[0016] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below in conjunction with the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other. For ease of description, the terms "upper," "lower," "left," and "right" appearing below only indicate that they correspond to the upper, lower, left, and right directions in the accompanying drawings and do not limit the structure.

[0017] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0018] Examples, such as Figure 1 , Figure 2 and Figure 3As shown, this utility model provides a concealed radiation-proof door frame, including an open door frame 1 and a closed door frame 2, which are located on the left and right sides of the doorway. Based on this, the open door frame 1 includes two sets 11 distributed opposite each other on the left side of the doorway. Each set 11 includes a hollow end piece 111. Inside the end piece 111, a C-shaped first lead plate 3 is provided. The side of the first lead plate 4 abuts against the inner wall of the end piece 111. Outside the end piece 111, a side piece 112 is provided. The side piece 112 includes a U-shaped segment 112a with an opening facing the doorway. The U-shaped segment 112a partially overlaps with the end piece 111. A U-shaped second lead plate 4 is provided within the U-shaped segment 112a. The second lead plate 4 and the first lead plate 5... The protective surfaces of the lead profile 3 overlap. The enclosed door frame 2 includes an inner profile 21, which includes a geometric section 211. The middle of the geometric section 211 is connected to the right side of the door opening by screws, and the two sides of the geometric section 211 are provided with wall-pressing sections 212 that bend and extend toward the inner wall of the door opening. A third lead profile 5 is provided between the wall-pressing section 212 and the side of the geometric section 211. An outer profile 22 with the same structure as the side kit 112 is provided on both the front and rear sides of the inner profile 21. A fourth lead profile 6 is provided on the inner side of the outer profile 22. The protective surfaces of the fourth lead profile 6 and the third lead profile 5 are connected to each other.

[0019] Specifically, the two sets 11 of the open door frame 1 are distributed on both sides of the door panel, corresponding to the movable cavity opened in the wall, allowing the door panel to slide back and forth. The end set 111 provided by this utility model has a certain horizontal width, which can extend its span when it matches the door panel. The end set 111 supports the door panel from the side, reducing the door panel from swinging or swaying during the pulling process. The side set 112 serves as decoration and protection on the back side of the door opening, and can also work with the end set 111 to form a high-strength set 11, improving the door frame's resistance to pressure and deformation. The geometric section 211 of the closed door frame 2 provides the final closing distance for the door panel, which is used for sealing and ensuring the stability of the door panel. At the same time, the combination of the inner and outer plates 22 can also achieve high structural strength and good resistance to deformation and pressure. Moreover, the wall-pressing section 212 has a certain degree of metallic elasticity, which can appropriately buffer external forces, thereby improving the safety and stability of the closed outer casing. The first lead plate 3, the second lead plate 4, the third lead plate 5, and the fourth lead plate 6 are shaped to match the end fittings 111, side fittings 112, geometric segments 21, and outer plates 22 used to install them. The first lead plate 3 and the second lead plate 4 are connected on the left side of the door opening, providing a radiation shielding structure for the door frame. They can form a relatively continuous radiation shielding surface with the lead plates inside the door panel. The third lead plate 5 and the fourth lead plate 6 are connected on the right side of the door opening, thus forming a reasonable radiation shielding surface in the door frame on both sides of the door body. This forms a continuous radiation shielding surface with the lead plates in the door body, thereby improving the radiation shielding capability of the medical door.

[0020] To improve the practicality of the end fitting, the end fitting provided by this utility model is F-shaped. The F-shaped opening of the end fitting faces the inner wall of the doorway and is connected by bolts, while the tail end of the end fitting 111 faces away from the doorway. In this way, the end fitting 111 has a certain width, providing a reasonable mating area with the sliding door panel. Corresponding to the F-shaped shape of the end fitting, its inner cavity is also F-shaped, and the first lead plate 3 is stably nested at one end of the F-shaped cavity, basically covering the horizontal width of the end fitting 111. The side of the end fitting 111 with a smaller area, i.e., the front of the F-shape, contacts one end face of the doorway opening, while the side with a larger area contacts one side face of the U-shaped segment, which helps to improve the combined strength of the end fitting 111 and the side fitting 112.

[0021] To improve the structural strength of the side fitting, this invention provides a bent reinforcing section 112b at one end of the U-shaped section 112a that contacts the back of the end fitting, thereby indirectly increasing the thickness of the side fitting and improving the compressive and deformation resistance of the U-shaped section.

[0022] To improve the supporting performance of the wall-pressing section, the wall-pressing section provided by this utility model includes two stepped L-shaped portions 212a and 212b connected end to end. One side of the second L-shaped portion 212b contacts the inner wall of the doorway. The stepped structure formed by the first L-shaped portion 212a and the second L-shaped portion 212b presses against the inner side of the doorway in a relatively free manner. Under the action of external force, it can produce a certain deformation to achieve the purpose of buffering and improve the safety and stability of the enclosed door frame 2.

[0023] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
