Detailed Implementation

[0032] The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this utility model will be described below with reference to the accompanying drawings.

[0033] like Figure 1As shown, a portable X-ray machine simulation device for teaching includes a hollow box 1 and a foldable tripod 2. The box 1 has a light source 3 at the top of its inner cavity, a light-transmitting window 4 at the bottom, and a retractable measuring ruler 5. The light source 3 is connected to a power supply 32. A power switch 6 connected to the power supply 32 is located on the outside of the box 2. The window 4 has an adjustment mechanism and a centering structure on its inner side for adjusting the size of the window and marking its center position. The tripod 2 has a fixed structure and a lifting mechanism on its gimbal 20 for holding the box 2 and adjusting its height. The power supply can be a commercially available AC / DC power supply. The power switch 6 in the figure consists of two knobs: a DC switch knob and an AC switch knob. In teaching applications, the box is mounted on a tripod using a fixed structure. The light emitted by the light source simulates X-rays, which are then shone through the window onto the area to be examined. The height of the box is adjusted using a lifting mechanism, and the specific distance can be measured using a measuring ruler. The window is then adjusted to a suitable size using a window adjustment mechanism and a centering structure, and the center of the window is found so that the center of the light is aligned with the area to be irradiated, thus realizing the teaching operation of simulating X-rays.

[0034] In specific embodiments of this utility model, such as Figure 2 and Figure 3 As shown, the window adjustment mechanism includes a left-right adjustment component 7 and a front-back adjustment component 8. The left-right adjustment component 7 is used to adjust the size of the window 4 in the left-right direction, and the front-back adjustment component 8 is used to adjust the size of the window 4 in the front-back direction. The structure of the front-back adjustment component 8 is the same as that of the left-right adjustment component 7, and they are arranged perpendicularly to each other and staggered vertically within the housing 2. The left-right adjustment component 7 includes two parallel support rods 9, which are connected to the inner walls of the two side housings 2 via telescopic shielding components 10. The two ends of the two support rods 9 are slidably engaged with slide rails 11 on the inner walls of the other two side housings 2. The front ends of the two support rods 9 are connected by a bidirectional telescopic rod group, which drives the two support rods 9 to move closer or further apart. The rear ends of the two support rods 9 are connected by a telescopic sleeve. In actual manufacturing, the shielding component can be a machine tool telescopic cover or a telescopic corrugated plate. By adjusting the distance between the support rods, the amount of light blocked by the shielding component is adjusted, thereby adjusting the size of the window. The size of the window is adjusted by a window adjustment mechanism and a shielding component to control the size of the irradiation field and simulate the justification of the radiation dose.

[0035] In the specific production process, such as Figure 3 , 4As shown, the bidirectional telescopic rod assembly includes a sleeve 12 and two screws 13 with opposite directions of rotation. The inner holes on both sides of the sleeve 12 are provided with internal threads with opposite directions of rotation, and the two screws 13 are engaged with the threads on both sides of the sleeve 12. A cylindrical adjusting knob 14 is provided in the middle of the sleeve 12. An opening matching the outer circle of the adjusting knob 14 is provided on the side wall of the housing 2. The outer circle of the adjusting knob 14 can extend to the outside of the opening. The outer circle of the adjusting knob 14 is provided with anti-slip texture. The telescopic rod includes an outer sleeve 15 and an inner sleeve 16. The fixed end of the outer sleeve 15 is fixedly connected to a support rod 9. The free end of the inner sleeve 16 can be inserted into the outer sleeve 15. The fixed end of the inner sleeve 16 is fixedly connected to another support rod 9. The sleeve can be rotated by turning the adjustment knob in both directions. The sleeve drives the two screws to extend and retract relative to the sleeve, which in turn drives the two support rods to move closer or further apart, thereby adjusting the size of the irradiation field. The other end of the support rod then drives the change in the mating length of the outer sleeve and the inner sleeve. Two adjustment knobs 14 for adjusting the front and rear irradiation fields and the left and right irradiation fields are respectively set on two adjacent side walls of the housing 2, and the front and rear irradiation fields and the left and right irradiation fields can be adjusted according to actual needs.

[0036] Further optimize the above structure, such as Figure 4 As shown, the inner hole of the outer sleeve 15 is provided with a limiting groove in the axial direction, and the outer wall of the inner sleeve 16 is provided with a protrusion 17 that cooperates with the limiting groove in the axial direction. With this structure, the relative position of the inner sleeve and the outer sleeve can be maintained during the extension and retraction of the inner sleeve and the outer sleeve, ensuring that the windows are adjusted synchronously on both sides.

[0037] In specific embodiments of this utility model, such as Figure 5 As shown, the centering structure includes two intersecting elastic ropes 18. The two ends of the two elastic ropes 18 are respectively connected to the two ends of the two support rods 9 of the front-to-back adjustment component 8 or the left-to-right adjustment component 7. The intersection of the two elastic ropes 18 is the center of the window 4, which is used to simulate X-ray irradiation so that the X-ray is aligned with the center line and aligned with the target area.

