Abstract
The utility model discloses a dustproof device of a digital single-lens reflex camera, comprising a totally-enclosed aperture which is fixed on the lower surface of a step between a plate surface and an electric contact ring plate, wherein the outer edge of the totally-enclosed aperture is provided with a shifting lever vertical to the totally-enclosed aperture; the shifting lever is used for being inserted in a lens mount; a return spring is connected between the shifting lever of the totally-enclosed aperture and a camera body; and the totally-enclosed aperture is fixedly connected with the camera body through an adhesive layer, a clamp spring or a bolt. After the lens is mounted, the shifting lever is inserted in the lens mount. When the lens is rotated, the shifting lever drives the aperture to open or close along with the opening and closing of the lens. Therefore, when the lens is not used, the camera in the lens mount is in closed condition, the dust is prevented from entering the camera body, and a sensitive plate is effectively protected; when the lens is mounted, the camera is in open condition, the imaging quality is ensured.
Description
Technical field
The utility model relates to the digital slr camera in the camera, specifically, relates to a kind of parts of digital single anti-digital camera fuselage.
Background technology
Existing digital slr camera does not have special dust guard between camera lens and photographic plate (ccd).Because the frequent camera lens of changing does not notice slightly during replacing that dust is easy to enter fuselage interior and sticking staying on the photographic plate, occurs stain when making imaging on the picture, has a strong impact on shooting quality.The user not only will be careful in use very much, also needs often photographic plate to be purged cleaning, perhaps uses cotton swab, the direct wiping of lens paper.But these methods all are difficult to fully the dust on the photographic plate be cleaned out, even also can stay cut and trace when cleaning, cause damage.
At present rare special solution at the problems referred to above can only regularly arrive the cleaning maintenance of maintenance department of manufacturer, and the regular factory that returns clears up very bothersomely, not only can not fundamentally avoid contamination by dust, and consuming time, expense is also higher.Some manufacturers are used for the clean feel tabula rasa in the mode that digital slr camera adds such as the ultrasound wave shake now, but because ultrasonic vibration can only have tangible effect for the dust on adhering sense tabula rasa surface, and, just be difficult to solve as water mark etc. for the more intense dirt of other adhesion.And owing to increase ultrasonic vibration system, such slr camera cost can be very high.
The utility model content
The technical problems to be solved in the utility model provides a kind of digital slr camera dust guard that is installed in the fuselage camera lens bayonet socket; this device can cooperate the use of digital slr camera fully; neither influence image quality; can prevent fundamentally that again dust etc. from entering camera lens, effectively protected photographic plate.
In order to solve the problems of the technologies described above, the utility model is achieved by following technical scheme:
A kind of digital slr camera dust guard, constitute by device body, described device body comprises for fixing to the totally enclosed type aperture on the step lower surface between and the electric contact girth sheets surperficial along plate, described totally enclosed type aperture outer rim is provided with the driving lever perpendicular to the totally enclosed type aperture, and described driving lever is used to insert the camera lens bayonet socket.
Be connected with retracing spring between the driving lever of described totally enclosed type aperture and the fuselage.
Described totally enclosed type aperture is affixed by adhesive layer and fuselage.
Described totally enclosed type aperture is affixed by jump ring and fuselage.
Described totally enclosed type aperture is affixed by bolt and fuselage.
The quantity of the aperture blades of described totally enclosed type aperture is 3～16.
The beneficial effects of the utility model are:
Install after the camera lens, the driving lever of this device inserts in the bayonet socket of camera lens.When rotating camera lens, along with the folding of camera lens, driving lever also can drive the aperture opening and closing of this device.Like this, when not using camera lens, this device that is arranged in the camera lens bayonet socket is closed condition, prevents that dust from entering fuselage, has protected photographic plate effectively; When loading onto camera lens, this device is an opening, guarantees image quality.And this device is installed in after the fuselage interior, does not need to carry out special operation, and is easy to operate, cheap along with the installation of camera lens just can be handled the switch of this device, is fit to promote.

Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail:
As depicted in figs. 1 and 2, the utility model discloses a kind of digital slr camera dust guard, comprise for fixing to along the totally enclosed type aperture 1 on the lower surface of step 8 between plate surface 7 and the electric contact girth sheets 6, described totally enclosed type aperture 1 outer rim is provided with the driving lever 3 perpendicular to totally enclosed type aperture 1, and described driving lever 3 is used to insert camera lens bayonet socket 4.
As shown in Figure 3 and Figure 4, totally enclosed type aperture 1 is identical with the aperture of general camera lens inside, also is made up of the thin metal blade of a plurality of overlapped arcs, and metal blade connects pin, and pin slides in presetting track.Therefore, the clutch of aperture blades 2 can change the size in central circular aperture.In order to reach the purpose that fully prevents dust, the utility model need be selected totally enclosed type aperture 1 for use, promptly aperture blades 2 can be fully closed aperture type, its thickness is generally 2mm.The quantity of the aperture blades 2 of described aperture 1 is generally 3～16.
Described totally enclosed type aperture 1 can also be provided with a retracing spring, and when camera lens 9 was unloaded, retracing spring was retracted to the original position naturally, aperture blades 2 is rebounded and closed more intact.
As shown in Figure 5 and Figure 6, with CANON 350D, the digital slr camera of Canons such as EF 17-40/F4 is an example, and the installation site of the utility model on camera body is described.The utility model is that totally enclosed type aperture 1 is installed in reflector case 5 outsides, is fixed on along the lower surface of the step 8 between plate surface 7 and the electric contact girth sheets 6.Utilize the function that totally enclosed type aperture 1 can adjustment aperture, insert camera lens bayonet sockets 4 by driving lever 3, camera lens 9 rotates and stirs driving lever 3 simultaneously, drives aperture blades 2 foldings, reaches this device along with camera lens 9 unlatchings to be installed, and camera lens 9 unloads the purpose of closing.
