Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of nursing screen devices, and in particular to a radiation protection nursing screen for radiation nursing. Background Technology
[0002] Radiation therapy is a common cancer treatment method in modern medicine, and radiation protection screens for radiation care are essential equipment specifically designed to protect medical personnel during radiation therapy. This equipment aims to reduce the impact of radiation on medical staff and ensure their safety. A typical radiation protection screen consists of a scissor lift, casters, a hoisting assembly, and lead plates. The casters are mounted at the bottom of the scissor lift for easy movement, and the hoisting assembly is mounted at the top of the scissor lift. The hoisting rod of the hoisting assembly extends from one side of the scissor lift to hoist the lead plates. The following drawbacks have been observed during use:
[0003] 1. The lead plates on the existing suspended screens are fixedly connected to the hoisting components, making them inconvenient to replace. This results in the protective dimensions being fixed and unable to be adjusted according to the actual situation.
[0004] 2. Since lead plates have a certain weight, the larger the area of the lead plate, the heavier it is. If the center of gravity of the device remains unchanged when changing lead plates of different sizes, the device may become unstable.
[0005] 3. Since the hanging rod extends outwards, it tends to occupy most of the horizontal space when the hanging screen is not in use. Utility Model Content
[0006] The purpose of this invention is to provide a radiation protection nursing screen for radiation care, which can solve the problems of existing radiation protection nursing screens that cannot replace lead plates of different sizes and the horizontal space occupied by the hanging rods.

The center of gravity adjustment block is screwed onto the screw section between the receiving plate and the supporting pad block. A motor for driving the screw to rotate is provided on the outside of the receiving plate.
[0009] In some possible implementations, the bottom of the center of gravity adjustment block is provided with a slider, and the top of the scissor lift is provided with a slide groove that slides with the slider, the slide groove being located between the receiving plate and the support pad.
[0010] In some possible implementations, the clamping assembly includes an adjustment box fixedly mounted at the extended end of the boom, a gear rotatably mounted inside the adjustment box, and racks meshing with the gear on both the upper and lower sides of the gear inside the adjustment box, the racks slidingly connected within the adjustment box, a clamping block fixedly mounted at the outer end of the racks, and a second motor for driving the gear to rotate fixedly mounted on one side of the adjustment box.
[0011] In some possible implementations, the side of the rack opposite to the adjusting box is provided with a slider two, and the adjusting box is provided with a corresponding groove two that cooperates with the slider two.
[0012] In some possible implementations, the caster wheel is provided with a locking mechanism.
[0013] In some possible implementations, the connecting clip is located on top of the center of gravity adjustment block.
[0014] By adopting the above technical solution, this utility model has the following beneficial effects compared with the prior art:
[0015] 1. A clamping assembly is fixedly installed at the extended end of the hanging rod of this utility model.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the indicated position or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0025] like Figures 1-3The embodiment shown includes a scissor lift 1, with four casters 2 installed at its bottom for easy movement of the suspended screen. Each caster 2 has a locking mechanism to brake its rotation. A lifting assembly is mounted on top of the scissor lift 1, which holds a lead plate 7. The lifting assembly includes a center-of-gravity adjustment component 3 mounted on top of the scissor lift 1 and a support block 4 fixedly mounted on one side of the top of the scissor lift 1. A lifting rod 5 is hinged to the center-of-gravity adjustment component 3 via a connecting clamp. The connecting clamp allows the lifting rod 5 to rotate 180 degrees and retract in the opposite direction. The support block 4 supports the lifting rod 5 when it extends outwards. The center-of-gravity adjustment component 3 includes components fixedly mounted on the scissor lift 1. A receiving plate 301 is located on the opposite side of the top of the support pad 4. This receiving plate is connected to the support pad 4 via a lead screw 302. A center-of-gravity adjusting block 304 is fitted onto the lead screw section between the receiving plate 301 and the support pad 4. The center-of-gravity adjusting block 304 has a threaded hole for the lead screw 302 to rotate. A motor 303 for driving the lead screw 302 is located on the outside of the receiving plate 301. The center-of-gravity adjusting block 304 is slidably connected to the top of the scissor lift 1. A slider 8 is located at the bottom of the center-of-gravity adjusting block 304. A sliding groove 9, which cooperates with the slider 8, is located at the top of the scissor lift 1 between the receiving plate 301 and the support pad 4. A connecting clip 12 is located at the top of the center-of-gravity adjusting block 304. Because the threaded hole is rotatably connected to the lead screw 302, the position of the center-of-gravity adjusting block 304 can be adjusted, thereby adjusting the position of the lifting rod 5 and adjusting the center of gravity of the device according to the weight of the lead plate 7. Figure 4 As shown, a clamping assembly 6 is fixedly installed at the extended end of the boom 5. A lead plate 7 is clamped inside the clamping assembly 6 to isolate radiation. The clamping assembly 6 includes an adjustment box 601 fixedly installed at the extended end of the boom 5. A gear 602 is rotatably installed inside the adjustment box 601. A rack 603 is installed on both the upper and lower sides of the gear 602 inside the adjustment box 601. The gear 602 and the two racks 603 are meshed with each other. The racks 603 are slidably connected to the adjustment box 601. A slider 2 10 is installed on the rack 603. A sliding groove 2 11 is installed inside the adjustment box 601 to slide with the slider 2 10. The outer ends of the two racks 603 extend out of the adjustment box and are fixedly mounted with clamping blocks 604. The lead plate 7 is clamped between the two clamping blocks 604. A motor 2 605 that drives the gear 602 to rotate is fixedly installed on one side of the adjustment box 601. Since the rack 603 is meshed with the gear 602, the distance between the two clamping blocks 604 can be adjusted to clamp lead plates 7 of different sizes.
[0026] The working principle of this utility model:
[0027] When a pendant screen is needed, it can be used as follows: Figure 2The device is moved to a suitable position via the casters 2. Once in the desired position, the locking mechanism is activated to brake the casters and prevent movement. The boom 5 can then be rotated 180° around the connecting clamp. The position of the center-of-gravity adjusting block 304 is adjusted according to the weight of the lead plate 7. Starting motor 1 303 rotates the lead screw 302, causing the center-of-gravity adjusting block 304 to move, thus moving the boom 5 and adjusting the device's center of gravity. After adjustment, motor 1 303 is turned off. The lead plate 7 is then placed between the two clamping blocks 604. Starting motor 2 605 rotates the gear 602, causing the two racks 603 to move in opposite directions, thus moving the two clamping blocks 604 towards the lead plate 7 to clamp it. The height of the lead plate 7 can be adjusted using the scissor lift 1.
[0028] 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.
