The X-ray emission source and the detector are arranged on the upper and lower sides of the transmission belt, so that the single view angle plane image can be formed. However, with the increase of security demand, the single light source multi-view angle security inspection machine also appears on the market, which can observe the transmission belt of the inspected goods from multiple angles, such as the Chinese invention patent publication No. CN104155697A, which discloses a single ray source multi-view angle three-dimensional display security inspection equipment. Through the multi-beam processing of the ray cone emitted by the single ray source, a plurality of fan-shaped ray beams with different viewing angles are formed. The luggage on the transmission belt is scanned from different angles at the same time, and a plurality of transmission image pairs with different viewing angles are generated once. Combined with image processing algorithm, a plurality of parallax ray image pairs or a left and right eye parallax video pair suitable for human eye observation are formed. With the help of the corresponding three-dimensional display equipment, the observer can see the multiple three-dimensional images of the luggage with different viewing angles or the dynamic rotating three-dimensional video of the luggage, which has a realistic on-site feeling. The scanning of multiple viewing angles improves the precision of the multi-view angle image illegal goods automatic detection function of the equipment, and improves the observation mode and detection precision of the security ray image.

Therefore, how to provide a safety inspection device with multi-view angle imaging and low cost has become a technical problem to be solved in the industry. UTILITY MODEL CONTENT

[0026] Referring to Figures 1 to 3 The utility model safety inspection device embodiment 1, including: box 1;

[0027] Transmission belt assembly 2 in the box 1 is arranged, which is used for transmitting the inspected goods;

[0028] ​A radiation source module is disposed on one side of the transmission belt assembly 2 for emitting rays;

[0029] At least two sets of detector assemblies 4, including multiple detectors arranged at least partially around the transmission belt assembly 2, each set of detector modules being inclined toward the transmission direction of the transmission assembly to receive rays emitted by the radiation source module;

[0030] The collimator 3, located between the radiation source module and the transmission belt assembly 2, includes a focusing cavity 31 and at least two guiding components 33 arranged sequentially, with each guiding component 33 being respectively aligned with the detector assembly 4.

[0031] The focusing cavity 31 is configured as a funnel-shaped first box, and the top of the first box is provided with at least two first gaps 312 respectively corresponding to the guide components 33. The radiation source module is disposed at the bottom of the focusing cavity 31.

[0032] The guiding component 33 includes a second housing 321. The top of the second housing 321 is provided with a second slit 322 for allowing rays to pass through. A mounting bracket 34 is provided inside the second housing 321. Two first shielding plates 323 are arranged in parallel on the mounting bracket 34. A third slit 324 for allowing rays to pass through is formed between the two first shielding plates 323. The mounting bracket 34 is configured to be angularly adjustable and connected to the inside of the second housing 321.

[0033] In operation, the rays emitted from the radiation source module are focused and diverged within the focusing cavity 31 by the first funnel-shaped housing, then exit through the first slit 312, and sequentially pass through the third slit 324 and the second slit 322 for calibration before penetrating and detecting the object under test. This scheme provides multiple detection angles by arranging the detector components 4 into multiple mutually tilted groups. Furthermore, modular assembly is achieved by using the collimator 3 as the focusing cavity 31 and the guide component 33, reducing manufacturing costs. The mounting bracket 34 allows for adjustable angles of the guide component 33, significantly reducing costs while providing convenience in adjusting the angle of the emitted rays, facilitating widespread manufacturing. Further, the mounting bracket 34 is configured in a "U" shape, with its two ends detachably connected to the inside of the second housing 321 via bolts.

[0034] Specifically, the second box body 321 is provided with adjusting screws 325 on both sides, which abut against the mounting frame 34 through the second box body 321, so as to adjust the angle of the mounting frame 34. Further, the adjusting screws 325 are two, which are linearly arranged on both sides of the folding edge respectively, so that the inclination angle of the mounting frame 34 can be adjusted. For example, when the radiation emission angle needs to be adjusted, the screws 341 at both ends of the mounting frame 34 are loosened, and the adjusting screws 325 are twisted, so that the angle of the mounting frame 34 is changed, thereby driving the third gap 324 to change the radiation emission angle.

[0035] The radiation source module and the collimator 3 are arranged below the transmission belt assembly 2, so that the utilization rate of the space in the box body 1 is further improved. Further, the central collimator 3 is perpendicular to the transmission belt assembly 2, and the central collimator 3 comprises a third box body provided with a fourth gap and a second shielding plate fixedly arranged on the third box body. By arranging the central collimator 3, a viewing angle perpendicular to the transmission belt assembly 2 can be provided.

[0036] Further, the top of the second box body 321 is configured to be inclined and perpendicular to the radiation passing through the second gap 322. The shape of the top of the second box body 321 arranged in an inclined manner can regulate the angle of the radiation passing through the second gap 322 and the third gap 324, thereby improving the imaging effect.

[0037] The transmission belt assembly 2 comprises a rotary and closed transmission belt, and the inside of the transmission belt is provided with a third shielding plate, and the third shielding plate is provided with a fourth gap corresponding to the part through which the radiation passes. The arrangement of the third shielding plate and the fourth gap further improves the collimation effect and avoids unnecessary errors caused by radiation scattering in imaging.

[0038] As a further optimization of the present embodiment, the guide assembly 33 is provided with three, and the corresponding gathering cavity 31 is provided with three first gaps 312. In this way, there are three imaging angles, which further improves the imaging quantity, and the multi-angle stereoscopic effect can better distinguish the object to be examined.

[0039] The box body 1 is provided with a closing strip group 5 at both ends to close the transmission belt assembly 2, so as to avoid radiation overflow to harm the human body.

[0040] The above only describes the preferred embodiments of the present application, and it should be pointed out that for ordinary skilled persons in the art, without departing from the principles of the present application, a number of improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present application.
