[0045] The front end of the lower side of the T-shaped plate 13 is fixedly connected to a motor 3 15, and the output end of the motor 3 15 is fixedly connected to one end of the front connecting rod 1 16;

[0046] Specifically, radiography is a comprehensive high-tech technology that uses a beam of radiation to project onto a detector array through an object to be tested, and then reproduces the image of the internal structure of the object to be tested on a computer screen through electronic readout and a computer data acquisition and analysis system. Many clinical diseases need to be examined by radiography equipment to achieve the purpose of clear diagnosis and auxiliary diagnosis; when the existing radiography device is used, since the area irradiated by the X-ray is fixed, when the patient only needs to be partially irradiated, if the area irradiated by the X-ray is larger than the area of ​​the patient's part to be irradiated, it may cause cells in non-examination parts to be damaged by the X-rays, and it may also cause potential threats to surrounding personnel;

[0047] Therefore, when the present embodiment is in use, after the position of the X-ray source 32 is determined, according to the area of ​​the patient's part to be irradiated, the motor 4 30 is used to drive the connecting rod 3 22 and the gear 21 on one side to rotate, so that the gear ring 19 can be rotated, so that the multiple connecting rods 3 22 and the gear 21 rotate at the same time, and under the cooperation of the connecting rod 3 22 and the connecting rod 4 23, the multiple enclosures 1 24 are simultaneously close to or away from the axis of the fixed ring 18, and the enclosure 25 and the enclosure 3 26 form relative sliding, that is, the enclosure 1 24, the enclosure 2 25 and the enclosure 3 26 can be moved. , and the third enclosure 26 form an enclosure with an area close to the area to be irradiated, and then the electric push rod 1 20 drives the enclosure 1 24, the second enclosure 25, and the third enclosure 26 to descend, so that the bottoms of the three are in contact with the patient's body. At this time, the X-rays irradiated by the X-ray source 32 will be blocked by the enclosure, thereby preventing the X-rays from irradiating to positions other than the non-examination site, causing the cells in the non-examination site to be damaged by the X-rays, and also avoiding the potential threat of X-rays to the surrounding personnel;

[0048] Since the enclosure 1 24, enclosure 25, and enclosure 3 26 are often in a hospital environment, the air may contain various particles, such as dandruff, bacteria, etc. These particles may adhere to the inner walls of the enclosure 1 24, enclosure 25, and enclosure 3 26. When in use, these particles may fall onto the exposed parts of the patient, posing a risk of infection. In addition, when the bottoms of the enclosure 1 24, enclosure 25, and enclosure 3 26 are in contact with the patient's skin, body fluids may remain on the bottoms of the three, making it easy for subsequent patients to be cross-infected when using them. Therefore, before using the enclosure 1 24, the enclosure 25, and the enclosure 3 26 to enclose the patient's part to be examined, adjust the areas of the three to the maximum. At this time, the edge of the scraper 33 can be just aligned with the inner edge of the enclosure 1 24, the enclosure 25, and the enclosure 3 26, and then spray disinfectant on the scraper 33, and then use the motor 2 10 to drive the threaded cylinder 27 to rotate, and with the cooperation of the threaded rod 31, the slide 38, and the telescopic rod 12, the scraper 33 is lowered. During the descent of the scraper 33, its edge is aligned with the enclosure 1 24, the enclosure 25, and the enclosure 3 The inner side of the enclosure 26 is scraped to absorb and remove the attached particles, so as to achieve the effect of disinfecting the inner side of the enclosure 1 24, the enclosure 25, and the enclosure 3 26, thereby preventing the particles on the inner wall of the enclosure 1 24, the enclosure 25, and the enclosure 3 from falling onto the exposed parts of the patient during use, thereby preventing infection; when the enclosure work is completed, the entire enclosure is driven up again until the bottom of the enclosure 1 24, the enclosure 25, and the enclosure 3 is flush with the upper side of the sponge roller 36, and then the sponge roller 36 is sprayed with disinfectant. At the same time, The motor 5 35 drives the rotating shaft 34 to rotate, so that the sponge roller 36 rotates, so that the sponge roller 36 is evenly stained with disinfectant, and then the motor 3 15 drives the connecting rod 1 16 to rotate, and with the cooperation of the connecting rod 2 17, the sponge roller 36 moves laterally, and the upper end of the sponge roller 36 forms friction with the lower ends of the enclosing plate 1 24, the enclosing plate 25, and the enclosing plate 3 26, so that the body fluids remaining on the lower surfaces of the three can be removed, thereby avoiding the body fluids remaining at the bottom of the three after use, resulting in cross infection when subsequent patients use them, and the recycling effect is better;

