Description

Technical Field

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

[0002] As a medical device, radiation protection barrier screens play a crucial role in diagnostic examinations using radiation. Given the potential hazards of radiation to the human body, barrier screens effectively block radiation and reduce harm to those around them.

[0003] However, existing radiation shielding screens of this type have some drawbacks in use. For example, Chinese patent CN205230607U discloses a radiation shielding screen, including a screen body, a thickened support leg on the lower side of the screen body, a main radiation shielding plate on the upper side of the thickened support leg, an observation window on the main radiation shielding plate, a radiation-proof observation glass inside the observation window, a glass sliding handle on the radiation-proof observation glass, a lighting control panel on the right side of the observation window, a lighting switch on the lighting control panel, a switch indicator light below the lighting switch, and a placement plate hinge below the observation window, with a foldable item placement plate mounted on the placement plate hinge. In the existing technology, the main radiation shielding plate and the auxiliary radiation shielding plate on the side of the screen are hinged together by the hinge; however, gaps inevitably exist at the connection point, which can lead to the leakage of radioactive materials, posing a threat to the health of people in the surrounding area.

[0004] To address this issue, we have developed a new type of portable radiation protection barrier screen, designed to effectively solve the problem of radioactive material leakage caused by gaps in the connection seams of the screen panels in existing technologies, and to provide a more reliable and safer solution for radiation protection in medical environments. Utility Model Content

[0005] The purpose of this invention is to provide a movable radiation protection barrier screen to solve the above-mentioned technical problems existing in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a movable radiation protection barrier screen, comprising a main radiation shield plate with wheels at the bottom, and an auxiliary radiation shield plate hinged to at least one vertical side of the main radiation shield plate via a connecting component. The auxiliary radiation shield plate can rotate within a certain range around the hinge axis, and a corner protection device is provided on the outer side of the hinge joint between the main radiation shield plate and the auxiliary radiation shield plate.

[0007] Furthermore, the corner protection device includes two parallel arc rods and a soft lead blanket placed outside the hinge joint between the main anti-radiation plate and the auxiliary anti-radiation plate.

[0008] The center of the arc of the arc rod is on the same straight line as the central axis of the hinge shaft. One end of the arc rod is fixedly connected to the main anti-ballistic plate, and the other end passes through the auxiliary anti-ballistic plate and extends to its outside. The auxiliary anti-ballistic plate has an arc-shaped through hole adapted to the arc rod in its thickness direction. When the angle of the auxiliary anti-ballistic plate is adjusted, the auxiliary anti-ballistic plate moves along the arc of the arc rod.

[0009] The soft lead blanket has fixed parts on the left and right sides and a movable part in the middle. The fixed part on one side of the soft lead blanket is fixed to the outer wall of the main anti-radiation plate, and the fixed part on the other side is fixed to the outer wall of the auxiliary anti-radiation plate. The upper and lower ends of the movable part are slidably connected to two arc rods. When the auxiliary anti-radiation plate rotates, the soft lead blanket is guided by the arc rods to contract or expand.

[0010] Furthermore, both the main and auxiliary anti-radiation plates are made of hard lead.

[0011] Furthermore, the auxiliary anti-radiation plate can rotate between 0-90° around the hinge axis;

[0012] When the main anti-ballistic plate is connected to an auxiliary anti-ballistic plate, the angle of the auxiliary anti-ballistic plate can be adjusted so that the connection between the two is in an L-shape or an I-shape.

[0013] When the main anti-ballistic plate is connected to two auxiliary anti-ballistic plates, the angles of the two auxiliary anti-ballistic plates can be adjusted to make the connection of the three plates into an L-shaped, I-shaped, or U-shaped configuration.

[0014] Furthermore, the connecting assembly includes a convex side plate disposed on the vertical side of the main fire shield plate, the convex side plate having multiple grooves along its length direction, the hinge shaft being vertically installed in the grooves, and the auxiliary fire shield plate having a connecting strip at the position corresponding to the grooves, the end of the connecting strip away from the auxiliary fire shield plate being rotatably mounted on the hinge shaft, thereby realizing the hinge connection between the main fire shield plate and the auxiliary fire shield plate.

[0015] Furthermore, a limiting device is provided at the waist position outside the hinge between the main anti-ballistic plate and the auxiliary anti-ballistic plate.

[0016] Furthermore, the limiting device consists of an arc-shaped telescopic rod and a limiting bolt. The center of the arc of the arc-shaped telescopic rod is on the same straight line as the central axis of the hinge shaft. The arc-shaped telescopic rod includes a fixed rod and a movable rod. The fixed rod has a channel inside for adjusting the extension and retraction of the movable rod. The limiting bolt is threaded to the fixed rod, and its lower end can extend into the channel to press against the movable rod.

