Description

Technical Field

[0001] The present invention relates to the technical field of lead glasses, in particular to an anti-slip device and lead glasses. Background Art

[0002] Lead glasses are a special type of protective eyewear, primarily designed to block or reduce eye damage from ionizing radiation such as X-rays and gamma rays. The lenses of lead glasses contain lead or other high-density materials. Lead has a high atomic number and density. When radiation (such as X-rays and gamma rays) strikes the lenses, the lead atoms interact with the radiation, absorbing or scattering the radiation's energy through processes such as the photoelectric effect, Compton scattering, and the electron pair effect. This reduces the intensity of the radiation that reaches the eyes through the lenses, effectively protecting the eyes from radiation damage.

[0003] In hospital radiology departments, medical staff are exposed to a certain amount of X-ray radiation when performing X-ray fluoroscopy, photography, CT scans, and other examinations on patients. Lead glasses can effectively block some X-rays, reducing the radiation dose to sensitive areas such as the lens, and lowering the risk of eye diseases (such as cataracts) caused by long-term or frequent X-ray exposure.

[0004] During medical examinations, the lead glasses worn by medical staff have the following problems. The lenses of lead glasses contain lead or other high-density materials and are heavy. Wearing them for a long time will put pressure on the bridge of the nose and ears, causing the lead glasses to slide down. The continuous pressure will make the wearer feel uncomfortable or even painful, affecting the smooth progress of the examination process. In addition, frequent activities or facial sweating of medical staff will cause the lead glasses to slide down.

[0005] Therefore, how to design an anti-slip device that can prevent lead glasses from sliding down and avoid them causing pressure on the bridge of the nose and ears is a technical problem that has not yet been solved in the prior art. Summary of the Invention

On the other side, under the drive of a rotational external force, it can rotate relative to the first adjusting member 2, thereby driving the first adjusting wheel 21 to rotate. The rotation of the first adjusting wheel 21 drives the second adjusting wheel 22 to rotate, so that the two adjusting ropes 3 are extended outward or retracted inward at the same time; a first locking structure is provided on the first adjusting member 2 and the first adjusting cap 4; in the initial state, the first adjusting cap 4 is rotationally locked, thereby keeping the adjusting rope 3 locked; when subjected to a pressing external force, the rotation lock of the first adjusting cap 4 is released, thereby releasing the lock on the adjusting rope 3, so that the first adjusting cap 4 can rotate under the drive of the rotational external force.

[0039] When medical personnel examine patients wearing lead glasses, they first install the two adjustment cords 3 on the temples on both sides of the lead glasses and roughly adjust the length of the adjustment cords 3. After the adjustment is completed, they first put on the lead glasses, then put the main body 1 on the head, and then rotate the first adjustment cap 4 counterclockwise. The two adjustment cords 3 will be retracted inward at the same time, pulling the lead glasses with a certain force, so that the lead glasses fit the medical personnel's face to prevent them from sliding down. When the lead glasses need to be removed from the face, they press the first adjustment cap 4 and rotate it clockwise. The two adjustment cords 3 are released outward at the same time, loosening the pull on the lead glasses, so that the lead glasses can be removed from the face. The anti-slip device of this embodiment can flexibly adjust the length of the adjustment cords according to individual circumstances and can be locked at any time. While ensuring the stability of the lead glasses, it also takes into account the wearing comfort, reducing the protective burden of medical personnel during medical examinations.

The second adjusting cap 6 rotates through the second inner gear ring 71 to drive the second outer gear 54 to rotate, and drives the third adjusting wheel 51 to rotate. The rotation of the third adjusting wheel 51 drives the fourth adjusting wheel 52 to rotate, so that the two adjustment ropes 3 extend outward at the same time, and the lead glasses are lowered. Then press the first adjusting cap 4 and rotate it clockwise, the first adjusting cap 4 moves toward the direction close to the first adjusting member 2 and squeezes the first elastic member 46, and the first annular ratchet 41 and the first ratchet gear 42 are separated; the first adjusting cap 4 rotates through the first inner ring gear 7 to drive the first outer gear 24 to rotate, and drives the first adjusting wheel 21 to rotate, and the first adjusting wheel 21 rotates to drive the second adjusting wheel 22 to rotate, so that the two adjusting ropes 3 extend outward at the same time, loosening the pull on the lead glasses, so that the lead glasses can be removed from the face.
