A top block 612 is fixedly connected between the end surfaces of the plurality of springs 611. The two top blocks 612 are fixedly connected to the two outermost protection blocks 607, respectively.

[0023] The use steps of the present invention are as follows: when the adjustable radiation protection device for medical imaging is used, the third motor 503 runs and drives the lead screw 504 to rotate, and the rotation of the lead screw 504 can drive the sliding seat 506 to follow and perform lateral displacement, and the displacement of the sliding seat 506 drives the top frame 507, the tooth plate 508, the side block 509 and the slide rail 510 to follow and perform displacement, thereby achieving the purpose of driving the displacement component 3 to follow the displacement. After the top plate 301 is laterally displaced to a suitable position, the first motor 307 runs and drives the first rotating shaft 308 to rotate, and the rotation of the first rotating shaft 308 can drive the mounting seat 306 and the mounting frame 305 to follow and move downward. At this time, as the mounting frame 305 moves downward, the side frame 302, the top plate 301, the side frame 303 and the first inclined block 304 follow and move downward. When the first inclined block 304 moves downward, it will move to the corresponding second inclined block 610 position below. The plurality of second inclined blocks 610 are respectively used in conjunction with the plurality of protective blocks 607. The use of the springs 611 on both sides and the resilience of the springs 611 provide support for the top blocks 612 on both sides, so that the plurality of protective blocks 607 are in a state of being fitted together. A complete radiation protection barrier is formed by the plurality of adjacent fitted protective blocks 607. When the first inclined block 304 moves downward, the first inclined block 304 will move downward from the position between two adjacent second inclined blocks 610. At this time, the first inclined block 304 will contact the inclined surfaces of the two second inclined blocks 610, thereby synchronously pushing the second inclined blocks 610 on both sides to both sides. After the second inclined blocks 610 are completely moved downward and pass over the protective blocks 607, the side frames 303 on both sides will be clamped between the protective blocks 607 on both sides, completing the pushing and displacement of the top plate 301 into place. When the first inclined block 304 moves downward to adjust the position of the protective block 607, refer to Figure 2As shown, the first inclined blocks 304 on both sides are located at the outer side of the bed board 203, and will not be located at the bed board 203 to cause obstruction after moving down. At this time, the state of the protective block 607 is an open state that is pushed open. When the protective block 607 is pushed to move, the protective block 607 can be moved along the fixed rod 605 through the connection of the bearing seat 606. At this time, the fixed rod 605 and the bearing seat 606 are used in coordination to support and limit the displacement of the protective block 607. Now the position of the protective block 607 corresponding to the upper top plate 301 is pushed open, and the medical imaging examination equipment can perform medical imaging examination on the patient's body part at the lower opening position. Since the top plate 301 is located above the protective block 607, the protective block 607 at other positions can be used to examine the patient's body part. The side frame 303 also plays the role of shielding and preventing radiation on other body parts. After the side frame 303 moves down to the position between the protective blocks 607 on both sides, the side frame 303 will also drive the support 311, the fixed shaft 312, the rotating block 313 and the curtain 314 to move down with it. At this time, the curtain 314 stands above the patient's body. When the medical imaging examination equipment is working, the protective blocks 607 cooperate with the curtain 314 to shield other body parts of the patient from the top and both sides. The radiation protection effect for the unexamined body parts of the patient is better. When the top plate 301 moves to a suitable position to perform a medical imaging examination on the patient, as the top plate 301 moves down, the protective block 607 below can be automatically pushed out to form an opening, and medical imaging examination is performed at the opening position, while other positions are effectively protected.

[0024] Embodiment 2: Figure 5 and Figure 6 As shown, the top of the side frame 303 is symmetrically fixedly connected with a support 311, and a fixed shaft 312 is fixedly connected between the supports 311 on both sides. The outer surface of the fixed shaft 312 is equidistantly rotatably connected with a plurality of rotating blocks 313, and the bottom of the plurality of rotating blocks 313 is fixedly connected with a curtain 314. The spacing between the curtains 314 on both sides is smaller than the width of the side frame 303, and the width of the side frame 303 is consistent with the maximum width of the first inclined block 304.

[0025] The use steps of the present invention are as follows: when the first inclined block 304 moves down to its position, the plurality of rotating blocks 313 cooperate with the setting of the connecting curtain 314, and the plurality of curtains 314 can naturally stand vertically downward above the patient's body. The plurality of spliced ​​curtains 314 can rotate freely, and the curtains 314 can effectively fit the surface unevenness of the patient's body to achieve better protection effect.

