The lens that hides contracting sight line of the present invention has following technique effect: it comprises eyeglass main body and light shielding part, and in the ordinary course of things, the lens of eyeglass main body and other hidden contracting sight line is as broad as long, can normally use; But when people are when working, learning or reading, can, by light shielding part is set, by sight line blocking, people's the visual field be confined to, in a less region at the moment, make people more absorbed.
Accompanying drawing explanation
Fig. 1 is that lens of the present invention is installed in a structural representation in eyeglasses frame;
Fig. 2 is the A-A cross section view of Fig. 1;
Fig. 3 is the B-B cross section view of Fig. 1, is the structural representation of the connecting portion of first and second portion.
Embodiment
Below in conjunction with accompanying drawing, the present invention is described in further detail, to make those skilled in the art can implement according to this with reference to instructions word.
As shown in Figure 1, Figure 2 and Figure 3, the invention provides a kind of lens that hides contracting sight line, comprising: eyeglass main body 1, its periphery has annular protrusion 6, light shielding part, it comprises first 2 and second portion 7, the inwall of described first is formed with the first groove 5, the inwall of described second portion 7 is formed with the second groove 8, the two ends of described first 2 are extended with respectively a plug connector 9 downwards, two outer walls of each plug connector 9 form respectively a depression 12, the two ends of described second portion 7 are formed with respectively the groove being limited out by a pair of card 10, the inwall of each card is formed with outstanding fastening part 11, and described fastening part 11 is positioned at the first half 13 of described groove, wherein, described first is arranged at the top of described eyeglass main body 1, a part for described annular protrusion is inserted in described the first groove 5, described second portion is arranged at the bottom of described eyeglass main body, another part of described annular protrusion is inserted in described the second groove 8, and described plug connector is inserted into the first half 13 of described groove, described fastening part 11 is equipped in described depression 12, thereby make described first and described second portion be connected to each other to a cylindrical part that is located on described eyeglass main body outside, the rear end face 16 of described cylindrical part is substantially concordant with the rear end face 17 of described eyeglass main body, the latter half 14 of described groove is for passing for mirror holder.
Eyeglass main body can adopt existing concave lens, and in the situation that light shielding part not being set, eyeglass main body can directly be used as near-sighted glasses.But when people want to be absorbed at the moment, can be by means of light shielding part reduced field of view.
Light shielding part comprises first 2 and second portion 7, the inwall of first 2 is formed with the first groove 5, the inwall of second portion 7 is formed with the second groove 8, the periphery of eyeglass main body has annular protrusion 6, when light shielding part is located on the outside of eyeglass main body, annular protrusion snaps in the first groove and the second groove, so that the directly stable connection of light shielding part and eyeglass main body.
Two ends of first and second portion are connected into a complete cylindrical part each other.Specifically, the two ends of first are extended with respectively a plug connector 9 downwards, the outer wall of each plug connector forms the depression 12 of bar shaped, the two ends of second portion are formed with respectively a groove, groove is formed toward each other by a pair of card 10, groove is divided into the first half 13 and the latter half 14, and the inwall of each card has the fastening part 11 of outstanding bar shaped.When a plug connector 9 being inserted into the first half 13 of a groove, a pair of fastening part is just in time positioned at a pair of depression, so just plug connector is fixed to the first half at groove, thereby first and second portion are linked together.
Eyeglass main body 1 is arranged on mirror holder, therefore, will be when light shielding part being installed in eyeglass main body, respectively first is arranged on to the top of eyeglass main body, second portion is arranged on to the bottom of eyeglass main body, mirror leg 1, through the latter half of a groove, is arranged on 4 the latter halfs through another groove of two web members between eyeglass main body.
In the lens of described hidden contracting sight line, described light shielding part is provided with light intensity sensor and alarm lamp, described light intensity sensor and described alarm lamp are electrically connected to, and when described light intensity sensor detects environmental light intensity signal lower than setting threshold, described light intensity sensor drives described alarm lamp flicker.
When insufficient light, should not use light shielding part.Now miniature light intensity sensor and alarm lamp can be set on light shielding part, when the environmental light intensity that detects when light intensity sensor is not enough, by alarm lamp flicker, be reported to the police.
In the lens of described hidden contracting sight line, the thickness of described light shielding part is 3～4 times of described eyeglass body thickness.In order to obtain better blocking sight line, light shielding part need to have certain thickness and width.
In the lens of described hidden contracting sight line, the width of described light shielding part is 0.5～1mm.
In the lens of described hidden contracting sight line, described light shielding part is for to be made by lighttight plastics.
In the lens of described hidden contracting sight line, one section of described light shielding part is the transparent section of being made by transparent material, and the remainder of described light shielding part is that lighttight material is made.In order not affect the thing of looking at the moment, light shielding part is arranged to printing opacity near a part 15 for nose support, other part adopts lighttight plastics.
Although embodiment of the present invention are open as above, but it is not restricted to listed utilization in instructions and embodiment, it can be applied to various applicable the field of the invention completely, for those skilled in the art, can easily realize other modification, therefore do not deviating under the universal that claim and equivalency range limit, the present invention is not limited to specific details and illustrates here and the legend of describing.
