Technical Field

[0001] This utility model relates to the field of eyeglasses technology, specifically to eyeglasses with detachable lenses and a stable structure. Background Technology

[0002] Eyeglasses are essential for improving vision and protecting eyesight, especially for people with myopia. As the number of people with myopia increases year by year, their needs for eyeglasses have become more diverse, no longer solely focusing on functionality but also increasingly emphasizing other benefits. However, existing eyeglasses, once manufactured, cannot have their style or color changed, failing to meet certain personalized needs.

[0003] Currently, nearsighted people usually choose frames that look good and are comfortable to wear, as well as lenses that are appropriate for their nearsightedness when getting glasses. However, once the lenses and frames are installed, they are not easy to remove later. In use, the lenses are often easily damaged, and if the lenses need to be replaced, they need to go to an optical shop or a specialized repair shop, which is quite troublesome.

[0004] In response to the above problems, the applicant applied for and disclosed a pair of glasses that are easy to replace lenses in 2023, with the publication number CN220584498U. The glasses disclosed in this technical solution are convenient for nearsighted people to replace lenses and are easy to operate. However, since there is only one connection point between the glasses frame and the connector in this technical solution, and it is fixed by screws, the stability after connection is poor, and the lens holder is prone to loosening or even breaking during use. Utility Model Content

[0005] Therefore, in order to overcome the above-mentioned shortcomings, this utility model provides a pair of glasses with detachable lenses and a stable structure. The glasses not only facilitate the movable connection between the frame and the lens holder through the first connecting part and the second connecting part, so as to realize the replacement of the lens, but also add a stepped bonding surface that plays a stabilizing role on the basis of lens replacement.

[0040] The technical solution of this utility model will be further described in detail below through specific embodiments and in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only for illustration and explanation of this utility model and are not intended to limit this utility model in any way. The accompanying drawings in this utility model are only for illustrative purposes and to facilitate understanding of the embodiments and are not intended to limit this utility model in any way.

[0041] It should be noted that the structures, proportions, sizes, etc. shown in the accompanying drawings are only for the purpose of assisting those skilled in the art in understanding and reading the content disclosed in the specification, and are not intended to limit the conditions under which the present invention can be implemented. Any modifications to the structure, changes in the proportions, or adjustments to the size, without affecting the effects and purposes that the present invention can produce, should still fall within the scope of the technical content disclosed in the present invention.

[0042] As described in the background section, existing eyeglasses typically require professional personnel to disassemble and replace the lenses and frames, making it inconvenient for nearsighted individuals to replace them themselves and compromising the ease of use. While some eyeglasses allow for lens removal, the lenses are not very stable during installation, and screws can easily loosen or even fall off during use.

[0043] Based on the above reasons, and in order to overcome the aforementioned shortcomings, this utility model provides the following technical solution to address the problems.

[0044] Example 1:

[0045] A pair of eyeglasses with detachable lenses and a stable structure includes a frame 1 having a first connecting part 4;

[0046] Lens holder 2 has a second connecting part 5;

[0047] The lens holder 2 and the frame 1 are movably connected through the first connecting part 4 and the second connecting part 5, and a stepped mating surface that provides stability is formed between the lens holder 2 and the frame 1.

[0048] The first connecting part 4 is provided in the direction of the eyes looking towards the frame 1 after the glasses are put on. The lens holder 2 is connected to the frame 1 through the combination of the second connecting part 5 and the first connecting part 4.

[0049] The stepped bonding surface is located at the bottom of the eyeglass frame 1.

[0050] The frame 1 has a receiving hole 8 for holding spare eyeglass screws. Preferably, the receiving hole is a threaded hole, and preferably, the receiving hole is located on both sides of the frame or at the corners of both sides of the frame.

[0051] The connection methods of the first connecting part 4 and the second connecting part 5 include insertion connection, bottom insertion connection, hanging connection, groove connection, spring-loaded connection, spring sheet connection, corrugated sheet connection, or single-piece connection.

[0052] In one embodiment, two first connecting portions with a center-to-center distance of 50-75 mm are provided on the frame.

