摘要： A tubular joint adapted to connect a pair of pipes is formed by a joint body made of a synthetic resin having a pair of connection ports integrally formed on respective sides thereof. An engaging groove is formed around an axial line on an outside circumferential surface of each of the connection ports, and a synthetic resin-made fall-out preventing member is fixed at an end portion of each of the connection ports. An outside cylindrical portion of each of the fall-out preventing members has a tapered surface adapted to enable the fall-out preventing members to be press-fitted onto the respective connection ports, and includes a plurality of engaging portions that are engaged with the engaging groove formed around the axial line on the outside circumferential surface of each of the connection ports as the fall-out preventing members are press-fitted thereon. And an inside cylindrical portion of each of the fall-out preventing members extends toward a center of the connection ports in an inclined manner, and includes a plurality of fall-out stoppers whose tip ends are shaped so as to be engaged in a groove portion formed around an axial line on the outside circumferential surface of the respective pipes to be connected as the pipes are inserted and fitted in the connection ports.

摘要： A cable chain having a number of chain unit members made of synthetic resin, wherein each of the chain unit members includes a supporting plate for mutually connecting together a pair of side plates opposite each other at an appointed interval and side plates opposite each other at both ends of the supporting plate at a lower portion thereof. A covering member made of synthetic resin covers an upper opening of the respective chain unit members, and a hinge member is provided which is made of synthetic resin having an integral hinge property. The hinge member is molded in advance to be a plate-like member having an engaging portion to be engaged in an attaching hole secured at the respective supporting plates of adjacent chain unit members, or is welded to and linked with the respective supporting plates of adjacent chain unit members by injection.

摘要： A tubular joint including at least a pair of connection ports having an inner diameter substantially equivalent to an outer diameter of tubes to be connected, and a tubular connection part connecting the connection ports to each other. The connection ports each have a sealing member formed integrally thereon by extruding elastomer resin into a first recess formed around an axial line on an inner circumferential face of the connection ports, and the connection ports each have a fall-out preventing member coupled to an end part of the connection ports. The fall-out preventing member includes a ring-like member having an outer diameter sized for insertion into the connection ports, and a number of claws having leading edges located in a second recess formed around the axial line on the inner circumferential face of the connection ports and extending toward a center of the connection ports. When a tube is inserted into one of the connection ports, the claws slidably contact an outer circumferential face of the tube and are elastically deformed in a diameter-swelling direction to thereby enable insertion of the tube, whereupon the claws are brought into contact with the outer circumferential face of the tube due to an elasticity return pressure to thereby prevent the inserted tube from falling out of the one of the connection ports. At the same time, the sealing member is simultaneously brought into contact with the outer circumferential face of the inserted tube to thereby achieve an airtight coupling between the inserted tube and the one of the connection ports.
摘要翻译：一种管状接头，包括至少一对连接口，所述至少一对连接端口的内径基本上等于要连接的管的外径，以及将连接端口彼此连接的管状连接部件。连接口各自具有通过将弹性体树脂挤出到在连接端口的内周面上形成在轴线周围的第一凹部中而一体地形成的密封构件，并且连接端口各自具有联接到端部的防脱落构件部分连接端口。防脱出构件包括具有尺寸适于插入连接端口的外径的环状构件，以及多个爪，其具有位于连接件的内周面上的围绕轴线的第二凹部中的前缘端口并延伸到连接端口的中心。当管插入到一个连接端口中时，爪可滑动地接触管的外周面并且在直径膨胀方向上弹性变形，从而能够插入管，于是爪与其接触由于弹性返回压力而导致管的外圆周面，从而防止插入的管从连接端口中脱出。同时，密封构件同时与插入管的外周面接触，从而实现插入管与连接口之一之间的气密耦合。
