Description
Technical field
The invention belongs to the fast plug technical fields of mechanical equipment, are related to a kind of self-locking fast plug, in particular to one kind is suitable for
Mechanical equipment tracheae or liquid pipe insert the self-locking fast plug of connection fastly.
Background technique
In mechanical equipment, quick connector is the most simply and easily attachment device of plug and play, especially in gas
Or liquid transmission connection inconvenience can more embody the superiority of quick connector, have even under relatively difficult space situations
Have the advantages that applied widely and at low cost.
As shown in Figure 1, traditional quick connector, including plastic housing body 1, disengaging ring 4, metallic sheath 2 and claw 3, wherein being detached from
The structure of ring and metallic sheath difference is as shown in Figures 2 and 3, and after the insertion of pipe 5, umbrella claw opens naturally forms hangnail card
Firmly pipe prevents pipe from falling off, and umbrella claw opened again and is open greater than tube outer diameter, pipe when pressing is detached from ring
It can easily extract.
There is no limiting device since traditional fast plug is detached from ring, places one's entire reliance upon and be detached from the intrinsic elasticity of ring and claw to limit
The displacement of tubulation, when external force is detached from ring, claw rotary table will be squeezed by being detached from ring cylinder a 6, due to empty in mechanical equipment
Between it is narrow, when multiple fast interpolating unit parts squeeze when, pipe be easy bending, internal tube pressure is higher, mechanical equipment and quick connector
Active force is bigger between pipe, is more likely to cause and is detached from ring and is extruded so that pipe falls off, ultimately cause mechanical equipment or
The production accident of product, there are larger security risks.
Therefore, a kind of self-locking fast plug for being not easy that pipe is made to fall off is studied to have a very important significance.
Summary of the invention
