[0002] Radiation-proof lead door, also known as radiation-proof lead door, is a door specially used to block or reduce radiation. This door achieves its radiation protection function by using lead material, a metal with high density and radiation absorption ability. It is mainly used in places that require special radiation protection, such as the radiology department of hospitals, nuclear energy research institutes, laboratories, etc. In these places, due to the presence of electromagnetic radiation or nuclear radiation such as X-rays, Y-rays, ultraviolet rays, etc., radiation-proof lead door can effectively prevent radiation leakage and protect personnel from radiation harm.

[0003] A Chinese patent discloses a radiation-proof lead door (authorization announcement number CN218324638U). This patented technology utilizes a movable cover plate so that the guide rail can be directly removed and replaced from above the door frame. At the same time, the door frame can temporarily stabilize the posture of the radiation-proof lead door body to prevent tipping until the guide rail is replaced, effectively improving the efficiency of disassembly and assembly of the guide rail and facilitating maintenance.

[0004] However, most of the existing radiation-proof lead doors are installed and disassembled by bolts, which results in a slow installation and disassembly efficiency. For example, the above-mentioned reference document adopts a bolt installation method. In actual application, it needs to be fixed and locked by bolts during installation and disassembly, which makes it inconvenient to disassemble. Therefore, those skilled in the art provide a radiation-proof lead door to solve the problems raised in the above-mentioned background technology. Utility Model Content
