Description

A kind of polarized lenses

Technical field

The utility model belongs to optical mirror slip technical field, is specifically related to a kind of polarized lenses.

Background technology

Polarized lenses is a kind of the eyeglass allowing the light of a certain particular polarization in natural light to pass, and by its filter action, can make the visual field clear and natural more of people.But existing polarized lenses is arrange one deck light polarizing film at the outside surface of common eyeglass or inside surface mostly, although the polarized lenses structure of this structure is simple, cost is low, but the light polarizing film on polarized lenses is very easily damaged, thus greatly affect the polarization effect of polarized lenses, in addition, because light polarizing film is all be bonded on eyeglass by adhesive glue, therefore also there is the defects such as difficult, the easy slip mutually in location when bonding.

Summary of the invention

For the deficiencies in the prior art, the utility model provides a kind of polarisation diaphragm and not easily damages and the polarized lenses being convenient to bond location.

For achieving the above object, the utility model provides a kind of polarized lenses, comprise eyeglass, lower eyeglass and polarisation diaphragm, described light polarizing film sheet is loaded between on show and lower eyeglass, the edges at two ends place, left and right of described lower eyeglass is evenly equipped with some spherical surface hills, edges at two ends place, the left and right correspondence of described upper eyeglass is provided with the spherical groove that the spherical surface hill for described lower eyeglass embeds, edges at two ends place, the left and right correspondence of described polarisation diaphragm is provided with the pilot hole supplying the spherical surface hill of described lower eyeglass to pass, the left and right end face of described upper eyeglass is also connected with downward eyeglass direction extend and may correspond to formation by polarisation diaphragm and the coated extension block in the inner of lower eyeglass, the lateral surface of described extension block is also equipped with elastic buffer block, and correspondence offers slot on the lateral surface of described extension block, the medial surface of described elastic buffer block is provided with and can forms the grafting projection of grafting secure fit with described slot, the lateral surface of described elastic buffer block is provided with corrugated anti-slip veins.

The beneficial effects of the utility model are: adopt said structure, because polarisation diaphragm of the present utility model is loaded between upper eyeglass and lower eyeglass, therefore effectively can avoid polarisation diaphragm directly and extraneous contact, thus just make polarisation diaphragm not easily damaged.Meanwhile, by the location fit of pilot hole on spherical groove on spherical surface hill on described lower eyeglass and upper eyeglass and polarisation diaphragm, polarized lenses can be made to bond location more easily when bonding, and after bonding, it is interconnected also more solid and reliable.In addition, the setting of described elastic buffer block, can form buffer protection effectively to the two ends, left and right of polarized lenses; The lateral surface of described elastic buffer block arranges corrugated anti-slip veins, effectively can prevent the relative sliding of polarized lenses and picture frame, thus make the connection of polarized lenses and picture frame more reliable and stable.

The utility model can be set to described upper eyeglass and lower eyeglass preferred optics CR39 eyeglass further, and described polarisation diaphragm is preferably by the compound film sheet of TAC lamella, PVA lamella, TAC lamella successively superimposion.Adopt above-mentioned preferred setting, the polarization effect of polarized lenses can be promoted further.

The outside surface that the utility model also can be set to described upper eyeglass further is also provided with monox wearing layer.Adopt said structure, set up monox wearing layer, the outside surface of eyeglass can be made to have more wearing quality, thus greatly extend the whole service life of polarized lenses.

The cross sectional shape that the utility model also can be set to grafting projection on slot and elastic buffer block on described extension block is further swallow-tail form.Adopt said structure, can make the connection of described grafting projection and slot can be more firm.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model;

Fig. 2 is the I portion enlarged drawing of Fig. 1.

Embodiment

As Fig. 1, a kind of polarized lenses is given shown in 2, comprise eyeglass 1, lower eyeglass 2 and polarisation diaphragm 3, described polarisation diaphragm 3 is loaded between eyeglass 1 and lower eyeglass 2, the edges at two ends place, left and right of described lower eyeglass 2 is evenly equipped with some spherical surface hills 21, edges at two ends place, the left and right correspondence of described upper eyeglass 1 is provided with the spherical groove 11 that the spherical surface hill 21 for described lower eyeglass 2 embeds, edges at two ends place, the left and right correspondence of described polarisation diaphragm 3 is provided with the pilot hole 31 supplying the spherical surface hill 21 of described lower eyeglass 2 to pass, the left and right end face of described upper eyeglass 1 is also connected with downward eyeglass 2 direction extend and may correspond to formation by polarisation diaphragm 3 and the coated extension block 12 in the inner of lower eyeglass 2, the lateral surface of described extension block 12 is also equipped with elastic buffer block 4, and correspondence offers slot 121 on the lateral surface of described extension block 12, the medial surface of described elastic buffer block 4 is provided with and can forms the grafting projection 41 of grafting secure fit with described slot 121, and on described extension block 12 on slot 121 and elastic buffer block 4 cross sectional shape of grafting projection 41 be swallow-tail form, the lateral surface of described elastic buffer block 4 is provided with corrugated anti-slip veins 42.The outside surface of described upper eyeglass 1 is also provided with monox wearing layer 5.Described upper eyeglass 1 and lower eyeglass 2 preferably optics CR39 eyeglass, described polarisation diaphragm 3 is preferably by the compound film sheet of TAC lamella, PVA lamella, TAC lamella successively superimposion.

Adopt said structure, because polarisation diaphragm 3 of the present utility model is loaded between upper eyeglass 1 and lower eyeglass 2, therefore effectively can avoid polarisation diaphragm 3 directly and extraneous contact, thus just make polarisation diaphragm 3 not easily damaged.Meanwhile, by the location fit of spherical surface hill on described lower eyeglass 2 21 with pilot hole 31 on spherical groove 11 on upper eyeglass 1 and polarisation diaphragm 3, polarized lenses 3 can be made to bond location more easily when bonding, and after bonding, it is interconnected also more solid and reliable.In addition, the setting of described elastic buffer block 4, can form buffer protection effectively to the two ends, left and right of polarized lenses 3; The lateral surface of described elastic buffer block 4 arranges corrugated anti-slip veins 42, effectively can prevent the relative sliding of polarized lenses 3 and picture frame, thus make the connection of polarized lenses 3 and picture frame more reliable and stable.
