Description

Technical Field

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

[0002] Radiation protection is crucial in the daily work of a radiology department. Medical staff, patients, and other related personnel need effective protective measures to avoid harm from radiation. Lead shields, as a commonly used protective device, function to block the propagation of radiation, reduce the impact of radiation on the human body, and thus protect the health and safety of personnel.

[0003] Traditional protective lead screens typically employ fixed structures or simple splicing combinations. Their main protective panel is a single, fixed unit. In special scenarios, such as when space is limited and protective lead screens need to be stored, their inability to change size and shape results in them occupying significant space, making storage and organization inconvenient and hindering hospital space management. Furthermore, traditional protective lead screens have shortcomings in adjusting the protective angle. Some traditional lead screens have a fixed protective angle and cannot be flexibly flipped to meet actual usage needs; even those that can be flipped to a certain extent often lack a stable and reliable fixing method after flipping, potentially shifting due to slight collisions or shaking during use, thus affecting the protective effect. Utility Model Content

[0004] (I) Technical Issues

[0005] The present invention aims to provide a novel and functional protective lead screen, which solves the problem of inconvenient storage of traditional protective lead screens, and improves the poor flip-adjustment and fixation performance of traditional protective lead screens.

[0006] (II) Technical Content

[0007] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows: a radiation protection lead screen for radiology, including a main protective plate, a base fixedly provided at the bottom of the main protective plate, a cavity penetrating the left and right sides inside the main protective plate, and extended protective plates slidably provided at both ends of the cavity. A bidirectional driving mechanism for driving the two extended protective plates to move closer or further apart is fixedly provided on the rear side of the main protective plate. A flip plate is rotatably connected to the outer end of the extended protective plate via a rotating shaft. The rotating shaft is fixedly provided at the upper and lower ends of the flip plate and rotatably connected to the extended protective plate. A first chuck is fixedly provided at the bottom of the flip plate, and a second chuck is provided with clearance fit on the outer side of the rotating shaft. A guide rod is fixedly provided at the bottom of the second chuck. The guide rod passes through the bottom of the extended protective plate and is slidably connected to the extended protective plate. A fastening bolt is threadedly connected to the bottom of the extended protective plate, and the upper end of the fastening bolt is rotatably connected to the bottom of the second chuck.

[0008] Furthermore, the bidirectional drive mechanism includes a bidirectional lead screw rotatably mounted on the back of the main protective plate, with a turntable fixedly mounted at one end of the bidirectional lead screw, and also includes sliders fixedly mounted on the rear sides of the two extended protective plates. The bidirectional lead screw passes through the two sliders and is threadedly connected to the sliders. The rear side of the main protective plate is provided with a strip-shaped through groove for the sliders to pass through and move.

[0009] Furthermore, the main protective plate has a track groove on its inner bottom surface, and several rollers are rotatably provided at the bottom of the extended protective plate, with the rollers rolling inside the track groove.

[0010] Furthermore, the main protective plate has a groove on its inner top surface, and a sliding strip that matches and slides on the top of the extended protective plate is fixedly provided.

[0011] (III) Technical Effects

[0012] The advantages of this utility model compared with the prior art are as follows:

[0013] 1. The radiation protection lead screen for radiology departments of this utility model has a cavity inside the main protective plate, and an extension protective plate is slidably connected inside the cavity. When storage is required, the extension protective plate can be slid into the cavity of the main protective plate, which effectively reduces the overall footprint of the lead screen and makes it convenient to store and organize in the limited space of the hospital. This solves the problem of traditional protective lead screens being difficult to store due to their fixed size.

[0014] 2. The outer end of the extended protective plate is connected to a flip plate via a rotating shaft. A first chuck is installed at the bottom of the flip plate, and a second chuck is fitted with the outer side of the rotating shaft. Together with a guide rod and fastening bolts, this allows for flexible and stable angle adjustment and fixation of the flip plate. Medical personnel can adjust the angle of the flip plate according to the actual radiation irradiation direction and protection requirements, and then securely fix the flip plate with the fastening bolts to prevent angle changes due to collisions or shaking during use.

[0015] 3. The bidirectional lead screw and slider in the bidirectional drive mechanism, as well as the track groove on the bottom surface of the main protective plate and the rollers on the bottom of the extended protective plate, and the sliding groove and slider on the top surface, make the extended protective plate move more smoothly and steadily, reducing friction and wear between components. This not only improves the service life of the lead screen, but also ensures the stability of the entire structure during frequent use and adjustment. Attached Figure Description

[0029] The present invention will now be described in further detail with reference to the accompanying drawings.

[0030] Combined with appendix Figure 1 To be continued Figure 10 A radiation shielding lead screen for radiology includes a main shielding plate 1, a base 3 fixedly mounted on the bottom of the main shielding plate 1, and a cavity 2 extending through both sides inside the main shielding plate 1. Extended shielding plates 4 are slidably mounted on both ends of the cavity 2. A bidirectional drive mechanism for driving the two extended shielding plates 4 to move closer or further apart is fixedly mounted on the rear side of the main shielding plate 1. A flip plate 5 is rotatably connected to the outer end of each extended shielding plate 4 via a rotating shaft 6. The rotating shaft 6 is fixedly mounted on the upper and lower ends of the flip plate 5 and rotatably connected to the extended shielding plate 4. A first chuck 7 is fixedly mounted at the bottom of the flip plate 5, and a second chuck 8 is fitted with the outer side of the rotating shaft 6 with clearance. A guide rod 9 is fixedly mounted at the bottom of the second chuck 8, passing through the bottom of the extended shielding plate 4 and slidably connected to it. A fastening bolt 10 is threadedly connected to the bottom of the extended shielding plate 4, and the upper end of the fastening bolt 10 is rotatably connected to the bottom of the second chuck 8.

