Description

[Technical Field]

[0001] This application belongs to the field of eyeglass connection technology, specifically relating to a connection mechanism between eyeglass head and temple. [Background Technology]

[0002] In modern life, eyeglasses, as a tool to assist vision, have expanded their function beyond simply correcting vision problems to include eye protection and decorative purposes. Eyeglasses can correct various vision impairments, including myopia, hyperopia, astigmatism, presbyopia, strabismus, and amblyopia. However, in traditional eyeglass designs, the connection between the lenses and the frames relies on screws. This structure requires tools to adjust the frames, increasing the complexity of the operation. Furthermore, exposed screws not only affect the aesthetics of the eyeglasses but can also lead to problems such as difficulty in opening and closing and rusting. [Summary of the Invention]

[0003] To address the cumbersome installation and removal procedures for lenses and frames in existing technologies, this application provides a connection mechanism for eyeglass posts and temples.

[0004] This application is achieved through the following technical solution:

[0005] A connection mechanism for eyeglasses head and temple includes a connecting protrusion located at one end of the temple and extending outward, a connecting notch formed on the eyeglasses head for the connecting protrusion to engage, a positioning protrusion passing through the connecting protrusion and protruding outward from the upper and lower surfaces of the connecting protrusion, and a positioning through hole formed on the inner wall of the eyeglasses head for the positioning protrusion to engage to keep the eyeglasses head and temple connected.

[0006] As described above, in a connection mechanism between an eyeglass stand and a temple, the inner wall of the eyeglass stand is provided with a mounting groove extending from the positioning through hole toward the temple.

[0007] As described above, in a connection mechanism for eyeglasses head and temple, the top surface of the mounting groove gradually slopes upward from the positioning through hole toward the temple, and the bottom surface of the mounting groove gradually slopes downward from the positioning through hole toward the temple.

[0008] In the above-described connection mechanism between the eyeglass head and temple, the height of the positioning protrusion is H, the maximum height of the mounting groove is B, and the height H of the positioning protrusion is adapted to the maximum height B of the mounting groove.

[0009] As described above, in a connection mechanism for eyeglass head and temple, the positioning protrusion is in the shape of an arc polygon with a minimum diameter of D, and the width of the mounting groove is L. The minimum diameter D of the positioning protrusion is adapted to the width L of the mounting groove.

[0010] As described above, in a connection mechanism for eyeglass head and temple, the positioning through hole is circular with a diameter of R, and the maximum diameter of the positioning protrusion is S. The maximum diameter S of the positioning protrusion is greater than the width L of the mounting groove and is compatible with the diameter R of the positioning through hole.

[0011] In the eyeglass stand and temple connection mechanism described above, when the positioning protrusion slides along the mounting groove, the eyeglass stand and temple are interference-fitted.

[0012] As described above, in a connection mechanism between an eyeglass stand and a temple, the positioning through hole partially passes through the eyeglass stand upwards and extends downwards through the eyeglass stand.

[0013] In the eyeglass head and temple connection mechanism described above, the positioning through hole is elliptical in shape.

[0014] In the eyeglass stand and temple connection mechanism described above, when the temple is folded relative to the eyeglass stand, the minimum diameter D of the positioning protrusion faces the mounting groove; when the temple is unfolded relative to the eyeglass stand, the maximum diameter S of the positioning protrusion faces the mounting groove.

[0015] Compared with the prior art, this application has the following advantages:

[0016] This application discloses a connection mechanism between the eyeglass stand and the temple. An outwardly extending connecting protrusion is provided at one end of the temple, which engages with a connecting notch on the eyeglass stand to form a mounting position. Simultaneously, the connecting protrusion has positioning protrusions that pass through and protrude outwards from its upper and lower surfaces. The inner wall of the eyeglass stand has a positioning through-hole for the positioning protrusions to engage. When the positioning protrusions engage with the positioning through-hole using an interference fit, the temple and the eyeglass stand are immediately connected. This simplifies the installation and removal process, eliminates the need for tools, improves the user experience, and, because there are no exposed screws, makes the overall appearance of the eyeglasses more concise and aesthetically pleasing. It also avoids the problem of difficulty in opening and closing caused by rusted screws in traditional designs, thereby extending the lifespan of the eyeglasses. [Attached Image Description]

Detailed Implementation Methods

[0026] To make the technical problems solved by this application, the technical solutions, and the beneficial effects clearer, this application 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 merely illustrative of this application and are not intended to limit this application.