[0038] During specific assembly, such as Figure 1 As shown, the two sides of the box body 2 are connected to the middle of an inverted U-shaped suspension rod 19. The two ends of the U-shaped suspension rod 19 are rotatably connected to the side walls of the box body 2 via damping shafts 22. Circular angle gauges 33, concentric with the damping shafts 22, are provided on the surface of the box body 2 around the damping shafts 22. An indicator 34 is provided on the edge of the end of the U-shaped suspension rod 19 connected to the damping shafts 22. Figure 8As shown; the middle part of the U-shaped boom 19 is connected to the gimbal 20 of the tripod 2 via a fixed structure; the top surface of the housing 2 and the two sides adjacent to the U-shaped boom 19 are each equipped with a spirit level 23. The damping shaft is existing technology and can be purchased externally during manufacturing. During operation, the quasi-reflective properties of the damping shaft allow the housing to remain at the desired angle during rotation, facilitating the simulation of X-ray imaging at different angles and positions. When the housing is vertical, the spirit level on the top surface is used to check the horizontality of the housing window; when the housing is rotated 90°, the spirit level on the side surface is used to check the verticality of the housing window.

[0039] In specific embodiments of this utility model, such as Figure 1 , 6 As shown, the tripod 2 includes a gimbal 20 and three rotatably connected legs 21 at its bottom. Each leg 21 includes multiple telescopic joints, with adjacent telescopic joints engaging via a limiting structure. The lower telescopic joint has a spring 24 and a limiting pin 25 inside. The limiting pin 25 is arranged along its diameter, and one end of its inner side is fixed to the inner cavity of the telescopic joint via the spring 24. The side wall of the telescopic joint has a through hole for the extension and retraction of the limiting pin 25. The lower side wall of the upper telescopic joint has a corresponding positioning hole that engages with the limiting pin 25. Simultaneously, the inner wall of the upper telescopic joint has an inwardly protruding guide ridge, and the outer wall of the lower telescopic joint has an axially oriented limiting groove that engages with the guide ridge. The legs of this structure are adjustable in length, and the tripod is available for external purchase. The legs are extended when in use and folded up for easy carrying when not in use.

[0040] As a preferred structure, such as Figure 1 As shown, the lifting mechanism includes a lifting rod 26, a gear (not shown in the figure), and a hand crank 27. The lifting rod 26 vertically penetrates the gimbal 20 of the tripod 2. The gear is located inside the gimbal 20. The side of the lifting rod 26 has teeth that mesh with the gear. The connecting end of the hand crank 27 is coaxially fixed to the gear via a drive shaft. The hand crank 27 is located on the side of the gimbal 20. A support platform 28 is provided at the top of the lifting rod 26. Fixing structures 29 are provided on the support platform 28 and at the bottom of the lifting rod 26 to accommodate shooting from different positions. The box is mounted on the support platform 28 via the fixing structure 29, facilitating shooting from opposing positions, such as... Figure 10 As shown; the box is installed at the bottom of the lifting rod 26 to facilitate shooting of people in a lying or standing position, such as... Figure 9 As shown. A hand crank drives a gear to rotate, which in turn drives a lifting rod to rise and fall, thereby adjusting the height of the housing; this also simulates the adjustment of the focal length and avoids image magnification distortion.

[0041] In specific embodiments of this utility model, such as Figure 7As shown, the fixing structure 29 includes a G-shaped hook 30 and fastening bolts 31. The top or bottom of the G-shaped hook 30 can be connected to the lifting rod 26 or the support platform 28. The top of the U-shaped rod 19 can be placed in the U-shaped groove of the G-shaped hook 30, and fastening bolts 31 are provided on the side wall of the U-shaped groove for tightening and fixing the U-shaped rod 19 inside the G-shaped hook 30. In use, the U-shaped rod is inserted into the U-shaped groove through the opening of the G-shaped hook, and then the top of the U-shaped rod is tightened and fixed using the fastening bolts.

[0042] The above structure is further optimized by connecting the bottom of the lifting rod 26 to the G-shaped hook, which further improves the flexibility of adjustment and can adapt to the shooting needs of different wounded.

[0043] In the actual production process, the measuring ruler can be purchased from an external box ruler; the tripod can be made of carbon fiber, which has the characteristics of high strength and low density, and can reduce the overall weight of the tripod; the box body and its internal structure can be injection molded from engineering plastics, which is simple to process and suitable for mass production.

[0044] In summary, this invention has the advantages of simple and compact structure, low manufacturing cost, and convenient and quick operation. It can simulate X-ray irradiation and adjust the focal length and irradiation field, facilitating the simulation of X-ray irradiation in standing or supine positions. This invention is low-cost and can be configured with multiple sets for teaching, solving the problem of training multiple people with a single setup and improving training effectiveness. Using this invention for simulation training achieves a seamless transition to real-world training, ultimately achieving the goal of accurate photography, making it suitable for educational applications.

[0045] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
