Ray spacer

Abstract

The invention discloses a ray spacer. The ray spacer comprises a movable shielding part for shielding a ray outlet of an external ray source, and a power part for driving the shielding part to move to generate sheltering or sheltering removal of rays. The ray spacer further comprises a shielding box body covering the ray outlet and the shielding part. The shielding box body is provided with a light-out groove communicated with the ray outlet. The rays of the external ray source are output through the ray outlet, the shielding part installed on the ray outlet can be driven by the power part to shelter the ray outlet, therefore, output of the rays can be sheltered, when the rays are needed, the power part can drive the shielding part to be moved away from the ray outlet, and therefore the rays are output. Thus, harm of ray radiation to users and other organisms can be reduced, the shielding box body covering the ray outlet and the shielding part further shields the ray radiation, and the rays can be output through the light-out groove.

Description

technical field [0001] The invention relates to the field of ray scanning perspective, in particular to a ray spacer. Background technique [0002] The application range of radiographic scanning is more and more extensive, especially in the field of medical or security inspection. [0003] In the prior art, when the radiation scanning device scans multiple objects in sequence, in the idle time after scanning one object but not scanning the next object, in order to prevent the radiation source from switching between startup and shutdown too frequently Generally, the radiation source cannot be turned off so as to shorten the life of the radiation scanning device, that is, the radiation emitted by the radiation source is always in an emission state. [0004] However, when the ray scanning device is in operation, the ray, especially the X-ray, is likely to radiate the user or other organisms, thereby causing certain damage to the user or the organism or even the detected object...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, when the radiation scanning device scans multiple objects in sequence, in the idle time after scanning one object but not scanning the next object, in order to prevent the radiation source from switching between startup and shutdown too frequently , so as to shorten the life of the ray scanning device, generally the ray source cannot be turned off, that is, the ray emitted by the ray source is always in the emission state

[0004] When the ray scanning device is in operation, the ray, especially the X-ray, is likely to radiate to the user or other organisms, thus causing certain damage to the user or the organism or even the detection item.
