The specific using process is as follows: the hexagonal long tube 1 and the threaded end 2 are connected together by a user in a threaded connection, wherein the second oil liquid pipe 6 is inserted into the inner cavity of the threaded surface 10 and extends out of the hexagonal long pipe 1 until the first end 7 of the oil liquid pipe is abutted against the side wall of the inner cavity of the hexagonal long pipe 1, namely one side of the interior of the hexagonal long pipe 1 close to the through opening, then the metal gasket 8 is tightly attached to the end head 7 of the oil pipe, the threaded end head 2 is inserted into the inner cavity of the hexagonal long pipe 1 and is screwed through the threaded surface 10, before the threaded end 2 is inserted into the inner cavity of the hexagonal long tube 1, the oil pipe end two 9 on the oil pipe one 5 is inserted into the inner cavity of the hexagonal long tube 1, then the metal washer 8 is contacted with the metal washer 8, the second oil pipe end 9 is pushed to be slowly extruded along with the screwing of the threaded end 2, the metal washer 8 is tightly fixed between the first oil pipe end 7 and the second oil pipe end 9 by matching with the first oil pipe end 7, thus, the threaded end 2, the hexagonal short pipe 4, the first oil pipe 5, the second oil pipe 6, the first oil pipe end 7, the metal gasket 8, the second oil pipe end 9 and the metal gasket 8 can form a complete and sealed oil passage, wherein the position of the oil leakage self-checking hole 3 is positioned between the first oil pipe end 7 and the second oil pipe end 9, therefore, if a gap is formed between the first oil pipe end 7 and the second oil pipe end 9, oil can seep out from the gap and then flows out from the inspection hole 3 through the leaked oil, which is a problem in the sealing property of the joint and has an oil leakage condition, if no oil is exposed from the oil leakage self-checking hole 3, it is proved that the sealing performance of the joint is not problematic, and the oil leakage condition cannot occur.

The inner wall of the hexagonal long tube 1 close to one half of the opening is provided with a threaded surface 10 matched with the threaded end 2, the inner wall of the other half of the hexagonal long tube 1 is a smooth surface, and the two oil seepage self-checking holes 3 are formed in the inner wall of the smooth surface of the hexagonal long tube 1.

Specifically, the screw thread surface 10 is used for being connected with the screw thread end 2, and it occupies half of the internal cavity of the hexagonal long tube 1, and the smooth surface is used for setting the oil leakage self-checking hole 3, so that the oil is prevented from permeating to other positions inside the hexagonal long tube 1, and the oil occupies half of the internal cavity of the hexagonal long tube 1.

All seted up breach 11 on two relative facets in surface of hexagonal type long tube 1, the inside of breach 11 is rotated through the pivot and is installed clamp subassembly 12, all set up the draw-in groove 13 with clamp subassembly 12 looks adaptation on two relative facets in surface of hexagonal type nozzle stub 4, clamp subassembly 12 includes two pivot pins 124 of fixed connection on the inner wall of breach 11 both sides, and there are pivot cover one 122 and pivot cover two 123 on the surface of two pivot pins 124 respectively movable mounting, one side fixedly connected with returning plate 121 of pivot cover one 122 and pivot cover two 123, one side integrated into one piece of returning plate 121 is connected with the fixture block 126 with draw-in groove 13 looks adaptation, the back of returning plate 121 is provided with reset subassembly 125, pivot cover two 123 is including wrapping up nest plate one 1231 and nest plate two 1232 on one of them pivot pin 124, the outside fixedly connected with two strengthening ribs 1234 of nest plate one 1231, the equal fixed connection of one end of two strengthening ribs 1234 on returning plate 121, the outside fixedly connected with two strengthening ribs 1233 of nest plate 1232, two strengthening ribs 1233 all fixed connection on two returning plate 121.

Specifically, screw up the in-process of installation at thread end 2, the fixture block 126 can be taken first to touch by two oil pipe ends 9, then prop open two fixture blocks 126 to the outside, wherein returning face plate 121 can be through pivot cover 122 and the upset of pivot cover two 123, then returning face plate 121 can stretch reset subassembly 125, then after thread end 2 enters into hexagonal prism type long tube 1's inside completely, draw-in groove 13 also can be in suitable position, then returning back under reset subassembly 125's effect returning of returning face plate 121 and fixture block 126, the inner chamber to draw-in groove 13 can then be blocked into to fixture block 126, thereby carry out fixing once more to thread end 2, also guarantee whole articulate's fastness.

Reset assembly 125 includes two links 1251, and two links 1251 are fixed connection respectively on the inner wall of breach 11 and returning face plate 121, and couple 1252 has all been articulated in the outside of two links 1251, is provided with reset spring 1253 between two couples 1252, reset spring 1253's both ends are fixed connection respectively on two couples 1252.

Specifically, can drive one of them link 1251 and couple 1252 extension reset spring 1253 when returning face plate 121 expandes, then after draw-in groove 13 reachd suitable position, through reset spring 1253 self elasticity, can also contract and pull back returning face plate 121 and fixture block 126, so fixture block 126 just can block the inner chamber of draw-in groove 13 to pull down in the reset spring 1253 shrink, fixture block 126 can block always in draw-in groove 13, difficult roll-off.

The diameter of the second oil pipe end 9 is larger than the aperture of the threaded end 2, and the diameter of the second oil pipe end 9 is smaller than the inner diameter of the hexagonal long pipe 1.

Specifically, the second oil pipe end 9 can be abutted to the end of the threaded end 2 and can extend into the hexagonal long pipe 1, and under the pushing of the threaded end 2, the second oil pipe end is matched with the first oil pipe end 7 to form an extrusion state on the metal gasket 8, so that the sealing performance of the oil duct is ensured.

The opening has been seted up to the one side that just keeps away from flank of thread 10 to the inner chamber of hexagonal edge type long tube 1, and the internal diameter of opening is less than the internal diameter of hexagonal edge type long tube 1, metal packing ring 8 contradicts on the inner wall that hexagonal edge type long tube 1 is close to opening one side.

Specifically, because the inner diameter of the opening is smaller than that of the hexagonal long tube 1, a threshold is formed at the connection part of the opening and the inner cavity of the hexagonal long tube 1, so that the first oil tube end 7 is blocked, and the first oil tube end 7 can extrude the metal washer 8.

The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
