Detailed Description
The principles and features of the present utility model are described below with reference to fig. 1 through 5, the examples being provided for illustration only and not for limitation of the scope of the utility model.
The utility model provides a high pressure cleaner pipe joint, includes urceolus 1 and inner tube 2, urceolus 1 has the inner chamber that link up, and the inner chamber of urceolus 1 is inserted to the one end of inner tube 2, and the one end that inner tube 2 inserted urceolus 1 is connected with bearing 17, and inner tube 2 and urceolus 1 form swivelling joint under the effect of bearing 17. A sealing ring 3 is further arranged between the outer cylinder 1 and the inner tube 2, so that the tightness of the connection between the outer cylinder 1 and the inner tube 2 is ensured.
The outer cylinder 1 is provided with a runner 4 communicated with the inner cavity of the outer cylinder, the tail end of the runner 4 is connected with a diaphragm 5 for sealing the runner 4, a puncture needle assembly 6 capable of puncturing the diaphragm 5 is slidably connected in the runner 4, and the diaphragm 5 is an aluminum film with the thickness smaller than 0.1 mm. Specifically: the flow channel 4 comprises a first branch 7 and a second branch 8 which are communicated with each other, and the first branch 7 and the second branch 8 form a human shape. Defining one end far away from the inner cavity of the outer cylinder 1 as the starting end of the first branch 7, and one end near to the inner cavity of the outer cylinder 1 as the tail end of the first branch 7; defining one end far away from the inner cavity of the outer cylinder 1 as the starting end of the second branch 8, and one end near the outer cylinder 1 as the tail end of the second branch 8; the first branch 7 is internally and spirally connected with a first plug 9, and the first plug 9 can slide in the first branch 7 to separate the second branch 8 from the inner cavity of the outer cylinder 1. The lancet assembly 6 is slidingly connected in a second branch 8; the puncture needle assembly 6 comprises a second plug 10 and a spring 11, and the second plug 10 always has a movement trend of sliding towards the inner cavity of the outer cylinder 1 under the action of the spring 11; the second plug 10 comprises a rubber part 12, a cylindrical part 13 and a needle body 14, wherein the rubber part 12 and the needle body 14 are respectively arranged at two ends of the cylindrical part 13, and the tail ends of the rubber part 12 and the second branch 8 are conical and are used for sealing the tail ends of the second branch 8.
