Description

Technical Field

[0001] The utility model relates to the technical field of glasses frames, in particular to a glasses frame with a structure for preventing lenses from falling off. Background Art

[0002] Glasses are composed of lenses and frames. They are used to improve vision, protect eyes or for decorative purposes. Glasses can correct a variety of vision problems, including myopia, hyperopia, astigmatism, presbyopia, strabismus or amblyopia. With the increase in the types of glasses, more and more people are wearing glasses. Wearing glasses mainly changes the vision of the eyes through the lenses. Therefore, it is particularly important to prevent the lenses from falling off and to stabilize the frames.

[0003] For example, a glasses frame with a lens-proof structure having a publication number of CN218956937U fixes the connecting arm up and down by a nut, and the lens is clamped in the fixing groove to make the lens more stable. The connecting arm after the nut is tightened makes the frame and the lens installed more tightly, and the lens will not shake and fall from the frame at will. At the same time, the rubber layer inside the fixing groove will be close to the lens. The rubber material is soft, which can reduce the impact of the lens due to falling and better protect the lens. However, the above-mentioned glasses frame still has the following deficiencies in actual use: a fixing groove is provided inside the frame, and a rubber layer is bonded inside the fixing groove. Although the impact of the lens due to falling can be reduced and the lens can be prevented from falling, after the rubber is used for a long time, it is exposed to environmental factors such as air, moisture, light, temperature, etc. for a long time, which will inevitably cause aging of the rubber layer and reduce the protective effect of the lens. Moreover, the rubber layer is fixedly bonded inside the frame, which is not convenient for replacement. Therefore, most people directly replace the frame, which will cause unnecessary waste. Therefore, a glasses frame with a lens-proof structure is needed to solve the above problems. Utility Model Content

[0004] The purpose of the present invention is to solve at least one of the above technical deficiencies.

[0005] Therefore, one purpose of the present invention is to provide a spectacle frame with a lens-preventing structure to solve the problems mentioned in the background art and overcome the deficiencies in the prior art.

[0006] In order to achieve the above-mentioned objectives, an embodiment of the utility model on one hand provides a glasses frame with a lens-preventing structure for falling off, comprising an upper frame, the back of the upper frame is rotatably connected to a temple via a hinge, the bottom of the upper frame is rotatably connected to a lower frame via a hinge, the lower frame is screwed to the upper frame via bolts, a lens is arranged between the upper frame and the lower frame, the top and bottom of the lens are fixedly connected to a snap-in protrusion, the inner sides of the upper frame and the lower frame are provided with an assembling groove, the inner wall of the assembling groove is slidably connected to an assembling plate, one side of the assembling plate is rotatably connected to a threaded fastener, the assembling plate is screwed to the upper frame and the lower frame via the threaded fastener, the inner side of the assembling plate is provided with a snap-in groove, the inner wall of the snap-in groove is fixedly connected to a rubber pad, and the snap-in protrusion is snap-in to the assembling plate via the snap-in groove.

[0007] It is preferred that the shape and size of the clamping groove and the clamping protrusion are matched, and the clamping protrusion is consistent with the material of the lens. The number of the rubber pads is two, and the two rubber pads are symmetrically distributed on both sides of the clamping protrusion. The technical effect achieved by adopting the above technical solution is: the assembly plate is screwed with the upper frame and the lower frame through the threaded fastener, and the clamping protrusion is clamped with the assembly plate through the clamping groove, so that the lens can be stably assembled between the upper frame and the lower frame, the lens can be positioned, and the lens can be prevented from falling out of the frame.

[0008] Preferably, any of the above schemes is that the assembly plate is slidably connected to the upper frame and the lower frame through an assembly groove. A threaded hole is provided inside the assembly plate, and the threaded fastener is adapted to the thread pitch of the threaded hole. A positioning hole is provided inside the assembly groove, and a positioning pin is fixedly connected to the top of the assembly plate, and the positioning pin is engaged with the upper frame and the lower frame through the positioning hole. The technical effect that can be achieved by adopting the above technical scheme is: when the rubber pad ages, the bolts between the upper frame and the lower frame can be disassembled, and then the lower frame can be disassembled, the lens can be taken out, and then the threaded fastener can be disassembled, and finally the assembly plate can be pulled out from the assembly groove for replacement, and only the assembly plate needs to be replaced, and the entire frame does not need to be replaced, which will not cause unnecessary waste of resources.

[0009] Compared with the prior art, the advantages and beneficial effects of the utility model are:

[0010] The assembling plate is screwed to the upper frame and the lower frame through threaded fasteners, and the clamping protrusion is clamped to the assembling plate through the clamping groove, so that the lens can be stably assembled between the upper frame and the lower frame, the lens can be positioned, and the lens can be prevented from falling off the frame due to falling. When the rubber pad is aged, the bolts between the upper frame and the lower frame can be removed, and then the lower frame can be removed, the lenses can be taken out, and then the threaded fasteners can be removed, and finally the assembling plate can be pulled out from the assembling groove and replaced. Only the assembling plate needs to be replaced, and the entire frame does not need to be replaced, which will not cause unnecessary waste of resources. BRIEF DESCRIPTION OF THE DRAWINGS
