Description

Self-closing lock quick connector and anti-dropout Quick insertion connector
Technical field
The present invention relates to connection area more particularly to a kind of pipeline connection-pegs, and in particular to a kind of quick grafting of Self-closing lock Head and anti-dropout Quick insertion connector, can be used for two sides has in the self-closing locking device of fluid hose of pressure difference, to prevent letting out for fluid Dew and refluence;The especially useful anti-connection-peg of metalling run out for making washing machine feed pipe.
Background technique
Quick coupling is that a kind of tool that do not need can be achieved with the connector of pipeline connection or disconnection.Quick coupling generally by Latching connector as parent and the connection-peg composition as daughter, connection-peg inject in latching connector.When pulling out connection-peg, easily Fluid leakage is caused, safety accident is caused.
Existing washing machine inlet hose is plastic flexible pipe, and hydraulic pressure slightly increases in use, and joint just loosens or even falls off.It is existing Automatic washing machine is used in most family, wage-earners, is connected on tap always for feed pipe easy to use.Once water supply Pipe fitting falls off, and tap water, which will be gushed out, to be caused to metal run out.Light then floor is fallen off by bubble deformation, metope wall skin, heavy then water enters cloth If electrical socket on the wall causes bigger accident.In the city that high buildings and large mansions stand in great numbers, a family, which is metalled run out, often brings disaster to resident downstairs. How to prevent from washing machine inlet hose from falling off from tap to have become washing machine and need the technical issues of focusing on solving in.
Chinese patent ZL91205052 discloses a kind of anti-dropping water inlet hose connector for washing machine, with soft water pipe from originally When tap upper accepting water, water receiving pipe horn mouth is inserted on tap, velcro fastener is then bypassed into tap root, after tension It sticks together with velcro fastener, it is ensured that water supply hose is not fallen off.The structure is needed when processing soft water pipe horn mouth, is reserved with Then two protrusion parts upwardly extended in parallel are sewed up nylon tape on protrusion part, are sewed in the inside top of nylon tape Velcro fastener flanks velcro fastener in protrusion the outer of part.There are some problems for this structure, and it is not firm enough to connect, and is still easy Infiltration leak;Main is that its plugging position does not just have Self-closing lock sealing device at all, falls or relaxes once plugging off fastly, infiltration of metalling run out Water is also just inevitable.
For convenience of description, above by taking washing machine as an example, but those skilled in the art knows, quick coupling more application In many fluid circuits of the both ends there are pressure difference.Therefore, a kind of Self-closing lock for preventing fluid leakage and refluence is designed to insert fastly Connector becomes field of pipeline connection a problem to be solved.
