Description

Technical Field

[0001] The utility model relates to the technical field of glasses, in particular to a pair of dimming glasses with lenses capable of being threadedly connected. Background Art

[0002] Glasses are a common household item, primarily used to protect the eyes or correct vision. They are a type of vision care product and come in a wide variety, including myopia glasses, reading glasses, and dimmer glasses. In brightly lit environments, the glare can cause discomfort, necessitating the use of dimmer glasses to reduce the brightness of the lenses, thereby preventing damage and facilitating clearer vision. In dimly lit environments, dimmer glasses can be worn to increase the brightness of the lenses, preventing the effects of dim light on vision and preventing myopia and astigmatism.

[0003] Currently, the most common dimming glasses on the market are photochromic glasses, which incorporate silver halide into the lenses, causing the color to change through a chemical reaction. When exposed to ultraviolet light outdoors, these glasses automatically undergo a chemical reaction, darkening to prevent eye irritation. Indoors or in areas with very low UV light, they automatically return to transparency. However, these glasses cannot meet the wearer's need for rapid light switching, and the precision of adjusting light intensity is poor. To address the challenges of existing technologies, researchers have conducted extensive research and proposed a variety of solutions.

[0004] For example, Chinese patent publication number CN210109488U, date of publication February 21, 2020, discloses a pair of dimming glasses comprising a glasses body, wherein the glasses body comprises a lens ring, a fixed lens unit, and a dynamic lens unit, wherein the fixed lens unit is assembled in the lens ring, and the dynamic lens unit is connected to the lens ring; the fixed lens unit comprises an optical lens and a polarizing structure, and the dynamic lens unit comprises a rotating ring and an optical lens and a polarizing structure installed in the rotating ring; the relative angle between the polarizing structure of the dynamic lens unit and the polarizing structure of the fixed lens unit is adjusted by rotating the rotating ring. The disadvantage is that the disassembly and assembly of the lens unit requires maintenance personnel to tighten / loosen the screws with the help of special tools, which makes the installation cumbersome and inconvenient. In order to solve the problems existing in the prior art, we have developed a pair of dimming glasses with lenses that can be threaded. Utility Model Content

[0005] The purpose of the present invention is to provide a pair of light-adjusting glasses with lenses that can be threadedly connected, so as to solve the problems raised in the above-mentioned background technology.

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions: a pair of dimming glasses with lenses that can be threadedly connected, comprising a nose bridge, two symmetrical frames welded to both ends of the nose bridge, a dimming lens unit, and temples hinged on the outer side walls of the frames, the dimming lens unit comprising a connecting unit, a fixed lens installed in the connecting unit, a rotating unit rotatably connected to the connecting unit, and a dynamic lens installed in the rotating unit, the outer wall of the connecting unit being threadedly connected to the inner wall of the frame.

[0007] Furthermore, the connecting unit includes a connecting ring whose outer wall is threadedly connected to the inner wall of the frame, and a first limiting ring is integrally provided at the end of the connecting ring away from the frame, and an annular boss is integrally provided along the circumference of the connecting ring at the angle between the outer wall of the connecting ring and the first limiting ring, and the annular boss abuts against the outer wall of the frame near the end of the connecting ring, and the rotating unit includes a rotating ring whose inner wall is fitted and slidably connected to the outer wall of the limiting ring, and a second limiting ring is integrally provided near the end of the rotating ring away from the frame, the inner wall of the second limiting ring is fitted and slidably connected to the outer wall of the annular boss, and the outer side wall of the second limiting ring is fitted and slidably connected to the outer wall of the frame, and the cross-sectional width of the second limiting ring is equal to the cross-sectional width of the annular boss.

[0008] Furthermore, the outer wall of the fixed lens and the outer wall of the dynamic lens are respectively fitted with the inner wall of the connecting ring and the inner wall of the rotating ring. The end of the fixed lens away from the dynamic lens is provided with a first fixing ring whose outer wall is threadedly connected to the inner wall of the connecting ring. The end of the dynamic lens away from the fixed lens is provided with a second fixing ring whose outer wall is threadedly connected to the inner wall of the rotating ring.

[0009] Furthermore, two plug-in blocks are symmetrically provided on the side wall of the second fixing ring close to the dynamic lens, and two slots for inserting the plug-in blocks are symmetrically provided on the outer wall of the dynamic lens.

[0010] Furthermore, a clamping groove is provided on the outer wall of the first fixing ring away from the dynamic lens and on the outer wall of the second fixing ring away from the fixed lens.

[0011] Furthermore, a paddle is provided on the outer wall of the first fixing ring away from the dynamic lens and on the outer wall of the second fixing ring away from the fixed lens.

[0012] Furthermore, a compression spring is sleeved on the outer wall of the annular boss, and both ends of the compression spring abut against opposite sides of the first limiting ring and the second limiting ring, and the cross-sectional width of the second limiting ring is less than the cross-sectional width of the annular boss.

