[0023] 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.

[0024] For reference as follows Figures 1-3 The present invention will be described as follows:

[0025] Example: A connection structure between a nose bridge and an eyeglass frame, including a nose bridge 1, which is located at the center of the eyeglasses and serves to connect the two eyeglass frames and support the wearer's nose.

[0026] Long, fixed strips 2 extend from the left and right ends of the bridge of the nose 1, respectively. The left and right ends of the rear side of each fixed strip 2 have rearward-protruding insertion posts 3. These insertion posts 3 are key elements for achieving rapid assembly. Their protrusion height must ensure a secure insertion into the insertion holes 8 of the eyeglass frame 7, but not be too long to cause assembly difficulties or affect the overall compactness and usability of the eyeglasses; their diameter must form an appropriate interference fit with the inner diameter of the insertion hole 8 to achieve a firm connection.

[0027] It also includes two eyeglass frames 7, which are the main structure that supports the lenses and provides protection and vision correction for the wearer's eyes. Two fixing strips 2 are fixedly connected to the two eyeglass frames 7 respectively. The upper left and right ends of the eyeglass frames 7 are respectively provided with insertion holes 8 corresponding to the insertion posts 3 (the position, size, and depth of these insertion holes 8 are precisely matched to the insertion posts 3. The accuracy of the position ensures that the fixing strips 2 can accurately align with the eyeglass frames 7 during assembly, without any offset or misalignment; the size of the holes is designed according to the diameter of the insertion posts 3, forming a suitable interference fit, so that the insertion posts 3 can fit tightly after insertion, preventing loosening; the depth is sufficient to accommodate the insertion posts 3, ensuring the stability of the connection). The fixing strips 2 are located on the front side of the eyeglass frames 7 and fit tightly against them.

[0028] Assembly process:

[0029] During assembly, first align the fixing strips 2 at both ends of the nose bridge 1 with the corresponding positions on the two eyeglass frames 7. Since the fixing strips 2 are elongated, they provide some guidance when in contact with the eyeglass frames 7, initially guiding the assembly direction. Then, align the insertion pins 3 on the fixing strips 2 with the insertion holes 8 on the eyeglass frames 7, and gently apply pressure to gradually insert the insertion pins 3 into the insertion holes 8. Because an interference fit is used, some resistance will be felt as the insertion pins 3 are inserted; this is normal and indicates that the two are fitting tightly. During insertion, no complex tools or professional welding equipment are needed; workers can complete the process simply by hand, making it simple and convenient.

[0030] Efficiency improvements are reflected in:

[0031] Compared to traditional methods of connecting the nose bridge to the eyeglass frame, such as welding or screw fixing, this invention offers significant efficiency advantages. Welding requires considerable time for workers to adjust the welding position and control welding parameters due to the limited welding space. Furthermore, post-weld processing such as grinding is necessary, making the entire process time-consuming and labor-intensive. Screw fixing, on the other hand, is inconvenient for workers to tighten due to limited installation space, and is prone to problems such as stripped screws, also affecting assembly progress. This connection structure only requires inserting the insertion post 3 into the insertion hole 8, completing the fixing connection in one step. This greatly simplifies the assembly process, reduces assembly time, and thus improves the assembly efficiency of the nose bridge 1 and eyeglass frame 7. It can meet the needs of large-scale production, reduce production costs, and bring greater economic benefits to eyewear manufacturers.

[0032] The upper side of the fixing strip 2 is provided with a rearwardly protruding clamping strip 6. When the fixing strip 2 is assembled with the eyeglass frame 7, the fixing strip 2 fits against the front side of the eyeglass frame 7, at which time the clamping strip 6 is precisely clamped around the upper edge of the eyeglass frame 7. The shape and size of the clamping strip 6 are precisely adapted to the contour of the upper edge of the eyeglass frame 7. It must ensure a tight fit without leaving too large a gap that would cause the connection to loosen, and it must also have a certain degree of flexibility to accommodate slight dimensional deviations that may occur during assembly, so as to smoothly complete the clamping action.

[0033] This clamping structure enhances the connection stability between the fixing strip 2 and the eyeglass frame 7 from multiple dimensions. Vertically, the clamping strip 6 applies downward pressure to the upper edge of the eyeglass frame 7, combining with the pressure exerted by the fixing strip 2 on the front side of the eyeglass frame 7 to effectively prevent the eyeglass frame 7 from shifting upwards relative to the fixing strip 2. Compared to a connection solely relying on the insertion post 3 and the insertion hole 8, the presence of the clamping strip 6 makes the entire connection structure more stable, better able to withstand various external impacts on the glasses during daily use, such as accidental drops or collisions, reducing the risk of the eyeglass frame 7 separating from or loosening from the bridge 1.

[0034] The corresponding section of the fixing strip 2 is widened to accommodate the insertion post 3. This is because the insertion post 3 requires sufficient space for its placement, and its diameter, along with surrounding auxiliary structures (such as possible small reinforcing ribs to enhance its strength and stability), necessitates a large lateral area. By widening the corresponding section of the fixing strip 2, not only is suitable space provided for the insertion post 3, allowing it to be securely mounted on the fixing strip 2, but this also ensures that during assembly, when the insertion post 3 is subjected to the pressure of being inserted into the insertion hole 8, this section of the fixing strip 2 has sufficient strength to support it, preventing deformation or breakage and ensuring smooth assembly.

