Description

Technical Field

[0001] This utility model relates to the field of spectacle lens installation technology, specifically to a yellowing-resistant PC spectacle lens. Background Technology

[0002] PC lenses are resistant to yellowing, which extends their service life and maintains the stability of the lenses during use. However, when existing resistant lenses are used with eyeglass frames, they cannot effectively keep the glasses in place on the user's face. Vigorous movement by the user can easily cause the glasses to fall and break.

[0003] According to patent document CN219715783U, a photochromic lens resistant to yellowing is disclosed, comprising a photochromic lens body and a mounting frame. The photochromic lens body is mounted within the mounting frame. The photochromic lens body includes a lens layer, a first reinforcing layer fixedly disposed on the inner side of the lens layer, a first protective layer fixedly disposed on the side of the first reinforcing layer away from the lens layer, a photochromic layer fixedly disposed on the side of the first protective layer away from the first reinforcing layer, and a second protective layer fixedly disposed on the side of the photochromic layer away from the first protective layer. A second reinforcing layer is fixedly installed on one side. This technical solution, in use, utilizes a structure consisting of a first reinforcing layer, a first protective layer, a second reinforcing layer, and a second protective layer. The protective layer increases the surface hardness of the lens and prevents scratches. The reinforcing layer further enhances the surface hardness of the photochromic lens, improving its scratch resistance. This solves the problem of low hardness in a thin photochromic layer with a high concentration of photochromic compounds, which offers the advantage of rapid color change. While this solution enhances the lens's hardness, it cannot effectively fix the lens to the eyeglass frame or adjust the spacing between lenses, causing inconvenience during use.

[0004] Therefore, a yellowing-resistant PC eyeglass lens is proposed to solve the problems mentioned above. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a yellowing-resistant PC spectacle lens, including a temple.

[0013] Compared with the prior art, this utility model provides a PC eyeglass lens that is resistant to yellowing, and has the following beneficial effects: 1. This utility model uses a support component to support the lenses. While the support component provides support, the threaded column and threaded tube work together to adjust the width between the support frame and the movable frame. By changing the width of the movable frame and the support frame, the spacing between the lenses can be adjusted, thereby achieving a micro-adjustment of the eye's focal point.

[0014] 2. In this utility model, the lens is installed on a fixed column and a fixed frame with screws. The fixed frame and fixed column work together to provide three-point fixed support for the lens. The lens is fixed with screws to prevent it from falling off after falling to the ground.

