Description

Technical Field

[0001] The present application relates to the field of installation of lead plates in hospital protection areas, and in particular to an installation structure of a protective lead plate in a hospital protection area. Background Art

[0002] In a hospital, areas with strong radiation such as the radiology department, radiotherapy department, and CT room are hospital protection areas. Lead plates are usually installed on the walls of the protection areas to reduce radiation leakage. When transporting lead plates, they are usually rolled into cylinders. When installing lead plates, multiple operators are required to flatten the rolled lead plates and use bolts to fix the lead plates at multiple points on the walls of the hospital protection areas. Therefore, when installing lead plates, multiple operators need to cooperate in construction, resulting in high labor costs for installing lead plates. Summary of the Invention

[0003] In order to reduce the labor cost of installing lead plates, the present application provides an installation structure of a protective lead plate in a hospital protection area.

[0004] The installation structure of a protective lead plate in a hospital protection area provided by the present application adopts the following technical solutions: An installation structure of a protective lead plate in a hospital protection area includes a rectangular ring frame. One surface of the ring frame is covered and fixed with a lead plate, and the lead plate covers the outer side wall of the ring frame. Fixed blocks are fixedly connected to the four end corners of the surface of the ring frame away from the lead plate. One backing plate is correspondingly provided for each ring frame. Matching holes corresponding to the fixed blocks one by one and for the fixed blocks to pass through are formed on the backing plate. One fixing cylinder is correspondingly provided for each fixed block. The fixing cylinder, the backing plate, and the ring frame are arranged in sequence in a direction away from the wall surface of the protection area. Each fixed block is inserted into the corresponding fixing cylinder. An installation groove for accommodating the fixing cylinder is formed on the wall surface. A convex edge protrudes outward from one end of the outer wall of the fixing cylinder close to the backing plate. The convex edge contacts the wall surface, and the convex edge is fixed to the wall surface by bolts. A fixing component for fixing the backing plate, the fixing cylinder, and the fixed block is provided in the fixing cylinder.

[0005] By adopting the above technical solutions, when installing the lead plate, the operator lays out lines on the wall surface of the protection area to determine the installation positions of the fixing cylinders, processes installation grooves at the installation positions, inserts the fixing cylinders into the installation grooves, then fixes the convex edges to the wall surface by bolts, and then installs the backing plates and the ring frames. When installing the backing plates and the ring frames, the installation is carried out row by row from bottom to top and one by one from one side to the other side. After the fixing grooves are fixed, the operator inserts the fixed blocks into the corresponding matching holes to make the backing plate cooperate with the corresponding ring frame, and then moves the ring frame and the backing plate in a direction close to the wall surface to gradually insert the fixed blocks into the fixing cylinders.

[0006] During the process of the fixed block moving along the fixed cylinder, the fixing component works to fix the fixed block, the backing plate and the fixed cylinder. When the backing plate abuts against the convex edge and the ring frame abuts against the backing plate, the ring frame and the backing plate reach the in-place position. At this time, the fixing component completes the fixing of the fixed block, the backing plate and the fixed cylinder. At this time, the installation of one lead plate is completed, and the operator installs the remaining lead plates according to the above operations. One operator can complete the above installation operations, reducing the labor cost of installing lead plates.

[0007] Optionally, the fixing component includes a plurality of clamping plates slidably connected to the inner wall of the fixed cylinder. The length direction and the sliding direction of the clamping plates are both arranged along the axial direction of the fixed cylinder, and the plurality of clamping plates are evenly distributed along the circumferential direction of the fixed cylinder; The thickness of the clamping plate gradually increases from the side close to the convex edge to the side away from the convex edge. The diameter of the fixed block is smaller than the aperture of the mating hole. The sum of the diameter of the fixed block and the maximum thickness of the clamping plates on its upper and lower sides is b1, and b1 is greater than the aperture of the mating hole; A connecting spring is connected to the clamping plate, and the end of the connecting spring away from the clamping plate is fixed to the inner bottom wall of the fixed cylinder. The connecting spring keeps the clamping plate inside the fixed cylinder; The fixing component further includes a transmission member for moving the clamping plate out of the fixed cylinder.

