Description

The no screw nose pad arm fixed mechanism of glasses

Technical field

The utility model relates to the improvement of eyeglass configurations, particularly relates to the processing of not using small part such as fixed screw or not carrying out trouble such as soldering, and the no screw nose pad arm fixed mechanism of the glasses of nose pad arm just can be installed simply.

Background technology

As everyone knows, glasses are assembled by many parts, and about central portion both sides of frame are equipped with pair of right and left nose pad arm before the glasses, and front end is provided with the nose pad.

But, this nose pad arm often is fixed on spectacle bridge or the spectacle-frame, in the past, methods (for example TOHKEMY 2002-107675 communique) such as this fixing means adopts that all screw is fixed, but, handling small part needs skill and masterful technique, expends time in and bothers, and might lose the fixedly part of usefulness because of error simultaneously.

Again, fixing means also has the situation (for example TOHKEMY 2005-122064 communique) of methods such as adopting soldering or welding, but needs corresponding apparatus because of the damage place under repair time, can not carry out complicated operations in the shop, and time-consumingly takes the labour.

Summary of the invention

Structurally there is aforesaid problem in the utility model in view of existing glasses and makes, the purpose of this utility model is, a kind of processing of not using small part such as fixed screw or not carrying out trouble such as soldering is provided, the no screw nose pad arm fixed mechanism of the glasses of nose pad arm just can be installed simply.

Formation of the present utility model mainly comprises: the preceding frame F that utilizes spectacle bridge 2 to link pair of right and left lens 1 is installed on the nose pad arm 3 on the glasses, it is characterized in that, nearly eyes at described spectacle bridge 2 are provided with a plurality of insertion pins 21 that are parallel to each other side-prominently, described nose pad arm 3 is for extending two supporting arm 3b from the both sides of pedestal 3a, be respectively equipped with nose pad 31 on each front end of described two supporting arm 3b, be provided with fixed orifice 41 on the retaining element 4 that material by the energy elastic deformation constitutes with on the relative position that inserts pin 21, the insertion pin 21 of described spectacle bridge 2 inserts in the fixed orifice 41 of retaining element 4 with the tight shape of embedding.

Adopt fixed mechanism of the present utility model, nose pad arm is to extend two supporting arms to form from the both sides of pedestal, be respectively equipped with the nose pad on each front end of described two supporting arms, simultaneously on the retaining element that the material by the energy elastic deformation constitutes, relative position at described insertion pin forms fixed orifice, under state with the pedestal clamping of described nose pad arm, the insertion pin of described spectacle bridge is inserted in the fixed orifice of retaining element with the tight state of embedding, by means of this, nose pad arm can be installed on the spectacle bridge.The utility model has the advantages that small parts such as not using fixed screw, do not carry out the processing of trouble such as soldering, nose pad arm just can be installed simply, for the practical value of glasses than higher.

Embodiment

Further specify embodiment of the present utility model below in conjunction with accompanying drawing.

Embodiment one

Referring to Fig. 1～Fig. 5.1 is lens among the figure, 2 spectacle bridges for binding pair of right and left lens 1, and the 3rd, nose pad arm, this nose pad arm 3 are to extend two supporting arm 3b to form from the both sides of pedestal 3a, are respectively equipped with nose pad 31 on each front end of described two supporting arm 3b.

Retaining element 4 is made of the material of energy elastic deformation, and for example nylon is soft synthetic resin such as resin, acrylic resin, synthetic rubber, forms fixed orifice 41 on the relative position of described insertion pin 21.

The nose pad arm of replacing of the present utility model glasses freely, referring to Fig. 1, it is the mechanism of nose pad arm 3 usefulness being installed on the glasses that utilize the preceding frame F that spectacle bridge 2 links pair of right and left lens 1 having, structurally, at first a plurality of (being two in the present embodiment) that be parallel to each other is set side-prominently insert pin 21 (referring to Fig. 2) at the nearly eyes of described spectacle bridge 2.In the present embodiment, sell in the insertion of spectacle bridge 2 and to be provided with the tight projection 21a of embedding on 21 side faces, can be not easy to extract so that insert pin 21.
