Description

A kind of change type glasses

Technical field

What the utility model related to that a kind of improvement invention of glasses is particularly related to is a kind of improvement invention that can accept or reject the spectacle frame structure of changing eyeglass rapidly.

Background technology

In the prior art, glasses are formed by mirror holder and eyeglass, no matter be near-sighted glasses, presbyopic glasses or sunglasses, want to use instead, must carry to overpay to have independent functional eyeglasses, particularly travel on official business, and are very inconvenient.

Summary of the invention

In view of the problem that known technology exists, the purpose of this utility model aim to provide a kind of on same mirror holder the mirror holder and the lens structure of translation function eyeglass rapidly, under different occasions, select to change the needs that use eyeglass fast to satisfy the user.

The utility model is finished as follows: this reversible type glasses, include picture frame, ear frame, nose holder and eyeglass, be primarily characterized in that described nose holder support is provided with the pin of band back-moving spring, side at described picture frame is provided with the snap-lock bar that ribbon gymnastics is made handle, this securing rod becomes to be dynamically connected with the picture frame bolt, described picture frame bolt is provided with torsion spring, but the moving operating grip of plate makes the snap-lock bar carry out displacement when eyeglass is changed, and the both sides of described eyeglass are provided with the draw-in groove that is complementary with pin and snap-lock bar.The snap-lock bar that ribbon gymnastics is made handle on band pin of back-moving spring and the picture frame on the described nose holder support is symmetrical arranged on the picture frame of the left and right sides.

The utility model is compared with known technology, have simple in structure, reasonable in design, can be according to the service condition of different occasions, change eyeglass no matter be the myopia that youth, old age, sir, Ms can select and change fast the different number of degrees according to the needs of oneself for use fast, presbyopic or sunglasses, according to the change type glasses of the utility model design motif made, will vast glasses user bring positive result of use.

Specific embodiment

Accompanying drawing has been represented structure of the present utility model and embodiment, further describe each relevant details of embodiment below more in conjunction with the accompanying drawings, this reversible type glasses, mainly by picture frame 1, ear frame 2, assemblies such as nose holder 3 and eyeglass 8 are formed, its main innovation partly be on nose holder 3 supports 12 be provided with the band back-moving spring 4 pin 5, the gap that this pin 5 is provided with spring base and can holds two overlapping lens thicknesses at least, be provided with ribbon gymnastics in the both sides of described picture frame 1 and make the snap-lock bar 6 of handle 11, this snap-lock bar 6 is dynamically connected for 7 one-tenth with the picture frame bolt, described picture frame bolt 7 is provided with torsion spring 10, can pull operating grip 11 when changing eyeglass 8 is shifted snap-lock bar 6, so that the snap-lock bar fixed or broken away from eyeglass, the both sides of described eyeglass 8 are provided with respectively the draw-in groove 9 that is complementary with pin 5 and snap-lock bar 6, and the snap-lock bar that ribbon gymnastics is made handle on the pin of band spring and the picture frame on the support 12 of described nose holder 3 is symmetrical set on picture frame.

When the user wears near-sighted glasses at ordinary times, in the way of travelling on official business, need to avoid high light to stimulate, when increasing sunglasses, as long as the user takes out the eyeglass with structure of the present utility model, the pin of band spring on original spectacles nose holder support up one is pushed up, this pin just manifests the gap of lens thickness under the compressing of spring, at this moment, the user snaps in pin with the draw-in groove of eyeglass one side, spring reset after the lens orientation, is pulled the snap-lock bar spanner on the picture frame again, allow securing rod leave the draw-in groove of former eyeglass, and the snap-lock bar is entered simultaneously in the draw-in groove of former eyeglass and newly-increased sunglasses, owing to also be provided with back-moving spring on the picture frame bolt, so this eyeglass will firmly be fixed on the picture frame and can not come off, the installation method of left and right sides eyeglass is identical, and is very simple and convenient.According to the change type glasses of the utility model design motif made, no matter be correcting lens, functional lens, or protection glass, all can adjust use at any time.
