Technical Field

[0001] This utility model relates to the field of lead room technology, specifically a movable radiation protection prefabricated lead room. Background Technology

[0002] A lead room is a radiation protection device constructed from high-density lead materials such as lead plates and lead bricks. It is widely used in medical imaging (such as CT rooms and DR rooms), radiotherapy, nuclear industry testing, and scientific research to shield against X-rays, gamma rays, and neutron rays, ensuring the safety of personnel and the environment.

[0003] Most existing lead rooms are single-piece units. Some lead rooms that can be assembled often require welding to connect and fix the various wall panels. Welding makes it inconvenient to disassemble when the room needs to be moved to another location. In addition, the existing modular lead rooms have many steps and are quite troublesome to assemble.

[0028] In use, first fix the guide rod 9 inside the groove, then insert the connecting column 4 into the guide rod 9, and then insert the front wall panel 2 and the side wall panel 3 into the corresponding connecting column 4 to achieve a quick splicing effect. The connecting plate 6 and the connecting groove 7 are both T-shaped structures, which can play a limiting role after connection to prevent the connecting columns 4 at both ends from tilting. Then, insert the polygonal rod 14 into the threaded sleeve 11, and then rotate the polygonal rod 14 to drive the threaded sleeve 11 downward and connect it to the end of the guide rod 9. Then pull out the polygonal rod 14. At this time, the fixing effect of the connecting column 4 is completed, preventing the connecting column 4 from sliding upward and ensuring the stable installation of the connecting column 4 and the wall panel. Then, install the top cover 5, with the flange fitting against the outer wall of the side wall panel 3 to achieve a secondary positioning effect. This completes the overall assembly of the lead room and can be quickly disassembled for easy reassembly and reuse in other locations.

[0029] If you choose not to remove the polygonal rod 14, you can make a mating hole at the bottom of the top cover 5 and insert it into the top of the polygonal rod 14 to pre-limit the top cover 5 in the front and back, so as to ensure the installation of subsequent construction.
