Detailed Description
The following detailed description of specific embodiments of the utility model refers to the accompanying drawings.
A quick-plugging sealing joint comprises a main body joint 1 and a sleeve nut 6.
As shown in figure 1, the front end of the main body joint 1 is integrally provided with an external thread joint 2, a middle hole 3 is integrally formed in the main body joint 1 and the external thread joint 2, a sealing ring groove 4 is formed in the middle hole 3 of the external thread joint 2, and a sealing ring 5 is arranged in the sealing ring groove 4.
As shown in fig. 1, the inner cavity wall of the outer nut 6 is provided with an internal thread 7 for installing the male connector 2, the bottom of the inner cavity of the outer nut 6 is provided with a cone bottom cavity 8, and a plug 10 is installed in the cone bottom cavity 8 of the outer nut 6.
As shown in fig. 1, a core 11 inserted into the hole of the male connector is provided at the front end of the plug 10, and a core hole 15 is integrally provided in the plug 10 and the core 11. The core print 11 is inserted into the central hole 3 and then is in sealing contact with the seal ring 5.
