[0002] In medical environments, composite shielded doors are multifunctional protective doors designed specifically for radiation protection, infection control, or isolation of special areas. They combine various materials and technologies to meet the combined safety, hygiene, and functionality requirements of hospitals, laboratories, and other places. Their core features are multi-level protection and scene adaptability.

[0003] Existing shielding doors mainly intercept radiation through lead plates installed inside. In the current technology, the shielding door is fixed as a whole after production, and the lead plate inside is sealed inside, making subsequent disassembly difficult. This increases the difficulty of subsequent maintenance of the shielding door and replacement of the lead plate. In addition, the lead plate is made of a single piece, which makes transportation difficult, and if the lead plate cracks, the whole thing needs to be replaced, which is costly.

[0004] Therefore, given the inconvenience of replacing lead plates and the high maintenance difficulty of existing shielding doors, a shielding door that solves the above problems is needed. Utility Model Content

[0031] Example 1: A composite shielding door structure with a radiation-proof lead plate interlayer includes a fixed beam 1, a T-shaped plate 2 fixedly connected to the lower rear end of the fixed beam 1, a door panel 3 provided on the inner side of the fixed beam 1, an installation groove 4 provided on the upper end of the door panel 3, and the lower end of the door panel 3 movably connected to the interior of the installation groove 4. A lead plate assembly is provided inside the door panel 3, and protective plates 7 are provided on both the front and rear sides of the lead plate assembly. Installation plates 5 are provided on both the front and rear sides of the lead plate assembly and the protective plates 7. A first fastener 8 is inserted inside the installation plate 5 on the front side of the lead plate assembly, and the end of the first fastener 8 is threadedly connected to the interior of the installation plate 5 on the rear side of the lead plate assembly. A U-shaped plate 9 is provided on the outer right end of the door panel 3, and a second fastener 10 is inserted on the front side of the U-shaped plate 9. The end of the second fastener 10 is threadedly connected to the interior of the door panel 3. A handle 11 is fixedly connected to the left front end of the door panel 3, and reinforcing plates 12 are fixedly connected to the front and rear sides of both the upper and lower ends of the door panel 3.

[0032] The mounting plate 5 is used to fix the lead plate assembly and the protective plate 7 into a whole, which is convenient for installation inside the door panel 3. The installed mounting plate 5 is inserted into the door panel 3 from the right end of the door panel 3 to complete the installation of the lead plate. The U-shaped plate 9 is installed on the outside of the right end of the door panel 3 by the second fastener 10, thereby sealing the mounting plate 5 and the lead plate inside the door panel 3. The reinforcing plate 12 is used to increase the strength of the door panel 3 and prevent deformation. The door panel 3 moves left and right through the mounting groove 4 and the T-shaped plate 2 to open and close the shielding door.

[0033] Example 2: The lower end of the T-shaped plate 2 has openings 16 on both the front and rear sides. The inner side of the opening 16 is rotatably connected to the first guide wheel 17. The outer wall of the first guide wheel 17 is in close contact with the inner wall of the mounting groove 4 on both the front and rear sides. The upper end of the fixed beam 1 is located on the inner upper side of the mounting groove 4 and is fixedly connected to the fixed rod 18. The outer side of the fixed rod 18 is rotatably connected to the second guide wheel 19. The outer wall of the second guide wheel 19 is in close contact with the upper side of the lower end of the T-shaped plate 2. The front side of the right end of the fixed beam 1 is fixedly connected to the connecting plate 20 and the rear side of the connecting plate 20 is fixedly connected to the baffle 21. The rear end of the baffle 21 passes through the rear side of the fixed beam 1.

[0034] When the second guide wheel 19 moves left and right, it is in close contact with the upper side of the lower end of the T-shaped plate 2. At the same time, when the first guide wheel 17 moves left and right, it is in close contact with the front and rear sides of the mounting groove 4, thereby reducing the frictional resistance of the left and right movement of the door panel 3 and making it easier to push the door panel 3 left and right.

[0035] As one of the optimized structural designs for Example 1, such as Figures 1-6 As shown, the lead plate assembly includes several interconnected protective lead plates 6. The ends of the protective lead plates 6 are provided with splicing strips 13 for splicing. The front side of the protective lead plate 6 is provided with a groove 14, and the inner side of the groove 14 is provided with lead strips 15.

[0036] For assembling the lead plates, the mounting plate 5 on the rear side is laid flat, and one of the protective plates 7 is placed inside the mounting plate 5. Then, the protective lead plate 6 is installed, and the protective lead plate 6 is assembled in a bottom-to-top order. Then, the lead strip 15 is placed in the groove 14, and then another protective plate 7 is placed. Finally, the mounting plate 5 is placed on the outside of the protective lead plate 6 and the protective plate 7, and the two mounting plates 5 are fixed with the first fastener 8, thereby installing the protective lead plate 6 and the protective plate 7 inside the two mounting plates 5. The protective lead plates 6 are connected in a stepped manner by the splicing strip 13, and the lead strip 15 cooperates with the groove 14 to avoid straight gaps that could lead to radiation leakage.

[0037] Working principle: For the assembly of lead plates, the mounting plate 5 on the rear side is laid flat, and one of the protective plates 7 is placed inside the mounting plate 5. Then, the protective lead plate 6 is installed, and the protective lead plate 6 is assembled in the order of bottom to top. Then, the lead strip 15 is placed in the groove 14, and then another protective plate 7 is placed. Finally, the mounting plate 5 is placed on the outside of the protective lead plate 6 and the protective plate 7. The two mounting plates 5 are fixed by the first fastener 8, thereby installing the protective lead plate 6 and the protective plate 7 inside the two mounting plates 5. The mounting plate 5 is installed inside the door panel 3 from the right end. Then, the U-shaped plate 9 is fixed to the right end of the door panel 3 by the second fastener 10, thereby sealing the mounting plate 5 inside the door panel 3. The door panel 3 can move left and right by cooperating with the T-shaped plate 2 through the mounting groove 4. The second guide wheel 19 and the first guide wheel 17 are used to reduce the friction of the door panel 3 moving left and right.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
