Referring to FIG. 1 to FIG. 7 , the present invention provides a screwless assembly structure for glasses. The eyeglassless assembly structure 10 mainly includes a frame 1 and two mirror legs 2 .

As shown in FIG. 1 to FIG. 5 , the frame 1 has two connecting ends 11 , and each connecting end 11 extends with a shaft 12 . The end of each shaft 12 has a protrusion 13 and a first engaging portion 14 . Each of the first engaging portions 14 includes one or a plurality of latches 141 extending from the end of each of the shafts 12 and one side of each of the bumps 13.

The outer side wall 121 of the shaft 12 defines a notch groove 15 , and each of the latches 141 extends outward from the bottom wall 151 and the inner side wall 152 of each notch groove 15 . Each of the bumps 13 is a half-spherical block, and the outer diameter of each of the bumps 13 is larger than the outer diameter of the shaft 12, and each of the latches 141 is a semi-cylindrical block.

As shown in FIG. 1 to FIG. 5, each of the temples 2 is provided with a pivot hole 21, and the inner wall 211 of each pivot hole 21 has a second engaging portion 22, and each shaft 12 is pivotally connected to each pivot. Each of the first and second engaging portions 14 and the second engaging portions 22 can be engaged with each other in a plurality of stages.

Further, each of the second engaging portions 22 includes a plurality of card slots 221 opened from the inner wall 211 of each of the pivot holes 21, and each of the latches 141 can be engaged by one of the plurality of card slots 221.

In addition, a hook block 212 protrudes from one side of the inner wall 211 of each of the pivot holes 21, and each of the hook blocks 212 gradually decreases in thickness toward the respective protrusions 13. The card slots 221 are respectively from the inner side walls 213 of the hook blocks 212. The forming is performed inward, and each of the hooks 141 and the hooks 212 are engaged with each other, and each of the bottom walls 151 and the hooks 212 are stopped from each other.

Each of the card slots 221 of the embodiment is a recessed groove extending through the inner side wall 213 of each of the hook blocks 212 and the top wall 23 and the outer side wall 24 of each of the temples 2, but is not limited thereto.

In addition, the latch 141 of the first engaging portion 14 and the latching slot 221 of the second engaging portion 22 of the embodiment can also be reversely disposed, that is, each first engaging portion 14 includes the end of the shaft 12 and Each of the second latching portions 22 includes one or more latches extending from the inner wall 211 of the pivoting hole 21, and each latch can be selected from a plurality of latching slots. One of them is stuck.

As shown in FIG. 2 to FIG. 5, the combination of the screwless assembly structure 10 of the present invention utilizes two connecting ends 11 at both ends of the frame 1, each of which extends a shaft 12, and the end of each shaft 12 There is a bump 13 and a first engaging portion 14; one end of each of the temples 2 is provided with a pivot hole 21, and the inner wall 211 of each pivot hole 21 has a second engaging portion 22, and each shaft 12 is pivotally connected to the shaft Each of the pivot holes 21 and the temples 2 are restrained between the respective connecting ends 11 and the respective bumps 13 , and the first engaging portions 14 and the second engaging portions 22 can be engaged with each other in multiple stages. Therefore, the frame 1 and the temple 2 of the present invention are connected by a pivotal connection and a multi-segment engagement manner, thereby omitting the conventional screw-locking manner, so as to achieve the advantages of structural stability and convenient assembly of the screwless assembly structure 10. .

As shown in FIG. 6 to FIG. 7 , it is a schematic diagram of the use state of the screwless assembly structure 10 of the present invention.
