Description

Technical Field

[0001] This application relates to the technical field of protective lead plates, and in particular to a lead plate installation structure for protective construction of radiation medical rooms. Background Technology

[0002] The main purpose of installing lead plates in radiological medical rooms is to shield ionizing radiation. Lead's high density absorbs and blocks harmful rays, preventing radiation from leaking into the surrounding area, thereby protecting medical staff, patients, and the public from radiation hazards and ensuring that the working environment meets national radiation protection safety standards.

[0003] The core method for fixing lead plates in radiological medical rooms is bolt connection. The specific operation process is as follows: according to the design requirements, locate and drill through holes in the lead plate, select appropriate bolt assemblies, pass them through the holes in the lead plate, and anchor them to the wall embedded parts or base structure, ultimately achieving a reliable rigid connection between the lead protective layer and the building structure.

[0004] Regarding the aforementioned technologies, when lead plates are damaged and need to be replaced, workers must disassemble them by tightening a large number of bolts one by one. The operating space is limited, and the tools are inconvenient to use, which is time-consuming and labor-intensive. When installing new lead plates, it is necessary to accurately align the holes and retighten all bolts. The process is cumbersome and time-consuming, which seriously affects maintenance efficiency, resulting in low efficiency in lead plate replacement. Summary of the Invention

[0005] To improve the efficiency of lead plate replacement, this application provides a lead plate installation structure for radiation protection construction in medical radiation rooms.

[0006] The technical solution provided in this application for the installation structure of lead plates for protective construction of radiation therapy rooms is as follows:

[0007] A lead plate installation structure for radiation protection construction in a medical radiation room is disclosed. The structure is suitable for lead plates, with clearance grooves extending through opposite sides of the lead plate. It includes a connecting seat and a connecting pipe. The connecting seat is bolted to the wall. A insertion groove is provided on the side of the connecting seat facing away from the wall. The connecting seat has locking slots on opposite side walls of the insertion groove. A sleeve is fixed to the connecting seat at the insertion groove, communicating with the insertion groove. The connecting pipe and the clearance groove are interlocked and fitted. One end of the connecting pipe is closed, and the connecting pipe and the sleeve are interlocked and fitted. The two side walls of the closed end of the connecting pipe have through holes. Inside the closed end of the connecting pipe, there are two locking blocks. The two locking blocks are arranged opposite each other, with one end of each locking block extending into the through hole and corresponding to the other. The locking blocks and the locking slots are engaged and matched. Inside the connecting pipe, there is a first moving component for driving the two locking blocks to move away from each other and a second moving component for driving the two locking blocks to move towards each other. A fixing plate is fixed at the end of the connecting pipe away from the locking blocks. The fixing plate is parallel to the connecting seat. An operating hole is opened through the fixing plate and is connected to the inside of the connecting pipe.

[0008] By adopting the above technical solution, when installing the lead plate, first align the clearance groove of the lead plate and fit it onto the sleeve on the connector. Next, insert the closed end of the connecting pipe into the sleeve. When the connecting pipe is inserted to the set depth and the locking block aligns with the slot, the first moving component pushes the two locking blocks away from each other, causing the ends of the locking blocks to embed into the slots, achieving quick locking between the connecting pipe and the connector, thus firmly clamping the lead plate between the connector and the fixing plate. When replacing the lead plate, operate the second moving component through the operating hole. The second moving component drives the two locking blocks to move towards each other, causing the ends of the locking blocks to exit the slots. At this time, the connecting pipe can be easily pulled out, releasing the fixation of the lead plate and facilitating the removal of the old lead plate. The installation of a new lead plate repeats the above steps. No bolts need to be tightened, simplifying the disassembly and assembly process and improving the efficiency of lead plate replacement.

[0009] Optionally, the first moving component includes a push plate and a first spring. Two push plates are provided, and the two push plates are respectively fixedly connected to the opposite side of the two locking blocks. The push plates are parallel to each other, and the first spring is fixed between the two push plates. The push plates and the connecting pipe are slidably connected.

