Abstract

A kind of elastic band location structure is the utility model is related to, mainly：It will weave vertically to elastic tree lace, the horizontal baseline of yarn, it is set as mutually being twisted as one by two baselines, overall lines are made to form the concave, convex face continuously to rise and fall, rather than smooth straight line, therefore, the baseline being constructed so as to can have the function that the fixed elastic tree lace of resistance, yarn, when external force, which is dialled, touches elastic tree lace, yarn, can have and prevent elastic tree lace, the effect of yarn slippage displacement, integrality except overall lines decorative pattern can be kept, normal stretching, convergent force can be more kept, makes elastic band positioning good and there is more preferably practical effect.

Description

Elastic band location structure

Technical field

A kind of elastic band location structure is the utility model is related to, it has the elastic tree lace of elastic band to be positioned at baseline and stretch Contracting, can not slide displacement the effect of.

Background technology

Existing structural elastic, substantially all as shown in Figure 1 and Figure 2, the horizontal baseline 10 of a setting width, the baseline 10 That non-telescoping nylon wire is formed, in baseline 10 weave it is a plurality of be in a strip sheet region elastic tree lace 11, each elastic gum Line 11 is concentrated closing and formed in Extensible and the yarn 12 of winding one or more, plurality of yarns 12, elastic tree lace 11 The rib L of strip sheet, elastic tree lace 11, yarn 12 are telescopic region, form the effect of elastic band；Above-mentioned knot Structure, exist in fact and have the disadvantage that：

(1) shown in W positions as shown in Figure 1, Figure 2, it can stir elastic tree lace 11, yarn 12 and displacement, reason because of external force：Its Baseline 10 is the linearly smooth shape of nylon material and an only baseline 10, baseline 10 are without hindrance fixed to elastic tree lace 11, yarn 12 Effect, therefore elastic tree lace 11, the slidably displacement of yarn 12, cause displacement deformation W phenomenon, influence complete attractive in appearance.

(2) also, " displacement deformation W " can impact being averaged for convergent force.

Utility model content

The purpose of this utility model is to improve above-mentioned " the problem of displacement deformation W " in the prior art.

For the above-mentioned purpose, the utility model provides a kind of elastic band location structure, and longitudinal elastic tree lace is knitted to horizontal stroke To baseline, the baseline, which is set as the baseline of two, mutually to be twisted with the fingers to twine and integrally combines, and being formed when two twisted baselines are twisted has Concave surface that whole piece continuously rises and falls, convex surface, when elastic tree lace is knitted to the baseline, concave surface, the convex surface of baseline can have jam bullet Property tree lace effect, and with prevent elastic tree lace slide displacement the effect of.

Foregoing elastic band location structure, wherein, the baseline can be set as more than two mutually twisted one.

Foregoing elastic band location structure, wherein, two baselines can be twisted together a hot melt adhesive line simultaneously when twisted, add Melt hot melt adhesive line after heat, and then bond two twisted baselines and close.

Foregoing elastic band location structure, wherein, two baselines, which can apply stick when twisted simultaneously and bond, to be closed.

The beneficial effects of the utility model：It is integrated if baseline is set as into two or more and mutually twists with the fingers entanglement, shape The concave, convex face to be risen and fallen into whole piece, in other words, it is in the smooth shape of non-rectilinear to make baseline, when elastic tree lace, yarn are knitted to baseline, There can be the effect of the fixed elastic tree lace of resistance, yarn by the structure of concave, convex, reaching prevents elastic tree lace, yarn displacement from deforming Effect, it is ensured that the convergent force complete attractive in appearance and normal of overall rib.

Embodiment

Fig. 3, Fig. 4 are referred to, longitudinal a plurality of elastic tree lace 22 has yarn 23, and elastic tree lace 22, yarn 23 are knitted to Horizontal a plurality of baseline 20,21；The baseline 20,21 is set as the mutually sth. made by twisting entanglement of two or more baseline 20,21 and is combined into one Body, concave surface 201, the convex surface 202 continuously to be risen and fallen with whole piece is formed when two or more baseline 20,21 is twisted, makes base Line 20,21 is in Non-smooth surface shape.

By above-mentioned structure, can have following effect, advantage：Elastic tree lace 22, yarn 23 are knitted to baseline 20,21 When, concave surface 201, the convex surface 202 of baseline 20,21 can form jam elasticity tree lace 22, the effect of yarn 23, therefore can prevent elasticity Tree lace 22, the displacement of yarn 23, it is the rib flexural deformation that elastic tree lace 22, yarn 23 can be prevented to be formed.Thereby, it is ensured that Elastic tree lace 22, yarn 23 are linearly, do not bend, and are able to ensure that the flexible convergent force of elastic tree lace 22.

The utility model can also be implemented to be in glue again after two baselines 20,21 are twisted together in terms of twisted two baseline 20,21 Integrally combine.It bonds the mode closed and can used：(1) stick bonding is applied simultaneously when twisting with the fingers and combining；(2) as shown in Figure 5, Figure 6, At twisted two baseline 20,21, while a hot melt adhesive line 24 (also known as thermal melting wire) is twisted together again, give heating, hot melt adhesive line 24 can Melt and two baselines 20,21 are bonded and closed.
