Description

Technical Field

[0001] The utility model relates to the technical field of glasses and glasses accessories, in particular to a screw-free hidden elastic glasses leg and a glasses frame. Background Art

[0002] In the field of glasses, the frame usually refers to the frame part that directly wraps and fixes the lens, and the glasses frame is the skeleton of the entire glasses. The glasses frame is usually composed of a frame, a stud and a temple. At present, the temples of glasses are mostly hinged and fastened to the stud by metal screws. For example, a new type of rotating positioning device structure for the temples of glasses disclosed in the Chinese utility model with publication number CN217543566U also inevitably uses screws to connect the stud and the temple arm. However, this method of connecting with screws can easily cause the screws to slip during the assembly process, thereby causing product defects; at the same time, during use, this method is also easy to loosen or even fall off, and users need to frequently check the tightness of the screws. If they fall off, they need to go to the glasses store for repair, which is very inconvenient; and the screws of the glasses are small, and the method of connecting with screws requires the use of a special small screwdriver whether in assembly or disassembly, which is also inconvenient to disassemble.

The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments, and are not intended to limit the present invention.

[0071] like Figure 1 to Figure 9 As shown, in an embodiment of the utility model, a screwless hidden elastic eyeglass leg is provided, comprising: an eyeglass leg 1, a stud 2 and a U-shaped connecting buckle 3. Among them:

[0072] The temple 1 has a first elastic bifurcated leg 11 and a second elastic bifurcated leg 12 at one end, the first elastic bifurcated leg 11 having a first abutting surface 1121;

[0073] The pile head 2 has a second abutment surface 212 at one end thereof that matches the first abutment surface 1121;

[0074] 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, and an insertion port 35 is formed between the bottom of the U-shaped connecting buckle 3 and the hinged portion 34, into which the first elastic forked leg 11 and the second elastic forked leg 12 are inserted. Specifically, the hinged portion 34 is a connecting shaft or a hinged protrusion.

[0075] It should be mentioned that the screw connection between the stud 2 and the temple 1 in the prior art also has the following problems: the tightness of the screw needs to be considered separately. When the screw is too loose, the temple 1 and the screw are easy to fall off. When the screw is too tight, the temple 1 will be hindered from being retracted and extended, and may even be insufficiently retracted and not fully extended.

[0076] In this solution, a hinged portion 34 hinged to the pile head 2 is provided on the U-shaped connecting buckle 3, so that the U-shaped connecting buckle 3 and the pile head 2 are movably connected, and an insertion port 35 is formed between the inner bottom of the U-shaped connecting buckle 3 and the hinged portion 34. The first elastic forked leg 11 and the second elastic forked leg 12 of the temple 1 are slightly pressed and inserted into the insertion port 35 of the U-shaped connecting buckle 3. After insertion, they have a certain elastic preload force, and the first abutting surface 1121 of the first elastic forked leg 11 abuts against the second abutting surface 212 of the pile head 2, and the second elastic forked leg 12 abuts against the inner bottom of the U-shaped connecting buckle 3. Furthermore, the temple 1 can be unfolded and folded. When unfolded, the first abutting surface 1121 of the first elastic bifurcated leg 11 abuts against the second abutting surface 212 of the stump 2; when folded, the temple 1 and the stump 2 rotate relative to each other, so that the first abutting surface 1121 and the second abutting surface 212 are at an angle, until the first abutting surface 1121 and the second abutting surface 212 are perpendicular, and the temple 1 is folded. The first elastic bifurcated leg 11 and the second elastic bifurcated leg 12 are squeezed and inserted into the plug interface 35 of the U-shaped connecting buckle 3 to provide a certain elastic preload, so that the temple 1 has a certain internal and external elastic force during the unfolding and folding process, making the unfolding and folding process more convenient, efficient and sufficient, avoiding the obstruction problem caused by the over-tightening of the traditional screw connection, and avoiding the problem of the temple 1 being loose due to the over-loosening of the traditional screw, which affects the wearing discomfort. Moreover, the structure is compact and does not leak, and the concealing effect is good. The fastening degree of the accessory connection is high, and the accessory will not fall off due to the loosening of the screw. It is easy to disassemble and assemble, and no special tools are required. There is no problem of screw stripping, and it is durable, which not only improves the product assembly efficiency, but also reduces the defective rate.

[0077] In one embodiment, Figure 7 and Figure 8As shown, the bottom of the plug-in port 35 is provided with a locking protrusion 311, and the second elastic bifurcated leg 12 is provided with a locking notch 123 matching the locking protrusion 311. Specifically, the first elastic bifurcated leg 11 and the second elastic bifurcated leg 12 are inserted into the plug-in port 35 until the locking notch 123 of the second elastic bifurcated leg 12 is locked with the locking protrusion 311 on the U-shaped connecting buckle 3. Thus, the firmness of the connection is further improved to prevent the temple 1 from being separated from the U-shaped connecting buckle 3.

