Description

Technical Field

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

[0002] In hospitals, areas with strong radiation, such as the radiology department, radiotherapy department, and CT room, are hospital protection zones. Lead plates are usually installed on the walls of the protection zones to reduce radiation leakage. Lead plates are usually rolled into cylinders during transportation. When installing the 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 zones. Therefore, multiple operators are required to cooperate in the installation, resulting in high labor costs for installing the lead plates. Summary of the Invention

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

[0004] This application provides a hospital protection area protective lead plate installation structure using the following technical solutions:

[0005] A hospital protection area protective lead plate installation structure includes a rectangular ring frame, one side of the ring frame is covered and fixed with a lead plate, and the lead plate covers the outer wall of the ring frame, and the four end corners of the ring frame away from the lead plate are fixedly connected with fixing blocks;

[0006] Each of the ring frames is provided with a corresponding backing plate, and the backing plate is provided with a matching hole corresponding to the fixed block and for the fixed block to pass through;

[0007] Each of the fixing blocks is provided with a corresponding fixing tube, and the fixing tube, the backing plate and the ring frame are arranged in sequence in a direction away from the wall of the protection zone. Each fixing block is inserted into the corresponding fixing tube, and a mounting groove for accommodating the fixing tube is provided on the wall. The outer wall of the fixing tube protrudes outward at one end close to the backing plate to form a convex edge, which contacts the wall and is fixed to the wall by bolts.

[0008] The fixing cylinder is provided with a fixing assembly for fixing the backing plate, the fixing cylinder and the fixing block.

[0009] By adopting the above technical solution, when installing the lead plate, the operator lays out a line on the wall of the protection area to determine the installation point of the fixing tube, and then machines the installation groove at the installation point. The fixing tube is inserted into the installation groove, and the flange is fixed to the wall with bolts. The pad and ring frame are then installed. When installing the pad and ring frame, they are installed in a row from bottom to top and one by one from one side to the other. After the fixing groove is fixed, the operator inserts the fixing block into the corresponding matching hole, so that the pad and the corresponding ring frame are matched. Then, the ring frame and pad are moved closer to the wall to gradually insert the fixing block into the fixing tube.

[0010] As the fixed block moves along the fixed tube, the fixing assembly secures the fixed block, backing plate, and fixed tube. When the backing plate abuts against the ridge and the ring frame abuts against the backing plate, the ring frame and backing plate move into place. The fixing assembly secures the fixed block, backing plate, and fixed tube, completing the installation of one lead plate. The operator then follows the above steps to install the remaining lead plates. A single operator can complete the installation, reducing labor costs for lead plate installation.

[0011] Optionally, the fixing assembly includes a plurality of clamping plates slidably connected to the inner wall of the fixing cylinder, the length direction and sliding direction of the clamping plates are arranged along the axial direction of the fixing cylinder, and the plurality of clamping plates are evenly distributed along the circumference of the fixing cylinder;

[0012] 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 fixing block is smaller than the aperture of the matching hole. The sum of the diameter of the fixing block and the maximum thickness of the clamping plates above and below it is b1, and b1 is larger than the aperture of the matching hole.

[0013] The card plate is connected to a connecting spring, one end of the connecting spring away from the card plate is fixed to the inner bottom wall of the fixed cylinder, and the connecting spring enables the card plate to be located in the fixed cylinder;

[0014] The fixing assembly further comprises a transmission member for moving the clamping plate out of the fixing cylinder.

[0015] By adopting the above technical solution, when the fixed block moves into the fixed cylinder, the transmission member works to move the card plate out of the fixed cylinder, so that the card plate is inserted between the hole wall of the matching hole and the fixed block. As the fixed block continues to move, the thick side of the card plate continues to be inserted into the matching hole, so that the fixed block is pressed against the hole wall of the matching hole and the card plate, and the card plate, the fixed block and the pad can be fixed; when the fixed block moves into place, the card plate cooperates with the fixed block and the pad to prevent the transmission member from working, thereby preventing the card plate from resetting, so that the card plate, the fixed block and the pad remain fixed, that is, the ring frame, the pad and the fixed cylinder remain fixed.

