Embodiment
Consult Fig. 2 and Fig. 4 together, the utility model video camera mainly comprises:
The utility model design has the lens cap 330 of dust reduction capability, be fastened between described camera lens 310 and through hole 323 walls, the parcel camera lens 310 and block camera lens 310 and through hole 323 walls between the slit, make dust be difficult for entering in the camera, improve dustproof effect, make the higher optical effect of the permanent maintenance of video camera;
And lens cap 330 has the function that len 310 is avoided the external force damage as the shell of camera lens 310;
In addition, lens cap 330 cylindrical shells are to be fastened between described camera lens 310 and through hole 323 walls, are easy to installation and removal.
For making lens cap 330 better fixing, can adopt following design:
The outer wall of described lens cap 330 cylindrical shells is provided with first stopper section 331 and second stopper section 332 of axial separation.Described first stopper section 331 and second stopper section 332 lay respectively at camera lens shell 320 outer, in, interval between described first stopper section 331 and second stopper section 332 is adaptive with described camera lens shell 320 through holes 323 wall thickness, makes things convenient for lens cap 330 to fix on camera lens shell 320 through holes 323 hole walls.
Described second stopper section 332 is block-like protrusions, and described camera lens shell 320 through holes 323 walls have axial notch 325, and described groove 325 degree of depth are more than or equal to described second stopper section 332 height.Such design is to make things convenient for second stopper section 332 of lens cap 330 to enter in the described camera lens shell 320 from described groove 325, but first stopper section, 331 backstops are in described through hole 323 outer walls.Rotate described lens cap 330, can lens cap 330 is firmly secured between described camera lens 310 and the camera lens shell 320 so that stagger with described groove 325 in second stopper section 332.Otherwise, then can split out lens cap 330, make things convenient for video camera to use.
In preferred embodiment, described first stopper section 331 is bulge loops, and 332 contiguous described first stopper sections, described second stopper section, 331 1 sides are perpendicular wall, and offside is a ramp structure.The existence of bulge loop makes the covering effect in the slit between camera lens 310 and through hole 323 walls better, further reaches airtight state.The structure of second stopper section 332 can make lens cap 330 fixing more firm, installation and removal are better.
In addition, the internal diameter of end, described lens cap 330 cylindrical shell outer end is littler than described camera lens 310 external diameters, can block the light that infrared lamp 370 direct projections come, and makes camera lens 310 avoid ultrared interference.
In application, described video camera comprises retainer plate 340, shell of revolution 350 and base 360.Described camera lens shell 320 is hollow balls, is fixed by two hemispheres 321,322 and forms a spheroid.The bowl type structure that described shell of revolution 350 is a both ends open, described bowl type shell of revolution 350 both ends open diameters respectively greater than with less than described camera lens shell 320 sphere diameters.Described retainer plate 340 is pressed on described shell of revolution 350 and camera lens shell 320 on the described base 360 in regular turn.Rotate in the cavity that said structure can make camera lens shell 320 constitute between shell of revolution 350 and base 360, and then the direction of camera lens 310 is also rotated thereupon, satisfy the demand that various directions are made a video recording and installed.
Install for convenient, described retainer plate 340 is fixed on the described base 360 by the draw-in groove structure.The less end of described shell of revolution 350 openings has a breach 351, makes things convenient for staff to touch camera lens shell 320 and makes its rotation.And rotatable mirror head capsule 320 turns in this breach 351 camera lens 310, thereby camera lens 310 is adjusted to than wide-angle.
Have fixedly a plurality of through holes 324 of infrared lamp 370 around the described lens through hole 323.Described infrared lamp 370 outstanding described through holes 324, and described lens cap 330 be positioned at described infrared lamp 370 and camera lens 310 foremost foremost outside the line.Can prevent better that like this infrared ray from entering camera lens 310 inside and causing interference.The structure of described infrared lamp 370 outstanding described through holes 324 also is beneficial to the heat that infrared lamp 370 is sent and dispels the heat.
The infrared lamp that is different from the prior art video camera can be kept off a part of luminous energy by housing parts, the utility model can be brought into play the whole effects of infrared lamp, by the mode that infrared lamp 370 fluorescent tubes are stretched out camera lens shell 320 shells, make camera lens shell 320 can not block the luminous of infrared lamp 370, can access emergent light scope than wide-angle.
Consult Fig. 3, the utility model comprises lens mount 311 and the machine core board 312 that cooperates camera lens 310 focusing and imaging, and described machine core board 312 is positioned at lens mount 311 bottoms.Connect by screw thread between described camera lens 310 and the described lens mount 311.Intersect prior art, the utility model is not undertaken fastening by screw, but sets up a stage clip 313 between camera lens 310 and machine core board 312.Described stage clip 313 is replaced machine core board 312 and camera lens 310, camera lens 310 can be fastened in the lens mount 311 and can not rock and tilt.The utility model design can utilize lens cap 330 and stage clip 313, readjusts lens focus at the scene to reach best photographic effect or to gather the picture of different distance.Specifically be in debug process, directly to regulate camera lens 310 focal lengths, and stablize camera lens 310, do not need complete machine is taken apart and can easily be realized by camera lens stage clip 313 by the lens cap 330 of outwarding winding.
The above only is embodiment of the present utility model; be not so limit claim of the present utility model; every equivalent structure or equivalent flow process conversion that utilizes the utility model specification and accompanying drawing content to be done; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present utility model.
