[0023] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model are described clearly and completely below with reference to the accompanying drawings. Obviously, the specific details described below are only a part of the embodiments of this utility model, and this utility model can be implemented in many other embodiments different from those described herein. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly attached to the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0026] Please see Figures 1 to 3 In one embodiment, a replaceable hinge structure 100 includes: a head 1, a hinge boss 3, a temple 4, and a fastening assembly 5.

[0027] One end of the frame 1 is provided with a fixing nail 2, and the frame 201 is provided with a positioning pit. The fixing nail 11 is driven into the positioning pit so that the frame 1 and the frame 201 are fixedly connected.

[0028] In the connection structure embodiment of the hinge boss 3, one end of the hinge boss 3 is rotatably connected to the frame head 1 to realize the opening and closing of the temple 4 relative to the frame. This end of the hinge boss 3 can extend obliquely upward to ensure the rotation space of the temple 4. A flange 31 protrudes from the bottom of the hinge boss 3, and a groove 41 matching the flange 31 is formed at the top of one end of the temple 4. The fastening assembly 5 passes through the bottom of one end of the temple 4 and is fixedly connected to the hinge boss 3, thereby reliably fixing the temple 4 to the hinge assembly. Through this combination of insertion and fastening, the assembly is very firm and not easy to loosen.

[0029] In one embodiment, the bottom of one end of the temple 4 extends inward to form a mounting cavity 42 communicating with the groove 41, and the fastening assembly 5 passes through the mounting cavity 42. This structure allows the fasteners to be hidden inside the temple 4, avoiding exposure that would affect the appearance, while improving overall strength and safety.

[0030] Furthermore, the end face of the flange 31 extends into the hinge boss 3 and is provided with a groove 32. The fastening assembly 5 includes a locking member 51 and an elastic member 52. The locking member 51 is provided with a snap-fit ​​connector 511, which passes through the mounting cavity 42 and the groove 41 and engages with the groove 32. A first step 421 is provided inside the mounting cavity 42, and the top end of the elastic member 52 abuts against the first step 421, while the bottom end abuts against the locking member 51. The elastic member 52 is sleeved inside the locking member 51. In the locked state, this structure maintains a constant preload force through the elastic member to prevent loosening, thereby achieving a fixed connection between the hinge boss 3 and the temple 4.

[0031] The locking component 51 also includes a lock head 512, which is fixedly connected to one end of the locking head 511. The vertical cross-sectional area of ​​the lock head 512 is larger than that of the locking head 511, forming a larger force-bearing area, making the assembly more stable and easier to install manually or with tools.

[0032] In one embodiment, the locking connector 511 includes four locking arms 513. The bottom ends of the locking arms 513 are fixed to the locking head 512 at intervals. The cross-section of the locking arms 513 is a quarter-annular shape, and the four locking arms 513 together form a ring. During the locking process, the elastic force of the elastic element 52 can cause the four locking arms 513 to pop outward, thereby firmly abutting against the locking groove 32, so that the temple 4 and the hinge boss 3 are tightly connected. In other embodiments, the shape and number of locking arms 513 can be set according to the actual situation, but multiple locking arms 513 need to be combined into a ring.

[0033] A hook 514 is provided on the outer side of the top of the locking arm piece 513, and the hook 514 engages with the locking groove 32. The mounting cavity 42 also has a second step 422, which is spaced apart from the first step 421. The locking head 511 abuts against the second step 422. The elastic element 52 is a spring, with one end abutting against the locking head 512 and the other end abutting against the first step 421. The elastic pre-tightening maintains a continuous locking force between the locking head 511 and the locking groove 32, thereby preventing loosening or falling off during use. This mating structure makes the connection between the hinge boss 3 and the temple 4 more stable and prevents loosening due to vibration.

[0034] The flange 31 and the groove 41 have the same shape and can be made into different shapes such as rectangle, square, polygon, circle or oval according to product design requirements to adapt to the connection structure of different styles of temples 4, enhancing versatility and decoration. The outer side of the lock head 511 can be set with a display area for laser engraving or printing brand logos, so that the product can maintain functionality while taking into account visual aesthetics.

[0035] This utility model also discloses a pair of glasses 200, including a frame 201 and the aforementioned replaceable hinge structure 100. Positioning pits are provided on both sides of the frame 201 along the thickness direction, and the fixing nails 11 of the head 1 are driven into the positioning pits to fix the head 1 and the frame 201.

[0036] Please see Figure 1 The eyeglasses 200 of this utility model achieve a stable connection between the head 1 and the frame 201 through a snap-fit ​​engagement; the temple 4 and the hinge boss 3 are connected by a plug-in and fastening assembly to achieve a standardized interface design. This structure is easy to install, rotates smoothly, and has a simple appearance, and can be widely used in different types of eyeglasses 200 products.

[0037] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0038] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications, substitutions, and improvements without departing from the concept of this utility model, and these should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the claims.