[0016] Optionally, a soft rubber plate is embedded and fixed on one side of the clamping plate close to the center of the fixing cylinder, and the surface of the soft rubber plate is flush with the surface of the clamping plate.

[0017] By adopting the above technical solution, when the clamping plate, the backing plate and the fixing block are pressed tightly, the rubber soft plate contacts the fixing block, thereby better fixing the fixing block.

[0018] Optionally, a T-shaped slider is fixedly connected to the surface of the clamping plate close to the inner wall of the fixed cylinder, and a sliding groove corresponding to the slider 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 in the corresponding sliding groove.

[0019] By adopting the above technical solution, the slider cooperates with the slide groove, so that the clamping plate and the fixed cylinder are slidably connected.

[0020] Optionally, the transmission member includes a guide rod vertically fixedly connected to the inner bottom wall of the fixed cylinder, a driving block is slidably inserted on the guide rod, a limit spring is fixedly connected to the inner bottom wall of the fixed cylinder, the limit spring is fixed to the driving block, and the limit spring ensures that a distance exists between the driving block and the inner bottom wall of the fixed cylinder;

[0021] A transmission block corresponding to each of the card plates is slidably connected to the inner bottom wall of the mounting cylinder. The sliding direction of the transmission block is set along the direction of the line connecting the corresponding card plate and the axis of the mounting cylinder. A transmission rod hinged to the card plate is hinged on the transmission block. The transmission block is also hinged to a hinged rod hinged to the drive block. The ends of the transmission rod and the hinged rod away from the transmission block are both inclined toward the direction close to the convex edge.

[0022] An inserting groove for accommodating the guide rod is provided on the end surface of the fixing block away from the ring frame.

[0023] By adopting the above technical solution, when the fixed block moves toward the fixed cylinder, the guide rod is inserted into the plug-in slot. As the fixed block continues to move, the fixed block pushes the driving block to move in the direction close to the bottom wall of the fixed cylinder, and at the same time compresses the connecting spring. The driving block moves and drives the corresponding hinged rod to rotate, so that the hinged rod pushes the corresponding transmission block to move in the direction away from the guide rod. The movement of the transmission block drives the corresponding transmission rod to rotate, so that the transmission rod moves away from one end of the transmission block in the direction close to the convex edge, and pushes the corresponding card plate to move, so that the card plate moves out of the fixed cylinder, and the limit spring is stretched while the card plate moves; when the ring frame and the pad are moved into place, the card plate, the fixed block and the pad are clamped, so that the card plate is fixed, preventing the limit spring and the connecting spring from recovering their deformation, so that the card plate can maintain its position at this time.

[0024] Optionally, the cross-section of the transmission block is T-shaped, and a sliding groove corresponding to the transmission block is opened on the inner bottom wall of the fixed cylinder. The length direction of the sliding groove is set along the sliding direction of the transmission block, and each transmission block is slidably inserted in the corresponding sliding groove.

[0025] By adopting the above technical solution, the transmission block cooperates with the sliding groove, so that the transmission block is slidably connected to the fixed cylinder.

[0026] Optionally, the aperture of the plug-in slot at one end away from the ring frame gradually increases in a direction away from the ring frame.

[0027] By adopting the above technical solution, the guide rod can be inserted into the plug-in slot more smoothly.

[0028] Optionally, the fixed block, pad and card plate are all provided with through holes, which are vertically arranged. The through holes on the fixed block and the card plate pass through themselves, and the lower end of the through hole of the pad does not pass through the pad. Each of the pads 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 card plates and the through holes of the corresponding pad.

[0029] By adopting the above technical solution, when the ring frame and the pad are moved into place, the clamping plate is inserted into the matching hole. At this time, the through holes on the clamping plate, the fixed block and the pad are aligned. The operator inserts the vertical rod into the corresponding through hole. The vertical rod further fixes the pad, the fixed block and the clamping plate, making the fixing effect of the fixing tube, the pad and the ring frame more stable.

