Description

Technical Field

[0001] This utility model relates to the field of fire door technology, and in particular to a radiation-proof fire door. Background Technology

[0002] With the rapid development of fields such as nuclear energy, medical imaging, and industrial flaw detection, radiation protection and fire safety have become core requirements for special locations. Traditional doors and windows cannot simultaneously meet multiple performance requirements, including radiation shielding, fire resistance, and structural strength.

[0003] Radiation-proof fireproof doors are special doors designed for scenarios with high radiation risk and high fire hazard. Through the innovative integration of materials science and structural engineering, they achieve the dual core functions of radiation shielding and fire resistance, and are key equipment in the field of industrial and building safety protection.

[0004] After prolonged use, the lead plates installed inside the device may experience performance degradation due to impact, aging, or radiation damage. Since most of the lead plates inside existing devices are integrated with the door body, they cannot be replaced individually. This would require replacing the entire door body, increasing maintenance costs. Furthermore, while other parts of the door may remain intact, the non-removable lead plates would necessitate the complete scrapping of the entire device, resulting in a waste of resources such as steel and flame-retardant materials. Therefore, we propose a radiation-proof fireproof door to address these issues. Utility Model Content

[0005] The main purpose of this utility model is to provide a radiation-proof and fireproof door that can effectively solve the above problems.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A radiation-proof and fireproof door includes a door frame, a door frame rotatably connected to the inner wall of the door frame, a handle fixedly connected to the front of the door frame, a disassembly assembly inside the door frame, and an anti-collision assembly inside the door frame.

[0008] Preferably, the disassembly assembly includes two worm gears, which are arranged vertically with the center of the gantry as the symmetrical point. The left and right outer surfaces of the worm gears are rotatably connected to the inner wall of the gantry, and a lead plate is engaged with the inner wall of the gantry.

[0009] Preferably, a worm gear is meshed with the side of the worm gear away from the center of the gantry, and a rotating shaft is fixedly connected to the inner wall of the worm gear. The outer surfaces of the front and back of the rotating shaft are rotatably connected to the inner wall of the gantry, and a rotating block is fixedly connected to the back of the rotating shaft.

[0010] Preferably, the worm gear has threads on both its left and right outer surfaces, and the two threads are arranged in opposite directions. Two moving blocks are threadedly connected to the outer surface of the worm gear. A rotating rod is rotatably connected to the inner wall of the two moving blocks on the side closer to the center of the gantry. A limit plate is rotatably connected to the outer surface of the two rotating rods on the side away from the worm gear. The outer surface of the limit plate is slidably connected to the inner wall of the gantry.

[0011] Preferably, an mounting plate is installed on the back of the gantry, the back of the limiting plate is in contact with the front of the mounting plate, and the front of the limiting plate is in contact with the back of the lead plate.

[0012] Preferably, the anti-collision component includes a fixing frame, the outer surface of which is fixedly connected to the inner wall of the gantry, the back of which is in contact with the front of the lead plate, and an anti-collision plate is slidably connected to the outer surface of the front of the fixing frame.

[0013] Preferably, each of the four corners of the anti-collision plate is fixedly connected to a connecting block, and each of the four connecting blocks is slidably connected to a fixing rod on its inner wall. The back of each of the four fixing rods is fixedly connected to the front of the fixing frame.

[0014] Preferably, springs are fitted onto the outer surfaces of all four fixing rods, the front of each of the four springs is fixedly connected to the back of the connecting block on the same side, and the back of each of the four springs is fixedly connected to the front of the fixing frame.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. This utility model, by setting up a disassembly component, specifically involves first removing the mounting plate, then rotating two rotating blocks counterclockwise to drive two worm gears to rotate within the inner wall of the gantry. When the worm gears rotate counterclockwise, they will drive the limiting plate to move, thus releasing the restriction on the lead plate, which can then be directly removed for replacement without replacing the entire gantry. This not only reduces the maintenance cost of the device, but also avoids the waste of resources such as steel and flame-retardant materials because the lead plate can be disassembled separately.

