Description

Eyeglass change structure

This creation is about a lens changing structure, especially in the process of assembling or replacing the lens, not only does not need to prepare a corresponding tool set, which is simpler and more convenient, and also makes the assembly work faster. That is, the innovative designer of the lens changing structure that completes the assembly and has more practical and effective characteristics in its overall application.

According to the use of glasses, it can be divided into myopia glasses, reading glasses, sunglasses, work goggles, etc., so that users can choose to use myopia glasses to correct myopia, or use presbyopic glasses to correct presbyopia, or use sunglasses to block sunlight. Or use working goggles to protect the eyes; and the various types of glasses, regardless of the application, the basic structure is set in the lens frame, and the temples are pivotally connected to the sides of the frame to complete The assembly of the glasses is combined.

Among them, in the case of the commonly used glasses, the nose pads are arranged at the position between the frames, and the combination of the frame and the lens is respectively provided with corresponding lens assembly holes at the two ends of the frame, and the lens assembly holes are respectively arranged. The outer side is formed with a locking end that needs to be screwed and fixed by a screwing component. After the lens is ground into a corresponding lens assembly hole, the lens is sleeved into the lens assembly hole and screwed on the outer side of the lens assembly hole. The component is screwed and fixed to the locking end, so that the lens can be stably fixed in the lens assembly hole without falling off, and the user can wear the wearing glasses to achieve the intended use effect.

However, although the above-mentioned glasses can achieve the intended effect of fixing and fixing the lens to the frame, it is also found in the actual operation and use thereof that when the lens is assembled and positioned in the lens assembly hole, the screw end is required to be used for the locking end. The combination of the screw and the fixing can prevent the lens from falling off, so that it is not only required to use the tool set to screw the screw component during assembly and assembly, but also causes it to be extremely inconvenient and time consuming in assembly and assembly. As a result, there is still room for improvement in the overall structural design.

The reason is that the creators have in view of this, and have been rich in design and development and practical production experience of the relevant industries for many years, researching and improving the existing defects, and providing a kind of glasses changing structure, in order to achieve better practical value.

The main purpose of this creation is to provide a lens changing structure, which is mainly used in the process of assembly, assembly or replacement of the lens, which not only does not need to prepare a corresponding tool set, can be more convenient and convenient, and can also make the assembly work more The assembly is completed quickly, and the utility model is more effective in its overall application.

The main purpose and effect of the creation of the lens replacement structure are achieved by the following specific technical means:

It mainly includes a frame, a slider and a lens; among them:

The frame frame has a nose portion protruding downwardly, and a corresponding inlay groove is formed on the lower edge of the frame corresponding to the two sides of the nose beam portion, and a sliding segment is formed on both ends of the frame frame. , the outer end of the sliding section is connected with a pivoting arm;

The slider is formed with a sleeve groove corresponding to the sliding section of the frame, so that the slider is combined with the sliding section sleeve by the sleeve, so that the slider can slide on the sliding section, and the sliding a positioning convex portion is convexly protruded toward a side of the nose bridge portion;

The lens has an upper edge for inserting into the embedding groove of the frame, and a positioning recess corresponding to the positioning convex portion of the slider corresponding to the outer side of the lens is formed with a phase-locking combination.

In order to make the technical content, creative purpose and the effect achieved by this creation more complete and clear, please elaborate below, and please refer to the drawings and drawings:

First of all, please refer to the schematic diagram of the three-dimensional decomposition structure of the first figure. The creation mainly includes a frame (1), a slider (2) and a lens (3);

The frame (1) has a nose bridge portion (11) protruding downwardly from the middle portion thereof, and a corresponding recessed groove is formed on the lower edge of the frame (1) corresponding to the two sides of the nose bridge portion (11). 12) Further, a sliding section (13) is formed on both ends of the frame (1), and a temple (14) is pivotally connected to the outer end of the sliding section (13).

The slider (2) is formed with a sleeve groove (21) corresponding to the sliding section (13) of the frame (1), so that the slider (2) and the sliding section (21) 13) The sleeve is combined to allow the slider (2) to slide on the sliding section (13), and a positioning protrusion is protruded on a side of the slider (2) facing the nose bridge portion (11). ).

The lens (3) has an upper edge for inserting into the embedding groove (12) of the frame (1), and corresponding to the positioning convex portion of the slider (2) outside the lens (3) ( 22) The recess is formed with a positioning recess (31).

In this way, the creation of the present invention is used in operation, please refer to the second diagram of the use state of the creation as shown in the schematic diagram, that is, the upper edge of the lens (3) can be inserted into the frame (1). Inserting into the groove (12), and sliding the slider (2) from the sliding section (13) of the frame (1) toward the lens (3) to make the positioning convex of the slider (2) The portion (22) can be inserted into the positioning recess (31) of the lens (3) so that the lens (3) is indeed positioned in conjunction with the frame (1) without falling off [please refer to the third figure again) The schematic diagram of the three-dimensional combination structure and the fourth diagram of the creation are shown in the schematic cross-sectional structural diagram], and when the user wears the glasses, the outer end of the sliding section (13) of the frame (1) needs to be connected. The pivoting arm (14) is unfolded, so that the temple (14) can have the effect of supporting the slider (2) to prevent the slider (2) from sliding freely, and the lens can be avoided. (3) Produce shedding.

When the lens (3) is to be removed for replacement, only the temple (14) of the frame (1) needs to be folded, and the slider (2) is covered by the sliding segment of the frame (1) (13). Moving upward in the opposite direction of the lens (3), the positioning protrusion (22) of the slider (2) can be separated from the positioning recess (31) of the lens (3), and the The lens (3) is removed by the frame (1) for replacement.

By the above, the composition and use of the creation structure can be seen that, compared with the existing structure, the creation is mainly in the process of assembly, assembly or replacement of the lens, and it is not necessary to prepare a corresponding tool set. It can be more convenient and convenient, and it can also make assembly work faster and complete assembly, and it has more practical and effective features in its overall application.

The above-mentioned embodiments or drawings are not intended to limit the structure of the present invention, and any suitable variations or modifications of those skilled in the art should be considered as not departing from the scope of the invention.

In summary, the present embodiment can achieve the expected use efficiency, and the specific structure disclosed is not only found in similar products, nor has it been disclosed before the application, and has fully complied with the requirements and requirements of the Patent Law.爰Proposing an application for a new type of patent in accordance with the law, and pleading for a review and granting a patent, it is really sensible.
