    • PROBLEM TO BE SOLVED: To connect a joint in a sealing and retaining manner by the single operation of only inserting a flexible pipe therein; to improve the sealing performance while making the joint hardly affected by deformation of the flexible pipe, bending after construction etc.; and to reduce the number of members and assembling man-hours. SOLUTION: Along with inserting a tip of the flexible pipe 2 into a socket part 3 of a joint body 5, the tip, which is inserted inside cylindrical sealing rubber 6, contacts a pipe end receptacle 6b and pushes the sealing rubber 6 into the back of the socket part. Along with the pushing, a seal acting part 6c is deformed and contracted in diameter by slide-contacting a narrower side of a first taper 15 so as to adhere tightly to at least a slant face 9a of a trough part 9 of the flexible pipe 2. An outer diameter part of a retaining projected part 6e slide-contacts a narrower side of a second taper 16 to be contracted in diameter, and an inner diameter part is fitted to another trough part 9 of the flexible pipe 2 different from the trough part 9.

    • 要解决的问题:通过仅在其中插入柔性管的单次操作来连接接头,以密封和保持方式; 提高密封性能,同时使接头几乎不受软管变形,施工后的弯曲等影响; 并减少会员人数和组装工时。 解决方案:将柔性管2的前端插入接头体5的插座部3中,插入圆筒形密封橡胶6内的端部与管端插座6b接触并推动密封橡胶6 插入插座部分的后面。 随着推动,密封作用部分6c通过滑动接触第一锥形件15的较窄侧而直径变形和收缩,以便紧密地附着到柔性管2的槽部9的至少倾斜面9a 保持突出部6e的外径部分滑动接触直径收缩的第二锥形16的较窄侧面,并且内径部分与不同于槽部分的柔性管2的另一谷部分9嵌合 9.版权所有(C)2009,JPO&INPIT