[0030] In summary, this application includes at least one of the following beneficial technical effects:

[0031] By arranging the fixing cylinder, the flange, the pad, the matching hole, the ring frame, the lead plate, the fixing block and the fixing assembly, one operator can complete the installation operation of the lead plate, thereby reducing the labor cost of installing the lead plate;

[0032] By arranging the clamping plate, the connecting spring, the guide rod, the driving block, the limit spring, the transmission block, the hinge rod, the transmission rod and the limit spring, the clamping plate can be driven to move out of the fixed cylinder while the fixed block moves into the fixed cylinder;

[0033] By arranging the vertical rods and the through holes, the vertical rods further fix the pad, the fixing block and the clamping plate, so that the fixing effect of the fixing cylinder, the pad and the ring frame is more stable. BRIEF DESCRIPTION OF THE DRAWINGS

The fixed cylinders 4 are inserted into these mounting slots 51. The outer wall of the fixed cylinder 4, near the end of the backing plate 3, protrudes outward to form a flange 41. The flange 41 is located between the wall 5 and the backing plate 3 and is fixed to the wall 5 with screws.

[0045] Reference Figure 4 、 Figure 5 and Figure 6 , a fixing assembly 6 is provided in the fixing cylinder 4 for fixing the fixing cylinder 4, the pad 3 and the fixing block 11; 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 plates 61 are arranged along the axial direction of the fixing cylinder 4, and the plurality of clamping plates 61 are evenly distributed along the circumference 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 plates 61 gradually increases from the side close to the convex edge 41 to the side away from the convex edge 41, the sum of the diameter of the fixing column and the maximum thickness of the two clamping plates 61 is b1, the sum of the diameter of the fixing column and the minimum thickness of the two clamping plates 61 is b2, b1 is larger than the aperture of the matching hole 31, and b2 is smaller than the aperture of the matching hole 31.

[0046] A T-shaped slider 611 is fixedly connected to the side wall of the card plate 61 close to the inner wall of the fixed cylinder 4, and a slide groove 42 corresponding to the slider 611 is opened on the inner wall of the fixed cylinder 4.

When the connecting spring 62 is not subjected to external force, the connecting spring 62 causes the card plate 61 to be located as a whole in the fixed cylinder 4.

[0047] Reference Figure 5 and Figure 6 The fixing assembly 6 also includes a transmission member 63 for moving the clamping plate 61 toward the outside of the fixed cylinder 4; the transmission member 63 includes a guide rod 631 vertically fixedly connected to the inner bottom wall of the fixed cylinder 4, the guide rod 631 is located as a whole in the fixed cylinder 4, and the guide rod 631 and the fixed cylinder 4 are coaxial; a driving block 632 is slidably inserted on the guide rod 631, and a limiting spring 633 is provided between the driving block 632 and the inner bottom wall of the fixed cylinder 4, and 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 fixed cylinder 4, and the limiting spring 633 creates a distance between the driving block 632 and the inner bottom wall of the fixed cylinder 4.

[0048] An insertion groove 111 corresponding to the guide rod 631 is provided on the end surface of the fixed block 11 away from the ring frame 1. The insertion groove 111 is used to accommodate the guide rod 631. In order to enable the guide rod 631 to be better inserted into the insertion groove 111, the aperture of the insertion groove 111 at the end away from the ring frame 1 gradually increases in the direction away from the ring frame 1; the guide rod 631 cooperates with the insertion groove 111 to guide the fixed block 11 so that the fixed block 11 can be more smoothly inserted into the fixed cylinder 4.

[0049] The transmission member 63 also includes a transmission block 634 corresponding to the card plate 61 one by one. The cross-section of the transmission block 634 is T-shaped. A sliding groove 43 corresponding to the transmission block 634 is opened on the inner bottom wall of the fixed cylinder 4. The connection direction between the card plate 61 corresponding to the transmission block 634 and the guide rod 631 is the length direction of the sliding groove 43. Each transmission block 634 is slidably inserted in the corresponding sliding groove 43; a transmission rod 636 is hinged on the transmission block 634, and the end of the transmission rod 636 away from the transmission block 634 is inclined toward the direction close to the card plate 61 and the protrusion 41, and the end of the transmission rod 636 away from the transmission block 634 is hinged to the corresponding card plate 61; a hinged rod 635 is also hinged on the transmission block 634, and the end of the hinged rod 635 away from the transmission block 634 is inclined toward the direction close to the drive block 632 and the protrusion 41, and the end of the hinged rod 635 away from the transmission block 634 is hinged to the drive block 632.