[0078] In another embodiment, Figure 8 As shown, a first plug-in portion 111 is provided at the end of the first elastic bifurcated leg 11, a first avoidance notch 112 is recessed on one side of the first plug-in portion 111 away from the second elastic bifurcated leg 12, and the first abutting surface 1121 is located at the bottom wall of the first avoidance notch 112;

[0079] The end of the second elastic bifurcated leg 12 is provided with a second plug-in portion 121, and a side of the second plug-in portion 121 close to the first plug-in portion 111 is provided with a second avoidance notch 122 buried by the first plug-in portion 111, and the bayonet 123 is provided on a side of the second plug-in portion 121 away from the second avoidance notch 122;

[0080] The pile head 2 is provided with a first connecting section 21 hinged to the hinge portion 34, and a third avoidance notch 22 for accommodating the first plug-in portion 111 and the second plug-in portion 121 is formed at one end of the pile head 2 close to the first connecting section 21, and the second abutting surface 212 is located at a side of the first connecting section 21 close to the third avoidance notch 22, and the first avoidance notch 112 matches the first connecting section 21. Specifically, the occupied space is better. Thus, the compactness and hiding effect of the structure are further improved.

[0081] In yet another embodiment, Figure 6~Figure 8 As shown, the first connecting 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 avoiding notch 112 is provided 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.

[0082] In yet another embodiment, Figure 3 , Figure 6 and Figure 8As shown, the U-shaped connecting buckle 3 includes a connecting edge 31 and connecting ears 32 respectively arranged on both sides of the connecting edge 31, the connecting ears 32 are provided with a first axial hole 321, a pre-folding 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 along the pre-folding line 33 to form a predetermined angle. Specifically, a pre-folding 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-folding line 33 so that the connecting edge 31 and the connecting ears 32 are perpendicular.

[0083] In another embodiment, if Figure 3 , Figure 6 and Figure 8 As shown, the locking protrusion 311 is provided on a side of the connecting edge 31 close to the first shaft hole 321 or the locking protrusion 311 is the connecting edge 31. Specifically, the locking protrusion 311 that is locked by the locking opening 123 of the second elastic bifurcated leg 12 may be provided on the connecting edge 31; or the connecting edge 31 may be thickened to form the locking protrusion 311 that can be locked by the locking opening 123.

[0084] In another embodiment, if Figure 4~Figure 8 As shown, the pile head 2 is an arched structure, and the length of the third abutting surface 213 is less than the length of the first abutting surface 1121. Specifically, Figure 8 and Fig. 9 As 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 is automatically folded under the action of the internal elastic force, making the folding of the temple 1 more convenient and complete, and avoiding jamming.

[0085] In another embodiment, a spectacle frame includes any one of the aforementioned screwless hidden elastic spectacle legs, and further includes:

[0086] The frame is connected to the end of the stump 2 away from the temple 1 .

[0087] In another embodiment, if Fig.16 ~ Fig. 20 As shown, the spectacle frame also includes:

[0088] The bracket 4 has a buckle 41 and a plug 42 at one end, and the other end is connected to the frame, the buckle 41 includes two claw fingers 411, and the plug 42 is arranged between the two claw fingers 411; and

[0089] The stipule 5 has a support block 51 fastened by two claw fingers 411 on one side wall, and the support block 51 has a column insertion hole 511 inserted by the insertion column 42. Thus, the applicability and use experience are further improved, and the wearing comfort is higher.

[0090] Another embodiment, such as Fig.18 As shown, a block position 412 into which the support block 51 is inserted is formed between the two claw fingers 411 , and the insertion column 42 extends from the bottom of the block position 412 . A fatigue-resistant seam 421 is provided at the bottom of the insertion column 42 .

[0091] Installation process: Figure 6 As shown, align the second axial hole 211 on the pile head 2 with the first axial hole 321 on the U-shaped connecting buckle 3, and then connect the first axial hole 321 and the second axial hole 211 through the hinge part 34 to complete the installation of the pile head 2 and the U-shaped connecting buckle 3. Figure 7 and Figure 8 As shown, after the pile head 2 and the U-shaped connecting buckle 3 are installed, the first elastic forked leg 11 and the second elastic forked leg 12 on the temple 1 are pressed against each other for a certain distance, so that the first plug-in portion 111 and the second plug-in portion 121 can be close to each other and generate a certain elastic force, the first plug-in portion 111 and the second plug-in portion 121 are inserted into the plug interface 35 and are located in the third avoidance gap 22 until the bayonet 123 is clamped on the clamping protrusion 311 or the connecting edge 31. At this time, the first connecting section 21 is placed in the first avoidance gap 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.

