Abstract

The utility model relates to a protective film, in particular to a 3D (Three-dimensional) spectacle lens protective film component, which comprises a protective film and a easy-to-tear paste, wherein the protective film consists of a protective layer and a release layer; the easy-to-tear paste comprises a pasting end and a tearing end; a notch is punched in the protective layer; a polygonal traction block of which one side is connected with the protective layer into a whole is formed at the notch; and the pasting end of the easy-to-tear paste is fitted onto the traction block. The 3D spectacle lens protective film component has the beneficial effects that the 3D spectacle lens protective film component has the effect of preventing a lens from being scraped or damaged during the transportation and placement processes; through the design of the position of the notch, the 3D spectacle lens protective film component also has the advantage of convenience in tearing and separating; and in addition, the 3D spectacle lens protective film component is convenient and simple to manufacture and has low cost and high production efficiency.

Description

A kind of 3D lens diaphragm assembly

Technical field

The utility model relates to a kind of diaphragm, is specifically related to a kind of 3D lens diaphragm assembly.

Background technology

In order to prevent in transportation and the put procedure, the 3D eyeglass be subjected to extraneous rub, touch etc. factor to the scratch that causes on the eyeglass, scratch or wearing and tearing etc., before the usefulness of glasses, need to come eyeglass is protected with diaphragm.Because diaphragm belongs to the process materials in the production of 3D glasses and the transportation, need in use it is torn off, and the diaphragm product of 3D eyeglass generally includes protective seam and release layer, in the time of 3D lens pasting protective film, need to remove first release layer.Diaphragm is attached on the eyeglass and certain viscosity is arranged, and generally need to easily tear to paste when using glasses and help tear off.

As shown in Figure 1 and Figure 2; existing 3D lens is positioned at the cut-out direction of the middle diaphragm of diaphragm surface area and the angle at a certain edge of picture frame is 0 degree or 90 degree; when tearing off; more just can tear it down; if this strength is excessive; greater than the cohesive force of easily tearing subsides and diaphragm, can cause again easily tearing the disengaging of subsides and diaphragm and can't arrive the purpose that tears off.

The utility model content

In order to overcome the deficiencies in the prior art, the purpose of this utility model is to provide a kind of 3D lens diaphragm assembly, can not only play the effect of protection eyeglass, and can guarantee easily to tear subsides and tear off convenience, and prevents that protective seam from not torn off.

For addressing the above problem, the technical scheme that the utility model adopts is as follows:

A kind of 3D lens diaphragm assembly; comprise diaphragm and easily tear subsides; diaphragm is comprised of protective seam and release layer; described easily tear to paste comprise the paste-side and to tear end; die-cut on protective seam have an otch; form the polygon guiding piece that a limit and protective seam are integrally connected in incision, the paste-side of easily tearing subsides is fitted on the guiding piece.

Described guiding piece is square or rectangular, and being connected to the extended line on the orthogonal one side, limit on the protective seam and the angle at protective seam edge on the guiding piece with it is α, 40 °≤α≤50 °.

Described easily tear to paste be " L " shape, the lower end that " L " shape is easily torn subsides is the paste-side, the upper end is for tearing end.

The area of described paste-side and the area of guiding piece are complementary.

Compared to existing technology; the beneficial effects of the utility model are: 3D lens diaphragm assembly of the present utility model has the effect that prevents that eyeglass from being scratched or damaging in transportation and put procedure; by the design to incision site, the utility model also has and the advantage such as conveniently tears off.The making side of 3D lens diaphragm assembly of the present utility model is simple in addition, and cost is low, production efficiency is high.

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.

Fig. 2 is the structural representation of the another kind of embodiment of lens diaphragm assembly of prior art;

Fig. 3 is 3D lens diaphragm modular construction schematic diagram of the present utility model;

Fig. 4 is the structural representation of otch described in the utility model and guiding piece.

Embodiment

As shown in Figure 1 and Figure 2; existing 3D lens 1 is positioned at the cut-out direction of the middle diaphragm 2 of diaphragm surface area and the angle at a certain edge of picture frame is 0 degree or 90 degree; when tearing off; more just can tear it down; if this strength is excessive; greater than the cohesive force of easily tearing subsides 3 and diaphragm 2, can cause again easily tearing the disengaging of subsides and diaphragm and can't arrive the purpose that tears off.

As shown in Figure 3, Figure 4; 3D lens diaphragm assembly of the present utility model; comprise diaphragm and easily tear subsides; diaphragm is comprised of protective seam and release layer 2; described easily tear to paste comprise paste-side 5 and to tear end 4; die-cut on protective seam 2 have an otch 6, forms the polygon guiding piece 7 that a limit and protective seam 2 are integrally connected at otch 6 places, and the paste-side of easily tearing subsides is fitted on the guiding piece.This diaphragm assembly in the transportation of 3D lens 1 and process effectively the protective spectacles sheet do not scratched or damaged, during 3D lens 1 pasting protective film, need to remove first release layer, then will be attached on the 3D lens 1 with the diaphragm that easily tears subsides.The 3D glasses pull the end that tears that easily tears subsides in use, are fitted on the guiding piece 7 owing to easily tearing the paste-side 5 of subsides, and guiding piece 7 and protective seam 2 one, thereby can protective seam 2 be torn off lens by the effect of easily tearing subsides and guiding piece.

In the preferred embodiment, guiding piece described in the utility model is square or rectangular, and being connected to the extended line on the orthogonal one side, limit on the protective seam and the angle at protective seam 2 edges on the guiding piece with it is α, 40 °≤α≤50 °.This angle so that the angle at guiding piece and protective seam 2 edges also at 40 °-50 °, is conducive to the stressed of protective seam 2, further facilitate and tear off diaphragm, when wherein this angle is 45 °, tear off effect better, firmly minimum.

For handled easily, in another preferred embodiment, described in the utility model easily tear to paste be " L " shape, the lower end that " L " shape is easily torn subsides is the paste-side, the upper end is for tearing end.

The area of paste-side, easily tears and pastes the complete covered with protective film otch of sticky area and periphery when the area of paste-side is excessive with respect to the area of guiding piece, causes cutting part ineffective, and tearing off of whole diaphragm lost draw; When the area of paste-side is too small, tear easily that to paste viscosity too small, paste and the cutting part disengaging to such an extent as to easily tear, diaphragm does not tear it down.To tear off in order further facilitating, on the basis of above-mentioned any embodiment, to have in the preferred embodiment, the area of described paste-side and the area of guiding piece are complementary.

Above-mentioned embodiment only is preferred implementation of the present utility model; can not limit with this scope of the utility model protection, the variation of any unsubstantiality that those skilled in the art does on basis of the present utility model and replacement all belong to the utility model scope required for protection.
