Description

Technical Field

[0001] The utility model belongs to the technical field of sunglasses and relates to adjustable sunglasses. Background Art

[0002] Sunglasses, also known as sun visors, are used for sun protection and are typically composed of lenses, frames, and nose pads. Since sunglasses can only be worn alone, this poses a significant problem for those who already wear glasses. Therefore, there is a need for adjustable sunglasses that combine sunglasses with glasses to accommodate different needs.

[0003] Chinese patent CN218917844U discloses an adjustable pair of sunglasses comprising a daily support frame, replaceable lenses, an eye support frame, ear support legs, a sunglasses adjustment structure, a sunglasses frame, and sunglasses lenses, wherein: the replaceable lenses are embedded in the interior of the daily support frame, and the eye support frame is mounted on both ends of the daily support frame by snaps, and the ear support legs are embedded in the rear end of the eye support frame; the sunglasses adjustment structure is nested in the surface of the eye support frame, and the sunglasses frame is welded to one end of the sunglasses adjustment structure, and the sunglasses lenses are nested in the interior of the sunglasses frame.

[0004] The sunglasses use a stretching support rod within the sunglass adjustment mechanism to pull the sunglass frame outward. The frame is then rotated upward via a rotating shaft and a supporting rotating base until it is positioned above the forehead, freeing the normal support frame from obstructing vision. Consequently, after the sunglass frame is rotated upward, one end of the stretching support rod extends downward, positioning itself at the wearer's eyes. This can easily cause the wearer to bump into the stretching support rod and displace it when rubbing their eyes or holding the temples, requiring readjustment. This is inconvenient.

[0005] In order to solve the above problems, the utility model provides a pair of adjustable sunglasses. Utility Model Content

[0006] In order to solve the problems existing in the background technology, the utility model proposes a pair of adjustable sunglasses.

[0007] In order to achieve the above-mentioned object, the technical solution adopted by the present invention is as follows: comprising a frame, wherein one side of the frame is symmetrically connected to two first rotating shafts, the ends of the two first rotating shafts are fixedly provided with a first lens, and a second lens is rotatably provided on one side of each first lens;

[0008] One side of the frame is rotatably connected to a connecting shaft, the connecting shaft is located between the two first rotating shafts, and both ends of the connecting shaft are provided with transmission assemblies, which respectively cooperate with the corresponding first rotating shafts. When the connecting shaft rotates, the transmission assembly drives the corresponding first rotating shaft to rotate;

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] like Figures 1-6 As shown, the technical solution adopted by the present invention is as follows: an adjustable pair of sunglasses comprising a frame 1, with temples 2 hingedly connected to both ends of the frame 1, and temples 2 fixedly connected to the ends of each temple 2. The temples 3 are used to alleviate the user's ear discomfort, reducing the discomfort caused by prolonged wear, and the temples 3 are non-slip, which can prevent the user from slipping due to movement during wear.

[0031] One side of the frame 1 is symmetrically rotatably connected to two first rotating shafts 5 , and the ends of the two first rotating shafts 5 are fixedly provided with first lenses 12 .

[0032] The end of each first rotating shaft 5 is fixedly connected to a first connecting plate 11 , and the first lens 12 is fixedly connected to the bottom of the corresponding first connecting plate 11 .

[0033] One side of the frame 1 is rotatably connected to a connecting shaft 9, which is located between the two first rotating shafts 5. The connecting shaft 9 is arranged horizontally.

[0034] Two symmetrical mounting plates 8 are fixedly connected to one side of the frame 1. A connecting shaft 9 rotates through the two mounting plates 8. Both mounting plates 8 are located between the two first rotating shafts 5. The two mounting plates 8 position the connecting shaft 9.

[0035] Both ends of the connecting shaft 9 are provided with transmission assemblies, which respectively cooperate with the corresponding first rotating shaft 5. When the connecting shaft 9 rotates, the transmission assembly drives the corresponding first rotating shaft 5 to rotate.

[0036] The transmission assembly includes a second bevel gear 7, which is fixedly connected to the end of a connecting shaft 9. A first bevel gear 6 is fixedly mounted on each first rotating shaft 5, and each second bevel gear 7 meshes with the corresponding first bevel gear 6. Rotation of the connecting shaft 9 drives the two second bevel gears 7, which in turn drive the corresponding first bevel gears 6, resulting in synchronous rotation of the two first rotating shafts 5.