[0049] Thus, by utilizing the adjustable self-cleaning enclosure mechanism, according to the area of ​​the patient's body part to be irradiated, with the cooperation of enclosure 1 24, enclosure 25, and enclosure 3 26, an enclosure with an area close to the area to be irradiated can be formed, and then the enclosure can be driven down and contacted with the patient's body. At this time, the X-rays irradiated by the X-ray source 32 will be blocked by the enclosure, thereby preventing the X-rays from irradiating to positions other than the non-examination area, causing the cells in the non-examination area to be damaged by the X-rays, and also avoiding the X-rays from posing a potential threat to the surrounding personnel. In addition, before the enclosure 1 24, enclosure 25, and enclosure 3 26 are used, the scraper 33 can be sprayed with disinfectant and moved. The method of scraping and removing the particles remaining on the inner side of the enclosure 1 24, the enclosure 25, and the enclosure 3 26 can achieve the effect of disinfection, thereby preventing the particles on the inner wall of the enclosure 1 24, the enclosure 25, and the enclosure 3 from falling onto the exposed parts of the patient when the enclosure 1 24, the enclosure 25, and the enclosure 3 are in use, thereby preventing infection. In addition, the method of spraying disinfectant on the sponge roller 36 can be used to form friction with the lower ends of the enclosure 1 24, the enclosure 25, and the enclosure 3, so as to remove the body fluids remaining on the lower surfaces of the three, thereby preventing the body fluids of the patient from remaining at the bottom of the three after use, resulting in cross infection when subsequent patients use them. The recycling effect is better.