[0008] By adopting the above technical solution, when the fixed block moves into the fixed cylinder, the transmission member works to move the clamping plate out of the fixed cylinder, so that the clamping plate is inserted between the hole wall of the mating hole and the fixed block. As the fixed block continues to move, the thick side of the clamping plate also continues to be inserted into the mating hole, so that the fixed block abuts tightly against the hole wall of the mating hole and the clamping plate, and can fix the clamping plate, the fixed block and the backing plate; when the fixed block moves into place, the clamping plate cooperates with the fixed block and the backing plate to prevent the transmission member from working, thereby preventing the clamping plate from resetting, and keeping the clamping plate, the fixed block and the backing plate fixed, that is, keeping the ring frame, the backing plate and the fixed cylinder fixed.

[0009] Optionally, a rubber soft plate is embedded and fixed on the side of the clamping plate close to the center of the fixed cylinder, and the surface of the rubber soft plate is flush with the surface of the clamping plate.

[0010] By adopting the above technical solution, when the clamping plate abuts tightly against the backing plate and the fixed block, the rubber soft plate contacts the fixed block, so that the fixed block can be better fixed.

[0011] Optionally, a T-shaped slider is fixedly connected to the surface of the clamping plate close to the inner wall of the fixed cylinder. A sliding groove corresponding to the slider one by one is opened on the inner wall of the fixed cylinder. The length direction of the sliding groove is arranged along the axial direction of the fixed cylinder, and each slider is slidably inserted into the corresponding sliding groove.

[0012] By adopting the above technical solution, the slider cooperates with the sliding groove to make the clamping plate slidably connected to the fixed cylinder.

[0013] Optionally, the transmission member includes a guide rod vertically and fixedly connected to the inner bottom wall of the fixed cylinder. A driving block is slidably inserted on the guide rod. A limiting spring is fixedly connected to the inner bottom wall of the fixed cylinder. The limiting spring is fixed to the driving block, and there is a distance between the driving block and the inner bottom wall of the fixed cylinder due to the limiting spring. On the inner bottom wall of the mounting cylinder, there are slidingly connected transmission blocks corresponding to the clamping plates one by one. The sliding direction of the transmission blocks is set along the direction of the line connecting the corresponding clamping plates and the axis of the mounting cylinder. On the transmission blocks, there are hinged transmission rods hinged to the clamping plates, and there are also hinged rods hinged to the driving blocks on the transmission blocks. The ends of both the transmission rod and the hinged rod far from the transmission block are inclined towards the direction close to the convex edge. On the end face of the fixed block away from the ring frame, there is a plugging groove for accommodating the guide rod.

[0014] By adopting the above technical solution, when the fixed block moves into the fixed cylinder, the guide rod is inserted into the plugging groove. As the fixed block continues to move, the fixed block pushes the driving block to move towards the inner bottom wall of the fixed cylinder, and at the same time compresses the connecting spring. The movement of the driving block drives the corresponding hinged rod to rotate, causing the hinged rod to push the corresponding transmission block to move away from the guide rod. The movement of the transmission block drives the corresponding transmission rod to rotate, causing the end of the transmission rod far from the transmission block to move towards the direction close to the convex edge and push the corresponding clamping plate to move, so that the clamping plate moves out of the fixed cylinder. While the clamping plate moves, it also stretches the limiting spring; when the ring frame and the backing plate move into place, the clamping plate is clamped by the fixed block and the backing plate, so that the clamping plate is fixed, preventing the limiting spring and the connecting spring from restoring deformation, and enabling the clamping plate to maintain its position at this time.

[0015] Optionally, the cross-section of the transmission block is T-shaped. On the inner bottom wall of the fixed cylinder, there are sliding grooves corresponding to the transmission blocks one by one. The length direction of the sliding grooves is set along the sliding direction of the transmission blocks, and each transmission block is slidably inserted into the corresponding sliding groove.

[0016] By adopting the above technical solution, the cooperation between the transmission block and the sliding groove enables the transmission block to be slidably connected to the fixed cylinder.

[0017] Optionally, the aperture of the plugging groove at the end away from the ring frame gradually increases along the direction away from the ring frame.

[0018] By adopting the above technical solution, the guide rod can be inserted into the plugging groove more smoothly.

