Description

Technical Field

[0001] This utility model relates to the field of eyeglasses technology, specifically to a type of flip-up eyeglasses. Background Technology

[0002] Eyeglasses are essential items for people with nearsightedness or presbyopia, as they need to see objects clearly through lenses in the frame. Traditional eyeglasses have the frame and temples hinged together by a post, allowing only the temples to rotate relative to the frame.

[0003] Chinese utility model patent publication number "CN205720925U" discloses a multifunctional flip-up eyeglasses, including an eyeglass body composed of a frame and lenses. The frame includes a main frame and flip-up lenses. The main frame includes a main frame, two temples, a nose pad, and a bridge. The flip-up lenses include a flip-up frame and flip-up lenses. A raised "U"-shaped groove is provided in the upper center of the main frame. A "T"-shaped protrusion matching the "U"-shaped groove is provided in the upper center of the flip-up frame. Insertion holes are provided on the contact surfaces of the "T"-shaped protrusion and the "U"-shaped groove. The flip-up lenses are hinged to the main frame by screws passing through the insertion holes on the "T"-shaped protrusion and the "U"-shaped groove in sequence. The main frame, temples, bridge, or nose pads have concave cavities inside. Each concave cavity contains a small magnetic ball with health care function. The temples include a fixed temple and multiple movable temples.

[0004] However, the flip-up frame and main frame of the aforementioned multi-functional flip-up glasses are hinged and fixed by a "T"-shaped protrusion and a "U"-shaped slot. However, the "T"-shaped protrusion protrudes from the middle of the upper part of the flip-up frame, and the "U"-shaped slot also protrudes from the middle of the upper part of the main frame. The thickness of the "T"-shaped protrusion is inevitably left at the installation point of the flip-up frame and the main frame, which increases the overall width of the main frame and the flip-up frame. When wearing them, the upper and lower ends of the frames will contact the brow bone or cheek, resulting in low wearing comfort.

[0005] Therefore, it is necessary to improve upon the aforementioned shortcomings. Utility Model Content

[0006] The purpose of this invention is to provide a flip-up eyeglass with an overlapping frame and a smooth rotation, in order to solve the above-mentioned problems existing in the prior art.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is: a flip-up eyeglass, including a mounting frame, a flip-up frame, and temples, with the temples distributed on both sides of the mounting frame and rotating in cooperation with the mounting frame, characterized in that: the flip-up frame is hinged to the mounting frame through a hinge assembly, one end of the hinge assembly passing through the flip-up frame and the other end being fixedly connected to the end of the mounting frame near the temple.

[0008] By adopting the above technical solution: the flip-up frame and the mounting frame are overlapped, and the hinge assembly is inserted inside the flip-up frame, with the other end welded to the mounting frame. The flip-up frame flips relative to the mounting frame through the hinge assembly, and the mounting frame is located inside the glasses. When worn, the flip-up frame will not contact the face or brow bone, effectively improving the comfort of the glasses. In addition, when the user needs to raise their eyes, the flip-up frame can be rotated directly to a similar horizontal position to the mounting frame without moving the entire glasses, reducing friction between the temples and the ears, reducing discomfort caused by the sliding of the temples against the head, and significantly improving the applicability of flip-up glasses.

[0009] The aforementioned flip glasses can be further configured as follows: the hinge assembly includes a first hinge member, a second hinge member, and a first hinge bolt. The first hinge member has a fixing plate at one end and a hinge plate at the other end. The hinge plate has a first hinge hole. The second hinge member has a second hinge hole at one end and a positioning port at the other end. The second hinge member is positioned and installed on the outer surface of the mounting frame through the positioning port, and is welded and fixed at the connection between the inner wall of the positioning port and the outer surface of the mounting frame. The first hinge bolt passes through the first hinge hole and the second hinge hole to realize the rotational engagement between the first hinge member and the second hinge member.

[0010] By adopting the above technical solution: the first hinge is installed on the flip frame through a fixing plate, reducing the local stress on the first hinge; the second hinge is positioned with the frame of the mounting frame through the positioning hole and welded to the mounting frame; the first hinge bolt passes through the first hinge hole and the second hinge hole to complete the hinge fixation of the flip frame and the mounting frame, thereby effectively avoiding loosening or displacement that may occur due to frequent flipping, reducing wear and extending the service life of the glasses.

