    • 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

    • PROBLEM TO BE SOLVED: To provide a flexible pipe joint for preventing a failure in inserting a pressing ring. SOLUTION: The flexible pipe joint 10 includes a joint body 20 and the pressing ring 24. The pressing ring 24 has a cylinder portion 76a, and an exposed portion 76b. Through the cylinder portion 76a, a flexible pipe 300 passes. The cylinder portion 76a is pushed through an insertion port 30 into the joint body 20. The exposed portion 76b is provided on the rear side of the cylinder portion 76a, and exposed to the outside of the joint body 20 even after the cylinder portion 76a is pushed into the joint body 20. The cylinder portion 76a of the pressing ring 24 has a to-be-fitted portion 77. The to-be-fitted portion 77 is inserted into the joint body 20 at its midway and held in the state that it is not completely inserted into the joint body 20. Onto the outer peripheral face of the to-be-fitted portion 77, a color is applied which is different at least from that onto each of the outer peripheral face of the joint body 20 and the outer peripheral face of the exposed portion 76b.
