[0023] This application provides a portable dual-view X-ray inspection device, which effectively solves the problems of fixed components inside the device, large device size, limited use in fixed locations, especially in industrial field inspection, and poor portability and mobility. The frame serves as the main support of the device, the connector is used for data output and connection to the display, and the top detector and transmitter, along with another set of detectors and transmitters on the inner side, are located on different horizontal planes, forming the basis for dual-view inspection and generating inspection images from different perspectives. This enables dual-view X-ray inspection of the internal structure of objects. The structure is simple and can be easily moved and quickly deployed.

[0024] Example

[0025] like Figures 1-4 As shown, the technical solution in this application embodiment effectively solves the technical problems that the components are fixed inside the equipment, the equipment is large in size, and can only be used in fixed locations, especially for industrial field testing, where it cannot be moved quickly with the site, resulting in poor portability and mobility. The overall idea is as follows:

[0026] To address the problems existing in the prior art, this utility model provides a handheld dual-view X-ray inspection device, including a frame 11 and a connector 12. A detector 13 is provided at the top of the frame 11, and an emitter 14 is provided at the top of the frame 11. The emitter 14 includes an X-ray tube and a high-voltage generator inside, ensuring that the X-ray beam accurately covers the inspection area, reducing radiation waste and scattering interference. The detector 13 receives X-rays passing through the object, obtains attenuation information, establishes the correspondence between X-ray intensity and the internal structure of the object, and provides raw data for imaging.

[0027] A tray 15 is fixedly installed inside the frame 11. A swing arm 16 is rotatably installed on the side end of the tray 15. A guide rail slider 17 is provided at the end of the swing arm 16. A drive rod 19 is rotatably installed at the top of the guide rail slider 17. A knob 18 is rotatably installed on the side end of the guide rail slider 17. A detector 13 is also installed at the top of the swing arm 16. A transmitter 14 is installed inside the frame 11. Two sets of detectors 13 and transmitters 14 are installed on different horizontal planes. The two sets of detectors 13 and transmitters 14 inspect the object separately. The data is output to the display through the connector 12. Through algorithm analysis, two sets of inspection images from different perspectives are formed.

[0028] The surface of the drive rod 19 is provided with a sliding block 21. Insert rods 22 are fixedly installed on both sides of the sliding block 21. By rotating the knob 18, the knob 18 rotates at the side end of the guide rail slider 17. The knob 18 and the drive rod 19 are connected by a bevel gear, driving the drive rod 19 to rotate freely between the swing arm 16 and the guide rail slider 17. At the same time, the rotating drive rod 19 exerts a force on the sliding block 21, causing the sliding block 21 to slide upward at the top of the guide rail slider 17. The sliding block 21 drives the insert rods 22 to leave the inside of the insertion hole 25, releasing the fixation of the guide rail slider 17. The guide rail slider 17 drives the swing arm 16 to deflect at the side end of the support plate 15, adjusting the angle between the detector 13 and the transmitter 14.

[0029] The two inner sidewalls of the sliding block 21 are provided with guide strips that mate with the side ends of the guide rail slider 17. As the sliding block 21 slides upward, the inner side of the sliding block 21 mates with the outer side of the guide rail slider 17, and the sliding block 21 slides vertically upward along the side end of the guide rail slider 17.

[0030] The side end of the frame 11 is provided with a groove 23 that mates with the guide rail slider 17. By pushing the guide rail slider 17, the inner side of the guide rail slider 17 mates with the groove 23. The groove 23 and the support plate 15 form a semi-circular structure. The guide rail slider 17 slides along the groove 23, which drives the swing arm 16 to swing at the side end of the support plate 15, adjusting the position of the detector 13 at the top of the swing arm 16 and adjusting the angle of the detector 13.

[0031] A positioning ring 24 is fixedly installed on the side end of the frame 11. The inner side of the positioning ring 24 is provided with a plurality of insertion holes 25 that mate with the insertion rod 22. By rotating the knob 18 in the opposite direction, the knob 18 drives the drive rod 19 to rotate in the opposite direction, generating a downward force on the sliding block 21. The sliding block 21 slides along the outer side of the guide rail slider 17. The sliding block 21 drives the insertion rod 22 to move downward and align with the insertion hole 25, inserting the insertion rod 22 into the inner side of the positioning ring 24, fixing the angle of the guide rail slider 17 and the swing arm 16. At the same time, the thread helix angle of the drive rod 19 and the sliding block 21 is less than the friction angle, and the drive rod 19 stops rotating and locks itself with the sliding block 21.

[0032] A rotating shaft that mates with the support plate 15 is fixedly installed at the side end of the swing arm 16, and a wire harness is provided on the outer side of the swing arm 16.

[0033] Working principle:

[0034] The first step is that the frame 11 serves as the main body of the equipment, the connector 12 is used for data output connection to the display, the top detector 13 and transmitter 14, and another set of detectors 13 and transmitters 14 on the inner side are located on different horizontal planes, forming a dual-view inspection base.

[0035] The two sets of detectors 13 and transmitters 14, located on different horizontal planes, can be started and operated independently. The X-ray tube inside the transmitter 14 emits rays, and the ray beam is precisely controlled by the high-voltage generator to cover the inspection area. After the rays penetrate the object, they are received by the corresponding detector 13. The detector 13 establishes the correspondence between the X-ray intensity and the internal structure of the object based on the ray attenuation information, and generates raw data. In dual-view mode, the two sets collect data separately and transmit it to the display via connector 12. Combined with algorithm analysis, different view inspection images are formed, realizing dual-view X-ray inspection of the internal structure of the object.

[0036] Rotating knob 18 causes the drive rod 19 to rotate between the swing arm 16 and the guide rail slider 17, as knob 18 is connected to the drive rod 19 via a bevel gear. The rotation of knob 18 causes the drive rod 19 to rotate between the swing arm 16 and the guide rail slider 17. The thread on the surface of the drive rod 19 acts on the sliding block 21. Because the helix angle of the threads of the drive rod 19 and the sliding block 21 is less than the friction angle, the two are locked relative to each other under normal conditions. Rotating knob 18 generates driving force, causing the sliding block 21 to slide vertically upward along the side end of the guide rail slider 17. The insertion rod 22 moves upward with the sliding block 21, disengaging from the inner insertion hole 25 of the positioning ring 24, thus releasing the fixation of the guide rail slider 17.

[0037] The second step is to push or pull the guide rail slider 17 after releasing the fixation. Its inner side is connected to the slide groove 23 on the side of the frame 11. The guide rail slider 17 slides along the slide groove 23, which drives the swing arm 16 to deflect around the pivot that is connected to the support plate 15. The position and angle of the detector 13 at the top of the swing arm 16 are adjusted simultaneously to adapt to different inspection needs.

[0038] After the angle is adjusted to the correct position, turn the knob 18 in the opposite direction. The drive rod 19 rotates in the opposite direction, generating a downward force on the sliding block 21. The sliding block 21 slides down along the outside of the guide rail slider 17. The insertion rod 22 moves down and aligns with the corresponding insertion hole 25 on the inside of the positioning ring 24 and is inserted. The angle between the guide rail slider 17 and the swing arm 16 is fixed again. Due to the threaded helix angle characteristic, after the drive rod 19 stops rotating, it locks itself with the sliding block 21, maintaining a stable angle.

[0039] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