[0037] A plurality of anti-slip strips 10 are evenly fixedly connected to the outer surface of the middle portion of the connecting shaft 9, and the plurality of anti-slip strips 10 are all located between the two mounting plates 8. The user can rotate the connecting shaft 9 by moving the anti-slip strips 10.

[0038] Two grooves 20 are symmetrically defined on the outer surfaces of both ends of the connecting shaft 9, each with a retaining slot 18 in the middle. Two spring locating pins 19 are symmetrically fixed to one side of the frame 1, one end of each spring locating pin 19 being retained within the corresponding retaining slot 18. After the connecting shaft 9 is rotated, one end of the spring locating pin 19 engages within the corresponding retaining slot 18, securing the connecting shaft 9 in place.

[0039] A second lens 15 is rotatably provided on one side of each first lens 12 .

[0040] The top of each first connecting plate 11 is fixedly connected to a second connecting plate 13, one side of each second connecting plate 13 is rotatably connected to a second rotating shaft 14, and a second lens 15 is fixedly connected to one end of the corresponding second rotating shaft 14. The second lens 15 can rotate.

[0041] A magnetic plate 16 is fixedly connected to the top of each first lens 12, with each magnetic plate 16 corresponding to the second rotation axis 14. Two magnetic blocks 17 are fixedly connected to the side of each second lens 15 closest to the first lens 12. The two magnetic blocks 17 on one side of the second lens 15 are symmetrical about the corresponding second rotation axis 14. There is an attractive force between the magnetic plates 16 and the corresponding magnetic blocks 17. After the second lens 15 is rotated, the appropriate magnetic block 17 is rotated to the side of the magnetic plate 16, and the attractive force secures the magnetic block 17 to the side of the magnetic plate 16, thereby securing the second lens 15 to the side of the first lens 12.

[0042] The first lens 12 is a myopia lens, and the second lens 15 is a sun lens.

[0043] The bottom of one side of the mirror frame 1 is fixedly connected to two mirror holders 4, and the first lens 12 and the second lens 15 are both slidably arranged on the top of the mirror holder 4. The mirror holder 4 has the function of supporting the first lens 12 and the second lens 15.

[0044] Working principle:

[0045] During use, the connecting shaft 9 is moved by the anti-slip strip 10, causing the connecting shaft 9 to rotate, driving the two second bevel gears 7 to rotate. The second bevel gears 7 drive the corresponding first bevel gears 6 to rotate, causing the two first rotating shafts 5 to rotate synchronously. This in turn drives the two first connecting plates 11 to rotate, causing the first lens 12 and the second lens 15 to rotate together.

[0046] If myopia lenses are needed, the first lens 12 is rotated to one side of the frame 1 so that the second lens 15 is located above the frame 1. If only sun lenses are used, the second lens 15 is rotated to one side of the frame 1 so that the first lens 12 is located above the frame 1. The first lens 12 and the second lens 15 are aligned vertically.

[0047] When the connecting shaft 9 rotates, it pushes one end of the spring positioning pin 19, causing the spring positioning pin 19 to retract. After the connecting shaft 9 is rotated to a suitable position, one end of the spring positioning pin 19 extends, causing one end of the spring positioning pin 19 to be locked into the corresponding locking groove 18, thereby positioning the connecting shaft 9 and fixing the positions of the first lens 12 and the second lens 15.

[0048] If it is necessary to use a myopia lens and a sun lens together, after the first lens 12 is rotated to one side of the frame 1 , the second lens 15 is positioned directly above the first lens 12 .

[0049] The second lens 15 is rotated downward, driving the second rotating shaft 14 to rotate on the side of the second connecting plate 13 until the second lens 15 is rotated to the side of the first lens 12. Simultaneously, the second lens 15 drives the magnets 17 to rotate, and the appropriate magnet 17 is rotated to the side of the magnetic plate 16. Magnetic attraction secures the magnet 17 to the side of the magnetic plate 16, thereby securing the second lens 15. This allows the wearer to use the first lens 12 and the second lens 15 together.

[0050] After adjustment, the foot cover 3 is hung on the ear for use.

[0051] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
