It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
As an embodiment of the radiation-proof anti-interference device of the X-ray machine, as shown in fig. 1 to 5, the radiation-proof anti-interference device of the X-ray machine comprises an X-ray machine 1, wherein a front shielding curtain 12 is arranged at the front side of a protecting cover 11 of the X-ray machine 1, a rear shielding curtain 13 is arranged at the rear side of the protecting cover 11, a first extension protecting cover 2 is further arranged at an inlet of the front end of the protecting cover 11 of the X-ray machine 1, a third shielding curtain 3 is further arranged at an inlet of the first extension protecting cover 2, and the third shielding curtain 3 is used for shielding rays emitted to the outside of the X-ray machine 1 when the front shielding curtain 12 is pushed open by luggage; the department still is equipped with second extension safety cover 4 in 11 rear end exits of safety cover of X-ray machine 1, the exit of second extension safety cover 4 still is equipped with fourth shielding curtain 5, fourth shielding curtain 5 is used for shielding the outside ray of directive X-ray machine 1 when rear shielding curtain 13 is backed up by luggage.
The anti-radiation anti-interference device of the X-ray machine is characterized in that a front shielding curtain 12 is arranged on the front side of the X-ray machine 1, a rear shielding curtain 13 is arranged on the rear side of the X-ray machine 1, and can play a basic shielding role, a first extension protective cover 2 and a third shielding curtain 3 are arranged at the front end of a protective cover 11 of the X-ray machine 1, and the third shielding curtain 3 is used for shielding rays emitted to the outside of the X-ray machine 1 when the front shielding curtain 12 is pushed open by luggage; the rear end of the X-ray machine 1 is provided with a second extension protective cover 4 and a fourth shielding curtain 5, the fourth shielding curtain 5 is used for shielding rays emitted to the outside of the X-ray machine 1 when the rear shielding curtain 13 is pushed open by luggage, and the X-rays exposed out of the X-ray machine 1 can be greatly reduced by adopting a double-layer shielding scheme, so that the interference of the X-ray machine on a peripheral nuclear radiation detector is reduced, and the probability of false alarm is reduced. Finally, the purposes of radiation protection and interference resistance are achieved.
The utility model discloses in, when carrying out technological transformation to current X-ray machine, first extension safety cover, second extension safety cover and X-ray machine's safety cover concatenation together can, when making brand-new product, the safety cover of preferred first extension safety cover, second extension safety cover and X-ray machine is integrated into one piece, and part is small in quantity like this, and the equipment is simple.
In the present invention, the distance between the third shielding curtain and the front shielding curtain is at least 60 CM; the distance between the fourth shielding curtain and the rear shielding curtain is at least 60 CM. Although the size of common luggage is not fixed, the size of luggage is limited by common vehicles, a trolley case with the size of 22 inches or less is the most common size, 60CM corresponds to the length of the trolley case with the size of 24 inches or more, and the size of luggage with the size of more than 24 inches is too large, which is rare.

When the front shielding curtain 12 is lifted, the blocked objects can easily pass through the front shielding curtain 12. After the first pull rod 61 is released, the first spring drives the first pull rod 61 and the first transverse rod 62 to return, and the front shielding curtain 12 falls to the normal position. Because the outside end of first pull rod 61 stretches out first extension safety cover 2, people can operate in the equipment outside, and very convenient, and eliminated the potential safety hazard.
In this embodiment, the apparatus further includes a rear curtain lift mechanism 7, the rear curtain lift mechanism 7 includes a second pull rod 71, a second cross rod 72, a second guide sleeve 73, and a second spring 74, the second guide sleeve 73 is fixed at the top of the inner side of the second extension protective cover 4, the second pull rod 71 is arranged in the second guide sleeve 73 in a sliding manner, the outer side end of the second pull rod 71 extends out of the second extension protective cover 4, the second transverse rod 72 is arranged at the inner side end of the second pull rod 71, the second spring 74 is sleeved on the second pull rod 71, two ends of the second spring respectively prop against the second guide sleeve 73 and the second transverse rod 72, for the return of the second pull rod 71 and the second transverse rod 72, the second transverse rod 72 is located inside the top of the rear screen 13, the second transverse rod 72 drives the rear shielding curtain 13 to lift up by pulling the second pull rod 71 outwards to drive the second transverse rod 72 to move outwards. After the rear shielding curtain 13 is lifted, the blocked objects can easily pass through the rear shielding curtain 13. After the second pull rod 71 is released, the second spring drives the second pull rod 71 and the second transverse rod 72 to return, and the rear shielding curtain 13 falls to the normal position. Because the outer side end of the second pull rod 71 extends out of the second extension protective cover 4, people can operate outside the equipment, the operation is very convenient, and potential safety hazards are eliminated.
The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
