Background technology
For some CCTV cameras or video camera, owing to can needing respectively to work with evening by day, in order to improve the quality of imaging, conventionally on CCTV camera or camera lens, switching device of optical fiber is installed, the optical filter of two different colours can be switched in CCD module the place ahead, when the sunray on daytime is sufficient, by specialty, filter ultrared smalt and absorb and reflect the infrared ray in available light, thereby allow CCD restore true colour, make picture color more pure and beautiful soft, meet human eye vision, when night is during insufficient light, cutoff filter automatically switches, full spectrum optical glass is started working, make CCD make full use of all light, thereby greatly improved low according to performance.
Existing pair of optical filter technology, normally utilizes the changing method of motor type, and new-type electromagnetic type is switched method.But, utilize electromagnetic type to switch method, for example mode of solenoid valve fork, the shortcoming of slide block displacement when existence is fallen and knocks, meanwhile, existing pair of optical filter technology, have stuck problem, or solved stuck problem but the complicated difficulty of manufacturing of mechanism, quality is wayward.In addition, portioned product is because switch boards is not being located and stop means automatically near two limit positions place, therefore when switch boards stops the extreme position of one end, when shaking or becoming flexible and all may cause switch boards to be offset, cause the optical filter on filter to be subjected to displacement, the camera lens with CCTV camera or video camera that can not be correct aligns, while there is ending the infrared infrared abnormality that sees through on monitor.
Summary of the invention
In order to overcome above-mentioned deficiency of the prior art, the utility model provides a kind of novel pair of optical-filter switcher, its main points by two optical-filter switcher optimal design be summed up as how to design one switch accurately, function-stable, structural reduction, novel pair of optical-filter switcher with low cost, by rational structure of modification, efficiently solve the problems referred to above.
The utility model solves the technical scheme that its technical matters adopts:
A kind of novel pair of optical-filter switcher, it comprises drive unit and by upper casing, the shell that lower casing forms, in described lower casing, be provided with rotating shaft, on it, be set with switch boards, described switch boards upper end is arranged side by side and is useful on the mounting hole that described optical filter is installed, described lower casing locates to be provided with arc raised line under being positioned at described switch boards, described arc raised line and described switch boards motion track adapt, its two ends are provided with limit base, described upper casing, what lower casing was corresponding is also provided with for the mounting groove of described drive unit is installed, described drive unit and described switch boards are in transmission connection.
As the improvement of technique scheme, described switch boards front end is provided with fan-shaped groove, and it is meshing by groove and described drive unit.
As the improvement of technique scheme, its mounting hole edge of described switch boards is provided with the arc notch of being convenient to load and unload described optical filter.
As the improvement of technique scheme, described upper casing and described lower casing corresponding position are provided with arc raised line.
As the improvement of technique scheme, described upper casing comprises lens mount, and described lens mount is provided with for the internal thread of camera lens is installed.
The beneficial effect that the utility model brings has:
Its existence due to arc raised line of novel pair of optical-filter switcher of the present utility model, switch boards is less to the friction of lower casing and other parts when switching action, and switch steadily, even if switching back and forth repeatedly also can not cause wear and aging or the adverse effect to switching precision of switch boards, make it more durable, the design of limit base simultaneously, collocation gear train, when switch boards stays in arbitrary end extreme position, even if shake or become flexible and also can not cause easily the skew of switch boards and the movement of optical filter or dislocation, also make the utility model use more stable, while structural reduction, with low cost.
Accompanying drawing explanation
Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail,
Accompanying drawing 1 is lower cover inner structure schematic diagram of the present utility model;
Accompanying drawing 2 is lower cover external structure schematic diagram of the present utility model;
Accompanying drawing 3 is upper cover inner structure schematic diagram of the present utility model;
Accompanying drawing 4 is upper cover external structure schematic diagram of the present utility model;
Accompanying drawing 5 is switch boards structural representations of the present utility model.
Embodiment
With reference to accompanying drawing 1 to accompanying drawing 5, novel pair of optical-filter switcher of the present utility model, the drive unit, the filter plate carrier switch boards 3 that comprise the shell that formed by upper casing 1, lower casing 2 and install in the inner, be mutually in transmission connection, the interior lower end of lower casing 2 is wherein provided with rotating shaft 21, thereon, the upper end of switch boards 3 is arranged side by side two for the mounting hole 31 of optical filter is installed to switch boards 3 suits simultaneously.
The sector region place that lower casing 2 is positioned under switch boards 3 in the utility model is provided with arc raised line 22, this arc raised line 22 adapts with described switch boards 3 motion tracks, and its two ends are provided with limit base 23, so design makes switch boards 3 less to the friction of lower casing 2 and other parts when switching action, switch steadily, even if switching back and forth repeatedly can not cause its wear and aging or the adverse effect to switching precision yet, and, upper casing 1 is also provided with arc raised line 22 with the corresponding position of lower casing 2, brings into play same effect.Be positioned at the limit base 23 collocation gear trains at arc raised line 22 two ends, when switch boards 3 stays in arbitrary end extreme position, even if be given a shock or slightly become flexible and also can not cause easily the skew of switch boards 3 and the movement of optical filter or dislocation, also make the relative traditional product of this product possess more stable working environment, and then higher-quality shooting effect is provided.
Switch boards 3 its front ends in the utility model are provided with fan-shaped groove 32, its can be by groove 32 a kind of stable intersecting axle drive mechanism of the meshing formation of transmission gear with drive unit, for the automatic switchover of optical filter provides power.In order to load and unload more easily optical filter, mounting hole 31 edges of switch boards 3 arrange arc notch 33.In addition, upper casing 1 also includes lens mount 11, and lens mount 11 is provided with for the internal thread of camera lens is installed.