[0011] The aforementioned flip glasses can be further configured as follows: a fixing plate is provided with a fixing groove, the fixing groove divides the fixing plate to form a first fixing plate and a second fixing plate, the ends of the first fixing plate and the second fixing plate are provided with fixing hook teeth, the flip frame is provided with a mounting hole, a positioning plate that cooperates with the fixing groove is provided in the mounting hole, the mounting hole is provided with a mounting groove, and the fixing hook teeth cooperate with the mounting groove to snap the first hinge onto the flip frame.

[0012] By adopting the above technical solution, the first fixing plate and the second fixing plate are respectively inserted into the two ends of the positioning plate in the mounting hole, and the fixing hook teeth are engaged with the mounting groove. The first hinge is installed on the flip frame while the first hinge is limited, which improves the stability of the connection between the first hinge and the flip frame and enhances the durability and reliability of the glasses.

[0013] The aforementioned flip glasses can be further configured as follows: the hinge plate bends upward, the hinge pressure plate has a hinge groove in the middle, the second hinge member passes through the hinge groove, the bottom of the hinge groove has a first contact surface and a second contact surface, the first contact surface and the second contact surface are set at an angle, the first contact surface and the second contact surface can contact the side wall of the second hinge member, and limit the rotation angle of the second hinge member relative to the first hinge member.

[0014] By adopting the above technical solution, the hinge plate bends upward, increasing the rotation angle of the second hinge member within the hinge groove, allowing the flip frame to rotate at a greater angle relative to the mounting frame. The first and second contact surfaces, which are inclined at the bottom of the hinge groove, can limit the second hinge member when it rotates to its limit angle, preventing the flip frame from rotating excessively and avoiding component wear or structural damage caused by excessive rotation, thereby improving the reliability and durability of the eyeglasses.

[0015] The aforementioned flip glasses can be further configured as follows: the mounting frame includes a first frame, a second frame, and a connecting beam. The first frame and the second frame are semi-frame shaped. The first frame has a first nose pad at its end, and the second frame has a second nose pad at its end. The first frame and the second frame are fixedly connected by the connecting beam. The first frame has a first connecting plate near the temple, and the second frame has a second connecting plate near the temple. Both the first connecting plate and the second connecting plate have positioning grooves. The positioning opening of the second connecting piece cooperates with the positioning groove.

[0016] By adopting the above technical solution: the semi-frame-shaped first and second frames prevent the installed frames from contacting the face when worn, and the first and second frames are bent downwards on one side. The first nose pad is set on the first frame and the second nose pad is set on the second frame. The first and second nose pads can be stably mounted on the bridge of the nose, improving the stability of wearing glasses. In addition, the positioning grooves opened on the first and second connecting plates are matched with the positioning port of the second connector, so that the second hinge can be stably welded to the installed frames. This ensures the alignment accuracy of the flip frame during rotation and the rigidity of the overall structure, effectively improving the assembly quality and long-term stability of the product.

[0017] The aforementioned flip glasses can be further configured such that: a connecting groove is provided at the end of the temple, a connector is provided in the connecting groove, a connecting post is provided on the mounting frame, and the connecting post and the connector are hinged together by a second hinge bolt.

[0018] By adopting the above technical solution: the connector is inserted into the connecting groove and fixedly connected to the temple, the connecting post is welded to the mounting frame, and the temple and the mounting frame can be connected by hinged by the second hinge bolt. The temple can rotate around the second hinge bolt through the connector to realize the opening and closing of the temple.

[0019] The aforementioned flip glasses can be further configured as follows: the connector includes a mounting plate and a hinge plate, the hinge plate has a third hinge hole, the connecting pile head has a rotating groove, the hinge plate passes through the rotating groove, the connecting pile head has a fourth hinge hole connected to the rotating groove, a second hinge bolt passes through the third hinge hole and the fourth hinge hole, the mounting plate has several sets of first fixing holes, the connecting groove has a second fixing hole corresponding to the first fixing hole, and a fixing bolt passes through the first fixing hole and the second fixing hole.

