Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments.
As shown in fig. 2-5, the present invention discloses a pull strap structure of an inflatable product, which comprises at least two plastic strips 20 arranged in parallel, wherein a plurality of threads 10 are arranged between the two plastic strips 20, and the plurality of threads 10 are located on the same plane and fixed with the plastic strips 20; each thread body 10 comprises more than two bundles of thread bundles 11, each thread bundle comprises more than two filament yarns, the width k of each thread body 10 is larger than the thread diameter d of the thread body 10 at the fixing position of each thread body 10 and the plastic strip 20.
The fixed department of line body 10 and plastic piece strip 20, line body 10 width is greater than line body 10 line footpath, shows that line body 10 is in the fixed department with plastic piece strip 20, and line body 10 has the extension in the horizontal direction, and each pencil 11 is dispersion relatively, can guarantee like this that each pencil 11 of line body 10 can contact with plastic piece strip 20 as far as possible to avoid forming obvious arch on plastic piece strip 20, also consequently solved the problem that plastic piece strip 20 easily abrades. Further, the strands 11 of the wire body 10 are dispersed only at the fixing portions with the plastic strip 20, and the strength of the other portions of the wire body 10 is not affected, so that the tensile strength of the wire body 10 can be satisfied.
In order to effectively prevent the wire 10 from forming a protrusion on the plastic strip 20, the twist degree between the strands 11 of the wire 10 is 0-50 twist/m at the fixing position of the wire 10 and the plastic strip 20. Or the width k of the line body 10 at the fixed position of the line body and the plastic strip 20 is 1.2-5.0 times of the line diameter d of the line body 10. The fixing position of the line body 10 and the plastic strip 20 is fixed by a hot melting device such as a high frequency machine or a hot press, the working frequency of the hot melting device is 10-40MHz, and the working pressure is 1kgf/cm2-100kgf/cm2。
In order to reinforce the connection strength between the wire body 10 and the plastic strip 20. The present invention also dip coats the wire body 10 in glue to form the glue layer 12. The adhesive layer 12 can be arranged in the following two ways:
as shown in fig. 3, in the first mode, the respective strands 11 of the wire body 10 are twisted, and then the twisted strands 11 are dip-coated in glue to form the adhesive layer 12, i.e., the adhesive layer 12 is coated on the twisted strands 11. At this time, the adhesive layer 12 provides a certain connection between the strands 11, so that the twist of the strands 11 can be set to 0 in this structure. Of course, if the twist of the wire harness 11 is set to be greater than 0, the connection of the wire harness 11 of the wire 10 can be strengthened, and the tensile strength of the wire 10 can be further improved.
As shown in fig. 5, in the second mode, each strand 11 is first dip-coated in glue, and then a glue layer 12 is formed on the surface of each strand, and then the strands 11 coated with the glue layer 12 are twisted to form the wire body 10. In this structure, if the twist degree is 0, the strands 11 are easily dispersed and the strength of the wire 10 is affected, so that the twist degree of the strands 11 is more than 0 in order to secure the tensile strength of the wire 10.
When the wire body 10 is connected with the plastic strip 20, the wire body 10 can be better fixed with the plastic strip 20 through the glue layer 12, thereby improving the connection stability of the wire body 10 and the plastic layer 12.
The thickness of the filament in the wire harness is 50D-2500D, and the thickness of the wire 10 is controlled within the range of 50-1000dtex. The thickness of the adhesive layer 12 is 0.01 to 0.5mm. The adhesive layer 12 may be a hot-melt adhesive (e.g. hot melt adhesive) or a volatile adhesive (e.g. PVC hard adhesive or PU adhesive).
Referring to fig. 1, in the present embodiment, the plurality of lines 10 are uniformly spaced and arranged in parallel (i.e. the lines are in an "I" shape), and the fixing positions of the lines 10 and the plastic strips 20 are fixed by the upper and lower plastic strips 20 to clamp the lines 10. As shown in fig. 6, when the drawstring structure is installed inside an inflatable product (an inflatable bed in this embodiment), the plastic film strip 20 is fixed to the inflatable product.
As shown in fig. 7, in the drawstring structure, in addition to the fixation with the wire 10 by the upper and lower plastic strips 20, the drawstring structure may also be fixed with the plastic sheet 30 by the plastic strips 20. Specifically, the plurality of wires 10 are fixed on the upper surface of the plastic sheet 30, and the plastic sheet strips 20 and the upper surface of the plastic sheet 30 are fixed to the wires 10.
As shown in fig. 8, the wire bodies 10 may be arranged in a V shape in addition to being arranged in parallel. Specifically, the plurality of line bodies 10 are connected end to form a V-shape, and the upper and lower ends of each V-shaped line body 10 are fixed to the plastic strip 20. Under the structure, the fixing with the wire body 10 can be realized through the upper and lower plastic strips 20, and the plastic sheet 30 can be connected through the plastic strips 20.
In summary, the present invention first adopts a plurality of bundles of wire harnesses 11 to form a wire body 10, and then at the fixing position of the wire body 10 and the plastic strip 20, the width of the wire body 10 is greater than the wire diameter of the wire body 10, that is, the wire body 10 extends horizontally at the fixing position, so that the wire harnesses 11 are relatively dispersed at the fixing position, thereby ensuring that each bundle of wire 11 of the wire body 10 can contact the plastic strip as much as possible, strengthening the connection between the wire body 10 and the plastic strip 20, and avoiding forming an obvious protrusion on the plastic strip 20, thereby solving the problem of easy abrasion of the plastic strip 20. Further, the strands of the wire body 10 are dispersed only at the fixing portions with the plastic strip 20, and the strength of the other portions of the wire body 10 is not affected, so that the tensile strength of the wire body 10 can be satisfied.
In addition, the adhesive layer 12 is arranged outside the wire body 10 or outside each wire bundle 11 of the wire body 10, and the adhesive layer 12 can enhance the connection strength among the multiple wire bundles 11, so that the tensile strength of the wire body 10 is further improved. Moreover, at the fixing position of the wire body 10 and the plastic strip 20, the adhesive layer 12 on the wire body 11 and the plastic strip 20 can be well fused together, so that the connection strength between the pull wire 11 and the plastic strip 20 is enhanced.
The above description is only exemplary of the present invention and is not intended to limit the technical scope of the present invention, so that any minor modifications, equivalent changes and modifications made to the above exemplary embodiments according to the technical spirit of the present invention are within the technical scope of the present invention.