[0010] By adopting the above technical solution, during the process of inserting the closed end of the connecting pipe into the sleeve, the inner wall of the sleeve squeezes the locking block, causing the locking blocks to move towards each other and compress the first spring. After the connecting pipe moves to the set position, the locking block and the slot are aligned, the first spring releases its elastic force, and pushes the two locking blocks on both sides to move away from each other. The ends of the locking blocks are engaged in the slot, so that the first moving component realizes the function of driving the two locking blocks to move away from each other.

[0011] Optionally, guide rails are fixedly provided on the inner walls of opposite sides of the closed end of the connecting pipe. The length direction of the guide rails is parallel to the moving direction of the locking block. Two sliders are slidably connected inside the guide rails, and the two sliders are fixedly connected to the side walls of the two push plates respectively.

[0012] By adopting the above technical solution, the setting of the guide rail and slider provides precise guidance for the movement of the push plate and the locking block, ensuring that the push plate can slide smoothly along the set straight direction, preventing deviation or jamming, and improving the reliability and service life of the operation.

[0013] Optionally, an auxiliary plate is fixed inside the connecting pipe. The auxiliary plate is parallel to the length direction of the connecting pipe. A slide rod is provided on the auxiliary plate. The length direction of the slide rod is perpendicular to the auxiliary plate. The slide rod passes through the auxiliary plate and is slidably connected to the auxiliary plate. The second moving component includes a linkage plate and a pressing plate. The linkage plate is fixedly connected to the end of the slide rod near the push plate. The linkage plate is parallel to the auxiliary plate. Two pressing plates are provided. The two pressing plates are fixedly connected to the opposite ends of the linkage plate on the side away from the slide rod. The pressing plates are perpendicular to the auxiliary plate and parallel to the push plate. The side of the pressing plate away from the auxiliary plate is set as an inclined surface.

[0014] By adopting the above technical solution, when pressure is applied to the slide rod through the operating hole, the slide rod moves axially towards the locking block, driving the linkage plate and the pressing plate to move synchronously. After the inclined surface of the pressing plate contacts the push plate, as the pressing plate continues to move forward, its inclined surface presses the push plate towards the center of the connecting pipe, thereby overcoming the elastic force of the first spring and driving the two push plates and the locking block to move towards each other, thus unlocking.

[0015] Optionally, a button plate is fixedly provided at the end of the slide rod away from the linkage plate. The button plate and the operation hole are plugged into and adapted. A second spring is fixedly provided between the button plate and the auxiliary plate. The second spring is sleeved on the outside of the slide rod.

[0016] By adopting the above technical solution, the button plate is easy for the operator to apply force to. Under normal conditions, the second spring pushes the button plate and slide bar away from the locking block, disengaging the pressing plate from the push plate and ensuring that the unlocking action only occurs when needed, avoiding accidental operation. After releasing the button plate, the second spring automatically resets the second moving component.

[0017] Optionally, the side of the card block away from the push plate is set as an inclined surface.

[0018] By adopting the above technical solution, when the connecting tube is inserted into the sleeve, the inner wall of the sleeve port will contact the inclined surface of the locking block. The inclined surface design allows the inner wall of the sleeve to smoothly press the locking block towards the center of the connecting tube, facilitating insertion, reducing resistance, and achieving a smooth insertion and self-locking process.

[0019] Optionally, both the pressing plate and the fixing plate are made of lead plate.

[0020] By adopting the above technical solutions, lead-made pushplates and fixing plates can provide additional radiation shielding, ensuring that the operating hole area and the end of the connecting pipe will not become weak points for radiation leakage, thus guaranteeing the overall protection effect.

[0021] Optionally, the sleeve is provided with a support plate on each of the two outer side walls. The support plate is parallel to the sleeve. A movable rod is fixed on the side of the support plate facing the sleeve. The end of the movable rod away from the support plate passes through one side wall of the sleeve. The movable rod and the sleeve are slidably connected. A movable plate is fixed on the end of the movable rod inside the sleeve. The movable plate is parallel to the support plate. The side of the movable plate away from the connecting seat is set as an inclined surface.

