[0030] Specifically, two movable plates 2 are movably connected on both sides of the main lead plate 1 through bearings. The inner cavity of the support box 3 at the bottom of the movable plate 2 is provided with an adjustment component. The inner cavity of the support box 3 at the bottom of the main lead plate 1 has no structure. The top of the lead screw 4 is rotatably connected to the top of the inner cavity of the support box 3 through a bearing, and the bottom end is fixedly connected to a limited position circular block to prevent the threaded sleeve 5 from separating from the lead screw 4. The universal wheel 6 can rotate and slide to facilitate the purpose of adjusting the angle of the movable plate 2 and moving the entire device. The material of the movable plate 2 and the main lead plate 1 is lead, which is the main radiation shielding material due to its high density and excellent radiation absorption capacity.
[0031] The first bevel gear 7 is located at the top of the surface of the screw 4 to prevent it from affecting the movement of the threaded sleeve 5. The protective lead cloth 8 is laid on the front of the main lead plate 1 and the movable plate 2, which can absorb the radiation generated by the imaging department. The lead glass 9 on the top of the inner cavity of the main lead plate 1 can enable medical staff to observe patients and can also prevent radiation. Lead is added to this glass to provide transparency and radiation protection functions, so that medical staff can observe patients or the surgical process. The weighted bevel block 10 can have enough dead weight to ensure the stability of the device. Specific embodiment 2
[0033] See also Figure 1-5 On the basis of the specific embodiment 1, the lifting member includes a rotating rod 11, which is movably connected to the top of one side of the inner cavity of the support box 3, one end of the rotating rod 11 is fixedly connected to the second bevel gear 12, the second bevel gear 12 is engaged with the first bevel gear 7, and the other end of the rotating rod 11 is fixedly connected to the handwheel 13. The front and rear ends of both sides of the main lead plate 1 are fixedly connected to the sealing strip 14, and a gasket 15 is fixedly connected to one side of the support box 3. The bottom of the gasket 15 extends to the bottom of one side of the weighted oblique block 10. An extension groove is opened at the bottom of the inner cavity of the support box 3, and the inner cavity of the extension groove extends to On the outside of the weighted inclined block 10, the surface of the universal wheel 6 is slidably connected to the inner cavity of the extension groove, one side of the surface of the threaded sleeve 5 is fixedly connected to the limiting block 16, a limiting groove is provided on one side of the inner cavity of the support box 3, and one side of the limiting block 16 is slidably connected to the inner cavity of the limiting groove. A circular hole is provided on the top of one side of the inner cavity of the support box 3, and one end of the rotating rod 11 extends to the outside of the support box 3 through the inner cavity of the circular hole. A threaded pin 17 is threadedly connected to one side of the inner cavity of the handwheel 13, a warning sign 18 is fixedly connected to the top of the front side of the main lead plate 1, and a working status screen 19 is fixedly connected to the top of one side of the front side of the main lead plate 1.
[0034] Specifically: one end of the rotating rod 11 is fixedly connected to the second bevel gear 12, and the second bevel gear 12 is meshed with the first bevel gear 7. The other end of the rotating rod 11 extends to the outside of the support box 3 through the circular hole, and the other end is fixedly connected to the handwheel 13. A threaded pin 17 is threadedly connected to one side of the inner cavity of the handwheel 13. The threaded pin 17 can limit the position of the handwheel 13. The sealing strip 14 can ensure that the movable plate 2 and the main lead plate 1 are sealed when the movable plate 2 rotates. The gasket 15 can ensure that the two support boxes 3 are sealed when the support box 3 rotates at a certain angle to prevent radiation exposure and harm to medical staff.
[0035] The extension groove is located at the bottom of the inner cavity of the support box 3, which can facilitate the threaded sleeve 5 to drive the universal wheel 6 to move up and down, so that the gap between the bottom of the device and the ground is reduced. The limit block 16 slides in the inner cavity of the limit groove, which can limit the movement of the threaded sleeve 5. The warning sign 18 can warn unrelated personnel to prevent them from approaching. The working status screen 19 can tell other patients to wait outside to prevent the protective device from being opened, which will cause radiation exposure.
[0036] The working principle of the utility model is as follows: when the radiation protection device is used in the imaging department, the threaded pin 17 is first screwed out and the hand wheel 13 is rotated. The hand wheel 13 drives the rotating rod 11 to rotate, and the rotating rod 11 drives the second bevel gear 12 to rotate. The second bevel gear 12 drives the first bevel gear 7 to rotate, and the first bevel gear 7 drives the lead screw 4 to rotate. The lead screw 4 drives the threaded sleeve 5 to move on its surface, and the lead screw 4 drives the universal wheel 6 to move downward, so that it contacts the ground and separates the weighted inclined block 10 from the ground. Then the movable plate 2 can be pulled to drive the entire device to move, and the movable plate 2 can also be made to rotate around the bearing on one side of the main lead plate 1, so as to adjust the angle of the radiation protection device so that the radiation source is isolated from the outside world. When the adjustment is completed, the hand wheel 13 is rotated in the opposite direction to separate the universal wheel 6 from the ground, so that the weighted inclined block 10 contacts the ground, and the threaded pin 17 is screwed in.
[0037] When the weighted oblique block 10 is brought into contact with the ground, the gap between the bottom of the main lead plate 1 and the movable plate 2 and the ground can be reduced to prevent radiation. When the movable plate 2 is rotated, there will be gaps between the movable plate 2 and the main lead plate 1, as well as between the two support boxes 3 and the two weighted oblique blocks 10 due to the volume of the bearing. The movable plate 2 and the main lead plate 1 are sealed by the sealing strip 14 between the movable plate 2 and the main lead plate 1, and the gasket 15 between the two support boxes 3 and the two weighted oblique blocks 10, thereby achieving the purpose of radiation protection. The lead glass 9 can enable medical staff to observe the specific situation of the patient's X-ray filming. The warning sign 18 and the working status screen 19 can remind irrelevant personnel not to approach, and remind patients waiting in line not to touch the protective device.
