The structure of jump ring 5 and effect, jump ring 5 is the wire spring coil structures, the circumference upper shed is the positioning ring of overcoat 4.

The structure of steel ball 6 and effect, steel ball 6 is distributed with 8 steel balls for circular steel ball commonly used at circumferencial direction, and under the effect of overcoat 4 upward forces, steel ball 6 is by fastening, thereby with external plug firm connection fast.

The structure and the effect of interior cover 7, interior cover 7 is sealed and matched by base seal ring 2 and base 1 in base 1, Returnning spring 16 is placed on the base 1, and Returnning spring 16 is within interior cover 7, Returnning spring pad 15 is connected in Returnning spring 16 away from base 1 one ends, Returnning spring pad 15 connects plug boot 8 by plug seal ring 9, be provided with jump ring 5 in interior cover 7 upper end portions, cooperate overcoat 4 in interior cover 7 outsides, cooperate intermediate portion to leave the space with interior cover 7 at overcoat 4 and cooperate outer casing spring 2, outer casing spring 2 is withstood on base 1 upper top and overcoat 4 trapezoidal positions, and overcoat 4 constitutes room assembling steel ball 6 away from the T type position of outer tiltedly structure of base 1 one end inwalls and plug boot 8.Interior cover 7 mainly contains: seal groove 71, interior cover lower end outside thread 72, positioning hole 73, annular groove 74, last discharge orifice 75, interior cover epicoele 76, interior cover cavity of resorption 77 and reseting plate 78 structures, there are 8 circular positioning holes to be periphery, are provided with reseting plate 78 structures in the positioning hole in interior cover 7 upper ends.Interior cover 7 is main members of movable members being installed and directly being matched with external plug.

The structure of plug boot 8 and effect, plug boot 8 mainly contains: discharge orifice 86, jacket wall 85 structures on following discharge orifice 81, sheath cavity of resorption 82, sheath cushion hole 87, sheath epicoele 83, the sheath.Plug boot 8 is the major parts that directly match with external plug, the main activities part that connects fast under the external plug effect.

The structure of plug seal ring 9 and effect, plug seal ring 9 is 0 RunddichtringO, is rubber material, mainly plays the effect of sealing between plug boot 8, Returnning spring pad 15 and external plug.

The structure of Returnning spring pad 15 and effect, Returnning spring pad 15 is the gasket type structure, is can obtain evenly stressed member for Returnning spring 16 when working.

The structure of Returnning spring 16 and effect, Returnning spring 16 is a coil type spring, adopts stainless steel material, and Returnning spring 16 is assemblied on the base 1, and Returnning spring 16 1 ends withstand on the cavity bottom of base 1, bear active force so that be squeezed to make at Returnning spring 16.

As shown in Figure 1, base 1 underpart is provided with base lower end screw thread 103, be mainly used to assemble the access tube of liquid, the middle chamber design is adopted on top, be convenient to assemble Returnning spring 16 in middle chamber, Returnning spring 16 adopts stainless steel material, and Returnning spring 16 is assemblied on the base 1, Returnning spring 16 1 ends withstand on the cavity bottom of base 1, bear active force so that be squeezed to make at Returnning spring 16.

Because semi-automatic rapid pipe joint is in the time spent of doing of external force manually, Returnning spring 16 pressurizeds, allow the horizontal card division of overcoat 4 internal layers be blocked and to work by jump ring 5, Returnning spring 16 is 304 stainless steel materials at stainless steel material, overlap on 7 inwalls in the both sides of Returnning spring 16 are close to, thereby Returnning spring 16 is not out of shape under extruded situation to both sides, Returnning spring 16 can not well be accepted the pressure from plug simultaneously, solves this problem so adopt at the upper end of Returnning spring 16 connection Returnning spring pad 15.

Simultaneously, be certain to leaving gap during owing to semi-automatic rapid pipe joint and the assembling of other plugs and cause the liquid water clock, so between Returnning spring pad 15 and plug boot 8, be provided with plug seal ring 9, plug boot 8 mainly is to be used for guaranteeing that other plugs insert the function that thereby 16 realizations of pressed home spring connect fast in the interior cover smoothly, when Returnning spring pad 15 is squeezed, Returnning spring 16 shortening that also can and then be squeezed, plug boot 8 is leaned on to the inside with steel ball contacting part branch, thereby can inwardly being moved, steel column is enough to allow overcoat 4 past away from base 1 motion because of the power that outer casing spring 3 provides, at overcoat 4, be provided with the chamber of assembling outer casing spring 3 between interior cover 7 and the base 1, outer casing spring 3 one ends withstand on the base 1, base 1 bears pressure, and outer casing spring 3 is put forward the thrust of enough making progress for overcoat 4 when being necessary, also be provided with base seal ring 2 in addition between interior cover 7 and base 1 and prevent leak of liquid, base seal ring 2 and plug seal ring 9 all adopt rubber-plastic foamed foam body.

When semi-automatic rapid pipe joint was not used, outer casing spring 3 was in squeezed state, and Returnning spring 16 in the raw.

When needs connect the semi-automatic rapid pipe joint of use fast, base 1 links to each other with liquid output pipe by the outside thread that is located at the lower end, the end of another pipe or shower nozzle inserts in the plug boot 8 by plug, when inserting certain depth, pin head can be pushed up on the Returnning spring pad 15, Returnning spring pad 15 stressed being delivered on the Returnning spring 16, Returnning spring 16 extrusions are shunk, thereby steel ball 6 is inwardly moved, make overcoat 4 owing to move upward smoothly until blocking under the effect of outer casing spring 3 with jump ring 5, steel ball 6 also is in inboard position and just has been stuck in the plug recess part, thereby makes the two ends of two pipes finish quick connection and sealing.

In the time need unclamping the semi-automatic rapid pipe joint that has connected, as long as it is past drop-down overcoat 4, overcoat 4 is thrown off with jump ring 5, steel ball 6 is owing to the existence of flexible force upsprings immediately, thereby unclamped the screens of steel ball 6 with the plug recess, Returnning spring 16 discharges rapidly, ejects plug fast, the inboard back taper type that adopts of the part that initially contacts with steel ball 6 on overcoat 4 tops designs, and can reduce stuck and spent phenomenon effectively and take place.

Semi-automatic rapid pipe joint is can be used for agricultural rapidly and the rapid pipe joint of the pipeline connection usefulness that gardening is irrigated, sprayed.
