Description

Technical Field

[0001] This utility model relates to the field of eyeglasses, and in particular to eyeglasses with lenses that are easy to install and remove. Background Technology

[0002] Eyeglasses are a common product in daily life. They can be divided into vision correction and protection types according to their function. Eyeglasses usually consist of a frame, lenses, and rotating temples. The frame is usually made of deformable metal or plastic in one piece. The edges of the lenses are embedded in the slots of the frame. Special tools are used to shrink the frame so that the frame and lenses fit tightly together, and then screws are tightened to fix it.

[0003] As the frame ages, its elasticity decreases, and the gap between the frame and the lens widens, causing the connection between the frame and the lens to loosen. This makes it very easy for the lens to fall off during subsequent use. Furthermore, after prolonged use, various stains will accumulate in the frame slots, making it difficult to disassemble the frame and lens for cleaning. Utility Model Content

[0004] The purpose of this invention is to provide eyeglasses with lenses that are easy to install and remove, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model proposes a pair of eyeglasses with easily detachable lenses, comprising a frame, temples, and lenses. The frame is semi-framed, and the inner side of the frame is recessed with a mounting groove adapted to the upper edge of the lens. The upper edge of the lens is detachably engaged in the mounting groove. A connecting beam extends downward from the middle of the frame, and a rotatable locking block is hinged to the lower end of the connecting beam. The locking block can be rotated to a locked state or an open state. When the locking block is rotated to the locked state, the lens is engaged in the groove enclosed between the mounting groove and the locking block. When the locking block is rotated to the open state, the lens can be detached from the frame.

[0006] Furthermore, the frame has a clearance notch in the middle, and the lens has a first limiting flange corresponding to the clearance notch along the upper edge of the middle.

[0007] Furthermore, the two sides of the frame are provided with a first limiting groove recessed inward at the bottom surface of the mounting groove, and the two sides of the lens are provided with a second limiting flange corresponding to the first limiting groove.

[0027] In this embodiment, refer to Figures 1 to 5 This utility model proposes a pair of glasses with easy-to-disassemble lenses, including a frame 1, temples 2 and lenses 3;

[0028] The frame 1 is semi-framed, and the temples 2 are hinged to both ends of the frame 1. The inner side of the frame 1 is recessed with a mounting groove 12 that matches the upper edge of the lens 3. The upper edge of the lens 3 is detachably engaged in the mounting groove 12. The frame 1 has a clearance notch 8 in the middle. The upper edge of the middle of the lens 3 has a first limiting flange 4 corresponding to the clearance notch 8. The two sides of the frame 1 are recessed with a first limiting groove 13 on the bottom surface of the mounting groove 12. The two sides of the lens 3 extend outward with a second limiting flange 5 corresponding to the first limiting groove 13. When the lens 3 is engaged in the mounting groove 12, the first limiting flange 4 is embedded in the clearance notch 8, and the second limiting flange 5 is embedded in the first limiting groove 13, thus limiting the left and right movement of the lens 3.

[0029] A connecting beam 10 extends downward from the middle of the frame 1. A rotating locking block 9 is hinged to the lower end of the connecting beam 10. The locking block can be rotated to a locked state or an open state. When the locking block 9 is rotated upward to the locked state, the lens 3 is engaged in the groove enclosed between the assembly groove 12 and the locking block 9. When the locking block 9 is rotated downward to the open state, the lens 3 can be detached from the frame 1.

[0030] The connecting beam 10 has a vertical structure with a certain width. When the lens 3 is engaged in the mounting groove 12, the front end face of the connecting beam 10 fits tightly against the middle of the lens 3, providing stable support for the lens 3. The depth and width of the mounting groove 12 match the upper edge of the lens 3. The inner wall of the mounting groove 12 restricts the movement of the lens 3 in the front-back direction. Combined with the support of the connecting beam 10, the lens 3 can be limited from both the front and back directions.

[0031] The locking block 9 includes a hinge part 16, a support part, and a locking part 17. The hinge part 16 is hinged to the lower end of the connecting beam 10 via a damping pivot. There is damping at the hinge point between the hinge part 16 and the connecting beam 10. The locking block 9 will not loosen without external force, ensuring smooth rotation of the locking block 9 while providing stable support when the locking block 9 is rotated to the designated position.

[0032] The support part is located between the hinge part 16 and the locking part 17. The lower edge of the middle part of the lens 3 is provided with a limiting recess 6. The upper end surface of the support part is provided with an arc-shaped support surface 15 that matches the limiting recess 6. The locking part 17 and the connecting beam 10 form a second limiting groove 14 that matches the thickness of the lower edge of the lens 3. When the locking block 9 is flipped to the locked state, the upper edge of the lens 3 is engaged in the assembly groove 12, and the lower edge of the middle part of the lens 3 is engaged in the second limiting groove 14. The limiting recess 6 and the support surface 15 are tightly fitted to limit the upper and lower movement of the lens 3.

[0033] The limiting recess 6 is provided with a limiting hole 7 that passes through the lens above it. The inner side of the locking part 17 is provided with a limiting protrusion 6 corresponding to the limiting hole 7. When the locking block 9 is flipped to the locking state, the limiting protrusion 6 is embedded in the limiting hole 7, which further enhances the stability of the connection between the lens 3 and the frame 1.

[0034] The working principle of this embodiment is as follows:

[0035] First, the temple 2 is hinged to both ends of the frame 1. The locking block 9 is flipped downwards to the open state, and the upper edge of the lens 3 is engaged in the mounting groove 12. The first limiting flange 4 is embedded in the clearance notch 8, and the second limiting flange 5 is embedded in the first limiting slot 13. After confirming that everything is correct, the locking block 9 is flipped upwards to the locked state. The limiting protrusion 6 is embedded in the limiting hole 7, and the limiting recess 6 is tightly fitted with the support surface 15. This completes the stable installation of the lens 3. When it is necessary to clean or replace the lens 3, simply flip the locking block 9 downwards to the open state to detach the lens 3 from the frame 1, making the installation and removal of the lens 3 convenient and quick.

[0036] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