[0017] 2. This utility model incorporates an anti-collision component. Specifically, when the fire door is impacted from the front, the anti-collision plate slides on the outer surface of the fixed frame, compressing the spring and causing it to deform. This buffers and offsets the moving force generated by the impact on the anti-collision plate. This not only avoids problems such as deformation, cracking, or weld point detachment caused by hard collisions, extending the service life of the device, but also reduces the frequency of maintenance due to impacts, thereby reducing safety hazards and economic losses caused by maintenance interruptions to the protective function.

Detailed Implementation

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] Example 1, as Figure 1-5 As shown, a radiation-proof fireproof door includes a door frame 1, a door frame 11 rotatably connected to the inner wall of the door frame 1, a handle 12 fixedly connected to the front of the door frame 11, a disassembly assembly 2 inside the door frame 11, and an anti-collision assembly 3 inside the door frame 11.

[0026] Specifically, in order to achieve the goal of being able to replace the lead plates individually, see [link / reference]. Figure 2 and Figure 4 In this embodiment, the disassembly assembly 2 includes two worm gears 22, which are arranged vertically with the center of the gantry 11 as the symmetrical point. The left and right outer surfaces of the worm gears 22 are rotatably connected to the inner wall of the gantry 11, and a lead plate 21 is engaged with the inner wall of the gantry 11.

[0027] Further reading Figure 4 In this embodiment, a worm gear 232 is meshed with the side of the worm gear 22 away from the center of the gantry 11. A rotating shaft 23 is fixedly connected to the inner wall of the worm gear 232. The outer surfaces of the front and back sides of the rotating shaft 23 are rotatably connected to the inner wall of the gantry 11. A rotating block 231 is fixedly connected to the back side of the rotating shaft 23.

[0028] Further reading Figure 4In this embodiment, the worm gear 22 has threads on its left and right outer surfaces, and the two threads are arranged in opposite directions. Two moving blocks 24 are threadedly connected to the outer surface of the worm gear 22. The inner walls of the two moving blocks 24 near the center of the gantry 11 are rotatably connected to rotating rods 241. The outer surfaces of the two rotating rods 241 away from the worm gear 22 are rotatably connected to a limiting plate 242. The outer surface of the limiting plate 242 is slidably connected to the inner wall of the gantry 11.

[0029] Further reading Figure 2 and Figure 5 In this embodiment, an mounting plate 25 is installed on the back of the gantry 11, the back of the limiting plate 242 is in contact with the front of the mounting plate 25, and the front of the limiting plate 242 is in contact with the back of the lead plate 21.

[0030] During implementation, when the lead plate 21 is damaged and needs to be replaced, first remove the mounting plate 25 by unscrewing the screws. Then, rotate the two rotating blocks 231 counterclockwise. When the rotating blocks 231 rotate, they will drive the rotating shaft 23 to rotate within the inner wall of the gantry 11. When the rotating shaft 23 rotates counterclockwise, it will drive the worm gear 232 to rotate. Simultaneously, the worm gear 232 will drive the worm 22 to rotate within the inner wall of the gantry 11. The counterclockwise rotation of the worm 22 will drive the two moving blocks 24 to move away from each other within the inner wall of the gantry 11. When the device moves, it will cause the rotating rod 241 to rotate. When the rotating rod 241 rotates, it will cause the limiting plate 242 to move closer to the worm gear 22. After the limiting plate 242 moves a certain distance, its right surface will separate from the left surface of the lead plate 21. When the restriction on the lead plate 21 can be released by moving the two limiting plates 242, it can be directly removed and replaced without replacing the entire door. This not only reduces the maintenance cost of the device, but also avoids the waste of resources such as steel and flame-retardant materials because the lead plate 21 can be disassembled separately.

[0031] Example 2: This example adds anti-collision components based on Example 1.

