Description

Frame stretches tight

Technical field

The utility model relates to a kind of frame that stretches tight, and relates in particular to the employed frame that stretches tight of a kind of embroidery.

Background technology

Along with the continuous development of clothes and ornaments, it is also more and more universal to embroider, and no matter is tradition and modern computerized embroideries, needs all that a kind of auxiliary mutually instrument---frame stretches tight.

At present in the various frame that stretches tight that uses,, finish the fastening of lining, at home and abroad so that embroider though material and different modeling all are by uses (as shown in Figure 1) that combine of an outer ring 11 and an inner ring 12.In the frame use of stretching tight, fastening for lining is able to, lining by the outer ring the inboard and during the outside of inner ring, need be the cooperation of interference, shown in A among the figure, otherwise loosening easily.Like this, make many linings after through the interference extruding, impression can be left in the lining surface, even can injure lining, even lining washing and flatiron processing also are difficult to eliminate impression, influences quality and attractive in appearance.

Summary of the invention

The utility model is the frame that stretches tight with flexible fastening effect that can to injure the shortcoming of lining when the existing frame that stretches tight uses and provide in order to solve.

The technical measures that the utility model is taked are: a kind of frame that stretches tight, an outer ring and an inner ring by tabling constitute, be characterized in, each is made of described outer ring and inner ring the similar and relative opened type framework of cross sectional shape, see from the cross section respectively to comprise a long limit, a minor face, and connect long limit and minor face is the fillet of one that its oral area is one can hold the depressed part of another circle minor face loosely; In the time of in inner ring is entrenched in the outer ring, the minor face of outer ring/inner ring pine relatively is embedded in the depressed part of inner ring/outer ring.

Above-mentioned a kind of frame that stretches tight, wherein, from the cross section, described outer ring comprises a long limit, a minor face, and connects long limit and minor face is the base of one, and its oral area is a depressed part that makes progress.

Above-mentioned a kind of frame that stretches tight, wherein, from the cross section, described inner ring comprises a long limit, a minor face, and connects long limit and minor face is the top margin of one, and its oral area is a downward depressed part.

Because the utility model has adopted above technical scheme, when being embedded in lining between housing and the inside casing, because the minor face of two circles is embedded in the depressed part of another circle relatively, lining forms horizontal serpentine at the depressed part of these two circles, flexible is fastening, therefore impression can be on lining, do not produced, more the situation that weighs lining wounded can be do not produced.

Description of drawings

Concrete structure of the present utility model is further provided by following embodiment and accompanying drawing thereof.

Fig. 1 is the stretch tight structural section schematic diagram of frame user mode of prior art.

Fig. 2 is the structural section schematic diagram of the utility model user mode.

The specific embodiment

See also Fig. 2.A kind of frame that stretches tight of the utility model is made of an outer ring 21 and an inner ring 22 of tabling, and each is made of described outer ring and inner ring the similar and relative opened type framework of cross sectional shape.Each is made of described outer ring of present embodiment and inner ring similar and relative " г " shape frame of cross sectional shape.From the cross section, wherein: the outer ring comprises that long limit of long limit 211, a minor face 212 and connection and minor face are the base 213 of one, and central closing is a depressed part that makes progress 214; Inner ring comprises that a long limit 221, a minor face 222 and the long limit of connection and minor face are the top margin 223 of one, and central closing is a downward depressed part 224; In the time of in inner ring 22 is entrenched in outer ring 21 relatively, the minor face outer wall of inner ring is fitted in the inwall on long limit, outer ring, and the minor face 212,222 of " г " of two circles is embedded in respectively in the depressed part 224,214 of another circle body relatively.

Outer ring described in the utility model and inner ring can respectively be that integrally closed circle body constitutes, in order to make the utility model frame that stretches tight be fit to various linings 10, also can be wherein have in outer ring and the inner ring one for integrally closed, another is for regulating closed formation, also can be outer ring and inner ring and be and regulate closed formation.Closed outer ring of described adjusting or inner ring are by constituting at the added degree of tightness governor motion in this circle body place of wrecking, described degree of tightness governor motion comprise be located at respectively circle body wreck the falling of two ends, place, along screw, fall, regulate bolt at this along connecting one in the screw, set firmly an adjustment disk in the middle of regulating bolt, regulate the turnover of bolt in screw by the turn of selection adjustment disk, thus the degree of tightness of having regulated circle body.This degree of tightness governor motion is a prior art, so ominous stating, also accompanying drawing not.

Outer ring described in the utility model and inner ring can be different shape, as long as two circle bodies can be adaptive and can minor face be entrenched in the depressed part of another circle mutually.

During use, inner ring is entrenched in the outer ring relatively, two the circle minor face be embedded in the depressed part of another circle respectively relatively, because the minor face of outer ring and the minor face of inner ring are set in the interior flange that forms of the depressed part of another circle respectively, when lining 10 passes through this two flanges place, lining is promptly along with flange shape has changed angle and direction, increased lining and stretch tight resistance and frictional force between the frame, thereby satisfy lining and stretch tight and only need make interference fits between the frame, the effect of fastening lining can be played in its gap shown in B, lining is not subjected to the extruding of interference fit, just impression can be do not produced, more lining can be do not injured.

The utility model is simple in structure, and is easy to use, except that the frame that stretches tight that can do to embroider, framework, indoor decoration ornaments or the oil painting framework of the commercial paper propaganda material that also can fix are practical, attractive in appearance, convenient.
