[0002] The radiation emitted by the radioactive source can damage cells, tissues, and even cell nuclei, causing varying degrees of harm to the human body. When other parts of the body are examined, the patient's gonads will be wrapped with radiation-proof cloth to protect them from radiation damage. Medical staff will lay anti-radiation cloth on the bed, and after the patient lies down, they will roll and fix the anti-radiation cloth to shield the gonads and avoid radiation; The above method increases the labor intensity of medical staff, and each patient is wrapped in the same radiation-proof cloth, which affects the cleanliness. In response to the above problems, we propose an adjustable radiation shielding device for radiology department. Summary of the Invention

[0003] In response to the above problems, the present invention provides an adjustable radiation shielding device for the radiology department, in which a radiation shielding cloth is set to cover the patient to avoid direct exposure to radiation. The displacement and winding part rotates in a displacement manner with the assistance of an auxiliary rotating rail to wind up the radiation shielding cloth and move it to the end of the bed. Through a locking mechanism, the fixed part and the displacement and winding part are connected together, and driven by an external power source, they are rotated to the lower end of the bed for storage.

[0004] The present invention provides an adjustable radiation shielding device for a radiology department, comprising a bed body provided with a radiation shielding mechanism; The radiation protection mechanism includes a fixed part, which is extended to both sides of the bed and is rotatably connected to the bed. The fixed part includes a fixed vertical plate, a rotating shaft, and a fixed roller. The rotating shaft is rotatably connected to the bed. The fixed vertical plate is rotatably arranged at the side end of the bed through the rotating shaft. The fixed roller is fixedly connected to the fixed vertical plate. The side end of the bed is fixed with a block that limits the rotation of the fixed vertical plate.

[0005] The gear mechanism is connected with the gear train of the driven gear and the driven gear is connected with the gear train of the driven gear and the driven gear is connected with the gear train of the driven gear.

[0006] The radiation protection mechanism also includes an auxiliary rotating rail, which is fixed to the lower end of the bed body and extends to its side to be pressed against the displacement and winding part.

[0007] The radiation protection mechanism also includes a locking mechanism, one end of which is arranged on the fixed part, and the other end is arranged on the displacement and winding part. The locking mechanism includes a locking plate and a locking sleeve. The locking sleeve is fixed on the rotating shaft. One end of the locking plate is fixed on the rotating rod, and the other end is movable into the locking sleeve.

[0008] Beneficial effects of the present invention: The present invention provides an adjustable radiation shielding device for radiology: 1. Use anti-radiation cloth to shield the patient's surface to avoid direct exposure to radiation; Second, the external driving mechanism drives the movement of the sliding block and the displacement winding unit, so that the displacement winding unit can move and wind up the radiation cloth, making it convenient for the next patient to lie on the bed; 3. When the displacement winding part moves to the end of the side of the bed, the locking plate is inserted into the locking sleeve, and the external power mechanism can simultaneously drive the fixed part and the displacement winding part to rotate synchronously to the lower end of the bed for storage; Fourth, a rotating plate is provided and fixedly connected to the rotating rod to support the winding roller. When the winding roller rotates to the upper end of the bed for displacement, the winding roller is ensured to be stable and prevented from rotating around the rotating rod.
