Description

A kind of glasses

Technical field

The utility model relates to a kind of functionally wears product, and more particularly, it relates to a kind of glasses.

Background technology

At present, glasses on market are made up of mirror holder and eyeglass, mirror holder comprises temple and picture frame, eyeglass is entrenched on the picture frame of mirror holder, it is hinged that temple and picture frame pass through hinge chain, hinge chain comprises the first chain bar and the second chain bar that are fixedly connected with temple with picture frame respectively, both laminating by screw run through realize hinged, but, the defect existed has, repeatedly repeat to move temple, screw can produce loosening, be separated with the second chain bar with the first chain bar, thus cause the first chain bar to be separated with the second chain bar, affect the normal use of glasses, in addition, because mirror holder is all buy in the later stage, cause being worn on the head either large or small, when the mirror holder selected is slightly little, the temple made by harder objuct matter such as resins clamps head part both sides can produce pain, affect wearer normally to use.

Utility model content

For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of glasses preventing temple to be separated with picture frame.

For achieving the above object, the utility model provides following technical scheme:

A kind of glasses, comprise mirror holder and eyeglass, described mirror holder comprises temple and picture frame, described eyeglass is entrenched on picture frame, it is hinged that described temple and picture frame pass through hinge chain, described hinge chain comprises the first chain bar and the second chain bar that are fixedly connected with temple with picture frame respectively, both laminating by screw run through realize hinged, the end face of described first chain bar the second chain bar dorsad offers groove, described groove is arranged on the threaded hole one end of inserting for screw, anti-falling piece and spring is provided with successively according to screw direction of insertion in described groove, the inwall of described groove is provided with the slide block arranged along spring pressurized direction, the outer wall of described anti-falling piece offers the chute for coordinating with slide block, described screw is provided with and coordinates with anti-falling piece and for screw single direction rotation fixture block, described temple is arranged with leg cover, described leg cover comprises the sleeve pipe be set in temple and the bed course be wrapped in outside sleeve pipe.

The utility model is set to further: the end face of described anti-falling piece spring is dorsad convexly equipped with wedge, the inclined-plane of described wedge from the end face of anti-falling piece upwards and tilt along screw sense of rotation, described fixture block is provided with the oblique surface for coordinating with the inclined-plane of wedge, and described fixture block coordinates the one-directional rotation being used for screw with wedge.

The utility model is set to further: described anti-falling piece is set to cylindrical, and described wedge is provided with two or more and is centrosymmetric setting along the end face of anti-falling piece.

The utility model is set to further: described fixture block and screw are one-body molded by forging.

The utility model is set to further: described anti-falling piece and wedge shaping by moulding.

By adopting technique scheme, spring and anti-falling piece are once put into groove, by screw from anti-falling piece from inserting and being threaded with threaded hole, during rotating screw, anti-falling piece is coordinated by chute and slide block makes anti-falling piece motionless relative to the first chain bar, fixture block can only slide along the inclined-plane of wedge, being coordinated with fixture block by wedge prevents screw from reversing, thus prevent screw from departing from threaded hole, reach the effect of anticreep, leg cover is set on head, soft bed course replaces harder temple directly to contact with human body head, better comfortable, therefore, avoid because of in selecting slightly little mirror holder to wear term, clamp head part both sides and can produce pain, impact is normal to be used.