[0026] Embodiment 3: Figure 11-13 As shown, a slot 608 is provided on the outer surface of one side of the protection block 607 , and a splicing block 609 is fixedly connected to the outer surface of the other side of the protection block 607 , and the slot 608 matches the splicing block 609 in position.

[0027] The use steps of the present invention are as follows: through the matching arrangement of the slots 608 on the two side surfaces of the protective block 607 and the splicing blocks 609, after the splicing blocks 609 are inserted into the slots 608, the splicing blocks 609 can fill the gaps between the splicing blocks 609, so that the radiation protection effect after the multiple protective blocks 607 are spliced ​​is better, and the practicality of the device is effectively improved.

[0028] The effect and working principle of the whole mechanism are as follows: when the adjustable radiation protection device for medical imaging is used, the legs 201 and the cross plate 202 provide support for the bed board 203, and the patient lies flat on the bed board 203 for medical imaging examination. The displacement component 3, the driving component 4, the rotating component 5 and the protective component 6 are used in coordination to complete the medical imaging examination for the patient lying flat on the bed board 203. Figure 1 As shown, a plurality of protective blocks 607 are spliced ​​to form an anti-radiation plate to provide radiation protection for the patient. Before the device is used and the patient lies on the bed board 203, the use position of the device is adjusted to avoid the position so that the area above the bed board 203 is in an empty state, which is convenient for the patient to lie on the bed board 203 for examination. Starting the second motor 403 can drive the second shaft 404 to rotate, and the rotation of the second shaft 404 can drive the second gear 405 to follow the rotation. When the second gear 405 rotates, it can drive the drive shaft 602 to follow the rotation through the meshing connection with the third gear 603. When the drive shaft 602 rotates, the drive shaft 602 is coaxial with the support shaft 501 and the support shaft 501 is rotatably connected to the inner surface of the connecting seat 402. The second motor 40 The drive of 3 can drive the bracket 502, the first mounting plate 601 and the second mounting plate 604 to rotate accordingly. At this time, the second mounting plate 604 can synchronously drive multiple protective blocks 607 to rotate and flip upward through the connection of the fixing rod 605 and the bearing seat 606. At the same time, the bracket 502 can drive the displacement component 3 to flip upward along with the protective block 607 through the connection of the screw rod 504, the sliding seat 506, the top frame 507, the side block 509 and the slide rail 510. After the displacement component 3, the rotating component 5 and the protective component 6 complete the upward displacement, the surface of the bed board 203 is in an unobstructed state. The patient can now lie on the bed board 203 to start the medical imaging examination operation. After confirming that the patient is lying flat, the second motor 403 is started to reset, driving the device back Figure 1The first inclined block 304 is in the working position in the middle, at this time, the first inclined block 304 is located above the plurality of protective blocks 607, and a medical imaging examination device is installed below the top plate 301, and the medical imaging examination is completed on the vertically corresponding body part of the patient by using the device. When the examination starts, the lateral position of the top plate 301 is adjusted by the operation of the third motor 503, and the displacement of the top plate 301 is used to achieve the purpose of adjusting the use position of the medical imaging examination device, so that the examination can be performed on different body parts of the patient. After the third motor 503 is operated, it can drive the lead screw 504 to rotate, and the rotation of the lead screw 504 can drive the sliding seat 506 to follow the lateral displacement. When the sliding seat 506 is displaced, The setting of the limit rod 505 can support and limit the displacement of the sliding seat 506. The displacement of the sliding seat 506 drives the top frame 507, the tooth plate 508, the side block 509 and the slide rail 510 to follow the displacement, so as to achieve the purpose of driving the displacement component 3 to follow the displacement. After the top plate 301 is displaced horizontally to a suitable position, the first motor 307 is started to drive the top plate 301 to move down to a position close to the patient's body for medical imaging examination. After the first motor 307 is running, it can drive the first rotating shaft 308 to follow the rotation. The rotation of the first rotating shaft 308 can drive the first gear 309 to follow the rotation. When the first gear 309 rotates, it can mesh with the tooth plate 508. The mounting seat 306 and the mounting frame 305 are driven to move downward. At this time, as the mounting frame 305 moves downward, the side frame 302, the top plate 301, the side frame 303 and the first inclined block 304 are moved downward. When the mounting seat 306 moves downward, it will drive the slider 310 to move along the slide rail 510. At this time, the displacement