Annular drawstring for inflatable product and manufacturing method of annular drawstring
The annular drawstring comprises an uninterrupted line body and a plastic sheet film, the line body is spirally wound and woven in the axial direction to form a line ring, the plastic sheet film is arranged in the line ring in the direction parallel to the winding axis of the line body, and the plastic sheet film and the upper line body and the lower line body of the line ring are fixed to form an upper drawstring fixing face and a lower drawstring fixing face. The left line body and the right line body of the line ring form a left drawstring stretching face and a right drawstring stretching face, and the annular drawstring is fixed to the inner wall of an inflation cavity in an inflation product through the drawstring fixing face. The inflatable product is formed by spirally winding and weaving the uninterrupted line body, is light in weight, convenient to transport and low in production cost, has high tensile strength, can bear large tensile force and is not prone to deformation caused by laddering under the condition of uneven stress, and the service life of the inflatable product is prolonged.
本发明公开了一种环形拉带及应用的充气产品，包括一根不间断的线体和塑胶片膜，所述线体沿一轴向螺旋式绕织形成线环，所述塑胶片膜平行线体绕轴方向设置在线环内，并与所述线环的上、下线体固定形成上、下拉带固定面，所述线环的左、右线体形成左、右拉带拉伸面，该环形拉带通过所述拉带固定面固定在充气产品内部的充气腔内壁上。本发明由一根不间断的线体螺旋绕织而成，重量轻便，方便运输，生产成本低，具有较高的抗拉伸强度，能够承受较大的拉力，在受力不均情况下都不易抽丝而变形，延长了充气产品的使用寿命。