[0050] Working principle: When the patient needs to be irradiated with X-rays, the patient lies flat on the examination bed 8, and the motor 6 37 is used to drive the threaded rod 1 4 to rotate, so that the mounting plate 9 can slide left and right on the threaded rod 1 4 and the sliding rod 1 3 to adjust the position of the X-ray source 32 in the left and right directions, and then the motor 1 7 is used to drive the threaded rod 2 6 to rotate, so that the frame 5 on both sides slides back and forth, and the position of the X-ray source 32 in the front and back directions can be adjusted, so that the X-ray source 32 is aligned with the position of the patient to be photographed, and the electric push rod 2 28 can be used to drive the X-ray source 32 to rise and fall to adjust the distance between the X-ray source 32 and the patient's part to be photographed, until the X-ray source 32 is adjusted to a suitable position, and then the shooting work is carried out, and the display screen 2 can obtain an imaging image, thereby improving the flexibility of shooting, making the shooting position more accurate, and thus improving the shooting quality. When the position of the X-ray source 32 is determined, according to the area of ​​the patient's part to be irradiated, By using the motor 4 30 to drive the connecting rod 3 22 and the gear 21 on one side to rotate, the gear ring 19 can be rotated, so that multiple connecting rods 3 22 and gears 21 rotate at the same time, and under the cooperation of the connecting rod 3 22 and the connecting rod 4 23, multiple enclosures 1 24 are simultaneously close to or away from the axis of the fixed ring 18, and the enclosure 25 and the enclosure 3 26 form relative sliding, that is, under the cooperation of the enclosure 1 24, the enclosure 25, and the enclosure 3 26, a fence with an area close to the area to be irradiated is formed, and then the electric push rod 1 20 is used to drive the enclosure 1 24, the enclosure 25, and the enclosure 3 26 to descend, so that the bottoms of the three are in contact with the patient's body. At this time, the X-rays irradiated by the X-ray source 32 will be blocked by the enclosure, thereby avoiding the X-rays from irradiating to positions other than the non-examination site, causing the cells in the non-examination site to be damaged by the X-rays, and also avoiding the X-rays from causing potential threats to the surrounding personnel;Since the enclosure 1 24, enclosure 25, and enclosure 3 26 are often in a hospital environment, the air may contain various particles, such as dandruff, bacteria, etc. These particles may adhere to the inner walls of the enclosure 1 24, enclosure 25, and enclosure 3 26. When in use, these particles may fall onto the exposed parts of the patient, posing a risk of infection. In addition, when the bottoms of the enclosure 1 24, enclosure 25, and enclosure 3 26 are in contact with the patient's skin, body fluids may remain on the bottoms of the three, making it easy for subsequent patients to be cross-infected when using them. Therefore, before using the enclosure 1 24, the enclosure 25, and the enclosure 3 26 to enclose the patient's part to be examined, adjust the areas of the three to the maximum. At this time, the edge of the scraper 33 can be just aligned with the inner edge of the enclosure 1 24, the enclosure 25, and the enclosure 3 26, and then spray disinfectant on the scraper 33, and then use the motor 2 10 to drive the threaded cylinder 27 to rotate, and with the cooperation of the threaded rod 31, the slide 38, and the telescopic rod 12, the scraper 33 is lowered. During the descent of the scraper 33, its edge is aligned with the enclosure 1 24, the enclosure 25, and the enclosure 3 The inner side of the enclosure 26 is scraped to absorb and remove the attached particles, so as to achieve the effect of disinfecting the inner side of the enclosure 1 24, the enclosure 25, and the enclosure 3 26, thereby preventing the particles on the inner wall of the enclosure 1 24, the enclosure 25, and the enclosure 3 from falling onto the exposed parts of the patient during use, thereby preventing infection; when the enclosure work is completed, the entire enclosure is driven up again until the bottom of the enclosure 1 24, the enclosure 25, and the enclosure 3 is flush with the upper side of the sponge roller 36, and then the sponge roller 36 is sprayed with disinfectant. At the same time, The motor 5 35 drives the rotating shaft 34 to rotate, so that the sponge roller 36 rotates, so that the sponge roller 36 is evenly stained with disinfectant, and then the motor 3 15 drives the connecting rod 1 16 to rotate, and with the cooperation of the connecting rod 2 17, the sponge roller 36 moves laterally, and the upper end of the sponge roller 36 forms friction with the lower ends of the enclosing plate 1 24, the enclosing plate 25, and the enclosing plate 3 26, so that the body fluids remaining on the lower surfaces of the three can be removed, thereby avoiding the body fluids remaining at the bottom of the three after use, resulting in cross infection when subsequent patients use them, and the recycling effect is better;Thus, by utilizing the adjustable self-cleaning enclosure mechanism, according to the area of ​​the patient's body part to be irradiated, with the cooperation of enclosure 1 24, enclosure 25, and enclosure 3 26, an enclosure with an area close to the area to be irradiated can be formed, and then the enclosure can be driven down and contacted with the patient's body. At this time, the X-rays irradiated by the X-ray source 32 will be blocked by the enclosure, thereby preventing the X-rays from irradiating to positions other than the non-examination area, causing the cells in the non-examination area to be damaged by the X-rays, and also avoiding the X-rays from posing a potential threat to the surrounding personnel. In addition, before the enclosure 1 24, enclosure 25, and enclosure 3 26 are used, the scraper 33 can be sprayed with disinfectant and moved. The method of scraping and removing the particles remaining on the inner side of the first, second and third panels 26 can achieve the effect of disinfection, thereby preventing the particles on the inner wall of the first, second and third panels 26 from falling onto the exposed parts of the patient when the panels are in use, thereby causing infection. In addition, the method of spraying disinfectant on the sponge roller 36 can also be used to form friction between the sponge roller 36 and the lower ends of the first, second and third panels 26 to remove the body fluids remaining on the lower surfaces of the three panels, thereby preventing the body fluids of the patient from remaining on the bottom of the three panels after use, thereby preventing the subsequent patients from cross-infection when using the three panels, and the recycling effect is better. ;
