Title:
TUBULAR-BODY LOCK MECHANISM
Document Type and Number:
WIPO Patent Application WO/2015/141557
Kind Code:
A1
Abstract:
The present invention is a tubular-body lock mechanism comprising a housing, to which a tubular body is mounted, and lock member that can engage and release the housing and the tubular body, wherein the housing is provided with: a lock member guide wall that guides the lock member; a sliding surface that is at least two sliding surfaces at which the tip of the lock member slides and having differing inclinations; and a slit through which a portion of the lock member passes and that has a shape for engaging the tubular body. The lock member can engage an engagement section formed at the outer periphery of the tubular body by means of elastic force at a standby/locked position, at the release position at which a rotational load is applied, the lock member is spread by the sliding surfaces having differing inclinations from each other, causing a release from the engagement section of the tubular body, and so it is possible to connect/lock merely by mounting the tubular body and unlocking is easily possible with light force.
