Description of the invention: - [Technical field to which the invention pertains] The present invention relates to a goggles and a diving lens belt length adjustment structure, which mainly means that the headband can be adjusted with ease, and the binding stability is Wear comfort and assembly integrity. [Prior Art] Conventional goggles and goggles generally have a buckle for adjusting the length of the headgear, and the buckle is generally disposed on the side of the goggles, the main body of the goggles or the position behind the head, such as The figure shown in FIG. 9 is one of the conventional structures, mainly for the rigid buckle 1, one end is provided with a joint portion n for hooking with the goggle body 2', and the other portion is provided with a knot portion 12'. Further, the bundle portion 12 is provided with two cross bars 121, 122 at the center, so that the headband 3 can be folded in two times around the cross bars 121, 122. However, in the foregoing structure, when the headband 3 is to be adjusted, the tightening of the headband 3 and a crosspiece 121', 122' must be relaxed in order to adjust the inconvenience, and the #环1' is recorded. 2, for the design of the separable design, the integrity of the Yang suit is not ^ ^ missing, and the 11% external force of the joint is still easy to cause with the goggle body 2, 'fall off the 虞; when worn, the hard buckle 1 It is attached to the two sides of the human head and has a lack of wearing comfort. Further, as shown in the tenth figure, the inventor previously designed Announcement No. 571792, the US-made m-mirror buckle structure, the Qiaosaki body 4, the pressing portion 41, the beam-binding portion 42, and the pressing portion 41 The bundled portion 42 has a bendable connecting portion 43 and is coupled. ^91884 The pressing portion 41 is further provided with a column body 411, and a pressing portion 412 for holding the * hand is disposed outside the pressing portion 41, and the binding portion, 42 is provided at one end for the insertion pair The headband has a 5' bundle hole 421', and the bundled hole 411 has a snap edge 422 for the card head 5'. When assembled, the buckle body 41 can be bent and disposed on the main body 6' of the goggles by the connecting portion 43, and the pressing portion 41 is located on the outer side of the swimming body 6 and the headband 5 is inserted at one end. The hole 421 ', and then surrounds the cylinder 411, and then the bundled hole 421 is worn through the protruding group. The foregoing structure, when adjusted, can stretch the folding head band 5, the outer side 51, and the end portion so as to be stretchable to the length and tightness of the corresponding user demand. Referring to the eleventh figure, when the opening tape 5 is placed, the pair of folding tapes 5, the inner side 52, the pulling force is the stretchable pressing portion 41, the cylinder 411, and the cylinder 4 ι, and the clamping The edge 422 can be tightly fastened to the headband 5, and the headband 5 can be fixed, and the length of the strap can be adjusted. Please refer to the twelfth figure. When the headband 5 is to be relaxed, the tilting portion 41 can be moved. The cylinder 4H' can be unfolded with the engaging edge 422, and the folded headband 5, the inner '52' can be stretched to relax the headband 5. The Kawasaki structure has a clear 5, which is a synergistic effect of the longitudinal fit. However, the buckle body 4 and the goggle body 6 are separate components, so that the combined integrity is not good, and the buckle body is worn when worn. 4, the bundle portion 42, the inner side will be placed against the side of the head, resulting in a lack of wearing comfort. Also, as shown in the thirteenth to fifteenth drawings, the U.S. special _272, and the goggles 6 1291884 have a lens 71', a ring frame 72, two separate buckles 73, 74, and a headband 75, Composition, and the two buckles 73', the lens 71, the ring frame 72, the outer side, and the buckle 73, the crossbar 731' is provided, and the buckle is corresponding to the buckle to displace" so that the buckle 74 When the inner side of the buckle 73' is displaced, the pressing portion 741 can be pressed against the headband 75, and the end portion 742' can be hooked to the headband 75, and the flange 751 is fixed; and the buckle (four) and the buckle 73' When the outer side is displaced, the pressing portion 741' can not be pressed against the headband 75, and the length of the headband 75' can be adjusted. The structure of the foregoing structure is slidably displaced to the fixed head W5' by the buckle 74, but if the head strap 75' is too strong, the buckle 74 is still caused, the sliding and the headband 75, _ the positioning of the prison is not good, and The two fasteners 73, 74 are separated components and then joined to the mirrors 471 and 76, so that the component shirts are missing, and the two fasteners 73', 74 may still be collided with the lens after the combination. Ring frame 72 is detached. In addition, as shown in the sixteenth figure, the new structure No. 263132 includes two separate buckles 81, 82' combined with the goggle body 83', and a buckle 82, a crossbar 821, and a crosshead V84 The rod 821' is assembled, and the clip 81 is disposed, and the elastic piece 8U is disposed, and the positioning block 812 is disposed, so that the positioning block 812 can be pressed against the head band 84 by the elastic force of the elastic piece 811, and can be pressed and positioned. Block 812 causes the positioning block 812 to be disengaged from the headband 84' to adjust the headgear length. In the foregoing structure, when the elastic piece 811 is elastic and fatigued, the headband 84 is still caused, the positioning of the cow is not good, and the structural components are numerous, and the assembly is inconvenient, and the buckles 81', 82 and the goggle body 83 are provided. , in a separate design, causing the buckle 81, ❿ 1291884 to collide with the goggle body 83' when it collides. New type M27 () 836, M272554, M269934, • No. 5, No. M2_, Announcement No. 35 goggles buckle only by the 5U strength of the buckle itself The _ _ belt positioning, and thus the tension of the headband is greater than the clamping force, which will lead to the fascination. SUMMARY OF THE INVENTION The object of the present invention is to provide a headband binding positioning stability design, and to combine assembly integrity, wearing comfort, assembly convenience, component simplification and better economic efficiency. efficacy. In addition, the present invention includes the goggles, the goggle body, the buckle, and the headband combination for the foregoing purposes, and the goggles and the goggle main system are disposed on the two sides _ the joint for engaging the buckle, and the joint The part has a through hole for piercing the folding headband, and a pressing edge is arranged outside the through hole, and the abutting surface is arranged on the other side; and the fastening device can cover the front and the hole, and the cover is The side is provided with a non-slip surface, and a side plate which can be accommodated in the through hole is protruded on two sides of the inner surface of the cover plate, and an abutting surface is arranged corresponding to the abutting surface position, and a perforation is arranged between the side plates, and the pivoting is provided at the pivoting a rod, and the crossbar and the cover plate _ can be worn to extend the headband _, and the buckle is assembled with the goggles and the main body of the snorkel, and the crossbar and the pressing edge are provided with a gap between the head and the head, and The abutting surface of the buckle and the swimming goggles and the main body of the goggles can be displaced by the mask; the headband is made of a soft material, and two protrusions are arranged at the front end, and the two convex portions are spaced apart and protruded laterally.
