Detailed Description

As shown in figures 1, 2 and 3, the stably-connected water supply and drainage pipe comprises a water supply and drainage pipe I1 and a water supply and drainage pipe II 2, wherein a connecting pipe II 3 is sleeved on the outer thread of the water supply and drainage pipe II 2, the connecting pipe II 3 extends out along the water supply and drainage pipe II 2, the side wall thickness of the connecting pipe II 3 is gradually reduced from the thread sleeved end to the extending end of the connecting pipe II, a limiting bulge 7 for secondary water prevention and separation prevention is fixedly arranged on the inner side wall of the extending end of the connecting pipe II, which is close to the edge of the connecting pipe II, along the circumferential direction, one end of a connecting pipe I4 is sleeved on the outer thread of the water supply and drainage pipe I1, a sliding groove 5 for inserting the extending end of the connecting pipe II 3 is arranged in the side wall of the other end of the connecting pipe I4 along the axial direction, friction bulges 6 for tightly propping against the connecting pipe II 3 and preventing water leakage are fixedly arranged on the, namely, the radial dimension of the outer end of the sliding chute 5 is smaller than that of the inner end thereof; and the extending end of the connecting pipe II 3 is inserted into the sliding groove 5 to be clamped and fixed.

In order to facilitate the extension end of the connecting pipe II 3 to enter the sliding groove 5 and prevent the connecting pipe II 3 from separating from the sliding groove 5, the outer side surface of the limiting protrusion 7 is an arc-shaped surface, and the inner side surface is a plane, as shown in fig. 4. The medial surface of spacing arch 7 is the plane, and when it and the protruding 6 contacts of friction, two planes just contact and the card is in the same place, and connecting pipe II 3 can not break away from spout 5.

In order to further prevent water leakage in advance, the sum of the thickness of the limiting bulge 7 and the thickness of the corresponding position of the extending end of the connecting pipe II 3 is consistent with the radial size of the inner end of the sliding groove 5, so that the limiting bulge 7 can form a jacking force on the side wall of the inner end of the sliding groove 5, and water leakage from the friction bulge 6 can be prevented from flowing outwards.

Preferably, the inner side surface and the outer side surface of the extending end of the connecting pipe II 3 are both provided with concave-convex patterns for increasing friction force.

Preferably, the friction protrusions 6 are wear-resistant rubber protrusions having micro-elasticity.

The during operation, it is earlier right the utility model discloses a plumbing pipe installs, and the installation step is: only need to have screw sleeve joint connecting pipe II 3 outward respectively with water supply and drainage pipe I1 and water supply and drainage pipe II 2, connecting pipe I4, then insert the spout 5 of connecting pipe I4 with the end that stretches out of connecting pipe II 3 in, as shown in fig. 1, friction arch 6 this moment, spacing arch 7 carries out radial top tightly to the end that stretches out of connecting pipe II 3 respectively, its top tight power is obtained according to the thickness of predicting high water impact force regulation friction arch 6 and spacing arch 7, it is suitable that the end that stretches out of connecting pipe II 3 takes place less displacement in spout 5 when the high water impact.

When high water flow strikes, the end that stretches out of connecting pipe II 3 takes place less displacement in spout 5, and the impact force acts on the joint portion of connecting pipe II 3, connecting pipe I4, can not act on the spiro union portion of plumbing pipe I1 and plumbing pipe II 2 to increase the life-span of plumbing pipe, and need not to reform transform the link of current plumbing pipe.

The distance between the friction bulge 6 and the limiting bulge 7 is the maximum distance capable of sliding, when the connector is used for a period of time, the friction bulge 6 and the limiting bulge 7 are in contact clamping connection, and a maintenance worker can insert the connecting pipe II 3 into the sliding groove 5 regularly, so that the distance between the friction bulge 6 and the limiting bulge 7 is recovered to the initial state shown in the figure 1. When the friction bulge 6 and the limit bulge 7 are seriously worn to be incapable of sealing the inner cavity, a layer of rubber can be adhered on the inner side surfaces of the friction bulge 6 and the limit bulge 7.

What has been described above is only the preferred embodiments of the present invention, and it should be noted that, for those skilled in the art, without departing from the overall concept of the present invention, a plurality of changes and improvements can be made, and these should also be regarded as the protection scope of the present invention, and these will not affect the effect of the present invention and the utility of the patent.
