Title:
FITTING DEVICE ALLOWING EASY INSERTION AND SEPARATION OF PIPE AND SERVICE VALVE INCLUDING SAME
Document Type and Number:
WIPO Patent Application WO/2019/216557
Kind Code:
A1
Abstract:
The present invention relates to connection of a pipe or a tube such as a hose and, specifically, provides a fitting device used as an air cooling and heating cycle conditioning part and allowing easy insertion and separation of a pipe, and a service valve including same. To this end, the present invention provides a device structure, wherein when a pipe is inserted and separated, upper and lower grippers are rotated at 180 degrees to be folded by deviation due to a friction between each deviation bar and each deviation column, that is, a friction between an upper left-right deviation bar and an upper left-right deviation column and a friction between a lower left-right deviation bar and a lower left-right deviation column, and a circular end part of a sleeve is thus pushed by deviation, so that a tooth-end of the inner circumference of a ring lock washer spring (25) gripping (fixing) the pipe (165) is widened, and the tooth-end of the inner circumference and a contact point portion of the outer circumference of the pipe (165) are thus spaced away from each other, thereby separating the pipe. Therefore, the device structure allows the pipe (165) to be much easily and conveniently separated.
