Description

A kind of fixing structure for head of glasses

Technical field

The utility model is related to a kind of Glasses structure to improve, more particularly to, a kind of pile crown of rimless eyeglasses is fixed Structure.

Background technology

In the eyeglass device of prior art, be it is attractive in appearance there is a kind of eyeglass device of Rimless, this glasses remove glasses The clear transparent of eyeglass can be highlighted after frame so that wearer is elegant in appearance on the whole.But assembling of the rimless eyeglasses to eyeglass It is more difficult, it is due to according to different material and function and usage, such as different especially in the structure of pile crown connection leg of spectacles Myopia degree, eyeglass has a different thickness, but prior art all more or less presence problem of fixing structure for head.

Common fixing structure for head, as depicted in figs. 1 and 2, the correspondence position on Rimless eyeglass 100 is set one There is a hole portion 101, for assembling pile crown 300；The pile crown 300 by the leg of spectacles 200 that is articulated and connected, on the pile crown 300 One is provided with for the bolt 301 through the hole portion 101, the bolt 301 is generally made of metal, can be together with the stake Header structure is wholely set, or is formed by welding.With the nut 302 that the threaded adapter of bolt 301 is provided with a metal material, with And a pad 303 is provided between nut 302 and eyeglass 100, so as to realize being incited somebody to action by the cooperation of nut 302 and bolt 301 The pile crown 300 and leg of spectacles 200 are fixed on the eyeglass 100.

Meanwhile, waved to realize resisting, a groove portion 102, and correspondence are additionally provided with the stake in the side of the eyeglass Be provided with first 300 one for resist the post portion 304 waved, by being adapted to for post portion 304 and the groove portion 102, realize wearing Prevented during glasses and resisted glasses it is integrally-built wave caused by pile crown and ophthalmic len between structural failure.

In this kind of fixing structure for head, the cooperation of nut and bolt is the cooperation of metal and metal, it is easy to used Released in journey；Simultaneously as lens thickness of the prior art differs, therefore in above-mentioned existing fixing structure for head, when running into During the relatively thin situation of eyeglass 100, it is necessary to which the bolt 301 to stretching out long is processed, as shown in Fig. 2 for example clipping is fallen, but Easily cause the bolt after clipping and leave spine, cause the injury to user.

In common fixing structure for head, secondly as shown in Figure 3 and Figure 4, it is provided with two hole portions on ophthalmic len 100 101 ', and correspondence be provided with pile crown 300 two have internal lock groove mast 301 ', be also correspondingly arranged on an adaptation this two Individual mast 301 ' cap member 302 ', the connecting portion of the cap member 302 ' is provided with pipe portion slightly long, to coordinate the mast 301 ‘.The benefit of this kind of implementation is that, without additional means, such as rotary screwing thread of foregoing implementation coordinates, but for thicker For ophthalmic len, the cap member 302 ' will be shorter with the mating connection part of the mast 301 ', connects insecure.

Therefore, prior art has yet to be improved and developed.

Utility model content

The purpose of this utility model is to provide a kind of fixing structure for head of glasses, realizes a kind of both firm assembly connection Glasses fixing structure for head, can realize again for different-thickness eyeglass assemble.

The technical solution of the utility model is as follows：

A kind of fixing structure for head of glasses, it includes being arranged at least hole portion on eyeglass, and sets and glasses The connected pile crown of leg, and the bolt for fitting through the hole portion is provided with the pile crown；Wherein, it is relatively described in the eyeglass The opposite side of bolt sets the pipe fitting of a plastic cement material, for rotating the bolt that is spirally connected.

The fixing structure for head of described glasses, wherein, the outboard end of the pipe fitting is set to a nut portion.

The fixing structure for head of described glasses, wherein, the nut portion is set to hexagonal (hexagon)nut portion.

The fixing structure for head of described glasses, wherein, be additionally provided with the inside of the bolt on the pile crown for The anti-post portion waved, and correspondence is provided with the groove portion for being adapted to the post portion in the side of the eyeglass.

The fixing structure for head of described glasses, wherein, the nut portion lower section of the pipe fitting is additionally provided with one for stopping Shoulder.

The fixing structure for head of a kind of glasses provided by the utility model, as a result of the pipe structure of plastic cement material Realization is adapted to realization with bolt, and its assembly technology is simple, and fixation is more firm, and can adapt to the eyeglass assembling of different-thickness.

Specific embodiment

Preferred embodiment of the present utility model is described in detail below.

A kind of fixing structure for head of glasses provided by the utility model, as shown in Figure 5 and Figure 6, itself and prior art Compare, the characteristics of be comprehensive two kinds of prior arts, the improvement for carrying out is included in the hole portion 101, Yi Ji set on eyeglass 100 The bolt 301 set in the pile crown structure 300 of leg of spectacles 200 is connected, adaptation institute can be fixedly connected through the hole portion 101 State pile crown.The pipe fitting 400 for being provided with a plastic cement material is adapted with the bolt 301, the pipe fitting 400 can be spirally connected by rotation On the bolt 301.The bolt 301 and the eyeglass 100, the length long enough of the pipe fitting 400 are fixed for convenience, it is sufficient to Extend in the hole portion 101, the pad between the bolt 301 and eyeglass hole portion 101 can be turned into every part.

The outboard end of the pipe fitting 400 is provided with a nut portion 401, and the nut portion 401 is a hexagonal (hexagon)nut shape, when Other nut shapes can also be so used, as long as there is the instrument of adapting operation.

Because the utility model is using the pipe fitting 400 of plastic cement material, bolt 301 is more firm with being adapted to for pipe fitting 400, does not allow Easily release.Meanwhile, regardless of the eyeglass of thickness, seem it is all to coordinate attractive in appearance from inner side.

In the fixing structure for head preferred embodiment of glasses described in the utility model, as shown in Figure 7 and Figure 8, the pipe Part 400 the downside in the nut portion 401 be additionally provided with one for stop shoulder 402, it is too deep in assembling process to prevent Screw in the hole portion 101；The hollow lumen of the pipe fitting 400 is slightly less than the major diameter of thread of the bolt 301, so as to facilitate State being engaged for pipe fitting 400 and the bolt 301.

In the fixing structure for head of the glasses, the inner side of the bolt 301 is additionally provided with one on the pile crown 300 Post portion 302, and correspondence is provided with a groove portion 102 in the lateral location of the eyeglass 100, can be used by the adaptation of the structure To prevent glasses waving during wearing, so as to ensure being stably connected with for the fixing structure for head.

Obvious pile crown structure described in the utility model is not limited in connecting leg of spectacles, the bridge of the nose between eyeglass and eyeglass Link position, it would however also be possible to employ said structure, and the utility model should also be belonged to using the product of the utility model said structure Protection domain.

It should be appreciated that for those of ordinary skills, can according to the above description be improved or converted, And all these modifications and variations should all belong to the protection domain of the utility model appended claims.
