Abstract

The utility model discloses a non-hinge internal clamping type glasses earpiece which comprises a pile head (1) and a glasses earpiece (2), wherein the tail part of the pile head (1) is provided with a flute track (11), the head part of the glasses earpiece (2) is provided with a trepan boring (21), the tail part of the pile head (1) is inserted into the trepan boring (21) and can rotate freely, and the pipe wall of the trepan boring (21) is provided with an inward bulge (2222). The width of the bulge (2222) is smaller than the length of the flute track (11), and the bulge is exactly clamped in the flute track (11). The pile head (1) and the glasses earpiece (2) are movably connected through the engagement between the bulge (2222) and the flute track (11). The non-hinge internal clamping type glasses earpiece of the utility model has simple structure, and the component size of the utility model can be made more exquisite than the existing glasses earpiece.

Description

Hinge-less inner blocking type leg of spectacles

Technical field the utility model relates to the structural member of glasses non optical component, relates in particular to a kind of hinge-less inner blocking type leg of spectacles that makes the relative village of leg of spectacles head that certain scope of activities be arranged.

The existing leg of spectacles of background technology is connected with adopting hinge as the village is first, and adds the structure of other restriction leg of spectacles open angle, and its member is more, and technology is complexity, and the size of leg of spectacles can not do too for a short time, wears and feels heavier.

The summary of the invention the purpose of this utility model is to avoid the deficiencies in the prior art part and a kind of hinge-less leg of spectacles lighter and handier, simple in structure is provided.

The purpose of this utility model can realize by adopting following technical measures, design a kind of hinge-less inner blocking type leg of spectacles of forming by village head (disjunctor eyebrow beam), mirror leg, wherein village head can be a geometric configuration arbitrarily, its afterbody is milled with a step, mirror leg head has a circular bore, its aperture require will with the village end to end the diameter of portion be equal to.The village step that mills of portion end to end is grooved tracks, the head of described leg of spectacles is provided with trepanning, the afterbody of described village head inserts this trepanning and can freely rotate, described trepanning tube wall is provided with inside projection, this protruding width is littler and just in time be stuck in this grooved tracks than described grooved tracks, and described village head and leg of spectacles are by the flexible connection that engages between described projection and grooved tracks.

When leg of spectacles up time needle shaft rotates to the relative village end to end during approximately in line position of portion, the inwardly protruding of described mirror leg head trepanning tube wall and the end of grooved tracks are inconsistent, so can't rotate, mirror holder is in the state of normally wearing at this moment again.Because the degree of depth of described grooved tracks is about a line footpath, the village half, guaranteed that leg of spectacles can about 100 degree of turning anticlockwise and become collecting state.

This shows that hinge-less inner blocking type leg of spectacles structural manufacturing process of the present utility model is simple, the comparable existing leg of spectacles of its scantling is done more exquisitely.

The drawing of appended drawings is described as follows:

Fig. 1: the parts exploded view that is the utility model hinge-less inner blocking type leg of spectacles;

Fig. 2: the scheme of installation that is the utility model hinge-less inner blocking type leg of spectacles;

Fig. 3: two kinds of working state schematic representations that are the utility model hinge-less inner blocking type leg of spectacles.

The utility model is described in further detail below in conjunction with drawings and Examples.

Embodiment as shown in Figure 1, hinge-less inner blocking type leg of spectacles of the present utility model comprises the village 1 and leg of spectacles 2; 1 afterbody is provided with grooved tracks 11 in the village, the head of described leg of spectacles 2 is provided with trepanning 21, the afterbody in the described village 1 inserts in this trepanning 21 and can freely rotate, described trepanning 21 tube walls are provided with inside projection 2222, the width of this projection 2222 is littler and just in time be stuck in this grooved tracks 11 than the length of described grooved tracks 11, the described village 1 and the engage flexible connection of leg of spectacles 2 by 11 of described inwardly protruding 2222 and grooved tracks.

The inwardly protruding 2222 of described leg of spectacles 2 head trepannings 21 tube walls is the spherical crown shape, the width of this spherical crown be slightly less than the village 1 an afterbody grooved tracks 11 width but much smaller than the length of grooved tracks 11; Described leg of spectacles 2 can only slide along the length direction of described grooved tracks 11 with respect to the village 1, and the angular range of slip depends on the length and the degree of depth of grooved tracks 11.

Its scheme of installation as shown in Figure 2.The village 1 afterbody is aimed in leg of spectacles 2 heads boring 21 to be inserted, and then with anchor hole machine at certain angle and the requirement pit 222 that casts anchor, pit 222 protrusion mirror legs 2 head internal drillings this moment 21 tube walls, protruding position 2222 just is stuck in the grooved tracks that 1 afterbody mills out 11 of the village, because the gong cutter width of this grooved tracks 11 is equal to position, the hole diameter of the position, anchor hole 222 of mirror leg 2 heads, therefore the positioning action that connects the village 1 and mirror leg 2 is played in described anchor position 222.

Fig. 3 a is that spectacle frame is in the view when normally wearing, when mirror leg 2 is opened clockwise, because the village 1 maintains static, leg of spectacles 2 rotations are also followed in anchor hole 222 when rotating leg of spectacles 2, because the activity spaces 111 in the grooved tracks 11 are loose slots of mirror leg 2 tube walls projection anchor position 2222, the projection 2222 of mirror leg 2 borings 21 inwalls will be milled step position 1111 by the end of the village 1 grooved tracks 11 and be blocked during turn mirror leg 2 again; This moment, described leg of spectacles 2 up time needle shafts rotated to the relative village 1 afterbody position approximately in line, and the inwardly protruding 2222 of described leg of spectacles 2 head trepannings 21 tube walls is inconsistent with the end 1111 of grooved tracks 11.Because their turning axle is in the center, thus can't rotate again, thus determined the maximum open angle of the utility model mirror leg.

The another kind of duty of a leg of spectacles 2 and 1 a hinge inside, village when Fig. 3 b is the spectacle frame collection.When the counterclockwise cycle of leg of spectacles 2, follow mirror leg 2 and rotate in the hole inwardly protruding 2222 of 21 tube walls of mirror leg 2 heads, because the grooved tracks 11 of the village 1 afterbody is its line footpath half, so there is certain activity space 111, its rotary moveable angle of just in time enough described protruding 2222, this rotating angular range is between 90 to 110 degree, and present embodiment is approximately 100 degree, amounts to desired rotating range thereby reached leg of spectacles 2 collections.

The existing relatively combined lens leg that screws of hinge-less inner blocking type leg of spectacles of the present utility model is undoubtedly a kind of progress, and its structure seems simply, has but embodied a kind of trend that a kind of mechanical principle and glasses fashion are merged.
