[0002] In the medical field, DR (Digital Radiography) equipment is widely used for the diagnosis and examination of various diseases. However, DR equipment generates X-rays and other radiation during operation. If not properly protected, it can cause radiation hazards to operators and the surrounding environment. Therefore, effective radiation shielding screens are necessary for physical shielding. Currently, most radiation shielding screens for DR equipment on the market are fixed structures with fixed installation positions, lacking flexibility and making it difficult to adjust them according to the actual examination scenario and equipment location, causing many inconveniences for medical operations. At the same time, while some movable radiation shielding screens can meet certain mobility needs, their structural design is unreasonable. When folded, they occupy a large area, which not only occupies valuable operating space in a space-constrained examination room but may also affect the normal layout and use of the equipment. In addition, existing radiation shielding screens also have shortcomings in storage methods. After folding, they lack effective fixing and support structures, are prone to spreading or shaking, have poor stability, and are cumbersome to unfold again, increasing the workload of medical staff.

[0003] Therefore, there is an urgent need in this field for a new type of mobile radiation shielding screen for DR equipment that can, while meeting the physical shielding function of radiation protection, achieve the effects of easy movement, small footprint after folding and storage, stable structure, and simple operation, so as to better meet the actual needs of medical examinations.