of the mounting seat 306 is supported and limited by the cooperation of the slider 310 and the slide rail 510. When the first inclined block 304 moves downward, it will move to the corresponding second inclined block 610 position below. The multiple second inclined blocks 610 are used in conjunction with the multiple protective blocks 607 respectively. The use of the springs 611 on both sides is used to provide the top blocks 612 on both sides with a rebound force. The support makes multiple protection blocks 607 in a mutually fitted state, and a complete radiation protection barrier is formed by multiple adjacent fitted protection blocks 607. When the first inclined block 304 moves down, the first inclined block 304 will move down from the position between two adjacent second inclined blocks 610. At this time, the first inclined block 304 will contact the inclined surfaces of the two second inclined blocks 610, thereby pushing the second inclined blocks 610 on both sides to both sides synchronously. After the second inclined blocks 610 completely move down and pass over the protection blocks 607, the side frames 303 on both sides will be clamped between the protection blocks 607 on both sides, completing the push displacement of the top plate 301. When the first inclined block 304 moves down to adjust the position of the protection block 607, refer to Figure 2As shown, the first inclined blocks 304 on both sides are located at the outer side of the bed board 203, and will not be located at the bed board 203 to cause obstruction after moving down. At this time, the state of the protective block 607 is an open state that is pushed open. When the protective block 607 is pushed to move, the protective block 607 can be moved along the fixed rod 605 through the connection of the bearing seat 606. At this time, the fixed rod 605 and the bearing seat 606 are used in conjunction with each other to support and limit the displacement of the protective block 607. Now the position of the protective block 607 corresponding to the upper top plate 301 is pushed open, and the medical imaging examination equipment can perform medical imaging examinations on the patient's body parts at the lower opening position. Since the top plate 301 is located above the protective block 607, the protective block 607 at other positions can be used. 07 can shield other body parts of the patient from radiation. After the side frame 303 moves down to the position between the protective blocks 607 on both sides, the side frame 303 will also drive the support 311, the fixed shaft 312, the rotating block 313 and the curtain 314 to move down with it. At this time, the curtain 314 stands above the patient's body. When the medical imaging examination equipment is working, the protective blocks 607 cooperate with the curtain 314 to shield other body parts of the patient from the top and both sides. The radiation protection effect for the unexamined body parts of the patient is better. When the top plate 301 moves to a suitable position to perform a medical imaging examination on the patient, as the top plate 301 moves down, the protective block 607 below can automatically push out an opening, and the medical imaging examination is performed at the opening position. The other positions are effectively protected. After completing the medical imaging examination at a single position, the first motor 307 is started to drive the displacement assembly 3 to move up and reset. At this time, the first inclined block 304 and the side frame 303 are moved up to the top of the protection block 607, and the resilience of the spring 611 is used to drive the protection block 607 to reset to a fitted and shielded state. Next, the third motor 503 is started to move the top plate 301 to the next inspection position, and the first motor 307 is started to drive the top plate 301 to move down to continue to perform medical imaging examination on the patient's body parts. There is no need to manually adjust the protection block 607 for the patient's body protection part. It only needs to be adjusted according to the working position of the top plate 301 to automatically push the protection block 607 open. While performing medical imaging examination on the top open position, Other positions achieve effective radiation protection effects, making the use of the radiation protection device more convenient. When the first inclined block 304 moves down to its proper position, the plurality of rotating blocks 313 cooperate with the setting of connecting the blocking curtains 314, and the plurality of blocking curtains 314 can naturally stand vertically downward above the patient's body. The plurality of spliced ​​blocking curtains 314 can rotate freely, and the blocking curtains 314 can effectively fit the surface unevenness of the patient's body to achieve better protection effects. Through the matching setting of the slots 608 on the surfaces of the protective block 607 and the splicing blocks 609 on both sides, the splicing blocks 609 and the protective block 607 are made of the same material and both have radiation shielding effects. After the splicing blocks 609 are inserted into the slots 608, the splicing blocks 609 can fill the gaps between the splicing blocks 609.The radiation protection effect of the multiple protection blocks 607 after splicing is better, which effectively improves the practicality of the device.
