[0002] An X-ray source is a device or system used to generate X-ray radiation. It is an indispensable key technological component in many fields, including modern medical imaging, industrial inspection, security checks, and scientific research. Its core function is to convert a certain form of energy (usually electrical energy) into high-frequency electromagnetic waves, i.e., X-rays. Depending on different application requirements and technical approaches, X-ray sources vary in structure, working principle, and performance parameters.

[0003] In existing technologies, the fixing mechanisms of X-ray sources are usually simple in structure and have a single adjustment method, which is particularly inconvenient when making multi-angle, high-precision adjustments.

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0019] Obviously, many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0020] Please see Figure 1-3This utility model provides an X-ray source fixing and adjustment mechanism, including a mounting plate 1. Two symmetrical vertical plates 12 are fixedly connected to the top of the horizontal end of the mounting plate 1, and two symmetrical connecting plates 5 are fixedly connected between the two vertical plates 12. A rotating shaft is rotatably inserted between the two connecting plates 5, and a worm gear 13 is fixedly sleeved on the outer surface of the rotating shaft. Both ends of the rotating shaft are connected to a connecting piece 6, and an adjustment box 2 is connected to the top of the connecting piece 6. A worm gear 4 is rotatably connected between the two vertical plates 12, and one end of the worm gear 4 passes through one of the vertical plates 12. The worm gear 4 is externally connected to a knob 3 at one end outside the vertical plate 12. The worm gear 4 meshes with the outer surface of the vertical plate 12. A micro servo motor 16 is fixedly connected to the bottom of the connector 6. The output shaft of the micro servo motor 16 is fixedly connected to a second rotating shaft 19. A second gear 18 is fixedly sleeved on the outer surface of the second rotating shaft 19. A first rotating shaft 8 is rotatably connected to the bottom of the inner cavity of the connector 6. A first gear 17 is fixedly sleeved on the outer surface of the first rotating shaft 8. The first gear 17 meshes with the second gear 18. A rotating plate 9 is fixedly connected to the top of a rotating shaft 8. Two symmetrical connecting square openings 15 are formed on the outer surface of the rotating plate 9, and two symmetrical threaded connecting pieces 14 are slidably formed inside the rotating plate 9. Each of the two threaded connecting pieces 14 has a threaded hole on its outer surface, and bolts are threaded into the four threaded holes. A threaded connecting plate 11 is bolted to the top of the rotating plate 9, and an X-ray source component 10 is fixedly connected to the top of the threaded connecting plate 11. The entire device can be connected to some horizontal and vertical moving devices via a mounting plate 1, thereby achieving [the desired effect]. Normally, the X-ray source 10 moves horizontally and vertically. After the device is installed, the rotation of the knob 3 drives the worm gear 13 to rotate via the worm 4, thereby using the connector 6 to drive the threaded connecting plate 11 to adjust the vertical rotation angle. At the same time, by turning on the micro servo motor 16, the meshing of the second gear 18 and the first gear 17 allows the X-ray source 10 mounted on the top of the rotating plate 9 to adjust the horizontal rotation angle. Thus, after the device is fixedly installed, it is convenient to make multi-directional and precise adjustments to the irradiation angle of the X-ray source 10.

[0021] To facilitate connection between the device and the existing lifting box moving mechanism and meet the conventional lifting and horizontal movement requirements, the vertical and horizontal ends of the mounting plate 1 are provided with two symmetrical connecting holes, and a gap is provided between the adjusting box 2 and the vertical end of the mounting plate 1.

[0022] Furthermore, in order to facilitate the vertical rotation adjustment of the X-ray source 10 driven by the adjustment box 2, the connecting member 6 is U-shaped, and the worm gear 13 is rotatably disposed inside the U-shaped opening, and the connecting member 6 is rotatably connected to the outside of the two connecting plates 5.

[0023] When the X-ray source 10 is adjusted to rotate horizontally, the rotation of the X-ray source 10 is reduced in speed by the ratio of the number of teeth of the first gear 17 and the second gear 18, which enhances the fineness of the rotation adjustment. The first gear 17 and the second gear 18 are both rotatably connected to the inside of the connecting member 6, and the ratio of the number of teeth of the first gear 17 and the second gear 18 is 6:1.

[0024] Furthermore, in order to facilitate the sliding of the two threaded connecting pieces 14 on the rotating plate 9, thereby connecting the threaded holes with different spacings, and in order to improve the stability of the sliding of the two threaded connecting pieces 14 on the rotating plate 9, the threaded connecting pieces 14 are I-shaped, and T-slots are provided on the opposite sides of the two connecting square openings 15. The two ends of the two threaded connecting pieces 14 are respectively slidably engaged in the interior of the two T-slots.

[0025] To facilitate the threaded connection between the threaded connecting plate 11 and the rotating plate 9, the four threaded holes are slidably disposed inside the two connecting square openings 15, and the bottom ends of the four bolts are in contact with the bottom of the rotating plate 9.

[0026] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the protection scope of the present invention.

[0027] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable way without contradiction. In order to avoid unnecessary repetition, this utility model will not describe the various possible combinations separately.

[0028] Furthermore, various different embodiments of this utility model can be combined in any way, as long as they do not violate the spirit of this utility model, they should also be regarded as the content disclosed by this utility model.
