DETAILED DESCRIPTION

[0031] In order to make the technical problems and beneficial effects of the technical solutions solved by the present application more clear, the present application will be further described in detail below in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application, and are not used to limit the present application.

[0032] Please refer to Figures 1 to 8 , a connecting mechanism of a temple head and a temple leg, comprising a connecting protrusion 2 provided at one end of the temple leg 1 and extending outward, a connecting notch 4 provided on the temple head 3 and matched with the connecting protrusion 2, a positioning protrusion 5 penetrating through the connecting protrusion 2 and protruding outward on the upper and lower surfaces of the connecting protrusion 2, and a positioning through hole 6 provided on the inner wall of the temple head 3 and matched with the positioning protrusion 5 to keep the temple head 3 and the temple leg 1 connected, the positioning protrusion 5 is in interference fit with the temple head 3 to keep the positioning protrusion 5 in the positioning through hole 6.

[0033] ​​​​The connecting mechanism of the spectacle post and the temple of the present application is characterized in that a connecting protrusion is arranged at one end of the temple and extends outward, and cooperates with the connecting gap arranged on the spectacle post to form an installation position, and the connecting protrusion is provided with a positioning protrusion penetrating and protruding from the upper and lower surfaces of the connecting protrusion, and the inner wall of the spectacle post is provided with a positioning through hole for the positioning protrusion to be clamped into, and when the positioning protrusion is clamped into the positioning through hole in an interference fit manner, the temple and the spectacle post are connected immediately, the installation and disassembly process is simplified, the operation of using tools is avoided, the user experience is improved, and the overall appearance of the spectacle is more simple and beautiful due to the absence of exposed screws, the problem of poor opening and closing caused by rusting of the screws in the traditional design is avoided, and the service life of the spectacle is prolonged.

[0034] Further, as a preferred embodiment of the present application, the inner wall of the spectacle post 3 is provided with an installation slot 7 extending from the positioning through hole 6 to the direction close to the temple 1.

[0035] In the present embodiment, the installation slot 7 extending from the positioning through hole 6 to the direction close to the temple 1 is arranged to provide a channel for the positioning protrusion 5 to slide into the positioning through hole, so that the temple can be conveniently installed and dismounted with the spectacle post.

[0036] Further, as a preferred embodiment of the present application, the top surface of the installation slot 7 gradually inclines upward from the positioning through hole 6 to the direction close to the temple 1, and the bottom surface of the installation slot 7 gradually inclines downward from the positioning through hole 6 to the direction close to the temple 1.

[0037] In the present embodiment, the inclined top surface and bottom surface provide a guiding effect for the positioning protrusion 5, so that the positioning protrusion can extrude the upper and lower surfaces of the inner wall of the spectacle post outward during the sliding installation process, thereby achieving interference fit, and after the installation is completed, i.e. after the positioning protrusion is clamped into the positioning through hole, the temple is not easy to be disengaged from the installation slot relative to the spectacle post at any folding angle, thereby improving the user experience.

[0038] Further, as a preferred embodiment of the present application, the height of the positioning protrusion 5 is H, the maximum height of the installation slot 7 is B, and the height H of the positioning protrusion 5 is matched with the maximum height B of the installation slot 7.

[0039] In the present embodiment, when the height H of the positioning protrusion 5 is matched with the maximum height B of the installation slot 7, the positioning protrusion 5 can be smoothly and initially aligned with the installation slot 7, and the positioning operation can be quickly performed, and then the positioning protrusion is slid along the installation slot by pressing with external force and clamped into the positioning through hole 6 in an interference fit manner.

[0040] Further, as a preferred embodiment of the present solution but not as a limitation, the positioning protrusion 5 is in the shape of a circular arc polygon and has a minimum diameter D, and the mounting slot 7 has a width L, and the minimum diameter D of the positioning protrusion 5 is matched with the width L of the mounting slot 7.

[0041] In the present embodiment, the positioning protrusion 5 in the shape of a circular arc polygon ensures the structural strength, and through the accurate matching of the minimum diameter D and the width L of the mounting slot 7, the positioning protrusion can only be fitted into the mounting slot at a specific angle. This matching relationship avoids the problems of the positioning protrusion 5 being stuck due to being too tight or being shaken due to being too loose in the mounting slot 7, and ensures the flexible and stable connection between the temple 1 and the spectacle stem 3.

[0042] Further, as a preferred embodiment of the present solution but not as a limitation, the positioning through hole 6 is in the shape of a circle and has a diameter R, and the positioning protrusion 5 has a maximum diameter S, and the maximum diameter S of the positioning protrusion 5 is greater than the width L of the mounting slot 7 and is matched with the diameter R of the positioning through hole 6.

[0043] In the present embodiment, the positioning through hole 6 in the shape of a circle is matched with the maximum diameter S of the positioning protrusion 5, which ensures that the positioning protrusion 5 will not be loose after being fitted into the positioning through hole 6, thereby realizing the reliable connection between the temple 1 and the spectacle stem 3. Moreover, the positioning protrusion 5 is avoided from being stuck due to being too tight in the positioning through hole 6, thereby improving the overall durability of the glasses.

[0044] Further, as a preferred embodiment of the present solution but not as a limitation, the positioning protrusion 5 is in interference fit with the temple 1 when sliding along the mounting slot 7.

[0045] In the present embodiment, the interference fit ensures that the positioning protrusion 5 will not be loose or dislocated during the sliding process due to the gap of the mounting slot 7, thereby maintaining the stability of the connection between the temple 1 and the spectacle stem 3. This close fit relationship effectively prevents the temple 1 from accidentally sliding or falling off during use, thereby improving the reliability and durability of the glasses.

[0046] Further, as a preferred embodiment of the present solution but not as a limitation, the positioning through hole 6 partially penetrates the spectacle stem 3 upward and the positioning through hole 6 penetrates the spectacle stem 3 downward.

[0047] In the present embodiment, the design that the positioning through hole 6 partially penetrates the spectacle stem 3 upward and penetrates downward ensures the reliable connection between the positioning protrusion and the positioning through hole, and at the same time, the upper surface of the spectacle stem will not be punched, making the overall appearance of the glasses more simple, beautiful and atmospheric.

[0048] Further, as a preferred embodiment of the present solution but not as a limitation, the positioning through hole 6 is in the shape of an ellipse.

[0049] 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.

[0050] 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.

[0051] 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.

[0052] The working principle of this embodiment is as follows:

[0053] 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.

[0054] The above are implementation methods provided in conjunction with specific content, and it is not intended that the specific implementation of this application is limited to these descriptions. Any methods or structures that are similar to those of this application, or any technical deductions or substitutions made based on the concept of this application, should be considered within the scope of protection of this application.
