Description

Technical Field

[0001] This utility model relates to the field of eyeglasses technology, specifically to an eyeglass frame that facilitates lens replacement. Background Technology

[0002] In the eyeglass frame manufacturing industry, the connection between the temples and the frame usually relies on connecting posts, and in existing technologies, the connecting posts are mostly fixed to the frame by welding.

[0003] This type of welded fixing structure has obvious limitations:

[0004] The processing flow is limited. After the connecting posts are welded to the frame, the temples can only undergo subsequent surface treatments such as coloring after the basic processing of the overall frame is completed. It is impossible to process the temples separately, resulting in insufficient flexibility in the production process.

[0005] Production costs are relatively high. Because the temples cannot be processed independently, some processes need to be carried out simultaneously with the frames, which not only prolongs the overall production cycle but also increases material waste and equipment occupancy costs, hindering large-scale and efficient production.

[0006] Maintenance and replacement are inconvenient. Once the temples or connecting posts are damaged, the welded structure cannot be disassembled, and the entire frame often needs to be replaced, which increases the user's operating costs and does not conform to the trend of energy-saving and environmentally friendly product design.

[0007] In summary, the existing methods for fixing the connecting pins of eyeglass frames have room for improvement in terms of processing flexibility, production cost control, and subsequent maintenance. There is an urgent need for a connection structure that can optimize the above-mentioned problems. Utility Model Content

[0008] To address the shortcomings of the prior art, this utility model provides an eyeglass frame that facilitates lens replacement.

[0009] The technical solution adopted by this utility model is: an eyeglass frame that facilitates lens replacement, including a frame and clamp screws. The frame has slits on both sides, and an upper clamp and a lower clamp are provided at the ends of the slits. The upper clamp and the lower clamp are tightened and fixed together by clamp screws.

[0010] Furthermore, it also includes connecting pile segments and pile segment screws;

[0011] A clamping gap is left between the upper clamping plate and the lower clamping plate;

[0012] One end of the connecting post has a connecting part that extends into the clamping gap, and the other end is provided with a hinge part that connects to the temple of the mirror.

[0013] The lower clamping plate and the connecting part are fixedly connected by pile screws.

[0014] Furthermore, the connecting part includes a limiting part and a fastening part, the fastening part is provided with a first screw countersunk hole, and the lower clamp plate located below the fastening part is provided with a first internal thread hole;

[0015] The lower clamping plate is provided with a second countersunk hole for the screw head, and the upper clamping plate is provided with a second internal thread hole.

[0016] Furthermore, the connecting part and the hinge part are connected by an arc-shaped segment, and the hinge part is provided with a hinge hole.

[0017] Furthermore, the top of the hinge portion has an arc structure, and its side is provided with a limiting end face.

[0018] Furthermore, the shape of the connecting part is adapted to the clamping gap.

[0019] Furthermore, the connecting part, the hinge part, and the arc segment are integrally formed structures.

[0020] The beneficial effects of this utility model are:

[0021] 1. Enhanced processing flexibility and reduced production costs. The connecting posts and frame are detachable, allowing the temples to be processed and painted independently without needing to be produced simultaneously with the overall frame. This design reduces inter-process dependencies, shortens the production cycle, and lowers material waste and equipment occupancy costs, making it more suitable for large-scale production needs.

[0022] 2. Facilitates later maintenance and component replacement. When the temple or connecting posts are damaged, it is not necessary to replace the entire frame; only the corresponding post screws need to be removed to replace the damaged part individually. This not only reduces the user's usage and maintenance costs but also reduces the generation of waste parts, aligning with the principles of energy conservation and environmental protection.

[0023] 3. Balancing structural stability and ease of assembly. Tightening the upper and lower clamping plates with clamp screws, along with securing the connection with pile plate screws, ensures a stable connection between the pile plate and the frame, preventing loosening during use. Furthermore, the bolted connection method is simple to operate; assembly and disassembly do not require specialized welding equipment, improving the convenience of production and maintenance.

[0024] In addition to the objectives, features and advantages described above, this utility model has other objectives, features and advantages.

[0025] The present invention will now be described in further detail with reference to the accompanying drawings. Attached Figure Description

[0031] 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.

[0032] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0033] This invention provides an eyeglass frame that facilitates lens replacement.