[0020] By adopting the above technical solution: the connector inserts the hinge plate into the rotating groove of the connecting pile head, and aligns the third hinge hole on the hinge plate with the fourth hinge hole on the connecting pile head. Then, the second hinge bolt passes through the third and fourth hinge holes, realizing the rotational engagement between the connector and the connecting pile head, making installation and maintenance more convenient. In addition, the connector is set with the first fixing hole on the mounting plate and the second fixing hole in the connecting groove corresponding to each other. Then, the fixing bolt is inserted into the first and second fixing holes to fix the connector to the temple, effectively avoiding stress concentration and improving the reliability of long-term use.

[0021] The aforementioned flip glasses can be further configured such that: the rotating groove is provided with a first positioning surface and a second positioning surface, the first positioning surface and the second positioning surface are inclined, and the first positioning surface and the second positioning surface can abut against the hinge plate.

[0022] By adopting the above technical solution: the connection between the first and second positioning surfaces at the bottom of the rotating groove of the connecting pin is at an obtuse angle. When the hinge plate of the connector rotates to its limit angle within the rotating groove, it forms an angle limiting structure with the hinge plate. When the temples are unfolded or folded, the hinge plate will abut against the first or second positioning surface, thereby limiting the rotation range of the temples. This ensures that the temples can be stably positioned in the working position when worn, and can fit tightly when folded, improving the user experience and portability of the glasses.

[0023] The beneficial effects of this utility model are as follows: the flip frame and the mounting frame are overlapped and hinged together by a hinge assembly. Compared with the traditional top and bottom hinge method, the overlapping flip frame will not come into contact with the brow bone or face when worn. Furthermore, the first hinge is inserted into the flip frame through a fixed plate and is hinged to the second hinge through the hinge plate, so that the flip frame can rotate relative to the mounting frame. When wearing the glasses, the glasses can be directly rotated and flipped, which significantly improves the comfort of wearing glasses.

[0024] Furthermore, the positioning port of the second hinge is positioned with the positioning groove of the first frame and the second frame of the mounting frame. Then, the second hinge is welded into the positioning groove to achieve the connection and fixation between the second hinge and the mounting frame. The first hinge and the second hinge have high firmness, and the rotation of the flipped frame is more stable.

Detailed Implementation

[0027] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0028] like Figures 1 to 10 As shown, a type of flip-up glasses includes a mounting frame 1, a flip-up frame 2, and temples 3. The temples 3 are distributed on both sides of the mounting frame 1 and rotate with it. The flip-up frame 2 is hinged to the mounting frame 1 via a hinge assembly 4. One end of the hinge assembly 4 passes through the flip-up frame 2, and the other end is fixedly connected to the end of the mounting frame 1 near the temple 3. The flip-up frame 2 and the mounting frame 1 overlap, with the hinge assembly 4 passing through the flip-up frame 2 and the other end welded to the mounting frame 1. The flip-up frame 2 flips relative to the mounting frame 1 via the hinge assembly 4, and the mounting frame 1 is located inside the glasses. When worn, the flip-up frame 2 does not contact the face or brow bone, effectively improving the comfort of the glasses. Furthermore, when the user needs to raise their eyes, the flip-up frame 2 can be directly rotated to a similar horizontal position to the mounting frame 1 without moving the entire pair of glasses, reducing friction of the temples 3 against the ears and minimizing discomfort caused by the sliding of the temples 3 against the head, significantly improving the applicability of the flip-up glasses.

[0029] like Figures 1 to 4 As shown, the mounting frame 1 includes a first frame 11, a second frame 12, and a connecting beam 13. The first frame 11 and the second frame 12 are semi-frame-shaped. The first frame 11 is provided with a first nose pad 14 at its end, and the second frame 12 is provided with a second nose pad 15 at its end. The first frame 11 and the second frame 12 are fixedly connected by the connecting beam 13. The first frame 11 is provided with a first connecting plate 16 near the temple 3, and the second frame 12 is provided with a second connecting plate 17 near the temple 3. Both the first connecting plate 16 and the second connecting plate 17 are provided with positioning grooves 18. The positioning port 422 of the second hinge 42 cooperates with the positioning groove 18. The semi-frame-shaped first frame 11 and second frame 12 prevent the mounted eyeglass frame 1 from contacting the face when worn. The first frame 11 and the second frame 12 are bent downwards on one side. The first nose pad 14 is set on the first frame 11 and the second nose pad 15 is set on the second frame 12. The first nose pad 14 and the second nose pad 15 can be stably mounted on the bridge of the nose, improving the stability of wearing the glasses. In addition, the positioning grooves 18 opened on the first connecting plate 16 and the second connecting plate 17 are positioned and cooperate with the positioning port 422 of the second hinge 42, so that the second hinge 42 can be stably welded to the mounted eyeglass frame 1. This ensures the alignment accuracy and overall structural rigidity of the flip-up eyeglass frame 2 during rotation, effectively improving the assembly quality and long-term stability of the product.

