DETAILED DESCRIPTION OF THE INVENTION

[0021] The following embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention.

[0022] Refer to Figures 1 - 4, A radiation protection isolation device for medical imaging, comprising a base 1. A isolation frame 2 is fixedly connected to the top of the base 1. A lead glass 18 is fixedly arranged on the right side wall of the isolation frame 2. A multi-sided isolation transmission device is arranged inside the isolation frame 2. A placement plate 4 is arranged above the isolation frame 2. The multi-sided isolation device includes a first isolation plate 14 and a second isolation plate 17. The placement plate 4 is provided with a first opening. The isolation frame 2 is provided with a second opening. A track 16 is fixedly connected to the top of the isolation frame 2. The first isolation plate 14 is slidably connected to the inner side wall of the track 16. The first isolation plate 14 slidably penetrates through the top of the isolation frame 2. The second isolation plate 17 is arranged on the right side of the isolation frame 2. The second isolation plate 17 slidably penetrates through the right side wall of the isolation plate 2. The multi-sided isolation transmission device includes a bearing seat 5. The bearing seat 5 is fixedly connected to the top of the placement plate 4. A first rotating rod 6 is fixedly connected to the inner ring of the bearing seat 5. A first pulley 7 is fixedly sleeved on the outer side of the first rotating rod 6. A gear 28 is fixedly connected to the outer side wall of the first rotating rod 6. A motor 9 is fixedly connected to the top of the placement plate 4. A second rotating rod 10 is fixedly connected to the driving end of the motor 9. A second pulley 11 is fixedly sleeved on the outer side of the second rotating rod 10. The second pulley 11 is connected to the first pulley 7 through a belt 8. A rope winding drum 12 is fixedly connected to the outer side wall of the second rotating rod 10. A connection frame 15 is fixedly connected to the top of the first isolation plate 14. A rope 13 is fixedly connected and wound around the outer side wall of the rope winding drum 12. The end of the rope 13 is fixedly connected to the inner side wall of the connection frame 15. A sliding plate 26 is slidably connected to the top of the placement plate 4. A plurality of convex teeth 27 are fixedly connected to the top of the sliding plate 26. The gear 28 meshes with the convex teeth 27. A transmission rod 29 passing through the first opening and the second opening is fixedly connected to the bottom of the sliding plate 26. The bottom of the transmission rod 29 is fixedly connected to the top of the second isolation plate 17. The motor 9 is located on the left side of the bearing seat 5. The plurality of convex teeth 27 are uniformly arranged on the top of the sliding plate 26. This device mainly isolates by placing the radiotherapy equipment inside the isolation frame 2. The lead glass 18 is used for the window of the medical imaging equipment, providing visibility while preventing radiation leakage, and can also be used as the inspection output port of the medical equipment. The equipment can be radiologically isolated in all directions through the isolation frame 2, the first isolation plate 14 and the second isolation plate 17. And personnel can remotely control the motor 9 through the motor, thereby reducing radiation. Specifically, the motor 9 is used to rotate the second rotating rod 10. The second rotating rod 10 drives the first pulley 7 and the first rotating rod 6 to rotate through the second pulley 11 and the belt 8. When the first rotating rod 6 rotates, it drives the sliding plate 26 to slide through the gear 28 and the convex teeth 27. When the second rotating rod 10 rotates, the wound rope 13 will be extended through the rope winding drum 12. In this way, due to gravity, the first isolation plate 14 will move vertically downward along the track 16. And at this time, the sliding plate 26 will drive the second isolation plate 17 to move horizontally to the left through the transmission rod 29. When the bottom of the first isolation plate 14 touches the bottom plate 1, the second isolation plate 17 will also strengthen the isolation of the inner top of the isolation frame 2 by one more layer. In this way, the equipment radiation can be isolated in all directions. When the equipment is not in use,The personnel can also remotely reverse-rotate the motor 9 to open the first isolation plate 14 and the second isolation plate 17 (the method of remotely operating the motor 9 is a prior art (such as infrared rays to control the switch), and will not be described in detail here).

[0023] Auxiliary structures are symmetrically arranged on the outer side wall of the isolation frame 2. The auxiliary structures include a connecting rod 19 and a fixing block 21. The connecting rod 19 is rotatably connected to the outer side wall of the isolation frame 2, the fixing block 21 is fixedly connected to the outer side wall of the isolation frame 2, a spring 22 is fixedly connected to the bottom of the fixing block 21, the bottom of the spring 22 is fixedly connected to the top of the connecting rod 19, a handle 20 is fixedly connected to the inner side wall of the connecting rod 19, a push rod 23 is rotatably connected to the bottom of the connecting rod 19, the bottom of the push rod 23 slidably penetrates through the base 1, a pressing block 24 is fixedly connected to the bottom of the push rod 23, a plurality of universal wheels 25 are fixedly connected to the bottom of the base 1, a plurality of support rods 3 are fixedly connected to the top of the isolation frame 2, the tops of the plurality of support rods 3 are all fixedly connected to the bottom of the placement plate 4, the pressing block 24 is made of rubber material, the fixing block 21 is located directly above the connecting rod 19, the plurality of universal wheels 25 are evenly arranged at the four corners of the bottom of the base 1, the plurality of support rods 3 are evenly arranged on the top of the isolation frame 2, both the isolation frame 2 and the base 1 are made of tungsten material, both the first isolation plate 14 and the second isolation plate 17 are made of lead material. Lead is a very effective radiation shielding material and is usually used to make radiation-proof walls, windows, screens, etc. Lead can effectively absorb X-rays and gamma rays. Tungsten is a high-density material and can also be used for radiation protection with very good radiation protection performance. The personnel can change the position of the device through the handle 20 and the universal wheels 25. After the position is moved, when the personnel release the handle 20, the connecting rod 19 will rotate downward due to the elastic force of the spring 22, so that the push rod 23 will move vertically downward and stop when the pressing block 24 contacts the ground (the default state of the spring 22 is a compressed state and will always apply a downward elastic force), and rubber can increase the friction with the ground, so as to ensure that the device will not shake randomly when the device is in a certain position.

[0024] The working principle of the present invention is as follows:

[0025] The rotating rod two 10 is rotated by the motor 9. The rotating rod two 10 drives the pulley one 7 and the rotating rod one 6 to rotate through the pulley two 11 and the belt 8. When the rotating rod one 6 rotates, it drives the sliding plate 26 to slide through the gear 28 and the convex teeth 27. When the rotating rod two 10 rotates, the wound rope 13 is extended through the winding drum 12. In this way, due to gravity, the partition board one 14 moves vertically downward along the track 16. At this time, the sliding plate 26 drives the partition board two 17 to move horizontally to the left through the transmission rod 29. When the bottom of the partition board one 14 touches the bottom plate 1, the partition board two 17 will further strengthen the isolation of the inner top of the isolation frame 2. In this way, the radiation of the equipment can be isolated in all directions. When the equipment is not in use, the personnel can also remotely rotate the motor 9 in the reverse direction to open the partition board one 14 and the partition board two 17;

[0026] The position of the device is changed through the handle 20 and the universal wheel 25. After the position is moved, the personnel release the handle 20, and the connecting rod 19 rotates downward due to the elastic force of the spring 22. In this way, the push rod 23 moves vertically downward and stops when the pressing block 24 touches the ground.

[0027] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
