Description

Technical Field

[0001] This utility model relates to the field of eyeglasses, specifically to eyeglasses with lenses that are easy to install and remove. Background Technology

[0002] Full-rimmed glasses lenses are installed in slots within the frame, requiring tools to change, making it inconvenient for users to replace lenses themselves. If a separate frame, with an upper and lower frame that holds the lens in place, were used, the lens could be installed without tools. However, how to achieve quick assembly and disassembly of the upper and lower frames, as well as the temples and frame, remains a problem to be solved. Utility Model Content

[0003] In view of the shortcomings of the prior art, this utility model provides a pair of glasses with lenses that are easy to install and remove without tools, making it convenient for users to replace lenses themselves.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0005] A pair of glasses with easy lens assembly and disassembly includes a frame, a headstock, and multiple spring positioning beads. The headstock is used to hinge the temples. The frame includes an upper frame and a lower frame, which cooperate to hold the lens. The upper frame has a first protrusion extending rearward from both ends, and the first protrusion has a first mounting hole. The lower frame has a second protrusion extending from the inner side of both ends, and the second protrusion has a second mounting hole. The first mounting hole and the second mounting hole at the same end of the frame are aligned. The spring positioning beads are installed in the aligned first mounting hole and the second mounting hole.

[0006] The pile head has a limiting groove to accommodate the first protrusion and the second protrusion. The groove wall of the limiting groove is provided with a limiting hole corresponding to the ball of each spring positioning ball. The spring positioning ball and the limiting hole cooperate to realize the quick assembly and disassembly of the frame and the pile head.

[0007] In one embodiment, the spring positioning ball has only one ball, which protrudes from the first mounting hole or the second mounting hole and engages in the limiting hole of the pile head; or, the spring positioning ball has two balls, which protrude from the first mounting hole and the second mounting hole respectively and engage in the limiting hole of the pile head.

[0008] In one embodiment, the first protrusion is located above the second protrusion, the first mounting hole and the second mounting hole are vertical through holes, the top and bottom of the limiting groove of the pile head are provided with corresponding limiting holes, and the spring positioning ball has two balls, the two balls protruding upward from the first mounting hole and locking into the limiting hole at the top of the limiting groove and protruding downward from the second mounting hole and locking into the limiting hole at the bottom of the limiting groove respectively.

[0009] One of the solutions also includes a nose pad assembly, which includes a nose pad support and two nose pads connected to the nose pad support.

[0010] The upper frame has a first central bridge corresponding to the bridge of the nose of the eyeglass wearer, and the lower frame has a second central bridge corresponding to the bridge of the nose of the eyeglass wearer. The bottom surface of the first central bridge is provided with a positioning groove, and the second central bridge is partially convex to form a protrusion. The inner side of the first central bridge is provided with a first slot, and the protrusion is provided with a second slot. The protrusion is inserted into the positioning groove so that the second slot is connected to the first slot. A spring positioning bead is installed inside the first central bridge, and the lower end of the spring positioning bead extends into the first slot.

[0011] The upper end of the nose pad support has a plug-in part that can be inserted into the first slot. The plug-in part is provided with a positioning hole. When the plug-in part is inserted into the first slot and the second slot, the lower end of the spring positioning bead is automatically inserted into the positioning hole. When the nose pad assembly is subjected to an external force that causes it to disengage from the first slot and the second slot, the spring positioning bead automatically disengages from the positioning hole through elastic deformation.

[0012] In one embodiment, the inner side of the upper frame protrudes above and below the opening of the first slot to form an upper protrusion and a lower protrusion, respectively. The bottom surface of the upper protrusion is flush with the top surface of the first slot, and the top surface of the lower protrusion is flush with the bottom surface of the first slot.

[0013] This utility model has the following beneficial effects:

[0014] The two ends of the frame are quickly connected to the post via spring-loaded positioning beads. Pulling the post away from the frame separates it from the frame, allowing the upper and lower frames to be separated for lens replacement. The upper and lower frames are then reassembled to secure the lens, and the spring-loaded positioning beads are installed in the first and second mounting holes, pre-fixing the upper and lower frames. Next, the first and second protrusions are inserted into the limiting grooves of the post, and the spring-loaded positioning beads, in conjunction with the limiting holes on the post, connect the post, the upper frame, and the lower frame. Lens assembly and disassembly are tool-free and quick. Attached Figure Description

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0025] like Figures 1 to 8 As shown, this embodiment discloses a pair of eyeglasses with easily detachable lenses 5, including a frame, a headstock 6, and multiple spring positioning beads 7. The headstock 6 is used to hinge the temples 8. The frame includes an upper frame 1 and a lower frame 4, which cooperate to hold the lenses 5. The upper frame 1 has first protrusions 9 extending rearward from both ends, and the first protrusions 9 have first mounting holes. The lower frame 4 has second protrusions 11 extending from the inner sides of both ends, and the second protrusions 11 have second mounting holes. The first mounting holes and second mounting holes at the same end of the frame are aligned, and the spring positioning beads 7 are installed in the aligned first mounting holes and second mounting holes. The headstock 6 has a limiting groove 13 to accommodate the first protrusions 9 and the second protrusions 11. The groove wall of the limiting groove 13 has a limiting hole 14 corresponding to the ball of each spring positioning bead 7. The spring positioning beads 7 and the limiting holes 14 cooperate to realize the quick assembly and disassembly of the frame and the headstock 6.

