Description
Technical field
The invention belongs to take pictures and image into shadow technical field, and in particular to a kind of focus adjustable formula based on pinhole imaging system
Pinhole camera camera lens.
Background technology
The pinhole imaging system of pinhole photography is a kind of former ancient imaging technique, is taken according to " pinhole imaging system " this physical principle
Obtain image.Light arrives at egative film in a linear fashion by pin hole, is not distorted by the glass of camera lens, so foring unique
Imaging characteristic.This lens construction is simple, the depth of field is infinitely great, light-inletting quantity is small, although the time for exposure is longer, simple equipment knot
Structure, simple style of shooting change but with complicated plasticity with the infinite sprawling of imagination.This pinhole photography
The pinhole imaging system form in time immemorial can enter a completely new photography visual field with us.However as the hair at full speed of electronic technology
Exhibition, slr camera, the modern shooting technologies of the convex lens glass forms of digital camera is substantially instead of original ancient intuitive
Imaging technique.There is manufacturer's life in major part manufacturer once in a while without the aperture camera lens for producing original ancient imaging mode at present
Production, expensive, ordinary people can not consume, and function cannot be satisfied high-end personage's demand.
In conclusion the focal length of existing pinhole camera camera lens is fixation, it cannot be satisfied people and needing to shoot difference
The demand that focusing is adjusted when picture, captured effect is unable to reach the requirement of user when capturing picture in this way, claps
Taking the photograph required quality of making, there is always some defects with photographer's requirement.
In the prior art, such as a kind of adjustable pinhole lens that China Patent Publication No. CN207232489U is provided, including
Shell is equipped with internal thread on the madial wall of the shell, is also set vertically on the madial wall of the housing cavity there are two column
The upper end of groove, each cylindrical recesses is connected to by a vertical axis hole with outer, is inserted respectively in two axis holes
Equipped with the first axle body and the second axle body, it is fixed with the first circular slab in the lower end of the first axle body, in the second axle body
Lower end is fixed with the second circular slab, and arranged in a ring first is equipped in the both sides up and down of the edge of first circular slab
Double wedge is equipped with the second double wedge arranged in a ring in the both sides up and down of the edge of second circular slab；In the shell
It is equipped with the first ring body, the second ring body, third ring body and the 4th ring body in inner cavity successively from top to bottom；Above-mentioned technical proposal structure letter
It is single reasonable, focus adjustable, but it is to drive internal double wedge rotation to be debugged using external shaft to debug focal length, such debugging
Mode is complicated, and is not easy to debug during taking pictures.
Invention content
The purpose of the present invention is to provide a kind of focus adjustable formula pinhole camera camera lens based on pinhole imaging system, in solution
State the problem of being proposed in background technology.
To achieve the above object, the present invention provides the following technical solutions：
A kind of focus adjustable formula pinhole camera camera lens based on pinhole imaging system, including：
Camera pedestal, front shroud of finding a view, the camera pedestal are threadedly coupled with front shroud of finding a view, inner round side in the front shroud of finding a view
Equipped with focus adjustment circle, focus adjustment circle outer ring is equipped with the threaded hole for installing connecting pin；
The front shroud outer ring of finding a view is equipped with U-shaped guide groove；
It is equipped with regulation ring on the outside of the front shroud outer circle of finding a view, regulation ring is internally provided with screw slot.
Preferably, the connecting pin passes through U-shaped guide groove, and outside is extend out in screw slot.
Preferably, the camera pedestal and the junction of digital camera and slr camera are fixed.
Compared with prior art, the beneficial effects of the invention are as follows：The present invention is using the structure of pinhole imaging system debugging focal length, solution
The fixed focal length of existing pinhole camera camera lens of having determined cannot be satisfied what people's focusing when shooting different pictures was adjusted
Problem, and the aperture camera lens of original ancient imaging mode have manufacturer's production once in a while, but expensive, and ordinary people can not
Consumption, function cannot be satisfied the demand of high-end personage again；The present invention is not only easy to carry, but also can quickly capture picture.
Description of the drawings
Fig. 1 is exploded view of the present invention；
Fig. 2 is sectional view of the present invention.
In figure：1 camera pedestal, 2 focus adjustment circles, 3 connecting pins, 4 regulation rings, 41 screw slots, 5 find a view front shroud,
51U type guide grooves.
Specific implementation mode
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation describes, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
- 2 are please referred to Fig.1, the present invention provides a kind of technical solution:
A kind of focus adjustable formula pinhole camera camera lens based on pinhole imaging system, including camera pedestal 1, front shroud 5 of finding a view, it is described
Camera pedestal 1 is threadedly coupled with front shroud 5 of finding a view, and inner round side is equipped with focus adjustment circle 2, focus adjustment circle 2 in the front shroud 5 of finding a view
Outer ring is equipped with the threaded hole for installing connecting pin 3；5 outer ring of front shroud of finding a view is equipped with U-shaped guide groove 51；The front shroud of finding a view
Regulation ring 4 is equipped on the outside of 5 outer circles, regulation ring 4 is internally provided with screw slot 41；
The connecting pin 3 passes through U-shaped guide groove 51, and outside is extend out in screw slot 41.The camera pedestal 1 and number
The junction of code camera and slr camera is fixed.
As shown in Figure 1, camera pedestal 1, is fixed to the camera lens junction of camera by the present apparatus first, when adjusting regulation ring 4
When, connecting pin 3 is moved along the direction of screw slot 41, and the U-shaped guide groove being equipped in front shroud 5 of finding a view makes connecting pin
3 intelligence of nail is moved forward and backward, and at this time, focus adjustment circle 2 carries out front and back focus adjustment.The present invention is debugged using pinhole imaging system
The structure of focal length, the fixed focal length for solving existing pinhole camera camera lens cannot be satisfied people and focus when shooting different pictures
The problem of away from being adjusted, and the aperture camera lens of original ancient imaging mode, have manufacturer's production once in a while, but price is high
Expensive, ordinary people can not consume, and function cannot be satisfied the demand of high-end personage again；The present invention is not only easy to carry, but also can
Quickly capture picture.