[0013] Furthermore, the frame located outside the annular boss is evenly provided with positive ratchets along its circumference, and the outer wall of the second limiting ring close to the frame is evenly provided with reverse ratchets along its circumference, and the positive ratchets are engaged with the reverse ratchets.

[0015] 1. By setting a threaded connection between the frame and the dimming lens unit, the lens can be disassembled and assembled without the help of special workpieces.

[0016] 2. The components of the dimming lens unit are connected by threaded and socketed connections, so that the components can be installed and disassembled quickly and accurately, which improves production efficiency and provides convenience for users to replace lenses or components.

[0017] 3. The setting of the plug and the slot increases the connectivity between the second fixed ring and the dynamic lens, thereby preventing the connection between the dynamic lens and the rotating ring from loosening, resulting in the rotating ring being unable to drive the dynamic lens to rotate.

[0018] 4. The setting of the ball prevents the dynamic lens from fitting against the side wall of the first limiting ring, causing wear due to rotation.

[0019] 5. By introducing a compression spring, the side wall of the second limit ring can keep in contact with the side wall of the frame, thereby increasing the friction and effectively preventing the rotating ring from deflecting due to external vibration after the dynamic lens is rotated to the desired angle, further preventing unintentional changes in the angle of the dynamic lens.

[0020] 6. The meshing design of the positive ratchet and the reverse ratchet further enhances the limiting effect on the dynamic lens, which not only increases stability during normal use, but also provides an additional safety guarantee when adjusting the lens angle to prevent the lens angle from deflecting due to misoperation.

[0025] The present invention will be further described below with reference to the accompanying drawings.

[0026] Example 1

[0027] like Figure 1-2 As shown, embodiment 1 discloses a pair of dimming glasses with lenses that can be threadedly connected, comprising: a nose bridge 1, two symmetrical frames 2 welded to both ends of the nose bridge, a dimming lens unit 4, and temples 3 hinged on the outer side walls of the frames. The dimming lens unit 4 includes a connecting unit 41, a fixed lens 42 installed in the connecting unit 41, a rotating unit 43 rotatably connected to the connecting unit 41, and a dynamic lens 44 installed in the rotating unit 43. The outer wall of the connecting unit 41 is threadedly connected to the inner wall of the frame 2.

[0028] Further, such as Figure 2 As shown, the connecting unit 41 includes a connecting ring 411 whose outer wall is threadedly connected to the inner wall of the frame 2, and a first limiting ring 412 is integrally provided at the end of the connecting ring 411 away from the frame 2, and an annular boss 413 is integrally provided along the circumference of the connecting ring 411 at the angle between the outer wall of the connecting ring 411 and the first limiting ring 412, and the annular boss 413 abuts against the outer wall of the frame 2 near the end of the connecting ring 411, and the rotating unit 43 includes a rotating ring 431 whose inner wall is fitted and slidably connected to the outer wall of the limiting ring 412, and a second limiting ring 432 is integrally provided near the end of the rotating ring 431 away from the frame 2, the inner wall of the second limiting ring 432 is fitted and slidably connected to the outer wall of the annular boss 413, and the outer side wall of the second limiting ring 432 is fitted and slidably connected to the outer wall of the frame 2 near the outer side wall of the connecting ring 411, and the cross-sectional width of the second limiting ring 432 is equal to the cross-sectional width of the annular boss 413.

[0029] Further, such as Figure 2 As shown, the outer wall of the fixed lens 42 and the outer wall of the dynamic lens 44 are respectively fitted with the inner wall of the connecting ring 411 and the inner wall of the rotating ring 431. The end of the fixed lens 42 away from the dynamic lens 44 is provided with a first fixed ring 414 whose outer wall is threadedly connected to the inner wall of the connecting ring 411. The end of the dynamic lens 44 away from the fixed lens 42 is provided with a second fixed ring 433 whose outer wall is threadedly connected to the inner wall of the rotating ring 431.

[0030] Further, such as Figure 2 As shown, in order to prevent the connection between the dynamic lens and the rotating ring from loosening, which would cause the dynamic lens to be unable to rotate, two plug-in blocks 434 are symmetrically provided on the side wall of the second fixed ring 433 close to the dynamic lens 44, and two slots 441 for the plug-in blocks 434 to be inserted are symmetrically provided on the outer wall of the dynamic lens 44. When the rotating ring 431 rotates, the dynamic lens 44 is driven to rotate through the second fixed ring 433, the plug-in blocks 434 and the slots 441 in sequence.

[0031] Preferably, in order to avoid the dynamic lens from fitting against the side wall of the first limiting ring and causing wear due to rotation, a ball bearing is provided at one end of the insert block 434 close to the frame 2 (not shown in the figure), and the outer wall of the ball bearing fits against the side wall of the first limiting ring 412. The cross-sectional width of the insert block 434 is greater than the cross-sectional width of the dynamic lens 44. When the rotating ring 431 drives the second fixed ring 433 to rotate, the ball bearing rotates along the side wall of the first limiting ring 412.

