摘要: A tubular-member lock mechanism includes a cylindrical housing to which a tubular member having an engagement portion at one end is mounted, and a lock member for engaging or releasing the housing and the tubular member. The housing includes a lock-member guide wall turnably guiding the lock member, at least two sliding surfaces with different inclinations wherein a tip portion of the lock member slides by turning the lock member, and a slit through which one portion of the lock member passes to engage the engagement portion of the tubular member mounted to the housing. The lock member, at a standby/lock position, engages the engagement portion formed on an outer periphery of the tubular member, and the lock member, at a release position where a rotational load is applied, spreads by the sliding surfaces having the different inclinations releases the engagement portion of the tubular member.

摘要: A rotate-to-press inflation adaptor is provided for use with an English valve and includes a valve connector having a side surface recessed inwardly to form a positioning cavity having an inside surface in which slide channels are formed and two opposite ends respectively forming a valve opening and a coupler opening in communication with the positioning cavity. The coupler includes an air charging hole extending axially therethrough and an outer surface on which an external thread and two slide blocks are formed for being slidably received in the slide channels for reciprocal movement. The rotary knob has a through hole in which an internal thread is formed and the knob body is fit over and combinable with the valve connector in a rotatable manner with the internal and external threads engaging each other. An air tube is connected to the coupler.

摘要: In a rapid coupling, a pipe nipple engages a through hole of a socket. A first annular groove provided on the pipe nipple serves to catch a locking ring provided in the socket, in order to lock the coupled condition. A sleeve is movable on the pipe nipple, the sleeve having an inner projection to be retained by the first annular groove of the pipe nipple in a pre-assembled condition. When the pipe nipple is inserted into the socket, the sleeve abuts the socket and is then moved along the pipe nipple until the inner projection is caught by a second annular groove if the coupling is properly locked. It the pipe nipple is not moved into the socket to such an extent that the locking ring is caught by the first annular groove, the second annular groove remains visible outside the sleeve to indicate the improper coupling condition.

摘要: A latching or release mechanism in which the insertion force can be different from the removal force. Furthermore, the said latching or release mechanism will automatically release upon applied removal force. The latching or release mechanism additionally can be readily adapted for use as a fluid coupler or as a pass-through latch.

摘要: A rapid-connect gas coupler is shown and described herein. In an embodiment, the rapid-connect gas coupler includes a spring-loaded probe within a probe cavity, which is defined by a housing and one or more latch segment. The probe can engage with a gas connector, which causes the latch segment to engage and couple with the gas connector.

摘要: A lock mechanism of a tubular body includes a housing to which a tubular body is mounted, a lock member locking and unlocking the housing and the tubular body, and a ring member rotatably attached on an outer periphery of the housing and moving the lock member between a lock position and an unlock position. When a locking portion of the lock member is locked to a locked portion of the housing, the lock member is retained in the unlock position. When the tubular body is inserted in the housing to unlock the locking portion and release an urging force accumulated in the lock member, the lock member moves to the lock position together with the ring member to lock the tubular body. When the ring member is slid in an axis direction of the tubular body after being locked, the tubular body can be locked with one touch.

摘要: A fuel line connector assembly that includes first and second connectors. The first connector includes a ramp having an inner core and an outer skin surrounding at least a part of the inner core. The inner core extends through the ramp at a location adjacent a radially extending retaining surface for at least a portion of the radial extent of the retaining surface. The second connector has a hook wherein, when the first and second connectors are brought together and secured to each other, the hook inhibits separation of the first and second connectors by bearing again the retaining surface. The first connector is made by coinjection molding a connector body having the outer skin and inner core with the inner core extending through the ramp to a sacrificial portion, and then severing the sacrificial portion from the ramp leaving the inner core exposed at an apex of the ramp.
