Document Type and Number:
Japanese Patent JP2023140339
Kind Code:
A
Abstract:
To provide a joint component or the like which includes the small number of components and has simple structure, enables a flexible conduit to be changed over to a polyvinyl chloride conduit, and as a result, enables the polyvinyl conduit to be easily changed over to a steel pipe or the like.SOLUTION: A straight tubular connection portion 5, an incline portion 7 and a diametrically enlarged portion 9 are formed at a joint component 1 from one end portion toward the other end portion in this order. An end portion side of the straight tubular connection portion 5 is used as male joint structure for connection with a polyvinyl conduit. The incline portion 7 is formed in a region transiting to the enlarged portion 9 from the straight tubular connection portion 5, and the diametrically enlarged portion 9 is arranged while adjacently to the incline portion 7. A contour of a cylindrical member reaching the diametrically enlarged portion 9 from the straight tubular connection portion 5 has a cylindrical cross section which is formed at a two-stage different outside diameter. Also, by adhering a member 8 having the straight tubular connection portion and a member 12 having a female type joint structure adhere to each other directly or via a connecting member 10 in place of the joint member 1, the joint member can be used as an integrally-cylindrical joint member.SELECTED DRAWING: Figure 1
