Abstract

The utility model discloses a bow-shaped plastic spring sheet glasses leg. A plastic spring sheet in the bow shape is installed on the inner side of the glasses leg, the front end of the plastic spring sheet is pivoted with the glasses leg at the position near a glasses corner, the middle portion of the plastic spring sheet is pivoted with the tail end of the glasses leg, and an ear supporter is formed at the rear end of the plastic spring sheet. The plastic spring sheet on the glasses leg can automatically adjust curvature according to different head shapes when in wearing, thereby leading apair of glasses to be positioned firmly on the head portion, and enabling a user to feel safer and more comfortable when wearing the glasses.

Description

Arc plastic cement shell fragment mirror leg

Technical field

The utility model relates to a kind of mirror leg of glasses, and is relevant with the structure of the plastic cement shell fragment that is provided with on the mirror leg.

Background technology

Existing glasses are when wearing use, and glasses just are fixed on head by three-point fix in Er Tuo and the nose, and the mirror leg often and between the both sides of head leaves spacing.Because the mirror leg generally all is the rod member of a bending, the mirror leg is once moulding, its camber is just fixing, and the spacing between the right and left mirror leg is also just fixing, therefore, when glasses are worn when loosening, the mirror leg can't be by automatically regulating flexibility, and the variation of the easy excuse of glasses position and cause integrated deflection is particularly when motion, glasses come off easily, poor stability.For effectively fixing glasses, design the mirror leg tight slightly usually, the elastic deformation because of its material self when wearing clamps head, and still, this also is that the part of mirror leg contacts with head, and tight slightly mirror leg causes easily to temporal extruding, and comfortableness is poor.

The inventor researchs and develops out a kind of arc plastic cement shell fragment mirror leg at the problems referred to above, safety and comfortable when making eyeglasses-wearing, and this case produces thus.

The utility model content

The purpose of this utility model is to provide a kind of arc plastic cement shell fragment mirror leg, and the plastic cement shell fragment on the mirror leg can be regulated flexibility automatically with the head dummy difference when wearing, make glasses at the head firm position, and order is worn safer, comfortable.

To achieve these goals, the technical solution of the utility model is as follows:

Arc plastic cement shell fragment mirror leg is equipped with the plastic cement shell fragment at the mirror inboard leg, and the plastic cement shell fragment is arc, and the front end of plastic cement shell fragment and mirror leg are articulated near the pitch-angle place, and the tail end of the middle part of plastic cement shell fragment and mirror leg is articulated, and the rear end of plastic cement shell fragment forms the ear holder.

The tail end of described mirror leg bends inwards and forms a pin joint seat, and also to projecting inward formation one pin joint seat, the front end of plastic cement shell fragment and middle part are articulated in respectively on the corresponding pin joint seat mirror leg near the pitch-angle place.

Described mirror leg adopts light materials such as almag or resin to make.

After adopting such scheme, the utility model is before wearing use, and arc plastic cement shell fragment is the form that inwardly encircle to excurvation, middle part at two ends; When wearing use, after head produces squeezing action to the plastic cement shell fragment, the plastic cement shell fragment is the outwards form of arch of inward at both ends lateral bending song, middle part, and regulate flexibility automatically with different head dummys, make whole mirror leg be close to head fully, and can not produce extruding, add in the nose support location at the bridge of the nose to the head temple, make glasses integral body at the head firm position, order is worn safer and comfortable.

Below in conjunction with the drawings and specific embodiments the utility model is described further.

Embodiment

As depicted in figs. 1 and 2, be preferred embodiment of the present utility model.

Arc plastic cement shell fragment mirror leg, mirror leg 1 are to adopt light materials such as almag or resin to make.In mirror leg 1 inboard plastic cement shell fragment 2 is housed.

Plastic cement shell fragment 2 is arc.The front end 21 of plastic cement shell fragment 2 is articulated near pitch-angle 3 places with mirror leg 1, and the middle part 22 of plastic cement shell fragment 2 is articulated with the tail end of mirror leg 1, and the rear end 23 of plastic cement shell fragment 2 forms the ear holder.For the ease of articulating, this embodiment bends inwards the tail end of mirror leg 1 and forms a pin joint seat 11, also to projecting inward formation one pin joint seat 12, the front end 21 of plastic cement shell fragment 2 and middle part 22 are articulated on the corresponding

pin joint seat

12 and 11 by screw 4 respectively at mirror leg 1 close pitch-angle 3 places.

The utility model is before wearing use, and arc plastic cement shell fragment 2 is front end 21 and rear end 23 to the inside forms of arch in excurvation, middle part 22.When wearing use, after the middle part 22 generation squeezing actions of head to plastic cement shell fragment 2, plastic cement shell fragment 2 is front end 21 and rear end 23 is inwardly curved, the form of middle part 22 outside arches, and regulate flexibility automatically with different head dummys, make whole mirror leg not only by the ear carriage on ear, and be close to head fully, and can not produce extruding to the head temple, add in the nose support location at the bridge of the nose, make glasses integral body at the head firm position, order is worn safer and comfortable.

The above is preferred embodiment of the present utility model only, is not the restriction to this case design, and all equivalent variations of doing according to the design key of this case all fall into the protection domain of this case.

Claims

1, arc plastic cement shell fragment mirror leg, it is characterized in that: at the mirror inboard leg plastic cement shell fragment is housed, the plastic cement shell fragment is arc, and the front end of plastic cement shell fragment and mirror leg are articulated near the pitch-angle place, the tail end of the middle part of plastic cement shell fragment and mirror leg is articulated, and the rear end of plastic cement shell fragment forms the ear holder.

2, arc plastic cement shell fragment mirror leg as claimed in claim 1, it is characterized in that: the tail end of described mirror leg bends inwards and forms a pin joint seat, also to projecting inward formation one pin joint seat, the front end of plastic cement shell fragment and middle part are articulated in respectively on the corresponding pin joint seat mirror leg near the pitch-angle place.
