For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations. The terms used in the description of the present invention in this article are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0075] As Figures 1 to 9 shown, in the embodiments of the present utility model, a screwless hidden elastic temple is provided, including: a temple 1, a hinge 2, and a U-shaped connecting buckle 3. Among them:

[0076] One end of the temple 1 is provided with a first elastic bifurcated leg 11 and a second elastic bifurcated leg 12 that form an angle with each other, and the first elastic bifurcated leg 11 is provided with a first abutting surface 1121;

[0077] One end of the hinge 2 is provided with a second abutting surface 212 that matches the first abutting surface 1121;

[0078] The U-shaped connecting buckle 3 is provided with a hinged portion 34 hinged to one end of the pile head 2 close to the second abutting surface 212. An insertion opening 35 into which the first elastic bifurcated leg 11 and the second elastic bifurcated leg 12 are inserted is formed between the bottom of the U-shaped connecting buckle 3 and the hinged portion 34. Specifically, the hinged portion 34 is a connecting shaft or a hinged bump.

[0079] It should be noted that the following problems still exist in the screw connection between the pile head 2 and the temple 1 in the prior art: It is also necessary to pay attention to the tightness of the screw. When the screw is too loose, both the temple 1 and the screw are likely to fall off. When the screw is too tight, the unfolding and folding of the temple 1 will be blocked, and even the unfolding and folding will be insufficient and not in place.

[0080] In this solution, by providing a hinged portion 34 on the U-shaped connecting buckle 3 that is hinged to the pile head 2, the U-shaped connecting buckle 3 and the pile head 2 are movably connected. An insertion opening 35 is formed between the inner bottom of the U-shaped connecting buckle 3 and the hinged portion 34. The first elastic bifurcated leg 11 and the second elastic bifurcated leg 12 of the temple 1 are slightly pressed and inserted into the insertion opening 35 of the U-shaped connecting buckle 3. After insertion, it has a certain elastic pre-tightening force. The first abutting surface 1121 of the first elastic bifurcated leg 11 abuts against the second abutting surface 212 of the pile head 2, and the second elastic bifurcated leg 12 abuts against the inner bottom of the U-shaped connecting buckle 3. Furthermore, the unfolding and folding of the temple 1 are realized. When unfolding, the first abutting surface 1121 of the first elastic bifurcated leg 11 abuts against the second abutting surface 212 of the pile head 2; when folding, relative rotation occurs between the temple 1 and the pile head 2, so that the first abutting surface 1121 and the second abutting surface 212 form an angle until the first abutting surface 1121 and the second abutting surface 212 are perpendicular, completing the folding of the temple 1. By squeezing and inserting the first elastic bifurcated leg 11 and the second elastic bifurcated leg 12 into the insertion opening 35 of the U-shaped connecting buckle 3 to provide a certain elastic pre-tightening force, the unfolding and folding process of the temple 1 has certain inner and outer elastic forces, making the unfolding and folding process more convenient, efficient, and sufficient. It not only avoids the blocking problem caused by the traditional screw connection being too tight but also avoids the problem of the temple 1 being loose due to the traditional screw being too loose, which affects the uncomfortable wearing. Moreover, the structure is compact and does not protrude externally, with a good hidden effect. The fastening degree of the accessory connection is high, and there will be no situation where the accessories fall off due to the loosening of the screw. It is convenient to disassemble and assemble, and can be disassembled and assembled without additional special tools. There is no problem of screw thread slipping, and the durability is high. It not only improves the product assembly efficiency but also reduces the defective rate.

[0081] In one embodiment, as Figure 7 and Figure 8As shown, a clamping protrusion 311 is provided at the bottom of the insertion interface 35, and the second elastic bifurcated leg 12 is provided with a bayonet 123 that matches the clamping protrusion 311. Specifically, the first elastic bifurcated leg 11 and the second elastic bifurcated leg 12 are inserted into the insertion interface 35 until the bayonet 123 of the second elastic bifurcated leg 12 is clamped to the clamping protrusion 311 on the U-shaped connecting buckle 3. Furthermore, the firmness of the connection is further improved to prevent the temple 1 from detaching from the U-shaped connecting buckle 3.

[0082] In another embodiment, as Figure 8 shown, a first insertion portion 111 is provided at the end of the first elastic bifurcated leg 11. A first avoidance notch 112 is recessed on the side of the first insertion portion 111 away from the second elastic bifurcated leg 12, and the first abutting surface 1121 is located on the bottom wall of the first avoidance notch 112;

[0083] A second insertion portion 121 is provided at the end of the second elastic bifurcated leg 12. A second avoidance notch 122 into which the first insertion portion 111 is embedded is provided on the side of the second insertion portion 121 close to the first insertion portion 111, and the bayonet 123 is provided on the side of the second insertion portion 121 away from the second avoidance notch 122;

[0084] The stud 2 is provided with a first connection section 21 hinged to the hinge portion 34. A third avoidance notch 22 for accommodating the first insertion portion 111 and the second insertion portion 121 is formed at one end of the stud 2 close to the first connection section 21. The second abutting surface 212 is located on the side of the first connection section 21 close to the third avoidance notch 22, and the first avoidance notch 112 matches the first connection section 21. Specifically, the occupied space is better. Furthermore, the compactness and hiding effect of the structure are further improved.

