the external diameter that is close to the one end of constant diameter section 1 on the convergent section 2 equals with the external diameter of constant diameter section 1, the external diameter of convergent section 2 is linear reduction to the one end of keeping away from constant diameter section 1 by the one end that is close to constant diameter section 1, be equipped with a plurality of snap rings 21 of arranging along the axis direction on the outer peripheral face of convergent section, it is a plurality of the diameter of snap ring 21 is cascaded degressive to the one end of keeping away from constant diameter section 1 by the one end that is close to constant diameter section 1.
In clinical work, when needing to use attach fitting to connect the pipe fitting, only need locate 2 outsides of convergent section with the tip cover of pipe fitting, because the snap ring 21 diameter of convergent section 2 is the echelonment and changes, consequently to the pipe fitting of not unidimensional, can both locate behind the convergent section 2 by the snap ring 21 of suitable diameter the joint to keep fixed, just so can guarantee that the pipe fitting of not unidimensional can both connect through the multi-functional attach fitting of same model.
Examples
As shown in fig. 1 and 2, the multifunctional connector is a hollow tube, and the multifunctional connector is a plastic connector, compared with a conventional glass connector, the plastic connector has certain flexibility and deformation capability, so that the phenomenon that the interior of a pipe is not smoothly closed due to bending of the joint of a flexible pipe and the connector can be avoided, and the plastic connector is not fragile and is easy to insert and connect the pipe;
the multifunctional connecting joint comprises an equal-diameter section 1 and two reducing sections 2 symmetrically arranged at two ends of the equal-diameter section;
the inner diameter and the outer diameter of each position of the equal-diameter section 1 in the axial direction are both constant values;
the outer diameter of one end, close to the equal-diameter section 1, of the reducing section 2 is equal to that of the equal-diameter section 1, the outer diameter of the reducing section 2 is linearly reduced from one end, close to the equal-diameter section 1, to one end, far away from the equal-diameter section 1, of the reducing section, a plurality of clamping rings 21 arranged along the axis direction are arranged on the outer peripheral surface of the reducing section, and the diameters of the clamping rings 21 are gradually reduced from one end, close to the equal-diameter section 1, to one end, far away from the equal-diameter section 1;