[0027] Please see Figures 1 to 8 A connection mechanism for eyeglasses head and temple includes a connecting protrusion 2 located at one end of the temple 1 and extending outward, a connecting notch 4 formed on the eyeglasses head 3 and fitted with the connecting protrusion 2, a positioning protrusion 5 passing through the connecting protrusion 2 and protruding outward from the upper and lower surfaces of the connecting protrusion 2, and a positioning through hole 6 formed on the inner wall of the eyeglasses head 3 and into which the positioning protrusion 5 is inserted to keep the eyeglasses head 3 connected to the temple 1.

[0028] This application discloses a connection mechanism between the eyeglass stand and the temple. An outwardly extending connecting protrusion is provided at one end of the temple, which engages with a connecting notch on the eyeglass stand to form a mounting position. Simultaneously, the connecting protrusion has positioning protrusions that pass through and protrude outwards from its upper and lower surfaces. The inner wall of the eyeglass stand has a positioning through-hole for the positioning protrusions to engage. When the positioning protrusions engage with the positioning through-hole using an interference fit, the temple and the eyeglass stand are immediately connected. This simplifies the installation and removal process, eliminates the need for tools, improves the user experience, and, because there are no exposed screws, makes the overall appearance of the eyeglasses more concise and aesthetically pleasing. It also avoids the problem of difficulty in opening and closing caused by rusted screws in traditional designs, thereby extending the lifespan of the eyeglasses.

[0029] Furthermore, as a preferred embodiment of this solution and not a limitation, the inner wall of the eyeglass post 3 is provided with a mounting groove 7 extending from the positioning through hole 6 toward the temple 1.

[0030] In this embodiment, by providing a mounting groove 7 extending from the self-positioning through hole 6 towards the temple 1, a channel is provided for the positioning protrusion 5 to slide into the positioning through hole, so that the temple can be easily installed and removed from the eyeglass holder.

[0031] Furthermore, as a preferred embodiment of this solution and not a limitation, the top surface of the mounting slot 7 gradually slopes upward from the positioning through hole 6 toward the temple 1, and the bottom surface of the mounting slot 7 gradually slopes downward from the positioning through hole 6 toward the temple 1.

[0032] In this embodiment, the inclined top and bottom surfaces provide a guiding function for the positioning protrusion 5, so that the positioning protrusion can squeeze the upper and lower surfaces of the inner wall of the eyeglass post head outward during the sliding installation process, thereby achieving an interference fit. After installation, that is, after the positioning protrusion is inserted into the positioning through hole, the temple is not easy to fall out of the installation slot at any folding angle relative to the eyeglass post head, thus improving the user experience.

[0033] Furthermore, as a preferred embodiment of this solution and not a limitation, the height of the positioning protrusion 5 is H, the maximum height of the mounting slot 7 is B, and the height H of the positioning protrusion 5 is adapted to the maximum height B of the mounting slot 7.

[0034] In this embodiment, when the height H of the positioning protrusion 5 matches the maximum height B of the mounting slot 7, the positioning protrusion 5 can be smoothly initially aligned with the mounting slot 7, enabling a quick alignment operation. Subsequently, by applying external force to press, the positioning protrusion slides along the mounting slot and is inserted into the positioning through hole 6 through an interference fit.

[0035] Furthermore, as a preferred embodiment of this solution and not a limitation, the positioning protrusion 5 is in the shape of an arc polygon with a minimum diameter of D, the width of the mounting groove 7 is L, and the minimum diameter D of the positioning protrusion 5 is adapted to the width L of the mounting groove 7.

[0036] In this embodiment, the arc-shaped polygonal positioning protrusion 5 ensures structural strength while precisely matching its minimum diameter D with the width L of the mounting slot 7, so that the positioning protrusion can be inserted into the mounting slot at a specific angle. This fit avoids the problem of the positioning protrusion 5 getting stuck in the mounting slot 7 due to being too tight or shaking due to being too loose, thus ensuring a flexible and stable connection between the temple 1 and the eyeglass stand 3.

