Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of glasses frame, especially relates to a glasses frame with adjustable glasses legs. BACKGROUND

[0002] The glasses frame is used for supporting the lens as the core component of glasses, and is usually composed of glasses legs and a frame. The glasses legs can rotate around the frame to achieve the purpose of storage and folding. In the prior art, the end of the glasses leg is designed as a bendable structure, so that the bending degree can be adjusted to provide different wearing experiences for the wearer.

[0003] At present, the end of the glasses leg is mainly bent by a rotating part capable of deflecting and a limiting part abutting against the rotating part. The rotating part and the limiting part are connected in a contact mode. The deflection angle is maintained by the friction between the rotating part and the limiting part during rotation. Even if the friction still exists during deflection, the friction between the rotating part and the limiting part gradually decreases and cannot maintain the deflection angle as the deflection adjustment is performed. The service life of the deflection function is short due to the structural design. UTILITY MODEL CONTENT

[0025] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0026] This utility model embodiment provides an adjustable eyeglass frame with adjustable temples, such as Figures 1-5 As shown, the adjustable temple eyeglass frame includes:

[0027] The frame 400 and the first temple and the second temple respectively disposed on both sides of the frame 400, the first temple and the second temple are symmetrical structures and are rotatably connected to both sides of the frame 400 respectively;

[0028] The first temple includes a temple main rod 100 and a temple deflector 200 rotatably connected to the temple main rod 100. By rotating the temple deflector 200, the angle relationship between the temple main rod 100 and the temple deflector 200 can be changed to obtain different fixing and clamping effects.

[0029] The end of the main stem 100 of the glasses leg is provided with a hinge ring 101, the main stem 100 of the glasses leg is rotatably connected with the ear seat provided on the frame 400 through the hinge ring 101, the end of the main stem 100 of the glasses leg away from the frame 400 is provided with a deflection groove 102, the deflection groove 102 is provided with a deflection rod 310, a locking rod 320 and a limiting piece 330; the deflection rod 310 is assembled on the main stem 100 of the glasses leg at the deflection groove 102 in a threaded manner;

[0030] The deflection rod 200 of the glasses leg includes an arc-shaped rod 210 and a deflection head 220 connected with the arc-shaped rod 210, the deflection head 220 extends into the deflection groove 102, the deflection head 220 is provided with a deflection shaft hole 221, the deflection head 220 is nested in the deflection rod 310 through the deflection shaft hole 221;

[0031] The locking rod 320 includes an expansion ring 323, a main rod body 321 and a limiting rubber ring 322, the main rod body 321 is inserted into the deflection groove 102 from the outside of the main stem 100 of the glasses leg, the main rod body 321 is provided with an outer end plate 326 at the outer side part of the main stem 100 of the glasses leg, the limiting rubber ring 322 is arranged at the side of the main rod body 321 away from the outer end plate 326, and the expansion ring 323 is located at the middle segment of the main rod body 321;

[0032] The limiting piece 330 includes a support seat 331 and a limiting ring 332, the limiting ring 332 is made of rubber, the limiting ring 332 is arranged at one end of the support seat 331, the support seat 331 is embedded in the groove of the side wall of the deflection groove 102, the support seat 331 provides a reference positioning function to avoid the limiting ring 332 made of flexible material from being easily deviated, and the locking rod 320 penetrates the limiting ring 332 and uses the expansion ring 323 to expand the limiting ring 332;

[0033] When the expansion ring 323 moves into the limiting ring 332, the limiting ring 332 is expanded outwardly due to the support of the expansion ring 323 and abuts against the outer edge of the deflection head 220; the expansion ring 323 adopts a variable diameter structure, the maximum outer diameter of the expansion ring 323 is greater than the inner diameter of the limiting ring 332, and the insertion of the expansion ring 323 allows the inner diameter and the outer diameter of the limiting ring 332 to increase synchronously;

[0034] In this embodiment, the movement of the expansion ring 323 changes the state of the rubber limiting ring 332, enabling it to flexibly limit and unlock the deflection head 220. When the deflection head 220 needs to be unlocked and rotated, the expansion ring 323 leaves the area where the limiting ring 332 is located. When locking is required, the expansion ring 323 is inserted into the limiting ring 332. The above method realizes the change of the locking state between the deflection head 220 and the limiting ring 332, avoiding the situation where the locking force between the rotating part and the limiting part decreases during long-term deflection due to a single state, which leads to the failure of the deflection function and extends the service life of the deflection structure.

[0035] Specific method: By pulling the end plate 326, the main rod 321 is moved outward as a whole, so that the expansion ring 323 on the main rod 321 leaves the area where the limiting ring 332 is located, thereby allowing the limiting ring 332 to reset from the deformed expansion state and disengage from the deflection head 220. After the rotation adjustment is completed, the end plate 326 is pressed again to push the main rod 321 back into the deflection groove 102.

[0036] In a preferred embodiment of this invention, the deflection groove 102 has a limiting groove 103 on its side wall, and the inner wall of the limiting groove 103 is also provided with an annular groove adapted to the limiting rubber ring 322. When the end of the main rod 321 is inserted into the limiting groove 103, the limiting rubber ring 322 is engaged in the annular groove. The main rod 321 is also provided with a retaining groove 324, and a retaining ring 325 is provided on the retaining groove 324 to limit the axial movement stroke of the main rod 321.

[0037] In this embodiment, the limiting rubber ring 322 and the annular groove are used to keep the expansion ring 323 inside the limiting ring 332 during the process of maintaining the holding effect. The slot 324 and the retaining ring 325 are used to prevent the main rod 321 from being inserted or pulled out excessively, causing the end of the main rod 321 to completely detach from the limiting groove 103.

[0038] In a preferred embodiment of this invention, the outer edge of the deflection head 220 away from the arc-shaped rod 210 is also provided with a deflection ratchet 222, and the deflection head 220 is connected to the limiting ring 332 through the deflection ratchet 222.

[0039] In this embodiment, the deflecting ratchet 222 is in contact with the flexible limiting ring 332, and the friction between them prevents the temple deflection rod 200 from easily deflecting.

However, those skilled in the art should understand that the present invention is not limited to the described order of actions, as some steps may be performed in other orders or simultaneously according to the present invention.
