Specific embodiment
It, below will be to implementation in order to illustrate more clearly of the utility model embodiment or technical solution in the prior art
Attached drawing needed in mode is briefly described.It should be evident that the accompanying drawings in the following description is only that this is practical new
Some embodiments of type for those of ordinary skills without creative efforts, can be with
It obtains other drawings based on these drawings.
When being described for the embodiments of the present invention, term " longitudinal direction ", " transverse direction ", "upper", "lower",
"front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom" "inner", orientation or positional relationship is expressed by "outside"
Based on orientation or positional relationship shown in relevant drawings, it is merely for convenience of describing the present invention and simplifying the description, without
It is that the device of indication or suggestion meaning or element must have a particular orientation, be constructed and operated in a specific orientation, therefore on
Stating term should not be understood as limiting the present invention.
The utility model is described in detail with reference to the accompanying drawings and detailed description, embodiment cannot herein one
One repeats, but therefore the embodiments of the present invention is not defined in following implementation.
Fig. 1 is the diagram for schematically showing eyeglass in the prior art.The state diagram as shown in the figure placed vertically for eyeglass,
As shown, eyeglass includes optical region 1 and non-optical regions 2, non-optical regions 2 are looped around 1 periphery of optical region and optics
Region connection.Non-optical regions 2 include fixed part 21 and coupling part 22.Fixed part 21 is installed in camera lens for eyeglass
Shi Zuowei is born against, and guarantees stability of the eyeglass in camera lens.Coupling part 22 between fixed part 21 and optical region 1,
For connecting optical region 1 and non-optical regions 2.At present since camera shooting product is smaller and smaller for the requirement of camera lens contour structures,
This certainly will cause the structure size of lens also to want smaller and smaller.And eyeglass mostly uses injection molding technology to make, existing eyeglass knot
Structure size become smaller so that eyeglass at the time of molding, cast gate is closer with the effective imaging moiety of eyeglass, and cast gate stress will certainly
It affects to the face type of the effective imaging moiety of lens, because there are stress releases in thermal histories, thus can be right
Lens surface has tension force effect, and then will affect the quality and image quality of lens.
Fig. 2 is the configuration diagram for schematically showing the utility model eyeglass.As shown in Figure 1, Figure 2, the utility model
Eyeglass includes optical region 1 and the non-optical regions 2 around optical region 1.Optical region 2 includes fixed part 21 and interconnecting piece
Divide 22, rough surface structure 3 is equipped on the surface of coupling part 22.The 1 conventional eyeglass non-optical zones in figure can be regarded as
Rough surface structure 3 is provided on the surface of the coupling part 22 in domain 2.Setting rough surface structure 3 makes using injection molding
When technology passes through Mold Making eyeglass, it can effectively reduce stress, because setting surface roughness is equivalent to increase mirror
Runner (necessary channel of the molten plastic from ejaculator nozzle to die cavity) when sheetmolding, runner increase molten when reducing molding
Melt plastics to the cushion effect of eyeglass face type, be also reduced by stress, stress is avoided to impact eyeglass face type, to be conducive to protect
Demonstrate,prove the quality and image quality of the utility model eyeglass.

It sets, coupling part 22 is connect with fixed part 21, and the two angle is zero, and coupling part 22 is considered as prolonging for fixed part 21
It stretches, under such embodiment, step-like structure 4 is likewise arranged on 22 surface of coupling part, can also play same effect
Fruit.
In addition, step-like structure 4 is equipped on the nearly object side and/or nearly image side surface of coupling part 22, in addition to that can subtract
Small stress guarantees to play a protective role to eyeglass except the image quality of eyeglass.Because being provided with step-like structure 4,
When demoulding after lens injection molding, step-like structure 4 can play buffer function, evaded in the prior art eyeglass whole face from mould
It tears in tool and is easy the case where causing damage to eyeglass, i.e., the form demoulded original whole face is converted for multiple small contacts
Emaciated face mould so can improve the qualification rate of eyeglass with effective protection eyeglass.
Fig. 3 is the enlarged drawing for schematically showing step-like structure according to the present utility model.Fig. 4 is to schematically show basis
The size diagram of the step-like structure of the utility model.Black box is not a part of step-like structure 4 in Fig. 4, is only
