Description

Glasses with interchangeable lenses

Technical field

The utility model relates to the field of eyeglasses, in particular to eyeglasses with interchangeable lenses.

Background technique

With the improvement of living standards, more and more people begin to pay attention to eye protection, such as wearing sunglasses in summer; in addition, as learning pressure increases, Chinese myopia also increases significantly, and the age of people suffering from myopia is getting younger and younger These factors directly led to a substantial increase in demand for glasses. Although the quality of the spectacle frame has been greatly improved, the service life of the spectacles has been greatly extended, but for the lively and active young people who often perform sports, they still often encounter unexpected breakage or breakage of the lens. When changing lenses, this usually requires the use of a screwdriver or other tool of appropriate size. This is cumbersome and time-consuming for most eyewear wearers.

Utility model content

The purpose of the utility model is to provide glasses with a simple structure and more convenient lens replacement.

The technical solution of the utility model is as follows: a kind of glasses with replaceable lenses, including a frame, temples connected to both sides of the frame, and a lens assembly detachably matched with the frame, characterized in that the lens assembly includes an inner ring with the frame Lenses fixed on the inner side of the frame with respect to its detachable frame and detachable frame, the outer edge of the frame is provided with a convex structure, and the corresponding position on the inner side of the lens frame is provided with a concave that is engaged with the convex structure Slot, the frame is also provided with a plug-in part, and the mirror frame is provided with a plug-in slot that engages with the plug-in part after the convex structure is snapped into the groove, the outer wall of the plug-in part An elastic portion capable of radially elastically deforming when it is inserted into the insertion groove is provided.

The utility model is further provided that the frame includes a frame body adapted to the frame and a limiting portion extending outward with respect to the frame body, and the limiting portion is adapted to the inner ring of the frame When it is set against the back of the frame.

The utility model is further configured such that the insertion slot is located on the outside and back of the lens frame, and the groove is located on a corresponding position on the inside of the lens frame.

The utility model is further configured to further include a nose bridge provided on the limiting portion. The nose bridge includes a pair of opposed and spaced-apart beams, and the interval of the pair of beams is sequentially reduced from bottom to top and corresponds The upper ends of the two are set against each other.

The utility model is further provided that the frame is made of PA12 material.

The utility model is further configured to further include mirror legs provided on both sides of the frame, and the mirror legs are provided with energy stones at the ends thereof.

The utility model has the following beneficial effects: when it is used for the first time, the buckle connection at the first point is achieved by placing the convex structure in the corresponding groove, and then the entire lens assembly is embedded in the frame until the limit portion resists At the back of the frame, the insertion part is inserted into the insertion slot in the above process to achieve a fixed connection at the second point. At this time, the lens assembly can be firmly fixed on the frame, and the elastic part can be set to make the second point The fixed connection is more tight and not easy to detach. When the lens is accidentally damaged, you can directly detach the insertion part from the frame to realize the disassembly of the entire lens assembly, which is convenient to use.

detailed description

The specific implementation of the present invention will be further described in detail below in conjunction with the drawings and embodiments. The following embodiments are used to illustrate the present invention, but are not used to limit the scope of the present invention.

With reference to FIGS. 1 to 3, an eyeglass with interchangeable lenses 21 includes a frame 1, a temple 4 connected to both sides of the frame 1, and a lens 21 assembly 2 detachably fitted with the frame 1, the lens 21 assembly 2 includes The inner ring of the frame 1 is adapted to the shape and size of the frame 22, and the detachable frame 22 and the lens 21 fixed inside the frame 22. In this embodiment, the frame 1 and the frame 22 are made of PA12. The frame 22 A convex structure 23 is provided on the outer edge of the frame, and a corresponding groove 11 on the inner side of the frame 1 is engaged with the convex structure 23. The frame 22 is also provided with a plug-in portion 24. The frame 1 is provided with After the convex structure 23 is snapped into the groove 11, the plug slot 12 is mated with the plug portion 24. The outer wall of the plug portion 24 is provided when it is plugged into the plug slot 12 An elastic portion 25 capable of elastic deformation in the radial direction. The elastic portion 25 is made of an elastic rubber material and is sleeved on the insertion portion 24. The frame 22 includes a frame body 221 adapted to the lens frame 1 and a limiting portion 222 extending outward with respect to the frame body 221. The two constitute a frame 22 with an L-shaped cross section. 22 fits against the inner ring of the frame 1 and is placed against the back of the frame 1, the insertion slot 12 is located on the outside and back of the frame 1, and the groove 11 is located at a corresponding position on the inside of the frame 1, ie The insertion groove 12 is disposed as far away from the groove 11 as possible in the lens frame 1.

In this embodiment, the nose bridge 3 disposed on the limiting portion 222 is also included. The nose bridge 3 includes a pair of

opposed beams

31 and 32 spaced apart from each other. The upper and lower ends are arranged in turn and the corresponding two upper ends are set against each other. In this way, the nose bridge 3 provided with a structure has a certain elasticity and is more comfortable to wear. It also includes a temple 4 provided on both sides of the frame 1, the temple 4 The upper part is provided with an energetic stone (omitted in the drawing) at the end. When people's eyes are focused on reading work for a long time and can't rest, the energetic stone can have an anti-radiation effect on mobile phones and various electrical products.

The utility model has the following beneficial effects: when it is used for the first time, the buckle connection at the first point is realized by placing the convex structure 23 in the corresponding groove 11, and then the entire lens 21 assembly 2 is embedded in the frame 1, Until the limiting portion 222 abuts against the back of the frame 1, in the above process, the insertion portion 24 is inserted into the insertion groove 12 to achieve a fixed connection at the second point, and the lens 21 assembly 2 can be firmly fixed to the frame 1 On the upper side, the arrangement of the elastic portion 25 can make the fixed connection at the second point more secure and not easy to detach. When the lens 21 is accidentally damaged, the insertion portion 24 can be directly detached from the frame 1 to realize the entire lens 21 assembly 2 The disassembly is easy to use.

The above is only the preferred embodiment of the utility model. It should be pointed out that for those of ordinary skill in the art, without departing from the technical principles of the utility model, several improvements and modifications can be made. The above assumption These improvements and modifications should also be regarded as the scope of protection of the present invention.
