Description
Technical field
The utility model relates to digital camera accessory technical field, relates to specifically and a kind ofly is used for can arbitrarily changing wide-angle on the digital camera, increases doubly, the switching device of camera lens such as filter.
Background technology
Along with the development of society, the progress of science and technology, digital camera has entered into huge numbers of families more and more widely as popularizing commodity.At present, the focal length of existing digital camera lens is generally 3-10 doubly, in order to obtain longer shooting distance or wider coverage, people need install adapter ring or switching tube usually on the camera lens of digital camera, on the switching tube, photographic accessory is installed again, for example wide-angle, increase doubly or filter assembly etc., to obtain different shooting effects.Existing adapter ring of selling on the market or switching tube it typically is standard component, and an end and the digital camera of switching tube are fixed, and the other end is installed photographic accessory.The switching tube of this form, it is simple in structure, and the length of switching tube can not length be shunk and is remained unchanged.When the camera lens of digital camera during according to the length zoom of captured distance, camera lens can be flexible back and forth in the switching tube of hollow, just such problem occurred this moment, if select the long switching tube of diameter, though the camera lens of digital camera reaches longest distance and also can not conflict on the lens assembly in switching tube the place ahead, but the phenomenon that when using wide-angle lens, can occur " black angle " around the photo of imaging, promptly photo around being blocked by the switching tube and imaging that can not be complete; If select the relatively shorter switching tube of diameter, though there is not " black angle " phenomenon to occur around the photo, but in the time the camera lens of digital camera need being elongated longest distance, " meeting and discussing " phenomenon can appear, be that the camera lens of digital camera and the lens assembly in switching tube the place ahead bump, can damage camera lens and other lens assemblies when serious.
The utility model content
For solving the problems of the technologies described above, the utility model proposes a kind of camera lens of digital camera and lens assembly of switching device front end of can preventing and collide; Can prevent to occur around the photo camera lens conversion equipment of " black angle " phenomenon again simultaneously, the utility model is applicable to that the digital camera with various different type of machines is complementary, and can be along with the difference of different type of machines focal length the length of flexible switching device arbitrarily; And the utility model is simple in structure, and is easy to operate, and the photograph that adopts digital camera of the present utility model to break forth to come is clear and do not have " black angle ", and the utility model can be avoided " meeting and discussing " phenomenon simultaneously.
The utility model is achieved by the following technical solution:
A kind of digital camera lens switching device, it is characterized in that: comprise the regulating ring and the abutment ring that connect successively, a wherein end of described abutment ring is connected with digital camera, the other end of abutment ring is threaded with regulating ring, on an end of regulating ring/abutment ring, be provided with external thread, be provided with the internal thread that mates with external thread on abutment ring/regulating ring, the free end of described regulating ring is connected with lens assembly.
A wherein end of described abutment ring is connected with digital camera through connector, described connector is a set collar, a described set collar wherein end is threaded with no interface digital camera, the other end is threaded with abutment ring, and is provided with the clamp ring that is used to lock camera and switching device in the groove of set collar inwall.
Described external thread is provided with and makes the relatively-stationary retaining ring of regulating ring and abutment ring position.
Be provided with the slip-off preventing alert flag near in the externally threaded starting point place.
The internal diameter that one end has externally threaded regulating ring is identical with the internal diameter of described set collar, and is provided with the standby circle of locking of locking regulating ring and camera in the inner groovy of regulating ring inwall.
The axial distance of described regulating ring and abutment ring is complementary, and in the time of among regulating ring/abutment ring screws in abutment ring/regulating ring fully, the axial distance sum of abutment ring and regulating ring is greater than the axial distance of single abutment ring or regulating ring.
Described clamp ring or lock standby circle and be O shape rubber ring.
Advantage of the present utility model is:
1, because the utility model adopts abutment ring and regulating ring to be in turn connected into switching device, can adjust the length of whole switching device like this between regulating ring and the abutment ring by the mode of turn screw thread, with existing only be that a standard component and switching tube that length can not change are compared, adjust the length distance of switching device, in the time of both can having realized adopting the wide-angle lens assembly to take pictures and do not have " black angle " phenomenon to take place, when simultaneously, adopting the teleconverter lens assembly to take pictures and the camera lens of digital camera is collided with the teleconverter lens assembly and damage the accident generation of camera; Simultaneously, abutment ring and regulating ring all can be separately and digital camera coupling and make annexes such as being used for installing auxiliary lens or light shield and length is shorter, " black angle " phenomenon more can not appear in the photo of breaking forth, and makes each parts of the present utility model be able to be utilized more fully simultaneously yet.
2, because the utility model adopts abutment ring to be connected with digital camera through connector such as set collar, help to make switching device to fix with digital camera better; On described external thread, retaining ring is installed,, adopts retaining ring can make regulating ring and abutment ring position relative fixed more and do not slide when regulating ring and abutment ring turn during to the fixed position.
3, to have the internal diameter of externally threaded regulating ring identical with the internal diameter of described set collar for an end, and clamp ring and the standby circle of locking are installed in the inner groovy of the groove of set collar and regulating ring, thereby when using set collar or regulating ring individually or simultaneously and have an effect that the phase function is fixed with switching device better.
4, since the utility model near being provided with the slip-off preventing alert flag in the externally threaded starting point place, when making switching device be in longest distance, prevent from effectively to continue turn and the phenomenon that comes off accidentally takes place when the screw thread between turn regulating ring and the abutment ring.
5, because the axial distance of regulating ring and abutment ring is complementary, in the time of among regulating ring/abutment ring screws in abutment ring/regulating ring fully, the axial distance sum of abutment ring and regulating ring is greater than the axial distance of single abutment ring or regulating ring.Make the length of switching device have maximum flexible scope like this, further guarantee to be complementary with the digital camera of various different models, focal length.
6, the utility model is applicable to that the no interface digital camera with various different type of machines is complementary, and can be along with the difference of different type of machines focal length the length of flexible switching device arbitrarily; And the utility model is simple in structure, and is easy to operate, and the photograph that adopts no interface digital camera of the present utility model to break forth to come is clear and do not have " black angle ".
