Embodiment
Below in conjunction with Figure of description and embodiment, specific embodiment of the utility model is described in further detail:
Referring to figs. 1 through a kind of air pump Quick joint for pipeline shown in Fig. 3, comprise outer silk nut 1, joint maincenter 2, joint overcoat 3 and joint spool 4; Air chamber 1a is provided with in described outer silk nut 1; Described joint maincenter 2 one end is provided with the threaded ends with outer silk nut 1 screw-thread fit, and the other end is provided with the screw cap end for tightening joint maincenter 2; Described joint overcoat 3 is sheathed between the screw cap end of joint maincenter 2 and outer silk nut 1 movably; Described joint overcoat 3 inwall is provided with to projecting inward limited ring 3a, and the side of this limited ring 3a silk nut 1 is toward the outside provided with the outer casing spring 5 be sheathed between joint overcoat 3 and joint maincenter 2; Described joint maincenter 2 is folded with rubbery flat gasket 6 with the joint of outer silk nut 1; Described joint spool 4 plugs with in this rubbery flat gasket 6; Be provided with spacing back-up ring 4a outside described joint spool 4, the side of this spacing back-up ring 4a props up the end of rubbery flat gasket 6, and opposite side withstands the bottom of air chamber 1a by a volute spring 7; The sidewall of described joint maincenter 2 near screw cap end side is along the circumferential direction evenly provided with several cone shape holes, is equiped with a steel ball 8 in each cone shape hole; The inwall of described steel ball 8 along joint maincenter 2 radial direction against joint overcoat 3 upper limit ring 3a.
The threaded ends of described joint maincenter 2 is provided with the deep gouge for installing rubbery flat gasket 6.
Described joint finds to be provided with the open end of the closed end that offsets with volute spring 7 and the screw cap end towards joint maincenter 2; Described joint spool 4 is provided with the suction chamber 4b extended along open end to closed end, and the sidewall of this suction chamber 4b is provided with suction port 4c.
The utility model decreases the seal ring arranged between each movable part in traditional rapid pipe joint, therefore circular groove pivot 2 inwall and joint spool 4 outer wall within a fitting offered for installing seal ring is not needed, greatly reduce component processing difficulty, also reduce processing cost simultaneously.
Arrange one for installing the deep gouge of rubbery flat gasket 6 by the threaded ends of pivot 2 within a fitting, and joint spool 4 is inserted in this rubbery flat gasket 6.When pivot 2 is threaded with outer silk nut 1 within a fitting, rubbery flat gasket 6 is subject to the extruding of outer silk nut 1 and joint maincenter 2 and is out of shape, and makes to be formed between joint maincenter 2 and peripheral nut to be tightly connected.And the joint spool 4 be inserted in rubbery flat gasket 6 is provided with spacing back-up ring 4a, the end of rubbery flat gasket 6 is withstood in spacing back-up ring 4a side, and opposite side is propped up bottom air chamber 1a by volute spring 7.Volute spring 7 ensure that the spacing back-up ring 4a of joint spool 4 compresses the end of rubbery flat gasket 6, is separated by the suction chamber 4b in the air chamber 1a of outer silk nut 1 and joint spool 4.
When the screw cap end of lock pin 9 along joint maincenter 2 is inserted, joint spool 4 ejects by the spring force that lock pin 9 overcomes volute spring 7 in rubbery flat gasket 6, makes suction port 4c as in air chamber 1a.The protruding 9a being simultaneously arranged on lock pin 9 front end sidepiece extrudes rubbery flat gasket 6, and formation is tightly connected.
The above, it is only preferred embodiment of the present utility model, not any restriction is made to technical scope of the present utility model, therefore every above embodiment is done according to technical spirit of the present utility model any trickle amendment, equivalent variations and modification, all still belong in the scope of the technical solution of the utility model.