[0031] In this embodiment, as a preferred technical solution, the bidirectional drive mechanism includes a bidirectional lead screw 11 rotatably disposed on the back of the main protective plate 1, a turntable 12 fixedly disposed at one end of the bidirectional lead screw 11, and a slider 13 fixedly disposed on the rear side of the two extended protective plates 4. The bidirectional lead screw 11 passes through the two sliders 13 and is threadedly connected to the sliders 13. The rear side of the main protective plate 1 is provided with a strip-shaped through groove 14 for the sliders 13 to pass through and move.

[0032] In this embodiment, as a preferred technical solution, the bottom surface of the main protective plate 1 is provided with a track groove 15, the bottom of the extended protective plate 4 is provided with a plurality of rollers 16, the rollers 16 roll inside the track groove 15, the top surface of the main protective plate 1 is provided with a sliding groove 17, and the top of the extended protective plate 4 is fixedly provided with a sliding strip 18 that matches and slides with the sliding groove 17.

[0033] The working principle of this radiation shielding lead screen for radiology is as follows: When the bidirectional lead screw 11 in the bidirectional drive mechanism rotates, it is threadedly connected to the slider 13 fixed on the rear side of the extended shielding plate 4. Since the slider 13 is restricted to linear motion by the strip groove 14 on the rear side of the main shielding plate 1, the rotation of the bidirectional lead screw 11 causes the two extended shielding plates 4 to move closer or further apart within the cavity 2 of the main shielding plate 1, thereby adjusting the shielding area. The flip plate 5 at the outer end of the extended shielding plate 4 is rotatably connected to the extended shielding plate 4 via a rotating shaft 6, allowing for angle adjustment. The first chuck 7 at the bottom of the flip plate 5 and the second chuck 8 outside the rotating shaft 6, along with the guide rod 9 and the fastening bolts 10 at the bottom of the extended shielding plate 4, can be fixed after the flip plate 5 is adjusted to a suitable angle, ensuring its stable position and providing reliable radiation protection. The track groove 15 on the bottom surface of the main protective plate 1 and the roller 16 at the bottom of the extended protective plate 4, as well as the sliding groove 17 on the top surface of the main protective plate 1 and the sliding strip 18 at the top of the extended protective plate 4, cooperate with each other to ensure the stability and accuracy of the extended protective plate 4 during movement, which helps the entire lead screen to stably play its role in radiation protection.

[0034] The working process of this utility model of a radiation protection lead screen for radiology is as follows:

[0035] 1. Initial condition check: Before use, first check whether all parts of the protective lead screen are intact, ensure that the turntable 12 of the bidirectional screw 11 can rotate flexibly, the extension protective plate 4 slides smoothly in the cavity 2, the rotating shaft 6 of the flip plate 5 rotates flexibly, and the fastening bolts 10 are not loose, etc., to ensure that the lead screen is in a normal usable state.

[0036] 2. Adjustment of protection area: According to the actual size of the area to be protected, rotate the turntable 12 at one end of the bidirectional lead screw 11 to make the bidirectional lead screw 11 rotate, which drives the slider 13 to move in the strip groove 14, thereby making the two extended protective plates 4 move closer or further apart in the cavity 2 to adjust to a suitable protection area to meet the needs of radiation protection range in different scenarios.

[0037] 3. Adjustment of the angle of the flip plate: After the position of the extended protective plate 4 is determined, the flip plate 5 is rotated according to the direction of the radiation source and the actual protection angle requirements, so that it rotates around the rotating shaft 6 to a suitable angle, and is initially positioned by the cooperation of the first chuck 7 and the second chuck 8.

[0038] 4. Fixing the flip plate: After adjusting the flip plate 5 to the required angle, tighten the fastening bolt 10 at the bottom of the extension protective plate 4. The upper end of the fastening bolt 10 rotates to the bottom of the second chuck 8, thereby driving the second chuck 8 to move upward and contact and lock with the first chuck 7. The surfaces of the second chuck 8 and the first chuck 7 that are in contact are provided with serrated protrusions, thereby fixing the angle of the flip plate 5 and ensuring that the flip plate 5 will not rotate due to external force during use, thus ensuring the stability and reliability of radiation protection.

[0039] 5. Storage after use: After use, if it is necessary to store the protective lead screen, first loosen the fastening bolt 10, turn the flip plate 5 back to the initial position so that it fits against the extended protective plate 4, and then turn the turntable 12 in the opposite direction so that the bidirectional screw 11 drives the extended protective plate 4 to slide into the cavity 2 of the main protective plate 1 until the extended protective plate 4 is completely stored in the cavity 2, reducing the space occupied by the lead screen and making it convenient for storage and organization.

[0040] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
