Description

Technical Field

[0001] The utility model belongs to the technical field of spectacle structures, and particularly relates to an assembled elastic spectacle hinge and a pair of spectacles. Background Art

[0002] A spectacle hinge is used to connect the spectacle legs and the spectacle frame; generally, the spectacle legs in the spectacle frames used by people are strip-shaped, and the spectacle legs and the spectacle frame are connected through a hinge structure. When the spectacles are in use, the spectacle legs are fully opened, placed on the ears, and clamped on both sides of the face to fix the spectacle frame. Usually, the opening amplitude of the spectacle legs cannot just adapt to the head width of the wearer. If the opening amplitude of the spectacle legs is too small, it will clamp the head and cause discomfort in wearing. If the opening amplitude of the spectacle legs is too large, it will cause insufficient stability in wearing the spectacles and the problem that the spectacle frame is prone to shift.

[0003] There is a type of existing elastic spectacle hinge, which has a certain elasticity between the spectacle legs and the spectacle frame by setting an elastic structure, so as to improve the adaptability and wearing comfort. However, this kind of elastic spectacle hinge usually has a large volume, and there are problems of difficult assembly and poor structural stability of the assembled body.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] In order to make the technical problems, technical solutions and beneficial effects solved by the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0022] See Figure 1 and Figure 2As shown in the figure, an embodiment of the present utility model provides an assembled elastic spectacle hinge, which includes a first connecting portion 1, a second connecting portion 2 and an elastic member 3. One end of the first connecting portion 1 is provided with a first hinge portion 11, and one end of the second connecting portion 2 is provided with a second hinge portion 21. The elastic member 3 includes an arc portion 31 and a third hinge portion 32. The arc portion 31 is an annular-like structure with an opening. The arc portion 31 has a first end 311 and a second end 312 that can approach or move away from each other at the opening position. The first end 311 is connected to the third hinge portion 32. The first hinge portion 11, the second hinge portion 21 and the third hinge portion 32 are coaxially hinged to form a hinge structure. The elastic member 3 is disposed around the first hinge portion 11 and the third hinge portion 32. When the spectacle leg is unfolded to approximately 90°, the first connecting portion 1 directly or indirectly abuts against the first end 311, and the second connecting portion 2 directly or indirectly abuts against the second end 312. When the spectacle leg is further expanded from approximately 90°, the distance between the first end 311 and the second end 312 gradually decreases, and the elastic member 3 undergoes elastic deformation to provide elasticity for restricting further outward expansion of the spectacle leg.

[0023] In the assembled elastic spectacle hinge, the first connecting portion 1, the second connecting portion 2 and the elastic member 3 are respectively provided with a first hinge portion 11, a second hinge portion 21 and a third hinge portion 32. By assembling the first hinge portion 11, the second hinge portion 21 and the third hinge portion 32, a hinge structure can be formed. The assembly is convenient, and this assembly structure is beneficial to strengthening the connection strength between components, ensuring the stability of the overall structure and improving the service life. In the assembled elastic spectacle hinge, the design of using the arc portion 31 to surround the first hinge portion 11 and the third hinge portion 32 is adopted. The internal space of the arc portion 31 is filled by the first hinge portion 11 and the third hinge portion 32, realizing the full utilization of space, reducing the volume of the elastic hinge for spectacles, and avoiding problems of aesthetics or wearing comfort caused by the too large volume of the elastic hinge for spectacles.

[0024] In this embodiment, the first hinge portion 11, the second hinge portion 21 and the third hinge portion 32 are all annular-like structures. The number of the second hinge portions 21 is 2, and the 2 second hinge portions 21 are arranged in parallel at intervals. The first hinge portion 11 and the third hinge portion 32 are coaxially stacked and accommodated between the 2 second hinge portions 21. A hinge screw is provided to pass through the first hinge portion 11, the second hinge portion 21 and the third hinge portion 32 to form a hinge structure.

[0025] The hinge screw is fixed on the 2 second hinge portions 21, and the first hinge portion 11 and the third hinge portion 32 rotate relative to the hinge screw.

[0026] The second hinge part 21 is provided with two, and the first hinge part 11 and the third hinge part 32 are arranged between the two second hinge parts 21. The two second hinge parts 21 play a role in structural protection for the first hinge part 11 and the third hinge part 32 therein. The annular part surrounds the outer periphery of the first hinge part 11 and the third hinge part 32, thereby forming a relatively sealed assembled elastic spectacle hinge structure, which can effectively avoid the interference between the assembled elastic spectacle hinge and environmental factors during the unfolding or retracting of the spectacle legs.

[0027] By laminating the first hinge part 11, the second hinge part 21 and the third hinge part 32, while ensuring their mutual rotation, the contact area of the three is increased, which is beneficial to ensuring the stability and strength of the overall structure.

[0028] In this embodiment, the number of the first hinge parts 11 is two. The two first hinge parts 11 are arranged in parallel at intervals, and an annular groove 12 is formed between the two first hinge parts 11. The third hinge part 32 is inserted into the annular groove 12.

[0029] During the assembly process, the two first hinge parts 11 can be inserted into the arc part 31 from the opening position of the arc part 31, and the third hinge part 32 is inserted into the annular groove 12 between the two first hinge parts 11, so as to achieve self-positioning, effectively reducing the positioning difficulty during assembly and being convenient to operate.

[0030] In this embodiment, the inner diameter of the arc part 31 is larger than the outer diameter of the first hinge part 11, so that a deformation space is left between the arc part 31 and the first hinge part 11, which is beneficial to ensuring the elastic effect of the elastic member 3.

[0031] In this embodiment, the opening width of the arc part 31 is greater than or equal to the outer diameter of the first hinge part 11, so as to facilitate the insertion of the first hinge part 11 from the opening of the arc part 31.