[0085] In yet another embodiment, as Figures 6 to 8 shown, the first connection section 21 is further provided with a third abutting surface 213 adjacent to the second abutting surface 212, and the side wall of the first avoidance notch 112 is set as an inclined surface 1122. Specifically, the third abutting surface 213 is perpendicular to the second abutting surface 212. When the temple 1 is unfolded, the third abutting surface 213 is perpendicular to the first abutting surface 1121; when the temple 1 is folded, the third abutting surface 213 is in contact with the first abutting surface 1121.

[0086] In still another embodiment, as Figure 3 、 Figure 6 and Figure 8As shown, the U-shaped connecting buckle 3 includes a connecting edge 31 and connecting ears 32 respectively disposed on both sides of the connecting edge 31. The connecting ears 32 are provided with first shaft holes 321. A pre-fold line 33 is provided between the connecting edge 31 and the connecting ears 32. The connecting edge 31 and the connecting ears 32 are bent along the pre-fold line 33 to form a predetermined angle. Specifically, a pre-fold line 33 is provided between the connecting edge 31 and the connecting ears 32, and the connecting edge 31 and the connecting ears 32 are bent relative to each other along the pre-fold line 33 so that the connecting edge 31 and the connecting ears 32 are perpendicular to each other.

[0087] In another embodiment, as Figure 3 , Figure 6 and Figure 8 shown, the convex lug 311 is disposed on the surface of the connecting edge 31 close to the first shaft hole 321 or the convex lug 311 is the connecting edge 31. Specifically, a convex lug 311 held by the bayonet 123 of the second elastic bifurcated leg 12 can be additionally provided on the connecting edge 31; alternatively, the connecting edge 31 can be thickened to form a convex lug 311 that can be held by the bayonet 123.

[0088] In another embodiment, as Figures 4 to 8 shown, the stud 2 has an arcuate structure, and the length of the third abutting surface 213 is less than the length of the first abutting surface 1121. Specifically, as Figure 8 and Figure 9 shown, when the temple 1 is folded, the contact between the first abutting surface 1121 and the second abutting surface 212 can be smoothly switched to the contact between the first abutting surface 1121 and the third abutting surface 213. When the temple 1 is bent to a certain angle, it automatically folds under the action of internal elastic force, making the folding of the temple 1 more convenient and complete, and avoiding jamming.

[0089] In another embodiment, an eyeglass frame includes the screwless hidden elastic temple described in any one of the foregoing, and further includes:

[0090] A lens frame, connected to one end of the stud 2 away from the temple 1.

[0091] In another embodiment, as Figure 16 ~ Figure 20 shown, the eyeglass frame further includes:

[0092] A bracket 4, one end of which is provided with a claw 41 and a plug 42, and the other end is connected to the lens frame. The claw 41 includes two claw fingers 411, and the plug 42 is disposed between the two claw fingers 411; and

[0093] The stipule 5 has a support block 51 on one side wall, which is fastened by two of the claw fingers 411. The support block 51 has a column jack 511 into which the insertion post 42 is inserted. Furthermore, the applicability and user experience are further improved, and the wearing comfort is higher.

[0094] Another embodiment, as Figure 18 shown, a placement block position 412 into which the support block 51 is snapped is formed between the two claw fingers 411. The insertion post 42 extends from the bottom of the placement block position 412, and a fatigue-resistant seam 421 is provided at the bottom end of the insertion post 42.

[0095] Installation process: As Figure 6 shown, align the second shaft hole 211 on the pile head 2 with the first shaft hole 321 on the U-shaped connecting buckle 3, and then pass through the hinge portion 34 through the first shaft hole 321 and the second shaft hole 211 to complete the installation of the pile head 2 and the U-shaped connecting buckle 3. As Figure 7 and Figure 8 shown, after the pile head 2 and the U-shaped connecting buckle 3 are installed, press the first elastic bifurcated leg 11 and the second elastic bifurcated leg 12 on the temple 1 against each other by a certain distance, so that the first insertion portion 111 and the second insertion portion 121 can approach each other and generate a certain elastic force. The first insertion portion 111 and the second insertion portion 121 are inserted into the insertion opening 35 and are located in the third avoidance notch 22 until the bayonet 123 is clamped on the convex 311 or the connecting edge 31. At this time, the first connecting section 21 is placed in the first avoidance notch 112, the first abutting surface 1121 is in contact with the second abutting surface 212, and the third abutting surface 213 is perpendicular to the first abutting surface 1121.

