One, technical field:

The utility model relates to fast connector, what be specifically related to is pressure release fast connector in the anti-leak.

Two, background technique:

Mostly the fast connector that uses is have internal thread to constitute by the two ends design of adapter sleeve now, and fast connector couples together two pipes by the screw thread at two ends.But owing to often retain in the pipe that will connect medium is arranged, this part medium exists pressure, when using used fast connector to connect, medium is just emerged outside the pipe in the pipe, or even ejects, and splashes on people's the body or facial, befouling environment not only, but also may damage human body.

Three, summary of the invention:

The purpose of this utility model provides pressure release fast connector in a kind of anti-leak, and medium leaked or the problem of spray outward when the pressure release fast connector was used to solve existing fast connector two pipes are coupled together in this anti-leak.

The technological scheme that its technical problem that solves the utility model adopts is: the pressure release fast connector is formed by connecting body and connection-peg in this anti-leak, connect in the body Decompression valves is arranged, connect body and also be provided with locking device, the connection-peg outer installment has seal ring and locking slot; Connection-peg inserts in the locking device that connects body, and withstands on the Decompression valves.

Decompression valves is made of spool, limit spring, spring seat, sealing gasket, pressure release spring in the such scheme, spring seat is installed on the spool, the pressure release spring is installed between spring seat and the valve core case, valve core case has axial hole, limit spring mounts elastically, between spring seat and the pressure release spring sealing gasket is installed, limit spring, spring seat, sealing gasket are limited in the pressure release valve pocket.

Decompression valves is made of spool, limit spring, spring seat, sealing gasket, pressure release spring in the such scheme, spring seat is installed on the spool, the pressure release spring is installed between spring seat and the valve core case, valve core case is " ten " word shape, limit spring mounts elastically, between spring seat and the pressure release spring sealing gasket is installed, limit spring, spring seat, sealing gasket are limited in the pressure release valve pocket.

Locking device in the such scheme includes snap ring, ball, lock tube, spring, ball is movably arranged in the openwork hole of the annular space that connects the body right end portion, engaging is arranged on the right-hand member that is connected body to lock tube with spring by snap ring, and ball is corresponding with the locking slot of connection-peg.

Beneficial effect:

1, connection-peg of the present utility model inserts when connecting body, the seal ring of connection-peg promptly comes into effect sealing, prevent to produce and leak, when connection-peg marches forward again, the pressure release spring pressurized retraction of Decompression valves, locking device pins connection-peg with being connected body simultaneously, finishes the connection between the tube and tube, and it is very convenient, rapid to operate; In this connection procedure,, the pressure in the connected tube is released, has avoided environmental pollution that spray caused outside medium leaked in the pipe and the injury that may cause human body owing to pressure release spring retraction.

2, the utility model is of many uses, can be applicable to the connection between the oil pipe, the connection between the water pipe, the connection between the fire-fighting band.

Five, embodiment:

Below in conjunction with accompanying drawing the utility model is described further:

In conjunction with Fig. 1, Fig. 2, shown in Figure 3, the pressure release fast connector is formed by connecting body 1 and connection-peg 2 in this anti-leak, the left end that connects body 1 has internal thread 15, there is a pressure release valve pocket 10 that is separated into by two annular boss the intermediate portion, be placed with Decompression valves in the chamber, the right-hand member that connects body 1 is provided with locking device.The outside of connection-peg 2 is disposed with the locking slot 4 of a three seals ring 3 and an annular, connection-peg 2 inserts in the locking device that connects body 1, withstand on the Decompression valves, when connecting body 1 with connection-peg 2 pinnings, the ball 12 of locking device enters in the locking slot 4 of connection-peg 2 just, pressure release spring 9 pressurizeds retraction; The right-hand member of connection-peg 2 has internal thread 16.

Decompression valves is by spool 5, limit spring 6, spring seat 7, sealing gasket 8, pressure release spring 9 constitutes, spring seat 7 is installed on the spool 5, pressure release spring 9 is installed between spring seat 7 and the valve core case, valve core case has axial hole, limit spring 6 is installed on the spring seat 7, sealing gasket 8 is installed between spring seat 7 and the pressure release spring 9, as shown in Figure 2, when connection-peg 2 did not insert connection body 1, Decompression valves was in free state, at this moment, pressure release spring 9 is positioned at the locking device position, but limit spring 6, spring seat 7, sealing gasket 8 is limited in the pressure release valve pocket 10 by two annular boss, and wherein sealing gasket 8 is close together with the boss on its right side, plays seal action.

Locking device includes snap ring 11, ball 12, lock tube 13, spring 14, and ball 12 is movably arranged in the openwork hole of the annular space that connects body 1 right end portion, and lock tube 13 is spacing by snap ring 11 and spring 14, and ball 12 is corresponding with the locking slot 4 of connection-peg 2.After connection-peg 2 inserted and connects body 1, locking device pinned the two, and when needs separated the two, by axial promotion lock tube 13, ball 12 no longer was in spacing state, and locking device is opened, and connection-peg 2 can be pulled out.

Connection-peg 2 of the present utility model inserts when connecting body 1, and two road seal rings 3 of connection-peg 2 promptly come into effect sealing; When connection-peg 2 marches forward again, pressure release spring 9 pressurizeds of Decompression valves bounce back in the pressure release valve pocket 10, medium flows through from the axial hole of valve core case, simultaneously locking device with connection-peg 2 be connected body 1 pinning, finish the connection between the tube and tube, at this moment, because pressure release spring 9 retractions, pressure in the connected tube is released, spray outside medium leaks in having avoided managing.As can be seen, the utility model is when connecting two pipes, and sealing, pressure release, locking is instantaneous finishes, and it is very convenient, rapid to operate.

Fig. 4 provides the structural representation of second kind of mode of execution of the utility model, the difference of pressure release fast connector is in the anti-leak that pressure release fast connector and Fig. 1 provide in this anti-leak, consult Fig. 5, Fig. 6, the valve core case of Decompression valves is " ten " word shape, when connection-peg 2 inserts connection body 1 and locks together, connection-peg 2 withstands on the valve core case of " ten " word shape, the circumferential surface of the connection-peg 2 that valve core case will contact with it is separated into four parts, and medium flows through from four gaps of valve core case through connection-peg 2.Other structure is identical with first kind of mode of execution shown in Figure 1.