[0019] Optionally, through holes are provided in the fixed block, the backing plate and the clamping plate. The through holes are vertically arranged. The through holes in the fixed block and the clamping plate penetrate through themselves, and the lower end of the through hole in the backing plate does not penetrate through the backing plate. Each backing plate corresponds to two vertical rods, and each vertical rod is inserted into the through holes of the corresponding two fixed blocks, the through holes of the corresponding four clamping plates and the through holes of the corresponding backing plate.

[0020] By adopting the above technical solution, when the ring frame and the backing plate are in place, the clamping plate is inserted into the mating hole. At this time, the through holes in the clamping plate, the fixed block and the backing plate are aligned. The operator inserts the vertical rod into the corresponding through hole, and the vertical rod further fixes the backing plate, the fixed block and the clamping plate, making the fixing effect of the fixed cylinder, the backing plate and the ring frame more stable.

[0021] To sum up, the present application includes at least one of the following beneficial technical effects: By providing the fixed cylinder, the convex edge, the backing plate, the mating hole, the ring frame, the lead plate, the fixed block and the fixing component, an operator can complete the installation operation of the lead plate, reducing the labor cost of installing the lead plate; By providing the clamping plate, the connecting spring, the guide rod, the driving block, the limiting spring, the transmission block, the hinged rod, the transmission rod and the limiting spring, while the fixed block moves into the fixed cylinder, the clamping plate can be driven to move out of the fixed cylinder; By providing the vertical rod and the through hole, the vertical rod further fixes the backing plate, the fixed block and the clamping plate, making the fixing effect of the fixed cylinder, the backing plate and the ring frame more stable.

[0029] The following further describes the present application in detail with reference to Figure 1-6 the accompanying drawings.

[0030] An installation structure of a lead plate for a hospital protection area is disclosed in an embodiment of the present application. Referring to Figure 1 and Figure 2 and Figure 3 , it includes a rectangular ring frame 1. One surface of the ring frame 1 is covered and fixed with a lead plate 2, and the lead plate 2 also covers and is fixed on the circumferential side wall of the ring frame 1; fixing blocks 11 are fixedly connected to four end corners of the surface of the ring frame 1 away from the lead plate 2. The fixing blocks 11 are cylindrical, and the fixing blocks 11 are perpendicular to the ring frame 1.

[0031] Referring to Figure 4 and Figure 5 , the installation structure of the lead plate for the hospital protection area further includes a pad 3 corresponding to the ring frame 1. The length of the pad 3 is the same as the length of the ring frame 1, and the width of the pad 3 is also the same as the width of the ring frame 1. The pad 3 is located on the side of the ring frame 1 close to the wall surface 5 of the protection area; matching holes 31 corresponding to the fixing blocks 11 are formed in the pad 3. The matching holes 31 penetrate through the pad 3, and the aperture of the matching holes 31 is larger than the diameter of the fixing blocks 11.

[0032] On the side of the pad 3 away from the ring frame 1, there are also fixed cylinders 4 corresponding to the driving blocks 632. Each driving block 632 is inserted into the corresponding fixed cylinder 4; installation grooves 51 corresponding to the fixed cylinders 4 are formed in the wall surface 5 of the protection area, and the fixed cylinders 4 are inserted into the installation grooves 51. An outer wall of one end of the fixed cylinder 4 close to the pad 3 protrudes outward to form a flange 41. The flange 41 is located between the wall surface 5 and the pad 3, and the flange 41 is fixed to the wall surface 5 by screws.

[0033] Referring to Figure 4 and Figure 5 and Figure 6, a fixing assembly 6 for fixing the fixing cylinder 4, the backing plate 3 and the fixing block 11 is provided in the fixing cylinder 4; the fixing assembly 6 includes a plurality of clamping plates 61 slidably connected to the inner wall of the fixing cylinder 4. The length direction and the sliding direction of the clamping plate 61 are both arranged along the axial direction of the fixing cylinder 4. The plurality of clamping plates 61 are evenly distributed along the circumferential direction of the fixing cylinder 4. In this embodiment, the number of clamping plates 61 in each fixing cylinder 4 is two; the thickness of the clamping plate 61 gradually increases from the side close to the flange 41 to the side away from the flange 41. The diameter of the fixing column and the sum of the maximum thicknesses of the two clamping plates 61 is b1, and the diameter of the fixing column and the sum of the minimum thicknesses of the two clamping plates 61 is b2. b1 is greater than the aperture of the mating hole 31, and b2 is less than the aperture of the mating hole 31.

