Description
Technical field
The utility model relates to optical instrumentation technical field, specifically a kind of axis light wedge device.
Background technology
In China, the investigation to scene of a crime is varied, wherein carrying out prospecting photograph to scene of a crime is a requisite job, and the collection of light on impact is particularly important in the process of prospecting photograph, if illumination light is too strong, the hot spot that illumination light is formed can cover vestige image, and if illumination light is too dark, vestige image cannot be taken again, so be badly in need of a kind of easy to use, stable performance, can adapt to the regulating device of various light source.
Summary of the invention
In order to solve the problems of the technologies described above, the utility model provides a kind of axis light wedge device.
The utility model solves its technical matters and realizes by the following technical solutions:
A kind of axis light wedge device, comprise holder, described holder cylindrically, the through hole perpendicular to holder axis is provided with in the middle part of described holder, adjustment axle is provided with in described through hole, the lower end of described adjustment axle is fixed with conical gear, the left side of described holder inwall is provided with a prism table, a described prism table internal fixtion has a prism wedge, the outer wall of a prism table is provided with a circular cone tooth, the right side of described holder inwall is provided with No. two prism tables, described No. two prism table internal fixtion have No. two prism wedges, the outer wall of No. two prism tables is provided with No. two circular cone teeth, so a circular cone tooth, No. two circular cone teeth are all corresponding with conical gear to be engaged, before described holder, rear two ends are all provided with annulus locating piece.
Its beneficial effect is: the utility model reasonable in design, low cost of manufacture, is coordinated, adjust the angular through two prism wedges by conical gear with the circular cone tooth on prism table outer wall, thus reaches the object eliminating hot spot.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is perspective view of the present utility model;
Fig. 2 is internal view of the present utility model.
Embodiment
In order to make the purpose of this utility model, technical scheme and beneficial effect clearly, below in conjunction with accompanying drawing, preferred embodiment of the present utility model being described in detail, the utility model is described further, to facilitate the technical staff to understand.
As shown in Figure 1 to Figure 2, a kind of axis light wedge device, comprise holder 1, it is characterized in that: described holder 1 cylindrically, the through hole 1a perpendicular to holder 1 axis is provided with in the middle part of described holder 1, adjustment axle 2 is provided with in described through hole 1a, the lower end of described adjustment axle 2 is fixed with conical gear 3, the left side of described holder 1 inwall is provided with a prism table 5, described prism table 5 internal fixtion has a prism wedge 8, the outer wall of a prism table 5 is provided with a circular cone tooth 5a, the right side of described holder 1 inwall is provided with No. two prism tables 6, described No. two prism table 6 internal fixtion have No. two prism wedges 7, the outer wall of No. two prism tables 6 is provided with No. two circular cone tooth 6a, so a circular cone tooth 5a, No. two circular cone tooth 6a are all corresponding with conical gear 3 to be engaged, before described holder 1, rear two ends are all provided with annulus locating piece 4.
The utility model in use, the light that light source produces enters from one end of holder 1, at this moment adjustment axle 2 is manually being rotated, the conical gear 3 of adjustment axle 2 lower end is rotated, a prism table 5 is driven to rotate with No. two synchronous opposite directions of prism table 6, the light of such light source just creates refraction from a prism wedge 8 through after No. two prism wedges 7, light after refraction reflexes on smooth object through semi-transparent semi-reflecting eyeglass again, at this moment camera just can photograph the axis light vestige image without hot spot, solves the problem that latent image vestige not easily gathers.
What finally illustrate is, above preferred embodiment is only in order to illustrate the technical solution of the utility model and unrestricted, although be described in detail the utility model by above preferred embodiment, but those skilled in the art are to be understood that, various change can be made to it in the form and details, and not depart from the utility model claims limited range.
