Description

Technical Field

[0001] This utility model relates to the field of radiation protection lead screen technology, specifically to a radiation protection lead screen. Background Technology

[0002] Lead screens are devices used to protect operators and patients of medical imaging equipment. They effectively block and absorb X-rays and other radiation, protecting the human body from radiation damage. The principle behind this is that lead's high density and high atomic number reduce radiation intensity by absorbing and scattering X-rays.

[0003] In actual radioactive workplaces, such as hospital radiology departments and nuclear industry laboratories, the spatial layout and equipment placement are often irregular. Traditional fixed-size lead screens are difficult to fully adapt to these complex environments, easily creating blind spots in protection. Furthermore, their width cannot be adjusted, which means that the width of the lead screen cannot be flexibly adjusted according to actual protection needs. Utility Model Content

[0004] This utility model provides a radiation protection lead screen that can effectively solve the problems in actual radioactive workplaces, such as hospital radiology departments and nuclear industry laboratories, where the spatial layout and equipment placement are often irregular. Traditional fixed-size lead screens are difficult to fully adapt to these complex environments, easily creating blind spots in protection, and their width cannot be adjusted. This leads to problems such as the inability to flexibly adjust the width of the lead screen according to actual protection needs.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] A radiation protection lead screen includes a main lead screen, with rotating shafts rotatably connected to the inner walls of the left and right sides of the main lead screen, and side lead screens rotatably connected to the outer walls of the upper and lower sides of the rotating shafts. Telescopic lead screens are slidably connected to the inner walls of the two side lead screens on opposite sides, and several casters are fixedly connected to the front and rear sides of the main lead screen and the side lead screens.

[0007] A further improvement of the present invention is that: the main lead screen includes a main protective lead screen, an observation frame extending to the rear outside is provided on the front side of the main protective lead screen, lead glass is fixedly connected to the inner wall of the observation frame, arc-shaped blocks are fixedly connected to the middle of the left and right sides of the main protective lead screen, semi-circular blocks are fixedly connected to the upper and lower sides of the left and right sides of the main protective lead screen, protective sealing strips are fixedly connected to the front and rear outer walls of the left and right sides of the main protective lead screen, and a circular hole extending to the lower outside is provided on the side of the arc-shaped block away from the semi-circular block.

[0008] A further improvement of the present invention is that the rotating shaft includes two cylinders, and threaded grooves are provided on the upper and lower outer walls of the cylinders. Nuts are threadedly connected to the threaded grooves, and the outer wall of the threaded grooves is rotatably connected to the inner wall of the circular hole.

[0009] A further improvement of this utility model is that: the side lead screen includes two side protective lead screens, each of the two side protective lead screens having a square groove on its opposite side, and a square groove II fixedly connected to the upper and lower sides of the inner wall of each square groove; an arc-shaped block II fixedly connected to the upper and lower sides of the opposite surfaces of the two side protective lead screens, and a circular hole II extending to the lower outside of the arc-shaped block II; the inner wall of the circular hole II is rotatably connected to the outer wall of the cylinder; the front and rear outer walls of the side protective lead screens closest to the main protective lead screen are fixedly connected to the inner walls of the two adjacent protective sealing strips on the side away from the main protective lead screen; and a square fixing block is fixedly connected to the upper surface of each of the two side protective lead screens on its opposite side, with screws threaded onto the inner wall of the square fixing block.

[0010] A further improvement of this utility model is that: the telescopic lead screen includes two inner telescopic protective lead screens, each of which has a handle fixedly connected to the side of the two inner telescopic protective lead screens that are far apart from each other; the upper and lower sides of the inner telescopic protective lead screens near the opposite side of the square groove are provided with semi-circular grooves; the front and rear sides of the upper and lower sides of the inner telescopic protective lead screens positioned in the semi-circular grooves are fixedly connected with square fixing blocks two; the front and rear sides of the inner walls of the semi-circular grooves and the square fixing blocks two are rotatably connected with rollers; the outer wall of the inner telescopic protective lead screens is slidably connected to the inner wall of the square grooves; and the outer wall of the rollers is rollingly connected to the inner wall of the square groove two.

[0011] A further improvement of the present invention is that the universal wheel includes several oblique support columns, and a universal wheel is fixedly connected to the bottom of the oblique support columns. The opposite surfaces of the several front and rear oblique support columns are all fixedly connected to the bottom front and rear sides of the main protective lead screen and the side protective lead screen.