[0034] A T-shaped slider 611 is fixedly connected to the side wall of the clamping plate 61 close to the inner wall of the fixing cylinder 4. A chute 42 corresponding to the slider 611 is opened on the inner wall of the fixing cylinder 4. The length direction of the chute 42 is arranged along the axial direction of the fixing cylinder 4. Each slider 611 is slidably inserted into the corresponding chute 42; a connecting spring 62 is provided in the chute 42. One end of the connecting spring 62 is fixed to the inner bottom wall of the fixing cylinder 4, and the other end of the connecting spring 62 is fixed to the corresponding slider 611. The connecting spring 62 limits the position of the slider 611 and the clamping plate 61. When the connecting spring 62 is not subjected to an external force, the connecting spring 62 makes the whole clamping plate 61 located in the fixing cylinder 4.

[0035] Refer to Figure 5 And Figure 6 , the fixing assembly 6 further includes a transmission member 63 for moving the clamping plate 61 out of the fixing cylinder 4; the transmission member 63 includes a guide rod 631 vertically and fixedly connected to the inner bottom wall of the fixing cylinder 4. The guide rod 631 is entirely located inside the fixing cylinder 4 and is coaxial with the fixing cylinder 4; a driving block 632 is slidably inserted on the guide rod 631. A limiting spring 633 is provided between the driving block 632 and the inner bottom wall of the fixing cylinder 4. The limiting spring 633 is sleeved on the guide rod 631. One end of the limiting spring 633 is fixed to the driving block 632, and the other end of the limiting spring 633 is fixed to the inner bottom wall of the fixing cylinder 4. The limiting spring 633 keeps a distance between the driving block 632 and the inner bottom wall of the fixing cylinder 4.

[0036] A plugging groove 111 corresponding to the guide rod 631 is opened on the end face of the fixing block 11 away from the ring frame 1. The plugging groove 111 is used to accommodate the guide rod 631. In order to enable the guide rod 631 to be better inserted into the plugging groove 111, the aperture of the plugging groove 111 at the end away from the ring frame 1 gradually increases along the direction away from the ring frame 1; the guide rod 631 cooperates with the plugging groove 111 and can also guide the fixing block 11 so that the fixing block 11 can be inserted into the fixing cylinder 4 more smoothly.

[0037] The transmission member 63 further includes drive blocks 634 corresponding one-to-one to the clamping plates 61. The cross-section of the drive block 634 is T-shaped. Sliding grooves 43 corresponding one-to-one to the drive blocks 634 are formed on the inner bottom wall of the fixed cylinder 4. The direction of the line connecting the corresponding clamping plate 61 of the drive block 634 and the guide rod 631 is the length direction of the sliding groove 43. Each drive block 634 is slidably inserted into the corresponding sliding groove 43; a transmission rod 636 is hinged to the drive block 634. One end of the transmission rod 636 away from the drive block 634 is inclined towards the direction close to the clamping plate 61 and the flange 41. One end of the transmission rod 636 away from the drive block 634 is hinged to the corresponding clamping plate 61; an articulated rod 635 is also hinged to the drive block 634. One end of the articulated rod 635 away from the drive block 634 is inclined towards the direction close to the drive block 632 and the flange 41. One end of the articulated rod 635 away from the drive block 634 is hinged to the drive block 632.

[0038] When installing the lead plate 2, the operator lays out the wall surface 5 to determine the installation positions of the fixed cylinders 4, and opens installation grooves 51 at each position. Then, a fixed cylinder 4 is inserted into each installation groove 51, and the flange 41 is fixed to the wall surface 5 by bolts; then the operator installs the lead plates 2 one by one. During installation, the construction is carried out in the order of installing row by row from bottom to top and installing one by one from one side to the other side.

