Description

Technical Field

[0001] This utility model relates to the technical field of eyeglasses, and in particular to an optical eyeglass with interchangeable lenses. Background Technology

[0002] Eyeglasses typically consist of a frame, lenses mounted on the frame, and temples hinged to the sides of the frame. To secure the lenses, recesses are usually cut into the frame to hold them in place, which makes it difficult to change the lenses once they are in place. Traditional replaceable lens eyeglasses have movable structures on the frame. For example, patent number 201821145683.X discloses an eyeglasses design that allows for quick replacement of the frame, lenses, and temples. This design separates the frame into a movable upper browline and a lower browline. When changing the frame, the temples need to be disassembled and reassembled together, which presents a certain assembly difficulty. Utility Model Content

[0003] To overcome the shortcomings of the prior art, the technical solution adopted by this utility model is: an optical eyeglass with interchangeable lenses, including a frame and temples hinged to both sides of the frame. The frame has an inner groove for mounting lenses, and also includes a locking rod and an elastic body. The frame has an integrally formed upper frame and a lower bracket. The upper frame has an inverted groove and a sliding groove. The lower bracket has a hook portion adapted to the inverted groove. The sliding groove is located directly above the hook portion. The locking rod is slidably connected to the sliding groove, and the elastic body is located between the locking rod and the upper frame. The bottom of the locking rod is engaged with the hook portion.

[0004] Using the above technical solution, the frame is integrally injection molded, and then the upper frame and lower bracket are positioned in a ring shape through a heat setting process. Compared with normal glasses, the front appearance of this utility model only has inconspicuous grooves on both sides of the frame, retaining the original appearance design. Since the frame material is plastic and has a certain degree of elasticity, when it is necessary to replace the lens, push the locking rod upward to make the locking rod disengage from the lower bracket, press the lower bracket inward and make it deform slightly, disengaging the hook part from the inverted groove. At this time, the inner contour of the frame becomes larger to facilitate lens replacement. After inserting the required lens into the inner groove, push the locking rod upward, and then re-engage the hook part into the inverted groove. The locking rod moves down and locks the lower bracket. The overall replacement operation is simple and convenient, meeting the needs of users to replace lenses with different prescriptions to correct vision. It can also replace sunglasses lenses, 3D lenses and other functional lenses, with a wide range of applications.

[0005] The present invention is further configured such that the locking rod includes an integrally formed pushing part, connecting part, cylindrical part and locking part, the pushing part is connected to one side of the cylindrical part through the connecting part, and the cylindrical part and the pushing part are respectively provided on the inner and outer sides of the slide groove, and the lower bracket is provided with a locking hole adapted to the locking part.

[0006] Using the above technical solution, the locking rod has a near-I-shaped structure, and one side of its connecting groove is a cylindrical structure, which makes it move smoothly and without jamming. The moving direction of the locking part is perpendicular to the moving direction of the hook part, making the locking structure more stable, improving the structural strength of the frame, and preventing the lens from falling off due to collision.

[0007] The present invention is further configured such that the elastic body is a spring, the locking rod is provided with a connecting post coaxially distributed with the cylindrical part, one end of the spring is sleeved on the connecting post, and the other end abuts against the sliding groove.

[0008] Using the above technical solution, the spring applies a force to the locking bar towards the hook in its natural state. The limiting effect of the connecting post prevents the spring from tilting during deformation and affecting the movement of the locking bar.

[0009] The present invention is further configured such that the inverted groove is provided with a limiting part that is misaligned with the sliding groove, and the lower bracket is provided with a slot part that is adapted to the limiting part.

[0010] By adopting the above technical solution, the degree of freedom of the hook part is restricted by the limiting part, so as to prevent the upper frame and the lower bracket from being misaligned laterally.

[0011] The present invention is further configured such that the inner groove has a bottom surface and inclined surfaces connected to both sides of the bottom surface, and the inner side surface of the undercut groove is located between adjacent inclined surfaces.

