Technical Field

[0001] This utility model relates to the field of eyeglasses technology, specifically to eyeglasses with adjustable temple length. Background Technology

[0002] Eyeglasses are a combination of lenses and frames, used to improve vision, protect the eyes, or for decorative purposes.

[0003] When eyeglass frames are manufactured, the temples are generally of a fixed length. The sides can be squeezed and moved, but the length cannot be adjusted. They can only fit the specific person, and in most cases, the frames will be too long or too short, which limits their applicability and brings a bad wearing experience.

[0004] Therefore, a type of eyeglass with adjustable temple length is proposed to solve the problems mentioned above. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example: Please see Figure 1 - Figure 8 The eyeglasses with adjustable temple length in this embodiment include a frame 1; The front temple 2 is located on opposite sides of the frame 1 and is rotatably connected to the inner end of the frame 1. A insertion groove 201 is provided in the middle of the end of the front temple 2 away from the frame 1. The middle temple 3 is located on opposite sides of the frame 1 and is inserted into the front temple 2. A connecting strip 6 is fixedly connected to the side near the front temple 2 and is inserted into the connecting groove 201. The inner wall of the insertion slot 201 is provided with a positioning head 5, and the outer side of the insertion strip 6 is provided with several positioning grooves 601, with the positioning head 5 inserted into the positioning groove 601. First, the rotating connection between the frame 1 and the temple 2 is the conventional way of connecting existing eyeglass temples, so it is not described in detail here; The insertion guide of the insertion strip 6 through the insertion slot 201 allows for accurate adjustment of the connection distance between the front leg 2 and the middle leg 3 of the mirror. Specifically, the positioning head 5 is inserted into the positioning groove 601, and the insertion strip 6 is stretched or pushed to allow the positioning head 5 to be inserted into the positioning groove 601 at different locations, thus achieving the effect of positioning the insertion strip 6 after the distance is adjusted. This allows for adjustment of different usage lengths of the middle leg 3 of the mirror, improving the applicability of the device.

[0020] Please see Figure 6 - Figure 9 The positioning head 5 is composed of a cylindrical part and a hemispherical part, and is an integral structure. The inner wall of the mirror front leg 2 is provided with a positioning groove 202 for the cylindrical part of the positioning head 5 to be inserted and fixed. The positioning head 5 is inserted into the positioning groove 601 through the hemispherical part. The curvature of the lower surface of the positioning head 5 is consistent with the curvature of the positioning groove 601. There are several positioning grooves 601, and two adjacent positioning grooves 601 are connected, and the several positioning grooves 601 are linearly distributed; A stop 203 is installed on the inner wall of the front temple 2 of the mirror. The stop 203 is located below the positioning groove 202 and is close to the outlet end of the insertion groove 201. A sliding groove 603 is provided on the outer side of the connector strip 6. The sliding groove 603 is located in a corresponding position to the positioning groove 601. A limiting protrusion 602 is provided inside the sliding groove 603. By setting the positioning head 5 to a material with a certain degree of flexible deformation, such as rubber, and setting the size of the cylindrical part of the positioning head 5 to be larger than the positioning groove 202, the positioning head 5 has an automatic positioning effect when it is inserted into the positioning groove 202, thus ensuring accurate and tight installation of the positioning head 5. By setting several positioning grooves 601 to be continuously distributed, the inner hemispherical part of the positioning head 5 can always be in contact with the positioning groove 601. With the full contact of the arc-shaped parts of the two components, the positioning head 5 is accurately positioned in the positioning groove 601. Under the deformation support of the positioning head 5 itself, the insertion strip 6 can retract inward when pulled outward or pushed inward, so that the insertion strip 6 moves smoothly. Then, under the natural reset of the positioning head 5, the effect of accurate positioning with the positioning groove 601 is formed. Secondly, the stop block 203 provides guiding support for the movement of the slide 603, and the limiting protrusion 602 and the stop block 203 limit the movement distance of the connector 6, preventing the connector 6 from moving too far, causing the positioning head 5 to lose contact with the positioning groove 601, and the connector 6 to move out of the connector groove 201, thus ensuring the reliability of the connection distance between the middle leg 3 and the front leg 2 of the mirror.

[0021] Please see Figure 5The middle leg 3 is rotatably connected to the rear leg 4 at the end away from the front leg 2. The rear leg 4 is inserted into the middle leg 3. A rotating component 7 is provided at the insertion position of the middle leg 3 and the rear leg 4. The rotating assembly 7 includes a rotating rod 701, a toothed gear 702, a connector 703, a spring 704, and a rotating shaft 705; The rotating rod 701 is fixedly installed at one end of the rear leg 4 of the mirror. The connector 703 is threadedly connected to the inside of the middle leg 3 of the mirror. The spring 704 is built into the inside of the middle leg 3 of the mirror, and one end of the spring 704 is fixed to the spring 704. The rotating shaft 705 is installed through the side of the rotating rod 701. The rotating shaft 705 is rotatably installed inside the rear leg 4 of the mirror. The teeth 702 are distributed in an arc shape and mesh with the end of the connector 703. Supported by the rotating component 7, the rear temple 4 and the middle temple 3 of the mirror can be rotated and adjusted. By rotating the angle of the rear temple 4, it can be hung on the ear, which plays a certain role in positioning and support, and improves the reliability and stability of the device when worn. Specifically, when the rear leg 4 of the mirror is rotated, under the axial support of the rotating shaft 705, the meshing tooth 702 engages with the connector 703 and rotates, pushing the connector 703 to move inward, causing the spring 704 to be compressed and retracted. When the rear leg 4 of the mirror is rotated to the accurate position, under the elastic reset of the spring 704, the connector 703 is pushed to move outward, pushing the connector 703 to contact and engage with the meshing tooth 702, forming a positioning connection effect, ensuring the convenience of adjusting the rear leg 4 and the middle leg 3 of the mirror and the stability after adjustment; The connector 703 has a groove on its end side that engages with the tooth 702, ensuring the precision of the tooth 702 during rotation. Based on the contact limit between the inner leg 3 and the outer leg 4, it limits the rotation range of the outer leg 4, preventing excessive rotation stroke and ensuring the usability of the outer leg 4.

[0022] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. As long as they can achieve their beneficial effects, they can be implemented. Therefore, this embodiment will not elaborate on their specific structural composition and working principle.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
