Nearly locking level handle end is provided with limit spring；The locking level handle side of retaining mechanism main body, nearly engaging lug end are provided with limiting
Projecting block.
When connecting safety joint, retaining mechanism is pushed into fixed station by rotation lock fixed pole handle, unclamps locking level handle, lock
Fixed pole handle goes back to original position under the action of spring torsion, is rotated by limitation until touching projecting block, at this time locking level axis
Cutting portion is not contacted with fixed station, and locking level axis is in close contact with fixed station, and retaining mechanism can not be rotated and be come off, such top connection
Body is formed with lower joint body and is connected.During disconnected safety joint, rotation lock fixed pole handle, at this time locking level axis cutting portion rotate to solid
Retaining mechanism is rotated out of fixed station by Ding Tai upper surfaces, and such upper joint body can be disconnected with lower joint body.
Preferably, locking level axis both ends are respectively provided with locking level handle, are set respectively at the nearly locking level handle in locking level axis both ends
Limit spring, retaining mechanism main body both sides are equipped with, nearly engaging lug end is both provided with limiting projecting block, and locking level axis both ends are respectively provided with
When having limit spring, single locking level handle for rotating one end is not easy lock lever, and the torsion bigger that two springs provide, lock
Tight mechanism is more not easily to fall off.
Preferably, retaining mechanism main body is provided with latch closure, the latch closure can connect draw ring, to side far from engaging lug end
Just operation locking level handle.
By using above-mentioned technical proposal, meet the connector demand of common liquid conveying pipe.Large-diameter pipeline situation
Under, it can accordingly add multiple retaining mechanisms.Connector circumference sets multiple retaining mechanisms so that fittings body is in connecting pipe, lock
Tight mechanism can uniformly lock upper and lower fittings body.
Safety self locking quick connector, energy is secured under the conditions of encountering strong foreign impacts or delivered inside fluid impact
It is connected firmly, do not loosen；On the basis of ensureing that connection is reliable, and meet installation quickly requirement.
