Description

Anti-drop polarized lens

Technical Field

The utility model relates to the field of polarized lenses, in particular to an anti-falling polarized lens.

Background

A polarized lens is a lens that allows only light of a certain polarization direction among natural light to pass through. It darkens when worn due to its filtering effect. To filter the glare of the sun in the equal direction on water, land or snow, a special vertical coating is added to the lens, called polarized lens.

Most of the existing polarized lenses are used outdoors, the damage probability is high, and when the polarized lenses are used outdoors, if the lenses are damaged or fall off, new lenses are difficult to replace at one time and a half of the lenses are difficult to replace, so that the fall-off prevention and damage prevention of the lenses are important.

Disclosure of Invention

Aiming at the problems in the prior art, the utility model aims to provide an anti-falling polarized lens for solving the problems in the background art.

In order to achieve the above purpose, the present utility model provides the following technical solutions: the utility model provides an anti-drop polarized lens, includes lens frame, lens and screw, lens frame inner wall joint has the lens, and lens frame and lens are fixed through the screw.

As a further scheme of the utility model: the lens comprises an inner lens, an outer lens, a limiting groove and screw holes, wherein one side of the inner lens is fixed with the outer lens through glue, the outer lens is provided with two groups of symmetrically arranged on two sides of the inner lens, the edge of the outer lens is in an inward concave state, the edge of the outer lens is provided with the limiting groove, one side of the inner lens is provided with the screw holes, and the screw holes are provided with two groups of symmetrically arranged on two sides of the inner lens.

As a further scheme of the utility model: the same openings are formed in the positions, corresponding to the screw holes of the inner layer lenses, of the side walls of the outer lens frames.

As a further scheme of the utility model: the inner wall of the lens outer frame is provided with a bulge corresponding to the limit groove of the outer layer lens.

Compared with the prior art, the utility model has the beneficial effects that:

this anti-drop polarized lens, including lens frame, lens and screw, lens frame inner wall joint has the lens, and lens frame and lens pass through the screw and fix, when using, lens frame and lens are the structure of mutual chucking, consequently can not appear the lens pine to take off the condition that drops, utilizes the screw to further play reinforced action, compares more fastening in the fixed mode of outer hoop in the past.

Drawings

FIG. 1 is a schematic view of an anti-drop polarized lens according to the present utility model;

fig. 2 is a top view of the anti-drop polarized lens of the present utility model.

As shown in the figure: 1. a lens outer frame; 2. a lens; 3. a screw; 4. an inner lens; 5. an outer layer lens; 6. a limit groove; 7. screw holes.

Detailed Description

The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model.

Referring to fig. 1-2, in the embodiment of the utility model, an anti-falling polarized lens comprises a lens frame 1, a lens 2 and a screw 3, wherein the lens 2 is clamped on the inner wall of the lens frame 1, the lens frame 1 and the lens 2 are fixed by the screw 3, and when the anti-falling polarized lens is used, the lens frame 1 and the lens 2 are of a mutually clamped structure, so that the situation that the lens 2 is loosened and falls does not occur, the screw 3 is utilized to further play a reinforcing role, and the anti-falling polarized lens is more fastened compared with the traditional external hoop type fixing mode.

The lens 2 includes inlayer lens 4, outer lens 5, spacing recess 6 and screw hole 7, inlayer lens 4 one side is fixed through glue with outer lens 5, outer lens 5 is equipped with two sets of and symmetry setting in inlayer lens 4 both sides, outer lens 5 edge is the indent state, spacing recess 6 has been seted up at outer lens 5 edge, screw hole 7 has been seted up to inlayer lens 4 one side, two sets of and symmetry setting in inlayer lens 4 both sides have been seted up to screw hole 7, the state of outer lens 5 edge recess makes when the installation, be convenient for more slide into in the lens frame 1, the resistance of installation is less than the smooth lens in edge in the past, three-layer lens design can play the guard action, even appear the broken condition of outer lens 5, also can not influence the continuation use of inlayer lens 4.

The same trompil has been seted up to the screw hole 7 department that lens frame 1 lateral wall corresponds inlayer lens 4, lens frame 1 inner wall corresponds spacing recess 6 department of outer lens 5 and is equipped with the arch, and when installing, the inside protruding chucking of lens frame 1 realizes fixing between outer lens 5 and the lens frame 1 in spacing recess 6 of outer lens 5, in the trompil of screw hole 7 and lens frame 1 lateral wall of screwing in inlayer lens 4 again this moment, realizes fixing between inlayer lens 4 and the lens frame 1, and owing to be the design of layering, even outer lens 5 breakage drops, utilizes the inlayer lens 4 of screw 3 fixation also can not receive the influence.
