Title:
LOCK MECHANISM FOR TUBULAR BODY
Document Type and Number:
WIPO Patent Application WO/2016/021612
Kind Code:
A1
Abstract:
A lock mechanism for a tubular body, comprising: a housing having, attached to at least one end thereof, a tubular body comprising an engagement section; a lock member capable of locking and releasing the housing and the tubular body; and a ring member rotatably attached to the outer circumference of the housing and capable of moving the lock member to a lock position and a release position. The ring member comprises a locking section. The lock member is held in the release position in a state in which impelling force is accumulated in the lock member, as a result of said locking section locking to a section to be locked in the housing; and the lock member moves to the lock position together with the ring member and locks the tubular body, as a result of the tubular body being inserted into the housing, the locking section being released, and the impelling force accumulated in the lock member being released. If the ring member is slid in the axial direction of the tubular body after locking, an engaging section provided in the ring member engages with a section for engagement provided in the housing and rotation of the ring member is prevented. Therefore, the tubular body can be locked by a one-touch operation and a double-locked state can be reliably maintained and visibly confirmed.
