Example four
In order to facilitate separation of the sealed quick-release pipe joint from the fluid port and adjust tightness of connection between the sealed quick-release pipe joint and the fluid port, the embodiments of the present application are designed based on the sealed quick-release pipe joint in the first embodiment or the second embodiment.
The sealed quick assembly disassembly coupling still includes: a lock nut 70;
the outside of the fluid barrel 20 is provided with a second external thread 24;
the lock nut 70 is secured to the fluid barrel by the second external threads 24 and is located on the exterior of the fitting housing 10.
In practical applications, the distance between the fluid barrel spring stop 22 and the top of the connector housing, i.e., the amount of compression of the abutment spring 30, can be adjusted by adjusting the position of the locking nut 70 on the fluid barrel 20 by turning the locking nut, thereby adjusting the amount of spring force generated by the abutment spring 30 and thus adjusting the tightness of the abutment of the interface seal ring 40 against the outer edge of the fluid interface 90.
In addition, when the sealed quick-release pipe joint is disassembled from the fluid port 90, an operator applies an acting force to the joint housing 10 in a direction opposite to the butt direction, so that the joint housing 10 moves in the direction opposite to the butt direction, and when the top of the joint housing abuts against the lock nut 70, the joint housing 10 drives the fluid barrel 20 to move in the direction opposite to the butt direction, so that the guide nozzle 21 is separated from the fluid port 90, and the disassembly of the sealed quick-release pipe joint is completed.
According to the embodiment of the application, the locking nut which is in threaded connection with the fluid barrel is additionally arranged in the sealed quick assembling and disassembling pipe joint and is arranged on the outer side of the joint shell, the locking nut is rotated to move in the length direction of the fluid barrel, so that the distance between the locking nut and the spring stop part is changed, the distance between the top of the joint shell and the spring stop part can be changed, namely the compression length of the abutting spring is changed, the elasticity of the abutting spring is adjusted, the tightness of the abutting of the interface sealing ring and the outer edge of the fluid interface is adjustable, and the flexibility of the sealed quick assembling and disassembling pipe joint is enhanced; in addition, the locking nut fixed on the fluid gun barrel is used for moving the joint shell to enable the joint shell to be abutted against the locking nut, so that acting force which is applied to the joint shell and is opposite to the butt joint direction can be transmitted to the fluid gun barrel, separation of the guide nozzle and the fluid interface can be realized, and force application by an operator is facilitated.
