Detailed Description

In order to make the aforementioned objects, features and advantages of the present application more comprehensible, embodiments accompanying figures are described in detail below. It is to be understood that the specific embodiments described herein are merely illustrative of the application and are not limiting of the application. It should be further noted that, for the convenience of description, only some of the structures related to the present application are shown in the drawings, not all of the structures. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

Referring to fig. 1 and fig. 2, fig. 1 is a three-dimensional schematic view illustrating a plurality of moving members 30 forming a light shielding window 40 in an embodiment of a light shielding apparatus of the present application, and fig. 2 is a schematic cross-sectional view illustrating a workpiece 1 covering the light shielding window 40 shown in fig. 1.

The shade device includes a plurality of moving members 30 (four shown) and a base assembly (not shown).

Two adjacent moving members 30 of the plurality of moving members 30 are movably connected. The plurality of moving members 30 form a light shielding window 40, and the plurality of moving members 30 are used for shielding light emitted by a light source (not shown) and projecting the light to the workpiece 1 supported on the plurality of moving members 30 through the light shielding window 40. The light can only be emitted through the light shielding window 40 under the shielding of the plurality of moving members 30. The workpiece 1 is carried on a number of moving members 30. The light passing through the light shielding window 40 is projected onto the workpiece 1.

The base assembly movably supports the plurality of moving members 30 such that the positions of the plurality of moving members 30 are adjustable, thereby allowing the size of the window 40 to be variable. The size of the light-shielding window 40 may vary, in particular the aperture of the light-shielding window 40 may vary.

When the device is used, light emitted by the light source is emitted through the light-shielding window 40, and the light is limited within a preset range by the light-shielding window 40 and is projected onto the workpiece 1. The aperture of the light-shielding window 40 becomes larger, and a larger cross-sectional light (beam) can pass through to adapt to a larger-sized workpiece 1. The aperture of the light shielding window 40 becomes smaller, and light rays (light beams) with smaller cross sections can pass through the light shielding window to adapt to workpieces 1 with smaller specifications. The light source may be disposed on the base assembly and received in the light shielding window 40. The workpiece 1 may be a screen, a slide, or an X-ray film.

The light shielding window 40 in the light shielding device can be adjusted by adjusting the mutual positions of the plurality of moving members 30, so that the light shielding device can adapt to workpieces 1 with different specifications.

When the light shading device is used, if a gap exists between the workpiece 1 and the moving member 30 in the light projection direction, light can escape from the gap (radially emitted from the light shading window 40) after being reflected by the workpiece 1, and stray light is formed. In order to eliminate the flare, each of the moving members 30 has a supporting surface 30b extending in a predetermined direction, and the supporting surfaces 30b of the plurality of moving members 30 are provided around the outer circumference of the light-shielding window 40. The support surface 30b of each moving member 30 is adapted to be in abutment with the workpiece 1, i.e. there is no gap between the support surface 30b of each moving member 30 and the workpiece 1. In one embodiment, the surface of the workpiece 1 contacting the light shielding device is a plane, and the supporting surfaces 30b of the plurality of moving members 30 are located on the same plane. In another embodiment, the surface of the workpiece 1 contacting the light shielding device is a curved surface, and the supporting surfaces 30b of the plurality of moving members 30 are located on the same curved surface.

Specifically, the contour surface 30a is a plane, perpendicular to and intersecting the support surface 30 b. The plurality of moving members 30 are arranged along the periphery of the light shielding window 40, in two adjacent moving members 30, the contour surface 30a of one moving member 30 is positioned on one side of the contour surface 30a of the other moving member 30, and the contour surfaces 30a of the plurality of moving members 30 are surrounded to form the light shielding window 40. One of the moving members 30 is slidably engaged with the other moving member 30 in a direction in which the contour surface 30a of the other moving member 30 extends.

During the mutual movement of two adjacent moving members 30, the portions of the contour surface 30a and the supporting surface 30b corresponding to the light shielding window 40 are extended or shortened, so that the aperture of the light shielding window 40 is increased or decreased. The light-shielding window 40 can be changed by controlling the adjacent two moving members 30 to move relative to each other.