[0026] The upper frame 1 and lower frame 4 are provided with grooves for mounting the lens 5. The end of the post 6 away from the frame is hinged to the temple 8. The two ends of the frame are quickly connected to the post 6 by spring positioning beads 7. Pulling the post 6 away from the frame can separate the post 6 from the frame, and then the upper frame 1 and lower frame 4 can be separated to replace the lens 5. The upper frame 1 and lower frame 4 are put back together to hold the lens 5, and the spring positioning beads 7 are installed in the first mounting hole and the second mounting hole to achieve pre-fixation of the upper frame 1 and lower frame 4. Then, the first protrusion 9 and the second protrusion 11 are inserted into the limiting groove 13 of the post 6. The spring positioning beads 7 cooperate with the limiting hole 14 on the post 6 to connect the post 6, the upper frame 1 and the lower frame 4. At this time, since the first protrusion 9 and the second protrusion 11 are both inserted into the limiting groove 13 of the post 6 and cannot be separated, the upper frame 1 and the lower frame 4 cannot be separated.

[0027] The spring positioning ball 7 is existing technology, and suitable specifications can be purchased from the market. The structure of the spring positioning ball 7 typically includes a housing with one open end, a spring and a ball disposed inside the housing, with the ball partially exposed at the open end of the housing (the diameter of the open end is smaller than the diameter of the ball to prevent the ball from falling out of the housing), one end of the spring abutting against the ball, and the other end abutting against the inner wall of the housing.

[0028] In one embodiment, the spring positioning bead 7 has only one ball, which protrudes from the first mounting hole or the second mounting hole and engages in the limiting hole 14 of the pile head 6; or, the spring positioning bead 7 has two balls, which protrude from the first mounting hole and the second mounting hole respectively and engage in the limiting hole 14 of the pile head 6.

[0029] The number of spring positioning beads 7 installed at each end of the mirror frame is unlimited; there can be one or more. When using a spring positioning bead 7 with only one ball, it is best to set two or more spring positioning beads 7 at each end of the mirror frame. At least one spring positioning bead 7 has its ball protruding from the first mounting hole and engaging in the limiting hole 14 of the post head 6 (at this time, the second mounting hole can be a through hole or a blind hole), and at least one spring positioning bead 7 has its ball protruding from the second mounting hole and engaging in the limiting hole 14 of the post head 6 (at this time, the first mounting hole can be a through hole or a blind hole).

[0030] In one embodiment, the first protrusion 9 is located above the second protrusion 11. The first and second mounting holes are vertical through holes. The top and bottom of the limiting groove 13 of the pile head 6 are provided with aligned limiting holes 14. The spring positioning ball 7 has two balls, one protruding upward from the first mounting hole and engaging with the limiting hole 14 at the top of the limiting groove 13, and the other protruding downward from the second mounting hole and engaging with the limiting hole 14 at the bottom of the limiting groove 13. In other embodiments, the first protrusion 9 and the second protrusion 11 can also be arranged to be adjacent to each other, for example, the first protrusion 9 is outside the second protrusion 11.

[0031] In one embodiment, the glasses also include a nose pad assembly, which includes a nose pad bracket 2 and two nose pads 3 connected to the nose pad bracket 2. The upper frame 1 has a first central bridge 15 corresponding to the bridge of the nose of the glasses wearer, and the lower frame 4 has a second central bridge 16 corresponding to the bridge of the nose of the glasses wearer. To make the connection between the upper frame 1 and the lower frame 4 more stable, the bottom surface of the first central bridge 15 is provided with a positioning groove 17, and the second central bridge 16 partially protrudes upward to form a protrusion 20. The inner side of the first central bridge 15 is provided with a first slot 18, and the protrusion 20 is provided with a second slot 19. The protrusion 20 is inserted into the positioning groove 17. Figure 8 This allows the second slot 19 to connect with the first slot 18. A spring positioning bead 7 is installed inside the first central beam 15, and the lower end of the spring positioning bead 7 extends into the first slot 18. The upper end of the nose pad bracket 2 has a plug-in part 21 that can be inserted into the first slot 18. The plug-in part 21 is provided with a positioning hole 22. When the plug-in part 21 is inserted into the first slot 18 and the second slot 19, the lower end of the spring positioning bead 7 automatically inserts into the positioning hole 22. When the nose pad assembly is subjected to an external force that causes it to disengage from the first slot 18 and the second slot 19, the spring positioning bead 7 automatically disengages from the positioning hole 22 through elastic deformation.

[0032] In other embodiments, the nose pad 3 and the nose pad support 2 can be integrally formed. In other embodiments, the nose pad 3 can be integrally formed into the lower frame 4, omitting the nose pad support 2.

[0033] In this embodiment, the nose pad assembly is detachably connected to the frame via a spring positioning bead 7, which facilitates the replacement of the nose pad 3. At the same time, it further ensures that the upper frame 1 and the lower frame 4 will not easily separate. The upper frame 1 and the lower frame 4 can only be separated after the nose pad 3 and the posts 6 at both ends of the frame are removed.

[0034] In one embodiment, the inner side of the upper frame 1 protrudes above and below the opening of the first slot 18, forming an upper protrusion 23 and a lower protrusion 24, respectively. The lower bottom surface of the upper protrusion 23 is flush with the top surface of the first slot 18, and the top surface of the lower protrusion 24 is flush with the bottom surface of the first slot 18. By providing the upper protrusion 23 and the lower protrusion 24, the thickness of the frame does not need to be increased. The upper protrusion 23 and the lower protrusion 24 can support the insertion part 21 of the nose pad support 2, making the nose pad assembly more stable.

[0035] The above-described embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. These modifications or substitutions do not cause the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model. Therefore, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
