Abstract
The invention discloses a CCD focus adjusting device. The device includes a CCD camera, and is characterized in that the CCD camera includes a shell and a first cambered lens, a spherical lens, a second planar lens and an imaging processing device arranged in the shell in sequence from a light incidence end to a light emergence end, one side on the spherical lens, which is closed to the light incidence end, is provided with an inclined plane, a handle that is beyond an outer surface of the shell is arranged on the spherical lens, a rectangular groove for the handle to pass through is arranged on the shell, and a length direction of the rectangular groove is consistent with a shell direction. By adoption of the abovementioned structure, the distance of the spherical lens relative to the first cambered lens and the second planar lens is adjusted, due to the function of the inclined plane on the spherical lens, a focusing effect of a light source is changed, and the purpose of an adjustable focus is finally achieved.
Description
Technical field
The present invention relates to a kind of CCD focus adjuster, particularly relate to a kind of compact conformation, CCD focus adjuster easy to use.
Background technology
Traditional C CD camera lens assembly is made up of a series of camera lens of having arranged when appearing on the scene, therefore relative focal length is fixing, but in actual use procedure, because may there is the situation needing to finely tune focal length when different occasion uses, traditional CCD camera obviously cannot meet user demand.
Summary of the invention
Problem to be solved by this invention is to provide a kind of CCD focus adjuster, has compact conformation, feature easy to use.
For solving the problems of the technologies described above, technical scheme of the present invention is: a kind of CCD focus adjuster, comprise CCD camera, its innovative point is: described CCD camera comprises shell and arranges the first lens curve be arranged in order from light inputting end to bright dipping end in the housing, spherical lens, second planar lens and imaging processing device, described spherical lens is provided with inclined-plane near light inputting end side, described spherical lens is provided with the handle exceeding outer surface of outer cover, described shell is provided with the rectangular slot passed for described handle, the length trend of described rectangular slot moves towards consistent with shell.
Preferably, the longitudinal section of described handle is trapezoidal, and the face that described rectangular slot contacts with handle is inclined-plane, and described inclined-plane is consistent with handle side gradient.
Preferably, described handle and described rectangular slot transition fit.
Preferably, on described handle, cover has and to be fastened on described handle and engaging locating piece on the housing.
Preferably, described shell longitudinal section ovalize, described spherical lens longitudinal section is the ellipse consistent with described shell longitudinal section.
The invention has the advantages that: by adopting said structure, regulate the distance of relative first lens curve of spherical lens and the second planar lens, due to the ramp effect on spherical lens, thus changing the focusing effect of light source, finally reaching the object of focus adjustable.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
Fig. 1 is the structural representation of a kind of CCD focus adjuster of the present invention.
In figure: 1-shell, 2-first lens curve, 3-spherical lens, 4-second planar lens, 5-imaging processing device, 6-inclined-plane, 7-handle, 8-rectangular slot, 9-locating piece.
Embodiment
CCD focus adjuster of the present invention, comprise CCD camera, CCD camera comprises shell 1 and is arranged on the first lens curve 2, spherical lens 3, second planar lens 4 and the imaging processing device 5 that are arranged in order from light inputting end to bright dipping end in shell 1, spherical lens 3 is provided with inclined-plane 6 near light inputting end side, spherical lens 3 is provided with the handle 7 exceeding shell 1 outside surface, shell 1 is provided with the rectangular slot 8 passed for handle 7, the length trend of rectangular slot 8 moves towards consistent with shell 1.By adopting said structure, regulating the distance of relative first lens curve 2 of spherical lens 3 and the second planar lens 4, because the inclined-plane 6 on spherical lens 3 acts on, thus changing the focusing effect of light source, finally reaching the object of focus adjustable.
The longitudinal section of above-mentioned handle 7 is trapezoidal, and the face that rectangular slot 8 contacts with handle 7 is inclined-plane 6, and inclined-plane 6 is consistent with handle 7 side gradient, handle 7 and rectangular slot 8 transition fit.In order to position the handle 7 after adjustment, on handle 7, cover has and is fastened on handle 7 and the locating piece 9 be fastened on shell 1.In order to be play a good guide effect at adjustment spherical lens 3, shell 1 longitudinal section ovalize, spherical lens 3 longitudinal section is the ellipse consistent with shell 1 longitudinal section.
Finally it should be noted that, above embodiment is only in order to illustrate technical scheme of the present invention and non-limiting technical scheme, those of ordinary skill in the art is to be understood that, those are modified to technical scheme of the present invention or equivalent replacement, and do not depart from aim and the scope of the technical program, all should be encompassed in the middle of right of the present invention.
