Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] The technical solution of this utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments;

[0023] Example:

[0024] The technical solution of the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. Please refer to the accompanying drawings. Figures 1 to 4 Please refer to the following for a radiation-proof door and window airtight protection device provided in this application. Figure 1 , Figure 2 and Figure 3 The system includes a window frame 1; a frame body 3 is installed on one side of the inner wall of the window frame 1; a radiation-resistant glass window 301 is installed inside the frame body 3 via a hinge structure; a sealing strip 302 is provided on the outer ring of the radiation-resistant glass window 301; a metal shielding sealing sheet 303 is installed on the inner side of the sealing strip 302; a first magnetic sealing strip 304 is installed at the outer edge of the metal shielding sealing sheet 303; a second magnetic sealing strip 305 is provided on the outer ring of the first magnetic sealing strip 304; the second magnetic sealing strip 305 is located on the inner wall of the frame body 3; a fixing mechanism is installed inside the frame body 3; and a multi-layer protective mechanism is installed on the side of the radiation-resistant glass window 301.

[0025] Specifically, the frame 3, as a key component supporting the radiation-resistant glass window 301 and other protective components, works in conjunction with the window frame 1 to form a complete door and window frame structure, providing a basic carrier for the realization of subsequent protective functions. The sealing strip 302 is made of high-performance rubber material, possessing good elasticity and aging resistance. The sealing strip 302 can tightly adhere to the contact surface between the radiation-resistant glass window 301 and the frame 3, initially filling the gap between the glass and the frame 3, preventing airflow and the entry of small particles, and reducing the risk of radiation leakage through the gaps. The metal shielding sealing sheet 303 is made of lead alloy and has... Made of metal material with good radiation shielding performance, it can provide secondary shielding against radiation. The first magnetic sealing strip 304 is installed on the edge of the metal shielding sealing sheet 303 and cooperates with the second magnetic sealing strip 305 on the frame 3. When the anti-radiation glass window 301 is closed, the metal shielding sealing sheet 303 is tightly attached to the frame 3 by magnetic force, which further enhances the sealing effect. The fixing mechanism inside the frame 3 can ensure that the anti-radiation glass window 301 is firmly installed. The multi-layer protection mechanism, combined with the anti-radiation performance of the anti-radiation glass window 301 itself, can further improve the blocking ability against various types of radiation.

[0026] Please refer to this carefully. Figure 1 , Figure 2 and Figure 4 The fixing mechanism includes a spring 5 located inside the edge of the frame 3. A pin 501 is installed at the end of the spring 5 away from the frame 3. A fixing groove 102 is provided inside the window frame 1 near the pin 501. The pin 501 moves to be located inside the fixing groove 102.

[0027] Please refer to this carefully. Figure 1 and Figure 4 The pin 501 has a fixing hole 502 inside one end, and a rod 103 is installed on one side of the fixing groove 102. One end of the rod 103 is located inside the fixing hole 502. The pin 501 is composed of a spring and a rod, and the spring is wound around the outside of the rod.

[0028] Specifically, in order to quickly install the frame 3 inside the window frame 1, the worker inserts the frame 3 inside the window frame 1. The pin 501 is compressed by the inner wall of the window frame 1, and the spring 5 deforms. When the pin 501 is located on one side of the fixing groove 102 and is not subjected to compression, the pin 501 will be located inside the fixing groove 102 under the action of the spring 5. The worker operates the pin 501 so that one end of the pin 501 is inside the fixing hole 502, and the frame 3 can be installed inside the window frame 1, which facilitates the operation of the worker.

[0029] Please refer to this carefully. Figure 1 and Figure 3The multi-layer protection mechanism includes lead glass 4 installed on the side of the radiation-resistant glass window 301, an electromagnetic shielding mesh 401 installed on the side of the lead glass 4, and a protective coating 402 installed on the side of the electromagnetic shielding mesh 401 away from the lead glass 4.

[0030] Please refer to this carefully. Figure 1 and Figure 2 A sealing plate 6 is provided at the edge of the side of the frame 3, and the sealing plate 6 is located in the gap between the radiation-resistant glass window 301 and the window frame 1.