[0032] In this embodiment, a first clamping block 313 is provided at the first end 311 of the arc part 31, and a second clamping block 314 is provided at the second end 312 of the arc part 31. When the spectacle leg is unfolded to approximately 90°, the first clamping block 313 abuts against the first connecting part 1, and the second clamping block 314 abuts against the second connecting part 2.

[0033] When the temple is further expanded outward from approximately 90°, the second hinge portion 21 drives the second end portion 312 of the arc portion 31, and the first connecting portion 1 drives the first end portion 311 of the arc portion 31, so that the first end portion 311 and the second end portion 312 of the arc portion 31 are relatively close to each other, playing a role in providing the elasticity for the outward expansion of the temple.

[0034] In this embodiment, an arc-shaped groove is provided on the inner wall of the second hinge portion 21, and the second clamping block 314 is slidably disposed in the arc-shaped groove.

[0035] During the process of the temple being unfolded or retracted, the second hinge portion 21 and the elastic member 3 rotate relative to each other. At this time, the second clamping block 314 slides in the arc-shaped groove to adapt to the rotation of the second hinge portion 21. When the temple is unfolded to approximately 90°, the second clamping block 314 abuts against the end of the arc-shaped groove, that is, the second clamping block 314 abuts against the second connecting portion 2 to provide an elastic force for restricting the further rotation of the second hinge portion 21.

[0036] In this embodiment, the elastic member 3 is an integrally formed metal member or non-metal member, and the metal member is selected from one of zirconium-based amorphous alloys, copper-based amorphous alloys, iron-based amorphous alloys, magnesium-based amorphous alloys, and titanium-based amorphous alloys.

[0037] In a preferred embodiment, the elastic member 3 is selected from zirconium-based amorphous alloys.

[0038] The zirconium-based amorphous alloy has high material strength, and its tensile strength is 800 - 1500 MPa, which is 2.5 times that of 316 stainless steel and 1.5 times that of titanium alloy. The hinge structure can be designed to be thinner and lighter, reducing the weight of the accessories and improving the comfort of the wearer. At the same time, due to the high material strength, it ensures that the glasses do not deform during long-term use, improving the quality of the glasses. And the Vickers hardness of the zirconium-based amorphous alloy is 440 - 540 Hv, far exceeding that of stainless steel and titanium alloy, with little wear during use. It does not deform and the elasticity does not decrease during long-term use. The elastic deformation rate of the zirconium-based amorphous alloy material is 0.6 - 1.5%, which is 6 times higher than that of 316 stainless steel, with better elasticity and better wearing comfort.

[0039] In this embodiment, the assembled elastic glasses hinge further includes a gasket. In different embodiments, the number of gaskets is single or multiple. The gasket is disposed between the surfaces with relative rotation between the first hinge portion 11, the second hinge portion 21, and the third hinge portion 32, and the hinge screw passes through the gasket.

[0040] In this embodiment, the gasket is located between the first hinge portion 11 and the second hinge portion 21. The gasket is made of red copper and has a self-lubricating function, which can reduce the friction between structures, thereby improving the wear resistance of the hinge structure and extending the service life of the hinge structure.

[0041] In this embodiment, the number of the gaskets is two.

[0042] In this embodiment, the assembled elastic spectacle hinge further includes a damping member (not shown), and the damping member is used to provide damping during the relative rotation of the first connecting portion 1 and the second connecting portion 2.

[0043] The friction force generated by the damping member forms damping to enable the spectacle legs to hover at any point during the unfolding and retracting processes and maintain the stability of the spectacle legs at the hovering position. In particular, when the spectacle legs are in the unfolded and retracted states, even if the spectacle frame is taken alone at this time, the spectacle legs will not shake.

[0044] In this embodiment, the damping member is arranged on the second connecting portion 2, and the damping member abuts against the outer wall of the arc portion 31.

[0045] The method of abutting the damping member against the outer wall of the arc portion 31 to achieve damping has a long service life, good stability and a wide installation allowable error. Because the arc portion 31 itself has elasticity, by abutting the damping member against the arc portion 31, the pressure between the arc portion 31 and the damping member can be made to be in a relatively moderate state by relying on the elasticity of the arc portion 31, avoiding problems such as serious wear caused by too high pressure or too small damping caused by too low pressure. At the same time, after the damping member is worn to a certain extent, a certain damping effect can also be maintained by relying on the adaptive deformation of the arc portion 31. Its damping retention effect after wear is better, and it also has a higher dimensional tolerance rate during installation.

[0046] In this embodiment, the damping member is a plastic part.

[0047] Compared with other materials, by using a plastic part as the damping member, it has the characteristic of stable damping. Specifically, plastics with wear-resistant characteristics can be selected, such as polyoxymethylene, nylon, polycarbonate, polyurethane, polytetrafluoroethylene, polyamide, polysulfone, polyether ether ketone, polybutylene terephthalate, polyphenylene sulfide, etc. Fillers or fibers can also be added to the plastic part to play a reinforcing role.

[0048] Another embodiment of the present utility model provides a pair of glasses, which comprises an assembled elastic glasses hinge, a glasses frame and glasses legs as described above. A socket is provided on the glasses frame, one of the first connecting portion 1 and the second connecting portion 2 is connected to the socket, and the other one of the first connecting portion 1 and the second connecting portion 2 is connected to the glasses legs.

[0049] It should be noted that in the description of the present utility model, unless otherwise specified, the term "connection" may be a split connection or an integrally formed one. Specifically, the connection between the first connecting portion 1 and the second connecting portion 2 and the socket and the glasses legs may be the connection of independent structures or an integrally formed structure.

[0050] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
