Abstract

The utility model discloses a joint of a butterfly two-hole wash basin tap water supply hose. A hexagon nut joint for connecting an outlet pipe with the inlet pipe of a tap is replaced by a butterfly nut joint. The joint has the advantages that the assembly and disassembly are convenient, security and watertight property can be ensured, and the phenomenon of water leakage since an installation person tightly twists the joint with great strength using a wrench by mistake can also be avoided.

Description

Butterfly diplopore washbowl tap water supply hose joint

Technical field:

The utility model belongs to the water tap intake pipe and connects the fastener constructions technical field.

Background technique:

Existing widely used diplopore washbowl tap water supply hose two ends attaching nut is the outer-hexagonal shape nut of M20, generally all can use the spanner of opening 24mm or about 8 cun adjustable spanner to come fastening when connection metope outlet pipe and leading intake pipe are installed.In fact in hose coupling hexagon nut bottom one flat rubber seal ring is arranged, and rubber seal all is the plane with contacting of joint, and the outlet pipe of leading intake pipe and body of wall all is the male-pipe of M20, middle water passage hole diameter is 16 millimeters, fallen the angle at port after the machining screw, form the annular edge of a knife of single face gradient at last, its with hose coupling in contacting of flat rubber seal ring be that ring-type is linear, its sealing effect is very reliable.But the problem of most critical is to use the spanner reinforcing when connection is fastening, only uses the strength of finger just can screw the purpose that reaches sealing.

Since, will pull for people's intuition exactly with spanner because existing flexible pipe joint outside all is made into outer-hexagonal shape.Always as pulling other tightening nut usually, it is tight more good more, tight more water-tight more to think in the process of pulling for a lot of people.In fact one side is arranged is linear sealing to the rubber ring in this nut, just can seal fully as long as fastening pressure, reaches more than 10 kilogram greater than inner pipe water pressure.And the axial pressure that the spanner of opening 24mm firmly is wrenched its generation of back for the screw rod of M20 can reach several tons, just begin to be damaged and work as up to a hundred kilograms of back plane rubber rings of its pressure by the cutting of the edge of a knife inclined-plane on pipe top, the metal covering that finally can form in pipe top and the joint directly contacts, and the sealing that has lost rubber pad causes the situation of leaking on the contrary.

Summary of the invention: the purpose of this utility model provides a kind of can conveniently the connection can avoid misleading the butterfly diplopore washbowl tap water supply hose joint that causes water leakage phenomenon after installation personnel tightens energetically with spanner for the deficiency that overcomes above-mentioned prior art existence just.

The purpose of this utility model realizes in the following way:

The technical solution of the utility model is to adopt the wing nut joint to replace existing hexagon nut joint at connection outlet pipe and leading intake pipe place, allowing installation personnel understand at a glance can only directly tighten with hand, and can not go to be wrenched energetically with spanner, reached both convenient, can guarantee the watertight effect of safety again.Real is a kind of update product preferably.

The beneficial effects of the utility model are, can conveniently install and change and can guarantee that safety is water-tight, can also avoid misleading and cause water leakage phenomenon after installation personnel tightens energetically with spanner.

Embodiment:

The utility model adopts the wing nut joint to replace existing hexagon nut joint at connection outlet pipe and leading intake pipe place.See Fig. 2, Fig. 3, Fig. 4 goes out to adopt wing nut at flexible pipe 1 joint

, allow installation personnel understand at a glance and can only directly tighten nut, and can not remove to be wrenched energetically nut with spanner with hand, reached both convenient, can guarantee the watertight effect of safety again, real is a kind of update product preferably.

Claims

1, butterfly diplopore washbowl tap water supply hose joint is characterized in that, adopts the wing nut joint to replace existing hexagon nut joint at connection outlet pipe and leading intake pipe place.
