Description

Technical Field

[0001] This utility model relates to the field of eyeglasses, specifically to a pair of sunglasses with easily replaceable lenses. Background Technology

[0002] Sunglasses (also known as sunglasses or tinted glasses) are a type of eyewear with a special coating on the lenses. Their main function is to protect the eyes from strong light and ultraviolet rays, while also reducing glare and improving visual comfort and clarity.

[0003] With the technological advancements in sunglasses and the improvement of consumers' spending and aesthetic standards, sunglasses lenses have evolved from the traditional black to a variety of colors to meet different visual experiences and applicable scenarios, such as gray, brown, and green.

[0004] However, consumers have to buy multiple pairs of glasses to meet their needs for various colored lenses, which increases their financial burden. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide sunglasses with interchangeable lenses that can be quickly replaced with different colored lenses as needed.

[0006] To achieve the above objectives, this utility model provides the following technical solution: It includes eyeglass frames located on the left and right sides respectively, a bridge of the nose fixedly disposed between the left and right eyeglass frames, a through-hole and a lens installed within the eyeglass frame, and a temple hinged to the other side of the eyeglass frame opposite to the other eyeglass frame. The key feature is that the through-hole comprises a front part and a rear part from front to back; the rear part has a limiting step along its edge that abuts against the rear of the lens; the front part has an extension area extending to the bridge of the nose; a knob groove is provided at the edge of the extension area; a limiting notch is provided at the position corresponding to the knob groove on the front edge of the lens; a knob is provided for rotation of the bridge of the nose; an operating protrusion for manually rotating the knob is provided in front of the knob; when the knob is rotated, it has a fixed state for the lens located in front of the limiting notch and a disassembled state for the lens located in the knob groove.

[0007] By adopting the above technical solution, when it is necessary to install lenses, first rotate the knob to the lens disassembly position, and the lens can be inserted into the lens hole. Then, rotate the knob to the lens fixing position to fix the lens in the lens hole, completing the quick lens installation. When it is necessary to remove lenses, simply rotate the knob to the lens disassembly position to push the lens out from the back of the lens hole. The above structure has the following advantages: ① The frame has the function of replacing lenses. When purchasing lenses, users only need to purchase a single frame and multiple modular lenses of different colors to meet the needs of multiple colored lenses, without having to purchase multiple pairs of sunglasses, greatly reducing the consumer's financial burden and providing the possibility of expanding to new colored lenses in the future; ② When consumers need to change to different colored lenses due to changes in usage scenarios, they can simply rotate the knob to install or remove different colored lenses, and the operation does not require professional tools, making the operation faster and more convenient.

[0008] The present invention is further configured such that: the bridge of the nose is provided with an alignment post at the junction of the extension area and the knob groove in the front-back direction; the knob is provided in a fan shape on the outer peripheral surface of the front end of the alignment post; and the lens is provided with a semi-circular hole at the edge behind the limiting notch in the front-back direction that fits against the outer peripheral surface of the alignment post.

[0009] By adopting the above technical solution, in addition to using the alignment post as the installation position of the knob, its arc-shaped outer peripheral surface is reasonably used in conjunction with the semi-circular hole to align the lens, making the structure more streamlined.

[0010] The present invention is further configured such that the cross-section of the knob groove and the limiting notch is a semi-circle with the inner diameter being the same as the outer diameter of the knob.

[0011] By adopting the above technical solution, the knob groove and the limiting notch are combined to form a circular rotation space with an inner diameter that is the same as the outer diameter of the knob, which serves as the rotation guide structure for the knob, making the rotation of the knob more stable.

[0012] The present invention is further configured such that: an elastic filling layer is provided behind the knob to fill the gap between the knob and the limiting notch.

[0013] By adopting the above technical solution, an elastic filling layer is added to fill the gap between the knob and the limiting notch after the knob is positioned in front of the limiting notch, ensuring that the lens is reliably positioned within the frame and will not vibrate.