[0022] By employing the above technical solution, during the insertion of the closed end of the connecting pipe into the sleeve, the outer wall of the closed end of the connecting pipe contacts the inclined surface of the moving plate. As the connecting pipe penetrates deeper, its outer wall presses against the inclined surface of the moving plate, pushing the moving plate, moving rod, and support plate away from the sleeve. The support plate ultimately presses tightly against the side wall of the lead plate clearance groove, providing additional lateral support and clamping force for the lead plate, enhancing the stability of the lead plate installation, and preventing it from shaking.

[0023] Optionally, a third spring is fixed between the support plate and the sleeve, and the third spring is sleeved outside the moving rod.

[0024] By adopting the above technical solution, when the connecting tube squeezes the two moving plates away from each other, the third spring is stretched. When the connecting tube is pulled out, the moving plate, moving rod and support plate automatically return to the initial position under the action of the third spring, which is convenient for the next installation.

[0025] Optionally, an anti-slip pad is fixed to the side of the support plate opposite to the moving rod.

[0026] By adopting the above technical solution, the anti-slip pad increases the friction between the support plate and the side wall of the lead plate clearance groove, further preventing the lead plate from shifting or sliding when subjected to external force or vibration, ensuring a more secure and reliable installation.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. The quick-locking / separation design of the card block and card slot, combined with the first moving component to achieve self-locking and the second moving component to achieve convenient unlocking, simplifies the disassembly and assembly steps of the lead plate, eliminates the need to tighten bolts, and improves the work efficiency of lead plate replacement.

[0029] 2. Lead fixing plates and push plates are used to ensure both quick disassembly and stable installation, while also ensuring the integrity of radiation protection and operational safety.

[0030] 3. Through the support plate, moving rod, moving plate and third spring structure set on the outside of the sleeve, the support plate is automatically driven to press against the side wall of the lead plate during the insertion and locking process of the connecting pipe, providing additional stable support and enhancing the overall rigidity and reliability of the lead plate installation.

[0036] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.

[0037] This application discloses a lead plate installation structure for the protective construction of a radiation medical room.

[0038] refer to Figure 1 A lead plate installation structure for radiation protection construction of a medical radiation room, applicable to lead plate 1, including a fixing plate 7, which is parallel to lead plate 1 and located on the side of lead plate 1 away from the wall.

[0039] refer to Figure 1 and Figure 2 Multiple clearance grooves 11 are provided on the side of the lead plate 1. The clearance grooves 11 are evenly distributed along the side of the lead plate 1 and pass through the opposite sides of the lead plate 1. A connecting seat 2 is provided at the clearance groove 11 of the lead plate 1. The connecting seat 2 is parallel to the lead plate 1 and is located on the side of the lead plate 1 away from the fixing plate 7. The connecting seat 2 is bolted to the wall. A sleeve 4 is welded to the side of the connecting seat 2 facing the lead plate 1. The length direction of the sleeve 4 is perpendicular to the connecting seat 2. The sleeve 4 passes through the clearance groove 11 and abuts against the fixing plate 7.

[0040] refer to Figure 2 , Figure 3 and Figure 4The connecting seat 2 has an insertion groove 21 at the connecting sleeve tube 4. The sleeve tube 4 and the insertion groove 21 are connected. The connecting seat 2 has a slot 22 on the opposite side walls of the insertion groove 21. The fixing plate 7 is fixed with a connecting tube 3 on the side facing the lead plate 1. The length direction of the connecting tube 3 is parallel to the length direction of the sleeve tube 4. The connecting tube 3 and the sleeve tube 4 are inserted and matched. The connecting tube 3 and the insertion groove 21 are inserted and matched. The end of the connecting tube 3 away from the fixing plate 7 is a closed end. The connecting tube 3 has a through hole 31 on the opposite side walls of the closed end. The connecting tube 3 has two locking blocks 32 inside the closed end. The locking blocks 32 are arranged opposite each other. One end of the two locking blocks 32 extends into the through hole 31. The locking blocks 32 and the slot 22 are locked and matched and correspond one to one. The opposite side of the two locking blocks 32 is set as an inclined surface. The locking block 32 is provided with a first moving component 5 that can drive the two locking blocks 32 to move away from each other.