[0035] Correspondingly, the location of the insertion hole 8 on the eyeglass frame 7 can also be widened. This is to echo the widened part of the fixing strip 2, ensuring that the insertion hole 8 itself has sufficient space to meet its precision requirements. For example, in manufacturing processes such as drilling or injection molding, a larger space facilitates the operation of tools or molds, reduces processing errors, and ensures the accuracy of parameters such as the diameter and depth of the insertion hole 8. On the other hand, when the widened part of the eyeglass frame 7 is assembled with the fixing strip 2, it can better withstand the impact force brought by the insertion of the insertion post 3, enhance the overall rigidity of the connection part, and improve the reliability of the connection.

[0036] The length of the connector pin 3 is less than or equal to the length of the connector hole 8. This detail is crucial to the appearance and safety of the eyeglasses. If the length of the connector pin 3 is greater than the length of the connector hole 8, the connector pin 3 will protrude from the back side of the eyeglass frame 7 after assembly. This not only affects the overall aesthetics of the eyeglasses, making them look rough and unrefined, but also poses a potential risk of scratching the wearer's skin during wear. When the length of the connector pin 3 is less than or equal to the length of the connector hole 8, it ensures a smooth and even appearance after assembly, while eliminating the safety hazard caused by the protruding connector pin 3, making it more comfortable and safer for the wearer.

[0037] The fixing strip 2 has a rearwardly protruding insertion post 3 in the middle. A corresponding insertion hole 8 is provided on the eyeglass frame 7. This design further optimizes the mechanical performance of the connection structure. In addition to the connection support provided by the insertion posts 3 and insertion holes 8 at both ends, this set of insertion structures in the middle is equivalent to adding another stable support point in the connection area between the fixing strip 2 and the eyeglass frame 7.

[0038] The nose bridge 1 and the fixing strip 2 are integrated into one piece, made of metal or plastic. This integrated structure avoids problems such as loose connections and instability that may occur with separate connections, enhancing the overall coherence and stability. In terms of material selection, metal materials such as stainless steel and aluminum alloys can be used. Metal materials have high strength and hardness, can withstand greater external impacts, and are suitable for making eyeglasses with high durability requirements and relatively rigid designs. Their good processing performance also facilitates the precise molding of intricate structures such as the insertion post 3 and the clamping strip 6 during manufacturing. Alternatively, plastic materials such as engineering plastics and polycarbonate can be used. Plastic materials have the advantages of being lightweight, low-cost, and highly malleable, meeting the needs of different colors and shapes. Moreover, through reasonable mold design, complex nose bridge 1 and fixing strip 2 structures can be manufactured conveniently and quickly, providing more possibilities for diverse eyeglass designs.

[0039] The nose bridge 1 is provided with an insertion hole 4 and a positioning hole 5 that run through its front and rear sides. There are two insertion holes 4 and one positioning hole 5 located between the two insertion holes 4.

[0040] It also includes a nose bridge 9, which has a near-V-shaped structure. Both ends of the nose bridge 9 pass through two insertion holes 4 and extend to the lower rear side of the nose bridge 1. This insertion method creates a tight spatial connection between the nose bridge 9 and the nose bridge 1. The position and size of the insertion holes 4 are precisely matched to the dimensions of the two ends of the nose bridge 9, ensuring that the nose bridge 9 can pass through smoothly without excessive gaps that could cause wobbling or displacement. The position of extending to the lower rear side of the nose bridge 1 allows the force exerted by the nose bridge 1 to be reasonably distributed when the nose bridge 9 provides nasal support, avoiding excessive local pressure that could damage the nose bridge 1. It also utilizes the structural rigidity of the nose bridge 1 to stabilize the support of the nose bridge 9.

[0041] The nose bridge 9 has a nose bridge body 91 installed at each end. The installation method of the nose bridge body 91 usually needs to balance sturdiness and replaceability. Common installation methods may include snap-fit ​​connection, threaded connection, etc.

[0042] The nose support 9 has a positioning post 92 in the middle that inserts into the positioning hole 5. The size and shape of the positioning post 92 are precisely matched to the positioning hole 5. Its diameter is slightly larger than the inner diameter of the positioning hole 5 to achieve an interference fit (to achieve a fixed connection), ensuring that the nose support 9 is accurately fixed on the bridge of the nose 1. The height of the positioning post 92 is also carefully designed, ensuring that it can be inserted deeply into the positioning hole 5 for stable positioning, but not so long as to affect the overall assembly convenience of the nose support 9 or adversely affect the structural strength of the bridge of the nose 1. During assembly, the positioning post 92 is first aligned with the positioning hole 5. As the nose support 9 is gradually installed, the positioning post 92 is inserted into the positioning hole 5 and locked tightly. This process provides additional positioning protection for the nose support 9, preventing it from shifting in the front-back or left-right directions during use, so that the nose support 9 and the bridge of the nose 1 form a tight and stable whole.

[0043] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
