Detailed Description

The technical solution in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of , but not all embodiments.

Referring to fig. 1-6, novel hydraulic leakage-proof faucet comprises a faucet shell 1, a handle 2, a filter screen bolt 3, a filter screen 31, a return spring 4, a piston type water inlet bolt sealing sheet 5, a water inlet control bolt 6, a water inlet control switch 7, a sealing spring 8, a fastening bolt 9 and a shaft seat 70, wherein the piston type water inlet bolt sealing sheet 5 comprises a water inlet bolt sealing sheet 51 and a water inlet control cam driven push rod 52, and the water inlet control switch 7 comprises a water inlet control cam 71, a fastening bolt sealing sheet 72 and a water inlet control cam shaft 73.

This novel fluid pressure type leak protection tap, when opening, user twist grip 2, it is rotatory to drive into water control switch 7, it advances water control cam driven push rod 52 to advance the oval major axis bulge of control cam 71 outward flange on the control switch 7 that advances, lead to advancing water control cam driven push rod 52 level and remove left, because it is mould times injection moulding integrated into one piece structure with advancing water control cam driven push rod 52 to advance water bolt gasket 51, it advances water bolt gasket 51 with the level that advances water control cam driven push rod 52 plays the level and remove left, it extrudes return spring 4 to advance water bolt gasket 51, lead to simultaneously advancing water bolt gasket 51 and the sealed inefficacy between the through-hole 61, rivers get into the inside cavity of tap through the through-hole 61, from exhalant canal 102 outflow.

When the water faucet is closed, a user rotates the handle 2 to drive the water inlet control switch 7 to rotate, the circular short-shaft non-protruding part on the outer edge of the water inlet control cam 71 on the water inlet control switch 7 is in contact with the driven push rod 52 of the water inlet control cam, so that the driven push rod 52 of the water inlet control cam is horizontally moved rightwards to reset, the water inlet bolt sealing sheet 51 and the driven push rod 52 of the water inlet control cam are of an integral molding structure of a mold times of injection molding, the water inlet bolt sealing sheet 51 and the driven push rod 52 of the water inlet control cam horizontally move rightwards, under the action of the self pressure of tap water and the reset action of the return spring 4, firm sealing is generated between the water inlet bolt sealing sheet 51 and the water inlet through hole 61.

The water inlet bolt sealing sheet 51 is uniformly stressed and is uniformly worn in the using process, even if the water faucet is used for a long time, the water inlet bolt sealing sheet 51 can generate firm sealing effect on the water inlet through hole 61 under the pressure of tap water and the reset effect of the return spring 4, the water leakage phenomenon caused by the rotary abrasion between the ceramic moving sheet and the ceramic fixed sheet in the using process of the traditional water faucet is effectively solved, a small gap is generated by the long-term abrasion between the water inlet control cam shaft 73 and the fastening bolt 9, the water leakage phenomenon caused by the abrasion between the water inlet control cam shaft 73 and the water faucet shell 1 is effectively solved because the fastening bolt sealing sheet 72 on the body-formed water inlet control switch 7 is tightly attached to the lower end face of the fastening bolt 9 under the pressure of the tap water, the water leakage phenomenon caused by the abrasion between the rotary shaft sealing ring of the traditional water faucet and the sealing sheet water inlet control switch 7 is effectively solved, the handle 2 can be rotatably opened and closed at 360 degrees under the interaction between the piston type water inlet bolt 5 and the sealing.

In summary, the novel hydraulic leakage-proof faucet adopts the integral molding structure of times of injection molding processing by the mold, so that the problem that the water leakage phenomenon is easy to occur in the use process of the faucet is effectively solved.