[0037] Furthermore, as a preferred embodiment of this solution and not a limitation, the positioning through hole 6 is circular in shape and has a diameter of R, the maximum diameter of the positioning protrusion 5 is S, and the maximum diameter S of the positioning protrusion 5 is greater than the width L of the mounting groove 7 and is adapted to the diameter R of the positioning through hole 6.

[0038] In this embodiment, the circular positioning through hole 6 matches the maximum diameter S of the positioning protrusion 5, ensuring that the positioning protrusion 5 will not become loose after being inserted into the positioning through hole 6, thereby achieving a reliable connection between the temple 1 and the eyeglass stand 3. Furthermore, it avoids the positioning protrusion 5 becoming stuck due to excessive tightness within the positioning through hole 6, improving the overall durability of the eyeglasses.

[0039] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, when the positioning protrusion 5 slides along the mounting groove 7, the eyeglass post 3 and the temple 1 are interference-fitted.

[0040] In this embodiment, the interference fit ensures that the positioning protrusion 5 will not loosen or misalign due to the gap in the mounting slot 7 during sliding, thereby maintaining the stability of the connection between the temple 1 and the eyeglass post 3. This tight fit effectively prevents the temple 1 from accidentally sliding or falling off during use, improving the reliability and durability of the eyeglasses.

[0041] Furthermore, as a preferred embodiment of this solution and not a limitation, the positioning through hole 6 partially extends upward through the eyeglasses post head 3 and extends downward through the eyeglasses post head 3.

[0042] In this embodiment, the design of the positioning through hole 6 partially passing through the eyeglass post head 3 upwards and downwards ensures a reliable connection between the positioning protrusion and the positioning through hole, while preventing drilling on the upper surface of the eyeglass post head, making the overall appearance of the eyeglasses more concise, beautiful and elegant.

[0043] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, the positioning through hole 6 is elliptical in shape.

[0044] In this second embodiment, as Figure 8 As shown, the elliptical positioning through-hole 6, compared to the traditional circular hole, reduces the contact area between the positioning protrusion and the positioning through-hole. This results in less friction when the temple rotates relative to the eyeglass post, i.e., when the positioning protrusion 5 rotates within the positioning through-hole, reducing the likelihood of jamming. Simultaneously, the elliptical design allows the positioning protrusion to engage with the positioning through-hole 6 at a specific angle, i.e., at its minimum diameter.

[0045] Furthermore, as a preferred embodiment of this solution and not a limitation, when the temple 1 is folded relative to the eyeglass stand 3, the minimum diameter D of the positioning protrusion 5 faces the mounting groove 7; when the temple 1 is unfolded relative to the eyeglass stand 3, the maximum diameter S of the positioning protrusion 5 faces the mounting groove 7.

[0046] In this embodiment, since the glasses are in the unfolded state for a longer period of time than in the folded state, they are more susceptible to external forces. Therefore, the minimum diameter D of the positioning protrusion 5 is matched with the mounting slot 7, so that the temples 1 need to be in a relative folded angle to be installed and removed. After installation, they are less likely to fall off due to external forces during use.

[0047] The working principle of this embodiment is as follows:

[0048] This application discloses a connection mechanism between the eyeglass stand and the temple. An outwardly extending connecting protrusion is provided at one end of the temple, which engages with a connecting notch on the eyeglass stand to form a mounting position. Simultaneously, the connecting protrusion has positioning protrusions that pass through and protrude outwards from its upper and lower surfaces. The inner wall of the eyeglass stand has a positioning through-hole for the positioning protrusions to engage. When the positioning protrusions engage with the positioning through-hole using an interference fit, the temple and the eyeglass stand are immediately connected. This simplifies the installation and removal process, eliminates the need for tools, improves the user experience, and, because there are no exposed screws, makes the overall appearance of the eyeglasses more concise and aesthetically pleasing. It also avoids the problem of difficulty in opening and closing caused by rusted screws in traditional designs, thereby extending the lifespan of the eyeglasses.
