Description

Elastic string band

Technical field

The utility model is related to rope band field, more particularly to a kind of elastic string band.

Background technology

Since in our daily lifes, some objects such as shoes, clothing, cap, sack and waistband etc. can use and arrive rope band Make it is regular link closely or unclamp operation, this mode is generally applied, and these objects would generally be equipped with opening or eyelet The perforation of class, for wearing for the rope band, the knotting system for finally penetrating the rope band both ends again ties up, to reach behaviour that is fixed and folding Make.

Since the rope sling is not to be made of elastic material, thus its flexible ability is limited, directly limitation should can arrive the bullet Property the protractile range of wire rope core, and the elasticity wire rope core itself exists simultaneously flexible and hardly flexible part, causes to use Inconvenient problem.

Utility model content

The purpose of this utility model is to provide a kind of elastic string band, with stroke appropriate to adapt to actual use Advantage.

The above-mentioned technical purpose of the utility model technical scheme is that：

A kind of elastic string band, the rope yarn being twisted together with multifilament, and it is twisted together into rope strand with more rope yarns, then with more rope strands Synthetic rope is twisted, more rope yarns are twisted together into rope strand and are arranged in hollow form, during which keeps identical along its length Empty shape, and it is equipped at intervals with multiple protrusions along its length on the inner periphery of the rope strand；

The hollow inside of the rope strand is filled with is made bullet by any one elastic foam in TPR or EVA or EPDM Property layer, between the elastic layer and the inner periphery of rope strand be equipped with high-obstruction.

Further, the high-obstruction is that EVOH films or PVDC films, PAN films, MXD6 films are wherein any one Kind film or multiple combinations film.

Further, the protrusion is distributed in the shape of a spiral along the length direction of rope strand.

Further, the raised length direction equidistantly distributed multirow along rope strand, and circle distribution multiple row.

Further, the protrusion is being arranged for mix mode, includes that two or more different prominent shapes form Protrusion.

Further, the shape of the protrusion is an asymmetrical type shape.

Further, the shape of the protrusion is a symmetric form shape.

In conclusion the utility model has the advantages that：1, using above-mentioned rope strand, inner hollow is arranged, The rope that the twisted rope strand of more rope strands is twisted together again have it is several carry hollow rope strand, rope has stronger flexural deformation energy Power；Due to being internally provided with multiple protrusions in hollow rope strand, raised spherical surface can mutually contradict the effect for generating elastic buffer, On the one hand the elastic force for providing bending, on the other hand provides restoring force after bending；

2, using buffer layer made of elastic foam, there is the elasticity of plasticity at normal temperatures using it so that ribbon sheet Body has certain flexibility and support strength, not only can ensure due tear-strength when extract in use, but also It may insure enough elastic-restoring forces.

Description of the drawings

Fig. 1 is a kind of structural schematic diagram of elastic string band.

In figure, 1, double six monofilament of nylon；2, raised；3, rope yarn；4, rope strand；5, rope；6, elasticity is made in elastic foam Layer；7, high-obstruction.

Specific implementation mode

The utility model is described in further detail below in conjunction with attached drawing.

Embodiment 1：A kind of elastic string band, as shown in Figure 1, the rope yarn 3 being twisted together with multifilament, and twisted with more rope yarns 3 Rope strand 4 is synthesized, then synthetic rope 5 is twisted with more rope strands 4, the monofilament for constituting rope yarn 3 is double six monofilament 1 of nylon.

More rope yarns 3 are twisted together into rope strand 4 and are arranged in hollow form, during which keeps identical along its length Empty shape, rope strand 4 can enable rope strand 4 to keep hollow form during twisted by certain flexible plastic molding State, 4 centre of rope strand keep identical hollow shape along its length, and on the inner periphery of the rope strand 4 along its length between Every equipped with multiple raised 2, protrusion 2 is spherical, and protrusion 2 is all plastic cement, during plastic molding, is formed using its plastic cement multiple Protrusion 2.

In order to promote elastic effect, filled with by any one in TPR or EVA or EPDM inside 4 center hollow of rope strand Elastic layer 6 is made in kind elastic foam, and high-obstruction 7 is equipped between the elastic layer and the inner periphery of rope strand 4.High-obstruction 7 is EVOH films or PVDC films, PAN films, MXD6 film any of which films or multiple combinations film.It is hindered by film Every elastic layer, facilitate elastic layer can be in 7 inside plastotype of high-obstruction.

Protrusion 2 is distributed in the shape of a spiral along the length direction of rope strand 4.Spiral distribution makes protrusion 2 in the inner periphery of rope strand 4 On, the protrusion 2 in opposite mutually contradicts, and when rope strand 4 is bent by external force, protrusion 2 is logical in the state of mutual squeeze Elasticity is crossed so that there is rope strand 4 restoring force, guarantee rope strand 4 can be bent and can restore, permanency shape.

Protrusion 2 is arranged for mix mode, includes that two or more differences protrude the protrusions 2 that shapes form, and protrusion 2 Shape be an asymmetrical type shape.For example it is spheroid shape.It is stronger that the shape difference of protrusion 2 so that elasticity moulds ability, makes Used time, the elastic force in all directions is different, adapts to situation irregular curved in actual use.

Embodiment 2：A kind of elastic string band, difference from example 1 is that, the shape of protrusion 2 is a symmetric form shape Shape, for example be ball-shaped.

Embodiment 3：A kind of elastic string band, difference from example 1 is that, length direction etc. of the protrusion 2 along rope strand 4 Spacing is distributed multirow, and circle distribution multiple row.

The above embodiments are only the explanation to the utility model, are not limitations of the present invention, ability Field technique personnel can as needed make the present embodiment the modification of not creative contribution after reading this specification, but As long as all being protected by Patent Law in the right of the utility model.