[0012] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0013] By rotating the side protective lead screen, the arc-shaped block two and the cylinder are rotated and adjusted to a suitable angle. Then, the nut is tightened through the threaded groove to fix it. The protective sealing strip can seal and protect against tiny gaps. In the examination room of the medical radiology department, when it is necessary to protect irregularly shaped examination equipment or patient positions, the shape of the lead screen can be flexibly adjusted to better adapt to different radiation sources and protection scenarios. It can closely surround the radiation source and work area to provide protection, effectively preventing radiation from leaking outside the protected area, and greatly improving the accuracy and comprehensiveness of protection.

[0014] By grasping the handle and pulling, the inner telescopic protective lead screen slides against the square groove, causing the rollers to roll against the inner wall of the square groove and slide out. After adjusting to the appropriate width, tighten the screws to rotate them with the threads of the square fixing block, pressing against the upper outer wall of the inner telescopic protective lead screen for fixation. The inner telescopic protective lead screen allows the width of the lead screen to be adjusted according to the specific radiation source range. When using low-power radiation equipment, the inner telescopic protective lead screen can be stored away to reduce space occupation; while when facing high-power, wide-radiation equipment, such as large medical linear accelerators, stretching the inner telescopic protective lead screen can expand the protective width, providing sufficient shielding area to ensure the safety of personnel and the surrounding environment.

There is a square groove 34, and square grooves 35 are fixedly connected to the upper and lower sides of the inner wall of the square groove 34. Arc-shaped blocks 32 are fixedly connected to the upper and lower sides of the opposite surfaces of the two side protective lead screens 31. A circular hole 33 is opened above the arc-shaped block 32, which extends to the lower outside. The inner wall of the circular hole 33 is rotatably connected to the outer wall of the cylinder 21. The front and rear outer walls of the side protective lead screens 31 near the main protective lead screen 11 are fixedly connected to the inner walls of the two adjacent protective sealing strips 17 away from the main protective lead screen 11. Square fixing blocks 36 are fixedly connected to the upper sides of the two side protective lead screens 31 away from each other. Screws 37 are threadedly connected to the inner walls of the square fixing blocks 36. The universal wheel 5 includes several oblique support columns 51.

[0029] The telescopic lead screen 4 has an adjustable width. In use, it is pulled by grasping the handle 42, causing the inner telescopic protective lead screen 41 to slide against the square groove 34. This allows the roller 45 to roll against the inner wall of the square groove 35 and slide out. After adjusting to the appropriate width, the screw 37 is tightened to rotate with the screw thread of the square fixing block 36, thus pressing against the upper outer wall of the inner telescopic protective lead screen 41 for fixation. The inner telescopic protective lead screen 41 allows the width of the lead screen to be adjusted according to the specific radiation source range. When using low-power radiation equipment, the inner telescopic protective lead screen 41 can be stored away to reduce space occupation. However, when facing high-power, large-radiation-range equipment, such as large medical linear accelerators, extending the inner telescopic protective lead screen 41 can expand the protective width, providing sufficient shielding area to ensure the safety of personnel and the surrounding environment.

[0030] The working principle of this radiation protection lead screen is explained in detail below: The main lead screen 1, the rotating shaft column 2, and the side lead screen 3 can be adjusted in angle. During use, the side protective lead screen 31 is rotated to make the arc-shaped block 32 and the cylinder 21 rotate and adjust to a suitable angle. Then, the nut 23 is tightened through the threaded groove 22 for fixation. The protective sealing strip 17 can seal and protect against tiny gaps. In the examination room of the medical radiology department, when it is necessary to protect irregularly shaped examination equipment or patient positions, the shape of the lead screen can be flexibly adjusted to better adapt to different radiation sources and protection scenarios. It can closely surround the radiation source and the work area for protection, effectively preventing radiation from leaking outside the protected area, and greatly improving the accuracy and comprehensiveness of protection.

[0031] The telescopic lead screen 4 has an adjustable width. In use, it is pulled by grasping the handle 42, causing the inner telescopic protective lead screen 41 to slide against the square groove 34. This allows the roller 45 to roll against the inner wall of the square groove 35 and slide out. After adjusting to the appropriate width, the screw 37 is tightened to rotate with the screw thread of the square fixing block 36, thus pressing against the upper outer wall of the inner telescopic protective lead screen 41 for fixation. The inner telescopic protective lead screen 41 allows the width of the lead screen to be adjusted according to the specific radiation source range. When using low-power radiation equipment, the inner telescopic protective lead screen 41 can be stored away to reduce space occupation. However, when facing high-power, large-radiation-range equipment, such as large medical linear accelerators, extending the inner telescopic protective lead screen 41 can expand the protective width, providing sufficient shielding area to ensure the safety of personnel and the surrounding environment.

[0032] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
