Abstract

The utility model relates to a pair of glasses, in particular to a pair of rotating-feet folding glasses which is provided with a rotating mechanism. The rotating mechanism is composed of a pin shaft and a ferrule. The pin shaft and the ferrule are positioned on the connection of the glasses frame and the glasses feet; the axial line of the pin shaft and the ferrule are horizontal and parallel to the glasses frame surface. A hole is positioned in the middle of the ferrule and can contain the pin shaft. The pin shaft and the ferrule are matched movably. By such a rotating mechanism, the pin shaft can rotate along the ferrule, and then drives the glasses feet to rotate at random. The claw head can easily rotate to the position parallel to the glasses frame; the feet thread can be folded on the upper and the lower sides of the glasses frame. The pair of folding glasses of the utility model takes up small area, and is applicable to put in a smaller and thinner glasses box, and is thereby more convenient to carry.

Description

Change the pin folding glasses

Technical field

The utility model relates to a kind of glasses, particularly a kind of commentaries on classics pin folding glasses.

Background technology

Generally use folding glasses on the market now, folding glasses has easily folding, advantage such as easy to carry, wherein Chinese utility model ZL01265205.9 patent, it is a kind of commentaries on classics pin folding glasses, comprise picture frame, eyeglass, the mirror pin, wherein joining design one rotational structure on the mirror pin head of the built-in spring that is welded on the picture frame, rotational structure comprises the fixing feet head, spring, lasso, rotate the pin head, its sub-unit fixing feet head that rotates the pin head is welded on the picture frame, the long end of spring afterbody is stuck on the fixing feet head, external lasso, the short end of spring afterbody is stuck in and rotates the pin head, with screw retention.When left and right sides mirror pin all is in when closing up state, left mirror pin pressurized rotates along the eyeglass in-plane, can rebound rapidly behind the cancellation pressure.Because this rotational structure is too complicated, produce the each several part part of this rotational structure and they be assembled into whole rotational structure not only time-consuming but also take a lot of work; And rotating on the pin head also design has position limiting structure, make the slewing area of rotating the pin head certain, therefore want to rotate the mirror pin, must be all to be at left and right mirror pin to close up state, could rotate during left side mirror pin pressurized, and can not arbitrarily angled at any time rotation mirror pin, the inconvenience that folds brought.

Summary of the invention

It is a kind of simple in structure, easy to assembly that the purpose of this utility model is to provide, and can realize the random rotation of mirror pin, the commentaries on classics pin folding glasses of folding convenient practicality.

For achieving the above object, the utility model adopts following structure: this commentaries on classics pin folding glasses has rotating mechanism, this rotating mechanism is made up of a bearing pin and a lasso, bearing pin and lasso are arranged on the junction of picture frame and mirror pin, both axial lines are level and be parallel to glasses frame surfaces all, be formed centrally the hole that can hold bearing pin in lasso, bearing pin and lasso constitute movingly.

Owing to adopted such scheme, this rotating mechanism has been arranged, bearing pin can rotate around lasso, driving the mirror pin arbitrarily rotates, the pawl head just can easily forward the position parallel with picture frame to, and the pin silk then can directly fold into the both sides up and down of picture frame, and the area of the glasses that such pair has been folded up is very little, be fit to put into littler thinner spectacle case, carry more convenient.

Embodiment

As Fig. 1,2, shown in 3, commentaries on classics pin folding glasses in the present embodiment has rotating mechanism 6, described rotating mechanism 6 is by the lasso 62 on the top that is connected an end on the pawl head 51 that is arranged on mirror pin 5 with picture frame 1 and be arranged on a left side, the bearing pin 61 in right picture frame 1 outside is formed, the axial line of bearing pin 61 and lasso 62 is level and be parallel to glasses frame surfaces all, in lasso 62, be formed centrally the hole that can hold bearing pin 61, bearing pin 61 tops are provided with the shaft shoulder 612, the shaft shoulder 612 external diameters are greater than the internal diameter of lasso 62 and are not more than the external diameter of lasso 62, bearing pin 61 roots are suitable to the length and the lasso 62 of the shaft shoulder 612, and bearing pin 61 and lasso 62 constitute movingly.During folding glasses, as long as rotate the mirror pin, bearing pin 61 on it can be produced extruding with lasso 62, force lasso 62 to expand outwardly, because lasso 61 1 sides have a joint-cutting 621, have certain elasticity, make things convenient for lasso 62 to expand outwardly, make it and easily to turn over an angle, also be convenient to install and change mirror pin 5 in addition around bearing pin 61.This rotating mechanism 6 has been arranged, and pawl head 51 just can forward the position parallel with picture frame 1,52 both sides up and down that can directly fold to picture frame 1 of pin silk at an easy rate to.For better folding glasses, make things convenient for the location between bearing pin 61 and the lasso 62, can also be on described rotating mechanism 6 corresponding normal when using glasses, mirror pin 5 residing positions and front and back are rotated 90 positions when spending described detent mechanism are set, this detent mechanism by in the outer ring of bearing pin 61 along the convex tendon 611 of bearing pin 61 bus settings and on the inwall of lasso 62 groove 622 of corresponding held convex tendon 611 form.When rotating mirror pin 52, when the lasso 62 on it rotated around bearing pin 61, convex tendon 611 can outwards push up lasso 62, because the joint-cutting 621 on the lasso 62 has certain elasticity, so lasso 62 just is easy to expand outwardly, can easily rotate around bearing pin 61.When lasso 62 turns an angle, the convex tendon 611 on the bearing pin 61 enters in the groove 622 on the lasso 62, plays the effect of location.

Convex tendon 611 is not unique with the position of groove 622 in the foregoing description, can convex tendon 611 be set on bearing pin 61 yet, and groove 622 is set on lasso 62, can realize the location yet.

The bearing pin 61 on the rotating mechanism 6 and the position of lasso 62 can exchange, and also bearing pin 61 can be arranged on the top that is connected an end on the pawl head 51 of mirror pin 5 with picture frame 1, and lasso 62 is set on the outside of left and right picture frame 61.