[0015] 3. In this utility model, after the fixing bolt is removed, the movable rod loses its limit position. After the movable rod is rotated out by the rotating column, the internal elastic rope is exposed. The movable rod and the support leg are installed at the top and bottom of the ear. The elastic rope is wrapped around the back of the ear and completes the fixed support of the support leg. After the movable rod is installed inside the storage slot, the locking ball and the locking hole cooperate to achieve a temporary limit position. When the fixing bolt is fixed, the movable rod is stably fixed. It can be used according to different situations. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example: Please see Figure 1 - Figure 7In this embodiment, a yellowing-resistant PC eyeglass lens includes a support 1, a limit rod 2 fixed to one end of the support 1, a fixed frame 3 movably mounted on the other end of the support 1, a lens 4 fixedly mounted on the fixed frame 3, a support assembly 5 fixedly mounted between the lenses 4, the support assembly 5 including a support frame 19, a bracket 20 welded on the support frame 19, movable frames 21 movably mounted at both ends of the support frame 19, a support column 22 welded to one side of the movable frame 21, a support hole 26 opened on one side of the lens 4, and one end of the support column 22 movably mounted inside the support hole 26; Among them, the support column 22 is installed in the support hole 26 from four positions to provide multi-point internal support for the lens 4, effectively realizing the stability between the lenses 4. Before installation, the movable frame 21 rotates between the movable frames 21. After the movable frames 21 rotate, the width between them is adjusted. After the width between the movable frames 21 is adjusted, the distance between the lenses 4 can be adjusted, so as to adjust according to the different distances between each person's glasses. The adjustment of the position of the lens 4 can also realize the adjustment of the focal point position. Please see Figure 4 - Figure 6 The support frame 19 has connecting columns 23 welded to both ends, and threaded columns 25 are fixed on the connecting columns 23. A threaded tube is fixed inside the movable frame 21. One end of the threaded column 25 is rotatably installed inside the threaded tube. The fixed frame 3 has a mounting hole 16. A limit bolt 24 is rotatably installed at the bottom of the movable frame 21. One end of the limit bolt 24 is movably in contact with one side of the threaded column 25. A nose pad is fixedly installed on the bracket 20. Among them, after the limit bolt 24 rotates, it presses against one end of the threaded column 25. The pressing force of the limit bolt 24 prevents the threaded column 25 from rotating inside the threaded tube later, thereby ensuring the stability between the movable frame 21 and the support frame 19. Furthermore, when briefly storing the elastic cord 11, the elastic cord 11 can be installed inside the fixing groove 10 and the storage groove 7. After the fixing rod 8 is installed inside the storage groove 7, the locking bead 14 is pushed by the support mechanism 15 to enter the locking hole 13 to temporarily limit and fix the movable rod, which facilitates the reciprocating and quick folding and storage of the movable rod 8 later. Please see Figure 2 - Figure 4 A fixing post 18 is welded onto the fixing frame 3. Both the fixing post 18 and the fixing frame 3 have openings 17. The other side of the lens 4 has a fixing hole 27 and a connecting hole 28. The connecting hole 28 and the opening 17 are aligned. A screw is rotatably installed inside the connecting hole 28. One end of the screw is rotatably installed inside the opening 17. The bottom of the support leg 1 has a storage groove 7. A movable rod 8 is movably installed inside the storage groove 7. One end of the movable rod 8 is fixed with a rotating post 9. One end of the rotating post 9 is rotatably installed inside the storage groove 7. The screw is installed in both the fixing hole 27 and the opening 17 through the connecting hole 28 on the side of the lens 4. The screw is installed on the fixing post 18. The fixing post 18 and the screw work together to provide multi-point support for the lens 4. The screw also fixes the fixing post 18 in the opening 17. After the screw is removed, the lens 4 can be quickly removed from the mounting bracket 3. Lens 4 itself is made of a yellowing-resistant material, which ensures stable use and extends service life. Please see Figure 1 - Figure 3 The movable rod 8 has a fixing groove 10 inside, and an elastic rope 11 is movably installed inside the fixing groove 10. One end of the elastic rope 11 has a through hole 12, and a bolt is fixed inside the through hole 12. A fixing bolt 6 is rotatably installed on one side of the support leg 1, and a limit component is fixedly installed on the other side of the support leg 1. The limit component includes a groove, and a support mechanism 15 is fixed inside the groove. A locking hole 13 is opened on one side of the movable rod 8. A locking bead 14 is fixed at one end of the support mechanism 15 and is movably installed inside the locking hole 13. Among them, the support mechanism 15 is a support spring. After the support spring is compressed, it generates a rebound force. When the movable rod 8 needs to be fixed for a long time, the fixing bolt 6 is rotated to squeeze and fix one side of the movable rod 8. When the movable rod 8 needs to be taken out for use later, the fixing bolt 6 is rotated to loosen and lose the squeezing of the movable rod 8. Under external force, the movable rod 8 rotates through the rotating column 9. After the rotating column 9 rotates, one end of the movable rod 8 drives the elastic rope 11 to be taken out from the inside of the storage groove 7 and the fixing groove 10. In later use, if the elastic cord 11 breaks or is damaged, the bolt can be removed from the inside of the through hole 12, and the elastic cord 11 can be removed from the inside of the fixing groove 10 and the storage groove 7. After removal, a new elastic cord 11 can be used. After the movable rod 8 is opened, the elastic cord 11 is wrapped around the side of the ear. The limiting and fixing of the elastic cord 11 effectively prevents the glasses from falling off and causing damage during vigorous exercise. Later, the elastic cord 11 can be stored inside the fixing groove 10 and the storage groove 7 to avoid the impact caused by the elastic cord 11 being exposed.

[0020] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. As long as they can achieve their beneficial effects, they can be implemented. Therefore, this embodiment will not elaborate on their specific structural composition and working principle.

[0021] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
