Abstract

The utility model provides a presbyopic glass block, including the substrate, and locate the wearing layer at this substrate edge, this wearing layer includes wear -resisting basal portion, and with the perpendicular buckling parts of being connected of this basal portion, this buckling parts be " L " style of calligraphy, the extension is located to the center of this wear -resisting basal portion to this buckling parts, and this buckling parts and the formation of this a wear -resisting basal portion lock groove, this wearing layer is connected with this substrate through this lock groove. Because the edge of this substrate is equipped with this wearing layer, so can protect this presbyopic glass block's edge, prolong this presbyopic glass block's life.

Description

Presbyopic glass block

Technical field

This utility model relates to optometric technology field, particularly to a kind of presbyopic glass block.

Background technology

After people a to dating, the crystalline lens of human eye can gradually fibrosclerosis, ciliary muscle can gradually fiber crops Numbness, makes human eye cannot effectively regulate the shape of eyeball, can only by the distance of regulation eyes and regarded object, Just can see regarding object, this normal physiological phenomenon is referred to as presbyopia, and the generation of reading glasses is proper Solve well this problem, have after presbyopic people puts on reading glasses, eyes and regarded thing need not be regulated The distance of body, it is possible to directly see clearly regarding object.

Some reading glasses without picture frame occur in the market, or the picture frame of some reading glasses is general only Wrap up the part at presbyopic glass block edge and all edges of presbyopic glass block are not protected, when making When presbyopic glass block is dropped to the ground by user's imprudence, the edge of presbyopic glass block easily damages, thus affects The service life of presbyopic glass block.

Utility model content

Based on this, the purpose of this utility model is to provide a kind of presbyopic glass block to edge with safeguard function.

A kind of presbyopic glass block, including substrate, and is located at the wearing layer of this substrate edge, and this wearing layer includes Abrasion-resistant base, and buckling parts connected vertically with this abrasion-resistant base, this buckling parts is "L" shaped, this fastening Portion extends to the center of this abrasion-resistant base, and this buckling parts forms a buckling groove with this abrasion-resistant base, and this is resistance to Mill layer is connected with this substrate by this buckling groove.

Further, this wearing layer is circular ring structure, and this wearing layer uses elastomeric material to make.

Further, this substrate includes middle part, the end being connected with in the middle part of this, is connected with this end Connecting portion, and the lock part being connected with this connecting portion.

Further, the thickness of this connecting portion is less than the thickness of this lock part, and the thickness of this lock part is less than being somebody's turn to do The thickness of end, and this connecting portion, this lock part and this end form a short slot.

Further, this lock part is located in this buckling groove, and this buckling parts fits with this short slot.

Further, this substrate is aspherical lens, this substrate in the middle part of this to this end, radius of curvature by Cumulative add.

Above-mentioned presbyopic glass block, owing to the edge of this substrate is provided with this wearing layer, it is possible to this presbyopia The edge of eyeglass protects, and extends the service life of this presbyopic glass block.

Accompanying drawing explanation

Fig. 1 is the axonometric chart of a kind of presbyopic glass block in this utility model first embodiment.

Fig. 2 is the decomposing schematic representation of the cross section of presbyopic glass block in Fig. 1.

Detailed description of the invention

For the ease of understanding this utility model, below with reference to relevant drawings, this utility model is carried out more comprehensively Description.Accompanying drawing gives some embodiments of the present utility model.But, this utility model can be to be permitted The most different forms realizes, however it is not limited to embodiment described herein.On the contrary, provide these to implement The purpose of example is to make to disclosure of the present utility model more thoroughly comprehensively.

It should be noted that when element is referred to as " being fixedly arranged on " another element, and it can be directly at another yuan On part or element placed in the middle can also be there is.When an element is considered as " connection " another element, and it can To be directly to another element or to may be simultaneously present centering elements.Term as used herein " is hung down Straight ", " level ", "left", "right" and similar statement for illustrative purposes only.

Unless otherwise defined, all of technology used herein and scientific terminology with belong to of the present utility model The implication that those skilled in the art are generally understood that is identical.Institute in description of the present utility model herein The term used is intended merely to describe the purpose of specific embodiment, it is not intended that in limiting this utility model. Term as used herein " and/or " include the arbitrary and all of of one or more relevant Listed Items Combination.

Refer to Fig. 1 and Fig. 2, a kind of presbyopic glass block provided in first embodiment in this utility model, bag Include substrate 10, and be located at the wearing layer 11 at this substrate 10 edge.

This wearing layer 11 is circular ring structure, and this wearing layer 11 uses elastomeric material to make.This wearing layer 11 wraps Include abrasion-resistant base 111, and with this abrasion-resistant base 111 buckling parts connected vertically 112.This buckling parts 112 is "L" shaped, this buckling parts 112 extends to the center of this abrasion-resistant base 111, and this buckling parts 112 with This abrasion-resistant base 111 forms a buckling groove 113.

This substrate 10 includes middle part 101, and the end 102 being connected with in the middle part of this 101, with this end 102 The connecting portion 103 being connected, and the lock part 104 being connected with this connecting portion 103.This connecting portion 103 Thickness is less than the thickness of this end 102 less than the thickness of this lock part 104, the thickness of this lock part 104, And this connecting portion 103, this lock part 104 form a short slot 105 with this end 102.This lock part 104 sets In this buckling groove 113, this buckling parts 112 fits with this short slot 105.This substrate 10 is aspherical mirror Sheet, this substrate 10 is 101 to this end 102 in the middle part of this, and radius of curvature is gradually increased.

To sum up, in this utility model above-described embodiment, owing to the edge of this substrate 10 is provided with this wearing layer 11, So the edge of this presbyopic glass block can be protected, extend the service life of this presbyopic glass block.

Embodiment described above only have expressed certain embodiment of the present utility model, its describe more concrete and In detail, but therefore can not be interpreted as the restriction to this utility model the scope of the claims.It should be pointed out that, For the person of ordinary skill of the art, without departing from the concept of the premise utility, it is also possible to Making some deformation and improvement, these broadly fall into protection domain of the present utility model.Therefore, this utility model The protection domain of patent should be as the criterion with claims.