[0017] Furthermore, a telescopic fireproof plate is telescopically connected to the side of the auxiliary fireproof plate away from the main fireproof plate. The auxiliary fireproof plate has a cavity inside for the telescopic fireproof plate to perform telescopic movement. A positioning device for controlling the extension length of the telescopic fireproof plate is provided on the plate of the auxiliary fireproof plate away from the main fireproof plate.

[0018] Furthermore, the positioning device is a positioning bolt, which is threadedly connected to the auxiliary anti-shoot plate, with one end extending into the cavity to press and limit the telescopic anti-shoot plate.

[0019] Compared with existing technologies, the above technical solution has the following advantages:

[0020] 1. It can solve the problem of leakage through gaps. By filling the gaps at the hinge of the main radiation shield and the auxiliary radiation shield with soft lead blankets in the corner protection device, it can effectively block the leakage of radioactive materials and protect the health of the surrounding personnel.

[0021] 2. It has flexible and versatile protection configurations. The main radiation shield and the auxiliary radiation shield can be combined into L-shaped, U-shaped or I-shaped configurations to meet the radiation protection needs of different scenarios and has strong adaptability.

[0022] 3. The protection range is adjustable. With the setting of telescopic protective plates and the cooperation of positioning devices, the protection range can be adjusted according to actual needs, which increases the flexibility and practicality of the device.

[0023] In summary, the screen proposed in this invention can effectively prevent radioactive materials from leaking from the hinge points, and also has a flexible and versatile protective form. It is easy to use and highly practical, providing a more reliable, safe, and convenient solution for radiation protection in medical environments. Attached Figure Description

Detailed Implementation

[0034] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this utility model.

[0035] To address the problems existing in the prior art, this utility model provides a movable radiation protection barrier screen, which will be described in detail below with reference to the accompanying drawings.

[0036] Example 1

[0037] See Figures 1-5As shown, the technical solution adopted in this specific embodiment is: a movable radiation protection barrier screen, including a main radiation shield 1, with multiple casters 11 mounted on the bottom end of the main radiation shield 1. Preferably, the casters 11 are omnidirectional wheels. An auxiliary radiation shield 2 is hinged to one side of the main radiation shield 1, or an auxiliary radiation shield 2 is hinged to both sides of the main radiation shield 1. The auxiliary radiation shield 2 can rotate around the hinge axis 31, with a rotation angle range of 0-90°. The bottom end of the auxiliary radiation shield 2 is equipped with casters 11. In practical use, by manually adjusting the angle of the auxiliary fire shield 2, the main fire shield 1 and the auxiliary fire shield 2 can be combined to form different shapes: when one auxiliary fire shield 2 is provided, adjusting the angle of the auxiliary fire shield 2 can make the main fire shield 1 and the auxiliary fire shield 2 form an L-shape or an I-shape; when two auxiliary fire shield 2 are provided, the angles of the auxiliary fire shield 2 on both sides can be adjusted separately. For example, when both auxiliary fire shield 2 are rotated toward the main fire shield 1 and perpendicular to the main fire shield 1, the three form a U-shape, which can form a relatively closed protective area. Alternatively, one auxiliary fire shield 2 can be rotated toward the main fire shield 1 and perpendicular to the main fire shield 1, and the other auxiliary fire shield 2 can be adjusted to be on the same plane as the main fire shield 1. At this time, the three form an L-shape. Alternatively, both auxiliary fire shield 2 can be adjusted to be on the same plane as the main fire shield 1, and the three form an I-shape, which is convenient for use under linear protection requirements. This connection and adjustment method gives the screen a flexible and versatile protective form, which can be quickly adjusted according to actual usage needs, effectively meeting the radiation protection requirements in different scenarios.

[0038] It should be specifically noted that both the main anti-ballistic plate 1 and the auxiliary anti-ballistic plate 2 are made of rigid lead. They are connected by a connecting assembly 3, which includes a convex side plate 32 disposed on the vertical side of the main anti-ballistic plate 1. The convex side plate 32 has multiple grooves 321 along its length, and the hinge shaft 31 is vertically installed within these grooves 321. Simultaneously, the auxiliary anti-ballistic plate 2 has a connecting strip 33 at the corresponding groove 321 position. The end of the connecting strip 33 away from the auxiliary anti-ballistic plate 2 is rotatably mounted on the hinge shaft 31, thereby achieving a hinged connection between the main anti-ballistic plate 1 and the auxiliary anti-ballistic plate 2, and allowing the auxiliary anti-ballistic plate 2 to rotate relative to the main anti-ballistic plate 1 within a certain angle range.

[0039] It should be specifically noted that a corner protection device 4 is provided on the outside of the hinge joint between the main radiation shield 1 and the auxiliary radiation shield 2. The corner protection device 4 is used to fill the gap caused by the structural connection between the hinge joint of the main radiation shield 1 and the auxiliary radiation shield 2, further enhancing the protective performance of the entire barrier screen, effectively blocking the leakage of radioactive materials from the connection gap, and protecting the health of people in the surrounding area.