[0031] Specifically, in order to improve the radiation protection performance of the anti-radiation glass window 301, the lead glass 4 can effectively block ionizing radiation such as X-rays and gamma rays. The electromagnetic shielding mesh 401 is made of highly conductive copper mesh, which can shield electromagnetic radiation. The protective coating 402 is made of nanomaterials with radiation protection function, which can not only enhance the radiation protection effect, but also improve the transparency and wear resistance of the doors and windows. The sealing plate 6 can prevent some radiation from escaping through the gap between the anti-radiation glass window 301 and the window frame 1, thereby improving the radiation protection performance of the anti-radiation glass window 301.

[0032] Please refer to this carefully. Figure 1 and Figure 2 A storage base 104 is installed on the inner wall of the window frame 1 near the side of the frame 3. A damping rod 2 is rotatably installed inside the storage base 104, and the other end of the damping rod 2 is rotatably connected to the frame 3.

[0033] Please refer to this carefully. Figure 1 and Figure 2 A handle 7 is installed at the bottom of the front of the frame 3 for operating the radiation-resistant glass window 301.

[0034] Specifically, to facilitate operation of the anti-radiation glass window 301, the window frame 1 is connected to the anti-radiation glass window 301 via the storage base 104 and the damping rod 2. The anti-radiation glass window 301 can rotate and open and close around the damping rod 2 as an axis, allowing the door and window to be flexibly opened and closed according to actual needs, meeting daily usage scenarios such as personnel entry and exit and ventilation. When radiation protection is required, the door and window can be quickly closed to ensure protective performance. The damping characteristics of the damping rod 2 make the anti-radiation glass window 301 more stable during opening and closing, avoiding shaking and collisions caused by sudden external impacts or rapid opening and closing. This not only protects the structure of the door and window itself and extends its service life, but also ensures the sealing components and radiation protection. The protective structure is unaffected by severe vibrations, maintaining good airtightness and radiation protection. The handle 7 provides operators with a convenient point of force. Whether opening or closing doors and windows, personnel can operate the radiation-resistant glass window 301 through the handle 7. Compared with directly pushing or pulling other parts of the radiation-resistant glass window 301, it is more labor-saving and precise, greatly improving the convenience and comfort of operation. The window frame 1 and the radiation-resistant glass window 301 are firmly connected by the storage seat 104 and the damping rod 2, ensuring that the relative positions of each protective component remain stable during the opening and closing of doors and windows. They will not be displaced or fall off due to frequent operation, thus ensuring the overall integrity of the protective device and the continuity of its protective performance.

[0035] Please refer to this carefully. Figure 1 and Figure 2 The window frame 1 has multiple sets of guardrails 101 installed inside, and the multiple sets of guardrails 101 are arranged horizontally at equal intervals.

[0036] Specifically, in order to improve the protective performance of the anti-radiation glass window 301, the protective railing 101 can effectively block and prevent the anti-radiation glass window 301 from breaking due to external impact, avoiding glass shards from injuring people indoors. At the same time, it can also protect the internal anti-radiation airtight protective device from direct damage by external forces to a certain extent, ensuring its normal operation. It can also enhance the overall rigidity of the window frame 1. When the door and window are subjected to external forces such as wind force and thermal expansion and contraction, the protective railing 101 can disperse stress, reduce the possibility of deformation of the window frame 1, keep the window frame 1 stable, and help the sealing components to play a better role and maintain the airtightness of the door and window.

[0037] Working principle: The operator inserts the frame 3 into the window frame 1. The latch 501 is compressed by the inner wall of the window frame 1, and the spring 5 deforms. When the latch 501 is located on one side of the fixing groove 102 and is not under pressure, the latch 501 will be located inside the fixing groove 102 under the action of the spring 5. The operator operates the latch 501 so that one end of the latch 501 is inside the fixing hole 502, and the frame 3 can be installed inside the window frame 1. The sealing strip 302 can tightly fit the contact surface between the anti-radiation glass window 301 and the frame 3, which can initially fill the gap between the glass and the frame 3, prevent air flow and the entry of small particles, and reduce the risk of radiation leakage through the gap. The metal shielding sealing sheet 303, which is made of lead alloy, can provide secondary shielding against radiation. The first magnetic sealing strip 304 and the second magnetic sealing strip 305 on the frame 3 cooperate with each other. When the anti-radiation glass window 301 is closed, the magnetic force makes the metal shielding sealing sheet 303 tightly fit the frame 3, further enhancing the sealing effect.

[0038] Finally, it should be noted that the above specific embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although this utility model has been described in detail with reference to the embodiments, those skilled in the art should understand that modifications and equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the claims of this utility model.
