Description
Technical field
The present invention relates to the accessory of photographic equipment, specifically a kind of Multifunctional lens cover for macro lens cameras such as slr camera, long burnt camera, single electric cameras.
Background technology
The macro lens camera as slr camera, long burnt camera, single electric camera etc. generally used at present, be typically equipped with when not taking be used to hiding the lens cap of protection phtographic lens, and the most general lens cap is the separable lid that a card fits over camera lens the place ahead.In order to prevent the separable lens losing of cover, so the lens cap of flip-shell occurred; Because often having or be designed with, the lens cap of flip-shell blocks the shade function that some veiling glares enter camera lens, so the Multifunctional lens cover that possesses shaded effect has just been arranged.
No. 201120299364.6 disclosed a kind of lens cap that possesses shaded effect of Chinese patent, structure comprises that main ring, abutment ring, shadow shield, torsion spring, lock release switch, abutment ring is fixed on the main ring rear side, the upper and lower sides of main ring front side respectively is provided with fixing shading convex edge, a pair of shadow shield is hinged on respectively on the left and right sides hinged seat of main ring front side, torsion spring set is located on the jointed shaft of shadow shield, the one pin heads on shadow shield one pin and heads on hinged seat, and lock is released switch and is located at main ring top, does coordinating of locking or release with shadow shield.The shortcoming of this lens cap is: the one, and lens cap needs the cameraman to close up two shadow shields in left and right with hand when closed, and then makes shadow shield be released switch locking by lock, cumbersome in operation; The 2nd, the shading degree of protracting of shading convex edge and shadow shield is less, and there is the shading drain region in the both side ends that particularly goes up the shading convex edge, so its shaded effect is not good.
Summary of the invention
In order to overcome the existing lens cap that possesses shaded effect, there is the not good defect of troublesome poeration, shaded effect, the purpose of this invention is to provide a kind of Multifunctional lens cover of improved macro lens camera, can overcome the defect of prior art.
The technical solution adopted for the present invention to solve the technical problems is: a kind of Multifunctional lens cover of macro lens camera, by the main ring be used to being connected to the camera lens outside and the lid be hinged on main ring, formed, the main ring top is provided with hinged seat, lid is hinged on the main ring hinged seat by its upside, lid downside or main ring bottom are provided with the lock cooperatively interacted and release switch, lid is sealed on the camera lens form of main ring when closed, it is characterized in that: lid is by top board, base plate, a pair of shadow shield, control panel, stage clip forms, wherein two shadow shields respectively by its upper articulation in the base plate top side, and two shadow shields can rotate and are superimposed on the base plate top side or rotate and stretch out the base plate both sides around pin joint, control panel is contained in the shadow shield top side, control panel pulls and is connected with the jointed shaft of lid, the control panel bottom surface is provided with the push-and-pull groove and coordinates with the push-and-pull nail on two shadow shields, top board is contained in the control panel top side and fixes with base plate, the top board bottom surface is provided with guidepost and coordinates with the mobile guide groove on control panel, stage clip one end withstands on its other end on control panel and withstands on the top board bottom surface.
The described control panel of technique scheme pulls and is connected with the jointed shaft of lid, can be to pull connection by a soft band.
The described stage clip of technique scheme can be mounted in the spring groove on control panel, on the top board bottom surface, can be provided with the protruding pin coordinated in spring groove, and stage clip is that an end withstands on its other end on control panel and withstands on the protruding pin of top board bottom surface.
On the described lid jointed shaft of technique scheme, can be provided with the clasp coordinated with dog hole on control panel.
On the described lid jointed shaft of technique scheme, can be provided with gear, on the top board bottom surface, can be provided with the damping block coordinated do damping with the tooth section of gear.
The described main ring rear side of technique scheme can be provided with a separable abutment ring, and abutment ring is provided with the screw thread be connected with the camera lens outside, can adopt inserting to be connected between main ring and abutment ring.
Beneficial effect of the present invention: the one, when lid was opened, two shadow shields can stretch out from the lid both sides respectively automatically, and when lid closed, two shadow shields can shrink respectively in lid automatically, in use, have obvious convenience; The 2nd, the shading degree of protracting of lid and shadow shield is larger, and particularly its shading width is also larger, can make the both sides of lid not have the shading drain region of camera lens, so its shaded effect is relatively good; The 3rd, structure is fairly perfect, for service property (quality) provides guarantee; The 4th, be skillfully constructed and practicality, with similar technology, compare, have novel effect.
The invention will be further described below in conjunction with drawings and Examples.
