Embodiment
Further understand and be familiar with for making structure characteristic of the present invention and the effect reached had, cooperate detailed explanation in order to preferred embodiment and accompanying drawing, be described as follows:
Such as Fig. 1, Fig. 2, shown in Figure 3, a kind of safe self-locking rapid pipe joint, comprise connect soon overcoat 1 and and connecting screw 2, be provided with inner sleeve 3 at the inwall that connects soon overcoat, in put and be set with the first spring 4, connecing soon overcoat 1 relatively moves vertically with inner sleeve 3, as improvement of the present invention, be provided with ball valve 5 connecing soon between overcoat 1 and the connecting screw 2, one end and the inner sleeve 3 of ball valve 5 are tightly connected, the other end of ball valve 5 is tightly connected by seal arrangement 6 and connecting screw 2, also is provided with self-locking device 7 in inner sleeve.
The both sides of inner sleeve 3 are provided with the flange that radially extends, self-locking device 7 is fastened between two flanges, self-locking device comprises jump ring 71, lining 72, piston sleeve 73, the second spring 74 and steel ball 75, jump ring 71 is sleeved on a side of lining 72, the opposite side of lining 72 and piston sleeve 73 are tightly connected, the opposite side of piston sleeve 73 is set with the second spring 74, the second spring 74 contacts with the flange of inner sleeve 3, inner sleeve 3 is provided with a through hole, steel ball 75 is arranged in this through hole, the top of steel ball 75 contacts with the inwall that connects soon overcoat 1, and the below of steel ball 75 contacts with the outer surface of lining 72.
Seal arrangement 6 comprises spool 61, seal rubber sleeve 62 and the 3rd spring 63, one end of spool 61 is connected with ball valve 5 by seal rubber sleeve 62, seal rubber sleeve 62 contacts with the surface extruding of the spheroid 52 of ball valve, the other end of spool 61 is provided with bead, one end of the 3rd spring 63 is sleeved on this bead, and the other end of the 3rd spring 63 contacts with the inwall of connecting screw 2.
When rotating trigger, when trigger 53 is corresponding with a side that connects soon overcoat 1 place, ball valve 5 is in opening state, gas enters through ball valve 5 from inner sleeve 3, flow out from connecting screw 2 outlet ports at last, before ventilation, axially can relatively move owing to connect overcoat 1 and inner sleeve 3 soon, after the ventilation, directly with hand propulsion village cover 72 compressions the second spring 74, allow steel ball 75 slide in the lock pin groove automatic locking, leave axial clearance owing to connect soon a side of overcoat 1 and ball valve 5, overcoat 1 is still can be back and forth movable, and lock pin can eject along with the activity of overcoat 1, so do not reach safe effect, but in this case, trigger 53 has played safe effect and since trigger 53 when corresponding with a side that connects soon overcoat 1 place for ventilating, so trigger 53 withstands and connects soon overcoat 1 at work, connecing soon overcoat 1 can be unmovable, reaches safe effect.
During medium mobile, only need to rotate trigger 53 and make trigger corresponding with a side at connecting screw 2 places in needs cut off rapid pipe joint, the spheroid 52 in the ball valve rotates 180 and spends, and ball valve 5 is in closed condition.This product surface is electropolishing, gives the people visually very generous.
Among the present invention, at the inlet end that connects soon overcoat 1 lid 8 can also be set, when rapid pipe joint does not need to use, cover tightly lid 8 and get final product.
More than show and described basic principle of the present invention, major character and advantage of the present invention.The technician of the industry should understand; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and the specification is principle of the present invention; the present invention also has various changes and modifications without departing from the spirit and scope of the present invention, and these changes and improvements all fall in the claimed scope of the present invention.The protection domain that the present invention requires is defined by appending claims and equivalent thereof.