[0032] Based on the above structure, Figure 1-2 As shown, during installation, first, the rotating ring 431 is sleeved with the outer wall of the first limiting ring 412, and the inner wall of the second limiting ring 432 is kept in contact with the outer wall of the annular boss 413, so that the connecting ring 411 is screwed to the frame 2, and then the fixed lens 42 is installed into the connecting ring 411, and the first fixing ring 414 is screwed into the connecting ring 411, so as to clamp and fix the fixed lens 42, and then the second fixing ring 433 is overlapped with the dynamic lens 44, and ensure that the plug 434 is inserted The second fixing ring 433 is then aligned with the end of the rotating ring 431 away from the frame 2, and the second fixing ring 433 is rotated to thread the second fixing ring 433 and the rotating ring 431. The second fixing ring 433 is threadedly connected to the rotating ring 431. When the second fixing ring 433 is threadedly connected, the dynamic lens 44 is moved toward the first limiting ring 412 until the second fixing ring 433 and the rotating ring 431 are screwed together. When adjusting the light, the dynamic lens 44 is driven by rotating the rotating ring 431.

[0033] When replacing the lens subsequently, it can be completed by releasing the threaded connection between the first fixing ring 414 and the connecting ring 411 / the second fixing ring 433 and the rotating ring 431. The replacement of the connecting ring 411 / the rotating ring 431 requires releasing the threaded connection between the connecting ring 411 and the frame 2, and releasing the connection between the rotating ring 431 and the first limiting ring 412.

[0034] Further, such as Figure 2 As shown, in order to facilitate the rotation of the first fixing ring / the second fixing ring, a snap-in groove 45 is provided on the outer wall of the first fixing ring 414 away from the dynamic lens 44 and on the outer wall of the second fixing ring 433 away from the fixed lens 42. When the first fixing ring 414 / the second fixing ring 433 needs to be rotated, the first fixing ring 414 / the second fixing ring 433 can be pushed to rotate by snapping a fingernail / a bank card / any sheet-like object with strong rigidity into the snap-in groove 45.

[0035] Further, such as Figure 3As shown, in order to facilitate the rotation of the first fixing ring / the second fixing ring, a paddle 46 is provided on the outer wall of the first fixing ring 414 away from the dynamic lens 44 and on the outer wall of the second fixing ring 433 away from the fixed lens 42. When the first fixing ring 414 / the second fixing ring 433 needs to be rotated, the first fixing ring 414 / the second fixing ring 433 can be pushed to rotate by abutting the side wall of the paddle 46 with a fingernail / a bank card / any sheet-like object with strong rigidity.

[0036] Example 2

[0037] like Figure 4 As shown, the technical feature that distinguishes the second embodiment from the first embodiment is that a compression spring 5 is sleeved on the outer wall of the annular boss 413, and the two ends of the compression spring 5 abut against the first limiting ring 412 and the opposite side of the second limiting ring 432, respectively, and the cross-sectional width of the second limiting ring 432 is less than the cross-sectional width of the annular boss 413;

[0038] Specifically, during installation, the compression spring 5 is first sleeved on the annular boss 413, and then the rotating ring 431 is sleeved on the first limiting ring 412. The setting of the compression spring 5 generates a thrust on the second limiting ring 432 in the direction of the frame 2, so that the side wall of the second limiting ring 432 always remains in contact with the side wall of the frame 2, thereby increasing the friction force, and then achieving the limitation of the rotating ring 431, thereby avoiding the dynamic lens 44 from rotating to the required angle. The vibration causes the rotating ring 431 to deflect, which causes the angle of the dynamic lens 44 to change. When adjusting the angle of the dynamic lens 44, the rotating ring 431 is pulled to the side away from the frame 2. The rotating ring 431 drives the second limiting ring 432 to release the contact with the frame 2, and the pressure spring 5 contracts. Then, the rotating ring 431 can be rotated.

[0039] Furthermore, in order to further limit the dynamic lens, the frame 2 located outside the annular boss 413 is evenly provided with positive ratchets along its circumference (not shown in the figure), and the second limiting ring 432 is evenly provided with reverse ratchets along its circumference near the outer wall of the frame 2 (not shown in the figure). The positive ratchets and the reverse ratchets are engaged with each other, and the setting of the forward ratchets and the reverse ratchets limits the second limiting ring 432, thereby limiting the dynamic lens 44.

[0040] The corresponding publication number of the frame in this utility model is CN210109488U, and the patent name is a pair of glasses body in dimming glasses.

[0041] The above are only preferred specific implementation methods of the present invention, but the protection scope of the present invention is not limited to them. Any technician familiar with the technical field can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention within the technical scope disclosed by the present invention, and they should be covered by the protection scope of the present invention.
