Description

Technical Field

[0001] This application relates to the field of eyeglasses, and more particularly to eyeglasses with easily replaceable lenses. Background Technology

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

[0003] In existing technology, eyeglass frames include temples and a frame, with lenses detachably connected to the frame; specifically, the lenses are directly clipped into the frame. In daily life, different lenses are typically needed for different scenarios, such as wearing sunglasses outdoors on a sunny day or 3D glasses when watching a 3D movie. However, when these glasses require lens replacement to meet different usage needs, the lenses must be pushed out of the frame, making the lens replacement difficult and potentially damaging. Utility Model Content

[0004] To improve the ease of lens replacement and protect the lenses, this application provides eyeglasses with lenses that are easy to replace.

[0005] This application provides a pair of eyeglasses with convenient lens replacement, employing the following technical solution:

[0006] A pair of glasses with easy-to-change lenses includes a frame and a lens assembly. The frame includes a mounting bracket and temples rotatably mounted on the mounting bracket. The lens assembly includes a lens rim and a lens snapped into the lens rim. Both the lens rim and the mounting bracket are provided with a connecting structure, and the lens rim and the mounting bracket are detachably connected through the connecting structure.

[0007] By adopting the above technical solution, when it is necessary to replace the lens to adapt to different usage scenarios, the lens assembly can be removed and replaced. That is, the lens ring and the lens are removed from the mounting frame and other lens rings are installed, without having to squeeze the lens out of the frame and then insert other lenses. Through the detachable connection structure between the lens ring and the mounting frame, the entire lens assembly (including the lens ring and the lens) can be replaced quickly, avoiding the lens damage problem that is easily caused when traditional glasses require the lenses to be removed separately, and significantly improving the convenience and safety of lens replacement.

[0008] Optionally, the mounting bracket has a slot extending along the height direction of the lens for inserting the lens ring on its surface, and the connecting structure is provided on the slot wall and the outer surface of the lens ring.

[0009] By adopting the above technical solution, slots are opened on the mounting frame for lens ring insertion, allowing the lens ring to be set into a fully enclosed structure. This reduces the risk of the lens falling off the lens ring after the lens assembly is removed from the mounting frame, providing better protection for the lens. Furthermore, the slot design on the mounting frame provides precise insertion guidance and limiting support for the lens ring, making the connection between the lens assembly and the frame more stable and reliable. At the same time, it simplifies the replacement process and reduces the risk of installation deviation.

[0010] Optionally, the connection structure includes a protrusion on the outer surface of the lens ring and a locking hole on the groove wall of the slot, the locking hole for inserting the protrusion, and the protrusion and the lens ring are arranged in a direction perpendicular to the direction in which the lens ring is inserted into the slot.

[0011] By adopting the above technical solution, the transverse locking structure of the protrusion and the locking hole (arranged perpendicular to the insertion direction) forms a mechanical lock after the lens ring is inserted into the slot, effectively preventing the lens assembly from accidentally falling off. The locking structure is simple, easy to process, and has a good connection effect.

[0012] Optionally, the protrusion and the lens ring are arranged in a direction perpendicular to the arrangement direction of the two lenses, and the protrusion and the locking hole are located between the two lenses.

[0013] By adopting the above technical solution, the protrusion and the locking hole are set between the two lenses, making full use of the space in the bridge of the glasses to achieve a hidden locking connection. This not only avoids the exposed structure from affecting the aesthetics, but also ensures that the locking point is subjected to balanced force, thereby improving the symmetry and stability of the connection.

[0014] Optionally, the protruding surface is formed with an installation arc surface and a disassembly arc surface, the installation arc surface being used to slide against the mounting bracket, and the disassembly arc surface being used to slide against the wall of the slot.

[0015] By adopting the above technical solution, the separate functional design of the installation arc surface and the removal arc surface allows the mirror ring to be automatically guided and locked when inserted by sliding against the installation arc surface, and to be released by sliding against the removal arc surface in the opposite direction when disassembling, thus realizing an intuitive operation of "one-insert-lock, one-push-remove", which is convenient to operate.

[0016] Optionally, the curvature of the mounting arc surface is less than the curvature of the disassembly arc surface.

[0017] By adopting the above technical solution, the smaller curvature of the installation surface facilitates smooth sliding and reduces insertion resistance; the larger curvature of the disassembly surface creates a steep unlocking path, requiring greater disassembly force to avoid accidental dislodgement, thus achieving a balance between convenience and anti-dislodgement.

[0018] Optionally, the connection structure further includes a protruding corner on the outer surface of the lens ring and a slot on the groove wall of the slot, wherein the slot is for inserting the protruding corner, and the protruding corner and the lens ring are arranged in a direction perpendicular to the direction in which the lens ring is inserted into the slot.

[0019] By adopting the above technical solution, the lateral snap-fit ​​between the convex corner and the slot serves as a supplementary or alternative solution, providing multiple locking points and enhancing the torsional resistance of the lens assembly. It is particularly suitable for the sides of eyeglasses where the stress is greater. The snap-fit ​​structure is simple, easy to process, and has a good connection effect.

[0020] Optionally, the convex corner and the slot are provided in two sets, and the two sets of convex corner and slot are respectively located on the opposite side of the two lenses.

[0021] By adopting the above technical solution, two sets of convex corners and slots are respectively set on the outer side of the two lenses to form a symmetrical locking structure, which disperses the stress concentration at the edge of the lens ring, effectively prevents connection failure caused by unilateral force, and improves the support strength of large-size lenses.

[0022] Optionally, the connecting structure further includes a groove formed on the surface of the lens ring and connected to the convex corner. The groove and the convex corner are arranged along the direction of insertion of the lens ring into the slot. The surface of the convex corner away from the groove is the insertion surface, and the surface shared by the convex corner and the groove is the exit surface. The connecting structure further includes a protrusion provided on the slot wall of the slot for insertion into the groove. The surface of the protrusion has an insertion arc surface and an exit arc surface. The insertion arc surface is used to slide against the insertion surface, and the exit arc surface is used to slide against the exit surface.

[0023] By adopting the above technical solution, the groove and the protrusion cooperate to form a two-stage locking in the depth direction of the slot. The separate functional design of the inserting arc surface and the exiting arc surface allows the lens ring to be automatically guided and locked when inserted by sliding the inserting surface against the inserting arc surface. When disassembling, the lens ring is released by sliding the exiting surface against the exiting arc surface in the opposite direction. This achieves an intuitive operation of "one-insert lock, one-push release", making it convenient to operate.

[0024] Optionally, the curvature of the inserted arc surface is less than the curvature of the exit arc surface.

[0025] By adopting the above technical solution, the small curvature of the inserted arc surface reduces assembly resistance, while the large curvature of the withdrawn arc surface increases the difficulty of disassembly. This facilitates assembly while ensuring a stable connection during use. A certain amount of force is required for disassembly to prevent accidental separation.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. It enables quick replacement of the entire lens assembly, avoiding the lens damage that can easily occur when traditional glasses require individual lens removal, significantly improving the convenience and safety of lens replacement;

[0028] 2. The snap-fit ​​structure forms a mechanical lock after the lens ring is inserted into the slot, effectively preventing the lens assembly from accidentally falling off. The snap-fit ​​structure is simple, easy to process, and has a good connection effect.

[0029] 3. It is easy to assemble and ensures a stable connection during use. It requires a certain amount of force to disassemble to prevent accidental separation. Attached Figure Description