[0034] In this embodiment, refer to Figure 1-4 The eyeglass frame that facilitates lens replacement includes a frame 1 and a clamp screw 2. The frame has cutouts 3 on both sides, and an upper clamp 4 and a lower clamp 5 are provided at the ends of the cutouts 3. The upper clamp 4 and the lower clamp 5 are tightened and fixed together by the clamp screw 2.

[0035] It also includes the connecting pile plate 7 and the pile plate screw 8;

[0036] A clamping gap 9 is left between the upper clamping plate and the lower clamping plate;

[0037] One end of the connecting post has a connecting part 10 that extends into the clamping gap, and the other end is provided with a hinge part 11 that connects to the temple of the mirror.

[0038] The lower clamping plate 5 is fixedly connected to the connecting part by post screws 8.

[0039] In the above technical solution, slits are provided on both sides of the integrated frame, and upper and lower clamps are provided at the ends of the slits. The clamps are tightened / loosened by clamp screws; when tightened, the clamps fix the lenses, and when loosened, the slits open, allowing direct removal and placement of the lenses. This allows users to quickly change lenses themselves, while avoiding damage to the lenses and frames caused by squeezing / prying.

[0040] In addition, a clamping gap is left between the upper and lower clamping plates. One end of the connecting piece (connecting part) extends into the gap and is fixed to the lower clamping plate by the piece screw. The other end (hinged part) is used to connect the temple; thus realizing the detachable connection between the frame and the temple.

[0041] It balances the convenience of lens replacement with the stability of temple connection. Damaged temples can be replaced separately without discarding the entire frame, reducing maintenance costs, and the assembly and disassembly are flexible.

[0042] The bolted connection between the connecting pins and the frame is detachable, which not only ensures structural stability but also breaks the limitations of traditional welding fixation, allowing the temples to be processed and replaced independently, simplifying lens replacement operations and reducing production and maintenance costs.

[0043] Specifically, the connecting part includes a limiting part 12 and a fastening part 13. The fastening part is provided with a first screw countersunk hole 14, and the lower clamp plate located below the fastening part is provided with a first internal screw hole 15.

[0044] The lower clamping plate is provided with a second countersunk hole 16, and the upper clamping plate is provided with a second internal thread hole 17.

[0045] In this embodiment, the fastening part of the connecting part is provided with a first countersunk screw head, and the lower clamping plate is provided with a corresponding first internal threaded hole (for the use of the piling plate screw); the lower clamping plate is provided with a second countersunk screw head, and the upper clamping plate is provided with a corresponding second internal threaded hole (for the use of the clamping plate screw). The countersunk screw head can hide the screw head and at the same time keep the screw head on the lower side when worn, thus playing a hiding role.

[0046] The screw head is recessed into a countersunk hole to prevent the protrusion from scratching the skin or snagging on clothing, thus improving wearing comfort and a neat appearance; at the same time, it ensures the screw connection is secure and prevents loosening.

[0047] Specifically, the connecting part and the hinge part are connected by an arc-shaped segment 18, and the hinge part is provided with a hinge hole 19.

[0048] In this embodiment, the curved section conforms to the side of the face, reducing the pressure of the frame on the cheeks; the hinge hole ensures that the temples can rotate flexibly to adapt to different wearing angles and improve the wearing fit.

[0049] Specifically, the top of the hinge is an arc structure, and a limiting end face 20 is provided on its side.

[0050] In this embodiment, the top of the hinge is provided with an arc structure and the side is provided with a limiting end face; the arc structure avoids sharp corners, and the limiting end face restricts the rotation angle of the temple (to prevent excessive opening and closing).

[0051] Specifically, the shape of the connecting part is adapted to the clamping gap.

[0052] In this embodiment, there is no loose space between the connecting part and the gap, which prevents the connecting piece from shaking, ensures the stability of the connection between the temple and the frame, and prevents the temple from shifting when worn.

[0053] Specifically, the connecting part, the hinge part, and the arc segment are integrally formed structures.

[0054] In this embodiment, the connecting part, hinge part, and arc segment are manufactured using an integral molding process (such as stamping or injection molding), without any splicing gaps.

[0055] Attention all technical personnel: Although this utility model has been described according to the specific embodiments above, the concept of this utility model is not limited to this utility model. Any modification that utilizes the concept of this utility model will be included within the scope of protection of this patent right.
