Description

The removable spectacle frame of nose holder

Technical field

The utility model relates to the removable spectacle frame of a kind of nose holder, belongs to the technical field of glasses.

Background technology

Traditional spectacle frame, its nose holder is to be fixed on the mirror holder by web member, cannot freely dismantle the nose holder, the size of nose holder also cannot be adjusted, and uses inconvenient.

After have the people to research and develop a kind of spectacle frame with detachable nose holder, see Chinese utility model patent 200820094848.5, it is made up of as shown in Figure 1 picture frame 10 and nose holder 20 as shown in Figure 2.Two mirror circles 101 and the central sill 102 that is connected two mirror circles 101 about picture frame 10 comprises are provided with locating slot 103 at the inwall of central sill 102, and the notch of locating slot 103 forms left and right sides edge 104.Two base bodies 201 and the connecting portion 202 that is connected two base bodies 201 about nose holder 20 comprises, on connecting portion 202, form plug connector 203, the left and right sides of plug connector 203 forms protruding tongue 204 respectively, and also vertically forming on the plug connector 203 increases flexible two profile grooves 205.During assembling, plug connector 203 is inserted in the locating slot 103, collude on the edge 104 that is stuck in locating slot 103 by protruding tongue 204, nose holder 20 is connected on the picture frame 10 securely, nose holder 20 can not split away off from central sill 102.When the holder 20 of desire dismounting nose, remove the card that colludes of protruding tongue 204 and edge 104, make plug connector 203 be able to from locating slot 103, extract out, promptly realize freely dismantling nose holder 20, be convenient for changing nose holder 20 and the size of adjusting nose holder 20.

But, anatomize said structure, be not difficult to find that there is following deficiency in it:

One, be used for limiting plug connector 203 is positioned at plug connector 203 from the protruding tongue 204 of locating slot 103 extractions the left and right sides, in order to guarantee that the protruding tongue 204 after the crimp can enter in the locating slot 103, the horizontal width of locating slot 103 can not design too for a short time, so, after the assembling, plug connector 203 can have the gap in the horizontal direction with locating slot 103, nose holder 20 can produce left and right sides deflection in the use, cause left and right sides base body 201 malpositions, picture frame 10 tilts, left and right sides mirror circle 101 one in front and one in back, the distance that is assembled in eyeglass in the mirror circle 101 and eyes is inconsistent, even change at any time, influence the use of wearing of glasses;

Two, fixing more firm in order to make plug connector 203 snap in locating slot 103, stable, can design plug connector 203 enough big, and in order to comply with the shape of central sill 102 and web member 202, plug connector 203 roughly along continuous straight runs is strip, this structure makes the degree of deformation of plug connector 203 horizontal directions be significantly smaller than the degree of deformation of vertical direction, and protruding tongue 204 is formed on the left and right sides of plug connector 203, so, guarantee the smooth of trip, can only offer on plug connector 203 increases flexible profile groove 205, so, not only complex structure is processed trouble, and between protruding tongue 204 and the web member 202 to be connected area little, fastness reduces, and has dismantled often the phenomenon that just occurs protruding tongue 204 breaking releasings easily, influences product quality.

In view of this, the inventor improves existing detachable nose holder structure, and this case produces thus.

The utility model content

Fundamental purpose of the present utility model is to provide a kind of nose holder removable spectacle frame, can left and right sides deflection after the assembling, wear effective.

Secondary objective of the present utility model is to provide a kind of nose holder removable spectacle frame, make simple in structure, firm, handling ease.

In order to reach above-mentioned purpose, solution of the present utility model is:

The removable spectacle frame of nose holder, form by picture frame and nose holder, two Jing Quan and the central sill that is connected two Jing Quan about picture frame comprises, inwall at central sill is provided with locating slot, the notch of locating slot forms edge up and down, two base bodies and the connecting portion that is connected two base bodies formed plug connector about the nose holder comprised on connecting portion, and the both sides up and down of plug connector form protruding tongue respectively.

Along continuous straight runs forms on the described plug connector increases flexible profile groove.

After adopting said structure, during the utility model assembling, plug connector is inserted in the locating slot, collude on the edge up and down that is stuck in locating slot by protruding tongue, the nose holder is connected on the picture frame securely, the nose holder can not split away off from central sill.When the holder of desire dismounting nose, rotate the nose holder up and down and be pulled outwardly simultaneously, can remove the card that colludes of protruding tongue and edge, make plug connector be able to from locating slot, extract out, promptly realize freely dismantling the nose holder, be convenient for changing the size of nose holder and the holder of adjustment nose.

The utility model is compared with existing structure, has the following advantages:

One, protruding tongue is positioned at the both sides up and down of plug connector, in order to guarantee that the protruding tongue after the crimp can enter in the locating slot, horizontal width can allow plug connector enter as long as the utility model can design the vertical width of locating slot bigger, so, after the assembling, plug connector and locating slot can not have the gap in the horizontal direction and only have the gap at vertical direction, in the use nose holder only can just take place with user's the bridge of the nose to rotate up and down and automatically the location, will never produce left and right sides deflection, guarantee left and right sides mirror circle self-consistentency, the eyeglass that is assembled in the mirror circle is consistent with the distance assurance of eyes, guarantees that wearing of glasses is effective;

Two, because the degree of deformation of plug connector horizontal direction is significantly smaller than the degree of deformation of vertical direction, be that plug connector rotates up and down that to produce distortion easier, the utility model is formed on protruding tongue the both sides up and down of plug connector, when assembling, as long as rotating the nose holder up and down presses simultaneously inwards, plug connector is fixed in locating slot, and when dismounting, be pulled outwardly simultaneously as long as rotate the nose holder up and down, plug connector is extracted out from locating slot, and the nonessential profile groove of on plug connector, offering, simple in structure, firm, handling ease;

Even three for assembly and disassembly better, also only need on plug connector along continuous straight runs to form a profile groove and get final product, be connected and still have than large tracts of land between protruding tongue and the web member at this moment, fastness is unaffected, determining does not have the phenomenon that protruding tongue breaking releasing just appears in the dismounting number of times, guarantees product quality.
