Abstract

The utility model discloses diopter adjustable spectacles which comprises a spectacle support, a rotary spectacle frame, a moveable connecting rod, a spectacle leg and an adjusting screw rod. Screw rods or screws are used to connected all the parts. The utility model is mainly characterized in adjusting the spectacle degrees by the move of the moveable connecting rod and the rotation of the rotary spectacle frame. Because of spectacle lens of the diopter adjustable spectacles can be used in the range of a certain degrees, various degrees of spectacles can be manufactured only by dividing the adjustable region into different grades without grinding every degree of the spectacles into ophthalmic lens. The utility model has the advantages of labor saving, time saving, material saving and flexible and convenient use.

Description

Diopter adjustable spectacles

The utility model relates to a kind of daily living article, especially a kind of adjustable glasses that are used to correct defects of vision.

At present, we are normally used to be the glasses of the various fixedly number of degrees, because also having only the glasses of this fixedly number of degrees in the market sells, and for numerous A nearsighted persons, wears glasses must just can be joined mirror through optometry, and optometry and join the mirror aspect and spend many time and efforts, and the number of degrees of institute's optometry often not exclusively match with the required number of degrees of correcting defects of vision, so do not reach its intended purposes, simultaneously for those at ordinary times with the glasses of the shallow number of degrees, and reading study or change the people of high degree glasses when seeing a film again not only increases many inconvenience, and increases burden economically.

The purpose of this utility model is for overcoming the adjustable glasses of a kind of number of degrees that above-mentioned weak point designs, the concavees lens of the usefulness of generally correcting defects of vision, its purpose is exactly that light with object image-forming reflects by concavees lens, its imaging point is dropped on the retina, when we wear glasses reading, closely, during the light foot, in order to reduce light, eyeball protrudes retina to recurve, the whole eyeball prolate that just becomes, if retina muscle has lost elasticity when closely reading a book for a long time, can not homing, as at this moment wearing glasses when the distant place is looked into the distance, the vitreum of eyeball front portion just needs the flat of change, so that more weak light far away enters eyeball more, but because retina muscle follows the string, with the glass eye sphere gap from increasing, before the image point will fall within retina at a distance, such thing far away had not just seen, as at this moment lens being rotated a certain angle, to change the ray refraction angle, image drops on the retina again after making light by eyeball, and what at this moment distant objects was just seen has known, so can realize above-mentioned purpose in this way.

Description of drawings:

Accompanying drawing 1 is a wiring layout of the present utility model.

Accompanying drawing 2 is that A of the present utility model is to view

Accompanying drawing 3 is structural drawing of mirror holder of the present utility model (1), rotation picture frame (2), movable rod (3) and mirror leg (4)

The utility model will be further described below in conjunction with accompanying drawing, and it is made up of spectacle frame (1), rotation picture frame (2), movable rod (3), mirror leg (4), small screw (5) and primary screw (6) etc.Wherein mirror holder is long narrow shape rod member, there are 90 ° of crotches at two, vertical with crotch inwardly have a duplex support, circular hole is arranged on the support, there are two supporting legs vertical with it mirror holder central authorities below, an elongate slots is respectively arranged on the crotch intermediate transverse girder at supporting leg and two, and groove width is a bit larger tham the diameter of small screw (5), its available metal or mould firmly and make; Rotation picture frame (2) is the framework of an approximate square, its have on one side one with the perpendicular duplex support of framework face, circular hole is arranged on the support, framework top central authorities are welded with a small screw (5), rotation picture frame available metal material or duroplasts are made, movable rod (3) is a narrow long type thin plate, the one head has the slightly long narrow groove of an opening, make narrow groove both sides form a duplex support, screw is arranged above, on perpendicular to long narrow template face, be welded with a small screw (5), connecting rod is made with metal material, mirror leg (4) is an elongated shape rod member, and one crooked slightly, and flexibility is about 70 °～80 °, three supports are arranged on the other end, screw is arranged on it, and three supports match with duplex support on the mirror holder (1), and circular hole and screwhole diameter on it are identical, there is elongate slot three supports the inside on the mirror leg, there is scale the groove top, indicates the eyeglass lens power that needs adjusting, and the mirror leg is made with metal material or duroplasts.Duplex support on the movable rod matches with duplex support on the picture frame, screw and Circularhole diameter on it are identical, simultaneously it with the mirror leg on three supports on screw and the Circularhole diameter on the duplex support on the mirror holder all match with the diameter of primary screw (6).To rotate small screw (5) on the picture frame (2) packs in the elongate slot of mirror holder (1), fix with nut, use primary screw (6) that the mirror leg is connected with the rotation picture frame with mirror holder, movable rod respectively, and small screw on the movable rod is packed in the elongated slot on the mirror leg, use nut screwing clamping.When needs are adjusted eyeglass lens power, nut is unscrewed, move forward movable rod to the appropriate location, at this moment picture frame also rotates a certain angle, and after mixing up, nut screwing clamping is got final product again.

The utility model has following advantage compared with the prior art: the utility model can be regulated eyeglass lens power within the specific limits, broken the defective of the glasses of traditional fixedly number of degrees, thereby prevented because of long-term wear a pair of spectacles the worn-out sick of the further decline that causes eyesight of closely reading a book; Use this kind glasses can not need optometry, and only need just can obtain suitable oneself glasses through suitable selection, simultaneously owing to a kind of eyeglass can use in certain number of degrees scope, as long as adjustable zone is divided into the glasses that different class just can be made the various number of degrees, and need not the glasses of each number of degrees are all worn into eyeglass, but so both savings of labor saves time, can save material again, and flexible and convenient to use.
