Description
Technical field
The utility model is related to a kind of hyperbolic water inlet pipe and water outlet pipe.
Background technology
Hyperbolic water inlet pipe and water outlet pipe is the water inlet pipe and water outlet pipe in a kind of sanitary bath equipment used in water heater, for connecting two height not
Accordant interface, in order to using being threadedly coupled, two bendings are provided with hyperbolic water inlet pipe and water outlet pipe.Reference picture 4, due to hyperbolic turnover
Water pipe is provided with two bendings, and in injection moulding, traditional way is using three-stage core pulling, in hyperbolic water inlet pipe and water outlet pipe
Between one end of section be provided with opening 4 for core pulling, reuse plug and seal the opening.This structure one side plug easily leaks
, there is hidden danger in water；On the other hand, complex structure is used, it is necessary to assemble, and improves cost, and hyperbolic water inlet pipe and water outlet pipe is integrally accounted for
It is more with space, easily interference with miscellaneous part.
The content of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of hyperbolic water inlet pipe and water outlet pipe, simple structure, cost
It is low.
The utility model solves the technical scheme that its technical problem used：
A kind of hyperbolic water inlet pipe and water outlet pipe, includes interior tube body and outer tube body, and said inner tube body is provided with joint and bend pipe, institute
State bend pipe and be provided with a bending, the outer tube body is using injection moulding integrated molding in the outside of interior tube body, the outer tube body cladding
Bend pipe, the outer tube body is provided with two bendings.
As the improvement of above-mentioned technical proposal, latticed fin is provided with the bend pipe outer wall.
As the further improvement of above-mentioned technical proposal, it is provided with the bend pipe outer wall for being positioned in injection mold
Locating convex block.
Further improve, the joint is connected with metal threaded joint.
Further improvement, the metal threaded joint and interior tube body integrated injection molding.
Further improve, the fixture block of multiple radial protrusions is provided with the inwall of the metal threaded joint.
Further improve, the joint is provided with circumferential four uniform planes near the end of bend pipe.
Further improve, twisting plane corresponding with the plan-position is provided with the outer tube body.
Further improve, the outer tube body is provided with the pipe joint for connecting pipe, the pipe away from the end of joint
Joint is provided with groove and sealing inclined-plane for installing sealing ring.
The beneficial effects of the utility model are：Hyperbolic water inlet pipe and water outlet pipe is decomposed into interior tube body and outer tube body, using noting twice
It is moulded the mode of type, first time injection moulding interior tube body, due to the bending of interior tube body only one of which, so from two ends core pulling；
Second injection moulding outer tube body, by the use of interior tube body as inner core, as long as setting a core pulling.Cladding after outer tube is body formed
The bend pipe of interior tube body, is eliminated opening and is sealed using plug, eliminates the hidden danger of leak.The utility model simple structure reality
With sealing and anti-leakage, low cost.
Brief description of the drawings
The utility model is described in further detail with reference to the accompanying drawings and examples.
Fig. 1 is structural representation of the present utility model；
Fig. 2, Fig. 3 are decomposing schematic representations of the present utility model；
Fig. 4 is the structural representation of traditional hyperbolic water inlet pipe and water outlet pipe.
Specific embodiment
A kind of 1 ~ Fig. 3 of reference picture, hyperbolic water inlet pipe and water outlet pipe includes interior tube body 1 and outer tube body 2, and said inner tube body 1 is provided with
Joint 11 and bend pipe 12, the bend pipe 12 are provided with a bending, and the outer tube body 2 is using injection moulding integrated molding in interior tube body
1 outside, the cladding bend pipe 12 of the outer tube body 2, the outer tube body 2 is provided with two bendings.In order to promote interior tube body 1 and outer tube
Body 2 is closely connected, it is preferred that be provided with latticed fin 121 on the outer wall of the bend pipe 12 so that after the injection moulding of outer tube body 2
It is close on interior tube body 1, while avoiding loosening, shifting；Preferably, it is provided with injection mold on the outer wall of the bend pipe 12
The locating convex block 122 of middle positioning, position, angle of the interior tube body 1 in mould are ensured by the cooperation of locating convex block 122 and mould
Accurately.Using said structure, by the way of injection moulding twice, first time injection moulding interior tube body 1, due to interior tube body 1
There is a bending, so from two ends core pulling；Second injection moulding outer tube body 2, by the use of interior tube body 1 as inner core, as long as
One core pulling is set, and outer tube body 2 coats inner tube after being molded, 1 bend pipe is eliminated opening and sealed using plug, disappeared
Except the hidden danger of leak, service life is improved.
For the ease of connecting other pipelines, in the present embodiment, it is preferred that the joint 11 is connected with metal threaded joint
3 so as to connecting pipe, valve.In order to improve the steadiness of metal threaded joint 3, it is preferred that the metal threaded joint 3 with it is interior
The integrated injection molding of body 1, is provided with the fixture block 301 of multiple radial protrusions on the inwall of the metal threaded joint 3, in injection
The fixture block 301 that joint 11 is coated on the inwall of metal threaded joint 3 during shaping makes both connect more closely, and structure is more firm, it is to avoid
Loosen.
In the present embodiment, it is preferred that the joint 11 is provided with circumferentially uniform four and puts down near the end of bend pipe 12
