Description

A kind of tap water outlet bend pipe rotating core

Technical field

The utility model relates to a kind of rotary water tap connectors, more particularly to a kind of tap water outlet bend pipe rotating core.

Background technique

Faucet valve body needs to install leading rotating core, passes through the effect of leading rotating core when assembly is discharged Discharging bent-tube Carry out any rotary faucet with this.And leading rotating core be it is fixed, in rotary faucet, the O of tap water outlet bend pipe and rotating core Type circle rubs, and O-ring carries out friction for a long time and is easy to break down, if O-ring is too big, frictional force is big, not handy, too small, Can leak, influence using.

Utility model content

The purpose of this utility model is to provide a kind of tap water outlet bend pipe rotating cores, to solve existing leading rotating core The problem of O-ring is easy to wear and leak.

Technical solutions of the utility model are as follows: a kind of tap water outlet bend pipe rotating core, including central spindle, turning set, oil sealing, anti- Dirt lid and E type snap ring；Central spindle upper end outer peripheral wall is equipped with the groove of an indent along its circumferential direction；The central spindle lower end It is equipped with connection screw thread；The connection screw thread upper end is equipped with the snap ring of a protrusion；A gear chassis is installed on the snap ring； The turning set is sheathed on the middle and upper part of central spindle, and the upper end inner sidewall of turning set is engaged with oil sealing；The dustproof cover It is placed at the top of turning set；The E type snap ring is set at the top of dustproof cover, and is fixed in the groove in central spindle.

Preferably, several slots are equipped at the top of the gear chassis；The gear tray bottom is equipped with a positioning groove, passes through Locating slot realization gear chassis chimeric with the positioning of the locating piece on snap ring is fixedly connected with central spindle.

Preferably, the turning set lower end offers a slot, is equipped with a gear spring in the slot；The gear spring It is inside fixed with a gear pearl, and is connect with gear chassis.

Preferably, the slot frictional connection of the gear pearl and gear chassis.

Preferably, gear chassis lower end is convexly equipped with an edge department.

Preferably, at least two inner groovies, each inner groovy are equipped with along its circumferential direction on the jacket wall of the turning set On be installed with sealing ring.

As can be seen from the above description, compared with prior art, the utility model has the advantages that

1, for the rotating core in rotation, O-ring and Discharging bent-tube do not generate friction, are converted to oil sealing and the rotation of the inside Set rubs, and oil sealing is more wear resistant, greatly reduces coefficient of friction, and gear pearl and the slot on gear chassis of turning set rub It wipes, clear and melodious sound can be issued, more there is class；

2, the rotation set upper side of the rotating core is connect with oil sealing, plays the role of sealing；The setting of dustproof cover plays Effect that is dust-proof and preventing oil sealing from moving up and down, finally fixes entirety by E type snap ring, prevents central spindle from separating with other component；

3, the damage that the rotating core not only avoids O-ring from being subject to by friction, leakproofness is stronger, and also enhances rotating core Service life.