[0053] A second connecting part is provided on the lens holder, and the second connecting part is connected to the first connecting part by snap-fit.

[0054] Optionally, the snap-fit ​​connection is wherein the second connecting part is inserted into the first connecting part from the first direction, wherein the insertion depth is 2~6mm; the first direction is the direction in which the eyes look towards the frame after the glasses are put on.

[0055] Optionally, the first connecting part is a fixing groove provided on the frame, which is a blind hole or a through hole.

[0056] In another embodiment, the frame has two first connecting portions with a center distance of 50-75mm.

[0057] A second connecting part is provided on the lens holder, and the second connecting part is connected to the first connecting part by snap-fit.

[0058] The snap-fit ​​design makes lens bracket installation and removal more convenient and quick. The center distance between the two first connecting parts is set to 50-75mm, thus determining the spacing between the connection points of the two lens brackets. Once the lens bracket size is fixed, the spacing between the two lenses is also fixed. This spacing can be used in conjunction with the lens bracket spacing in the applicant's four patents (CN 220626798 U, CN220543215U, CN220584498U, and CN220569031 U). The above four patents and the glasses described in this application can be sold as a set (because the above four patent solutions and the solution described in this application share a set of lens brackets). After users adapt to the spacing of ordinary eyeglass lenses, wearing eyewear using the above patents will be more comfortable. Two first connecting parts are provided on the frame because of the variety of eyeglass styles; the bridge of the glasses may have a small curve, a large curve, or be straight, etc. If there were multiple first connecting parts, matching would be difficult, and the compatibility with connecting devices would be low.

[0059] To enable quick installation and removal of the lens holder, the snap-fit ​​connection involves the second connecting part being inserted into the first connecting part from a first direction, with an insertion depth of 2-6 mm; the first direction is the direction in which the eyes look towards the frame after wearing the glasses. Optionally, the first connecting part is located in the direction in which the eyes look towards the frame after wearing the glasses, and this first connecting part is a fixing groove on the frame, which can be a blind hole or a through hole.

[0060] Because the length of the lens holder is 30-60mm and the frame length is around 140mm, insufficient insertion depth leads to insufficient contact surface at the connection point, resulting in inadequate support and causing the lens holder to wobble. This can easily lead to deformation during vigorous movement. Furthermore, in special cases, after the second connecting part is inserted into the first connecting part, a longitudinal fastening screw is added for tightening. The diameter of commonly used eyeglass fastening screws is 1.2-1.6mm. Therefore, to better provide support for the lens holder and facilitate the installation of the fastening screw, the second connecting part is inserted into the first connecting part to a depth of 2-6mm. The second connecting part and the first connecting part use a clearance fit to control the tightness of the insertion.

[0061] Example 2:

[0062] Please see the appendix Figure 1 Appendix Figure 2 and attached Figure 6 This embodiment is a further refinement of the stepped bonding surface in embodiment 1. Specifically, the stepped bonding surface is a stepped platform 3 provided on the contact surface between the lens holder 2 and the frame 1. When the first connecting part 4 and the second connecting part 5 are connected, the lens holder 2 contacts the side and bottom of the frame 1 through the stepped platform 3.

[0063] Example 3:

[0064] Please see the appendix Figure 5 This embodiment is another form of the stepped bonding surface in embodiment 2. Specifically, the stepped bonding surface is a limiting bracket 7 provided on the lens holder 2. When the first connecting part 4 and the second connecting part 5 are connected, the lens holder 2 and the frame 1 are bonded together and the limiting bracket 7 is kept in contact with the bottom of the frame 1.

[0066] Please see the appendix Figure 7 and attached Figure 8 This embodiment is another form of connection between the frame and the lens holder in embodiment 3. Specifically, the stepped contact surface is a limiting bracket 7 set on the lens holder 2. When the first connecting part 4 and the second connecting part 5 are connected, the lens holder 2 and the frame 1 are attached together and the limiting bracket 7 is in contact with the bottom of the frame 1.

[0067] The difference between Embodiment 3 and Embodiment 4 is that in Embodiment 3, the lens holder 2 is inserted into and fixed to the frame 1 from the rear end (i.e. the end closest to the human face), while in Embodiment 4, the lens holder 2 is inserted into and fixed to the frame 1 from the front end.