[0041] The first moving component 5 includes a push plate 51 and a first spring 52. There are two push plates 51, which are parallel to each other and located between two locking blocks 32. The end of the locking block 32 near the push plate 51 is fixedly connected to the push plate 51 and corresponds to it. Guide rails 8 are fixedly provided on the inner walls of opposite sides of the connecting pipe 3. The length direction of the guide rails 8 is perpendicular to the push plate 51. Two sliders 81 are slidably connected inside the guide rails 8. The two sliders 81 are fixedly connected to the sides of the two push plates 51 respectively. The first spring 52 is fixedly located between the two push plates 51.

[0042] After the connecting seat 2 is fixed to the wall, the lead plate 1 is placed and the sleeve 4 passes through the relief groove 11. The lead plate 1 and the connecting seat 2 abut against each other. Then, the connecting pipe 3 and the sleeve 4 are aligned, and the fixing plate 7 is moved toward the lead plate 1. The fixing plate 7 drives the connecting pipe 3 to move. During the process of the connecting pipe 3 moving into the sleeve 4, the inclined surface of the locking block 32 first contacts the side wall of the sleeve 4. Under the pressure of the side wall of the sleeve 4, the two locking blocks 32 move toward the inside of the connecting pipe 3. The locking blocks 32 drive the push plate. When the first spring 52 is compressed, the end of the connecting tube 3 away from the fixed plate 7 abuts against the bottom wall of the insertion slot 21. The locking block 32 and the slot 22 are aligned. The first spring 52 releases its elastic force, pushing the two locking blocks 32 to move away from each other. The end of the locking block 32 is locked into the slot 22. At the same time, the fixed plate 7 and the lead plate 1 abut against each other. The fixed plate 7 and the connecting seat 2 complete the clamping and fixing of the lead plate 1. During the movement of the push plate 51, the push plate 51 drives the slider 81 to move within the guide rail 8.

[0043] refer to Figure 1 , Figure 2 and Figure 3The fixed plate 7 has an operating hole 71 through it, which is connected to the inside of the connecting pipe 3. A button plate 35 is provided in the operating hole 71, which is parallel to the fixed plate 7. An auxiliary plate 33 is fixed inside the connecting pipe 3, which is parallel to the fixed plate 7. A slide rod 34 is fixed on the side of the button plate 35 facing the auxiliary plate 33, which is perpendicular to the button plate 35. The end of the slide rod 34 away from the button plate 35 passes through the auxiliary plate 33, and the slide rod 34 and the auxiliary plate 33 are slidably connected. A second spring 36 is fixed between the button plate 35 and the auxiliary plate 33, which is sleeved on the outside of the slide rod 34. A second moving component 6 is provided at the end of the slide rod 34 away from the button plate 35, which can drive the two push plates 51 to move towards each other.

[0044] The second moving component 6 includes a linkage plate 61 and a pressing plate 62. The linkage plate 61 is fixedly connected to the end of the slide bar 34 away from the pressing plate 35. The linkage plate 61 is parallel to the auxiliary plate 33. There are two pressing plates 62. The two pressing plates 62 are fixedly connected to the opposite ends of the linkage plate 61 on the side away from the auxiliary plate 33. The side of the pressing plate 62 away from the linkage plate 61 is set as an inclined surface. The pressing plate 62 is parallel to the push plate 51. The pressing plate 35 and the fixing plate 7 are both made of lead plate 1.

