Detailed ways

The present utility model will be described in detail below with reference to the accompanying drawings and embodiments.

Referring to FIG. 1 , FIG. 2 , and FIG. 3 , an embodiment of the headband adjustment structure 2 of the head-mounted protective device 1 of the present invention is suitable for being detachably installed on the head-mounted protective device 1 . The head-mounted protective device 1 includes a main body 11 surrounding a head-mounted space 111 . The headband adjustment structure 2 includes four binding pieces 21 detachably disposed at the inner edge of the main body 11 and located in the head-wearing space 111 , connecting the binding pieces 21 and located in the head-wearing space 111 . A main ring piece 22, a female buckle 23 connected to one end of the main ring piece 22, a male buckle connected to the other end of the main ring piece 22 and passing through the female buckle 23 24 , and an auxiliary force-applying member 25 integrally formed and protruding on the male buckle strap 24 . The coupling member 21 is detachably clamped to the slot 112 formed at the inner edge of the main body 11 through a tenon structure, and the main body 11 can form more than four slots 112 to allow the coupling member 21 It can be inserted into a suitable slot 112 according to requirements. The main ring piece 22 is formed with four sliding grooves (not shown in the figure) for the coupling elements 21 to be provided respectively. Each sliding groove extends along the circumferential direction of the main ring piece 22 , so that the corresponding connecting piece 21 can slide along the sliding groove to adjust the position of the connecting piece 21 on the main ring piece 22 .

Referring to FIGS. 2 , 3 , and 4 , the female buckle 23 includes a first body portion 231 connected to one end of the main ring piece 22 , connected to the first body portion 231 and defining a through slot A seat portion 233 of the 232, and an adjusting button portion 234 which is provided on the seat portion 233 and can be pressed. The male buckle 24 includes a second body portion 241 connected to the other end of the main ring piece 22 , and is continuously protruded from the second body along the extending direction of the second body portion 241 . A plurality of positioning teeth 242 on the part 241 . The male buckle 24 , the female buckle 23 , and the main ring piece 22 cooperate to form a sleeve head ring 26 . The female buckle 23 can be pressed to switch between the adjustment state and the positioning state as shown in FIG. 4 . When the adjustment buckle portion 234 is not pressed, the end of the adjustment buckle portion 234 opposite to the pressed position will be moved. It extends downward into the through-groove 232, and is clamped between any two adjacent positioning teeth 242, so that the male buckle 24 is fixed and cannot be penetrated relative to the female buckle 23. When the female buckle 23 is in the positioning state, the size (referring to the circumference) of the sleeve head ring 26 is fixed. When the adjustment buckle portion 234 is pressed, the adjustment buckle portion 234 is deflected or deformed as a whole, so the end locked between the positioning teeth 242 as described above will move upward, so that it is no longer locked to the The teeth 242 are positioned so that the male buckle 24 can be stretched relative to the female buckle 23 to adjust the size of the sleeve head ring 26. At this time, the female buckle 23 is adjusted as described above. state. The auxiliary force-applying member 25 is protruded from the second belt body portion 241 , and has two concave arc surfaces 251 opposite to each other and concave inwards, one of the concave arc surfaces 251 faces the male buckle 24 . In the extending direction, the other concave arc surface 251 faces the main ring piece 22 .

After wearing the head-mounted protective device 1 , the user can press the adjustment buckle portion 234 with one hand to make the female buckle 23 switch to the adjustment state, and push against the auxiliary force applying member 25 with the other hand. Facing the concave arc surface 251 of the main ring piece 22 , the part of the second belt body 241 passing through the through-slot 232 is increased to reduce the sleeve head ring 26 , thereby enabling the head-mounted protective device 1 The inside can fit the user's head and be firmly worn. Conversely, if the user's head is larger than the head ring 26, the user can push against the other concave arc surface 251 of the auxiliary force applying member 25, so that the second belt body 241 is Pulled outward, and the set head ring 26 is enlarged through the reduction of the part of the through-groove 232, so that the user can find a size suitable for their own head. After adjusting to a suitable size, the user can release the adjustment buckle portion 234, and let the adjustment buckle portion 234 be clamped between the corresponding two adjacent positioning teeth 242, so that the female buckle 23 is switched to the positioning state to fix the size of the sleeve head ring 26 . The shape of the concave arc surface 251 allows the user to comfortably place their fingers on it and apply force, and the wrapping arc surface makes the user easy to apply force and is not easy to slip off, so as to achieve the effect of improving the operating feel. .

Referring to FIG. 5 , the head-mounted protective device 1 applied in this embodiment can also be a safety face shield. In this state, the headband adjustment structure 2 only includes two coupling parts 21 , and the coupling parts 21 is directly pivotably fixed at the inner edge of the main body 11 . In this state, the auxiliary force-applying member 25 can also achieve the effect of facilitating the user's operation and preventing the fingers from slipping off. Therefore, this embodiment can be applied to a variety of different head-mounted protective devices 1, and thus has a relatively high performance. High versatility.

To sum up, in the present invention, through the concave arc surface 251 of the auxiliary force applying member 25, the user is easy to apply force and is not easy to slip off when operating the auxiliary force applying member 25, so the utility model can indeed be achieved. Purpose.