[0068] Example 5:

[0069] Please see the appendix Figure 3 and attached Figure 4 This embodiment is another form of the stepped bonding surface in embodiment 2. Specifically, the stepped bonding surface is a step 3 set on the lens holder 2 and a limiting block 6 set on the frame 1 that matches the step 3. The step 3 and the limiting block 6 are respectively set on the opposing surfaces of the lens holder 2 and the frame 1. When the first connecting part 4 and the second connecting part 5 are connected, the lens holder 2 is fixed to the frame 1 by the combination of the step 3 and the limiting block 6.

After the groove of the fourth insertion block 504 engages with the protrusion of the fourth support block 404, it is fixed by fasteners to form a groove-type connection between the first connecting part 4 and the second connecting part 5.

[0082] Example 10:

[0083] Please see the appendix Figure 13 This embodiment is a further supplement to the first connecting part 4 and the second connecting part 5 in embodiment 1, which are spring-loaded connections, as follows:

[0084] The first connecting part 4 is a fifth support block 405 disposed on the frame 1, and the second connecting part 5 is a fifth insertion block 505 disposed on the top of the lens holder 2. The fifth support block 405 specifically includes...

[0085] Support housing 4051, with an opening at the top forming a cavity;

[0086] The support cover 4052 covers the top opening of the support housing 4051;

[0087] An insertion hole 4053 is formed on the opposing surfaces of the support housing 4051 and the fifth insertion block 505 and communicates with the cavity inside the support housing 4051.

[0088] Limiting blocks 4054 are distributed in the cavity of the support housing 4051 on both sides of the insertion hole 4053;

[0089] The top head 4056 is connected at one end to the inner wall of the cavity of the support housing 4051 via a spring plate 4055, and at the other end moves in a straight line through the limiting block 4054. The moving direction of the top head 4056 is perpendicular to the insertion direction of the fifth support block 405 and the fifth insertion block 505.

[0090] The fifth insertion block 505 is sized to match the insertion hole 4053. An arc-shaped groove 5051 is provided on the side of the fifth insertion block 505. When the fifth insertion block 505 is inserted into the insertion hole 4053 of the fifth support block 405, the end of the fifth insertion block 505 pushes the top head 4056 to compress the spring plate 4055 and move it towards the inner wall of the support housing 5041 until the arc-shaped groove 5051 on the side of the fifth insertion block 505 corresponds to the position of the top head 4056. Through the elasticity of the spring plate 4055, the top head 4056 is pushed into the arc-shaped groove 5051 to realize the connection between the fifth insertion block 505 and the fifth support block 405, forming a spring-loaded connection between the first connecting part 4 and the second connecting part 5.

[0091] Example 11:

[0092] Please see the appendix Figure 14 This embodiment is a further supplement to the first connecting part 4 and the second connecting part 5 in embodiment 1, which are connected by a spring sheet, as follows:

[0093] The first connecting part 4 is a sixth support block 406 disposed on the frame 1, and the second connecting part 5 is a sixth insertion block 506 disposed on the top of the lens holder 2. The sixth support block 406 has an insertion groove 4061 on its corresponding surface to the lens holder 2. A limiting groove 4062 communicating with the insertion groove 4061 is provided on the top of the sixth support block 506. An elastic pad 5061 is disposed on the top of the sixth insertion block 506, one end of which is hinged to the side of the top of the sixth insertion block 506 near the frame 1. The other end of 5061 is inclined upward and elastically connected to the top of the sixth insertion block 506. When the sixth insertion block 506 is inserted into the insertion groove 4061 of the sixth support block 406, the elastic pad 5061 is squeezed and rotated downward until the elastic pad 5061 is in the limiting groove 4062. At this point, the elastic pad 5061 loses the limiting position at the top of the insertion groove 4061 and rotates upward under the action of elastic force to insert into the limiting groove 4062, thereby connecting the sixth support block 406 and the sixth insertion block 506 and forming a spring-plate type connection between the first connecting part 4 and the second connecting part 5.