[0096] The pile head 2 and the U-shaped connecting buckle 3 are linked by the hinge portion 34 (i.e., the connecting shaft) through the second shaft hole 211 and the first shaft hole 321 and combined into a whole; the temple 1 is inserted into the U-shaped gap (i.e., the insertion opening 35) of the U-shaped connecting buckle 3, and the second insertion portion 121 of the second elastic bifurcated leg 12 hooks the convex 311 or the connecting edge 31 of the U-shaped connecting buckle 3 through the bayonet 123. The first insertion portion 111 of the first elastic bifurcated leg 11 hidden inside abuts against the pile head 2, and the temple 1 forms an elastic force due to the outward top force generated by the interval space difference between the first insertion portion 111 and the second insertion portion 121. The structural design of this solution is ingenious and simple, saving production costs. While changing the traditional temple 1 that requires welding and screw connection, it can also make the temple 1 have a certain internal and external elastic force, making the glasses more comfortable to wear.

[0097] Temple 1 retraction and extension process: As Figure 9As shown, when the temple 1 is unfolded, the shank 2 (specifically, the first connecting section 21) and the temple 1 form an angle of 180°, and at this time, the first abutting surface 1121 abuts against the second abutting surface 212. When the temple 1 is folded, the shank 2 (specifically, the first connecting section 21) and the temple 1 form an angle of 90°, and at this time, the first abutting surface 1121 abuts against the third abutting surface 213. In addition, under the action of internal and external elastic forces, the shank 2 (specifically, the first connecting section 21) and the temple 1 can also form a situation where the angle is greater than 180°, such as 197° in the figure, thereby improving the toughness and fault tolerance during unfolding and effectively avoiding breakage.

[0098] As Figures 10 to 15 shown, in an embodiment of the present utility model, a U-shaped hook elastic snap-type temple structure is provided, including: a temple 1, a gasket 14, and a counterweight 15. Among them:

[0099] The temple 1 has a U-shaped hook 13 at one end, and an elastic snap 131 is provided at the end of the U-shaped hook 13;

[0100] The gasket 14 abuts against the side wall of the U-shaped hook 13;

[0101] The counterweight 15 is provided with a receiving cavity 151 into which the temple 1 and the gasket 14 are inserted, and a snap hole 152 matching the elastic snap 131 is provided on the inner side wall of the receiving cavity 151. Specifically, the counterweight 15 can also be used as a decorative part.

[0102] In this solution, by providing a U-shaped hook 13 at one end of the temple 1 away from the shank 2, and providing an elastic snap 131 on the U-shaped hook 13, then providing a gasket 14 and sleeving it on the U-shaped hook 13, so that the gasket 14 is in contact with the side wall of the U-shaped hook 13, and then providing a receiving cavity 151 in the counterweight 15 to accommodate the combination of the U-shaped hook 13 and the gasket 14, and providing a snap hole 152 in the receiving cavity 151, so that after the combination of the U-shaped hook 13 and the gasket 14 is inserted into the receiving cavity 151, it can be clamped in the snap hole 152 by the elastic snap 131 to complete the clamping and fixing. The gasket 14 can effectively improve the pre-tightening force and the firmness of the tight fit between the U-shaped hook 13 and the counterweight 15, and further prevent loosening. Furthermore, a convenient detachable connection between the counterweight 15 and the U-shaped hook 13 of the temple 1 is realized, so that the temple sleeve can be first sleeved from the end of the U-shaped hook 13 of the temple 1, and then the counterweight 15 is connected, which ensures the easy installation of the temple sleeve and at the same time improves the fastening degree of the connection between the temple 1 and the counterweight 15 and the convenience of installation, and also effectively avoids the situation where glasses accessories such as the counterweight 15 become loose and fall off.

[0103] In one embodiment, as Figure 12 and Figure 13As shown, the gasket 14 is a U-shaped gasket 14 that is sleeved into the U-shaped hook 13. Specifically, after the gasket 14 is sleeved into the U-shaped hook 13, it is inserted into the accommodation cavity 151 of the counterweight 15 until the elastic buckle 131 snaps into the buckle hole 152, forming a tight fit connection.

[0104] In another embodiment, as Figure 12 shown, one end of the U-shaped hook 13 is connected to the temple 1, and the elastic buckle 131 is provided at the other end of the U-shaped hook 13.

[0105] In still another embodiment, as Figure 12 and Figure 13 shown, the middle of the U-shaped hook 13 has a waist-shaped hole structure. The gasket 14 includes two pad portions 141 and a connecting portion 142 connecting the two pad portions 141. The pad portion 141 is provided with a weight-reducing waist-shaped hole 1411 that matches the waist-shaped hole structure. Specifically, the connecting portion 142 has an arc-shaped structure, enabling the elastic buckle 131 on the U-shaped hook 13 to be more adaptively snapped into the buckle hole 152, with high applicability, further improving the fastening degree of the connection and the convenience of installation.