[0014] The present invention is further configured such that: the nose bridge is provided with a rotating hole with a diameter smaller than the outer diameter of the alignment post behind it; the rear end of the alignment post is coaxially provided with a rotating shaft that rotates with the rotating hole and has a length smaller than the rotating hole; the rear end of the rotating shaft is coaxially provided with an adjusting screw extending to the rear of the nose bridge; the adjusting screw is fitted with an elastic damping ring that abuts against the rear of the nose bridge; an adjusting plate is provided behind the nose bridge; and an adjusting screw hole that threadedly engages with the adjusting screw is provided in front of the adjusting plate.

[0015] By adopting the above technical solution, the installation of the rotating shaft and the adjusting plate is achieved by adjusting the adjusting screw and adjusting the adjusting screw hole. On the one hand, it makes the disassembly and assembly of the knob and the nose bridge more convenient. On the other hand, by rotating the adjusting plate, the compression degree of the elastic damping ring is adjusted, thereby controlling the rotation damping of the knob, so that the knob can be stably maintained after being rotated to the position. If the knob does not need to be adjusted for a long time, the adjusting plate can be completely tightened to the locked state.

[0016] The present invention is further configured such that: an auxiliary alignment post is provided extending forward at the diagonal of the limiting step relative to the bridge of the nose; the lens is provided with an auxiliary alignment hole for the auxiliary alignment post to pass through; and both the auxiliary alignment post and the alignment post are provided with a frustum-shaped guide block extending to the front of the frame, with the smaller end of the frustum-shaped guide block facing forward.

[0017] By adopting the above technical solution, in addition to the first alignment structure formed by the alignment post and the semi-circular hole, the auxiliary alignment post and the auxiliary alignment hole form a second alignment structure, so that the lens inserted into the lens hole will not be misaligned. In addition, the frustum-shaped guide block guides the lens to the alignment post and the auxiliary alignment post from outside the lens frame, making the alignment process more convenient and faster.

[0027] like Figure 1 — Figure 7 As shown, this utility model discloses a pair of sunglasses with easily replaceable lenses, including frames 1 located on the left and right sides respectively, a nose bridge 2 fixedly disposed between the left and right frames 1, a lens hole 3 extending through the front and back of the frame 1 and a lens 4 installed in the lens hole 3, and temples 5 hinged to the other side of the frame 1 opposite to the other frame 1. The lens hole 3 includes a front part 31 and a rear part 32 from front to back. The rear part 32 has a limiting step 321 along its edge that abuts against the rear of the lens 4. The front part 31 has an extension area 311 extending to the nose bridge 2. A knob groove 312 is provided at the edge of the extension area 311. A limiting notch 41 is provided at the position of the front edge of the lens 4 corresponding to the knob groove 312. A knob 6 is rotatably disposed on the nose bridge 2. An operating protrusion 68 for manually rotating the knob 6 is provided in front of the knob 6. When the knob 6 is rotated, it has a fixed state for the lens located in front of the limiting notch 41 and a disassembled state for the lens located in the knob groove 312. Figure 2The knob 6 on the left is in the lens removal position, and the knob 6 on the right is in the lens fixing position. When installing lens 4, first rotate knob 6 to the lens removal position, and lens 4 can be inserted into lens hole 3. Then, rotate knob 6 to the lens fixing position to fix lens 4 in lens hole 3, completing the quick installation of lens 4. When removing lens 4, simply rotate knob 6 to the lens removal position to push lens 4 out from behind lens hole 3. The above structure has the following advantages: ① The frame has the function of replacing lens 4. When purchasing lens 4, users only need to purchase a single frame and multiple modular lenses 4 of different colors to meet the needs of multiple colored lenses 4, without having to purchase multiple pairs of sunglasses, greatly reducing the consumer's financial burden and providing the possibility of expanding to new colored lenses 4 in the future; ② When consumers need to change to different colored lenses 4 due to changes in usage scenarios, they only need to rotate knob 6 to remove and install different colored lenses 4, and the operation does not require professional tools, making the operation faster and more convenient.

