Description

Water tap

Technical field

The present invention relates to a kind of non-metal tap, especially divide the bindiny mechanism of the outlet pipe and the leading main casing of body structure.

Background technique

As shown in Figure 1, outlet pipe of Chu Xianing and leading main casing are that plug-in unit was linked up exhalant canal in outlet pipe and the leading main casing in the middle of the water tap of split type structure generally adopted in the market, the end that middle plug-in unit and outlet pipe are pegged graft has seal ring, the other end is threaded with leading main casing, middle plug-in unit is by through hole on the leading main casing and the conducting of valve seat osculum, the bottom of outlet pipe generally also is provided with screw hole, by being screwed into, screw withstands middle plug-in unit in the screw hole, thereby plug-in unit can be arranged on outlet pipe on the leading main casing in the middle of making, liquid sealing is only implemented by seal ring in the leading main casing of this water tap and the joint of outlet pipe, therefore often sealing effect is relatively poor, and the sound construction that being threaded of adopting of middle plug-in unit two ends is connected with plug bush type is relatively poor, and outlet pipe is rocked.

Summary of the invention

Technical problem to be solved by this invention provides a kind of water tap, and the sealing effect of the outlet pipe of this water tap and the joint of leading main casing is better, it is more firm to be connected.

For this reason, water tap provided by the invention comprises leading main casing, the tap main casing has the outlet pipe of valve seat and structure split type with it, this outlet pipe is fixed on the leading main casing by first bindiny mechanism, described first bindiny mechanism comprises intermediate connector, intermediate connector has intermediate throughholes, this intermediate connector and the mutual socket of leading main casing, intermediate connector is fixed on the leading main casing by second bindiny mechanism, the exterior edge face of intermediate connector and outlet pipe end face mate mutually and interfix, intermediate throughholes and the conducting of outlet pipe inner passage, have the 3rd bayonet end on the intermediate connector, the end of the 3rd bayonet end has first craft port towards upper shed, this first craft port and intermediate throughholes conducting, the lower end of valve seat has second craft port, this second craft port and the conducting of valve seat osculum, first craft port is docked with second craft port and conducting, on the leading main casing to offering fourth hole by the 3rd bayonet end.

Because water tap provided by the invention disposes intermediate connector, intermediate connector and the mutual socket of leading main casing, the end face of intermediate connector and outlet pipe end face interfix, fixing mode generally can adopt the welding rod welding, the mode that ultrasonic welding or glue are bonding, this fixing mode is closely fixing with intermediate connector and outlet pipe, and intermediate connector except with leading main casing socket, also overlap second bindiny mechanism and be fixed on the leading main casing by other one, make the fixing more firm of intermediate connector and leading main casing, discuss above comprehensive, each bindiny mechanism of relating to of outlet pipe and leading main casing is more firm in the present invention, protection is better, and because intermediate connector also disposes second bindiny mechanism guarantee intermediate connector with leading main casing fixing except the mode that adopts sleeve and the outlet pipe fixed on it can arbitrarily not rock, so its liquid sealing effect more is better than existing water tap of the same type.In addition, because the existence of intermediate connector makes the outlet pipe injection moulding of can loosing core separately, and needn't worry that the outlet pipe outlet port is too crooked to the passage of outlet pipe inner end, be inconvenient to loose core, this outlet pipe can be directly from inner end and outer end two to loosing core, make the shape of outlet pipe more changeable, have more condition to design outlet pipe shape more attractive in appearance, be particularly useful for nonmetallic water taps such as plastic material.
