Detailed Description
The following is a specific embodiment of the present invention, which will be further described with reference to the accompanying drawings.
Referring to fig. 1 to 3, the left end of the joint body 6 is used for being connected with an oil port, and the right end of the joint body 6 is provided with a mounting counter bore. An internal thread 6-1 and a U-shaped clamping groove opening I6-2 are arranged in a mounting counter bore of the connector body 6, the internal thread 6-1 is arranged at the right end of the mounting counter bore of the connector body 6, and the U-shaped clamping groove opening I6-2 is positioned at the left side of the internal thread 6-1. The bottom surface of the counter bore for installing the joint body 6 is a plane.
The left end of the quick-mounting straight-through joint core 8 is inserted into a counter bore of the joint body 6 in a matching mode, the left end face of the quick-mounting straight-through joint core 8 is a plane, a sealing groove 8-1 is formed in the left end face of the quick-mounting straight-through joint core 8, and an O-shaped sealing ring 7 is installed in the sealing groove 8-1. The circumferential surface of the left end of the quick-assembly straight-through joint core 8 is provided with a locking external thread 8-3 matched with the internal thread 6-1 of the joint body 6 and a U-shaped clamping groove opening II 8-2 matched with the U-shaped clamping groove opening I6-2 of the joint body 6. The internal thread 6-1 and the locking external thread 8-3 play a role in accurate positioning when the O-shaped ring is close to the top of the joint, the sealing length of the threads is controlled within 5mm, and the positioning is ensured to be rapid. U-shaped cards 9 are arranged on the U-shaped card slot I6-2 and the U-shaped card slot II 8-2.
