Description
Technical field
The utility model relates to the optical devices technologies field, particularly relates to a kind of camera lens that has novel diaphragm.
Background technology
The video camera of Xiao Shouing generally partly is made up of camera, sound transducer, A/D converter, video/audio scrambler, controller, the webserver, external alert, control interface etc. in the market.Camera itself wherein, generally form by its physical arrangement by preceding mirror group, middle diaphragm, back mirror group and ccd sensor, and it is undistorted in order to guarantee the ccd sensor imaging, generally also paste one deck filter coating enters to stop infrared ray in the ccd sensor front, when this kind camera lens is used for video camera, in the time of by day, camera is imaged as colored and undistorted; To time night, this moment, light was less, and middle diaphragm is all opened, but because the existence of filter coating, made the ccd sensor image blur, and this is the weak point of most of video camera.
In order to improve this deficiency, a kind of camera lens that has novel diaphragm appears on the market, with reference to figure 1, its structure of Fig. 2 is: comprise shank 1 ', diaphragm dial 2 ', blade of diaphragm 21 ', fulcrum pin 22 ', guidepost 23 ', packing ring 3 ', described shank 1 ' be a hollow housing, the lateral wall that is positioned at shank be provided with rocking arm groove 11 ', described diaphragm dial 2 ' centre be provided with light hole 26 ', circumference one side be provided with rocking arm 24 ', its periphery be sheathed on shank 1 ' described rocking arm groove 11 ' with rocking arm 24 ' corresponding inside circumference wall on, described blade of diaphragm 21 ' termination establish a fulcrum pin 22 ', interruption establish a guidepost 23 ', blade of diaphragm 21 ' by fulcrum pin 22 ' hinged be located at diaphragm dial 2 ' on, and described diaphragm dial 2 ' edge circumferentially offer three concentric chutes 25 ', guidepost 23 ' an axial end pass chute 25 ', blade of diaphragm 21 ' be provided with and described chute 25 ' corresponding hole, and with guidepost 23 ' axially the other end is connected packing ring 3 ' be located on the described shank 1 ' inside circumference wall of diaphragm dial 2 ' below.When swing diaphragm dial 2 ' 24 ' time of rocking arm, blade of diaphragm 21 ' shift-in or shift out diaphragm dial 2 ' play a part and filter and printing opacity, solved the defective of most of video camera image blur night on the market, but since this structure diaphragm dial, blade of diaphragm, O-ring seal directly and shank shell madial wall have assembly relation, and diaphragm dial oblique cutting can only be gone in the shank housing madial wall comparatively cumbersome and unfavorable dismounting and maintenance in assembling like this when installing.
The utility model content
At the problems referred to above, the utility model provides a kind of simple in structure, easy accessibility, is beneficial to the camera lens of maintenance.
To achieve these goals, the technical scheme that the utility model adopted is: a kind of camera lens that has novel diaphragm, comprise shank and be located at the interior middle diaphragm of shank, diaphragm comprises upper shell in the middle of described, lower house, and be located at upper shell, diaphragm dial and blade of diaphragm in the lower house, described diaphragm dial is located at the lower house top, circumference one side is provided with rocking arm, be provided with in the described lower house and the corresponding groove of its rocking arm, from then on this rocking arm stretches out in the groove, described upper shell below is along circumferentially being laid with at least three blades of diaphragm, and described blade of diaphragm hinge is located on the diaphragm dial and is in transmission connection with the formation of diaphragm dial.
Further improvedly be: the described upper shell back side is provided with a plurality of buckles, and described lower house is provided with buckle slot corresponding with it, and upper shell is buckled in the lower house buckle slot by buckle.
After adopting technique scheme, the beneficial effects of the utility model are: overcome diaphragm part in the known technology directly and shank have the defective of assembly relation, after the diaphragm parts assembled in the middle of this camera lens adopted, in the whole shank of implanting the camera mirror, rational in infrastructure, simple, easy accessibility, be beneficial to maintenance.

Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described.
Extremely shown in Figure 6 as Fig. 3, a kind of camera lens that has novel diaphragm, comprise shank and be located at the interior middle diaphragm of shank, diaphragm comprises upper shell 1 in the middle of described, lower house 2, and be located at upper shell, diaphragm dial 3 and blade of diaphragm 4 in the lower house, described upper shell 1 back side is provided with a plurality of buckles 12, described lower house 2 is provided with buckle slot 22 corresponding with it, upper shell 1 is buckled in lower house 2 buckle slots 22 by buckle 12, on described, also be provided with light hole 11 in the middle of the lower house, described diaphragm dial 3 is located at lower house 2 tops, be provided with last in the middle of the described diaphragm dial 3, the corresponding light hole 11 of lower house, circumference one side is provided with rocking arm 31, be provided with in the described lower house 2 and the corresponding groove 21 of its rocking arm, from then on this rocking arm 31 stretches out in the groove 21, a fulcrum pin 41 is established in blade of diaphragm 4 terminations, a guidepost 42 is established in interruption, blade of diaphragm 4 is located on the diaphragm dial 3 by fulcrum pin 41 hinges, offer three concentric chutes 32 on the described diaphragm dial, guidepost 42 axial ends pass chute 32, be located on the lower house 2, described upper shell 1 is along circumferentially being laid with three pilot holes 13, and matching with described fulcrum pin 41 is covered on the lower house 2 as pivot point.
When swinging the rocking arm 31 of diaphragm dial 3, blade of diaphragm 4 shift-ins or shift out diaphragm dial 3 and play optical filtering and printing opacity, can swing rocking arm 31 by day and drive the light hole 11 middle filter actions that blade of diaphragm 4 enters diaphragm dial 3, at night, can swing rocking arm 31 and drive the light hole 11 that blade of diaphragm 4 withdraws from diaphragm dial 3, inoperative, solved on the market the unsharp defective of video camera imaging at night, and assembly technology simple, convenient, be beneficial to dismounting and maintenance.
The above, it only is the preferred embodiment of the utility model structure, be not that technical scope of the present utility model is imposed any restrictions, so every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model any trickle modification, equivalent variations and modification that above embodiment did.