[0012] By adopting the above technical solution, when replacing lenses, the connection surface between the inverted groove and the hook is located between adjacent inclined surfaces, which reduces the interference area between the inclined surfaces and the lens, making lens replacement more convenient.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. Because the frame is made of plastic and has a certain degree of elasticity, when it is necessary to change the lens, push the locking lever upward to disengage it from the lower bracket, making it easier to replace the lens. After inserting the desired lens into the inner groove, push the locking lever upward, and then re-engage the hook into the inverted slot. The locking lever will then move downward and lock the lower bracket. The overall replacement operation is simple and convenient, meeting the needs of users to change lenses of different prescriptions to correct their vision. It can also replace sunglasses lenses, 3D lenses, and other functional lenses, making it widely applicable.

[0015] 2. Compared with normal glasses, the front appearance of this utility model only has inconspicuous grooves on both sides of the frame, while retaining the original appearance design.

[0024] like Figure 1 , 2 As shown, this embodiment provides an optical eyeglass with interchangeable lenses, including a frame 1 and temples 2 hinged to both sides of the frame 1. The frame 1 has an inner groove 3 for mounting lenses, and also includes a locking rod 4 and an elastic body 5. The frame 1 has an integrally formed upper frame 6 and a lower bracket 7. The upper frame 6 has an inverted groove 8 and a sliding groove 9. The lower bracket 7 has a hook portion 10 adapted to the inverted groove 8. The sliding groove 9 is located directly above the hook portion 10. The locking rod 4 is slidably connected to the sliding groove 9, and the elastic body 5 is located between the locking rod 4 and the upper frame 6. The bottom of the locking rod 4 is engaged with the hook portion 10.

[0025] Combination Figure 3 As shown, in this embodiment, the locking rod 4 includes an integrally formed pushing part 11, connecting part 12, cylindrical part 13 and locking part 14. The pushing part 11 is connected to one side of the cylindrical part 13 through the connecting part 12, and the cylindrical part 13 and the pushing part 11 are respectively provided on the inner and outer sides of the slide groove 9. The lower bracket 7 is provided with a locking hole 16 that matches the locking part 14. The locking rod 4 has a near-I-shaped structure, and the side of it connected to the slide groove 9 is a cylindrical structure, which makes it move smoothly and without jamming. The moving direction of the locking part 14 is perpendicular to the moving direction of the hook part 10, which makes the locking structure more stable, improves the structural strength of the frame 1, and prevents the lens from falling off due to collision.

[0026] In this embodiment, the elastic body 5 is a spring, and the locking rod 4 is provided with a connecting post 15 coaxially distributed with the cylindrical part 13. One end of the spring is sleeved on the connecting post 15, and the other end abuts against the slide groove 9. In its natural state, the spring gives the locking rod 4 a force toward the hook part 10. By limiting the connection post 15, the spring is prevented from affecting the movement of the locking rod 4 due to tilting during deformation.

[0027] In this embodiment, the inverted groove 8 is provided with a limiting part 17 that is misaligned with the sliding groove 9, and the lower bracket 7 is provided with a slot part 18 that is adapted to the limiting part 17. The limiting part 17 restricts the degree of freedom of the hook part 10, preventing the upper frame 6 and the lower bracket 7 from being misaligned laterally.

[0028] Combination Figure 4-6 As shown, in this embodiment, the inner groove 3 is provided with a bottom surface 20 and inclined surfaces 21 connected to both sides of the bottom surface 20. The inner side surface 22 of the inverted groove 8 is provided between adjacent inclined surfaces 21. When replacing the lens, since the connecting surface between the inverted groove 8 and the hook part 10 is provided between adjacent inclined surfaces 21, the interference area between the inclined surface 21 and the lens is reduced, making lens replacement more convenient.

[0029] The working principle of this utility model is as follows: when it is necessary to replace the lens, push the locking rod 4 upward so that the locking rod 4 leaves the lower bracket 7, press the lower bracket 7 inward and make it deform slightly, so that the hook part 10 is disengaged from the inverted groove 8. At this time, the inner contour of the frame 1 becomes larger to facilitate the replacement of the lens. After the required lens is inserted into the inner groove 3, push the locking rod 4 upward, and then re-engage the hook part 10 into the inverted groove 8. The locking rod 4 then moves down and locks the lower bracket 7, thereby completing the replacement of the lens.

[0030] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
