背景技术Background technique

With the continuous improvement of people's living standards, people's demand for quality of life is also changing. Glasses are no longer the items that people need because of eye correction. It has become a daily decoration for people, and its various transformations. The shape and color are matched according to the needs of clothing or personality. Whether it is sunglasses, or far-sighted, myopia correction glasses will be equipped with multiple pairs of casual matching needs, which invisibly increases the cost of glasses. Therefore, there is a combination of the frame and the lens that can be replaced, and the lens shape is changed flexibly.

However, at present, the lenses of the lens can be replaced, and the frame is mostly a plastic frame, which utilizes the deformable characteristics of the plastic frame to realize the disassembly and replacement of the lens. The metal frame with texture cannot realize the function of flexible lens replacement, and it must be replaced by tools, which is limited by the material properties of the metal frame without deformation. How to make the metal frame glasses can also realize the flexibility and randomness of the lens and the frame change, which is a problem to be solved by the present invention.

Forming a matching groove to receive the upper edge of the lens; wherein: the frame is provided with a matching hole for the positioning mechanism, the matching hole communicates with the matching groove; and the positioning mechanism includes a connecting screw seat and is placed in the connection The spring in the screw seat and the chuck, the positioning mechanism is matched in the matching hole, and the chuck is elastically extended in the matching groove; and the countertop is provided with a counterbore or a through hole which cooperates with the positioning mechanism chuck.

The two sides of the frame nose piece are laterally provided with a groove, and the upper side of the lens is provided with a matching protrusion on the groove.

The matching hole is arranged in the frame of the proximal connecting portion of the matching groove, and the matching hole is vertically connected to the side wall of the matching groove, and the other end of the matching hole is penetrated through the inner wall surface of the frame, and the connection of the matching hole and the matching groove A necking hole is formed at the portion, and an internal thread is provided in the fitting hole.

The connecting screw seat is externally provided with an external thread, a cavity is arranged in the middle to accommodate the spring and the chuck, and a bottom for the opening operation is provided at the bottom of the connecting screw.

The front end of the chuck forms a circular arc head, and the outer diameter of the circular arc head is smaller than the inner diameter of the neck narrowing hole, and the rear end of the chuck head forms a flange whose outer diameter is larger than the neck narrowing hole.

After adopting the above solution, the present invention provides an elastic positioning mechanism in the matching groove of the frame and the lens, and at the same time, the positioning mechanism is provided with a counterbore or a through hole on the lens, so that the lens can be flexible through the positioning mechanism. Fit or disengage from the frame to achieve the flexibility of the metal frame without the need for tools to flexibly change lenses.

具体实施方式detailed description

As shown in FIG. 1 to FIG. 8 , a movable combination spectacles according to the present invention includes a temple (not shown), a metal frame 1 and a lens 2 , and the frame 1 is further provided with a positioning mechanism for cooperating with the lens 2 . 3.

The metal frame 1 is a frame having only an upper frame, the middle of the frame is a nose pad portion 11, the two ends of the frame are the connecting portions of the temples, and the frame between the nose pad portion 11 and the connecting portion is formed from the bottom to the top. The groove 12 is engaged to receive the upper edge of the lens 2; the groove 13 is laterally disposed on both sides of the nose pad portion 11; and the fitting hole 14 for the positioning mechanism 3 is respectively disposed in the frame of the proximal connection portion of the fitting groove 12 The matching hole 14 is vertically connected to the side wall of the engaging groove 12, and the other end of the matching hole 14 is penetrated through the inner wall surface of the frame 1. The connecting hole 14 and the engaging groove 12 form a necking hole 141, and An internal thread 142 is provided in the fitting hole 14.

The two ends of the lens 2 are provided with a matching portion with the lens frame 1 , wherein a matching portion is a matching protrusion 21 corresponding to the groove 13 , and another engaging portion is disposed at a position corresponding to the matching hole 14 of the lens 2 . Counterbore 22 or through hole.

The positioning mechanism 3 includes a connecting screw 31, a spring 32 and a chuck 33. The connecting screw 31 is externally provided with an external thread 311 which cooperates with the internal thread 142, and a cavity 312 is disposed in the middle to accommodate the spring 32. And a chuck 33, and a recess 313 for opening operation is further disposed at the bottom of the connecting screw 31; the front end of the chuck 33 forms a circular arc head 331, and the outer diameter of the circular arc head 331 is smaller than the inner diameter of the necking hole 141, and the chuck head The rear end of the 33 forms a flange 332 having an outer diameter larger than the neck hole 141. When assembled, the spring 32 and the chuck 33 are sequentially placed in the cavities 312 of the connecting screw 31, and then the screw base 31 is screwed into the mating hole 14 of the frame 1 again, and the chuck 33 is held under the spring 32. The necking hole 141 protrudes from the fitting groove 12, and the positioning mechanism 3 at this time is an elastic locking structure.

When the lens 2 is combined with the lens frame 1, the protrusions 21 of the two lenses 2 are first inserted into the grooves 13 of the nose pad portion 11 of the frame 1 and then rotated in the mating slots 12 of the pivot frame 1 . When the upper side of the lens 2 is completely placed in the mating groove 12, the elastic chuck 33 of the positioning mechanism 3 is just inserted into the counterbore 22 of the lens 2, so that the lens 2 achieves a firm fit with the frame 1.

When the replacement of the lens 2 and the lens frame 1 is required, the opposite side of the counterbore 22 of the lens 2 is first applied, and the counterbore 22 of the lens 2 is disengaged from the engagement with the chuck 33 of the positioning mechanism 3, and vice versa. The protrusion 21 of the lens 2 is pulled out from the groove 13 of the nose pad portion 11 of the lens frame 1, and the disassembly operation of the lens 2 and the lens frame 1 is completed. According to the above combined action, the free combination of the lens 2 and the lens frame 1 is realized by replacing other lenses.

In summary, the present invention provides an elastic positioning mechanism 3 in the mating groove 12 of the frame 1 and the lens 2, and at the same time, the positioning mechanism 3 is provided with a counterbore 22 or a through hole on the lens 2 so that the lens 2 is made. The positioning mechanism 3 can be flexibly engaged or disengaged from the frame 1 to realize the effect of the metal frame 1 being flexibly replaced without the need for tools. Of course, the structure is also applicable to plastic frames.