[0032] Specifically, in order to achieve the purpose of buffering and offsetting the impact force received by the device, see [reference needed]. Figure 1 and Figure 3 In this embodiment, the anti-collision component 3 includes a fixing frame 31, the outer surface of the fixing frame 31 is fixedly connected to the inner wall of the gantry 11, the back of the fixing frame 31 is in contact with the front of the lead plate 21, and an anti-collision plate 32 is slidably connected to the outer surface of the front of the fixing frame 31.

[0033] Further reading Figure 3 In this embodiment, each of the four corners of the anti-collision plate 32 is fixedly connected to a connecting block 34, and each of the four connecting blocks 34 is slidably connected to a fixing rod 33. The back of each of the four fixing rods 33 is fixedly connected to the front of the fixing frame 31.

[0034] Further reading Figure 3 In this embodiment, springs 331 are sleeved on the outer surfaces of the four fixing rods 33. The front of each of the four springs 331 is fixedly connected to the back of the connecting block 34 on the same side, and the back of each of the four springs 331 is fixedly connected to the front of the fixing frame 31.

[0035] During implementation, when the fire door is impacted from the front, the object will first come into contact with the anti-collision plate 32. The impacted anti-collision plate 32 will slide on the outer surface of the fixing frame 31. As the anti-collision plate 32 slides, it will drive the four connecting blocks 34 to slide on the outer surface of the corresponding fixing rods 33. When the connecting blocks 34 slide, they will compress the springs 331, causing them to deform. The deformed springs 331 will generate elastic force. As the connecting blocks 34 continue to slide, the elastic force generated by the springs 331 will gradually increase, so that the movement force generated by the impact on the anti-collision plate 32 can be buffered and offset. This not only avoids problems such as deformation, cracking or weld point detachment caused by hard collisions, but also extends the service life of key components such as door frame, hinges, and locks. It can also reduce the frequency of maintenance caused by impacts and reduce the safety hazards and economic losses caused by maintenance interruption of the protective function.

[0036] The working principle of this utility model is as follows: When the lead plate 21 is damaged and needs to be replaced, firstly, remove the mounting plate 25 by unscrewing the screws. Then, rotate the two rotating blocks 231 counterclockwise. When the rotating blocks 231 rotate, they will drive the rotating shaft 23 to rotate within the inner wall of the frame 11. When the rotating shaft 23 rotates counterclockwise, it will drive the worm gear 232 to rotate. Simultaneously, when the worm gear 232 rotates counterclockwise, it will drive the worm 22 to rotate within the inner wall of the frame 11. When the worm 22 rotates counterclockwise, it will drive the two moving blocks 24 to move away from each other within the inner wall of the frame 11. When block 24 moves, it will drive the rotating rod 241 to rotate. When the rotating rod 241 rotates, it will drive the limiting plate 242 to move closer to the worm gear 22. When the limiting plate 242 moves a certain distance, its right surface will separate from the left surface of the lead plate 21. When the restriction on the lead plate 21 can be released by driving the two limiting plates 242 to move, it can be directly removed and replaced without replacing the entire door. This not only reduces the maintenance cost of the device, but also avoids the waste of resources such as steel and flame-retardant materials because the lead plate 21 can be disassembled separately.

[0037] When the fire door is impacted from the front, the object will first come into contact with the anti-collision plate 32. The impacted anti-collision plate 32 will slide on the outer surface of the fixing frame 31. As the anti-collision plate 32 slides, it will drive the four connecting blocks 34 to slide on the outer surface of the corresponding fixing rods 33. When the connecting blocks 34 slide, they will compress the springs 331 and cause them to deform. The deformed springs 331 will generate elastic force. As the connecting blocks 34 continue to slide, the elastic force generated by the springs 331 will gradually increase, so that the movement force generated by the impact on the anti-collision plate 32 can be buffered and offset. This not only avoids problems such as deformation, cracking or weld point detachment caused by hard collisions, but also extends the service life of key components such as door frame, hinges, and locks. It can also reduce the frequency of maintenance caused by impacts and reduce the safety hazards and economic losses caused by maintenance interruption of the protective function.
