Compared to prior art, the driven member that the driving link of described focusing ring can effectively drive lens barrel rotates the realization focusing; When camera lens occurs when bad, only need the elastic fastening hook on the focusing ring dialled from lens barrel and just focusing ring can be disassembled easily, can not cause the damage of material and the increase of production cost.
Description of drawings
Fig. 1 is the schematic perspective view of the focusing ring that provides of embodiment of the present invention;
Fig. 2 is the schematic perspective view of the lens barrel that provides of embodiment of the present invention;
Fig. 3 is the schematic perspective view of the barrel assembly that provides of embodiment of the present invention.
Embodiment
Below with reference to the drawings, the present invention is described in further detail.
See also Fig. 1, the focusing ring 100 that embodiment of the present invention provides, it comprises a substrate 10, an external annulus 20 and an internal ring wall 30.
Described substrate 10 is an annular, and it comprises that a upper surface 11 and is opened in the camera aperture 12 of these upper surface 11 centers, and described camera aperture 12 usefulness are passed for light.
Described external annulus 20 is vertically located on substrate 10 outer rims, is provided with the uniform groove 21 in a plurality of intervals on the outer wall of external annulus 20, is used to increase the friction force when rotation focusing ring 100.
Described internal ring wall 30 is sheathed in the external annulus 20, and is vertically located on the upper surface 11 of camera aperture 12 peripheries of substrate 10.Be respectively equipped with at least one driving link 31 and at least one opening 32 on the inwall of described internal ring wall 30.In the present embodiment, described driving link 31 and opening all are two, and are formed on symmetrically respectively on the inwall of internal ring wall 30.This driving link 31 is a limit guide rail.Extend upward formation one elastic fastening hook 33 along the direction perpendicular to substrate 10 upper surfaces 11 in each opening 32 on described internal ring wall 30, described elasticity elastic fastening hook 33 is made for resilient material, as: elastoplast or metal.This elasticity elastic fastening hook 33 radially extends a projection 331 along this internal ring wall 30.
See also Fig. 2, embodiment of the present invention also provides a lens barrel 40 that matches with focusing ring 100.Described lens barrel 40 comprises a cylindrical shell 42, a shoulder hole 43 and a loop order 44.Described cylindrical shell 42 is an annulated column shape, and described shoulder hole 43 axially runs through described cylindrical shell 42, is used to place eyeglass, and allows light pass.The outside at cylindrical shell 42 radially inwardly offers described loop order 44 along it, also be provided with at least one driven member 41 on the lens barrel 40, described driven member 41 is a fixed leg, this driven member 41 embeds in the described loop order 44 along the axial component of cylindrical shell 42, and the end of driven member 41 protrudes from the lateral surface of cylindrical shell 42, is used for matching with driving link 31 on the focusing ring 100.In the present embodiment, with driving link 31 corresponding driven members 41 be two, and the symmetry be formed on the lens barrel 40.
See also Fig. 3, when this focusing ring 100 used, the internal ring wall 30 of described focusing ring 100 was sheathed on outside the cylindrical shell 42 of described lens barrel 40, and focusing ring 100 and lens barrel 40 are fitted together.Wherein, the projection 331 on the described elastic fastening hook 33 is sticked on the loop order 44 of described cylindrical shell 42 ends, is used to limit focusing ring 100 and moves in the optical axis direction generation relative to lens barrel 40.Described driving link 31 closely is arranged in the driven member 41 of lens barrel 40 wherein, and when rotating focusing ring 100, the driven member 41 that driving link 31 drives on the lens barrel 40 rotates the realization focusing.Be appreciated that the driving link 31 on the focusing ring 100 that embodiment of the present invention provides can be fixed leg, the driven member 41 on the lens barrel 40 can be limit guide rail.
In process of production, when finding that lens assembly is bad during to the lens assembly place under repair, need earlier focusing ring 100 to be disassembled, because the elastic fastening hook 33 of restriction focusing ring 100 optical axis direction degree of freedom is a resilient material, has stronger toughness, only need 33 groups of cylindrical shells 42 from lens barrel 40 of the elastic fastening hook on the focusing ring 100 just can be taken off focusing ring 100.Be appreciated that driving link 31 and opening 32 on the focusing ring 100 of the present invention are not limited to present embodiment, can also need form a plurality of driven members 41 on the corresponding lens barrel 40 for a plurality of.
The driven member that the driving link of focusing ring of the present invention can effectively drive lens barrel rotates the realization focusing; When camera lens occurs when bad, only need the elastic fastening hook on the focusing ring dialled from lens barrel and just focusing ring can be disassembled easily, can not cause the damage of material and the increase of production cost.
In addition, those skilled in the art also can do other variation in spirit of the present invention, and certainly, the variation that these are done according to spirit of the present invention all should be included within the present invention's scope required for protection.
