Abstract

The utility model discloses an adjustable spectacle bridge pad which is arranged in the middle of two frames. The upper part of the spectacle bridge pad is connected with a spectacle bridge, and the lower part of the spectacle bridge pad is provided with a nose pad. The utility model is characterized in that: an elastic adjusting component arranged inside the spectacle bridge pad is connected with the nose pad; and the elastic adjusting component comprises a fixed block, an elastic piece and a pressing block. The adjustable spectacle bridge pad can perform elastic adjustment through the elastic adjusting component. Regarding different wearing statuses (mainly referring to the different distances between the spectacle bridge and the nose bridge of a user), the product can perform automatic flexible position adjustment to maintain a proper pressing force, thereby effectively solving the problem that the prior spectacles with a single pad are difficult to adapt to different users and different utilization statuses of the same user, and bringing about simpler, safer and more comfortable use. In addition, the product which can be conveniently applicable to the prior spectacle forms can also be applied to the reconstruction of the prior spectacles with a wider application range.

Description

A kind of adjustable glasses central sill stipule

Technical field

The utility model relates to a kind of spectacle frame structure, particularly a kind of adjustable glasses central sill stipule.

Background technology

The double bracket leaf is adopted in the nose holder of common spectacles frame at present more, they are arranged on the central sill both sides of spectacle frame respectively by two cramp bars, though this double bracket leaf spectacle frame is for a long time popular, most users are accustomed to, but still have some shortcomings, the easy stress deformation of cramp bar as the double bracket leaf of existing spectacle frame, cause the spacing of two stipules to strengthen, thereby make spectacle frame easily in bridge of the nose slide down, influence sight line, this in addition double bracket leaf spectacle frame relies on the double bracket leaf to be installed in bridge of the nose both sides and supports, if the bridge of the nose is short, this spectacle frame just can't support, thereby also inapplicable to the short people of the bridge of the nose.In order to overcome these problems, a kind of single mount leaf spectacle frame is disclosed in the patent No. is 200520025665.4 Chinese utility model patent, this single mount leaf spectacle frame is made up of leg of spectacles hinged outside the spectacle-frame of two installation lenses, the intermediate beam that connects two spectacle-frames, two spectacle-frames and the nose holder that is installed on the spectacle frame, described nose holder is the cramp bar that one one end is packed in spectacle-frame intermediate beam central authorities, and the other end of cramp bar is equipped with the nose stipule; Described nose stipule can be circular arc or V-arrangement.Similarly, in the patent No. is 200520050061.5 Chinese utility model patent a kind of spectacle frame that adopts whole monolithic stipule is also disclosed.These two kinds of spectacle frames have all changed existing double bracket impeller structure form and have adopted the single mount impeller structure, the stipule spacing that can overcome double bracket leaf glasses changes easily, the problem that glasses are glided easily, but all have a tangible problem: stipule is difficult to be adjusted, can not adjust the position at any time with the user mode of user's variation, with the person's of being used use.So this single mount leaf glasses only on the bridge of the nose a certain position wear properly, change slightly as the position and then can not normally use.

The utility model content

The shortcoming that the purpose of this utility model is to overcome prior art provides a kind of rational in infrastructure with not enough, is easy to adjust, and can adapt to the adjustable glasses central sill stipule of the different user modes of different users and same user automatically.

The purpose of this utility model is achieved through the following technical solutions: a kind of adjustable glasses central sill stipule, be arranged in the middle of glasses two picture frames, its top is connected with the glasses central sill, its underpart is equipped with the nose stipule, it is characterized in that: inside is provided with the flexible adjustment assembly, and described flexible adjustment assembly is connected with the nose stipule.

Described flexible adjustment assembly comprises fixed block, elastic component, briquetting, described fixed block is fixedlyed connected with the glasses central sill, described briquetting and nose stipule one end are hinged, described fixed block is connected with briquetting, between fixed block and briquetting, be provided with elastic component, described elastic component one end and fixed block be apical grafting mutually, and the other end and nose stipule one end be apical grafting mutually.

Described fixed block and glasses central sill can be bonding connection, chimericly are connected, welding or by modes such as screw are connected.

Described fixed block is connected by screw with briquetting.

Described briquetting is provided with groove, described groove walls is provided with through hole, and nose stipule one end is provided with projection, and described projection stretches in the groove, projection at nose stipule one end also is provided with through hole, hinge is set in the through hole of groove walls and nose stipule one end projection briquetting and nose stipule one end are hinged.

The groove quantity of described briquetting setting can be one or more (commonly used is two); Correspondingly, the number of slugs of nose stipule one end also is one or more (commonly used is two), and described projection stretches in the groove, and briquetting is connected with nose stipule one end.

Described fixed block is provided with the elastic component fixed orifice, and described elastic component one end stretches in the elastic component fixed orifice, and the projection of the other end and nose stipule one end is apical grafting mutually; The quantity of described elastic component fixed orifice (that is quantity of elastic component) is general identical with the number of slugs of nose stipule one end.

Described elastic component can be spring or spring leaf.

The utility model has following advantage and effect with respect to prior art: this adjustable glasses central sill stipule produces the elasticity corrective action by the flexible adjustment assembly that wherein is provided with, for the different states of wearing (it is different with distance between wearer's bridge of the nose mainly to be the glasses central sill), but this product automatic flexible is regulated the stipule position, to keep suitable snap-in force, thereby can effectively overcome difficult adjustment of stipule that existing single mount impeller structure glasses exist to adapt to the problem of the different user modes of different users and same user, use more simple, comfortable, safety; And this product can be conveniently used in existing various glasses form, also can be used for existing glasses are transformed, and the scope of application is wider.
