[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] The preferred embodiment of the present invention will be described below.

[0026] Please see Figure 1-5 As shown, the radiotherapy headband goggle protection device includes a goggle body 1 and a headband elastic component. The goggle body 1 includes a lens frame 101 and a light shield 102. The light shield 102 is connected to the inner side of the lens frame 101. The headband elastic component includes a first fixing strap 2, a first connecting strap 3 and an adjustable tension component 4. The first fixing strap 2 is fixedly installed on the side of the light shield 102. The other end of the first fixing strap 2 is engaged with the first connecting strap 3. The ends of the two first connecting straps 3 are connected to the adjustable tension component 4.

[0027] Furthermore, the main body of the goggles 1 is made of lead, a radiation protection material.

[0028] Furthermore, the light shield 102 includes a nose groove 1021, an arc-shaped groove 1022, and a cushioning pad 1023. The nose groove 1021 is located at the lower part of the light shield 102, and the arc-shaped groove 1022 is located on the inner side of the light shield 102. The inner top of the arc-shaped groove 1022 is also provided with a cushioning pad 1023. The nose groove 1021 and the arc-shaped groove 1022 allow the eye shield to better fit the patient's facial contours and reduce pressure. At the same time, the addition of the cushioning pad 1023 further improves the wearing comfort and reduces the discomfort that may be caused by prolonged wearing.

[0029] Specifically, the main body of the goggles 1 is made of lead, a radiation protection material, which can effectively absorb and block the radiation generated during radiotherapy. At the same time, the design of the light shield 102 fully considers ergonomics, so that the goggles can fit closely to the patient's facial contours and reduce radiation leakage. The design of the headband elastic part ensures that the patient can freely adjust the tightness of the goggles according to their own head circumference, which improves the comfort and stability of wearing. During radiotherapy, the patient only needs to wear the goggles correctly and adjust them to the appropriate tightness to effectively protect the eyes from radiation damage.

[0030] In another embodiment provided by this utility model, such as Figure 3-5 As shown, the side of the first connecting belt 3 is provided with a connecting buckle 301 that is fixedly engaged with the first fixing belt 2, and the other end face of the first connecting belt 3 is provided with a connecting groove 302, and a rod 303 is provided in the connecting groove 302.

[0031] Furthermore, the adjustable tension component 4 includes a second connecting strip 401 that engages with the first connecting strip 3. The side ends of the second connecting strips 401 on both sides are provided with engaging grooves 402 that cooperate with the insert rod 303. The other end face of the second connecting strip 401 is provided with a straight hole 403, and a toothed rack 404 is provided along the hole body inside the straight hole 403.

[0032] Furthermore, the adjustable tension assembly 4 also includes a knob cap 405, with a mounting ring 406 inside the knob cap 405, and a rotating shaft at the center of the inner end face of the knob cap 405. A gear 407 is sleeved on the outside of the rotating shaft, and a limiting cover 408 is provided on the end face of the gear 407. A rack 404 on the second connecting belt 401 cooperates with the gear 407.

[0033] Specifically, the first connecting band 3 is secured to the first fixing band 2 via the connecting buckle 301 on its side. Next, observe the connecting groove 302 on the other end of the first connecting band 3 to ensure the insert rod 303 is correctly installed in the groove 302. At this point, the insert rod 303 acts as a temporary fixing device to help maintain the position of the first connecting band 3. The second connecting band 401 in the adjustable tension assembly 4 is then secured to the first connecting band 3. The snap-fit ​​groove 402 on the side of the second connecting band 401 is aligned with the insert rod 303, and gently pressed down to fully embed the insert rod 303 into the snap-fit ​​groove 402, completing the initial securing. Then, hold the knob cap 405 and gently rotate it. The gear 407 inside the knob cap 405 will rotate accordingly. Since the gear 407 engages with the rack 404 on the second connecting band 401, the rotation of the gear 407 will cause the second connecting band 401 to move along the length of the straight hole 403. In this way, the relative position between the second connecting belt 401 and the first connecting belt 3 can be adjusted by rotating the knob cap 405, thereby achieving the purpose of adjusting the tightness.

[0034] In use, firstly, secure the first fixing strap 2 to the first connecting strap 3 via the connecting buckle 301 to ensure a firm connection and prevent it from falling off during use. Then, align the snap-fit ​​groove 402 on the side of the second connecting strap 401 with the insert rod 303 and press it down gently so that the insert rod 303 is fully embedded in the snap-fit ​​groove 402. Next, align the light shield 102 of the eye mask body 1 with the eyes, ensuring that the nose groove 1021 is located below the nose and the arc groove 1022 fits the facial contour. At this time, the cushioning pad 1023 will provide additional comfort. Then, adjust the tightness of the eye mask according to the user's fit by holding the knob cap 405 and rotating it gently. The gear 407 inside the knob cap 405 will rotate with the rotation. Since the gear 407 cooperates with the rack 404 on the second connecting strap 401, the rotation of the gear 407 will drive the second connecting strap 401 to move along the length direction of the straight hole 403. In this way, the relative position between the second connecting belt 401 and the first connecting belt 3 can be adjusted by rotating the knob cap 405, thereby achieving the purpose of adjusting the tightness. When the tightness is adjusted to a satisfactory position, stop rotating the knob cap 405. Due to the presence of the limit cover 408, the rack 404 will be limited on the gear 407, thereby ensuring that the tightness will not be unable to be adjusted due to the rack 404 slipping off.
