Description

Change lens structure of glasses

This creation is related to a lens changing structure for glasses, especially a kind of lens changing structure that can be easily changed by flipping the lens frame diagonally.

According to the fact that the glasses on the market have many functions and styles, they are divided into rimmed glasses and rimless glasses according to their frame type, so that consumers can choose the glasses they need according to their preferences and purposes. Existing glasses are still dominated by rimmed glasses. The structure of rimmed glasses is mainly provided with two opposite lens assembly holes in the frame, and openings are respectively provided on both sides of the frame to communicate with the two lens assembly holes. The side openings are respectively provided with locking ears at the upper and lower edges, and corresponding locking holes are respectively provided on the two locking ears, and the locking holes of the two locking ears are screwed through and locked; In this way, when the lens is to be assembled in the two lens assembly holes of the frame, the upper and lower parts of the opening of the frame are applied with reverse force to enlarge the opening spacing of the frame, thereby expanding the aperture of the lens assembly hole , In order to put the lens into the lens assembly hole of the frame. Then, the user releases the force applied to the upper and lower parts of the opening of the frame, and then uses screws to pass through the locking holes of the locking ears on the upper and lower edges of the opening to align the two locking ears with the lock, and Close the opening between the two locking ears so that the lens is firmly fixed in the lens assembly hole of the frame.

Therefore, according to the structure design of the existing spectacles frame, when you want to disassemble and replace the lens, you must use a special screwdriver to loosen the screws and open the side opening of the frame before assembling or removing the lenses. The body is small and positive. If the screws are assembled or disassembled carelessly, the screws are easy to fall and lose, and their threads are fine, and the threads may collapse due to careless force, or the grooves where the force is applied by the screwdriver may be damaged. The assembly process requires a screwdriver that matches the screw. Once there is no matching screwdriver on hand, the screw assembly operation of the screw cannot be carried out. This will also cause great inconvenience in the assembly operation, resulting in troubles and troubles in the use of changing chips. Missing.