[0039] When installing the lead plate 2, the operator inserts the cushion plate 3 onto the fixed block 11, faces the cushion plate 3 towards the wall surface 5, inserts the fixed block 11 into the fixed cylinder 4. The guide rod 631 enters the insertion groove 111. The guide rod 631 and the insertion groove 111 cooperate to guide the fixed block 11. As the fixed block 11 continues to move, the fixed block 11 pushes the drive block 632 to move towards the direction close to the inner bottom wall of the fixed cylinder 4, and simultaneously compresses the connecting spring 62; the movement of the drive block 632 drives the articulated rod 635 to rotate, so that the articulated rod 635 pushes the corresponding drive block 634 to move away from the guide rod 631.

[0040] The movement of the transmission block 634 drives the corresponding transmission rod 636 to move, thereby causing the transmission rod 636 to rotate. One end of the transmission rod 636 away from the transmission block 634 moves towards the direction close to the convex edge 41, and pushes the corresponding clamping plate 61 to move, so that the clamping plate 61 moves outwards from the fixed cylinder 4 and inserts into the mating hole 31. As the operator continues to move the ring frame 1, the clamping plate 61 continues to insert into the mating hole 31 and further abuts tightly against the fixed block 11 and the hole wall of the mating hole 31. When the backing plate 3 abuts tightly against the convex ring and the ring frame 1 abuts tightly against the backing plate 3, the ring frame 1 moves into place. At this time, the clamping plate 61 cooperates with the fixed block 11 and the hole wall of the mating hole 31, and can fix the ring frame 1, the backing plate 3 and the fixed cylinder 4, and prevent the connecting spring 62 and the limiting spring 633 from restoring deformation; the operator installs the remaining lead plates 2 according to the above operations, so that an operator can independently install the lead plates 2, reducing the labor cost of installing the lead plates 2.

[0041] Referring to Figure 5 , in order to further strengthen the fixing effect on the ring frame 1, the backing plate 3 and the fixed cylinder 4, a rubber soft plate 64 is embedded on the side wall of the clamping plate 61 away from the inner wall of the fixed cylinder 4. The rubber soft plate 64 is fixed to the clamping plate 61, and the surface of the rubber soft plate 64 is flush with the surface of the clamping plate 61. Anti-slip lines are also provided on the surface of the rubber soft plate 64.

[0042] Referring to Figure 5 With Figure 6 , two vertical rods 7 are correspondingly arranged for each backing plate 3. Through holes 8 adapted to the vertical rods 7 are provided on each of the fixed blocks 11, the clamping plates 61 and the backing plates 3. The through holes 8 on the fixed blocks 11 and the clamping plates 61 penetrate through themselves, and the lower ends of the through holes 8 on the backing plates 3 do not penetrate through the backing plates 3. Two vertically arranged fixed blocks 11 correspond to one vertical rod 7; when the ring frame 1 is installed in place, the through holes 8 on the fixed blocks 11, the clamping plates 61 and the backing plates 3 are aligned. At this time, the operator inserts the vertical rod 7 into the corresponding through hole 8, and the upper end of the vertical rod 7 is not higher than the upper surface of the backing plate 3.

[0043] The implementation principle of the installation structure of the lead plate for the hospital protection area in the embodiment of the present application is as follows: when installing the lead plate 2, the operator first lays out lines on the wall surface 5 to determine the installation points of the fixed cylinders 4, opens installation grooves 51 at the points, inserts the fixed cylinders 4 into each installation groove 51, and fixes the convex edges 41 to the wall surface 5 with screws. Then, the backing plates 3 and the ring frames 1 are installed, and the construction is carried out in the order of installing row by row from bottom to top and installing one by one from one side to the other side.

[0044] When installing the lead plate 2, insert the backing plate 3 onto the fixing block 11 so that the ring frame 1 cooperates with the backing plate 3. Then, move the ring frame 1 and the backing plate 3 towards the wall surface 5, so that the fixing block 11 is inserted into the corresponding fixing cylinder 4. When the backing plate 3 abuts against the convex edge 41 and the ring frame 1 abuts against the backing plate 3, the ring frame 1 and the backing plate 3 are in place. At this time, the clamping plate 61 is inserted into the mating hole 31, and the clamping plate 61 abuts against the hole wall of the mating hole 31 and the fixing block 11. The through holes 8 on the clamping plate 61, the plugging plate, and the backing plate 3 are aligned. Finally, insert the vertical rod 7 into the corresponding through hole 8. According to the above steps, install the remaining lead plates 2.

[0045] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
