Description

Technical Field

[0001] The utility model relates to the field of glasses, in particular to a temple locking structure of glasses. Background Art

[0002] Regardless of their application, the basic structure of various types of glasses is that lenses are placed in a frame, and screw holes are opened in the pivotal parts on both sides of the frame. The temples are screwed into the screw holes of the pivotal parts through screw fixing elements to complete the assembly of the glasses, allowing users to wear the temples on their ears and see through the lenses.

[0003] However, in actual use, it has been found that the temples are only pivotally connected to the pivotal parts of the frame by screw fasteners, which makes them prone to loosening after long-term use. This is especially true for glasses made of metal, or glasses with Bluetooth communication components, speakers, etc. installed on the temples. The weight of the glasses can more easily cause the screw fasteners at the pivotal parts of the temples and the frame to loosen and fall off. The loosened screw fasteners are relatively small in size and can be easily lost, making them extremely inconvenient to use. Utility Model Content

[0004] The purpose of the utility model is to provide a locking structure for the temples of spectacles, aiming to improve the problem that the temples of conventional spectacles are only pivotally connected to the pivotal connection portion of the frame by screw fixing elements, which is prone to loosening.

[0006] A temple locking structure for glasses, comprising a frame, temples and screw-fastening elements;

[0007] Corresponding pivotal parts are provided on both sides of the frame, each of which has a concave pivotal groove and a screw hole extending vertically therethrough;

[0008] The front end of the temple is provided with a pivot section corresponding to the pivot slot, the pivot section is inserted into the pivot slot, and the pivot section is provided with a pivot hole corresponding to the screw hole;

[0009] The screw-fixing element is inserted into the screw hole and the pivot hole. The bottom end of the screw-fixing element protrudes from the lower end of the screw hole and is fixed with a fixing piece.

[0010] Furthermore, the screw-fixing element includes an inserting portion and a limiting portion fixed at one end of the inserting portion, the inserting portion is inserted into the screw hole and the pivot hole, the other end of the inserting portion protrudes from the lower end opening of the screw hole, and the limiting portion presses against the upper end opening of the screw hole.

[0011] Furthermore, a clearance groove is provided on the pivotal portion, and the clearance groove is located at the upper end opening of the screw hole. The limiting portion is embedded in the clearance groove, and the top surface of the limiting portion is flush with the top surface of the pivotal portion.

[0012] Furthermore, the plug-in portion is provided with a cylindrical segment and a threaded segment, the cylindrical segment corresponds to the position of the pivot hole, the threaded segment is located below the cylindrical segment, an internal thread is provided on the threaded segment, an internal thread is provided on the inner side wall of the screw hole, the internal thread is located below the pivot groove, and is connected to the external thread of the threaded segment.

[0013] Furthermore, the fixing member includes a nut, which is fixed at the bottom end of the threaded section.

[0014] After adopting the above technical solution, the utility model has the following advantages compared with the background technology:

[0015] 1. By lengthening the screw-fixing element, the bottom end of the screw-fixing element is passed through the screw hole, and the end is fixedly connected to the nut. The screw-fixing element and the nut achieve a secondary locking effect, which not only makes it difficult for the temples to loosen, but also has a better restrictive effect on the temples.

[0030] Example

[0031] Referring to Figures 1-4, this embodiment provides a temple locking structure for glasses, comprising a frame 1, temples 2, and screw-fastening elements 3. The frame 1 has corresponding pivotal portions 11 on either side, each having an inwardly recessed pivot groove 111. Furthermore, the pivotal portions 11 have screw holes 112 extending vertically therethrough. In this embodiment, the notch of the pivot groove 111 faces the temple 2, the screw hole 112 passes through the pivot groove 111, and the direction in which the screw hole 112 extends is perpendicular to the direction in which the pivot groove 111 extends.

[0032] The front end of the temple 2 is provided with a pivot section 21 corresponding to the pivot slot 111. The pivot section 21 is inserted into the pivot slot 111. The pivot section 21 is provided with a pivot hole 211 corresponding to the screw hole 112. The pivot hole 211 is located in the extension direction of the screw hole 112. In this embodiment, the pivot hole 211 is connected to the screw hole 112, and the opening diameter of the pivot hole 211 and the screw hole 112 are equal.

[0033] The screw-fixing element 3 is inserted into the screw hole 112 and the pivot hole 211. The bottom end of the screw-fixing element 3 protrudes from the lower end of the screw hole 112 and is fixed with a fixing piece. In the present embodiment, the screw-fixing element 3 includes an inserting portion 31 and a limiting portion 32 fixed at one end of the inserting portion 31. The inserting portion 31 is inserted into the screw hole 112 and the pivot hole 211. The other end of the inserting portion 31 protrudes from the lower end opening of the screw hole 112. The limiting portion 32 abuts against the upper end opening of the screw hole 112. In the present embodiment, a clearance groove 113 is provided on the pivoting portion 11. The clearance groove 113 is located at the upper end opening of the screw hole 112. The limiting portion 32 is embedded in the clearance groove 113 so that the top surface of the limiting portion 32 is flush with the top surface of the pivoting portion 11, avoiding the formation of a protruding structure that affects the overall aesthetics. The limiting portion 32 is located at the upper end opening of the screw hole 112 to limit the insertion portion 31 and ensure the stability of the connection between the insertion portion 31 and the pivoting portion 11 and the pivoting section 21 .

[0034] In this embodiment, the plug-in portion 31 is provided with a cylindrical section 311 and a threaded section 312. The cylindrical section 311 corresponds to the position of the pivot hole 211. The threaded section 312 is located below the cylindrical section 311 and is provided with an internal thread. The inner side wall of the screw hole 112 is provided with an internal thread. The internal thread is located below the pivot groove 111 and is connected to the external thread of the threaded section 312. The side surface of the cylindrical section 311 is a smooth arc surface. When assembled, the cylindrical section 311 is located within the pivot hole 211 of the pivot section 21, which facilitates the rotation of the temple 2 and reduces the friction force applied to the temple 2 by the screw-fixing element 3. The internal thread is provided below the pivot groove 111 and is threadedly connected to the external thread of the threaded section 312, effectively improving the firmness of the connection between the temple 2 and the frame 1, while also increasing the friction between the screw-fixing element 3 and the frame 1, preventing the screw-fixing element 3 from loosening. In this embodiment, the fixing member includes a nut 4, which is fixed to the bottom end of the threaded section 312. The top surface of the nut 4 abuts against the pivot portion 11, limiting the position of the screw-fastening element 3. The nut 4 also abuts against the pivot portion 11 to provide a secondary locking mechanism between the frame 1 and the temple 2, preventing the temple 2 from loosening during use. This also improves the locking effect of the temple 2, ensuring good stability during rotation. Similarly, fixing members with other structures can be provided to secure the screw-fastening element.

[0035] In this embodiment, by lengthening the screw-fixing element 3, the bottom end of the screw-fixing element 3 is fixedly connected to the nut 4 after passing through the screw hole 112, and the screw-fixing element 3 and the nut 4 achieve a secondary locking effect, which not only makes it difficult for the temple 2 to loosen, but also has a better restrictive effect on the temple 2.

[0036] In this embodiment, after the glasses are worn for a long time, if the screw-fastening element 3 between the temple 2 and the frame 1 becomes loose, the screw-fastening element 3 and the nut 4 can be re-matched and locked together to facilitate the installation and repair between the temple 2 and the frame 1, thereby greatly extending the service life of the glasses.

[0037] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