[0050] When installing the lead plates 2, the operator lays out the wall 5 to determine the installation points of the fixing tubes 4, and opens an installation groove 51 at each point. Then, a fixing tube 4 is inserted into each installation groove 51, and the flange 41 is fixed to the wall 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 one by one from one side to the other.

[0051] When installing the lead plate 2, the operator inserts the pad 3 onto the fixed block 11, and faces the pad 3 toward the wall 5, inserts the fixed block 11 into the fixed tube 4, and the guide rod 631 enters the insertion slot 111. The guide rod 631 cooperates with the insertion slot 111 to guide the fixed block 11. As the fixed block 11 continues to move, the fixed block 11 pushes the driving block 632 to move toward the inner bottom wall of the fixed tube 4, and at the same time compresses the connecting spring 62; the movement of the driving block 632 drives the hinged rod 635 to rotate, so that the hinged rod 635 pushes the corresponding transmission block 634 to move away from the guide rod 631.

[0052] The movement of the transmission block 634 drives the corresponding transmission rod 636, causing it to rotate. The end of the transmission rod 636, which is away from the transmission block 634, moves toward the ridge 41, pushing the corresponding clamping plate 61, causing it to move outward from the fixed tube 4 and 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 against the fixed block 11 and the wall of the mating hole 31. When the backing plate 3 abuts against the ridge and the ring frame 1 abuts against the backing plate 3, the ring frame 1 moves into place. The clamping plate 61 now engages with the fixed block 11 and the wall of the mating hole 31, securing the ring frame 1, backing plate 3, and fixed tube 4 and preventing the connecting spring 62 and the limit spring 633 from recovering their deformation. The operator then installs the remaining lead plates 2 according to the above operation, allowing a single operator to independently install the lead plates 2, reducing the labor cost of installing the lead plates 2.

[0053] Reference Figure 5 In order to further strengthen the fixing effect of the ring frame 1, the pad 3 and the fixing tube 4, a rubber soft plate 64 is embedded on the side wall of the clamping plate 61 away from the inner wall of the fixing tube 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. The surface of the rubber soft plate 64 is also provided with anti-slip grooves.

[0054] Reference Figure 5 and Figure 6 Each pad 3 is also provided with two vertical rods 7, and each fixing block 11, card plate 61 and pad 3 are provided with a through hole 8 adapted to the vertical rod 7. The through holes 8 on the fixing block 11 and the card plate 61 pass through themselves, and the lower end of the through hole 8 on the pad 3 does not pass through the pad 3. The two fixing blocks 11 arranged in the vertical direction correspond to one vertical rod 7; when the ring frame 1 is installed in place, the through holes 8 on the fixing block 11, card plate 61 and pad 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 pad 3.

[0055] The implementation principle of the protective lead plate installation structure of a hospital protection area in an embodiment of the present application is as follows: when installing the lead plate 2, the operator first lays out the line on the wall 5, determines the installation point of the fixed tube 4, and opens the installation groove 51 at the point, inserts the fixed tube 4 into each installation groove 51, and fixes the protruding edge 41 to the wall 5 with screws, and then installs the pad 3 and the ring frame 1, and performs the construction in the order of installing row by row from bottom to top and one by one from one side to the other.

[0056] When installing the lead plate 2, insert the pad 3 into the fixed block 11 so that the ring frame 1 cooperates with the pad 3, and then move the ring frame 1 and the pad 3 in the direction close to the wall 5, so that the fixed block 11 is inserted into the corresponding fixed tube 4; when the pad 3 is pressed against the protruding edge 41 and the ring frame 1 is pressed against the pad 3, the ring frame 1 and the pad 3 are moved into place, and the card plate 61 is inserted into the matching hole 31, and the card plate 61 is pressed against the hole wall of the matching hole 31 and the fixed block 11, and the through holes 8 on the card plate 61, the plug-in plate and the pad 3 are aligned, and finally the vertical rod 7 is inserted into the corresponding through hole 8, and the remaining lead plates 2 are installed according to the above steps.

[0057] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
