Triangular screwless hinge structure

Abstract

The utility model relates to glasses technical field especially triangle screwless hinge structure. The traditional glasses hinge structure is more, and is mostly welding hinge or screw connection, is more cumbersome, and long -time use screw wear will appear loosening even the defect of falling off. Triangle screwless hinge structure, including have glasses frame etc. ; The glasses frame is fixedly connected with two hinges, two symmetry sets up, and the both ends of two legs are provided with the ring of two legs close to glasses frame. Through the coincidence of the center of the ring on the leg and the center of the triangular limiting structure on the hinge, the leg and the hinge can be combined without screw and welding point, the structure is novel, simple, light and compact, the center of the shaft is a hollow structure, which can avoid the traditional screw wear loosening or even falling off, and prolong the service life.

Description

Technical Field

[0001] This utility model relates to the field of eyeglasses technology, and in particular to a triangular screwless hinge structure. Background Technology

[0002] Existing eyeglass hinge structures are quite traditional, mostly consisting of welded hinges or screw connections, making the glasses rather heavy. Moreover, in this type of screw hinge structure, the screws that play a connecting role are prone to loosening or even falling off during use. Utility Model Content

[0003] To address the shortcomings or deficiencies of the existing technology, this utility model provides a triangular screwless hinge structure, which enables the support leg and the hinge frame to be connected without screws or solder joints. The structure is novel, simple, and lightweight, and the center of the pivot is hollow, which can extend the service life.

[0004] A triangular screwless hinge structure includes a mirror frame, on which two hinge brackets are fixedly connected. The two hinge brackets are symmetrically arranged, and each hinge bracket is fitted with a support leg. Each support leg has a ring at one end near the mirror frame.

[0005] Preferably, the frame also includes nose pads, with two nose pads fixedly connected to the frame and arranged symmetrically.

[0006] Preferably, the system also includes anti-slip sleeves, with each of the two legs covered by the anti-slip sleeves, and the sides of the two anti-slip sleeves that are close to each other having anti-slip textures.

[0007] The beneficial effects of this utility model are as follows: This utility model uses a hinged connection structure consisting of a frame, hinges, and temples. Two hinges are provided at both ends of the frame. Both hinges are made of elastic metal and have a triangular limiting structure. By aligning the center of the ring on the leg with the center of the triangular limiting structure on the hinge, the leg and the hinge can be connected without screws or welds. The structure is novel, simple, and lightweight. Furthermore, the center of the pivot is hollow, which avoids the wear, loosening, or even falling off of traditional screws, thus extending the service life. Attached Figure Description

[0013] All standard parts used in this invention can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, welding, and bonding that are mature in the existing technology, and will not be described in detail here.

[0014] Example 1

[0015] Triangular screwless hinge structure, such as Figures 1-4 As shown, the mirror includes a frame 1, on which two hinges 2 are fixedly connected. The two hinges 2 are arranged symmetrically, and each hinge 2 is fitted with a support leg 3. Each support leg 3 has a ring at one end near the frame 1.

[0016] It also includes nose pads 4, with two nose pads 4 being snapped onto the frame 1, and the two nose pads 4 being arranged symmetrically.

[0017] It also includes anti-slip sleeves 5, with anti-slip sleeves 5 covering both of the two legs 3, and anti-slip textures provided on the side of the two anti-slip sleeves 5 that are close to each other.

[0018] This invention utilizes a hinged connection structure consisting of a frame 1, hinges 2, and temples. Two hinges 2, made of elastic metal, are located at both ends of the frame 1. Each hinge 2 has a triangular limiting structure. The rings on the two temples 3 are located within the triangular limiting structures on the two hinges 2, ensuring that the center of the ring on the temple 3 coincides with the center of the triangular limiting structure on the hinge 2. The point where the center of the ring on the temple 3 coincides with the center of the triangular limiting structure on the hinge 2 is the pivot center, which is a hollow structure. The two hinges 2, being at opposite ends, respectively block the two temples 3. Swinging the two temples 3 towards each other allows the glasses to fold up. Thus, by aligning the center of the ring on the temple 3 with the center of the triangular limiting structure on the hinge 2, a screwless and weld-free connection between the temples 3 and the hinges 2 is achieved. The structure is novel, simple, and lightweight. Furthermore, the hollow pivot center avoids the wear, loosening, or even detachment of traditional screws, extending the service life.

[0019] Both nose pads are made of rubber and can support the eyeglasses frame by supporting it on the bridge of the user's nose.

[0020] Both anti-slip sleeves 5 are made of rubber, and the sides that are close to each other are provided with anti-slip textures, so that the user can wear the glasses more stably and they are not easy to slip off.

[0021] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