[0028] The bridge of the nose 2 is located at the junction of the extension area 311 and the knob groove 312, and is rotatably provided with an alignment post 61 in the front-back direction. The knob 6 is fan-shaped and located on the outer peripheral surface of the front end of the alignment post 61. The lens 4 is located at the edge behind the limiting notch 41 and is provided with a semi-circular hole 42 in the front-back direction that fits with the outer peripheral surface of the alignment post 61. In addition to serving as the mounting position for the knob 6, the alignment post 61 makes reasonable use of its arc-shaped outer peripheral surface in conjunction with the semi-circular hole 42 to align the lens 4, making the structure more streamlined.

[0029] The cross-section of the knob groove 312 and the limiting notch 41 is a semi-circle with the inner diameter of the knob 6 being the same as the outer diameter of the knob 6. The combination of the knob groove 312 and the limiting notch 41 forms a circular rotation space with the inner diameter of the knob 6 being the same as the outer diameter of the knob 6, which serves as a rotation guide structure for the knob 6, making the rotation of the knob 6 more stable.

[0030] An elastic filling layer 62 is provided behind the knob 6 to fill the gap between the knob 6 and the limiting notch 41. The addition of the elastic filling layer 62 fills the gap between the knob 6 and the limiting notch 41 after the knob 6 is limited in front of the limiting notch 41, ensuring that the lens 4 is reliably limited in the frame 1 and will not vibrate. In addition, the elastic filling layer 62 is preferably made of rubber.

[0031] The nose bridge 2 is provided with a rotating hole 21 behind the alignment post 61, the diameter of which is smaller than the outer diameter of the alignment post 61. A rotating shaft 63, which is rotatably engaged with the rotating hole 21 and whose length is shorter than the rotating hole 21, is coaxially provided at the rear end of the alignment post 61. An adjusting screw 64, extending to the rear of the nose bridge 2, is coaxially provided at the rear end of the rotating shaft 63. An elastic damping ring 65 is fitted onto the adjusting screw 64 and abuts against the rear of the nose bridge 2. An adjusting disc 66 is provided behind the nose bridge 2, and an adjusting screw threaded into the adjusting screw 64 is provided in front of the adjusting disc 66. Hole 67 is used to install the rotating shaft 63 and the adjusting plate 66 by means of adjusting screw 64 and adjusting screw hole 67. On the one hand, it makes it easier to disassemble and assemble the knob 6 and the nose bridge 2. On the other hand, by rotating the adjusting plate 66, the compression degree of the elastic damping ring 65 is adjusted, thereby controlling the rotational damping of the knob 6, so that the knob 6 can be stably held after being rotated to the position. If the knob 6 does not need to be adjusted for a long time, the adjusting plate 66 can be completely tightened to the locked state. In addition, the elastic damping ring 65 is preferably made of rubber.

[0032] An auxiliary alignment post 322 is provided at the diagonal of the limiting step 321 relative to the bridge of the nose 2. The lens 4 is provided with an auxiliary alignment hole 43 through which the auxiliary alignment post 322 passes. The front ends of the auxiliary alignment post 322 and the alignment post 61 are provided with a frustum-shaped guide block 323 extending to the front of the frame 1. The smaller end of the frustum-shaped guide block 323 faces forward. In addition to the first alignment structure formed by the alignment post 61 and the semi-circular hole 42, the auxiliary alignment post 322 and the auxiliary alignment hole 43 form a second alignment structure, so that the lens 4 inserted into the lens hole 3 will not be misaligned. In addition, the frustum-shaped guide block 323 guides the lens 4 to the alignment post 61 and the auxiliary alignment post 322 from outside the frame 1, making the alignment process more convenient and faster.
