Description

TECHNICAL FIELD

[0001] The utility model relates to a length-adjustable glasses leg structure. BACKGROUND

[0002] In the use process of glasses, the adaptability of glasses leg length has always been a key problem. The glasses leg of traditional glasses is usually fixed length, which cannot be flexibly adjusted according to the head size of the user and the wearing habit. This makes many users feel uncomfortable when wearing glasses. If the glasses leg is too short, it will tightly squeeze the two sides of the head, causing strong tightness. Long-term wearing is easy to cause discomfort. If the glasses leg is too long, the glasses are easy to slip off, not only affecting normal vision, but also possibly falling suddenly and damaging in sports or daily activities, causing many inconveniences to the user.

[0003] Moreover, some so-called "adjustable" glasses legs in the prior art have complex structure and cumbersome adjustment operation, and need to be assisted by special tools, so that the user is difficult to adjust to the appropriate length conveniently. In addition, when the glasses need to be repaired, cleaned or replaced with accessories, the glasses leg and the glasses frame are often difficult to disassemble, which brings great inconvenience to after-sales maintenance and increases the time and labor cost.

[0016] The structure of the length-adjustable temple structure of the utility model embodiment is shown in the figure Figures 1-5The hinge 1 is provided with a clamping joint at one end, used for connecting with the frame, and the other end of the hinge 1 is connected with the front end of the temple 2. The temple 2 is connected with the frame through the clamping joint of the hinge 1. The other end of the hinge 1 is provided with a plug-in part 11, and the front end of the temple 2 is provided with a plug-in hole 21. The plug-in part 11 and the plug-in hole 21 constitute a movable plug-in connection. A plurality of positioning grooves 22 are uniformly arranged on the inner wall of one side of the plug-in hole 21 along the plug-in direction. A first notch 12 is arranged on the corresponding side of the plug-in part 11. A first elastic arm 13 is arranged in the first notch 12. The front end of the first elastic arm 13 is connected with the front end of the first notch 12, and the rear end of the first elastic arm 13 extends towards the rear end of the first notch 12. The rear end of the first elastic arm 13 is provided with a first clamping block 14 which is used for clamping and positioning with the positioning groove 22. A first gap is arranged between the first elastic arm 13 and the first notch 12, which allows the first elastic arm 13 to swing towards the inside of the first notch 12. The first elastic arm 13 can give a certain elasticity to the first clamping block 14, so that the first clamping block 14 is elastically pressed on the inner wall of one side of the plug-in hole 21 and can move along the inner wall of the plug-in hole 21. When the first clamping block 14 moves into the positioning groove 22, it can be clamped and positioned with the positioning groove 22, so as to keep the temple 2 at a corresponding length. When a larger force is applied, the first elastic arm 13 swings towards the inside of the first notch 12 by using the force between the first clamping block 14 and the positioning groove 22 (both have arc contact surfaces), so that the first clamping block 14 can be separated from the positioning groove 22, thereby achieving clamping and positioning with different positioning grooves 22, and realizing length adjustment of the temple 2 in multiple gears.

[0017] The other side inner wall of the insertion hole 21 is uniformly provided with a anti-drop groove 23 penetrating through the insertion hole 21 from the inside to the outside along the insertion direction, the other side of the insertion part 11 is provided with a second notch 15, the second notch 15 is provided with a second elastic arm 16, the rear end of the second elastic arm 16 is connected with the rear end of the second notch 15, the front end of the second elastic arm 16 extends towards the front end of the second notch 15, the front end of the second elastic arm 16 is provided with a second clamping block 17 which is matched and clamped with the anti-drop groove 23, the second elastic arm 16 and the second notch 15 are provided with a second gap which allows the second elastic arm 16 to swing towards the inside of the second notch 15, the front end of the second elastic arm 16 is obliquely arranged away from the second notch 15. The second elastic arm 16 can provide a certain elasticity to the second clamping block 17, so that the second clamping block 17 is elastically pressed on the other side inner wall of the insertion hole 21 and can move along it, the elastic force provided by the second elastic arm 16 can first improve the contact effect between the insertion part 11 and the one side inner wall of the insertion hole 21, improve the reliability of the connection between the insertion part 11 and the temple 2, on the other hand, the second clamping block 17 can be clamped with the anti-drop groove 23, which can prevent the temple 2 from falling out, so that the temple 2 part is not easy to lose. The anti-drop groove 23 has a flat side wall, because the front end of the second elastic arm 16 is inclined outward, when pulling out the insertion part 11 in the outward direction, the second clamping block 17 is resisted by the side wall of the anti-drop groove 23, even if a larger force is applied, it is also difficult to pull out, at this time, the positioning of the two can be released by pushing the second clamping block 17 inward from the outside of the anti-drop groove 23, so that the insertion part 11 can be completely pulled out of the insertion hole 21, which is convenient for disassembly and assembly.

[0018] The inside of the temple 2 is provided with a window at a position corresponding to the plurality of positioning grooves 22, the window includes a plurality of first windows 241 corresponding to the positions of the positioning grooves 22, and a second window 242 (strip-shaped) located below and connected with the plurality of first windows 241, the window is convenient for the processing and forming of the positioning grooves 22 in the insertion hole 21, and can also facilitate the intuitive viewing of the extension length of the temple 2.

[0019] The hinge 1 includes a limiting block 18 located at the front end of the insertion part 11, the limiting block 18 is limitedly matched with the front end of the temple 2, for limiting the maximum depth of the insertion part 11 inserted into the insertion hole 21, which is convenient for the insertion and installation of the temple 2 and the insertion part 11.

[0020] In addition, it also includes a decorative cover 3 fixedly matched with the hinge 1, the upper and lower sides of the front end of the insertion part 11 are provided with limiting blocks 18, the upper and lower sides of the decorative cover 3 are respectively welded and fixed with the two limiting blocks 18, the outside of the front end of the temple 2 is provided with a U-shaped notch 25, the decorative cover 3 is embedded in the U-shaped notch 25, the setting of the decorative cover 3 can play a decorative role and improve the aesthetic appearance of the temple 2.

[0021] The above embodiment is only one of preferred specific embodiments of the present application, and common changes and replacements made by those skilled in the art within the technical scheme of the present application are included in the protection scope of the present application.