[0030] like Figure 5 As shown, a connecting groove 31 is provided at the end of the temple 3, and a connector 32 is provided in the connecting groove 31. A connecting post 33 is provided on the mounting frame 1. The connecting post 33 and the connector 32 are hinged together by a second hinge bolt 34. The connector 32 passes into the connecting groove 31 and is fixedly connected to the temple 3. The connecting post 33 is welded to the mounting frame 1. The temple 3 and the mounting frame 1 are connected by hinged connection of the connector 32 and the connecting post 33 through the second hinge bolt 34. The temple 3 can rotate around the second hinge bolt 34 through the connector 32, realizing the opening and closing of the temple 3.

[0031] like Figures 6 to 9 As shown, the connector 32 includes a mounting plate 321 and a hinge plate 322. The hinge plate 322 has a third hinge hole 323. The connecting pile head 33 has a rotating groove 331. The hinge plate 322 passes through the rotating groove 331. The connecting pile head 33 has a fourth hinge hole 332 connected to the rotating groove 331. The second hinge bolt 34 passes through the third hinge hole 323 and the fourth hinge hole 332. The mounting plate 321 has several sets of first fixing holes 324. The connecting groove 31 has second fixing holes 311 corresponding to the first fixing holes 324. Fixing bolts 312 pass through the first fixing holes 324 and the second fixing holes 311. The connector 32 inserts the hinge plate 322 into the rotating groove 331 of the connecting pile head 33, and aligns the third hinge hole 323 on the hinge plate 322 with the fourth hinge hole 332 on the connecting pile head 33. Then, the second hinge bolt 34 passes through the third hinge hole 323 and the fourth hinge hole 332, realizing the rotational engagement between the connector 32 and the connecting pile head 33, making installation and maintenance more convenient. In addition, the connector 32 is correspondingly set through the first fixing hole 324 on the mounting plate 321 and the second fixing hole 311 in the connecting groove 31. Then, the fixing bolt 312 is inserted into the first fixing hole 324 and the second fixing hole 311 to fix the connector 32 to the temple 3, effectively avoiding stress concentration and improving the reliability of long-term use.

[0032] The rotating groove 331 is provided with a first positioning surface 333 and a second positioning surface 334. The first positioning surface 333 and the second positioning surface 334 are inclined and can abut against the hinge plate 322. The connection between the first positioning surface 333 and the second positioning surface 334 at the bottom of the rotating groove 331 connecting the pin 33 is at an obtuse angle. When the hinge plate 322 of the connector 32 rotates to its limit angle within the rotating groove 331, it forms an angle limiting structure with the hinge plate 322. When the temple 3 is unfolded or folded, the hinge plate 322 will abut against the first positioning surface 333 or the second positioning surface 334, thereby limiting the rotation range of the temple 3. This ensures that the temple 3 can be stably in the working position when worn, and can fit tightly when folded, improving the user experience and portability of the glasses.

[0033] like Figure 1 , Figure 2 , Figures 10 to 12 As shown, the hinge assembly 4 includes a first hinge member 41, a second hinge member 42, and a first hinge bolt 43. The first hinge member 41 has a fixing plate 411 at one end and a hinge plate 412 at the other end. The hinge plate 412 has a first hinge hole 413. The second hinge member 42 has a second hinge hole 421 at one end and a positioning port 422 at the other end. The second hinge member 42 is positioned and installed on the outer surface of the mounting frame 1 through the positioning port 422, and is welded and fixed at the connection between the inner wall of the positioning port 422 and the outer surface of the mounting frame 1. The first hinge bolt 43 passes through the first hinge hole 413 and the second hinge hole 421 to realize the rotational engagement between the first hinge member 41 and the second hinge member 42. The first hinge 41 is mounted on the flip frame 2 through the fixing plate 411, reducing the local stress on the first hinge 41. The second hinge 42 is positioned with the frame of the mounting frame 1 through the positioning hole 422 and welded to the mounting frame 1. The first hinge bolt 43 passes through the first hinge hole 413 and the second hinge hole 421 to complete the hinge fixation of the flip frame 2 and the mounting frame 1, thereby effectively avoiding loosening or displacement that may occur due to frequent flipping, reducing wear and extending the service life of the glasses.

