Abstract

A faucet injection structure comprises a water passage main body which is shaped in one time, a water outlet pipe and an outer shell, wherein the water passage main body which is shaped in one time is wrapped in the outer shell. A cold water inlet passage and a hot water inlet passage are arranged on the water passage main body which is shaped in one time, a cross beam is connected between the cold water inlet passage and the hot water inlet passage, a lateral core taking channel communicated with the cold water inlet passage, a lateral core taking channel communicated with the hot water inlet passage and a water outlet are arranged on the cross beam, a sealed plug is arranged on the lateral core taking hole on the water passage main body which is shaped in one time, and a tightening rib playing a tightening role is arranged on an outer shell corresponding to the sealed plug. In the structure of the utility model, a water passage on the faucet inner core body is injected and shaped integrally and then is covered on the inner core body which is shaped in one time through the outer shell, simultaneously, the outer shell also wraps the sealed plug on the lateral core taking hole on the water passage main body which is shaped in one time, thereby intensifying the intensity of the integral structure of the water passage main body which is shaped in one time, and improving the anti-leakage performance of the integral structure simultaneously.

Description

A kind of leading injection structure

Technical field

This novel a kind of leading water outlet device, particularly a kind of combination tap structure of relating to.

Background technique

The water tap of household use now has hot water or cold water's intake pipe more and is split into the water tap that mixes the water water outlet, and its leading inner core body structure is to be made of two vertical tubes and a transverse tube that is communicated with two vertical tubes, and this transverse tube middle part is for blending the mouth of a river with the fit adjustment valve.Present faucet body structure mostly is the metallic copper integrally casting and forms, metal has the requirement of strength that advantages of high strength can adapt to installation, but present resource comparatively lacks, and holding at high price of metal causes the cost of material of leading inner core body structure higher.In addition, this tap inner core body structure is the structure that is formed by three part three-way pipes, comparatively difficult when once-through, adopt to decompose partly and be welded again after the moulding, but two deficiencys can appear, the one, need to guarantee that two vertical tubes be arranged in parallel in same plane, two vertical tubes guarantee and the angle of inclination of transverse tube upper water-out mouth again simultaneously, hold than difficult during secondary operations; The 2nd, mostly each welding position that partly engages is the stress concentrated position, promptly when water tap is installed on the washbasin, the application of force direction of lock-connecting piece can make between vertical tube and the transverse tube and produce warping force, or in use, operation application of force direction on the tap, also can cause between vertical tube and the transverse tube and produce warping force, the existence of two kinds of factors very easily makes leading inner core body structure fracture take place and the working life of influence tap in the welding position.

In order to overcome the drawback that welding brings, people have adopted two-shot process, common way is to make the threeway inserts, on the threeway inserts, carry out quadric injection mould then, as shown in the figure, Fig. 6 is the threeway inserts, and Fig. 7 is the leading inner core body structure that the threeway inserts is adopted the quadric injection mould gained, A is quadric injection mould threeway inserts when location among the figure, the rib when adopting the extensional mode rib to be fixed on the mould of quadric injection mould.

Though this kind structure solved be welded to connect bring very easily make leading inner core body structure that fracture takes place in the welding position and the problem in working life of influence tap, but during owing to quadric injection mould, its inserts location adopts the extensional mode rib to be fixed on the mould of quadric injection mould, the quadric injection mould of this kind structure is when the junction plane combination force of the quadric injection mould of two parts is bad, can produce the junction plane leakage problems by being exposed to outer bead structures, this seepage still can not satisfy people's usage requirement, causes total to scrap.

The model utility content

This novel purpose is: designs a kind of novel leading injection structure, makes the water channel main body on the tap one-body molded, be convenient to install and use, make simply, prolong working life of tap, and easy to leak not.

The following structure of this novel employing realizes above-mentioned purpose, and a kind of leading injection structure comprises one-body molded water channel main body, outlet pipe, shell, and one-body molded water channel main body coats in the enclosure.

This one-body molded water channel main body is provided with cold intake tunnel, hot intake tunnel, be connected with crossbeam between cold intake tunnel and the hot intake tunnel, the side core-pulling passage that communicates with cold intake tunnel is arranged on the crossbeam, the side core-pulling passage that communicates with hot intake tunnel, water outlet, the above-mentioned side core-pulling passage that communicates with cold intake tunnel, the side core-pulling passage that communicates with hot intake tunnel, water outlet forms the one-body molded water channel main body of inner threeway, side core-pulling hole on the one-body molded water channel main body is provided with seal plug, outlet pipe is connected on the water outlet, shell divides goes up shell and lower casing, one-body molded water channel main body is positioned at shell, the through hole that the moulding water channel main body that is easy to be fixed as one is arranged on the shell is being provided with the chucking rib of chucking effect with the corresponding shell of seal plug place.

One-body molded water channel main body and outlet pipe place in the shell,

The chucking rib is located on the shell.

Seal plug is provided with the seal groove of placing seal ring.

Adopt the as above a kind of novel leading injection structure of structural design, the water channel on the leading inner core body is one-body molded, and the water channel main body that is formed in one does not need quadric injection mould, once finishes leading inner core body injection structure.Overcome in the prior art, make the threeway inserts earlier, by quadric injection mould the threeway inserts is injected into leading inner core body structure more then, water channel on the leading inner core body needs finish by quadric injection mould, thereby makes the shortcoming that the water channel of leading inner core body is easy to reveal; Adopt the leading injection structure of this novel making, technology is simple, and integrated injection molding of the water channel on the leading inner core body makes that leading inner core body structure is firm more and is difficult for leakage.

In this new structure, water channel integrated injection molding on the tap inner core body, cover on the integrated inner core body by shell again, shell also coats the seal plug on the side core-pulling hole on the one-body molded water channel main body together simultaneously, promptly strengthen the integrally-built intensity of one-body molded water channel main body, improved integrally-built leakage proof simultaneously again.

This is novel to have, simple in structure, good integrity, and easy processing, advantage such as easy to leak has not prolonged leading working life.