[0045] When lead plate 1 needs to be replaced, press the pressing plate 35 from the operating hole 71 toward the connecting pipe 3. The pressing plate 35 drives the sliding rod 34 to move, the second spring 36 is compressed, the sliding rod 34 drives the linkage plate 61 to move, the linkage plate 61 drives the pressing plate 62 to move. During the movement of the pressing plate 62, the inclined surface of the pressing plate 62 contacts the side wall of the push plate 51. The two pressing plates 62 push the two push plates 51 to move toward each other. The push plate 51 drives the locking block 32 to move. The locking block 32 and the locking groove 22 are disengaged. Then, the fixing plate 7 is moved away from lead plate 1. The fixing plate 7 drives the connecting pipe 3 to move. The connecting pipe 3 and the sleeve pipe 4 are disengaged, and the fixing of lead plate 1 is released.

[0046] refer to Figure 1 , Figure 2 and Figure 3 Movable plates 92 are provided on the inner walls of opposite sides of the sleeve 4. The movable plates 92 are parallel to the sleeve 4 and are parallel to each other. Movable rods 91 are fixed on the opposite sides of the two movable plates 92. The movable rods 91 are perpendicular to the movable plates 92. The end of the movable rod 91 away from the movable plates 92 passes through one side wall of the sleeve 4. The movable rod 91 and the sleeve 4 are slidably connected. A support plate 9 is fixed on the end of the movable rod 91 outside the sleeve 4. The support plate 9 is parallel to the movable plates 92. An anti-slip pad 94 is fixed on the side of the support plate 9 away from the movable rod 91. In this embodiment, the anti-slip pad 94 is made of rubber. The side of the movable plate 92 away from the connecting seat 2 is set as an inclined surface. A third spring 93 is fixed between the support plate 9 and the sleeve 4. The third spring 93 is sleeved on the outside of the movable rod 91.

[0047] When the connecting pipe 3 is moved into the sleeve 4, the connecting pipe 3 first contacts the inclined surface at the end of the moving plate 92 and pushes the two moving plates 92 away from each other. The moving plate 92 drives the moving rod 91 to move, the moving rod 91 drives the support plate 9 to move, the support plate 9 drives the anti-slip pad 94 to move, and the third spring 93 is stretched. After the connecting pipe 3 and the inclined surface of the moving plate 92 are separated, the anti-slip pad 94 and the side wall of the relief groove 11 of the lead plate 1 are tightly abutted, providing additional lateral support and clamping force for the lead plate 1, and enhancing the stability of the lead plate 1 installation.

[0048] The implementation principle of the lead plate installation structure for the protective construction of a radiation medical room according to an embodiment of this application is as follows: During installation, the clearance groove 11 of the lead plate 1 is aligned and fitted into the sleeve 4 of the connecting seat 2, and then the closed end of the connecting pipe 3 is inserted into the sleeve 4. During the insertion process, the inner wall of the sleeve 4 presses against the inclined surface of the locking block 32, forcing the two locking blocks 32 to move towards each other against the elastic force of the first spring 52; when the connecting pipe 3 is inserted into place, the locking block 32 aligns with the slot 22 on the connecting seat 2, and the first spring 52 then pushes the two locking blocks 32 away from each other and into the slot 22 to achieve locking. At the same time, the outer wall of the connecting pipe 3 contacts and presses against the inclined surface of the moving plate 92, pushing the support plate 9 to move outward against the elastic force of the third spring 93, and tightly pressing the side wall of the clearance groove 11 of the lead plate 1 with the anti-slip pad 94 to provide additional support. When disassembling and replacing lead plate 1, press the pressing plate 35 through the operating hole 71. This drives the inclined surface of the pressing plate 62 to push the push plate 51 against the elastic force of the first spring 52, causing the locking block 32 to exit the locking slot 22 and release the lock, allowing the connecting tube 3 to be pulled out. After the connecting tube 3 is pulled out, the support plate 9 automatically resets under the action of the third spring 93, releasing the fixation on lead plate 1, and the old lead plate 1 can be removed. The entire replacement process does not require tightening bolts, making the operation simple and quick, thereby improving the work efficiency of lead plate 1 replacement.

[0049] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
