Abstract
The utility model relates to an airtight reinforcement zooms fog filter head in succession. The left end of shell passes through flange, the sealed fixed primary mirror section of thick bamboo of first screw, and the right -hand member of shell is through right flange, conductive rubber pad, the sealed fixed back of second screw lid, a primary mirror section of thick bamboo in left end lens group before fixed, there is upper and lower guide way at the middle part of a primary mirror section of thick bamboo, has inlayed respectively in the upper and lower guide way to become times lens group and compensation camera lens group, become times lens group and compensation camera lens component and do not pass through third, fourth fix with screw on a cam section of thick bamboo, a cam section of thick bamboo and roll and coordinate in the outer face of cylinder of a primary mirror section of thick bamboo, the right -hand member of a primary mirror section of thick bamboo through the 5th screw, bayonet socket flange with the shell fixed, fixed rear mirror head group on the bayonet socket flange in the primary mirror section of thick bamboo, the bayonet socket flange has waist type connecting hole, right flange on through the 6th fix with screw camera pedestal, fixed camera on the camera pedestal. Its simple structure, the gas tightness is good.
Description
Technical field
The utility model relates to a kind of camera lens, particularly a kind of airtight reinforcing continuous vari-focus fog penetration lens.
Background technology
Photoelectric turntable observing target, aim at, in tracing process, require that the steady picture rich in detail of continuous vari-focus is without rocking blooming, simultaneously have under mist weather condition again can Penetrating Fog, thus weaken the impact of fog on operating distance and sharpness, but general zoom lens can not be airtight separately, optical axis rocks and can not reach requirement, and electromagnetic compatibility is a difficult problem especially.
Summary of the invention
In order to overcome the shortcoming of prior art, the utility model provides a kind of airtight reinforcing continuous vari-focus fog penetration lens.Its structure is simple, and impermeability is good.
The technical scheme in the invention for solving the technical problem is: the left end of shell is by flange, the fixing body tube of the first screw sealing, and the right-hand member of shell is by right flange, conductive rubber pad, the fixing bonnet of the second screw sealing; The fixing front lens group of left end in described body tube, there is upper and lower gathering sill at the middle part of body tube, zoom lens group and compensating glass head group is embedded with respectively in upper and lower gathering sill, zoom lens group and produced color difference group are fixed on cam canister respectively by the 3rd, the 4th screw, and cam canister rolls with the external cylindrical surface of described body tube and coordinates; The right-hand member of described body tube is fixed by the 5th screw, bayonet socket flange and described shell, and the bayonet socket flange in described body tube fixes rear lens group, and bayonet socket flange has waist type connecting hole; By the 6th screw fixed cameras frame on described right flange, fixed cameras on camera pedestal.
The utility model structure is simple, and impermeability is good.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is the utility model cut-open view;
Fig. 2 is the utility model light path schematic diagram.
Embodiment
As shown in Figure 1, the left end of shell 8 is by the fixing body tube 1 of flange 3, first screw 27 sealing, and the right-hand member of shell 8 is by right flange 15, the fixing bonnet 20 of conductive rubber pad 16, second screw 17 sealing; The fixing front lens group 2 of left end in described body tube 1, there is upper and lower gathering sill 7,26 at the middle part of body tube 1, zoom lens group 6 and compensating glass head group 10 is embedded with respectively in upper and lower gathering sill 7,26, zoom lens group 6 and compensating glass head group 10 are fixed on cam canister 9 respectively by the 3rd, the 4th screw 5,25, and cam canister 9 rolls with the external cylindrical surface of described body tube 1 and coordinates; The right-hand member of described body tube 1 is fixed with described shell 8 by the 5th screw 13, bayonet socket flange 14, and the bayonet socket flange 14 in described body tube 1 fixes rear lens group 12, and bayonet socket flange 14 has waist type connecting hole 24; By the 6th screw 23 fixed cameras frame 22 on described right flange 15, fixed cameras 21 on camera pedestal 22.
The light shaft coaxle of described front lens group 2, zoom lens group 6, compensating glass head group 10 and rear lens group 12.
Fixing Penetrating Fog optical filtering 18 before target surface 19 in described video camera 21.Controlled the switching of optical filtering 18 by video camera 21 photoreceptor signal, thus reach the effect of Penetrating Fog.
As shown in Figure 2, S1-S26 is lens face, and its parameter is:
