Description

Technical Field

[0001] This utility model belongs to the field of radiation protection door technology, specifically relating to a concealed protection device. Background Technology

[0002] X-ray shielding doors are crucial in modern medical equipment rooms and other important entrances. They provide radiation protection, shielding against high-radiation facilities and protecting surrounding people from radiation exposure. Lead is the primary material used in their construction, and these doors are often referred to as lead doors. The shielding material is high-purity lead sheet, and the bonding process is extremely rigorous, resulting in doors that are radiation-free, easy to use, aesthetically pleasing, and offer excellent protection. Lead doors are mainly used at entrances and exits where radiation needs to be blocked, primarily in hospitals, machine rooms, and mining areas, including CT rooms, X-ray rooms, operating rooms, and flaw detection rooms in hospitals.

[0003] Radiation shielding doors mainly consist of a door leaf and a door frame. To facilitate opening and closing, the bottom of the door leaf is often suspended, creating a large gap between it and the bottom of the door frame. Radiation can easily leak out through this gap. Furthermore, as the door frame wears down with use, the gap between the frame and the door leaf widens, increasing the risk of radiation leakage. Existing technologies, such as the radiation shielding door disclosed in patent application number 2022228721398, utilize airbags for sealing and blocking radiation leakage. However, its structure is complex, installation, disassembly, and repair are inconvenient, and the cost is high. Moreover, X-rays are high-energy electromagnetic waves with penetrating power, making the shielding effect of airbags weak, and the problem of radiation leakage still exists. Utility Model Content

[0004] To address the aforementioned issues, this invention proposes a concealed protective device. This device has a simple structure and is easy to install, disassemble, and maintain. It can be concealed within a door. When the door is closed, the device, through a lead plate, aluminum profile, and rubber strip, can block and shield radiation, preventing radiation leakage and improving human safety.

[0005] The technical solution of this utility model is as follows: A concealed protective device includes a shell, an elastic connecting component, a rubber strip, an aluminum profile, and a lead plate; the shell is set in a groove at the bottom of the door leaf, and a reserved hole is provided on the side wall of the door leaf, the reserved hole communicating with the groove, and a spring post on the elastic connecting component is set in the reserved hole; the elastic connecting component is set in the shell, the aluminum profile is connected below the elastic connecting component, a lead plate is set inside the aluminum profile, a rubber strip is set outside the aluminum profile, the elastic connecting component is connected to the shell, and the shell is connected to the door leaf.

[0006] This utility model provides a concealed protective device that can be hidden inside a door. When the door is closed, a spring is squeezed, which in turn squeezes an elastic connecting component. The elastic connecting component, under external force, generates elasticity, causing the aluminum profile to move from inside the housing towards the bottom of the door frame until the rubber strip abuts against the bottom of the door frame. At this point, the rubber strip and lead plate seal the gap between the door and the door frame, effectively blocking rays and shielding radiation. When the door is opened, the spring is no longer squeezed, so the force squeezing the elastic connecting component disappears, and the elastic connecting component returns to its original state. The elastic connecting component then retracts the aluminum profile, rubber strip, and lead plate back into the housing.

[0007] Preferably, the elastic connecting component includes a spring post, a spring plate, and a fixing clip. The spring post connects to the fixing clip. Fixing protrusions are correspondingly provided on both side walls of the housing. The tops of the fixing protrusions contact the fixing clip. The spring post is positioned above the fixing protrusions. The width of the spring plate is less than the gap between the two fixing protrusions. The spring post connects to the fixing clip, and the fixing clip connects to one end of the spring plate. The other end of the spring plate passes through the gap between the two fixing protrusions and the lap bridge on the aluminum profile, connecting to another fixing clip. This other fixing clip connects to the aluminum profile via the spring plate and is connected to the housing. Through the dual action of the fixing protrusions and the connection between the other fixing clip and the housing, there is... The system facilitates stable and flexible connection components. Through the connection between another fixing clip and the aluminum profile, the aluminum profile is effectively controlled. When the door is closed, the door frame squeezes the spring post, which moves towards the spring plate. This, in turn, moves the fixing clip, causing the spring plate to be squeezed and generating elastic force. This force causes the aluminum profile, lead plate, and rubber strip to move downwards (away from the housing). When the door is opened, the door frame no longer squeezes the spring post, the fixing clip returns to its original position, and the spring plate returns to its original state. The spring plates at both ends of the fixing clip effectively raise the aluminum profile, lead plate, and rubber strip, restoring them to their original state.

[0008] More preferably, the width of the bottom of the fixing clip is greater than the gap between the fixing protrusions on the two side walls of the housing, and the width of the top of the aluminum profile is greater than the gap between the fixing protrusions on the two side walls of the housing; the top of the adhesive strip is higher than the top of the aluminum profile; this prevents the fixing clip from moving below the fixing protrusions, which would hinder the movement of the elastic connecting parts, and prevents the aluminum profile from moving between the two fixing protrusions and getting stuck, which would hinder the vertical movement of the aluminum profile; the top of the adhesive strip is higher than the top of the aluminum profile, so that the adhesive strip contacts the fixing protrusions first during the process of the aluminum profile moving upward (towards the housing), avoiding hard contact between the aluminum profile and the fixing protrusions, and preventing wear and damage.

[0009] In another preferred embodiment, a groove is provided on the aluminum profile, and the lap bridge on the aluminum profile is set on the groove; the spring is connected to the bottom of the groove of the aluminum profile, and the position of the spring is defined by the fixing clip, two fixing protrusions and the groove on the aluminum profile, which ensures that the spring moves in a specific position and avoids the irregular movement of the spring, which cannot effectively drive the aluminum profile to move or cannot return to the original position, thus affecting the blocking and shielding of rays.

[0010] More preferably, the fixing clip includes a first fixing clip and a second fixing clip. The spring post is connected to the first fixing clip. One end of the spring is connected to the first fixing clip. The other end of the spring passes through the gap between the two fixing protrusions, the groove on the aluminum profile, and the lap bridge to connect to the second fixing clip. The second fixing clip is connected to the bottom of the groove on the aluminum profile through the spring. The spring, the second fixing clip, and the groove are all connected by screws to increase stability.

[0011] Most preferably, the elastic connecting component further includes a connecting rod, with its two ends connected to a first fixing clip near the spring post and a first fixing clip away from the spring post, respectively. The first fixing clip away from the spring post is connected to a spring, which passes through the gap between the two fixing protrusions, the groove on the aluminum profile, and the lap bridge to connect to a second fixing clip, which is connected to the housing. There is a gap at the connection between the first fixing clip away from the spring post, the spring, and the groove. The second fixing clip is connected to the housing by screws, which helps to stabilize the connection between the elastic connecting component and the housing. The connecting rod transmits the compressive force, causing multiple sets of springs to generate elastic force, which is more conducive to moving the aluminum profile.

[0012] More preferably, the connecting rod and the fixing clamp are connected by a snap-fit ​​mechanism. The connecting rod has bent portions at both ends, and the fixing clamp has holes. The bent portions fit into the holes, which facilitates installation, disassembly, maintenance, and replacement.

[0013] More preferably, the top of each fixing clamp is provided with a slot, the width of which is greater than the diameter of the connecting rod.

[0014] Preferably, the spring includes a thick end and a thin end, which are connected by threads. The thin end has a screw-like structure, with one end of the thin end threaded to the thick end and the other end snapped into the fixing clip. A spring is provided on the thin end between the thick end and the fixing clip. The threaded connection between the thick end and the thin end helps to control the length of the spring. The length of the thick end of the spring extending out of the door leaf can be adjusted according to the actual situation. The spring can play a buffering role.

[0015] Preferably, an extension is provided at the bottom of the side wall of the housing, which is connected to the door leaf. The height of the groove of the door leaf is the same as the height of the housing. The extension is connected to the door leaf by screws. This not only helps to stabilize the connection between the housing and the door leaf, but also facilitates installation and disassembly. When the door leaf is open, the height of the elastic connecting parts, rubber strips, aluminum profiles and lead plates combined is less than or equal to the height of the internal space of the housing. This prevents the rubber strips and lead plates from protruding from the door leaf when it is open, which would affect the appearance. It also avoids unnecessary contact that could cause damage to objects or scratches to people.

[0016] Preferably, the height of the lead plate is greater than or equal to the distance between the door leaf and the door frame. Under normal circumstances, the sum of the height of the lead plate and the thickness of the rubber strip is equal to the distance between the door leaf and the door frame. However, in order to prevent the distance between the door leaf and the door frame from increasing, such as due to door frame wear, the height of the lead plate is greater than or equal to the distance between the door leaf and the door frame. This means that the sum of the height of the lead plate and the thickness of the rubber strip is greater than the distance between the door leaf and the door frame. Even if the distance between the door leaf and the door frame increases, the rubber strip and the lead plate can still achieve a seal and block radiation.

[0017] In a more preferred embodiment, when the door frame is worn irregularly, an irregularly positioned rubber strip (matching the wear of the door frame) facing the door gap is used, along with a corresponding lead plate, to more effectively seal the gap between the door leaf and the door frame, blocking radiation. This eliminates the need to replace the protective door; only some components of the protective device need to be replaced, saving costs.

[0018] Preferably, the aluminum profile and the rubber strip are snap-fitted together, which facilitates installation, disassembly and maintenance.

[0019] The beneficial effects of this utility model are as follows:

[0020] 1. The device includes a housing, flexible connecting parts, rubber strips, aluminum profiles and lead plates. It has a simple structure, low cost, and is easy to install. In case of problems, it is easy to disassemble and repair. If some parts of the structure have problems or the size of the gap between the door leaf and the door frame, the parts can be replaced in time.

[0021] 2. The design of the flexible connecting components, especially the cooperation between the fixing clips, springs, spring posts and the housing, makes the elastic movement of the entire component more stable and less prone to problems; multiple springs can be set to ensure that the movement of the aluminum profile driving the lead plate and rubber strip is more stable, and the blocking and shielding of radiation is more reliable.

[0022] 3. The use of aluminum profiles facilitates the movement of the lead plate and rubber strip by the flexible connecting parts, as well as the placement of the lead plate and the installation of the rubber strip. It also contributes to the stability of the device and effectively avoids the problem of deformation that is common in conventional protective devices.

[0023] 4. The top of the rubber strip is higher than the top of the aluminum profile, which avoids hard contact between the aluminum profile and the fixing protrusion, thus preventing wear and damage.

[0024] 5. The height of the lead plate and the irregular arrangement of the lead plate and rubber strips help to increase the gap between the door leaf and the door frame. When the door frame is irregularly worn, it can achieve sealing, blocking and shielding radiation without replacing the protective door, thus saving costs. Attached Figure Description

Detailed Implementation

[0039] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection claimed in this application.

[0040] As shown in the figure, a concealed protective device includes a housing 2 (such as...). Figure 4 (As shown), elastic connecting parts, rubber strip 7, aluminum profile 5 and lead plate 4; the housing 2 is set in the groove at the bottom of the door leaf 15, and the top, front, back and left and right sides of the housing 2 are in contact with the door leaf 15. The side wall of the door leaf 15 is provided with a reserved opening 11 (as shown). Figure 1 As shown), the reserved opening 11 is connected to the groove, and the spring post 1 on the elastic connecting component is set in the reserved opening 11; as shown Figure 2-3 As shown, a flexible connecting component is provided in the housing 2. An aluminum profile 5 is connected below the flexible connecting component. A lead plate 4 is installed inside the aluminum profile 5, and a rubber strip 7 is installed outside the aluminum profile 5. The flexible connecting component is connected to the housing 2, and the housing 2 is connected to the door leaf 15. This concealed protective device can be hidden inside the door leaf 15. When the door leaf 15 is closed, the spring column 1 is squeezed, which in turn squeezes the flexible connecting component. The flexible connecting component, under external force, generates elasticity, causing it to move the aluminum profile 5 from inside the housing 2 towards the bottom of the door frame 16 until the rubber strip 7 abuts against the bottom of the door frame 16. At this time, the rubber strip 7 and the lead plate 4 seal the gap between the door leaf 15 and the door frame 16, blocking rays and shielding radiation. When the door leaf 15 is opened, the spring column 1 is no longer squeezed, so the force squeezing the flexible connecting component disappears, and the flexible connecting component returns to its original state. The flexible connecting component then retracts the aluminum profile 5, the rubber strip 7, and the lead plate 4 back into the housing 2.

[0041] Another implementation, such as Figure 2-3 , Figure 5As shown, the elastic connection component includes a spring post 1, a spring plate 9, and a fixing clip 10. Fixing protrusions 3 are correspondingly provided on both side walls of the housing 2. The top of the fixing protrusions 3 contacts the fixing clip 10. The spring post 1 is positioned above the fixing protrusions 3. The width of the spring plate 9 is less than the gap between the two fixing protrusions 3. The spring post 1 connects to the fixing clip 10, and the fixing clip 10 connects to one end of the spring plate 9. The other end of the spring plate 9 passes through the gap between the two fixing protrusions 3 and the lap bridge 14 on the aluminum profile 5, connecting to another fixing clip 10. This other fixing clip 10 connects to the aluminum profile 5 via the spring plate 9 and to the housing 2. Through the multiple functions of the fixing protrusions 3, the spring plate 9, the connection of the other fixing clip 10 to the housing 2, etc., the elastic connection component is stabilized. The connection between the fixing clamp 10 and the aluminum profile 5 effectively controls the aluminum profile 5. The spring 9 effectively connects the fixing clamp 10 and the aluminum profile 5, making the movement of the aluminum profile 5 both controllable and stable. When the door leaf 15 is closed, the door frame 16 presses the spring 1. The spring 1 is pressed and moves towards the spring 9, which in turn drives the fixing clamp 10 to move. The spring 9 is pressed and generates elastic force, which acts on the aluminum profile 5, the lead plate 4 and the rubber strip 7 to move downward (away from the housing 2). When the door leaf 15 is opened, the door frame 16 no longer presses the spring 1, the fixing clamp 10 returns to its original position, and the spring 9 returns to its original state. The springs connected to both ends of the fixing clamp 10 effectively raise the aluminum profile 5, the lead plate 4 and the rubber strip 7, returning them to their original state.

[0042] In another embodiment, the width of the bottom of the fixing clip 10 is greater than the gap between the fixing protrusions 3 on the two side walls of the housing 2, and the width of the top of the aluminum profile 5 is greater than the gap between the fixing protrusions 3 on the two side walls of the housing 2; the top of the adhesive strip 7 is higher than the top of the aluminum profile 5; the fixing protrusions 3 help stabilize the elastic connecting parts, prevent the fixing clip 10 from moving below the fixing protrusions 3, which would hinder the movement of the elastic connecting parts and the stability of the device, and prevent the aluminum profile 5 from moving between the two fixing protrusions 3 and getting stuck, which would hinder the up and down movement of the aluminum profile 5; the top of the adhesive strip 7 is higher than the top of the aluminum profile 5, so that when the aluminum profile 5 moves upward (towards the housing 2), the adhesive strip 7 contacts the fixing protrusions 3 first, avoiding hard contact between the aluminum profile 5 and the fixing protrusions 3, preventing wear and damage; a groove 8 is provided on the aluminum profile 5, and the overlapping bridge 14 on the aluminum profile 5 is provided on the groove 8 (e.g. Figure 7 (As shown); the spring 9 is connected to the bottom of the groove 8 of the aluminum profile 5. The position of the spring 9 is limited by the fixing clip 10, the two fixing protrusions 3 and the groove 8 on the aluminum profile 5, which ensures that the spring 9 moves in a specific position and avoids the irregular movement of the spring 9, which would not be able to effectively drive the aluminum profile 5 to move or return it to its original position. The lap bridge 14 on the aluminum profile 5 is set on the groove 8. The lap bridge 14 is formed by riveting the side wall of the groove 8 of the aluminum profile 5 to form a bridge-like structure.

[0043] Another implementation, such as Figure 5 As shown, the fixing clip 10 includes a first fixing clip 10-1 and a second fixing clip 10-2. The spring post 1 is connected to the first fixing clip 10-1. One end of the spring 9 is connected to the first fixing clip 10-1, and the other end of the spring 9 passes through the gap between the two fixing protrusions 3, the groove 8 on the aluminum profile 5, and the lap bridge 14 to connect to the second fixing clip 10-2. The second fixing clip 10-2 is connected to the bottom of the groove 8 through the spring 9. The spring 9, the second fixing clip 10-2, and the bottom of the groove 8 are all connected by screws to increase stability.

[0044] Another implementation method, different from... Figure 5 The connection method shown is as follows: Figure 6-10 As shown, the elastic connecting component also includes a connecting rod 13. The two ends of the connecting rod 13 are respectively connected to a first fixing clip 10-1 near the spring post 1 and a first fixing clip 10-1 away from the spring post 1. The first fixing clip 10-1 away from the spring post 1 is connected to a spring 9. The spring 9 passes through the gap between the two fixing protrusions 3, the groove 8 on the aluminum profile 5, and the overlapping bridge 14 to connect to a second fixing clip 10-2. The second fixing clip 10-2 is connected to the housing 2. There is a gap between the first fixing clip 10-1 away from the spring post 1 and the connection point between the spring 9 near the spring post 1 and the groove 8, meaning there is no connection between the first fixing clip 10-1 and the connection point between the spring 9 near the spring post 1 and the groove 8. The second fixing clip 10-2 is connected to the housing 2 by screws, which helps to stabilize the connection between the elastic connecting component and the housing 2. The connecting rod 13 transmits the compressive force, causing multiple sets of springs 9 to generate elastic force, which is more conducive to moving the aluminum profile 5. The connecting rod 13 and the fixing clip 10 are snap-fitted together, and both ends of the connecting rod 13 are provided with bent portions (such as...). Figure 12 As shown, the fixing clip 10 is provided with holes, and the bent part is adapted to the holes, which facilitates installation, disassembly and maintenance replacement.

[0045] Besides the differences mentioned above, such as Figure 5 In addition to the connection method mentioned above, there is another connection method, such as... Figure 11 As shown, this connection method is similar to... Figure 6-10 The differences are as follows: the second fixing clip 10-2, which is away from the spring post 1, is connected to the bottom of the groove 8 through the spring 9. The spring 9 is connected to the second fixing clip 10-2 and the groove 8 through screws. The second fixing clip 10-2 is connected to the housing 2 through screws.

[0046] In another embodiment, the spring 1 includes a thick end and a thin end (e.g., Figure 13As shown, the thick end and the thin end are connected by threads. The thin end is a screw-like structure, and the thick end is a cylinder with a screw hole inside. One end of the thin end is threaded to the thick end, and the other end is snapped into the fixing clamp. A spring 12 is provided on the thin end between the thick end and the fixing clamp 10. The threaded connection between the thick end and the thin end helps to control the length of the spring 1. The length of the thick end of the spring 1 extending out of the door leaf 15 can be adjusted according to the actual situation. The spring 12 can play a buffering role. The top of the fixing clamp 10 is provided with a slot. The width of the slot is greater than the diameter of the connecting rod 13. When the connecting rod is connected, it is easy for the connecting rod 13 to pass through the slot.

[0047] In another embodiment, an extension 6 is provided at the bottom of the side wall of the housing 2. The extension 6 is connected to the door leaf 15. The height of the groove of the door leaf 15 is the same as the height of the housing 2. The extension 6 is connected to the door leaf 15 by screws. This not only helps to stabilize the connection between the housing 2 and the door leaf 15, but also makes installation and disassembly convenient. When the door leaf 15 is open, the height of the elastic connecting parts, the rubber strip 7, the aluminum profile 5 and the lead plate 4 combined is less than or equal to the height of the internal space of the housing 2. That is, when the door leaf 15 is open, the bottom of the rubber strip 7 is flush with the door leaf 15 or the housing 2, or the horizontal height of the bottom of the rubber strip 6 is higher than the horizontal height of the bottom of the door leaf 15 or the bottom of the housing 2. This prevents the rubber strip 7 and the lead plate 4 from protruding from the door leaf 15 when it is open, which would affect the appearance. It also avoids unnecessary contact that could cause damage to objects or abrasions to the human body.

[0048] In another implementation, the height of the lead plate 4 is greater than or equal to the distance between the gap between the door leaf 15 and the door frame 16. Normally, the sum of the height of the lead plate 4 and the thickness of the adhesive strip 7 should be equal to the distance between the gap between the door leaf 15 and the door frame 16. However, to prevent the gap between the door leaf 15 and the door frame 16 from widening, such as due to wear on the door frame 16, the height of the lead plate 4 is greater than or equal to the distance between the gap between the door leaf 15 and the door frame 16. This means that the sum of the height of the lead plate 4 and the thickness of the adhesive strip 7 is greater than the distance between the gap between the door leaf 15 and the door frame 16. Even if the gap between the door leaf 15 and the door frame 16 widens, the adhesive strip 7 and the lead plate 4 will still... It can achieve sealing, blocking and shielding of radiation; when the door frame 16 is irregularly worn, an irregularly oriented rubber strip 7 (a rubber strip adapted to the wear of the door frame 16) is used, along with a corresponding lead plate 4, to more effectively seal the gap between the door leaf 15 and the door frame 16, blocking radiation. It does not require replacing the protective door, but only some components of the protective device, saving costs; the aluminum profile 5 and the rubber strip 7 are snap-fit ​​connected, with protrusions on the rubber strip 7 and corresponding grooves on the aluminum profile 5. The aluminum profile 5 and the rubber strip 7 are snap-fit ​​connected through the protrusions and grooves, which is convenient for installation, disassembly and maintenance.

[0049] In another embodiment, one side of the door leaf 15 is connected to the door frame 16. The spring post 1 is set on one side of the door leaf 15 near the connection between the door frame 16 and the door leaf 15. During the closing process of the door leaf, the spring post 1 is continuously squeezed. The length of the housing 2 is the same as the length of the rubber strip 7, the aluminum profile 5 and the lead plate 4. The length of the housing 2 is less than the length of the door leaf 15. The width of the housing 2 is less than the width of the door leaf 15. When the width of the housing 2 is less than the width of the door leaf 15, the bottom of the housing 2 is flush with the door leaf 15. When the width of the housing 2 is equal to the width of the door leaf 15, the sum of the thickness of the extension 6 of the housing 2 and the thickness of the door leaf 15 is the same as the height of the original door leaf 15.

[0050] In another embodiment, the connecting rod 13 is made of steel, the spring 9 is made of elastic spring steel sheet, and the fixing clip 10 is made of plastic.

[0051] In practical applications: the radiation protection door adopts the common radiation protection door technology, with built-in lead material to prevent radiation. The side of the door leaf 15 is hinged to the door frame 16. After the hidden protection device is installed, the housing 2 is connected and fastened to the door leaf 15 with screws. When the door leaf 15 is open, the bottom of the rubber strip 7 is level with or higher than the bottom of the door leaf 15, and the spring post 1 protrudes from the side wall of the door leaf 15. When the door leaf 15 is closed, the door frame 16 presses the spring post 1, and the spring post 1 moves away from the door frame 16, driving the first fixing clamp 10-1 away from the door frame 16, compressing the spring. Spring 9 drives aluminum profile 5, rubber strip 7, and lead plate 4 downward (away from housing 2) until rubber strip 7 abuts the bottom of door frame 16. Rubber strip 7 and lead plate 4 seal the gap between door leaf 15 and door frame 16 and block and shield rays. After door leaf 15 is opened, spring 1 is no longer squeezed by door frame 16. Spring 1 moves toward door frame 16 until it returns to its original position. First fixing clip 10-1 also returns to its original position. Spring 9 returns to its original state and drives aluminum profile 5, rubber strip 7, and lead plate 4 upward (towards housing 2) until they return to their original state.

[0052] This utility model provides a concealed protective device, which includes a housing 2, elastic connecting components, adhesive strips 7, aluminum profiles 5, and lead plates 4. It features a simple structure, low cost, and easy installation. In case of problems, it is easy to disassemble and repair. If any part of the structure malfunctions, or depending on the size of the gap between the door leaf 15 and the door frame 16, components can be replaced promptly. The elastic connecting components, especially the cooperation between the fixing clips 10, springs 9, and spring posts 1 and the housing 2, make the elastic movement of the entire component more stable and less prone to problems. The connecting rod 13 ensures more stable movement of the aluminum profile driving the lead plate 4 and adhesive strips 7, providing better protection against radiation. The aluminum profile 5 facilitates the movement of the lead plate 4 and the rubber strip 7 by the elastic connecting parts, and also facilitates the placement of the lead plate 4 and the installation of the rubber strip 7. It also contributes to the stability of the device, effectively preventing deformation problems common in conventional protective devices. The top of the rubber strip 7 is higher than the top of the aluminum profile 5, preventing hard contact between the aluminum profile 5 and the fixing protrusion 3, thus avoiding wear and damage. The height of the lead plate 4 and the irregular arrangement of the lead plate 4 and the rubber strip increase the gap between the door leaf 15 and the door frame 16. Even with irregular wear on the door frame 16, a seal can be achieved without replacing the protective door, blocking and shielding radiation, thus saving costs.