[0034] The fixing plate 411 has a fixing groove 414, which divides the fixing plate 411 to form a first fixing plate 4111 and a second fixing plate 4112. The ends of the first fixing plate 4111 and the second fixing plate 4112 are provided with fixing hook teeth 4113. The flip frame 2 has a positioning hole 21, and a positioning plate 22 that mates with the fixing groove 414 is provided in the positioning hole 21. The positioning hole 21 has an installation groove 23. The fixing hook teeth 4113 mate with the installation groove 23 to snap the first hinge 41 onto the flip frame 2. The first fixing plate 4111 and the second fixing plate 4112 are respectively inserted into the two ends of the positioning plate 22 in the positioning hole 21, and the fixing hook teeth 4113 are snapped into the installation groove 23. This installs the first hinge 41 onto the flip frame 2 and limits the position of the first hinge 41, improving the stability of the connection between the first hinge 41 and the flip frame 2, and enhancing the durability and reliability of the glasses.

[0035] The hinge plate 412 is bent upwards, and a hinge groove 4121 is provided in the middle of the hinge plate 412. The second hinge member 42 passes through the hinge groove 4121. The bottom of the hinge groove 4121 is provided with a first contact surface 4122 and a second contact surface 4123. The first contact surface 4122 and the second contact surface 4123 are set at an angle. The first contact surface 4122 and the second contact surface 4123 can contact the side wall of the second hinge member 42, thereby limiting the rotation angle of the second hinge member 42 relative to the first hinge member 41. The hinge plate 412 bends upward, increasing the rotation angle of the second hinge member 42 within the hinge groove 4121. This allows the flip frame 2 to rotate at a greater angle relative to the mounted frame 1. The first contact surface 4122 and the second contact surface 4123, which are inclined at the bottom of the hinge groove 4121, can limit the second hinge member 42 when it rotates to its limit angle, preventing the flip frame 2 from rotating excessively. This avoids wear or structural damage to components caused by excessive rotation, thereby improving the reliability and durability of the eyeglasses.

[0036] The working principle of this embodiment is as follows: The fixing plate 411 of the first hinge 41 is inserted into the positioning hole 21 on the flip mirror frame 2 and the positioning plate 22 is inserted into the fixing groove 414. At the same time, the fixing hook 4113 cooperates with the mounting groove 23 to install the first hinge 41 on the flip mirror frame 2. The second hinge 42 abuts the inner wall of the positioning port 422 with the outer surface of the connecting groove 31 of the mounting mirror frame 1, and then is fixed to the mounting mirror frame 1 by welding.

[0037] Subsequently, the second hinge member 42 is inserted into the hinge groove 4121 of the hinge plate 412, and after the first hinge hole 413 and the second hinge hole 421 are aligned, the first hinge bolt 43 is inserted to rotate and engage the flip frame 2 and the mounting frame 1.

[0038] Then, the mounting plate 321 of the connector 32 is inserted into the connecting groove 31, and the fixing bolt 312 passes through the first fixing hole 324 and the second fixing hole 311 to fix the connector 32 to the temple 3. Then, the temple 3 is moved, and the hinge plate 322 is inserted into the rotating groove 331 in the middle of the connecting post 33 on the mounting frame 1. The third hinge hole 323 and the fourth hinge hole 332 are aligned, and then the second hinge bolt 34 is inserted to hinge the temple 3 to the mounting frame 1.

[0039] When in use, first rotate the temple 3 outwards. The temple 3 drives the connector 32 to rotate around the second hinge bolt 34. When the hinge plate 322 abuts against the second positioning surface 334 in the rotating groove 331, the temple 3 is fully opened. Then, place the temple 3 on the ear, and the first nose pad 14 and the second nose pad 15 rest against the user's nose bridge to complete the wearing of the glasses. When it is necessary to flip the lenses, hold the flip frame 2 and rotate it outwards to drive the flip frame 2 to rotate around the first hinge bolt 43 to achieve the flipping of the lenses. Moreover, the upper end of the flip frame 2 will not contact the user's brow bone, which improves the user's wearing comfort.

[0040] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