[0092] The stump 2 and the U-shaped connecting buckle 3 are linked and combined into a whole by a hinge 34 (i.e., a connecting shaft) through the second shaft hole 211 and the first shaft hole 321; the temple 1 is inserted into the U-shaped gap (i.e., the plug-in port 35) of the U-shaped connecting buckle 3, the second plug-in portion 121 of the second elastic bifurcated leg 12 hooks the clamping protrusion 311 or the connecting edge 31 of the U-shaped connecting buckle 3 through the bayonet 123, and the first plug-in portion 111 of the first elastic bifurcated leg 11 is held against the stump 2, and the temple 1 generates an outward push force due to the space difference between the first plug-in portion 111 and the second plug-in portion 121 to form an elastic force. The structural design of this solution is ingenious and concise, and saves production costs. While changing the traditional temple 1 that needs to be welded and screwed, it can also enable the temple 1 to have a certain internal and external elastic force, making the glasses more comfortable to wear.

[0093] Temple 1 retraction and extension process: Fig. 9As shown, when the temple 1 is unfolded, the stud 2 (specifically the first connecting section 21) and the temple 1 are at 180°, and the first abutting surface 1121 abuts against the second abutting surface 212. When the temple 1 is folded, the stud 2 (specifically the first connecting section 21) and the temple 1 are at 90°, and the first abutting surface 1121 abuts against the third abutting surface 213. In addition, under the action of internal and external elastic forces, the stud 2 (specifically the first connecting section 21) and the temple 1 can also be at a greater than 180° situation, such as 197° in the figure, thereby improving the toughness and fault tolerance when unfolded and effectively avoiding breakage.

[0094] like Figure 10~Figure 15 As shown, in the embodiment of the utility model, a U-shaped hook elastic buckle type temple structure is provided, comprising: a temple 1, a gasket 14 and a weight 15. Among them:

[0095] The temple 1 has a U-shaped hook 13 at one end, and an elastic buckle 131 is provided at the end of the U-shaped hook 13;

[0096] A gasket 14 abuts against the side wall of the U-shaped hook 13;

[0097] The weight 15 is provided with a receiving cavity 151 into which the temple 1 and the gasket 14 are inserted, and the inner wall of the receiving cavity 151 is provided with a buckle hole 152 matching the elastic buckle 131. Specifically, the weight 15 can also be used as a decorative piece.

[0098] In this solution, a U-shaped hook 13 is provided at one end of the temple 1 away from the pile head 2, and an elastic buckle 131 is provided on the U-shaped hook 13, and then a gasket 14 is provided and inserted into 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 a receiving cavity 151 is provided on the counterweight 15 to accommodate the assembly of the U-shaped hook 13 and the gasket 14, and a buckle hole 152 is provided in the receiving cavity 151, so that the assembly of the U-shaped hook 13 and the gasket 14 can be fastened to the buckle hole 152 through the elastic buckle 131 after being inserted into the receiving cavity 151, thereby completing the clamping and fixing. The gasket 14 can effectively improve the preload 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 is achieved between the counterweight 15 and the U-shaped hook 13 of the temple 1, so that the temple cover can be inserted from one end of the U-shaped hook 13 of the temple 1 first, and then the counterweight 15 is connected, which ensures easy installation of the temple cover while improving the tightness of the connection between the temple 1 and the counterweight 15 and the convenience of installation, and effectively avoids the loosening and falling off of eyeglass accessories such as the counterweight 15.

[0099] In one embodiment, Fig.12 and Fig.13As shown, the gasket 14 is a U-shaped gasket 14 inserted into the U-shaped hook 13. Specifically, the gasket 14 is inserted into the U-shaped hook 13 and then inserted into the accommodating cavity 151 of the counterweight 15 until the elastic buckle 131 is inserted into the buckle hole 152 to form a tight fit connection.

[0100] In another embodiment, Fig.12 As shown, one end of the U-shaped hook 13 is connected to the temple 1 , and the elastic buckle 131 is disposed on the other end of the U-shaped hook 13 .

[0101] In yet another embodiment, Fig.12 and Fig.13 As shown, the U-shaped hook 13 has a waist-shaped hole structure in the middle, and the gasket 14 includes two pads 141 and a connecting part 142 connected to the two pads 141. The pad 141 is provided with a weight-reducing waist-shaped hole 1411 that matches the waist-shaped hole structure.