[0040] Specifically, the corner protection device 4 consists of two parallel arc rods 41 and a soft lead blanket 42, with the soft lead blanket 42 positioned outside the hinge between the main anti-ballistic plate 1 and the auxiliary anti-ballistic plate 2. The center of arc of each arc rod 41 is aligned with the central axis of the hinge shaft 31 to ensure precise fit. One end of each arc rod 41 is fixedly connected to the outer wall of the main anti-ballistic plate 1, while the other end passes through the auxiliary anti-ballistic plate 2 and extends to its exterior. To facilitate the smooth assembly of the arc rod 41 and the auxiliary anti-ballistic plate 2, the auxiliary anti-ballistic plate 2 has an arc-shaped through-hole 21 in its thickness direction, matching the shape of the arc rod 41. This through-hole allows the arc rod 41 to pass through stably and maintain the continuity of the overall structure. The diameter of the arc-shaped through-hole 21 is slightly larger than the outer diameter of the arc rod 41, ensuring that the arc rod 41 can pass through smoothly and move within a certain range. Furthermore, the wall of the arc-shaped through-hole 21 is smoothed to reduce friction. When the angle of the auxiliary radiation shield 2 is adjusted, the auxiliary radiation shield 2 can move along the arc of the arc rod 41, achieving flexible angle adjustment. The soft lead blanket 42 has a fixed part 421 on the left and right sides and a movable part 422 in the middle. One fixed part 421 is fixed to the outer wall of the main radiation shield 1, and the other fixed part 421 is fixed to the outer wall of the auxiliary radiation shield 2. The upper and lower ends of the movable part 422 are slidably connected to the two arc rods 41 respectively. When the auxiliary radiation shield 2 rotates, the soft lead blanket 42 is guided by the arc rods 41 to contract or expand, thereby effectively filling the connection gap between the main radiation shield 1 and the auxiliary radiation shield 2 and enhancing the radiation protection effect.

[0041] Example 2

[0042] See Figures 6-7 As shown, the difference between this embodiment and Embodiment 1 is that a limiting device 5 is provided at the waist position outside the hinge between the main anti-radiation plate 1 and the auxiliary anti-radiation plate 2. This limiting device 5 consists of an arc-shaped telescopic rod 51 and a limiting bolt 52. The arc center of the arc-shaped telescopic rod 51 is collinear with the central axis of the hinge shaft 31. It is located outside the corner protection device 4, and the radius of the arc-shaped telescopic rod 51 is larger than the radius of the arc rod 41, allowing the soft lead blanket 42 to be stored inside. The arc-shaped telescopic rod 51 includes a fixed rod 511 and a movable rod 512, both of which are arc-shaped. The fixed rod 511 has an internal channel 5111 for the movable rod 512 to extend and retract. The limiting bolt 52 is threadedly connected to the fixed rod 511, and its lower end can extend into the channel 5111. By pressing against the movable rod 512, the length of the arc-shaped telescopic rod 51 is limited and fixed.

[0043] Example 3

[0044] See Figure 8As shown, this embodiment differs from Embodiments 1 and 2 in that a telescopic fire-resistant plate 6 is connected to the side of the auxiliary fire-resistant plate 2 away from the main fire-resistant plate 1, and the two are connected by a telescopic connection. Specifically, the auxiliary fire-resistant plate 2 has a dedicated cavity (not shown in the figure) for the telescopic fire-resistant plate 6 to extend and retract. Simultaneously, a positioning device 22 is provided on the plate of the auxiliary fire-resistant plate 2 away from the main fire-resistant plate 1. This positioning device 22 is in the form of a positioning bolt, which is threadedly connected to the auxiliary fire-resistant plate 2. One end of the positioning bolt can extend into the cavity to tighten and limit the telescopic fire-resistant plate 6, thereby controlling the extension length of the telescopic fire-resistant plate 6. Furthermore, the bottom of the telescopic fire-resistant plate 6 is connected to wheels 11 for easy movement of the entire device; a handle 61 is installed on the side of the telescopic fire-resistant plate 6 for easy operation by personnel to extend or retract it.

[0045] Working principle: When using this movable radiation protection barrier screen, the auxiliary radiation shield 2 can be manually adjusted to rotate around the hinge axis 31 to the required angle, forming an L-shape, U-shape, or I-shape with the main radiation shield 1 to adapt to different protection scenarios. At the same time, the soft lead blanket 42 of the corner protection device 4 retracts or extends under the guidance of the arc rod 41 as the auxiliary radiation shield 2 rotates, filling the gap at the hinge between the main radiation shield 1 and the auxiliary radiation shield 2. After adjusting the protection configuration, the position of the auxiliary radiation shield 2 can be fixed using the limiting device 5. If it is necessary to expand the protection range, the telescopic radiation shield 6 can be stretched to a suitable length and limited by the positioning device 22. The wheels 11 at the bottom of the entire device facilitate movement to the designated position, and the handle 61 on the side of the telescopic radiation shield 6 facilitates the operator's stretching or retraction operation.
