Description

Technical Field

[0001] This utility model relates to the field of screens, and more particularly to a radiation protection screen. Background Technology

[0002] A screen, a type of furniture used to block the wind inside traditional Chinese buildings, was originally called "di" and was an exclusive item for the emperor, hence the name "screen to block the wind." As an important part of traditional furniture, the screen has a long history. Screens are generally placed in a prominent position in the room, serving to divide space, beautify the room, block the wind, and harmonize the space. They complement classical furniture, creating a harmonious and integrated whole, forming an inseparable part of Chinese home decoration, and presenting a harmonious and tranquil beauty.

[0003] In the medical field, with the widespread application of radiological diagnostics (such as X-ray examinations and CT scans) and radiotherapy technologies, a large number of patients undergo X-ray imaging every day in hospital radiology departments. Without proper protection, the X-rays generated during these procedures can cause unnecessary radiation exposure to non-examination areas of the patient and also affect surrounding medical staff. Existing radiology protective screens mostly use lead-containing radiation-proof fabric for hanging or rolling. Hanging lead-containing radiation-proof fabric requires frequent manual adjustment by operators, leading to cumbersome operations and reduced efficiency. Rolled lead-containing radiation-proof fabric generally has poor radiation protection effects, and the rolling design reduces the fabric's lifespan. Therefore, a new type of radiation protection screen is proposed to solve these problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a radiation protection screen, which aims to improve the existing technology where most protective screens use lead-containing radiation-proof fabric for hanging or rolling. Hanging lead-containing radiation-proof fabric requires frequent manual adjustment by operators, resulting in cumbersome operation and reduced efficiency; while rolling lead-containing radiation-proof fabric generally has poor radiation protection effect, and the rolling setting reduces the service life of the fabric.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A radiation protection screen includes a screen body, a radiation shielding plate on the back of the screen body, screws fixedly installed on both sides of the bottom of the screen body, a screw sleeve installed at the bottom of the screw, connecting blocks fixedly installed on both sides of the bottom of the radiation shielding plate, rollers fixedly installed on both sides of the bottom of the connecting blocks, and a flipping component for flipping the radiation shielding plate on one side of the screen body.

A second bevel gear 76 is fixedly installed at the output end of the motor 75. Wheel 76 meshes with the first bevel gear 74. Through the mutual cooperation of the first bevel gear 74, motor 75, and second bevel gear 76, starting the motor 75 can drive the second bevel gear 76 to rotate. The rotation of the second bevel gear 76 drives the first bevel gear 74 to rotate. The rotation of the first bevel gear 74 drives the connecting rod 73 to rotate. The rotation of the connecting rod 73 drives the second limiting block 72 to rotate. The rotation of the second limiting block 72 can drive the radiation shielding plate 2 to rotate, thereby achieving the advantage of adjusting the angle of the radiation shielding plate 2. A protective cover 8 is fixedly installed on the top of the screen body 1. The motor 75 is located inside the protective cover 8. Heat dissipation grooves 9 are provided on the front and rear sides of the protective cover 8. Through the mutual cooperation of the protective cover 8 and the heat dissipation grooves 9, the motor 75 can be protected, preventing medical personnel from accidentally touching the motor 75 when adjusting the angle of the radiation shielding plate 2. Under the action of the heat dissipation grooves 9, the motor 75 can be effectively cooled, preventing the motor 75 from overheating and being damaged.

[0031] Reference Figure 1-4The front of the screen-splitter body 1 is provided with an observation window 10. The back of the observation window 10 contacts the front of the screen-splitter body 1. The four corners of the front of the observation window 10 are detachably installed to the screen-splitter body 1 by bolts.

A handle 11 is fixedly installed on the front of the screen-splitter body 1. The handle 11 is located at the bottom of the observation window 10. The handle 11 facilitates the opening and closing of the screen-splitter body 1. The movement of the shielding plate 2 and the screen splitter body 1 is improved. A round block 12 is fixedly installed at the bottom of the screw 3. The bottom of the round block 12 contacts the bottom of the inner wall of the screw sleeve 4. An anti-slip pad 13 is fixedly installed at the bottom of the screw sleeve 4. Through the cooperation of the round block 12 and the anti-slip pad 13, the round block 12 can limit the screw 3 and prevent the screw sleeve 4 from disengaging from the screw 3 when rotating. The anti-slip pad 13 can improve the anti-slip performance of the screw sleeve 4 and prevent the screen splitter body 1 from shaking under the action of the shielding plate 2.

[0032] Working principle: When it is necessary to adjust the angle of the radiation shield 2, the screw sleeve 4 can be rotated. The screw sleeve 4 moves to the bottom and contacts the ground. Then the motor 75 can be started. The output end of the motor 75 drives the second bevel gear 76 to rotate. The rotation of the second bevel gear 76 drives the first bevel gear 74 to rotate. The rotation of the first bevel gear 74 drives the connecting rod 73 to rotate. The rotation of the connecting rod 73 drives the second limit block 72 to rotate. The rotation of the second limit block 72 can drive the radiation shield 2 to rotate, thereby achieving the advantage of adjusting the angle of the radiation shield 2. This can protect medical personnel and users. When taking pictures of the user's body, the medical personnel can observe through the observation window 10 to know the user's condition.
