Description
Technical field
The utility model belongs to optometric technology field, and in particular to a kind of glasses suitable for 3D printing.
Background technique
Nose support is the component that spectacle frame plays a supportive role on the bridge of the nose, is support construction of the spectacle frame on the bridge of the nose, to
Holding glasses wearer's is comfortable, and the feature of nose support and user's bridge of the nose is consistent.Nose support in the prior art has two classes, and one kind is solid
Sizing, such nose support mostly use greatly plastic or other material, or integrated molding Nian Jie with spectacle frame, referring to fig. 1.However, this
The bridge of the nose higher crowd of the class nose support often appropriate only to user.
Another kind of is stipule active type, and the nose support of this type is applied to metal frame mostly, and nose support is made of two parts, one
For stipule part, one must part for nose, wherein stipule part is made of stipule and nose support retainer plate, nose support retainer plate by means of
Substrate is embedded and is fixed in stipule, in use, the end face of stipule is contacted with the bridge of the nose, thus by mirror support supports on the bridge of the nose.Nose
It must be also to be made of two parts, one is support stalk, and one is stake box, and support stalk is the interconnecting piece of mirror holder ontology (Jing Quan or beam) and stake box,
Stake box is the component for accommodating, fixing nose support retainer plate.Stipule and nose must be configured to an entirety by means of screw, certain glasses
This is integrated with a lesser adjustment space, can including nose support height, stipule angle and stipule and the relative position of mirror holder etc.
To make nose support adapt to the feature of user's bridge of the nose to a certain extent.But the adjusting range of such nose support is very limited.It is existing
In technology, when nose must be connect with spectacle frame, in order to reduce production cost, simplify production technology, usually in nose palpus and glasses
One connecting portion is only set between frame, that is, nose must be fixed in the wire-shaped of bending, end and the mirror holder of wire.By
Metal material is used in such nose support, the mechanical strength of nose palpus is also easy to reach in the case where only passing through a connecting portion connection
To professional standard, however new problem is but caused using metal material, that is, nose support, which is easy to issue in erosions such as sweat stains, gets rusty
Erosion, influences service life.
Nose support and mirror holder used in the prior art are made usually using metal, plastics, resin or mixing material, system
It is more traditional to make technique, e.g., using plastic material injection molding etc..In recent years, a kind of 3D printing technique is newly risen.So-called 3D
Printing technique, refer to one kind based on digital model file, with powdered adhesive material, by layer-by-layer printing
To manufacture the technology of object.3D printing generallys use digital technology file printing machine to realize, used material generally includes
Nylon, aluminum material, gold-plated, silver-plated, rubber etc..Its print procedure is general are as follows: first passes through computer modeling software modeling, then will build
At threedimensional model " subregion " at layer-by-layer section, that is, be sliced, so that printer be instructed successively to print.Currently, 3D printing technique
Certain achievement is had been achieved in the geometry and function for rebuilding object, the shape of substantially any static state can be beaten
It prints off and, be applied to glasses manufacturing for it and provide possibility.But limited by machine in the prior art, by its
Problem for causing new when actual production is to be resolved, be such as difficult to realize the object printed mechanical strength with higher,
The rough object surfaces etc. printed.
Utility model content
The purpose of this utility model is to provide a kind of glasses suitable for 3D printing, makes it easy to raw by 3D printing technique
While producing manufacture, and the defect of the above-mentioned prior art can be overcome, reach requirement of the Glasses structure to mechanical strength, especially
Nose piece portion for support glasses is not easy to break, fractures.
In order to achieve the above object, the technical solution of the utility model is as follows:
A kind of glasses suitable for 3D printing, including nose support and glasses frame body, the nose support and spectacle frame body by integral forming, institute
Stating nose support includes nose support retainer plate, the first nose palpus and the second nose palpus；One end and glasses frame body of first nose palpus and the second nose palpus connect
It connects, so that the nose support be made to be connected and fixed with glasses frame body, the other end of the first nose palpus and the second nose palpus is fixed with nose support respectively
Circle connection, the first nose palpus, the second nose palpus, nose support retainer plate and glasses frame body surround the first hollow framework.
Glasses structure provided by the utility model has the following beneficial effects:
1, when being manufactured using 3D printing technique, the glasses of the utility model use frame structure, are easy to model, and can be with
The space angle of nose support is adjusted according to the bridge of the nose feature of different users, it must be with the second nose palpus by the first nose of strip
Appropriate curling or bending, adjustment length, can be adjusted the relative position of nose support Yu glasses frame body, and then unrestricted choice nose holder is put
In on some position of face, and when adjusting user's wearing spectacles at a distance from mirror holder and face, thus for nose support personalization
Customization offer is possible, and the structural parameters of glasses is made to meet the facial characteristics of user, thus more comfortable when wearing, therefore,
The Glasses structure of the utility model is conducive to customization of individual character, batch production；
2, it must be connect with glasses frame body due to nose support using more than one nose, 3D printing skill in the prior art can be overcome
