the medial surface of window board and magnetic position ferromagnetic or that magnetic material spare magnetic cooperates, the nonhinged edge of top board body has the fastening part that fixes with window board.
The shadow shield of technique scheme can be by the top of the window edge that is hinged on window board respectively, down, left side, four plate bodys in right side constitute, down, the hinged place of three plate bodys in left side and right side is provided with the torsion spring that straightens usefulness automatically.
Establish an interlayer cavity in the top board body of technique scheme, be sliding combined with the plate lens that a slice has amplification on the interlayer cavity, liquid crystal screen the place ahead can be pulled out and down be folded to plate lens as liquid crystal screen magnifier.
Ferromagnetic or the magnetic material spare of technique scheme can adopt any suitable appearance.Ferromagnetic or magnetic material spare can be ferromagnetic material, as iron, steel, nickel, cobalt etc.; Can be the magnetic material also, as permanent magnet.
The magnetic position of technique scheme can be a permanent magnet position, also can be the position that a back side is provided with permanent magnet.
The beneficial effects of the utility model: because ferromagnetic or magnetic material spare are clinged at digital camera liquid crystal screen periphery place, just the dimmer main body is put on the digital camera liquid crystal screen when needing shading, magnetic position on it will attract ferromagnetic or magnetic material spare and the dimmer main body is fixed, when not needing the dimmer main body to be fixed on the camera, with hand dimmer main body one is taken off, the magnetic position of dimmer will separate with ferromagnetic or magnetic material spare and unload down, be convenient to especially that dimmer is installed more continually or the situation of dismounting more continually, also brought convenience to use; Ferromagnetic or magnetic material spare can be made very small and exquisite part, so cling for a long time at digital camera liquid crystal screen periphery place, also can not have influence on the overall appearance of digital camera, and this also is another advantage that the utility model is different from the other technologies scheme.
The utility model is described in further detail below in conjunction with drawings and Examples.
